ABSTRACT:
Disclosed is a unilaterally alternating torque backlash lock mechanism that overcomes the disadvantages of prior art single part loop spring braking parts. The invention comprises a control element having a hub member and a housing member surrounding the hub member. The hub member is equipped with a sleeve curving at a distance around a bearing member (or inner hub member). The sleeve does not completely surround the bearing member, but rather displays a slot-like area running its entire length, thus forming a drive slot. A spring is wound around the bearing member and is so designed that each of the spring ends form a peg-like member bent down radially in the outward direction. Each of these peg-like members abut with some clearance against one of the edges of the slot in the sleeve on one side and against a cam-like member on the other side. The cam-like member is formed on the inside surface of the housing and is of sufficient dimensions to extend into the slot-like area of the sleeve.
