Automatic door closing arrangement - uses hydraulic piston cylinder system for damping

The arrangement consists of a cylinder which is filled with a hydraulic fluid and in which a spring loaded piston (4) can slide. A shaft, which operates the door, is connected to the piston. The piston is loaded by two springs (8,10) which act at one end against the main piston and at the other end against a second piston (9) which forms the axially movable wall of a pressure accumulator. The pressure accumulator is automatically charged when the door is closed over a certain angle. It is discharged when the door is opened also over a certain angle.

Damper and method of controlling a door.

A door closer comprises a housing containing a cylinder and two movable pistons. When the associated door is opened, both of the pistons and the cylinder are moved relative to the housing to draw oil into the cylinder. Expulsion of oil from the cylinder through an orifice on closing of the door controls the closing movement.

DEVICE FOR AUTOMATIC CLOSING OF A DOOR.

AUTOMATIC DOOR CLOSER

L'invention est relative à un ferme-porte automatique comportant un dispositif d'étranglement, un clapet de retenue et un clapet anti-retour entre la chambre de pression et la chambre sans pression. Selon l'invention, le clapet de retenue est maintenu dans sa position d'obturation à l'aide d'un élément élastique dont la force de retenue peut être surmontée par un mouvement de l'arbre du ferme-porte. Le ferme-porte est esthétique et assure la fermeture automatique de la porte quel que soit son angle d'ouverture. The invention relates to an automatic door closer comprising a throttling device, a check valve and a non-return valve between the pressure chamber and the pressure-free chamber. According to the invention, the check valve is held in its closed position with the aid of an elastic element, the retaining force of which can be overcome by a movement of the shaft of the door closer. The door closer is attractive and ensures automatic closing of the door regardless of its opening angle.

UNIVERSAL DOOR CLOSER

1515217 Door closers VEREINIGTE BAUBESCHLAGFABRIKEN GRETSCH & CO GmbH 19 July 1976 [7 Aug 1975] 29919/76 Heading E2M A door closer includes a spindle 2 protruding from a housing 1, a closer spring 7 and, laterally beside the spring 7, a piston 9 and cylinder 6 of a damper 8, the spindle 2 carrying two cam discs 3, 4 which act respectively on the spring 7 and damper 8 on rotation of the spindle 2, in each case through a rocker arm 13, 25. Each rocker arm 13, 25 abuts through a roller 17, 28 on the cam disc 3, 4 and through another roller 12, 29 on the spring 7 or damper 8, the rocker arms 13, 25 being mounted approximately opposite to one another at 14, 26 in the housing 1. The longitudinal axes 19, 31 of the spring 7 and damper 8 remain fixed relative to the housing 1. Preferably as shown, the spring 7 is arranged parallel to but higher than the damper 8 in the housing 1. The spring 7 is guided in a cylinder 5 and surrounds and abuts against a bolt 11 which carries the roller 12. The run-off face 18 of the arm 13 is so curved that its tangential surface at its contact with the roller 12 is always perpendicular to the axis 19. The roller 29 is mounted in a recess 35 of the rocker arm 25 and abuts on a run-off face 30 provided on an extension of the piston 9. The stress in the spring 7 is adjusted by means of a screw 22 seated eccentrically in a disc 20 which has a collar 21 bearing on the end of the spring 7 remote from the bolt 11. The disc 20 has a recess 24 into which fits a circlip 23 on the screw 22 at maximum spring stress.

Patent FR1587528A

Door closer

ABSTRACT OF THE DISCLOSURE A door closer of the kind including a tension member (20) acted on by spring means (26) under the control of a uni-directionally operative fluid-filled damper which serves to regulate the rate of movement of a door (D) in the direction of closure without restricting signifi-cantly the rate of movement in the direction of opening, includes a fluid by-pass (39) in the damper and operative over the final part of the closure movement to remove the restraint imposed by the damper, and means, operative when the closer is installed, to vary the point in the closure movement at which the fluid by-pass becomes operative, so as to provide compensation for variations in the installation of the closer and variations of the gap between the door and its frame.
