Abstract

The locking mechanism (2) connected to the running carriage (1) has a main body in two parts (21,22) with tong-shaped clamping elements (27) and in which a locking bolt (23) is movably mounted and which is elastically held in place by an elastic element (24). The locking bolt is moved by the application of force from a first position in which it can fit into a locking element (26) inside, or joined to, the rail (5), into a second position in which it is released from the locking element.

Description

The invention relates to a device for locking guided in rails drives according to the preamble of patent claim 1.

For separating or designing rooms or for closing room or window openings glass or wooden walls, scenes, doors or shops are often used, which are attached to slidable along a rail drives and optionally rotatably mounted.

Normally, these parts, referred to below as separating elements, are displaceable between two end positions at which the drive abuts against a buffer device provided in the rail.

Such a buffer device, which in FIG. 8 shown and in the EP 0 733 766 A2 and the WO 00/55460 has a buffer body 031 which is locked by means of a mounting screw 035 in the rail 5. The buffer body 031 carries an elastic member 037, which serves as an end stop for the body 11 of the drive 1. The buffer body 031 further holds a spring element 036, which forms a snap connection with the drive 1 as soon as it strikes the elastic part 037. The curved spring element 036 is lifted over a central part of an impeller 13 of the drive 1 and clamps this firmly as soon as the drive 1 reaches the elastic part 037.

To move such a detained separating element 90, which in the embodiment of FIG. 8 is connected via a fastening device 91 and a connecting screw 15 to the drive 1, the separator 90 is first released with a small jolt or shock.

The device described is therefore suitable for holding, but not for firmly locking or closing separators.

For secure closure of rooms dividing elements are therefore often provided with bolts or sliders, which are displaced in the Abschliessposition the separating elements, for example, connected to the masonry closure devices.

However, the installation of closure devices on the inner or outer walls of masonry is associated with considerable effort. Due to the relatively soft insulating materials used today, which are applied to the masonry, closures or closing plates, etc. can hardly be anchored to the required stability with the masonry. Reliable protection against unauthorized access can therefore hardly be achieved by means of these termination devices. Closures or closing plates, which are mounted on the masonry, also appear mostly aesthetically disturbing in appearance.

For dividing larger rooms, halls or halls, are also foldable, interconnected by hinges 905 separating elements 902, 903, 904, as in FIG. 9 are shown used. These dividers 902, 903, 904 are locked by being aligned and locked, for example, after closing an associated door 901 by means of a door lock 906. This version with a lockable door is also very expensive and often does not meet the existing needs. The use of closures or closing plates, which are mounted on the masonry, is also possible with the foldable separating elements 902, 903, 904, but with the same disadvantages.

The right divider 904 may also be connected to an adjacent frame 1000 by means of hinges 905. In this case, however, it is no longer movable.

From the BE 466 936 A Further, a device for locking guided in rails drives is known in which the locking device and the associated drive form a unit. The locking device can therefore not be used in combination with existing drives, but only in a very limited area.

The present invention is therefore an object of the invention to provide a device for locking guided in rails drives, which is not afflicted with the described deficiencies.

This object is achieved with a device having the features specified in claim 1. Advantageous embodiments of the invention are specified in further claims.

The device according to the invention, which serves to lock a guided in a rail drive and connected thereto or connectable, has a body in which a locking pin is slidably mounted and held by an elastic element in a first position elastically, so that the locking pin from the first position in which it can engage in a directly or indirectly connected to the rail locking element can be brought by the action of force in a second position in which it is released from engagement with the locking element.

The body of the locking device consists of two parts, which have pliers-shaped clamping elements, by means of which the locking device is firmly connected after connecting the two parts with the drive.

The locking device, which is simple and inexpensive, therefore, allows the safe closure of separating elements, such as sliding doors, sliding shutters or folding walls, which are guided by the drive. The device can be operated in a simple manner manually or electromagnetically. It is particularly advantageous that parts of the closing or locking device, such as closing or locking plates no longer need to be mounted on the masonry, but are integrated in the rail.

The locking element may be part of the already existing rail or preferably a rail-mounted buffer device, which normally stops a separator in the position in which it is also to be closed. The inventive solution therefore combines the locking or closing as well as the buffer function in one embodiment.

By a possible positive connection of locking device and locking a reliably secured closure of separating elements is achieved. This results in a reliable burglary protection, without a lock is needed.

The locking device can also be retrofitted, while avoiding machining, to fitting components or on the body of a drive.

The locking device and the associated locking element are located within the track and therefore are not disturbing in appearance. The part for manual operation of the locking device, a leash, a rope or a chain, is mounted on the locking device and is automatically pushed away when opening and is then not visible from the outside or tangible. Also possible is an electromagnetic actuation of the locking device, which allows the central control of the locking devices.

In a preferred embodiment, it is further provided that the locking device between a first state in which the locking device always automatically closes and a second state in which the locking device does not close, can be switched in a simple manner.

Foldable separating elements 902, 903 and 904, which together with a door 901 serve to close off or to share a room.

FIG. 1 shows a sectioned rail 5, in which a via a connecting screw 15 connected to a separating element drive 1 is guided, with a manual to actuated locking device 2 is connected. The drive 1, which has a drive body 11 and two rolling on running surfaces 51 of the rail 5 and mounted by means of axles 14 wheels 12 and 13, located on the right, formed by a buffer device 3 stop the travel path.

The body of the locking device 2 consists of two by means of connecting means 25 or by means of a screw 252 and a nut 251 interconnected parts 21 and 22, the forceps-shaped clamping elements 27 have (see FIG. 4 ), which firmly clamp the drive body 11 and are therefore rigidly connected thereto. For mutual fixing, the parts 21 and 22 preferably have an anchoring 29 on the sides opposite the clamping elements 27.

The two interconnected parts 21, 22 of the locking device 2 form a chamber 26 which is provided with openings for performing a locking pin 23 261, 263, which have a smaller diameter than the chamber 26 and thus from a first and a second inward directed flange 262, 264 are included.

Within the chamber 26, which is closed on both sides with a respective flange 262, 264, there is arranged a spring element or coil spring 23 which abuts on the one hand the first flange 262 and, on the other hand, presses a collar 231 connected to the locking pin 23 against the second flange 264 and the locking pin 23 thus elastically holds in a first position in which it can engage in a locking element 36. The locking pin 23 displaceably mounted in the openings 261, 263 can therefore be displaced out of the first position into a second position only by external application of force, in which case it is disengaged from the locking element 36.

The chamber 26 and guided therein collar 231 of the locking pin 23 preferably have a rectangular cross-section on, so that the locking pin 23 can not twist and tilt during the axial displacement. By this simple measure, therefore, a trouble-free operation of the device is ensured.

For manual actuation of the locking pin 23 with a leash 4, it is also possible to use a rope or a chain, connected by means of the locking pin 23 can be moved axially. The line 4 is when moving a connected to the drive 1 separating element 90 (see FIG. 8 ) and is therefore not visible from the outside or tangible.

In the in FIG. 1 shown preferred embodiment of the invention, the locking element 36 is connected by means of a fastening screw 34 with the buffer device 3, whereby the locking or closing and the buffer function are combined in one embodiment. The anchored by means of a mounting screw 35 within the rail 5 buffer device 3 has to an elastic member 37, to which the connected to the drive 1 locking device 2 each hits when reaching the end stop.

As in the FIGS. 2 and 3 shown, the locking member 36 aligned against the locking device 36 is plate-shaped or tongue-shaped and mounted such that after the impact of the locking device 2 on the buffer device 3 of the locking pin 23 can penetrate into an opening 363 provided in the locking member 36. The drive 1 with the locking device 2 is therefore stopped by means of the buffer device 3 and then held.

The drive 1 facing part of the locking member 36 is preferably inclined upward so that the locking pin 23 moves under this pushes this up or pushed down by this until it can penetrate into the opening 363.

The buffer device 3, which has a threaded bore 32 for receiving the mounting screw 35 and a threaded bore 33 for receiving the fixing element 36 serving for fastening screw 34 is guided by means of the through a bore 361 in the locking element 36 against the middle piece 52 of the rail 5 guided mounting screw 35 pressed against the running surfaces 51 of the rail 5 and thus locked. By loosening the through a bore 361 in the locking member 36 passed through mounting screw 35 and moving the buffer device 3, the closing position of the separating element can be precisely fixed.

By the positive engagement of the locking pin 23 in the locking member 36, a reliably secured closure of the separating element is achieved. This results in a reliable burglary protection, without a lock is needed. The locking device 2 and the locking element 36 are disposed within the rail 5 and are therefore hardly visible to the user.

A guide system comprising a drive 1 and a buffer device 3 as shown in FIG FIG. 8 are shown can also be subsequently provided in a simple manner with a locking device 2.

FIG. 5 shows a not belonging to the invention drive. The locking device 2 is integrated in the drive 1. A for receiving the locking pin 23 and the coil spring 24 in a chamber 26 serving first part 1121 of the locking device 2 is connected to the body 111 of the drive 1 and is preferably made with this in one piece. The chamber 26 is closed by a second, thinner part 1122, which is connected by a screw 252 to the first part 1121.

FIG. 6 shows the manually operated locking device 2 in a preferred embodiment in which the locking pin 23 can be switched between at least two positions. For this purpose, a mechanism 28 is provided with at least one holding element 281, which serves for hooking connected to the locking pin 23 cam 232. By pulling the locking pin 23, it is suspended in the holding element 281 and released by pulling again. Mechanisms of this type are used, for example, in pens. The locking device 2 can therefore be deactivated in this way, so that the relevant separating element can be moved to the end stop, without being locked. Only when the separator is to be locked, the locking pin 23 is unlocked and moved back into the first position.

In FIG. 6 It is further shown that also the overhead center piece 52 of the rail 5 may be provided with openings 53 into which the locking pin 23 can be inserted. The drive 1 can be fixed in this way not only in the provided with a locking element 36 buffer device 3, but at various points along the path where openings 53 are provided in the rail 5.

The actuation of the locking pin 23, as described above, the easiest way manually. As in FIG. 7 However, an electromagnetic actuation of the locking pin 23 is also possible. For this purpose, for example, a locking pin 23 comprehensive coil 81 is provided, which is supplied from a control unit 80, a current. The control unit 80 is connected to a supply line 82 and via a control line 83, for example with a switch. To optimize the force, the coil 81 is aligned obliquely, so that the locking pin 23 is largely encompassed, but still can retract laterally against the buffer device 3 without bumping. In this way, the

Locking devices 2 are unlocked centrally, which is particularly of great advantage, when the separating elements are moved by means of motors, which are also connected to the central control.

Drives 1 can also be provided on both sides with locking devices 2. Normally separating elements 90 such as sliding doors, sliding shutters or folding walls are guided by the drives 1. However, the invention can also be used advantageously if other objects are connected to drives 1.

Of course, drives and buffer devices can also be realized in various configurations.
