Abstract: A multipurpose hinge apparatus having an automatic return function is provided in which the apparatus is installed between the door and a main body. The apparatus includes a driving mechanism for ascending and descending a piston rod according to opening and closing of the door which is installed in the upper portion of a cylindrical housing. A piston is connected with the piston rod, in which a one-direction check valve is installed in the piston. The piston partitions an upper chamber and a lower chamber and ascends and descends in association with the piston rod. A first oil path communicates with the upper and lower chambers via the lower portion of the piston rod in the central portion of the piston. A compression spring which makes the piston ascend is inserted into the lower chamber. Oil is filled in the chamber. Thus, the hinge apparatus is automatically returned to the initial position with return speed in multiple steps by controlling an amount of oil flowing from upper chamber to lower chamber in multiple steps when a door is closed.

Abstract: A hinge apparatus includes an upper body, a lower body, a shaft whose lower end portion is rotatably installed in the lower body, a piston whose outer circumference is slidably installed along the inner surface of the lower body, a rotational/linear motion converter which converts a rotational motion of the shaft into an axial linear motion of the piston, a damping unit provides a damping function selectively where the piston ascends according to return of the door, a torsion spring rotates the shaft in the door closing direction, and a clutch unit for stopping the elastic force due to reverse twisting of the spring or for restoring the elastic force of the spring.
