Rotary safety set=up for rotatable component - has detention part with abutting surface allowing handle to move in priority direction

摘要

A torsional safety arrangement is for a rotatable component that is to be displaced by one revolution in a priority direction of rotation by a detachable handle. A sprung detention part (15) is mounted on a fixed component part (1) indicating the position of the rotatable component (23). The detention part (15) can engage a retention opening (11) on the rotatable component (23). The opening (11) is assigned to a predetermined position of the latter (23). The handle (12) has a first contact surface (19) that can be set against the detention part (15) to bring it from a stop position to another position releasing the rotary movement (arrow 8) of the rotatable component (23). The detention part (15) has an abutting surface (17) inclined towards the handle (12). The latter (12) has a second contact surface (20) opposite the abutting surface (17) in the stop position.
