Description

The invention relates to a lock with a bolt arranged in a lock housing, with a spring-loaded, at least one tumbler projection for interacting with the lock housing having tumbler and a release slide cooperating with the tumbler, the release slide being held on the bolt by means of a releasable securing element, the securing element is detachable from the bolt when the lock housing is closed and the release slide can be removed from the bolt when the lock housing is closed and the release slide is guided in the bolt in the locking direction of the bolt so as to be longitudinally movable in a sliding channel. The lock is preferably a panic lock.

A lock as part of a lock arrangement with a counter box for use in double-leaf doors is already known from practice. In a known lock arrangement for a double-leaf door, a lock with a bolt is located on one door, while a counter box with a bolt ejector is provided on the other door. The lock is usually a panic lock, that is, a lock with a panic function, which can also have a profile cylinder for locking. To implement the panic function, a release slide is provided on the lock that interacts with the guard locking of the lock and releases the guard locking when actuated. After releasing the guard locking, the spring-loaded bolt in the lock housing is moved from the locked position into the locked position. After locking the bolt, the door can then be opened easily.

The problem is that locks of the aforementioned type can ultimately only be used with double-leaf doors. For single-leaf doors, on the other hand, locks are used that lack a release slide, since single-leaf doors also lack a counter box. For the lock manufacturer, this means that different locks must be kept for single-leaf and double-leaf doors. This increases the production costs on the one hand, but also the storage costs on the other.

A generic lock is already from the WO 2010/016074 A1 known. The known lock has a release slide with an integrally molded threaded section. The threaded section can be screwed into a corresponding threaded hole in the bolt in order to cancel the locking of the bolt via the tumbler when the release slide is displaced. To remove the release slide from the bolt, a tool engages a screw head of the release slide on the faceplate side.
It is disadvantageous that the safety of the release slide is inadequate, especially with regard to manipulation by third parties.

The invention is therefore based on the object of providing a lock of the type mentioned at the outset which allows simple use in single and double-leaf doors and at the same time reliably securing the trigger slide, in particular against manipulation by third parties.

The aforementioned object is achieved according to the invention by a lock having the features of claim 1 and claim 9. Advantageous further developments are the subject of the corresponding subclaims.

In the lock according to the invention it is provided that the release slide is held on the bolt by means of a releasable locking element, that the locking element can be released from the outside when the lock housing is closed and that the release 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 at the outset, which is part of a lock arrangement together with an opposing box and for use with 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 provided for double-leaf doors, is out of the question for use in single-leaf doors. In the known lock, the release slide is movable, but it is permanently connected to the bolt. In the known lock, the release slide cannot be easily removed from the lock housing. The release slide can only be dismantled if the lock housing is opened, the release slide is removed 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 fact that lock manufacturers have always kept locks for single-leaf doors and locks for double-leaf doors.

The invention now makes it possible to use a lock of the type mentioned at the beginning of both single and double-leaf doors without the need for a great deal of effort to assemble or disassemble the release slide. If the lock according to the invention is used on a double-leaf door, the release slide is held securely on the bolt by means of the securing element. The securing element enables the release slide to be moved longitudinally, but prevents the release slide from being removed from the bolt or lock housing. However, if the lock is to be used on a single-leaf door, the securing element can be released from the outside of the lock, i.e. when the lock housing is closed, and can also be removed from the front of the bolt or the lock housing from the faceplate when the lock housing is closed.

The lock according to the invention is preferably produced and held by the manufacturer in the form that is more widely accepted by the manufacturer's customers. As a result, retrofitting is only necessary for the smaller part of the locks.

In the lock according to the invention, the release slide in the bolt or in the bolt body of the bolt is longitudinally movable in the direction of movement of the bolt, that is to say in and against the locking or locking movement of the bolt. On the one hand, this defines the direction of movement of the release slide, which is ultimately transverse to the longitudinal axis of the lock or lock housing; on the other hand, the longitudinally movable guidance and arrangement in the bolt body make it clear that the release slide moves together with the bolt when the bolt is closed. or is excluded.

The release slide is arranged in or within the bolt. For this purpose, the bolt has a displacement channel which is open at the end in order to enable actuation of the release slide, but which otherwise surrounds the release slide on all sides. Ultimately, the release slide is protected by the sliding channel that is closed all the way around or in the direction of rotation. In contrast to a release slide that is exposed on the outside on a locking side, it is not possible in the embodiment according to the invention for the function of the release slide to be impaired when moving along the lock or within the sliding channel.

So that the safety element can fulfill its safety function with respect to the release slide, it is provided that the safety element protrudes into the movement path of the release slide. It is particularly preferred in this context that the securing element is releasably connected to the bolt in the area of the movement path.

At least one recess is provided on the release slide, which itself can have an elongated rectangular shape, the length of which corresponds at least to the movement path of the release slide. The securing element then engages in the region of the recess. The recess, which can be a cutout or an elongated hole, ultimately ensures that the release slide can be moved. The end of the recess facing away from the front or front edge of the bolt represents the stop for the securing element, which prevents the release slide from being pulled forward out of the sliding channel.

In particular in connection with the recess described above, it is advisable that a fastening opening is provided in the bolt for inserting and fastening the securing element in the region of the recess of the release slide. The arrangement of this fastening opening and the insertion of the securing element into the fastening opening, which is located in the movement path, ultimately ensures that the stop function of the securing element is guaranteed in any case.

In addition, for reasons of assembly technology, it is advisable for the release slide to be mirror-symmetrical with respect to its central longitudinal axis. This mirror symmetry can, but does not necessarily have to, also extend to the recess. This means that basically only one, but in principle also two recesses can be provided on opposite sides of the central longitudinal axis of the release slide, although only one recess is effective or interacts with the safety element after the release slide has been installed.

In order to be able to actuate the securing element from the outside of the lock, the latter has an actuating end at its end. This actuating end is ultimately used to apply a tool to release the securing element. The securing element can preferably be a screw or a locking pin. When using a screw, the actuating end can be designed as a slot, cross-head or hexagon socket on a screw head. In principle, a headless screw, i.e. a grub screw, with a slot, cross recess or a hexagon socket is also possible.

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. It is the case here that the access opening is aligned with the actuating end of the securing element, particularly when the bolt is locked. this has Ultimately, the result is that the bolt must be completely enclosed and the securing element can only be released via the access opening in the locked state of the bolt.

In principle, however, it is also possible for the access opening to be aligned with the actuating end of the securing element when the bolt is in the locked state. Even in intermediate positions between the locked and locked state of the bolt, the securing element can be released. The access opening has to be adapted accordingly.

In another preferred embodiment, it is advisable for the access opening to be designed as an elongated hole opening which allows access to the actuating end of the securing element both in the enclosed and in the excluded state.

The present invention relates not only to a lock with a release slide, but also to a lock without a release slide. This lock is provided with a bolt arranged in a lock housing, with a spring-loaded, at least one tumbler projection for interaction with the lock housing identifying tumbler and a sliding channel on the bolt, designed for inserting a release slide that interacts with the tumbler, with a fastening opening in the area of the sliding channel for Insertion and fastening of a securing element is provided and an access opening for attaching a tool is provided in the lock housing, the access opening being aligned with the fastening opening, in particular when the bolt is locked.

In terms of its structural features, the aforementioned lock ultimately corresponds to the lock described above, although at least the release slide and, if necessary, the safety element are omitted.

Although a one-piece tumbler can in principle also be provided in the aforementioned lock - with or without a release slide - in a preferred embodiment of the invention it is provided that the tumbler is a first tumbler part spring-loaded with a first spring on which the at least one tumbler projection is provided , and has a second tumbler part which is spring-loaded by a second spring and which is separate from the first tumbler part, and that the release slide only acts on the first tumbler part.

In connection with the invention, it is preferred 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 for the spring forces of the two springs to be the same or even for the spring force of the second spring to be greater than the spring force of the first spring. Above all, it is crucial that the distribution of the spring forces between two springs, compared to a tumbler in which only one spring is provided, means that only a reduced spring force acts on the first tumbler part.

In the solution according to the invention, the one-piece tumbler in the prior art is divided into at least two tumbler parts that are separate from one another. Both tumbler parts are each acted upon by their own spring, the spring force of the first spring acting on the first tumbler part preferably being less to significantly less, namely at least by the factor 2 , in particular two to ten times less, than the spring force of the second spring. It is also the case that the release slide only acts on the first tumbler part, which is preferably less spring-loaded. This means that 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. In contrast, the spring force acting on the second tumbler part is preferably greater to much greater than the spring force of the first spring and can easily be selected so high that the PZ finger of the profile cylinder is not tilted and the panic function is prevented from blocking. However, the spring force of the second spring does not affect the function of the trigger slide or the triggering of the panic function via the bolt ejector of the counter box, since each of the tumbler parts is ultimately loaded by its own spring and can be operated independently.

As a result, the main advantage of the present invention is that the force required to move or lift the first tumbler part via the release slide is less than when lifting or actuating it via the second tumbler part. For this, it is crucial that the tumbler projection is provided on the first tumbler part, which can be actuated via the bolt ejector as well as the profile cylinder, whereas the second tumbler part has no blocking effect and is decoupled from actuation via the release slide. By dividing the single spring used in the prior art into two individual springs, on the one hand, only a lower force is required to trigger the panic function via the counter-box, and on the other hand, proper functioning of the panic function is guaranteed, since tilting between the PZ fingers and guard locking cannot occur due to the high spring force of the second spring.

With regard to the alignment, the lock according to the invention provides that the first tumbler part and also the second tumbler part are spring-loaded and movable transversely to the direction of movement of the release slide. The spring loading direction thus runs 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 in the direction of the lower end of the lock housing.

In order to actuate the first tumbler part to release the locking of the bolt, a preferred embodiment of the invention provides that a run-up bevel is provided on the first tumbler part to interact with the rear end of the release slide. In terms of design, the release slide has a rounded corner at its rear end with which, when actuated, i.e. when the release slide is moved in the direction of the first tumbler part, it strikes the incline and the first tumbler part thus crosses against the spring force of the first spring Moved direction of movement of the trigger slide. It goes without saying that the incline of the first tumbler part and the displacement path of the release slide are selected so that the tumbler projection provided on the first tumbler part disengages from the tumbler opening provided on the lock housing, so that the tumbler function is canceled.

In order to ensure the correct function of the tumbler according to the invention even when the lock is actuated by the PZ finger of a profile cylinder inserted into the lock, a special interaction of the first and second tumbler parts is necessary according to the invention. It is provided according to the invention that the first tumbler part and the second tumbler part are arranged in the area of the bolt or on the bolt such that when the second tumbler part is actuated against the spring load of the second spring, the second tumbler part on the first tumbler part to release the locking of the bolt works. Ultimately, the two tumbler parts are arranged one behind the other in the manner of a series connection, with the second tumbler part first being moved over the PZ finger after actuation of a profile cylinder and this then acts on the first tumbler part to cancel the tumbler function. The second tumbler part thus practically pushes the first tumbler part on.

Since the PZ finger covers a comparatively long distance in the longitudinal direction of the lock and thus in the direction of movement of the tumbler parts when actuated with a key, a relatively large tumbler opening in the lock housing is required. The large tumbler opening also means that the release slide has to cover a comparatively long distance when actuated by the bolt ejector in order to move the first tumbler part transversely to the direction of movement of the release slide and to bring the tumbler projection out of engagement with the tumbler opening in the lock housing. In order not to allow the displacement path of the first tumbler part to become too great, the first tumbler part and the second tumbler part are spaced apart from one another over a defined gap in the locked state. This gap is preferably at least 1 mm wide. The space between the two tumbler parts ultimately means that the two tumbler parts are displaced or moved differently when the tumbler is triggered via a profile cylinder. In the solution according to the invention, because of the gap, the movement path of the second tumbler part is greater than the movement path of the first tumbler part.

In order to be able to safely operate the release slide via the bolt ejector, the release slide protrudes with its front end over the front edge of the bolt when the bolt is in the locked state. In relation to the installed state of the lock, the front end of the release slide protrudes in the direction of the counter box or away from the lock housing. This protrusion has the consequence that the bolt ejector of the counter box, when actuated accordingly, first acts on the front end of the release slide before the bolt ejector hits the front edge of the bolt. In connection with the aforementioned feature of the protrusion of the release slide, it ultimately does not matter whether the tumbler is designed in one or two parts.

With regard to the protrusion of the release slide over the front edge of the bolt, the cancellation of the tumbler function via the profile cylinder would result in the bolt being moved into the locked position, but the release slide would still protrude beyond its front edge when the bolt is locked . In order to prevent this, a preferred embodiment of the invention provides that a further bevel is provided on the first tumbler part to interact with a projection provided at the rear end of the release slide in order to retract the release slide. The further bevel is formed on the first tumbler part in such a way that when the first tumbler part moves against the spring action of the first spring, the projection provided at the rear end of the release slide along the further incline is moved and subsequently drawn in, preferably so far that it no longer protrudes beyond the front edge of the bolt in the drawn-in state.

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

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

To couple the bolt or bolt body to the second tumbler part, a spring receptacle is provided at the end of the bolt, which is oriented transversely to the direction of movement of the release slide, for the arrangement of the second spring. For assembly, the second spring, which is designed in particular as a helical spring, is then inserted into the spring receptacle. For coupling to the second tumbler part, a pin is provided on the latter for engaging in or for mounting the second spring.

In order to be able to adequately guide the second tumbler part on the bolt or bolt body, a guide projection is provided on the bolt in a preferred embodiment for engaging in an elongated hole on the second tumbler part oriented transversely to the direction of movement of the release slide. It goes without saying that, as an alternative or in addition, the guide projection can in principle also be provided on the second tumbler part, while the elongated hole is then provided on the bolt corresponding to this, if necessary. In any case, the combination of the guide projection and the elongated hole realizes a defined, guided movement of the second tumbler part relative to the bolt or bolt body.

In the 1 to 4th is part of a lock according to the invention 1 , which in the present case is a panic lock, i.e. a lock with a panic function. The lock 1 is intended for installation in a door and ultimately belongs to a lock arrangement, not shown in detail, which is next to the lock 1 has a counter box, not shown.

The lock 1 has a lock housing 2 on, which in turn is a lock case 3 , a castle ceiling 4th and a faceplate 5 includes. In the lock housing 2 , which is an elongated rectangular shape with a longitudinal axis L. has, is the lock mechanism, which is an essential part of the rule 2 split lock follower, which is not shown in detail, has. Otherwise, the lock 1 a latch 6th on that in the 1 and 3 excluded and in the 2 and 4th is included. One is also not shown in the lock housing 2 intended trap.

In the lock housing 2 there is also an opening 7th for a profile cylinder. The opening 7th is adapted to the shape of a profile cylinder known from the prior art. As is also known from the prior art, the profile cylinder has a PZ finger which can be moved using a key when the profile cylinder is actuated.

Furthermore, the lock 1 a guard 8th on, the present on opposite sides each have a tumbler projection 9 , 10 having. To the guard locking protrusions 9 , 10 correspond in the lock case 3 and the castle ceiling 4th each tumbler openings 11 , 12 each having a graduated engagement 13 , 14th exhibit. When the tumbler protrusions 9 , 10 in the interventions 13 , 14th the guard locking function is effective because the bolt 6th cannot be moved from the locked position to the locked position. Become the guard locking tabs 9 , 10 however, from the interventions 13 , 14th moved out is a locking of the latch 6th possible.

To cancel the guard locking function or the guard locking projections 9 , 10 from the interventions 13 , 14th to move out, two functions or possibilities are provided. On the one hand, the guard locking 8th be moved accordingly via the profile cylinder, not shown. The profile cylinder's PZ finger is swiveled when the profile cylinder is keyed. This then acts on the guard locking 8th what causes the corresponding movement of the guard locking 8th leads so that the tumbler projections 9 , 10 from the interventions 13 , 14th be moved out.

The other option is to use a release slide 15th provided with the guard locking 8th cooperates. To do this, a force is applied in the direction of the arrow 16 on the release slide 15th exercised. This is usually done using a bolt ejector on the counter box. Becomes the trigger slide 15th correspondingly far in the direction of the arrow 16 shifted, the tumbler protrusions come 9 , 10 also out of engagement with the interventions 13 , 14th so that the guard locking function is also canceled.

In the illustrated embodiments it is provided that the tumbler 8th has at least two separate tumbler parts, namely a first tumbler part 17th and a second tumbler part 18th . The first locking part 17th is from a first spring 19th spring-loaded while the second tumbler part 18th from a second feather 20th is spring loaded. There are on the first guard locking part 17th the two tumbler projections 9 , 10 intended. How, for example, from 7th results, the release slide acts 15th only on the first guard locking part 17th . In addition, what is not specifically shown is the spring force of the first spring 19th less than the spring force of the second spring 20th .

The selected design of the guard locking 8th with the two separate guard locking parts 17th , 18th leads to both guard locking parts 17th , 18th can be actuated separately from one another, with the actuation of the first tumbler part 17th only via the release slide 15th only the spring force of the first spring 19th must be overcome, but not the spring force of the second spring 20th or even the spring forces of the two springs 19th , 20th .

It should be expressly pointed out that the invention specified in the general part of the description is not limited to the use of a two-part tumbler, even if this is not shown in detail. If the guard locking consists of a single component, only one guard locking spring is provided. In the following to be described in detail Interchangeability of the release slide 15th this does not change anything.

The latch 6th has a locking body 21st on how he's in the 16 to 18th is shown. The latch 6th thus forms with the bolt body 21st , the two guard locking parts 17th , 18th and the two springs 19th , 20th as well as the release slide 15th a locking unit that goes in and against the direction of the movement arrow 22nd is movable in the installed state in the enclosed and excluded position and vice versa. The trigger slide 15th is in the bolt body 21st in the direction of movement of the bolt 6th , that is in the direction of the movement arrow 22nd longitudinally movable out. For this purpose, the locking body 21st an open end, the release slide 15th but otherwise all-round surrounding displacement channel 23 on. With the bolt body 21st it is a cast part in which the sliding channel 23 is provided.

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

On the first guard locking part 17th is a ramp 25th provided with the rear or inner end 26th of the release slide 15th cooperates. The trigger slide 15th , which basically has a rectangular bar shape, has at its end 26th rounded corners 27 to with the approach slope 25th to be able to work together. For example, in 7th depicted that corner 27 on the upper area of the ramp 25th works.

As can also be seen from the drawing, the first tumbler part 17th and the second tumbler part 18th in the rear area of the bolt body 21st arranged in such a way that upon actuation of the second tumbler part 18th via the profile cylinder, not shown, against the spring load of the second spring 20th the second guard locking part 18th on the first guard locking part 17th to release the locking of the bolt 6th works.

In addition, results in particular from the 8th and 9 that when the guard locking is triggered 8th via the second guard locking part 18th , i.e. when triggered via the profile cylinder's PZ finger, the movement path of the first guard locking part 17th to release the guard locking 8th is smaller than the movement path of the second tumbler part 18th . Specifically, it is intended that in the excluded state, as described in 8th is shown, a space 28 between the two guard locking parts 17th , 18th is provided over which the two tumbler parts 17th , 18th are spaced from each other. The gap 28 has a width of more than 1 mm. So it is not just a possible play between the two tumbler parts 17th , 18th .

As can be seen from the individual figures, the release slide is in place 15th in the excluded state with its front end 29 and in particular its front edge 30th in the excluded state over the front edge 31 (Front) of the latch 6th over. This makes it possible for the bolt ejector of the associated counter box to move in the direction of the bolt 6th first on the front end 29 or the front edge 30th of the release slide 15th meets.

As can be seen from the 13 , 15th and 21st is located on the first guard locking part 17th in addition to the ramp 25th another slope 32 that cooperate with one at the rear end of the release slide 15th located protrusion 33 is provided. The further slope 32 that with the lead 33 cooperates, serves to the trigger slide 15th in the bolt 6th or the bolt body 21st to retract when the locking of the bolt 6th takes place via the profile cylinder. The formation of the slope 32 in connection with the one with the slope 32 cooperating lead 33 is such that the trigger slide 15th when retracted, as shown in 15th is shown, not across the leading edge 31 survives. In the in 15th illustrated embodiment is the front end edge 30th of the release slide 15th with the leading edge 31 of the bolt body 21st aligned.

As can be seen from the rest, for example 15th , but also from the 25th and 26th results, is located on the release slide 15th on at least one longitudinal side, in the illustrated embodiment on both longitudinal sides, each have a guide projection 34 to ensure safe guidance of the trigger slide 15th within the sliding channel 23 to ensure. The shift channel 23 is how this particular turns out 17th results, from its cross-section to the cross-sectional shape of the trigger slide 15th adapted, so that a substantially play-free movement of the release slide 15th in the shift channel 23 is possible.

The end is in the bolt body 21st one perpendicular to the direction of movement according to the movement arrow 22nd of the release slide 15th aligned recess 35 that is used to arrange the first spring 19th and for guiding at least a part or area of the first tumbler part 17th serves. Next to the recess 35 adjacent the rear end of the latch body 21st is located in the bolt body 21st one also transverse to the direction of movement of the release slide 15th aligned spring retainer 36 that are used to arrange the second spring 20th serves. The second feather 20th is in the spring receptacle 36 inserted. By the two springs 19th , 20th In any case, in the exemplary embodiment, it is a matter of coil springs.

While on the ramp 25th opposite end of the first tumbler part 17th a blind hole 37 for at least partially receiving part of the first spring 19th is provided, is located on the second tumbler part 20th a cone 38 to engage the second spring 20th .

While the first guard locking part 17th ultimately within the bolt body 21st in the recess 35 is arranged and guided, is the second tumbler part 18th to the bolt body 21st only attached or attached. For guiding the second guard locking part 18th is located on the bolt body 21st a leadership advantage 39 in a transverse to the direction of movement of the trigger slide 15th aligned elongated hole 40 in the second guard locking part 18th intervenes. In addition, it is following the tenon 38 a head start 41 on the second guard locking part 18th provided, which is also in the spring receptacle 36 engages and for guiding the second tumbler part 18th serves. Otherwise, the second tumbler part 18th next to the peg 38 or adjacent to this a stop 42 on that to interact with the lower end face 43 of the first guard locking part 17th is provided.

In the 5 to 9 is the trigger slide 15th each in the excluded state. The trigger slide 15th stands with its outer end 29 or its front edge 30th over the leading edge 31 of the bolt body 21st or the bolt 6th over. The back end 26th of the release slide 15th lies with the rounded corner 27 at the upper end of the ramp 25th at. This situation also applies to those in the 8th and 9 shown states of the bolt 6th before, there being a difference in these embodiments in that the in 8th shown state between the stop 42 of the second guard locking part 18th and the lower face 43 of the first guard locking part 17th The gap 28 is provided. On the other hand, the in 9 shown state of the stop 42 at the front 43 immediately. However, the first guard locking part is in this state 17th from the second guard locking part 18th not yet moved. That the second guard locking part 18th in the direction of the first guard locking part 17th has moved, is due to the fact that the profile cylinder is already on the active surface via the PZ finger, not shown 44 at the lower end of the second guard locking part 18th pressed and thus the second guard locking part 18th in the direction of the first guard locking part 17th moved.

In the actuated state related to the release slide 15th this is either via the bolt ejector of the lock 1 associated counter box in the bolt body 21st pressed in (this is in the 10 to 12 shown), or the release slide 15th becomes over the slope 32 in connection with the projection 33 into the bolt body 21st drawn into it like this in the 13 to 15th is shown.

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

If the guard locking function is ultimately to be released via the profile cylinder, the profile cylinder's PZ finger first acts on the active surface 44 at the lower end of the second guard locking part 18th . This is then initially bridging the gap 28 against the spring force of the second spring 20th emotional. Then the stop hits 42 on the lower face 43 of the first guard locking part 17th at. The further movement of the PZ finger causes both tumbler parts 17th , 18th against the spring force of the two springs 19th , 20th be moved. At the same time due to the interaction of the projection 33 on the release slide 15th with the slope 32 the release slide 15th drawn in until its front edge 30th with the leading edge 31 of the bolt body 21st is aligned. At the same time, the tumbler protrusions 9 , 10 from the interventions 13 , 14th moved out so that the latch 6th is moved under spring loading from the excluded to the locked position.

Before this is the guard locking 8th as a two-part guard locking with the first guard locking part 17th and the second tumbler part 18th has been described. As has already been stated in the general part of the description, this is a preferred embodiment. Basically, the guard locking 8th but also be made in one piece and acted upon by only one spring. Regardless of the type of training the guard locking is in the lock 1 in any case, provided that the release slide 15th by means of a detachable securing element 45 on the latch 6th is held. The security element 45 is with the lock housing closed 2 from the bolt 6th solvable. In this respect, the 4th referenced. The possibility of releasability of the securing element 45 from the bolt 6th has the consequence that the release slide 15th with the lock housing closed 2 from the bolt 6th can be removed from the front or front edge 31 of the bolt 6th or the bolt body 21st .

How, for example, from 7th results, the locking element protrudes 45 up to the movement path of the release slide 15th . The safety element is in this area 45 with the bolt 6th or the bolt body 21st releasably connected. In this context is on the release slide 15th a recess 46 provided in which the fuse element 45 intervenes. The length of the recess 46 corresponds at least to the movement path of the trigger slide 15th . In 7th is shown a state in which the rear end of the recess 46 on the fuse element 45 strikes and thus the exclusion movement in the direction of the movement arrow 22nd limited. In the area of the recess 45 of the release slide 15th is a mounting hole 47 in the bolt 6th or on the bolt body 21st for inserting and fastening the fuse element 45 intended. In the illustrated exemplary embodiments, it is the fastening opening 47 around a threaded opening.

The trigger slide 15th can also be mirror-symmetrical with respect to its central longitudinal axis. In 25th is a recess with a solid line 46 and with a dashed line a possible opposite recess 46 shown. The mirror-symmetrical design about the central longitudinal axis has the advantage that during the assembly of the release slide 15th , i.e. when inserting into the sliding channel 23 , not the orientation of the release slide 15th must be observed.

In the illustrated embodiment, the securing element is 45 designed as a screw that has a screw head 48 having. The screw head 48 is with a hexagon socket 49 Mistake. It goes without saying that the screw head 48 can in principle also have a slot or a cross slot or that the screw is designed as a grub screw. Also the implementation of a locking pin as a securing element 45 is possible.

In the lock housing 2 there is an access opening 50 for applying a tool to loosen the locking element 45 . The access opening is specific 50 in the illustrated embodiment in the castle cover 4th provided (cf. 3 ), while it is understood that the access opening 50 also in the area of the lock case 3 can be provided. How out 4th results is the access opening 50 in the locked state of the bolt 6th with the screw head 48 of the fuse element 45 aligned.

The access opening is not shown, but it is also possible in principle 50 to be designed as an elongated hole that extends over the entire path of movement of the fastening opening 47 in the bolt 6th or in the bolt body 21st extends. In this way it is then possible to use the release slide 15th not only in the locked position accordingly 4th but also in the excluded position accordingly 3 to be released and out of the sliding channel 23 to be removed from the front.

To replace the release slide 15th becomes the latch 6th first brought into its enclosed position, as shown in 4th is shown. The trigger slide 15th stands with its front edge 30th not over the leading edge 31 of the bolt 6th over, but is at least substantially aligned with it. The in 4th State shown in which the screw head 48 with the access opening 50 is aligned. Alignment means in this context that the screw head 48 via the access opening 50 is accessible with a tool, so that after loosening the securing element 45 this from the access opening 50 can be taken.

After loosening and removing the locking element 45 there is no stop for the release slide 15th that is then from the front of the latch 6th can be taken from here. This can - in the absence of the lead 33 - by shaking the lock 1 and / or by the dead weight of the trigger slide 15th when the lock is held at an angle 1 or by the fact that the bolt 6th is excluded, so that the in 3 shows the state shown, then the front end 29 of the release slide 15th protrudes so that the release slide 15th at the front end 29 taken and out of the sliding channel 23 can be pulled out.

Know the lock 1 no release slide 15th assembly takes place with the lock housing closed 2 such that the trigger slide 15th initially completely in the locked bolt 6th is inserted, which can then be moved to its enclosed position. In this position, the securing element can then 45 via the access opening 50 in the bolt 6th be screwed in what the release slide 15th in its forward movement is limited and in this way the removal of the release slide 15th forward prevented.

So it is crucial that the release slide 15th from the front of the latch 6th can be pushed in and then secured without the lock 1 or the lock housing 2 is to be opened as such.

When inserted, the replaceable release slide fulfills 15th its function in connection with the two-part guard locking described above 8th in that the first tumbler part 17th over the ramp 25th and the slope 32 takes over a controlling function and the release slide 15th pushes in and out. In the front, excluded end position of the bolt 6th is the release slide 15th via the fuse element 45 held because this is at the end of the recess 45 strikes.
