Abstract
Retraction device for lock cranks, essentially characterized by the arrangement coupled to the internal face of the shield and around the penetration hole of the neck of the crank, of a spring in the form of a spiral, with its winding or turns located in the same plane, on the surface of the shield, in which there are, next to the spring, two projections with threaded holes placed on opposite sides of the shield, in such a way that the bent outer end of said spring, is placed abutting on one of said projections, in which is screwed a bridge plate that holds the end of the spring preventing it from leaving its housing, said spring also having its other inner end, with a fold at right angles, which allows it to engage in the hole of a circular ring located on the spring, provided with two limiting teeth of a recess made in its outer edge, these teeth serving to limit the rotation of the circular ring when the actuate it crank, said ring pulls the spring and rolls it back then to its primitive position by the distension force of the spring, once the crank is released.
