Description

[Detailed Description of the Invention] The present invention relates to an improvement in the structure of a cabinet in which the outer box of a refrigerator or the like is made of painted steel plates, and one of its purposes is to facilitate the assembly work.

Conventionally, in this type of cabinet structure, a configuration is known in which corner pieces made of synthetic resin are fitted as covers on the end faces of each corner of the front opening edge.

This type of corner piece is required to be easy to assemble and have a desirable appearance as a refrigerator.
The technology for forming cabinets using painted steel plates is new, and no specific technology has been proposed.Currently, the only technology available is to simply cover the ends of adjacent flanges.

The present invention provides a corner piece shape that satisfies the above requirements.

Hereinafter, the present invention will be described with reference to the accompanying drawings showing one embodiment thereof.

In the figure, reference numeral 1 denotes a refrigerator cabinet body formed from a painted steel plate 2. Molding of this cabinet body 1 will be explained below with reference to FIG. 2.

2 is a painted steel plate, and the surface of the steel plate 2a is coated with paint 2b in advance.
is painted.

A double flange 3 and a flange 4 are bent on both sides of the painted steel plate 2.

The double flange 3 constitutes the front opening edge 1' of the cabinet body 1, and includes a front flange 3a which is newly bent at a right angle on one side of the painted steel plate 2, and a predetermined interval R on the back side of this front flange 3a. A folded flange 3b that has been folded back, and a parallel flange 3 that is parallel to both flanges 3a and 3b.
It is composed of C.

Although not shown, the flange of the inner box is inserted between the folded flange 3b and the parallel flange 3C to form a refrigerator box.

5, 5, . . . are substantially V-shaped notches provided at appropriate positions on the double flange 3 and flange 4 at an angle of 90° or more.

The cabinet body 1 is bent at right angles at the notches 5, 5, . . . , and formed into a box shape as shown in FIG.

When the painted steel plate 2 is formed into a box shape in this way, the above-mentioned notch 5
, 5... is a groove 5 between adjacent double flanges 3, 3.
', 5' are formed.

These grooves 5', 5' are of course narrower than the notches 5, 5, but the width of the notches 5.5... is determined by bending the steel plate 2 into a box shape. At this stage, the angle (90° or more) is determined so that the grooves 5', 5' taper (V-shape) from the opening side toward the bent side.

A corner piece 6 is inserted into the grooves 5', 5', . . . and is integrally molded from synthetic resin.

This corner piece 6 has a triangular shape to fit between the end faces of the adjacent flanges 3, and
It is formed of a front part 6a which is flush with the plane A, and left and right support parts 6b, which are inserted at a predetermined interval R between the adjacent flanges 3, 3, respectively.

In the above configuration, this corner piece 6 is a groove 5' of the cabinet body 1 bent into a box shape.

It is assembled by inserting and fixing it into each of the support parts 6b, 6b from the opening side, and at this time, only the insertion work is required, which not only improves the assembly work, but also the support parts 6b, 6b. is the front flange 3a and the folded flange 3
The corner piece 6
Even when the corner piece 6 is inserted after the cabinet body 1 and the inner box are assembled, the corner piece 6 itself does not become an obstruction.

Note that the corner piece 6 has a front portion 6a as shown in FIG. 7A.
As shown in FIG. 7B, the end surfaces of adjacent flanges 3a may be covered, and furthermore, as shown in FIG. It is also possible to fix the anti-rust corner piece 6 on the end face of the painted steel plate 2 by filling it with

As is clear from the above embodiments, the cabinet of the present invention is
A double flange consisting of a front flange, a folded flange folded back at a predetermined interval on the back side of the front flange, and a parallel flange parallel to both of these flanges is formed on the painted steel plate, and furthermore, the double flange a notch is formed at an appropriate location, the painted steel plate is bent into a box shape at the notch portion to form a front opening edge on the double flange side, and a front opening edge is formed between the adjacent flanges formed by the notch. A corner piece is provided in the groove, and has a front part that spans the adjacent flanges, and a support part that is inserted within the predetermined interval. This greatly improves assembly work efficiency, and even when inserting another flange (for example, the flange of the inner box in a refrigerator cabinet) between the folded flange and the parallel flange, the corner piece can be easily inserted. It has various advantages, such as not being a hindrance, and the corner pieces can be attached in any order.
