IMPROVED HINGE ASSEMBLY

The present invention discloses an improved hinge assembly in which a hinge rotation body and a hinge support body are hinged to each other, and the hinge rotation body is provided with a locking member, wherein: when the hinge rotation body and the hinge support body are hinge-rotated, the locking member locks the hinge-rotated hinge rotation body and the hinge support body together to thus secure the rotated state while having a seesaw motion in left and right directions; and, when pulling the hinge support body from the hinge rotation body, the locking is released and the hinge rotation body is unfolded from the hinge support body, so as to connect the hinge rotation body to a rotating object while connecting the hinge support body to a support object, whereby the rotating object may be hinge-rotated and fixed toward the support object or may be returned to its original position to thus significantly improve convenience as well as usability. Further, since the above components are locked or unlocked based on the left and right seesaw movement due to displacement of center of gravity of the locking member, a simple configuration may be adopted to greatly improve productivity as well as assembly efficiency and reduce production cost.
