Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a shelf board for a pipe shelf, and particularly relates to a connecting structure at the end thereof.

[Conventional technology and its problems]

Conventional pipe shelves have a structure in which pipes are arranged on receiving metal fittings that are engaged with the shelf frame, held down by corrugated holding metal fittings, and both metal fittings are fixed with screws. Things were normal.
(For example, see Utility Model Publication No. 52-27098.) However, with this structure, it is necessary to tighten a large number of screws during the manufacturing process, which is inefficient, and the screws and nuts are exposed, which impairs the aesthetic appearance. In addition to chipping, it also caused injuries to hands and other parts. In order to solve such problems,
There is also a cover that covers the outside of the receiving metal fitting and the holding metal fitting (Japanese Utility Model Publication No. 56-41553), but this is the same as the conventional one in that it is fixed with a large number of screws.

Furthermore, as a simple means for fixing pipes, the equivalent of a receiving metal fitting is made of plastic, and the end of the pipe is press-fitted into this, but plastic alone is not strong enough to support the load on the shelf. There are some shortcomings.

In view of the problems of the prior art as described above, the purpose of this invention is to provide a shelf board that has a simple method for fixing pipes, has a good appearance, and has sufficient strength.

[Means for solving problems]

In order to solve the above problems, this invention has been proposed for a pipe shelf in which multiple pipes are arranged in parallel and both ends are connected and integrated by horizontal bars, and the horizontal bars are made of plastic. Consisting of a combination of a connecting member and a metal reinforcing metal fitting, the connecting member is provided with a plurality of pipe insertion holes, and the metal reinforcing metal fitting is formed into a U-shaped cross section that fits on both the upper and lower surfaces and the outer surface of the connecting member. Then, screws are screwed into at least two pipe insertion holes from the bottom surface of the reinforcing metal fitting to integrate the pipe, the connecting member, and the reinforcing metal fitting.

〔Example〕

Figure 1 shows a shelf board showing an embodiment of this invention.
A plurality of pipes 1 are arranged in parallel, and both ends thereof are connected by horizontal bars 2.

As shown in FIGS. 2 and 3, the horizontal beam 2 is constructed by a combination of a plastic connecting member 3 and an aluminum reinforcing metal fitting 4.

The connecting member 3 has a number of pipe insertion holes 5 corresponding to the number of pipes 1, and two vertical positioning holes 6 are formed at appropriate positions between the pipe insertion holes 5. These pipe insertion holes 5 and positioning holes 6 are formed in the horizontal cylindrical portion 7 and the vertical cylindrical portion 8, respectively, and these cylindrical portions 7 and 8 are connected to a horizontal connecting plate 9 and an inner plate 10 integral therewith. Outer plate 1
1, and the above-mentioned connecting plate 9
A closing plate 12 is integrally provided at both ends of the inner and outer side plates 10 and 11, respectively.

Further, the aluminum reinforcing metal fitting 4 has a U-shape that fits into both the upper and lower surfaces of the connecting member 3 and the inner and outer side plates 10 and 11, and has engaging edges 13 formed on the upper and lower edges of the inner plate 10. It is. This engaging edge 13 is engaged with a step 14 formed on the connecting member 3. Further, a hole 15 (see FIG. 3) that coincides with the positioning hole 6 is provided on the lower surface of the reinforcing metal fitting 4. Furthermore, the pipe 1 at both ends
In the portion of the cylindrical portion 7 into which the reinforcing metal fitting 4 is inserted, a screw 16 reaching the pipe 1 from the lower surface of the reinforcing metal fitting 4 is screwed in to integrate the pipe 1, the connecting member 3, and the reinforcing metal fitting 4.

Since the horizontal beam 2 has the above-mentioned configuration, it is formed into a rectangular column shape as a whole, and the upper, lower and outer surfaces are surrounded by aluminum reinforcing metal fittings 4, and the plastic of the connecting member 3 is exposed on the inner surface and both end surfaces. The pipe 1 is inserted into the inner surface thereof.

The shelf frame 17 that supports the shelf boards connected and integrated by the horizontal beams 2 described above has a positioning protrusion 19 protruding from a receiver 18, as shown in FIGS. 2 and 3. As shown in FIG. 3, this protrusion 19 is made by screwing a screw into the holder 18 and protruding from the upper surface.
Alternatively, as shown in FIG. 5, a rivet may be inserted from the lower surface of the receiver 18 and then welded together.

In either case, it is desirable to form a small recess 20 on the upper surface of the receiver 18 to receive the head of the screw 16.

The shelf board according to this invention is assembled to a shelf frame 17 by inserting the projections 19 into the holes 15 and 6 provided on the lower surface of the horizontal bar 2. In addition to being used in combination with the shelf frame 17, the shelf board of this invention may be used alone as a shelf board by placing both ends on appropriate supporting members. In that case, the positioning hole 6 is unnecessary and is therefore omitted.

〔effect〕

As described above, the shelf board of this invention is constructed by combining horizontal bars made by connecting and integrating both ends of pipes with plastic connecting members and metal reinforcing metal fittings, and the upper and lower parts are connected by the reinforcing metal fittings. By forming the outer surface and the inner surface and both end surfaces by the connecting member, the horizontal beam is formed into a prismatic shape as a whole.

Therefore, the appearance of the horizontal bar portion is much sleeker than that of the conventional one, and not only does it have a good appearance, but there is no need to worry about getting your hands or fingers caught on it.

Furthermore, in manufacturing, only two screws are used for each horizontal beam in order to integrate the connecting member, auxiliary fittings, and pipes, and all others have a mating structure, which improves manufacturing efficiency. .
