SLIDING DOOR

Abstract

A sliding door includes a bar that is movable in the closing and opening direction of a door leaf the sliding door. When the sliding door is in a closed state, the door separates a first space from a second space. A door frame in which the door is mounted has a bar catch, wherein the bar engages in the bar catch when the door leaf is in the closed state. The engagement can be released by movement of the door leaf, and therefore movement of the bar, in the direction of the normal of the door leaf plane.

Description

DETAILED DESCRIPTION

[0024] FIG. 1 shows a sliding door 2. The sliding door 2 comprises a door frame 12, which comprises wall elements. A door opening 4 is recessed within these wall elements. The sliding door 2 furthermore comprises at least one door leaf 6, which is movable in a closing or opening direction SR shown according to FIG. 1. The door opening 4 and the door frame 12 are delimited at their respective lower ends by a floor 5. The sliding door 2 is shown in a partially open position, so that the door leaf 6 is concealed in part by the door frame 12. Accordingly, the edges of the door leaf covered by the door frame 12 are shown by dashed lines. In addition to a plurality of other components (not shown) of the sliding door, a locking device 8, 10 of the sliding door 2 is indicated. The locking device 8, 10 comprises a bar 8 and a bar catch 10. The bar 8 can be arranged above the door opening 4 with the door leaf 6. Alternatively, the bar 8 can be arranged at the lower end of the door leaf 6 or between the upper and lower ends. In a corresponding manner, the bar catch 10 is arranged at the door frame 12, in order to be able to interact with the bar 8 when the door leaf 6 is in the closed position.

[0025] FIG. 2 shows a horizontal section of an exemplary sliding door 2 in its closed position. The door leaf of the sliding door 2 is in its locked position. Regarding structural features of the embodiment shown in FIG. 2, reference is made to the description of the figures in the international application PCT/EP2020/055411. The difference that is decisive in FIG. 2 in comparison with this prior international application is the locking device 8, 10. The sliding door has a support frame 9, two door leaves 6, 6′, control arms 30.1, 30.2, 30.3′, 30.4′, and a door frame 12, and these elements interact in the manner described according to PCT/EP2020/055411.

[0026] Furthermore, the exemplary sliding door comprises a locking device 8, 10, 10′, wherein the bar 8 can be fixed to the support frame 9 and can interact with bar catches 10, 10′. The bar 8 and the bar catches 10, 10′ are arranged at the same height, wherein the bar 8 is arranged between the bar catches 10, 10′ when the sliding door 2 is in the closed position. Consequently, it is possible for the bar 8 to be able to be fixed in advance in two different positions, so that the bar 8 can interact with one of these bar catches 10, 10′ to lock the sliding door. If necessary, during installation of the sliding door, the bar 8 can be repositioned by rotating 180° about an axis arranged parallel to the closing or opening direction SR, so that the latch 8 engages in the second bar catch 10′ instead of the first bar catch 10 when the sliding door 2 is in the locked position.

[0027] Alternatively, the second bar catch 10′, with which second bar catch 10′ the bar 8 is not engaged when the sliding door 2 is in the locked position, can be replaced by any element of the door frame 12. Furthermore alternatively, the second bar catch 10′ can be omitted.

[0028] FIG. 3A shows a detail A of FIG. 2. The bar 8 has a recess 20 which, when the sliding door 2 is in the closed position, latches into the bar catch 10 which causes the sliding door 2 to lock. In order to support the latching of the bar 8 into the bar catch 10, a spring element 22 can interact with a component 10′ of the door frame on the opposite side of the recess 20, so that the bar 8 interacts with the recess 20 of the bar catch 10 in such a way that the sliding door is in its locked position. If necessary, this component 10′ can be formed by a second bar catch 10′.

[0029] The bar 8 can be detachably fixed to the support frame 9 at a surface 19 in such a way that the arrangement of the bar 8 can be changed by rotating 180° about the axis arranged parallel to the closing or opening direction. Accordingly, the recess 20 can also interact with the second bar catch 10′.

[0030] For the purpose of locking when closing the sliding door, the bar 8 can have a chamfer on its front edge 11 which, when an electric drive only acts in the closing direction S1, causes the bar 8 to be deflected by the bar catch 10 and consequently, when the sliding door is completely closed, is transferred to its locked position by the bar 8 snapping back.

[0031] By means of a force P1 acting on the support frame 9, which acts substantially in the direction of the normal of the door leaf plane, the lock is releasable, that is to say, the recess 20 of the bar 8 does not interact with the bar catch 10 when the bar 8 is displaced from a door opening or closing movement SR. After unlocking, the sliding door can be opened.

[0032] If contrastingly a force P2 directed counter to the force P1 acts on the support frame 9, the bar 8 is pressed into the bar catch 10. Accordingly, the lock is not released, so that the sliding door remains in its locked position. Both the force P1 and the force P2 can be produced by pressing on the corresponding door leaf substantially in the direction of the normal of the door leaf plane.

[0033] FIG. 3B shows an alternative embodiment variant of a locking device in comparison to FIG. 3A. The bar 8 shown in FIG. 3B has a recess 20 with a contact surface 40 designed as a flank. The contact surface 40 forms a phase angle b. If the bar 8 connected to the door leaf support frame 9 is moved in the opening direction O of the door, the bar 8 can slide out of the lock.

[0034] A force P1, which triggers the unlocking, acts on the door leaf 6. The control arm 30.1, 30.2 mounted on the support frame 9 forms an acute angle to the support frame 9 when the sliding door is in the closed position or locked position. Accordingly, the force P1 acting substantially in the direction of the normal of the door leaf generates a force FA1 that acts on the support frame 9 in the opening direction O of the sliding door. This means that exclusively the force P1 acting substantially in the direction of the normal of the door leaf plane TE causes both the unlocking and subsequently an opening movement of the sliding door.

[0035] If, in contrast, a force P2 oriented substantially in the direction of the normal of the door leaf plane TE acts on the second door leaf 6′, locking of the sliding door is ensured when an acute angle a formed between the control arm 30.3′, 30.4′ and the door leaf plane TE is greater than the phase angle b. If, however, the phase angle b were greater than the acute angle a, there would be the risk that a force exerted on the second door leaf 6′ could unlock the sliding door, so that a private space behind the closed or locked sliding door would no longer be secured.

[0036] In accordance with the provisions of the patent statutes, the present invention has been described in what is considered to represent its preferred embodiment. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
