Connect the connecting protrusion 5 and the engaging part 11, and the connecting window 8 and the locking protrusion 12 to lock and fix the ceiling plate B, and insert the connecting vertical hole 6 in the bottom of the bottom box body A. The connecting vertical hole 7 and the engaging portion 14, the locking protrusion 9 and the connecting window 15 are connected, the bottom plate C is locked and fixed, and the main body is assembled.

The front plate stacking plate 22 and the front plate 16 are attached by connecting the locking portion 20 and the locking piece 21 to the drawer insertion opening 1 formed in each box body A of the assembled main body. Insert the drawn-out drawer D and assemble the product.

〔Example〕

The box A in the drawing has an opening 23 in the center, a protrusion 24 on the surface of the peripheral wall, engagement steps 25 and 26 on the connecting protrusion 4 and the connecting protrusion 5, and furthermore, the connecting protrusion 4. A connecting vertical hole 6 and through holes 27 and 28 are formed in the connecting protrusion 5, and connecting windows 8 are formed in the front and rear of the upper edges of the left side plate 2 and the right side plate 3, respectively.
The figure shows a case where a structure is adopted in which a total of four locking protrusions 9 are provided on the lower edges of the left side plate 2 and right side plate 3 corresponding to the connecting windows 8.

In addition, the top plate B in the drawing has a circumference 29 on the base plate 10.
The locking protrusions 12 are protruded from the inner wall of this peripheral flange 29 in correspondence with the positions of the connecting windows 8 of the box body A, and the connecting protrusions 4 of the box body A and the connecting protrusions 4 of the box body A are provided at the four corners of the base plate 10. This is a case where a structure in which the engaging part 11 fitted to the protrusion 5 is made to hang down is adopted.

In addition, the bottom plate C in the drawing has a peripheral flange 31 erected around the base plate 13 having an opening 30 in the center, and locking protrusions 1 of the box body A are provided at two places each on the left and right walls of the peripheral flange 31.
A connecting window 15 is provided in which 2 is locked, and engaging portions 14 that are fitted into the connecting vertical holes 6 and 7 are protrudingly provided at the four corners of the substrate 13, and the engaging portions 14 have through holes 32. A case is illustrated in which a structure in which a protrusion 33 is provided is adopted.

Further, the drawer body D shown in the drawing is provided with locking portions 20 having four windows 34 at each of the upper and lower edges of the front plate 16, and on the other hand, a protrusion 35 that is fitted into the windows 34 is provided. A front overlapping plate 22 with locking pieces 21 formed at four locations on the inside of the upper and lower edges is molded, and each protruding piece 35 of this front overlapping plate 22 is fitted into each window 34 of the front plate 16. This is a case where a structure in which the front overlapping plate 22 is fitted onto the plate 16 is adopted.

FIG. 1 shows a case where the boxes A are stacked in four stages.

In the figure, reference numeral 36 is a notch for inserting a hand, and reference numeral 37 is a caster with an insertion rod inserted into the through hole 32.

[Effect of idea]

Since the present invention is constructed as described above, it is lightweight, and in addition, the connection between the respective box bodies, the connection between the box body and the top plate, the connection between the box body and the bottom plate, and the formation of the drawer body are firm and easy. Thus, it is possible to provide a plastic multi-tiered organizer shelf that can easily assemble an arbitrary number of tiers of organizer shelves.
