By doing this, when the bottom plate 3 tries to tilt forward and downward due to a load applied to the front, the metal fittings 19 will receive the tilting force in the forward tilting direction and be pried at the metal fitting insertion holes 13 and 18. Since the resistance force is exerted, the above-mentioned tilt prevention effect of the bottom plate 7 can be obtained.

By the way, when the depth dimension of the bottom plate 7 is larger than that shown in FIG. 4, as shown in FIG.
The rear engaging portion 17b of the engaging claw 17...
. . . is engaged with the engagement hole 12 .

By doing this, the member 15 moves forward and the length of the leg 5 protruding forward with respect to the column 1 becomes longer, so that the bottom plate 7
The base area can be increased correspondingly to ′.

Further, as the leg 5 moves forward, the rear metal fittings 19 and 19 are set in the opposite direction to that shown in FIGS. 3 and 4, so that the metal fitting head 20 is moved substantially backward Hezrasu.

In addition, in the case of the display shelf of this embodiment, the back panel 2 is the pillar 1,
The bottom plate 7 is attached to the base B with its rear end surface in contact with the front surface of the back panel 2.

However, in the case of a so-called open-type display shelf that does not have such a back panel 2, or a so-called single-panel type display shelf that has one back panel installed between the opposing inner surfaces of the vertical columns 1, 1. If the bottom plate is attached in the same manner as described above, a gap will be created between the front end of the bottom plate 7 and the support column 1, which is not preferable in terms of appearance.

Therefore, in such a case, each mounting bracket 19...
Contrary to the case of the above embodiment, the head 20 is attached with the side where the head 20 largely protrudes from the body 21 facing backward.

By doing this, each metal fitting head 20 is moved backward uniformly, so the bottom plate 7 is retracted backward,
After that, it is attached with the end surface in contact with the pillars 1, 1).

On the other hand, as shown in FIG. 7, the floor surface F is inclined, and the legs 5
If the height adjustment cannot be covered completely by the adjuster 10.10, the engaging claw 16 provided at a high level on the mounting member 15 should be inserted into the engaging hole 12... engage.

In this way, the height position of the member 15, that is, the height position of the legs 5 is lowered, and the inclination of the floor surface F can be sufficiently absorbed.

Note that the present invention is not limited to the above-mentioned embodiments, and for example, the engaging claws of the leg attachment member need not necessarily be provided on both the front and rear sides of the member as in the above-mentioned embodiments, but may be provided only on the rear side.

Further, the number of engagement holes in the engagement pawl and the support column is not limited to four, but may be provided at least on the negative side.

Furthermore, the metal fitting insertion hole of the leg may be provided only on the upper surface of the leg.

The present invention is applicable not only to the wall-fixed type display shelves mentioned in the above embodiments but also to floor-mounted type display shelves.

As described above, according to the present invention, the legs can be attached to the support very simply and firmly, and can be easily removed.

Therefore, the display shelf can be assembled and disassembled efficiently, and it is convenient to transport, store, etc. in the disassembled state.

In addition, since the legs are attached to the struts via the leg attachment members and connecting metal fittings, (i) instead of connecting the engagement claws directly to the legs, it is possible to attach them to the leg attachment members separate from the legs. Since the engaging pawl is provided and the member is fitted into the swollen diameter end and connected by a connecting fitting, the swollen end has a double structure.

Therefore, this portion exhibits a high resistance against the vertical load applied to the expanded diameter end portion.

Further, since the load applied to the engagement portion of the engagement claw with the leg is supported by the double structure portion, the load burden on the engagement portion is reduced.

These points make it possible to increase the load bearing capacity of the leg attachment portion.

In addition, the connecting fittings can also be used as bottom plate supporting fittings, and the position of supporting the bottom plate by the fittings can be changed depending on the size of the bottom plate, making it convenient for attaching the bottom plate.
