Description

Furniture hinge {Door hinge}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge for a furniture, and more particularly, to a hinge for a furniture, which is used for furniture such as a sink and the like, and can be opened and closed according to an external force applied to the door.

Generally, a hinge is used as a part for fixing a door to a main body of a furniture such as a door or a sink. Such a hinge allows the door to be pivotally connected to the main body so as to smoothly open and close the door.

However, unlike a hinge installed on a door, a hinge installed on a furniture such as a sink has a function of not only simply connecting the main body and the door but also a function of keeping the door at a certain distance from the main body when the door is opened, Should be able to.

For example, the hinge provided on the sink includes a fixed piece attached to the body of the sink, a movable piece attached to the door, and a connecting body provided between the fixed piece and the movable piece, And the door is opened and closed to the front of the main body of the sink to open and close the inside of the sink.

According to the related art, Korean Utility Model Registration No. 20-0454244, which is registered in the Republic of Korea, includes a body formed with a fixing piece on the lower side and hollow inside and coupled to the body of the sink; A first connecting piece and a second connecting piece hinged to the tip side of the body by first and second hinge pins; A cylinder rod having a coupling protrusion which is inserted into the inside of the body and is connected to the rear end side by a connecting pin on the outer side of the rear end and has a rear end portion on the inner side and a distal end portion protruding on the outer side, An inner washer fixed to the rear end inner side, an outer washer for preventing the cylinder rod from being completely disengaged from the cylinder rod, a packing positioned and fixed to the inner side of the outer washer, A hydraulic cylinder composed of a spring for pushing the cylinder rod and oil filled in the cylinder; Wherein a coupling part hinged by the third hinge pin and the fourth hinge pin is formed by being inserted into the center of the center and the coupling part extended from both sides of the coupling part is extended from the door, A hinge for a sink having a hydraulic cylinder is disclosed.

However, in the related art, there is a problem that the body is fixedly coupled to the fixing member coupled to the body of the sink so that it is difficult to easily assemble and separate the body and the door, and transportation efficiency is reduced.

In addition, when the door is repeatedly used and a clearance is generated in the hinge, the fixing force of the door to the sink body is lowered, thereby failing to open and close the door smoothly.
