Abstract

1,050,496. Door closers. VEREINIGTE BAUBESCHLAGFABRIKEN GRETSCH & Co. G.m.b.H. Dec. 21, 1964 [Dec. 24, 1963], No. 51954/64. Heading E2M. In a closing device for doors in which a closer spring 8, Fig. 2 (not shown) and a hydraulic damping arrangement 9 both act on individual rocking arms operated by individual cams mounted on the door pivot spindle, the bore of the damping arrangement cam 7 Fig. 3 (not shown) is provided with stop surfaces 25, 26 which are aligned with abutment surfaces 28 on the spindle so that relative movement between the cam 7 and the spindle is possible. The hydraulic damping arrangement 9 consists of a cylinder 42 containing a piston 43 which is connected by a piston rod to the end of rocking arm 16 and houses a piston spring 40, said piston 43 acting at the end of its stroke to open a valve 47 in the end of the cylinder. Said valve 47 when operated by the piston 43 reduces the pressure in the cylinder as the cam 7 passes the "door closed" position and the cam 7 is rotated relative to the spindle by the piston spring 40. The valve 47 can also act as a pressure-relief valve for the cylinder. Before the valve 47 is operated a damping hydraulic pressure is achieved by restricting the flow of oil through a channel 44 in a pin 45, the amount of restriction being adjustable by a regulating screw 46.
