Description

[Detailed Description of the Invention] This invention relates to a support pipe fixing fitting used for horizontally attaching a pipe to a support in a bicycle road prevention rack or the like.

For example, a bicycle road prevention shelf usually consists of a pipe fixed horizontally between the supports with pipe fixing fittings, but the pipe fixing fittings do not have bolt heads or legs that protrude toward the bicycle road side. It is necessary to create a structure that does not

For this reason, the pipe fixing fitting has a structure in which the pipe is calibrated with a jaw fitting, and the base of this jaw fitting is fixed to a support.

As a result, the amount of pipe L coming out from the support column becomes large, and in snowy areas, the pipe fixing fittings may be bent by the weight of the snow accumulated on the jaw fittings and the pipe, leading to damage.

From the above-mentioned viewpoints, this invention provides a support pipe fixing fitting that has a structure that can withstand large loads from above. A jaw fitting that allows the end of the pipe to be horizontally calibrated is fixed to the front upper part of the plate, a gusset retainer is fixed between the lower jaw fitting of the jaw fitting and the front lower part of the back plate, and a gusset retainer is fixed to the front lower part of the back plate. The plate is characterized in that a bolt insertion hole passing through the base of the jaw fitting is bored in the upper part of the plate.

This invention will be explained by way of examples with reference to the drawings.

FIG. 1 is a side view of a support pipe fixing fitting according to an embodiment of this invention, and FIG. 2 is a plan view thereof.

As shown in the figure, the support pipe fixing fitting of this invention has two base parts of the jaw fitting 20 welded to the upper front surface of the back plate 1, and the bottom surface of the lower jaw part 2B of the jaw fitting 2 and the front side of the back plate 1. There is a gusset retainer 3 to secure it between the lower part and the lower part.

As shown in FIGS. 3 and 4, the back plate 1 has a back surface 1a formed into a concave curved surface that closely contacts the outer surface of the support column 4. As shown in FIGS.

The jaw fitting 2 is attached to the top and bottom of the base of the two people.
is formed to be smaller than the outer diameter of the pipe 5 to be horizontally calibrated, and when the pipe 5 is bitten, the upper jaw part 2C
The tip edges of the lower jaw part 2B and the lower jaw part 2B shall face each other with a slight distance apart, and the width of the part that bites the pipe 5 shall be 3 times the outer diameter of the pipe 5.
, about 5 times as large.

The jaw fittings 2 grip the ends of the left and right adjacent pipes 5, 5,
By inserting the bolts 7 into the bolt insertion holes 6, 6 that run vertically through the upper and lower jaw parts 2C, 2B and the bolt insertion holes previously drilled in both the pipes 5, 5, and tightening them with the nuts 8, the pipes 5, 5 is fixed.

In addition, for installation to the support column 4, before fixing the pipes 5, 5, bolt insertion holes 9 that penetrate from the two bases to the back plate 1,
A bolt 11 is inserted along a bolt insertion hole 10 formed in a predetermined position of the support 4, and the support is fixed by tightening a nut 12.

Figure 5 shows the bicycle road prevention shelf after assembly.

It goes without saying that when the horizontal pipe 5, which is the pipe fixing metal fitting of this invention and the above-mentioned structure and serves as a guardrail, is fixed to the support 4, the head end and leg end of the bolt etc. do not protrude toward the aisle, making it safe. By providing the gusset retainer 3, the jaw fitting 2, which extends widely and supports the pipes 5, 5, can withstand a large load from above, so it will not bend due to snow accumulation or many people leaning on it. Alternatively, the risk of destruction can be eliminated.

As explained above, the pipe fixing fitting of this invention not only can reliably support horizontal pipes, but also can be installed between the front lower part of the back plate and the lower jaw of the jaw fitting to withstand loads from above. The gusset retainer works effectively, and compared to the conventional structure in which a similar metal fitting is bolted directly to the support, the metal fitting is significantly stronger, and it has many advantages, such as being easier to manufacture and assemble.
