Abstract
Device for balancing a lid of a suspended plan filing cabinet, comprising a stay (4) fixed at one end (40) on a pivot pin (5) fastened to the lid (1), the other end (41) being free, said stay being pulled towards the top of the cabinet by a spring (6) compensating the weight of the lid. The stay is guided by a roller (7) free to turn on a pin (8) fastened to the frame (2). This stay has a notch (9) which is entered by the roller (7) in order to hold the lid open, and a notch (10) holding the lid closed. Means of adjusting the tension of the spring (6) make it possible to fix a safety position (.alpha.) before the complete closure of the lid.
