  As described above, the swimming swimsuit has been conventionally improved in various ways, but has the following problems to be solved.

  In the swimsuit described in Patent Document 1, since the arrangement of joints such as seams with respect to the water flow during swimming is not taken into consideration, water flow resistance in water may increase depending on the arrangement of the joints. In addition, since a member having a large elongation stress is not disposed on the front side member, the trunk is not supported from the front side, and it is difficult to maintain a flat posture in water.

  Even in the swimsuit described in Patent Document 2, since the arrangement of joints such as seams with respect to the water flow during swimming is not taken into consideration, the water flow resistance in water may increase depending on the arrangement of the joints. Further, the trunk portion is not provided with strong tightening portions and weak tightening portions, so that it is easy to maintain a flat posture in water, and it is impossible to realize both easy attachment / detachment and ease of movement of the leg portions.

  Even in the swimsuit described in Patent Document 3, since the arrangement of joints such as seams with respect to the water flow during swimming is not considered, water flow resistance in water may increase depending on the arrangement of the joints. Further, although a portion corresponding to a strong tightening portion is provided around the region of the abdomen and the lower back, it is not supported from the upper body to the lower body, and a flat posture maintenance in water is not sufficiently performed. In addition, since a strong tightening portion is continuously provided around the pelvis, it cannot be easily attached and detached.

  In order to solve the above problems, the present invention is a swimming race swimsuit capable of reducing resistance in water by allowing the joint to follow the flow of water during swimming, preferably by providing a strong tightening portion in the trunk. It is possible to provide a swimsuit that can easily maintain a flat posture and can easily attach and detach and can easily move a leg by providing a weak tightening portion.

  The present invention is a swimming race swimsuit made of stretchable fabric, and has fabric pieces extending continuously from the both side parts including the upper anterior iliac crest to the upper end and the lower end of the swimsuit along the body length direction.

  Further, the present invention is a swimming swimsuit made of stretchable fabric, a piece of fabric that extends continuously from the both side parts including the upper anterior iliac crest to the upper and lower ends of the swimsuit along the body length direction. The dough piece is formed in a pair of left and right so as to follow the flow of water during swimming, and is formed so as to bend outward from the periphery of the clavicle through the periphery of the nipple and along the lower end of the rib. The present invention relates to a competitive swimsuit.

  Further, the present invention is a swimming swimsuit made of stretchable fabric, a piece of fabric that extends continuously from the both side parts including the upper anterior iliac crest to the upper and lower ends of the swimsuit along the body length direction. The dough piece is formed in a pair of left and right so as to follow the flow of water during swimming, and passes through the upper anterior iliac crest and the greater trochanter to the hem along the outer thigh The present invention relates to a spats-type swimsuit characterized by being formed as described above.

  The swimsuit of the present invention is composed of at least two kinds of stretchable fabrics having different tightening forces, and is strongly tightened to a part including the central part of the body width direction of the body before the swimsuit, at least a part covering the lower abdomen from the abdomen.

FIG. 5C is a schematic side view for explaining a case where the posture in which the waist in swimming falls from the horizontal position is observed from the side, and FIG. 5D is an explanatory diagram showing the projected area of the body with respect to the traveling direction in water during the same posture. is there. FIG. 5E is a schematic side view for explaining a case where a posture in which a leg in swimming falls from a horizontal position is observed from the side, and FIG. 5F is an explanatory diagram showing a projected area of the body with respect to a traveling direction in water at the same posture. is there.

  In solving the problems of the present invention, the present inventors first visualized the flow of water around the human body during swimming. The experiment was conducted using a circulating water tank using a life-size adult model. In consideration of actual swimming, the adult adult body model is performed in two states: the head and part of the body are above the surface of the water and the state where the body is completely submerged. Visualization includes the tuft method and dye injection method. Was used. As a result, especially on the front of the body that is susceptible to water resistance, a flow that flows along the length of the chest and a curve that curves to both sides around the lower ribs, and a flow that runs along the length of the body occur, and curves to both sides. It was found that this flow further flows to the body side around the waist, merges with the flow from the upstream of the back surface around the pelvis, and flows downstream in the body length direction. FIG. 4 shows an example of a schematic diagram visualizing the flow of water during swimming. FIG. 4A shows the flow of water in a front view of a swimsuit according to one embodiment of the present invention, FIG. 4B shows the flow of water in the side view, and FIG. 4C shows in the rear view. It shows the flow of water. It was found that the flow was particularly fast at the waist. In the two states of the life model on the water surface, there was a difference in water flow from the back of the scapula to the waist, but almost no difference was seen on the front of the body. For this reason, when the joint is provided so as to be perpendicular to the flow of water, the convex portion formed on the surface of the swimsuit hinders the flow of water and leads to an increase in resistance. It can be seen that the provision is effective in reducing the resistance.

  Therefore, in the present invention, the fabric is made of stretchable fabric, and has fabric pieces extending continuously from the both side portions including the upper anterior iliac crest to the upper and lower ends of the swimsuit along the body length direction. The pair is formed as a pair of left and right so that the water follows the flow of water while swimming, passing from the lower clavicle through the papilla, curved outward along the lower end of the rib, through the upper anterior iliac crest, greater trochanter Competitive swimming that can reduce resistance due to the joint line from the chest to the waist and the outer surface of the thigh, which is most susceptible to water resistance, because it is formed to reach the hem along the outer thigh Provide swimwear. Although not particularly limited, for example, a half-suit type swimsuit can be configured as the swimsuit of the embodiment.

  Further, the present invention comprises a fabric having stretchability, and has fabric pieces extending continuously from the both side portions including the upper anterior iliac crest to the upper and lower ends of the swimsuit along the body length direction, The dough piece is formed in a pair of left and right so as to follow the flow of water during swimming, and it is formed so as to bend outward from the periphery of the clavicle to the periphery of the nipple and along the lower end of the rib. Provided is a swimsuit that can reduce resistance due to a joint line between a chest and a waist that is susceptible to water resistance. Although not particularly limited, for example, a high-cut swimsuit for girls can be configured as the swimsuit of the embodiment.

  Further, the present invention comprises a fabric having stretchability, and has a fabric piece extending continuously from the both side portions including the upper anterior iliac crest along the body length direction to the upper end and the lower end of the swimsuit, The dough piece is formed as a pair of left and right so as to follow the flow of water during swimming, and it is formed so as to reach the hem along the outer side of the thigh through the upper anterior iliac crest and the greater trochanter Thus, a spats-type swimming race swimsuit that can reduce the resistance caused by the joint line from the waist to the outer surface of the thigh, which is susceptible to water resistance.

  Next, the present inventors have intensively studied in order to solve the problem that the shape resistance is increased and the exercise performance is deteriorated by lowering the position of the waist and legs from the position of the upper body during competitive swimming. If you become tired as the race progresses, such as during swimming, the tempo of the kick may drop, and your body may stand with your hips lower than your upper body. When the body stands, the position of the leg also goes down. FIG. 5A is a schematic side view illustrating a case where a flat posture in swimming is observed from the side, and FIG. 5B is an explanatory diagram illustrating a projected area of the body with respect to a traveling direction in water at the same posture. FIG. 5C is a schematic side view for explaining a case where the posture in which the waist in swimming falls from the horizontal position is observed from the side, and FIG. 5D is an explanatory diagram showing the projected area of the body with respect to the traveling direction in water during the same posture. is there. FIG. 5E is a schematic side view for explaining a case where a posture in which a leg in swimming falls from a horizontal position is observed from the side, and FIG. 5F is an explanatory diagram showing a projected area of the body with respect to a traveling direction in water at the same posture. is there. As shown in FIGS. 5A and 5B, when the body is in a flat posture (horizontal posture), the projected area in the traveling direction in water is small, and the shape resistance due to water is small. However, as shown in FIGS. 5C-F, when the waist position or the leg position is lowered, the projected area in the traveling direction in water increases, and the shape resistance due to water increases. Therefore, when the waist position or the leg position is lowered, the stroke is shortened and the speed is lowered, resulting in a problem that the exercise performance is lowered. For example, when the position of the waist or leg is lowered with respect to a flat posture, the shape resistance becomes about twice or more. In order for the athlete to maintain a flat posture as shown in FIG. 5A, it is important to squeeze the chest inward and increase the abdominal pressure. In order to assist this, it is effective to hold at least both the front side of the body from the abdomen to the lower abdomen and the back side of the body from the waist to the buttocks with strong tightening fabrics. The method of continuously covering the periphery of the pelvis with a strong tightening fabric is also effective for maintaining the posture, but there are drawbacks that hinder the kicking operation and require labor for attachment / detachment. In particular, the greater trochanter is the starting point for kicking, so weakening the tightening force leads to ease of movement. In addition, on the back side, a strong tightening fabric is disposed at least from the waist to the back of the thigh, thereby assisting hamstrings that are easily fatigued and preventing the lower body from lowering. Furthermore, by placing strong tightening fabric on the front of the body above the abdomen, it is possible to obtain the effect of assisting the sense of squeezing the chest inward, and by placing strong tightening fabric on the back of the body above the waist, Since the fabric is pressed with strong tightening fabric, the effect of stabilizing the posture can be obtained.

  Accordingly, the swimsuit according to the present invention is preferably made of at least two kinds of stretchable fabrics having different tightening forces, and covers at least a part including the central portion in the body width direction of the front body of the swimsuit, at least from the abdomen to the lower abdomen. Apply strong tightening fabric to the entire back part, or at least the part covering the waist part from the hips to the buttocks or at least the waist part to the back of the thigh. By placing a weak tightening fabric on the back, it prevents the lowering of the position of the hips and legs, keeps the body flat, and makes it easy to kick without disturbing the movement of the hip joint while stabilizing the trunk Can be made. Furthermore, it is possible to facilitate attachment and detachment by arranging weak tightening fabrics on both side portions.

  The type of the swimsuit is not particularly limited, and may be any of a half-suit type swimsuit, a men's spats-type swimsuit, a girls' high-cut swimsuit, and the like. The men's spats-type swimsuit may be half spats.

  In the half-suit type swimsuit or the men's spats-type swimsuit, the maximum width of the strong tightening fabric disposed at a part including the center part in the body width direction of the front body of the swimsuit, at least the part covering the lower abdomen from the abdomen, It is preferable that it is 42 to 60% with respect to the hip width of this swimsuit. If it is less than 42%, it tends to be difficult to obtain a sufficient trunk stability effect. If it exceeds 60%, attachment / detachment tends to be difficult, and further improvement of the trunk stability effect tends not to be observed. From the viewpoint of achieving both a trunk stability effect and ease of attachment / detachment, it is more preferably 45 to 55%.

  In the high-cut swimsuit for girls, the maximum width of the strong tightening fabric disposed in a part including the central part of the body width direction of the front body of the swimsuit, at least the part covering the lower abdomen from the abdomen is the hip width of the swimsuit. It is preferable that it is 60 to 70% with respect to the width. If it is less than 60%, it tends to be difficult to obtain a sufficient trunk stability effect, and if it exceeds 70%, it tends to be difficult to attach and detach, and there is a tendency that no further improvement in trunk stability effect is observed.

  The calculation method of the hip width is as follows: half-suit type swimsuits have a width of 7 cm from the inseam, and the pattern size of men's spats type swimsuits has a pattern size of 8 cm from the inseam. The width and width of the high-cut type swimsuit for girls is the width of the pattern that connects the vertices of the right and left footsteps. The maximum width of the strong tightening fabric disposed in a part including the central portion of the front body width direction, at least the portion covering the lower abdomen from the abdomen (hereinafter also referred to as the maximum width of the strong tightening fabric of the front body) is The pattern size of the part is used.

In addition, the weak tightening fabric 32 can facilitate the kicking operation without hindering the movement of the hip joint, and can facilitate attachment and detachment.

The swimsuit for swimming according to the present invention can be fitted to a human body by using a stretchable fabric. The material of the fabric used in the swimsuit for swimming according to the present invention includes synthetic fiber multifilament yarns such as polyamide, polyester, and polypropylene, or the intersection of these synthetic fiber multifilament yarns and polyurethane elastic yarns. Knitted fabrics or woven fabrics made of knitted or woven fabrics can be used. In particular, swimsuits for swimming often place importance on easiness of movement, and as a material form, a knitted fabric obtained by knitting synthetic fiber multifilament yarn and polyurethane elastic yarn is more preferable. In addition, as the knitted fabric form, a single circular knitted fabric that is a circular knitted fabric, a double circular knitted fabric, a tricot fabric that is a warp knitted fabric, or a raschel fabric can be used, but stretch properties that affect the ease of movement. Tricot fabric is more preferable from the viewpoint of fabric thinness. When a stronger support force is required, the material form is preferably a fabric using a composite yarn obtained by covering a polyurethane elastic yarn with a synthetic fiber multifilament yarn for warp and weft.

  The fabric used in the swimsuit according to the present invention desirably has water repellency. The water repellent used in the swimsuit according to the present invention can be appropriately selected from various water repellent treatment agents conventionally used, such as silicone water repellents and fluorine water repellents. Further, the treatment agent used in the water repellent part of the swimsuit according to the present invention is not limited to the name of the water repellent, and the weight of the swimsuit in water is substantially reduced by making the fabric less likely to contain water. Any treatment agent may be used as long as it is reduced. For example, a treatment agent such as a printing agent or a sealing agent may be used.

  The fabric used for the swimsuit according to the present invention preferably has as little surface frictional resistance as possible. For this purpose, it is preferable to perform surface smoothing, riblet processing, or the like.

  Among them, the method for applying surface smoothing to the fabric is as follows.

  As used herein, the term “smoothing” refers to a processing means that changes the surface more smoothly than before the processing by crushing the uneven shape caused by loops on the surface of the knitted fabric with heat or pressure. Among these, from the viewpoint of processing stability and productivity, calendar processing is preferable as a specific means for smoothing processing.

As the processing machine, an ordinary heating roll and a paper roll, or a calendar processing machine made of a cotton roll, or a calendering process using a plate-like material can be used, and when a heating metal roll is used, it should be a mirror surface roll. preferable. In addition, when using as a knitted fabric for swimming wear, for example, the calendering condition is about 1 to 60 t / cm in linear pressure and the roll temperature is about 130 to 250 ° C. with respect to the knitted fabric width of 100 to 220 cm. It is preferable.

  As another smoothing process, a transfer printing machine having a heated metal roll and a leather belt can be used. These smoothing conditions may be set as appropriate depending on the type of knitted fabric, surface irregularity, texture, and the like.

  As a method for further reducing the surface frictional resistance as compared with a smooth surface, a resistance reducing effect is exhibited by forming fine grooves or ridges along the body length direction on the fabric surface.

  The strong tightening fabric used in the swimsuit according to the present invention is preferably such that the stress at the time of 50% elongation is 130 to 300% with respect to the weak tightening fabric. If the stress at 50% elongation is less than 130%, the difference in tightening force cannot be experienced and the effect of maintaining a flat posture in water may not be exhibited. Moreover, when the stress at the time of 50% elongation exceeds 300%, there is a risk of feeling uncomfortable when wearing a swimsuit. The measuring method is based on the JIS L 1096.88.14.1A method (constant speed extension method), and the measurement conditions are a test piece size of 5 cm in width, a length of 30 cm, a distance between chucks of 20 cm, and a tensile speed of 20 cm. Measured at / min.

  The strong tightening fabric is not particularly limited, but may be composed of a single fabric or a double fabric obtained by superimposing two fabrics. For example, the second fabric can be superimposed on the first fabric constituting the swimsuit to make a double fabric. The first and second fabrics may be the same fabric or different fabrics.

  Since the cloth piece in the present invention continuously extends from the upper end and the lower end of the swimsuit, in the body width direction, the front center part side and the side part side are joined to other members, and each joining line is Are formed substantially in parallel through the dough piece passing through the body part. At that time, it is desirable that each joint line is provided so as to follow the direction of water flow in each body part because the effect of reducing the resistance is greater.

  The method for joining the fabric pieces can be selected from methods such as sewing with a sewing machine, ultrasonic bonding, and bonding a reinforcing seam tape to the bonding portion.

  Examples of the present invention will be described below, but the present invention is not limited thereto.
