Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tent cloth in a telescopic simple tent structure and a method for mounting the tent cloth. The telescopic simple tent structure is used in a place where a telescopic covering is temporarily required, such as a construction site or an event venue. The present invention is a tent cloth and a method of mounting the same, which have been particularly developed for the simple tent structure of Japanese Patent Application No. 4-195793, but can of course be applied to other tents of the same type.

[0002]

2. Description of the Prior Art Japanese Patent Application No. 4-195793 discloses an invention of a simple tent having the following elements, as shown in FIGS. That is, in the invention of the above-mentioned prior application, (a) a pillar 1 which is upright at four corners so as to form a square, and (b) a beam member 2 which is arranged in parallel with each other and whose both ends are engaged with the pillar so as to be able to move up and down. , (C) a ridge member 3 laid horizontally between the beam members, (d) a tent cloth 4 stretched on the ridge member and fixed to the beam member, (e) a driving means 5 for moving the beam member up and down,
It is characterized by having. In this conventional invention,
Since both the beam member 2 and the ridge member 3 are expandable / contractible, the tensioned area of the tent cloth may vary. Therefore, correspondingly, the two tent fabrics fixed to the beam member 2 are partially overlapped and stretched.

It is important to prevent rainwater from collecting in the tent. As a measure against rainwater, an inclined groove for draining rainwater (see the broken line in Fig. 6) is formed in the middle of the tent. The inclined groove is V-shaped when viewed from one side, and is linear when viewed from the other side, and its head is inclined. A rectangular tent cloth is used in this conventional tent, and when actually assembled, the tent cloth was forcibly pulled or reversed due to the V-shaped inclined groove formed as a measure against rainwater. It was found that it was unsuitable for practical use, as it had excessive slack.

In order to solve this, the present applicants have filed Japanese Patent Application No. 5-141584 (Japanese Patent Laid-Open No. 6-330659).
The invention of This prior invention is a trapezoidal tent fabric in a telescopic simple tent structure in which at least one of a beam member and a ridge member is capable of expanding and contracting, and having a hole reinforced with eyelets along at least a portion along the trapezoidal contour. Is characterized by. Preferably, a plurality of pleated portions are provided along the hypotenuse of the trapezoid, having holes reinforced with eyelets. In this prior invention, one side of the trapezoidal hypotenuse is fixed, and on the other side of the trapezoidal hypotenuse, excess fabric is accommodated and any one of the pleated portions is formed as a contour member of the tent structure according to the size of the tent structure. Fixed to. Since a plurality of pleated portions are set at predetermined intervals, the length can be adjusted by selecting one of them.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
Although the invention No. 659 is very effective and actually useful, it has been found that there is room for improvement in the following points. I want to shorten the time to attach the tent fabric to the simple tent structure as much as possible. A large number of eyelets are required on the edge of the tent cloth, which is a factor that raises the cost. Use a special water resistant rope for fixing the tent cloth to the ridge members or beam members of the simple tent structure. This is relatively expensive and is a factor that raises costs. Over time, the rope stretched and the tent sheet slackened, so it was necessary to tighten it regularly. Also, when strong winds blow, the eyelets may be damaged.

The present invention is an improved invention of the invention of JP-A-6-330659, and an object thereof is to eliminate the above-mentioned drawbacks.

[0007]

The tent fabric of the present invention comprises:
A trapezoidal tent cloth stretched on a telescopic simple tent structure in which at least one of a beam member and a ridge member is expandable and contractible, and a bag-shaped portion is provided on each of the trapezoidal hypotenuses, along at least one of the trapezoidal hypotenuses. A plurality of pleated portions having a bag-shaped portion at the tip are provided, and a plurality of cutout holes are provided at positions adjacent to the bag-shaped portion.

The tent cloth mounting method of the present invention is a tent cloth mounting method in a telescopic simple tent structure in which at least one of a beam member and a ridge member is capable of expanding and contracting, and one of the trapezoidal hypotenuses is used as a reference. Then, on the other side of the trapezoidal side, in the method of accommodating excess fabric, and fixing any one of the pleated portions to the contour member of the tent structure according to the size of the tent structure, A plurality of notches provided at positions adjacent to the bag-shaped portion by passing the rod-shaped member through the bag-shaped portion provided and the bag-shaped portion at the tip of the fold-shaped portion that is closest to the contour of the tent structure. It is characterized in that it is fixed with a string-like member using a hole.

In this method, it is preferable that the cutout hole is provided so that the pipe is partially exposed at a position where the rope comes into contact when the rod-shaped member is passed through the bag-shaped portion and fixed by the string-shaped member.

Embodiments of the present invention will be described below with reference to the accompanying drawings. As described above, FIG. 1 is a front view of a simple tent according to the related art, which is a starting point of the present invention, FIG. 2 is a schematic plan view thereof, and FIG. 6 is a schematic side view thereof. After the cloth is attached, it looks like these drawings, and in that sense, it can be said to be an embodiment of the present invention.

As shown in FIG. 2, the beam member 2 is a fixed beam 2a.
And a movable beam 2b, and the ridge member 3 also includes a fixed ridge 3a and a movable ridge 3b. Both ends of the movable beam 2b can move into the fixed beam 2a. Both ends of the movable ridge 3b can also be moved into the fixed ridge 3a. Therefore, the stretched area of the tent cloth may change. In addition, the beam member and the ridge member may be a nesting type having three stages or more instead of two stages (not shown).

In the present invention as in the prior art, two tent cloths 4 and 4 are usually partially superposed and stretched. Both of these tent fabrics are trapezoidal. Each of them looks like a rectangle in FIG. 2, but as shown in FIG. 6, since there is a V-shaped inclined groove formed as a measure against rainwater on the long side of the trapezoid, the tent fabric is inclined accordingly. There is a trapezoid if you look at the tent cloth from directly above. FIG. 3 is a plan view of the tent cloth on one side, and FIG. 4 is a back view of the tent cloth on the one side. The two tent fabrics are trapezoidal short sides 4a
The sides are partially overlapped with each other and attached. As an example of the size of the trapezoid, the dimension at the maximum is a long side 4b of about 13 m,
Short sides 4c and 4d are about 6.5 m.

As shown in FIGS. 3 and 4, notched holes 6 are formed in the tent cloth along each of the oblique sides of the trapezoid (usually 2 to 5 places, in the illustrated example, 3 places). The cutout hole 6 has an elliptical shape with a short diameter of about 5 cm and a long diameter of about 15 cm, and the periphery is not reinforced with eyelets. The reason for not reinforcing with eyelets is that it is not necessary for cost reduction and in the usage described later, since no force is directly applied to the periphery of the cutout hole. If you can ignore this point, you can use eyelets. On each hypotenuse of the trapezoid, bag-shaped portions 4e, 4e are formed by folding back over a width of about 5 cm.

As shown in FIG. 4, on one side 4c of the hypotenuse,
Pleat-shaped portions 8 having a width of about 5 cm are formed at intervals of about 100 cm. As shown in FIG. 5, the pleated portion 8 is formed by folding a tent cloth in a pleated shape and sewing it with a sewing machine. The number of pleated portions 8 is usually about four, but may be larger or smaller depending on the size of the tent. About 5c at the tip of this pleated portion 8
A bag-shaped portion 8a having a width of m is formed. Notched holes 10 are formed in the tent cloth along the bag-shaped portion 8a at several locations (usually 2 to 5 locations, 3 locations in the illustrated example). The notch hole 10 has a diameter of 1 to 3 cm and the periphery thereof is not reinforced with eyelets. The reason for not reinforcing with eyelets is that it is not necessary for cost reduction and in the usage described later, since no force is directly applied to the periphery of the cutout hole. If you can ignore this point, you can use eyelets.

As will be described later, rod-shaped members (for example, pipes) are appropriately inserted into the bag-shaped portion 4e of the trapezoidal hypotenuse and the bag-shaped portion 8a at the tip of the fold-shaped portion. With the pipe inserted, the bag-shaped portions 4e and 8a are joined to the beam member of the simple tent structure, and the cutout holes 6 and 10 are formed.
It is fixed by tying it with a string-shaped member (for example, a rope or a band).

A method of fixing the tent cloth to the beam member of the tent structure will be described below. As described above, the two tent cloths 4 and 4 are attached by partially overlapping each other on the short side 4a side of the trapezoid. Since the two tent cloths 4 and 4 are fixed in the same manner, only one (for example, the lower half of FIG. 2) will be described.

First, the pipe 12 is inserted into the bag-shaped portion 4e of the hypotenuse 4d on the side without the fold-shaped portion 8. At this time, it is important that the pipe 12 is partially exposed and visible from the cutout hole 6 adjacent to the bag-shaped portion (see FIG. 7). Next, the bag-shaped portion containing the pipe is placed inside the beam member 2, and the notch hole 6
Is used to temporarily secure the band 14 (see FIG. 7). At this time, the band 14 contacts the pipe 12 in the cutout hole 6 and does not directly contact the cloth around the cutout hole 6.

Next, the tent cloth is pushed out from the temporarily fixed position toward the side where the pleated portion 8 is located, and the pleated portion 8 located closest to the terminal ridge member 2 is found. In the case of the maximum area, it may be the hypotenuse 4c on the side with the folds. When the pleated portion 8 is found, the pipe 12 is inserted into the bag-shaped portion 8a provided at the tip thereof. The band 14 is fixed to the ridge member 2 using the notch hole 10 provided adjacent to the pipe-shaped bag-shaped portion in the same manner as above. Here, not the temporary fixing but the final tightening.

Next, the V-shaped inclined portion for draining rainwater is set. As shown in FIG. 6, with the short side 4a side of the trapezoid left unchanged, the tent fabric at the center of the long side 4b side of the trapezoid is pulled down by 1.2 m to 1.5 m to incline the V-shaped slope for rainwater discharge. The portion 4f is formed. In order to maintain the shape of the lowered inclined portion, the flexible pipe 16 is provided in parallel with the beam member 2 like "Yajirobee", and both ends of this pipe are connected to the ground side with a rope or the like. Pull and fix the sheet and the pipe 16 with a shackle or the like.

Finally, the trapezoidal hypotenuse 4d that has been temporarily fixed and the ridge member are fully tightened.

"Temporary fastening" and "final fastening" in the above description
Is a difference in tightening degree of the band tightening tool 18. The temporary fastening is performed by tightening the band tightly with the band fastener 18. For this type of band fastener, for example, a load clamp or a turnbuckle known per se can be used.

[0022]

According to the present invention, the following effects can be obtained. The conventional method (JP-A-6-330659) required about 1 hour to stretch the two tent fabrics on the tent structure, whereas the present invention requires about 15 minutes. I saved time. In the present invention, since the pipes are passed through both ends of the tent cloth, it is easy to fold when disassembling. In the preferred embodiment, eyelets are not required, which reduces tent fabric processing costs. In the preferred embodiment, the area around the notch does not directly contact the band, so there is less chance of breakage.
