Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swimming race for stabilizing the posture of an athlete during swimming, thereby reducing the form resistance on the human body of the athlete, enhancing the athletic function and increasing the propulsive force. About swimwear.

[0002]

2. Description of the Related Art In a swimming competition, an athlete who is swimming tries to keep his / her body straight and parallel to the water surface in order to reduce running resistance.
To maintain this straight posture requires abdominal and back muscle strength, but when these muscles become fatigued during the competition, it becomes difficult to maintain the posture. As a result, there is a problem that the portion from the waist to the leg sinks in water, and the morphological resistance increases.

[0003] In a conventional swimming suit for swimming, a competitor uses a so-called glider principle (that is, a principle in which a propulsive force is added so that a center of gravity is applied to a swimmer when swimming.
In the case of a crawl, the position where the hands enter and extend the water should be diagonally downward, not near the water surface, and the weight should be applied to the palm. In the case of swimming in the swimming method of (1), after entering the water, the face sinks because the hand reaches diagonally downward, and as a result, the trunk of the human body flexes forward, the back floats, and the legs sink. As a result, there is a problem that it becomes difficult for the competitor to maintain a basic posture necessary for swimming.

In order to solve such a problem, the inventor of the present application has conducted various experiments and studies on a swimsuit for swimming, and as a result, a tightening pressure of a certain pressure or more around the waist of a competitor has been obtained. Found that the posture of a competitor during swimming was stabilized when it acted.

[0005] However, in the conventional swimsuits for women, in the case of women's swimsuits, even if the waist is tightened to some extent, the tightening is for correcting the body shape and not for maintaining the posture of the competitor during swimming. Therefore, the degree of tightening was small and the stretching strength was low. Those with open backs hardly tightened the back of the waist. On the other hand, in the case of the men's swimwear, the pants-like one cannot tighten the upper part of the waist of the human body, and the one-piece type swimwear has a small degree of tightening of the waist of the human body.

The present invention has been made in view of such a conventional situation. When a swimmer wears a swimsuit, a constant tightening pressure is applied around the waist of a human body to sink the lower body of a swimmer during swimming. It is a main object of the present invention to provide a swimsuit for swimming that can prevent a swimmer and stabilize a posture of a competitor. Another object of the present invention is to further enhance the motor function and further increase the propulsion in such a swimsuit for swimming.

[0007]

According to a first aspect of the present invention, there is provided a swimsuit for swimming in which the tightening pressure around the waist of a human body of a swimsuit wearer is increased.
The waist of the swimsuit wearer is tightened at a constant pressure. Specifically, as described in the invention of claim 1, the waist of the swimsuit wearer does not wear the swimsuit on the pattern (that is, the swimwear wearer does not wear the swimsuit). The waist size is 45-55% of the nude size of the wearer's waist. As a result, the equivalent fastening pressure acts on the human body of the swimsuit wearer, and the posture of the athlete is maintained during swimming.

In the invention of claim 2, the first front body is formed, and in the invention of claim 4, the first back body is formed of a material having high elastic strength.

According to the third aspect of the present invention, the first front body is formed, and in the fifth aspect of the present invention, the first back body is formed of a material having the same elastic strength as other regions. .

A swimming suit for swimming according to a second invention is provided in claim 6.
As described in the inventions of (7) and (7), the angle between the first switching line from the back neck point to the rear center waist position and the second switching line from the waist position to the rear center hip position is set. By setting the angle to about 105 to 125 degrees, the upper part of the torso of the human body of the swimsuit wearer is turned backward, thereby assisting the spine and stabilizing the upper back waist. Here, the “back neck point” refers to a reference point on the swimsuit for swimming corresponding to the cervical vertebrae point of the human body.

As described above, according to the first and second aspects of the present invention, the posture of the athlete is held horizontally during swimming, so that the athlete can perform the basic posture (one head to one leg) required for swimming. It is easy to take a stick-like state where a nail passes). Thereby, the form resistance applied to the human body of the competitor is reduced, and further, the athlete's motor function is enhanced by applying force to the abdomen, so that the propulsive force is increased.

According to a third aspect of the present invention, there is provided a swimming suit for swimming.
As described in the tenth aspect, on the pattern, near the latissimus dorsi of the switching line from the vicinity of the back neck point to the waistline side via the latissimus dorsi, and from the waistline side to the upper part of the tongue. The "clearance amount" is given near the upper part of the tongue of the switching line leading to the crotch, and further on the side line of the second front body. Claim 1
"Front neck point" described in the invention of No. 0
Is a reference point on the swimsuit for swimming corresponding to the cervical fossa point of the human body.

[0013] The "clearance amount" as used herein refers to looseness (looseness) reserved for securing the amount of exercise of the human body, and refers to the length of the cloth extended along the twitch line. Means.

By providing such a "clearance amount" in the vicinity of the latissimus dorsi of the switching line or in the vicinity of the upper part of the tongue, the athlete's torso can be rotated while swimming while maintaining the tightness around the waist of the athlete. In this way, the swimmer can be prevented from twitching, and the contestant's rotation can be promoted. In addition, by providing a "clearance" on the side line of the second front body, there is room for expansion and contraction of the side line when the competitor breathes, and as a result, the feeling of pressure on the ribs due to tightening around the waist is reduced Thus, the difficulty of breathing can be reduced.

[0015]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIGS. 1 and 2 show a swimsuit for swimming according to an embodiment of the present invention.
(B) is a front view, a side view, and FIG.
(A), (b), and (c) are a top view, a rear view, and a bottom view of a swimsuit for swimming, respectively, FIG. 3 is a front view when a competitor wears a swimsuit, and FIG. FIG. 5 is a part diagram of the left half of the swimsuit before sewing, FIGS. 6 and 7 are diagrams for explaining the amount of clearance on the pattern, and FIG. 8 is a diagram for explaining the rotation form of the human body of the competitor. .

On the pattern (ie, the swimwear wearer
In a state where no clothes are worn (see FIGS. 1 and 2)
The waist size is W and the wearer's waist is nude.
To W ₀Then, the swimsuit for swimming according to the present invention is W = (0.45-0.55) × W₀ , While conventional swimwear for swimming
Is generally W = (0.80-1.00) × W₀ It has become.

That is, the waist size on the pattern is conventionally about 80 to about the nude size of the wearer's waist.
In contrast to the setting of 100%, in the present invention, about 4%
It is set to 5-55%.

As a result, the waist of the wearer is tightened when the swimsuit is worn, and a considerable tightening pressure acts on the human body of the swimsuit wearer. As a result, during swimming, the sinking of the lower body of the competitor is prevented, and the posture of the competitor is maintained straight.

In the front body of the swimsuit, as shown in FIG.
A first front body extending from the vicinity of the wearer's cervical fossa to the lower part of the waist line through the lower end of the sternum to the lower part of the rib and covering the area from the lower part of the waist line to the crotch through the groin (FIG. 1) ) Is formed of a material having a higher stretching strength than other regions. In addition, you may make it give a strong water-repellent process or a surface smoothing process to the cloth surface of a 1st front body. Further, the first front body may be formed of a material having the same stretching strength as the other regions.

In the back of the swimsuit, as shown in FIG.
The first back body (see FIG. 2) extends from near the cervical point of the wearer, across the latissimus dorsi muscle through the thoracic vertebra to the waistline side, and covers the area from the waistline side to the sacrum through the vicinity of the gluteal crest. , And is formed of a material having a higher stretching strength than other regions. In addition, you may make it give a strong water-repellent process or a surface smoothing process to the cloth surface of a 1st back body. Further, the first back body may be formed of a material having the same stretching strength as the other regions.

The swimsuit for swimming according to the present invention tightens the waist of the wearer, so that the hips larger than the circumference of the waist of the human body can pass through the waist portion of the swimsuit from the back neck point or the back so that the wearer can attach and detach the swimsuit. From somewhere between the neck point and the thoracic spine,
A fastener is provided between the waistline and the upper part of the sacrum (see FIG. 4). This fastener may be provided between the front neck point or any point between the front neck point and the lower end of the sternum, and to the lower abdomen below the waistline.

Further, in the swimsuit for swimming according to the present invention, as shown in FIGS. 5 and 6, on the pattern of the first back body 6, the first from the back neck point to the back center waist position. Angle θ between the switching line and the second switching line from the waist position to the rear center hip position
Is designed to be about 105 to 125 degrees, whereas in a conventional swimsuit, the angle θ is about 150 to 180 degrees.

Thus, in the present invention, when wearing a swimsuit,
The upper part of the torso of the wearer's torso from the waist is turned back, thereby assisting the back muscles and stabilizing the upper back waist.

In this way, when swimming, the posture of the competitor is kept straight, so that the competitor can maintain the basic posture necessary for swimming (a rod-like shape with one nail passing from head to leg). State). This reduces the form resistance on the athlete's body,
Strengthening the abdomen improves motor function and increases propulsion.

By the way, in a swimsuit for swimming, simply making the upper part of the torso of the human body from the waist to the back is simply required to pass through the waist position at the back center from the back neck point on the pattern. The distance to the hip position is shorter than the corresponding distance from the cervical vertebral point on the back of the human body to the hip through the waist. In this case, the cloth for the swimsuit is pulled up and down in the direction of the spine of the human body, and the cloth for the swimsuit floats from the human body in the concave portion of the spine on the back of the human body. As a result, water penetrates into the space between the recessed portion of the back spine and the swimsuit, which hinders the swimmer from swimming.

However, in the swimsuit for swimming according to the present invention,
The waist size on the pattern is set shorter than the nude size of the human waist so that the waist of the human body is tightened, so the fabric of the swimsuit is pulled around the waist of the human body and the spine on the back of the human body Swimsuit fabric tries to adhere to the dent. As a result, the fabric of the swimsuit follows the spine dent on the back of the human body, thereby preventing water from entering the space between the dent of the back spine and the swimsuit.

In the swimsuit for swimming according to the present invention, FIG.
And as shown in FIG. 6, the first and second back bodies 6,
On the pattern No. 7, the switching line 61 from the vicinity of the back neck point to the waistline side through the latissimus dorsi,
A “clearance amount” is provided at a position near the latissimus dorsi 71. In addition, "the amount of room" here means the looseness (looseness) of the cloth to keep for the momentum of the human body, and refers to the length of the cloth extended along the twitch line. Means.

By the way, at the time of swimming, as shown in FIG. 8, the rotation (inner rotation / external rotation) of the trunk of the human body, that is, the rolling motion, causes the vicinity of the base of the upper limb (near the shoulder) to the vicinity of the base of the lower limb (lower back). Spiral near the outer part).

However, in the present invention, the provision of the "clearance amount" increases the distance in the direction perpendicular to the switching line near the latissimus dorsi (see FIG. 6). Specifically, as the distance in the perpendicular direction, first and second
For each of the back bodies, a length of about 1 to 2 cm is preferable. With such a “clearance amount”, the tension of the swimsuit fabric in the direction of the base of the upper limb and the position of the back center of the waist is reduced. As a result, helical convulsions between the vicinity of the base of the upper limb and the vicinity of the base of the lower limb due to the rotation of the trunk can be alleviated, and the torsion of the trunk can be promoted.

In this way, the athlete can propel the body by applying the limb movement to the torsion movement and the forward and backward bending movement of the trunk while maintaining the tightening around the waist. it can.

In the swimsuit for swimming according to the present invention, FIG.
Also, as shown in FIG. 6, on the pattern of the rear pants 9, the “clearance amount” is also provided at a position near the upper groin portion of the switching line 91 from the waist line side to the sacrum through the upper gluteal portion. .

This "clearance amount" increases the distance in the direction perpendicular to the switching line 91 near the upper part of the lord. Specifically, the distance in the perpendicular direction is preferably about 1 to 2 cm. Thereby, the tension of the swimsuit fabric in the direction of the base of the lower limb and the position of the back center of the waist is reduced. With such a "clearance amount", the rear body 6,7
"Clearance" provided near the latissimus dorsi of the switching lines 61 and 71
In conjunction with this, the helical convulsions that occur from the vicinity of the base of the upper limb to the vicinity of the base of the lower limb during the rotation of the trunk are further alleviated, and the torsion of the trunk is further promoted.

The tension of the swimsuit cloth is reduced in the direction perpendicular to each of the switching lines by the "clearance amount" provided on the switching lines 61, 71, 91, and thereby, the direction of the back center position of the waist of the swimsuit. As a result, the fabric of the swimsuit is more likely to adhere to the recessed portion of the spine on the back of the human body.

By the way, inhalation of respiration is caused by contraction of the diaphragm,
It is performed by raising the rib cage due to contraction of the external intercostal muscles and expanding the chest circumference by raising the ribs. However, simply tightening the waist of the human body simultaneously tightens and presses the lower ribs, making breathing difficult.

However, according to the present invention, the switching lines 61, 71
Of the swimsuit passing near the latissimus longens the circumference parallel to the waist of the swimsuit, thereby relaxing the tension of the swimsuit fabric and passing near the latissimus Relax the lower ribs around the swimsuit waist. In this way, the wearer does not have difficulty breathing while maintaining the tightness of the waist portion.

Further, according to the present invention, as shown in FIGS. 5 and 7, on the pattern of the second front body 2, from the vicinity of the front neck point to the lower side of the rib through the lower end of the sternum, the lower part of the waist line is lowered. When the intersection of the leading switching line 21 and the waist line is defined as a base point a, the intersection of the side line 22 and the waist line is defined as a side waist point b, and the lower end of the second front body 2 is defined as a vertex c. Substantially triangular region abc consisting of waist point b and vertex c
Is rotated to the first front body 1 side around the base point a, so that the "clearance amount" d is provided on the side line 22. The “clearance amount” d is set to, for example, about 0.5 cm.

As described above, by providing the "clearance amount" to the side line 22 of the second front body 2, the side line is not affected by the movement of the thorax due to the contraction of the external intercostal muscle during the athlete's breathing. There is a margin for expansion and contraction, and as a result, for the `` tightening around the waist '' which is a main characteristic part of the swimming suit of the present invention, the feeling of pressure on the ribs is reduced, and the difficulty of breathing is reduced. You.

Further, by the rotation of the substantially triangular area abc, a new switching line 21 extending from the vicinity of the front neck point to the vertex c 'through the base point a as shown by the dashed line in FIG. So that the first
The vicinity of the waist line on the pattern of the front body 1 is more closely attached to the wearer's body, and the waist is more effectively tightened.

[0039]

As described above, according to the swimsuit for swimming according to the present invention, the posture of the competitor can be kept straight, the form resistance of the human body can be reduced, the motor function can be improved, and the propulsive force can be increased. Can be done. As a result, the time can be improved. Further, according to the present invention, by providing the `` clearance amount '', while maintaining the tightened state around the waist of the athlete, preventing the swimsuit from twitching due to the rotation movement of the athlete's trunk, The athlete's rotation movement can be promoted, the feeling of pressure on the ribs due to the tightening around the waist can be reduced, and the breathing operation is not hindered.
