Abstract

Any two elements which are to be hinged together and biased to one end position can utilize this assembly if the two mating parts can be either integrally formed with or attached to the elements. The mating parts are formed so that one can be inserted into the other by a sliding action. At least one mating part has a recess in the center into which, after mating, a relatively simple torsion spring is inserted. The direction of the spring insertion is normal to the direction of the sliding action. The arrow in the figure in- dicates the direction in which the spring biases the clip.

SIMPLIFIED BIASED HINGEASSEMBLY

By George Selinko

   Any two elements which are to be hinged together and biased to one end position can utilize this assembly if the two mating parts can be either integrally formed with or attached to the elements. The mating parts are formed so that one can be inserted into the other by a sliding action. At least one mating part has a recess in the center into which, after mating, a relatively simple torsion spring is inserted. The direction of the spring insertion is normal to the direction of the sliding action. The arrow in the figure in- dicates the direction in which the spring biases the clip.

A hairpin loop in the center of the spring snaps into a notch in a small molded projection on one of theelements, thus preventing the spring from being removed unintentionally.
