Arrangement for changing actuating element between positions has spindle emanating from rotary element connecting actuating element holder to rotary element to execute lifting movement limited by stop

摘要

The arrangement has a spindle (22) emanating from a rotary element (12) connecting an actuating element holder (18) to the rotary element. Turning the rotary element in a first direction moves the holder towards it to execute a lifting movement limited by a stop (24). Further movement in this direction moves the holder with the rotary element. Turning in the opposite direction moves the holder away from the stop to decouple the lifting movement.
