Description

The invention relates to a rail for a sliding door, in particular for a sliding glass door, the rail being designed both for mounting on a ceiling and on a wall, the rail comprising a main profile, the main profile having a first and a second leg in cross section , wherein the two legs are arranged next to one another in cross-section in an arrangement region and form a leg channel, the first leg comprising a carriage track for moving a carriage on the carriage track.

Such a track is already out DE 32 38 204 A1 known and includes a ceiling leg and a wall leg. Both legs have drilling aids for mounting on the ceiling or wall. A carriage leg is arranged on the wall leg, which extends in cross-section in an approximately horizontal direction. The carriage leg includes a carriage track for a carriage, whereupon the carriage is mounted so that it can be moved by means of rollers. The carriage has two clamping jaws, between which a door leaf made of glass can be fastened in such a way that the door leaf is kept movable while hanging on the carriage. A very similar track is also in EP 2 064 406 B1 disclosed.

The disadvantage of rails of this type is that holes have to be drilled on site for mounting on the wall or ceiling leg. This increases the installation effort on site and also increases the probability of errors, especially in the case of installation by the end customer. For example, it can easily happen to end customers that the drill holes are drilled too large or are placed in the wrong leg. Depending on the design of the rail, another source of error is that other parts of the rail are affected when drilling, for example because the drill pierces the leg after the actual drilling process is complete and damages a part of the rail behind it. In addition, the chips produced during drilling are often perceived as annoying.

Drilling errors can be contained to a certain extent, but to a lesser extent, by providing drilling aids (e.g. in the form of grooves or indentations in the rail material). Drilling aids can and are often attached to both legs, but they have their own disadvantages. For example, drilling aids on the inside of the ceiling leg often cannot be used due to the track in the way. On the other hand, on the outside of the ceiling leg, the drilling aids can impair the external appearance of the rail if the rail is mounted on the wall and the room allows a view of the rail from above. In addition, the risk of the drill piercing the mark with external drilling aids on the slab leg is quite high. Such an error significantly affects the smooth running of the sliding door.

An alternative is to provide the drill holes in the factory either in the wall or in the ceiling leg. This would mean two different products, one only being suitable for ceiling mounting and the other only for wall mounting. However, this increases the effort in production, storage, logistics and distribution and also increases the risk of bad purchases by end customers. Drilling holes in both legs is not an option because the leg that is not used for assembly is visible in many assembly cases.

The invention is therefore based on the object of specifying a rail for a sliding door which is suitable for both ceiling and wall mounting, in which the end customer or the fitter does not have to drill any drill holes on site and it can be ensured at the same time that none of the pre-drilled holes are visible in all assembly cases. At the same time, the rail is preferably inexpensive in terms of production or storage or logistics or distribution.

This object or these objects is/are achieved by a rail for a sliding door, in particular for a sliding glass door, the rail being designed both for mounting on a ceiling and for mounting on a wall, the rail comprising a main profile, the The main profile has a first leg and a second leg in cross-section, the two legs being arranged next to one another in cross-section in an arrangement area and forming a leg fillet with an angle α, the first leg having a carriage track, the carriage track being designed in such a way that on a carriage for a door leaf can be moved along the carriage track, with the second leg having an alternative track for the carriage.

The solution according to the invention is initially based on the finding that rails for sliding doors that can be mounted on walls and ceilings, in particular those with single-glazed door leaves, are generally used indoors and are often mounted by ambitious amateurs. These rails differ significantly from those sliding doors, which have rails integrated into frames, have double or triple glazed door panels, and follow the closure of a building serve outside. From many years of practice it has been found that the sliding doors for end customers must be as easy as possible to install so that expectations do not turn into frustration.

The invention is also based on the finding that by providing an alternative track on the other of the two legs, the rail can be rotated and then mounted in such a way that both legs can be assigned to both the wall and the ceiling. This means that there is no longer a fixed assignment of the legs to the room elements wall or ceiling, as is the case with DE 32 38 204 A1 and EP 2 064 406 B1 the case is. Because the rails disclosed there have only one carriage track, whereby one leg is assigned exclusively to the wall and the other leg only to the ceiling.

It was also recognized that the resolution of the fixed assignment allows only one of the two legs to be pre-drilled at the factory and this one leg (assembly leg) can then be mounted both on the wall and on the ceiling. Because the other leg does not include or need to include holes, aesthetically pleasing rails can be made from all perspectives that do not require on-site drilling, while also being suitable for ceiling and wall mounting. As a result, the task mentioned at the outset is solved in an elegant manner. A further advantage of the invention is that only one product has to be manufactured that is suitable for both room elements--ceiling and wall--so that the manufacturing, storage, logistics and distribution processes are simplified and there are also fewer bad purchases.

Other revelations, e.g DE 83 02 829 U1 or DE 103 23 695 B4 , show two carriage tracks, although both carriage tracks are not located on legs that are arranged next to one another. Instead, there is at least one further leg between them. In addition, there is an angle of 180° between the legs with the carriage tracks ( DE 83 02 829 U1 ) or 360° or 0° ( DE 103 23 695 B4 ).

The expression "arrangement area" preferably means an area of the attachment, which can be designed to be irreversible (e.g. by welding) or reversible (e.g. by screwing).

It is very preferred that the fastening element of the panel can latch with or in the panel mount of the second leg. According to a particularly preferred embodiment, the first leg includes an alternative receptacle for receiving the fastening element of the panel. It is very preferred that the alternative mount has the same cross-sectional shape as the aperture mount. Preferably, the panel mount is arranged on the end of the second leg facing away from the arrangement area. The alternative receptacle may be located on an end of the first leg that faces away from the arrangement area. It is preferred that the panel mount or the alternative mount is arranged on the inside of the second leg or the first leg.

It is preferred that the bezel includes a seal receptacle. The seal receptacle is preferably formed as a longitudinally extending groove. It is preferred that the rail has a sealing element. The sealing element may be designed, for example, as a brush-like element or as a rubber lip with a sliding end.

The panel preferably comprises a main limb and more preferably a secondary limb. The main limb preferably projects downwards in the fastening state as well as in the alternative state of the rail. The main leg is preferably aligned parallel to the first leg or to the second leg. The secondary leg preferably has an extension aligned essentially perpendicularly to the main leg. The main leg is expediently longer than the secondary leg and preferably at least twice as long. The rail is preferably designed in such a way that the secondary leg or the seal receptacle between itself and the opposite first leg or second leg define an opening in cross section through which the carriage or the door leaf can move along the length of the rail.

Particularly preferably, an angle bisector WH of the angle α represents an axis of symmetry of at least one section in the cross section of the first leg and the second leg, at least along a longitudinal section of the rail. Preferably, the angle bisector WH is at least along a length section of the rail an axis of symmetry between the two legs along at least 50%, 70% or 90% of the length of the two legs in cross section. The expression "at least along a longitudinal section" relates in particular to the fact that the first leg preferably has mounting elements, in particular drilled holes.

It is preferred that the rail has at least one stop mount for a stop at a front end. Advantageously, the stop receptacle includes a fillet groove in the leg fillet. It is preferred that the fillet groove is intersected by the bisecting line WH and is formed symmetrically to the bisecting line WH. It is very preferred that the second leg has a mating groove opposite the fillet groove. The counter-groove is advantageously located between the alternative track and the inside of the second leg. It is very preferred that the stop receptacle has the fillet groove and the counter-groove of the second leg in the fastening state of the rail.

The first leg advantageously includes an alternative groove, with the alternative groove preferably being arranged opposite the fillet groove. It is preferred that the alternate groove is located between the alternate track and the inside of the first leg. In an alternative state of the rail, the stop receptacle advantageously includes the fillet groove and the alternative groove.

The rail preferably comprises at least one stop and more preferably two stops, the at least one stop being arranged on one of the front ends of the rail. The stop is expediently arranged in the stop receptacle of the fastening state or in the stop receptacle of the alternative state. The stop is preferably arranged on the leg which faces the ceiling. The stop preferably comprises a stopper arm, which expediently projects downward both in the fastening state and in the alternative state, so that the carriage or the door leaf is stopped by the stopper arm. It is preferred that the stop has a groove leg. The groove leg is expediently connected to the stopper leg. The stop is advantageously configured in an L-shape in a longitudinal section of the rail.

The groove leg is preferably arranged in the stop receptacle or in the fillet groove. The stop or the groove leg is advantageously arranged in the counter-groove of the second leg when the rail is fastened. The stop or the leg of the groove is expediently arranged in the alternative groove when the rail is in an alternative state. The stop or the groove leg is preferably designed in such a way that, with the exception of the longitudinal direction of the rail, it enters into a form fit with the stop receptacle of the fastening state or of the alternative state. The stop may be made of plastic or a metal such as aluminum. The stop can have at least one fixing element, which is used to fix the stop on the first leg or on the second leg. The fixing element can be formed, for example, as a hole or bore so that z. B. the stop is clamped in the stop receptacle with a screw.

The rail advantageously includes an end cap receptacle for an end cap on at least one end face. The rail expediently comprises an end cap for the at least one front end and preferably one end cap each for both front ends. In particular, the end cap may have a covering surface for covering a front end of the rail. The end cap receptacle preferably has at least one slide-in receptacle. Advantageously, the slide-in receptacle is part of the panel. The slide-in receptacle may, for example, comprise two opposite grooves. The end cap expediently comprises a cover fixing which can be pushed into the slide-in receptacle in a form-fitting manner in the longitudinal direction of the rail. The panel fixing expediently protrudes in the longitudinal direction of the rail in relation to the covering surface. It is preferred that the end cap includes a leg fixation. The leg fixation is preferably designed as a longitudinal projection relative to the cover surface. It is very preferred that the leg fixation of the end cap enters into a form fit in at least one direction with the main profile or the first/the second leg or the alternative groove or the counter-groove. The end cap may have a counter bearing which preferably projects in the longitudinal direction of the rail relative to the covering surface. The counter bearing preferably rests on the inside of the second leg in the fastening state or of the first leg in the alternative state. The counter bearing may supplement the form fit of the leg fixation when the leg fixation is in contact with the alternative groove. The end cap may have an alternate bearing. With the help of the alternative bearing, the end cap can be turned in such a way that the end cap can be inserted into the end cap receptacle at the other end of the rail in such a way that the alternative bearing takes over the function of the counter bearing.

The end cap may include a spacer. The spacer element is expediently designed in such a way that it protrudes in the direction of the wall or ceiling in relation to the first leg or the second leg or the main profile. The spacer element can preferably be changed with regard to the distance from the ceiling or wall. For this purpose, the spacer element can have a first predetermined breaking point, with which a first spacer section can be removed from the spacer element. The spacer section may be, for example, 5 mm in extent in the direction of the wall or ceiling. The spacer element can also have a second predetermined breaking point and a second spacer section, through which the spacer element can be shortened by a further 5 mm, for example.

According to a very preferred embodiment, the first leg and/or the second leg has at least one mounting element, for example a hole or drilled hole, and more preferably two or more mounting elements or holes or drilled holes for attachment to a ceiling or wall. It is particularly preferred that only the first leg has the mounting element or mounting elements.

An exemplary embodiment according to the invention is explained with reference to the following four figures. Show it

• 1 a cross section through a rail according to the invention of a sliding door with carriage and door leaf,
• 2 a perspective view of a stop of the rail 1 ,
• 3 another cross-section through the rail 1 with an end cap and
• 4 Figure 1 shows a perspective view of the end cap 3 .

1 shows a rail 1 according to the invention for a sliding door, with a carriage 8 for a door leaf 9 being movably mounted on the rail 1. For this purpose, the carriage 8 comprises a running body 36 in the form of a roller and a bracket 37 for fastening the door panel 9 to the carriage 8. The running body 36 sits on a carriage track 7 of the rail 1, so that the door panel 9 runs along the length of the rail 1 is movably mounted. This construction is particularly suitable for sliding doors inside buildings and outside showers. The preferred material of the door leaf 9 is glass, although other materials such as wood or plastic can also be considered.

The rail 1 according to 1 comprises a main profile 2, which according to the invention has a first leg 3 and a second leg 4. The two legs 3, 4 of this exemplary embodiment are arranged or fastened to one another in an arrangement area 5 in such a way that the arrangement area 5 and thus the entire main profile 2 is designed integrally and therefore in one piece. The main profile 2 preferably comprises aluminum and more preferably mainly aluminium. The two legs 3, 4 are arranged relative to one another in such a way that they enclose a leg channel 6 between them, which spans an angle α.

While the first leg 3 has the carriage track 7, the second leg 4 includes an alternative track 10. The alternative track 10 of this exemplary embodiment is identical to the carriage track 7 in terms of cross section, so that the running body 36 not only runs on the carriage track 7, but also on the Alternative lane 10 can drive. In the present exemplary embodiment, the rail 1 is attached to the wall, so that the first leg 3 is connected to the wall. For this purpose, preferably includes the first leg 3 mounting elements, which, however, neither in the 1 are still shown in the other figures. The mounting elements can be, for example, holes or bores, with the help of which the first leg 3 can be screwed to the wall in a known manner.

In the present exemplary embodiment, only the first leg 3 has the assembly elements. If the user of the rail 1 has planned to mount it on the ceiling, the rail 1 can be rotated in such a way that the first leg 3 is not connected to the wall but to the ceiling. For this purpose, the rail 1 must be rotated accordingly - once lengthwise by 180° and then again by 90° clockwise of the cross section. After these two rotations, the rail 1 has the same as in 1 shown position, but then the first leg 3 is no longer facing the wall, but the ceiling. In other words, the first leg 3 and the second leg 4 swap their position as a result of this double rotation, so that when the rail 1 is installed on the ceiling, the carriage 8 is no longer movably mounted on the carriage track 7 but on the alternative track 10.

This makes it possible that only one of the two legs 3, 4 is provided with assembly elements, so that the other of the two legs 4, 3 has a visually flawless surface. As a result, one and the same rail 1 offers the possibility of mounting both on the wall and on the ceiling, while at the same time an optically perfect surface of the other leg is guaranteed. It is also advantageous that there are mounting elements, preferably in the form of holes, so that the user has the least possible effort in terms of fastening the rail 1 to the wall or the ceiling.

An angle bisector WH of the angle α is preferably at the same time an axis of symmetry between the two legs 3, 4. This symmetrical arrangement with respect to the angle bisector WH particularly simplifies the exchange of the first leg 3 with the second leg 4 and vice versa, which is necessary for flexibility. Thus, the second leg 4 may have a panel mount 18 for receiving a panel 11 . The panel 11 serves in particular to protect the inner workings of the rail 1 and also for aesthetic purposes. In this exemplary embodiment, the first leg 3 includes an alternative receptacle 19 for the screen 11 if the first leg 3 is to be fastened to the ceiling. Since one and the same panel 11 should be able to be held not only in the panel mount 18 but also in the alternative mount 19 with a preferred fastening element 24, a symmetrical configuration with respect to the angle bisecting line WH is also recommended with regard to the panel mount 18 and the alternative mount 19.

The panel 11 preferably includes a seal receptacle 22 which can accommodate, for example, a seal in the form of a brush for sealing against the carriage 8 or the door leaf 9 . The panel 11 of this exemplary embodiment has a main leg 20 which, depending on the assembly situation, faces either the first leg 3 or the second leg 4 and also has approximately the same length as the first leg 3 or second leg 4 . The screen 11 may also include a side limb 21, which is preferably associated with the seal receptacle 22. The secondary leg 21 is expediently shorter than the main leg 20 because the secondary leg 21 must leave sufficient space for the carriage 8 or the door leaf 9 between itself and the alternative receptacle 19 .

The main profile 2 preferably has a fillet groove 12 or part of a stop receptacle 12, 13, 14 on an inside of the arrangement area 5 or in the area of the leg fillet 6. Advantageously, the carriage track 7 forms an alternative groove 14, whereas the alternative track 10 expediently forms a counter-groove 13. In this exemplary embodiment, the fillet groove 12 and the counter-groove 13 are arranged opposite one another, so that a stop 15 can be fastened in the rail 1 or in a stop receptacle 12, 13 of the second leg. The stop 15 can have a groove leg 16 and expediently a stopper leg 17 . The groove leg 16 may have such a shape that it can be pushed into the fillet groove 12 and the counter-groove 13 at the same time and only has one degree of freedom of movement in the longitudinal direction of the rail 1 or the main profile 2 .

The stop 15 is in 2 shown in perspective. It is particularly clear that the stop 15 can have fixing elements 38 in the form of holes. With the help of the fixing elements 38, for example by screwing, the stop 15 of this exemplary embodiment can be firmly connected to the main profile 2 or to the second leg 4, as a result of which the stop 15 can absorb forces to a sufficient extent.

With regard to the bisecting line WH, the alternative groove 14 is preferably formed symmetrically to the counter-groove 13 . The same also applies to the fillet groove 12, which is preferably inherently symmetrical with respect to the bisecting line WH. This symmetry makes it possible for the stop 15 to be connected to the first leg 3 if necessary, if the first leg 3 is not fastened to the wall but to the ceiling.

In 3 is a cross section through the rail 1 from 1 shown, although the carriage 8 and the door leaf 9 as well as the stop 15 have been omitted for better visibility. This gives a clear view of a preferred end cap 25, which can close off the rail 1 at both ends. The end cap 25 preferably includes a covering surface 35 and may be accommodated in an end cap receptacle 13 , 14 , 23 of the rail 1 be acceptable. The end cap receptacle 13, 14, 23 can have a slide-in receptacle 23, with the slide-in receptacle 23 preferably being part of the panel 11. The insertion receptacle 23 of this embodiment includes two grooves which are opposite to each other. The end cap 25 advantageously has a panel fixation 27 in the form of a projection which can advantageously be accommodated in a form-fitting manner in the insertion receptacle 23 of the panel 11 . The end cap 25 of this exemplary embodiment comprises a leg fixation 26 which is preferably in the form of a projection. The fixation of the legs can be accommodated in a form-fitting manner in the alternative groove 14 - and alternatively also in the counter-groove 13 .

It is preferred that the end cap 25 includes a counter bearing 28, in particular in the form of a projection in the longitudinal direction of the rail 1. In this exemplary embodiment, the counter bearing 28 and the leg fixation 26 are designed in such a way that both together prevent mobility of the end cap 25 in the vertical direction. The end cap 25 is advantageously designed in such a way that it can only be pushed in in the longitudinal direction of the rail 1 and otherwise there is a positive fit. The leg fixation 26, the panel fixation 27 and the counter bearing 28 serve this purpose in particular. The end cap 25 may also have an alternative bearing 29, which is designed in such a way that the end cap 25 can also be used on the other front end of the rail 1 and in which case the alternative bearing 29 assumes the position of the counter bearing 28 from the other end of the rail 1.

The end cap 25 is in 4 shown in perspective to show in particular the extension of the end cap 25 in the longitudinal direction of the rail 1. The end cap 25 preferably includes a spacer element 30. The spacer element 30 of this exemplary embodiment may have a first spacer section 31 and a first predetermined breaking point 32. The end cap 25 preferably comprises plastic. It is possible that the spacer element 30 is broken at the first predetermined breaking point 32 so that the first spacer section 31 can be removed. The first spacer section 31 may have a width of 5 mm, for example. The same may apply to an optional, second spacer section 33 which can be connected to the rest of the end cap 25 via a second predetermined breaking point 34 . The elements 31, 32, 33, 34 of the spacer element 30 therefore allow two distance steps between the main profile 2 and the wall or the ceiling. In this way, for example, spacer strips between the main profile 2 and the wall or the ceiling can be covered. The end caps 25 of this initial example can thus be used for different lengths on both front ends and in both installation situations. One and the same end cap 25 can thus be used in a total of four installation situations, each with two distance stages.

Likewise, the panel 11 and the stop 15 or the two stops 15 are designed in such a way that they can be used for both installation situations. In addition to low unit costs for the rail 1, this also means that the user does not have to work with alternative parts, which further increases the ease of installation.
