Description

The invention relates to a locking system for locking a locking element, in particular a door, with a base body that rotatably accommodates an actuating element for arrangement on one side of the locking element and a locking module for arrangement on the opposite side of the locking element, the actuating element having an interface for connection to the locking module having. Furthermore, the invention relates to a locking element with a locking system and a method for installing a locking system.

Such locking systems are already known and are used in very different areas of technology, for example to lock doors, flaps, hatches, windows or similar closing elements. The corresponding locking systems essentially consist of a base body, an actuating element and one or more locking modules. For the state of the art, refer to the publications DE 10 2018 102286 A1 and DE 20 2014 101593 U1 referred.

The base body is usually arranged on the outside of the closing element and is used for the rotatable reception or mounting of the actuating element. The actuating element extends from the outside of the closing element through the closing element to the inside of the closing element and is connected there to the locking module. The operating element can usually be rotated by hand from the outside of the door and by the connection of the operating element to the locking module this can then be switched between a locking position in which the locking element cannot be opened and is fixed relative to the frame of the locking element, and a Unlocked position in which the closing element can be opened and is not fixed relative to the frame, are moved back and forth.

In order to connect the actuating element and the locking module, the actuating element usually has an interface which can be rotated together with the actuating element and which enables a detachable connection between the actuating element and the locking module. Various locking modules can thus be arranged on the actuating element via the interface. For example, the locking modules can be cams of different sizes and/or with different degrees of compression, which can be connected to the actuating element via the interface depending on the requirements.

Although such a locking system is characterized by a certain variability due to the possibility of using different locking modules, it is limited to locking modules that only require a connection to the actuating element. In this respect, the complexity of the locking modules is limited.

Proceeding from this, the invention sets itself the task of specifying a closure system which is characterized by increased variability.

The object is achieved with a locking system of the type mentioned in that the base body has a fixed interface for connection to the locking module, depending on the type of locking module this can be connected either only to the rotating interface or to both interfaces.

The additional fixed interface on the base body creates another connection point for the locking module, so that locking modules that also require a fixed interface in addition to the rotatable interface can be used. In this respect, the range of locking modules that can be used is expanded to include locking modules of different types and the variability of the locking system is increased overall.

With regard to the locking module, it is proposed that a first locking module type and a second locking module type be provided, the first locking module type being a cam module and the second locking module type being a latch lock module. The cam module can only require a rotatable interface and therefore only a connection to the actuating element, whereas the latch lock module also requires a fixed one in addition to the rotatable interface interface required. The various types differ in that they are connected to the actuating element and/or to the base body. Interlocking modules that can be connected via the same interface or the same interfaces are therefore interlocking modules of the same type.

In a further development of the modules, it has proven to be advantageous if the cam module can only be connected to the rotating interface and the latch lock module can be connected both to the rotating and to the fixed interface. The latch lock module can have a more complex structure than the cam module insofar as the latch lock module can also be connected to the base body in addition to the actuating element and in this respect can have not only rotatable components but also fixed components.

Furthermore, it is proposed that the fixed interface is used or remains unused depending on the type of locking module. If the locking module only requires the rotating interface, the fixed interface can remain unused and thus free. When converting or changing the locking module, in particular from a cam module to a latch lock module, the fixed interface can then also be used for the connection.

With regard to the design of the interfaces, it has proven to be advantageous if they enable a detachable connection. The locking module can thus be releasably connectable to the actuating element via the rotating interface and to the base body via the fixed interface. The detachable connection enables simple assembly and also simple disassembly and thus simple changing of the locking module. The locking modules can be connected to the interfaces via connecting elements, in particular screws. The connecting elements can have threads so that they can be screwed into the interfaces.

It has also proven to be advantageous if the interfaces are designed as mechanical interfaces. Mechanical interfaces allow force to be transmitted between the locking module and the actuating element or between the locking module and the base body and in this respect allow the elements to be firmly connected.

With regard to the fixed interface, it is proposed that this has several, in particular four, connection points. The multiple connection points allow reliable attachment of the locking module to the base body, since the forces to be transmitted can be divided between multiple connection points. It is possible that all available connection points of the interface are used for the connection, but it is also possible that fewer connection points are used and some connection points remain unused. Whether all or only some connection points are used can depend on the design of the respective locking module. The connection points can be opposite one another with regard to the actuating element or the actuating axis. With four connection points, these could be in pairs opposite each other.

Furthermore, with regard to the design of the fixed interface, it has proven to be advantageous if the connection points of the base body are designed as domes, in particular as screw-in domes. This enables a simple connection to the respective locking module and a firm hold of the connecting elements. The connecting elements can be screwed into the dome. The domes can have an internal thread. Alternatively, the connecting elements can also be designed as self-tapping screws.

With regard to the design of the locking module, it has proven to be advantageous if the cam module has a locking element designed as a cam tongue. The cam can also be designed as a roller tongue or as a hooked tongue. A roller tongue reduces the force required when closing the closing element and also allows a certain contact pressure of the closing element. A hooked tongue can enable reliable locking and to this extent can hook into correspondingly designed elements on the closing element frame.

Furthermore, it has turned out to be advantageous with regard to the cam latch if the latter is adjustable in height. By adjusting the height, the locking element or the cam can be moved in a direction parallel to the actuating axis, which allows an adaptation to the geometry of the locking element and/or the locking element frame. Furthermore, the contact pressure of the locking element can also be adjusted by the corresponding height adjustment. In terms of construction, the locking module can have a guide in which the latch tongue can be movably mounted. The locking element can, for example, be releasably connected to the guide using a screw and can therefore be adjusted in height very easily.

Furthermore, it has proven to be advantageous if the cam latch is rotatably coupled to the actuating element. The cam can thus be moved back and forth between a locking position and an unlocking position by rotating the actuating element. The cam can thus directly with the actuator be coupled. During the movement of the actuating element about the actuating axis, the latch tongue can also rotate about the actuating axis. If the actuating element is rotated by 90 degrees, for example, the cam can also be rotated by 90 degrees accordingly. In practice, a 90 degree rotation is often sufficient to achieve reliable locking and unlocking.

According to a further advantageous embodiment, it is provided that the cam latch is connected to the actuating element via a rod drive. The rod drive can have a number of rods, so that a single actuating element actuates a number of cam tongues, that is to say can be rotated back and forth between the locked and the unlocked position. In this respect, the locking system can also enable multi-point locking. The rod drive can have a coupling element, in particular a plate-shaped one, which can be connected or rotatably coupled to the actuating element via the interface. With a rotary movement of the actuating element, the coupling element can then move accordingly and also be rotated about the actuating axis. The rods of the rod drive can be arranged on or connected to the coupling element. The connection points of the rods on the coupling element can be opposite one another with regard to the connection point on the actuating element. The rotary movement of the actuating element or of the coupling element thus leads to a substantially linear movement of the rods, which can then in turn be used to actuate sash latches coupled to the rods.

With regard to the latch lock module, it is proposed that this has a frame connected to the stationary interface and a locking element that is movably arranged relative to the frame. In this respect, the latch lock module can be more complex than the cam module be configured and due to the frame also require a fixed interface in addition to the rotatable one. The locking element can be connected to the rotatable interface or to the actuating element and can be moved back and forth between a locking position and an unlocking position. The frame can be designed to be stationary relative to the locking element and act as a bearing for the locking element.

In a further development of the frame, it is proposed that this has two frame plates, between which the locking element is accommodated in a pivoting manner. The two frame plates can each have two frame legs, which can be arranged at an angle of 90 degrees to one another. One of the frame legs can be designed as a fastening leg and provided for connection to the stationary interface. The other frame leg can be designed as a bearing leg for mounting the locking element. The two bearing legs of the frame plates can lie on top of each other, so that they can be connected to the connection points of the fixed interface via connection elements, in particular screws. For this purpose, the connecting elements can extend through both frame plates or through both bearing legs. In this respect, the frame plates can be positively connected to the base body. The bearing legs of the two frame plates or the bearing legs can have a distance from one another which can essentially correspond to the thickness of the locking element. The locking element can thus be pivotally accommodated between the two bearing legs.

With regard to the design of the locking element, it has proven to be advantageous if this is designed as a rotary latch. A rotary latch enables a bolt to be reliably secured in the frame, so that the closing element is reliably in the locked position can be held. The rotary latch has a mouth-shaped or U-shaped receiving contour in which a bolt can be received. The bolt can be designed in the form of a bolt. To this end, it is also proposed that the locking element, in a locking position, engages around the bolt in a form-fitting manner, at least in sections. The bolt can be arranged on the locking element frame and thus be designed to be stationary, so that when the bolt is accommodated in the locking element or in the rotary latch, the locking element is fixed relative to the locking element frame. In contrast to the cam module, the locking element of the latch lock module alone cannot lock the locking element, but a corresponding bolt on the locking element frame is required. In terms of construction, the frame can have a locking groove into which the bolt can be inserted and in which the bolt can be held in a form-fitting manner by the locking element. The locking groove can extend parallel to the actuation axis through both frame plates and have a U-shaped contour.

Furthermore, it has turned out to be advantageous with regard to the locking element if this is pretensioned in the unlocked position. A spring element, for example, which can be supported on the frame, can be provided for prestressing the locking element. The spring element can be designed as a torsion spring or as a spiral spring. When the closing element is closed, the bolt can be moved into the locking element and also into the locking groove of the frame and the locking element can be rotated into the locking position against the force of the spring element. The locking element can be rotatable perpendicular to the direction of actuation of the actuation element.

Furthermore, it has proven to be advantageous if the locking element is secured in the locking position via a locking pin. The locking element can be secured in the locking position via the locking pin in such a way that it cannot move back into the unlocked position and also cannot independently release the bolt again. The locking bolt can lead to a kind of self-locking if the locking element has been moved into the locking position by the bolt. When the locking element has reached the locking position, the locking bolt can independently secure the locking element. In this respect, the locking pin can also be prestressed accordingly. In the locked position, reverse rotation may not be possible due to spring tension.

Furthermore, with regard to the latch lock module, it is proposed that this has a driver coupled to the actuating element for unlocking the locking element. The driver can be connected to the actuating element via the co-rotating interface and can thus be rotated about the actuating axis together with the actuating element. When the actuating element rotates, the driver can come into contact with the locking bolt, move it and thus lead to unlocking of the locking element. Because if the locking bolt no longer secures the locking element, it snaps open due to the spring tension and the bolt is released. In contrast to the cam module, the actuating element in the case of the latch lock module can only be coupled indirectly to the locking element. The driver can extend perpendicularly to the actuation axis. The driver can also be connected to the actuating element via a coupling sleeve, so that the driver itself does not have to be arranged at the end of the actuating shaft. The coupling sleeve can be designed in the shape of a cylinder or pot and placed on the actuating element. The driver can be arranged in the jacket area of the coupling sleeve.

It is also proposed that the actuating element be freely rotatable together with the driver in a first angular range and be movable in a second angular range via the driver of the locking pin. The actuating element can be rotated freely until the driver comes into contact with the locking pin and further rotary movement of the actuating element then causes the locking pin to be moved. With a movement in the second angular range, the driver can take the locking pin with it in order to unlock the locking element.

A further aspect of the invention provides that the actuating element has an actuating shaft that extends through the base body, with the interface being arranged at the end of the actuating shaft. The corresponding locking module or the locking element or the driver can be screwed onto the actuating shaft via the interface arranged at the end of the actuating shaft. The interface can be designed as a screw-in opening with a thread, so that the respective module can be screwed to the actuating shaft via the interface. The actuating shaft can extend through the base body and in this respect can reach from the outside of the closing element to the inside of the closing element. The locking module arranged on the inside of the base body can thus be moved or actuated from the outside.

In a further development of the actuating element, it is proposed that it have a grip area which is movably connected to the actuating shaft. The actuating shaft can be turned by hand via the handle area. The handle area can have a T-shape, which enables good handling. The handle portion may be located at the opposite end of the actuation shaft interface and the handle area can be connected to the actuating shaft in the manner of a hinge. The handle area can thus be pivoted in relation to the actuation shaft, in particular about a pivot axis arranged perpendicular to the actuation axis.

In this context, it has proven to be advantageous if the handle area can be pivoted out of the base body and pivoted into the base body. The actuating element can be rotatable in the pivoted-out position and non-rotatable in the pivoted-in position. The base body can be designed in the manner of a trough, which encompasses the handle area in the pivoted-in position. The base body can thus encompass the handle area at least laterally in the pivoted-in position. The base body can also have a recessed grip that makes it easier to pivot the grip area out of the base body. This is because the handle area can partially protrude in relation to the recessed grip, so that it is possible to reach into the recessed grip and thus behind the handle area and swing it out of the base body.

Furthermore, provision can be made for the handle area to be pretensioned in the pivoted-out position. This makes it easier to handle, since it is not first necessary to pivot the handle area out of the base body for actuation. If necessary, the recessed grip in the base body can also be dispensed with due to the prestressing of the grip area.

In a further development of the invention, it is proposed that the handle area be secured in the pivoted-in position via a safety device in such a way that it cannot be transferred to the pivoted-out position. The safety device can be arranged in the grip area and can engage in the base body in such a way that the grip area cannot protrude from it can be swung out. The security device can have a lock cylinder, which can be actuated by a key or by a tool. In this respect, it may be necessary to first unlock the safety device with a key or a tool before the handle area can then be pivoted out of the base body and the locking module can then be actuated to unlock the locking element. According to an advantageous development, it is also possible for the lock cylinder to be covered with a cap in order to prevent dirt from entering the lock cylinder. Before the safety device can be unlocked, this cap must first be removed.

Furthermore, it has proven to be advantageous if a catch hook is provided for holding the handle area in the pivoted-in position. The catch hook can be part of the base body and can be moved against the force of a spring. If the grip area is pivoted into the base body, the grip area can move the catch hook against the spring force. When the grip area has reached its swiveled-in position, the catch hook can move back due to the spring force, hook into or behind the grip area and thus hold it in place. Furthermore, it is also possible for the catch hook to be moved by the safety device against the spring force when pivoted in. The handle area can thus also be swiveled in when the safety device is secured or locked. In this respect, the catch hook can enable a push-to-lock function, so that the grip area simply has to be pressed shut and is then automatically secured. The catch hook can be mounted from the outside of the base body, so that the inside or the back of the base body does not have to have any corresponding assembly openings. This is advantageous with regard to the tightness of the base body in relation to the closing element. In particular In the area into which the handle area can be pivoted, the base body can thus have a closed rear side.

A further advantageous development provides that the base body has an indicator surface which is visible when the handle area is swiveled out and is not visible when the handle area is swiveled in. The indicator surface can also be used to identify from a distance whether the handle area is pivoted into the base body and therefore cannot be rotated, or whether the handle area is pivoted out of the base body. Since a rotary movement of the actuating element is not possible in the pivoted-in state, the indicator surface can be used to recognize at first glance whether the actuating element can be actuated or not. Since the safety device secures the handle area in the pivoted-in position, it can also be determined to what extent unauthorized actuation of the actuating element is possible. The indicator surface can have a signal color that differs from the color of the handle area and the base body. In practice, it has turned out to be advantageous if the signal area is red.

Furthermore, the handle area can be prestressed into the swung-out position, in particular by means of a spring. If the safety device is unlocked to this extent, the grip area can spring open automatically due to the spring force, so that the indicator surface is then also visible immediately after unlocking. If the handle area is folded or swiveled in again, it is moved against the force of the spring, so that the spring is tensioned by this movement.

With regard to the locking system, it is also proposed that this has several locking modules of different types, which can be used selectively. Such a set, consisting of a base body, an actuating element and several locking modules, which can be connected via the interface to the actuating element and, depending on the type of locking module, also to the base body, offers a wide range of applications and, depending on the requirement, a locking module can be selected from a group of several locking modules. It is advantageous if the group of locking modules contains locking modules of different types. Different locking modules of one type can also be provided, for example a cam module with a hook tongue and a cam module with a roller tongue.

With regard to the object mentioned above, a closing element, in particular a door, with a locking element is also proposed, the locking element being designed in the manner described above. In this respect, the advantages already described with regard to the locking system also result.

Furthermore, with regard to the object mentioned at the outset, a method for installing a locking system for locking a locking element, in particular a door, is proposed, the locking system having a base body that rotatably accommodates an actuating element for arrangement on one side of the locking element and a locking module for arrangement on the opposite side side of the closing element, wherein the actuating element has an interface for connection to the locking module, wherein the base body has a fixed interface for connection to the locking module and depending on the type of locking module, this is optionally connected only to the rotating interface or to both interfaces . The advantages already described with regard to the locking system result.

Furthermore, a method for locking a closing element, in particular a door, is also proposed in this respect, the method being carried out with a locking system which is designed in the manner described above.

In the representation of 1 a base body 3 with an actuating element 5 is shown in a plan view. The base body 3 is arranged on the outside of a closing element designed as a door, which is not shown in the figures. About the locking system 10, the door can be fixed in the closed position relative to the door frame, so that the door can no longer be opened. This is subsequently based on the Figures 4a to 4c explained in more detail.

In order to unlock the door or the locking system 10, the operating element 5 must be rotated about an operating axis B. In the in the 2 and 3a to 3d However, in the positions of the actuating element 5 shown, it is located in the base body 3 in such a way that a rotary movement of the actuating element 5 is not possible. In order to rotate the actuating element 5, it must first be pivoted out of the base body 3, as is shown in FIGS Figures 4a to 4c can be seen. The actuating element 3 essentially consists of two parts, namely the one in the Figures 1 to 4 to be recognized handle area 5.2 and an actuating shaft 5.1, which extends through the base body 3 therethrough. The actuating shaft 5.1 is rotatably mounted in the base body and is connected at one end to the handle area 5.2 via a hinge connection. Due to the pivotable connection between the handle area 5.2 and the actuating shaft 5.1, the handle area 5.2 can be pivoted relative to the actuating shaft 5.1 and thus also relative to the base body 3, as is shown in FIGS Figures 4a to 4c is evident.

So that the handle area 5.2 can be pivoted out of the base body 3, the base body 3 has a recessed grip 3.2. The gripping area 5.2 protrudes slightly over the gripping recess 3.2, so that one hand can reach into the gripping recess 3.2 and behind the gripping area 5.2 in order to swing the gripping area 5.2 out of the base body. In the in the Figure 4b shown pivoted position, the actuator 5 can then be rotated, since the base body 3 no longer encompasses the grip area 5.2 and insofar as this no longer prevents a corresponding movement. Since it is necessary to pivot the actuating element 5 out of the base body 3 in order to rotate it, preventing this pivoting out can also prevent the door from being able to be correspondingly unlocked. In order to secure the handle area 5.2 in the base body 3, a securing device 7 in the manner of a lock is provided. Before the actuating element 5 can therefore be swiveled out and rotated, the safety device 7 must first be unlocked.

Like this in the Figures 3a to 3d can be seen, the security device can include 7 different types of locks. For example, in the Figures 3b and 3c various plug-in cylinders shown, which can be unlocked with a key and in the Figure 3a a safety device 7 is shown, which can be unlocked using a tool. In addition, a protective cap can also be provided, like this one in FIG 3d can be seen and with which it can be prevented that dirt penetrates into the lock cylinder of the safety devices 7.

Furthermore, the locking system 10 enables a push-to-lock function. For this purpose, the base body 3 has a spring-loaded catch hook 3.3, which engages in the handle area 5.2 in the swiveled-in position of the handle area. The catch hook 3.3 automatically deflects against the spring force when the grip area 5.2 pivots inwards and then automatically engages the grip area 5.2 or the safety device 7 again due to the spring force. A renewed pivoting of the handle area 5.2 is then only possible if the safety device 7 is unlocked. Since the catch hook 3.3 automatically gives way when the grip area 5.2 is pivoted in, the grip area 5.2 can always be pivoted into the base body 3 are, regardless of the position of the safety device 7, and is then initially locked.

The catch hook 3.3 is mounted in the base body 3 from the front or outside thereof, so that the base body 3 does not require any corresponding assembly openings. This is, for example, based on the Figures 5a to 5c to recognize. This is because the rear or inner side of the base body 3 has no breakthroughs or openings, at least in the area in which the pivoted handle area 5.2 is arranged, but rather a closed rear side, so that no seals are required in this respect either.

How this continues in the Figures 4a to 4b As can be seen, the base body 3 has an indicator surface 3.1, which only becomes visible when the handle area 5.2 is pivoted out of the base body 3. This indicator surface 3.1 is colored in a signal color and is therefore easy to see even from afar. In this respect, it can then be seen at first glance whether the handle area 5.2 is swung out or not and whether the door is reliably locked.

In order to lock a door via the locking system 10, a locking module 1 with a locking element 2 is provided on the back of the base body 3, which can be rotated back and forth via the actuating element 5 between a locking position and an unlocking position. In the Figure 4a the locking position is shown. In this, the locking element 2 of the locking module can engage in or behind the door frame and thereby fix the door relative to the door frame. To open the door, then the locking element 2 must first in the Figure 4c unlocking position shown are transferred. For a corresponding actuation, the locking module 1 is coupled to the actuating element 5, so that the locking module 1 can be transferred to the locked position or to the unlocked position.

Like this in the Figure 4c can be seen, the locking element 2 is rotated in this unlocked position by about 90 degrees relative to the locked position, so that the locking element 2 no longer engages in or behind the door frame in this position and the door can then be opened to that extent. To connect the locking module 1 to the actuating element 5, an interface 6 is arranged at the lower end of the actuating shaft 5.1, which interface rotates together with the actuating element 5 when it is actuated. The locking module 1 can be connected to the actuating element 5 in a rotationally fixed manner via this interface 6, so that the locking element also rotates about the actuating axis B when it is actuated. For the connection, a connecting element 8 in the form of a screw can be used, via which the locking module 1 can then be releasably connected to the actuating element 5, as is also the case, for example, in FIG Figure 5a , showing the underside of the locking system 10 can be seen.

In addition to the interface 6 that can be rotated together with the actuating element 5 , another interface 4 is also provided, which is used to connect the locking module 1 to the base body 3 . In contrast to the interface 6, however, the interface 4 is designed to be fixed. At the in the Figures 5a to 5d Locking module 1 shown, however, this interface 4 is not occupied, since this type of locking module only requires a connection to the actuating element 5. Other locking module types, such as the one in the 6 shown latch lock module 1.2, but not only need a connection to the actuating element 5, but also a non-rotatable fixed interface for connection to the base body 3. The locking system 10 can thus be used for both locking modules 1 which only require interface 6, as well as for those which require interface 4 in addition to interface 6. In the following, based on the Figures 5a to d now first differently configured locking modules 1 will be described, which can be assigned to the first type of locking module and all of which are designed in the manner of a cam module 1.1, before then following on in the 6 and 7a, 7b illustrated second locking module type is discussed in more detail.

The cam module 1.1 according to the Figure 5a has a locking element 2 designed as a roller tongue, which is connected directly to the interface 6 or to the actuating element 5 . When the actuating element 5 is rotated, the locking element 2 also rotates back and forth accordingly, as was the case above with regard to FIG Figures 4a to 4c has already been described. The roller tongue can rotate freely around its longitudinal axis, which makes it easier to pull the door shut, since the roller can roll on or on the door frame. In addition, a certain compression of the door seal can also be achieved via the roller tongue.

When designing in the Figure 5b is shown, the roller tongue is connected to the actuating element 5 via a guide 1.11. The roller tongue can thus be moved in the direction of the actuation axis and thus perpendicular to the door, as a result of which the roller tongue can be adapted to different geometrical dimensions of the door or the door frame. The locking module Figure 5c also has the in the Figure 5b shown leadership. In this locking module 1, however, the locking element 2 is in the form of a hook tongue.

At the in the Figure 5d Locking module 1 shown is also a cam module 1.1, but the actual cam tongues are not shown. Rather, a rod drive 1.12 is shown, via which the actuating element 5 can also be equipped with several cams can be connected. For this purpose, the rod drive 1.12 has two rods 1.13, which extend in different directions and via each of which a cam latch can be driven. In this respect, this locking module 1 offers a multi-point locking for the door. The rod drive 1.12 also has a coupling element 1.14, which is connected to the actuating element 5 via the interface 6 and which ensures that the rotational movement of the actuating element 5 is converted into a substantially linear movement of the two rods 1.13.

In the 6 a locking module 1 of a different type is shown, namely a latch lock module 1.2. In contrast to the cam module 1.1, the latch lock module 1.2 not only requires a rotatable interface 6 for connection to the actuating element, but also a fixed interface 4 for connection to the base body 3. The corresponding interface 4 has a total of four individual connection points 4.1 are arranged in pairs on the underside of the base body 3 next to the actuating shaft 5.2. The latch lock module 1.2 is designed in two parts, unlike the cam module 1.1, and essentially consists of a frame 1.21 and a driver 1.25. The driver 1.25 basically works in a similar way to the locking element 2 of the cam module. This is because it is also connected to the rotatable interface 6 and can thus be rotated back and forth via the actuating element 5 . The driver 1.25 is arranged on a coupling sleeve, which is connected in the upper area to the actuating shaft 5.1 and at the lower end of the driver 1.25 perpendicular to the actuating axis B, as in the 6 can be seen.

The second part of the latch lock module 1.2 is designed as a frame 1.21 and is connected to the base body 3 via the fixed interface 4 . The frame 1.21 has two frame plates 1.22, each of which consists of two frame legs arranged at 90 degrees to one another, namely a fastening leg and a bearing leg. The fastening legs lie directly on top of each other and are connected to the four connection points 4.1 of the interfaces 4 by means of screws. The bearing legs, which are arranged perpendicularly to the fastening legs, are at a certain distance from one another, and between them a locking element 2 designed as a rotary latch is arranged in a rotatably movable manner. The rotary latch can, together with the two frame legs 1.22 or with the two bearing legs, receive a bolt 1.26 in a form-fitting manner, so that the bolt 1.26 can then at least no longer be moved translationally. In this position, the door can no longer be moved relative to the door frame.

To receive and secure the bolt, the rotary latch has a U-shaped receiving area and the bearing legs have a locking groove. When the door is closed, the bolt 1.26 dives into the locking groove and at the same time into the catch. The rotary latch is thereby pivoted and rotated into the locked position, as in the Figures 7a and 7b is evident. The locking element 2 is biased into the unlocking position by a spring element, so that when the door is closed, the bolt 1.26 is moved against the force of the spring and this pushes the locking element 2 into the locking position. In the locked position, the rotary latch is held by a locking pin 1.24 and prevented from rotating back into the unlocked position. The door is thus automatically locked when it is closed when the locking element has reached the locked position.

To open the door, the rotary latch must be rotated back to the unlocked position. Since the rotary latch is biased into the unlocked position this happens automatically when the locking pin 1.24 no longer fixes the rotary latch in the locking position. The rotary latch then springs back into the unlocked position and the door can be opened again.

In order to move the locking pin 1.24 accordingly, the actuating element 5 must be rotated about the actuating axis B, just as has already been described above with regard to the cam module 1.1. During this movement, the driver 1.25 comes into contact with the locking pin 1.24 and takes it with it accordingly. Due to the corresponding movement of the locking pin 1.24, the rotary latch is then released and snaps open due to the spring preload. A renewed movement of the rotary latch into the locking position is not possible through the driver 1.25 or through a rotation of the actuating element 5. Unlike the case with the cam module 1.1, with the latch lock module 1.2 the locking element 2 must be transferred into the locking position by the closing movement of the door or by the corresponding movement of the bolt 1.26. By rotating the actuating element 5, the locking element 2 can therefore only be unlocked but not locked.
