DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a furniture column for supporting a shelf board such as a display shelf used in a store or the like.

[0002]

2. Description of the Related Art Conventionally, as a display shelf used in a store or the like, for example, two projections, such as dowels, are provided at the same height in the depth direction on each of opposing surfaces of side plates arranged opposite to each other. It is known that a shelf board is placed on the shelf and fixed to prevent a fall. Usually, such shelves are provided in a plurality of stages to form one display shelf. In such a configuration, each shelf is supported so as not to move at four points in order to prevent falling.

[0003]

However, in the above-mentioned structure, since the shelf board can be supported at four points, if the shelf board is warped, the shelf board is not attached to the projection. When placed on the shelf, the shelf may be supported at three points and rattle. In order to prevent such rattling, 4
When the point supporting portions are forcibly brought into contact with each other and fixed, an excessive force is applied to the shelf plate, and a large stress remains inside the shelf plate, so that problems in strength and durability are likely to occur.

An object of the present invention is to solve such a problem.

[0005]

In order to achieve the above object, the present invention takes the following measures. That is, the furniture pillar according to the present invention includes four pillars and connecting means for interconnecting the four pillars in a state where the four pillars are arranged at the corners of the square, and one pillar is formed by: A base,
A mandrel that is detachably erected at the center of the upper surface of the base, and at least two line members that are arranged in plane symmetry with respect to the axis of the mandrel, and have free ends that face each other at a predetermined distance, And a plurality of annular line members in which portions other than the free ends are fixed to the respective line members at regular intervals and at a distance corresponding to at least the thickness of the shelf plate in parallel with the upper surface of the base, and an uppermost annular line A connecting member for connecting the two pillars with the free ends of the ring members facing each other, and connecting the pair of the connected two pillars; It is characterized by becoming.

[0006] As the connecting means, a female screw member fixed to the annular wire member, a male screw member screwed with the female screw member,
A first connecting member fixed at each end to a separate pillar by screwing a female screw member and a male screw member, and a second connecting member connecting the first connecting members to each other, Good. Further, it may be constituted by a shelf plate and a fixture for fixing the shelf plate to the ring member. Furthermore, you may comprise with a desk top plate. When a desk top plate is used, the present invention functions as a desk.

[0007]

With this structure, the annular wire member on which the shelf board is to be placed is symmetrically arranged two by two with respect to the axis of the mandrel that is detachably provided on the base. The free end is fixed to the arranged wire member without being fixed. Since the free ends are opposed to each other in the two pillars, they exist inside the space between the pillars. Therefore,
When the shelf is placed on the ring member, the shelf is supported at the free end of the ring member. Since the free end is not fixed to the wire member, the shelf is supported by a substantially elastic portion. In other words, the free ends individually tend to elastically deform and come into elastic contact with the shelves. Therefore, as in the case where four points of the shelf board can be supported by rigid protrusions and claws,
It is difficult to cause a phenomenon that only one point rises and the shelf plate rattles. In addition, since each free end is individually elastically deformed, even if four points of the shelf are forcibly coupled to these free ends, it is possible to suppress an excessive force from being applied to the shelf. Further, if the shelf is elastically held by the free end of the annular wire member as in the present invention, it is possible to softly receive an impact load acting on the shelf during loading or the like.

[0008]

An embodiment of the present invention will be described below with reference to the drawings.

The base 8 has an upper surface 8a which is a plane for mounting the mandrel 9 by cutting off the apex of the pyramid, and a mounting hole for inserting the bolt 6 for the mandrel 9 into the upper surface 8a. 7, and a peripheral portion slightly above the bottom surface of the quadrangular pyramid is cut out to form an upper surface step 8b. The mandrel 9 is made of a round pipe material, a bolt for attaching the fixing member 12 is fixed to an upper end, and a bolt 9 is fixed to a lower end.
The nut corresponding to is fixed. The fixing member 12 is
The cross-sectional shape is substantially trapezoidal, and the lower surface is provided with a groove 12a that engages with the annular wire member 11.

In this embodiment, two wire members 10 are paired. In this wire member 10, an annular wire member 11 is provided with a side H1 having a free end 11a and a side H2 facing the side H1. And the inner surfaces of the remaining two sides H3 and H4 are fixed by welding. When viewed from the annular line member 11, the line member 10 is a distance L1 between the side H1 and the line member 10a.
Is fixed at a position where the distance L2 between the side H2 and the wire member 10b is shorter. Since the annular wire member 11 is thus welded to the wire member 10, the free end 11a of the annular wire member 11 has elasticity. The upper end of the wire member 10 is spherically finished. The wire rod 13 formed by the wire member 10 and the annular wire member 11 is placed on the upper surface step 8b of the base 8, and the fixing member 12 attached to the mandrel 9 is the uppermost annular wire. By fixing the member 11, it is fixed on the base 8.

In the vicinity of the lower end of the wire rod 13, a female screw member 14 constituting the connecting means 5 is welded to the inner surface of the annular wire member 11. The internal thread member 14 is connected to the annular line member 11.
The female screw holes 14a are cut in two places near the upper end of the sheet metal slightly wider than the interval between the free ends 11a. A bolt 16 which is a male screw member inserted into a hole 15a provided at an end of the first connecting member 15 constituting the connecting means 5 is screwed into the female screw hole 14a. First connecting member 15
Is formed by welding a channel material 15b having holes 15a drilled at both ends of a square pipe material, and connecting the two pillars 2 by fixing the channel material 15b to the female screw member 14. The pair of the two connected pillars 4 is connected by a second connecting member 17 by a bolt substantially at the center of the first connecting member 15. Like the first connecting member 15, the second connecting member 17 is also formed of a square pipe material, and nuts are embedded at both ends.
