The disclosure relates to a seal for a sliding door and a sliding door with the seal.

From the one with the publication number EP 1 860 272 A2 published European patent application is known a sliding door, the door leaf is sealed in the closed state of the door around against the floor and a door frame.

The present invention has for its object to improve the known from the aforementioned patent application sliding door and its seal.

This object is achieved by a sliding door with the features of claim 1. In a sliding door according to the invention with a door leaf, arranged in a groove at a lower end of the door leaf bottom seal and a guide element for guiding the door leaf when opening or closing the door, which engages between a housing and a groove wall of the groove in the groove, is in Nutgrund between the housing of the bottom seal and the groove wall and above the guide member arranges a first seal.

According to the invention, the sliding door may comprise a retaining rail which has at least one fixing structure for fastening the retaining rail to an upper end of a door leaf of the sliding door and has at least one attachment structure for fastening the retaining rail to at least one sliding door carriage, wherein the Holding rail has a first receptacle for a second seal. The first receptacle of the retaining rail may be a groove with a groove bottom and groove walls.

Unlike the prior art, the door leaf is not attached directly to the carriage or the carriage door. Rather, the door leaf is attached to the support rail and attached to the carriage of the sliding door.

In addition, the first receptacle is provided in the retaining rail, in which the second seal, preferably a self-releasing when closing the door seal can be used. In contrast to the prior art, the second seal may be attached to the door leaf, while in the known sliding door, the seal is attached to the frame.

The retaining rail may have a second receptacle as fastening structure for fastening the retaining rail to the at least one carriage. The second receptacle of the retaining rail is preferably a groove with a groove bottom and groove walls, wherein the groove walls have undercuts. This results in inwardly cantilevered edges behind which engages a fastener for fixing the door panel to the carriage. The fastening means may for example be a screw, wherein the screw head is arranged in the second receptacle and the screw shaft engages between inwardly projecting edges of the groove walls.

The groove bottom of the second groove is parallel to the groove walls of the first groove.

As a fastening structure for fastening the retaining rail to an upper end of a door leaf, the retaining rail can have at least one recess in at least one groove wall of the first groove. Preferably, the retaining rail has aligned recesses in the groove walls of the first groove and in the groove bottom of the second groove. Through the aligned recesses, it can be In this case act around round holes, screws can be guided, with which the retaining rail can be screwed to the upper end of the door panel.

As an attachment structure for fastening the retaining rail to an upper end of a door leaf, the retaining rail can alternatively or additionally have a flat surface on which the upper end of the door leaf can lie. Furthermore, an adhesive may be provided, by means of which this flat surface is glued to the upper end of the door leaf. The flat surface of the retaining rail may be formed by the lower groove wall of the first groove. The door leaf preferably has at the upper, the holding rail end facing also a flat surface on which abuts the flat surface of the support rail.

Alternatively or additionally, may be provided as a fastening structure for attachment of the retaining rail at an upper end of a door leaf, a clamping mechanism by means of which the door leaf can be clamped.

Furthermore, a sliding door according to the invention may comprise a compensating means with a third seal for sealing a gap between a door leaf of the sliding door and a frame of the sliding door or a wall. In this case, the compensation means on attachment structures for attachment to the door leaf or on the frame or the wall. The attachment structures are adapted and arranged to adjust an angle between the door panel or frame and the compensating means to compensate for non-perpendicular alignment of the frame or wall.

Since the leaves of a mounted sliding door due to the suspension of the carriage are usually always aligned vertically, the walls in which the door opening is arranged, which is closed by the sliding door, are often not aligned vertically, it may be in sliding doors according to the prior Technique occur that the third seal sealingly abuts in one upper or lower area, but in the other area is lifted from the counterpart and results in a gap through which air or smoke flow or noise can be transmitted.

With the compensation means, it is now possible to compensate for the non-perpendicular orientation of the door. For this purpose, the compensation means can be designed in various ways. It can also be attached either to the non-vertical wall. The attachment via the attachment structures then takes place such that the compensation means has at least one edge or surface on which the third seal can be attached or the third seal can rest against the door closed.

The fastening structures for attachment to the door leaf or to the frame or the wall may comprise at least one slot. It can be provided a plurality of parallel, rectilinear slots. It is also possible that at least one arcuate slot and a round hole is provided in the center of the arc.

The object underlying the invention is also achieved by the use of a first seal for insertion into a groove in a lower end of a door leaf of a sliding door for sealing a gap between a housing of a bottom seal and a groove wall of the groove, wherein the first seal for Attachment between the bottom seal and the groove wall, preferably in the bottom of the groove is suitable and furnished.

The first seal may have a sealing profile which has elastic retaining elements. By means of these elastic holding elements, the first seal between the bottom seal and the groove wall can be clamped. It is also conceivable that the first seal per se is elastic and suitable for clamping between the groove wall and the housing of the bottom seal and is set up.

The in the Figures 1 to 3b , especially in the FIG. 1 shown arrangement with the retaining rail 20 serves on the one hand the attachment of a door leaf 10 of a sliding door on a carriage S and on the other hand, the inclusion of an automatically releasable sliding second seal 30th

The retaining rail 20 (see first Fig. 1 ) preferably has a uniform cross-sectional profile over its entire length and is preferably cut to length from an aluminum extruded profile. In places, however, the cross-sectional profile deviates from the uniform cross-sectional profile due to recesses or holes 214, 23.

But it is also possible that the retaining rail 20 has different cross-sectional profiles over the length, in particular at the ends of the retaining rail.

The cross-sectional profile of the retaining rail 20 has an area on the C-shaped. This region forms a first receptacle 21 for receiving the second seal 30. A second region of the cross-sectional profile is approximately U-shaped and forms a second receptacle 22 and a fastening structure for fastening the retaining rail 20 to the carriage S.

The first receptacle 21 and the second receptacle 22 may also be described as grooves. The groove of the first receptacle then has groove walls 211, 212 which are connected by a web 213. The groove of the second receptacle 22 has groove walls 221, 222, which are connected by a web, which at the same time forms a groove wall 211 of the two groove walls 211, 212 of the first receptacle 21.

The groove walls 211, 212 of the first receptacle are free of undercuts, which facilitates the insertion of the second seal 30 into the first receptacle 21.

In the groove wall 211, at least one threaded bore 214 is preferably provided in the vicinity of the web 213. In this threaded bore 214, a threaded pin 40 may be screwed. A tip of the grub screw presses into a housing 32 of the second seal 30, thus fixing the second seal 30 in the first receptacle. The threaded pin 40 preferably has a hexagon socket key surface, which allows easy handling even with a hanging on the running rail R sliding door.

Furthermore, a plurality of pairs of aligned round holes 23, 24 are provided in both groove walls 211, 212 of the first receptacle. Each round hole 23 is provided in the groove wall 211 and has a Diameter which is so large that a screw 130 including its head can be passed through the round hole 23. The round holes 24 in the groove wall 212, however, have a smaller diameter, which is dimensioned so that, although a shaft of a screw 130 can be passed, but not the head.

The screw 130 is a countersunk screw. The edge of the round hole 24 in the groove wall 212 is lowered, so that the head of the screw 130 can be completely received in the round hole 24.

The screw 130 serves to attach the retaining rail 20 to the door leaf 10. For this purpose, the screw 130 is passed through the second receptacle 22 and through the circular holes 23 and inserted into the round holes 24, and is then screwed into the door leaf 10.

The groove of the second receptacle is designed so that the screw 130 can be passed between the groove walls 221, 222 of the second receptacle. The smallest distance between the groove walls 221, 222 is therefore greater than the diameter of the head of the screw 130th

The groove walls 221, 222 of the second receptacle 22 have edges that cant inwardly, whereby the groove walls 221, 222 are undercut. The undercut edges of the groove walls 221, 222 can be engaged behind by heads 52 of screws 50. Shanks 51 of these screws 50 pass through the gap between the edges of the groove walls and protrude outward from the second receptacle 22. With nuts 70 placed on the shanks 51, the screws 50 can be fixed in the second receptacle 22. The ends of the screws 50 can be screwed into the carriages S and secured there with additional nuts 80 placed on the screws 50.

The voltage applied to the door leaf 10 outside of the groove wall 212 has a groove along the retaining rail 20. In this groove, a seal 120 may be used, which may seal between the support rail 20 and the door panel 10 resulting column.

Between the nuts 70 and the screw heads 52 on the one hand and the retaining rail 20 on the other hand washers 60 may be provided. Also on the nuts 80 Unterlegescheiben 60 may be provided.

The carriage S of the sliding door are preferably arranged displaceably in rails R.

If a door leaf 10 is attached to the carriage S via the retaining rail 20, the height and / or orientation of the door leaf can be adjusted by a skillful use of the nuts 70, 80 (see FIG Fig. 3a to 3c ). This method for adjusting the height and / or orientation can also be used for sliding without a support rail, in which the screws 50 are either freely rotatable, indirectly or directly on the door leaf or in threaded bushes directly or indirectly attached to the door leaf. For this purpose, the lower, applied to the support rail 20 nut 70 is released. Also, the upper, applied to the carriage nut 80 is released. Both nuts 70, 80 are rotated against each other and countered. The countered nuts 70, 80 can be rotated simultaneously without the one or the other nut 70, 80 can be rotated on the screw 50. Ie. the moments introduced into the nuts 70, 80 lead to a rotation of the screw 50. This makes it possible to further screw the screw 50 in the carriage S or to solve this slide S.

The in the FIGS. 4 and 5 shown sliding door is mounted on the carriage S and the track rail R on a panel V, which is fixed to a wall W. In the open state of the door, a second seal 30 inserted in the first receptacle 21 of the retaining rail 20 is in an untripped state. In other words, a sealing profile 31 fastened to a retaining profile 33 lies substantially within the first receptacle 21.

In the closed state of the sliding door, however, a front side of the housing 32 of the second seal 30 and preferably also the support rail 20 outstanding trigger (not shown) is pressed. This leads via a non-illustrated and unspecified, known from the prior art mechanism for displaced from the first recording arrangement of the holding rail 33 and the sealing profile attached thereto 31. The sealing profile 31 is then sealingly against the panel V.

The sliding door also has an automatically releasable sliding bottom seal 90. This is arranged in a groove in a lower end face of the door leaf, as for example from the document EP 1 860 272 A2 is known. The bottom seal 90 may in principle be made the same as the second seal 30 in the first receptacle 21. Thus, the bottom seal 90 also includes a housing 92, a trigger (not shown), a mechanism (not shown) for transmitting the movement of the trigger , a support rail 95 driven by the mechanism, and a seal profile 91 fixed to the support rail 95.

The bottom seal 90 can be attached to the door leaf 10 via retaining brackets 93, which are inserted into the housing 92 at the end, and screws 94.

The groove in the lower end side of the door leaf 10 is milled out wider than would be necessary for receiving the bottom seal 90. Since the housing 92 of the bottom seal 90 abuts on one side on a wall of the groove in the lower end face, a gap remains on the opposite side between the housing 92 and the other wall of the groove. This gap serves to receive a guide element 11, which is fastened to the floor F and has a wing projecting into the gap. By the guide member 11 of the door 10 is guided at its lower end when moving.

In a groove bottom of the groove provided in the lower end face of the door leaf 10, a first seal 100 is provided. This first seal 100, which preferably consists of an elastic sealing profile seals against a draft or a sound transmission through the gap between groove wall and seal housing 92 and groove bottom and seal housing 92.

The first seal 100 has elastic retaining elements 101, which deform when inserting the first seal 100 in the gap and hold the seal frictionally in the gap. The holding elements 101 are preferably in a longitudinal direction of the first seal 100 extending lamellae or wings.

In the Figures 6a to 8c three different embodiments of sliding doors are shown with compensating means according to the invention. In the Figures 6a to 8c are used for parts that correspond to each other in function the same reference numerals. There are also for parts that correspond to each other in the function in the Figures 6a to 8c the same reference numerals are used as in the FIGS. 1 to 5 ,

The in the Figures 6a to 8c shown sliding doors have a door leaf 10 which hangs on a support rail 20. The retaining rail 20 is connected to the door leaf 10 via screws which are screwed into the upper end side of the door leaf 10. On the support rail 20 screws 50 are mounted, which connect the support rail 20 with carriage S, which are guided in a guide rail R slidably. The door leaf 10 can be aligned by means of the screws 50 and by means of nuts 70, 80 placed on the screws.

The door leaf 10 depends approximately perpendicularly viewed from the side. A wall W with a door opening that can be closed by the door leaf is often not perpendicular to what is in Fig. 6d something is exaggerated. Due to the almost perpendicular hanging of the door panel 10 and the perpendicular deviating wall, a gap between the door panel 10 and the wall W is wider at one end than at the other end. This presents problems in sealing the gap in the closed state of the door with a third seal 150 attached to the door panel 10 or the wall.

By compensating means 160 according to the invention, this problem will be eliminated. The compensation means 160 are suitable and arranged to compensate for the deviation of the wall W from the perpendicular.

If a seal with seals 140 takes place between the door leaf 10 and a panel V of the sliding doors, it can be ensured by a vertical alignment of the panel that the problem of gaps of different width at the different ends does not occur.

The compensating means 160 is in the in the FIGS. 6a to 6d Sliding door shown formed in two parts and has a rectangular cross-section bar 163, which extends at least over the entire height of the door leaf 10, but advantageous from Floor F extends over the door leaf 10. The strip 163 has a longitudinal slot which extends over the entire bar 163. Transverse to the slot 163 threaded holes are provided in the bar.

The compensating means has as a second part an angle bar 162 on which the bar 163 is attached. A first leg of the angle bar 163 is attached to the wall by screws 190. On a second leg, the bar 163 is attached. The strip 163 is attached to the longitudinal slot on the second leg of the angle bar 162.

In the second leg of the angle bar 162 slots 161 are provided which are provided at right angles to the main extension direction of the angle bar 162. The distance of the slots 161 corresponds to the distance of the threaded holes in the bar 163. Screws 180 are screwed into the threaded holes of the bar 163 and pass through the slots 161 in the angle bar 162. The bar 163 and the angle bar 162 are secured by these screws 180 together. If the screws 180 are somewhat loosened, the bar 163 can be rotated relative to the angle bar 162, whereby a vertical alignment of the compensating means 160 is possible.

On the compensating means 160, the third seal 150 is mounted, which seals the gap between the wall W and the door leaf. Due to the vertical alignment of the compensating means 160, the gap between the door leaf 10 and the wall is the same width at all points, so that a problem-free sealing is possible.

While in the example of FIGS. 6a to 6c the compensating means 160 is attached by means of the angle strip 162 on an outer side of the wall W, the compensating means in the example of FIGS. 7a to 7d mounted in the soffit of the door opening in the wall W. The Attachment of the compensating means takes place directly on the wall W by means of screws 180, which are passed through transversely to the main extension direction provided slots 161 in the compensating means 160. By means of the elongated holes 161, it is possible to fasten the compensation means 180 aligned perpendicular to the wall W.

In contrast to the examples of FIGS. 6a to 7d is at the sliding door according to the FIGS. 8a to 8c the compensating means 160 attached to the door leaf 10. The compensating means 160 is formed by an angle strip, for example, a rectangular bent sheet metal. The compensating means 160 extends over the height of the door leaf 10. It is attached to a lateral end face of the door leaf 10. For this purpose, 160 elongated holes 161 are provided in a first leg of the compensating means, which extend transversely to the main extension direction. By means of the elongated holes 161 guided screws 180, the compensating means is screwed to the door leaf 10. Through the elongated holes 161, an alignment of the compensating means is possible in parallel to the attached to the wall W third seal 150. The attached to the door leaf 10 legs of the compensating means 160 is covered by a cover 200, which also covers the slots 161 visually appealing.

In contrast to the examples of Figures 6a to 7c is in the example according to the FIGS. 8a to 8c the third seal 150 is not attached to the balancing means 160. This is instead attached to the wall W and the second wing of the compensating means 160 is in the closed state of the door to this third seal 150 at.
