Elemento de accionamiento para una cerradura de caja
A door handle for actuating a mortise lock of a door with an output shaft and a handle facing away from the door. The output shaft and the handle have a common rotation axis and are connected to one another via an electromechanical clutch. The output shaft has a recess, on the side facing the handle, dimensioned for a coupling element that is axially displaceable between open and closed positions with a motor, while the handle has a receptacle dimensioned to accommodate the coupling element opposite to the recess. The door handle is particularly reliable when the motor drives a coupling (auxiliary) shaft on which and/or in which at least one coil spring is disposed non-rotatably and coaxially with respect to the stator of the motor. The auxiliary shaft has at least one protrusion engaging in an intermediate space between two neighbored windings of the coil spring to displace the coil spring axially as a result of rotation of the auxiliary shaft. The coil spring engages with the coupling element to at least preload the coupling element, as a result of the axial displacement of the coil spring, in a direction corresponding to such displacement.
