0, and each stage is disassembled into a loading platform 2A-2C. Then, as shown in FIG. 2A, each of the side frames 1A and 1B connects the connecting member 8 and each of the columns 6 and 7 with a joint (rivet) 14 thereof.
, The front support 6 and the rear support 7 are overlapped with each other so that the oblique connecting member 8 is sandwiched between the front support 6 and the rear support 7 to reduce the bulk. be able to. At this time, most of the connecting member 8 enters the inside of each of the front and rear columns 6 and 7. When assembling, a left-right connecting member 9 is erected between the upper ends of the front posts 6 of the left and right frames 1A, 1B, and a left-right connecting member 10 is erected between the lower ends of the rear posts 7. 8 and each of the struts 6, 7 are relatively swung in the opening direction around the joint (rivet) 14 so that a predetermined interval is provided between the front and rear struts 6, 7 so that the rear strut 7 is placed on the floor surface. Install on the floor so that it stands upright. In this state, the bed 2A of each stage
2C is installed between the left and right side frames 1A and 1B.
The height and inclination angle of the loading platforms 2A to 2C of each stage are the loading platforms 2A for the front and rear columns 6, 7 in the left and right side frames 1A, 1B.
2C can be freely set by changing the mounting position up and down by selecting the square hole 13 of each of the columns 6 and 7.

In the assembled shelves (flow shelves) having the above-described configuration, the inclined upper end portions (the loading platforms 2A to 2C) of the loading supports 2A to 2C of each stage are provided for each of the load supporting rows composed of a pair of left and right roller rails 4a and 4b. Each load slides on the roller rails 4a and 4b by placing the load on the
In a state in which the leading load is received by the stopper 5 at the lower end of the slope, the load stays so as to be connected to the rear and is stored. Then, by picking up the top load from the front ends of the loading platforms 2A to 2C in each stage, the subsequent loads are loaded on the roller rails 4a,
4b, the leading load is again received by the stopper 5, and the subsequent load is connected to the stopper.

It should be noted that one or both of the left and right connecting members 9 and 10 may be attached if necessary, and are not essential. When attaching the left and right connecting members 9 and 10, the left and right connecting members 9 and 1 for the columns 6 and 7 are also used.
The mounting structure of No. 0 is not limited to the configuration of the above embodiment.
As the loading platforms 2A to 2C, a fluid type loading platform having the roller rails 4a and 4b is illustrated, but a general horizontal loading platform may be used, and the structure of the loading platform is not limited.
In addition, the loading platforms 2A to 2 are arranged in three stages between the left and right side frames 1A and 1B.
Although C is installed, the number of stages of the loading platform may be any number as long as it is two or more. Further, the diagonal connecting member 8 is connected to the front support 6.
May be provided between the position near the lower end of the rear support 7 and the position near the upper end of the rear column 7.

[0021]

As described above, according to the shelf of the present invention, the left and right frames supporting the upper and lower stages of the loading platform have the front support and the rear support, and the positions near the upper and lower ends of the front support and the opposite of the rear support. Since it is composed of only three members of the diagonal connecting member that connects the position near one end of the side, the entire shelf is compared with the shelf using the conventional side frame composed of the rectangular frame and the diagonal reinforcing material. The number of parts is reduced, which contributes to a reduction in material costs and assembly costs and a reduction in shelf weight. Moreover, by combining the upper and lower loading platforms and the front and rear supports of the left and right frames,
Since the loading platform itself of each stage is also used as the strength member of the side frame, even if this connection is a simple uniaxial connection, sufficient strength can be provided to the entire shelf.

According to the second aspect of the present invention, the loading racks of the respective stages are arranged such that the load loaded from the rear end flows forward to the front end side. When a load is loaded on the inclined upper end portion (rear end portion), a tensile force acts on the diagonal connecting member via the rear support of the left and right frames, and a compressive force acts on the connecting member. In comparison with the case where the connecting member is used in an inclined direction, a thin and lightweight mold member having relatively small bending strength (buckling strength) can be used for the oblique connecting member.

According to the third aspect of the present invention, not only can the strength of the entire shelf be increased by the left-right connecting members between the upper ends of the front pillars, but also the left-right connecting members can be placed on the loading platform. It can be used as a display surface for displaying the position in the left-right direction, the type of load, and the like, and a display plate mounting surface.

Further, according to the structure of the fourth aspect,
With the left-right connecting material installed between the lower ends of the rear columns of the left and right frames, the strength of the entire shelf can be increased,
In particular, in the case of the fluidized shelf as shown in the embodiment, the rear end side of the lowermost loading platform is high, and by utilizing the space under that, the left and right connecting members are erected between the lower ends of the rear columns. Therefore, it is not necessary to secure a special space for erection of the left and right connecting members for increasing the strength of the shelf, and it is not necessary to particularly lengthen the columns.

Further, according to the configuration of the fifth aspect, before assembling the shelves, the left and right side frames can be folded so that the connecting member is sandwiched between the front support and the rear support to reduce the bulk. It is convenient for storage and transportation. In this case, according to the configuration of the sixth aspect, when the side frame is folded, the connecting material enters inside the front and rear struts, so that the bulk can be further reduced.
