Movement transmission device and method

Abstract

The present invention relates to a device and a method, in particular for transmitting a movement as well as corresponding forces or moments and in particular a rotational movement, wherein the transmission only takes place in a coupled state but not in a decoupled state. Devices and methods of this kind are in particular used in the field of lock devices, such as door or safe locks and the like. The device, in particular for transmitting a movement as well as corresponding forces and/or moments comprises a drive and a take-off, wherein the drive and take-off are coupled via a coupling element in such a manner that in the decoupled state a movement of the drive causes a movement of the coupling element which is not suitable for transmitting a movement of the drive to the take-off.
