An adjuster bolt 24 is screwed into this adjuster nut, which prevents displacement in the front-rear direction, up-down direction, and leg plate direction, and whose lower part is in contact with the floor. The adjuster bolt itself is fitted into the narrow groove 22'' of the leg plate 4 so that it is located directly below the leg plate 4.

The lower connecting rod 7, which is attached to the lower part between the pillars 1 and 1 and connects the two branches, has a hook 25 at both ends and a bent edge at the side edge to form a receiving part 28 for supporting the board. In addition, in order to ensure the connection between the lower connecting rod and the column, as shown in FIG. The receiver is connected to the column 1 using a retaining metal fitting 26 having a protruding piece 29 continuously formed on the part, and specifically, the retaining metal fitting 26 is slidably fitted to both ends. The lower connecting rod 7 in the state of
7 is brought into contact with the side surface of the support column 1, and the protrusion piece 29 is fitted into the hole 6 to prevent the hook 25 from coming off from the hole 5. The downward hooks 9 formed on the leg plate 4 described above are fitted into the recesses 9' provided in the uppermost hook 9 to prevent the hooks from moving upward, thereby also preventing the leg plate 4 from slipping out. That's what I do.

The base plate 12 and the kick plate 13 that are attached using the pillar 1, the leg plate 4, and the lower connecting rod 7 constructed in this manner are first attached to the bent horizontal piece 11 of the leg plate 4 by attaching the reinforcing portion 30 provided on the lower surface of the base plate 12. Notch 3 formed on the side edge while being placed on the
1 is fitted and latched to the bent vertical piece 10 of the leg plate 4, and the base end edge 12' is fitted and latched to the part 28 of the retainer 26 of the lower connecting rod 7. At this time, both ends 12'' of the proximal edge 12'' are in contact with the stopper pieces 27 of the retaining fitting 26 of the lower connecting rod 7, so that the board 1
2, the retaining fitting 26 itself can be prevented from coming off.

On the other hand, the kick plate 13 is attached between the front edges of both leg plates by forming a hook 14 on the side plate and fitting the hook into the hook 15 of the leg plate 4, as shown in FIG. The lower surface of the substrate 4 is brought into contact with and supported by the lower surface of the substrate 4.

A reinforcing rod 32 having a desired shape, for example a Z-shape in plan view, is fitted and welded to the inner lower part of the column 1 for reinforcement, and a center panel (not shown in the figure) is attached to the side surface of the column 1 and the upper surface of the lower connecting rod 7. figure)
A concave groove 33 is provided for fitting and mounting, and the bent edge 8 of the leg plate 4 that fits into the notch 1' at the lower end of the column is naturally flush with the lower end surface of the column, and the lower connection As shown in FIG. 1, the rod 7 has a shape in which the lower connecting rod itself has a receiving part 28, and this receiving part is designed so that the side end surface 28' of the part comes into contact with the side surface of the support column 1 to prevent lateral vibration. It may be done.

According to the display stand bottom connection structure of the present invention as described above, the connection between the pillar 1, the most important part of the frame structure of the display stand, the leg plate 4, and the mounting hole 7 can be made strong, so the entire display stand is extremely stable. It becomes what it is.

That is, the connection between the column 1 and the leg plate 4 is achieved not only by fitting the hook 9 and the mounting hole 3, but also by bringing the long piece 17 of the retainer 16, which has been attached to the leg plate 4 in advance, into contact with the front or rear surface of the column 1. It is possible to prevent the leg plate 4 from shaking laterally, and the protrusion 19 formed on the retaining fitting 16 is fitted into the edge of the mounting hole 3 when the hook 9 and the mounting hole 3 are engaged. By latching, the hook 9 can be supported so that it does not come off from the latching with the mounting hole 3, and therefore, even if some external force is applied, the leg plate 4
There is no need to worry about it becoming disconnected from the support column 1.

Note that the lower connecting rod 7 also has its hook 25 and the hole 5 of the support 1.
In addition to the fitting and latching of the hook 25, if the projecting piece 29 of the retainer 26, which is slidably fitted in advance to both ends of the lower connecting rod 7, is fitted into the hole 6 of the column 1, the hook 25 The stopper piece 27 is brought into contact with the side surface of the support 1, which prevents the stopper 26 and the lower connecting rod 7 from wobbling. This can be done reliably.

In addition, the notch 31 provided on the side edge of the base plate 12 attached to the leg plates 4, 4 is fitted and latched to the bent vertical piece 10 of the leg plate 4, and the proximal edge 12' is attached to the retaining metal fitting of the lower connecting rod 7. 26
By fitting and latching the receiver formed on the portion 28, it is possible not only to prevent the receiver from being accidentally pulled out forward, but also to prevent the proximal edge 12 from being pulled out inadvertently.
Since the abutting piece 27 is abutted and supported by both ends 12'' of the ``, it is possible to prevent the retaining fitting 26 itself from coming off.
Also, the adjuster bolt 24 attached to the lower surface of the leg plate 4
By fitting the adjuster nut 23 into the notch 22 provided in the leg plate 4 and screwing it into the adjuster nut, it can be mounted directly below the leg plate 4, thereby ensuring load support.
