Abstract

The lock has a connecting rod movable by a pusher bolt, and a locking unit (25) for releasing of movement of the rod and movable from a locking position. A slider (19) is locked with a latch knob by a front surface (24) in an opening position. The locking connection is detachable between the slider and the latch knob in a closing position. The slider is movable relative to the knob by an electrical signal transmitter.

Description

The invention relates to a lock according to the preamble of claim 1.

Such a castle is from the EP 0796 967 B1 already known. In this lock a pusher from a substantially horizontal middle position in two directions is displaced. In a first position, in which the pusher is moved down, a latch of the lock is withdrawn and the door can be opened.

If the pusher is moved upwards from the middle position, then an espagnolette slide movable in the lock housing is brought into a blocking position. For this purpose engages in the housing parallel to the latch verschiebarer latch by means of a locking member in a recess of the espagnolette gate valve. This prevents the espagnolette slide from moving any further. At the espagnolette slide a drive rod is coupled for movement, which is thereby also fixed in a blocking position.

In order to be able to bring about an opening state of the lock and the door from this closed position, a lock cylinder of the lock must be actuated. This engages with a driver on a locking member which defines a slider relative to the bolt. The slider is displaceably mounted in the housing and on the bolt and is displaced by the driver with decoupled locking member. In this case, the slide abuts a blocking member which has caused the locking position of the trigger by fixing a follower in the locking position of the drive rod. The locking position of the drive rod can then be released via the pusher, which is moved from the center position down.

By this construction of the lock a locking position is possible, which can be lifted only on the key and the pusher but can be effected without the key.

The object of the invention is to achieve even easier operation of the castle or the door equipped with a simpler structure.

The solution of this problem is achieved in a lock according to the preamble of claim 1, characterized in that the slide is slidable via an electrical signal transmitter relative to the bolt tail. As a result, apart from unlocking via the lock cylinder, unlocking via the signal transmitter is also available, which can respond to, for example, electronic and / or contactless opening means. The lock can also be part of a locking system in which several locks are remotely controlled.

It is preferably provided that the signal transmitter drives a solenoid which acts directly or indirectly on the slide. By the direct control by means of a solenoid, a large motive force can be released with a small space requirement. In an indirect interaction, however, the amount of movement can be maximized, so an increased travel can be achieved.

It is further provided that the locking member is attached to the slider, so that the already proven operation can be maintained via the key.

It has also been found that the locking member should preferably be stored on the bolt tail. Although it can be provided that the locking member is attached to the bolt or the bolt tail. However, this complicates and weakens the design of the latch.

It is further contemplated that the signal transmitter is mounted in the lock main housing. The operation can then be performed by a key with electronic trigger or non-contact e.g. via a transponder.

But it may also be advantageous to accommodate the signal generator in a housing adjacent to the lock housing, since more space is available here.

In order to facilitate the engagement of the driver of the lock cylinder is provided that the locking member is displaceable transversely to the slide displacement movement.

Alternatively to the solution according to claim 1, according to claim 8 can be locked in a lock with up and displaceable drive rod by actuation of a follower rod and a coupled to the espagnolette latch Riegelvor- and in which the Treibstangenverlagerbarkeit is locked in a corresponding locking position the closed position by means of a locking device, and wherein the locking device for releasing the espagnolette from the locking position is rückverlagerbar, provided that in the blocking position, the rotational movement of the nut at least in the opening direction blocking blocking member is provided, which is releasable via an electrical signal generator.

This embodiment allows a simplification of the structure of the castle. While in the first embodiment, the unlocking of the nut is effected by a slider movable on the bolt tail, which is displaced by the operation of the lock cylinder or by the signal generator relative thereto and thereby brings the blocking member in a non-locking position, here a signal generator acts indirectly on the Blocking member, so that the bolt is designed simplified and the slide can be omitted.

Here, the blocking member with a locking extension in the blocking position engage under a locking level of the nut, so that the locking of the nut takes place directly.

It can also be provided in addition, that the blocking member can be brought via the signal generator in its blocking position, so that both the release position and the locking position can be controlled.

The lock in a first embodiment according to Fig. 1 has a transversely for Stulperstreckung forward and rückschließbaren latch 1 and a retractable by pressing the pusher 4 case 2. For bar exclusion or for Fallenrückzug a nut 3 is provided, which is held by a fork-shaped slide 5 in a sprung center position. The slider 5 is acted upon by a spring 6, which is supported in the lock housing.

The slider 5 has fork-shaped, the Drückereinstecköffnung on a collar embracing forks 7, which rest on diametrically opposed cam 8 of the nut 3. From the in the Fig. 1 shown position, the nut can be on the pusher 4 in one of the two possible directions - namely in the clockwise direction downwards or upwards - pivoted. In this case, the slide 5 is displaced by acting on the respective cam 8 on the fork tine 7 under compression of the spring 6. The nut 3 has a recess 11 into which a transmission nose 10 of a transmission lever 9 protrudes. As a result, the transmission lever 9 is pivotally displaced during a displacement of the nut 3. The recess 11, in which the transmission nose 10 protrudes, is circumferentially larger than the width extension of the transmission nose 10. As a result, the displaced transmission lever 9 remains in its up or down pivoted displacement position, even if the nut 3 springs back according to the Schieberbeaufschlagung in the middle position.

The transmission lever 9 acts on a drive pin 12, which sits on a drive rod connection slide 13. The espagnolette slide 13 is connected at its end to a drive rod 14, so that the drive rod 14 is displaced in a pivoting movement of the transmission lever 9 in a clockwise direction upwards. In a reverse pivotal movement of the transmission lever 9, the drive rod is displaced accordingly downwards.

The case 2 is retracted over the nut 3 in a conventional manner when the pusher 4 from the in the Fig. 1 shown position down - in a clockwise direction - is pivoted. In addition to the case 2, the bolt 1 is also movable over the nut 3. For this purpose, the bolt 1 with a bolt tail 18 ( Fig. 2 ), which has a slanted slot 15 on its rear side. The oblique slit 15 consists of a longer straight central portion and end adjoining extensions 16, 17 which are substantially parallel to the Espagnolette exclusion run. In this inclined slot 15 engages a driving pin 13 "of the espagnolette 13 a.

In a movement of the espagnolette 13, the bolt 1 is thus closed or closed back, wherein the driving pin 13 "occurs in the extension 16 in the vorgeschlossenen latch position and in the extension 17 in the locked latched position.

In order to lock the drive rod 14 in the pre-closed latch position, a recess 27 is provided in the rear side 13 'of the drive rod connection slide 13. In the fully forward displaced latch position is a locking member 25, 25 'in a rearward against spring force position. The driving pin 13 "is in this position in the transition region between the inclined slot 15 and extension 16. In another espagnolette displacement, during which the driving pin 13" completely enters the extension 16, the locking member 25 enters the recess 27. For this purpose, on the EP 0 796 967 B1 to which reference is made in full.

In the in Fig. 1 In the illustrated position, the drive rod connection slide 13 is in a lowered position and the driving pin 13 "is located in the extension 17. The latch 1 is closed back by pressing a pusher 4 in the counterclockwise direction, the nut 3 is pivoted and via the transmission lever 9 of the espagnolette 13 in The driving pin connecting slide 13 associated entrainment pin 13 "passes through the inclined slot 15 along with a bar lock.

In the in Fig. 2 shown functional position of the latch 1 reaches its fully excluded position. The drive pin 13 "assigned to the catch 1" enters the extension 16. The drive rod connection slide 13 is displaced linearly until the blocking member 25 enters the catch recess 27. This ensures that a spring 26 exciting the lock member 25 essentially only during the When the locking member 25 enters the latching recess 27, the spring 26 then relaxes. When the bolt 1 is closed, a blocking member 36 is carried along by a catching edge 40 '. the slider 19 abuts a lug 36 "of the blocking member 36 and carries it parallel to the latch 1. The blocking member 36 reaches the pivoting region of the nut 3 with a section 36 'which has a limited axial recess in this region, so that a radial locking edge on the nut 3. At this blocking edge abuts the blocking member 36, so that the nut 3 is prevented from pivoting in a clockwise direction EP 0 796 967 B1 directed.

Starting from the in Fig. 2 illustrated blocking position can be displaced by actuation of a locking cylinder, not shown in the drawings of the slide 19 in a back-closed position. For this one acts in the Fig. 2 indicated catch of the lock cylinder has an end face 24 of a slide 19 arranged transversely to the slide displacement direction and by a spring 21 kraftbeaufschlagten locking member 20. The locking member 20 has evidently the Fig. 2 , in which the slider 19 is shown in its rear view, on its rear side a latching lug 22, which cooperates with a counter-latching 23 of the here indicated bolt tail 18. By transverse displacement of the locking member 20, this latching of the latching lug 22, and the counter-latch 23 is dug and by rotation of the lock cylinder in a clockwise direction ( Fig. 2 ), the slider 19 is rearranged by the fact that the driver of the lock cylinder abuts the released after the pushing back of the locking member 20 inner edge 19 'and carries the slider 19. In this case, the locking member 25 is disengaged from the recess 27, so that the drive rod 14 is released again. When pushing back the slide 19 this abuts with the stop 40 "to the blocking lever 36 and its nose 36" whereby the blocking member 36 is urged into a nut 3 releasing position.

By releasing the nut 3, a closing of the bolt 1 and the drive rod 14 can now be achieved via the pusher 4.

In addition, it is provided that the slide 14 is displaceable by triggering an electrical signal transmitter relative to the bolt tail 18. This is evidently the Fig. 4 and 5 Control electronics are provided on a secondary housing 50 adjacent to the lock main housing, which control electronics are suitable for controlling a drive 51 on the slide 19. The drive 51 may consist of a solenoid 52, in which a fixed to the slider 19 coil to a displaceable Anchor 53 which is fixed to the bolt 1 and the bolt tail 18. In this case, the solenoid 52 is such that it is fixed in each case in the end positions and is brought into the other position only when renewed excitement.

The drive 51 is arranged so that it also carries out the necessary transverse displacement of the locking member 20. For this purpose, the armature 53 along the locking member 20 is preferably arranged along the latching 23. On the movable armature 53, a retraction slope 54 pointing in the direction of the latching element 20 is provided ( Fig. 3 ), with which the locking member 20 can be withdrawn and out of engagement with the Rieglschwanz 18 device. For this purpose, the armature 54 must be at least limited mobility to the latch 1. But it can also be provided a second, independently of the solenoid 52 to be controlled lifting magnet, which retracts the locking member against the force of the spring 21.

In addition, in addition to a solenoid 52, of course, a motor can be provided which displaces the slider 19 relative to the latch 1. In order to release the engagement of the locking member 20 while a solenoid can be provided, which includes the locking member 20 as a movable armature.

It can also be provided deviating from the aforementioned embodiment, that the solenoid 52 or the engine only indirectly attach to the slider 18. This can be done for example by an intermediate arm, which is supported on the housing and a lever arm allows a larger travel.

In addition to the above-described embodiment may alternatively be provided, however, that the signal generator acts directly on a drive, which blocks the espagnolette slide 13 and - if necessary acts on the blocking member 36 with a second drive. It can be provided that in the blocking position, the rotational movement of the nut 3 at least in the opening direction blocking blocking member 36 via the electrical signal generator releasably but also possibly in its blocking position can be brought.

Finally, it should be pointed out that the drive rod is used to control other locking points, which are housed in other secondary lock housings.
