Abstract
A hinge which provides for a simple and fast assembly or dismantling and for an automated assembly and for use with assumed planarly fashioned hinge pin receptacles which proceed parallel to one another. A region of the hinge is fashioned as an ondular washer or Belleville spring washer in a hinge spring which is inserted between the hinge pin receptacles. The hinge spring is bent arcuately back onto itself over the edge of one of the hinge pin receptacle and is fashioned with catch elements such that these engage into an annular groove of a hinge pin introduced into the aligning bores of the hinge pin receptacles and of the ondular washer or, respectively, Belleville spring washer region.
