Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to the casing of an electric refrigerator, and more specifically, to the improvement of the front upper corner portion thereof.

[Technical background of the invention] FIG. 4 shows an exploded perspective view of a corner portion of an electric refrigerator that was actually applied to a product of the present applicant. To explain this as a conventional example, when combining the top plate and the side plates, the front edge 2 and the upper edge 3 of the side plate 1 are bent and formed at almost right angles in the same direction, and the other top plate 4 A flange 5 having a predetermined step is provided on the flange 5 so that the flange 5 is inserted into the lower surface of the upper edge 3. In that case, in order to strengthen the connection between the two, for example, a first fastening piece 6 is formed at a position closer to the front side of the flange 5, and a second fastening piece 7 is formed on the upper edge 3 of the side plate 1. They are arranged in series, overlapped and riveted.

However, according to this, the joint state of the front corner portion is exposed, so a separately prepared cover (not shown) is attached to that portion. Therefore, as the number of partial points increases, the number of working steps also increases, and improvements have been desired in terms of cost and productivity.

[Purpose of the invention] Therefore, the object of this invention is to provide a casing of an electric refrigerator whose front corner portions can be neatly finished with a simple operation without using a cover member or the like.

[Example] Hereinafter, this invention will be explained in detail with reference to the example shown in FIGS. 1 and 2.

In FIG. 1, 10 is a side plate, and 20 is a top plate. The side plate 10 is provided with a front edge 11 and an upper edge 12 bent in the same direction at approximately right angles, while the side edge of the top plate 20 is provided with a flange 21 formed with a predetermined step. are installed in succession. Note that the front edge portion 11 is formed with a folded portion 13 formed by folding the end portion twice, and a folded portion 13 is formed by folding the end portion twice.
An insertion piece 23 bent into a substantially L-shape and inserted into the folded portion 13 is connected to the downwardly bent front edge 22 of the 0.

Therefore, by inserting the flange 21 along the lower surface of the side edge portion 12 and simultaneously inserting the insertion piece 23 into the folded portion 13, the top plate 20 and the side plate 10 can be separated.
According to this invention, a notch 14 is formed in a portion of the upper edge 12 closer to the front side to allow a portion of the flange 21 inserted into the lower surface thereof to come out. , in this connection, the upper part of the front edge 11 has a notch 14 thereof.
A blindfold plate 15 having a shape that complements the above is integrally molded. This blind plate 15 is bent so as to be stacked on the flange plate 21, and the blind plate 15 and the flange plate 21 are provided with through holes 16 and 24 that are coaxially aligned. ,
Both are firmly fixed by rivets 17 inserted into the through holes 16 and 24. FIG. 2 shows the state in which they are joined by rivets 17. In addition, in this embodiment, a reinforcing metal fitting 30 is used to reinforce the joint portion. This reinforcing metal fitting 30 consists of an inverted L-shaped cross section member formed to be applied to the inner wall surface of the side plate 10, the lower surface of the flange 21, and the lower surface of the top plate 20, respectively, and the part that is applied to the lower surface of the flange 21. A through hole 31 is provided coaxially with the through holes 16 and 24, and the flange 21 is firmly attached to the lower surface of the flange 21 with a rivet 17. Further, this reinforcing metal fitting 30
Mounting support legs 32, 3 that are locked to the folded portion 13 of
2 is provided.

That is, as shown in FIG. 3, an engagement hole 13a is formed in the folded portion 13, and the reinforcing metal fitting 30 has its mounting support leg 32 inserted into the engagement hole 13a.
3a, the through-hole 31 is aligned coaxially with the through-holes 16 and 24, and is temporarily fixed to the side plate 10. After that, the side plate 10 and the top plate are attached with the rivets 17. 20 is integrally assembled. In this way, the corner portions of the casing are reinforced by the reinforcing metal fittings 30.

[Effects] As explained above, according to this invention, the blind plate 15 that complements the notch 14 is provided in a row on the front edge 11 of the side plate 10 in a bendable manner, so that the front corner of the casing is You can finish it neatly with simple work.

[Brief explanation of the drawing]

Fig. 1 is an exploded perspective view of an embodiment according to this invention, Fig. 2 is a perspective view showing the same embodiment when assembled, and Fig. 3 shows the reinforcing metal fittings shown in Fig. 1 attached to the side plate. FIG. 4 is an exploded perspective view showing a conventional example. In the figure, 10 is a side plate, 11 is a front edge, 12 is an upper edge, 13 is a folded part, 14 is a notch, 15 is a blindfold, 16 is a through hole, 20 is a top plate, 21 is a flange, and 24 is a The through hole 30 is a reinforcing metal fitting.

Claims (1)

[Claims for Utility Model Registration] (1) Includes a pair of left and right side plates 10 and a top plate 20 disposed above them, with the front edge 11 and upper edge 12 of the side plates 10 substantially in the same direction. The side plate and the top plate can be combined by bending the top plate 20 at right angles, and by connecting a flange 21 having a predetermined step to the side edge of the top plate 20 and inserting the flange 21 into the lower surface of the upper edge 12. In the case of the electric refrigerator, a notch 14 is formed on the front side of the upper edge 12 of the side plate 10 to allow a part of the flange 21 to come out to the surface, and the front edge 11 is provided with the notch 14. A blindfold piece 15 that complements the above is integrally molded, through-holes 16 and 24 are bored coaxially with the blindfold piece 15 and the flange 21, and the blindfold piece 15 is superimposed on the flange 21. A casing of an electric refrigerator characterized in that the blind piece 15 and the flange 21 are fixed to each other by inserting rivets 17 into the through holes 16 and 24. (2) The casing of an electric refrigerator according to claim (1), characterized in that a reinforcing metal fitting 30 is attached to the back surface of the joint between the blind piece 15 and the flange 21. (3) In claim (2) for utility model registration, the reinforcing metal fitting 30 is a metal member having a substantially L-shaped cross section extending from the inner wall surface of the side plate 10 to the lower surface of the top plate 20 along the lower surface of the flange 21. A casing for an electric refrigerator, comprising a plate, and the metal plate is provided with a rivet insertion hole for fastening with the flange 21.
