Description

Hinge assembly

The present invention relates to a hinge assembly, and more specifically, to a hinge assembly that connects a main body of an item storage box and a cover and guides the cover to easily open and close the cover through rotation.

Generally, an item storage box consists of a main body and a cover, and the cover is opened and rotated through a hinge.

However, the hinge applied to the conventional storage box is a hinge structure in which a hinge pin is applied, which causes separation or shape deformation of the hinge pin and a gap occurs when the cover rotating around the hinge pin is seated on the main body. Or, there were many cases where the body and cover were misaligned.

Accordingly, in the past, as in Registered Patent Publication No. 10-0008625 and Registered Patent Publication No. 10-2428551, a technology was known to guide the opening and closing rotation of the cover by connecting a leaf spring to a hinge forming a wing-shaped structure.

However, the above-mentioned pre-registered patents also apply to the hinge pin, and this also causes a gap to occur when the cover rotating around the hinge pin is seated on the body due to the separation or shape deformation of the hinge pin or the main body. The problem of the covers being misaligned could not be completely resolved.
