CA 2687215

A hinge (1) for a door opening over a horizontal axis, of the type comprising first and second supports (2, 3) that can be fixed to a compartment structure and to a door, at least rotatably constrained to each other through a pin (10). The hinge (1) comprises a fluidic cylinder-piston damper (9) of the type with internal flow leakage of the fluid contained therein. The damper (9) has a piston (18, 19) with a through-hole (20). The piston (18, 19) can have an appendix (19) that non-sealingly engages a chamber (17) when the door is closed, to increase the dampening. The hinge (1) has elastic means (7) such as a spring, to counteract the falling movement of the door when it is opened. The hinge (1) can be of the cam type, with a cam (4) and an abutment (5).

L'invention concerne une charnière (1) permettant l'ouverture d'une porte sur un axe horizontal, du type comprenant un premier et un second support (2, 3), ces supports pouvant être fixés à une structure de compartiment et à une porte, et étant respectivement liés au moins en rotation par une tige (10). Cette charnière (1) comprend un amortisseur fluidique (9) à cylindre et piston du type à écoulement interne du liquide y contenu. L'amortisseur (18, 19) comporte un piston (18, 19) possédant un trou traversant (20). Le piston (18, 19) peut comprendre un appendice (19) entrant en contact non étanche avec une chambre (17) lors de la fermeture de la porte, ce qui améliore l'amortissement. La charnière (1) comporte un moyen élastique (7), tel qu'un ressort, dont l'action s'oppose au mouvement de descente de la porte lorsqu'elle est ouverte. Ladite charnière (1) peut être du type comprenant une came (4) et une butée (5).
