The front closable catch with a locking cam (25) is blocked in a reverse path of connecting rod from their locked position. The blocking section of the catch downward window trains a stage, before which the locking cam of the completely unlocked catch lies.

Description

The invention relates to an espagnolette with a lockable from a back-closed position in a vorgeschlossene position latch, and with a transversely movable from a release position into a locking position drive rod, wherein the prefix of the bolt in the release position of the drive rod according to a profile engagement of a reduced in width Blocking portion of a latch passage window of the drive rod is blocked in a broad side recess of the bolt, and the pre-locked latch with a locking cam blocks a return displacement of the drive rod from its locked position.

An espagnolette of the aforementioned kind is from the DE 29501645 U1 previously known. There, the drive rod has a latch passage window. This latch passage window has a blocking portion which is formed by two V-shaped converging portions of the window wall. In the release position of the drive rod, these sections of the window are in broad side recesses of the bolt, so that the bolt is positively locked against a transverse displacement to the drive rod. This positive connection between the drive rod and bolt is canceled by a downward displacement of the drive rod. After that can be brought by means of closing operation of a profile cylinder of the bolt in a pre-closed position. In the pre-closed position of the bolt, a locking cam on the bolt has entered a rear recess of a driving rod connecting slide and thus blocks its rearward displacement. In a return displacement attempt, a push-pull cam of the espagnolette slide comes against the detent cam. The drive rod is there motion-locked in the locked on both sides lock position.

The invention has the object of providing a Treibstangeschloss with the above-described functionality manufacturing technology simple form.

The object is achieved by the invention specified in the claims, each claim represents an independent solution to the problem.

The claim 1 provides initially and essentially before that the blocking portion of the bolt passage window is formed by a step. Prior to this stage is the locking cam of the fully locked bolt. The blocking section is formed by two sections of a window wall as in the prior art. These are preferably formed by two opposing projections. The latter can have a rectangular contour, so that two end faces of the projections run parallel to one another. Two further marginal edges of the rectangular contour can be aligned with each other and extend transversely to the extension direction of the drive rod. In this way, the step is formed in a simple manner, in front of which the locking cam of the fully locked bolt is located. In this position, a locked on both sides lock position is also locked motion. Only when the bolt is closed back from its vorgeschlossenen position, the drive rod can be moved to the release position. This is possible even after a slight displacement of the bolt from its pre-closed position, since the locking cam only comes in the final phase of the Vorschlussbewegung before the blocking portion of the bolt window. However, the drive rod can only be moved to the release position when the latch is completely closed. Then, namely, the two projections can enter into corresponding, near the free end of the bolt head arranged broad side recesses of the bolt head. The latch passage window has another portion which lies beyond the two opposing protrusions. The projections thus form a Sidecut of a window. This further window portion forms the passage opening for a trap, which is retractable by pressing a pusher. With this pusher and the drive rod between release position and locking position can be swung back and forth. This is done on the one hand by a rotation of the drive nut by a lock cylinder in a clockwise direction and on the other hand by a rotation of the drive nut in the counterclockwise direction. The drive nut has an arm with which it acts on the drive rod or on a drive rod connection slide. The drive nut has a second arm, which is held by a spring assembly in a neutral center position. The bolt tail has a greater width than the bolt head. In this respect, the bolt forms a step. The locking cam is part of this level. He has a broadside increase and thus lies in the direction of displacement of the drive rod in its release position in front of the bolt head. This has the consequence that the drive rod with fully vorgeschlossenem bolt as good as can not move. If the latch is slightly withdrawn from the fully-closed position, the locking cam moves out of the movement path of the blocking section of the latch passage window, so that the drive rod can be displaced slightly in the direction of its release position. Their release position can reach the drive rod but only when the latch is fully retracted, otherwise the blocking would occur in front of the bolt head. A further displacement of the drive rod would then be blocked. Only at fully zurückgeschlossenem bolt aligned broadside recesses with the two opposite, the blocking portion forming projections. These can then enter the broadside recesses. Along with this form-fitting engagement but then the Vorschließbarkeit the bolt is blocked.

The castle has a castle floor and a castle ceiling. Both are spaced apart and consist of stamped and bent parts. Between Schlossboden and Schlossdecke there is the Schlosseingerichte. This lock has a latch 4. This has a latch tail with an end projection on which an actuating arm 1 attacks. The trap extends through a portion 23 'of a window 23 of a drive rod 9, the back of a cuff 27 is guided. The cuff 27 has a the plan view of the case head 4 'adapted window in which the case head 4' is guided. At the case head 4 'engages the rear of the arm of a leg spring 3. The other arm of the leg spring 3, which forms a latch spring, is supported on a pin fixed to the housing. At this pin 28 and the actuating arm 1 is supported.

The actuating arm 1 is mounted on a nut 2. This nut 2 has a square opening for the passage of a pusher mandrel. From the nut 2 protrude in a diametrical opposite transfer cams 18. These driving cams 18 are each in driving recesses 19 which are associated with the actuating arm 1. The width of the Mitnahmeaussparungen 19 is greater than the width of the driving cam 18. This allows the nut 2 rotate by a certain angle, without the operating arm is drehmit towed. Join the driving cams 18 but against the wall of the driving recess 19 and the nut 2 further example. Clockwise rotated so pivots the rotational movement of the nut 2, the actuating arm 1, which engages the rear projection of the latch tail. Along with this pivotal movement of the actuating arm 1, the case 4 is withdrawn.

The nut 2 is a control arm 5 is formed. This control arm 5 has the shape of a tooth of a gear. The sides pointing away flanks of the Control arm 5 are involute curved and are at attack edges 10,11. The two attack flanks 10,11 are spaced from each other by the width of the control arm 5 and face each other.

The attack flanks 10, 11 are formed by projections 12,13. Each projection 12, 13 belongs to a slide 7, 8 of a spring assembly. The slides can be made of plastic or metal. They are preferably molded molded parts.

Like that FIGS. 10 and 11 can be seen, the slides 7, 8 each form a pot-like recess 16. The two pot-like recesses 16 of the two slides 7, 8 face each other and each store one end of a compression spring 6, with which the two slides 7, 8 are acted upon away from each other. Again FIG. 6 can be seen, the two slides 7, 8 are compressed by a U-shaped bracket 17. The U-legs of the retaining clip 17 forms a contact surface for the side walls of the slide 7, 8. The headband 17 is not shown with positive locking means connected to the lock housing. To this end protrude from the narrow sides of the U-leg of the retaining clip 17 or from the two U-webs of the retaining clip 17 projections, which dive into corresponding recesses of the castle floor and / or the castle ceiling, so that in this way the headband 17 is fixed fixed in the castle. The U-web of the retaining clip 17 extends parallel to the direction of displacement of the case. 4

In the in the FIG. 6 shown mounting position of the two slides 7, 8, the compression spring 6 is tensioned. Each slide 7, 8 forms a web 14, which is the extension of a side wall of the cup-like depression 16. Each of the two webs 14, 15 has a direction transverse to the displacement direction of the slider or to the direction of extension of the compression spring 6 protruding projection 12, 13. The projections 12, 13 form the two attack flanks 10,11.

Again FIG. 11 can be seen, each of the two slides 7, 8 guide extensions 30. These protrude in the mounted state in guide slots either the lock floor or the lock cover, so that the two slides 7, 8 are linearly guided. The two webs 14,15 partially run side by side. The protruding from the webs projections 12,13 extend partially over the web 14, 15 of the other slide 7, 8, so that the two flanks 10,11 in the direction of movement of the slide 7, 8 are opposite.

The nut 2 engages with a further driving arm which also rests with motion clearance in driving recesses, on a espagnolette 20. This espagnolette arm 20 acts on a drive rod slide 29, which is positively coupled to the drive rod 9. By rotational movement of the nut 2 thus not only the case 4 can be withdrawn, but also the drive rod 9 between the release position and the locking position are reciprocated back and forth.

The drive rod 9 is of a coupling extension of the espagnolette 29, which engages in a coupling window of the drive rod 9, moved. The drive rod 9 has an elongated window 23 through which the substantially rectangular plan 21 having a bar occurs. The two opposite broad sides of the bolt head 21 'form recesses 24. These broad side recesses 24 are grooves which are slightly removed from the end face of the bolt head 21'. The bolt head 21 'forms a step 26. This stage, which is located in the transition region to the bolt tail, has on its lower side a broadside projection which forms a locking cam 25. The latch can be actuated by a lock cylinder, via the drive nut 31. For this purpose, levers not shown are provided.

In the FIG. 2 the drive rod 9 is shown in the locked position. The window 23 of the drive rod 9 has a sidecut, which are formed by two opposing blocking projections 22. These rectangular blocking projections form with a rectangular narrow side in each case a step 22 ', which extends transversely to the extension direction of the drive rod 9. The two mutually aligned steps 22 'thus extend transversely to the displacement direction of the drive rod. The two blocking protrusions 22 have end flanks 22 "which are spaced apart from one another by less than the width of the bolt head 21 ', but the distance between the two end flanks 22" is greater than the distance between the two bottoms of the broad side recesses 24, so that the blocking protrusions 22 by upward movement of the drive rod 9 from the in FIG. 2 shown locking position can dive into the broad side recesses 24, as shown in the FIG. 5 is shown, in which the drive rod is displaced into a release position.

Beyond the sidecut formed by the blocking projections 22, the window 23 continues in a fall passage window 23 ', in which the head 4' of the trap 4 rests.

While the drive rod 9 can be displaced by operating the nut 2, the latch 21 is actuated by the drive nut 31, for example, by a lock cylinder. He can be extended by turning the drive nut 31 so far until the step 26 abuts the drive rod 9 and the cuff 27.

In the FIG. 3 , in which the bolt 21 is completely vorgeschlossen, is the step 26 and thus also the locking cam 25 in front of the cuff 27 within the window 23 of the drive rod 9. In the FIG. 2 It can be seen that the locking cam 25 is in the movement path of one of the two blocking projections 22. The drive rod 9 can thus in the in FIG. 3 illustrated bolt position not be shifted into the open position. If the latch 21 is slightly withdrawn, the locking cam 25 comes out of the movement path of the blocking projection 22 and allows a displacement of the drive rod 9. The drive rod 9 can not be completely relocated to the release position, since the stage 22 'is no longer against the Arretierungsnocken 25, but against the lower side surface of the bolt head 21 'abuts. The drive rod can only be moved to the release position when the bolt in the in the Figures 1 and 2 shown position is completely closed, so that the blocking projections 22 can enter the broad side recesses 24 of the locking head 4 '.

The operation of the castle is the following:

Is starting from the in the Figures 1 and 2 shown operating position, the nut 2 is rotated clockwise, the espagnolette arm 20 is dragged clockwise. This has the consequence that the espagnolette 29 is moved upwards. He tows the drive rod 9 in the release position.

Along with the rotation of the nut 2 in the clockwise direction, the driving cam 18 against the edges of the driving recess 19 and drag the actuating arm 1 so that the case head 4 'is retracted. During the rotation of the nut 2, the control arm 5 is supported on the attack flank 11 of the projection 13 of the slider 7 from. The slider 7 is displaced to the right with simultaneous tension of the compression spring 6. This generates a restoring force on the nut 2. During the linear displacement of the projection 13, the curved flank of the control arm 5 slides on the planar attack flank 10 from. The end position with retracted Trap 4 shows the FIG. 7 ,

If, starting from this operating position, the nut 2 is no longer subjected to torque, the compression spring 6 can relax. The displaced slider acts on the control arm 5 and pivots the nut 2 into the in FIG. 8 shown position. Due to the rotational release of the Treibstangebetätigungsarmes 20 relative to the nut 2 this remains in the upwardly displaced position, as it FIG. 8 represents. However, the nut 2 is held by the two slides 7, 8 in the neutral center position, in which the control arm 5 both attack edges 10, 11 abut.

In this, also in the FIGS. 4 and 5 shown operating position, the latch 21 can not be moved.

If, starting from this operating position, the nut 2 is rotated in the opposite direction, the attack flank 11 of the projection 13 of the other slide 7 is acted upon. Due to the clearance of the driving cam 18 in the driving recess 19 of the actuating arm 1 is not dragged. However, the espagnolette arm 20 is taken, which the espagnolette 29 from the in FIG. 8 shown release position in the in FIG. 9 entrains shown locking position. If the nut 2 is relieved, so the force of the compression spring 6 provides for a provision of the nut 2 in the neutral center position. Because of the rotational release of the espagnolette arm 20 but remains in its downwardly displaced position.

In the course of the downward displacement of the drive rod, the actuating projections 22 have exited from the broad side recesses 24. The blocking projections 22 have also been shifted downwards so far that they have exited from the trajectory of the locking cam 25. The latch 21 can now be prefixed until the step 26 steps on the cuff 27. Now the locking cam 25 is in the path of movement of the locking projection 22, so that the drive rod 9 is motion-locked.

Was starting from the in FIG. 8 or in the FIGS. 4 and 5 shown operating position, the drive rod is not completely shifted to the locked position, the blocking projection 22 is in the movement path of the locking cam 25. This has the consequence that the locking head 21 'may indeed be displaced. However, the latch 21 can not be completely closed. This can be felt, for example, by a lock cylinder during the rotational displacement of the drive nut 31. The user can thus determine by locking operation or actuation of the device for a lock cylinder 31, whether the drive rod 9 is fully extended to the locking position, since only then the bolt 21 can be completely preconnected.

Since the espagnolette is locked with fully locked latch 21, the latter can only be moved to a release position when the latch 21 has been closed back.
