Title
(EN) DAMPED SELF-CLOSING HINGE
(FR) CHARNIÈRE À FERMETURE AUTOMATIQUE AMORTIE
Abstract
(EN) A damped hinge comprising: a first leaf (32) for securing the hinge to a fixed support; a second leaf (35) for securing a moveable closure to the hinge; a barrel (33) secured to the first leaf (32), the barrel (33) including an axial bore (34); a piston (30) mounted for axial movement within the bore (34), the piston (30) including a cam surface (45); an axially extending member (39) constrained to rotate with the second leaf (35), the member (39) including a cam follower (42) arranged to engage the cam surface (45); the cam surface extending axially so that the piston (30) moves axially within the bore as the second leaf is rotated in relation to the first leaf; a hydraulic fluid contained within the bore (34); at least one of the piston (30) and member (39) including a passageway through which the hydraulic fluid may flow as the piston moves within the bore; wherein the passageway includes an adjustable valve (48, 49) to restrict the flow of fluid to damp opening or closing of the hinge.
(FR) L'invention porte sur une charnière amortie, qui comprend : une première feuille (32) pour fixer la charnière à un support fixe ; une seconde feuille (35) pour fixer une fermeture mobile à la charnière ; un tube (33) fixé à la première feuille (32), le tube (33) comprenant un alésage axial (34) ; un piston (30) monté pour un déplacement axial à l'intérieur de l'alésage (34), le piston (30) comprenant une surface de came (45) ; un élément s'étendant axialement (39) contraint à tourner avec la seconde feuille (35), l'élément (39) comprenant une contre-came (42) agencée de façon à venir en prise avec la surface de came (45) ; la surface de came s'étendant axialement de telle sorte que le piston (30) se déplace axialement à l'intérieur de l'alésage lorsque la seconde feuille est tournée par rapport à la première feuille ; un fluide hydraulique contenu à l'intérieur de l'alésage (34) ; au moins l'un du piston (30) et de l'élément (39) comprenant un passage à travers lequel peut s'écouler le fluide hydraulique lorsque le piston se déplace à l'intérieur de l'alésage ; le passage comprenant une vanne réglable (48, 49) pour restreindre l'écoulement de fluide pour amortir l'ouverture ou la fermeture de la charnière.
