KR200266905Y1 - Double-structured iron pieces (hinges) of different upper and lower shapes of left and right variable automatic opening and closing devices of door of refrigerator door type - Google Patents

Abstract

The present invention relates to a railway (hinge) in a left and right variable automatic opening and closing apparatus of a door of a refrigerator door, and is intended to facilitate the use of a door.

In the present invention, the upper part of the double structural steel piece when the iron piece (hinge) is coupled with the door is rotated steadily due to the front contact between the safety plate and the iron rotary frame, and the lower part is a steel piece connected to the door , The iron pieces in the rotating frame of the iron block the iron passage to prevent the door from being detached, so that the whole hard connection and the stable rotation are maintained.

Description

Double-structured iron pieces (hinges) having different shapes of upper and lower parts of left and right variable automatic opening / closing devices of door of refrigerator door type {omitted}

The present invention relates to an iron piece (hinge) in a left and right variable automatic opening and closing apparatus of a door of a refrigerator door type, which enhances the coupling force with the door and stably rotates the door, thereby facilitating the use of the door.

The function of the conventional invention is that two pieces of the railway passages (4,5) and the iron piece rotating frame (3) are connected by one groove on the upper end portion and the lower end portion of the refrigerator door, A safety plate 2 for preventing the door 6 is detached from the main body when the refrigerator door 6 is opened at the left and right sides at the same time between the iron passages 4 and 5 at the corners of the respective parts, . When the door 6 is opened, the iron pieces 1 in the open area are sequentially released from the iron frame 3 and the iron passages 4 and 5. At this time, (4a, 5a) which are not opened. At the same time, the iron frame 3a of the unrotated portion gradually rotates around the iron piece 1a, and the safety plate 2 pushed when the iron piece passages 4a and 5a are opened opens the passage. This happens from time to time on the left or on the right, and the refrigerator door (6) opens to the left and opens to the right. (Reference: Application No. 2001-0004715)

DESCRIPTION OF THE REFERENCE NUMERALS

1,1a: Double structural steel piece 2: Safety plate

3,3a: Rotary frame of upper and lower part of double structural steel piece

4, 4a: Upper part passage of dual structural steel piece

5, 5a: Lower part passage of dual structural steel piece

6: Door 7: Body

As shown in Figure 1, the upper part of the iron piece and the lower part of the iron piece are divided into different shapes. The upper part is made of cylindrical shape, and the lower part is made by cutting the both sides of the cylinder little by little to make the round part as a face, and the lower part has four faces as a whole, and the faces facing each other have the same characteristics. That is, if two faces are flat, the other two faces will have a round shape.

Dual structure The cylindrical shape of the upper part of the iron piece is in contact with the safety plate in the pivoting frame of the door, so it can withstand the external impact and smoothly open and close the door. On the other hand, because of the characteristic that the structural features of the sub-region, one side of the four sides and the side opposite to the other side are round and the other sides are flat, the round side helps to open the door naturally and stably, Since the iron piece prevents the detachment of the door from the body by blocking the iron passage, the double structure iron piece can prolong the life of the door.

Claims (1)

In the construction of the iron piece (hinge), the upper part and the lower part are divided into two parts and the shapes are different. The upper part is made up of a cylindrical shape, and the lower part is an extension of the upper part, and the rounded parts on both sides of the cylinder are slightly shaved on the basis of the cylinder. In the left and right variable automatic opening / closing devices of the door of the refrigerator door which constitutes the first round portion, followed by the plane, then the round portion, and then the four sides in a plane, Double-structured iron pieces (hinges) with different shapes.
