BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for reducing the resistance of swimwear, and in particular, clothes for speed competition in which resistance to water during swimming during swimming competition and resistance to air during speed skating, bicycle competition, etc. are reduced. The present invention relates to a garment suitable for reducing fluid resistance.

[0002]

2. Description of the Related Art It has been known that a swimming competition in which a speed of 1/100 second is competing is greatly affected by resistance to water, and particularly in female swimsuits for swimming, a great difference in recording results depending on the magnitude of fluid resistance. Therefore, in swimsuits that have been conventionally used, research has been conducted on the shape of the material surface as well as the reduction of the resistance force by improving the shape. I'm trying to reduce the resistance. This is also true for speed skating and cycling where air resistance is a problem.

[0003]

However, in particular, the swimsuit for women has large openings in the neckline, back and sides, so that water and air enter through the openings during swimming.
This invasion of water or air vibrates the edge of the opening to form a turbulent flow, increasing the propulsion resistance with water. Further, there is a drawback that the water and air that have entered through the opening are retained between the swimsuit and the person, increasing the moving mass. As a result, these phenomena overlap and the propulsive resistance in water is large, and it is very difficult to shorten the competition record in the swimming competitions, where the physical strength of the athlete is approaching the limit.

The present invention has been made in view of the above-mentioned problems, and suppresses and rectifies the turbulence of the water flow on the surface of the swimsuit, and the water easily permeates the cloth of the swimsuit adjacent to the opening to prevent the water from staying. An object of the present invention is to provide a fluid resistance-reducing garment, which has a reduced resistance to water by blocking, and is suitable for speed competition including a swimsuit.

[0005]

SUMMARY OF THE INVENTION A fluid resistance-reducing garment according to the present invention comprises one or more of a collar, side and back openings of a garment such as a swimsuit sewn with various fiber material materials or sheet material materials. A plurality of base strips are arranged in the cloth body adjacent to each other in such a direction as to be substantially parallel to the flow direction of the fluid in use, and the base cloth strips project toward the surface of the cloth. It is the gist of the present invention to provide a dot row structure rectifying area in which a large number of fine projections are projected to form a row of many fine projections on the surface of the garment body. The base strip on which the fine protrusions to be formed are arranged is preferably a stretchable resin sheet of vinyl chloride, synthetic rubber, polyurethane, silicone or the like integrally formed on the cloth.

[0006]

Therefore, when this garment is constructed as a swimsuit, and when the user wears this swimsuit and swims, the water flows backward along the dot rows in the rectifying area of the dot row structure such as the oblique surface of the chest and the oblique surface of the lumbar spine. At the same time as sliding to, it is possible to positively intrude or drain water through the swimsuit body between the base strips.
There is also the discharge of water from the bottom part, which acts to bring the swimsuit body into close contact with the body surface of the swimmer. Also, in the dot row structure rectifying area such as the side sloped surface, the light distribution is inclined with respect to the flow direction of the water, but the elasticity of the base strip prevents the swimsuit body from stretching and It works to suppress the vibration. As a result, it becomes possible to reduce the propulsive resistance force in the water by the permeation of the running water in the dot row structure rectifying region and the rectifying action.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a fluid resistance reducing garment according to the present invention will be described below with reference to the drawings. The drawings show examples of swimsuits for women's swimming. The swimsuit body 1 is sewn with various stretchable fiber cloth materials or sheet cloth materials, and shoulder straps 4 extending from both sides of the neckline 2 and side cuts 3 and 3 are connected at the upper end of a back cut 5 that extends to the waist. Has been done. The bottom portion has a design in which a crotch cloth portion 7 is formed between the leg holes 6 and 6. Edge cloth 8 is sewn and trimmed at the edges of the neckline 2, the side cuts 5, 5, and the leg holes 6, 6, and the shoulder strap 4 also has the edge cloth 8.

On the surface of the body 1 of the swimsuit, an inverted triangular chest dot row structure rectifying area 9 is provided on the sloped surface (arrow A) of the chest, which is in contact with one edge of the edge cloth 8 at the center of the neckline 2. A side cut 3 is provided on the side face (arrow B), and an edge portion 8 is formed on the side face of the lumbar region (arrow C). 5 Inverted triangular back dot line structure rectifying area 11 with one edge in contact with the center edge cloth 8
Is provided.

Each dot row structure rectifying area 9, 10, 11
Is, as shown in an enlarged scale in FIGS. 2 and 3, vinyl chloride,
A large number of base strips 1 are formed on the surface of the cloth of the swimsuit body 1 by using a synthetic resin having elasticity such as synthetic rubber, polyurethane and silicone.
2, 12 ... Are adhered or integrally molded so as to be spaced apart from each other on the surface of the sheet portion 12 in a direction substantially parallel to the moving direction of water (row spacing L = 10.0 mm or less)
A large number of fine projections 13, 13 ... Are arranged on the surface of each base strip 12 (height H = 0.05 mm or more, pitch P = 0.1 m).
m or more), and the separation water passage portion 14 is configured between the base strips 12, 12.

According to the above construction, when swimming while wearing, the dot slope structure rectification areas 9 and 11 are respectively formed on the chest slope (arrow A) and the lumbar slope (arrow C) in the water flow direction. On the other hand, the water is in a slantingly opposed state, and the water in contact therewith slides rearward along the row of the fine projections 13, 13 ... Provided on the base strips 12, 12. In addition, the part (arrow A,
In C), the space between the base strips 12, 12, ...
4 makes it possible to positively invade or drain water through the swimsuit body 1, and there is also drainage of water from the bottom portion, so that the swimsuit body 1 is in close contact with the body surface of the swimmer. It acts to let you. Further, the armpit dot row structure rectifying region 10 provided on the armpit inclined surface (arrow B) is in a state in which light distribution is inclined with respect to the flow direction of water, but the base strips 12, 1
The elasticity of 2 ... Prevents the swimsuit main body 1 from expanding and operates so as to suppress the curling vibration of the edge.

As a result, the water that hits the part is the body 1 of the swimsuit.
The surface of the swimsuit can be slid backward along the row of the fine protrusions 13, 13 ..., and the swimsuit body 1 can be brought into close contact with the body surface of the swimmer. And these dot row structure rectification areas 9, 1
