Description

The present invention relates to a sliding door system having at least one door leaf according to the preamble of claim 1.

Such sliding door systems are for example off DE 10 2016 202 774 A1 the applicant known.

In sliding door systems, which identify a damper unit with retraction function on the door, there is the fundamental problem that at a height adjustment of the door, in which the damper unit is secured to the top of the door, there is a height offset between a mounted in the guide rail damping coupler and the damper unit can, whereby a reliable function of the coupling between damper unit and damping coupler can not be ensured.

In DE 10 2016 202 774.3 this problem has been overcome by the damper unit is attached to a carriage, which is guided in the guide rail, wherein the height adjustment is carried out by the door is adjusted relative to the carriage. As a result, the damper unit is always guided independently of the set height of the door leaf in the same height in the guide rail, so that after assembly of the damping coupler always cooperates reliably with the damper unit.

Other solutions provide that the damping coupler has a greater vertical height, as the corresponding engaging part of the damper unit, so that even with a relative displacement of the damper unit and thus the engaging member relative to the damping coupler, a coupling of the damping coupler and the engaging part can take place. Such a solution is for example off DE 10 2009 005 441 the applicant known.

In such a solution, however, there is the problem that the damping coupler protrudes laterally from an arm and cooperates with an opened to the side engaging part of the damper unit. The guide rail must therefore be made relatively wide in order to accommodate damping coupler and damper unit can. Furthermore, an adjustment of damping coupler and damper unit to each other not or only to a small extent possible.

It is therefore an object of the present invention to provide a sliding door system of the type mentioned, in which the adjustment of damper unit and damping coupler is simplified to each other. Furthermore, if possible a compact design of the guide rail should be made possible.

The invention is defined by the features of claim 1.

The sliding door system according to the invention has at least one door leaf and a guide rail. The door is guided in the guide rail in one direction. On the door a damper unit is arranged with pull-in function. A damping coupler is attached to the guide rail, which engages with an engaging part of the damper unit latching. The damper unit slows down the door when moving into an end position and then drives it into the end position. The invention is characterized in that the damping coupler is arranged on a pivotably mounted lever, wherein the pivoting position of the lever is adjustable via an adjusting device. The invention thus advantageously allows the position of the damping coupler can be adjusted in a simple manner by the adjustment is adjusted. The damping coupler can be easily pivoted in a direction toward and away from the door leaf and the damper unit (relative to a position of the door leaf below the damping coupler). By providing the damping coupler on a pivotably mounted lever, wherein the pivoting position of the lever is adjustable via the adjusting device, the adjusting device can be arranged at a distance from the damping coupler, so that a pivoting of the lever and thus adjusting the damping coupler, for example, is also possible when a part of the damper unit is already below or next to the damping coupler. As a result, a particularly advantageous adjustment of the Dämpfungskopplers is possible.

Preferably, the lever is designed as a two-sided lever with a first lever arm, on which the damping coupler is arranged, and a second lever arm, on which the adjusting device is arranged. Due to the design of the lever as a two-sided lever with the damping coupler on a first lever arm and the adjusting device on a second lever arm on the one hand ensures that the adjustment is relatively far away from the damping coupler, so that a comfortable adjustment can be made, even if the damper unit of Door leaf is already below or near the Dämpfungskopplers. Furthermore, it can be achieved that is pivoted relatively far by an already small adjustment by means of the adjustment of the damping coupler by the adjusting device is arranged closer to the swivel bearing of the lever as the damping coupler.

It is preferably provided that the damper unit is arranged on the upper side of the door leaf. In such an arrangement, in which the guide rail guides the upper side of the door leaf, the damper unit can advantageously be arranged within the guide rail and thus be concealed by the guide rail, whereby the sliding door system is designed aesthetically pleasing. The damper unit can be arranged in particular on the upper end face of the door leaf. The arrangement of the damper unit at the top of the door leaf also has the advantage that it is largely safe from the user's access in normal use, so that it can not come to unwanted adjustments of the lever.

It is preferably provided that the lever is pivotable in a vertical plane and the engaging part of the damper unit is directed upward. The snubber is thus also in a vertical plane, i. H. from bottom to top or vice versa movable. The upwardly directed engaging part is arranged such that it is open at the top. In the latching state between the damping coupler and the engaging part, the engaging part thus comprises the damping coupler from below. In a release position, the attacking part is also opened laterally. The door leaf moves with the damper unit, wherein the engaging part is arranged in the release position, toward the damping coupler. In this case, the damping coupler set via the lever and the engaging part are at a common effective height. The damping coupler presses against the engaging part and releases it from the triggering position, so that the engaging part engages around the damping coupler from below. In this way, a secure engagement between the engaging part and damping coupler is made possible, on the one hand the retraction function of the damper unit is ensured and on the other hand, when moving the door leaf from the end position, the damper unit is returned to the triggering position of the engaging part.

In a preferred embodiment of the invention it is provided that the lever is formed by two parallel arranged sub-arms, wherein the damping coupler is formed by a rod connecting the sub-arms. Such a configuration of the damping coupler and the lever enables a stable configuration of the lever arm and damping coupler, which, however, have a low cost of materials. In addition, the damping coupler formed as a rod is guided at both ends thereof, so that deformation of the damping coupler due to the load by the engagement with the engaging member is prevented.

It is preferably provided that the adjusting device is designed as an adjusting screw. By adjusting the adjustment can be done in a simple manner and infinitely.

The adjusting device preferably has an actuating device which can be operated from below. This can be formed for example by a screw head of the adjusting screw. By operating the bottom of the actuator, the damping coupler can be operated in an advantageous manner when it is mounted on a guide rail leading to the top of the door, even if in this way the lever is arranged at a relatively high altitude.

In a preferred embodiment of the sliding door system, this has a running rail, which is designed as a bottom rail, wherein on the lower side of the door a carriage is arranged, which is guided on the bottom rail, and wherein the guide rail guides the top of the door leaf. In such an embodiment, the weight of the door leaf is supported by the bottom rail. The guide rail thus assumes only a lateral guidance of the door leaf. In such an embodiment of the sliding door system according to the invention, the inventive arrangement of Dämpfungskopplers has been found to be particularly advantageous on a pivoting lever, since the guide rail for guiding the door must have a relatively narrow path, the arranged on a lever damping coupler due to its relatively low space requirement in advantageously in the path of the guide rail can be arranged.

Preferably, it is provided that a limitation of the path of the door limiting device together with the damping coupler forms a structural unit. Such a configuration has the particular advantage that the distance between the limiting device and the damping coupler is already predetermined, so that complex adjustments during installation of the sliding door system are not necessary. Furthermore, it is ensured by specifying the distance between the limiting device and the damping coupler that the door at most with a very low speed abuts against the limiting device, so that damage to the door is avoided. Since the door can basically be designed as a glass door leaf, such a configuration is of particular advantage.

Preferably, it is provided that the damper unit is arranged on an L-shaped plate, wherein a first leg of the plate on the upper end face of the door leaf and a second leg of the plate is arranged on the end face directed in the direction of the end face of the door leaf. Preferably, the first leg of the plate is attached to the upper end face, for example glued. About the L-shaped plate, the damper unit can be arranged in an advantageous manner to the door leaf. The second leg may, for example, interact with the limiting device limiting the travel of the door leaf and, for example, have a rubber buffer as a stop. The second leg protects the end face of the door leaf directed in the direction of the end position so that damage to the door leaf can not occur, for example, in the case of an embodiment of the door leaf made of glass. Furthermore, the height adjustment of the damping coupler can be controlled over the length of the second leg. For this purpose, for example, the door is moved to a position in which the damping coupler is aligned with the second leg of the plate or a small distance between these two parts. By measuring the vertical distance between the lower end of the second leg and the damping coupler or checking this distance by means of a gauge, the set height of the damping coupler can be checked. This makes a particularly convenient and advantageous adjustment of the Damping Coupler possible.

It is preferably provided that the second leg tapers towards its free end, wherein the tapered portion has a predetermined breaking point. As a result, the second leg can be made relatively long, which is advantageous in height adjustment and checking the height of the damping coupler, since the second leg extends far out of the guide rail. After the height adjustment and the control of the set height of the damping coupler, the end of the second leg, which tapers towards the free end, can be broken off by the predetermined breaking point, so that the latter can no longer visually disturb the observer. In particular, it can be provided that the second leg is in its then so shortened form completely within the guide rail. As a result, an aesthetically pleasing sliding door system can be created.

In the end position of the door leaf, the plate rests against the limiting device via the second limb. This can be done for example via a arranged on the second leg stop buffer.

Preferably, the sliding door system has at least one further door leaf, wherein the further door leaf is drivable over the door leaf for carrying out a rectified movement. The sliding door system according to the invention can thus be a multi-leaf sliding door system. It is provided that the guide rail has a plurality of grooves in each of which one of the door wings is guided. Preferably, the sliding door system with a plurality of door leaves is guided on the bottom side over the running rail, wherein the guide rail guides the upper side of the door leaves. The at least one further door leaf of the sliding door system may have a further damper unit with retraction function, wherein a further damping coupler is attached to the guide rail, which engages detent with the engaging portion of the further damper unit, wherein the further damper unit initially decelerates the further door when moving into an end position and then drives into the end position. The invention thus provides that the further door leaf or any other door leaf is autonomously braked via a damper unit with retraction function and the end position is driven. Thus, it is prevented that the first door leaf, which drives the further or the further door leaves, has to accomplish a braking of all doors.

In a particularly preferred embodiment of the invention it is provided that the damping coupler for the door leaf and the further damping coupler for the further door leaf are arranged in a direction transverse to the running direction side by side. In other words, the door leaf and the further door leaf are in their final position exactly next to each other. Of course, such an arrangement can also be made for each further door leaf. Such an arrangement is preferably provided at an end position in which the sliding door system is arranged in an open position.

Preferably, it is provided that the door has a second damper unit with retraction function and that a second damping coupler is attached to the guide rail, which engages detent with an engaging part of the second damper unit, wherein the second damper unit first decelerates the door when moving to a second end position and then drives in the second end position and that the further door has a second further damper unit with retraction function, and that a second further damping coupler is attached to the guide rail, which engages latching with an engaging part of the second further damper unit, wherein the second further damper unit the other door at First decelerates method in a second end position and then drives into the second end position, wherein the second damping coupler of the door leaf and the second further damping coupler of the further door leaf in egg ner direction are arranged transversely to the running direction side by side. In other words: the door leaf and the further door leaf each have a second damper unit, which decelerates the corresponding door during the process in a second end position. The second damping couplers are also arranged such that even in the second end position, the door leaves are arranged exactly next to each other. The second end position of the door is thus a second open position of the sliding door system. Of course, each further door leaf may have a corresponding second damper unit and a corresponding second damping coupler, which is arranged next to the other second damping couplers. The sliding door system according to the invention is therefore particularly suitable for sliding door system variants in which the door leaves are coupled to execute a rectified movement, but can also be decoupled. Such sliding door systems, which are used for example for terrace glazing, are thus movable in the manner of a conventional telescopic sliding door in a closed position. From the closed position, the door leaves can be moved coupled either in the direction of the first end position, so that the sliding door system is in a first open position or coupled to be moved in the direction of the second end position, so that the sliding door system is in the second open position. When decoupling the door leaves they can be moved individually in the first or second end position.

The further attenuation coupler or the further attenuation couplers, the second attenuation coupler and the second further attenuation coupler or the second further attenuation couplers preferably form, just like the attenuation coupler, a structural unit with a limiting device which delimits the travel path of the respective door leaf or further door leaf. Thus, in the movement of each door leaf in both the first and the second end position ensures that the respective damping coupler reliably cooperates with the respective damper unit. In the sliding door system according to the invention, all damper units can be designed, for example, as a spring damper system. When moving into an end position can be provided that in the end position of the respective door the damper unit is not fully retracted, so that on the one hand a beating in the damper unit, which could lead to damage to the damper unit is prevented and on the other hand by the spring force of Damper spring unit of the door is held in the end position.

In 1 is a sliding door system according to the invention 1 shown schematically in a page representation. The sliding door system 1 consists of several door leaves 3 , 3a, 3b, the in 1 in the closed position of the sliding door system 1 are shown. The doors 3 . 3a . 3b are coupled and fanned out in the closed position. The Indian 1 the leftmost door 3a is in a first end position 100 and in the 1 rightmost door wings 3b is in a second end position 102 , To open the sliding door system 1 The door leaves can be moved in both directions. For example, the door shown on the far right 3b towards the first end position 100 be moved and thereby drives the other door leaves 3 on. In this first opening position are all the doors 3 . 3a . 3b in the first end position 100 , It is also possible that the door leftmost shown 3a towards the second end position 102 is moved, with the door 3a the remaining door leaves 3 drives and in the resulting second opening position all the doors 3 . 3a . 3b in the second end position 102 are located. Further, the doors are 3 . 3a . 3b decoupled from each other so that the door leaves 3 . 3a . 3b individually in the first end position 100 or second end position 102 can be moved. As well as out 2 The door leaves are 3 . 3a . 3b at its lower end on a running rail designed as a bottom rail 5 guided. For this purpose, the door wings 3 . 3a . 3b each management facilities 7 on, on profile rails 5a the track 5 are guided. The track 5 takes the weight of the door 3 . 3a . 3b on. At the top are the doors 3 . 3a . 3b through a guide rail 9 guided. The guide rail 9 offers the door wings a side guide. For this purpose, the guide rail 9 several each a guideway forming grooves 11 on, in which the top of the door leaves 3 . 3a . 3b are introduced.

The doors 3 . 3a . 3b each have a damper unit 13 with pull-in function on. The arrangement of the damper unit 13 on the door wings 3 . 3a . 3b is in the 3A . 3B by way of example with reference to a door leaf 3a described in the final position 100 is moved. At the top of the door leaf 3a is a damper unit 13 arranged with pull-in function. This has an attacking part 15 on. The attacking part 15 engages in the in the 3A and 3B shown positions of the door leaf 3a latching with a damping coupler 17 together. The damping coupler 17 is on a pivotally mounted lever 19 arranged. The lever 19 is at one the path of the door leaf 3a limiting limiting device 21 arranged so that the limiting device 21 and the snubber coupler 17 together with the lever 19 a structural unit 23 form. The construction unit 23 is in a T-shaped groove 25 the guide rail 9 via a mounting plate adapted to the groove 28 attached, the unit 23 in the longitudinal direction of the guide rail can be attached to any position.

The lever 19 is designed as a two-sided lever with a first lever arm 19a and a second lever arm 19b who in 3A is shown schematically hidden. The lever 19 has an adjustment 27 on, about the pivoting position of the lever 19 and thus the height of the Damping Coupler 17 is adjustable. The adjusting device 27 is on the second lever arm 19b arranged and formed for example as an adjusting screw. How out 3A it can be seen, is the adjustment 27 much closer to a swivel camp 29 of the lever 19 as the damping coupler 17 , so that already slight adjustments of the adjustment 27 due to the leverage to a much larger height adjustment of the Dämpfungskopplers 17 to lead.

In 3A is the door 3a shown in a position in which the damping coupler 17 to the attacking part 15 attacks, the attacking part 15 has just been moved out of an attack position. The door leaf 3a moves in the direction of the end position 100 as shown by the arrow. Then the attacking part surrounds 15 the damping coupler 17 , like out 3B is apparent. Due to the damping effect of the damper unit 13 will be the door 3a first decelerated and then by due to the feed function, which can be done for example by a spring means, not shown, in the direction of the end position 100 drawn.

The damper unit 13 is at an upper end face 31 of the door leaf 3a attached. For this purpose, the damper unit 13 on an L-shaped plate 33 attached, with a first leg 33a the plate 33 at the upper end face 31 of the door leaf 3a is arranged and a second leg 33b the plate 33 at one in the direction of the end position 100 directed face 35 of the door leaf 3a is arranged. The second leg 33b the plate 33 lies in the end position of the door leaf over a stop buffer 37 on the limiting device 21 on, like out 3B is apparent. Through the second leg 33b and the stop buffer 37 This prevents the door from falling 3a directly against the limiting device 21 abuts, so that, for example, in an embodiment of the door leaf 3a made of glass Damage to the door leaf 3a be avoided.

For a reliable connection between damping coupler 17 and attacking part 15 need damping couplers 17 and attacking part 15 have a height adapted to each other. The height of the Damping Coupler 17 can be via the adjustment 27 to the height position of the attacking part 15 to adjust. The adjustment of the height of the Damping Coupler 17 However, it is relatively difficult because the damper unit 13 and the snubber coupler 17 in the guide rail 9 located only accessible from below. In the sliding door system according to the invention 1 can be done with the help of the second leg 33b the plate 33 a simplified height control of the Damping Coupler 17 carry out. This is the door 3a in an in 4 shown height control position procedure. In this position is the door leaf 3a with its forward facing face 35 just before the damping coupler 17 , By measuring the vertical distance between the snubber coupler 17 and the lower end of the second leg 33b the plate 33 can be the height of the Damping Coupler 17 check. This can be done by classical measuring or, as in 4 is shown about a lesson 104 respectively.

Because the door 3a in the height control position beyond a relatively large horizontal distance to the adjustment 27 has, the height adjustment of the Dämpfungskopplers 17 over the adjusting device 27 be easily accessible in an advantageous manner. For this purpose, the adjustment 27 a bottom-operated actuator 27a on, which may be a screw head, for example. In the case of FIGS. illustrated embodiment is the lever 19 pivotable in a vertical plane and the engaging part 15 the damper unit is directed upwards. The damping coupler 17 abuts while moving the door leaf 3a in the direction of the end position against the attacking part 15 that is in the attack position. In 4 is the attacking part 15 shown in the attack position. Subsequently, the braking and the entrainment of the door wing done 3a in the manner described above.

The second leg 33b tapers to its free end, with the tapered section 33c a breaking point 33d having. How out 2 is apparent, is the tapered portion of the second leg 33b visible from the outside, as this from the guide rail 9 protrudes. This is for height control of the Damping Coupler 17 advantageous because the measuring point at the lower end of the second leg 33b is visible to the user in an advantageous manner.

After the height adjustment, which usually has to be done only once during assembly, the tapered section 33c be annoying to the viewer, so over the breaking point 33d after the height adjustment the tapered section 33c can be removed by canceling.

Like from the 2 and 5 As can be seen, the other doors can 3 , 3b in each case a corresponding structural unit 23 from damping coupler 17 and limiting device 21 respectively. At the other doors 3 , 3b is then arranged in each case a further damper unit in a comparable manner as in the 3A and 3B in relation to the door leaf 3a is shown.

The other doors 3 , 3b are then in a process in the first end position 100 also braked and in the final position 100 driven.

How out 5 shows, are the building units 23 for the door leaves 3 . 3a . 3b arranged directly next to each other, so that in the first end position 100 the door leaves 3 . 3a . 3b are exactly next to each other. The doors 3 . 3a . 3b However, also not shown second damper units may have, each at the other end of the door 3 . 3a . 3b are arranged and with second damping couplers 17a interact. The second damping coupler 17a are in the second end position 102 on building units 23a arranged the building units 23 the damping coupler 17 same in the first end position.

The damping couplers 17a are in the second end position 102 also arranged side by side, leaving the door wings 3 . 3a . 3b in the second end position 102 are also exactly next to each other.

How out 5 can be seen, are the levers 19 in each case by two parallel arranged sub-arms 19c formed, wherein the damping coupler 17 through one of the partial arms 19c connecting rod is formed. This allows on the one hand a very light, yet stable construction and on the other hand prevents the damping coupler 17 due to the interaction with the attacking part 15 can be deformed.

The sliding door system according to the invention 1 is in the Fign. shown as a multi-leaf sliding door. Basically, the sliding door system 1 However, only consist of a single-leaf sliding door.

In the case of FIGS. illustrated embodiment, the lever 19 pivoted in a vertical plane and the attacking part 15 is directed upwards. In principle, there is also the possibility that the lever 19 is pivotable in a horizontal plane, wherein the engaging part 15 directed to one side.
