DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tent fabric for a telescopic simple tent structure and a method of mounting the same. The telescopic simple tent structure is used in a place where a telescopic covering is temporarily required, for example, a construction site or an event site. The present invention is particularly disclosed in Japanese Patent Application No. 4-195793 (Heisei 4).
Tent fabric developed for a simple tent structure (filed on June 11, 2012, not published at the time of filing of the present application) and a method of attaching the tent fabric, but of course can be applied to other types of tents.

[0002]

2. Description of the Related Art Japanese Patent Application No. 4-195793 discloses an invention of a simple tent having the following elements, as shown in FIGS. That is, the invention of the first application of the above-mentioned prior application relates to (a) pillars 1, which are erected at four corners so as to form a square, and (b) are arranged in parallel with each other, and both ends can be moved up and down to the pillars. The combined beam member 2, (c) the ridge member 3 laid horizontally between the beam members, (d) the tent ground 4 stretched on the ridge member and fixed to the beam member, and (e) the beam member is raised and lowered. Driving means 5. The invention of the second aspect is characterized in that the beam member 2 and the ridge member 3 are extendable and contractible. The third aspect of the invention is characterized in that the two tent grounds 4 fixed to the beam members are partially overlapped and stretched.

In this conventional invention, since both the beam member 2 and the ridge member 3 are extendable, the stretched area of the tent ground may vary. Therefore, the two tents fixed to the beam member 2 are partially overlapped and stretched correspondingly. It is important that rainwater does not collect in this tent. As a countermeasure against rainwater, an inclined groove (see a broken line in FIG. 6) for discharging rainwater is formed in an intermediate portion of the tent. This inclined groove is V-shaped when viewed from one side, and linear when viewed from the other side,
The head is inclined.

[0005]

However, a rectangular tent is used in the conventional tent. When the tent is actually assembled, the V-shaped inclined groove formed as a countermeasure against rainwater is used. It turned out that it was not suitable for practical use because the tent fabric was forcibly pulled or, conversely, a slack portion was formed. To solve this, we first attempted draping using a computer. Draft cutting refers to the elongation of the material used for the tent, the direction of tension, the tensile strength, etc. Is a way to In this way, FIG.
(One of the two tent grounds fixed to the beam member 2,
As shown in the figure, a plurality of narrow fabrics were sewn in the direction in which rainwater flows so as to be symmetrical with respect to the center line. This approach worked well when the tent support telescoping frame was at its maximum dimensions, but when the tent support telescoping frame was reduced, the centerline moved as shown in FIG. In this way, draping is a method of cutting and sewing cloth so that wrinkles and sagging cannot occur in a fixed shape, and is not suitable as a method of manufacturing a tent base in a telescopic tent structure. It is. It can be said that it is extremely difficult to attach a tent to a telescopic beam or ridge member without slack.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a trapezoidal tent having a trapezoidal shape and to attach the trapezoidal tent to a telescopic beam or ridge member so as not to be slackened. I do.

Is fixed to the target member using the eyelet-reinforced hole.

[0009]

According to the present invention, one side of the trapezoidal hypotenuse is fixed, and on the other side of the trapezoidal hypotenuse, any one of the belt-like portions is used as the target member in accordance with the length of the target member to be set and to be set with the surplus fabric. Fix it. Since a plurality of strips are set at predetermined intervals, the length can be adjusted by selecting one of them.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying embodiments. FIG. 1 is a front view of a simple tent according to the prior art, which is a starting point of the present invention as described above, FIG. 2 is a schematic plan view thereof, and FIG. 6 is a schematic side view thereof. After the fabric 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 includes a fixed beam 2a.
The ridge member 3 also includes a fixed ridge 3a and a movable ridge 3b. Both ends of the movable beam 2b are movable into the fixed beam 2a. Both ends of the movable building 3b can also move into the fixed building 3a. Therefore, the stretched area of the tent ground may vary.

In the present invention, as in the prior art, two tents 4 and 4 are usually partially overlapped and stretched. The two tents are trapezoidal. In FIG. 2, each of them looks rectangular. However, as shown in FIG. 6, the long side of the trapezoid has a V-shaped inclined groove formed as a countermeasure against rainwater. Yes, it is trapezoidal when viewed from a plane. FIG. 3 is a plan view of the tent on one side, and FIG. 4 is a back view of the tent on one side. The two tents are attached by partially overlapping the short sides 4a of the trapezoid with each other. As an example of the size of the trapezoid, the maximum dimension is about 13.2 m on the long side 4b and about 6.5 m in height.

As shown in FIGS. 3 and 4, a large number of holes 6 reinforced with eyelets along the trapezoidal contour are set at intervals of about 25 to 30 cm. The one oblique side 4c of the trapezoid is folded back over a width of about 10 cm to form a bag-shaped portion 4e. It is preferable to insert a reinforcing pipe 7 into this portion and use it as a winding core (details will be described later).

As shown in FIG. 4, strips 8 having a width of about 10 cm are formed at intervals of about 50 cm. As shown in FIG. 5, the band-shaped portion is obtained by folding a tent cloth into a fin shape and sewing the tent cloth with a sewing machine. Along this band 8 , a number of holes 6 reinforced with eyelets are set at intervals of about 25 to 30 cm. The eyelet-reinforced hole 6 in the band 8 is not exposed on the tent surface. The number of the band-shaped portions 8 is usually sufficient in about 5 to 10, but may be larger or smaller.

The method of using the tent of the present invention is as follows. In the following description, “beam” and “building” are used for convenience, and may be reversed.

As described above, the two tent bases 4 and 4 are attached by partially overlapping the short sides 4a of the trapezoid with each other.
Attachment between the tent ground 4 and the beam member 2 or the ridge member 3 is performed by connecting the rope (not shown) hanging on the eyelet-reinforced hole 6 of the tent ground 4 and the beam member 2 or the ridge member 3.
Regarding the trapezoidal oblique side, the side 4d where the bag-shaped portion is not formed is first fixed to one side of the beam member 2, and a tent ground is set along the ridge member 3.

At this time, as shown in FIG. 6, the short side of the trapezoid is kept as it is, and the tent cloth at the center of the long side of the trapezoid is lowered by 1.2 m to 1.5 m so that the rainwater discharge V A character-shaped inclined portion 4f is formed. In order to maintain the shape of the lowered inclined portion, a flexible pipe 10 is provided in parallel with the beam member 2 like "Yajirobe", and both ends of the pipe are grounded with a rope 9 or the like. To pull.

In order to adjust the length of the beam member 2 in the beam direction by expanding and contracting the beam member 2, the tent area 4 and the beam member 2 are disengaged from each other at the overlapped portion to increase or decrease the tent area, and then rejoined. Adjust. This is no different from the prior art.

A feature of the present invention is the length adjustment in the ridge direction.
When the ridge member 3 is expanded and contracted to adjust the length in the ridge direction, for example, when the ridge member 3 is reduced, the cloth 4d on the side where the bag-shaped portion 4e is not formed is fixed to one side of the ridge member 3.
Excess dough is generated in the dough 4c on the side where the bag-shaped portion 4e is formed. At this time, the excess dough is wound using the bag-shaped portion 4e into which the reinforcing pipe 7 has been inserted as a winding core. Then, when the tent extension area reaches the position of the ridge member in the reduced state, the band portion closest to the plurality of band portions 8 is joined to the other beam member 2. The connection may be fixed by a rope using the eyelet reinforcing hole 6 provided in the belt-shaped portion 8 . The wound excess fabric may be fixed to the other beam member 2 by tying it with a rope or the like.
When expanding the fabric in the ridge direction, follow the reverse procedure.

In the above embodiment, the reinforcing pipe is inserted only on the winding side, but the reinforcing pipe may be provided on the fixed side as well.

[0021]

According to the present invention, it is possible to easily attach a trapezoidal tent to a beam or a ridge member which expands and contracts, without loosening. Moreover, since it is only necessary to provide a plurality of fin-shaped, band-shaped portions having holes reinforced with eyelets along the trapezoidal hypotenuse of the tent ground, the structure is very simple, and mass production is possible in a factory. .
