Description

The present invention relates to a locking device for a, in particular a plurality of individually movable wings comprehensive, sliding wall or sliding door system, wherein the locking device formed for attachment to a sliding base body, in a closing direction of the body retractable locking element, a transverse to the closing direction acting upon plunger and a deflection device, which brings about an extension movement of the locking element with a movement component in the closing direction upon application of the plunger transversely to the closing direction.

Such locking devices serve to fix a sliding wing of a sliding wall or sliding door system on another wing or on a wall. For example, in many commercial buildings, sliding wall systems composed of a plurality of individually slidable wings, also referred to as "portable walls," are used to selectively cover and release a building opening. To cover the building opening, the individual wings are lined up and locked together. In addition, a locking in the ground is provided for each wing. To release the building opening, the wings are unlocked and pushed overlapping each other in a side parking position or in a recessed in the wall recording.

Since manual locking of each wing is troublesome for an operator, in a locking device according to the preamble of claim 1, the ram to be acted upon transversely to the closing direction ensures that when a moving wing encounters a neighboring wing or a wall, the ram automatically Bar element extends and, for example, comes with a ground socket engaged. The wing is then firmly anchored in the ground. The deflection device can be based on different mechanical principles. For example, a toggle assembly or gear mechanism could be provided to translate horizontal movement of the plunger into vertical movement of the latch member. The disadvantage here is the relatively high production cost. In addition, common solutions take up comparatively much space.

It is an object of the invention to provide a compact and easy to manufacture locking device for sliding wall or sliding door systems.

The object is achieved by a locking device having the features of claim 1.

According to the invention, the locking element and the plunger are combined to form a rigid locking unit which is displaceably guided obliquely to the base body at an angle to the closing direction and thereby forms the deflection device. By moving the locking unit along a slope, a combination of plunger movement and locking element movement can be brought about, which, based on the basic body, includes both a horizontal retraction movement component of the plunger and a vertical extension movement component of the locking element. In this type of force deflection, it is not necessary to provide separate guides for the plunger on the one hand and for the locking element on the other. In addition, can be dispensed with expensive transmission components such as toggle or toothed components. The invention thus enables a particularly easy to manufacture automatic locking device for sliding-wall or sliding door systems. Since in principle only a single movably guided component - namely the rigid locking unit - is present, the system is particularly robust.

Further developments of the invention are specified in the dependent claims, the description and the accompanying drawings.

The locking element and the plunger can be joined to one another or in each case to a common base component of the locking unit, in particular screwed. Alternatively, the locking unit can also be designed as a single component, in particular as a cast component or as a chipping component.

A special embodiment of the invention provides that the locking unit is forcibly guided at an angle of 45 ° to the closing direction on the main body. This allows a direct conversion of a perpendicular to the closing direction, so for example horizontally extending ram movement in a movement of the locking element in the closing direction, for example vertically.

The locking unit can be forcibly guided by means of a sliding guide on the base body. This allows a particularly simple and inexpensive production. However, should it be necessary due to the application specifications, a roller bearing guide could be provided.

According to a special embodiment of the invention, at least one guide groove extending obliquely to the closing direction is formed on the base body, in which a sliding block provided on the locking unit is accommodated. The sliding block may be easily formed by a protruding portion of a side surface of the rigid locking unit. Preferably, the cross-sectional shape of the sliding block corresponds to a rounded rectangle. In order to ensure a particularly reliable guidance, sliding blocks can also be provided on two opposite side surfaces of the locking unit, which are received in corresponding, parallel to each other extending grooves of the body. Depending on the application of the sliding block may be added to the locking unit or formed integrally therewith.

Preferably, the guide groove on a hammer, which opposes a sliding movement of the locking unit in at least one direction a resistance. By such a clamp the locking unit is in the absence a ram loading held in an upper position, so that an undesirable premature extension of the locking element is avoided. The crutch can be formed by a retaining hump in the guide groove, which allows a particularly simple construction.

The locking unit can also be biased by means of a spring device in an unlocked position in which the locking element is in a retracted position. Such a spring device ensures in a reliable manner that the locking unit always assumes the unlocked position in the absence of a tappet loading.

The spring device may comprise an effective between the locking unit and a support surface of the body compression spring or torsion spring. For example, the locking element could be designed bolt-like, wherein a compression spring surrounding the bolt is provided for biasing the locking unit in the unlocked position. Alternatively, a torsion spring could sit in a housing recess behind a guide groove, wherein one leg of the torsion spring is supported on the base body and rests on the other leg of the torsion spring a sliding block received in the guide groove.

According to a further embodiment of the invention, the base body surrounds the locking unit like a housing, in particular wherein at least one extension opening for the locking element and / or the plunger is provided on the base body. Preferably, a common extension opening for the locking element and the plunger is provided, which is sufficiently large to allow a laterally extending to the retraction or extension direction movement of the plunger and the locking element. The design of the base body as a housing allows a compact design and in particular a simple attachment of the base body to a profile element of the wing.

A further embodiment of the invention provides that a locking device for securing to a further wing of Schiebewand- or sliding door system or on a wall formed Beaufschlagungskörper comprising a receptacle for an end of the plunger. When the plunger extends into the receptacle, there is a positive connection between the two associated wings, whereby an undesirable lateral pressing of a wing is prevented.

Preferably, the end of the plunger is displaceable parallel to the closing direction in the receptacle, so that the plunger can move accordingly, when the locking element extends in the closing direction and thereby entrains the plunger.

In particular, the receptacle may define an undercut acting transversely to the closing direction for engagement with a retaining projection provided at the end of the plunger. Such an undercut engagement of the plunger in the receptacle ensures that the plunger is held in a movement of the body from the Beaufschlagungskörper in the recording and moves in this. The locking element is thereby, e.g. up, taken away. In this way, an automatic withdrawal of the locking element from the ground socket at a mounting of the relevant wing, so an automatic unlocking can be effected.

A special embodiment provides that the receptacle is formed as a T-groove extending in the closing direction, which is provided for engagement of a mushroom-shaped end of the plunger, in particular wherein the T-slot has an import extension. Such a configuration allows a particularly simple construction. By import extension, the mushroom-shaped end of the plunger can get into the T-slot, with the undercut engagement following the insertion results due to a transverse movement of the plunger. In principle, the recording could also be designed as a dovetail groove.

The invention also relates to a sliding wall or sliding door system, which in particular comprises a plurality of individually displaceable wings and which has at least one locking device as described above, wherein the main body of the locking device is attached to a sliding wing of the sliding wall or sliding door system.

Fig. 2

shows a locking device for in Fig. 1 illustrated sliding wall system in a release configuration.

Fig. 3

shows the locking device according to Fig. 2 in a closed configuration.

This in Fig. 1 illustrated sliding wall system comprises a plurality of juxtaposed wall panels 11, each comprising a support section 13, a base profile 15 and a between the support section 13 and the base profile 15 extending glazing element 16 include. By means of the support profiles 13, the wall panels 11 are individually slidably suspended in a mounted on a building ceiling 12 running rail 14. Each base profile 15 is associated with a locking device 17, by means of which the respective wall wing 11 in the bottom 20 and at the same time to an adjacent wall wing 11 is fixable. Each locking device 17 comprises a base body 19 fastened to the base profile 15 of a wall panel 11 and a loading body 21 fastened to the base profile 15 of an adjacent wall wing 11. In principle, a loading body 21 could also be attached to a fixed wall.

Fig. 2 shows one of the in Fig. 1 only schematically illustrated locking devices 17 in detail. The main body 19 is designed like a box and houses a rigid locking unit 22, which comprises a downwardly extendable from the base body 19 locking bolt 23 and a to be acted upon in the image to the right plunger 25. Specifically, a deflection device 27 ensures that when the plunger 25 is acted upon in a horizontal direction B by the Beaufschlagungskörper 21 extending the locking bolt 23 from the base body 19 in a vertical closing direction S. The locking bolt 23 can then as in Fig. 3 shown in a bottom sleeve 29 retract to anchor the respective wall wing 11 in the bottom 20.

The locking unit 22 has two sliding blocks 30 which protrude in opposite directions from a central portion 31 of the locking unit 22. The sliding blocks 30 are received in guide grooves 33 of the main body 19, so that the locking unit 22 is forcibly guided in the base body 19. The guide grooves 33 extend in a straight line and extend at an angle of 45 ° to the closing direction S as well as to the loading direction B. The locking unit 22 is thus displaceable exclusively in an angle of 45 ° to the closing direction S in the base body 19. In the upper part of each guide groove 33, a hammer in the form of a retaining tab 41 is provided, which holds the entire locking unit 22 in the upper position via the sliding block 30, provided that the plunger 25 is not acted upon.

The locking unit 22 can be manufactured as a single component, for example in the casting or machining process. Alternatively, the locking bolt 23, the plunger 25 and the sliding blocks 30 may be fixedly attached to the central portion 31, for example by means of screwing.

As shown, the free end 35 of the plunger 25 is mushroom-shaped. Furthermore, a T-groove 37 is formed on a front side of the Beaufschlagungskörpers 21 facing the base body 19, whose longitudinal axis L extends parallel to the closing direction S. At the top of the picture T-groove 37 is located an import extension 39, through which the free end 35 of the plunger 25 can get into the interior of the T-groove 37.

If the in Fig. 1 Farthest right wing 11 is pushed to the left to the adjacent fixed wall wing 11, meets shortly before contact of the two base profiles 15 of the plunger 25 of the locking device 17 of the moving wall wing 11 on the Beaufschlagungskörper 21 of the fixed wall wing 11, wherein the free end of the 35th the plunger 25 passes through the import extension 39 into the T-groove 37. At this time, the latch unit 22 is as in FIG Fig. 2 shown in an upper left open position. The bottom sleeve 29 is arranged such that the locking bolt 23 is exactly above it when the plunger 25 just abuts the rear wall of the T-groove 37.

By the action of the plunger 25 in the direction of application B, the locking unit 22 slides over the retaining projection 41 along the oblique guide grooves 33 in the base body 19 downwards. In this case, on the one hand, the plunger 25 moves vertically downwards in the T-slot 37, the mushroom-shaped end 35 coming into undercut engagement with the T-slot 37. On the other hand, the locking bolt 23 extends in the closing direction S from the base body 19 and enters into a positive engagement with the bottom sleeve 29. In the course of the displacement of the locking unit 22 in the base body 19 of the upper left release position in the Fig. 3 shown lower right closed position sets the moving wall wing 11, the last remaining path to the adjacent fixed wall wing 11 back, so that he finally touched this. The two wall wings 11 then abut each other and are locked together. In addition, the pushed-wall panel 11 is also anchored in the bottom 20.

In order to separate the wall wings 11 from each other again, an operator grasps the rightmost wall wing 11 in the picture and pulls him right away from the other wall wing 11 away. In this case, the retaining projection 43 formed on the mushroom-head-shaped end 35 of the plunger 25 (FIG. Fig. 3 ) on the undercut of the T-groove 37, so that the plunger 25 is held in the T-groove 37. That is, neither the plunger 25 nor the locking bolt 23 can be moved in the horizontal direction. Rather, the locking unit 22 moves exclusively in the vertical direction and slides along the inclined guide grooves 33 in the base body 19 upwards. Here, the end 35 of the plunger 25 moves in the T-groove 37 up to the import extension 39 upwards. At the same time the locking bolt 23 is pulled out of the bottom sleeve 29 in the vertical direction until again in Fig. 2 shown state is reached. The end 35 of the plunger 25 can then be moved out of the T-groove 37 by the import extension 39, so that the two wall wings 11 are separated from each other. The right wall wing 11 can then be pushed away from the adjacent wall wing 11. The right wall wing 11 is thus automatically unlocked by the interaction of plunger 25 and T-groove 37 when mounting.

A locking device 17 according to the invention is particularly simple and inexpensive to produce, since only comparatively few items are required. A particular advantage of the invention is the fact that existing door systems can be easily retrofitted with locking devices 17 according to the invention. Also existing ground sleeves 29 can be used unchanged.
