Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a structure for attaching sheets for garages, automobile canopies, or awnings such as vinyl houses and tents.

[Prior Art] Conventional sheets have eyelet-like holes arranged around the periphery and are tied together with strings that are threaded through the holes.

In addition, eggplant rings are attached in a staggered manner to the back of the sheet that is placed on the rod-shaped frame bones, and both sides of the rod-shaped frame bones are alternately sandwiched between the eggplant rings, and the strings connected to the rings are pulled and tightened in sequence, so that the sheet is attached to the rod-shaped frame bones. It is also known that the
(See Publication No. 14551).

[Problems to be Solved by the Invention] In the above-mentioned former prior art, the tension was not stable in the middle part of the sheet, and when fastening parts were provided at various places, it required a lot of work to fasten each part.

In addition, the latter conventional technique described above requires a large number of metal eggplant rings, which is expensive, and when strong winds blow, the metal rod-shaped frame and the eggplant rings may slip, causing track noise. It was inevitable.

The present invention aims to provide a sheet tensioning structure that tensions the sheet evenly throughout, requires relatively few steps, and does not generate metal track noise.

[Means for solving problems] This will be explained with reference to the drawings.

In the awning sheet tension structure according to this invention, tourniquets 3 are attached at predetermined intervals on a sheet 2 that covers the outer surface of rod-shaped frame ribs 1 arranged in parallel, tracing a line X-X along the rod-shaped frame ribs 1. The tourniquet 3 is sewn 4 to the sheet 2 at the center of its length so as to obliquely intersect the line X-X.
Strap insertion holes 5 and 6 parallel to is tension-bound to a fixed body 8 placed apart from the rod-shaped frame 1.

[Example] As shown in FIGS. 1 to 6, in the sheet 2 that covers the outer surface of the rods 1 arranged in parallel, the rod-shaped frame ribs 1
Tourniquets 3 are arranged at predetermined intervals along the line Further, at both ends of the tourniquet 3, string insertion holes 5 and 6 are provided parallel to the line XX.

As shown in FIG. 7, the tourniquet 3 is straddled over the rod-shaped frame 1, the string insertion holes 5 and 6 are arranged in series, and the string 7 is inserted into the string insertion holes 5 and 6 as shown in FIGS. 8 and 9. death,
As shown in FIG. 10, the tensioning structure of the awning sheet is constructed by tensioning both ends of the string 7 to a fixed body 8 placed apart from the rod-shaped frame 1.

The reason why the tourniquet 3 is tilted in the above structure is to give a twist so that the string insertion holes 5 and 6 do not overlap when the tourniquet 3 is straddled over the rod-shaped frame 1 and both ends are placed on the same side.

Further, the fixed body 8 that binds the string 7 may be a bent portion at both ends of the rod-shaped frame 1, or may be a ring fixedly provided to the rod-shaped frame 1.

When the sheet 2 is, for example, a canopy-shaped garage roof or an automobile canopy, the rod-shaped frame 1 has a gate-shaped shape.

[Operation] The present invention is constructed as described above, and the tension of the sheet 2 is also achieved by the tension of the string. In this case, the tension of the sheet 2 is uniform and excellent throughout to a degree that has not been seen in conventional roofing sheets. As a result of experiments, it has been confirmed that the entire surface of the sheet 2 is tensioned substantially uniformly.

When the string 7 is sufficiently tensioned to pull the tourniquet spanning the rod-shaped frame 1, there is no uneven pulling of parts of the sheet 2, and the tension of the sheet 2 is smooth.

[Effects of the invention] According to the invention, the tension of the awning sheet can be easily made smooth and strong, and the process is also advantageous in that it requires relatively little effort.

Moreover, it also has the advantage of not producing metal track noise even in strong winds.
