Description

latch device

technical field

The invention relates to a latching device for a movable wall or door system comprising, in particular, a plurality of individually movable leaves, wherein the latching device comprises: a base body configured to be fixed on said movable leaf; A locking element removable from the base body in the closing direction; a tappet to be loaded transversely to the closing direction; and a deflection mechanism which causes the locking element together with the moving member to move in the closing direction when the tappet is loaded transversely to the closing direction. Move out of motion.

Background technique

Such latching devices are used to secure a movable wall or a movable leaf of a movable door system to another leaf or to a wall. For example in many types of commercial buildings, moving wall systems consisting of a plurality of individually movable leaves (also referred to as "positionable walls") are used to selectively cover and release building openings. To cover architectural openings, the individual leaves are lined up next to each other and interlocked. Additionally, there is a latch on the floor for each leaf. To release the architectural opening, the leaves are unlocked and placed one above the other in a lateral position or moved into receptacles embedded in the wall.

Since the manual latching of each individual leaf is cumbersome for the operator, in the latching device according to the preamble of claim 1 the tappet to be loaded transversely to the closing direction is used when the moving leaf hits an adjacent When the sash or the wall is mounted, the locking element is automatically extended and engages, for example, with the floor bushing. The fan is then fixedly anchored in the ground.

In this case, the steering mechanism can be based on different mechanical principles. For example, an articulated lever arrangement or a toothing mechanism can be provided in order to convert the horizontal movement of the tappet into a vertical movement of the locking element. A disadvantage here is the relatively high production costs. Furthermore, conventional solutions require relatively large construction space.

Contents of the invention

The object of the present invention is to provide a compact and easily producible latching device for a sliding wall or sliding door system.

This object is achieved by a latching device having the features of claim 1 .

According to the invention, the locking element and the tappet are combined to form a rigid locking unit which is positively guided on the base body so as to be displaceable obliquely to the closing direction and thus forms the steering mechanism. A movement of the locking unit along the ramp can result in a combination of a movement of the plunger and a movement of the locking element, which includes both a horizontal movement component of the plunger and a vertical movement component of the locking element relative to the base body. With this type of force deflection it is not necessary to provide separate guidance for the tappet on the one hand and the locking element on the other hand. In addition, complex transmission components such as articulating levers or toothed components can be dispensed with. The invention thus makes it possible to realize an automatic latching device for moving wall or moving door systems which can be produced particularly simply. Since in principle there is only one single movable-guiding component, namely the rigid locking unit, the system is particularly robust.

Further developments of the invention are given in the subclaims, the description and the drawing.

The locking element and the tappet can be engaged with each other or separately, in particular screwed, to a common basic component of the locking unit. Alternatively, the locking unit can also be formed as a single component, in particular as a cast or cut part.

A special embodiment of the invention provides that the locking unit is positively guided on the base body so as to be displaceable at an angle of 45° to the closing direction. This enables a direct conversion of a movement of the tappet extending at right angles to the closing direction, ie, eg horizontally, into a movement of the locking element in the closing direction, eg vertically.

The locking unit can be positively guided on the base body by means of sliding guides. This enables particularly simple and cost-effective production. However, roller bearing guides can also be provided if required based on application specifications.

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 guide groove the slide provided on the locking unit is accommodated. The slide can be formed in a simple manner by lateral projecting sections of the rigid locking unit. Preferably, the cross-sectional shape of the slider corresponds to a rounded rectangle. In order to ensure particularly secure guidance, slides can also be provided on two opposite sides of the locking unit, said slides being accommodated in corresponding guide grooves running parallel to one another in the base body. Depending on the application, the slide can be joined to the locking unit or formed in one piece with the locking unit.

Preferably, the guide groove has a stop which counteracts the displacement movement of the locking unit with resistance in at least one direction. Such a stop secures the locking unit in the upper position when the tappet is not loaded, so that an undesired premature removal of the locking element is avoided. The stop can be formed by a retaining projection in the guide groove, which enables a particularly simple construction.

The locking unit can also be biased by means of a spring mechanism into an unlocked position in which the locking element is in the retracted position. Such a spring mechanism ensures that the locking unit always assumes the unlocked position when the tappet is not loaded.

The spring mechanism can comprise a compression spring or a torsion spring acting between the locking unit and the support surface of the base body. The locking element can, for example, be designed in the form of a pin, wherein a compression spring surrounding the pin is provided for pretensioning the locking unit into the unlocked position. Alternatively, the torsion spring can be located in the housing gap behind the guide groove, wherein one leg of the torsion spring is supported on the base body and the slide received in the guide groove bears against the other leg of the torsion spring.

According to a further embodiment of the invention, the base body surrounds the locking unit in a housing-like manner, in particular wherein at least one removal opening for the locking element and/or the tappet is provided on the base body. Preferably, a common extension opening for locking element and plunger is provided, which is large enough to enable a lateral extension of the plunger and locking element with respect to the direction of insertion or extension. The embodiment of the basic body as housing enables a compact construction and in particular simple mounting of the basic body on the profiled part of the fan.

A further embodiment of the invention provides that the latching device comprises a carrier body designed for fastening to the moving wall or another leaf of the moving door system, which carrier body has a receptacle for the end of the tappet. If the tappet protrudes into the receptacle, there is a form-locking connection between the two associated leaves, whereby an undesired lateral pressing of the leaves is prevented.

Preferably, the end of the tappet is displaceable in the receptacle parallel to the closing direction, so that if the locking element moves out in the closing direction and entrains the tappet there, the tappet can be moved accordingly.

In particular, the receptacle can define an undercut acting transversely to the closing direction for engaging with a retaining projection provided on the end of the tappet. Such an undercut of the plunger engages in the receptacle for the purpose of holding the plunger in the receptacle and moving it when the base body and the loading body are moved apart. The locking element is here for example driven upwards. In this way it can be brought about that the locking element is automatically pulled out of the floor sleeve, ie automatically unlocked, when the respective leaf is opened.

A special embodiment provides that the receptacle is formed as a T-slot extending in the closing direction, which T-slot is provided for engaging the mushroom-head-shaped end of the tappet, in particular wherein the T-slot has an insertion extension . Such a construction enables a particularly simple construction. By introducing the extension, the mushroom head-shaped end of the tappet can enter the T-groove, wherein an undercut engagement occurs due to the transverse movement of the tappet subsequent to the introduction process. In principle, the receptacle can also be designed as a dovetail groove.

The invention also relates to a mobile wall or door system comprising in particular a plurality of individually movable leaves and having at least one latching device as described above, wherein the basic body of the latching device Fixed to a movable wall or movable leaf of a movable door system.

Description of drawings

The invention is described below by way of example with reference to the accompanying drawings.

Figure 1 shows a moving wall system with a plurality of individually movable wall fans according to the present invention;

Figure 2 shows the latching arrangement for the moving wall system shown in Figure 1 in the released setting;

FIG. 3 shows the latching device according to FIG. 2 in the closed setting.

Detailed ways

The mobile wall system shown in FIG. 1 comprises a plurality of wall fans 11 arranged close to each other in a row, said fans respectively comprising a support profile 13, a base profile 15 and a glass extending between the support profile 13 and the base profile 15. Element 16. The wall fans 11 are individually movably suspended by means of support profiles 13 in slide rails 14 fixed to the building ceiling 12 . Assigned to each plinth profile 15 is a latching device 17 , by means of which the corresponding wall leaf 11 can be fastened in the floor 20 and at the same time the adjacent wall leaf 11 can be fastened. Each latching device 17 comprises a base body 19 fixed to the base profile 15 of a wall leaf 11 and a loading body 21 fixed to the base profile 15 of an adjacent wall leaf 11 . In principle, it is also possible to mount the loading body 21 on a fixed wall.

FIG. 2 shows the latching device 17 shown only schematically in FIG. 1 in detail. The base body 19 is designed as a housing and accommodates a rigid locking unit 22 comprising a locking bolt 23 which can be moved downwards from the base body 19 and a tappet 25 which is to be loaded to the right in the drawing. In particular, the deflection mechanism 27 is used to move the locking bolt 23 out of the base body 19 in the vertical closing direction S via the loading body 21 when the tappet 25 is loaded in the horizontal loading direction B. The locking bolt 23 is then inserted into the floor sleeve 29 as shown in FIG. 3 in order to anchor the associated wall leaf 11 in the floor 20 .

The locking unit 22 has two slides 30 which project in opposite directions from a central section 31 of the locking unit 22 . The slide 30 is accommodated in a guide groove 33 of the base body 19 , so that the locking unit 22 is positively guided in the base body 19 . The guide groove 33 runs straight and at an angle of 45° to the closing direction S and also at an angle of 45° to the loading direction B. As shown in FIG. The locking unit 22 can thus only be moved in the base body 19 at an angle of 45° to the closing direction S. FIG. In the upper region of each guide groove 33 there is a stop in the form of a holding projection 41 which holds the entire locking unit 22 via the slider 30 as long as the tappet 25 is not acted on. in the above position.

The locking unit 22 can be produced as a single component, for example, by casting or cutting. Alternatively, the locking bolt 23 , the tappet 25 and the slide 30 can also be fixedly joined to the middle section 31 , for example by means of a screw connection.

As shown, the free end 35 of the tappet 25 is designed in the shape of a mushroom head. Furthermore, a T-shaped slot 37 is formed on the front side of the loading body 21 facing the base body 19 , the longitudinal axis L of which extends parallel to the closing direction S. FIG. Located at the upper end of the T-shaped slot 37 in the figure is an insertion extension 39 through which the free end 35 of the tappet 25 can reach into the interior of the T-shaped slot 37 .

If the wall leaf 11 located on the far right in FIG. 25 hits the loading body 21 of the fixed wall leaf 11 , wherein the free end 35 of the tappet 25 enters the T-shaped slot 37 through the introduction extension 39 . At this moment, the locking unit 22 is in the upper left open position, as shown in FIG. 2 . The ground sleeve 29 is arranged in such a way that if the tappet 25 hits exactly on the rear wall of the T-shaped slot 37 , the locking bolt 23 lies exactly above it.

By loading the tappet 25 in the loading direction B, the locking unit 22 slides downward in the base body 19 along the inclined guide groove 33 over the holding projection 41 . On the one hand, the tappet 25 is moved vertically downward in the T-shaped groove 37 , wherein the mushroom-head-shaped end 35 engages the T-shaped groove 37 in an undercut engagement. On the other hand, the locking bolt 23 is moved out of the base body 19 in the closing direction S and enters a form-locking engagement with the floor sleeve 29 . During the movement of the locking unit 22 in the base body 19 from the upper left release position to the lower right closed position shown in FIG. fan 11 so that the moving wall fan eventually touches the adjacent stationary wall fan. The two wall fans 11 then collide with each other and latch each other. In addition, the pushed-pull wall fan 11 is also fixed in the floor 20 .

In order to separate the wall fans 11 from each other again, the operator grabs the wall fan 11 which is located furthest to the right in the figure and pulls it away from the other wall fan 11 to the right. The retaining projection 43 ( FIG. 3 ) formed on the mushroom-head-shaped end 35 of the tappet 25 rests on the undercut of the T-shaped groove 37 so that the tappet 25 is fixed in the T-shaped groove 37 . That is to say, neither the tappet 25 nor the locking bolt 23 can move in the horizontal direction. Instead, the locking unit 22 is moved only in the vertical direction and slides upward in the base body 19 along the inclined guide groove 33 . In this case, the end 35 of the tappet 25 is moved upwards in the T-groove 37 until it is introduced into the widening 39 . At the same time, the locking bolt 23 is pulled out of the ground sleeve 29 in the vertical direction until the state shown in FIG. 2 is reached again. The end 35 of the tappet 25 can then be moved out of the T-slot 37 via the introduction extension 39 so that the two wall leaves 11 are separated from each other. The right wall leaf 11 can then be moved away from the adjacent wall leaf 11 . The right wall leaf 11 is then automatically unlocked when pulled apart by the interaction of the tappet 25 and the T-shaped slot 37 .

The latching device 17 according to the invention can be produced particularly simply and cost-effectively, since only relatively few parts are required. A particular advantage of the invention can be considered to be that an existing door installation can easily be retrofitted with a latching device 17 according to the invention. Furthermore, the existing ground sleeve 29 can be used unchanged.
