Description

The invention relates to an electronic unit to be added to a manually operated mortise lock. The invention also relates to a locking system that can be operated manually and electronically.

Locking devices for movable elements such as doors, windows or the like are well known. Simple locking devices, in particular mortise locks, can often only be operated manually. Such locking devices have a latch or a bolt, in particular a hook bolt, which protrudes on the faceplate and which can be retracted via a follower which can be actuated by a trigger. The term “mortise lock” relates very generally to locking devices which are designed to be inserted into a door, in particular into a place at the corner of a door. Mortise locks typically have one or more latches or bolts that can protrude from the lock to engage a stop or some other part of a door frame, window frame, or the like, when the door, window, or the like is closed. The latches or bolts keep the door or window closed and must be pulled back into the locking device to allow the door, window or the like to be opened.

A wide variety of different locking devices, particularly mortise locks, are used in the market. In addition to purely manual locking devices, motorized locking devices or electromechanical locking devices are also known. These locking devices are often operated by an electromagnet that actuates a lever which is mounted on one side of the locking device and to which a pivotably mounted bolt is also attached. When the solenoid is energized, this will hold the lever in its locked and unlocked position.

Purely manually operated locking devices are limited in their operative range. Locking devices that can be operated manually and electromechanically are often very complex and expensive.

The pamphlet U.S. 6,032,500 A discloses a lock with two solenoids, via which locking elements of a lock can be operated.

The pamphlet U.S. 5,790,034 A discloses a lock with a motor by which an actuator of the lock can be operated. When a handle is actuated, transmission elements of a transmission means rub against one another.

The pamphlet EP 1 283 318 A1 discloses a locking device for a door or the like having a leaf with a main lock, with a movably guided drive rod connected to the main lock and a secondary lock, the drive rod having a first position in which the leaf is locked in a frame and has a second position , in which the wing is unlocked with respect to the frame, with an electric drive for the drive rod, with coupling means arranged between the electric drive and the drive rod and with a control device for controlling the electric drive. The drive rod has a mechanical drive for its movement when the electrical drive is switched off, and the coupling means have a free area in which the drive rod can be moved without taking along the electrical drive.

From the pamphlet EP 1 213 425 A1 is a lock with a handle or key-operated main lock, with one of them by means of an additional lock that can be actuated to the rear of the faceplate, and an electric drive for the drive rod that is arranged in a drive housing seated on the faceplate. The electric drive has a reduction gear driven by an electric motor, the last wheel of which engages in a rack section of the drive rod and which has a free-range clutch between the motor and the last wheel, the free-range clutch being assigned to the last wheel. The clearance is a rotational movement play in the last wheel formed by two toothed disks lying one above the other.

It is an object of the present invention to provide an electronic unit which, in a simple and inexpensive manner, extends a purely manually operated mortise lock into a manually and electromechanically operated locking device. Furthermore, a locking system is desired which can easily be switched between a purely manually operated mortise lock and a manually and electromechanically operated locking device. The above-mentioned object is achieved by an electronic unit with all the features of independent claim 1 and by a locking system with the features of claim 12. Advantages, features, details, aspects and effects of the invention emerge from the dependent claims, the description and the Drawings. Features and details that are described in connection with the electronic unit also apply to the locking system, and vice versa.

According to a first aspect of the present invention, the object is achieved by an electronic unit for insertion into a housing of a manually operated mortise lock and / or for replacing an upper or lower cover flap of the manually operated mortise lock with a manually and electronically operated one Provide locking system. The electronic unit has a motor, a gear means which can be actuated by the motor, the gear means being designed to couple the motor to an opening and closing mechanism of the mortise lock and to actuate the latter. Furthermore, connection means for connecting the transmission means of the electronic unit to the opening and closing mechanism and a control device for operating the motor of the electronic unit are provided. The transmission means of the electronic unit is designed such that the motor is decoupled from the opening and closing mechanism during manual actuation of the locking system.

Such an electronic unit enables a purely manually operated mortise lock to be expanded into a manually and electromechanically operated mortise lock in a simple and inexpensive manner. A normally manually operated mechanical mortise lock can be expanded into a manually and electromechanically operated locking system by adding the electronic unit.

The electronic unit can be attached to a normal, manually operated mortise lock. The electronic unit can be attached to a normal, manually operated mortise lock by simple connecting means such as screws or the like. For example, a faceplate connecting screw and a cylinder nut can be loosened and removed. Thereafter, an upper or lower cover flap can be removed from the mortise lock or the locking device body. The electronic unit can be inserted on the lock body at the same position where the cover flap was placed. After the electronic unit has been inserted into the mortise lock, the faceplate connecting screw and the cylinder nut can be reinstalled. In other words, the electronic unit can be upper or lower Replace the cover flap of the manually operated mortise lock. The addition of the electronic unit to the manually operated mortise lock creates a locking system that can be operated both manually and electromechanically.

The transmission means of the electronic unit are operated by a motor or a motor unit. The transmission means are designed to couple the motor to an opening and closing mechanism of the mortise lock and to actuate the opening and closing mechanism of the mortise lock. Therefore, the transmission means can have some transmission elements that interact with one another. The motor is able to move at least one of the transmission elements. This (s) motor-driven gear element (s) transmits / transmit the movement to at least one further gear element, which actuates the opening and closing mechanism of the mortise lock. The connecting means of the electronic unit are designed in such a way that they can connect the transmission means of the electronic unit to the opening and closing mechanism of the mortise lock. In other words, the connecting means can attach one of the gear elements to the opening and closing mechanism of the mortise lock, so that a movement induced by the motor can be transmitted to the opening and closing mechanism of the mortise lock. The motor of the electronic unit is operated by a control device of the electronic unit. The control device can be arranged in the electronic unit, in particular in a housing of the electronic unit. Alternatively, the control device can be an external unit which is placed separately from the electronic unit. The motor and the control device are operated by a power supply. The power supply can be, for example, an electrical current from a power grid or electrical current from a battery.

The transmission means of the electronic unit is designed such that the motor is decoupled from the opening and closing mechanism during manual actuation of the mortise lock. In other words, during manual actuation of the mortise lock, the motor of the mortise lock is released from the transmission means or the transmission mechanism. This means that the motor of the electronic unit is not activated and operated by manual use of the mortise lock. The motor of the mortise lock is not turned while turning the mortise lock with a key or a rotating thumb latch. The addition of the electronic unit in a manual mortise lock increases the functionality of the mortise lock or the locking system. In other words, the addition of the electronic unit to a manually operated mortise lock creates a locking system that can be operated both manually and electromechanically.

After the electronic unit has been inserted into the housing of the manually operated mortise lock and the transmission of the electronic unit has been connected to the opening and closing mechanism of the manually operated mortise lock, a diverse locking system is created.

According to the invention, the transmission means of the electronic unit have a first transmission element which can be actuated by the motor, and a second transmission element which can be connected to the opening and closing mechanism, said transmission elements being designed in such a way that they are at two coupling positions, which are separated by a predetermined distance along the relative movement of the first and second gear members are connectable. Such an electronic unit enables the motor to be decoupled from the opening and closing mechanism during manual actuation of the locking system. During an electromechanical actuation of the electronic unit, the motor moves the first gear element. The first gear element can be coupled to the second gear element at two coupling positions. The first gear element can be moved to the coupling positions by the motor. This can be done directly or indirectly. In other words, the first transmission element can be connected directly to the engine or indirectly to the engine. In the second case, a further gear element, such as a rotor, can be arranged between the first gear element and the second gear element. When the first gear element contacts the second gear element at a first coupling position and is further moved by the motor, the second gear element is moved in a first direction. When the first gear element contacts the second gear element at the second coupling position and is moved further by the motor, the second gear element is moved in a second direction, in particular opposite to the first direction. By moving the second gear element, the opening and closing mechanism of the mortise lock is also moved. A locking element of the locking system, such as a bolt or a latch, can be moved between a locking position and a non-locking position. The control device enables the locking and non-locking of the locking element of the locking system to be controlled without manual actuation of the mortise lock.

The gear elements are designed such that they can be coupled at two coupling positions. The coupling positions are separated by a predetermined distance along relative movement of the first and second gear members. The predetermined distance can be linear or curved, in particular circular.

The transmission means of the electronic unit is designed in such a way that when the first transmission element is not in contact with the second transmission element at a coupling position, the locking system can be operated manually without activating or influencing the motor of the electronic unit. This can be done because, after the locking element has moved, the electronic unit stops the motor and the first gear element is moved to a free position in which it has no contact with the second gear element. In particular, the first gear element is moved into the vicinity of the second gear element. The predetermined distance is equal to or greater than the distance that the opening and closing mechanism of the mortise lock is moved during the movement between the locking and the non-locking positions of the mortise lock. This enables the first gear element to be positioned by the motor in such a way that it does not prevent movement of the second gear element and therefore the movement of the opening and closing mechanism of the mortise lock. During manual actuation of the locking system, the motor is decoupled from the opening and closing mechanism. In other words, during manual actuation of the mortise lock, the motor of the mortise lock is released from the second gear element. This means that the motor of the electronic unit is not activated and is influenced by manual actuation of the mortise lock. The motor of the mortise lock cannot be turned by a key or a rotating thumb latch while the mortise lock is being turned.

An electronic unit can be advantageous by means of which the first gear element of the electronic unit can be rotated or linearly moved relative to the second gear element. The motor can be a rotary motion or a linear motion of the first Cause transmission element. The motor can be a linear motor, for example. Alternatively, the motor can be a rotary motor. If the motor is a linear motor, the first gear element is moved along a linear direction. If the motor is a rotary motor, the first gear element is moved in a circular direction.

According to a preferred further development of the invention, there may be provided an electronic unit which is characterized in that the predetermined distance is equal to or greater than an operating distance of the opening and closing mechanism. This makes it possible that the motor of the electronic unit is not activated and influenced when the mortise lock is used manually. The motor of the mortise lock is not turned while the mortise lock is turned by a key or a rotating thumb latch. To achieve this, the motor moves the first gear element into such a position that the second gear element does not come into contact with the first gear element during a manual movement of the opening and closing mechanism and therefore does not activate the motor.

Adding the electronic unit to a manually operated mortise lock increases the functionality of the mortise lock or the locking system. In other words, the addition of the electronic unit to a manually operated mortise lock creates a locking system that can be operated both manually and electromechanically.

Furthermore, an electronic unit is preferred which is characterized in that the transmission means has a rotor and an activation pin which is fastened to the rotor. The activation pin defines in particular the first gear element. The gear means furthermore has a gear wheel, which in particular defines the second gear element, which is attached to the rotor in a rotatable manner is. The activation pin can be actuated by the motor and the gear wheel can be connected to the opening and closing mechanism. Said activation pin and said gear wheel are designed such that they can be connected at two coupling positions which are separated by a predetermined distance along the relative movement of the activation pin and the gear wheel. The rotor can be operated by the motor of the electronic unit. The activation pin is attached to the rotor. The activation pin is advantageously arranged perpendicular to the axis of rotation of the rotor. The activation pin can be arranged radially to the rotor. The gear wheel is rotatably attached to the rotor. The gear wheel is in operative connection with the opening and closing mechanism. The activation pin can be moved freely between the two coupling positions. The coupling positions are defined as the positions where the activation pin contacts the gear wheel. In other words, the activation pin hits the gear wheel at two points. This means that when the activation pin hits the gear wheel at a first coupling position and is moved further by the motor, the gear wheel is moved in a first direction. The gear wheel moves the opening and closing mechanism of the mortise lock in a first direction. When the activation pin hits the gear wheel at the second coupling position and is moved further by the motor, the gear wheel is moved in a second direction, in particular opposite to the first direction. The opening and closing mechanism of the mortise lock is also moved by moving the gear wheel. Movement of the opening and closing mechanism of the locking system causes the locking element, such as a bolt or a latch, to move between a locking position and a non-locking position.

For example, after the movement of the locking element into a locking position has been carried out, the control device stops the motor and the activation pin is moved into a free position where he has no contact with the second gear element. In particular, the first gear element is moved into the vicinity of the second coupling position. The predetermined distance is equal to or greater than the distance that the opening and closing mechanism of the mortise lock is moved during the movement between the locking position and the non-locking position of the locking element. This enables the first gear element to be positioned by the motor in such a way that it does not prevent movement of the second gear element and thus the movement of the opening and closing mechanism of the mortise lock. During manual actuation of the locking system, the motor is decoupled from the opening and closing mechanism. In other words, during a manual actuation of the mortise lock, the motor of the mortise lock is released from the second gear element. This means that the motor of the electronic unit is not activated and is influenced by manual use of the mortise lock. The motor of the mortise lock cannot be rotated while the mortise lock is being rotated by a key or a rotating thumb latch. Therefore, the motor cannot stop the mortise lock from moving when the locking system is operated manually.

As already stated, it can also be advantageous if an electronic unit is characterized in that the transmission means are designed such that they transfer a linear movement or a rotary movement of the motor into a linear movement of the connecting means.

According to a preferred embodiment of the present invention, it is also possible for the transmission means of the electronic unit to have a transmission rod which is operatively connected to the gear wheel, the connecting means being fixed to said transmission rod. This means that the gear rod is in connection with the gear wheel one side and in connection with the opening and closing mechanism on the other side. The connecting means for fastening the transmission elements to the opening and closing mechanism are advantageously arranged on the transmission rod. A movement of the transmission rod, initiated by the motor, can therefore be transmitted directly to the opening and closing mechanism, in particular a transmission rod or toothed rack, of the mortise lock.

A preferred electronic unit is characterized in that the transmission means has at least two transmission elements and the control device is designed such that it actuates the motor in order to move at least one transmission element, in particular the first transmission element, into a neutral position in order to disengage the motor from the Open and close mechanism to be decoupled. This means that the control device is designed such that it can control the motor in order to bring the first gear element, in particular the activation pin, into a mechanically free or unaffected position. In this position, the movement of the second gear element, in particular the gear wheel, is free. This means that while the opening and closing mechanism and thus the second gear element is moved manually, the first gear element is positioned in such a position that it does not come into contact with the second gear element. Only when the first gear element is actuated by the motor and the first gear element moves in the direction of one of the coupling positions can the first gear element influence the movement of the locking element of the locking system again.

According to a further development of the present invention, the electronic unit is characterized in that a sensor element is provided for determining the actuation of the opening and closing mechanism in order to close the control device enable the motor to decouple from the opening and closing mechanism after said actuation is complete. The sensor element can have one or more sensor elements. The sensor element detects the actuation of the opening and closing mechanism or the locking element. For this purpose, the sensor element is able to enable the control device to decouple the motor from the opening and closing mechanism after said actuation has ended. In other words, when the sensor detects that the opening and closing mechanism and thus the locking element, in particular a bolt or a latch, of the locking system has reached its locking position, a signal is sent to the control device so that the control device can Can control the motor in order to decouple the first gear element, in particular the activation pin, and thereby the motor from the second gear element, in particular the gear wheel, and from the opening and closing mechanism. This enables manual actuation of the opening and closing mechanism of the locking system to have no influence on the motor of the electronic unit. But on the other hand, the opening and closing mechanism can be operated by the electronic unit if desired.

It is also possible that according to the present invention, in one embodiment, the electronic unit is characterized in that the connecting means are designed to provide a form fit and / or force fit between the gear means and the opening and closing mechanism. The connecting means of an inventive electronic unit are advantageously latching means, in particular a connecting spring. This makes it possible to create a simple fastening between the gear elements of the electronic unit and the opening and closing mechanism of the mortise lock after fastening, in particular after insertion, of the electronic unit on or in the locking system. By adding The electronic unit for the mortise lock creates a locking system which can be operated in both ways, purely mechanical and electromechanical.

It can be advantageous if an electronic unit according to the present invention is characterized in that the control device is connected to a power supply. The power supply can be, for example, a power grid or a battery. The activation of the motor by the control device can be done with a cable or wirelessly.

Another aspect of the present invention is a locking system comprising a manually operated mortise lock and an electronic unit with the features according to the first aspect of the invention. Such a locking system makes use of the same advantages as already described above with regard to the inventive electronic unit.

Furthermore, a locking system is preferred, the locking system being characterized in that a locking element is provided in order to be optionally operable by the manually operated mortise lock or the electronic unit. This means that, if necessary, the locking system can be actuated manually by a key or a latch, in particular a handle such as a door handle, or the locking system can be actuated electromechanically by the control device of an electronic unit. The actuation by the electronic unit has the advantage that the locking device can be controlled remotely. In particular, the locking or non-locking of the locking system can be controlled at predetermined times.

A locking system can have one or more locking elements, such as bolts, hook bolts or latch bolts. Furthermore, a locking system can have two or more gear means and two or more opening and closing mechanisms. The two or more transmission means can be operated by one or more motors. The locking system can be any type of locking system. The locking system is advantageously a mortise lock. The mortise lock can be arranged in a door, a window or the like.

Elements with the same function and functionality are in the Figures 1 to 18 provided with the same reference numerals.

Fig. 1 shows a sectional view of an upper part of a locking system 30, which is designed according to the inventive construction principle, wherein the locking element 22 of the locking system 30 is in the locking position. The electronic unit is arranged next to the opening and closing mechanism 21 of the locking device 20. The electronic unit 1 has been added to the manually operated locking device 20 in order to create a diverse locking system 30. For this purpose, the electronic unit 1 is attached to the manually operable locking device 20. In particular, the electronic unit 1 can be inserted into the upper part of the manually operated locking device 20. In order to operationally couple the electronic unit 1 to the manually actuatable locking device 20, the transmission elements 3, 4, 5, 6 of the electronic unit 1 are connected to the opening and closing mechanism 21 of the locking device 20. The connection has been made by connecting means 7 which are attached to a transmission element 6 of the transmission means 3, 4, 5, 6, see Fig. 2 . The connecting means 7 is a spring element which engages with the opening and closing mechanism 21 of the locking device. The opening and closing mechanism 21 also has some gear elements. The opening and closing mechanism 21 is connected to the locking element 22, here in the form of a hook bolt. By moving the opening and closing mechanism 21, the locking element 22 can be moved into a locking position, shown in FIG Fig. 1 , and to a non-locking position shown in FIG Fig. 3 , to be brought. In the locking position of the locking element 22 according to FIG Fig. 1 the gear elements 3, 4, 5, 6 are in a different way from one another arranged than in a non-locking position. This is in the Figures 2 and 4 shown.

The electronic unit 1 is designed to be added to a manually operated locking device 20, in particular a mortise lock, in order to create a manually and electronically operated locking system 30. The electronic unit 1 has a motor 2 and transmission means 3, 4, 5, 6 which can be operated by the motor 2. The transmission means 3, 4, 5, 6 are designed to couple the motor 2 to an opening and closing mechanism 21 of the locking device 20 and to actuate the opening and closing mechanism 21. The connecting means 7 are required for connecting the transmission means 3, 4, 5, 6 of the electronic unit 1 to the opening and closing mechanism 21. A control unit 8 is also provided for operating the motor 2 of the electronic unit 1. The control unit 8 can be arranged inside the electronic unit 1, in particular inside a housing of the electronic unit 1, or can be arranged outside the electronic unit 1. The transmission means 3, 4, 5, 6 are designed such that the motor 2 is decoupled from the opening and closing mechanism 21 during manual actuation of the locking system 30.

Such an electronic unit 1 enables a purely manually operated locking device 20, in particular a mortise lock, to be expanded into a manually and electromechanically operated locking system 30 in a simple and inexpensive manner. This means that a manually operated locking device 20 can be expanded to a manually and electromechanically operated locking system 30 by adding the electronic unit 1.

The transmission means 3, 4, 5, 6 of the electronic unit 1 are designed such that when the first transmission element 4, which is preferably an activation pin, is not in contact with the second transmission element 5, which is preferably a gear wheel, is in a coupling position, the locking system 30 can be operated manually without activating and influencing the motor 2 of the electronic unit 1. The gear elements 3, 4, 5, 6 are designed in such a way that they can be coupled at two coupling positions. The two coupling positions are separated by a predetermined distance 9 along the relative movement of the first and second gear elements 4, 5. The predetermined distance can be linear or circular.

The transmission means 3, 4, 5, 6 of the electronic unit 1 are operated by a motor 2 or a motor unit. The transmission means 3, 4, 5, 6 are designed to couple the motor 2 to an opening and closing mechanism 21 of the locking device 20 and to actuate the opening and closing mechanism 21 of the locking device 20. Therefore, the transmission means 3, 4, 5, 6 can have some transmission elements that interact with one another. The motor 2 is able to move at least one of the transmission elements 4. This motor-driven gear element 4 transmits the movement to at least one further gear element 5, which actuates the opening and closing mechanism 21 of the locking device 20. The connecting means 7 fasten at least one of the transmission means 6 to the opening and closing mechanism 21 of the locking device 20, so that a movement induced by the motor 2 can be transmitted to the opening and closing mechanism 21 of the locking device 20. The motor 2 of the electronic unit 1 is operated by the control unit 8 of the electronic unit 1.

The different positions of the transmission elements 3, 4, 5, 6 of the transmission means of an electronic unit 1 relative to one another are shown in FIGS Figures 5 to 10 disclosed. The transmission means 3, 4, 5, 6 of the electronic unit 1 have a rotor 3 and an activation pin 4 which is fastened to the rotor 3. The activation pin 4 defines the first gear element. The transmission means 3, 4, 5, 6 also have a gear wheel 5, which in particular defines the second transmission element, which is rotatable is mounted on the rotor 3. The activation pin 4 can be actuated by the motor 2 and the gear wheel 5 can be connected to the opening and closing mechanism 21 of the locking device 20. The activation pin 4 and the gear wheel 5 are designed in such a way that they can be connected at two coupling positions which are separated by a predetermined distance 9 along the relative movement of the activation pin 4 and the gear wheel 5. The rotor 3 can be driven by the motor 2 of the electronic unit 1. The activation pin 4 is attached to the rotor 2. In particular, the activation pin 4 is arranged perpendicular to the axis of rotation of the rotor 2. The gear 5 is rotatably mounted on the rotor 3. The gear wheel 5 is in operative connection with the opening and closing mechanism 21. The activation pin 4 can be rotatably moved by the rotor 3. The activation pin 4 can be moved freely between the two coupling positions. The coupling positions are defined as the positions where the activation pin 4 contacts the gear wheel 5. In other words, the activation pin 4 can hit the gear wheel 5 at two points. When the activation pin 5 hits the gear wheel 5 at a first coupling position and is moved further by the motor 2, the gear wheel 5 is moved in a first direction. In Fig. 5 the activation pin 4 is not in contact with the gear wheel 5. In Fig. 6 the activation pin 4 is rotated further and hits the gear wheel 5 at a first coupling position. If the activation pin 4 is moved further, the gear wheel 5 moves the gear rod 6 and thereby the opening and closing mechanism 21 of the locking device 20. This is in FIG Fig. 7 shown. In Fig. 8 the movement of the opening and closing mechanism 21 of the locking device 20 and thus the movement of the locking element 22 of the locking device 20 is complete.

A sensor unit, which is not shown in the figures, is provided for measuring the actuation of the opening and closing mechanism 21 or the movement of the locking element 22 in order to enable the control unit 8 to activate the motor 2 of the opening and closing mechanism 21, after said actuation has ended, to be decoupled, in other words after the movement of the locking element 22 of the locking device 20 has been completed. The sensor unit detects that the opening and closing mechanism 21 and thus the locking element 22, in particular a hook bolt or a latch, of the locking system 30 has reached the locking position. The sensor unit then sends a signal to the control unit 8, so that the control unit 8 can control the motor 2 to decouple the activation pin 4 and the motor 2 from the gear wheel 5 and thereby from the opening and closing mechanism 21. This is in FIG Figures 9 and 10 shown. This enables manual actuation of the opening and closing mechanism 21 of the locking system 30 to have no influence and no effect on the motor 2 of the electronic unit 1.

Fig. 11 shows schematically an electronic unit 1 which is designed according to the construction principle according to the invention. In the Figures 12 and 13 is the electronic unit according to Fig. 11 inserted into the locking device 20 to create a locking system 30.

The Figures 14 to 15 schematically show side views of a locking system 30 according to the invention.

In Fig. 16 the transmission rod 6 of the transmission means of the electronic unit 1 is shown at the beginning of the attachment to the opening and closing mechanism 21 of the locking device 20. Fig. 17 discloses the transmission rod 6 of the transmission means of the electronic unit 1 according to FIG Fig. 16 during the attachment to the opening and closing mechanism 21 of the locking device 20. The connecting means 7, here in the form of a latching element, are arranged on the gear rod 6 of the gear means. The locking element 7 slides on a counter-locking means 10 of the opening and closing mechanism 21 and is thereby pushed back by the counter-locking element 10. At the end of the fastening, the locking element 7 snaps behind the counter-locking element 10 around the gear rod 6 to fix the transmission means to the opening and closing mechanism 21.

Fig. 18 shows schematically an enlarged illustration of some transmission elements 3, 4, 5 of the transmission means of an electronic unit 1. Furthermore, FIG Fig. 18 the defined distance 9 is shown which the activation pin 4 must cover between the two coupling positions. The coupling positions are the places where the activation pin 4 meets the gear wheel 5. The predetermined distance 9 is equal to or greater than the distance which the opening and closing mechanism 21 must cover when it is moved between its two end positions.
