[Detailed explanation of the idea]

(Industrial Application Field) This invention relates to a fabric for attaching a tent seat. (Prior Art) Conventionally, as shown in FIG. 10, a sheet attachment member 1 for fixing a sheet constituting a tent to a tent support pipe has a connecting member attached to a portion close to both ear portions 2 of the sheet attachment member 1. There was a fabric product in which a large number of holes 3 for inserting ropes 6 were punched with a hole punch. The woven fabric used in this processed woven product is cut from a membrane material used for tent sheeting, which is made by coating a wide woven fabric with a synthetic resin. The center portion of this sheet attachment member 1 is joined along the longitudinal direction to the sheet 4 constituting the tent by welding or the like, and both ear portions 2 of this sheet attachment member 1 are connected to the tent supporting pipe 5 of the tent. from both sides, and connect the rope 6 to the corresponding hole 3 of both ears 2.
was inserted to fix the sheet 4 to the tent support pipe 5 of the tent. However, sheet 4 attached to the tent
may flap due to rain, wind, etc., and a large external force is applied to both ears 2 of the tent sheet attachment member 1, especially the holes 3, due to the flapping of the sheet, causing damage to those parts. Something happened. In addition, for serpentine tents and retractable tents,
The sheet 4 attached to the tent support pipe 5 of the tent is stretched when the tent is opened and closed, and stress is concentrated on both ears 2 and holes 3 of the sheet attachment member 1 joined to the sheet 4, resulting in damage. Something happened. In order to solve the above-mentioned problems, there has been a demand for the use of stronger membrane materials, but the reality is that membrane materials must be selected from a limited number of commonly available membrane materials. Therefore, as shown in FIG. 11, in order to reinforce both ears 2 of the seat attachment member 1, reinforcing ropes 7 are incorporated into the folded portions of both ears 2 of the seat attachment member 1, and then sewn. A seat attachment member 1 fixed by a bolt or the like is used, and at the same time, in order to reinforce the hole 3 of the seat attachment member 1, an eyelet is provided after drilling the hole with a punch. However, as described above, processing of the conventional seat mounting member 1 requires cutting the sheet membrane material, assembling the reinforcing ropes 7 to the both ears 2, drilling the holes 3, and processing the eyelets. However, most of these cannot be processed without manual labor and require a great deal of time and effort. (Problems to be solved by the invention) The present invention was created in view of the above problems, and includes cutting of the membrane material used for the tent sheet material and installation of reinforcing ropes for both ears. It is an object of the present invention to provide a fabric for attaching a tent sheet, which can eliminate the work of drilling holes and making eyelets. (Means for Solving the Problems) In order to achieve the above object, the present invention is a belt-like fabric made of heat-meltable synthetic fibers for fixing the sheet constituting the tent to the tent support pipe. The fabric includes a bag weave portion formed on both edges of the fabric, a core yarn woven in a plurality of aligned lines inside the bag weave portion, and a ground portion excluding the both edges. are woven as one piece during weaving,
A plurality of holes are formed by heat melting in two parallel rows on the left and right at appropriate intervals in the longitudinal direction of the fabric at locations close to the bag weave portions on both the left and right sides of the woven belt material. The gist of the paper was ``fabric for attaching tent seats.'' (Function) Therefore, in the fabric for attaching the tent seat of this invention, the formation of the central base portion to be joined to the seat and the formation of the hollow weave portions located at both ends of this belt-like fabric are required. and the weaving of the core material into this bag weave part are woven together during weaving, so it is necessary to incorporate reinforcing ropes into both selvedges for the purpose of reinforcing both selvedges of the fabric. It has become possible to omit this. (Example) Hereinafter, the fabric for attaching a tent seat according to the present invention will be described in detail with reference to the drawings. In the tent shown in FIG. 6, a plurality of tent supporting pipes 15 formed into a substantially portal shape are movably arranged side by side along a pair of rails, and a sheet forming the tent is arranged between the tent supporting pipes 15. This is a serpentine tent configured to be opened and closed in a serpentine manner by means of an X connecting rod 34 attached between the tent support pipes 15 based on the movement of the tent support pipes 15. Note that this sheet attachment fabric can be used not only for attaching sheets to serpentine tents, but also to any type of tent, such as an opening/closing tent or a suspension tent. The sheets 14 stretched over each tent support pipe 15 of this tent are made of resin-coated synthetic fiber woven fabric and have a predetermined flexibility. This sheet 14 is fixed to each tent support pipe 15 that maintains the shape of the tent by a tent sheet attachment fabric 11 (hereinafter referred to as fabric) that is fixed to the sheet 14 by sewing or high-frequency welding. -ing The fabric 11 of the present invention is made of heat-meltable synthetic fibers such as polypropylene and polyester. As shown in FIGS. 1 and 3, a hollow weave portion 12 is formed on both sides of the fabric 11, and a core yarn 17 is woven into the inside of this hollow weave portion 12. As shown in the longitudinal sectional view in FIG. 4 and the selvage structure diagram in FIG. At the same time as this tubular portion is formed, as shown in FIGS. 3 and 4, a large number of core threads 17 are aligned and woven straight into the tubular hollow portion. In addition, the size of this bag weave section 12 with core threads is designed depending on the required strength, but in the first embodiment described later, 48 polypropylene 680 denier threads were used per ear, and in the second embodiment, 24 polypropylene 680 denier threads were used per ear. It was used as a main thread. In these two examples, the base portion 18 had a thickness of 1 mm, and the width of the ear portion was different, but both had a thickness of 2.8 mm. The weave structure of the base portion 18 is a 3/1 warp double weave on both sides, as shown in the weave diagrams of the base portion in FIGS. 2 and 5, but is not limited to this.
Other weave structures such as 2/2 twill may also be used. In this way, the base portion 18 of the fabric, the bag weave portions 12 on both sides, and the core yarn 17 therein as a reinforcing material in place of the conventional reinforcing rope are woven together during weaving. It should be noted that weaving of the tent sheet attachment fabric 11 having such a hollow weave portion 12 can be easily carried out using a normal loom. A plurality of holes 13 are formed in two parallel rows on the left and right at appropriate intervals in the longitudinal direction of the fabric at locations close to the hollow weave portions 12 on both the left and right sides of the base portion 18 of the fabric 11. These holes 13 are formed all at once during weaving, and can be easily performed using an automatic machine such as a hot melt processing machine or a high frequency melt processing machine. Note that the hole 13 does not need to be completely opened as shown in FIG. 1, and may simply be a cross-shaped or straight-shaped slit. FIG. 5 shows the organization chart of the fabric for attaching the tent seat of this invention. In addition, as shown in FIG. 7, the hollow weave portions 1 at both ears of the fabric 11 for attaching the seat of the tent of this invention are shown in FIG.
2 may be provided, thereby further increasing the strength of both heel portions of the fabric 11. A specific example of the fabric for attaching the tent seat of this invention is shown below.

[Table] Next, the attachment of the sheet 14 constituting a tent using the fabric 11 constructed as described above to the tent support pipe 15 will be explained with reference to FIGS. 1 to 9. First, the fabric 11 is arranged on the surface of the sheet 14 in accordance with the spacing between the tent support pipes 15 that maintain the shape of the tent, and the central base portion 18 of the fabric 11 is attached to the sheet 14 along the longitudinal direction. It is joined by sewing or high frequency welding. Next, the fabric 11
The joined sheet 14 is attached to each tent support pipe 1.
Attach to 5. The sheet 14 is attached to the tent support pipe 15 by attaching the central ground portion 1 indicated by the striped threads 21 of the fabric 11 joined to the sheet 14.
8 to the tent support pipe 15, wrap the hollow weave portions 12 of both ears from both sides of the tent support pipe 15, and place the hollow weave portions 12 of both ears on the base portion 18 of the fabric 11 at locations close to the hollow weave portions 12 of both left and right ears. This is done by inserting the connecting members 16 into a plurality of holes 13 formed in parallel on the left and right at appropriate intervals in the longitudinal direction of the fabric 11. FIG. 9 shows a state in which the sheet 14 constituting the tent is fixed to the tent attachment pipe 15 using the tent sheet attachment fabric of this invention. The connecting member 16 is preferably a string, a wire covered with vinyl, or a synthetic resin connecting member, for example. In the above example, a case has been described in which on-site alignment, that is, joining of each sheet is performed at a work site, but this method is not necessarily required. In other words, if the situation at the sheet joining site is known in advance, a large number of The fabric with the holes formed therein can be joined to the sheet, and the thus formed sheet can be transported and installed as is. (Effects of the invention) As described in detail above, the present invention has a bag weave portion formed on both sides of the fabric, and a core yarn woven in a plurality of aligned lines inside the bag weave portion. Since the fabric is constructed so that the fabric and the fabric, excluding both ears, are woven together during weaving, the process of cutting the membrane material used for the tent sheet fabric and assembling reinforcing ropes to both ears is difficult. can be omitted. In addition, in the fabric of the present invention, the fabric is woven from heat-fusible synthetic fibers, and in the base portion of the fabric, in the vicinity of the bag weave portions on both the left and right ears, there is a A plurality of holes, in which the connecting members are inserted, are formed in two parallel rows on the left and right at appropriate intervals in the direction, and are continuously formed at one time during weaving by an automatic machine such as a hot melt processing machine. For this reason, it is possible to eliminate the work of drilling and grommeting a hole for inserting the connecting member, which was conventionally performed manually. Further, since the fabric has sufficient strength in the warp and width directions, the holes have sufficient strength so that reinforcement such as eyelet processing is not required. As a side effect, the durability of the connecting member used for the melted hole is improved compared to when it is inserted into a hole that has been processed with an eyelet, so a lower cost connecting member is used than before. can do.
