Abstract

Provided is a buried type hinge apparatus having an automatic return function in which a closing force of a door is provided with only a torsion spring. The hinge apparatus includes: a single body which is buried in a door; a shaft whose one end is projected through the upper cap and is rotatably supported; a piston which is slidably installed in the single body; a rotational / rectilinear motion conversion unit which converts a rotational motion of the shaft into an axial rectilinear motion of the piston according to opening and closing of the door; a damping unit that controls a descent and ascent speed of the piston, and provides a damping function selectively when the piston rises up; and a return unit that provides a restoring force for the rotational / rectilinear motion conversion unit so that the door is returned to an initial position of the door at the time of closing the door.

Description

technical field

[0001] The present invention relates to an embedded hinge device with automatic return function, in particular to an embedded hinge device with automatic return function, wherein the return spring is removed, thereby reducing the overall length of the hinge device, and the door The closing force of the torsion spring is provided only by the torsion spring associated with the engagement unit, thus increasing the efficiency of the torsion spring, which contributes more effectively to the opening and closing force of the door, and in this device, the torsion spring is increased length to compensate for the closing force of the door, and the inclination angle of the cam diagram is established to enhance the closing force of the door, thereby obtaining a compact structure and reliably realizing the automatic return function of the door. Background technique
