Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tent member which also serves as a tent support and an awning. It also relates to a tent using the tent member.

[0002]

2. Description of the Related Art As a pillar for a tent for outdoor use, temporary use, warehouse use, etc., a tube woven with a tough thread and having a film for gas barrier formed thereon is used, and gas is applied to the tube at the time of use. It is known that it is press-fitted into a pillar. In this case, it is necessary that the above-mentioned tube be curved in an arch shape by press-fitting gas. When setting up a tent, for example, three columns are used so that they cross each other at the upper part, and awnings are stretched in advance between the columns by sewing, or tents sewn in a dome shape from above the columns are sewn in advance. To cover.

In order to make the tube bend into an arch shape by press-fitting gas, special weaving measures are made as described below. That is, when weaving the tube, the shrinkage rate of the yarn that forms one half-face of the tube in the cylinder axis direction of the tissue is low, and the shrinkage rate of the yarn that forms the other half-face of the tube in the cylinder axis direction of the tissue. Is set to a high shrinkage ratio. If the tube is heat-treated and then contracted after weaving, the lengths of the upper half surface and the lower half surface of the tube will be different. Therefore, if gas is pressed into the tube after the heat treatment, the tube is curved in an arch shape.

[0004]

The tent having the above-described structure can be assembled into the tent in a very short time only by pressurizing gas into the tube, and can be made extremely compact only by removing the gas from the tube. .

As described above, this tent is constructed such that, for example, three columns are used so that they cross each other at the upper part, and an awning is stretched by sewing between the columns in advance, or the tent is preliminarily attached from above the columns. It is necessary to cover the awning sewn into a dome shape.

However, the method of preliminarily tensioning the awnings between the struts by sewing complicates the sewing process considerably, and the airtightness of the struts may be impaired when the awnings are connected to the struts.

The method of covering the awning sewn in a dome shape in advance from the top of the column also has a complicated sewing process, and has a problem that the awning needs to be fixed after the awning is coated from the column.

[0008] Under such a background, the present invention provides a tent member for producing a tent member and an awning integrated in a weaving process, and a tent using the tent member. It is intended.

[0009]

The member for a tent according to the present invention has one or two or more tubular texture portions (1A) formed in one of the warp and weft directions during weaving and the tubular texture thereof. Department
Areas other than (1A) are formed in the non-cylindrical tissue part (1B), and
Threads in the tubular axis direction of one tissue (x) of the front and back tissues (x) and (y) constituting the tubular tissue portion (1A) and the other tissue
The yarn extending in the cylinder axis direction of (y) is configured so that the elongation behavior when gas is injected into the cylindrical tissue portion (1A) is relatively different, or the contraction rate during heat treatment is relatively different. It is characterized in that they are configured differently.

The tent of the present invention is formed when the above-mentioned tent member (1) or a heat-treated tent member (1) and the tubular tissue portion (1A) of the tent member (1) are filled with gas. A sheet member (2) that covers both open ends of the three-dimensional shape of a kamaboko,
And a bottom member (3) for covering the bottom of the semi-cylindrical shape.

The present invention will be described in detail below.

In the tent member of the present invention, one or more tubular tissue portions (1A) are formed in one of the warp and weft directions at the time of weaving, and the tubular tissue portion (1A) is formed. Areas other than the above are formed in the non-cylindrical tissue portion (1B).

When forming the tubular tissue portion (1A) in the width direction during weaving, for example, a weave that initially yields a flat woven fabric is used to form the non-cylindrical tissue portion (1B). Then, the warp is divided into two groups, front and back, and weft insertion is performed on the upper warp group to obtain a front cloth, and weft insertion is performed on the lower warp group to obtain a back cloth. As a result, a tubular tissue portion (1A) having a predetermined diameter is formed, and the non-cylindrical tissue portion (1B) is formed by shifting to a weave in which a flat woven fabric is obtained again. By adopting such a weaving method, weaving direction (1B)
→ (1A), (1A) → (1B), (1B) → (1A) → (1B), (1A) → (1B) →
A woven fabric having a structure such as (1A), (1B) → (1A) → (1B) → (1A) → (1B) is obtained.

When the tubular structure portion (1A) is formed in the weaving direction at the time of weaving, a weaving method in which a hollow weave portion and a non-woven weave portion are formed in the width direction of the woven fabric is adopted. Cylindrical tissue part (1B)
And the tubular tissue portion (1A) are simultaneously formed. As a result, (1A) − (1B), (1B) − (1A) − (1B), (1
A woven fabric having a structure such as B)-(1A)-(1B)-(1A)-(1B) is obtained.

Since the weaving width at the time of weaving is limited in any of the above methods (although if a special weaving method is adopted, it is possible to obtain a wide woven cloth many times larger than the width of the loom), When making a tent of a certain size or more, the tent member (1) obtained as described above is joined by sewing or the like to form a large tent member. Even when splicing, it is only necessary to perform linear sewing,
The sewing work is extremely easy.

Since the tubular tissue portion (1A) is a portion to be used as a tent column by pressurizing gas into the tubular tissue portion (1A) later, it is required to have airtightness. Therefore, at least the outer layer is a single layer or a multi-layered airtight film which is a heat-fusible layer (1C) is inserted into the inner surface of the tubular tissue part (1A), and the gas is press-fitted and heat-treated for its airtightness. It is desirable to take measures such as integrally laminating the film (1C) on the inner surface of the tubular tissue portion (1A). When the airtightness is imparted to the inner surface side of the tubular structure portion (1A) as described above, reliable airtightness without coating defects such as uneven thickness and pinholes of the airtightness imparting layer can be obtained. Further, a single or multi-layer airtight film including a heat-fusible layer on at least the inner layer on the outer surface of the tubular structure portion (1A).
It is desirable to take measures such as integrally laminating (1C).

When a high degree of airtightness is required, as the airtight film (1C), a gas barrier resin layer such as ethylene-vinyl alcohol copolymer, acrylonitrile copolymer, polyamide, or polyvinylidene chloride is used. It is preferable to use a multi-layer film containing at least one layer.

Since the non-cylindrical tissue part (1B) is a part that serves as an awning, at least one surface of the non-cylindrical tissue part (1B) has a surface for the purpose of waterproofing, water repellency, antifouling, and weather resistance. It is desirable to form a coating / impregnation layer (1D). Such a coating
The impregnated layer (1D) can also be formed on at least one surface of the tubular tissue portion (1A). The coating / impregnation layer (1D) is formed by a method such as coating with a resin liquid, spray coating with a water repellent, and thermocompression bonding of a resin film.

In the present invention, the tubular tissue portion (1A)
Of the tissues (x) and (y) constituting the front and back, the yarn in the axial direction of one tissue (x) and the yarn in the axial direction of the other tissue (y) are i) the tubular shape The elongation behavior at the time of gas injection into the tissue part (1A) is relatively different, or ii) the shrinkage rate at the time of heat treatment is relatively different.

In the case of i), one of the front and back tissues (x) and (y) forming the tubular tissue portion (1A) is relatively gas-like in the direction of the cylinder axis of the tissue (x). A thread with a small expansion rate when press-fitting,
The yarn extending in the cylinder axis direction of the other structure (y) is formed by a yarn having a relatively large expansion rate when gas is injected.

In the case of ii), one of the front and back tissues (x) and (y) constituting the tubular tissue portion (1A), which is one of the tissues (x) extending in the cylinder axis direction, is relatively heated. The yarn having a large shrinkage is formed, and the yarn extending in the cylinder axis direction of the other tissue (y) is formed by a yarn having a relatively small heat shrinkage.

In either case of i) or ii), a tent member including a tubular tissue portion (1A) and a non-cylindrical tissue portion (1B)
In (1), depending on the size of the target tent, one piece or a plurality of pieces are spliced together to have a predetermined size.

In the case of the above ii), by heating the tent member (1), yarns directed in the axial direction of the tissues (x) and (y) on the front and back of the tubular tissue portion (1A) The cylindrical tissue portion (1A) can be curved in an arch shape due to the difference in contraction rate. This heat treatment for bending may be performed either before or after the sewing process for seaming.

At least a part of the yarn used for weaving the tent member (1) including the tubular tissue portion (1A) and the non-cylindrical tissue portion (1B) is a high-strength fiber or an ultra-strength fiber. It is desirable that the yarn is made.

A valve (4) for introducing / extracting gas is provided at an appropriate portion of each tubular tissue portion (1A). The type of gas introduced from this valve (4) is not limited, but air is usually used. The gas pressure is often several to ten and several atmospheres.

The tent covers both the above-mentioned tent member (1) and both open ends of a semi-cylindrical body formed when gas is enclosed in the tubular tissue portion (1A) of the tent member (1). A sheet member (2) and a bottom member that covers the bottom of the semi-cylindrical shape
(3) Composed of and.

The sheet member (2) is composed of a semi-circular waterproof cloth, a cloth obtained by dividing the cloth, a mesh cloth, etc., and a line fastener (zipper) or a hook-and-loop fastener is provided on the side where people come in and out as necessary. Attach.

The bottom member (3) is composed of a bottom member (3A) for a bottom surface such as a waterproof cloth and a foam sheet, and a bottom member (3B) for an outer frame such as a foam and a pipe. Bottom member for outer frame

The tent thus obtained is useful as a tent for purposes such as outdoor use, temporary use, and factory use.

[0030]

In the tent member (1) of the present invention, the tubular tissue portion (1A) which becomes the support and the non-cylindrical tissue portion (1B) which becomes the awning are integrated by weaving. Therefore, as compared with the conventional method in which the strut portion and the awning portion are separately manufactured and then assembled by sewing or the like, all or most of the sewing process can be omitted, so that productivity is significantly increased and airtightness and The sewing inspection process is also extremely simple.

The process of assembling the tent is also extremely simple, and the tent installation work is shortened to, for example, several tens of seconds. Storage after using the tent is extremely easy.
