Description

The invention relates to a lock. The lock can also be referred to as a lock latch lock. In particular, it is a mortise lock for mounting on a door leaf.

Lockpick locks are known from the prior art. These have in addition to the trap (also referred to as the main trap) on a tax trap. In the closed position of the door, the control latch activates a latch, thereby locking the foregoing main latch against manipulative pushing back. The case lock is unlocked at the regular door opening by means of door handle or lock cylinder leading, in order then to allow the regular trapping of the main trap.

Furthermore, from the prior art locks are known in which the main trap is designed as a "turning trap". In this case, the case can be rotated 180 ° to use the door for a left or right stop. There are designs in which the latch is pushed into the lock box until it comes out of engagement with the forend and can be rotated.

However, it is a disadvantage of the prior art that a pivotal main latch can not be used in a prior art latch latch as the main latch would be blocked upon rotation on the latch, thus allowing this type of latch rotation inside the latch box Lock latch locks is not possible.

It is an object of the present invention to provide a lock that is easy to install and allows safe operation of a door.

The object is achieved by the features of the independent claim. The dependent claims relate to advantageous embodiments of the invention.

Thus, the problem is solved by a lock. The lock can also be referred to as a lock latch lock. In particular, the lock is designed as a mortise lock. The lock is designed in particular for a building door, in particular for a swing door. In particular, the lock comprises a lock case, which is also referred to as lock housing, and preferably a forend.

The lock includes a retractable main trap. The main trap is preferably linearly guided in the lock case. In particular, the main trap comprises a main trap head and a main trap stem. Preferably, the entire main trap, including Hauptfallenkopf and Hauptfallenschaft, or only the main case head, rotatable for a left and right stop. For this purpose, it is provided in particular that the lock case has a recess for rotation of the main case. In particular, the main trap can be pressed inwards until it comes out of engagement with the forend. The recess in the lock case allows the free space for the main case head during rotation through 180 °.

The lock further comprises a control catch arrangement. The control trap assembly includes a control case carrier and a control latch. The tax trap is located on the tax case carrier. The control case carrier in turn is preferably movable in the lock case guided, in particular fastened. The tax case carrier can z. B. a contour, in particular a slot, have, in which engages a projection of the lock box. The control case carrier is preferably linearly displaceable relative to the lock case.

In particular, the main trap is arranged linearly displaceable along a trap axis. The advantageously used main traction shank extends along this trapping axis. The control case carrier is preferably linearly movable parallel to the catch axis opposite or in the lock case.

In the open state of the door, in which the lock described here is arranged, the control catch protrudes just as the main trap on the forend to the outside. When the door is closed, the main latch projects into the corresponding opening in the strike plate of the door frame. The control catch is pressed inwards by the striking plate and actuates the control case carrier.

It is envisaged that the control case carrier is movable into the following three positions: (i) an extended position with the control latch extended; while the tax trap is on the forend to the outside. (ii) a retracted position with retracted tax trap; The tax trap is pressed inwards. (iii) An overstroke position, which will be explained in detail.

The retraction position is located along the direction of movement of the control case carrier between the extended position and the overstroke position. If the control case carrier is moved from the extended position, he first passes through the retraction position and at a further movement in the same direction then the overstroke position.

The lock further comprises a locking element. The blocking element is arranged in particular in the lock case. Particularly preferably, the blocking element is arranged rotatably relative to the lock case.

The blocking element can assume a blocking position in which it blocks retraction or depression of the main catch. Furthermore, the blocking element can assume a release position, in which the retraction or the depression of the latch is not locked and thus released. In particular, the blocking element is rotatable from the blocking position to the release position and vice versa.

The control case carrier is arranged for actuating the blocking element. In particular, the control case bearer directly contacts the blocking element and can thus move the blocking element. The "actuation" of the locking element by the control case carrier can also take place in conjunction with a blocking element spring, wherein the blocking element is moved in one direction of movement by the blocking element spring and the control case carrier "activates" the blocking element in that it releases the blocking element and not against the force the locking element spring stops.

1. (i) In der Ausfahrposition das Sperrelement die Freigabeposition einnimmt.
2. (ii) In der Einfahrposition das Sperrelement die Sperrposition einnehmen kann.
3. (iii) In der Überhubposition das Sperrelement wieder die Freigabeposition einnimmt.

The control case carrier is arranged for actuating the blocking element such that:

1. (i) In the extended position, the blocking element assumes the release position.
2. (ii) In the retracted position, the blocking element can assume the blocking position.
3. (iii) In the overstroke position, the locking element again assumes the release position.

The control case carrier is preferably in the extended position, in the retracted position and in the overstroke position within the lock case.

It is preferably provided that the main catch is movable between an extended position, a retracted position and an overstroke position, wherein the skin trap is rotatable in the overstroke position. In the extended position, the main trap protrudes in particular over the forend to the outside. The main trap occupies the extended position, especially when the door is open. In the retracted position, the main trap is retracted in particular. The retraction position preferably occupies the main catch during a door opening or door closing.

In particular, it is provided that in the retracted position of the control case carrier, the blocking element assumes the blocking position when the main case is in the extended position. The blocking element prevents a manipulative impressions of the main trap.

In particular, the control case carrier in the retracted position allows the blocking element to assume the blocking position. If the main catch protrudes outward beyond the forend and / or if it is in the extended position and the control case bearer is in the retracted position, the blocking element preferably occupies the blocking position. If the main case, in particular in the retracted position, withdrawn and the control case carrier is in the retracted position, the blocking element is preferably held in the release position by the main catch.

The main trap is in particular rotatable only in the overstroke position. The main latch may be out of engagement with the forend in the overstroke position.

The retraction position is located in particular along the direction of movement of the main trap between the extended position and the overstroke position.

The main trap, in particular the main trap head of the main trap, comprises in particular a blocking surface and an inclined surface, wherein in the overstroke position by the rotation of the main trap, the positions of the blocking surface and the inclined surface relative to the lock housing are interchangeable. In the overstroke position, the main trap is particularly out of engagement with a forend. In the overstroke position, the main trap is in particular completely withdrawn into the lock case.

The lock case preferably comprises the recess, wherein the main case is at least partially in the recess during rotation in the overstroke position.

If the control case carrier is moved starting from its extended position and the thus extended control latch, it first passes through its retracted position. In a further movement of the control case carrier in the same direction of movement of the taxpayer support his overstroke position. When taking the overstroke actuated and / or holding the control case carrier holds the blocking element in the release position. In the release position, the main catch can be rotated by 180 °.

In particular, during a movement of the control case carrier from the extended position and / or the retracted position into the overstroke position, the main catch can hold the blocking element in the release position. The control case carrier may preferably take over the holding of the locking element in the overstroke position. This eliminates the need for the main trap in the overstroke position of the control case carrier and / or in the overstroke position of the main trap to hold the blocking element in the release position. Thus, a rotation of the main case in the overstroke position is possible without a movement of the locking element in the locked position prevents or prevents the rotation.

In particular, the control case carrier is arranged and designed such that it can be moved into the overstroke position by pressing in the main catch. This is especially possible only if the control case carrier is initially in the extended position and thus the blocking element is in the release position.

For this purpose, it is provided in particular that the control case carrier comprises a driver, which is in operative connection with the main trap or can come into operative connection. In particular, it is provided that the driver protrudes to the main trap.

The main case head has a backside that points into the interior of the lock case. The driver of the control case carrier protrudes in particular at this back of the main case head.

If the main trap is pressed in, the back of the main case head hits the driver and thus shifts the entire control case carrier. As a result, the control case wearer first assumes his retracted position and then his overstroke position. In particular, it becomes a movement the blocking element is blocked in the blocking position by the skin trap head; the blocking element abuts in particular on the main case head and therefore can not pivot into its locking position.

Preferably, the main trap and the control case carrier are not only designed so that the main trap entrains the control case carrier up to the overstroke position, but also so that the skin trap holds the control case carrier in the overstroke position throughout its rotation in the overstroke position. As a result, the locking element remains in the release position throughout the rotation. As a result, the blocking element does not block the rotational movement of the main trap. In particular, the driver remains in operative connection, preferably contact, with the main trap while the main trap is rotated in its overstroke position.

Furthermore, it is preferably provided that the main latch comprises a holding means which always remains in operative connection, in particular in contact with the control case carrier, while the main latch is rotated in the overstroke position.

The holding means may in particular be an annular sliding surface for the driver. The holding means can rest in the overstroke position on the driver. The holding means may be arranged at the back of the main case head.

In a preferred embodiment, it is provided that the control case carrier and the blocking element each have an actuating surface.

The actuating surfaces can come into operative connection during the movement of the control case carrier from the retracted position to the overstroke position or be in operative connection with the blocking element in the release position while the taxpayer carrier is in the overstroke position. The two actuating surfaces can meet during the movement of the control case carrier from the retracted position to the overstroke position, so as to move the blocking element by the movement of the control case carrier in the release position. In particular, a rotation of the locking element takes place.

Alternatively, it can be provided that the actuating surfaces come into operative connection in the overstroke position, in particular, meet one another. The actuating surfaces may operatively cause retention of the locking member in the release position. In particular, the blocking element is already in the release position at the meeting of the actuating surfaces.

The lock preferably comprises a nut. The nut serves to receive a pusher or a doorknob. The nut has several nut arms. A nut arm is preferably arranged for actuating the blocking element. By turning the nut thus the nut arm can actuate the locking element, in particular turning. This unlocks the case lock during regular operation of the door. By turning the nut, the locking element can be moved from the locking position to the release position.

Preferably, the already mentioned locking element spring is provided. The blocking element spring moves the blocking element into its blocking position. The control case carrier is in particular designed such that it moves the blocking element against the force of the blocking element spring out of the blocking position, in particular pulls, so that the blocking element can assume its release position.

Also, the control case carrier is preferably spring loaded, so that it assumes its extended position in the non-actuated state. Also, the main case is preferably spring-loaded so that it is extended by the force of the corresponding main latch spring.

For the actuation of the locking element by the control case carrier there are in particular the following two variants:
According to a first variant, the control case carrier has a slide extension which slides on a guide surface of the blocking element in order to pull the blocking element into its release position. According to the second, reverse variant, the blocking element has a slide extension which slides on a guide surface of the control case carrier in order to pull the blocking element into its release position. In both variants, it is possible in a simple manner to convert the linear movement of the control case carrier into a rotational movement of the blocking element.

The guide surface may be configured to hold the blocking element in the release position in the extended position and / or in the overstroke position. The guide surface can serve as a stop to limit the particular spring-driven movement of the locking element in the locked position. The guide surface can be formed continuously. The guide surface may preferably be curved, particularly preferably concave. The combination of slide extension and guide surface can also be designed as a sliding guide.

Furthermore, it is preferably provided that the control latch is movable, in particular linearly movable, relative to the control carrier and in the or is arranged on the tax case carrier. In particular, the control catch is extended to a protruding position when the control case carrier is in the extended position, and / or retract to a retracted position when the control case carrier is in the retracted position or the overstroke position.

In the protruding position, the tax trap protrudes from the lock housing. The tax trap is extended in the protruding position. This is the case in particular when the door is open. In the retracted position the tax trap is withdrawn into the lock case. The tax trap is retracted in the retracted position. This is the case especially when the door is closed.

Thus, especially with the door closed, the control case carrier in the retracted position. When the door is open, the control case carrier is in particular in the extended position.

It is preferably provided that the control latch is connected to the control case carrier by means of a control latch spring, wherein by means of the control latch spring, the control latch is movable together with the control case carrier, in particular displaceable.

In particular, it is provided that the tax trap comprises a tax trap and a tax case header. The tax trap header is attached to the tax trap shaft. The tax traps are in the tax case carrier. The tax trap spring is arranged on the tax trap shaft.

Upon a movement of the control case carrier from the extended position to the retracted position, the control catch also becomes protruding Position moved to the retracted position. Upon movement of the control case carrier from the retracted position to the extended position, the control catch is simultaneously moved from the retracted position to the protruding position.

The control case carrier is movable against the force of the control latch spring from the retracted position to the overstroke position. In particular, the control latch remains in the retracted position while the control case carrier is moved to the overstroke position and / or is in the overstroke position.

Preferably, the control latch can be pulled against the force of the control latch spring in a mounting position, wherein the control latch is rotatable in the mounting position.

The control catch is in particular rotatable only in the mounting position. The control latch in particular comprises a blocking surface and an inclined surface, wherein in the mounting position by the rotation of the control latch, the position of the locking surface and the inclined surface relative to the lock housing are interchangeable.

In the mounting position, a control case head of the control latch is preferably out of engagement with the forend. In the mounting position of the tax case head is preferably pulled out of the forend. The protruding position of the control catch is particularly along the direction of movement between the mounting position and the retracted position. In the assembly position, the control case carrier preferably remains in the extended position.

The use of the control catch spring not only allows the control catch to be withdrawn and turned, but also allows the control striker to move to its overstroke position without pulling the head of the control catch inward out of its forend guide. The indented head of the taxpayer may remain within the cuff when the taxpayer carrier moves from its retracted position to the overstroke position by moving the taxpayer carrier against the force of the tax-damper spring.

Preferably, it is provided that the main latch occurs in a movement from the extended position into the retracted position in operative connection with the blocking element such that the main catch holds the blocking element in the release position.

Preferably, it is provided that the lock comprises a latch stop, wherein the latch stop between an operating position and a mounting position is movable, wherein in the operating position, the main case is in the retracted position in operative connection with the latch stop, so that the latch stop movement of the main trap in the Overstroke prevented, and in the mounting position, the main case is in the retracted position out of operative connection with the latch stop, so that the latch stop releases a movement of the main case in the overstroke position.

If the fall stop is in the operating position, the movement of the main catch from the extended position into the lock case into the retracted position is limited by means of the fall stop. The movement of the latch stop between the operating position and the mounting position can be done manually and / or by gravity. In particular, in the disassembled state of the castle Lock case are moved so that the latch stop is moved from the operating position to the mounting position. For example, the lock can be turned upside down, so that the movement of the fall stop from the operating position to the mounting position takes place by gravity.

The lock preferably comprises an excludable latch. The tax trap is preferably located between the latch and the main latch. In particular, it is provided that the tax trap is not integrated into the main case head, but protrudes separately through a separate opening in the forend.

different details of the lock according to the invention according to the embodiment in perspective views.

The following is a lock 1 in detail based on Fig. 1 to 6 explained. Fig. 1 and 2 show a section of the lock 1 with lock case 2 and the essential components in the lock case.

In the Fig. 3 to 6 are different components of the lock 1 hidden to explain the exact structure of the castle 1.

The lock 1 is a Sperrfallenschloss and formed with his lock case 2 and forend 3 as mortise lock.

The following is on the Fig. 1 to 6 Referenced.

The lock 1 comprises a main latch 4. The main latch 4 comprises a main latch head 5 and a main latch shaft 6. The main latch head 5 is arranged on the main latch shaft 6. The main trap 4 is movable over the main trailing shank 6 in a linear manner along the trapped trapping axis 30 with respect to the lock case 2. The main trap 4 is movable between an extended position (shown in the figures), a retracted position and an overstroke position. The skin trap 4 is rotatable in the overstroke position.

The lock case 2 has a recess 26. The main case 4 can be pushed into the lock case 2 so far that it is rotatable within the cuff 3 by 180 ° about the catch axis 30. This turning or turning of the main case 4 is carried out without opening the lock case 2. When turning the main case head 5 pivots through the recess 26th

The lock 1 further comprises a latch stop 27. In regular operation, the main latch 4 can be moved inwards until the Main case head 5 abuts the latch stop 27. The main case 4 is in the retracted position when the main case head 5 abuts against the latch stop 27. The latch stop 27 can be pivoted from an operating position to an assembly position to come out of engagement with the main case head 5. This makes it possible to press the main case 4 so far inside that the main case head 5 disengages from the forend 3 and is in the overstroke position. In the overstroke position, turning or turning of the main trap 4 is then possible.

The latch stop 27 is movable between the operating position and the mounting position, wherein in the operating position, the main case 4 is in the retracted position in operative connection with the latch stop 27, so that the latch stop 27 prevents movement of the main case 4 in the overstroke position. In the assembly position, the main trap 4 is in the retracted position out of operative connection with the latch stop 27, so that the latch stop 27 releases a movement of the main trap 4 in the overstroke position.

If the latch stop 27 is in the operating position, the movement of the main latch 4 from the extended position into the lock case 2 into the retracted position is limited by means of the latch stop 27. The movement of the latch stop 27 between the operating position and the mounting position can be done manually and / or by gravity. In particular, in the disassembled state of the lock 1, the lock case 2 can be moved in such a way that the fall stop 27 is moved from the operating position to the assembly position. For example, the lock can be turned upside down so that the movement of the body is caused by gravity Fallen stop 27 from the operating position to the mounting position.

The lock 1 further comprises a control catch arrangement 10. The control catch arrangement 10 comprises a control latch 11, which is arranged on a control case carrier 14. The exact configuration and arrangement of the tax trap 11 on the control case carrier 14 is in particular on the basis of 4 to 6 to see. Accordingly, the control latch 11 comprises a control case head 12 and a control latch shaft 13. The control latch shaft 13 is inserted in the control case carrier 14.

Furthermore, a control latch spring 15 is provided. The control latch spring 15 is inserted as a spiral spring on the control catch shaft 13. One end of the control latch spring 15 is supported against the control case carrier 14. The other end of the control latch spring 15 rests against a control latch stop 16 located on the control latch shaft 13.

The control case carrier 14 can be moved against the force of the control latch spring 15 relative to the control latch 11.

As based on the Fig. 1 to 6 it can be seen, the control case carrier 14 in the lock case 2 is arranged to be linearly movable parallel to the catch axis 30.

The control case carrier 14 has a driver 17. The driver 17 extends to the height of the back of the main case head 5. The main case head 5 can move the control case carrier 14 via the driver 17.

Furthermore, the control case carrier 14 comprises a slide extension 18 and an actuating surface 19. The slide extension 18 and the actuating surface 19 cooperate with a blocking element 20.

The lock 1 further comprises the blocking element 20. The blocking element 20 is received in the lock case 2 such that it can rotate about a blocking element rotation axis 21. The locking element rotation axis 21 extends perpendicular to the catch axis 30.

The blocking element 20 has a blocking surface 22. In its locked position, shown in Fig. 2 , the blocking surface 22 blocks a movement of the main case 4 inwards, in particular from the extended position into the retracted position. In the release position of the locking element 20, the blocking surface 22 allows the movement of the main catch 4, in particular in the retracted position and / or in the overstroke position. Via a blocking element spring 23, the blocking element 20 is moved into its blocking position.

The lock 1 comprises a nut 7, which can be rotated for example via a door handle. The nut 7 comprises several nut arms. As relevant here, a first nut arm 8 and a second nut arm 9 are described. The first Nussarm 8 pulls the main trap 4 back, in particular from the extended position to the retracted position. The second nut arm 9 actuates the blocking element 20. In particular, the second nut arm 9 moves the blocking element 20 from the blocking position to the release position.

On locking element 20 is a particular concave guide surface 24 is formed. The slide extension 18 of the control case carrier 14 slides on this guide surface 24. In a linear movement of the Steuerfallenträgers 14 can thus move the slide extension 18 via the guide surface 24, the blocking element 20 in the release position.

Fig. 1 shows the control case carrier 14 in an extended position of the control case carrier 14. In this case, the tax trap 11 is extended in a protruding position and is about the forend 3 over.

Fig. 2 shows the control case carrier 14 in a retracted position of the control case carrier 14, wherein the control latch 11 is in a retracted position.

The control case carrier 14 can be moved from its extended position parallel to the catch axis 30 over the retraction position away to an overstroke position. In this overstroke position, the actuating surface 19 of the control case carrier 14 strikes a complementary actuating surface 19 of the blocking element 20. This actuating surface 19 on the blocking element 20 is formed in particular on a projection 25 of the blocking element 20.

During its movement into the overstroke position, the control case carrier 14 thus holds the blocking element 20 in its release position via the two adjoining actuating surfaces 19.

The main case head 5 has a rear side, which points into the interior of the lock case 2.

In a normal operation of the lock 1, the latch stop 27 is in the operating position. Thus, the main trap 4 can be moved between the extended position and the retracted position, but not in the overstroke position.

In a normal operation of the lock 1 and with the door open, the main latch 4 is in the extended position and the control latch 11 is in the protruding position as in FIG FIG. 1 shown. The main trap 4 is urged by a main latch spring in the extended position. The main fall feather is in FIG. 1 pictured above right. The control catch assembly 10 is urged by a control catch assembly spring such that the control catch 11 is in the protruding position and the control case support 14 is in the extended position. Here, the Steuerfallenanordnungsfeder act on the tax trap 11 and / or the control case carrier 14.

The tax trap arrangement spring is in FIG. 1 visible through a slot of the control case carrier 14. The slot is used to guide the control case carrier 14 on the lock case. 2

Due to the fact that the control catch 11 and the control case carrier 14 are connected to each other via the control latch spring 15, the control latch 14 is also moved during a movement of the control latch 11 and the control latch 11 is moved during a movement of the control latch carrier, if there is no obstacle. A movement of the control catch 11 between the protruding position and the retracted position and / or a movement of the control case carrier 14 between the extended position and the retracted position is formed obstacle-free. Therefore, the control case wearer 14 assumes the retracted position when the control catch 11 is in the retracted position. The control case wearer assumes the extended position when the control catch 11 is in the protruding position.

In the in FIG. 1 illustrated extended position of the control case carrier 14 pushes the control case carrier 14, the blocking element 20 against the force of the locking element spring 23 in the release position. Thus, it is possible to move the main latch 4 from the extended position to the retracted position with the door open.

If the door is closed, the main case head 5 and the control case head 12 strike a strike plate of the door. The main trap 4 thereby moves from the extended position to the retracted position. The control catch 11 thereby moves from the protruding position to the retracted position. By the movement of the control latch 11 and / or by a system of the main latch 4 on the driver 17 of the control case carrier 14 is moved from the extended position to the retracted position. During the closing movement, a surface of the main case head 5 facing the blocking element 20 strikes the blocking element 20 and holds the blocking element 20 in the release position.

The movement of the main latch 4 and the locking latch 11 are matched to one another such that initially the locking element 20 facing surface of the main case head 5 strikes the locking element 20 and holds the locking element 20 in the release position before the control case support 14 occupies the retracted position. This prevents that during a movement of the control case carrier 14 from the extended position to the retracted position, the blocking element 20 enters the blocking position and prevents further movement of the main trap 4 in the retracted position.

The blocking element 20 in the release position, the control case carrier 14 in the extended position and the main case head 5 in the extended position are arranged to each other such that upon movement of the Main case head 5 in the retracted position first the blocking element 20 facing surface of the main case head 5 strikes the locking element 20 and holds the locking element 20 in the release position before the main case 4 via the driver 17 can move the control case carrier 14 in the retracted position. In particular, the main trap 4 initially strikes the blocking element 20 before the main trap 4 interacts with the control case carrier 14. For this purpose, in particular, the blocking element 20 is located between the main case head 5 and the driver 17, as in FIG. 1 shown.

Are during the closing movement of the door, the main trap 4 in the retracted position, the control latch 11 in the retracted position and the control case carrier enters the retracted position, so holds the main case 4, the blocking element 20 in the release position. The slide extension 18 is objected to by the guide surface 24. As a result, an interaction between the control case carrier 14 and the blocking element 20 is released.

FIG. 2 represents the state with the door closed. The main case 4 is retracted into an opening of the striking plate, while the control latch 11 rests against the strike plate. The main trap 4 is in the extended position. The main trap 4 therefore does not hold the blocking element 20 further in the release position. The control latch 11 is in the retracted position. The control case carrier 14 is in the retracted position. In the retracted position, the control case carrier 14 releases a movement of the blocking element 20 into the blocking position. The release is made possible in particular by the shape of the guide surface 24. The guide surface 24 only comes into contact with the slide extension 18 when the blocking element 20 is in the blocking position. The blocking element 20 is located in FIG. 2 in the locked position and prevents movement of the main case 4 from the extended position to the retracted position.

To open the door, the nut is actuated. As a result, the locking position of the locking element 20 is released by means of the nut arms 8, 9 and then moves the main latch 4 from the extended position to the Enfahrstellung, so that the door can be opened.

The blocking element 20 in the blocking position and the main trap 4 in the extended position are arranged to one another such that the main trap 4 allows movement of the blocking element 20 from the blocking position to the release position. The blocking surface 22 of the blocking element 20 is non-contact, in particular spaced, formed to the main case head 5 in the locked position. By a distance between locking surface 22 and main case head 5, a rotation of the locking element 20 in the release position at opening operation is possible. The distance between the blocking surface 21 and the back of the main case head 5 is preferably between 2 mm and 3 mm.

In addition to the normal operation, it is possible to rotate the main trap 4 and / or the control latch 1 with the lock case 2 closed. As a result, the lock 1 can be converted from a suitability for a left stop to a suitability for a right stop. Upon rotation of the main catch 4 about the catch axis 30, a blocking surface and an inclined surface of the main catch 4 are reversed in their position. Accordingly, upon rotation of the control latch 11, a blocking surface and an inclined surface of the control latch 11 are reversed in position.

If the control case carrier 14 is moved starting from its extended position and the thus extended control latch 11, it first passes through the Retracted. In a further movement of the control case carrier 14 in the same direction of movement of the control case carrier 14 assumes its overstroke position. When taking the overstroke position, the control case carrier 14 holds the blocking element 20 in the release position. In this release position, the main case 4 can be rotated by 180 °.

The control case carrier 14 is arranged and designed such that it can be moved into the overstroke position by a movement of the main catch 4 into the overstroke position. This is only possible if the control case carrier 14 is initially in the extended position and the blocking element 20 is thus in the release position.

The driver 17 is arranged such that the driver occurs in a movement of the main case 4 from the extended position into the retracted position in operative connection with the main trap 4 and / or is located. At the back of the main case head 5, a holding means 28 is provided, which always remains in contact with the driver 17, while the main case 4 is rotated in the overstroke position. The holding means 28 is an annular sliding surface for the driver 17th

In the following, the process of how the main trap 4 can be rotated in the case of the lock according to the invention will be described.

The initial state of the lock 1 corresponds to that in FIG. 1 illustrated state. Here is the description to FIG. 1 Referenced.

First, the latch stop 27 is moved from the operating position to the mounting position. Thereafter, the main trap 4 of the Extended position moved over the retracted position in the overstroke. During movement, the locking element 20 facing surface of the main case head 5 first strikes the locking element 20 and holds the locking element 20 in the release position. Thereafter, the main trap 4 hits the driver 17, in particular with the holding means 28. During the further movement of the main trap 4, the control case carrier 14 is moved by the movement of the main trap 4 from the extended position to the overstroke position.

The control catch 11 is moved by the movement of the control case carrier 14 from the extended position to the retracted position from the protruding position to the retracted position due to the control-falling spring 15. During the further movement of the control case carrier 14 from the retracted position to the overstroke position, the control latch 11 remains in the retracted position. In this case, a further movement of the tax trap 11 is prevented by a stop in the lock case 2. By the movement of the control case carrier 14 from the retraction position to the overstroke position, the control catch spring 15 is tensioned.

During the movement of the control case carrier 14 from the extended position to the retracted position, the control case carrier 14 is out of operative connection with the blocking element 20. In the retracted position, the slide extension 18 and the guide surface 24 are mutually objected. The locking element 20 is held by the main latch 4 in the release position. In the overstroke position, the control case carrier 14 holds the blocking element 20 in the release position. For this purpose, the actuating surfaces 19 abut each other.

The main trap 4 is now rotated in the overstroke position about the catch axis 30. Here comes the the blocking element 20 facing surface It is therefore necessary that in the overstroke position of the control case carrier 14 during the rotation of the main case 4, the control case carrier 14 holds the locking element 20 in the release position of the main case head 5, which has previously held the blocking element 20 in the release position , During the rotation of the main catch 4, the holding means 28 remains in operative connection with the catch 17. As a result, during the rotation of the main catch 4 the control catch carrier 14 is held in the overstroke position. Thus, at the same time the locking element 20 is held in the release position. In the release position, the blocking element 20 allows the rotation of the main trap 4.

After the rotation has taken place, the state can be determined by the main drop spring, the control catch arrangement spring and the control drop spring 15 and by a movement of the drop stop to the operating position FIG. 1 be restored. Here, however, the inclined surface and the blocking surface of the main trap 4 are reversed.

The control catch 11 can be pulled out of the lock case 2 and / or the forend 3 against the force of the control latch spring 15 and rotated. Thereafter, the control latch 11 moves back by the force of the control latch spring 15. The control case carrier 14 remains during the rotation of the control latch 11 in the lock case 2. The control case carrier 14 remains during the rotation of the control latch 11 in operative connection with the control latch 11, wherein the control latch spring 15 is tensioned.
