Definitions

  • the invention relates to a panel with a user surface and with four edges, of which opposite edge pairs have corresponding retaining profiles, so that similar panels are connectable on all four edges, the retaining profiles of a first pair of edges are connected by Einwinkein, and wherein the retaining profiles of a second Edge pair are formed as complementary hook elements, so that at each of the hook elements a similar neighbor panel is connected by means of a joining movement, which takes place in a plane of movement perpendicular to the plane of the panel, with the proviso that at least one of the hook elements of the second edge pair a separate Vertical locking element is provided which protrudes at least partially into the joining path of the hook elements, wherein the vertical locking element during the joining movement of the hook elements of two panels is automatically moved out of the Fügeweg to release this, and ver State of the hook elements by spring action automatically hineinbewegbar in the Fügeweg.
  • the invention relates to a floor covering, which is composed of a plurality of inventive panels.
  • Known panels of the type mentioned are known from WO 03/016654 A1 (Akzenta) and from WO 2006/043893 A1 (Välinge). From both publications, the expert knows panels, which are laid, for example, in rows, wherein within a row panels are joined together at joints. Conveniently, the known panels are laid so that the joints of a row of panels are arranged at a distance from the impact points of the panels of an adjacent row. In In a new series a panel is connected to the previous row by so-called "in-line".
  • in-line refers to a method of joining in which a new panel with an edge is attached to the panels of the previous row, the new panel being added in an oblique plane relative to the plane of the previous row of panels.
  • the new panel is locked by an angular movement, during which the new panel is swung down to the level of the panels of the previous row.
  • the new panel will also be connected to the panel of the same row during the above-described movement of the panel on panels of a previous row.
  • the mutually associated holding profiles of the edges are formed as hook elements for the connection of the panels within a row, which can be moved towards each other in a direction perpendicular to the plane of the panels and hooked in this way.
  • the movement in said vertical plane is a scissor-like movement. It can also be called a folding movement.
  • the known panels have at least on a hook element on an automatically latching vertical locking element, which makes it difficult to separate the panels for disassembly, because the vertical locking element can not be moved or only with a special tool from its locking position.
  • the vertical locking element can be taken laterally out of the connection so that the hooked panels can then be moved apart again in a direction perpendicular to the panels.
  • WO 2006/043893 teaches, instead of the removal of the vertical locking element, to use a special tool with which the vertical locking element has to be moved out of its locking position, so that it is then possible to move the panels apart perpendicular to the plane of the panels.
  • the special tool is a kind of needle, which laterally into a gap in which the vertical locking element is inserted. It is imperative that needle-thin special tool whose top and bottom are different to move properly around in the gap by the vertical locking element is located.
  • a third method of unlocking is to move apart hook elements in the panel plane, namely parallel to the hooked edges. However, the latter method is unfavorable for such panels, between the hook elements, a high static friction prevails, and can therefore be moved only with great effort.
  • the invention has for its object to provide easy to install panels and also to simplify the disassembly of a floor covering, which is assembled from generic panels.
  • the object is achieved in that the complementary hook elements are designed so that the panels are unlocked from their hooked and vertically locked state when two panels are connected, that at least one panel in an axis extending in the region of the hooked edges in a direction is pivotable in which an unlocking position is reached and that the user surfaces of the panels in the unlocked position at an angle to each other, which is smaller than 180 °.
  • the hook elements are designed such that panels of a row of panels can then be separated if they no longer have any connection to panels of a neighboring row. If the panels of a row of panels are to be separated from one another, this row of panels must first be released from the connection with their adjacent rows of panels. Then the panels of the same row of panels can be mounted by a panel, which is only connected at one end within the row, is pivoted at this end up and the previous panel from which it is to be separated, is not moved.
  • this movement of accessing panels of the same panel row corresponds to a reversal of that movement described above as being an angle, and with which (new angle movement) a new panel is attached to panels of a previous row.
  • connection operations can influence one another.
  • an adjustment of the position of the hookable edges relative to one another takes place with the scissor-like movement (folding movement) of the new panel.
  • This then requires a sliding movement within the intertwined edges of the first edge pairs of the panels involved in order to bring the verhakbaren edges of the second pair of edges during the folding movement in the desired position.
  • the hook elements can be designed so that an automatic positioning of their edges can be effected by their shape. Then the automatic positioning is initiated by the folding movement of the new panel.
  • the panel of the invention may be formed, for example, as a floorboard, parquet or laminate panel and therefore either consist of solid wood or have a core material.
  • the core material may be a wood material consisting of grown wood parts, such as a blockboard made of rod-shaped pieces of wood, a multiplex board made of wood layers, or a plywood.
  • fiber material can also be provided as the core material.
  • wood which was first cut into pieces of fiber, and then by admixture of Binder has been processed into a wood fiber material, such as MDF, HDF, plywood or OSB board.
  • other materials for a panel according to the invention are suitable, for example, solid plastic or at least plastic as a core material.
  • the panel comprises a core material, it is coated and typically has a utility surface with decorative properties.
  • the invention is particularly useful when the panel is made of a grown fiber-free wood material, such as solid wood or a core material of a fiber-free wood material. Holding profiles, in particular hook elements made of solid wood grown or made of fiber-free wood material in the locked state because of their heatnbeschaf- fenheit high adhesion to each other and can be pushed apart. This has the consequence that the above-mentioned known from the prior art third method of unlocking for such panels is unfavorable.
  • the unlocking invention is particularly practical for panels made of solid wood or panels with a core material, which is a fiber-free wood material according to the invention.
  • the holding profiles of the first pair of edges on one edge of an undercut groove profile and on the opposite edge of a complementary spring profile which can be connected together by Einwinkein.
  • a plurality of such undercut groove and tongue profiles are known, which are connectable by Einwinkein, and are therefore suitable for the panel according to the invention.
  • the known retaining profile geometries can therefore be provided on the first edge pair and combined with the hook element according to the invention on the second edge pair.
  • the hook elements of two panels are always connectable even when two panels to be joined lie in a common plane.
  • To the hook element of a panel is placed in alignment behind the hook element of a neighboring panel, so that the cross sections of the hook elements lie exactly in line with one another. Then, the edges provided with the hook elements are pushed into each other until they overlap on the desired length of the panels.
  • FIG. 44 in DE 10 2006 011 887 which illustrates this with an example.
  • the edge 32 of a panel 30b is flush-fitted in the direction of the arrow with an edge of a panel 30a. It may be necessary at the beginning of the aligned movement to press the elastic vertical locking element projecting from the edge a little and to set it so that it fits into the neighboring panel.
  • An alternative embodiment of the panel provides that the retaining profiles of the first pair of edges instead of the above-described modified tongue and groove profiles are designed as complementary hook elements that at least one of the hook elements of the first pair of edges a separate vertical locking element is provided that the vertical locking element after Type of flexible spring protrudes from the edge of the panel that the complementary hook member has a groove formed as a detent recess, and that at least a part of the protruding flexible spring of the vertical locking element in the groove of the complementary hook member is angled.
  • any panel and vertical locking member of the present invention can be used to conform the retaining profiles of the first pair of edges and to the panel in panels to use a previous row.
  • the decisive for the connection of the panel edge projecting portion of the vertical locking element is to be understood in the context in the broadest sense as a flexible spring.
  • This part of the vertical element can have a cross-section sen, which comes close to that of a conventional spring or far from it.
  • Decisive for the vertical locking element with its flexible spring is its blocking function in the direction perpendicular to the panel plane and its suitability for a Einwinkein of panels.
  • At least one of the edge pairs is provided with corresponding hook elements, of which each hook element has at least one undercut surface, that the undercut surfaces of the two hook elements are arranged so that they are arranged in the hooked state of two panels on a common Entriegelungskurve and in contact , and that the undercut surfaces on the common unlocking curve are away from each other and toward each other.
  • the handling of the panels can be improved if a hook element can be positioned for connection to the complementary hook element of a neighboring panel on a substrate, wherein the joining of the hook elements of two panels is effected by the fact that the panel can be positioned on the ground and rests with the neighboring panel a joining movement is feasible, and wherein the vertical locking element is preferably provided on that hook element which is located on the edge of the stationary panel.
  • the hook elements can be caught more sensitively for the user when the vertical locking element is arranged on the lower, resting panel. This also has the advantage that the vertical locking element, when placed on the lower panel, is more visible to the user. It therefore helps when the movement of the vertical locking element caused by the user-induced joining movement the hook elements is initiated, for the user is also recognizable.
  • the vertical locking element can be moved elastically.
  • the elastic movability can be produced by elastic properties of the vertical locking element itself or by a separate spring element which cooperates with the vertical locking element.
  • At least for the elastic mobility of a vertical locking element may be provided a plane of movement which is arranged parallel to the plane of the panel.
  • a vertical locking element which is arranged in a plane of movement parallel to the plane of the panel, usually has no constant spring properties over its entire length. However, arranged parallel to the plane of the panel vertical locking element usually has good strength properties in a vertical stress of a compound provided therewith. This is because the vertical locking element can be provided with a relatively large cross section.
  • a plane of movement is provided which is arranged both perpendicular to the plane of the panel and perpendicular to the edge provided with the vertical locking element.
  • the resiliently movable part of the vertical locking element in this case, because it is to be accommodated in a plane perpendicular to the panel, must be formed with a relatively small cross-section.

  • a panel proves to be particularly advantageous if a core material made of HDF (high density fiberboard) or MDF (medium density fiberboard) is provided. These core materials are made from crushed pieces of wood with the addition of a binding agent. They can be machined very well and have sufficient strength properties to attach retaining profiles according to the invention and to add separate vertical locking element. As mentioned above, however, the panel can also be made of other materials.

Abstract

L'invention concerne un panneau avec une surface utile (N) et quatre bords, dont les paires de bords opposés présentent des profilés de fixation correspondants, afin que des panneaux similaires puissent être raccordés aux quatre bords. Les profilés de fixation d'une première paire de bords peuvent être raccordés par équerrage, et les profilés de fixation d'une seconde paire de bords peuvent être conçus en tant qu'éléments d'accrochage (6a, 7a) complémentaires, de sorte qu'un panneau voisin (6, 7) similaire puisse être raccordé à chacun des éléments d'accrochage (6a, 7a) par un mouvement d'assemblage dont le plan est perpendiculaire au plan du panneau, sous réserve qu'un élément de blocage vertical (8) séparé faisant saillie dans la trajectoire d'assemblage des éléments d'accrochage (6a, 7a) soit prévu au moins sur l'un des éléments d'accrochage (6a, 7a) de la seconde paire de bords. L'élément de blocage vertical (8) peut sortir automatiquement de la trajectoire d'assemblage pendant le mouvement d'assemblage des éléments d'accrochage (6a, 7a) de deux panneaux (6, 7), afin de libérer celle-ci, et peut se déplacer à nouveau automatiquement dans la trajectoire d'assemblage (M) par effet ressort, les éléments d'accrochage (6a, 7a) étant accrochés. L'invention vise à simplifier le démontage. A cet effet, les éléments d'accrochage (6a, 7a) complémentaires sont conçus de telle sorte que les panneaux (6, 7) raccordés puissent être désengagés de leur état accroché et bloqué verticalement, qu'au moins un panneau (6, 7) puisse pivoter autour d'un axe s'étendant dans la zone des bords accrochés dans une direction, dans laquelle une position de désengagement peut être atteinte, et que les surfaces utiles (N) des panneaux (6, 7) dans la position de désengagement forment les unes avec les autres un angle inférieur à 180 degrés.
