Pivoting support device, or hinge with a counterbalance spring and fitted to the lateral side of a cover or lid.

摘要

The device consists of a mobile part (1) coupled to a lateral skirt (50) on the cover (5), and a fixed part (30, 31) comprising a head (31) and a lug (30) mounted on the container which is to be covered by the cover (5). The mobile part (1) in the form of a flange comprises a central projection (12) with an enlarged end (18) which, after passing through a hole (51) in the skirt (50), enters a hollow bearing (35) in the fixed part (31). The cylindrical central projection (12) has a diametral slit (19) enabling its enlarged end (18) to pass through the bearing (35). When it emerges from the side opposite the bearing (35), this end provides a rotating engagement by catching between the fixed part (30-31) and the mobile part (1). <IMAGE>
