  However, in this shelf mounting structure, the side edge of the shelf is simply placed on the shelf receiving frame material, so that the shelf is unexpectedly lifted from the shelf receiving frame material. There is a risk of detachment from the frame material. For this reason, a shelf fixing hole and a pin insertion hole that communicate with each other are provided on the vertical surface of the shelf receiving frame member and the side end surface of the shelf, and a certain length is provided from the pin insertion hole provided on the shelf. Although it is conceivable to prevent the shelf board from being lifted by inserting the straight pin having a through-hole into the shelf board fixing hole of the shelf board receiving frame member, according to such a shelf board mounting structure, When a heavy object is placed on the plate, the shelf plate tries to bend downward and a large pulling force acts on the pin to remove the pin from the pin insertion hole, causing the pin to come off or the shelf plate to bend downward. There is a possibility that the placement state of the article becomes unstable.

  The present invention has been made in view of such problems, and the object of the present invention is to reliably prevent the pins from being pulled out and the shelf from bending downward even when a heavy object is placed on the shelf. Thus, it is an object of the present invention to provide a shelf mounting structure in an assembly shelf that can always place a stable article.

The both side edge portions of the shelf boards 6 and 6 are installed and supported between the horizontal frame members 4 and 4 on both sides connecting the two. That is, between the upper half of the horizontal frame members 4 and 4 on both sides, which are partitioned through the partition rods 20 of the horizontal ridges 4a and 4a for the shelf receiving the projecting toward the back side (inner side). Pins provided on the side end faces 6a on both sides of the shelf boards 6 and 6, with the bottom surfaces of both ends of the shelf boards 6 and 6 placed between the upper half and the rear half part, these shelf boards 6 and 6 being juxtaposed in the front and back. The bent pins 9 and 9 are removably inserted from the insertion holes 7 and 7 into the shelf fixing holes 8 and 8 provided in the horizontal frame member 4 that match the pin insertion holes 7 and 7, respectively. The shelf boards 6 and 6 are fixed.

  Furthermore, the slit-shaped locking holes 11 and 11 provided on the inner side surfaces of the front and rear support columns 1 and 1 and the intermediate support column 2 between the upper and lower horizontal frame members 4 and 4 are provided at both ends of the shelf support frame member 5 on the outer side. The shelf support frame material 5 is removably attached by inserting and locking the locking protrusions 5b, 5b protruding toward the surface (surface side). Specifically, the shelf board receiving frame member 5 is arranged at a desired height position between the front column 1 and the intermediate column 2 and between the rear column 1 and the intermediate column 2, and locking protrusions at both front and rear ends thereof. 5b and 5b and the insertion pieces 5c and 5c at both front and rear ends protruding below the locking projections 5b and 5b are connected to the vertical locking holes 11 and 11 of the column 1 and the vertical column of the intermediate column 2 The shelf board receiving frame member 5 is mounted between the inner side surfaces of the support column 1 and the intermediate support column 2 by being inserted and locked into the stop holes 11 and 11.

  After that, from the fixing pin mounting holes 10, 10 drilled at both ends in the length direction of the shelf receiving frame member 5, the support columns 1, 2 that match these fixing pin mounting holes 10, 10 are used. A shelf receiving frame material between the support columns 1 and 2 by removably inserting a straight pin (not shown) into the fixing holes 12 and 12 provided in the side portions of the locking holes 11 and 11. 5 is fixed.

  Thus, a plurality of shelf board receiving frame members 5 are mounted at the desired height positions of the columns 1 and the intermediate columns 2 as described above, and then the shelf board receiving frame members 5 facing left and right at the same height position. 5, the shelf plate 6 is installed between the two sides of the shelf plate 6, and the lower surfaces of both sides of the shelf plate 6 are placed on the shelf plate receiving frame members 5 d and 5 d of the shelf plate receiving frame members 5 and 5. A pin having the above bent shape from a pin insertion hole 6, 6 provided in the side end face 6 a to a shelf fixing hole 8 provided in the shelf receiving frame material 5 that matches the pin insertion hole 6, 6. As shown in FIG. 7, the assembly shelf is assembled by fixing the shelf plate 6 by inserting it so that it can be pulled out.

  Specifically, the pin 9 is inserted into the pin insertion hole 6 and the shelf fixing hole 8 from the shaft end portion 9d facing the horizontal direction with the horizontal short shaft portion 9b continuous with the head portion 9a facing downward. Then, the shaft end portion 9d and the inclined shaft portion 9c connected to the shaft short portion 9d are inserted from the pin insertion hole 6 into the shelf fixing hole 8, and the bent portion between the inclined shaft portion 9c and the horizontal short shaft portion 9b is inserted. When the pin reaches the pin insertion hole 6, the bent short part is pushed into the pin insertion hole 6 while the horizontal short shaft portion 9b directed downward is raised in the horizontal direction, thereby the shelf fixing hole from the pin insertion hole 6 8 is inserted. Then, the horizontal short shaft portion 9b of the pin 9 is inserted between the pin insertion hole 6 and the shelf fixing hole 8, and the head portion 9a contacts the inner surface of the side end surface 6a of the shelf plate 6, and The inclined shaft portion 9c hangs downward along the outer surface of the wall surface portion 5a of the shelf board receiving frame member 5 and its shaft end portion 9d is at the lower end of the outer surface of the wall surface portion 5a of the shelf plate receiving frame member 5. It comes into contact.

  Thus, when a heavy article is placed on the shelf board 6 attached between the shelf board receiving frame members 5 and 5 on both sides in a erected state, the shelf board 6 becomes the shelf board support plate of the shelf board receiving frame members 5 and 5. The side end face 6a of the shelf 6 fixed to the shelf receiving frame member 5 by the pin 9 is centered on the projection end of the shelf support plate 5d. As a result, a push-up force is applied to move obliquely upward in a direction away from the shelf receiving frame material 5. This force acts on the head portion 9a of the pin 9 in the direction in which the shaft body portion of the pin 9 is pulled out from the pin insertion hole 6 and the direction in which the head portion 9a is moved upward. The horizontal short shaft portion 9b at the upper end is inserted from the pin insertion hole 6 to the shelf fixing hole 8 and the inclined shaft portion 9c connected to the horizontal short shaft portion 9b is connected to the shelf receiving frame. Since the shaft end portion 9d is suspended downward along the outer surface of the wall surface portion 5a of the material 5 and the lower end portion of the outer surface of the wall surface portion 5a of the shelf plate receiving frame member 5 is contacted, any force is received by the shelf plate receiver. The shaft end portion 9d that is in contact with the outer surface of the wall surface portion 5a of the frame member 5 acts in a direction in which the shaft end portion 9d is further pressed against the wall surface portion 5a to prevent the pins 9 from coming out and the shelf board from being bent downward. Therefore, it is possible to always place a stable article.

  In the above embodiment, the intermediate support column 2 is not necessarily used, and a flat horizontally long rectangular top plate or bottom plate is used instead of the shelf plate 6 on the upper and lower ends of the assembly shelf main body. 4 may be fixed so as to be disassembled in the same manner.
