EP3336286B1 - Lock, preferably panic lock, and lock assembly with a lock and a strike box - Google Patents

Description

The invention relates to a lock, preferably a panic lock, in particular provided for interacting with a mating box, with a arranged in a lock housing latch, with a spring-loaded, at least one tumbler projection to cooperate with the lock housing having tumbler and cooperating with the tumbler release slide. Furthermore, the present invention relates to a lock assembly with a lock of the aforementioned type and a lock ejector having a counter box, for use in two-leaf doors.

A lock of the type mentioned is from the DE 20 2012 012 294 U1 known. This lock has a lock cover and a lock case with a retractable by means of a panic bolt and a lock the locking bolt in its extended locking position locking device. The guard locking device is guided between the lock cover and the lock case.

From the DE 10 2004 013 646 A1 a panic lock comes out. The lock has a latch and a latch, wherein the proposed latch is retracted by applying a latch spring projecting from the end face of the latch, which releases the tumbler with a control tab of a trigger tail, by a latch return lever engaged by a latch return spring.

The EP 3 336 286 A1 relates to a lock with a bolt arranged in a lock housing, with a spring-loaded tumbler and cooperating with the tumbler release slide.

From the DE 10 2009 003 860 A1 a lock with a particular of a closing member of a lock cylinder in a bolt displacement direction back and forth lockable latch, which is held in the pre-closed position of a tumbler, out.

In addition, the reveals EP 0 902 141 A1 a panic lock with a housing, a tumbler arranged therein for a bolt and executed in the latch in the closing direction release lug, wherein the release lug in excluded and is locked in the locked latch by at least one projection arranged on the tumbler.

In another known lock is on a door a lock with a latch, while at the other door a counter box is provided with a Latch ejector. The lock is usually a panic lock, so a lock with panic function, which may otherwise have a profile cylinder to close. To realize the panic function, a release slide is provided on the lock, which cooperates with the tumbler of the lock and releases the tumbler when actuated. After release of the tumbler the spring-loaded latch in the lock housing is moved from the excluded to the enclosed position. After the lock enclosure, the door can then be opened easily.

In particular, in cases where the lock has a profile cylinder for closing, it may happen in certain positions of the profile cylinder provided on PZ-finger, that the PZ-finger rests on the tumbler, without triggering them. This is usually a specific inclination of the profile cylinder with respect to the tumbler. In such a position, it may happen despite actuated release slide, that the bolt is not moved from its excluded position in the enclosed position, as it comes to a blocking or tilting of the tumbler on the PZ-finger and the bolt is not triggered.

In order to solve the above problem, it is known from the prior art, to apply the tumbler with a relatively strong spring, wherein the spring force of this acting on the tumbler spring is so high that it the PZ-finger of the profile cylinder from any inclination can push away and the aforementioned tilting is prevented. The relatively high spring force thus prevents a malfunction of the lock and ensures that the panic function is realized in any case.

The disadvantage, however, is that when using a spring acting on the tumbler with high spring force in a two-leaf door, the force acting upon actuation of the Riegelauswerfers must be relatively high in order to overcome the spring force acting on the tumbler.

Object of the present invention is therefore to provide a lock of the type mentioned, in which the panic function can be ensured safely and easily.

The aforementioned object is achieved according to the invention in a lock of the type mentioned above essentially in that the tumbler a first tumbler part spring-loaded with a first spring on which the at least one tumbler projection is provided, and a second spring-loaded second and the first tumbler part has separate tumbler part and that the release slide acts only on the first tumbler part and that the first tumbler part and the second tumbler part are spring-loaded transversely to the direction of movement of the trigger slide and movable.

In the solution according to the invention, the tumbler formed integrally in the prior art is divided into at least two separate tumbler parts. Both tumbler parts are each subjected to a separate spring, wherein preferably the spring force of the first tumbler acting on the first spring less to significantly less, namely at least by a factor of 2, in particular by two to ten times lower than the spring force of the second spring , Moreover, it is so that the release slide only on the first tumbler part, which is preferably less strong spring force acts. As a result, the bolt ejector provided on the counter box only has to be subjected to a comparatively small force in order to actuate the release slide via the bolt ejector. On the other hand, the force acting on the second tumbler spring force is preferably greater to much larger than the spring force of the first spring and can readily be chosen so high that the PZ-finger of the profile cylinder is not tilted and blocking the panic function is prevented. However, the spring force of the second spring does not affect the function of the trigger slide or the triggering of the panic function on the latch ejector of the counter box, since each of the tumblers is ultimately loaded by its own spring and can be operated independently.

As a result, the essential advantage of the present invention is that the force required to move or lift the first tumbler part over the trigger slide is less than when lifting or pushing over the second tumbler part. For this it is crucial that the tumbler projection is provided on the first tumbler part, which can be actuated both via the bolt ejector and via the profile cylinder, whereas the second tumbler part has no blocking effect and is decoupled from the actuation via the trigger slide. By dividing the only used in the prior art Spring in two individual springs is thus on the one hand only a smaller force to trigger the panic function on the mating box required, on the other hand, a proper functioning of the panic function is ensured as a tilting between the PZ-finger and the tumbler due to the high spring force of the second spring can not occur.

In the lock according to the invention, moreover, the release slide in the bolt or bolt body in the direction of movement of the bolt, that is, in and against the Ausschließ- or Einschließbewegung of the bolt, guided longitudinally movable. On the one hand, the direction of movement of the trigger slide is defined, which is ultimately movable transversely to the longitudinal axis of the lock or lock housing, on the other hand is made clear by the longitudinally movable guide and arrangement in the locking body that the release slide moves together with the bolt when the bolt - or excluded.

Preferably, it is in the context of the invention so that the spring force of the first spring is less than the spring force of the second spring. In principle, however, it is also possible that the spring forces of the two springs are equal or even the spring force of the second spring is greater than the spring force of the first spring. It is crucial, above all, that the distribution of the spring forces on two springs in comparison to a tumbler, in which only one spring is provided, leads to only a reduced spring force acting on the first tumbler part.

In a preferred embodiment of the invention, the release slide is arranged in or within the bolt. For this purpose, the latch on a sliding channel which is open at the end to allow actuation of the trigger slide, but otherwise the sides surrounding the trip slider. Ultimately, the trip slider is protected by the circulating or closed in the direction of displacement channel. Unlike in the case of a release slide which is exposed on the outside of a latch, in the embodiment according to the invention it is not possible for the function of the release slider to be impaired during the movement along the latch or within the displacement channel.

The orientation is provided in the lock according to the invention that the first tumbler part and also the second tumbler part are spring-loaded transversely to the direction of movement of the trigger slide and movable. The Federbelastungsrichtung thus extends in or parallel to the direction of the longitudinal axis of the lock or lock housing and is - based on the installed state of the lock - directed downwards or towards the lower end of the lock housing.

In order to actuate the first tumbler part for releasing the locking of the bolt, it is provided in a preferred embodiment of the invention that on the first tumbler part a ramp for cooperation with the rear end of the trigger slide is provided. Constructively, the trigger slide at its rear end to this a rounded corner, with which he hits upon actuation, that is, upon movement of the trigger slide in the direction of the first tumbler, on the slope and the first tumbler thus against the spring force of the first spring transversely to Movement direction of the shutter slide moves. It is understood that the slope of the first locking member and the displacement of the trigger slide are chosen so that the Zuhaltungsvorprung provided on the first tumbler projection is disengaged from the tumbler housing provided on the tumbler opening, so that the Zuhaltefunktion is canceled.

In order to ensure the correct function of the tumbler according to the invention, even when the lock is actuated by the PC finger of a profile cylinder inserted in the lock, a special interaction of the first and the second tumbler part is necessary according to the invention. It is inventively provided that the first tumbler part and the second tumbler part are arranged in the region of the bolt or on the bolt, that upon actuation of the second tumbler against the spring load of the second spring, the second tumbler part on the first tumbler to release the blocking of the bolt acts. Finally, the two tumblers are arranged one behind the other in the manner of a series connection, after actuation of a profile cylinder, first the second tumbler is moved over the PZ-finger and this then acts on the first tumbler to cancel the Zuhaltungsfunktion. Thus, the second tumbler pushes the first Zuhaltsteil more or less.

Since the PZ-finger covers a comparatively large distance in the longitudinal direction of the lock and thus in the direction of movement of the tumbler when actuated by a key, a relatively large tumbler opening in the lock housing is required per se. However, the large tumbler opening also means that the trigger slide when operated by the bolt ejector must travel a relatively large way to move the first tumbler transverse to the direction of movement of the trip slider and the tumbler projection to bring out of engagement with the tumbler in the lock housing. In order not to let the displacement of the first tumbler part too large, the first tumbler part and the second tumbler part in the excluded state are spaced apart from each other over a defined gap. This gap preferably has at least a width of 1 mm. The gap between the two tumbler parts ultimately means that the two tumbler parts are moved or moved differently far when triggering the tumbler on a profile cylinder. Thus, in the solution according to the invention, the movement path of the second tumbler part is greater than the movement path of the first tumbler part due to the clearance.

In order to operate the release slide on the latch ejector safely, the release slide is in the excluded state of the bolt with its front end on the front edge of the bolt over. Based on the installed state of the lock, the front end of the release slide is thus over in the direction of the mating box or from the lock housing. This supernatant has the consequence that the latch ejector of the counter box initially acts on the front end of the trip slider with appropriate operation, before the bolt ejector meets the leading edge of the bolt.

In view of the projection of the release slider over the front edge of the bolt, the lifting of the tumbler function over the profile cylinder would cause the latch to be moved to the locked position, but the latch would still protrude beyond its front edge in the locked state of the latch , To prevent this, it is provided in a preferred embodiment of the invention that the first tumbler part a further slope is provided for cooperating with a provided at the rear end of the trigger slide projection to collect the trip slider. The further bevel is in this case formed on the first tumbler part such that, upon movement of the first tumbler part against the spring action of the first spring, the projection provided at the rear end of the trigger slide is moved along the further bevel and drawn in as a result, preferably so far. that it no longer protrudes beyond the front edge of the bolt in the retracted state.

In the invention, the two tumbler parts are coupled to the locking body, in such a way that during a movement of the locking body, the two tumbler parts are moved along. Specifically, it is related to the first guard locking part provided that at the end in the bolt or bolt body a transversely aligned to the direction of movement of the trigger slide recess for arranging the first spring and guide the first tumbler part are provided. The aforementioned recess thus has a double function. On the one hand, it serves to receive the first spring and at least part of the first guide part. Furthermore, the recess also has a guide function for the first tumbler part, so that it can be moved defined in and against the spring force of the first spring.

In a preferred embodiment, a passage opening is provided in the other end of the bolt or in the locking body through which a tumbler projection of the first tumbler is passed, so that the tumbler projection can cooperate with the lock housing or the tumbler opening provided there.

To couple the bolt or bolt body with the second tumbler part, a spring receptacle oriented transversely to the direction of movement of the trigger slider is provided at the end in the bolt to arrange the second spring. For mounting, the second spring, which is designed in particular as a helical spring, is inserted into the spring receiver. For coupling with the second tumbler part, a pin for engaging in or for supporting the second spring is provided thereon.

In order to be able to sufficiently guide the second tumbler part on the bolt or latch body, in a preferred embodiment, a guide projection is provided on the latch for engagement in a slot oriented transversely to the direction of movement of the trigger slider on the second tumbler part. It is understood that alternatively or additionally, the guide projection can in principle also be provided on the second tumbler part, while the slot is correspondingly provided on the latch as needed. In any case, a defined, guided movement of the second tumbler part is realized relative to the bolt or latch body by the combination of the guide projection and the slot.

In connection with the present invention, it is provided in a further preferred embodiment that the release slide is held by means of a releasable securing element on the bolt, that the securing element with closed lock housing is detachable from the outside and that the trigger slide can be removed from the front of the bolt when the lock housing is closed.

In connection with the invention it has been recognized that a lock of the type mentioned, which is provided in part of a lock assembly together with a mating box and for use in double-leaf doors, is basically also suitable for single-leaf doors. So far, it has been assumed that the use of such a lock, which is intended for double-leaf doors, for use in single-leaf doors is out of the question. Although the shutter slide is movable in the known castle, but he is permanently connected to the bolt. In the known lock the release slide is not readily apparent from the lock housing. A disassembly of the release slide is only possible if the lock housing opened, removed the release slide and the lock housing is then closed again. However, this is associated with a considerable amount of work and time, which has led to the lock manufacturers so far locks have always been kept for single-leaf and locks for double-leaf doors.

The invention now makes it possible to use a lock of the type mentioned in both single- and double-leaf doors, without a great effort would be necessary to mount the shutter slide or dismantle. If the lock according to the invention is used in a two-leaf door, the release slide is held securely on the latch by means of the securing element. The fuse element allows the longitudinal displacement of the release slide, but prevents the release slide can be removed from the bolt or lock housing. However, if the lock is to be used with a single-leaf door, the securing element can be removed from the outside of the lock, ie with the lock housing closed, and also with the lock housing closed on the front side from the latch or from the lock housing from the forend side.

Preferably, the lock according to the invention is manufactured and kept in the form by the manufacturer, which are more strongly removed by the purchaser of the manufacturer. This means that subsequent retrofitting is only necessary for the smaller part of the locks.

In order for the securing element to be able to fulfill its securing function with respect to the trigger slide, in a preferred embodiment of the invention, the securing element projects into the path of movement of the trigger slide. It is particularly preferred in this context that the securing element is detachably connected in the region of the movement path with the bolt.

In a preferred embodiment of the invention, at least one recess is provided on the trigger slide, which may have an elongated rectangular shape per se, the length of which corresponds at least to the path of movement of the trigger slide. In the region of the recess then engages the fuse element. The recess, which may be a cutout or a slot, ultimately ensures the displaceability of the release slide. The front side or front edge of the bolt facing away from the end of the recess in this case represents the stop for the securing element, thereby preventing the release slide can be pulled out of the sliding channel to the front.

In particular, in connection with the recess described above, it makes sense that in the region of the recess of the trigger slide a mounting hole in the bolt is provided for inserting and securing the securing element. The arrangement of this mounting hole and the insertion of the fuse element in the mounting hole, which is located in the path of movement, it is ultimately ensured that the stop function of the fuse element is guaranteed in each case.

Moreover, it is due to mounting reasons that the trigger slider is mirror-symmetrical with respect to its central longitudinal axis. This mirror symmetry may, but not necessarily, extend to the recess. This means that in principle only one, but in principle two recesses can be provided on opposite sides of the central longitudinal axis of the release slide, although only one recess is effective after the assembly of the trigger slide or cooperates with the fuse element.

In order to operate the fuse element from the outside of the castle ago, this end has an operating end. This actuating end ultimately serves to attach a tool for releasing the securing element. The securing element may preferably be a screw or else a detent pin. When using a screw, the operating end may be formed as a slot, Phillips or hexagon socket on a screw head. Basically, a headless screw, so a grub screw, with a slot, Phillips or a hexagon socket is possible.

In order to ensure access to the securing element or the actuating end of the securing element from the outside of the lock, an access opening for inserting a tool for releasing the securing element is provided in the lock housing. In this case, it is preferably the case that the access opening is aligned, in particular in the enclosed state of the bolt, with the actuating end of the securing element. This preferred embodiment ultimately has the consequence that the bolt must be completely enclosed and only in the locked state of the bolt, the securing element can be solved via the access opening.

In principle, however, it is also possible for the access opening in the excluded state of the bolt to be aligned with the actuating end of the securing element. Even in intermediate positions between the enclosed and the excluded state of the bolt, a loosening of the securing element can be provided. Accordingly, the access opening should be adapted to this.

In another preferred embodiment, it is advisable that the access opening is formed as a slot opening, which allows access to the operating end of the fuse element both in the enclosed and in the excluded state.

Other features, advantages and applications of the present invention will become apparent from the following description of exemplary embodiments with reference to the drawing and the drawing itself. In this case, all described and / or illustrated features, alone or in any combination, the subject of the present invention, regardless of their Summary in the claims or their dependency.

In the Fig. 1 to 4 is a part of a lock 1 according to the invention, which in the present case is a panic lock, ie a lock with a panic function is shown. The lock 1 is intended for installation in a door and ultimately belongs to a lock arrangement, not shown in detail, which in addition to the lock 1 has a mating box, not shown.

The lock 1 has a lock housing 2, which in turn comprises a lock case 3, a lock cover 4 and a forend 5. In the lock housing 2, which has an elongated rectangular shape with a longitudinal axis L, there is the lock mechanism, which as an integral part of a generally divided split nut 2, which is not shown in detail, has. Moreover, the lock 1, a latch 6, which in the Fig. 1 and 3 excluded and in the Fig. 2 and 4 is included. Not shown is also provided in the lock housing 2 case.

In the lock housing 2, moreover, there is an opening 7 for a profile cylinder. The opening 7 is adapted to the shape of a profile cylinder known from the prior art. The profile cylinder has, as is also known from the prior art, a PZ-finger, which is movable on actuation of the profile cylinder via a key.

Furthermore, the lock 1 has a tumbler 8, which in each case has a tumbler projection 9, 10 on opposite sides. To the tumbler projections 9, 10 correspond in the lock case 3 and the lock cover 4 each tumbler openings 11, 12, each having a stepped engagement 13, 14 have. When the tumbler projections 9, 10 are in the engagements 13, 14, the tumbler function is effective because the latch 6 can not be moved from the locked position to the locked position. If, however, the tumbler projections 9, 10 are moved out of the interventions 13, 14, it is possible to lock in the bolt 6.

In order to remove the tumbler function or to move the tumbler projections 9, 10 out of the interventions 13, 14, two functions or possibilities are provided. First, the tumbler 8 can be moved accordingly over the profile cylinder, not shown. By key operation of the profile cylinder of the PZ-finger of the profile cylinder is pivoted. In this case, this then acts on the tumbler 8, which leads to the corresponding movement of the tumbler 8, so that the tumbler projections 9, 10 are moved out of the interventions 13, 14.

To realize the other possibility, a release slide 15 is provided, which cooperates with the tumbler 8. For this purpose, a force in the direction of arrow 16 is exerted on the trigger slide 15. This is usually done via a latch ejector of the counter box. If the trigger slide 15 correspondingly far shifted in the direction of arrow 16, the tumbler projections 9, 10 are also disengaged from the interference 13, 14, so that the tumbler function is also canceled.

It is essential that the tumbler has at least two mutually separate tumbler parts, namely a first tumbler part 17 and a second tumbler part 18. The first tumbler part 17 is spring-loaded by a first spring 19, while the second tumbler part 18 is spring-loaded by a second spring 20. The two tumbler projections 9, 10 are provided on the first tumbler 17. As can be seen for example Fig. 7 Otherwise, what is not specifically shown, the spring force of the first spring 19 is less than the spring force of the second spring 20th

The selected design of the tumbler 8 with the two separate tumblers 17, 18 causes both tumbler parts 17, 18 are actuated separately from each other, wherein upon actuation of the first tumbler 17 only over the trigger slide 15, only the spring force of the first spring 19 are overcome must, but not the spring force of the second spring 20 or even the spring forces of the two springs 19, 20.

The latch 6 has a latch body 21, as in the Fig. 16 to 18 is shown. The bolt 6 thus forms with the locking body 21, the two tumblers 17, 18 and the two springs 19, 20 and the trigger slide 15 a locking unit, in and against the direction of the movement arrow 22 in the installed state in the enclosed and excluded position and vice versa is movable. The release slide 15 is guided longitudinally movable in the locking body 21 in the direction of movement of the bolt 6, that is, in the direction of the movement arrow 22. For this purpose, the locking body 21 has an open end, the tripping slide 15 but otherwise on all sides surrounding displacement channel 23. The locking body 21 is a casting in which the displacement channel 23 is provided.

The first tumbler part 17 and the second tumbler part 18 are spring-loaded transversely to the direction of movement of the trigger slide 15 and movable, as indicated by the movement arrow 24.

At the first tumbler 17 a ramp 25 is provided which cooperates with the rear or inner end 26 of the trigger slide 15. The release slider 15, which basically has a rectangular bar shape, has at its end 26 rounded corners 27 in order to cooperate with the ramp 25. For example, in Fig. 7 illustrated that the corner 27 acts on the upper portion of the ramp 25.

As is apparent from the drawing, the first tumbler 17 and the second tumbler 18 are arranged in the rear region of the latch body 21, in such a way that upon actuation of the second tumbler 18 via the profile cylinder, not shown, against the spring load of the second spring 20th the second tumbler 18 acts on the first tumbler 17 to release the locking of the latch 6.

Moreover, results in particular from the 8 and 9 in that when the tumbler 8 is triggered via the second tumbler part 18, that is to say when triggered via the PZ finger of the profile cylinder, the movement path of the first tumbler 17 for releasing the tumbler 8 is smaller than the movement distance of the second tumbler part 18. Specifically, this is provided for, that in the excluded state, as in Fig. 8 is shown, a gap 28 between the two tumbler parts 17, 18 is provided, over which the two tumbler parts 17, 18 are spaced from each other. The gap 28 has a width of greater than 1 mm. It is not just a possible game between the two Zuhaltsteilen 17, 18.

As can be seen from individual figures, the release slide 15 is in the excluded state with its front end 29 and in particular its front end edge 30 in the excluded state on the front edge 31 of the bolt 6 via. This makes it possible that the latch ejector of the associated counter box first encounters the front end 29 and the end edge 30 of the release slide 15 during its movement in the direction of the latch 6.

How, for example, from the Fig. 13, 15 and 21 results in the first tumbler 17 in addition to the ramp 25, a further slope 32 which is provided for cooperation with a located at the rear end of the trigger slide 15 projection 33. The further slope 32, which cooperates with the projection 33, serves to the trigger slide 15 in the latch. 6 or retract the latch body 21, and that is when the inclusion of the bolt 6 takes place via the profile cylinder. The formation of the slope 32 in conjunction with the projection 33 cooperating with the bevel 32 is such that the release slide 15 in the retracted state, as in Fig. 15 is shown, does not project beyond the front edge 31. Im in Fig. 15 illustrated embodiment, the front end edge 30 of the trigger slide 15 is aligned with the front edge 31 of the latch body 21.

As is otherwise the case, for example Fig. 15 , but also from the FIGS. 25 and 26 results, is located on the trigger slide 15 on at least one longitudinal side, in the illustrated embodiment, on both longitudinal sides, in each case a guide projection 34 to ensure a secure guidance of the trigger slide 15 within the displacement channel 23. The displacement channel 23 is, as this particular from Fig. 17 results, adapted from its cross-section to the cross-sectional shape of the trigger slide 15, so that a substantially backlash-free displacement of the trigger slide 15 in the displacement channel 23 is possible.

End is located in the locking body 21 a transversely to the direction of movement corresponding to the movement arrow 22 of the trigger slide 15 aligned recess 35, which serves to arrange the first spring 19 and to guide at least a portion or portion of the first tumbler 17. In addition to the recess 35 adjacent to the rear end of the locking body 21 is located in the locking body 21 a likewise transversely to the direction of movement of the trigger slide 15 aligned spring receptacle 36, which serves to arrange the second spring 20. The second spring 20 is inserted into the spring receptacle 36. In the case of the two springs 19, 20, in each case in the exemplary embodiment, these are in each case helical springs.

While a blind hole 37 for at least partially receiving a portion of the first spring 19 is provided on the ramp bevel 25 opposite end of the first tumbler 17, located on the second tumbler 20, a pin 38 for engagement in the second spring 20th

While the first tumbler part 17 is ultimately arranged and guided within the latch body 21 in the recess 35, the second tumbler part 18 is merely attached to or attached to the latch body 21. To guide the second tumbler 18 is located on the latch body 21, a guide projection 39, which is aligned in a transversely to the direction of movement of the trigger slide 15 aligned slot 40 engages the second tumbler 18. In addition, a projection 41 on the second tumbler part 18 is provided following the pin 38, which also engages in the spring seat 36 and serves to guide the second tumbler part 18. Moreover, the second tumbler part 18 next to the pin 38 and adjacent to this a stop 42 which is provided for cooperation with the lower end face 43 of the first tumbler part 17.

In the Fig. 5 to 9 is the trigger slide 15 each in the excluded state. The release slide 15 stands with its outer end 29 and its end edge 30 via the front edge 31 of the locking body 21 and the bolt 6 via. The rear end 26 of the trigger slide 15 abuts with the rounded corner 27 at the upper end of the ramp 25. This situation is also the case in the 8 and 9 shown states of the bolt 6, wherein in these embodiments, a difference in that consists in the in Fig. 8 shown state between the stop 42 of the second tumbler part 18 and the lower end face 43 of the first tumbler part 17 of the gap 28 is provided. The opposite is the in Fig. 9 illustrated state of the stop 42 on the front side 43 directly. However, in this state, the first tumbler 17 has not yet been moved by the second tumbler 18. The fact that the second tumbler part 18 has moved in the direction of the first tumbler part 17 is due to the fact that the profile cylinder is already pressed onto the active surface 44 at the lower end of the second tumbler part 18 via the PZ finger, not shown, and thus the second tumbler part 18 in the direction has moved to the first tumbler 17.

In the actuated state relative to the release slide 15, this is either pressed into the locking body 21 via the latch ejector of the counter box assigned to the lock 1 (this is described in FIGS 10 to 12 shown), or the trigger slide 15 is pulled over the slope 32 in connection with the projection 33 in the locking body 21, as shown in the Fig. 13 to 15 is shown.

In the in the 10 to 12 illustrated embodiment, the trigger slide 15 is pressed in the direction of the movement arrow 22 in the locking body 21, wherein the first tumbler 17 is then moved due to the interaction of the rounded corner 27 with the ramp 25 upwards. The horizontal movement of the trigger slide 15 is converted into a vertical movement of the first tumbler 17. At the same time the tumbler projections come 9, 10 out of engagement with the interventions 13, 14 of the tumbler openings 11, 12. The tumbler function is thus repealed and the latch 6 can be guided via the latch ejector and / or spring-loaded in the enclosed position.

If the tumbler function is ultimately to be released via the profile cylinder, the PZ finger of the profile cylinder initially acts on the active surface 44 at the lower end of the second tumbler part 18. This is then moved against the spring force of the second spring 20, bridging the gap 28. Subsequently, the stop 42 abuts against the lower end face 43 of the first tumbler part 17. The further movement of the PZ finger causes both tumbler parts 17, 18 are moved against the spring force of the two springs 19, 20. At the same time due to the interaction of the projection 33 on the trigger slide 15 with the slope 32 of the trigger slide 15 is retracted until the front end edge 30 is aligned with the front edge 31 of the latch body 21. At the same time the tumbler projections 9, 10 are moved out of the interventions 13, 14, so that the latch 6 is moved under spring load from the excluded to the enclosed position.

In the illustrated embodiments, it is otherwise the case that the trigger slide 15 is held by means of a releasable securing element 45 on the latch 6. The securing element 45 can be released from the latch 6 when the lock housing 2 is closed. Insofar is exemplified on the Fig. 4 directed. The possibility of releasability of the securing element 45 from the latch 6 has the result that the release slide 15 can be removed from the latch 6 when the lock housing 2 is closed, specifically from the front or front edge 31 of the latch 6 or the latch body 21.

As can be seen for example Fig. 7 results, the securing element 45 extends into the path of movement of the trigger slide 15. In this area, the securing element 45 with the latch 6 and the latch body 21 is detachably connected. In this context, a recess 46 is provided on the trigger slide 15, in which the securing element 45 engages. The length of the recess 46 corresponds at least to the path of movement of the trigger slide 15. In Fig. 7 a state is shown in which the rear end of the recess 46 abuts the securing element 45 and thus limits the exclusion movement in the direction of the movement arrow 22. In the region of the recess 45 of the trigger slide 15 is a mounting hole 47 in the bolt 6 and the bolt body 21 for Inserting and securing the securing element 45 is provided. In the illustrated embodiments, the attachment opening 47 is a threaded opening.

The trigger slide 15 may be mirror-symmetrically related to its central longitudinal axis. In Fig. 25 is a solid line 46 and a dashed line a possible opposite recess 46 shown. The mirror-symmetrical about the central longitudinal axis training has the advantage that during assembly of the trigger slide 15, so when inserting into the displacement channel 23, not to pay attention to the orientation of the trigger slide 15.

In the illustrated embodiment, the securing element 45 is formed as a screw having a screw head 48. The screw head 48 is provided with a hexagon socket 49. It is understood that the screw head 48 can basically also have a slot or a cross slot or that the screw is designed as a grub screw. The realization of a locking pin as a securing element 45 is possible.

In the lock housing 2 is an access opening 50 for attaching a tool for releasing the securing element 45. Specifically, the access opening 50 is provided in the illustrated embodiment in the castle ceiling 4 (see. Fig. 3 ), while it is understood that the access opening 50 may also be provided in the area of the lock case 3. As it turned out Fig. 4 results, the access opening 50 is aligned in the enclosed state of the bolt 6 with the screw head 48 of the securing element 45.

Not shown, but in principle it is also possible to form the access opening 50 as a slot, which extends over the entire path of movement of the mounting hole 47 in the latch 6 and in the latch body 21. In this way it is possible, the trigger slide 15 not only in the enclosed position accordingly Fig. 4 but also in the excluded position accordingly Fig. 3 to solve and remove from the displacement channel 23 to the front.

To replace the trigger slide 15, the latch 6 is first brought into its enclosed position, as in Fig. 4 is shown. The release slide 15 stands with its front end edge 30 is not on the front edge 31 of the bolt 6 via, but is at least substantially aligned with this. It then results in the Fig. 4 illustrated state in which the screw head 48 is aligned with the access opening 50. Alignment in this context means that the screw head 48 is accessible via the access opening 50 with a tool, so that after loosening the securing element 45, this can be removed from the access opening 50. After loosening and removing the securing element 45, there is no need for a stop for the trigger slide 15, which can then be removed from the front side of the bolt 6. This can - in the absence of the protrusion 33 - by shaking the lock 1 and / or by the self-weight of the release slide 15 at oblique position of the lock 1 or also take place in that the bolt 6 is excluded, so that in turn the in Fig. 3 shown state, in which case the front end 29 of the trigger slide 15 projects, so that the trigger slide 15 taken at the front end 29 and can be pulled out of the displacement channel 23.

If the lock 1 has no release slide 15, the assembly is carried out with the lock housing 2 closed in such a way that the release slide 15 is initially pushed completely into the excluded latch 6, which can then be moved into its enclosed position. In this position, then the securing element 45 can be screwed through the access opening 50 in the latch 6, which limits the trigger slide 15 in its movement forward and prevents in this way the removal of the trigger slide 15 to the front.

It is therefore crucial that the release slide 15 can be inserted from the front of the bolt 6 ago and then secured without the lock 1 and the lock housing 2 is to be opened as such.

In the inserted state, the replaceable trigger slide 15 fulfills its function in conjunction with the two-part tumbler 8 described above in that the first tumbler 17 assumes a controlling function via the ramp bevel 25 and the ramp 32 and pushes the trigger slide 15 in and out. In the front, excluded end position of the bolt 6 of the trigger slide 15 is held on the securing element 45, since this abuts the end of the recess 45. <B> LIST OF REFERENCES: </ b> 1 lock 28 gap 2 lock housing 29 The End 3 lock case 30 front edge 4 lock cover 31 leading edge 5 stulp 32 slope 6 bars 33 head Start 7 opening 34 guide projection 8th tumbler 35 recess 9 Zuhaltungsvorsprung 36 spring mount 10 Zuhaltungsvorsprung 37 blind 11 Zuhaltungsöffnung 38 spigot 12 Zuhaltungsöffnung 39 guide projection 13 intervention 40 Long hole 14 intervention 41 head Start 15 trip slider 42 attack 16 arrow 43 front 17 first locking part 44 effective area 18 second tumbler part 45 fuse element 19 first spring 46 recess 20 second spring 47 fastening opening 21 locking body 48 screw head 22 movement arrow 49 Allen 23 transfer channel 50 access opening 24 movement arrow 25 approach ramp L longitudinal axis 26 The End 27 corner
