Abstract

Elastic retention device, especially designed to determine the elastic retention of doors and analogous elements in the closing position, characterized by being basically constituted by two pieces of stamped metal plate and generally approximately parallelepipedic shape, which fit one into another and remain in disposition to make certain relative movements, conveniently guided and limited; the first of whose pieces is open on its back face, in which it has perforated projecting coplanar lugs, through which the fixing of the assembly is carried out to the surface of interest, and also by its upper face or base, in which it has two flat, parallel and facing lugs, arranged in extension of the side walls and provided with rigid vertical holes facing each other; while the second integral part of the assembly, which fits inside the first, is open on its front and bottom faces and has at the bottom edge of its rear wall at least one protruding coplanar stem, which fits into a corresponding hole provided at the base of the first piece, and is provided with two flat, parallel and facing lugs, arranged in extension of the lateral walls and protruding from the upper base, which are crossed by the axis of a roller of crazy rotation, intended to act as a latch, which also passes through the elongated holes provided in the lugs of the first piece; all in such a way that the second piece can move between limits with respect to the first, being constantly driven to adopt a position, corresponding to the closing position of the roller or latch, by the expansive action developed by a helical spring conveniently housed between both pieces .
