TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a swimsuit for swimming related to resistance to water or air or a sportswear for low fluid resistance related to sportswear.
[0002]
[Prior art]
In competition or short distance running on land, the competition has recently been for 1/100 second, and the resistance of water or air has become a considerable problem. That is, when an object moves underwater or in the air, compression or expansion of water or air, movement and vibration of water, adsorption of water or air, etc. occur at the tip, surface and rear, causing the object to stay at that position. Various forces act as shown. Karman vortices are one of them, and they are generated behind the object as it travels and are not desirable for sucking the object.
[0003]
That is, since a force is generated in the object in a direction that hinders its movement, movement in water or in the air becomes very difficult due to thrust.
Since swimming also moves the body underwater, not only applies various forces similar to when moving objects underwater, but it also moves each part to obtain thrust, so it has very complicated elements in it. .
[0004]
Conventionally, there has been a swimsuit for swimming in which a small uneven line or a row of small projections are provided on a part of the front and rear body, but the effect has not been improved as a swimming swimsuit in which the direction is constantly changed. In recent years, some swimsuits have been roughened in order to promote water peeling, but this has not been expected to have a definite effect at this time.
[0005]
[Problems to be solved by the invention]
The present invention provides a new swimsuit for swimming in which the resistance is minimized by actively controlling the water instead of the conventional swimming suit for uncertain water resistance as described above. The purpose is to provide a swimsuit for swimming that is easy to come out.
[0006]
At the same time, it is not only for swimwear for swimming but also for fighting air resistance, for short distance running on land such as 100 meters running, distance sports such as skating and skiing, or for sports such as various cycling and skiing downhill jumping It is also intended to provide hardware.
[0007]
[Means for Solving the Problems]
The swimsuit for swimming according to the present invention is a swimsuit that presents a wet suit that is sewn with cut pieces cut from a stretch fabric material. Are bonded or welded to the left body on the left body, the right body on the right body, and a plurality of ribs (preferably about 0.1 mm to 8.0 mm) integrally or at appropriate intervals. The gist is that the right or left arm is adhered or welded to the right or left winding.
[0008]
In addition, it is also preferable to form a plurality of narrow ribs lower than the height of the narrow ribs at appropriate intervals along the spiral narrow ribs.
It is also preferred to have a height between mm and 2.0 mm.
[0009]
It is possible to arbitrarily form the arrangement of these two types of narrow or narrow low ribs, and to form both or one of these two types intermittently.
[0010]
The narrow ribs or the narrow low ribs can be formed not in a straight line but in a gentle wave shape or in a sawtooth shape.
[0011]
Also, these two types of ribs need not be provided at appropriate portions as desired. That is, for example, the left arm and the right arm, the inflated shin, and the like are formed only of a stretch fabric material, and neither of the two types of spiral narrow ribs may be provided.
Similarly, the inner crotch portion may not be provided with either of the two types of spiral narrow ribs. Not only when it is used, but also it is not a stretch fabric material to avoid friction, that is, a non-stretch fabric material may be applied).
Furthermore, the above-mentioned swimsuit may be configured to present a wet suit without sleeves.
[0012]
In particular, in the case of a swimsuit, the above-mentioned swimsuit can have a sleeveless structure, or the legs can be formed only at a portion above the thighs or in a high-leg shape.
[0013]
It is also conceivable that each cut piece of the swimsuit is cut into a spiral shape and one or both of the two types of spiral ribs are provided along the sewing portion.
[0014]
Furthermore, the swimsuit may be constituted only by a portion below the waist, and a swimsuit for men can be obtained.
[0015]
In addition, it is also preferable that the two types of ribs are formed at substantially equal intervals or / and substantially in parallel with each other or a combination thereof.
[0016]
Instead of the two types of spiral narrow ribs, one or both of the two types of ribs in the longitudinal direction or the longitudinal direction can be formed at a desired portion in the swimsuit.
[0017]
In addition, the above-mentioned swimsuit for swimming can be applied to various sportswear as clothes for short-distance running on the land, distance sports such as skating and skiing, or various types of cycling and skiing downhill and jumping. .
