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 displaceably guided on the main body at an angle of 45 ° to the closing direction. 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 particular embodiment of the invention, at least one obliquely extending to the closing direction guide groove is formed on the base body, in which a at the Latch unit provided sliding block is added. 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, said sliding blocks being received in corresponding, mutually parallel, guide grooves of the base 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 held in the absence of a ram loading 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 comprises a loading body formed for attachment to another wing of the sliding wall or sliding door system or on a wall, which has a receptacle for one 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.

The invention will now be described by way of example with reference to the drawings.

1 shows an inventive sliding wall system with several individually movable wall wings.

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

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

This in 1 illustrated sliding wall system comprises several juxtaposed wall panels 11 , which each have a support profile 13 , a base profile 15 and a between the support profile 13 and the base profile 15 extending glazing element 16 include. By means of the supporting profiles 13 are the wall wings 11 individually movable in one on a building ceiling 12 fixed track rail 14 suspended. Each base profile 15 is a locking device 17 assigned, by means of which the respective wall wing 11 in the ground 20 and at the same time to an adjacent wall wing 11 can be fixed. Each locking device 17 includes one on the base profile 15 a wall wing 11 attached basic body 19 and one on the base profile 15 a neighboring wall wing 11 attached admission body 21 , In principle, could also on a fixed wall a Beaufschlagungskörper 21 to be appropriate.

2 shows one of the in 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 one down from the main body 19 extendable latch bolt 23 and a to be acted upon in the image to the right plunger 25 includes. Specially ensures a deflection 27 for having an impact on the pestle 25 in a horizontal direction B by the Beaufschlagungskörper 21 an extension of the locking bolt 23 from the main body 19 takes place in a vertical closing direction S. The locking bolt 23 can then as in 3 represented in a ground socket 29 retract to the respective wall wing 11 in the ground 20 to anchor.

The locking unit 22 has two sliding blocks 30 on, in opposite directions from a central section 31 the locking unit 22 protrude. The sliding blocks 30 are in guide grooves 33 of the basic body 19 picked up so that the latch unit 22 in the main body 19 is forced. The guide grooves 33 are straight 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 exclusively at an angle of 45 ° to the closing direction S in the body 19 displaceable. In the upper area of each guide groove 33 is a hamper in the form of a retaining hump 41 provided, which over the sliding block 30 the entire locking unit 22 holds in the upper position, provided the plunger 25 is not charged.

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 pestle 25 as well as the sliding blocks 30 firmly to the central section 31 be attached, for example by means of fittings.

As shown, the free end 35 of the plunger 25 designed mushroom-shaped. Furthermore, at one of the main body 19 facing front of the Beaufschlagungskörpers 21 a T-slot 37 formed, whose longitudinal axis L extends parallel to the closing direction S. At the picture in the upper end of the T-slot 37 there is an import extension 39 through which the free end 35 of the plunger 25 into the interior of the T-slot 37 can get.

If the in 1 furthest right wall wing 11 to the left to the adjacent fixed wall wing 11 is pushed, meets shortly before a contact of the two base profiles 15 the pestle 25 the locking device 17 of the moving wall wing 11 on the admission body 21 of the fixed wall wing 11 , where the free end 35 of the plunger 25 about the import extension 39 into the T-slot 37 arrives. At this time, the locking unit is located 22 as in 2 shown in an upper left open position. The ground socket 29 is arranged such that the locking bolt 23 located exactly above her when the plunger 25 straight on the back wall of the T-slot 37 abuts.

By applying the plunger 25 in the loading direction B slides the locking unit 22 overcoming the retaining hump 41 along the oblique guide grooves 33 in the main body 19 downward. On the one hand moves the plunger 25 in the T-slot 37 vertically downwards, with the mushroom-shaped end 35 in an undercut engagement with the T-slot 37 arrives. On the other hand, the locking bolt moves 23 in the closing direction S from the main body 19 from and enters into a positive engagement with the ground socket 29 , In the course of the displacement of the locking unit 22 in the main body 19 from the upper left release position to the in 3 shown lower right closed position sets the moving wall wing 11 the last remaining part of the way to the neighboring fixed wall wing 11 back, so that he finally touches it. The two wall wings 11 then they bump into each other and are locked together. In addition, the pushed-up wall wing 11 also in the ground 20 anchored.

To the wall wings 11 again separate an operator takes the rightmost in the picture wall wing 11 and pull him to the right of the other wall wing 11 path. It is based on the mushroom-shaped end 35 of the plunger 25 trained retaining projection 43 ( 3 ) at the undercut of the T-slot 37 off, leaving the pestle 25 in the T-slot 37 is held. That means neither the ram 25 still the locking bolt 23 can be moved in a horizontal direction. Rather, the locking unit moves 22 exclusively in the vertical direction and thereby slides along the oblique guide grooves 33 in the main body 19 up. This is where the end moves 35 of the plunger 25 in the T-slot 37 until the import extension 39 up. At the same time the locking bolt 23 in the vertical direction from the ground socket 29 pulled out until again the in 2 shown state is reached. The end 35 of the plunger 25 can then through the import extension 39 from the T-slot 37 be moved out so that the two wall wings 11 are separated from each other. The right wall wing 11 can then from the adjacent wall wing 11 be pushed away. The right wall wing 11 So it is through the interaction of plunger 25 and T-slot 37 unlocked automatically when mounting.

A locking device according to the invention 17 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 easily with locking devices according to the invention 17 can be retrofitted. Also existing ground sleeves 29 can be used unchanged.
