Description

Modular locking system

The invention relates to a modular locking system for a door with a trough which can be arranged on a first side of the door, an actuating lever which can be pivoted relative to the trough for actuating a locking device which can be arranged on the side of the door for locking the door, a safety device for locking the operating lever on the trough and an unlocking module to release the lock.

Such locking systems are used in very different areas and essentially serve to lock or unlock a door, a window, a flap or other locking elements. A door is used below to represent these different closing elements. In the case of such locking systems, a trough is generally arranged on the outside of the door which can at least partially close or cover at least one of the openings arranged in the door. An actuating lever is usually arranged on the trough, which is coupled to a locking device arranged on the inside of the door in such a way that the locking device can be moved back and forth between a locking position and an unlocking position via a movement of the actuating lever. In the unlocked position, the door can be moved and opened or closed. If the door is locked in the closed position, it can no longer be moved and can only be opened again when the locking device is moved back into the unlocked position.

To prevent undesired door unlocking, a safety device is usually provided with which the actuating lever can be locked on the trough. When the actuating lever is locked, it cannot be moved and therefore the locking device cannot be pivoted into the unlocked position for unlocking the door.

In order to unlock the locking device or the door and then to open it, it is necessary to first release the locking of the Actuate transmission lever. To solve this, a release is provided which interacts with the safety device and via which the locking of the actuating lever can be released. As soon as the lock is released, the actuating lever can thus be moved and thereby the locking device can be moved back and forth between the unlocking position and the locking position.

In the case of locking systems known from the prior art, it has also proven useful if the release is not firmly attached to the rest Components is connected, but when this is designed as an unlocking module and can be variably exchanged. A locking system with such an unlocking module is shown, for example, in DE 10 2017 108 446 A1. The unlocking module of this locking system is detachably connected to the trough and can be pulled down out of the trough or pushed into the trough from below.

DE 20 2007 004 434 U1 also shows a modular locking system in which an unlocking module is provided that can be inserted into the recess from the front.

In both of the locking systems described in the prior art, the trough forms a type of frame or receptacle for the unlocking module, so that these can be exchanged quite easily, but the unlocking modules must be adapted to the trough or to the module receptacle of the trough, so that the design of the release modules are limits.

The invention is based on the objective of specifying a modular locking system with improved variability.

In the case of a modular locking system of the type mentioned at the outset, this task is achieved in that the unlocking module is designed as a hollow extension.

The design of the release module as a trough extension enables the release module to be configured in a variable manner independently of the trough. This is because the release module no longer has to be inserted into the trough and therefore no longer has to be adapted to the trough, in particular with regard to its geometric dimensions. Furthermore, it also opens up the independence of the unlocking module from the trough the possibility that several unlocking modules can be used at the same time.

With regard to the design of the unlocking module, it has proven to be advantageous if it has a lock cylinder which releases the locking of the actuating lever in an unlocked position. The lock cylinder can, for example, be moved into the unlocked position by rotating it around an unlocking axis by means of a suitable key or a suitable tool. If the wrong key or the wrong tool is used, the locking cylinder cannot be moved and the locking of the operating lever cannot be released. The lock cylinder does not necessarily have to have a cylindrical shape, but can very generally be a locking means. The term lock cylinder is used below to represent a locking means.

With regard to the variability of the device, it has been found to be advantageous if several release modules are provided, which can optionally be used as a trough extension. The unlocking modules to be used can be selected from a large number of different unlocking modules depending on the requirements, and the various unlocking modules can differ with regard to their locking cylinders. To this end, it is possible, for example, that the various unlocking modules require different keys or different tools for rotating the lock cylinder. To solve the locking of the operating lever, a certain tool / lock cylinder combination or a key / lock cylinder combination can be provided. Furthermore, it is also possible for the unlocking modules to differ with regard to their size and their geometrical dimensions. Furthermore, it is advantageous if several of the unlocking modules can be used together, with the locking of the actuating lever being able to be released by each of the unlocking modules. It is therefore not always necessary to select only one unlocking module from the various unlocking modules, but several can also be selected and then used together. In this configuration, the lock can already be released by unlocking only a single unlocking module. The several securing blocks can extend the trough together and be attached to one another.

Furthermore, the release modules can be designed as end pieces or as inter mediate pieces. The intermediate pieces can be provided between the trough and an end piece or a further intermediate piece. If only one release module is provided, this can be designed as an end piece. If, in addition, additional security modules are used, these can be staltet as spacers and inserted between the trough and the end piece. The end piece can have a different contour than the intermediate piece in the end area, for example the end piece can be rounded at the lower end. In terms of their functionality, the end pieces and the intermediate pieces do not advantageously differ, but they can be equipped with different lock cylinders. It is also advantageous if several release modules with different locking cylinders are used. This enables the lock to be released by different keys and / or different tools. Often it is, for example, desirable that different people can unlock the door, but they do not have the same key or should have the same key. By using several unlocking modules with different Lock cylinders can therefore each person sit an individual key be that can only unlock one of the unlocking modules. In this respect, the door can then be unlocked with various keys. In practice, the use of two different unlocking modules has proven itself.

With regard to the position of the release module, it has been found to be advantageous if it is arranged below the trough.

The unlocking module can adjoin the trough at one end, in particular at an upper end, and thus extend the trough downward. The unlocking module can be inserted from the front, that is, from the direction of the first side of the door, into an opening in the door below the recess. The unlocking module can have the same width as the trough, so that the impression is given that the unlocking module itself is part of the trough. Furthermore, this embodiment can also reliably cover an opening in the door with a constant width. If several unlocking modules are used at the same time, they can be arranged in a row one below the other. In an alternative embodiment, however, it is also possible for the releasing module to extend the trough upwards and to be arranged correspondingly above the trough.

Furthermore, the unlocking module can also have a guide element, in particular designed as a guide bolt, via which the unlocking module can be guided in the trough. If the release module extends the trough downwards, the guide element can be arranged in the upper end region of the release module. Two guide elements designed as guide bolts have proven to be particularly advantageous, which run parallel to one another. The trough can have a receptacle for the guide elements into which the guide can intervene guiding elements. The unlocking module can be held on the trough via the guide elements.

Furthermore, it has been found to be advantageous if the release module has a support area to rest on the door. Due to the support area, the unlocking module can rest flat on the first side of the door and cover an opening in the door. The unlocking module can thus be stored directly on the door and it is not absolutely necessary that the recess is directly connected to the unlocking module. The support area can have three support surfaces, in particular two lateral and an upper or lower support surface, so that the unlocking module can rest on the door on three sides. The design of the support area can be dependent on the position of the unlocking module. If the unlocking module is designed, for example, as an intermediate piece, the support area can only comprise two lateral support surfaces. If the unlocking module is designed as an end piece, the support area can additionally comprise an upper or a lower support surface, depending on whether the unlocking modules extend the trough upwards or downwards. The support area can be designed in the manner of a collar.

With regard to the trough, it has proven to be advantageous if it has a receiving contour for receiving the actuating lever. The actuating lever can be in the locked position in the receiving contour and thus be positively connected to the trough. A rotary movement of the actuating lever is then not possible due to this form fit. To operate or unlock the door, the operating lever must first be pivoted out of the receiving contour of the recess. For this purpose, the actuating lever can be swiveled out of the trough about a swivel axis running in particular parallel to the door. From a certain angle it is then possible to use the operating lever to pivot about an actuating axis in relation to the trough, where in the actuating axis can be arranged perpendicular to the door and perpendicular to the pivot axis. This movement of the actuating lever around the actuating axis can then lock the door or the locking device or unlock it. In the pivoted-in position, the actuating lever can be taken up flush in the receiving contour, so that it does not protrude from the trough. The actuating lever can be biased into the swiveled-out position via a spring element, so that the actuating lever is automatically swiveled out of the receiving contour when the locking mechanism is released.

In this context, it has also turned out to be advantageous if the unlocking module also has a receiving contour that is aligned with the receiving contour of the trough. This enables the actuating lever to be positively received in the swiveled-in position in both of the receiving contours. The receiving contour of the trough can thus be lengthened by the receiving contour of the release module. The receiving contour of the unlocking module can be designed in the same way as the receiving contour of the trough in terms of its width and depth. If several unlocking modules are used, all unlocking modules can have a receiving contour that is aligned with one another.

With regard to the actuating lever, it has also been found to be advantageous if the actuating lever has an actuating portion and a lock cylinder cover articulated to the actuating portion. In the pivoted-in position of the actuating lever, the lock cylinder cover can cover the unlocking module (s) so that the lock cylinders are not visible. The lock cylinder can thus be protected against dirt or other external influences, for example. The lock cylinder cover can be placed in the structure of the release module or the release modules. The release module can, however, also be movable with respect to the actuating section when the actuating lever is locked. To unlock the door, the lock cylinder cover can first be pivoted relative to the actuating section and the lock cylinder is thereby exposed. In a next step, the lock cylinder can then be rotated around the unlocking axis by means of a key or tool and thus moved into the unlocked position, whereby the locking of the actuating lever is then released and it can be pivoted out of the receiving contour. The axis about which the lock cylinder cover can be pivoted relative to the actuating section can run parallel to the door and perpendicular to the locking axis.

So that the lock cylinder cover is reliably held on the unlocking module, it has proven to be advantageous if the unlocking module has a holding element. The holding element can preferably be arranged in the region of the receiving contour and designed as a magnet that holds the magnetizable lock cylinder cover in place. The corresponding holding force can prevent the lock cylinder cover from inadvertently pivoting and exposing the lock cylinder. If the lock cylinder is to be rotated, the lock cylinder cover must first be folded up, for which the force of the holding element must be overcome.

Furthermore, it has been found to be advantageous if the lock cylinder cover has a handling section, in particular in a direction parallel to the door, which protrudes relative to the unlocking module. Even if the lock cylinder cover is received in the receiving contour, it can be folded up by hand via the handling section. With regard to the locking and unlocking of the door, it has been found to be advantageous if the actuating lever is connected to the locking device via an actuating shaft. The actuating shaft can extend through the door and be rotatably coupled to the actuating lever. The locking device can comprise a lock case with locking rods arranged thereon, which can be moved into a locking position or an unlocking position when the operating lever is moved. In the locking position, the locking rods can engage in a fixed frame of the door or engage behind it so that the door is fixed in relation to the frame and cannot be opened. Alternatively or additionally, the locking device can have a sash which can be rotatably coupled to the actuating lever. The fastener can also intervene in the locking position to fix the door in the frame or reach behind it.

Furthermore, it has been found to be advantageous if a cover is provided to cover the unlocking module, the cover being connected, in particular releasably, to the recess or to the safety device. The cover can be connected to the recess or to the safety device from the second side of the door and thus cover the unlocking module from the second side of the door. The cover can thus protect the release module and also the safety device, for example, from contamination. The cover can be designed in the manner of a cuboid with an open side and the open side can be pushed over the unlocking module from behind. From the cover can be placed on the door or on the second side of the door. The cover can be connected to the trough and / or to the safety device via screws. Furthermore, it is also possible that the cover both with the trough and with the safety device connected is. It is not necessary for the unlocking module to be connected directly to the trough and / or to the safety device, but it can be connected to the trough and / or to the safety device via the cover. Alternatively or additionally, the cover can also be connected to the door, in particular to the second side of the door.

With regard to the arrangement of the cover, it has also proven to be advantageous if it is detachably connected to the release module. Through this connection, the release module can be fixed with respect to the trough and / or with respect to the safety device and connected via the cover to the trough and / or to the safety device. The unlocking module can have one or more fastening receptacles for connection to the cover, via which the unlocking module can be connected to the cover by means of fastening means. In practice, it has proven useful if the cover is connected to the release block via, in particular two, screws. The fastening receptacles of the unlocking module can be designed as threaded bores for receiving the threads of the screws.

In a constructive development of the invention, it has been shown to be advantageous if the release module is guided in the cover. A suitable guide facilitates the assembly and replacement of the release module. The block can not tilt due to the leadership in the cover and it is held securely on the cover from before the closing connection via the fasteners. During assembly, the cover can thus first be connected to the trough and / or to the securing device. The unlocking module can then be pushed into the cover from the first side of the door. The guiding of the cover can be be designed ner rail and, for example, comprise two webs. Furthermore, with regard to the guide, it has proven to be advantageous if it comprises four guide webs, two guide webs each being able to be arranged on opposite sides of the cover. Four guide bars allow a particularly convenient and less error-prone introduction of the unlocking modules.

With regard to the design of the securing device, it has been found to be advantageous if it has a securing pawl which engages the actuating lever to lock the actuating lever on the recess. The actuating lever can be reliably locked on the recess using the safety catch, so that the door cannot be unlocked before the lock is released. The actuating lever can have a hook section and the securing pawl or a hook end of the securing pawl can be positively connected to the hook section in the locked position and thus ensure reliable locking. The hook end of the securing pawl can be designed to correspond to the hook section of the actuating lever. The hook section of the operating lever can be arranged on the operating section on the side facing the first side of the door. The securing device can be arranged on the second side of the door, so that the hook section can extend at least in sections through the door into the securing device. It is also possible that the safety device is part of the trough. This enables uncomplicated assembly.

With regard to reliable locking, it has been shown to be advantageous if the locking pawl is biased into the locking position via a spring element. This preload enables the actuating lever to be reliably locked. The spring element can be designed as a compression spring and on the opposite of the release module lying side of the safety catch be arranged. The securing pawl can have a run-up bevel, which means that the securing pawl moves against the spring force when the actuating lever is pivoted into the recess. When the actuating lever is swiveled completely into the recess, the safety pawl can snap behind the hook portion of the actuating lever due to the preload of the spring and thus lock the actuating lever. Because of the spring element, it is not necessary to actively transfer the securing pawl into the locking position when the actuating lever is pivoted into the receiving contour.

Furthermore, it has been found to be advantageous if the safety pawl can be moved linearly. A linear movement allows a small installation space for the safety pawl or the safety device. The stroke of the safety pawl can correspond to the height of the hook section of the actuating lever, since the safety pawl has to be raised by the height of the hook section to release the hook section. Furthermore, in order to ensure reliable movement of the safety pawl, the safety pawl can be guided in a guide, in particular a linear guide. The guide ensures that the safety catch works reliably so that it cannot tilt. It is advantageous if the locking pawl is moved against the force of the Federele element in the guide when unlocking. The securing pawl can then be moved linearly and lifted off the hook section, so that the actuating lever and the securing pawl disengage and the actuating lever can be pivoted out of the recess. The securing pawl can have a bevel in the area of the hook end, which is designed in such a way that the hook section of the actuating lever moves the securing pawl against the spring force when the actuating lever is pivoted into the recess, so that the hook section and the hook end automatically engage with one another. In an alternative embodiment, the securing pawl can also be rotatable. Although this configuration requires a larger construction space, there is a risk that the locking pawl tilts, ge ringer. Accordingly, in this embodiment, no additional Füh tion is required, but the safety pawl can be mounted at a pivot point of the safety device. In this embodiment, the spring element can be arranged on the opposite side of the pivot point from the hook end of the securing pawl, and in particular press the hook end upwards. In the unlocking then the hedging pawl can be rotated against the force of the spring element about a pivot point until the hook end releases the hook portion.

With regard to the design of the unlocking module, it has proven to be advantageous if it has an unlocking finger which can be moved into an unlocking position when the lock cylinder is rotated. By means of the unlocking finger, the securing pawl can be moved against the spring force of the spring element and the corresponding hook end can be disengaged from the hook section. The unlocking finger can insofar ensure that the locking pawl is raised or rotated about the axis of rotation and the hook end is lifted off the hook section. If the securing pawl is rotatable, the unlocking finger can lift the part of the securing pawl which is opposite the hook end, so that the hook end is pivoted downward and the actuating lever is released.

The unlocking finger can also be rotatably coupled to the lock cylinder and extend in the radial direction to the lock axis. The unlocking module can have a spring element which biases the unlocking finger and / or the lock cylinder into the locking position. The spring element can be designed as an axial spring. At a When the locking cylinder is rotated from the locking position to the unlocking position, the spring is tensioned so that the locking cylinder itself can constantly return to the unlocking position.

With regard to the object mentioned at the beginning, a method for assembling a modular locking system for a door is also proposed. The locking system comprises a trough which can be arranged on a first side of the door, an actuating lever which can be pivoted relative to the trough for actuating a locking device which can be arranged on the other side of the door to lock the door, a safety device for locking the operating lever to the trough and an unlocking device Stone to release the lock, whereby the release module is attached to the trough as a trough extension.

The modular locking system can be designed in the above-described Wei se and the above-described parts result.

During assembly, the trough with the operating lever arranged thereon can first be mounted on an opening in the door. In a next step, the cover can then be connected to the recess and / or the safety device from the second side of the door. The unlocking module can then be placed in an opening in the door below or, alternatively, above the trough as a trough extension on the trough. The unlocking module then extends through the door and is covered on the second side of the door by the cover or received in the cover. Finally, the unlocking module is then connected to the cover via the fastening means.

With regard to dismantling, it has been found to be advantageous if the actuating lever is first pivoted out of the trough must before the release module can be removed. This prevents unauthorized removal of the unlocking module. To dismantle the locking system or the unlocking module, the fastening means that connect the unlocking module to the cover must first be released. However, even if the fastening means are loosened, it is not possible to remove the unlocking module. Because the actuating section of the actuating lever covers the release module in the pivoted position. Accordingly, the Entsi cherungsbaustein can only be pulled out when the locking of the actuating lever is released and this is pivoted out of the recess. In this respect, it is also necessary to remove the release module that a suitable key or a suitable tool to rotate the lock cylinder is available and it is not enough to loosen the fastening means through which the release module is connected to the cover.

In an alternative embodiment, the unlocking module can also be removed when the connection between the unlocking module and the cover is released. The actuating section then does not prevent the release module from being pulled out of the cover, but only the lock cylinder cover has to be folded up.

Furthermore, with regard to the aforementioned object, a door with a modular locking system is proposed, the locking system being designed in the manner described above. The advantages already described with regard to the locking system result.

With regard to the door, it has been found to be advantageous if the se has two openings. An opening can be used to connect the actuator Serve transmission lever with the locking device and the actuating shaft can extend through this opening. The unlocking module can extend through the second opening. Alternatively, the door can also have only one opening.

When the unlocking module is attached to the recess, it can rest on one side of the recess or on the safety device and on the other three sides of the door. The collar-shaped support area can rest on the door in the area of the edge of the opening of the door and the remaining part of the release module can extend through the opening of the door.

Further advantages and developments of the invention will be explained in more detail below with reference to the accompanying drawings. Show:

10a, b are perspective views of a cover.

The representations of FIGS. 1 a and 1 b show a modular locking system 10 in a perspective side view with various release modules 4, which can be used in the locking system 10 as desired.

The locking system 10 consists essentially of a trough 1 and an actuating lever 2 which can be pivoted with respect to the trough 1 and which is shown in a pivoted-out position in the illustration in FIG. 1a. The locking system 10 is arranged on the front 101 of a door 100, but extends partially through this door 100, as can be seen in the illustration of FIG. 1b. The door 100 has two rectangular openings, part of the trough 1 and an actuating shaft 6 extending through the upper opening, as can also be seen in the sectional view of FIG. 7a. The actuating shaft 6 is connected to a locking device 8 arranged on the other side 102 of the door 100, as is the case with regard to the other figures will be described in more detail. The lower opening of the door 100, which can be seen in FIG. 1 a, is used to accommodate one of the several unlocking modules 4. Depending on which unlocking module 4 is to be used to unlock the door 100, it can be used below the recess 100 and then like to extend the trough 1 downwards.

As can also be seen in FIGS. 1a and 1b, a cover 5 is also provided, which covers the lower opening of the door 100 from the direction of the second side 102 of the door 100, so that the unlocking module

4 can be inserted into the door from the front and then from the cover

5 is covered. To connect the release module 4 with the cover from 5 fasteners designed as screws 7 are vorgese hen. After an unlocking module 4 has been selected and inserted into the opening of the door 100, the corresponding unlocking module 4 can be detachably connected to the cover 5 via the fastening means 7. In order to exchange the release module 4 for another release module 4, the fastening means 7 must first be loosened in reverse order, the actuating lever 2 swiveled out of the recess 1 and the release module 4 then forward out of the cover 5 or from the lower opening the door 100 can be pulled out.

As can be seen in the illustration in FIG. 2, the actuating lever 2 is received in the trough 1 in a pivoted-in position.

For this purpose, the trough 1 has a trough receptacle 1.1, as can be seen, for example, in FIG. 4 or in FIG. 1a. When the actuating lever 2, as shown in FIG. 2, is positively received in the recess 1.1, the actuating lever 2 cannot be moved and thus the door 100 cannot be unlocked. In order to move the actuating lever 2 around the actuating axis B as shown in FIG. pivot, it is first necessary to pivot this out of the receiving contour 1.1 about the pivot axis S. Because as it is based on Fig.

7 and 8 is described in more detail below, the actuating lever 2 is locked in the swiveled-in position by a securing device 3 in the trough 1 or in the receiving contour 1.1 of the trough 1. This locking can, however, be released again via the unlocking module 4, so that the actuating lever 2 can then be swiveled out of the recess 1 and pivoted about the actuating axis B to actuate the locking device 8. The securing device 3 is connected to the trough 1 and is arranged essentially on the side 102 of the door 100; although the cover 5 does not allow the securing device 3 to be seen in FIGS. 1b and 6a, 6b, it can be seen in the sectional views of FIG 7 and 8.

As can be seen from the illustration in FIG. 3, the loading actuating lever 2 consists essentially of two elements, namely a loading actuating section 2.2, which is connected at one end to the actuating shaft 6, and a lock cylinder cover 2.1, which is pivotable with the actuating section 2.2 is connected. In the pivoted-in position, the lock cylinder cover 2.1 covers a lock cylinder 4.3 of the unlocking module 4, so that for unlocking it is first necessary to fold up the lock cylinder cover 2.1, as shown in the illustration in FIG. 3. When the lock cylinder cover 2.1 is folded up, the lock cylinder 4.3 becomes visible and this can be turned with a key, for example, as is known from normal house locks.

In the embodiment according to FIG. 4, two different release modules 4 are arranged below the trough 1. Although the two security modules 4 have a similar locking cylinder 4.3, a different key is required for each unlocking. borrowed. The background to this is that the door 100 should be opened by two different people or by two different groups of people, but not all people should receive the same key. The two release modules 4 are therefore connected to the safety device 3 in such a way that it is sufficient to rotate only one of the two release modules 4 or the corresponding lock cylinder 4.3 in order to be able to pivot the actuating lever 2 out of the recess 1.1.

As can also be seen in the illustration of FIG. 3, not only does the trough 1 have a receiving contour 1.1, but also the securing module 4 has a corresponding receiving contour 4.2, which ensures that the actuating lever 2 or the lock cylinder cover 2.1 in the swiveled-in position is not only flush with the trough 1, but also flush with the release module 4. Nevertheless, the actuating lever 2 has at one end a handling section 2.4 which protrudes downward over the lowermost release module 4. This handling section 2.4 can thus be used to reach behind the lock cylinder cover 2.1 with one hand and then fold it up to the front so that the lock cylinder 4.3 is accessible.

The design of an unlocking module 4 will now be explained in more detail below with reference to FIGS. 5a and 5b. Another embodiment of the releasing module is described in more detail below with reference to FIGS. 9a and 9b. The release module 4 shown in the representations of FIGS. 5a and 5b corresponds to the middle release module 4, which is shown in FIGS. 1a and 1b. The other unlocking modules 4 may have differently designed locking cylinders 4.3 - for example, it can be seen in FIG. 1 a that the two right unlocking modules 4 tend to have a Tool than can be turned with a key - the basic structure of the release blocks 4 is however identical. For this reason, only the middle unlocking module 4 of FIG. 1 a b is described in more detail below by way of example with reference to FIGS. 5 a and 5 b.

As can be seen first of all, the unlocking module 4 has two profiles 4.1 protruding relative to the receiving contour 4.2 on its front side. These profiles 4.1 ensure that the actuating lever 2 cannot be rotated about the actuating axis B, but must first be pivoted forward around the pivot axis S out of the receiving contour 4.2 and also out of the receiving contour 1.1 of the trough 1.

In order to hold the lock cylinder cover 2.1 in the receiving contour 4.2, the unlocking module 4 has a holding element 4.4 designed as a permanent magnet in the lower part of the receiving contour 4.2. When the lock cylinder cover 2.1, as shown in FIG. 2, lies in the receiving contour 4.2 of the unlocking module 4, this holding element 4.4 ensures that the lock cylinder cover 2.1 is not unintentionally pivoted upwards relative to the actuating section 2.2. In order to expose the lock cylinder 4.3, the holding force of the holding element 4.4 must then be overcome when the lock cylinder cover 2.1 is swung up.

As can also be seen, the lock cylinder 4.3, which can be rotated about the unlocking axis E via a key, is connected to a Entsicherungsfin ger 4.5, which is arranged radially vorsprin low with respect to the unlocking axis E. When the lock cylinder 4.3 is rotated, the unlocking finger 4.5 also moves accordingly and can then unlock the safety device 3. Furthermore, two fastening mounting receptacles 4.8 are shown in Fig. 5b, which are designed as threaded holes so that the fastening means 7 from the outside through the cover 5 in the two fastening receptacles 4.8 are screwed in and the Ent fuse module 4 can thus connect to the cover 5.

It can also be seen that the unlocking module 4 has a support area 4.6 which extends on three sides of the unlocking module 4. When the unlocking module 4, for example as shown in FIG. 1 a, is inserted into the opening in the door 100, this collar-shaped support area 4.6 rests on the outside 101 of the door 100 and the remaining part of the unlocking module 4 extends through the door 100. The unlocking module 4 thus rests against the door 100 on three sides.

As can also be seen in the illustration of FIG. 4, in the case of several unlocking modules 4 arranged one below the other, they can have a slightly different outer contour and thus also a different support area 4.6. For example, the upper unlocking module 4 rests on only two sides on the outside 101 of the door 100, but the lower unlocking module 4 also rests on a lower side and thus on three sides on the door 100. The upper release module 4 is designed as an intermediate piece and the lower release module 4 is designed as an end piece.

As can be seen from FIGS. 6a and 6b, the actuating shaft 6 is connected to a locking device 8 on the inside 102 of the door 100. In a locked position, the locking device 8 can fix the door 100 with respect to a door frame, so that the door 100 cannot be opened. In an unlocked position, the locking device 8 can allow a corresponding movement of the door 100 so that it can be opened. As can also be seen, the locking device 8 can be designed differently. The illustration in FIG. 6a shows this, for example, as a lock case 8.2 formed two locking rods. In the embodiment according to FIG. 6 b, the locking device 8 is designed as a sash fastener 8.1, which is connected to the actuating lever 2 in a rotatable manner. In this respect, the modular locking system 10 enables not only a modular exchange of the unlocking modules 4, but also a modular exchange of the locking device 8, depending on the requirements placed on the locking system 10.

The more detailed internal structure of the locking system 10 will now be described below with reference to FIGS. 7a, 7b and 8a, 8b.

In the illustration of FIG. 7a, the locking system 10 is shown in a side sectional view. The operating lever 2 is pivoted about the pivot axis S from the receiving contour 1.1 of the trough 1 and from the receiving contour 4.2 of the release module 4 and can be rotated in this position about the operating axis B to lock or unlock the door. As can also be seen, the Actuate transmission lever 2 or the actuating section 2.2 has a hook section 2.3 which protrudes inward, that is, in the direction of the trough 1. When the operating lever 2 is pivoted about the pivot axis S and pressed into the receptacle contour 1.1 of the trough 1, the hook section 2.3 interacts with the securing device 3 in such a way that it locks the actuating lever 2 in the trough 1. This position is shown in Fig. 7b represents.

The securing device 3 has a securing pawl 3.1 which has a hook-shaped end 3.5 at one end. In the pivoted-in position shown in FIG. 7b, this hook end 3.5 is in engagement with the Hakenab section 2.3 of the operating lever 2, so that the operating lever 2 can no longer be pivoted out of the trough 1 about the pivot axis S. To unlock the door 100, the operating lever 2 first swiveled out of the trough 1 and transferred to the position shown in Fig. 7a Darge. For this purpose, the hook end 3.5 of the securing device 3 and the hook section 2.3 of the actuating lever 2 must first be disengaged again.

The safety catch 3.1 is guided in a guide 3.3 and can therefore be moved linearly. The securing pawl 3.1 and thus also the hook end 3.5 are biased into the locking position via a spring element 3.2 designed as a compression spring. If the lock cylinder 4.3 of the release module 4 is now rotated about the unlocking axis E, the release finger 4.5 comes into contact with the locking pawl 3.1 and moves it in the guide 3.3 against the spring force of the spring element 3.2. When the lock cylinder 4.3 has been rotated far enough, the locking pawl 3.1 is moved so far that the hook end 3.5 and the hook section 2.3 are no longer in engagement and the actuating lever 2 then

The pivot axis S can be pivoted out of the trough 1. The various unlocking modules 4 all have a similar unlocking finger 4.5 which moves the locking pawl 3.1 when the lock cylinder 4.3 moves in such a way that the locking of the actuating lever 2 is released. In this respect, it is not necessary to change or adapt the safety device 3 when the release module 4 is replaced.

In the embodiment shown in the illustration of FIGS. 8a and 8b, the locking system 10 basically functions in exactly the same way as previously described with regard to FIGS. 7a and 7b. Only the design of the securing device 3 is different. Because the se does not have a linearly movable safety pawl 3.1, but the safety pawl 3.1 is pivotably mounted about a pivot point 3.4. In the locked position, which is shown in Fig. 8b, the hook engages de 3.5 of the safety pawl 3.1 from below into the hook section 2.3 of the Operating section 2.2 and thus holds the operating lever 2 on or locked in the receiving contour 1.1 of the trough 1. The rotationally movable safety pawl 3.1 is biased into the locking position via a spring element 3.2 so that it is then pivoted about the pivot point 3.4 when the lock cylinder 4.3 is rotated by the unlocking finger 4.5, so that the hook end 3.5 and the hook section 2.3 except Intervention. This sectional view also clearly shows the downwardly protruding handling section 2.4, which must be folded up before the lock cylinder 4.3 is rotated, as has already been described above with regard to FIGS. 2 and 3.

In both configurations, the actuating section 2.2 covers an upper edge of the unlocking module 4 at its lower end. Accordingly, the unlocking module 4 can only be pulled out of the cover 5 or from the door 100 if, on the one hand, the fastening means 7 are released and In addition, the actuation lever 2 or the actuation section 2.2 is pivoted out of the trough 1. In this respect, it is not possible to remove the release module 4 without having turned the lock cylinder 4.3 into the release position using the appropriate key. Even if a person has, for example, access to the fasteners 7, it is necessary to remove the Entsicherungsbau stone 4 that this person also sits the correct key be.

The unlocking module 4 shown in FIGS. 9a and 9b essentially corresponds to the unlocking module 4 which has already been described with regard to FIGS. 5a and 5b or also to those which are shown in FIGS. 1a and 1b. In addition, however, the unlocking module 4 of FIGS. 9a and 9b has two guide bolts 4.9 via which the unlocking module 4 can engage in the trough 1 at the upper end. The trough 1 has a corresponding receptacle into which the guide pins 4.9 when inserting stuck into the trough. The release modules 4 can thus also be guided in the trough 1 via the guide pins 4.9.

Furthermore, in the perspective illustration of FIGS. 10 a and 10 b, the cover 5 is shown in an enlarged view. The side walls of the cover 5 have guide webs 5.1 on their inside, on which the release blocks 4 can be supported when pushed into the cover 5. As can be seen, four guide webs 5.1 are provided, two guide webs 5.1 being arranged on opposite sides of the cover 5.
