Description

[Detailed Description of the Invention] The present invention relates to a device for attaching the back plate of article storage furniture such as filing cabinets and steel bookshelves, and allows for secure attachment with an extremely simple operation.

The details will be explained below with reference to the illustrated embodiment. In FIG.
are integrally assembled on the underframe a with the central side plate 2 in common.

Figure 2 shows the rear plate 5 attached to the top plate 3 and the bottom plate 4. To attach the rear plate, a downward-pointing claw is attached to the rear edge of the horizontal plate part 6a having an appropriate width as shown in Figure 3. piece 6b, an upper mounting piece 6 having an engaging convex portion 6c with a hook-shaped cross section projecting downward in the same direction as the claw piece 6b on the front edge, and, although not shown, the upper mounting piece 6 is turned upside down and attached to a horizontal plate. A lower mounting piece 6' is provided on the rear edge of the portion 6a, and a lower mounting piece 6' has an upwardly directed claw piece 6b' and an upwardly protruding engagement protrusion 6c' on the front edge. The engaging convex portion 6c of No. 6 is engaged with the upward concave portion 3'' provided at the lower edge of the bent plate portion 3' at the rear edge of the top plate 3, and the horizontal plate portion 6a is It passes through a through hole 7 drilled at an appropriate location and projects rearward, and its downward claw piece 6b is engaged with an engagement hole 8 drilled at a corresponding position on the upper surface of the rear plate 5.

Also, in the lower part, similarly to the upper part, the engaging protrusion 6c' of the lower mounting piece 6' is engaged with the downward concave part 4'' provided on the upper edge of the bent plate part 4' on the rear edge of the bottom plate 4, and the horizontal The plate portion 6a passes through a through hole 9 formed in the bent plate portion 4' and projects rearward, and the upward claw piece 6b' thereof is formed in an engagement hole 10 in a position corresponding to the lower surface of the rear plate 5. In FIG. 1, 11 is a door provided on the front of the box body 1, and 12 is a drawer.

To assemble this box body 1, for example, first, the upper and lower rear plate mounting pieces 6, 6' are made to have their horizontal plate portions 6a projecting rearward from the through holes 7, 9 of the top plate 3 and the bottom plate 4, respectively. The engaging protrusions 6c and 6c' are connected to the top plate 3.
and are attached to the top plate 3 and the bottom plate 4 by engaging with the respective concave portions 3'' and 4'' of the bottom plate 4.

Next, the bent plate portion on the side edge of the bottom plate 4 is screwed to the side plate 2. Further, in the central side plate 2, the side edges of the adjacent bottom plates 4, 4 are fastened with bolts and nuts via this side plate 2. Next, the engagement hole 10 on the lower surface of the rear plate 5 is engaged with the claw piece 6b' of the lower mounting piece 6', and the rear plate 5
After locking the claw piece 6b of the upper mounting piece 6 in the engagement hole 8 on the top surface, the bent plate part on the side edge of the top plate 3 is screwed to the side plate 2, and the adjacent part in the center part is connected via the side plate 2. By tightening the side edges of the top plates 3, 3 with bolts and nuts, the rear plate 5 is held by the upper and lower mounting pieces 6, 6'.
In addition, since the engaging protrusions 6b and 6b' of the mounting pieces 6 and 6' are engaged and held in the recessed parts 3'' and 4'' of the top plate 3 and the bottom plate 4, respectively, the rear plate 5 is firmly attached to the top plate. 3 and bottom plate 4
mounted on. Further, by connecting the adjacent top plates 3, 3... and bottom plates 4, 4... through the side plates 2, as described above, it is possible to obtain the integrally connected boxes 1, 1... Since the rear plate 5 can also be attached at the same time, the rear plate can be attached extremely easily and conveniently even in locations where it is difficult to attach the rear plate, such as when installing along a wall. The engaging protrusions 6b, 6b' have a cross section U
It may also be formed into a letter shape or the like.

The rear plate mounting device of the present invention is easy to install as described above, and since the mounting pieces 6 and 6' can be attached to the top plate 3 and bottom plate 4, respectively, when assembling the box body 1, There are no protrusions on parts such as plates and bottom plates, making storage and packaging easier, and the mounting pieces 6, 6'
It has practical effects such as being extremely easy to manufacture since it can be used upside down with the same shape and dimensions.
