Abstract: A hinge for a self-closing door includes a pair of hinge leaves having their respective knuckles joined to a hinge pin, one of the hinge leaves being fixed to the hinge pin and the other rotatable with respect to the same. A torsion spring is wound when the door to which the hinge is attached is opened. The torsion spring exerts a returning force which tends to keep the door in a closed position. Friction means is employed to arrest the closing of the door to prevent slamming. The friction means includes a first and second set of alternately interleaved friction plates, one set of which rotates while the other remains fixed when the door is allowed to close. The rubbing of the friction plates generates a retarding force which arrests the closing of the door. An adjusting member is also added to vary the amount of friction between the friction plates with the degree of opening of the door.

Abstract: A door accessory, such as a door hinge or a door check, includes a hydraulic retarding device for cushioning the closing action of a door. The hydraulic retarding device has a cylinder body which confines a fluid receiving space to receive hydraulic fluid therein. One end of a piston rod extends into the fluid receiving space and has a valve unit provided thereon. The valve unit includes a piston which is formed with perforations and which forms a clearance with the cylinder body and a valve ring which is loosely sleeved on the piston rod. The piston rod is operably associated with the door movement so that the valve ring does not block the perforations on the piston during a door opening action, thereby permitting faster fluid flow inside the fluid receiving space and providing little or no resistance to the movement of the piston rod, and so that the valve ring blocks the perforations on the piston during a door closing action, thereby permitting fluid to flow only through the clearance so as to retard the movement of the piston rod.

Abstract: A door hinge includes a hydraulic retarding device for cushioning the closing action of a door. The hydraulic retarding device has a cylinder body which confines a fluid operating space to receive hydraulic fluid therein. The fluid operating space includes a pair of longitudinally extending cylindrical spaces and an intermediate longitudinal passage provided between and communicating the cylindrical spaces. A vane unit is provided in each of the cylindrical spaces and has a blade which defines a longitudinal clearance with an inner surface of the cylinder body. A baffle extends longitudinally into each of the cylindrical spaces and is disposed between the passage and a respective one of the vane units. The baffles are substantially arc-shaped in cross-section and face away from each other. A gate valve is provided in the passage between the baffles. The vane units are operably associated with the door movement so as to open the gate valve to permit the hydraulic fluid to flow through the passage during a door opening action and so as to close the gate valve to prevent the hydraulic fluid from flowing through the passage and to permit the hydraulic fluid to flow only through the clearance between the vane units and the inner surface of the cylinder body in order to retard the movement of the vane units during a door closing action.
