These cabinets, lockers, book shelves, and product display shelves are generally built-in, but various types of assembling-type shelves such as book shelves and display shelves have been developed. However, in such a conventional assembly-type shelf, screw holes for locking the shelf plate at various height positions are opened in advance in the side frame supporting the shelf plate. Screw holes with different heights can be freely selected, a shelf plate with screw holes on the side is applied to the selected position, and screws are inserted into both screw holes from the outside of the side frame at that position. Assembly-type shelves that change the position of the shelf board up and down or increase or decrease the number of shelf boards by screwing are generally used.

  In order to assemble these assembling-type shelves, it is necessary to fasten a large number of screws through a screw hole together with a washer. For this reason, tools such as a screwdriver and a wrench are indispensable. In addition, the assembly is time consuming because many screws are tightened one by one, and even when screws are tightened, uniform tightening cannot be easily performed. There were many.

  Furthermore, these assembling-type shelves are generally of a size intended for use, and are simply assembled in order to reduce the volume of cargo during transportation. Although it is possible to arrange the same shelves side by side and connect them in the horizontal direction, if they are stacked in the vertical direction, the joining of the connecting parts becomes weak, so that they cannot be stacked in the vertical direction.

  On the other hand, as a display fixture that can display bottles of various sizes, has a simple structure, can recognize the entire picture of the product, and can take out the product from any level, it has column-shaped legs at the four corners of the product display tray. It is composed of a plurality of child trays that are attached to each other, and the legs of the child tray and the legs of the other child tray when used are stacked by fitting, and when stored, the goods displayed on the child tray and the goods on the other child tray There is a display fixture (for example, refer to Patent Document 1) that is stacked by stacking display trays.

Next, these two frame plates 1 folded at right angles are arranged face to face to form the block box frame 19 as shown in FIG. Next, the other one of the left and right insertion tongue pieces 11 facing each other on the side wall 10 of the left and right wall surface 2 of the frame plate 1 folded in one of the shape of the block box frame 19 is folded in the other mountain. The frame plate 1 is inserted into and fitted into the pores 17 provided on the upper, middle, and lower sides 13 of the upper and lower wall surfaces 3. At the same time, the other left and right push pieces 15 formed on the overlapped piece 14 outside the side 13 of the upper and lower wall surface 3 of the folded frame plate 1 are placed on the other pile. The left and right pushing pieces 15 cut and formed in the respective overlapping portions 14 are overlapped on the left and right rectangular holes 12 opened on the side 10 of the left and right wall surface 2 of the folded frame plate 1 and are respectively inwardly perpendicular to each other. Bend and engage the left and right ends of the rectangular hole 12.

  In this case, as shown in FIG. 8, if a space 22 of 3 to 4 mm, for example, is slightly opened between the left and right pushing pieces 15, the left and right pushing pieces 15 are pushed in the pushing direction 24 f by the pushing tool 24 to the inside. When it is folded, it does not protrude too much from the inside. Furthermore, as shown in FIG. 9, if the circular recess 23 is formed on the inner side in the longitudinal direction of the rectangular hole 12 positioned at the tip portion where the pushing piece 15 is inserted, the pushing piece 15 can be easily pushed. In order to bend the pushing piece 15 inward on the left and right, it can be easily done by pushing it with the tip of a screwdriver. However, using the pushing tool 24 shown in FIG. 7, the guide protrusion protruding from the tip of the pushing tool 24 as shown in FIG. 8 within the gap 22 between the openings of the left and right pushing pieces 15 in contact with the rectangular hole 12. 24a is pushed in the direction of arrow 24f. That is, a finger is put into the finger hole 24c, a palm is placed on the push plate portion 24d at the rear end of the grip portion 24e, the hand is held, and the push portion 24b expanding obliquely rearward is in contact with the left and right push pieces 15 while being pushed. Press to 24f. In this way, the central end portions of the left and right pushing pieces 15 are pushed into the front inside, and the rectangular hole 12 and the left and right pushing pieces 15 are easily engaged. In this way, the insertion tongue piece 11 is simply inserted into and engaged with the pore 17 and the left and right pushing pieces 15 are inserted into the rectangular hole 12 and bent inward to form the block box frame 19. By the above assembling method, the steel plate block box frame 19 having the cylindrical folded portion 9 having a U-shaped cross section is formed on the four rounds of the top, bottom, left, and right sides of the front and rear surfaces shown in FIG. 6A is a block box frame 19 having a square opening 18a as an opening 18 in the left and right wall surfaces 2, and FIG. 6B is a rectangular box as an opening 18 in the left and right wall surfaces 2.

In addition, the insertion is facilitated by making the shelf plate oblique. Further, a back plate can also be provided by fitting a cardboard plate made of a honeycomb structure or a plastic plate inside the block box frame 19 into the size of the inside of the block box frame 19. Further, instead of the back plate, the box is provided by means such as passing the brace diagonally to the back side of each block box frame 19 and locking the brace end to the end 9a of the cylindrical folded portion 9, for example. You may raise the intensity | strength of a frame or give decorating property.

  Further, a plurality of office desks are arranged facing each other so as to abut the top board, and the block box frame 19 is placed on the top boards of these office desks facing each other so as to straddle the boundaries of these top boards. By combining and placing a plurality of bookshelves, it is possible to easily form a bookcase serving as a partition wall on the office desk. By the way, the border of the top of the office desk is often fitted with a border frame, and the desk mating part often protrudes. For this reason, when shelves are installed so as to straddle between the desks that face each other, there is a drawback that they are likely to wobble and are not sat down. The block box frame 19 according to the present invention can be installed so as to straddle the portion with the tubular folding portion 9 even if the mating portion of the desk protrudes. That is, since the load of this article is supported by the cylindrical folding part 9 in the lower part on the front side and the cylindrical folding part 9 in the lower part on the back side, the cylindrical folding part 9 in the lower part on the front side is placed on the top plate of one desk. By placing and placing the cylindrical folded portion 9 at the lower part on the back side on the top plate of the other desk, the mated portion of the desks that are butted can be used independently of the protrusion.

  Further, after a plurality of block box frames 19 are combined, for example, when a lighting fixture is arranged inside the uppermost block box frame 19, light leaks out from the slit-shaped opening 18 to the outside. Because it illuminates, the surrounding atmosphere can be aesthetically pleasing and an excellent production can be achieved.
