Description

The present invention relates to a sliding door system according to the preamble of claim 1.

Such sliding door systems are used, for example, for terrace glazing. When moving into the closed position, a door leaf of the sliding door system is pushed with its front edge into the cavity of the frame element. This avoids a gap between the frame element and the door leaf in the closed position of the door leaf, so that a relatively wind-tight closing position can be created.

The running rails of such door leaves are either designed as a floor rail on the bottom side or the door leaf is suspended in a running rail arranged at the top.

Particularly when the door leaf is made of glass, it is difficult to create an aesthetically pleasing locking device with which the door leaf can be locked, for example to avoid opening the door leaf from the outside. Known solutions for multi-leaf sliding door systems consist of providing a locking of the door leaves against each other, the locking usually being carried out in a running profile that interacts with the running rail. The locking device is therefore located either on the bottom or in the upper area of the door leaf, so that operation is relatively complex.

In addition, the lock is visible to the viewer when the door leaves are in the closed position, so that the locking device can have an aesthetically disturbing effect on the viewer.

Out of US 2017/0254125 A1 a sliding door system according to the preamble of claim 1 is known. US 4,676,537 shows a sliding door system with a Door post and a door leaf, the door leaf having a rotatably mounted latch which engages in the door post in a closed position. FR 2 704 344 shows a security gate with a gate post fixed to the ground and a gate, the gate post having an automatic locking device with a latch and a motor to mechanically lock the gate.

It is therefore the object of the present invention to further develop the known sliding door system in such a way that an aesthetically pleasing lock device is created that can be operated with as little effort as 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 with a guide device and a running rail, the door leaf being guided in a running direction via the guide device through the running rail. A vertically arranged frame element partially surrounds a cavity, the frame element having an opening to the cavity in the direction of the door leaf. In a closed position, the door leaf partially extends through the opening into the cavity. The invention is characterized in that in the cavity of the frame element a lock device with a locking device having a latch and a latch receptacle is arranged on the door leaf, wherein in the closed position of the door leaf the latch engages in the latch receptacle for locking the door leaf in a locking position.

The invention therefore provides that the lock device is arranged in the frame element so as to be largely concealed from the viewer. As a result, the lock device is not aesthetically disturbing for the viewer. In contrast to previously known sliding door systems, which provide for locking several door leaves against each other, the present invention can also be used for a sliding door system with only one door leaf, since the door leaf is locked with the frame element.

The latch receptacle is preferably arranged on the front of the door in the direction of travel of the door and protrudes from the front of the door.

According to the invention it is provided that the bolt receptacle is arranged on an end face of the door leaf that is directed forward in the running direction and protrudes in the direction of the frame element. This makes the construction simple Sliding door system possible because the bolt receptacle is relatively freely accessible to interact with the bolt.

It is preferably provided that the latch is movable in a vertical direction from the locking position into an unlocking position, the latch receptacle having a latch receiving opening which is directed at least upwards or downwards. In other words: The latch can be moved in a vertical direction and engages the latch receptacle from above or below. As a result, the lock device and the bolt receptacle can be designed to be relatively compact, so that the size of the frame element can be kept relatively small.

The locking device preferably has a spring device which biases the locking bar towards the locking position. As a result, the latch can only be unlocked against the spring force of the spring device, so that the locking device cannot be unintentionally unlocked.

It can be provided that the latch has an oblique insertion surface that faces towards the door leaf. When the latch is arranged in the locking position, the latch receptacle can push the latch towards its unlocking position by means of the insertion surface, so that the door leaf can be moved completely into the closed position even with a latch in the locking position. In an embodiment of the locking device with the spring device prestressing the locking lock, a snapping function of the locking lock into the locking receptacle is also possible via the oblique insertion surface.

It is preferably provided that the lock device has an actuating device which has a traction means connected to the bolt, the traction means being arranged in the cavity of the frame element. The actuation device, which has a traction means, can be used to enable the bolt to be actuated at any height of the frame element, so that convenient actuation of the lock device is also possible if it is in an upper or lower position lower section of the frame element is arranged. Due to the arrangement of the traction means in the frame element, the traction means is also largely hidden from the viewer.

It is preferably provided that the traction means is designed as a cable pull. As a result, the actuating device can be provided in a structurally simple manner.

It can be provided that the actuating device penetrates the frame element towards an actuating side, the actuating device having an actuating device which is attached to the traction means, the actuating device being at least partially arranged outside the frame element. The actuating device can be, for example, a handle button. The user of the sliding door system can use the actuating device to operate the actuating device and thus the lock device in an advantageous manner. Because the actuating device penetrates the frame element to an actuating side, the actuation of the actuating device and thus the lock device from the actuating side is possible in a convenient manner.

In an embodiment of the locking device with a spring device that biases the locking bolt in the direction of the locking position, the spring device also ensures that the dead weight of the actuating device or the actuating device does not lead to an unintentional unlocking of the locking bolt, but rather the locking bolt in the Locking position is held.

It is preferably provided that the actuating device, preferably the actuating device, can be locked in a pulling position to hold the bolt in the unlocking position. In other words: The user of the sliding door system can lock the lock device in the unlocking position of the bolt via the actuating device, so that the door leaf moves freely into and out of the closed position can be. After releasing the actuating device, the latch is moved back into the locking position, for example by means of the spring device, so that the door leaf is locked or, for example, when the door leaf is closed, the latch snaps into the latch receptacle.

It is preferably provided that the locking device is arranged in a lower end region of the frame element. The lower end region can, for example, comprise a section which extends from the lower end of the frame element up to 10% of the length of the frame element. By arranging the locking device in a lower end region of the frame element, the locking device can be mounted in a simple manner. In an embodiment of the sliding door system with a running rail as a bottom rail, the locking device can also cooperate, for example, with a locking receptacle which is arranged on the guide device guided on the running rail.

It is preferably provided that the frame element is designed in two parts and has a frame profile and a lock profile that accommodates the locking device, the lock profile being connected to the frame profile. As a result, the frame element of the sliding door system according to the invention can be adapted in a particularly simple manner to the conditions at the installation location of the sliding door system, since the frame profile can be designed as a profile that can be freely cut to length and - after adapting the frame profile to the installation location - the lock profile can be connected to the frame profile.

It is preferably provided that the lock profile is arranged between the frame profile and the running rail. The frame profile can thus be connected to the running rail using the lock profile. The latch receptacle can be designed, for example, as an eyelet.

It is preferably provided that the running rail is a floor rail and the guide device has at least one carriage arranged on the lower side of the door leaf, which is guided on the floor rail.

It can be provided that the bolt receptacle is arranged on the carriage. The bolt receptacle is preferably arranged on the end face of the carriage that is directed forward in the running direction. The arrangement of the latch receptacle on the carriage is particularly advantageous in an embodiment of the sliding door system with a glass door leaf, since the latch receptacle can thus be arranged in an advantageous manner on the door leaf.

The design of a sliding door system with a running rail as a bottom rail advantageously enables the design of the sliding door system for terrace glazing, since the weight of the door leaf or several door leaves is supported by the bottom rail. Therefore, only a simple guide profile is required to guide the upper end of the door leaf or leaves. To support the guide profile, only its own weight has to be carried, so that it can be easily attached to a ceiling, for example. When supporting the guide profile on the ground, for example, only stands are necessary at the respective end of the guide profile. With such designs, large opening widths of the sliding door system are possible.

It is preferably provided that the frame element and the running rail have mutually adapted guide elements, via which the frame element can be arranged in a defined position relative to the running rail. This ensures that the bolt is at a previously defined height and can interact with the bolt holder on the door leaf. Furthermore, the defined positioning of the frame element relative to the running rail ensures that the frame element is in alignment with the door leaf, so that the door leaf can be partially pushed through the opening into the cavity formed by the frame element.

It is preferably provided that the guide elements are formed by a profile rail of the running rail that interacts with the guide device of the door leaf and a recess in the frame element. In other words: The frame element is placed using a recess on the profile rail of the running rail, on which the door leaf is also guided by means of the guide device. This ensures that the frame element is aligned with the door leaf. When the running rail is designed as a floor rail, the profile rail forms a running surface for a carriage of the guide device. The recess is preferably arranged in the lock profile.

In a preferred embodiment of the sliding door system, the running rail is designed as a floor rail with a profile rail on which a carriage of the guide device is guided, the latch acceptance being arranged on the carriage on the end face directed forward in the direction of travel. Furthermore, in this preferred embodiment, the lock profile is placed on the profile rail with a recess. This ensures that the locking device and locking device are guided very precisely, since the locking device and locking device are arranged in close proximity to the profile rail forming a guide element. This prevents inaccurate installation situations from occurring due to minor deformations of the frame element.

It is preferably provided that the frame element has a groove extending in the longitudinal direction of the frame element. The groove can be a T-slot, for example.

The groove offers the possibility of attaching the frame element to its surroundings or of attaching attachments for the frame element to the frame element.

It is preferably provided that the actuating device has a guide device for the traction means, the Guide device is attached in the groove. This can be done, for example, using a sliding block. The guide device can be, for example, a deflection device.

It is preferably provided that the groove is arranged in the frame profile, with the lock profile being attachable to the frame profile via the groove. This can be done, for example, using a sliding block. In this way, a particularly advantageous attachment of the lock profile to the frame profile is possible.

The sliding door system according to the invention preferably has at least one further door leaf, wherein the further door leaf can be driven via the door leaf to carry out a movement in the same direction. The sliding door system can therefore be designed as a so-called telescopic sliding door system. In an embodiment of the sliding door system with several door leaves, it can also be provided that in the closed position of the sliding door system, the two outer door leaves each interact with a frame profile according to the invention and can each be locked via a corresponding lock device. Both frame elements and lock devices can have the aforementioned features.

It is preferably provided that the sliding door system has a damper device with a retraction function, the damper device first braking the door leaf when closing and then driving it towards the closed position and with a limiting device which limits the travel of the door leaf, the damper device pushing the door leaf against the door leaf to reach the closed position Limiting device drives. The invention therefore provides that the door leaf is dampened when it moves towards the closed position, so that the door leaf hits too hard is avoided. This is particularly advantageous when the door leaf is designed as a glass door leaf, as damage is avoided. When designing the Sliding door system with several door leaves, a damper device can be provided for each door leaf.

In a preferred embodiment of the invention it is provided that the damper device holds the door leaf in contact with the limiting device in order to maintain the end position during a locking process. This ensures that the locking process can take place in a reliable manner. It can also be provided that the damper device is designed as a spring damper system, wherein the spring force of the spring damper system present at the time the bolt receptacle abuts against the bolt arranged in its locking position is greater than the force required for moving the bolt against the preload force of the Spring device of the latch is necessary. Of course, the spring force at this point is also sufficient to move the damper further. This makes it possible for the spring damper system to move the door leaf towards its closed position, whereby when the bolt is arranged in a locking position, it is displaced against the biasing force of the spring of the bolt and the bolt can snap into the bolt receptacle. The spring damper system is therefore designed in such a way that it can move the door leaf into the closed position and the force necessary for the locking device to snap into place is present in sufficient quantities.

The door leaf or the door leaves are preferably designed as glass door leaves.

The door leaves 3, 3a, 3b are guided on a running rail 5 arranged on the floor via a guide device 7. The upper end of the door leaves 3,3a,3b is guided over a guide rail 9.

The guide rail 9 and the running rail 5 are connected via a frame element 11 and another frame element 13.

The in Fig. 1 The outer door leaf 3a shown on the far left, in the closed position of the door leaf shown, is partially inserted into a cavity 11a which is partially surrounded by the frame element 11.

In Fig. 2 a detailed representation of the guide device of the door leaf 3a and the frame element 11 is shown schematically. The running rail 5 has several profile rails 15. The door leaf 3a is guided on one of the profile rails 15 by means of the guide device 7. For this purpose, the guide device consists of a carriage 17 and a guide profile 19, which is connected to the carriage 17. The profile rail 15 guides the guide device 7 and thus the door leaf 3a in a running direction. On the end face 17a facing the frame element 11 in the running direction A latch receptacle 21 is arranged on the carriage, which protrudes towards the frame element. The latch receptacle 21 is designed as an eyelet.

The frame element 11 consists of a frame profile 23 and a lock profile 25. How best Fig. 3 As can be seen, a lock device 27 with a locking device 29 is arranged in the lock profile 25. The locking device 29 has a locking bar 31 which engages in the locking receptacle 21 in the closed position of the door leaf 3a.

The latch 31 is movable in a vertical direction from a locking position to an unlocking position. The latch receptacle has a latch receiving opening 21a, which is open upwards, so that the latch 31 can engage into the latch receptacle 21 from above.

The locking device 29 also has a spring device 33 which biases the locking bar 31 in the direction of the locking position.

At its lower end, the latch 31 has an oblique insertion surface 31a, which faces towards the door leaf 3a. When the door leaf 3a is moved into its closed position, the latch receptacle 21 presses against the inclined insertion surface 31a and the latch 31 is pushed towards the unlocking position before it then snaps into the latch receptacle 21. How out Fig. 2 As can be seen, the lock profile 25 and the running rail 5 have mutually adapted guide elements, which are formed by a recess 35 in the lock profile 25 and the profile rail 15 which interacts with the guide device 7. The lock profile 25 and thus the frame element 11 is placed on the profile rail 15 by means of the recess 35. This ensures that the lock profile 25 and thus the lock device 27 is arranged in a correct position, so that the bolt 31 is positioned at the correct height in order to cooperate with the bolt receptacle 21, and the lock profile 25 and thus the frame element 11 is arranged in a position aligned with the door leaf 3a. This ensures that on the one hand, the lock device works reliably and, moreover, the door leaf 3a can be inserted into the cavity 11a.

The lock device 27 has an actuating device 37, which consists of a cable 39 and an actuating device 41 arranged at the end of the cable 39. The cable pull 39, which is the best Fig. 4 can be seen, is connected to the upper end of the bolt 31. The cable pull 39 is guided in the frame element 11 and penetrates the frame element 11 to an actuation side 100. A tensile force can be exerted on the cable 39 and thus on the latch 31 via the actuating device 41, so that the latch can be pulled from its locking position into its unlocking position.

The actuating device 41 also has a locking device 43, by means of which the actuating device can be locked in a pulling position to hold the bolt 31 in the unlocking position. At the in Fig. 4 In the exemplary embodiment shown, the actuating device 41, which can be designed as a handle button, is pulled and rotated to lock it.

In Fig. 5 a guide device of the actuating device 37 designed as a deflection device 45 is shown, which deflects the cable pull 39 and leads it in the direction of the actuating device 41. How out Fig. 5 As can be seen, the frame profile 23 of the frame element 11 has a groove 47 which extends in the longitudinal direction of the frame element 11 and is designed as a T-slot. The deflection device 45 can be fastened into the groove 47 by means of a sliding block 49. Furthermore, the lock profile 25 is also connected to the frame profile 23 via a sliding block and can be attached to it.

The door leaf 3a can first be braked when closing by means of a damper device (not shown) with a retraction function and then closed Be driven towards the closed position. A limiting device 51 is provided, which limits the travel of the door leaf, with the damping device driving the door leaf against the limiting device 51 to reach the closed position. The damper device is designed as a spring damper system, with the damper device holding the door leaf in contact with the limiting device 51 after reaching the closed position, so that a locking process can take place in an advantageous manner.

The spring of the damping system is designed in such a way that it has sufficient force to move the damper of the spring damper system, to move the door leaf 3a in the direction of the closed position and to allow the latch 31 to snap into the latch receptacle 21 against the biasing force of the spring device 33 .

In the exemplary embodiments shown, only the lock device 27 is shown in the frame element 11 in order to cooperate with the door leaf 3a. In principle, it is also possible that the second outer door leaf 3b, which is in Fig. 1 is shown on the far right, can also be locked via a lock device arranged in the further frame element 13, which has the same structure as the lock device 27. In this exemplary embodiment, the door leaf 3b also has a corresponding latch receptacle on the side facing the further frame element 13.
