Description

  The present invention relates to a swimsuit having a low fluid resistance.

In swimming, a swimsuit with low water resistance is required. Water resistance is divided into water flowing on the body surface, fluid friction resistance of the body or swimsuit, and shape resistance depending on the body shape. The conventional swimsuit pays attention to reducing the frictional resistance of the material (for example, Patent Documents 1 to 3), and has not been devised to reduce the shape resistance having a high ratio among the fluid resistances.
In order to reduce the fluid friction resistance, it is necessary to cover the whole body with a material having a low fluid friction resistance as much as possible. Therefore, even in a men's swimsuit, a swimsuit in which the upper body and the lower body are connected has been provided. However, the upper body part and the lower body part are connected, and in particular, the movement of the upper body may be hindered. Therefore, in a swimsuit in which the upper body part and the lower body part are connected, it is required that the fluid frictional resistance is lowered and that it is easy to move. In particular, players who usually wear spats-type swimsuits often do not wear a type that covers the upper body because of difficulty in movement. For this reason, a swimsuit of a type that covers the upper body while having a feeling of wearing a spats type is required.

  In order to reduce the shape resistance, it is required to eliminate as many convex parts of the body as possible, such as the swelling of the buttocks. In addition, as a factor for increasing the shape resistance during the swimming action, there is a bending of the lower body with respect to the upper body that is particularly seen during fatigue. All of these increase the projected area as viewed from the direction of body movement and increase the shape resistance. From the above, in order to reduce the shape resistance, it is necessary to stabilize the trunk of the body and maintain the limbs and trunk in parallel with the flow of water.

However, the conventional example has a problem in satisfying the function of stabilizing the trunk and facilitating movement while lowering the fluid frictional resistance.
Japanese Patent No. 2715088 Japanese Patent Application Laid-Open No. 2004-292962 WO2007 / 142232 Specification

  In order to solve the above-mentioned conventional problems, the present invention has a low fluid resistance, a part of the back body of the upper body part is divided, the waist part is appropriately tightened to stabilize the trunk, and parallel to the flow of water. Provide a swimsuit that satisfies the functions of maintaining limbs and trunks and the ability to move easily.

  The swimsuit of the present invention is a swimsuit that is worn in a state where the body part that covers the upper body and the spats part that covers the lower body are joined at either part, and is in close contact with the surface of the wearer. The inner fabric on the skin side and the outer fabric on the outside, the lower end of the inner fabric is joined to at least a part of the spats, the upper end of the inner fabric is not joined to the outer fabric In addition, at least a part of the lower end of the outer fabric is joined to the front portion of the spats, and an opening / closing mechanism is provided from the center of the lower end of the outer fabric to the middle of the upper end along the spine. .

  Another swimsuit of the present invention is a one-piece type swimsuit in which a body part covering the upper body and a region covering the lower body are continuously formed, and is worn in a state of being in close contact with the surface of the wearer, the body part Is composed of an inner fabric on the skin side and an outer fabric on the outside thereof, the lower end of the inner fabric is joined to at least a part of the region covering the lower body, and the upper end of the inner fabric is joined to the outer fabric. In addition, a region in which the outer fabric covers the body part and the lower body is continuously formed, and an opening / closing mechanism is provided from the center of the lower end of the body part outer fabric to the middle of the upper end along the spinal column. It is characterized by that.

  In the swimsuit of the present invention, the body part is composed of the inner fabric on the skin side and the outer fabric on the outside thereof, the lower end of the inner fabric is joined to at least a part of the spats, and the upper end of the inner fabric is the outer fabric. Is not joined, and at least a part of the lower end of the outer fabric is joined to the front part of the spats, and an opening / closing mechanism is provided from the center of the lower end of the outer fabric to the middle of the upper end along the spine. The fabric part extending from the upper part to the neck part of the opening and closing mechanism and the synergistic effect of providing the opening part eliminates the tension of the back part and moderately tightens the abdomen, thereby stabilizing the waist and waist be able to. As a result, the fluid resistance as a whole is small, the waist portion is tightened to stabilize the body trunk, and the function of being easy to move can be satisfied.

  In the swimsuit of the present invention, the body part covering the upper body and the spats part covering the lower body are joined and joined at either part. This applies not only to women's swimsuits but also to men's swimsuits. Moreover, it wears in the state closely_contact | adhered to the wearer's surface. Furthermore, the body part is composed of an internal fabric on the skin side and an external fabric on the outside thereof. That is, it has a double structure. The lower end of the inner fabric is joined to at least a part of the spats, the upper end of the inner fabric is not joined to the outer fabric, and at least a part of the lower end of the outer fabric is a front part of the spats. And has an opening / closing mechanism from the center of the lower end of the external fabric to the middle of the upper end along the spinal column. As a result, the fluid resistance is low, the waist portion is appropriately tightened to stabilize the trunk of the body, and the function of being easy to move can be satisfied.

  A collar is attached to the body part, and a shoulder part is preferably formed so as to cover more than half of the clavicle. Covering the part where the fluid resistance during swimming is high with a cloth to reduce the surface frictional resistance and holding the shoulder muscles with the surface, the unevenness of the skin surface of the shoulder part is suppressed compared to the case where a string-like fabric is placed. The shape resistance can be reduced and the feeling of pressure applied to the shoulder can be reduced, the cloth can be stretched and moved easily, and water can be prevented from entering the swimsuit.

  The shape of the lower end of the external fabric is preferably a semicircular shape that is convex toward the head. The lower back (upper waist) can be opened for easy movement of the waist.

  It is preferable that the body part and the spats part are joined at a waist part, and rubber is arranged at the joint part. This can tighten the waist and reduce water flow resistance. In addition, it is possible to provide a feeling of wearing close to spats for players who normally prefer spats.

  The swimsuit of the present invention is preferably basically composed of a hydrophilic stretch fabric portion and a non-hydrophilic stretch fabric portion. As an example, the hydrophilic stretchable fabric portion is disposed at a position covering the neck circumference, the pectoral muscle part, the back part, the lower abdominal muscle part, the upper hip part, and the thigh inner front part. As an example, the non-hydrophilic stretchable fabric portion is disposed at a position covering the waist including the abdominal and back muscles, the large buttocks to the back of the thigh, and the thigh to the side of the waist. The hydrophilic stretch fabric part of the back part is placed on the back part so as to cover the non-hydrophilic stretch fabric part of the back muscle part, and can be opened and closed at the lower end of the back from the lower part of the back neck along the spinal cord An open / close mechanism is provided. The opening / closing mechanism uses a fastener, for example, and is opened and closed from the lower end of the back to the lower part of the back neck. A cloth is provided around the neck, and the cloth is placed on the shoulder to reduce the feeling of biting in the shoulder strap.

  This swimsuit can reduce fluid resistance by disposing a hydrophilic fabric in a portion where friction with water occurs. Also, by placing elastic fabric on the waist including the abdominal and back muscles, the waist is properly tightened to stabilize the body trunk and maintain the limbs and trunk in parallel with the water flow Can be arranged. Moreover, a leg can be made easy to move by arrange | positioning non-hydrophilic elastic cloth from the large buttocks to the rear inner part of the thigh. In addition, the hydrophilic fabric part of the back part is placed on the back part so as to cover the non-hydrophilic stretch fabric part of the back muscle part, so that it can be opened and closed from the bottom of the back neck along the spinal cord at the lower end of the back By providing the opening / closing mechanism, the pulling resistance of the waist fabric part which becomes an obstacle when the water is stroked can be reduced, and it can be converted into a forward propulsion force accordingly.

  In the present invention, the main part means a main part covering the body, and means a part corresponding to the body and spats.

  The stretch fabric used in the present invention is preferably a one-way or two-way woven or knitted fabric containing elastic yarn. The elastic yarn is preferably at least one selected from a polyurethane elastic yarn and a polyester elastic yarn. This is because it is highly stretchable and suitable for sports clothing. The elastic yarn may be used as a bare yarn, in alignment with a non-elastic yarn (rigid yarn), or may be used as a covered yarn whose surface is coated with polyester fiber or nylon fiber. .

  The inelastic yarn is preferably polyester (polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, etc.) fiber yarn, polyamide fiber yarn, acetate fiber yarn, cotton fiber yarn, rayon fiber yarn, ethylene vinyl alcohol fiber yarn, or the like. Of these, polyethylene terephthalate (PET) fiber yarns that are thermoplastic, have good heat setting properties, and are hydrophobic are preferred.

  A woven fabric or a knitted fabric can be used as the fabric. As the woven fabric, plain weave, oblique weave, satin weave, altered plain weave, altered oblique weave, altered satin weave, alter weave, crest weave, single layer weave, double structure, multiple structure, warp pile weft, weft pile weave, entanglement There are weaving etc. Of these, plain weave is excellent in texture and strength for sports applications. Usually, a woven fabric is composed of warp and weft. When a rigid yarn such as a polyester fiber yarn is used, there is almost no elongation in the warp or weft direction.

  Examples of the knitted fabric include round knitting, weft knitting, warp knitting, pile knitting, etc., flat knitting, tengu knitting, rib knitting, smooth knitting (double-sided knitting), rubber knitting, pearl knitting, denby knitting, cord knitting, atlas knitting, There are chain tissue, insertion tissue, etc. Since the knitted fabric is basically composed of a loop, even when a rigid yarn such as a polyester fiber yarn is used, when stress is applied, the loop is deformed to cause elongation.

The fabric weight is preferably in the range of 100 to 400 g / m ² . Within this range, problems such as sheer do not occur, it is suitable for aesthetics, and there is no feeling of weight and wearability is high.

  The stretchability of the fabric is preferably a knitted fabric in which at least one selected from the warp direction and the weft direction has an elongation rate under a load of 4.9 N (500 gf) measured according to JIS 1096 of 5 to 150%. If it is in this range, it follows the movement of the body and is highly wearable.

  As the hydrophilic fabric, as disclosed in Patent Document 3, the water-absorbing gel adsorbing particles in which the water-absorbing gel resin is adsorbed on the porous inorganic particles are fixed to at least a part of the surface of the stretchable fabric together with the binder resin. (Hereinafter also referred to as “hydrophilic treatment part”) can be used. The hydrophilic treatment portion may be partially printed on the surface of the fabric or may be immersed on the entire surface. In the case of partial printing, the other part may be a non-processed area or may be painted separately from the water repellent part.

  In the present invention, in order to create an “almost close contact” state, the peripheral direction is 50% or more and 110% or less, more preferably 70% or more and 95% or less, and the length is 75% or more and 100% with respect to the naked size of the human body. % Or less, more preferably 85% or more and 100% or less to form the underpants. Of course, since the size of the human body varies among individuals, the above ratio is a guide. More specifically, the size is determined according to the JASPO standard.

  The swimsuit of the present invention is also useful as a one-piece type swimsuit. Moreover, it is suitable as a swimsuit of a half suit, a long suit, or a full suit. It is particularly suitable for swimsuits for swimming.

  Relatively high stretch fabric (high power material fabric, also referred to as “strong tightening material” hereinafter) and relatively low stretch fabric (hereinafter also referred to as “weak tightening material”) must be integrated by sewing. Is preferred. However, in the case of a weft knitted fabric, it can be integrally knitted as will be described later.

  The strong tightening material and the weak tightening material of the present invention are stretch materials, and the elongation rate of the weak tightening material is 2 in the length direction with respect to the strong tightening material when 4.9 N (500 gf) is applied in the width of 5 cm. It is preferable that the range is twice or more. Further, it is preferable that the extension ratio of the weak tightening material in the length direction is 1.3 times or more with respect to the strong tightening material when 17.7 N (1800 gf) is loaded in the width of 5 cm. Here, the length direction is used to indicate the length direction in the finished product regardless of the background direction of the fabric.

In order to obtain such stretch characteristics of each portion, as will be described later, for example, when an elastic yarn is used as a constituent yarn of a knitted fabric or a woven fabric, the following means can be taken as an example.
(1) The composition ratio of the elastic yarn is made higher in the strong tightening material than in the weak tightening material.
(2) Increase the fineness of the elastic yarn in the strong tightening material compared to the weak tightening material.
(3) In the case of a woven fabric, the warp and / or weft density is increased, and in the case of a knitted fabric, the knitting density is increased as compared with a weak tightening material.
(4) A woven fabric or a knitted fabric is produced with a high tension material having a higher tension of the elastic yarn than a weak tension material.
(5) Fabrics or knitted fabrics are manufactured by making the fabric thicker than the weakly tightened material.

  More preferably, the stretch material of the present invention is at least one fabric selected from a two-way stretch knitted fabric and a two-way stretch woven fabric that expand and contract in the machine direction and the transverse direction.

  The two-way stretch knitted fabric or woven fabric may include polyester fiber yarns and elastic yarns as main component constituent yarns, or nylon fiber yarns and elastic yarns as main component constituent yarns. As another configuration, cotton (cotton) and elastic yarn may be used as the main component constituting yarn. Here, the main component constituting yarn means that the total of both components is 80% by weight or more. When polyester fiber yarn is used, it is easy to dry even with sweat. When nylon fiber yarn is used, the knitted fabric has a soft touch.

  The knitted or woven fabric may have any structure. As the woven fabric, a plain weave, a diagonal weave, and a satin weave, which are generally well known, may be a changed weave. Further, a knitted fabric knitted by a Russell warp knitting machine generally well known as a knitted fabric, a knitted fabric knitted by a tricot warp knitting machine, a knitted fabric knitted by a knit weft knitting machine, or the like may be used. For example, a knitted fabric having a half structure knitted by a tricot warp knitting machine or a knitted fabric having a power net structure knitted by a Russell warp knitting machine can be used. As the knitted weft knitted fabric, any structure such as a flat knitting (tengu knitting), a rubber knitting, a pearl knitting, and a smooth knitting (double-side knitting) may be used. The knitted fabric knitted by the knit weft knitting machine may be a knitted fabric knitted by a circular knitting machine or a flat knitting machine. In the case of the weft knit, it is also possible to integrally knitting the weak tightening material and the strong tightening material without requiring sewing. For example, there is an apparatus called “FIRST-X” of a flat knitting machine (Shimae Seiki Seisakusho), which can be used to knitting the body part and the sleeve part at the same time to produce a knitted product without sewing.

  In addition, a combination of strong and weak materials is seamlessly knitted into a tubular shape with a device called "seamless body inner knitting machine" under the full computer control of Santoni, Italy. It is also possible.

  The woven fabric or knitted fabric preferably uses at least a part of elastic yarn having elasticity such as polyurethane yarn.

  The elastic yarn is preferably at least one selected from a polyurethane elastic yarn and a polyester elastic yarn. This is because it is highly stretchable and suitable for sports clothing. The elastic yarn may be either a bare yarn (bare yarn) or a covered yarn whose surface is coated with polyester fiber or nylon fiber.

  A fabric using a high crimped false twisted yarn such as polyester or nylon which has been subjected to high crimped false twisting to give stretchability is also possible for at least part or all of the fabric. It is also possible to simply use a plurality of the stretchable knits. Furthermore, the stretchable knitted fabric is laminated into a two-layer laminate fabric, and a stretchable polyurethane sheet is sandwiched between the stretchable knitted fabric and laminated into three layers. A layer laminate fabric can also be used.

  Next, as a method of giving the fabric material a “strong” or “tight” tightening force to obtain a strong tightening material and a weak tightening material, a mixture ratio of polyurethane yarn and high crimped false twisted yarn (hereinafter referred to as stretch yarn) is used. The “large” and “small” of each can give the fabric material a “strength” tightening force. As a method of changing the blend ratio, changing the thickness of the stretch yarn to “thin and thin” gives the blend ratio “large” or “small”. There is a way to get a “large” or “small” mix ratio. It is also possible to change the knitting density to “sparse / dense” when the mixing ratio of the stretchable yarn is constant. In addition, using a fabric with different types of stretch yarns, using a laminated fabric and a non-laminated fabric, or changing the number of layers of the same fabric will also give the fabric a “strength” tightening force. It is possible to have it.

  The “strength” tightening force of the strong tightening material and the weak tightening material can be confirmed by the magnitude of the stretch rate of the fabric at a constant load. That is, a fabric having a strong tightening force has a low elongation rate, and a fabric having a weak tightening force has a high elongation rate.

  In the present invention, the tightening force refers to the resistance of the material to elongation.

  The measuring method of the stretch ratio representing the stretchability and the tightening force is a TENSILON universal type tensile tester (UTM-III-200, manufactured by Toyo Baldwin), the tensile strength is 20 cm / min, and the size of the sample fabric is The width was 5 cm, the length was 30 cm, and the holding interval was 20 cm. The weight for measuring the tightening force was 4.9 N (500 gf), the weight for measuring the stretch property was 17.7 N (1800 gf), and the measurement was made in the direction of the background of the fabric material. The stretch ratio used in the description of the present invention is a measurement result by this measurement method.

  In the swimsuit according to the present invention, the strong tightening material and the weak tightening material may be integrated by sewing or bonding to form an exercise garment.

  Examples of sewing methods include lock stitching, chain stitching, one-needle overlock, two-needle overlock, and sewing with a sewing machine that forms a seam such as a flat seamer. It is not limited to. However, it is desirable to adopt a one-needle overlock, a two-sewing overlock, and a flat seamer that have a stretch property and are less likely to cause discomfort when worn.

  As the bonding method, paste two types of fabrics (members) that you want to integrate, melt them with heat, and paste them with a heat-meltable seam tape made of resin, such as polyurethane or silicone, which penetrates and solidifies after cooling. Although there is a thermocompression bonding method in which the fabric can be bonded by sandwiching between the fabrics and heat-pressing, it is desirable to provide a stretch property similar to sewing so as to eliminate the uncomfortable feeling at the time of wearing.

  This will be described below with reference to the drawings.
