Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a technique for reducing the resistance of a swimsuit, and reduces the resistance to water during swimming during swimming competition, and the resistance to air during speed skating, cycling competition, etc. Especially, the fluid resistance reduction suitable for speed competition clothes. It's about clothes.

[0002]

[Prior art]

 It has been found that swimming competitions that compete for speeds of 1 / 100th of a second are greatly affected by resistance to water, and especially in female swimsuits for swimming, large differences in fluid resistance make a significant difference in records. Therefore, in the swimwear that have been used so far, research has been conducted on the morphology of the material surface as well as the reduction of the drag force by improving the morphology, and in the technology of materials, it is generally necessary to make the surface as smooth as possible to achieve fluid contact with water. I'm trying to reduce the resistance. This is also true for speed skating and cycling where air resistance is a problem.

[0003]

[Problems to be solved by the device]

 However, in particular, women's swimwear have 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, which increases the propulsive resistance with water. Further, there is a drawback that water and air that have entered through the opening are retained between the swimsuit and the person, increasing the amount of movement. As a result of these phenomena, thrust resistance in the water is large, and it is very difficult to shorten the competition record in swimming events where the physical strength of the athlete is approaching its limit.

The present invention has been made in view of the above problems, and suppresses and rectifies the turbulence of the water flow on the surface of the swimsuit, and the water easily permeates through the fabric of the swimsuit adjacent to the opening to retain the water. It is an object of the present invention to provide a fluid resistance-reducing garment, which has a reduced resistance to water by blocking water and is suitable for speed competition including swimming suits.

[0005]

[Means for Solving the Problems]

 The fluid resistance-reducing garment according to the present invention is used for the body of a garment such as a swimsuit sewn with various fiber material or sheet material, which is adjacent to one or more of the collar, side and back openings. A large number of base strips are arranged in the fabric so as to be substantially parallel to the flow direction of the fluid at the time, and a large number of fine projections are formed on the surface of the fabric with respect to each of the base strips. The gist of the present invention is to provide a dot row structure rectifying area in which a large number of rows of fine projections are formed on the surface of the body of the garment so as to project. The arranged base strips are preferably stretchable resin sheets such as vinyl chloride, synthetic rubber, polyurethane and silicone integrally molded with the cloth.

[0006]

[Action]

 Therefore, when this garment is constructed as a swimsuit and water is worn while swimming, water slides backward along the dot rows in the dot row structure rectification area such as the oblique surface of the chest and the oblique surface of the lumbar spine. At the same time as moving, it is possible to positively allow water to enter or drain through the swimsuit body between the base strips, and also to let the swimsuit body adhere to the swimmer's body surface due to the water drainage from the bottom part. Act on. Also, in the dot row structure rectification area such as the side sloped surface, the light distribution is inclined with respect to the flow direction of water, but the elasticity of the base strip prevents the swimsuit body from stretching and It operates to suppress the vibration of the fan. 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.

[0007]

【Example】

 Hereinafter, an embodiment of a fluid resistance reducing garment according to the present invention will be described with reference to the drawings. The figure shows an example of a women's swimsuit. The swimsuit body 1 is sewn with various kinds of elastic fiber sheet material or sheet material, and the shoulder straps 4 extending from both sides and the side cuts 3 and 3 of the neckline 2 are at the upper end of the back cut 5 that extends greatly to the waist. It is connected. Further, the bottom portion has a design in which a crotch cloth portion 7 is formed between both leg holes 6 and 6. A hem 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 hem cloth 8.

On the surface of the swimsuit body 1, an inverted triangular chest dot row structure rectifying region 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 on the facing surface (arrow B) is provided with an inverted triangular side row dot row structure basin 10 that is in contact with one edge of the edge cloth 8 at the center, and a back cut is made on the oblique surface (arrow C) of the lumbar vertebra. (5) An inverted triangular back dot row structure rectifying area 11 having one edge in contact with the central edge cloth 8 is provided.

As shown in the enlarged view of FIGS. 2 and 3, each dot row structure rectifying area 9, 10, 11 is made of a synthetic resin having elasticity such as vinyl chloride, synthetic rubber, polyurethane and silicone. A large number of base strips 12, 12 ... Are adhered or integrally molded to the surface of the fabric of the main body 1 so as to be spaced apart on the surface of the sheet portion 12 in a direction substantially parallel to the moving direction of water (row spacing L = 10). ..) and a plurality 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 mm or more). A separation water passage portion 14 is configured between them.

According to the above configuration, when swimming while wearing, the inclined surface of the chest (arrow A) and the oblique surface of the lumbar vertebra (arrow C) have the dot row structure rectification areas 9 and 11 in the water flow direction, respectively. The water is in a slantingly opposed state, and the water in contact therewith slides rearward along the rows of the fine projections 13, 13 ... Provided on the base strips 12, 12. Further, in the portions (arrows A, C), since the base strips 12, 12, ... Are separated water passage portions 14, 14, ... Therefore, invasion or drainage of water through the swimsuit body 1 is positively performed. The swimsuit body 1 is brought into close contact with the body surface of the swimmer due to the drainage of water from the bottom portion. Further, the side-dot-column structure rectifying region 10 provided on the side-side inclined surface (arrow B) is in a state in which the light distribution is inclined with respect to the flow direction of water, but the elasticity of the base strips 12, 12 ... The swimsuit main body 1 is prevented from stretching and acts to suppress the vibration of the edge.

As a result, the water hitting the part slides backward on the surface of the swimsuit body 1 along the rows of the fine protrusions 13, 13 ..., and can bring the swimsuit body 1 into close contact with the body surface of the swimmer. Wear. Then, it becomes possible to reduce the propulsive resistance force in the water by the permeation of the flowing water in the dot row structure rectifying regions 9, 10 and 11 and the rectifying action. That is, in the structure of the dot row structure rectifying regions 9, 10 and 11, a row of projections is formed on the surface of the swimsuit body 1 and is composed of a large number of fine projections 13, 13 ... Which are substantially parallel to the moving direction of water. Therefore, the water is caused to flow in the projection row direction and the turbulent flow in the different direction disappears, so that the rectifying effect can be exerted and the turbulent flow in the rear can be suppressed.

Although the swimsuit for women's swimming has been described in the above embodiment, the swimsuit for boys and the swimming cap may have the same structure.

Further, although the swimsuit is disclosed in the above description of the embodiments, the present invention is similarly applied to clothes used in various speed competitions where air resistance is a problem such as speed skating and bicycle competitions. It goes without saying that it is possible to obtain the same fluid resistance reducing action as in the aforementioned swimsuit.

[0014]
