技用衣服を提供しようとするものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to provide a skating competition garment which is useful for skating competitions such as speed skating and short track in order to reduce air resistance exerted on players and improve records.

が考えられる。2. Description of the Related Art There are the following types of resistance received by athletes in skating competitions. First, when air enters through the opening of the clothes, it stays in the clothes and acts like a parachute and becomes a resistance. for that reason,
In order to reduce the air resistance applied to clothes, first, it is considered that the shape of the clothes is taken into consideration to prevent air from entering the clothes.

ことになる。Next, as the resistance received by the athlete, there are surface friction resistance and shape resistance (pressure resistance). Among them, the surface frictional resistance may be unevenness on the cloth surface of the garment, and the frictional resistance can be reduced by increasing the smoothness of the cloth surface of the garment. However, the surface friction resistance is only 10% of the total resistance, and the shape resistance accounts for 90% of the total resistance. Therefore, reducing the form resistance is more effective in reducing the total resistance than reducing the frictional resistance.

らったものである。As a method of reducing the form resistance, there is a method of adjusting the air flowing on the body surface (the cloth surface of clothes) while gliding on ice so as to smoothly flow the air. As an example of such an invention, Japanese Patent Laid-Open No. 10-
No. 140407 was raised, which aims to rectify air.

張る抵抗は減少する。On the other hand, the air flowing on the body surface while gliding on ice flows along the head, shoulders, arms, legs, and rear of the back, but at the slightly rear end of the maximum width portion of the above-mentioned human body parts. It separates from the body surface and becomes a backflow vortex behind the competitor. This vortex creates a force that pulls the athlete backwards, which provides resistance to the athlete moving forward. Therefore, if the separation position of the air flowing on the body surface is shifted backward,
The resulting vortices are smaller and the resistance pulling the competitor backwards is reduced.

る。FIG. 17 schematically shows this. As shown in FIG. 17A, the air flowing on the body surface is separated from the body surface at the slightly rear end of the maximum width portion of each part of the human body. This is a peeling point 5. A vortex 6 that flows backward is generated behind the separation point 5 and acts as a resistance that pulls the player backward.

減少するのである。Therefore, it is conceivable to shift the peeling position rearward to suppress the generation of the backflow vortex 6 and to reduce the resistance pulling the player backward. As such a method, as shown in FIG. 17B, it is conceivable to dispose a continuous or discontinuous projection 2 slightly in front of the separation point 5 so as to be nearly perpendicular to the air flow. When such a protrusion is provided, the air hitting the protrusion becomes a turbulent flow and causes the turbulence of the air to be separated, so that the separation point of the air is displaced backward. As a result, the resistance pulling the competitor backward is reduced.

However, since the above inventions and inventions are only provided with the linear protrusions, the turbulent flow is less likely to occur. In addition, since the protrusion itself also becomes a resistance (the resistance reduction value is represented by the difference between the resistance reduction value due to turbulence and the resistance value of the protrusion itself), the resistance reduction is not as expected. Therefore, the present invention is intended to exert the maximum resistance reduction effect in skating competition clothes by efficiently generating turbulence.

The resistance value was measured with the wind at a speed of 17 m / s, which is equivalent to the maximum speed of the skating competition, and with nothing attached first. Then 4 for wind direction
A projection 2 having a diameter of 2 mm and a height of 1 mm was arranged at a position of 5 °, and a resistance value was measured by applying a wind having a wind speed of 17 m / s to calculate a resistance coefficient. Then, staggered 2mm apart into 2 rows, 3

であると考えられる。FIG. 13 is a graph showing the resistance coefficient.
Shown in. Note that 0 represents the resistance value when no protrusion is attached. Looking at this graph, the resistance coefficient keeps decreasing until the 15th column, but the resistance coefficient gradually increases from the 16th column to the 20th column. The reason for this is 1
For the protrusions up to the fifth row, the resistance reduction value due to turbulence is larger than the resistance value of the protrusion itself, but from the 16th row onwards, the resistance value of the protrusion itself is larger than the resistance reduction value due to turbulence. This is probably because the generated turbulence does not have the action of reducing the resistance.

同様の突起を１列ずつ増やして抵抗係数を測定した。Therefore, it was further verified how the projections in the 16th row and thereafter should be formed. (Experiment 2) The conditions are the same as those described above, and the projections in the 16th row have a diameter of 2 mm and a height of 0.5 mm. The resistance coefficient was measured. Next, the 17th row also has a diameter of 2 mm and a height of 0.5.
The resistance coefficient was measured by arranging mm projections at 2 mm intervals, and thereafter, the resistance coefficient was measured by increasing the same projection one by one.

を有しないためであると考えられる。The results are shown in FIG. Looking at this, the resistance coefficient further decreases in the 16th to 18th rows, but gradually increases in the 19th and 20th rows. This is because the resistance reduction value due to turbulence can be kept larger than the resistance value of the projection itself by lowering the height of the projection after the 16th row. It is considered that this is because the resistance value of itself becomes larger than the resistance reduction value due to the turbulent flow, or the generated turbulent flow does not have the action of reducing the resistance.

The dot height from the 9th row to the 24th row was 0.3 mm. As in Experiments 1 and 2, the test pieces were arranged in a zigzag pattern at intervals of 2 mm, and the resistance coefficient was measured while increasing one row at a time. The result is shown in FIG. Looking at this, the resistance coefficient gradually decreases from the 19th to 21st rows, but from 22 to 2
The fourth row is gradually rising. It is considered that this is because the height of the protrusion is lowered, and the resistance coefficient is lowered for the same reason as described in Experiment 2.

る。From the above experimental results, as described in claims 4 and 5, the heights of the respective projections 2 constituting the projection group decrease as the air flow goes from the windward side to the leeward side. It can be seen that the resistance can be further reduced if the height of the projection 2 is reduced stepwise.

Arrange as they become, or as shown in Fig. 7,

In this way, the same resistance reduction effect can be obtained by making the sizes of the respective projections 2 smaller in a group.

Independent microscopic projections on the surface of the base material, the projections are in the frontal region of the head, the back of the shoulders in the lengthwise direction, and the thighs, thighs, and upper arms in the direction parallel to the horizontal plane. The staggered arrangement reduces the form resistance experienced by the athlete due to the turbulence created by the protrusions.

It is expressed by equation ( 2) . Note that ρ is the air density, Cd is the resistance coefficient, and V is the velocity. From this equation, it can be said that the speed is proportional to the square root of the reciprocal of the resistance coefficient. For example, if the resistance coefficient decreases by 5%, the speed increases by 2.5%.
It can be said that the time will also be 2.5% faster. It can be said that such reduction of resistance greatly contributes to improving the record of skating players.
