Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shelf structure such as an OA equipment mounting table and a wagon table.

[0002]

[Prior art]

 As a shelf structure of this type, there is one having a plurality of (for example, four) columns and a shelf horizontally held by the columns.

By the way, in the case of holding a shelf on a pillar, conventionally, for example, a method of providing a locking piece on the pillar and locking the shelf on the locking piece, or a method of fixing the shelf and the pillar by welding or the like And so on.

[0004]

[Problems to be solved by the device]

 However, in the case of the one with the locking piece, the holding state of the shelf is unstable and it is easy to rattle, and in the case of welding, the position of the shelf cannot be changed or disassembled, which is inconvenient. there were.

Therefore, an object of the present invention is to provide a shelf structure in which the shelf can be securely held horizontally without rattling and the shelf can be attached and detached.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a shelf structure according to the present invention is a shelf structure including a plurality of pillars having a circular outer surface and a shelf horizontally held by the pillars. The corner of the shelf is provided with a corner wall having a substantially semicircular cross section whose outer surface has a radius of curvature smaller than that of the outer peripheral surface of the column, and the inner surface is fitted with the column fitted from the outside. Only the both end portions of the column form a recess that abuts the outer peripheral surface of the column, and the column fitted into the column is screwed to the column from the inside through the corner wall to the inner surface of the column. The shelf and the column are connected by a screw member that presses both ends of the column to the outer peripheral surface of the column.

[0007]

[Action]

 When the pillar is fitted in the recess of the shelf, only the both ends of the inner surface of the recess contact the outer surface of the pillar. In this state, if the screw member is screwed onto the pillar, the corner wall is pressed toward the pillar by the screw member, and both ends of the inner surface of the recess are pressed against the outer peripheral surface of the pillar.

That is, since the column is pressed against the column at two places, the shelf is held by the column without rattling.

[0009]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the drawings illustrating an embodiment.

FIG. 2 shows a shelf structure according to the present invention. The shelf structure includes a plurality of (four in the illustrated example) pillars 1 ... And a shelf 2 horizontally held by the pillars 1. (3 sheets in the illustrated example).

The pillar 1 is composed of a circular pipe whose outer surface is circular, and a caster 3 is attached to the lower end thereof. A cap is attached to the upper end of the pillar 1.

Thus, the shelf 2 is formed of a rectangular flat plate having an upper wall 2a and a side wall 2b, and a corner portion 4 thereof has a corner wall 4 having a substantially semicircular cross section, as shown in FIG. It is provided, thereby forming a recess 5 into which the post 1 fits.

As shown in FIG. 3, the corner wall 4 has a state in which the radius R of curvature of the outer surface 4 a is set smaller than the radius R ₁ of the outer peripheral surface 6 of the column 1 and the column 1 is fitted in the recess 5. Then, only both ends 7a, 7a of the inner surface 7 of the recess 5 contact the outer peripheral surface 6 of the column 1. That is, the central portion 7b of the inner surface 7 of the recess 5 does not contact the outer peripheral surface 6 of the column 1.

Further, a through hole 8 is provided in the central portion of the corner wall 4, and a screw hole 9 is provided in the pillar 1.

Then, the screw shaft 10 a of the screw member 10 is screwed into the screw hole 9 of the pillar 1 from the inside through the through hole 8 of the corner wall 4.

At this time, if the screw shaft 10a of the screw member 10 is advanced, the head portion 10b of the screw member 10 presses the corner wall 4 in the direction of arrow A as shown in FIG. Both ends 7a, 7a of the inner surface 7 of 5 are pressed as indicated by arrows B, B and are pressed against the outer peripheral surface 6 of the column 1.

Therefore, the shelf 2 is securely held by the four pillars 1 in each corner portion C without being wobbled or wobbled because two places are pressed against the outer peripheral surface 6 of the pillar 1. It That is, the shelf 2 can be held in a stable posture by only screwing one screw member 10 at each corner C.

The present invention is not limited to the above-described embodiment, and the design can be freely changed without departing from the gist of the present invention. For example, if each column 1 is provided with a plurality of recesses 5, the shelf 2 The upper and lower positions can be changed, and the number of shelves can be increased or decreased and the space between the upper and lower shelves 2, 2 can be freely adjusted.

Also, the pillar 1 may be a solid cylindrical body instead of a pipe material, and the length and outer diameter of the pillar 1 may be freely changed. The length and width of the shelf 2 can be freely changed.

[0020]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

At each corner C of the shelf 2, only by screwing one screw member 10 to the pillar 1, the shelf 2 can be held in a stable state without rattling or wobbling. .

Further, if the screw member 10 is unscrewed and removed from the column 1, the shelf 2 can be removed from the column 1, so that the shelf structure can be easily assembled and disassembled.

Furthermore, it is possible to easily change the vertical position of the shelves 2 and increase or decrease the number of shelves 2.
