【Example】

 Embodiments of a tarp according to the present invention will be described below with reference to the drawings. The same reference numerals as those in FIG. 8 of the conventional example indicate the same members, and the description thereof will be omitted. FIG. 1 shows the first embodiment, and in order to eliminate the central support column 3, when the waterproof sheet 1 is supported by six support columns 2 and 2'as in the conventional example of FIG. A tension member 6 or 7 is bridged between the central columns 2'and 2'of the peripheral edge in a tensioned state.

Further, when the waterproof sheet 1 is supported by the four columns 2, the tension members 6 or 7 are bridged between the two columns 2 on the diagonal line in a tensioned state. In short, the tension members 6 and 7 are to be bridged in a tension state between the columns that connect the two of the columns and pass through the center of the waterproof sheet 1.

Next, a specific example of the tension member 6 will be described with reference to the embodiment shown in FIG. This tension member 6 is a belt-shaped tension member made of high tension synthetic resin or cloth, and is divided into three. One of the male and female buckles 6c is connected to both ends of the center tension member 6a, and the other buckle 6d is formed at one end of the tension member 6b to engage with the buckle 6c. ing.

A grommet 6e is formed at the center of the tension member 6a at the center and at one end of the tension members 6b at both ends. The tension member 6b has a structure such that its length can be adjusted. In the tension component 6 thus configured, the tip of the central column 2'is inserted into the grommet 1a formed on the peripheral edge of the waterproof sheet 1 via the grommets 6e of the tension components 6b at both ends. To do.

Then, the buckles 6d of the tension members 6b at both ends are engaged with the buckles 6c at both ends of the tension member 6a at the center, and the lengths of the tension members 6b at both ends are adjusted. The member 6 is bridged under tension between the central columns 2 '.

Numeral 8 is a short column having a length of about 50 cm, one end of which is inserted into and fixed to the grommet 6e of the central tension member 6a and the other end of which is inserted into and fixed to the grommet 1b formed in the center of the waterproof sheet 1. By interposing the short column between the tension member 6 and the waterproof sheet 1, the central portion of the waterproof sheet 1 is pushed upward to form a mountain shape.

Here, since the short column 8 is easily separated from the grommet 6e in the tension member 6a at the center, the short column 8 and the tension member are stretched by the belt 9 having the grommets 9a formed at both ends and having an adjustable length. We are trying to strengthen the fixation with 6.

That is, the grommet 9a formed at one end of the belt 9 is inserted into the upper end of the short strut 8, and the grommet 9a at the other end is overlapped with the lower surface of the grommet 6e in the central tension member 6a so that the lower end of the short strut 8 is overlapped. After the insertion, the length of the belt 9 is shortened and tensioned so that the short column 8 and the tension member 6 are not separated.

Next, a specific example of another tension member 7 will be described with reference to the embodiment shown in FIG. The tension member 7 is made of aluminum, stainless steel, or synthetic resin, and has a central hollow tension member 7a and tension members at both ends slidably inserted into the central tension member 7a. 7b and.

Further, a large number of screw insertion holes 7c are formed in the central portion and both end portions of the central tension member 7a, and the central tension member 7a is fitted and inserted in the tension members 7b at both ends. A large number of screw insertion holes 7d are formed in the corresponding portion, and an attachment hole 7e into which the tip of the central column 2'is fitted and inserted is formed at the opposite end. A male screw portion 8a is formed at one end of the short column 8 in this embodiment.

In the tension member 7 configured as described above, the two pillars 2 ′ at the center are fitted into the mounting holes 7 e of the tension members 7 b at both ends, and the pillars 2 ′ are attached to the waterproof sheet 1. It fits into the grommet 1a. Then, the tension members 7b at both ends are slid with respect to the tension member 7a at the center, and the length is adjusted so that the tension member 7 does not loosen.

In this state, the bolt 10 is inserted from the screw insertion hole 7c side of the central tension member 7a through the screw insertion holes 7d of the tension components 7b at both ends, and the screw components of the tension components 7b at both ends are inserted. By screwing the nut 11 into the bolt 10 protruding from the hole 7d to the lower surface, the central tension member 7a and the tension members 7b at both ends are integrated and bridged in a tension state.

Next, the male screw portion 8a at the lower end of the short column 8 is inserted into the central screw insertion hole 7c in the central tension member 7a, and the back surface thereof is screwed and fixed with the nut 11. Then, by inserting the tips of the short columns 8 into the grommet 1b of the waterproof sheet 1, the central portion of the waterproof sheet 1 is pushed upward to form a mountain shape.

In this way, after the tension members 6 or 7 are fixed between the central columns 2 ′ in a bridging tension state, the short columns 8 are attached to the center of the waterproof sheet 1 at the centers of the tension members 6 and 7. Since the waterproof sheet 1 has a mountain shape by interposing between them, rainwater and the like flow from the top toward the peripheral edge, so that the rainwater and the like do not collect on the waterproof sheet 1.

In the above-described embodiment, the waterproof sheet 1 is stretched in a mountain shape by the tension members 6 and 7 and the short columns 8, but in the examples of FIGS. 4 to 7, the waterproof sheet 1 is attached to the columns 2 '. The waterproof bar 1 is stretched in a chevron shape by using the elastic rods 12 between them. In the figure, reference numeral 12 is a synthetic resin having a length longer than the distance between the two columns 2'on the line where the line connecting the two columns passes through the center of the waterproof sheet 1. , An elastic rod made of metal or wood. The elastic rod 12 is formed at both ends with insertion holes 12a into which the upper ends of the columns 2'are inserted.

In addition, on the back surface of the waterproof sheet 1, a cloth-like material is sewn on a line passing through the center of the waterproof sheet 1 so that the elastic rod 12 can be inserted. To form the support portion 1c. Then, the elastic rods 12 are inserted into the supporting portions 1c of the waterproof sheet 1, and the insertion holes 12a at both ends are fitted to the upper ends of the central columns 2 '.

At this time, since the length of the elastic rod member 12 is longer than the length between the support columns 2 ′, the elastic rod member 12 bends. The chair 1 has a bulged upper part. Therefore, rainwater or the like flows from the top toward the periphery, so that rainwater or the like does not collect on the waterproof sheet 1.

FIG. 7 shows another embodiment of the connecting means for connecting the elastic rod 12 and the column 2 ′. In the above example, the insertion hole 12 a of the wire breaking rod 12 is inserted into the upper end of the column 2 ′. In this embodiment, a stopper 13 is fixed to the upper end of the column 2 ′, and a bolt / nut 14 is used in the stopper 13 to insert the elastic rod member 12. 12a is fixed, and various means other than the above can be considered as means for fixing the elastic rod 12 and the support 2 '.
