Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an awning having excellent waterproofness and durability.

[0002]

2. Description of the Related Art For example, a large awning used for camps or the like is composed of a roof portion in which an outer curtain is formed into a quadrangular pyramid, and side portions surrounded by the outer curtain around four skirts of the roof portion. Has been done. Of these, the roof part is required to have excellent waterproofness against rainwater. As a conventional waterproof measure,
The edges of four curtain cloths cut into a triangle were overlapped with each other and sewn together, and a waterproofing agent having a synthetic rubber as a main component was applied to the sewn portion for waterproofing.

However, the above-mentioned waterproofing measures have the drawbacks that not only the cost is high because the processing steps involve two or more steps, but also the sealing agent deteriorates and the waterproofness deteriorates after long-term use. In particular, since the center of the pyramidal portion of the roof portion is supported by the columns and the load is concentrated most, the reinforcing cloth and the like are laid on top of each other so that the sutured portions overlap in a complicated manner. This makes it easy to form a gap that is disadvantageous in waterproofness in the polymerized portion, which is a cause of lowering the waterproof durability.

As a measure against the above-mentioned problem, a method of welding the overlapped portion of the curtain cloth or the sack cloth by welding is considered in place of the stitching means. However, this method is advantageous in terms of cost because it reduces the number of processing steps, but since the bonding force by fusion bonding is not necessarily greater than the bonding force by the suturing means, it is comparable to or more waterproof than the suturing means. There was a problem that durability could not always be obtained.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an awning capable of improving waterproof durability of a roof portion while using a cost-effective fusing means.

[0006]

According to the present invention, which achieves the above-mentioned object, a plurality of curtain cloths cut into triangles are made into a polygonal pyramid by polymerizing and connecting pieces of each other to each other, and inside the top area of the polygonal pyramid. In the awning in which the roof part is formed by reinforced with a power cloth, and the top center of the roof portion is supported from the inside or is hung from the outside, the power cloth is composed of a plurality of sheets, and By straddling the curtain cloths arranged side by side, and forming along the inner edges of the overlapping portions on both outer sides of the left and right curtain cloths, the entire reinforcing region by these cloths has a three-layer structure, and at least the curtain cloths in the reinforcing regions are formed. It is characterized in that a region including the overlapped portion and its adjacent portion is integrally fused.

In this way, a plurality of sash cloths are laid across the curtain cloths arranged on the left and right, and are formed along the inner edges of the overlapping portions on both outer sides of the left and right curtain cloths so that the entire reinforced area by the sack cloth is three. Since it has a layered structure, reliable fusion processing can be easily performed without forming a non-fusion gap between the three layers by the fusion means. Moreover, in the three-layer reinforcing region, at least the region including the overlapped portion of the curtain cloth and its adjacent portion are integrally fused, so that it is possible to secure waterproof durability that is more than the binding force of the suturing means. .

Since no step is formed, the three layers can be easily and strongly fused without forming a non-fused portion by the welding process by the fusing means, and the reinforcing region 2Y is formed.
By integrally fusing at least the overlapping portion X of the curtain cloth 21 and the area Z including the adjacent portion N thereof, it is possible to obtain waterproof durability comparable to or higher than the bonding force of the suturing means, and cost. The waterproof durability of the roof portion can be improved while using the economically advantageous fusing means.

In the present invention, since the tension cloth 22 exerts a tensile force, it is preferable that both warp threads and weft threads of each of the tension cloths having high tensile strength be used, for example, aromatic polyamide fiber. And the like, which may be preferably woven and used as a strength cloth. As the curtain cloth 21 serving as the outer curtain, a conventionally known cloth cloth can be used, and for example, a canvas cloth made of a mixed yarn obtained by twisting hemp and polyester can be used.

Since tension is applied in the longitudinal direction of the force bands 23 and 24, it is preferable to use those having high tensile strength on the warp side. As the warp, aromatic polyamide fiber or the like can be preferably used as in the above. The weft thread is not particularly limited, and for example, polyester fiber or the like can be used. For fusion bonding of the cloth 21 and the cloth 22 or the like, a low melting point resin (copolymerized polyamide or vinyl chloride resin) tape is sandwiched between the cloths, and both outer sides of the tape are pressed with a heating bar, or the cloth 21 and the cloth cloth 22 are fused together. 22 and the like may be coated with a low melting point resin, and they may be overlapped with each other, and both outer sides may be pinched by a heating bar, or both may be used together. The width for overlapping the cloths is preferably 25 mm or more.
