Description

The invention relates to a lock for a Locking device for doors, windows or the like, wherein the locking device has at least one additional lock has and the additional lock via a front tie rod is coupled to the lock and the front tie rod is displaceable via an additional first drive.

DE 202 03 565 U1 describes a locking device for Doors, windows or the like with a main lock and known at least one additional lock, which has a Drawbar are coupled together. The pull rod will via a motorized drive device in both Directions driven, being over the tie rod Bolt bolt of the additional lock can be pushed out and is retractable. With this locking device is over the motor-driven drawbar on the one hand the trap of the main lock, on the other hand the Additional lock operated, that is, the bolt bolt of Additional lock is either pre-locked or zuruckgeschlossen.

The invention has for its object a lock to provide which can be operated with less force and which in a simple way in one Locking device can be integrated with additional locks, the actuation of the latch of the main lock from the Actuation of the additional locks is disconnected.

This task is done with a lock of the type mentioned Art solved according to the invention in that a second Drive via a rear pull rod with the lock is coupled and via the rear tie rod Additional bolt of the additional lock and / or the latch of the Castle can be moved to his or her open position.

In the lock according to the invention two are from each other independent tie rods are provided, one tie rod the lock with one or more additional locks couples and the other tie rod is provided with a drive to retract the latch of the lock. there can the drive as a motor drive or as manual drive. The second drive with the pull rod that the lock with the or Additional locks connects, is driven, can also as a motorized or manual drive be designed. By decoupling the actuation of the Additional locks and the actuation of the latch of the The main lock can make the drives smaller be designed because the required power is lower is. On the other hand, the individual functions can be decoupled be, this means that the additional locks and the latch can take different positions. Therefor there is no longer any need for intermediate positions on the drawbar, but the tie rods can each in their End positions or rest positions remain .. In these The tie rods can either be in suitable positions Holding means or be held by their own weight.

In a further development it is provided that the front Drawbar and the rear drawbar independently of each other are movable, which, as already mentioned, the Decoupling the functions of the additional locks and the Case of the main lock is effected.

There is preferably a lower connecting rod in the lock housing and an upper drive rod is provided, the lower Push rod with the front tie rod and the top one Drive rod are coupled to the rear tie rod. The The main lock has two in its lock housing Connecting rods on, one serving the movement the front tie rod through the lock housing to pass through if two additional locks are provided are, and also by means of a push button within the Lock housing is relocatable, so that an unlocking also by means of a handle or a profile cylinder can take place, whereas the other connecting rod only serves to withdraw the trap.

In a preferred embodiment, the upper one engages Driving rod via an alternating pressure piece at the change and urges him into his open position in her work situation. If the upper drive rod is actuated, that is by it Rest position moved into her work position, then she hooks in one Alternating pressure piece and swings over this Alternating pressure piece the change in such a way that the trap in the Lock housing is retracted.

From this position, the upper connecting rod becomes just below Gravity shifts back to its rest position. The return movement can also be done by a spring, which is housed in the lock housing become.

According to a preferred embodiment, the Profile cylinder both the latch lockable and the Bolt and the latch and, if necessary, the additional bolt zurückschließbar. The operation of the bolt and the latch can therefore regardless of the position of the drive rods respectively.

It is preferred that both are on the rear tie rod lower as well as the upper drive rod from their rest position slidable out. This means that when you press the upper connecting rod also automatically the lower connecting rod is actuated so that not only the trap in the housing of the Main castle is withdrawn, but also the Additional locks can be opened. This requires only the actuation of the rear tie rod.

In one embodiment it is provided that the rear pull rod only in one direction of movement with the lower drive rod is motionally coupled. In the other Direction of movement is the rear tie rod from the lower one Driving rod uncoupled.

In a further development it is provided that both drives only in one direction with the associated pull rod are coupled. This means that when deferred the pull rods do not necessarily also actuate the drives must be provided that these are already their starting positions take in. This will make the Encouraged espagnolette, especially at Lock the system.

The coupling is preferably a thrust coupling. this will achieved in a simple manner that on the Tie rods are riveted to which the drive attacks.

Further advantages, features and details of the invention result from the following description, in which with reference to the drawing a particular preferred embodiment described in detail is. It can be shown in the drawing as well mentioned in the claims and in the description Features individually for themselves or in any Combination be essential to the invention.

A preferred variant provides that the lock over a pusher and / or a profile cylinder (22) is fully openable. The castle therefore has one Panic function on.

According to a preferred embodiment, this is Additional lock designed to be self-locking, this means that the additional lock has both its closed position and also maintains its open position automatically while doing so the associated tie rod in its current position holds.

The one shown in FIG. 1 and with a total of 10 designated embodiment of a locking device has a main lock 12 and two additional locks 14 on. The locks 12 and 14 are on a lock cuff 16 attached. The main lock 12 is with a Lock case cover 18 closed, and there are one Handle nut 20, a profile cylinder 22, a latch 24 and a bolt 26 recognizable. The trap 24 is in the Trap position so that it is from a (not shown) Strike plate, which is located on a door frame, in the main lock 12 can be pushed in. The Additional locks 14 are each with an additional bolt 28 provided, which is pushed out of the additional lock 14 or can be withdrawn into this. The Additional locks 14 are via a front tie rod 30 which is located immediately behind the lock cuff 16 with the main lock 12 coupled. The front tie rod 30 is into an upper front tie rod 30 'which is the upper one Additional lock 14 connects to the main lock 12, and in a lower front tie rod 30 "which divides the lower additional lock 14 connects to the main lock 12.

In Figure 1, two drive devices 32 and 34 recognizable via which the upper front tie rod 30 ' or a rear tie rod 36 are displaceable. Therefor has the drive device 32, as in FIG. 3 recognizable, a slide 38 on one Rivet projection 40 of the upper front tie rod 30 ' attacks. Correspondingly, the drive device 34 is like recognizable from Figure 4, provided with a slide 42, the at the lower free end 44 of the rear tie rod 36 attacks.

FIG. 2 shows that the rear pull rod 36 is suspended in an upper drive rod 46 and the front pull rod 30 in a lower drive rod 48. The lower drive rod 48 extends almost over the entire length of the main lock 12, which can be seen from Figure 6. Accordingly, the upper front tie rod 30 'is suspended from the upper end of the lower drive rod 48.
Correspondingly, according to FIG. 5, the free end of the front tie rod 30 "is hooked into a drive rod 50 of each additional lock 14, via which the additional bolt 28 is closed or pushed out.

In Figure 6, the main lock 12 is in its rest position shown in which the trap 24 the trap position occupies and the bolt 26 is closed. Either the lower drive rod 48 and the upper drive rod 46 are in their resting positions, which means that the additional bolts 28 of the additional locks 14 excluded are.

In FIG. 7, the two drive rods 46 and 48 are in their working positions, into which they have been moved via the drive device 34. The slider 42 was extended from the drive device 34 and has moved the rear tie rod 36 upwards by contacting the lower free end 44. Since the rear tie rod 36 is hooked into the upper drive rod 46, the upper drive rod 46 is likewise moved upwards.
However, the free end of the rear tie rod 36 also engages the free end 52 of the lower drive rod 48 and thus also displaces this lower drive rod 48 upwards.

The displacement of the upper drive rod 46 in the main lock 12 causes a displacement of the alternating pressure piece 54, because a shoulder 56 of the upper drive rod 46 on a nose 58 of the alternating pressure piece 54 attacks and that Alternating pressure piece 54 takes. The alternating pressure piece 54 is in turn articulated on a change 60, which at Relocation of the pressure piece 54 around the follower nut 20 is rotated in a clockwise direction. It takes effect a stop angle 62 of the change 60 on an angle plate 64, which is placed on the lower drive rod 48 is. In addition, an interchangeable extension 66 strikes Trap tail 68 and thereby pulls the trap 24 into the Open position, that is, in the lock housing of the main lock 12. In this position the main lock 12 are both the latch 24 and the bolt 26 withdrawn and the Additional locks 14 opened so that the door or Window can be opened.

FIG. 8 shows the main lock 12 in a position in which the follower 20 does not by actuating one shown pusher is rotated. The turned one Lever nut 20 causes the change 60, the assumes a position as shown in FIG. 7 is. As a result, the trap 24 is also withdrawn and it is, as already mentioned for FIG. 7, via the Stop angle 62 up the lower drive rod 48 postponed. This opens the additional locks 14. Thus, the main lock 12 is open, although the upper one Drive rod 46 has not been operated and still takes its lower rest position.

FIG. 9 shows the main lock 12 in a locked position Position in which the latch 24 comes from the lock case pushed out and the latch 26 is locked.

FIG. 10 also shows the main lock 12 in FIG open position, both the trap 24 and the Bolts 26 are retracted into the lock housing. The Handle nut 20 assumes its rest position (since it is not shown pusher is not pressed). However, on free lower end of the alternating pressure piece 54 of the Profile cylinder and displaces the alternating pressure piece 54 such that the change 60 in the direction of the Is pivoted clockwise and that in FIG. 7 occupies the position shown. This will not only make the Case 24 retracted into the lock case, but it will also the lower drive rod 48 via the stop angle 62 shifted upwards. The upper drive rod 46 takes her Rest position.

FIG. 11 shows the main lock 12 in one position, in which the latch 24 is pushed out of the lock housing is, however, the additional locks 14 their open positions ingest, that is, the additional bars 28 of the Additional locks 14 have been withdrawn. Namely, starting from the position of the main lock 12 according to Figure 7, the drive device 34 back to its rest position driven, then the upper drive rod 46 falls on the ground their own weight down, so that Alternating pressure piece 54 also occupy its rest position can. The switch 60 pivots back to its rest position, so that the latch 24 is pushed out of the lock housing becomes. However, the lower drive rod 48 remains in it shifted position, so that the additional locks 14 after as before occupy their open positions. The door will only still from the extended latch 24 in the closed position held. The lower drive rod 48 is in this position held by that the additional locks 14 both at pushed out additional bolt 28 as well as when retracted Additional bars 28 take stable positions, that is, that the additional locks 14 are self-locking. About the Additional locks 14 are then also the rear ones Pull rod 36 and the lower drive rod 48 in this held in the respective position.
