[Prior art]

 Prefabricated furniture has the advantage of being easy to stock and transport. However, such prefabricated furniture has a fixed shape and volume after assembling, and is not applicable when it does not match the size and shape of the space to be left unattended. Therefore, consumers are demanding combination furniture that can be combined with a suitable shape and volume at any time. In particular, such characteristics are required for racks and shelves.

[0003] Early-designed prefabricated racks had to be screwed together with screw parts when assembled. Tools had to be used to screw in the threaded components, which created the complexity and inconvenience of rack assembly. At present, bamboo knot type pipe racks have already been used in the streets, with metal pipes provided with some annular grooves as pillars, and fitting rings provided at three or four corners of the net shelf on each pillar. It is fixed in a garment and assembled to form an assembled pipe rack 1 as shown in FIG. The assembling type pipe rack 1 shown in FIG. 1 uses the bamboo tube 10 as a support, and as shown in FIGS. It is used as a joining means. This tubular material 10 is provided with several annular grooves 13, which appear to have knots in appearance, and are therefore referred to as bamboo-knotted tubular material 10. The holding piece 11 can be closed and has a tubular shape after the closing, and an inner convex edge 14 is formed at an appropriate position on the inner surface thereof. The outer diameter of the holding piece 11 gradually increases from top to bottom. The inner convex edge 14 of the holding piece 11 fits into any one of the annular grooves 13 of the tubular member 10 and is positioned. Fittings 15 are provided at four corners of the net shelf 12, and the inner diameter of the fittings 15 gradually increases from top to bottom. When the fitting ring 15 of the net shelf 12 is provided on the outside of the holding piece 11 attached to the tubular material 10, the holding piece 11 tightly binds the tubular material 10, and the mesh shelf 12 is fixed.

In the above-mentioned conventional assembling type pipe rack 1, many annular grooves 13 are provided in a bamboo-shape type pipe material 10 serving as a pillar, so that dust easily accumulates and it is difficult to clean the tube rack. Was. In addition, the four (and sometimes more) tubing 10 of the rack after the completion of assembly has a tight annular groove, which may cause visual discomfort. In addition, all the inner walls of the fitting ring 15 provided on the net shelf 12 are in close contact with the outer wall of the holding piece 11, so that the combination between them becomes excessively tight, which makes it extremely difficult to disassemble. Without the method of hitting upward, the fitting wheel 15 of the net shelf 12 and the holding piece 11 could not be separated, which was extremely inconvenient.

【Example】

 As shown in FIGS. 4 and 5, the structure of the assembled pipe rack according to the present invention is composed of some upright pipes 20, some horizontal net shelves 40, and some holding pieces 30. Among them, the holding piece 30 can be stretched and closed and can be closed, becomes a tubular shape after closing, and can be positioned by covering the upright tube. Fitting wheels 41 are provided at each corner of the horizontal net shelf 40, and the fitting wheels 41 can be fixed to the outside of the holding piece 30 attached to the upright tube member 20, whereby the net shelf 40 is positioned. You. The features of the present invention are as follows. That is, horizontal grooves 21 are provided at equal intervals on the back surface of the upright tube 20, and an inner convex pattern 31 is provided on the inner wall of the holding piece 30 so as to correspond to the horizontal groove 21 of the upright tube 20. The holding piece 30 is positioned in the upright tube 20 by fitting the inner convex pattern 31 into the horizontal groove 21 of the upright tube 20. A slope 32 having a small upper part and a large lower part is formed on an outer wall portion on one side of the inner wall of the holding piece 30 where the inner convex pattern 31 is provided, and is attached to the slope 32 of the outer wall of the holding piece 30 of the fitting wheel 41 of the net shelf 40. A slope 42 is formed corresponding to the portion where they meet. See also FIG. Due to the suppression and restraint action generated on the slope 32 of the holding piece 30 of the slope 42 of the fitting wheel 41 of the net shelf 40, the inner convex pattern 31 on the inner wall of the holding piece 30 is further formed in the horizontal groove 21 of the upright pipe 20. And the fitting wheel 41 of the net shelf 40 is fixed, so that the operation of fixing the net shelf is achieved.

The above-described upright tubing 20 preferably has a non-circular cross-section, which facilitates assembly because the components can be combined with a directional shape. To give an example of an upright tube 20 having an elliptical cross section, its horizontal groove 21 is provided in a slightly longer surface of one of its widths and the other surface is light-smooth, so that it is easy to clean. The appearance also improves. When the upright tube 20 having a non-circular cross section is used, the direction of the horizontal groove 21 of the upright tube 20 can be easily determined at the time of assembly, and the positioning of the holding piece 30 in the upright tube 20 is directional and non-rotatable. This is convenient for assembly. In principle, the position of the horizontal groove 21 of the upright tubing material 20 is a position that cannot be seen by the consumer, and therefore, it is preferable that the horizontal groove 21 is provided on the back surface of the upright tubing material 20 so that the front surface visible to the consumer can be obtained. Both are light smooth surfaces.

As shown in FIGS. 7 and 8, the outer wall of the above-described holding piece 30 has a slope 32 with a slightly smaller local portion and a larger lower portion, and the other portion has a straight cylindrical shape. The position is the outer wall of a part of the inner convex pattern 31, so that when the slope 32 is pressed, the inner convex pattern 31 fits more tightly into the horizontal groove 21 of the upright pipe member 20, and a good position is obtained. The placement effect is achieved. The inner wall of the fitting wheel 41 corresponding to the holding piece 30 of the net shelf 40 is also formed with a slightly inclined surface 42 at the local portion, and the other is formed in a straight cylindrical shape, and is combined with the shape of the holding piece 30. When the fitting wheel 41 of the net shelf 40 is put on the outside of the holding piece 30, the action of slightly suppressing and restraining the slope 32 of the slope 42 occurs, and the other is a straight cylindrical portion and does not generate the suppression action. Therefore, the holding piece 30 has a function of preventing the net shelf 40 from falling off, but the degree of tension during that time is not excessive, which is convenient for disassembly work at a later date. Therefore, the fitting portion of the fitting ring 41 of the net shelf 40, the upright tube member 20, and the holding piece 30 has a vertical appearance on both the front surface and both side surfaces, and exhibits a good appearance. This is as shown in FIGS.

FIG. 9 is a plan view of a combination of an upright tubular member 20 ′ having an oblong cross section and a holding piece 30 ′. FIG. 10 is a sectional view taken along line 10-10 of FIG. A horizontal groove (not shown in the figure) is provided on the back surface of the upright pipe member 20 ', the outer wall of the holding piece 30' is slightly inclined on the back surface 32 ', and both ends of the front surface are formed. A slightly protruding projection 33 'is formed to prevent the holding piece 30' and the fitting wheel 41 of the net shelf (not shown) from swinging left and right after being engaged.

[0014]

[Effect of the invention]

 The design of the present invention has the following advantages in use. 1. Since the front of the upright tubing 20 is a light smooth surface and the appearance seen by a person is a light smooth surface without the horizontal groove 21, it is visually more comfortable and beautiful, and enhances the purchase motivation of consumers. 2. The inclined surface 42 of the inner wall of the fitting ring 41 of the net shelf 40 restrains the inclined surface 32 of the outer wall of the holding piece 30, and the holding piece 30 acts to prevent the net shelf 40 from falling off, but the tightening degree therebetween is excessive. It is convenient and easy to disassemble. 3. In a preferred embodiment in which the upright tubing 20 is a non-circular tubing, the direction of the horizontal groove 21 of the tubing 20 can be easily determined, and the holding piece 30 can be positioned in the upright tubing 20 in an accurate direction, which is advantageous for assembly. 4. The upright tube 20 is easily wiped and cleaned, and dust hardly accumulates.

In summary, the structure of the assembling pipe rack provided by the present invention can be said to be a kind of ideal design, which is easy to assemble and disassemble, and is comfortable and beautiful in appearance.
