Description

Field of the invention

The invention relates to a locking device according to the preamble of claim 1 and a room closure with such according to the preamble of claim 13.

State of the art

The closing of doors and gates is often accomplished by lock and bolt systems. Heavy doors and gates in particular tend not to engage properly in the door or door frame, or to deviate from their original fit with continuous use. The consequence of such inaccuracies in the fit between door and frame are also that doors and gates with a lock and bolt system can no longer be closed; The bolt is no longer movable in the lock, as the lock and bolt are shifted from each other. A simple constructive measure to compensate for this fit inaccuracy is to widen the latch receptacle of the castle and therefore to increase the game of the bolt in the castle. A disadvantage of this simple adaptation measure is that an electrical closure monitoring is difficult to realize.

In the GB 05169 a bolt is slidably mounted on a plate. The plate is for example fixed to a door leaf. When closed, the bolt is received in a socket. The socket is fixed by means of a retaining plate, for example on a door frame. The bush is slidably received on the retaining plate transversely to the displacement direction of the bolt. To adjust and fix the socket in a position in which the socket and the bolt are aligned, an adjustment screw is provided. The screw is also disposed on the support plate and displaces the sleeve in its rotation in the clockwise or counterclockwise direction relative to the holding plate. Although the sliding sleeve is very simple and compensates distance deviations between the bolt and the socket, the adjusting screw provides however, an exposed part that is easily damaged. Also, an electrical lock monitoring, which could be provided on the socket, can be realized only with great effort.

The US 5,352,001 also discloses a slidable bolt that snaps into a bolt receiver. The Bolzenaufnehmer includes a slot and a sleeve which is provided in the slot. The sleeve is displaceable by means of an adjusting screw along the slot. Thereby, a position of the sleeve is adjustable by turning the adjusting screw in the slot in which the bolt is aligned with the sleeve. The Bolzenaufnehmer is complex in its construction and additionally has the disadvantages already outlined above.

The DE 27 36 029 shows a device for locking and unlocking two mutually displaceable elements. The device comprises a longitudinally displaceable full-clutch member, which is received in the locked state of mutually displaceable elements in a coupling hollow member. The coupling hollow member is received transversely to the locking direction movable in a bearing block. The bearing block is firmly connected to one of the two displaceable elements. The coupling hollow body can be blocked in relation to the bearing block. This is done for example by hydraulic cylinders or coil springs, which press the coupling hollow member to the bearing block. The device is for special applications with very high loads, such as prevail, for example, on ships, designed and therefore consuming. Also, an electrical lock monitoring, which could be provided on the coupling hollow organ, to accomplish only with great effort.

Object of the invention

Object of the present invention is therefore to provide a lock and bolt system that does not have the above-mentioned disadvantage. A further object is to show ways and means that allow the proposed lock and bolt system on all commercially available frames and doors or construction profiles tamper-proof mountable. Yet another task is to show a lock and bolt system that is very easy to equip with a lock monitoring.

description

According to the invention, the object is achieved by a locking device according to the preamble of claim 1 by the features of the characterizing part.

The locking device has in a known manner a latch part and a lock part for arrangement on an opening having a space closure and a door closing the opening. The latch member has in a likewise known manner a bolt holder and a relative to the bolt holder in a direction displaceable bolt. The lock part is known to have a receiving opening for receiving a first end of the bolt. In this locking device according to the invention is a transverse guide device which has the latch member in addition to the longitudinal guide means, and spring means which are in operative connection with the longitudinal guide means and the transverse guide means and cushion a displacement of the bolt in a Querjustierrichtung available. The adjustment direction is advantageously directed transversely to the displacement direction of the bolt and parallel to the door plane. The Querjustierrichtung is defined by the transverse guide device. The spring means hold the latch member or the latch in a central home position with respect to the Querjustierrichtung. This makes it particularly easy to transfer the latch part in an aligned position relative to the lock part. This is of particular advantage when the locking device is mounted so that the weight of the latch or the lock member is held by the spring means. A further advantage of the locking unit according to the invention is that the longitudinal guide device and the transverse guide device are provided on the latch part. The lock part is fixed. Electrical or electronic closing monitoring can therefore be provided without any effort to the lock part. Passing inaccuracies between the receiving opening and the latch, which occur during assembly or by delaying the door during use of the locking device, can be compensated by the transverse guide device. This is of particular advantage if, for reasons of application technology, the clearance between the bolt and the receiving opening of the lock part has to be made particularly small.

In a preferred embodiment, the transverse guide device is guided on the longitudinal guide device. This allows easy access to the spring means. The locking unit according to this embodiment is to be assembled quickly. Furthermore, the Federmittelvorspannung is very easy to adjust by the open design.

In a particularly preferred embodiment, the longitudinal guide device is guided in the transverse guide device. This design requires a small number of items and is therefore inexpensive to produce.

Advantageously, the guide device consists of at least one slider and a guide rail which cooperates with the slider. This simple and at the same time cost-effective guide device has the advantage that the bolt, designed as a sliding body of the guide rail, or the whole latch part, provided with a slider or a guide rail, and / or the receiving opening formed as a sliding body of the guide rail or the entire lock part, with provided a slider or a guide rail, reliable and secure against jamming are performed. It can also be the bolt part or the lock part designed as a sliding body of the guide rail.

Another advantage of this guide device is that the locking device can be designed so that the guide rail either on the bolt part and / or on the lock part, or fixedly mounted. The at least one sliding body can be mounted either fixedly on the door or on the room closure or on the lock part or on the latch part. This variety of design variants allows various mounting options on virtually all on the market doors, gates and room closures.

According to a preferred embodiment, means are provided for fixing the lock and / or latch part with respect to the adjustment direction. This embodiment has the advantage that a once selected adjustment of the bolt or lock part can be maintained. An adjustment during each locking process can be omitted, although another necessary adjustment is always feasible.

Advantageously, the clearance between the receiving opening and the bolt is a maximum of 2 mm, is preferably 1 mm and most preferably 0.8 mm. By implementing these small gap dimensions, the inventive locking device is particularly suitable for monitoring applications. Only the small gap dimensions allow an electrical or electronic switching part necessary for monitoring applications to be arranged on the lock or bolt part.

Advantageously, the first end of the bolt and the receiving opening each have a chamfer on their side oriented toward the bolt. The chamfers are in operative connection with one another in such a way that the bolt is introduced into the receiving opening during a closing process.

In one embodiment, an electrical or electronic switching part of an electrical or electronic alarm device is arranged on the lock part or the latch part. This has the advantage that a reliable remote monitoring of the closed state of the locking device is feasible.

According to a further embodiment, the at least one sliding body is received in a groove of a construction profile. The big advantage of this embodiment is that the locking device can be integrated into construction profiles. This is important if the use of such profiles for design reasons is inevitable, or if the locking device is subsequently arranged on construction profiles.

The subject of the present invention is also a room closure having an opening with a door closing the opening and a locking device according to the invention, wherein the guide rail is arranged on the door. The use of the locking device has the advantage that the closing state of doors can be monitored inexpensively and also a subsequent installation of the locking device is particularly easy to implement.

The FIGS. 1 to 3 show a locking device 11 with a latch part 13 and a lock part 15th FIG. 1 indicates that the latch member 13 is fixed to a door 17 and the lock member 15 at a space termination 19. The locking member consists of a slidable in the direction of longitudinal displacement 21 bolt 23. A longitudinal guide means 25 serves the bolt 23 as a guide and support in its movement along the longitudinal displacement direction 21. On the latch 23, a handle 27 is arranged. The lock member 15 has a receiving opening 29. For easier accommodation of the bolt 23 in the receptacle 29 is located at the end of the bolt 27 which faces the receiving device 29, a chamfer 31. The receiving opening 29 is also rounded by a chamfer 33. Again FIG. 3 can be seen, the latch member 13 has a transverse guide device 34. The transverse guide device 34 comprises two sliding body 35 and a guide rail 37. On the side facing away from the handle 27 of the longitudinal guide means 25, the two sliding bodies 35 are arranged. The latch member 13 is forcibly guided by the slider 35 in the guide rail 37 along a Querjustierrichtung 47. At the two sliding bodies 35, a respective spiral spring 39 is attached with its first end. The two coil springs 39 extend in the guide rail 37 and are fixed with their ends facing away from the closing part 13 with clamping bolt 41 on the guide rail 37. By the coil springs, the closing part 13 is held centrally to the longitudinal extent of the guide rail 37 in a basic position. It would also be conceivable that the guide rail 37 is arranged on the longitudinal guide device 25 and the sliding body 35 are fixedly mounted on the door 17 (not shown in the figures).

The FIGS. 4 to 6 show an embodiment in which the lock part is movably received in the guide rail. The guide device shown is identical to the guide device of the embodiment of the FIGS. 1 to 3 with the difference that the two sliding bodies 35 are arranged on the lock part 15. Another embodiment arises from the fact that the guide rail 37 is arranged on the longitudinal guide device 25 and the sliding bodies 35 are fixedly mounted on the space closure 19 (not shown in the figures).

FIG. 7 shows an embodiment in which the guide rail 37 is replaced by the groove 43 of a commercial construction profile 45. As already explained above, it is also conceivable that the sliding bodies 35 are arranged on the lock part 15 are. The sliding body 35 are then also in the groove 43 of a construction profile 45 can be accommodated.

The FIGS. 8 to 11 show an embodiment of the locking unit 11 in which the latch 23 at the same time in the longitudinal displacement direction 21 and in the Querjustierrichtung 47 in the longitudinal guide device 25 is displaceable. The longitudinal guide device 25 takes over the task of the sliding body 35 in this embodiment. The guide rail 37 is then no longer present in this embodiment of the locking device, since the longitudinal guide unit is guided in the transverse guide unit 34. This design is compact and requires fewer parts and can be implemented very cheaply.

In order to make the locking device 11 tamper-proof, it is advantageous to cover required fastening material after assembly, to render it insoluble or to use special tamper-resistant fastening material.

The inventive locking device 11 works according to the in the FIGS. 1 to 3 illustrated embodiment as follows: The door 17 is closed by means of the handle 27. The bolt 23 is moved along the longitudinal sliding direction 21 in the direction of the lock part 15 and strikes the lock part 15. Subsequently, the latch member 13 is moved in the direction of Querjustierrichtung 47 until the latch 23 is aligned with the receiving opening 29. The latch 23 is then inserted into the receiving opening 29 until it touches the lock member 15 with the handle 27. Achieving the alignment between latch 23 and receiving opening 29 is facilitated by the interaction of the chamfers 31 and 33.

In a further embodiment, the aligned position between latch 23 and receiving opening 29 can be fixed after a single adjustment, for example by a clamping device. If necessary, the selected determination of the latch member 13 to the lock part 15 at any time be canceled and re-adjustable.

The adjustable locking device 11 is particularly advantageous if the clearance between the latch 23 and the receiving opening 29 2 mm and less. Changes in the position of the door 17 relative to the frames come in particular with continued use but also by insufficient adjustment conditions. In the stated application of a small margin between latch 23 and receiving opening 29 lead door displacements of 1 mm already for clamping the latch 23 in the receiving device 29. Slit of maximum 2 mm between the latch 23 and the receiving opening 29 find their application in particular when the locking device 11 is electronically or electrically monitored. The electrical or electronic switching parts used in such alarm monitoring must be arranged on the latch 23 or on the receiving opening 29. Even small deviations in the fit tolerance between latch 23 and receiving opening 29 inevitably lead to a malfunction of mentioned switching parts. An exact interaction of locking part 13 and lock part 15 is therefore important for a reliable function of the alarm monitoring.
