In such a shelf, a base frame is provided at a lower portion between side plates standing upright at a predetermined interval, and a flat table and a flat table top plate provided with a predetermined drawer at the upper portion of the base frame are provided. The structure is adopted, and the upper area supports a plurality of shelves.

8 and 9 show a conventional base structure in a display rack for books. In these figures, the shelves 100 include a plurality of base frames 1 arranged in a row in a horizontal direction so as to be adjacent to each other.
01, side plates 102 that are erected on both sides of these base frames 101 and that are connected to the base frames 101 by appropriate bolts, and a back panel 103 supported between the rear portions of the side plates 102. A flat base 106 arranged on the base frame 101 and provided with a drawer 105 that can be taken in and out;
6 and a flat base top plate 107 arranged on the upper side of the base plate 6.

The base frame 101 has a substantially rectangular shape with a space defined in an inner area.
The adjusters 108 for adjusting the height positions with respect to the installation surface S are provided on the lower surfaces of the four corners of 01, respectively. Further, adjusters 109 similar to those of the base frame 101 are provided on the lower end surface of the side plate 102 at front and rear positions, respectively.

The flat base 106 and the flat base top plate 107 are configured to be connected to each other using bolts (not shown), and the side plates 102 on the flat base top plate 107,
A plurality of shelves (not shown) are arranged between 102.

[0006]

However, in such a conventional structure, as shown in FIG. 9, there is a gap corresponding to the thickness d of the side plate 102 between each base frame 101. However, there is a problem in that this does not always give a continuous feeling, and it is not always possible to secure a good appearance when viewed as a whole.
In this case, if the frame portion located on the front side of each base frame 101 is set to have a length such that its surface is flush, the above-mentioned inconvenience can be improved.
As long as the adjuster 109 is provided on the lower end surface of the
Such a configuration cannot be adopted. That is, when the front side of each base frame 101 is formed into a series of shapes, it becomes difficult to access the adjuster 109 of the side plate 102 located between the base frames 101 with a spanner or the like, and as a result, the height of the side plate 102 is increased. This is because the position cannot be adjusted.

Further, the base frame 101 and the flat base 1
Since the connection with 06 and the connection between the flat base 106 and the flat base 107 are performed by using bolts, the connection work by bolts cannot be performed unless the drawer 105 is removed. There is also an inconvenience that workability is poor because a quick assembly work cannot be performed, for example, a drawer must be set after the work is completed.

After the connection between 6 and the flat base 17 is completed, a predetermined shelf plate or the like (not shown) is hung above the side plates 16 to complete the assembly of the shelf 10 as a whole. As shown in FIG. 7, there is no gap between the front frames 20 of the base frame 11 in the assembled state.

After the above-mentioned assembly is completed, or when it becomes necessary to adjust the height position during the assembly work, the screw shaft 31B of the adjuster 31 is moved back and forth in the axial direction to move the head 31A. It can be performed without difficulty by adjusting the height position.

Therefore, according to the above-described embodiment of the present invention, the front frames 20 of the respective base frames 11 are continuously exposed in a horizontal row in a state where the base frames 11 are aligned in a horizontal row on the installation surface S. With this configuration, it is possible to completely clean the gap that appears in the conventional base structure, and there is an effect that the appearance can be favorably improved. Further, since the side plates 12 between the base frames 11 can be mounted by using the upper surface of the protruding portion 23A formed on the connecting frame 23 of the base frame 11 as a mounting surface, an adjuster is provided at the lower end of the side plates 12. There is no need, and the adjusters 3 are simply arranged at the four corners of the base frame 11.
The height position can be adjusted by just adjusting 1.
It is possible to realize a quick assembly work.

Further, the front frame 20 is continuous in a plane,
Since no gap is exposed, it is possible to avoid the accumulation of dust in the gap, which is seen when there is a gap.

Further, since the connection between the base frame 11 and the flat base 16 and the connection between the flat base 16 and the flat base 17 are carried out by engaging each other, a plurality of bolts as in the prior art are adopted. Compared with the structure in which the components are connected to each other by using, the number of assembling steps can be reduced, and as a result, the assembling work as a whole can be simplified. At this time, since the hook piece 26 for engaging the bottom plate 40 of the flat base 16 is formed integrally with the support groove 35 which has been conventionally used, the hook piece 26 is engaged only by slightly changing the shape. It can be used as a means, and there is no fear of increasing the product cost or the like.

Further, in the conventional structure, it is inevitable to remove the drawer and set the drawer after the above-mentioned connecting work, whereas in the present embodiment, the drawer 15 is placed in the flat stand 16. It is possible to perform the above-mentioned assembly with the housing accommodated, and it is possible to improve workability. Moreover, depending on the case, the drawer 15
It is also possible to connect the flat base 16 and the flat base top plate 17 in advance while accommodating them and to engage them with the base frame 11 as a unit. In particular, in this working mode, since the number of times the flat base 16 and the flat base top plate 17 are accessed between the side plates 12 can be reduced, the occurrence rate of damage to the side plates 12 or the like due to contact between the respective components during work can be reduced. Can be effectively reduced, and workability can be improved also from this point.

The engaging structure between the base frame 11 and the flat base 16 in the above-described embodiment has a hook piece 26 provided on the upper portion of the back frame 21 forming a part of the base frame 11, and the hook piece 26. Although it has been illustrated and described as being based on the rear end side of the bottom plate 40 which is fitted, the present invention is not limited to this, and other engagement structures can be substituted. For example, the engaging structure of the flat stand 16 and the flat stand top plate 17 shown in the above embodiment may be adopted. Further, the hook piece 26 may be formed in a partially elongated form instead of the elongated type so that the same action and effect can be obtained.

Further, in the above-mentioned embodiment, the lower portion of the side plate 12 and the connecting frame 23 are connected by bolts or the like. However, the portion connecting the lower end of the side plate 12 between the connecting frame 23 is not bolted. It does not have to be done.
According to this configuration, further simplification of assembly will be realized.

Further, the adjusters 31 are not limited to the case where they are arranged at the four corners of the base frame 11, but it is conceivable to reduce the number of adjusters installed by three-point arrangement or the like if a certain level of levelness with respect to the installation surface S can be secured.
