Description

The invention relates on the one hand to an electromechanical closure device comprising a lock unit with a hand-operated displacement device for displacing a lock bolt element of the lock unit into an open position, with a blocking device for blocking the lock bolt element, with a blocking element for locking or unlocking the blocking device and with a motor unit, by means of which the blocking element can be moved from a locked position into an unlocking position, wherein the blocking device is displaceable in the unlocked position of the blocking element such that the lock bolt element can be displaced into an open position by actuating the manually operable displacement device and the electromechanical closure device can thereby be opened.

On the other hand, the invention relates to a safe with a safe housing and with a safe door for closing a vault chamber.

Moreover, the invention relates to a method for actuating an electromechanical locking device comprising a lock unit, in which a lock bolt element of the lock unit can be displaced by means of a manual override, if previously a locking element for locking a blocking device for blocking the lock bolt element from a locked position and into a lock position Unlocking position was moved into, so that then the unlocked blocking device opposite the locking element can be moved so that the lock bolt element is displaced in this case in an open position.

Generic electromechanical closure devices are already well known from the prior art and are widely used. A special field of use of such electromechanical closure devices is the provision of safes for the safe closing of safe doors.

It is an object of the present invention to improve the reliability of generic electromechanical closure devices constructive.

The object of the invention is an electromechanical closure device comprising a lock unit with a hand-operated displacement device for displacing a lock bolt element of the lock unit in an open position, with a blocking device for blocking the lock bolt element, with a blocking element for locking or unlocking the blocking device and with a motor unit, by means of which the blocking element is movable from a blocking position into an unlocking position, wherein the blocking device is displaceable in the unlocking position of the blocking element such that the lockbar element can be displaced into an open position by actuating the manual actuating device and the electromechanical closure device can be opened thereby, and wherein the electromechanical closure device according to the invention by a shift of the lock bolt element in the Öffenposition operable Rückstelleinri has to reset the locking element in the locking position, wherein the restoring means comprises a lock bolt element side return element to interact directly with an actuating surface of the locking element.

Thus, upon a displacement of the lock bolt element into a closed position, the lock bolt element is immediately blocked for a new displacement into the open position.

Advantageously, by such independent pre-locking of the blocking device alone due to the force applied by muscle locking element when moving the lock bolt element in the Öffenstellung into the reliability of the present electromechanical locking device to constructively conceivable simple Way significantly improved because the open lock unit or the opened electromechanical shutter device is already locked or pre-locked by the process of opening alone.

Thus, when closing the electromechanical closure device, the blocking element blocking the lock bolt element is immediately blocked by the blocking element, without requiring the motor unit to be activated, as is the case in conventional electromechanical closure devices originally. In this respect, the present electromechanical closure device can be reliably locked without power.

The term "electromechanical closure device" essentially covers all locks, which comprise an at least partially motor-driven lock unit. At least the lock unit is advantageously integrated in a housing of the electromechanical closure device. Preferably, the present electromechanical locking device comprises an authentication device, such as a keypad comprising a keypad, for driving a drive motor to drive components or subassemblies of the lock unit before further key components or subassemblies of the lock unit can be manually operated thereafter, around the electromechanical lock device especially to be able to open manually.

By "manually operable displacement means" are meant components or groups of components of the electromechanical locking device which comprise, for example, a door handle and related actuators for manually actuating the latch member.

The "lock bolt element" engages for closing the electromechanical closure device in a receptacle of a door frame, a door frame, a safe housing or the like. When the electromechanical closure device is opened, the lock bolt element moves out of this receptacle. In this case, it usually moves completely into the housing of the electromechanical closure device or projects only negligibly over this housing. In this respect, the lock bolt element in the present case is preferably associated with the electromechanical closure device and accordingly integrated in its housing.

The term "blocking device" in the context of the invention includes any means of a lock unit whose movement on the one hand by means of a locking element, preferably a motor-driven locking element, locked and by means of which on the other hand, an unauthorized displacement of a lock bolt element can be blocked in an open position. Preferably, the blocking device is spring biased so that it inherits a predetermined direction of movement. The blocking device can be moved translationally and preferably rotationally. In this respect, the present blocking device is ideally a rotatably mounted safety lever.

For the purposes of the invention, the term "blocking element" describes a device by means of which a movement of the blocking device can be prevented if a displacement of the lock bolt element is not desired. The blocking element is presently drivable by means of the motor unit, wherein the motor unit essentially comprises an electrically operated actuator. Preferably, this actuator is equipped with an output shaft on which the blocking element sits.

The object of the invention is also achieved by a method for actuating a lock unit comprising electromechanical locking device in which a lock bolt element of the lock unit can be displaced by means of a manual override, if previously a blocking element for locking a blocking device for blocking the lock bolt element from a locked position and has been moved into an unlocking position, so that subsequently the unlocked blocking device can be displaced relative to the blocking element such that the lock bolt element is displaced into an open position, wherein the blocking element returns to the blocking position by displacing the lock bolt element into the open position or at least in a preloaded Vorsperrposition, from which the locking element wied automatically when moving the blocking device in its blocking position he moves to the locked position, is moved into it.

By the present advantageous method of operation, the reliability is significantly increased at a correspondingly operating electromechanical locking device. Preferably, the blocking device is displaced by means of the lock bolt element when it is displaced into the open position by means of the manually operable displacement device.

Furthermore, the blocking element is preferably moved by motor out of its blocking position.

The present electromechanical closure device can thus be structurally further advantageously simplified when the restoring device comprises a lock bolt element-side restoring element for an actuating surface of the locking element.

A reliable cooperation between the restoring device and the blocking element can be configured particularly advantageous if the restoring device has a return surface corresponding to the blocking element.

In this context, it is particularly advantageous if the actuating surface associated with the blocking element and the restoring surface associated with the restoring device are geometrically advantageously matched to one another. As a result, a particularly low-friction interaction between the components can be achieved.

The latter can structurally advantageously already be designed by the restoring device comprises a ramp to change the actuating surface by sliding on the ramp in their position.

By way of example, such a ramp advantageously forms on the upper side a straight, substantially non-curved restoring surface, while it is curved substantially concavely on a side facing the blocking element.

The corresponding locking element-side actuating surface is advantageously at least partially convex. The curvature of the actuating surface extends in this case advantageously in the direction of displacement of the lock bolt element. In this respect, the restoring surface and the actuating surface can harmonize particularly well with each other. Advantageously, the blocking element-side actuating surface also extends in the longitudinal extent of the blocking element, wherein the longitudinal extension of the blocking element extends in the direction of the axis of rotation.

In this respect, the locking element-side actuating surface is formed axially longer, ie in the longitudinal extension of the blocking element, longer than radially, as in particular in the illustration according to the FIG. 4 is clearly recognizable.

A structurally particularly simple design variant further provides that the lock bolt element comprises the return device, which advantageously dispenses with additional components for realizing the present restoring device, or at least their number can be advantageously reduced.

In this respect, it is advantageous if the restoring device is arranged at a distance from the motor unit. In this respect, it is clear that the present restoring device is ideally not the motor unit or motor-driven components thereof.

If the restoring device has an actuation direction which is substantially aligned with an axis of rotation of the blocking element, the blocking element assigned to an engine output shaft of the motor unit can be actuated particularly compactly by the restoring device without the need for additional gear elements or the like.

In this respect, it is also advantageous if the change in position of the actuating surface represents a rotation about an axis of rotation of the blocking element, wherein the axis of rotation is substantially aligned with an actuating direction of the restoring device.

In this case, advantageously, a translational movement of the restoring device or of the lock bolt element is converted into a rotational movement of the blocking element.

Overall, an interaction between the blocking device, the blocking element and the return device can be advantageously accomplished if the locking element on the one hand has a locking lever for blocking a movement of the blocking device and on the other hand, an actuating lever for corresponding with the restoring device, wherein the locking lever and the actuating lever are spaced from each other on the locking elements.

The actuating lever designed here from the previously described locking element side actuating surface.

The locking lever and the actuating lever can protrude substantially at right angles from the cylindrical base body of the locking element and thus also from the axis of rotation of the locking element or the motor shaft, so that an interaction with the restoring device or with the blocking device can be achieved structurally simple.

Preferably, the actuating lever still has one of the restoring device facing casserole, which is preferably arranged substantially parallel to the return surface, as long as the locking element is arranged in the unlocked position.

The present electromechanical closure device can particularly advantageously further develop bolt works of safekeeping containers. In this respect, the invention also relates to such safes of any kind.

According to a further aspect, the object of the invention is thus in particular also solved by a safe with a safe housing and with a safe door for closing a vault chamber in the safe housing, wherein the safe is characterized by an electromechanical closure device according to one of the features described herein. In this respect, the vault by means of the present electromechanical closure device can also be reliably locked again in a reliable manner, whereby the security at the vault is substantially increased.

Further advantages, objects and features of the present invention will be explained with reference to the appended drawing and the following description, in which an example of an electromechanical closure device according to the invention is shown and described. In the drawing show:

FIG. 6

schematically a further detail view of the restoring device and the locking element of the FIGS. 1 to 5 in a locked position.

In the in the FIGS. 1 to 6 shown electromechanical lock device 1 is an electromechanical lock 2 of a safe not shown here 3. This electromechanical lock 2 comprises a two-part housing 4 with a top 5 and a bottom 6, in which a lock unit 7 is housed.

The lock unit 7 essentially comprises a hand-operated displacement device 8 for displacing a lock bolt element 9 of the lock unit 7 into an open position 10 (see in particular FIG FIG. 5 ).

With regard to the manually operable displacement device 8, only a rotary bushing 11 located in the housing 4 is shown here, in the multi-tooth receptacle 12 of which a correspondingly configured bolt (not shown) of a gripping element, also not shown, can be inserted for manual actuation. Instead of such Gripping element could also be provided with a keypad equipped control unit or the like.

The rotary bushing 11 is in this case mounted or held at least by means of a switching spring element 13 in an inner backdrop 14 of the housing 4 which is not further described here. The rotary bushing 11 has a lever arm element 15 with a pin element 16 arranged thereon, by means of which it is in operative contact with the lock bolt element 9. The rotary bushing 11 is rotatably mounted in the housing 4 about a rotation axis 17.

The lock bolt element 9 protrudes with a body end 18 out of the housing 4 when it is in a closed position 19 and the electromechanical lock 2 is closed (see Figures 2 . 3 . 4 and 5 ). In the Öffenposition 10, the body end 18 is located substantially within the housing 4. At its other body end 18 opposite the body end 20, the lock bolt member 9 corresponds via a Kragarmkontur 21 with the rotary bushing 11, as described above.

The lock unit 7 further comprises a blocking device 25 by means of which the displacement of the lock bolt element 9 into the open position 10 can be prevented. The blocking device 25 is rotatably mounted in the housing 4 about a rotation axis 26 and it is placed between the bottom 6 of the housing 4 and the lock bolt element 9. The blocking device 25 is biased by means of a spring element 27, wherein the bias achieved thereby promotes a rotational movement of the blocking device 25 in the clockwise direction.

While the lock bolt element 9 on the side 28 of its further body end 20 by means of the Kragarmkontur 21 corresponds to the rotary bushing 11, it is on the side 28 of the other body end 20 by means of a further radially adjacent the Kragarmkontur 21 Kragarmkontur 29 with the blocking device 25 in contact, wherein the further Kragarmkontur 29 has an angled at right angles nose 30, which can engage in a blocking device side groove 31.

The lock unit 7 also includes a locking element 35 for locking the blocking device 25, which by means of a motor unit 36 from a locking position 37 (please refer FIG. 6 ) into an unlocking position 38 (see FIG. 5 ) can be moved into it.

In this respect, the motor shaft 39 is at the same time the axis of rotation of the locking element 35. The locking element 35 is also at least supportably latched by means of a compression spring 40 mounted ball member 41 in particular in the locking position 37 and the unlocked position 38 , For this purpose, a triangular-shaped latching unit 42 with a first detent surface side 43 and a second detent surface side 44 is integrally formed on the blocking element 35, wherein the blocking element 35 penetrates the triangular detent unit 42, as well from the illustration in FIG FIG. 6 can be recognized. The representation according to the FIG. 6 shows a perspective detail view in particular on the blocking element 35 seen approximately from the direction of the axis of rotation 26.

According to the invention, the lock unit 7 furthermore comprises a restoring device 45 which can be actuated by displacing the lock bolt element 9 into the open position 10 in order to return the locking element 35 to the blocking position 37, so that when the lock bolt element 9 is moved into the closed position 19 the lock bolt element 9 is displaced again is blocked immediately in the Öffenposition 10, whereby increased reliability with respect to the present electromechanical closure device 1 is achieved.

The restoring device 45 advantageously comprises a lock bolt element-side restoring element 46 for an actuating surface 47 of the locking element 35. The restoring device 45 has a ramp 48 in the region of the restoring element 46, which provides a restoring surface 49 corresponding to the locking element 35, the restoring surface 49 being on the upper side 50 of FIG Resetting element 46 substantially straight and on the blocking element 35 facing side 51 (see FIG. 6 ) is at least partially concave. As a result, the blocking element 35 with its actuating surface 47 can advantageously slide along the return surface 49. In this case, the actuating surface 47 has areas (not explicitly numbered) on the side 52 facing the reset surface 49 that are at least convex.

Since the restoring device 45 structurally particularly outstanding in this embodiment of the further Kragarmkontur 29 is configured, the lock bolt element 9 immediately includes the restoring device 45. Insofar, the restoring device 45 also has an actuating direction 55, which with an axis of rotation 39 of the locking element 35 and Motor unit 36 is substantially aligned. As a result, the restoring device 45 additionally builds particularly easily.

A further advantageous specification of the present invention provides that the blocking element 35, on the one hand, has a blocking lever 56 for blocking a movement of the blocking device 25 and, on the other hand, an actuating lever 57 for corresponding to the restoring device 45, wherein the blocking lever 56 and the actuating lever 57 are spaced from one another Locking elements 35 are arranged. The locking lever 56 and the actuating lever 57 are in this case substantially perpendicular from the cylindrical base body 58 of the locking element 35 and thus also from the axis of rotation of the locking element 35 and the motor shaft 39 from.

The actuating lever 57 still has one of the restoring device 45 facing casserole plane 59 (see FIG. 4 ), which is preferably arranged substantially parallel to the return surface 49 when the blocking element 35 is in the unlocking position 38.

The top and bottom 5 and 6 of the housing 4 can be screwed by means of a screw 70 in a known together.

Advantageously, the electromechanical closure device 1 according to the invention is distinguished by an extraordinarily important additional function, which will be explained again clearly in the following by way of example with reference to the present exemplary embodiment. The fundamental innovation consists of the restoring device 45 and the new advantageous correspondence possibility with the correspondingly designed blocking element 35 via the restoring surface 49 and the actuating surface 47.

Previously, it was necessary, after a lock closure - closed position 19 - in connection with a previous lock opening - Öffenposition 10 - to move the blocking element 35 by means of a motor pulse in the blocking position 37. By means of the lock bolt element-side restoring device 45 according to the invention, the blocking element 35 are automatically returned to the locked position 37 after the lock is fully opened.

Starting from a closed lock 2 (see for example FIG. 2 ), the blocking element 35 is transferred by a motor pulse of the motor unit 36 in the unlocking position 38 in order to open the lock 2 can. Now an operator can turn the rotary bushing 11 counterclockwise from a safe outside by means of the manually operated gripping element and the bolt in communication with the rotary bush 11. By the pin member 16, this rotational movement is converted into a translational movement according to the actuation direction 55. If, as a result, the lock bolt element 9 now moves in the direction of the motor unit 36, the lug 30 releases the blocking device 25. The biased by the spring member 27 blocking device 25 rotates about the rotation axis 26 provided in the housing 26 in a clockwise direction. Since the blocking element 35 has previously been twisted into the unlocking position 38, the blocking device 25 can execute its maximum rotational movement and in this case unlocks the lock bolt element 9 completely. In the course of the further opening operation, the lock bolt element-side restoring device 45 moves in the direction of the locking element 35 (see also FIG. 5 ). As soon as the restoring surface 49 and the actuating surface 47 touch, the blocking element 35 is automatically rotated in the direction of the blocking position 37 about its axis of rotation 39 according to the locking direction of rotation 39A (see FIG FIG. 6 ). If the opening process has been completely completed, the locking element 35 remains in its locked position 37 or in a pre-locked position due to its new geometry already described above (see latching unit 42), the compression spring 40 and the ball element 41. If the lock 2 is closed again, the blocking device 25 shifts back into its blocking position 60 (see, for example FIG. 2 ). As a result, the blocking element 35 completely engage in the blocking position 37, if this has not been done before.

In this respect, the electromechanical closure device 1 or the electromechanical lock 2 has automatically mechanically locked by the actual lock opening.

It goes without saying that the exemplary embodiment explained above is only a first embodiment of the electromechanical closure device 1 according to the invention. In this respect, the embodiment of the invention is not limited to this embodiment.

All disclosed in the application documents features are claimed as essential to the invention, provided they are new individually or in combination over the prior art.
