Abstract

The safety crank handle has a housing fixable secure against rotation on the structure side and a hub (5) which can be fixed opposite the housing by a brake device. Between the hub (5) and housing wall is one or more rolling bodies on which an entrainment member (4) is supported during operation of the drive part . The hub is formed in the contact area with the rolling body as a cam disc (6) whose smallest distance from the housing wall is less than the diameter of the rolling body and whose greatest distance from the housing wall is equal to or slightly more than the diameter of the rolling body. The rolling body can be pressed against the cam disc by a compression spring (8) lying in a socket (9) in the hub (5).
