DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an awning which is excellent in waterproofness and has excellent waterproof durability.

[0002]

2. Description of the Related Art For example, a large awning used for camping or the like is composed of a roof having an outer curtain formed in a pyramid shape, and side surfaces surrounding the skirt of the roof at four rounds. Have been. Among them, the roof is required to have excellent waterproofness against rainwater. As conventional waterproofing measures,
The sides of four curtains cut into a triangle are overlapped and sewn, and a sealing agent mainly composed of synthetic rubber is applied to the sewn portions to perform waterproofing.

[0003] However, the above waterproofing measures not only increase the cost because of two or more processing steps, but also have the drawback that the sealant deteriorates over a long period of use and the waterproofness decreases. In particular, since the center of the pyramid is supported by the pillars and the roof is the area where the load is concentrated most, a reinforcing cloth or the like is superposed on the roof, and the sewn portions overlap in a complicated manner. This makes it easy to form a gap that is disadvantageous to waterproofness in the overlapped portion, which has been a cause of reducing waterproof durability.

As a countermeasure against the above-mentioned problem, a method of fusing the overlap portion of the curtain cloth or the webbing by welding is considered instead of the suturing 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 is not necessarily greater than the bonding force by the suturing means, the waterproofing to be equal to or greater than the suturing means There was a problem that durability could not always be obtained.

[0005]

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

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a plurality of curtains cut into a triangular shape by superposing and connecting mutually pieces into a polygonal pyramid, and the inside of the top area of the polygonal pyramid. The roof is formed by reinforcing the roof with a cloth, and the center of the top of the roof is supported from the inside or lifted from the outside. The entire cloth reinforcement region is formed into a three-layer structure by straddling the lined curtain cloth and forming along the inner edges of the overlapped portions on both outer sides of the left and right curtain cloths, and at least the curtain cloth in the reinforcement region. And a region including the overlapping portion and an adjacent portion thereof are integrally fused.

[0007] In this manner, a plurality of webbings are straddled on the left and right curtain fabrics, and are formed along the inner edges of the overlapping portions on both outer sides of the left and right curtain fabrics, so that the entire reinforcing area by the webbings is 3 inches. Because of the layer structure, the three layers can be easily fused without forming a non-fused gap by the fusion means. In addition, in the three-layer reinforcement region, at least the region including the overlapping portion of the curtain cloth and the adjacent portion thereof is integrally fused, so that waterproof durability equal to or more than the bonding force of the suturing means can be secured. .
