Abstract

PURPOSE: To regulate the closing speed of a main body as desired by connecting a force storing mechanism to provide a door main body with a force in a clos ing direction and a buffer mechanism to control the closing rate of the main body by a pivot to form a hinge main body. CONSTITUTION: When a closing force is added to a door main body D, the main body D is biased in a closing direction by the elastic restoring force of a torsion spring 12. In addition, when a cylinder 31 is rotated together with a 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.
