CONSTITUTION:In relation to the shelf fixture to fix a shelf board at a specified position of the shelf supports by equipping each of the four corners of the shelf board with receiving metal fittings to put the shelf supports through and providing spacers between such supports and the receiving metal fittings, the shelf fixture is constituted with the inner pipe 3 in the tapering shape at its outer face having the slit 1 and, on its inside, the stopper protrusion 2 to fit in the concave 11 of the shelf support to determine the position and the outer pipe 5 in the upside-down tapering shape at its inner face having the slit 4, and is formed as a pipe in the almost same thickness through its whole length, by uniting said inner pipe 3 and the outer pipe 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a shelf fixing tool for fixing and maintaining a shelf board at an arbitrary position of the pillar when the shelf board of the assembling type shelf is supported by four pillars.

[0002]

2. Description of the Related Art As a means for fixing and maintaining a shelf plate at a predetermined position by brackets at four corners, the bracket has a tapered inner surface that spreads downward (a large diameter is at the bottom), and between the bracket and the pillar. We have proposed a structure in which a spacer with a tapered outer surface is inserted from the lower side to the upper side (small diameter at the upper side).
-30908, Jikkou 3-34114). At this time, the spacer has an inner surface convex portion that fits into a positioning concave portion provided in a column or a prism, and the receiving metal fittings are integrated with the four corners of the shelf plate.

[0003]

The structure proposed above has a structure in which the lower part has a taper inner surface with a large diameter for the purpose of joining the bracket of the shelf to the spacer having a taper outer surface with a small diameter in the upper part. The front and back sides of the shelves supported by the columns were fixed, and only the front side could be used.

Further, in order to process the inner surface into a taper shape in this manner, it is necessary to machine the surface.
It was difficult to manufacture, and it was a factor of cost increase.

According to the present invention, a single shelf can be fixedly supported on both front and back surfaces, for example, a flat type which normally has no edges and which can be used as a tray-like shelf with the edges standing upright when turned upside down. It seeks to provide a shelf fixture that allows the use of both sides of a board.

[0006]

As a result of studying the above-mentioned problems, the present inventor has found that the upper part having a slit 1 and having a locking projection 2 which fits into a positioning recess 11 of a column 10 on the inner surface has a small diameter. The inner cylinder 3 having a tapered outer surface and the outer cylinder 5 having a slit 4 and a tapered inner surface having a large diameter on the lower side are formed, and the inner and outer cylinders 3 and 5 are united to have a substantially uniform wall thickness over the entire length. The shelf fixture 6 in the form of a cylinder was developed.

In this shelf assembling method, first, the inner cylinder is fitted to a predetermined position from the side of the pillar, then the outer cylinder is covered on the inner cylinder, and then the shelf having the mounting holes is installed from above the pillar. Either by assembling through, or by mounting the outer cylinder in the mounting hole in advance and then by inserting through the column to which the inner cylinder is mounted.

When the pillar 10 is a prism having a square cross section, the inner and outer cylinders 3 and 5 referred to here are rectangular frame shapes in cross section, and when the pillar 10 is a cylinder having a round cross section, the inner and outer cylinders 3 and 5 are cross sections. It is ring-shaped.

The slits 1 and 4 of the inner and outer cylinders 3 and 5 are easy to fit when they are expanded downward, but they are not necessarily expanded when the inner and outer cylinders 3 and 5 are made of a soft and easily expandable material.

Further, it is arbitrary whether the outer cylinder 5 is provided with the flange portion 8 below for supporting the shelf board or the protrusion 9 is provided on the outer peripheral surface, and further, both the flange portion 8 and the protrusion 9 are provided. It may be provided.

[0011]

The shelf fixture 6 having the above-described structure has substantially the same diameter over the entire length in the vertical direction.
The mounting holes 14 provided in the bracket 13 have substantially the same diameter in the vertical direction. The shelf plate 12 is supported by the shelf fixture 6 with or without the holding groove 15 provided in the mounting hole 14. Therefore,
The shelf plate 12 can be used on both sides. Further, even when rearranging, the disassembly can be easily performed with a single mallet.

[0012]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a sectional view showing a state in which a shelf is fixed and supported by a shelf fixture of the present invention. FIG. 2 is an exploded perspective view of an embodiment of the shelf fixture. FIG. 3 is an exploded perspective view of another embodiment of the shelf fixture. FIG. 4 is a perspective view of a shelf assembled with the shelf fixture 6 of the present invention.

In the embodiment of the present invention shown in FIGS. 1 and 2, the inner cylinder 3 and the outer cylinder 5 respectively have flange portions 7 and 8 for receiving the load of the shelf plate. The flange portion and the ridges of the outer cylinder mainly serve to position the outer cylinder. However, it also has a function of preventing the shelf plate from slipping out of the outer cylinder when a certain load is applied to the shelf plate. Further, in the example of FIG. 3, there is no flange portion, and the two ridges 9 provided on the outer circumference of the outer cylinder 5 position the shelf plate.

In any of the embodiments, the inner cylinder 3 has a vertical slit 1 which has a wide lower portion which is easily fitted to the pillar, and the inner surface of which the locking projection 2 is fitted to the positioning recess 11 of the pillar 10. The outer surface is tapered so that the diameter becomes smaller toward the top. The outer cylinder 5 also has slits 4, and the inner surface has a structure in which the lower part has a tapered inner surface with a large diameter. Inner cylinder 3
The outer surface taper and the inner surface taper of the outer cylinder 5 are inclined so as to substantially coincide with each other, and when the inner and outer cylinders 3 and 5 are united, the shelf fixture 6 is a cylindrical body having a substantially the same thickness over the entire length. Therefore, the inner surface of the receiving metal fitting 13 into which this is fitted is a right cylindrical surface over the entire length.

In the above structure, the slits 1 and 4 of the inner and outer cylinders 3 and 5 are easily fitted into the pillars when they are expanded downward, so the inner and outer cylinders of FIG. 2 and the inner cylinder of FIG. 3 are expanded downward. However, like the outer cylinder 5 of FIG. 3, when it is made of a soft and easy-to-spread material, it is not always necessary to spread the lower part of the slit 4. Further, the outer cylinder 5 has a flange portion 8 downward as shown in FIG.
It is optional whether to provide the ridge 9 or to provide the protrusion 9 on the outer peripheral surface as shown in FIG. Further, as shown in FIG. 1, both the flange portion 8 and the ridge 9 may be provided.

[0016]

As described above, since the shelf fixture of the present invention is a tubular body having an inner cylinder and an outer cylinder and having substantially the same thickness over the entire length, the same shelf plate can be flattened if necessary. It can be used on both front and back sides of different shelves, such as the front and back sides as a tray with edges. It can be assembled by a knockdown method and the height can be easily adjusted.

If the function of the present invention is utilized, it can be used in many fields such as a cart with wheels attached to the bottom of a workbench or a pillar.
