Abstract

A hinge for a refrigerator includes a hinge support configured to be mounted on a front surface of a cabinet of the refrigerator, where the hinge support has a plate shape and defining a coupling hole, a hinge bracket including an insertion part configured to be inserted into the coupling hole, where the hinge bracket is coupled to the hinge support along a longitudinal direction of the hinge support, and a hinge pin that is configured to mount to the hinge bracket and that is configured to allow a door of the refrigerator to rotate about the hinge pin. The hinge support includes a bracket support that at least partially surrounds the coupling hole and protrudes from a front surface of the hinge support, the bracket support being configured to provide support to the hinge support.

First claim

What is claimed is:

1. A method for manufacturing a hinge for a refrigerator, the method comprising:
a process (S 100 ) of processing a hinge support and hinge bracket, wherein the hinge support is fixedly mounted on front surface of a cabinet and comprises:
a coupling hole; and
a bracket support which protrudes from a front surface thereof and disposed along an outside edge of the coupling hole, an end of the hinge bracket being closely attached to an inner surface of the bracket support,

and wherein the hinge bracket comprises an insertion part inserted into the coupling hole of the bracket support;
a process of temporarily assembling the hinge bracket to the hinge support so that the hinge support and the hinge bracket are assembled with each other in a direction crossing each other;
a process of pressing and fixing the hinge bracket, in which a rear end of the insertion part protruding to a rear side of the coupling hole is pressed to be closely attached to an inclined part disposed along a circumferential surface of the coupling part, thereby restricting the hinge bracket to the hinge support; and
a process of performing surface treatment for plating or painting surfaces of the hinge support and the hinge bracket which are coupled to each other.

2. The method according to claim 1 , wherein the hinge support is molded by using press processing, and
when a support recess part that is recessed from a back surface of the hinge support is molded, the bracket support is molded to protrude from a front surface of the hinge support so that the protruding volume of the bracket support corresponds to a recessed volume of the support recess part.

3. The method according to claim 2 , wherein a rear end of the insertion part is pressed and deformed so that the rear end does not further protrude from the support recess part.

4. The method according to claim 1 , wherein a rear end of the insertion part is pressed and deformed so that the rear end does not further protrude from the support recess part.

5. The method according to claim 1 , wherein, when the hinge bracket is molded, a pin insertion hole into which a hinge pin is inserted is formed in a top surface of the hinge bracket, and a stepped part in which the pin insertion hole is accommodated is formed on a bottom surface of the hinge bracket, and
after the hinge pin is inserted into the pin insertion hole, the hinge pin is fixed to the hinge bracket at the stepped part through welding or riveting.
