Title
(EN) DOOR CLOSERS AND DAMPERS PRIMARILY FOR DOOR CLOSERS
(FR) FERME-PORTES ET AMORTISSEURS CONÇUS ESSENTIELLEMENT POUR FERME-PORTES
Abstract
(EN)
A door closer for hingedly mounted doors comprises an actuator adapted for fitting within the thickness of a door and an anchor member adapted for fitting in a door frame such that when installed the closer acts to draw the door into a position of closure at a rate controlled by a fluid-filled damper (40) which comprises a cylinder containing hydraulic fluid, a piston (50) slidable longitudinally of said cylinder and dividing the cylinder into two chambers and a flow restriction assembly (60) associated with the passageway incorporated in said piston to limit the rate of flow of hydraulic fluid from one chamber to the other when the piston is moving in the door-closing direction. The flow restriction assembly defines a flow-restricting passageway including a slot (63) and to enable the flow restriction imposed on the hydraulic fluid to be adjusted when the door closer is installed and in use, the effective length of the slot is variable by relative positional adjustment of two elements (61, 65) by which the slot is defined. An adjustment member is provided within the cylinder to enable one of said passageway-defining elements (80) to be positionally adjusted relative to the other so as to vary the flow restriction imposed on the hydraulic fluid by the slot, the adjustment member having an operating element (85) which is accessible end-wise of the damper.
(FR)
Un ferme-porte pour portes montées sur charnières comprend un actionneur conçu pour s'adapter dans l'épaisseur d'une porte et un dispositif d'ancrage s'adaptant dans le cadre d'une porte de sorte que, une fois installé, le ferme-porte tire la porte dans une position de fermeture à une vitesse régulée par un amortisseur rempli de fluide (40) qui comporte un cylindre renfermant un fluide hydraulique, un piston (50) pouvant coulisser longitudinalement dans le cylindre et divisant ce dernier en deux chambres et un ensemble d'étranglement de l'écoulement (60) associé au passage incorporé dans le piston afin de limiter la vitesse d'écoulement du fluide hydraulique d'une chambre à l'autre lorsque le piston se déplace dans le sens de fermeture de la porte. L'ensemble d'étranglement de l'écoulement forme un passage d'étranglement de l'écoulement comportant une fente (63), et, afin de régler l'étranglement de l'écoulement imposé au fluide lorsque le ferme-porte est installé et en fonctionnement, on fait varier la longueur effective de la fente selon le réglage relatif de la position de deux éléments (61, 65) définissant la fente. Un élément de réglage est ménagé dans le cylindre pour permettre de régler la position des éléments formant le passage (80) de façon à modifier l'étranglement de l'écoulement imposé au fluide hydraulique par la fente, l'élément de réglage comportant un élément d'actionnement (85) qui est accessible en bout de l'amortisseur.
