HINGE APPARATUS HAVING AUTOMATIC RETURN FUNCTION FOR USE IN BUILDING MATERIALS
摘要
<p>A hinge apparatus having an automatic return function for building materials is provided, in which a return spring is removed to thereby offer a closing force of each door with only a torsion spring. The 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 according to rotation of the door; a damping unit which provides a damping function selectively where the piston ascends according to return of the door; a torsion spring which rotates the shaft in the direction returning the door at the closing time; and a clutch unit for stopping an increment of an elastic force due to reverse twisting of the spring where an opening angle reaches a clutch stop start angle, or for restoring the elastic force of the spring.</p>
