Abstract

The present invention relates to an upper hinge assembly of a refrigerator door, and includes a base (14) fixed to an upper surface of the refrigerator cabinet (11) and a hinge support portion (15) bent upward therefrom, wherein the support portion has a hinge shaft hole ( 16 and a bracket 12 having a recessed portion 17 formed at one end thereof, the bracket 12 is rotatably mounted on the hinge support 15 of the bracket and has a rounded bottom, and has a hinge shaft 20 downward at the bottom thereof. ), A hinge portion 13 having a fixed body portion 21, an extension portion 22 extending to one side thereof and a screw hole 23 formed therein, and an inclination of the hinge shaft 20. The shaft portion 28 is fitted rotatably in a position fixed to the recessed portion 17 of the hinge support portion 15 of the bracket, and has a screw shaft 29 screwed into a screw hole formed in the extension portion 22 of the hinge portion. By including the adjustment screw 25, tighten the adjustment screw. The hinge is rotated clockwise or counterclockwise in conjunction with it when the screw is rotated in the direction of loosening or screwing. Therefore, the hinge axis fixed to the bottom of the hinge part rotates in the left and right direction when viewed from the front, thereby correcting the tilt of the hinge axis. Since it is possible, the state in which the hinge axis is inclined due to machining and assembly errors can be easily corrected.

Description

Upper hinge assembly for door of refrigerators}

The present invention relates to a hinge assembly designed to correct the inclination of a door that is rotatably mounted on the front of a large-sized refrigerator or showcase refrigerator for food storage, and more particularly, to a door hinge assembly that supports the door in a rotatable manner. The present invention relates to an upper hinge assembly capable of correcting an inclination of a refrigerator door by adjusting an inclination of the hinge by an inclination adjusting screw which is movable up and down.

In general, the refrigerator supports the door 1 by the lower hinge as shown in FIG. 1 and the upper hinge 2 is inserted into a hole 3 formed in the top surface of the door to simply keep the door in position. .

However, the hinge may be mounted inclined in the vertical direction due to an error in the manufacturing process of the upper end hole and the hinge of the door or the assembly of the hinge to the upper surface of the refrigerator cabinet. In this case, excessively frictional action is generated locally in the holes and hinges of the door, which leads to premature damage, and eventually the door is lengthened, resulting in the outflow of cold air from the refrigerating compartment or the freezing compartment.

In order to correct the inclination of the hinge shaft as described above, the hinge fixed to the four sides of the refrigerator cabinet is conventionally disassembled and remounted, and an assembly error may also occur, so that the process of assembling the upper hinge accurately and vertically is skilled. Requires skill

The present invention has been made to solve the problems of the assembly of the conventional refrigerator upper door hinge as described above, to provide a tilt correctable upper hinge assembly of the improved structure that can easily adjust the inclination of the upper hinge for the refrigerator upper door. For the purpose.

In order to achieve the above object, the upper hinge assembly for a refrigerator upper door according to the present invention has a base fixed to the upper surface of the refrigerator cabinet and a hinge support bracket having a cut-out portion which is bent upwardly and has a hinge through hole and one end opened, The bottom surface is curved and the hinge shaft is fixed downward on the bottom surface, the hinge portion is formed by the screw hole is formed in the extension extending to one side, the adjustment is screwed into the extension of the hinge portion is inserted through the incision of the hinge support of the bracket It includes a screw, the support pin through-hole is formed directly above the hinge shaft to support the hinge rotatably, is cut in the inclined surface of the bracket is bent at a right angle to the hinge support to form a support piece for supporting the support pin With adjustment screw in engagement with extension of hinge The support is configured such that the hinge axis tilt adjustment about the pin according to the.

Hereinafter, with reference to the accompanying drawings showing an embodiment of the present invention will be described in detail.

The tilt-adjustable upper hinge assembly for the refrigerator upper door of the present invention has a bracket 12 fixed to the upper surface of the refrigerator cabinet 11 by conventional fastening means such as a screw, as shown in the exploded view shown in FIG. The hinge portion 13 to be mounted and the adjustment screw 25 for adjusting the inclination of the hinge shaft fixed to the hinge portion by rotating the hinge portion in a state that the bottom surface is in contact with the bracket.

The bracket 12 includes a base 14 which is screwed onto the refrigerator cabinet 11 and a hinge support 15 which is bent upwards therefrom. The hinge support portion is formed with a long hole 16 through which the hinge shaft can penetrate, and a recess 17 formed by cutting one side end thereof.

In addition, the inclined surface 18 between the base portion 14 and the hinge support portion 15 of the bracket is formed with a support piece 19 cut in a c-shape and bent at right angles to the hinge support portion 15, on the opposite side thereof. The support piece 19 'which bent the free end of the base 14 upwards is formed.

The hinge portion 13 mounted on the support portion of the bracket includes a body portion 21 integrally with the hinge shaft 20 mounted through the long hole 16 of the bracket 12 and mounted to the upper door of the refrigerator. The body portion has a rounded bottom surface with a hinge shaft formed thereon, and a screw hole 23 is formed in the extended portion 22 extending laterally.

The body portion is formed with a hole in the width direction directly above the hinge axis, so that the support pin 24 is fixed through the holes formed in the opposite support pieces 19 and 19 'of the bracket so that the body portion supports the support pin 24. It can be rotated to the center.

The adjusting screw 25 is coupled to the screw hole 23 formed in the extension part 22, and the adjusting screw is spaced apart from the head 26 of the lower end by a distance corresponding to the thickness of the support part 15 of the bracket. It consists of the shaft part 28, the circular locking part 27 whose diameter is larger than the diameter of the shaft part, and the screw shaft 29 upward. The shaft portion 28 of the adjusting screw is inserted into a recessed portion 17 formed to be opened at one end of the support portion 15 of the bracket, and the shaft portion 28 is a screw hole 23 formed in the extension portion of the hinge portion 13. Screwed in.

Hereinafter, the tilt correction operation of the hinge shaft in the upper hinge assembly of the refrigerator door according to the present invention configured as described above will be described.

When the shaft of the adjusting screw is screwed into the screw hole of the hinge part and the adjusting screw is rotated in the direction of loosening the screw in the state shown in front view in FIG. 3, the adjusting screw 25 is fixed at the support of the bracket by the locking part. Since it is maintained in the position, the extension part 22 of the hinge part is moved upward, and rotates clockwise in the state shown in FIG. 3 around the support pin while the bottom surface of the body part is in contact with the support part of the bracket. As a result, the hinge shaft 20 integrally with the body portion rotates in a clockwise direction, and its tilt is corrected.

When the adjustment screw is rotated in the locking direction, the hinge shaft is rotated counterclockwise together with the body portion to correct the angle of the hinge shaft as the extension part 22 of the hinge portion moves downwards as described above. do.

As described above, according to the present invention, the screw shaft and the extension part of the adjusting screw are screwed together so that the hinge part rotates in a clockwise or counterclockwise direction by interlocking therewith by rotating the screw in the direction of tightening the screw or the unscrewing direction. Since the hinge shaft fixed to the bottom of the hinge portion is rotated in the left and right direction when viewed from the front, the tilt of the hinge shaft can be corrected, and thus the hinge shaft can be easily corrected due to machining and assembly errors.
