However, the swimsuit for women has large openings in the neckline, back, waist, and sides, so that water and air inevitably enter through the openings during swimming. Resulting in. This invasion of water or air not only increases the substantial amount of the swimmer and increases the propulsive drag force, but also vibrates the edges of the openings to form turbulence and increases propulsive resistance with water. Will result. And, in the case of breaststroke which makes complicated exercises in water, the relationship with water in each part of the swimsuit is different, and a dedicated swimsuit for swimming has been demanded.

The present invention has been made in view of the above problems, and in consideration of the relationship of each part with water, in particular, the resistance to water at the time of breaststroke is reduced, and the rectification and drainage are excellent. It is an object of the present invention to provide a female swimsuit suitable for swimming.

[0005]

A female swimsuit according to the present invention is a swimsuit for women sewn with various stretchable fiber cloth materials or sheet cloth materials, and swims in a portion facing a water flow during swimming. A fine ridge formed integrally with the surface of the cloth by a stretchable resin material such as vinyl chloride, synthetic rubber, polyurethane, and silicon, which is installed in the direction parallel to the current flow of water, so as to adhere to the fibers of the cloth. The main features are a tightening rectification structure composed of rows and a drainage structure that is sewn with elastic net cloth and is located near the opening where water enters during swimming. For competition, the tightening rectification structure can be configured in the chest and hips of the swimsuit body, and the drainage structure can be configured in the center of the back. That.

The swimsuit body is divided into a front cloth that is continuous from the chest to the abdomen and the rear bottom, and left and right from the center of the back.
Two back cloths extending from the inferior position of the clavicle to the rear bottom position, and left and right front switching cloths that are sewn between the front cloth and the side cloth and form the front part of the shoulder strap at the upper end, respectively. It can be sewn between the back cloth and the side cloth, and can be sewn from the rear switching cloth that forms shoulder straps at the upper end. Both leg holes have their upper rims above the top of the hip bone. In addition to the high leg cut configured as described above, a structure with a front end in which the position of the upper edge is located slightly toward the front can be used to provide a structure especially for breaststroke competition.

[0007]

With the above-described structure, the female swimsuit has a chest tightening rectification structure that extends from the chest of the front cloth to which positive water pressure is applied during swimming to the groove drop portion, and the waist bulge rectification at the hip bulge. Since the structure is configured, the flow direction is regulated so that water flows in the vertical direction on the body surface, and it acts to eliminate the backward vortex, so that the resistance to the water flow can be reduced.

Further, since the water draining structure is sewn with the stretchable net cloth which is sufficiently distributed in the negative pressure portion during swimming, the invading water is immediately discharged from the water draining structure during swimming. The useless transport of water in is eliminated, the substantial amount of swimmers can be reduced, and the propulsive force can be increased.

Further, according to the structure of the present invention, both leg holes are arranged above the apex of the hip bone, and the high leg structure with a front is provided with the position of the upper flank slightly forward. It does not interfere with leg movements, especially in breaststroke.
