Description

[0001] The invention relates to a mechanical lock with an additional electronic module according to the features of the preamble of claim 1 and to a method for locking and unlocking a mechanical lock with an additional electronic module according to the features of the preamble of claim 14.

[0002] WO 2013 / 114 409 A1 discloses a lock that can be adapted to specific circumstances. It is provided that individual extensions can be connected to the lock housing, which can, for example, include additional locking elements or drive devices, thus expanding the lock housing. This makes it possible to individually upgrade the lock and adapt it to increased security requirements. However, the lock housing mount in the door must be designed to match the enlarged lock housing. EP 3 299 552 A1 discloses a motor lock with a drive module that motor-actuates the entire lock mechanism via a slide plate for locking or unlocking.

[0003] Electronic add-on modules are also known, which can be installed outside the lock housing. The add-on module moves parts of the lock mechanism in a lock using an electronic drive. This movement drives the lock mechanism, thus locking or unlocking the lock. The disadvantage of such add-on modules is that the electronic drive usually affects the entire lock mechanism.

[0004] In practice, electric strikes are also used, which are installed in the door frame and interact with a mechanical lock to open or close electrically controlled doors. A key criterion for such electric strikes is, on the one hand, the volume of the electric strike and, on the other hand, the holding force that can be achieved with the electric strike. The disadvantage here is that a corresponding recess must be created in the frame for the electric strike.

[0005] The present invention is based on the object of providing a mechanical lock with an additional electronic module that covers a wide range of applications and is easy to manufacture. A further object of the present invention is to eliminate the need for a separate door opener and replace it with a lock.

[0006] The object is achieved according to the invention by a mechanical lock with an additional electronic module according to the features of claim 1.

[0007] According to the invention, a mechanical lock for a pivoting leaf of a door or window is provided with an additional electronic module, wherein the lock has a lock housing and a lock mechanism arranged therein with a lockable lock latch and the lock has a blocking element movable by the lock mechanism, and wherein the blocking element can be displaced by the lock mechanism into a blocking position in which the blocking element engages behind the lock latch and a movement of the lock latch is blocked, and wherein the blocking element can be displaced by the lock mechanism into a release position in which the lock latch is pivotable and translationally displaceable, and The electronic module is located in the lock housing. It is important that the electronic module prevents a purely mechanical opening of the door by the electronic additional module has a switchable displacement element which prevents or allows displacement of the blocking element by the lock mechanism, and / or that the additional electronic module has a movable electronic module blocking element which prevents or allows the lock latch to be moved.

[0008] Furthermore, the object is achieved by a method for locking and unlocking a mechanical lock with an additional electronic module according to the features of claim 14.

[0009] According to the invention, a method for locking and unlocking a mechanical lock for a pivotally mounted leaf of a door or window with an additional electronic module is proposed, comprising locking or unlocking a lock latch by displacing a blocking element by a lock mechanism of the lock, wherein the blocking element can be displaced by the lock mechanism into a blocking position in which the blocking element engages behind the lock latch and a movement of the lock latch is blocked, and wherein the blocking element can be displaced by the lock mechanism into a release position in which the lock latch is pivotable and translationally displaceable. It is essential that the electronic additional module prevents a purely mechanical opening of the door by the lock mechanism by preventing or allowing a transfer of the movement of the lock mechanism to the blocking element by means of a switchable displacement element, and / or by the electronic additional module preventing or allowing the displacement of the lock latch by means of a movable electronic module blocking element.

[0010] The advantage of the device and method according to the invention is that the electronic add-on module directly affects the locking or unlocking of the lock latch, thus preventing a purely mechanical opening of the door by the lock mechanism alone via an electronic control system. A further advantage is that the electronic add-on module does not affect the entire lock mechanism.

[0011] A further advantage of the device and method according to the invention is that the functionality of the purely mechanical lock is expanded by the additional electronic module, whereby additional components, such as a door opener, can be replaced by the lock according to the invention with the additional electronic module and the method according to the invention. This eliminates the need to create an opening in the frame for the door opener. Another advantage is that replacing the lock with the additional electronic module as a door opener results in a much higher holding force compared to conventional door openers, since the latch interacts with a latch receptacle of a frame and not with the moving parts of a door opener.

[0012] A further advantage is that the lock can be operated as a fully functional, purely mechanical lock without the additional module. The lock can be upgraded at any time—during its manufacture, during assembly, or at a later date, i.e., after the lock has been installed and commissioned.

[0013] A production kit comprising the lock and the additional electronic module can also be provided for distribution. Alternatively, the additional electronic module can be sold separately from the lock, allowing an already installed lock to be retrofitted with a corresponding additional electronic module.

[0014] By electronically blocking or releasing the lock latch by the additional electronic module, it is possible to use the lock according to the invention with the additional electronic module and the method according to the invention in escape doors and for escape door security.

[0015] When the door is locked, the latch is in its pre-locked position, with the blocking element engaging behind the latch in a blocked position, so that the latch is fixed and cannot be pushed into the lock housing. When the door is unlocked, the blocking element is in a released position, allowing the latch to be pushed into the lock housing.

[0016] The electronic additional module may be provided with a motor, preferably an electric motor or a coil, as the drive. The electronic additional module may be provided with a gear for transmitting a movement of the drive to the switchable displacement element or the electronic module blocking element.

[0017] It can be provided that the electronic module blocking element can be displaced by a drive of the electronic module into a blocking position in which the electronic module blocking element engages behind the lock latch and a movement of the lock latch is blocked, and wherein the electronic module blocking element can be displaced by the drive of the electronic module into a release position in which the lock latch is pivotable and translationally displaceable.

[0018] When the door is locked, the lock latch is in its pre-locked position, with the electronic module blocking element engaging behind the lock latch in a blocked position, so that the lock latch is fixed and cannot be inserted into the lock housing. When the door is unlocked, the electronic module blocking element is in a released position, so that the lock latch can be inserted into the lock housing.

[0019] It can be provided that the blocking element and / or the electronics module blocking element are designed as a linearly displaceably mounted blocking slide and / or electronics module blocking slide, or have a linearly displaceably mounted blocking slide and / or electronics module blocking slide. It can be provided that the linearly displaceably mounted blocking slide of the blocking element and / or the electronics module blocking slide causes the release or blocking of the lock latch.

[0020] The blocking element and / or the electronic module blocking element can also be designed as a rotatably mounted element having a blocking section that can be selectively pivoted into or out of the movement range of the lock latch. It can be provided that the rotatably mounted element of the blocking slide and / or the electronic module blocking slide causes the lock latch to be released or blocked.

[0021] It can be provided that the blocking element and / or the electronic module blocking element is / are mounted perpendicular to the movement of the lock latch.

[0022] It can be provided that two rollers are each rotatably mounted on the blocking element and / or the electronics module blocking element, preferably on the blocking slide and / or on the electronics module blocking slide, wherein the bearing axes of the two rollers are parallel to one another, and wherein the two rollers contact one another. It can be provided that the two rollers are each arranged on a blocking slide of the blocking element and / or the electronics module blocking element. It can be provided that in the blocking position, the blocking slide engages behind the lock latch such that one of the two rollers rests on the rear edge of the lock latch, wherein the rollers assume a dead center position with respect to the rear edge of the lock latch. This is possible in that the directions of movement of the lock latch and of the blocking element and / or the electronics module blocking element are perpendicular to one another.The lock latch cannot be moved by an external force acting on it, as the force is introduced into the two rollers that are in the dead center position.

[0023] An advantage is that the two rollers can absorb high forces in their dead-center position. This allows for a lock with high resistance. Moving the two rollers away from the dead-center position, however, causes the lock latch to be securely released. To move the two rollers away from the dead-center position, it is sufficient, for example, to move only one of the two rollers, preferably along the rear edge of the lock latch. The two rollers can also be moved out of engagement with the lock latch, or the two rollers can be tilted.

[0024] In particular, it can be provided that the blocking element and the electronic module blocking element are constructed identically with respect to the two rollers. The blocking element and the electronic module blocking element can both act on the rear edge of the lock latch. The lock latch can be blocked either solely by the blocking element, solely by the electronic module blocking element, or simultaneously by both the blocking element and the electronic module blocking element. Preferably, the lock latch is released when both blocking elements—i.e., the blocking element and the electronic module blocking element—release the lock latch.

[0025] It can be provided that the displacement element forms a switchable locking mechanism between the lock mechanism and the blocking element, wherein when the transmission of the movement is permitted, the locking mechanism is formed between the lock mechanism and the blocking element and when the transmission of the movement is prevented, the locking mechanism between the lock mechanism and the blocking element is released.

[0026] In one exemplary embodiment, it can be provided that the blocking element is biased toward the blocking position by a spring. In such an embodiment, the blocking element is in the blocking position by decoupling from the lock mechanism and can be transferred to the release position by the switchable displacement element by coupling it to the lock mechanism.

[0027] It can be provided that the displacement element is designed in such a way that when the transmission of movement is permitted, the displacement of the blocking element is not compensated by the lock mechanism, and when the transmission of movement is prevented, the displacement of the blocking element is compensated by the lock mechanism, wherein the compensation is achieved by a movement of the displacement element in the additional electronic module. Such compensation can be achieved, for example, by a drive with a spindle and a spindle nut, in that the rotary movement of the drive is converted into a linear movement of the spindle nut in order to compensate for a linear movement of the lock mechanism for actuating the blocking element. It can be provided that the additional electronic module is arranged with a displacement element on the blocking element or on a movable component of the lock mechanism.With such an arrangement, the additional electronic module can compensate for any movement of the lock mechanism used to actuate the blocking element.

[0028] The lock latch can be designed as a tilt latch, a cross latch, or a roller latch. A tilt latch is understood to be a lock latch with a latch head and a latch carrier, wherein the latch head is pivotally mounted on the latch carrier. A cross latch is understood to be a lock latch with a multi-part latch head and latch carrier, wherein the multiple parts of the latch head are pivotally mounted on the latch carrier according to an opening or closing direction of the door. A roller latch is understood to be a lock latch with a roller as the latch head, which is mounted on a latch carrier. The latch carrier of the respective lock latch is, for example, mounted in the lock housing so that it can move linearly. Depending on the design, the latch head has an inlet bevel and an outlet bevel.A lock equipped with a tilt latch can be used on left-hinged doors as well as right-hinged doors.

[0029] It can be provided that the lock has a locking element that can be actuated by the locking mechanism, and the locking element can be actuated by a slide plate of the lock mechanism between a pre-locked locking position and an unlocking position retracted into the lock housing.

[0030] The lock mechanism can be provided with a central slide plate, which serves to control the locking element and the blocking element. The locking element can be locked via a guide slot arranged in the slide plate, which interacts with a pin of the locking element.

[0031] Furthermore, the lock mechanism can comprise a locking cylinder and / or a handle nut, as well as gear elements to transmit a movement of the locking cylinder or the handle nut to the locking element and / or the blocking element.

[0032] The lock may be provided with a handle for operating the lock mechanism via the handle nut.

[0033] The handle may be designed as a door handle or push bar.

[0034] It can be provided that the lock has a locking sensor which detects the position of the locking element, preferably the pre-locked locking position and / or the retracted unlocking position.

[0035] It can be provided that the handle can be used to move both the locking element into the unlocking position and the blocking element into the release position. A function of this type is intended for a door as an escape route security device for use in escape and rescue routes. A lock with this type of function is also called a panic lock. A panic lock has a locking element, a lock latch and a follower connected to a handle, as well as a locking cylinder. When the panic lock is locked, i.e. when the bolt is in its pre-locked position and engages in a bolt recess in the door frame, the lock can only be opened manually by a user from the inside of the building by operating the handle. Turning the follower causes the locking element to move back into its closed position in the lock housing and the lock latch to be released.A panic lock doesn't require a key to unlock it from inside the building. A locking cylinder, which can be turned with a key, is used to lock the lock. Typically, only a handle and a locking cylinder are located on the outside of the panic lock housing.

[0036] In order to provide a panic lock that has different panic functions, it can be provided that the handle nut is designed as a multi-part handle nut, ie has at least two nut parts and also a pawl or several pawls for coupling and / or uncoupling the nut parts.

[0037] The lock housing may be designed as a built-in housing. It includes a lock faceplate, a lock base, and a removable lock cover.

[0038] It can be provided that the additional electronic module is arranged on the lock housing, preferably the lock base.

[0039] The mechanical receptacles of the lock housing can, for example, be designed as form-fitting receptacles into which the additional electronic module is inserted. Alternatively or additionally, the mechanical receptacles can also be designed as screw connections, snap-in connections, or clip connections. Riveting to accommodate and hold the additional electronic module is also possible in this regard.

[0040] One embodiment may provide for the lock to have a control latch, a spring that acts on the control latch, and at least one gear element that can be actuated by the control latch to connect the control latch to the lock mechanism, preferably to the slide. For example, the locking element and / or the lock latch can be controlled via the control latch to trigger locking of the locking element in a self-locking lock as soon as the door is in the closed position. Furthermore, the control latch can have a sequence control that includes tamper protection and prevents the locking element from being locked out of the lock housing if the control latch is accidentally actuated while the door is still open.

[0041] It may be provided that the additional electronic module is connected to a power supply line and / or control line.

[0042] The electronic add-on module can be controlled by a door control panel or a door terminal located near the door with the lock. The electronic add-on module can also be controlled, either in addition to or alone, by a remote control panel. The remote control panel can be connected to the lock or the electronic add-on module via cable or bus.

[0043] Further embodiments of the invention are illustrated in the figures and described below. The figures show a possible embodiment of the invention by way of example. This embodiment serves to illustrate a possible implementation of the invention and is not intended to be limiting.

[0044] Fig. Figure 1 shows a door 3, which is mounted on hinges on a door frame 4. A lock 1 with a lock latch 11 is arranged in a lock receptacle of the door 3.

[0045] Fig. 2 shows a first embodiment of the lock 1 according to the invention with an additional electronic module 2, wherein in this embodiment the additional electronic module 2 has a displaceable electronic module blocking element 12 and thereby prevents or allows the displacement of the lock latch 11.

[0046] The lock 1 has a lock housing 10 with a lock mechanism arranged therein and the lockable lock latch 11. The lock latch 11 is in the embodiment of the Fig. 2 is designed as a tilt latch 17, which is pivotably mounted on a latch support 15. The latch support 15 of the tilt latch 17 is mounted in the lock housing 10 for linear movement. The direction of movement of the latch support 15 is horizontal in the installed position of the lock 1, wherein the direction of movement of the latch support 15 and the tilt latch 17 mounted thereon is parallel to the direction of movement of a Fig. 2 not shown locking element. The pivot axis of the tilt latch 17 runs parallel to the extension axis of a faceplate of the lock 1 and perpendicular to the direction of movement of the latch carrier 15. The latch carrier 15 is acted upon by a spring 16 supported on the lock housing 10, which urges the latch carrier 15 towards its extended position, as in Fig. 2 shown.

[0047] A blocking element 12, which is movable by the lock mechanism, is arranged in the lock housing 10. In the embodiment of the Fig. 2, the blocking element 12 is designed as a blocking slide 13. Furthermore, the electronic additional module 2 is arranged in the lock housing 10, which has the electronic module blocking element 20. The electronic module blocking element 20 is in the embodiment of the Fig. 2 is designed as an electronic module blocking slide 23.

[0048] In the example of Fig. 2, two blocking slide rollers 14 are rotatably mounted on the blocking slide 13. Furthermore, two electronic module blocking slide rollers 24 are rotatably mounted on the electronic module blocking slide 23. The bearing axes of the two blocking slide rollers 14 and the two electronic module blocking slide rollers 24 are parallel to each other, with the two blocking slide rollers 14 of the blocking slide 13 or the two electronic module blocking slide rollers 24 of the electronic module blocking slide 23 contacting each other, as shown in Fig. 2 shown.

[0049] In Fig. 2, the blocking element 12 is arranged in the blocking position, in which the blocking slide 13 with the blocking slide rollers 14 of the blocking element 12 engages behind the lock latch 11 and a movement of the lock latch 11 is blocked. Furthermore, in Fig. 2 the electronic module blocking element 20 is arranged in the blocking position, in which the electronic module blocking slide 23 with the electronic module blocking slide rollers 24 of the electronic module blocking element 20 engages behind the lock latch 11 and a movement of the lock latch 11 is blocked.

[0050] In the blocking position of the blocking element 12 in Fig. 2, the blocking slide 13 of the blocking element 12 engages behind the lock latch 11 such that one of the two blocking slide rollers 14 rests against the rear edge of the lock latch 11, with the blocking slide rollers 14 assuming a dead center position with respect to the rear edge of the lock latch 11. This is possible because the directions of movement of the lock latch 11 and the blocking element 12 are perpendicular to each other. Therefore, the lock latch 11 cannot be moved by an external force acting on the lock latch 11, since the force is introduced into the two blocking slide rollers 14 in the dead center position.

[0051] This applies equally to the electronic module blocking element 20 in Fig. 2. In the blocking position of the electronic module blocking element 20 in Fig. 2, the electronic module blocking slide 23 of the electronic module blocking element 20 engages behind the lock latch 11 such that one of the two electronic module blocking slide rollers 24 rests against the rear edge of the lock latch 11, with the electronic module blocking slide rollers 24 assuming a dead center position with respect to the rear edge of the lock latch 11. This is possible because the directions of movement of the lock latch 11 and the electronic module blocking element 20 are perpendicular to one another. Thus, the lock latch 11 cannot be moved by an external force acting on the lock latch 11, since the force is introduced into the two electronic module blocking slide rollers 24 in the dead center position.

[0052] Fig. 3 shows the lock 1 according to the invention with additional electronic module 2 from Fig. 2, where in the Fig. 3 the blocking element 12 is in the release position and the electronic module blocking element 20 is in the release position. When both the blocking element 12 and the electronic module blocking element 20 are in the release position, the lock latch 11 is pivotable and translationally displaceable, ie, the lock latch 11 can be inserted into the lock housing 10.

[0053] In this embodiment, the locking element 12 is moved into the release position by the lock mechanism. In this embodiment, the electronic module locking element 20 is moved into the release position by a drive of the additional electronic module 2.

[0054] In the release position of the blocking element 12, the blocking slide rollers 14 on the blocking slide 13 do not engage behind the lock latch 11, as in Fig. 3, in which the blocking slide rollers 14 in the embodiment of the Fig. 3 have been displaced by the blocking slide 13 from the area of ​​the rear edge of the lock latch 11. Moving the two blocking slide rollers 14 from the dead center position causes the lock latch 11 to be safely released.

[0055] This applies equally to the electronic module blocking element 20. In the release position of the electronic module blocking element 20, the electronic module blocking slide rollers 24 on the electronic module blocking slide 23 do not engage behind the lock latch 11, as in Fig. 3, in which the electronic module blocking slide rollers 24 in the embodiment of the Fig. 3 have been displaced from the rear edge of the lock latch 11 by the electronic module blocking slide 23. Moving the two electronic module blocking slide rollers 24 from the dead center position causes the lock latch 11 to be safely released.

[0056] Fig. 4 shows the lock 1 according to the invention with additional electronic module 2 from the Fig. 2 and Fig. 3, where in the Fig. 4 the blocking element 12 is in the blocking position and the electronic module blocking element 20 is in the release position.

[0057] Fig. 5 shows the lock 1 according to the invention with additional electronic module 2 from Fig. 2 to 4, with the Fig. 5 the blocking element 12 is in the release position and the electronic module blocking element 20 is in the blocking position.

[0058] The lock latch 11 can be blocked either only by the blocking element 12 ( Fig. 4), or only by the electronic module blocking element 20 ( Fig. 5) or simultaneously by the blocking element 12 and the electronic module blocking element 20 ( Fig. 3). A release of the lock latch 11 in the embodiment of the Fig. 2 to 5 occurs when both blocking elements, i.e. the blocking element 12 and the electronic module blocking element 20, release the lock latch 11.

[0059] Fig. 6 shows a second embodiment of the lock 1 according to the invention with an additional electronic module 2, in which the additional electronic module 2 prevents or allows a transmission of the movement of the lock mechanism to the blocking element 12 by means of a switchable electronic module displacement element 25.

[0060] The Castle 1 in Fig. 6 has a lock housing 10 with a lock mechanism arranged therein and the lockable lock latch 11. The lock latch 11 is designed in this embodiment as a tilt latch 17 which is pivotably arranged on a latch carrier 15. The latch carrier 15 of the tilt latch 17 is mounted linearly movable in the lock housing 10. The direction of movement of the latch carrier 15 is the horizontal direction in the installed position of the lock 1, wherein the direction of movement of the latch carrier 15 and the tilt latch 17 mounted thereon is parallel to the direction of movement of a Fig. 6 not shown locking element. The pivot axis of the tilt latch 17 runs parallel to the extension axis of a faceplate of the lock 1 and perpendicular to the direction of movement of the latch carrier 15. The latch carrier 15 is acted upon by a spring 16 supported on the lock housing 10, which urges the latch carrier 15 towards its extended position, as in Fig. 6 shown.

[0061] A blocking element 12, which is movable by the lock mechanism, is arranged in the lock housing 10. In the embodiment of the Fig. 6, the blocking element 12 is designed as a blocking slide 13. In the embodiment of Fig. 6, two blocking slide rollers 14 are rotatably mounted on the blocking slide 13. The bearing axes of the two blocking slide rollers 14 are parallel to each other, with the two blocking slide rollers 14 of the blocking slide 13 contacting each other, as shown in Fig. 6 shown.

[0062] Furthermore, the electronic additional module 2 is arranged in the lock housing 10, which has the electronic module displacement element 25. The electronic module displacement element 25 is in the embodiment of the Fig. 6 is designed as a displaceable arm which engages with its free end on the blocking slide 13 of the blocking element 12. In the embodiment of the Fig. 6, the additional electronic module 2 is arranged on a movable part of the lock mechanism and transmits or prevents the movement of the lock mechanism via the electronic module displacement element 25 to the blocking slide 13 of the blocking element 12.

[0063] In Fig. 6, the blocking element 12 is arranged in the blocking position, in which the blocking slide 13 with the blocking slide rollers 14 of the blocking element 12 engages behind the lock latch 11 and a movement of the lock latch 11 is blocked. It is important that in Fig. 6 the movement of the lock mechanism (arrow in Fig. 6) by the additional electronic module 2 by means of the coupling of the electronic module displacement element 25 with the blocking slide 13, ie the movement of the lock mechanism is transmitted to the blocking slide 13 by the electronic module displacement element 25.

[0064] In the blocking position of the blocking element 12 in Fig. 6, the blocking slide 13 of the blocking element 12 engages behind the lock latch 11 such that one of the two blocking slide rollers 14 rests against the rear edge of the lock latch 11, with the blocking slide rollers 14 assuming a dead center position with respect to the rear edge of the lock latch 11. This is possible because the directions of movement of the lock latch 11 and the blocking element 12 are perpendicular to one another. Therefore, the lock latch 11 cannot be moved by an external force acting on the lock latch 11, since the force is introduced into the two blocking slide rollers 14 in the dead center position.

[0065] Fig. 7 shows the lock 1 according to the invention with additional electronic module 2 from Fig. 6, where in the Fig. 7 the blocking element 12 is in the release position. It is important that in Fig. 7 the movement of the lock mechanism (arrow in Fig. 7) for moving the blocking element 12 into the release position by the additional electronic module 2 by coupling the electronic module moving element 25 with the blocking slide 13, ie transmitting the movement.

[0066] When the blocking element 12 is in the release position, in which the electronic module blocking element 20 allows the movement of the lock mechanism, the lock latch 11 can be inserted into the lock housing 10. In the release position of the blocking element 12, the blocking slide rollers 14 on the blocking slide 13 do not engage behind the lock latch 11, as shown in Fig. 7, in which the blocking slide rollers 14 in the embodiment of the Fig. 3 have been displaced by the blocking slide 13 from the area of ​​the rear edge of the lock latch 11. Moving the two blocking slide rollers 14 from the dead center position causes the lock latch 11 to be safely released.

[0067] Fig. 8 shows the lock 1 according to the invention with additional electronic module 2 from Fig. 6 and Fig. 7, where in the Fig. 8 the blocking element 12 is in the blocking position, in that the additional electronic module 2 prevents the transmission of the movement of the lock mechanism to the blocking element 12 by displacing the electronic module displacement element 25, i.e., does not transmit the movement of the lock mechanism. To this end, the electronic module displacement element 25 compensates for the movement of the lock mechanism by pushing the electronic module displacement element 25, which is designed as an arm, further out of the housing of the electronic module displacement element 25. This can be done by a drive of the additional electronic module 2, or in that the electronic module displacement element 25 is mounted so as to be freely movable in the additional electronic module 2.

[0068] In this embodiment, the lock latch 11 can be blocked either by allowing the movement of the lock mechanism onto the blocking element 12 ( Fig. 6) or preventing the movement of the lock mechanism onto the blocking element 12 by the electronic module blocking element 20 ( Fig. 8). Release of the lock latch 11 ( Fig. 7) is carried out by allowing the movement of the lock mechanism onto the blocking element 12 for release by the electronic module blocking element 20.
