Description

The invention relates to a drive rail for the automation of a garage door with a substantially rectangular cross section, wherein within the drive rail, an endless power transmission means rotates, which is driven by a motor. With the power transmission means within the drive rail translationally variable carriage is connected, which is articulated by means of a protruding from the drive rail drive arm to the gate. Furthermore, the invention relates to a method for mounting two drive rail sections with each other.

By the DE 20 2011 107 685 U1 is a drive rail has become known, which has a rectangular cross section with open at the bottom passage. Such a drive rail is fastened by lateral supports on a ceiling. At the free end of the drive rail, a drive device is arranged, which drives an existing within the drive rail power transmission means in conjunction with a carriage for opening the door.

The attachment of a drive rail below a ceiling can be realized by punches or connection bracket, which are attached to the drive rail. Such a fastening is the DE 41 18 782 A2 and the DE 91 12 357 U1 refer to.

Another way of fastening the drive rail is the EP 1 398 448 A2 again. In this case, from a ceiling of the building reaching angles are used with the aid of a transverse angle and lateral claws Service. The claws engage within the drive rail in lateral grooves.

The DE 85 36 639 U1 shows an electromechanical garage door drive with a guide rail in which a carriage body is movable in the longitudinal direction. The guide rail is substantially C-shaped. Connected to the carriage body is an angle geared motor located within the guide rail and connected to the carriage body through a bottom opening of the guide rail. The opening of the guide rail to the bottom side is formed very wide, so that a person can engage in the drive rail, which can lead to injury in the case of a movable carriage body.

Further, a running rail for a roller-guided driver of a door leaf having a substantially C-shaped cross-section of DE 93 19 898 U1 refer to. In an analogous manner, such a guide rail is also in the DE 20 2005 016 816 U1 described. Also in this cited prior art, a large, directed to the ground opening area in the guide rails is present, which allows a human intervention.

A cable guide for receiving at least one cable, consisting of a substantially U-shaped bracket having at least one guide channel for receiving the cable and is placed above a drive rail of a garage door drive as an additional component, are the DE 20 2005 019 968 U1 again.

The DE 298 10 158 U1 discloses a guide rail in a C-shaped embodiment for garage door operators, in which the guide rail consists of several segments and is interconnected by connecting elements.

With the DE 10 2007 062 466 B3 is a connection element for rails of a hanging track known. In this case, a securing device for securing the running rail against pulling out of a cavity, and a running rail system with a plurality of connectable by connecting rails. In this case, a resilient, in the relaxed state obliquely in a direction of insertion of a first track into the cavity protruding into the first connecting claw, or by a track system with such fasteners pushed.

In practice, it happens again and again that fasteners and suspensions of drive rails can be attached only with great effort. This is due in particular to the fact that there are many different mounting options and that the delivery of the drive rail with the drive device does not provide suitable suspension material. By choosing wrong mounting materials, the safety of mounting a drive rail is not necessarily given, so that accidents can occur. Another safety aspect is the fact that the currently available on the market drive rails have a very wide, lower-side passage; which has been set forth by the cited prior art. In such constructions of the drive rails, the opening width directed towards the floor or the like is dimensioned so that a minimum of material is needed in the production. The basic idea of drive rails is based on sufficient stability, which must be ensured if the movable carriage within the drive rail is driven by a rotating force transmission means, for example in the form of a chain, a toothed belt or a rope, by the drive motor of the drive device. The garage door is functionally connected to the carriage via a connection. The disadvantage of known constructions entails that the passage width and so that the opening of the substantially C-shaped profile of the drive rail are much too large. This makes it possible to access during the running of the engine in the interior of the drive rail in. Such an intervention can lead to serious injuries.

The object of the invention is to reduce errors in the assembly of drive rails for garage doors and their drive device and at the same time to make the mounting easier to install and faster executable. Such a drive rail should bring a pleasing appearance with sufficient overall stability and at the same time ensuring safety aspects. Furthermore, a drive rail, which may consist of several drive rail sections, with their sections to be securely interconnected. Due to the selected type of connection of the drive rail sections with one another, the total load capacity of the drive rail may not be reduced.

The object of the invention is solved by the features of claim 1 and a method according to claim 17. The dependent claims provide a further embodiment of the inventive concept again.

To solve a part of the problem, reference is made to a standardized mounting design on a drive rail, which is characterized in particular in that at least one molded mounting receptacle is provided on the upper side of the drive rails. Such a fastening receptacle can, with essentially rectangular drive rail cross-sections, be formed on an upper base and preferably extend over the entire length of the drive rail. The formation of such a drive rail allows a mounting method in which cuts in the drive rail without problems are possible without the ease of assembly is lost and in addition, no additional holes for attachment must be made.

In order to achieve a higher stability of the drive rail during assembly, it is possible in a preferred embodiment that two spaced-apart fastening receptacles are provided on the upper side of the drive rail. The formation of such fastening receptacles is so distanced that they preferably reach as far as the edges of the side walls.

Such a mounting receptacle can be formed substantially C-shaped, which means that, starting from the top of the drive rail, which can be referred to as a base, projections are present, each containing a space. These projections preferably have an undercut, so that with the opening located between the projections, a space is created which is suitable for being able to receive suitable suspension materials. This can be differently shaped elements that can be inserted laterally into the fastening receptacle. It is also possible to use nuts or sliding blocks or special elements that are designed for example as a hammer heads. The hammer heads do not need to be pushed laterally into the mounting receptacles. Rather, these can be inserted from above into the mounting receptacle and then rotated. This creates a Verhakung within the mounting bracket.

By such a standardized embodiment of a fastening, it is possible to screw in the fastening means inserted into the fastening means, which are preferably provided with a thread, suspension materials, which are then attached to an overlying ceiling or other facilities. Such a mounting of the drive rail facilitates assembly enormously, is fast without errors executable and also distinguished by an elegant look, because the side surfaces of the drive rail remain free.

With the use of two spaced-apart fastening receptacles formed therebetween a depression or a channel that can be used to safely receive electrical cables and / or data lines. As a result, an energetic connection to the drive device is considerably simplified because these cables or data lines run above the drive rail and do not have to be mounted separately. At the fixed end of the drive rail they can be moved further into the lintel area.

A further ease of assembly results in a preferred embodiment of the drive rail, characterized in that a connection region of the drive rail is assigned for connection to the drive device. Such a connection region can be connected, for example, with a transmission which belongs to the drive device or else also directly connected to the drive device in a normalized manner. In this case, such a connection region is characterized for example by the fact that a flat mounting surface is provided at one end of the drive rail, in which, for example, mounting holes are included. Such a design makes it possible to mount the drive device in an easy and in particular error-free manner.

Another simplification of assembly is characterized in that the connecting arm, which has a connection between the door leaf and the translationally movable carriage within the drive rail, which allows that in a pre-assembly, the power transmission means can be pre-assembled with the carriage within the drive rail. In order to simplify the connection of the connecting arm with the carriage already located inside the drive rail, the drive rail has at least one mounting opening the bottom in the area of the passage. Such a mounting opening may be arranged at one or both ends of the drive rail. This makes it possible that, for example, in the closed or open position of the door, the connection between the gate and the carriage is carried out so that the connecting arm is first connected to the gate and then via the mounting opening with the carriage. For this purpose, the connecting arm at one end to a connection plate which is screwed through the mounting opening with the carriage. This connection plate has been designed so that in it the connecting arm is rotatably mounted in the direction of the passage. In one embodiment, the drive rail with two mounting holes and the connecting arm in the end position, ie near the drive device, are first connected to the carriage and then to the garage door.

The drive rail according to the invention has a substantially rectangular cross-section, the upper side containing the base with the mounting receptacles and at the same time is C-shaped. This creates an opening to the building floor or the like in the longitudinal direction of the drive rail open passage. Through this passage, the, preferably made of a flat material, connecting arm protrudes and can thus be moved over the carriage and an endless power transmission means which is used as a traction means in the longitudinal direction of the drive rail. As a suitable power transmission means toothed belt or chains or ropes can be used.

A drive rail of the type described above can be made of steel or light metal or plastic and has substantially straight outside sections. The passage has been formed substantially smaller in its width contrary to known drive rails, so that a conscious engagement from below by a person in the drive rail not possible or only under difficult conditions is possible. By such a measure, accidents can be avoided because people repeatedly engage in the opening or closing operation of the garage door into the drive rail.

The stability of the drive rails is of great importance, because through the gate to be moved transverse forces arise, which are eliminated by the drive rail according to the invention, because the drive rail has a much larger moment of resistance than conventional drive rails according to the prior art. Such a trained drive rail can also be produced with greater precision, so that the passage can be made much narrower than is known from the prior art. For this reason, the width of the passage has been made so low that the connecting arm is only a small thickness laterally with sufficient application-related open spaces, freedom of movement (game) is formed. Such a freedom of movement avoids tensions that can arise, for example, due to temperature fluctuations. For safety reasons, therefore, the width of the passage is only 15 mm or less, preferably 12 mm or less, more preferably 11 mm or less or 10 mm or formed below 10 mm. The passage may also be a width of 8 mm or less, preferably 6 mm or less. This shows that the execution width of the passage can be matched to the thickness of the connecting arm. Due to this very narrow width of the passage over the entire length extension of the drive rail and a special stability is achieved. The fact that the surfaces are substantially straight laterally of the formation of the passage, the drive rail also receives a very pleasing appearance. This appearance can be further increased by the fact that the surface can preferably be provided with a colored coating.

Since the door sizes are very different, it is necessary to provide the drive rails in different lengths. In order to make such drive rails transportable, and also to save on transport costs, therefore, the drive rails are divided into several sections as needed and then connected to each other at the construction site before impact, so that the connection area of two drive rail sections can withstand the same loads as a one-piece drive rail. In order to meet these demands, the invention selects the way of a connection in which the drive rail sections on the upper side by a positive and positive fit on the mounting receivers and in conjunction with at least one, but preferably with two equally formed fasteners, executed. This ensures that no connecting means are used at the lateral areas or at the bottom of the drive rail, this also contributes to an attractive appearance.

The drive rail with its upper-side, undercut mounting receptacles, for example in the form of T-slots, as they have already been described, thus also simultaneously offer the possibility of carrying out a connection, not visible from below, of drive rail sections via connecting elements. Such a connecting element, which may preferably consist of two identical components, can securely connect the abutting drive rail sections on the upper side. The connecting element has a base which has a complementary shape to the fastening receptacles and is elongated. The length of this base depends on the loads of the drive rail and surmounted safely after mounting the area of the joint of the drive rail sections to be connected. At the same time, two projecting cantilevers are formed at a distance from one another on this base, in each of whose end regions a bore is contained. The connecting element has material subsidence in the base top on, which are provided with threaded holes. In such a lowering of the material, in each case the free end of the cantilever arm can dip in the mirror-image assembly of two connecting elements. The dimensional design has been chosen so that the holes in the cantilevers are aligned with the threaded holes in the base. By this construction, a secure and accurate fit of the connecting elements with each other and in the mounting receptacles is possible. During assembly, two connecting elements to be joined are placed opposite one another so that threaded screws can be inserted within the bores. These threaded screws are screwed only loosely and thus allow the two interconnected, same connecting elements can be inserted into the grooves of a first drive rail section. Subsequently, the second drive rail portion is also inserted into the still protruding from the first drive rail portion portions of the connecting elements. After an orientation in which the drive rail sections must be against each other butt, the glands are then tightened. By tightening the screws, the base is pulled against the free-standing upper portions of the mounting receptacles, so that by tightening the screws no pressure on the drive rail with its base is formed.

As this description makes clear, the upper portion is used with the projections of the fastening receptacles for both the suspension and for a connection of two drive rail sections to each other simultaneously.

Further advantages and features of the invention will become apparent from the following description in conjunction with the illustrated embodiments.

The FIG. 1 shows a drive rail 1, as is known in the art. The drive rail 1 consists of a base 2, at the ends of angled side walls 7 are formed, which are provided with stiffeners. The ends of the side walls 7 are each provided with short bends 8, so that overall the drive rail includes a cross-sectionally C-shaped design. Between the bends 8, a passage 9 has been formed. The passage 9 has a width 27, this is unrelated to a thickness of a connecting arm 17th

The FIG. 2 gives the inventive design of the drive rail 1 again. This structure of the drive rail 1 is substantially analogous to the drive rail 1 to the prior art, wherein also in the drive rail 1 of a base 2 laterally angled side walls 7 and of which bends 8 are present. Between the ends of the bends the passage 9 is formed with its width 7. As can be seen only the optical representation, the width 27 in the Drive rail 1 has been designed substantially smaller than the width 27 in the drive rail to the prior art after FIG. 1 ,

The FIG. 3 gives the drive rail 1 in a perspective view again, the cross section may be FIG. 5 be removed. In this case, there is the drive rail 1 on its upper side, ie on the side which will be directed to the building ceiling during installation, from the base 2, directed to the ground side side walls 7 and the bends 8. Between the bends 8, the passage 9 is shown , which allows an opening to an inner receiving space 6, the otherwise closed drive rail 1. In the receiving space 6, the bends 8 are formed as planar guide surfaces for the carriage 21. Within the receiving space 6 runs on each side of an endless power transmission means 25th

On the base 2 each fastening receptacles 3 have been formed at their lateral ends. Such a fastening receptacle 3 is characterized in particular by the fact that a space provided with an opening is created, which is essentially C-shaped. In this case, projections 4 are present, which have formed an undercut 5 to the free space. The fact that there is a gap between the projections 4, it is possible to introduce in the free space fastening means in the form of nuts, washers or other fastening materials, if necessary, have a thread and thereby open up the possibility, with not shown suspension materials of various kinds the assembly standardized to be connected.

In the embodiment of FIG. 5 is located between the laterally arranged mounting receivers 3, a channel 11. Such a channel 11 may serve to receive electrical lines and / or data lines that from a building to one end to the drive rail 1 fastened, drive device, not shown continued. Such a design avoids the usually laterally existing cable transitions. So that the electrical cables or lines remain within the channel 11, they can be secured by clips or brackets in position.

From the Figures 3 and 4 is at the end of the drive rail 1, a connection portion 12 can be seen. This connection region 12 serves to connect a transmission or a drive device to the drive rail 1. The connecting region 12 is characterized in that it springs back against the distanced fastening receptacles 3, so that a flat, straight mounting surface 13 is created. Characterized in that the drive rail 1 can be made for example in an extrusion of light metal or by a spraying process in plastic, the drive rail 1 is delivered as a rod material. This rod material can be inexpensively tailored to the desired length or even dispatchable drive rail sections 28, 31, which are interconnected at the construction site. The area in which the drive device or the transmission is to be connected to the drive rail 1 can be processed, for example, by a milling method, so that the mounting surface 13 is formed. Within the mounting surface 13 mounting holes 14 are incorporated for a transmission or the drive device. Furthermore, within the mounting surface 13, an opening 15 and a recess 16 can be incorporated, which can be used to achieve a precise positional fixation between the drive device or the transmission and the drive rail 1.

Of the FIG. 5 can be further seen that the passage 9 is dimensioned in its width 27 so that the connected to the carriage 21 Mounting arm 17 can be changed with sufficient lateral freedom of movement to the lateral bends 8 in its longitudinal position. Contrary to the prior art, the width 27 of the passage 9 has been made much narrower. It has proven to be very effective against unintended interventions in the space of the drive rail 1 when the width 27 measures substantially 12 mm or less. In a particular embodiment, it is possible that the width 27 may also be dimensioned 11 mm or less and in a particularly trained embodiment also 10 mm or less in its longitudinal extension. Depending on the thickness of the connecting arm 17, it is possible that the width 27 can also be dimensioned with 8 mm or less, but in particular also with 6 mm or less. In such a small width 27 only an intentional engagement in the interior of the drive rail 1, for example, only with a tool or the like, executable. It turns out that this type of construction of the small width 27 accidents can be completely avoided by engaging in the drive rail 1.

The interaction of the drive rail 1 with the connecting arm 17 can the perspective view of FIG. 6 be removed. In this case, the connecting arm 17, which is connected at one end to the carriage 21 and at the other end connected to a garage door, not shown, which may be formed as a tilt gate or sectional door, projects out of the passage 9 out.

In order to facilitate the assembly of the formed without protrusions, flat connecting arm 17, for example, in the drive rail 1 in both end regions a mounting opening 20. Such a mounting opening 20 allows that connected to the connecting arm 17 connecting plate 18 passed through the mounting hole 20 and is connected to the carriage 21 located behind it via screw 19. By means of this mounting hole 20 is a created significant assembly performance, so that depending on the placement of the mounting hole 20, the garage door can be operatively connected both in its closed position and in its open position with the connecting arm 17 after installation of the drive rail 1. The resulting at the location of the mounting hole 20 enlargement of the passage 9 may, for. B. are closed by covers, closures or the like.

By the perspective view according to the FIG. 8 the position of the connecting arm 17 in the region of the mounting opening 20 is clarified once again. In this illustration, the circulating within the drive rail 1 power transmission means 25 has been shown.

The FIG. 5 shows a part of the carriage 21, in which via the connecting plate 18 with the screw 19 of the connecting arm 17 is removably attached. It is clear that the connecting plate 18 projects inwardly into the carriage 21 to avoid protruding parts. The connecting plate 18 is constructed so that the connecting arm 17 can perform a rotational movement in the direction of the drive rail 1 and thus the passage 9. The fact that the connecting plate 18 has been brought into the guide surface 24 of the carriage 21, no protruding components are no longer present, so that the guide surface 24 of the drive rail 1 on the guide surfaces 10 of the carriage 21 can slide smoothly. Within the carriage 21 there are free spaces 22 for passage and connection to the power transmission means 25. The lateral conclusion of the carriage 21 form side walls 23. As this previous description of the embodiment illustrates, it is possible that the assembly times are significantly reduced on-site with the drive rail 1 according to the invention and their attachments. In addition, assembly errors are impossible, which leads to an increase in quality.

Another important aspect is the safety of the drive rail 1, which is achieved by the small width 27 of the passage 9.

To reduce transport costs, it is possible to divide the drive rail 1 into two or more drive rail sections 28, 31 and reconnect them on the construction site. This gives the FIG. 10 again, where two drive rail sections 28, 31 bear against each other via a joint 30 and are connected to each other by means of two identical connecting elements 29. In this case, the identical connecting elements 29 against each other, ie offset by 180 ° with each other and connected by fastening screws 32 at the same time with the drive rail sections 28, 31 non-positively and positively.

Leaving out the mounting screws 32 shows the FIG. 11 in that the mutually opposing connecting elements 29 are inserted and connected only to the upper side of the drive rail sections 28, 31.

To build the connecting element 29 is on the FIG. 13 directed. In this case, the connecting element 29 consists of a base 33, which is preferably T-shaped in cross section and thus forms a complementary shape to the mounting receptacle 3. In this case, lateral projections 38 are present, the upper-side bearing surfaces 37 include. This design of the base 33 depends on the design of the top of the drive rail sections 28, 31. Such a compound can the FIG. 12 be taken again in a sectional view. In this case, the drive rail sections 28, 31 have on top of their base 2 fastening receptacles 3 in the form of grooves which include a T-shaped form. The shape of this fastening receptacles 3 is basically possible in a wide variety of training, only it is necessary that the part of the base 33, which is inserted into the mounting receivers 3, has a complementary shape. Starting from the Base 33 are at the top of the connecting elements 29 two spaced apart formed, projecting cantilevers 34 available. In the end region of the cantilever arms 34 each have a bore 35 is present. To reinforce the cantilevers 34, these upper side preferably strip-shaped reinforcements 40. By the FIG. 13 It is clear that the placement of the cantilevers 34 is designed so that when using two identical connecting elements 29, these can be mounted against each other and thus are at a total of the same height. For this purpose 34 recesses 36 are incorporated within the base 33 on the dimensional coordination of the cantilevers. By lowering 36 an unambiguous fixation is achieved with a lower height of the juxtaposed fasteners 29. Within the recess 36 each have a threaded bore 41 is included. The threaded holes 41 are aligned in the joining of the two connecting elements 29 with the holes 35. The formation of the connecting element 29 is in the views of FIGS. 14 and 15 shown again. It becomes clear that the base 33 in the FIG. 14 between the cantilevers 34 and abutment surfaces 37 has a free space, which images the complementary shape of the mounting receptacles 3 in the drive rail sections 28, 31.

In the FIG. 12 this will be clarified once again. There two oppositely directed connecting arms 29 have been shown with their bases 33 in the mounting receptacles 3. The fact that in the bases 33, the threaded holes 41 are included, it will come by tightening the mounting screws 32 to a contact of the contact surfaces 37 at the upper undercuts 5 of the mounting receptacles 3. This means that by the setting of the connecting elements 29 in the drive rail sections 28, 31, no pressure is exerted on the drive rail 1 as a whole and also in its sections. This will avoid causing punctiform loads within the drive rails 28, 31 comes, which could lead to dislocations of the drive rail 1.

In the FIG. 12 the formation of the drive rail sections 28, 31 has been reproduced in a sectional view. As the illustrations of the figures illustrate, neither discs nor further fastening means are used to achieve a secure and highly stable connection of drive rail sections 28, 31 with each other at a joint 30. Due to the design of the fastening receptacles 3 in the base 2 or the base leg 42, it is possible to shorten the length of the drive rail sections 28, 31 so that the circumstances of the installation site or the shipping method. Furthermore, it is avoided by the use of the two same connecting elements 29 that the side legs 7 and the bends 8 burdened by aufzusetzende connectors, scratched and thus unsightly. Such drive rails 1 can be colored, which positively affects the overall appearance.

In the context of the invention, it is also to carry out the formation of the connecting elements in a one-piece mold.
