Abstract
PURPOSE: To facilitate the control of a buffer force and to increase the capacity of a hydraulic chamber by providing a gear transmitting mechanism with an intermediate gear between a pivot shaft and the pivot of an auto-hinge main body. CONSTITUTION: When a door main body D is released from an opening force, a pivot 11 is rotated by the elastic restoring force of a torsion spring 12, and a gear 8 and an intermediate gear 6 are rotated to bias the main body D in a closing direction. In addition, when a cylinder 31 is rotated together with the pivot 11, and a piston 32 starts to move downward, hydraulic oil in a first hydraulic chamber (a) is compressed to operate a check valve 37 and comes into a circular hole 34. Then, with its quantity of flow restricted by a pressure compensated flow control valve V1 , the oil is passed through an oil path 40 and flows back into a second hydraulic chamber (b) from the opening of the cylinder 31, the piston 32 is slowly lowered to move the main body D slowly in the closing direction. Further, when the oil path 41 of the cylinder 31 is opened, the oil in the hydraulic chamber (a) is passed through the flow control valves V1 and V2 and flows back into the second hydraulic chamber (b) to accelerate and close the main body D.
