Description

The invention relates to a locking device with the features of the preamble of claim 1.

From the DE-U-202 03 565 a closure device according to the preamble of claim 1 for doors, windows or the like with a main lock and at least one additional lock is known, which are coupled together via a tie rod. The pull rod is driven via an additional motor drive device in both directions, wherein a bolt bolt of the additional lock is pushed out and retractable via the pull rod. In this locking device on the one hand, the case of the main lock is operated on the motor-driven pull rod, on the other hand, the auxiliary locks are operated, that is, the bolt of the auxiliary lock is either preconnected or closed.

The EP-A-0 798 436 shows a locking device that can be operated only by either the pusher or with the lock cylinder. The locking device has a main lock and an additional lock with an additional bolt, which can be prefaced via a front drive rod and retracted via a rear drive rod in the additional lock box.

The invention has for its object to provide a locking device which can be actuated with less force, the operation of the case of the main lock can be decoupled from the operation of additional locks.

This object is achieved with a lock of the type mentioned in the present invention, that a second drive is coupled via a rear tie rod to the main lock and the rear tie rod, the case of the lock in its open position is displaced and that the front tie rod and the rear tie rod are independently displaceable.

In the lock according to the invention two mutually independent tie rods are provided, wherein the one drawbar coupling the main lock with one or more auxiliary locks and the other pull rod is provided to retract the case of the lock with a drive. In this case, the drive can be designed as a motor drive or as a manual drive. The other drive, with which the pull rod, which connects the main lock with the additional locks or, is driven, can also be configured as a motor or as a manual drive. By decoupling the operation of additional locks and the operation of the case of Main lock can on the one hand the drives are made smaller, since the required power is lower. On the other hand, the individual functions can be decoupled, this means that the additional locks and the trap can take different positions. This requires no more intermediate positions in the pull rod, but the tie rods can each remain in their end positions or rest positions. In these rest positions, the tie rods can be held either by suitable holding means or by their own weight.

The front tie rod and the rear tie rod are independently displaceable, which, as already mentioned, the Decoupling of the functions of the additional locks and the case of the main lock is effected.

With preference, a lower drive rod and an upper drive rod are provided in the lock housing of the main lock, wherein the lower drive rod with the front tie rod and the upper drive rod are coupled to the rear tie rod. Thus, the main lock has in its lock housing on two drive rods, the one serves to pass the movement of the front pull rod through the lock housing, if two additional locks are provided, and which is also displaced by a pusher within the lock housing, so that unlocking also can be done by means of a pusher or a profile cylinder, whereas the other drive rod only serves to retract the trap.

In a preferred embodiment, the upper drive rod is vulnerable to change over an alternating pressure piece and urges in its working position this in its open position. If the upper drive rod is actuated, that is, moved from its rest position to its working position, then it hooks into an alternating pressure piece and pivots about this alternating pressure piece the change such that the case is drawn into the lock housing.

From this position, the upper drive rod is moved back under gravity alone back to its rest position. The return displacement can also be supported by a spring, which is housed in the lock housing.

According to a preferred embodiment, both the bolt vorschließbar over the profile cylinder and the latch and the latch and optionally the additional latch are zurückschließbar. The operation of the bolt and the latch can therefore be independent of the position of the drive rods.

With preference, both the lower and the upper drive rod are displaceable out of their rest position via the rear pull rod. This means that when operating the upper drive rod and the lower drive rod is automatically actuated, so that not only the case is withdrawn into the housing of the main lock, but also the additional locks are opened. This requires only the operation of the rear tie rod.

In one embodiment, it is provided that the rear pull rod is only motion-coupled to the lower drive rod in one direction of movement. In the other direction of movement, the rear drawbar is from the lower Drive rod uncoupled.

In a further development it is provided that both drives are coupled only in one direction with the respective associated tie rod. This means that when resetting the tie rods, the drives do not necessarily have to be operated with, as long as they already take their initial positions. As a result, the ease of the espagnolette lock is promoted, especially when locking the system.

With preference, the coupling is a sliding coupling. This is achieved in a simple manner in that stops are riveted on the tie rods, which acts on the drive.

Further advantages, features and details of the invention will become apparent from the following description in which, with reference to the drawing, a particularly preferred embodiment is described in detail.

A preferred variant provides that the lock over a pusher and / or a profile cylinder (22) is completely openable. The lock thus has a panic function.

According to a preferred embodiment, the additional lock is self-holding, this means that the additional lock automatically retains both its closed position and its open position while holding the associated pull rod in its current position.

That in the FIG. 1 shown and a total of 10 designated embodiment of a locking device has a main lock 12 and two auxiliary locks 14. The locks 12 and 14 are attached to a lock cuff 16. The main lock 12 is closed with a lock box cover 18, and there are a follower 20, a profile cylinder 22, a latch 24 and a latch 26 recognizable. The latch 24 is in the trap position, so that it can be pressed by a (not shown) strike plate, which is located on a door frame in the main lock 12. The additional locks 14 are each provided with an additional latch 28 which can be pushed out of the additional lock 14 or withdrawn into it. The additional locks 14 are coupled via a front pull rod 30, which is located immediately behind the lock cuff 16, with the main lock 12. The front drawbar 30 is divided into an upper front drawbar 30 'connecting the upper auxiliary lock 14 to the main lock 12 and a lower front drawbar 30 "connecting the lower auxiliary lock 14 to the main lock 12.

In FIG. 1 are also two drive means 32 and 34 can be seen, via which the upper front pull rod 30 'and a rear pull rod 36 are displaced. For this purpose, the drive device 32, as shown in FIG. 3 recognizable, a slider 38 which on a Rivet projection 40 of the upper front pull rod 30 'attacks. Accordingly, the drive device 34, as shown FIG. 4 recognizable, provided with a slider 42 which engages the lower free end 44 of the rear drawbar 36.

The FIG. 2 shows that the rear tie rod 36 are 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 the entire length of the main lock 12, resulting in FIG. 6 is apparent. At the upper end of the lower drive rod 48, therefore, the upper front pull rod 30 'is mounted.
Accordingly, according to FIG. 5 , the free end of the front drawbar 30 "mounted in each case a drive rod 50 of each additional lock 14, via which the auxiliary bolt 28 is closed or pushed back.

In the FIG. 6 is the main lock 12 shown in its rest position, in which the latch 24 assumes the case position and the latch 26 is closed back. Both the lower drive rod 48 and the upper drive rod 46 are in their rest positions, which means that the additional bolt 28 of the additional locks 14 are excluded.

In the FIG. 7 are the two drive rods 46 and 48 in their working positions, in which they have been moved over the drive means 34. In this case, the slider 42 has been extended from the drive device 34 and has displaced by attachment to the lower free end 44, the rear tie rod 36 upwards. Since the rear tie rod 36 is suspended in the upper drive rod 46, the upper drive rod 46 is equally shifted 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 displaces this lower drive rod 48 also upwards.

The displacement of the upper drive rod 46 in the main lock 12 causes a shift of the alternating pressure piece 54, as a shoulder 56 of the upper drive rod 46 engages a nose 58 of the alternating pressure piece 54 and takes the alternating pressure piece 54. The alternating pressure piece 54 is in turn articulated to a change 60, which is rotated by the pusher 20 in the clockwise direction when the alternating pressure piece 54 is displaced. In this case, a stop angle 62 of the change 60 engages an angle plate 64, which is placed on the lower drive rod 48. In addition, a change-over extension 66 abuts on the latch tail 68 and thereby pulls the latch 24 into the open position, that is to say into the lock housing of the main lock 12. In this position of the main lock 12, both the latch 24 and the latch 26 are retracted and the auxiliary locks 14 are opened so that the door or window can be opened.

The FIG. 8 shows the main lock 12 in a position in which the pusher 20 is rotated by operation of a pusher, not shown. The rotated follower 20 causes a rotation of the change 60, which assumes a position as shown in the FIG. 7 is shown. As a result, the case 24 is also withdrawn and it is, as already to FIG. 7 mentioned above the stop angle 62, the lower drive rod 48 is moved upwards. As a result, the additional locks 14 are opened. Thus, the main lock 12 is open, although the upper drive rod 46 has not been operated and still assumes its lower rest position.

The FIG. 9 shows the main lock 12 in the locked position in which the latch 24 is pushed out of the lock case and the latch 26 is pre-closed.

The FIG. 10 shows the main lock 12 also in the open position, with both the latch 24 and the latch 26 are retracted into the lock housing. The pusher 20 assumes its rest position (since not shown pusher is not actuated). However engages at the free lower end of the alternating pressure piece 54 of the profile cylinder and displaces the alternating pressure piece 54 upwards such that the change 60 is pivoted in the clockwise direction and in the FIG. 7 shown position occupies. As a result, not only the case 24 is withdrawn in lock housing, but it is also displaced over the stop angle 62, the lower drive rod 48 upwards. The upper drive rod 46 assumes its rest position.

The FIG. 11 shows the main lock 12 in a position in which the case 24 is pushed out of the lock housing, but the auxiliary locks 14 occupy their open positions, that is, the additional bolt 28 of the auxiliary locks 14 are withdrawn. Namely, starting from the position of the main lock 12 according to FIG. 7 , the drive means 34 again moved to its rest position, then falls the upper drive rod 46 due to its own weight down, so that the alternating pressure piece 54 can also assume its rest position. The change 60 pivots back to its rest position, so that the latch 24 is pushed out of the lock housing. However, the lower drive rod 48 remains in its displaced position, so that the additional locks 14 still occupy their open positions. The door will only still held by the ejected latch 24 in the closed position. The lower drive rod 48 is held in this position characterized in that the additional locks 14 occupy stable positions both when ejected additional bolt 28 and retracted additional latch 28, that is, that the additional locks 14 are self-holding. On the additional locks 14 but then the rear tie rod 36 and held over this lower drive rod 48 in the respective position.
