FIG. 6 is a cross-sectional view along the line, and FIG. 6 is a vertical cross-sectional view taken along line YY of FIG.

Referring particularly to FIG. 2 among these drawings, the box body is roughly divided into a bottom plate 10, a top plate 16, and a box body 11 in which the side plate 12 and the rear plate 14 are made of one plate member. It is configured. Although these plate members are generally sheet metal members, the present invention is not limited to this, and at least a part may be formed of plastic or the like.

The bottom plate 10 is composed of a single plate member, and both side edges are bent downward in a convex shape to form a convex portion 10A. In addition, the convex portion 10B is similarly formed on the rear side edge. On the other hand, the front edge is folded back upward to form a lower front bar portion 10D of the box body. Further, the four corners are cut out to receive the reinforcing members 18 and 20 described later to form cutout portions 10E and 10F.

As described, the box body 11 is composed of the rear plate 14 and the two side plates 12, and the lower edge of the rear plate 14 is bent inward to form the receiving portion 14B. On the other hand, the upper edge is bent inward to form a flange portion 14C bent in a direction perpendicular to the rear plate 14.

The lower edge of the side plate 12 is bent inward to form a receiving portion 12A. The convex portion 10A of the bottom plate 10 is superposed on the receiving portion 12A from above, and the convex portion 10B of the bottom plate 10 is superposed on the receiving portion 14B of the rear plate 14 from above. As described above, the bottom plate 10 is assembled to the box body 11.

Similarly to the rear plate 14, the upper edge of the side plate 12 is also formed with a flange portion 12C that is bent inward at a right angle. The front edge of the side plate 12 is bent inward to form a side front bar portion 12D of the box body.

In order to further reinforce the side plate 12, a front reinforcing member 18 and a rear reinforcing member 20 are provided along the vertical direction at the front and rear positions, respectively. The lower end of each of these reinforcing members reaches the bottom of the receiving portion 12A. On the other hand, two L-shaped members 22A and 22B, which will be described later, are arranged on the upper end of the front reinforcing member 18, and the top plate 16 is attached by engaging these L-shaped members. Further, since both of the reinforcing members are configured so as to be combined with the side plate 12 to form a cavity therebetween, each reinforcing member has a hook 26B of the bar member 28 for placing the shelf plate as shown in FIG. Is formed with a hole 26A for locking the. If this hole is formed, the bar member 28 can be held, and a shelf plate, a drawer or the like can be placed on the bar member 28. Further, when the bottom plate 10 is attached to the box body 11, the lower end of the rear reinforcing member 20 is contained in the cutout portion 10F of the bottom plate 10, and the lower end portion of the front reinforcing member 18 is cutout portion 10E. It fits in.

In order to strengthen the joint between the bottom plate 10 and the box body 11, the convex portions 10A, 10B and the receiving portions 12A, 14B are spot welded in places. Further, the rear reinforcing member 20 and the front reinforcing member 18 are respectively welded to the bottom plate 10, and the latter has a bracket member 30 as shown in FIG. 4 for the front reinforcing member 18 and the bottom plate 10. It is welded across the lower front bar portion 10D. For this reason, the front and rear reinforcing members 18 are a single plate and the edges thereof are bent, and together with the bottom plate 10 having high rigidity, they contribute to the improvement of the rigidity of the box body 11.

The top plate 16 has its edges 16C so that when the flanges 12C and 14C of the box body 11 overlap the edges 16C, the edges 16C are formed so that the upper surface of the box becomes a flat surface. Is formed by pushing down by the thickness of the plate. The front edge of the top plate 16 is folded back to form an upper front bar portion 16D of the box.

In order to describe the shapes of the front and rear reinforcing members 18 and 20, reference is made to FIG. 5, which is a cross-sectional view taken along the line XX of FIG. The front reinforcing member 18 arranged at the front portion of the side plate 12 has the cross-sectional shape shown in FIG. 5, and one end of the front reinforcing member 18 fits inside the end flange 12d of the side front bar portion 12D of the box body. As a result, it also reinforces the side front bar portion 12D. The rear reinforcing member 20 arranged at the rear has a cross-sectional shape shown in FIG. 5, and the respective flange surfaces 20a and 20b thereof are spot welded to the side plate 12 and the rear plate 14, respectively. Due to the presence of the rear reinforcing member 20 that forms a tubular shape with the box body 11, the corner portion of the box body is strongly reinforced.

Next, referring to FIG. 6 which is a vertical sectional view taken along the line Y-Y of FIG. 1, a reinforcing member 24 of the top plate 16 is fixed to an inner front portion of the top plate 16. The front end portion of the reinforcing member 24 is housed inside the end flange 16d of the upper front bar portion 16D of the box body to also reinforce the upper front bar portion 16D. Further, the reinforcing member 24 engages with the above-mentioned L-shaped members 22A and 22B to perform a holding action of the top plate 16. Further, looking at the upper part of FIG. 6, since the edge portion 16C of the top plate 16 is formed by pushing down by the plate thickness of the flange 14C on the upper surface of the box body as described above, when stacked, It can be seen that it forms a plane.

Further, in this embodiment, neither the top plate 16 nor the bottom plate 10 protrudes from the end plate flanges or the like on the outside of the side plate 12, so that the user's line of sight is maintained.
