The electrically schaltba re locking device 11 has a housing with a mechanical locking element 33 , z. B. door opener latch 33 . When the door is closed behind, the door opener latch mounted in the housing engages the lock latch stored in the locking device. When the door opener latch 33 is locked, the door cannot be opened. The door opener latch 33 is blocked in this locking position.

To unlock the door opener latch 33 is released. This is done with the interposition of a mechanical transmission 32 by the electrically controllable trigger element 31 . When the door opener latch 33 is unlocked, the door can be accessed by actuating the normal door lock. As a trigger element 31 , a piezo element 31 is provided, which is characterized by its low current consumption me. The gear 32 serves for the suitable implementation of the force effect of the piezo element 31 . In alternative embodiments of the invention, however, the conventionally used electromagnets or electric motors can also be used as a trigger element 31 .

Fig. 3 shows an embodiment of an electrically switchable locking device 1 according to the invention with a piezo bending transducer 31 as a triggering element. A section of the frame A is shown with the electrically switchable locking device 11 mounted therein. This interacts with the bolt 41 of the latch 4 located in the door leaf B. The latch 41 is designed as a spring catch. The assembled locking device 11 has a Ge housing of cuboid shape, in which a piezo-bending transducer as a trigger element 31 and several lever-like cooperating transmission elements are added. The transmission elements are the locking device 33 having a locking bar, the locking bar being rotatably mounted about an axis 33 a. The retaining bar 33 is formed as a two-armed Kipphe bel with the lever arms 33 b and 33 c. The lever arm 33 b cooperates with two slidably mounted pairs of cylindrical rollers 32 a, b and 32 c, d, which form a gear for translating the shorter travel of the piezo bending transducer to the long travel of the rocker arm. The pairs of cylindrical rollers are each acted upon by a spring 34 , 35 and are each positively guided in a cage (not shown). Apart from the executives in the cage, only rolling friction occurs, which means that the device can be designed with very little friction. The two roles of the pairs of roles 32 a, b and 32 c, d are each arranged transversely to their Ver sliding direction side by side. The spring 34 , 35 assigned to the respective pair of rollers 32 a, b and 32 c, d acts along the direction of displacement. The first pair of rollers 32 with the rollers 32 a and 32 b is slidably mounted in the housing in a direction perpendicular to the direction of movement of the lever arm 33 b, ie in the longitudinal direction of the housing, and the second pair 32 with the rollers 32 c and 32 d in a direction perpendicular to first pair 32 a, 32 b in the transverse direction of the housing.

The control and / or control of the piezo bending transducer is carried out with the electrical actuating device which has a data interface 21 , a micro processor 22 , a driver circuit 23 and a monitoring device 25 .

When the piezo bending transducer 31 is in a controlled state, the door is locked. The cylindrical roller pairs 32 a, b and 32 c, d are then in the position shown with solid lines. As a result, the holding bolt 33 is also held in the position shown with solid lines, wherein it engages behind the bolt 41 of the lock latch 4 and prevents the door from opening. A pivoting back of the locking bar 33 in the open position 33 '(shown in dashed lines) is prevented by the first pair of cylindrical rollers 32 a, b. This pair is axially movable in the housing and is urged by the spring 35 in the loading path of the retaining bolt 33 . This first pair of cylindrical rollers 32 a, b is itself prevented from evasive movement by the second pair of cylindrical rollers 32 c, d in the locking state shown. This second pair 32 c, d is acted upon by the spring 34 and is movably mounted in the transverse direction of the housing. The second pair of cylindrical rollers 32 c, d is firmly connected to a locking element, not shown in FIG. 3, so that when the locking element is blocked by the piezo bending transducer, the pair of cylindrical rollers 32 c, d is also blocked. In the locked state, i.e. when e.g. For example, the nose of the piezo bending transducer 31 engages in a groove of the locking element, the door can also be violent sam not open as an opening movement of the retaining key 33 via the interaction of the cylindrical rollers a, b 32, c, d is prevented.

Only with appropriate control does the piezo-bending transducer 31 pivot back into its rest position shown and thus releases the locking element, as well as the cylinder pairs 32 a, b, c, d. If the door is unlocked after the unlocking, a force acts on the first pair of cylindrical rollers 32 a, b via the lever arm 33 b of the holding bolt 33 . The lever arm 33 b is designed as an inclined plane with a small inclination angle of about 2 to 3 degrees. As a result, the pair of rollers 32 a, b is pushed back against the action of the spring 35 . Since the axis of the roller 32 d is offset relative to the axis of the roller 32 a so that a wedge angle of approximately 2 degrees again results here, the movement of the roller pair 32 a, b also displaces the second roller pair 32 c, d the action of the spring 34 in the position 32 a ', b', c ', d'. The retaining bar can now pivot into its open position 33 'and the door can be accessed.

Since the overall reduction ratio of the device is very large, the design must be very low-friction. This is accomplished by the use of the aufeinan the rolling cylindrical rollers 32, a b, c, d, preferably steel rollers ensured. As a further advantage of using rollers 32 a, b, c, d, the device can be made very compact. In alternative embodiments, single rollers or pairs of more than two rollers can also be used instead of the roller pairs 32 a, b and 32 c, d.

Door opener latch 33 , piezo element 31 and gear 32 are designed such that the electrically switchable locking device 11 also opens under preload.

The devices of the locking device 1 according to the invention can be designed in different versions, adapted to the corresponding operating conditions. So z. B. waterproof versions for outdoor use and normal versions for indoor use.
