Abstract

The panels for constructing a cover, in particular, a floor cover are provided with elements (18) in the form of a rod or a string which is located in a gap (11) between two such panels (1, 2). Also claimed is a resultant cover.

Description

The invention relates to components for the provision of a covering. The components comprise in particular a panel, which with a second panel can be positively connected, so that one Locking both perpendicular to the common surface as also perpendicular to the joint joint and at the same time parallel to the common surface, the use of Glue can then be dispensed with, if the panels according to the invention as a covering for a floor or a Wall paneling can be used.

A panel of the type mentioned is for example from the US Pat. No. 6,324,803 B1 or EP 0 698 162 B1. The known panel is connected to a second by means of a tongue and groove connection perpendicular to the common surface of the panels positively locked. The groove comprises an upper and a lower flank. The lower flank is longer than the upper one and faces at the end of a protruding locking element. in the Connected state locks the protruding locking element in a recess, which is below the adjacent panel is introduced, This is a positive locking scored, which is parallel to the common surface of the two Panels and at the same time perpendicular to the joint of the both panels works.

In the locked state of two panels remains between the protruding locking element and the recess a Game, so among other things, one panel relative to the other Slightly moved along the joint can be. The transition from the leading edge to Locking element runs vertically. The locking element protrudes vertically into the air. The recess below the adjacent panel has walls that are perpendicular to the common surface of the panels run. So it hits a vertical wall or, contact surface of Recess on a vertical wall or, Contact surface of the protruding locking element in locked state, this ensures that the Panels in the installed state at larger Force can not accidentally solve each other.

The game is also required in spite of the aforementioned vertical walls two panels, for example by a Rotary movement around the joint joint around To be able to connect, In the aforementioned document is indicated that a clearance of 2/10 mm may be present.

The material from which the panels of the type mentioned can exist in principle, is freely selectable. According to the invention however, in particular, panels affected completely or mainly consist of a wood material, at one Parquet panel this can be made entirely of wood. Alternatively, a parquet panel may comprise a backing plate which For example, HDF or MDF, Above the Support plate are applied one or more parquet lamellae. Below the carrier plate may be a layer or a paper be upset to effect a return Avoid deformations. They are also glutinous with each other Connectable panels are known that are wholly or predominantly made Plastic consist, for example, from the document US 04,426,820th

The invention further relates in particular to a Laminate flooring. This comprises a carrier plate of a Wood-based material, HDF and MDF are currently being used as the wood material prefers. Another typical wood material consists of glued chips, Above the support plate is a decorative layer applied, which is a decorative paper together with a protective layer includes. The protective layer consists in particular of a resin, which, inter alia, abrasion-resistant particles such as corundum or SiC having. Below the carrier plate is a Gegenzugpapier applied in order to avoid the aforementioned deformations.

Currently there are signs that technical laminates on Importance will be gained and from this increasingly panels getting produced. These are used in particular as a floor covering used.

Resin-soaked papers are co-produced in the manufacture the support plate fed to a press, under supply of heat and printing the papers are glued to the carrier plate. there the decor paper already has the layer with the abrasion-resistant Particles on.

Panels of the type according to the invention may contain one or more of the include the aforementioned features.

The above-mentioned game was considered too disadvantageous by experts felt, because in this dust and moisture to penetrate can, visually the game is perceived as negative because A gap may occur on the surface.

To avoid such a game is for example from the Document EP 0 843 763 B1 discloses a panel in which instead the aforementioned vertical contact surfaces inclined Contact surfaces are provided. The slopes are such that two panels, for example, by a rotation about one joint connecting around with each other can be without leaving a gap on the surface of the two Panel remains due to a game, is from this document Further, the protruding lower lip is elastic to make a connection by moving in one Level allow.

Although in the aforementioned prior art as disadvantageous felt game in the common Connection joint avoided. However, then that requires Moving a panel, which with a second to Example connected along long sides, along the common Connecting joint a great effort, usually is the Force is so great that this tool like hammer and Impact block must be used. It can Damage to the panels occur.

Due to the sloping contact surfaces as well as the elastic lip or, flank of a groove, panels can not only by moving connected to each other within a single level Way also be solved again, two can already be undesirable laid panels with appropriate force also solve each other again. This problem occurs in particular if two equal-length lips are provided and the Locking element, which the locking parallel to Floor surface and perpendicular to the joint causes located inside the groove. This is then very small to design, since there is little space available, such as Utility Model DE 29823749 U1 can be seen.

Provide two equal-length lips points to the state The technique with the long protruding lip has the following advantages on.

On the one hand, material is saved in the production and indeed in the Comparison to a prior art in which a flank or Lip protrudes from the other one groove, on the other hand the spring reaches the groove very reliably. Furthermore the consumer is very familiar with a tongue-and-groove system, where the flanks are the same length,

The object of the invention is to provide components for the Provision of a covering, in particular a panel of aforementioned type, achieved in the benefits of a panel which can be with game with a second panel can be connected without being laid disadvantageous dust and moisture undesirable in the joint can penetrate, object of the invention is also the creation a laying aid for the components according to the invention or Panels and the indication of a laying procedure.

The object of the invention is achieved by a component, in particular a Panel with the features of the first claim and by a Laying assistance and a procedure according to the siblings Claims solved, Advantageous embodiments emerge the dependent claims.

According to the invention there are between two glueless with each other locked panels a recess in which is in the final laid state is a cord or rod-like element, which in particular of a compressible material consists. As a flexible material, for example, Teflon However, it is preferable to have a material which has good elastic properties. The string or rod-like element therefore consists for example of a Rubber, silicone is preferred over rubber, however, since Silicone a suitably higher restoring force compared to rubber having. In comparison to rubber higher restoring force of Silicone has proven to be beneficial.

The provision of a gap or recess between the two Panels allow for easier sliding of a panel along a common joint even if no game should be present between two panels. The However, the presence of a game is preferable to the to ensure easy displacement. It is enough for this Purpose a game of a few 1/100 millimeters.

The aforementioned gap or recess occurs in particular at the Surface of two panels on which the visible part of a Floor or wall covering forms, From the surface Here is the cord or rod-like element visible, Im locked state is the cord or rod-like element especially so that this is the width of the gap completely fills, Advantageous is the cord or rod-like Element slightly wider. It is then in the compressed state within the gap.

By providing a gap or, a recess between the panels, in which a cord or rod-like element is located, the friction in particular compared to such Lowered panels in which the locking elements are integrally connected to the panel and from a Consist of wood material. Thus, for example, according to the invention provided integral with the panel panels be made of a wood material and yet relatively easy along a common joint also then can be moved if two panels together Are the gap with the cord or rod-like element on the visible surface, so open also as a concomitant new design possibilities. in the Joint area becomes for example black rubber or Silicone material visible. The surface of the panel can be in have a strong contrast to this. It turns out that way new optical effects, especially in laminate panels are not known, If a decent look is desired, so will the cord or bar-like element, as far as it is visible, color adapted to the visible surface, Although there are too Decors that have a colored border or colored edges the surface of each panel have, in difference For this purpose, the customer can freely choose the color of the border and also change later. So it is possible the optics of already laid panels with a relatively small effort too vary without having to remove the flooring. The at the Surface through two adjoining panels provided recess thus offers in addition to the technical Advantage of easier displacement the possibility of optical To change impressions easily.

The cord or rod-like element may be from the surface subsequently pressed into the gap or the recess or inserted. But it can already be done with one Panel be connected, especially if the cord or rod-like element consists of a compressible material, Subsequent insertion of a separate cord or rod-like Elements in a gap, however, has the advantage that the panels can be moved particularly easily, as long as that cord or rod-like element is not yet inserted.

Is a game between a protruding locking element and a corresponding recess, so can provided vertical or undercut contact surfaces become. The cord or rod-like element is then at Connect something compressed, if it is already factory with a panel was delivered, despite vertical Contact surfaces succeed in such a connection, for example, by turning around a common joint.

It is even possible undercuts in the above Locking element and the recess to be provided interconnected panels parallel to the floor surface pressed apart, so then hook in accordance with arranged locking element and accordingly arranged recess the aforementioned contact surfaces each other. A non-destructive release of the locking or, Coupling elements by moving in a plane vertical to the connecting joint is not possible. That in the state of the art called unwanted loosening due to accidental Force is avoided even if, for example a projecting flank of a groove with a Locking element is designed to be elastic at the end, So soll despite a resilient lip of a groove a particularly reliable Locking parallel to the floor surface as well as perpendicular to are created a common Verbindungsfuge, so are to prefer such contact surfaces, the undercut or are arranged at least perpendicular to the surface.

Run the contact surfaces in the aforementioned type obliquely, as is known from document EP 0 843 763 B1 a rigid configuration of a projecting lower edge or Lip of a groove to prefer, so a reliable Locking parallel and perpendicular to a common Providing joint is becoming a particularly reliable Desired connection between installed panels, so is the protruding lip even when running vertically Contact surfaces rigidly configured, allowing a release through Do not move in a plane perpendicular to the joint is possible. The other coupling elements are then, as far as necessary, rigidly formed, this is affected For example, a spring with a groove a lock effected perpendicular to the common surface of the panels.

If panels are first locked together, then it is a game exists and is provided, only then the cord or rod-like element from above into an occurring gap or Recess, so is a particularly simple Moving along a joint almost without Effort possible. The possibility of moving from already interlocked panels along one joint is particularly desirable then if two long sides of two panels are already connected and now narrow sides are still to be connected. One Such method is for example from the document EP 0855482 B1, in particular when connecting regularly requires panels along a common Move joint, despite already locked state to can, the embodiment is advantageous in which a cord or rod-like element from the top last in a gap put in or pressed into it.

The cord or rod-like element typically has one Diameter or, a width of at least 0.5 mm, preferably of at least 1 mm, more preferably of at least 2 mm on. The width does not regularly exceed 10 mm, unless a larger width is desirable for optical reasons, preferred the width is less than 5 mm, more preferably less than 3mm, Basically, however, smaller or larger widths or diameter provided for example for optical reasons be.

The gap in which the cord or rod-like element regularly has a slightly smaller width than that cord or rod-like element, especially when a game compensates or penetration of dust and moisture into one Connecting joint should be avoided. The string or rod-like element is then pressed lightly in the gap and is kept in the gap. However, the gap can be the same Have width, only a greater width of the gap in the Comparison to the width of the cord or rod-like element or to the diameter should be avoided, otherwise a unwanted gap remains on the surface and the cord or rod-like element releases too easily when released this has been inserted from the surface. An interference fit the cord or rod-like element in the gap is to be preferred because then the gap-free state is ensured and the corduroy rod-like element is held.

In one embodiment of the invention is the cord or rod-like element in the locked state between two Surfaces that cause a lock. For example, you can these are the surfaces that are called contact surfaces here. The String then consists in particular of an elastic material such as rubber or silicone, before two panels are locked the cord or rod-like element to one of the aforementioned create locked areas. The string or rod-like Element is then in particular partially in one Deepening and is pushed into this further or even completely, When panels are locked together, for example a panel by a rotary movement or a lowering movement, which is known, for example, from the publication DE 20008708 U1, in a second latched. This is the cord or rod-like Element pressed into the depression, Due to the The presence of a game can now be continued in the one panel Be pushed towards the other panel. This will the well released again. The string or rod-like Element relaxes and gets between the two (Contact) surfaces, which cause a lock.

If, for example, a projecting flank is provided, which on End through a right angle in a locking element passes, so the aforementioned depression is preferred just before the transition to the locking element, in this Well the cord or rod-like element is inserted or is already attached to the factory, for example vulcanized.

In the aforementioned embodiment it may be expedient that even in the relaxed state of the cord or rod-like Elementes a gap or a recess on the surface remains, in this gap is then a second string or introduced rod-like element, Alternatively, already at the Surface on a joint edge of a panel already a cord or rod-like element made of compressible material to be appropriate. This may be advantageous to the aforementioned To achieve design effects or to compensate for tensions that especially with a wooden material practically unavoidable are.

Is a first and a second cord or rod-like element with a joint between two panels provided so opened here also the advantage that on the surface of the Panels by means of a corresponding tool, first something can be pushed apart. It creates space, to easily insert here a cord or rod-like element to be able to. Is the cord or rod-like element largely inserted, the tool is removed. The string or rod-like element which extends between two locking Contact surfaces, then relaxes so that no Gap remains on the surface.

Is a cord or rod-like element inside the Joint provided between two contact surfaces, the cause a lock, so this allows one Embodiment in which two panels are connected by Coupling elements of a panel initially by a vertical Movement relative to the later common surface of two Panels brought into coupling elements of a second panel become. Here, the cord or rod-like element for Example be pressed into a corresponding depression. Then the panels are pushed towards each other, at a corresponding embodiment may in this Sliding a spring into a groove and so on a lock perpendicular to the common surface cause. The aforementioned cord or rod-like element finally relaxes and gets between the two locking contact surfaces.

The cord or rod-like element may be a circular or However, it is from the Surface brought in last, so it may be beneficial that the cord or rod-like element at two opposite sides hook-shaped. Will that be cord or rod-like element corresponding to a gap of Pressed on top, these hooks act like Barb, Ist the cord or rod-like element is pressed into the gap, so can the visible surface of the cord or rod-like Element surface designed to be such a flat To provide completion with the remaining surface of the panels.

Opposite to the surface of the cord or rod-like Element that is visible from the surface may have a Example arched recess may be provided so as to be inclined push the protruding hooks better into the gap.

In the embodiment with the hook and the arched lower Recess is advantageous to realize a press fit.

The cord or rod-like element advantageously comprises a Thread that practically can not be stretched. The thread becomes then wrapped in a compressible material, So Ensures that the cord or rod-like, out of one compressible material existing element through the Pressing into a gap or not into a recess Would be stretched disadvantageously, Would the cord or rod-like Element initially stretched, so it is in the laid state contract again. This would be undesirable areas at the recesses or, columns occur, not with a cord-like or rod-like element are filled.

To be particularly easy to lay, have at least two opposite sides of a panel such Locking elements on which a connection is possible, by placing one panel initially perpendicular to the other is lowered. One panel is opposite to the second one arranged in parallel. In particular, in such a case, the narrow sides equipped with such locking elements, when the surface of a panel is rectangular. The long sides are then preferably designed so that a connection in the Usually a rotary movement around a joint around Is required, a panel on the long side by a Rotary movement with the longitudinal side of a second panel connected, so can a narrow side at the same time in the corresponding locking or coupling element of a already laid panels arrive. These are also around the narrow side of the already installed panel. It may then be necessary, depending on the embodiment, the panels connected to each other over the narrow sides will be slightly overlapping, Typically, this last shift can be down to a few 1/10 Be limited in millimeters, that way that will Moving to the final position compared to the beginning mentioned prior art kept very low. Corresponding the time required for laying can be reduced, It should also be remembered that a procedure for laying the Panels that include a moving, u, a, then especially is undesirable when a panel first close to a Wall is located. A tool can barely between that Panel and wall are brought to the tool To carry out shifting, particularly unwanted one can Move further then be if a small lead to Example exists due to a door frame in a room, on which a panel should be possible to close tightly. Then it is particularly advantageous, by a lowering movement panels to connect with each other. The narrow sides can for example in the document DE 20008708 U1 be known manner, as far as the result known coupling elements on a connection by lowering Respectively.

The cord or rod-like element can be a substantially rectangular or square in diameter to to be able to effect a surface finish on the surface.

A cord or rod-like element according to the invention has the desired elasticity or flexibility when the width or, the diameter can be reduced by squeezing can, solid metal or wood is not compressible.

The claimed dimensions of the panels are advantageous Since these can be handled easily, in particular Dimensions below 100 cm advantageous, because then the panels easily transported even in the trunk of limousines can be.

Are two rod or cord-like elements provided so are These are preferably designed so that the due to the rod or cord-like elements occurring restoring forces are such that no gap remains on the surface. It is therefore advantageous that a rod or cord-like element, which to the visible surface of the panels borders, relatively small Restoring forces can cause panels are not undesirably far apart. The restoring forces can by choosing the materials that make up the rod-like or string-like ones Element to be set appropriately. Complementary or Alternatively, the cross sections can be selected appropriately. The to the surface adjacent rod or cord-like element Therefore, preferably has a larger area in cross-section than the other rod or string-like element.

In another embodiment, a cord or rod-shaped element a locking of two panels in one the said directions, so for example perpendicular to common surface of the panels, In particular, two become Panels parallel and at the same time perpendicular to the common Connecting joint locked together when the rod or cord-shaped element in a corresponding recess is pushed into it.

The embodiment in which the insertion of a rod or cord-shaped element a lock of two panels in turn, allows the presence of vertical or undercut contact surfaces, so succeeds Connection, even with unpredicted force preserved. To get vertical contact surfaces, the a lock, for example, parallel to the surface as well at the same time perpendicular to the common joint of two panels receive, the cord or rod-shaped element in The simplest case is a rectangular cross-section. The Coupling elements of the two panels that are connected should include recesses, which also have a rectangular Have cross-section. Be the two panels merged, so for example by moving in one Level, so there is finally an end position, in which the both aforementioned recesses with the rectangular Cross sections adjoin one another, they then form a channel with rectangular cross-section, in this channel is then the cord or rod-shaped element pushed in, is that cord or rod-shaped element sufficiently wide and sufficiently high, so are the two panels together locked, without a game occurs. The contact surfaces that the cause positive locking, run vertically.

In the cited prior art, in which a compound on the base of a tongue and groove connection takes place, an elastic lip or flank together with further locking elements are so to do a positive connection by moving in To allow a level can damage especially when the material is relatively rigid. This is especially the case when the coupling elements are made a wood material, such as HDF or MDF consist. This easily possible damage to the coupling elements can be avoided in the aforementioned embodiment. The Connection can be very stable mechanically, because vertical or undercut contact surfaces can be provided Even with oblique contact surfaces, like these from the Publication EP 00843763 B1 are known, a more stable mechanical connection allows, as an elastic Flank is not required and the locking element relative can protrude far.

If a protruding edge in the EP from EP 00843763 B1 known way, so this can be comparatively short, as these are not when connecting to is deflected down. It saves according to material, so there is a cost advantage here.

In the prior art, as this from the document DE 29823749 U1 is known to be two equally long flanks proposed. One of the locking serving recess is inside the groove. A corresponding one protruding locking element is at a suitable Position on the spring of a second panel. For reasons of space as well as production reasons, the locking element is only little out and has a sloping course. Corresponding the recess is shaped and dimensioned inside the groove. The resulting positive connection parallel to Floor surface and at the same time perpendicular to the joint is mechanically relatively unstable. The instability is at the This embodiment, for example, by vertical or comparatively steep contact surfaces avoided, if an embodiment with equal edges of a Coupling element acting groove is provided.

In order to undercut contact surfaces in the embodiment, in which the insertion of a rod or cord-shaped Elements causes a lock of two panels, too reach, has the rod or cord-like element in Cross-section, for example, a constriction on, recesses in coupling elements in which the rod or string-like Element is pushed in for the purpose of locking, expediently have a corresponding cross-section on.

To the rod or cord-like element in recesses at To push in coupling elements, so two To lock panels together, has the rod or cord-like element prefers a smooth surface on to Sliding friction forces occurring during insertion to keep low. The rod or string-like element exists then in particular from not or little compressible Material to make a gap on the surface of the panels too then to be able to avoid, if at the surface no additional rod or cord-like element are introduced As a material for the rod or cord-like element or its surface may therefore be appropriate Teflon, HDF, MDF also have relatively smooth surfaces and therefore can also preferably used. Also a metal rod or with a metallic surface has a smooth surface and therefore can be preferably used.

To the rod or cord-like element in recesses at Thread the coupling elements in and then push them in can, the rod or cord-like element tapers advantageous at least one end.

Preferred is the embodiment in which the pushing in a rod or cord-shaped element a lock of two panels, provided on narrow sides of panels, which have a rectangular surface. Panels will be then on the long sides, in particular by a rotary movement If necessary, become narrow sides of already laid panels then on each other geschoben, Last is the rod or cord-like element the corresponding narrow side pushed in, narrow sides, between the rod or string-shaped element in order Latch is preferable, as here the route is comparatively short. Accordingly short is the staboder cord-shaped element to push in to two panels lock accordingly.

The embodiment in which the insertion of a rod or cord-shaped element a lock of two panels can be done with a panel with those of the prior art known coupling elements for providing a glueless Combination can be combined. Especially to be preferred is one Panel with for example rectangular surface, which preferably on the longitudinal side is such that this means connected rotationally connected to a second panel without glue can be so that no play between the panels remains. Such an embodiment is known from document WO 01/48332 In particular, this embodiment comprises a rigid, projecting lower lip or flank to a mechanical stable connection to arrive at another side of the Paneels, so especially on the narrow side is then the Embodiment provided in which the insertion of a rod or cord-shaped element a lock of two First, a first and a second Panel connected by means of the rotary motion, Subsequently, the second panel along the common Connecting joint on a neighboring, already with the first Finally, the panel will be closed second and third panels finally joined together by the rod or cord-shaped element in a channel is pushed in, by recesses in the corresponding coupling elements has been formed.

According to the invention may be a parquet or Laminate panel or the like act. It can be square or be elongated. It can be made of wood, a wood material such as MDF or HDF, made of stone, plastic, clay, ceramics, metal, etc ..

So it is possible through the invention, even one made of stone laying existing floor floating.

A method for laying the covering elements or panels includes the following steps.

A first panel has already been laid. It has lower side projecting flanks on, in the leading edge is a groove-shaped recess. Either will into this recess or in a recess within the recess a string (or rod), which can be radially elastically deformed, inserted, The string or the rod preferably consists of a tendon a material with low elastic properties, that of an elastic material such as rubber is wrapped. Due to the tendon, the cord (rod) changes its length Not. A second panel is preferred with one side, and that its longitudinal side to the first example, obliquely and by pivoting in the common panel plane with the already laid panel connected so that these parallel to common surface and perpendicular to the joint joint are connected by positive locking, depending on Embodiment may also be connected by lowering the one panel over the other.

A second panel is attached to the longitudinal edge of the first laid Panels are created at an angle and by pivoting or lowering associated with this in the aforementioned manner.

The other pages, and usually the narrow sides of the Panels are designed to be locking elements grip one after the other when the one panel opposite the another is lowered. With appropriate positioning of Both last-mentioned panels are in the lowered state already a lock that the two panels parallel to common surface as well as perpendicular to the common Connecting joint locked together, then the Both last mentioned panels pushed towards each other. In this case, a spring of a panel enters the groove of a other panels. The two panels are thus also vertical to Floor level connected. if necessary The two last laid panels are in the direction of the already laid panels pushed, creating a classic tongue and groove connection is brought about. Through the classic tongue and groove connection the two panels are vertical to the common surface by positive engagement with each other locked.

The protruding lip on the narrow side also has a previously described groove on, in the collapsed Condition of the two panels can be the rod or cord-shaped Element, for example in the form of a round rubber in the channel pushed through the aforementioned groove and the last-mentioned panel is formed. The dimensions are especially chosen so that between the round rubber and a game remains the aforementioned channel. The pushing in the rod or cord-shaped element then succeeds particularly easy.

It is used a tool which essentially can be designed cuboid. By the cuboid Body passes a channel. The channel starts in particular on a front side, as these during the use of the tool typically not obscured. The canal ends at the Bottom, near the other end of the cuboid body. The channel preferably has one rectangular cross section on. The cross section is elongated. The longer sides run from bottom to top. The tool is used as a laying aid for laying the panels.

At the bottom of the tool a spring protrudes. The feather is located below the channel. The spring rejuvenates below (as seen from the tool) and / or towards the front. With "back" or "backwards" is meant in the direction of the front side, adjacent to the channel area that ends at the bottom, In one embodiment, the spring comprises a first, front lying area, which is narrower than the subsequent rear Area. The narrower area can be about twice as long as be the thicker area. The front end of the spring may be in Compared to the narrow area, continue to rejuvenate the to simplify the handling described below, namely to bring the spring of the laying aid into the gap of a joint, which by two brought together in the aforementioned manner Panels is provided. A rejuvenation to the rear Provide that the laying aid finally out again the joint can be pulled out better.

The width of the spring is initially outward and that especially down or forward so dimensioned that This can be introduced into the gap, which at the Surfaces of two joined panels at least remains. For example, the spring tapers sufficiently down, so the spring in the aforementioned gap from above coming in through lowering, rejuvenates the spring corresponding to the front, so this rejuvenation inserted into the gap and so the spring between the panels brought. The wider area of the spring is sized so that As a result, the two panels are pushed apart when the spring is inserted further between the panels. By the The cord-like or rod-like element is pushed apart compressed, which initially inserted in said groove has been.

A cord or rod-like, preferably made of silicone Element which preferably has an approximately rectangular Cross-section is introduced into the channel of the laying aid and preferably from the front side. The dimensions are like that Measure that the width of the string-like element on the Width of the channel is tuned, Further, the height of the string-like element matched to the height of the channel. It a small game remains between the string-like element and the channel.

The string-like element can easily due to the game be pushed through the tool and comes behind the spring down again to the fore. The dimensions of the rectangular cross sections are also chosen so that the cord-like element within the channel will not twist.

Is the cord-like element through the tool pushed through, so the spring is with a tapered area between the first and the second panel in brought in the gap between them. It is then, for example, at the beginning of the fugue into which the string-like element is to be brought into it.

The tool is in one embodiment of the invention with rollers provided with the help of the rollers easily along the tool Otherwise, the tool slides over the panels. There is a risk that the Surface of the panels can be damaged.

Will the laying aid along the joint, which is between the Panels is located, moved or moved and is located the spring in the gap of the joint, so the panels are first pushed apart by the wider area of the spring. In this case, the first inserted into the groove first or rod cord-shaped element which, for example, a round Cross section and consists of rubber (round rubber), pressed together. The wider area of the spring is like this dimensioned that the second cord-like element, which at the Underside of the laying aid protrudes, easily into the Connecting joint arrives. It therefore remains preferably a small Play between the string-like element and the pressed apart panels to the introduction of the cord-like element in the joint to facilitate. The string-like element thus usually comes from above coming into the joint.

If the tool continues along a joint, it closes The connecting joint behind the laying aid again a little due to the pressure applied by the first, compressed cord or rod-like element has been effected. Has the Connection fugue closed again, it will string-like element due to a suitably provided Dimensioning and / or shape by positive locking and / or Friction locked between two panels.

The tool has at the rear end in an advantageous Embodiment on a role that above the joint rolls. This will ensure that a smooth transition between the panels and the cord-like element on the Surface is reached.

In one embodiment, the laying aid is moved until the first Querfuge is reached. An eccentric element becomes laterally parallel to the transverse joint between the second and the third panel pushed. This is a gap or a channel-like recess provided in which the eccentric elongated element can be pushed into it. It is pushed in that way the narrower side of the eccentric element (eccentric) to the bordered by two panels. The dimensions are such that This can be pushed in easily. In a This embodiment can be a game between the eccentric Element and the two panels remain,

Is the eccentric element between the two panels has been pushed, so with the help of a lever movement the eccentric element rotated by about 90 °. This widens the gap of the joint, which is on the surface of the Narrow sides between the second and the third panel located. This is the rod or cord-like element compressed, which previously in the transverse joint was pushed into it.

The eccentric element may be bent at one end so that bent end into the lateral groove of one of the two Panels can be inserted, so is the 90 ° turned Otherwise, position is stable, otherwise it is different make sure the eccentric element in the twisted Position is maintained, so the eccentric element can be manually being held.

Another cord-like element, which is a preferred in has approximately rectangular cross section is coming from above pushed into the groove, located on the transverse sides between the second and the third panel is located. At the transverse sides In particular, these are the narrow sides when the Panels are rectangular, then the eccentric is back in the starting position turned back. The groove on the narrow sides Close something and the previously compressed corduroy rod-like element, which is preferably a Round rubber acts, relaxes it. The rod or cord-like element with the preferably rectangular cross-section is now in the fixed state between the second and the third panel. The fixation can by positive engagement and / or Frictional engagement has been achieved.

The eccentric is pulled out of the channel. The laying aid Continue to move until the next transverse joint is reached, up This is how the joints with string-like elements become provided that are visible from the top until the panels are complete are bordered with the cord or rod-like elements.

It has been found that by means of the invention, the panels be laid over a large area, without joints in the To provide flooring.

In one embodiment, the laying aid has a side Recess on. The laying aid will be so during installation that the recess is aligned with a groove of a transverse side, in particular a narrow side. The Recess serves to a cord or rod-like element from the transverse side can be easily inserted so that this completely up to the cord or rod-like element comes close, which brought by means of the laying aid in a joint becomes.

In a further embodiment of the invention, the spring below the Lay out the laying aid so that it spreads over its entire Length is tapered downwards so that the spring from above coming into the joint can be used. This is especially advantageous if walls the lateral access to limit to a fugue.

In one embodiment of the invention, there are in the groove, the to the Top of the two panels adjoins, a rejuvenation or stepped constriction downwards. The laying aid (the Boat) with the underlying spring is so on this groove agreed that the pressing apart of the two panels only due to a pressure is reached in the lower area, ie in the area of constriction or, rejuvenation is exercised.

Even in the compressed or relaxed state of the already inserted rod or cord-shaped element, the especially in the form of a round rubber may be located the spring of the laying aid prefers with play within the Connecting joint in the upper area, This ensures that the top of the panels no mechanical stress is exposed, especially if the laying aid off the connecting joint is pulled out. Otherwise, the Upper edge undesirable damaged and thus disrupted the look become.

In a further embodiment of the invention there is a Recess within the gap between two panels, and indeed this recess is in particular above the aforementioned taper or stepped narrowing. Becomes the cord-like element introduced into the joint, so it fills this recess out and in particular because of from the side of the cord or rod-like element protruding Noses. It then results in an improved grip of the rod or string-like element in the joint and in particular due to positive locking. The rod or cord-like element So it sits very reliable between the two Panels.

In a simplified, particularly inexpensive embodiment of the Invention, a laying aid is used, which in can be designed essentially cuboid. On one side of the cuboid body protrudes a spring. The spring is in procure the aforementioned manner. Because of this Tool manages to expand panels so that a rod or cord-like element in the joint between two Panels can be inserted without causing a frictional force too is overcome, the tool is pulled out again, so close the joints again a bit, so the staboder string-like element a hold between the two Panels. The simplified design of the laying aid can also be pushed along the joint, Behind the laying aid, the rod or cord-like element manually inserted into the widened area.

The rod or cord-like elements attached to the transverse or Narrow pages should be inserted, at least the Deckmaßlänge have the transverse joint to a closed To get surface. The deckle length can typically to be exceeded by approx. 1 mm if the transverse side is approx. 20 cm is long. Either the laying aid can be a suitable Have cutting device, in which a rod or cord-like Element inserted and exactly to the aforementioned measure can be cut, for this purpose, the laying aid For example, a channel in which the rod or string-like Element can be inserted in particular with little play. The channel is in cross section to the rod or string-like Element adapted. A cutting tool is designed so that this, for example, by pressing down the cord-like Cut the element so that it has the desired length. This Cutting tool can also be separated from the laying aid as own tools are provided.

The material of the laying aid can be a metal such as z, B, aluminum To be able to produce the laying aid cheaply, this becomes but preferably made by injection molding of plastic.

In one embodiment of the invention, the laying aid on a Upper or front side on a relatively wide role. This is preferably much wider than the rollers on the bottom, so far Rollers are present at the bottom. This role at the Oberoder End serves to conclude again on the To roll joint. If a rod or string Element a little undesirable sticking out of the joint can do so be improved. The roles in the laying aid, the serve. To exert pressure on the cord-like element around this to apply correctly into the joint preferably made of a hard material. In particular, it is a metal suitable.

The rollers on the bottom of the laying aid preferably protrude so far indicated that the distance between the bottom of the laying aid and the panels is very small. The distance can be, for example in one embodiment only a few tenths of a millimeter, so for example 2/10 mm. In this case, it is beneficial also front rollers of the laying aid, the only guide serve to manufacture from a hard material. The material should in any case be so little compressible that the distance of 1/10 up to 2/10 mm between the floor of the laying aid and the Surface of the panels is adhered to,

If square panels are used, it is not to distinguish between a longitudinal and a transverse joint. The In principle, the transfer procedure is identical. Along A joint is introduced with the help of the publisher help a rubber. Transverse joints are made using the Excenters pressed apart and a stringy element from above inserted,

In one embodiment of the invention, adhesives are provided, with which the cord-like element improves in the joint is held. The adhesive can be factory-already on the Panels have been applied. The adhesive can in a another embodiment together with the laying aid in the Fugue be introduced. The laying aid advantageously has a appropriate tank for an adhesive or adhesive on, over one suitable feed is then the adhesive in the Joint is introduced before the rubber is put into it. So it succeeds particularly well, a high quality surface which may also be relocated by a home improvement can.

On the transverse sides or, the joints that are transverse to the above Fuge can also be done with the help of a corresponding Tool or a tube, the adhesive introduced manually become.

Advantageously, panels are used in which the narrow sides be connected by lowering, first remains during the lowering a larger gap of z, B, 2,3 mm to be connected between two narrow sides of each other Panels. Only at the very end does this gap close by 0.5 mm. This associated displacement movement of a few 10th of a mm is used to press a cord-like element to bring between a joint that is at the surface Is thus provided in the like panels on the Surface, for example, remain a gap of 2.5 mm, so can here first a cord or rod-like element of 2 mm Width are inserted. Then it becomes a panel lowered over the other. The gap of originally 2 mm is reduced, so z, B, by 0.5 mm. After all, that's the case the rod-like or cord-like slightly pressed inside the joint.

The proposed coupling elements can also on the Long sides are used. In the same way, here is the Rubber be attached.

The material of the panels can be almost arbitrary. In the area Laminate flooring today consists of HDF or MDF.

However, it is not a problem, the fasteners also at Use ceramic or stone tiles.

In the following the invention with reference to embodiments explained in more detail.

Figure 1 shows two interconnected panels 1 and 2. It These are in particular panels for one Laminate flooring. The panels shown are in the example 8th mm thick. The panel 1 has a 2.5 mm deep groove on the side, the 1.9 mm wide. This groove 3 comprises an upper flank 4 and a lower flank 5. The upper flank 4 is 2.8 mm thick. The lower one Edge 5 is longer than the upper edge 4. Out of range the actual groove 3, ie in the region of the lower edge 5, the protrudes from the upper edge 4, there is a Recess 6. The recess 6 is inclined by a extending boundary wall 7 and a vertically extending Boundary wall 8 is formed. The sloping wall opens in the direction of the floor surface 9 funnel-shaped. With the Vertical to the floor surface becomes a 15 degree angle in the included in this case. The sloping wall 7 serves the transition from the actual area of the groove 3 to Recess 6. The perpendicular to the floor surface 9 extending wall 8 forms a wall of the locking element 10. The locking element 10 is located at the open end the protruding flank or lip 5 of the panel 1 Locking element 10 is opposite in the present case the bottom of the recess 6 by 0.7 mm. The wall 8 forms a contact or locking surface for locking the panels 1 and 2 parallel to the floor surface 9 as well contributes perpendicular to the joint 11.

The panel 2 has laterally a spring 12, In connected Condition of the two panels, the spring 12 is in the groove 3. The thickness of the spring 12 is adapted to the width of the groove, that there is no play up and down. The open end of the spring 12 has an oblique on the lower side extending boundary 13. There remains a gap to the here adjacent flank 5 of the groove 3. The oblique Limit 13 causes the spring 12 easily in the groove. 3 can be threaded. In particular, the recess 13 suitable to the spring 12 by means of a rotational movement about the Connecting joint 11 around in the groove 3 introduce.

Below the spring 12 a protruding nose 14 is provided, As a result, a recess 15 is formed by milling of the underside of the panel 2 can be made. The wall 16, the transition between the recess 15 and the nose 14 forms, perpendicular to the floor surface. The wall 16 at the same time forms a locking or contact surface, which in Interaction with the limiting wall 8 the form-fitting Locking parallel to the floor surface 9 and vertical to the joint 11 causes. Since the contact surfaces or Locking surfaces 8 and 16 perpendicular to the floor surface 9, this is a particularly secure form-fitting Locking between the two panels 1 and 2 in comparison scored to the state of the art, as he, for example, from the Publication WO 97/47834 A1 is known. The form-fitting Locking due to the locking surfaces 8 and 16 is further improved by the fact that the projecting lower edge. 5 is formed sufficiently rigid. The lower edge 5 is sufficiently rigid formed when the panels 1 and 2 are not connected by sliding on one level can be. Joining by moving in a plane is also from the aforementioned publication WO 97/47834 A1 known.

To the positive locking parallel to Floor surface and perpendicular to the joint 11 To further improve, the locking surfaces 8 and 16 be undercut. It is sufficient a deviation of a few degrees opposite the vertical course. The locking surface 8 is then inclined inwards towards the recess 6, Accordingly, the locking surface 16 is inwardly in Direction of the recess 15 inclined, In the connected state then hook the locking surfaces 8 and 16 together. This embodiment is particularly advantageous when the Join by moving in one level In this case, for example, the projecting edge 5 be bent sufficiently far down, so that To enable joining by moving in a layer, To improves to ensure that when installed not one unwanted release by sliding apart in one plane occurs, the aforementioned hooking is the Locking surfaces 8 and 16 particularly advantageous. By the Hooking into one another prevents, for example, the lower one Flank 5 can bend away due to shocks.

The projecting below the spring nose 14 is the open End of the spring through a sloping wall 17th limited. In the locked state, the limiting wall runs 17 parallel to the wall 7, in the locked state, as shown in the figure 1, a clearance remains between the wall 17 and the Wall 7. This can be a few tenths of a millimeter. in the In this case, it is for example 0.5 mm.

Does the locking surface 8 contact the locking surface 16, so occurs the aforementioned game of 0.5 mm between the delimiting wall 17 and the delimiting wall 7. At the same time remains on the surface of the floor, a gap, the for example 2.5 mm thick. It remains between the panels 1 and 2 in the locked state so first a game. This makes it possible to connect the panels together, although the Locking surfaces 8 and 16 in the present example vertically or at least almost vertical, even one Undercut is possible. The game is then typically 2/10 millimeters and more. How big the game should be appropriate depends in particular on the shape and dimension of the contact surfaces 8 and 16 from. A specialist will determine in each case by a few experiments, such as at least the game should at least be to connect even at steep, vertical or undercut extending contact surfaces. 8 and 16 to enable. For that reason it can too be expedient, a much larger game of for example 1 mm to provide.

In the locked state, panel 1 opposite panel 2 be moved along the connecting joint 11. This can When laying, be desired to panels in the final Position. Compared to the state of the art, like him For example, from the publication WO97 / 47834 A1, Moving is particularly easy.

To avoid getting in the gap moisture and dust penetrates on the surface 9 of the two panels at the Verbindungsfuge 11 remains, is or will be a cord or rod-like element 18 introduced. The string or rod-like Element 18 in the present case has a rectangular Cross-section and thus corresponds substantially to the shape of the Gap. The cord or rod-like element 18 thus closes flush and flat with the surface 9 of the panels 1 and 2 from.

The cord or rod-like element 18 is preferably somewhat wider as the slit in which the cord or rod-like element In the present case it is thus somewhat wider than 2.5 mm. The depth of the cord or rod-like element 18 corresponds to the thickness of the edge 4, in the present case that is cord or rod-like element so 2.8 mm deep and sits on the Upper side of the spring 12, This ensures that the cord or rod-like element 18 is not so deep in the gap come in that no flush finish on the surface 9 is achieved.

The cord or rod-like element 18 is in the present Case made of a silicone material. This is elastic and therefore can be compressed.

The gap into which the cord or rod-like element 18 introduced, extends downward, in the present case The extension runs funnel-shaped through the walls 19 and 20. The expansion can be minimal. Only a few tenths are enough Millimeter. Due to the expansion is achieved that the cord or rod-like element 18 in the area of Recess expands when this is slightly wider than the gap, This ensures that the cord or rod-like element 18 firmly seated in the gap. An unwanted release of the cord or rod-like element in the laid state becomes so counteracted.

The cord or rod-like element 18 can be the laying process so be introduced into the gap, but it is also possible, that a panel 1 or 2 from the manufacturer already with the cord or rod-like element 18 has been connected. by virtue of The compressibility of the material can be compared to Prior art, as he from the publication WO97 / 47834 A1 is known, yet achieve the desired effects. A comparatively easy movement along a joint joint is at interconnected Panels possible. The connection succeeds even at vertical or undercut extending contact surfaces 8 and 16.

The embodiment according to Figure 2 differs from the Embodiment, as shown in Figure 1, in particular by undercut locking or contact surfaces 8 and 16, This ensures particularly well that the panel 2 from the panel 1 can not be solved when the panel 2 in Direction of the arrow 21 is pulled, in particular at a elastic edge 5, this embodiment is particularly advantageous.

The embodiment according to Figure 3 differs from the Embodiments according to Figure 1 and Figure 2 by providing another cord or rod-like element 22, which between the locking surfaces 8 and 16 is introduced. This will cause the game between the panels relatively large in relation to the embodiments according to the Figures 1 and 2 may be, without the cord or rod-like Enlarge element 18 on the surface 9 of the panels 1 and 2 to have to. In addition, the cord or rod-like element 22 to compensate for shrinkage effects that occur in particular can, if the panels are made of a wood material.

If panels with a rectangular surface are used, then is the embodiment of Figure 3 on the narrow sides to prefer, since here shrinkage effects are particularly strong can make noticeable. On the long sides is the impact of shrinking effects less.

If panels are made of a wooden material, they will shrink regularly in warm temperatures. Become a panel Wood material exposed to damp areas, so they stretch regularly out. The embodiment according to FIG. 3 therefore becomes preferably provided in rooms that are heated regularly. To name here, for example, a living room one Family house.

The cord or rod-like element 22, which is between the contact or locking surfaces 8 and 16 is located, points in the cross section regularly smaller dimensions compared to the cord or rod-like element 18, which on the Surface 9 of the floor adjacent, in the present case is the Cross-section of the cord or rod-like element 22 approximately square shaped. The square is about 1 mm × 1 mm large.

In the embodiment according to FIG. 4, the recess 6 a further recess or recess 23. The recess 23 adjoins the locking surface 8, located in the recess 23 when laying a cord or rod-like element 22, Im uncompressed state protrudes the cord or rod-like Element 22 partially out of the further recess 23 out. Becomes Panel 2 connected to the panel 1, so presses the nose 14th First, the cord or rod-like element 22 completely in the Well 23 in, as indicated in Figure 4.

If panel 2 is subsequently moved in the direction of panel 1, then relaxes the cord or rod-like element 22 and passes between the locking surfaces 8 and 16. This State is illustrated in FIG. In itself that would have pressed together element elliptical have to. For the sake of clarity, the presentation differs from the Reality off.

In the embodiment according to FIG. 4, the length of the nose is 12 so dimensioned that the panel 2 by a vertical lowering opposite the panel 1 in the position shown in Figure 4 can be brought. The lowering movement is indicated by the arrow 24 indicated. Subsequently, panel 2 along the arrow 25th pushed in the direction of the panel 1. The way to that Panel 2 is moved, is very small and can be down to a few 1/10 millimeters limit, If the displacement is very short, so The times required for laying can be adjusted accordingly be reduced. This is in particular compared with the beginning mentioned prior art, the case, for example, compared the prior art, as he from the publication WO7 / 47834 A1 is known.

An embodiment in which in a first step vertical lowering along the arrow 24 is possible is preferred on narrow sides of a panel with rectangular Surface used, on the long sides is then such Connection type preferred in which the connection by a Rotary movement around the joint 11 around succeeds. One Such prior art, in which the connecting by a Rotary movement is effected, for example, goes from the WO01 / 48332 A1 or from the document US 4,426,820 out.

Panel 2 is along the arrow 25 in the direction of the panel. 1 has been pushed, then the situation shown in Figure 5 reached. In the connecting joint 11 is now still a cord or introduced rod-like element 18 (finally) and the Connect is complete. It may suffice, panel 2 only by one to two millimeters to move from the situation to get to the situation according to Figure 5 according to FIG. These Track is still relatively short compared to the tracks, in the prior art, as he for example from the Document EP 00843763 B1 is known are required.

In the figure 6 it is indicated that the panel shown in Figure 2 by a rotational movement about the connecting joint 11 with around the panel 1 is locked. In this case, the spring 12th relatively long compared to the embodiment of Figure 5 be, so that a connection is no longer possible, which initially comprises a lowering movement according to arrow 24 (FIG. 4), Then a relatively stable positive connection becomes vertical reached to the floor surface in comparison to Figure 4.

The cord or rod-like element 22 may have a circular Have cross-section. The diameter is for example approx. 2 mm. The recess 23, in which the cord or rod-like Element 22 partially located typically has one comparable width, in the example case the width would be 2 mm. The depth can be half that size. She would then 1 mm.

Does a panel include two cord or rod-like elements in the aforementioned manner, so may a cord or rod-like element 18 are very easily introduced from the surface, by first using an appropriate tool of Gap at the surface against the elastic properties of the cord or rod-like element 22 is pressed apart, In the pressed-apart state is then the width of the gap on the surface in particular wider than the width of the cord or rod-like element 18, which in the gap to be brought in. The cord or rod-like element 18 can then be inserted particularly easily. Subsequently the tool is removed and panel 1 on the panel 2 due to the expansion of the cord or bar-like element 22 introduced. This move due to the expansion of the cord or rod-like element 22 stops as soon as Equilibrium is reached. There then remains no gap at the Surface.

The cord or rod-like element 18 on the surface 9 then protects against the ingress of dust and moisture.

In the figure 7, an advantageous embodiment of a cord or rod-like element 18, which is of the Surface is introduced ago, in cross section, this cord or rod-like element 18 on both sides of a kind Barbs 26 and 27 on, around the cord or rod-like Element 18 is particularly good at squeezing the side is a curved recess 28 provided on the underside, Further, the cord or rod-like member 18 may, for example have inside a thread 29 to stretch effects too avoid. The thread 29 is therefore not one stretchable material, the according to Figure 7 of a compressible material such as silicone is wrapped.

The visible in the inserted state surface 30 of the cord or rod-like element 18 may be configured flat to achieve a flat conclusion with the panel surface 9 can.

Figure 8 shows two panels 1 and 2, in which the spring 12 of the Panel 2 has been pushed into the groove 3 of the panel 1. The projecting flank 5 has an in section at the top rectangular recess 30 on. The spring 12 has at the Bottom of a rectangular in section recess 31. The both recesses 30 and 31 are the same width, you are over each other when the spring 12 of the panel 2 in the groove. 3 of the panel 1 has been pushed completely, so that at the joint joint 11 no gap remains. The Recesses 30 and 31 form a channel into which a staboder the cord-like element is pushed in to panel 1 with panel 2 parallel to the surface 9 and perpendicular to Connecting joint 11 to lock. Moving panel 2 in Direction panel 1 succeeds up to the position shown in Figure 8 easy, because no protruding locking element overcome In the state shown in Figure 8, it is also possible very easy to move a panel 2 relative to the panel. 1 along the joint joint, as the panels are locked only perpendicular to the surface 9.

Figure 9 differs from Figure 8 by a rod-like Element 32, which in the through the recesses 30 and 31 finally, the channel formed is pushed in. The rod-like element 32 is at least almost as wide as the width of the Recesses 30 and 31, so that at the surface 9 no gap occurs at the joint 11. The material from which the rod or cord-like element 32 is, then exists preferably of a little or incompressible material, so as to create a gap at the surface 9 in the Connecting joint 11 to avoid metal or a wood material can therefore be used as a material.

Form the panels 1 and 2 in the one shown in Figures 8 and 9 Way a closed surface, so it is for example optical reasons appropriate, also on the other pages provide such coupling elements that a closed Surface is formed, in particular, it is appropriate, then Narrow sides of a panel with a rectangular surface like this train that the final locking by the Insertion of a rod 32 takes place. On the long sides are then to prefer such coupling elements, in which the Connecting by means of a rotary movement about a connecting joint he follows. This also leaves no gap at the Surface 9 between two panels 1 and 2. The joint 11 is so closed. This embodiment is shown in FIG. The Contact surfaces 8 and 16 are inclined to connect by means of a rotary motion despite a missing game too enable. The projecting flank 5 is preferably rigid form a stable locking of the panels 1 and 2 in the to ensure the laid condition.

Are the panels 1 and 2 in a to the figures 8 and 9 alternative embodiment such that at the Surface 9 remains at the joint 11 a gap, so is in this expedient a rod or cord-like element 18th introduced, which consists for example of silicone or rubber, Suitably, the rod or cord-like element 32 is made Teflon or a material with comparable flexibility and smooth surface. Then you can push in the rododer cord-like element 32 in through the recesses 30 and 31 formed channel relatively easily and indeed especially when the narrow sides of a panel so are designed. On the narrow sides occur in comparison to the Long sides namely lower friction forces, the one Slide in counteract.

The rod-like element may be shaped differently in cross-section, So this can be constricted. The cross sections of the Recesses 30 and 31 are then appropriate correspondingly shaped, so that undercut contact surfaces 8 and 33 and 34 and 35 are present, Figure 11 illustrates the Embodiment.

Do not pay attention to a special position when pushing to have, the rod-shaped element has a circular Cross-section on. Correspondingly semicircular are the Recesses 30 and 31 formed, as shown in Figure 12.

The insertion of the rod 32 is particularly easy when At least one side tapers, Preferably then run both Page pointed to, so the user or, consumers do not care It needs to be noted with which end the rod enters the canal should be threaded.

In Figure 11, the case is shown that the recesses 30 and 31 taper towards the opening. The associated rod-shaped Element 32 has a constriction. It results undercut contact surfaces. This embodiment is then particularly advantageous if the flanks 4 and 5 of the groove 3 equal are long, because then they are relatively thin and therefore relatively are flexible.

FIG. 12 shows an embodiment in which the Locking element 36 of the panel 2 by vertical Lowering be brought into the recess of the panel 1 can. The two locking elements 36 and 37 have semi-circular recesses 30 and 31, in the purpose final locking a round rod 32 pushed At the connecting joint 11, no gap or clearance remains. It is sufficient for connecting a vertical lowering of panel. 2 opposite panel 1, without having to move the panels afterwards Need to become.

If not on all sides of a panel Connecting elements are provided according to Figure 12, it is again particularly advantageous, in a panel with rectangular Surface on the longitudinal sides to provide an embodiment, when joining by a rotary motion around a Connecting joint 11 is done, by way of example, the figure 10 referenced, showing such coupling elements, to the Narrow sides is then an embodiment according to FIG. 12 Is provided, such a panel with another to the Long sides by a rotary motion around the common Connected joint, so it can be at the same time with a adjacent, already laid panel over narrow sides be connected without this panel final in the final position must be postponed, to definitive Lock is then only a rod 32 in the channel pushed, which is formed by the recesses 30 and 32.

The shape of the recesses 30, 31 and 37 and the Locking element 37 may be of the type shown in FIG Deviate embodiment. It just depends on that the shapes are such that, finally, the desired glueless Locking in the directions mentioned is possible.

By the invention succeeds, the following method for the To provide connection of two panels. A panel 1 is with a panel 2 brought together so that recesses 30 and 31 form a channel. The coupling elements are like this then procure that the panels in a first direction are locked. In the channel is then a rod-shaped Element pushed into it. The coupling elements are like this procure that then the two panels both perpendicular to common surface 9 as well as parallel to the common Surface 9 and at the same time perpendicular to the connecting joint 11th are locked.

The element 32 may also be made of an elastic material preferably high restoring force exist. It can then be in one the two recesses 30 or 31 already attached to the factory have been. The cord-like element then exists in particular made of silicone or a hard PVC.

A rod or cord-like element according to the invention lies especially if the diameter is at least 0.5 mm, preferably at least 1 mm. Indicates the rod or cord-like element has a rectangular cross-section on it, so be length and width of the rectangle preferably at least 0.5 mm, more preferably at least 1 mm. A bar or cord-like element according to the invention is in particular Furthermore, if it is an independent part, which as be glued in one embodiment with a panel can. The physical properties do not change Then, such a rod or cord-like element is in one Embodiment to be distinguished from the case in which a Paste or similar on a panel in a flowable state is applied and then solidifies the paste.

FIGS. 13 and 14 show embodiments which are a Further development of the shown in Figures 4 and 5 Represent embodiments.

In the figure 13, the coupling elements on the longitudinal side an already laid panel 1 shown in section. The panel 1 has laterally on the longitudinal side a lower projecting edge. 5 on. In the above edge 5 is a groove-shaped Recess 6 with a groove-shaped recess 23, In the Recess 23 within the recess is a cord 22nd been inserted. The cord comprises a string or, thread 29 made of a material with low elastic properties, the Covered by a rubber or silicone, Due to the tendon the cord 22 does not change its length. A second panel 2 was obliquely applied with its long side to the first panel 1 and by pivoting in the common panel plane. 9 This brought the panel 2 with the already laid Panel 1 connected so that these are parallel to the common Surface 9 and perpendicular to the common joint 11 through Positive locking are interconnected.

The spring 12 of the panel 2 is just in the present case short enough to lower the panel 2 by lowering it with the panel 1 in connect the aforementioned manner. After lowering would have Panel 2 are pushed in the direction of the panel 1 to get to the situation shown in Figure 13. The Spring 12 could have been longer, as a connecting through oblique application and subsequent pivoting to the Long sides is basically unproblematic.

A second panel 2a was attached to the longitudinal edge of the first laid panels 1 inclined and by pivoting with connected in the aforementioned manner.

The narrow sides of the panels 2 and 2a shown in FIG. 14 are such that locking elements 14 and 10 engage one behind the other when the one panel 2a opposite to the other panel 2 is lowered suitable. With appropriate Positioning of the two last-mentioned panels 2 and 2a are it already has a latch after lowering the panel 2a, the two panels 2 and 2a parallel to the common Surface 9 and perpendicular to the joint joint 11 locked together, then the last two said panels 2 and 2a pushed towards each other. there the spring 12 of the panel 2a passes into the groove 3 of the other Paneels 2. The two panels 2 and 2a are thus also vertical connected to the floor level, as in the figure 14th will be shown. If necessary, the two last laid panels 2 and 2a in the direction of already laid Sliding panels 1, creating a classic tongue and groove connection also between the panel 1 and the panels 2 or, respectively, 2a is created. Through the classic tongue and groove connection Both panels 1 and 2 and 1 and 2a are vertical to common surface 9 by positive engagement with each other locked.

The protruding lip 5 on the narrow side of the panel 2 has also the previously described groove 6 with a recess 23 on. The recess 23 is adjacent to the upwardly projecting Locking element 10, which at the open end of protruding lip or flank 5 is located. in the collapsed state of the two panels 2 and 2a becomes the cord-shaped element 22, which in the figure 14 a has a circular cross-section, pushed into the channel, the through the aforementioned recess 23 and the above formed area of the last-mentioned panel 2a formed becomes. The locking element 14 of the panel 2a, which is extends downwards, contributes to the provision of the channel into which the cord-shaped element 22 - as shown in Figure 14 in section - has been pushed into it. The dimensions can be chosen like this be that between the cord-shaped element 22 and the aforementioned channel remains a game. The insertion of the cord-shaped element 22 then succeeds particularly simple.

It is now in the figure 15a in a side view and in the FIG. 15b shows a tool 40 shown in a front view. The main body 41 is designed substantially cuboid, Through the cuboid body 41, a channel 42 passes, The channel 42 begins at a front side 43 (front), since this Front side during use of the tool 40 typically is not obscured. It ends at the bottom 44 and although close the other end face 45 (rear) of the cuboid body 41st The channel 42 has a rectangular cross-section, as in the Figure 15 b can be seen. He prefers to expand, for example towards the front side 43 out to the insertion of a cord-shaped element 18 to simplify. The longer sides 45 a of the rectangular cross-section are parallel to the Side walls of the tool 40, ie from bottom to top. The Dimensions of the cross section of the channel 42 are so on the cord-shaped element 18 adapted that this within of the channel 42 will not twist. So is shown in the Embodiment is practically impossible due to the adaptation the cord-shaped element 18 is rotated by 90 ° in the channel 42nd introduce.

The tool 40 is used as a laying aid for laying the panels 1, 2, 2a used. With the support of the laying assistance this will be cord-like element 18 brought into the joint 11, which through the Panels 1 and 2 is formed.

At the bottom 44 of the tool 40 protrudes a spring 46, The spring 46 is disposed below the channel 42. The spring 46 tapers downwards (as seen from tool 41) as in FIG. 15b becomes clear.

In one embodiment, the spring 46 includes a first, forward lying area 47, which is narrower than the subsequent rear area 48. The narrower area 47 is - as shown in FIG 15a - preferably longer, so for example about twice as long as the thicker area 48 to handle easy to design. The front end 49 of the spring 46 may be in comparison to the narrow region 47, continue to rejuvenate the To bring the spring of the laying aid in the gap of a joint 11, the due to two brought together in the aforementioned manner Panels 1, 2 is present. A taper 50 of the spring 46 to the rear Provide improved ensures that the laying aid 41st finally pulled out of the gap 11, in particular without damage to the panels 1, 2 too cause.

The width of the spring 46 is initially toward the outside and indeed especially down or forward so dimensioned that this can be inserted into the gap of the joint 11, attached to the Surfaces of two joined panels 1, 2 at least, the spring 46 tapers, for example sufficiently downwards, so the spring 46 in the aforementioned gap 11 coming from above by lowering The spring 46 tapers towards the front, so this taper can be 47, 49 introduced into the gap 11 and so the spring 46 is placed between the panels 1, 2, The wider portion 48 of the spring 46 is sized so that As a result, the two panels 1 and 2 pressed apart be when the spring 46 further between the panels 1 and 2 is inserted and so the wider area 48 suitably between the panels 1 and 2 passes. By breaking apart is the cord-like element 22 is compressed, which initially in the recess 23 of the present in the form of a groove Recess 6 of the panel 1 has been inserted.

A cord or rod-like, preferably made of silicone Element 18, which preferably has an approximate rectangular or at least elongated cross-section is introduced into the channel 42 of the laying aid 41 and although preferred from the front side 43 ago. The dimensions are such that the width of the cord-like element 18 to the width of the channel 42 is coordinated. Further, the height of the string-like element 18 matched to the height of the channel 42. There remains a game between the cord-like element 18 and the channel 42, so that the cord-like element passes through the channel 42 can be pushed

The cord-like element 18 may due to the game through the Tool can be pushed through and comes behind the spring 46 near the rear end wall 45 at the bottom 44 again to the fore. The dimensions of roughly rectangular Cross sections are chosen so that the cord-like element 18 within the channel 42 will not twist when passing through the channel 42 is pushed or pulled through,

Is the cord-like element 18 through the tool 40th pushed through, so the spring 46 with a tapered area between the first panel 1 and the second Panel 2 brought into the gap 11 between them, The laying aid 40 is then in particular at the beginning a joint 11 into which the cord-like element has been inserted shall be.

The laying aid or, the tool 40 is in one embodiment the invention provided with rollers 51 and 52, with the aid of Rolls 51, 52 easily the tool 40 along the Otherwise, the tool slides 40 over the panels 1 and 2. There is a risk that the surface of the panels 1 and 2 can be damaged.

Will the laying aid 40 along the joint 11, which is between the panels 1 and 2 is located, moved or moved and is the spring 46 in the gap of the joint 11, so The panels 1 and 2 are first through the wider area 48 of the spring 46 pressed apart. This is the beginning in the groove or the recess 23 inserted first cord-shaped Element 22 compressed. The wider area 48 of the spring 46 is dimensioned such that the second cord-like element 18, which protrudes on the underside 44 of the laying aid 40, is easily pressed into the joint 11. The Dimensions are preferably sized so that there is a small Play between the string-like element 18 and the pressed apart panels 1 and 2 remains to the Introduction of the string-like element 18 in the joint 11 to facilitate. The cord-like element 18 thus arrives in the Usually coming from above into the joint 11 into it.

If the tool 41 continues to move along a joint 11, then closes the connecting joint 11 behind the laying aid 40th again a little bit due to the pressure of the first, compressed, cord-like element 22 has been effected. Has the connecting joint 11 closed again something, it will be cord-like element 18 due to a suitably provided Dimensioning and / or shape by positive locking and / or Friction locked between two panels 1 and 2.

The tool 40 has at the rear end near the end wall 45 in an advantageous embodiment, a roller 51, the rolls above the connecting joint, this ensures that a smooth transition between the panels 1 and 2 and the cord-like element 18 is reached at the surface, This case is not shown in FIGS. 15 a and 15 b.

In one embodiment, the laying aid 40 is moved until a first transverse joint 60 is reached, as shown in FIG. 16 Showing a supervision on panels 1, 2, 2a, Behind the Laying aid 40 is then already a cord-like element 18 in the Fugue 11 entered.

An eccentric element 70 which is shown in section in FIG. 19 is shown laterally parallel to the transverse joint 60 between the second panel 2 and the third panel 2a pushed. This is a Gap or preferably a channel-like recess 71 (as shown in FIG. 17) at the panel 2 and / or at the panel 2a, into the eccentric elongate member 70 can be pushed into it. The eccentric element 70 becomes so pushed in that the narrower side of the eccentric Element (eccentric) adjacent to the two panels 2 and 2a. The Dimensions are sized so that this easily can be pushed into it. In one embodiment, the Support a game between the eccentric element 70 and the two panels 2 and 2a remain.

Is the eccentric element 70 between the two panels has been pushed, so is using a in the figure 19 shown lever 73, the eccentric element 70 by ca, 90 ° twisted, as indicated by the arrow 72 in Figure 17. As a result, the gap 60 shown in FIG on the surface at the transverse sides between the second Panel 2 and the third panel 2a is, As a result of 90 ° rotation the cord-like element 22 is compressed, which previously in the designated channel within the Querfuge 60 was pushed into it. The rotated by 90 ° position of the eccentric element is shown in FIG.

The eccentric member 70 may at the end of the lever 73 so Be bent that bent end 74 into the lateral groove one of the two panels 2 or 2a can be introduced, So becomes the 90 ° rotated position of the eccentric member 70th Otherwise, otherwise ensure that held the eccentric member 70 in the rotated position becomes.

To the introduction of the eccentric element 70 in the for provided channel 71 or a sufficiently wide gap facilitate, this preferably has a taper 75. This tapered area is first in the designated channel 71st or the sufficiently wide gap provided for this purpose.

Another cord-like element 18, which has a preferred in approximately rectangular or elongated cross-section, can of Coming up in the gap are pushed in, the on the transverse side 60 between the second panel 2 and the third Panel 2a is located. It may alternatively be from the side pushed in, especially the dimensions in this position are sized so that the cord-like element 18 with play is located in the joint, as illustrated in Figure 18.

The transverse side 60 is in particular a Narrow side, when the panels 1, 2, 2a a rectangular Have surface.

Subsequently, the eccentric 70 is returned to the starting position turned back. The groove on the transverse side 60 closes something and relaxes the previously compressed cord-like element 22 in the process. The cord-like element 18 with the preferred rectangular cross-section is now in the fixed state between the second panel 2 and the third panel 2a. The Fixation can be achieved by positive locking and / or frictional engagement According to Figure 17, the fixation is particular due to positive locking, but also due to traction reached, since then the cord-like element 18 with the preferably elongated cross-section slightly pressed in the joint located.

The eccentric 70 is then out of the channel 71 and, respectively pulled out corresponding gap. The laying aid 40 is Continue until the next transverse joint is reached Way are the joints 11, 60 (or, column) with cord-like Elements 18 are provided, which are visible from above until the Panels 1, 2, 2a completely with the cord or rod-like Elements 18 are bordered.

It has been found that by means of the invention, the panels be laid over a large area, without joints in the To provide flooring.

In one embodiment, the laying aid 40 laterally a Recess on. The laying aid 40 is during installation move so that the recess is aligned with a joint, the from a transverse side 60, in particular a narrow side, The recess serves to make a cord or rod-like Element from the transverse side 60 ago so easily be inserted This can be completely up to the cord or rod-like Element 18 comes close, which by means of the laying aid in a Fugue 11 is brought.

In a further embodiment of the invention, the spring 46th below the laying aid so that they are above their own entire length tapered downwards so that the spring of Coming up in the joint can be used. This is especially advantageous if walls the lateral access to limit to a fugue.

In one embodiment of the invention, there are in the joint 11, the the top 9 of the panels 1, 2, 2a borders, a taper or stepped constriction 76 downwards. The tool 40 with the underlying spring 46 is then so on this joint with the constriction 76 tuned that the pressing apart of the both panels 1 and 2 is reached only by pressure, in the lower area, ie in the area of the narrowing 76 or Rejuvenation is exercised.

Even in the compressed or relaxed state of the already inserted rod or cord-shaped element 22, the in particular has a circular cross section is located the spring 46 of the laying aid 40 with play within the Connecting joint 11, as far as the upper area, ie above the Narrowing 76 is affected, This ensures that the Top edge of the panels 1 and 2 no mechanical stress is exposed, in particular, when the laying aid 40th is pulled out of the joint 11, otherwise could the upper edges of the panels 1 and 2 undesirable damaged and thus the appearance are impaired.

In a further embodiment of the invention there is a Recess 77 within the joint 11 between two panels. 1 and 2, namely, this recess is in particular above the aforementioned taper or step-shaped Constriction 76, the cord-like element 18 in the Joining joint 11 introduced so it fills this recess 77th from and in particular due to the side of the cord or rod-like element 18 projecting lugs 78. It then results an improved retention of the rod or string-like element 18 in FIG the joint 11 and that because of the thus achieved positive engagement. The rod or cord-like element 18 is then sitting so special reliable between the two panels 1 and 2.

In one embodiment of the invention, the laying aid 40 indicates a top or front side of a relatively wide roller 80, the in particular wider than the wheels or rollers 51 and 52, This is thus preferably much wider than the rollers on the Bottom. This roll 80 on the top or front side serves to Finally, once again over the connecting joint 11, 60 to Roll, If a rod or string-like element 18 a little undesirably sticking out of the joint 11, 60 can do so be improved. The rollers 52 and 80 at the laying aid 40, which serves. Pressure on the cord-like element 18 to apply this in the joint 11, 60 are preferably made of a hard material, In particular, a metal is suitable.

The rollers 51, 52 preferably project at the bottom of the laying aid 40 far as apparent that the distance between the bottom of Laying aid and the panels 1, 2 is very low. The distance For example, in one embodiment only a few tenths of a millimeter, for example 2/10 mm. In this Case, it is advantageous, even front rollers 51 of the laying aid 40, which only serve to guide, made of a hard material finished. In any case, the material should be so little compressible that the distance of 1/10 to 2/10 mm between the bottom of the Laying aid 40 and the surface 9 of the panels 1, 2 gehalfen becomes.

FIG. 20 shows a further embodiment of the invention, namely Panels 2 and 2a, in which at least one side by Lowering can be interconnected, below is too understand that a panel 2a parallel to the already laid Panel 2 held and lowered for the purpose of connecting While lowering, the parallel position can be panel 2a has been lowered so far that it is in the same plane as the panel 2, so then there is a downwardly projecting nose 14 in one upwardly open recess 6, parallel to the surface 9 and perpendicular to the joint, the panels 2 and 2a are then through Locked form locked together. That at the bottom of the bottom projecting lip 5 upwardly directed locking element then something has been bent outwards, what can be favored in particular by a slope 90, the Advantageously located below the locking element.

First, remains on the surface 9 of the panels 2, 2a a Gap of for example 2.5 mm, now becomes a cord-like Element of for example 2.2 mm width in this gap put into it, this succeeds easily, as a game exists After inserting the string-like element, panel 2 is approx. 0.5 mm pushed in the direction of the panel 2, so that here relatively short spring 12 enters the groove 3 and so a Locking vertical to the surface 9 is obtained. These Displacement movement of a few 10th mm is used to the cord-like element pressed between the joint to bring, which is provided on the surface 9.

The coupling elements according to FIG. 20 can be used on all Pages are inserted. Because the latch in vertical Direction is relatively weak, this is preferable Coupling elements, a relatively short in the groove. 3 projecting spring 12 include only on transverse sides 60th use.

FIG. 21 shows an embodiment of the invention that belongs to is preferable if only a rod or cord-like element 18 brought from the top 9 ago between two panels 1 and 2 Is the string-like element not between the two Panels 1 and 2 brought in the manner shown, so are the two Panels preferably locked together so that a small Game remains.

The panels 1 and 2 shown in Figure 21 are such that at the top of the gap 11 a gap remains. The gap is prefers something less wide (a few tenths of a millimeter) than that rod or cord-like element 18. Is the rod or cord-like element pressed from above into the gap, so then this gets slightly compressed into the gap, This will ensure that the top is waterproof is closed. Moisture problems are avoided.

The gap shown in FIG. 21 is shown in FIG Embodiment up to the top of the spring 12, off For manufacturing reasons, this is appropriate, but for the execution the invention is not necessary.

To ensure a precise and reliable fit of the bar or cord-like element 18 between the panels 1 and 2 ensure this is by positive engagement in the desired Location held, In the present case there is within the gap at least one, preferably two projecting lugs 95, the side connected to the respective panel. These above Noses not only serve the aforementioned form-fit, but at the same time form a constriction in the interior of the groove. The narrowing the groove is advantageous to using a tool (laying aid) the two panels in the manner already described apart to be able to press without the edges at the surface 9 too to damage.

A rod or cord-like element 18, as in the case of FIGS shown panels 1 and 2 is used in the Figures 22 and 23 shown in section. It has at least sides a preferred two recesses 96. The recesses 96 thus cooperate with the protruding lugs 95 that As a result, the desired positive connection is achieved.

At the bottom of the rod or string-like element 18 there are preferably a groove 97. In this way, the rod or string-like Element 18 has two legs, which are slightly sufficient can be pressed together. It is then especially easy the rod or cord-like element 18 in the space provided Gap in the gap 11 to push.

At the bottom, the rod or cord-like tapers Element 18 funnel-like. By the corresponding oblique extending surface areas 98 ensures that the rod or string-like element 18 slightly into the gap can be brought into it.

The rod or cord-like element 18 shown in FIG is preferably made of a relatively hard, but still sufficiently elastic material, such as a hard one PVC material.

To be preferred is the embodiment shown in Figure 23, Here is an upper portion 99 of the rod or string-like Elements 18 made of a comparatively soft, elastic Material such as a soft PVC material, if the lower portion 100 of a relatively hard material such as rigid PVC consists. The range of harder material ensures especially good the proper reliable fit of a rod or string-like element between two panels 1 and 2. The portion consisting of a relatively soft region 99 ensures that the rod or cord-like element 18 also can be squeezed here. This ensures that the rod or string-like element 18 completely into the gap can get between two panels 1 and 2, even if this something is narrower. The upper portion 99 is then advantageous lightly pressed between the two panels to counter penetrating moisture, dust etc, to protect.
