Description

The present invention relates to a lock having at least one locking element and an actuating element, which are in operative connection with each other, wherein the lock is switched by actuating the actuating element to a locked position to an unlocked switching position, when the lock is in an unlocked state, and on the other hand from the unlocked switching position in the locked switching position is switchable and wherein the locking element is in the locked switching position of the lock in a locking position and is in the unlocked switching position of the lock in an unlocked position, and with an actuator through which the lock from the locked state to the unlocked state is switchable when the lock is in the locked switching position, and with a switchable by the actuator blocking device by the de in the locked state s lock a switching of the lock from the locked switching position is prevented in the unlocked switching position.

Locks of this type are used in particular for doors, but in principle can also be used in windows or the like. An essential feature of these locks is that the locking element is not moved as usual by turning a key in a lock cylinder from a locking position to the unlocked position and vice versa, but by operating an actuating element, which may be coupled, for example with a handle. In these locks, the key with the associated lock cylinder serves as an actuator for the blocking device, wherein Turning the key, the lock is reversible from the locked state to the unlocked state and the blocking device in the locked state prevents unlocking of the lock by the actuating element.

In the locks of the type mentioned above, as described above, to open a door with a lock located in the locked position and in the locked state first the lock by turning the key in the unlocked state and then by operating the actuator of the locked switching position be brought into the unlocked switching position, before the door can be opened. The disadvantage of this is that on the one hand the carrying of a key is required and on the other hand, a rotary actuation of the key is connected due to the small lever arm with a relatively large amount of force.

It is an object of the present invention to provide a lock of the type mentioned, which ensures easy operation with a simple design of the castle.

To solve this problem, a lock with the features of claim 1 is provided.

The lock according to the invention is characterized in that the actuator comprises an electric drive unit which is drive-effective, in particular mechanically or magnetically coupled to the blocking device or coupled and controlled by an electronic control device to change the lock from the locked state to the unlocked state.

Due to this design, the lock can be switched by the user from the locked state to the unlocked state by driving the electronic control device, whereby the operation of the lock is considerably simplified. In this case, any device which is designed to transmit a user input to an electrical or electronic control and / or power supply signal for the electric drive unit of the actuator is considered an electronic control device.

Advantageous embodiments of the invention are described in the subclaims, the description and the drawings.

The locking element may advantageously be formed by a locking bolt which is in the locked switching position of the lock in an extended position and is in an unlocked switching position of the castle in a retracted position. As a result, a particularly reliable locking of the lock can be ensured. In principle, however, in the context of the invention, the locking element may also comprise another element which cooperates in the locking position with an element of a door or window frame to prevent opening of the door or the window, and in an unlocked position, an opening of the door or the window allowed. For example, the locking element may have a pivotable hook, which in the locking position can engage in a recess of the frame or form an undercut with an element of the frame, or a pin, in particular a mushroom pin, in the locking position into a U-shaped or shoe-shaped recess the frame can be retracted include.

In the following, the lock located in the locked switch position and in the locked state is also referred to as a "locked and locked" lock. The bringing of the lock in this configuration is accordingly also referred to as "lock and obstruct" the lock. Accordingly, the lock located in the locked switch position and in the unlocked state is referred to as the "locked and unlocked" lock and the lock located in the unlocked switch position is referred to as the "unlocked" lock.

According to an advantageous embodiment, the lock is designed so that the lock located in the unlocked switching position can be brought by actuation of the actuating element simultaneously in the locked switching position and in the locked state. Separate actuation of an actuator or a separate input by the user to lock the lock is thus not necessary, whereby the operation of the lock is additionally facilitated. To lock the unlocked lock and lock at the same time, for example when leaving the house, then only one actuation of the actuator is required so that a particularly simple operation is guaranteed. The required actuation may consist in particular in a rotation of a handle coupled to the actuating element in a predetermined direction of rotation.

According to a preferred embodiment, the actuating element designed, for example, as a pusher nut can be coupled or coupled with a handle. The lock is preferably designed so that it can be switched by turning the handle coupled to the actuator in a first rotational direction of the unlocked switching position in the locked switching position and by turning the handle in one of the first rotational direction opposite second direction of rotation of the locked Switching position can be switched to the unlocked switching position when the lock is in the unlocked state.

Again, the lock is preferably designed so that the unlocked lock not only locks when turning the actuator in the first direction, but is also locked and locked.

Advantageously, the lock comprises at least one latch which is movable from an extended position to a retracted position by rotating the handle coupled to the actuator in the second direction of rotation. By turning the handle in the second direction of rotation, both the lock unlocked and the latch can be retracted, so that the lock can be opened drehge.

Conveniently, the actuator may comprise a pusher comprising a return mechanism which causes the handle to be automatically actuated, e.g. by spring force, is pushed back to its original position when the user no longer exerts force on the actuator. In this case, for example, the latch can be retracted in the usual way only during the operation of the handle and automatically extended when you release the handle.

In the context of the invention, the lock may comprise a plurality of lock traps, which are coupled in the manner described above with the actuating element.

According to an advantageous embodiment, the locking element on one of its outer surfaces on an electrical contact, which is on the one hand electrically connected to the electric drive unit and on the other hand is contactable when located in the locking position locking element from outside the castle. About one or more such contacts can be done in a particularly simple manner, a power supply and / or electrical control of the electric drive unit of a provided outside of the lock control device, namely on the locking element. The contact may protrude at a particular end-side outer surface of the locking element and be connected via an electrical line to the drive unit. In this case, the electrical conductor can extend in particular in a channel extending through the locking element. In the context of the invention, an arrangement of the contact of the lock at another location is conceivable, which is contacted from the outside, ie the lock may have a connected to the electric drive unit - for example, as a contact and / or spring contact formed - electrical contact, the when built into a wing of a window, a door or the like lock from outside the castle is contacted and is electrically contacted with a closed wing, for example by a frame-side mating contact by touching the contact and the mating contact. It can then be dispensed with a complex wiring of the castle from the side of the hinges of the grandfather. In the context of the invention, it is in any case advantageous if the contact of the lock and a corresponding, arranged in the context of the door or the window mating contact are designed so that both contacts with the door closed or closed window at least in the locked switching position of Lock are not accessible, so that manipulation by an intruder is prevented.

The lock may include a transmission member operably coupled to the locking member and the actuator. By the transmission element, a movement of the actuating element can be converted into a corresponding switching of the elements of the lock and in particular of the locking element. For example, a rotational movement of the actuating element can be converted into a linear displacement of the locking element between the locking position and the unlocking position.

The transmission element may comprise a slidably mounted plate in the lock, which has a link and a rack portion, wherein the link with the locking element or an operatively connected part forms a link guide and the rack portion with a gear portion of the actuating element forms a gear transmission.

According to an advantageous embodiment, the blocking device comprises a blocking element, which is in the locked state of the lock in a blocking position and is in the unlocked state of the lock in a release position. The blocking element may in this case be e.g. be mounted linearly displaceable in the castle.

Preferably, the blocking element comprises a coupling portion for the drive-effective, in particular mechanical or magnetic coupling of the blocking element with the actuator and for switching the blocking element from the blocking position to the release position by the actuator.

Advantageously, the transmission element is in the locked switching position of the lock in a locked position and in the unlocked switching position of the lock in an unlocking position, wherein the blocking element in its blocking position an undercut with the forms in the locking position located transmission element which prevents movement of the transmission element from the locking position to the unlocked position. In this way, when the lock is locked and locked, a switchover of the lock from the locked switch position to the unlocked switch position can be prevented in a particularly effective manner.

The lock can advantageously have a particular mechanical actuating mechanism which brings the blocking element in the blocking position when the lock is switched from the unlocked switching position to the locked switching position. The adjusting mechanism thus causes a switching of the lock of the unlocked switching position in the locked switching position simultaneously causes a change of the lock in the locked state, so that the lock can be locked and locked simultaneously by operating the actuator.

For example, the actuating mechanism may include a spring coupled to the blocking element that urges the blocking element into the blocking position.

According to an advantageous embodiment, the lock comprises a holding mechanism with a holding element, wherein the holding element engages with the blocking element during the movement of the blocking element from the blocking position to the release position and holds the blocking element brought into the release position against a tension of the spring in the release position, if the lock is in the locked position. In this way, it is ensured that the blocking element is brought on the one hand by the above-described adjusting mechanism in the blocking position and thus the lock automatically is locked when the lock is switched from the unlocked switch position to the locked switch position. On the other hand, when the lock is locked, the blocking element brought into the release position is held in the release position by the retaining mechanism, so that the lock is effectively unlocked until deliberately locking and locking of the lock by a user.

A transmission element as described above may preferably comprise a portion which forms a stop for the blocking element when the transmission element is between the locking position and the unlocking position, and which releases a movement of the blocking element into the blocking position when the transmission element is brought into the locking position ,

According to an advantageous embodiment, the electric drive unit of the lock comprises at least one electromagnet and a magnetically coupled to the electromagnet body. By driving the electromagnet, the electromagnet and the body are preferably movable relative to one another substantially linearly. For this purpose, the electromagnet and the body can be mounted linearly movable relative to each other. In principle, the electric drive unit of the lock can comprise a linear drive unit, such as a linear motor.

The lock can in this case comprise a deflection device which deflects a movement of the electromagnet or of the body into a movement of the blocking element of the blocking device. The diverter may comprise a diverter pivotally mounted in the lock and including two pivot arms, a pivot arm being drivably coupled to the electromagnet or the body, and the diverter another pivot arm is drivingly coupled to a blocking element of the blocking device. In this way, a linear movement of the body relative to the electromagnet in a first direction can be deflected into a linear movement of the blocking element in a second direction. According to one embodiment, the electromagnet or the body is connected to a particular rod-shaped coupling member which is coupled to the deflecting element. This results in a particularly simple construction of the drive unit.

The electronic control device preferably has an input module which allows a user to input. Here, an authentication of the user is preferably performed by the input module, for example by a number code is queried or read biometric data of the user.

According to an advantageous embodiment, a lock as described above comprises a plurality of locking bars and / or locking elements which are in the locked switching position of the lock in each case in a locking position and are in the unlocked switching position of the lock in each case in an unlocked position. As a result, a particularly effective locking can be effected. Here is particularly the advantage to bear in that for switching the lock of the unlocked in the locked switching position and vice versa, a greater force is available, since the switchover is done via the actuator, which may be coupled, for example with a handle, so that a correspondingly large Lever is available.

Another object of the invention is a door, a window or the like with a wing, built into the wing and as above described lock as well as with a frame. The advantageous embodiments and advantages of the invention described above with respect to the lock apply correspondingly.

According to one embodiment, the frame comprises a recess for receiving the locking element and at least one electrical contact, which is on the one hand connected to the electronic control device and on the other hand designed for contacting an electrical contact provided on the locking element and in particular engages in the recess. In this way, a particularly simple electrical connection between the control device and the drive unit can be provided. As described above, the electrical contact can also be arranged at another point of the lock so that it can be contacted from outside the lock, wherein the counter-contact of the frame is arranged so that it contacts the lock with the window closed, the Touched door or the like and thus produces an electrical contact.

The above-described recess of the frame for receiving the locking element of the lock can e.g. be formed in a strike plate of the frame.

According to one embodiment, the contact of the frame and / or the contact of the locking element are designed as an electrical contact contact and / or as an electrical spring contact. As a result, a reliable electrical contacting of the two contacts can be ensured.

For example, the electronic control device may include a switch, a keyboard, a card reader or a biometric sensor, such as e.g. include a fingerprint sensor or retinal scanner.

Fig. 3

the door of Fig. 1 and 2 with lock located in the unlocked switch position.

Fig. 1 to 3 show a door with a wing 10, a built-in the wing 10 lock 12 and a frame 14. The lock 12 comprises a housing 15, the side cover plate in the Fig. 1 to 3 is not shown to release the view of the present in the housing 15 lock components. For better visibility, individual elements of the lock are 12 in Fig. 1 also shown partially transparent, with more distant contours, which are concealed at for themselves from more distant contours, are represented by thinner lines.

In Fig. 1 the lock 12 is shown in the locked position and in the locked state.

The lock 12 comprises a locking element 16 'designed as a locking bolt 16 and an actuating element 18 designed as a pusher nut, which is in operative connection with the locking bolt 16. The actuator 18 is further drivingly coupled to a latch 20. Lock bolt 16 and lock latch 20 engage in their in Fig. 1 shown extended position in each case in a recess 22 of a introduced into the frame 14 strike plate 23 a.

The actuating element 18 has an opening 25 into which a square pin of a handle for non-rotatable coupling with the actuating element 18 can be inserted.

An opening 25 comprising the coupling part 26 of the actuating element 18 is rotatably mounted in the lock 12 and acted upon by a spring force, that he always in the in Fig. 1 to 3 shown orientation is urged, in which a coupled with the actuator 18 handle extends horizontally to the right.

The locking bar 16 is coupled to the actuating element 18 in such a way that it locks when the lock is released (FIG. Fig. 2 ) by turning the coupling part 26 by about 45 ° in the direction of the arrow 27 from the in Fig. 1 shown extended position in the in Fig. 3 shown retracted position can be brought. A part 30 of the actuating element 18, via which the locking bolt 16 is coupled to the coupling part 26 of the actuating element 18, has a freewheeling relative to the coupling part 26 via the rotational angle range indicated by the arrow 32. The part 30 has a gear segment 34 which meshes with a gear 36. The gear 36 in turn meshes with a rack portion 38 of a transmission element 40, which is designed as in the lock in the direction of the double arrow 42 slidably mounted plate. The transmission element 40 comprises a link 44, in which a corresponding, not visible in the figures pin of the locking bar 16 engages to form together with the link 44 a slotted guide. The slotted guide is designed so that a displacement of the transmission element 40 in the direction of an arrow 46 leads to a displacement of the locking bolt 16 in the direction of an arrow 48, whereby the locking bolt in the in Fig. 3 shown retracted position can be brought.

Switching the fitting into the in Fig. 3 illustrated unlocked switching position by actuating the actuating element 18 is in the in Fig. 1 shown locked state of the lock prevented by the blocking device 50.

The blocking device 50 comprises a blocking element 52, which in the locked state of the lock in the in Fig. 1 is shown blocking position and in the unlocked state of the lock in the in Fig. 2 is shown release position.

The lock 12 further comprises an actuator 54 with an electrically operated drive unit 55, through which the blocking element 52 from the blocking position in the in Fig. 2 shown release position brought and the lock 12 is unlocked. A description of the structure and operation of the actuator 54 follows the description below of the operation of the locking mechanism.

The blocking element 52 is displaceably mounted in the lock 12 in the direction of an arrow 53. In the blocking position, the blocking element 52 prevents movement of the transmission element 40 from the in Fig. 1 shown locking position in the in Fig. 3 illustrated Entriegelposition by actuation of the actuating element 18 and thus switching the lock 12 from the locked to the unlocked switching position.

For this purpose, the blocking element 52 has a blocking section 57 with an outer surface 58 which, with an outer surface 60 of the transmission element 40, extends in the direction of the arrow 46, i. in the direction of movement of the transmission element 40, effective undercut forms.

As described above, the lock assembly is in Fig. 1 to 3 shown in a partially transparent representation, with more distant and thus actually hidden contours are represented by thinner lines. For example, in the direction perpendicular to the plane of the drawing, the blocking element 52 has a plurality of successive planes in which the blocking element 52 each assumes a different cross section, the contours of the blocking element being represented by thinner lines in the rearward planes.

For better recognition of the blocking is in Fig. 1 to 3 in each case a detailed view A shown separately, in which the blocking element 52 is shown in cross section, in the plane in which the blocking portion 57 of the blocking element 52 is located.

The detail view A in Fig. 1 shows that the outer surface 58 of the blocking element 52 in the direction of movement of the transmission element 40 forms an undercut with the outer surface 60 of the transmission element 40. The blocking element 52 is in the direction of the double arrow 59 mounted immovably in the lock 12, so that a movement of the transmission element 40 in the direction of the arrow 46 is effectively blocked. The outer surfaces 58 and 60 extend substantially perpendicular to the direction of the arrow 46, whereby a particularly effective blocking is achieved.

The lock 12 has an actuating mechanism 64 with a spring 66, which is fixed on the one hand to the housing 15 and on the other hand engages the blocking element 52 and in the release position (in Fig. 2 ) located blocking element 52 in the in Fig. 1 shown blocking position urges.

The spring 66 can be designed so that they both in the release position and in the Fig. 1 shown blocking position of the blocking element 52 is under tension and the blocking element 52 urges in the direction of the arrow 68. The blocking element 52 is held against the force of the spring 66 by a holding mechanism 70 in the blocking position. The holding mechanism 70 is at the same time formed to the brought by the actuator 54 in the release position blocking element 52 as in Fig. 2 to be kept in the release position.

The holding mechanism 70 comprises a holding element 72, which is formed as pivotable about an axis of rotation 74 in the lock 12 mounted pivot lever with two pivot arms 76. A pivot arm 76 is loaded with a spring 78, which exerts a rotational force in the direction of the arrow 80 on the retaining element 72. In Fig.1 the holding member 72 is engaged with the blocking member 52 and thus prevents movement of the blocking member 52 in the direction of the arrow 68. In this case, an outer surface 84 of the holding member 72 forms an effective in the direction of the arrow 68 undercut with an outer surface 86 of the blocking member 52. The outer surface 84 defines a projection 88 of the holding member 72 and the outer surface 86 defines a recess 90 of the blocking element 52, in which the projection 88 engages. As in Fig. 1 shown, the two outer surfaces 84, 86 are substantially perpendicular to the direction of the arrow 68th

In addition to the recess 90, which defines the blocking position of the blocking element 52, the blocking element 52 has a further recess 92 which defines the release position of the blocking element 52. When in Fig. 1 the blocking element 52 is displaced by the actuator 54 in the direction of arrow 93 in the release position, the projection 88 engages in the recess 92, wherein the outer surface 84 of the projection 88 an effective in the direction of the arrow 68 undercut with an outer surface 98 of the recess 92nd forms and so the blocking element, as in Fig. 2 shown holding in the release position.

Fig. 2 shows the lock 12 after it has been unlocked by the actuator 54 as described above, ie in the locked and unlocked state.

As in particular the cross section of the detail view A in Fig. 2 shows, located in the release position blocking element 52 forms with the located in the locking position transmission element 40 in the direction of movement of the transmission element 40 effective undercut more and releases a movement of the transmission element 40 in the unlocked position. By turning the actuating element 18 or a handle coupled thereto in the direction of the arrow 27, thus, the lock in the in Fig. 3 shown unlocked switching position are switched, in which the locking bar 16 is in its retracted position.

In the locked and unlocked state according to Fig. 2 holds the holding member 72, the blocking element 52 in the release position. The transmission element 40 has an inclined surface 100, which runs when unlocking the lock 12, ie upon displacement of the transmission element 40 in the unlocking on an inclined surface 102 of the holding member 72 and the holding member 72 pivoted against the spring 78 in the direction of the arrow 103, so that the Retaining element 72 out of engagement with the blocking element 52 passes. The blocking element 52 is then moved in the direction of the arrow 68 by the force of the spring 66 and abuts with an outer surface 104 against an outer surface 106 of the transmission element 40.

If the unlocked lock 12 of Fig. 3 switched by turning the actuator 18 in the direction of arrow 109 back into the locked switching position, the outer surface 106 of the movement path of the blocking element 52, so that the blocking element 52 by the force of the spring 66 automatically returns to the in Fig. 1 shown blocking position returns. This ensures that when switching the lock 12 of the in Fig. 3 illustrated unlocked switching position in the in Fig. 1 shown locked switch position automatically obstructing the lock 12 is done.

In the in Fig. 3 shown unlocked switching position, the holding member 72 is held by an outer surface 108 of the transmission element 40 in a disengaged position in which the projection 88 is located outside of the recesses 90, 92 of the blocking element 52. When the blocking element 52 is brought into the release position via the actuator 54 when the lock 12 is unlocked, the outer surface 108 prevents the retaining element 72 from engaging the blocking element 52.

The actuator 54 comprises an electromagnet 110 and a body 112 slidably mounted relative to the electromagnet 110 in the direction of the double arrow 111 and magnetically coupled to the electromagnet 110. The body 112 may be, for example, a permanent magnet or a magnetizable body, e.g. from a ferromagnetic material, act.

The body 112 is coupled via a rod-shaped coupling member 114 with a pivot arm 116 of a pivoting about an axis 118 rotatably mounted deflecting element 120, wherein a further pivot arm 122 of the deflecting element 120 engages in a recess 124 of the blocking element 52 and thus a movement of the body 112 in the direction of Arrow 125 in a movement of the blocking element 52 in the direction of the arrow 93 deflects. When the solenoid 110 is energized, the body 112 is pulled toward the solenoid 110, thus bringing the blocking member 52 in the blocking position to the release position.

The electromagnet 110 is connected via two electrical lines 126 with two attached to an end face 128 of the locking bolt 16 electrical contacts 130. The electrical lines 126 are guided by corresponding, introduced into the locking bar 16 channels. With the door closed and the lock locked ( Fig. 1 and 2 ), the electrical contacts 130 are contacted by two electrical spring contacts 132. The spring contacts 132 are mounted with a frame side, in Fig. 1 to 3 not shown further connected control device, via which the actuator 54 is controlled. The control device is designed to form a circuit between the electromagnet 110 and an electrical power source, which preferably also on the frame side may be appropriate to selectively close and open depending on a user input to attract the electromagnet 110.

The control device in this case comprises an input unit for a user, via which the user can effect an actuation of the actuator 54 and thus an unlocking of the lock 12. The input unit may comprise, for example, a switch, a button, a keyboard for inputting an access code, a card reader or a biometric sensor. The control device can be embedded in a conventional manner in the frame 14 or a surrounding masonry, that from the outside, only the input unit is accessible.

• In der in Fig. 1 dargestellten verriegelten und versperrten Schlossstellung ist für einen Benutzer keine Entriegelung über das Betätigungselement 18 möglich, ohne dass das Schloss 12 vorher entsperrt wird. Zum Entsperren tätigt ein Benutzer eine entsprechende Eingabe in die Steuereinrichtung, woraufhin der Elektromagnet 110 bestromt und das Blockierelement 52 in die Freigabeposition gebracht wird (Fig. 2). Da das Blockierelement 52, wie in Fig. 2 gezeigt, durch das Halteelement 72 in der Freigabeposition gehalten wird, ist nur eine vorübergehende Bestromung des Elektromagneten notwendig, um das Schloss 12 dauerhaft zu entsperren. Im geschlossenen Zustand des Schlosses sind die elektrischen Kontakte 130, 132 und Leitungen 126 nicht von außen zugänglich, sodass eine Manipulation und ein unbefugtes Entsperren wirksam verhindert werden.

Below is the functional operation of in Fig. 1 to 3 summarized door summarized:

• In the in Fig. 1 shown latched and locked lock position is unlocked for a user via the actuator 18 without the lock 12 is unlocked before. To unlock a user makes a corresponding input to the controller, whereupon the solenoid 110 is energized and the blocking element 52 is brought into the release position ( Fig. 2 ). Since the blocking element 52, as in Fig. 2 is held by the holding member 72 in the release position, only a temporary energization of the electromagnet is necessary to unlock the lock 12 permanently. In the closed state of the lock, the electrical contacts 130, 132 and lines 126 are not accessible from the outside, so that manipulation and unauthorized unlocking are effectively prevented.

The unlocked lock 12 ( Fig. 2 ) can then by turning a coupled to the actuator 18 handle in the direction of arrow 27 in the in Fig. 3 shown unlocked switching position are brought, in which the locking bolt 16 is retracted. In Fig. 3 the unlocked lock 12 is shown after the handle is returned by the return mechanism in its horizontal starting position in which the lock latch 20 is extended. In the unlocked switching position, the handle can always turned back down and thereby the latch 20 are retracted, after which the door can be opened in rotation.

From the in Fig. 3 illustrated unlocked switching position, the lock 12 can be locked by a user by turning the handle in the direction of arrow 109 again. At the same time the blocking element 52 is brought by the spring 66 back into the blocking position, so that the lock is locked and locked by the same handle operation at the same time.

It may be the case that the unlocked door is pivotally opened by a user and then the lock 12 is locked and locked by the user without the door being completely closed. In this case, the contacts 130 of the locking bolt 16 are not in contact with the spring contacts 132 of the frame, so that an energization of the drive unit 55 as described above via the spring contacts 132 for unlocking is not possible. In order to enable unlocking in this case, the lock 12 in addition to the control device may include a mechanical or electrical switching device, via which the lock can also be unlocked if necessary. This switching device can be designed so that it is accessible only from the inside of the door, so that unauthorized access continues to be effectively avoided, which can be unlocked in the rotationally opened state accidentally locked lock 12 but easily. By such a switching device can also be ensured that the house can always be left without further ado, even if, for example, there is a power failure. For this purpose, the lock 12 may also include an emergency battery disposed within the lock 12.

The lock 12 may also include a lock cylinder in addition to the electrically operated actuator 54, as in FIG Fig. 1 to 3 is indicated by a corresponding opening 134, wherein the blocking element 52 has a recess 136, in which engages a pin of the lock cylinder for adjusting the blocking element 52 from the blocking position to the release position or vice versa.
