Description

sliding door

The invention relates to a sliding door, in particular a sliding glass door, with a door, which is guided with a drive in a track rail, a limiting the path of the door limiting device, a damper unit with retraction function and a coupler, which engages with an Angreifteii the damper latching, wherein the damper unit first slows down the door during the process towards an end position and then drives it into the end position

It is known to provide sliding doors with a damper which slows down the Schüeßbewegung before reaching the Endanschtages, so that a hard hitting the door leaf is prevented against the end stop. The damper absorbs the kinetic energy of the door leaf during the closing movement of the sliding door. However, such a damper does not ensure that the door! exactly reaches its closed position and remains there. It could happen that the door bounces when impacting against an end stop from this and moves back again. Furthermore, dampers are known which are additionally equipped with a spring which draws the engaging part of the damper in the direction of the damper end division. With such a damper, which may be attached to both the door leaf and on the running rail, it is achieved that is triggered by the attack of a coupling part on the engaging part of the damper of the damper. If the door leaf has a high speed, it is slowed down by the damping function of the damper. Thereafter, the tension force of the spring arranged in the damper predominates, so that this causes the door leaf to be driven gently against its damping force into its end position.

In sliding doors, in principle, the problem of mutual coordination between the stationary connected to the track elements - 7 - and the elements connected to the door leaf. When installing, great care must be taken to ensure that the closing position of the door leaf is exactly taken with a damper. In this case, a precise vote of the position of the engaging part and coupling part is required.

From DE 10 2009 005 441 AI the applicant a sliding door is known in which the limiting device forms a structural unit with the damper. This unit is arranged on the running rail. The coupler is formed as an arm extending parallel to the track, which protrudes from the drive and has an abutment surface which cooperates with the restriction device. The arm is formed according to DE 10 2009 005 441 AI from a strip of flat material and elastic. Since in this sliding door formed as an arm coupler abuts against the limiting device, it can lead to an elastic deformation of the arm, so that a defined position of the stationary arranged on the running rail components and arranged on the door components can not be guaranteed. This can cause damage to the damper or even to the door leaf. In addition, the provision of the coupler on a parallel to the running rail arm is a very complex construction, which is costly and leads to a drive with relatively large dimensions.

The invention is therefore based on the object to further develop the known from the prior art sliding door, so that the risk of malfunction is avoided by deforming the coupler, at the same time a compact design of the drive is made possible. In one embodiment of the invention, a simple assembly of the sliding door is to be made possible, with a faulty arrangement of damper unit, coupler and limiting device is virtually impossible.

The sliding door according to the present invention is defined by claim 1. The invention provides a sliding door with a running rail, one on it with a at least one drive guided Türfiügei and the running path of the door delimiting limiting device, a damper unit with retraction function and a coupler, which engages detent with an engaging portion of the damper unit, before, wherein the damper unit slows down the door during the process towards an end position and then in the end position is driving. The invention is characterized in that the coupler is arranged at the rear end toward the end position on the drive.

The coupler is arranged on the drive at the rear end of the drive in the direction of the end division. In other words, when the drive is moving towards the end position, the coupler is at the rear end of the drive. Before the copter engages with the attacked, the drive is thus moved to a large extent in the area of the damper unit. During deceleration of the movement of the drive into the final division, the damper unit thus exerts a pulling movement on the drive. When executing the feed function then the drive is pushed by the damper unit in the end position. The fact that the coupler is arranged at the rear end of the drive in the direction of travel, it is avoided that the coupler carrying part of the drive is deformed by the interaction of the drive with the limiting device. As a result, a malfunction of the damping of the drive, which can lead to destruction of the damper unit or the door, avoided.

In addition, it has been found that can be realized by the inventive design of the drive a very compact drive. The construction according to the invention moreover makes it possible for the drive to be fastened to the door leaf in such a way that the roller is arranged very close to a lateral edge of the door leaf, thereby enabling a particularly advantageous guidance of the door leaf. In this case, no projection of the drive to the door is necessary. In addition, can even the door leaves over the drive in the direction of the end position, so that in the end position the door leaf is flush with the running rail. This is possible, for example, by the limiting device cooperating with a part of the drive, which is arranged laterally of the door leaf.

Of course, it is possible for a sliding door according to the invention that two drives according to the invention are attached to a door leaf, wherein these are arranged mirror-inverted. With a second damper unit, which is likewise arranged in a mirrored manner with respect to the first damper unit, it is thus possible for the door leaf of the sliding door according to the invention to be moved when moving into both end positions, i. both the closing pitch and the open position, braked and guided accordingly. When providing two drives, an advantageous guidance of the door leaf is possible because the drives can be arranged widely spaced due to the compact design.

A development of the invention provides that the damper unit and the limiting device have mutually adapted positioning elements for the defined positioning of the limiting device on the damper unit.

By providing positioning elements, a defined positioning of the limiting device on the damper unit is made possible and at the same time a faulty arrangement on the limiting device is avoided. In this case, the damper unit can first be mounted in the running rail in a simple manner, before the limiting device can be fastened to the running rail at a position defined by the positioning elements relative to the damper unit.

According to the invention it can be provided that the drive has a length which is less than the length of the damper unit, wherein the drive in the End position is completely in the region of the running rail, in which the damper unit is arranged. Thus, a particularly compact design of the drive is realized.

At the same time, the damper unit has a sufficient size to accommodate the necessary for a reliable damping and collection function of the door leaf elements.

The invention advantageously provides that the limiting device has a first abutment surface and the drive has a second abutment surface on the end facing towards the end position, which abut each other in the end position. The provision of two stop surfaces makes it possible to limit the movement of the drive in a particularly advantageous manner. In this case, stop buffers may be provided on one or both stop surfaces, which cause a gentle impact of the drive on the limiting device.

The distance in the longitudinal direction of the running rail between the engaging part of the damper unit in a damper end position and the first stop surface of the limiting device corresponds to the distance in the longitudinal direction of the running rail between the coupler and the second Anschiagfläche the drive. In this way it can be ensured that upon reaching the previously defined damper end position, the drive strikes against the first stop surface of the limiting device with the second stop surface. It is provided in particular that the damper end position is a position in which the damper unit is not fully retracted. This can prevent that before or when reaching the end position of the drive it comes to a striking of the damper unit. Due to the fact that the drive always strikes against the limiting device due to the construction according to the invention, before the damper unit is completely retracted, damage to the damper unit is avoided. According to a preferred embodiment of the invention, it is provided that the positioning elements of the damper unit and the limiting device have a shape adapted to one another. In this way, an arrangement of the limiting device to the damper unit in a defined position in a particularly simple manner possible.

It can be provided that the positioning element of the limiting device is a dowel pin and the positioning element of the damper unit adapted to the dowel hole. Such positioning elements are manufacturable in a particularly simple manner and errors in the assembly are avoided since positioning elements can only be brought together in one way. Of course, it is also possible that positioning elements are used in a different form or that a dowel pin on the damper unit and a bore adapted to the dowel pin is arranged on the limiting device.

A preferred embodiment of the invention provides that the coupler engages in a recess of the engaging part of the damper unit, wherein the coupler is preferably a protruding from the carriage nose. Such an embodiment of the copier has proven to be particularly advantageous. In particular, when the nose formed as a coupler protrudes upwards from the drive, it is advantageous, since in the engaging into the recess of the engaging part a change in height of the drive, for example by a height adjustment of the drive, only leads to a displacement of the nose, so that slipping out of the coupler is prevented from the recess. A method of the drive over slight bumps thus does not lead to slipping out of the coupler part of the recess of the engaging part. According to a preferred embodiment of the invention it is provided that the engaging part of the damper unit is guided in a slotted guide. Such a guide of the Angriffteils is particularly advantageous because the orientation of the recess of the Angriffteils can be changed via the slotted guide. As a result, a reliable engagement of the coupler is ensured with the engaging part during the damping and retraction phase by the Dämpferetnheit.

It can be provided that the engaging part of the damper unit is designed as a fork. About a fork, the invention provided in the recess recess can be formed in a simple manner. The trained as a fork engaging part can be designed to be pivotable. It can be provided that, when moving the drive in the direction of the end position, the slide guide causes the pivoting of the fork from a starting position in a pivoted position and holds the fork in the pivoted position. When moving the drive from the end position, the slide guide can initially hold the fork in the pivoted position and, in order to reach the starting position, pivot the gift! cause.

The provision of the slotted guide thus allows in a simple manner that the trained as a fork attacking part while moving the drive in the direction of the end position both absorb a force exerted by the drive force and transmitted to the damper unit and exerted during the collection function of the damper unit Force can transfer to the drive. Furthermore, the slotted guide allows the process of the drive from the end position, a force can be transmitted from the drive to the damper unit, so that a spring of the damper unit can be stretched. The damper unit can be arranged above or to the side of a track of the track rail.

A preferred embodiment of the invention provides that the damper unit has a Koibenzyiindereinheit and a parallel to the Koibenzyiindereinheit arranged spring. About the Koibenzyiindereinheit a damping function can be realized in a particularly advantageous manner. The arranged parallel to the Koibenzyiindereinheit spring, however, can cause the collection function of the damper unit.

The damper unit may be individually and together with the limiting device on the running rail in the longitudinal direction to be displaced and locked.

The sliding door according to the invention is particularly, but not exclusively, as a sliding glass door, the drive is part of an existing metal upper bracket for the glass door leaf. Therefore, it is particularly advantageous if the assembly is mounted in total and in a simple manner in the correct mutual assignment of the components.

In the following an embodiment of the invention will be explained in more detail with reference to the drawings. Show it :

Fig. 1 is a schematic side view of a sliding door according to the invention and

2 is a schematic plan view of the sliding door according to the invention from FIG. 1. In Fig. 1 and 2, a sliding door 1 according to the invention is shown schematically. Fig. 1 shows a side view of the sliding door, while Fig. 2 darsteift a plan view.

The sliding door 1 has a running rail 10, which is horizontally mounted on a door opening and a drive 13 leads, to which a door leaf 12 is suspended suspended. In the illustrated embodiment, two drives 13 are provided on the door leaf 12, of which only one is visible. The drives 13 are arranged mirror-inverted on the door leaf 12. The drives 13 have rollers 14, which are guided in a raceway 16 of the running rail 10 and roll there friction.

Above the track 16 of the running rail 10, a damper unit 20 is arranged with retraction function. At a defined position with respect to the damper unit 20, a limiting device 15, which limits the travel path of the door leaf 12, is further fastened in the running rail 10. In order to ensure the defined positioning of the limiting device 15 with respect to the damper unit 20 during assembly of the sliding door, the damper unit 20 and the limiting device 15 have mutually adapted positioning elements. In the embodiment shown in FIG. 1, a dowel pin 23 is provided on the limiting device 15 for this purpose, which engages in a bore 22 in the damper unit 20 which is adapted to the dowel pin 23. The positioning elements of the damper unit 20 and the limiting device 15 thus have a shape adapted to one another.

The damper unit 20 has an engaging part 17 into which a coupler 30 of the drive 13 can engage with a detent. For this purpose, the engaging part 17 has a recess 25, in which the coupler 30, which is formed in the illustrated embodiment as from the drive 13 upwardly projecting nose, can intervene. When moving the drive 13 in the direction of a EndsteÜung, which is indicated in Fig. 1 by a Pfeii corresponding, engages the coupler 30 in the engaging portion 17 of the damper unit 20 a. The damper unit 20 brakes the door flights! 12 first and then drives him into the EndsteÜung shown in Fig. 1. For this purpose, the damper unit 20 on a piston-cylinder unit, not shown, which causes a damping function and thus the braking of the door leaf, parallel to the piston-cylinder unit, the damper unit 20 has a spring which drives the door leaf 12 by its spring force in the end position.

In the end position, the drive 13 is struck on the limiting device 15, so that a first stop surface 15a of the limiting device 15 rests against a second stop surface 13a of the drive 13. The first stop surface 15a of the limiting device 15 is formed in the embodiment shown in FIG. 1 by a stop buffer 35, which may be formed for example as a rubber buffer.

The coupler 30 is arranged on the drive 13 at the rear end 18 in the direction of the end position. The coupler 30 is thus arranged on the side facing away from the second stop surface 13a of the drive 13 side of the drive 13, so that it is prevented by striking the drive 13 on the limiting device 15 to a deformation of the coupler 30 or the rear end 18th that carries the coupler 30 may come.

Thus, it can be ensured that a distance d between the second stop surface 13a on the drive 13 and the coupler 30 is fixed. The distance d corresponds to the distance D between the engaging part 17 and the damper unit 20 in a damper end position and the first stop surface 15a of the limiting device 15. The distances d and D extend in each case in the longitudinal direction of the running rail 10. The Därnpferendstellung is shown in FIG. 1 position of Därnpfereinheit 20, wherein in this damper end position, the damper unit 20 is not fully retracted. Such a construction prevents the forces generated when striking the drive 13 to the limiting device 15 must be absorbed by the damper unit 20, so that damage to the damper unit 20 is prevented. Since the distances d and D are predetermined by design and are immutable by the distance d are given by the dimensions of the drive and the distance D is determined by the defined positioning of the limiting device 15 to the Därnpfereinheit 20, it is ensured that the drive 13 basically only abuts against the limiting device 15.

The door leaf 12 can project beyond the drive 13 in the direction of the end position, so that in the end position the door leaf 12 is flush with the running rail 10. This is particularly advantageous when mounting the sliding door 1 according to the invention adjacent to a wall. The limiting device 15 cooperates with a part of the drive 13, which is arranged laterally of the door leaf 12, so that a part of the door leaf is moved in the direction of observation via the limiting device 15. Due to the compact design of the drive 13, it is possible that, although the door protrudes laterally for visual reasons, the roller 14 is still relatively close to a lateral edge 12a of the door leaf 12 is arranged, so that with a provision of two drives a large distance between the rollers 14 of the drives 13 is present, whereby an advantageous and stable guidance of the door leaf 12 is made possible.

As can be seen from Fig. 2, the engaging part 17 is formed as a fork. In the process of the drive 13 in the Endsteiiung while the engaging member 17 is initially in an initial position in which the recess 25 extends substantially in the longitudinal direction of the track rail. This is the result Recess 25 in a position that the coupler 30 can engage in the recess 25 during the process of the drive. During further movement of the drive 13 in the direction of the end position, the engaging part 17 is pivoted. For this purpose, the engaging part 17 is guided in the damper unit 20 in a slotted guide 40, which causes the pivoting of the engaging part 17.

The coupler 30 of the drive 13 abuts against the end part of the fork 17 a in the direction of the end position, so that a force is exerted by the drive 13 on the damper unit 20. The damper unit 20 now brakes the drive 13 by the damping function. In the further course of the travel of the drive 13 outweighs the clamping force of the present in the damper unit 20 spring, so that the engaging member 17 is pulled in the direction of the final division. The in the end position rear portion 17b of the engaging member 17 is now applied to the coupler 30 and exerts a force on the drive 13 so that it is pressed into the Endsteüung shown in Fig. 1 and 2. The Kuiissenführung 40 thereby causes the engaging member 17 remains in the pivoted position and the forces described can be transmitted.

Upon movement of the Türflugis 12 from the end position of the coupler 30 exerts a force on the rear end 17b of the engaging member 17, so that the spring of the damper unit 20 is tensioned. Through the slide guide 40, the engaging part 17 is then pivoted to the starting position in the further process of the drive 13, so that the Koppier 30 is released.

The construction according to the invention causes the drive 13 can be made very compact. Furthermore, the drive 13 can be arranged very close to a lateral edge 12a of the door leaf 12, so that when using two drives 13 on a door! 12, the drives 13 are very far apart and thus cause an advantageous guidance of the door leaf 12. The drive 13 may have a length that is less than that Length of the damper unit 20, In this case, the drive 13 is in the end position shown in the figures completely in the region of the running rail 10, in which the damper unit 20 is arranged. In other words, in the embodiment shown in the figures, the drive 13 is moved completely below the damper unit 20.

Of course, the damper unit 20 does not necessarily have to be arranged above the track 16 and thus above the drive 13. Of course, the damper unit 20 can also be arranged laterally to the drive 13, the coupler 30 then having to protrude laterally from the drive 13.

The damper unit 20 is arranged displaceably in the longitudinal direction of the running rail 10. A displacement of the damper unit 20 can basically be done with or without the limiting device 15. By providing the positioning elements, even when the damper unit 20 is displaced, it can basically be ensured that the limiting unit 15 is arranged at the correct position. The damper unit 20 can be fastened to the running rail 10, for example, via a groove in the running rail 10 and to the groove adapted to the groove.

The door leaves 12 of the sliding door according to the invention are designed, for example, as all-glass doors, the drive 13 being fastened to the door leaf 12 via a clamping connection.
