Description

Sportswear

The present invention relates to sportswear worn in a state of being in close contact with the surface of the wearer.

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. Conventional swimsuits focus on reducing the frictional resistance of materials (for example, Patent Documents 1 to 3), and no effort has been made to reduce the shape resistance, which has a high ratio among fluid resistances.

To lower the shape resistance, it is necessary to eliminate as many convex parts of the body as possible, such as the buttocks and bulges of women's breasts. 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 required to suppress the swelling of the body and the bending of the lower body. In order to suppress bending of the lower body, it is necessary to design so that tension is applied mainly in the extension direction of the hip joint. In order to realize this, conventionally, a tension is applied in the extending direction of the hip joint by covering with a strong tightening material and a weak tightening material. Moreover, in the spats for athletics, covering the buttocks with a surface-like strong tightening material supports the operation of pulling the ground, that is, the extending operation of the hip joint (Patent Document 4). However, even in these conventional examples, there is a problem in satisfying the function of suppressing the bending of the lower body with respect to the upper body and smoothing the body convex part and the function of being easily moved.

Japanese Patent No. 2715088 Japanese Patent Laid-Open No. 2004-292962 WO2007 / 142232 Specification JP 2005-146450 A

In order to solve the above-described conventional problems, the present invention provides sportswear that has a function of suppressing bending of the lower body with respect to the upper body, smoothing the convex part of the body, and satisfying an easy-to-move function.

The sportswear of the present invention is a sportswear that includes a stretchable base fabric and a partially non-stretchable or low stretchable material, and is worn in close contact with the surface of the wearer. The low stretch material is divided into a region A that covers at least the back of the waist, a region B that includes the bulge portion of the buttocks, and a region C that includes the rear surface of the thigh, and reinforces the tension in the hip extension direction. And

The sportswear of the present invention includes a stretchable base fabric and a partially non-stretchable or low-stretch material, and the non-stretchable or low-stretch material includes at least a region A covering the back of the waist, and a region including a bulge portion of the buttocks B and the area C including the rear surface of the thigh are divided and arranged to reinforce the tension in the hip extension direction, so that the function of lifting the rear surface of the thigh from the buttocks is exerted and the bending of the lower body with respect to the upper body is suppressed. In addition, the function of smoothing the body convex portion and the function of being easy to move can be satisfied.

In other words, non-stretch or low stretch material is divided into areas A to C to reinforce the tension in the hip extension direction and to lift the back of the thigh from the buttocks. Can be suppressed. In addition, even if a non-stretchable or low stretchable material is tensioned by operation, it itself hardly or not stretches. For this reason, the tension applied to the region made of the non-stretchable or low stretchable material becomes a force in the direction of the skin and presses the body convex portion. Regions A to C are portions where muscles swell, and a non-stretchable or low-stretch material is disposed in these portions, thereby exhibiting a function of smoothing the body convex portion. In particular, regions B and C are sites where muscle groups that contribute to the extension of the hip joint, such as the greater gluteal muscle and hamstrings, respectively, increase the intramuscular pressure by compressing these regions, and effectively extend the hip joint direction. Make it easy to exert muscle strength. As a result, the function of lifting the rear surface of the thigh from the buttocks can be exhibited, the lower body bending with respect to the upper body can be suppressed, the body convexity can be smoothed, and the functions that can move easily can be satisfied.

FIG. 9A is a front view of a one-piece type swimsuit according to another embodiment of the present invention. FIG. 9B is a rear view of the same.

The sportswear of the present invention includes a stretchable base fabric and a partially non-stretchable or low-stretch material, and the non-stretchable or low-stretch material includes at least a region A covering the back of the waist and a bulge portion of the buttocks. The area B and the area C including the rear surface of the thigh are divided and arranged. Between the areas A to C and other areas, the stretchable base fabric is arranged to reinforce the tension in the hip joint extension direction. To do.

The non-stretchable or low-stretch material is a fabric using inelastic yarn, such as polyester (polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, etc.) fiber yarn, polyamide fiber yarn, acetate fiber yarn, cotton fiber yarn, There are woven fabrics using rayon fiber yarn, ethylene vinyl alcohol fiber yarn and the like. Of these, polyethylene terephthalate (PET) fiber yarns that are thermoplastic, have good heat setting properties, and are hydrophobic are preferred. 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.

Another example of the non-stretchable or low-stretch material is a knitted fabric using inelastic yarn. 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. However, since the dimensional change is slight, such a knitted fabric is included in a non-stretchable or low-stretch material.

Still another example of the non-stretchable or low-stretch material is a sheet obtained by impregnating or pasting an elastomer resin or rubber into a woven fabric or knitted fabric. The stretchable base fabric may be impregnated or pasted with an elastomer resin or rubber. Elastomer resins include urethane elastomers, soft vinyl chloride elastomers, styrene elastomers, olefin elastomers, ester elastomers, amide elastomers, chlorinated polyethylene elastomers, Syn-1,2-polybutadiene elastomers, Trans-1 , 4-polyisoprene elastomer, fluorine elastomer and the like. These are described in “Plastic Data Book”, December 1, 1999, published by the Industrial Research Council, pages 854-910. Examples of rubber include silicone rubber, fluorine rubber, urethane rubber, synthetic rubber, and natural rubber.

A non-stretchable or low-stretchable material may be arranged stepwise or in an inclined manner around the non-stretchable or low-stretchable material. Moreover, it is preferable that the shape of the non-stretchable or low-stretchable material arranged stepwise or inclined is a circle, an ellipse, a rounded polygon or a line.

The non-stretch or low stretch material may be sewn to the stretch base fabric. This may be a method of turning back, that is, making a hole in the fabric and sewing another fabric, or a method of sewing another fabric on the stretchable base fabric. Alternatively, a sheet obtained by impregnating or pasting the elastic base fabric with an elastomer resin or rubber may be further sewn.

Still another example of the non-stretchable or low-stretch material is one in which the stretchable base fabric is embroidered with nonelastic yarn. Examples of the inelastic yarn include 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, and the like. Of these, polyethylene terephthalate (PET) fiber yarns that are thermoplastic, have good heat setting properties, and are hydrophobic are preferred.

It is preferable that the elongation at the time of 4.9N (500 gf) load measured by JIS1096 of the non-stretchable or low stretchable material is 0% or more and less than 10% in the long axis direction of the body. Thereby, the reinforcing effect from the hips of the human body to the rear surface of the thigh can be further increased.

The basis weight of the non-stretchable or low stretchable material 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.

In the present invention, it is also preferable to dispose the non-stretchable or low-stretchable material in a continuous region C ′ covering not only the rear thigh but also the inner thigh. Thereby, the function of lifting the rear surface of the thigh from the buttocks can be further strengthened, and further, by covering the hip adductor muscle group, an increase in shape resistance due to the abduction of the hip joint can be suppressed.

Furthermore, in the present invention, it is also preferable to dispose the non-stretchable or low-stretchable material not only in the rear thigh but also in a continuous region C ″ that covers the thigh. The function of lifting the back of the thigh from the thigh can be further strengthened, and further, the swelling of the thigh can be suppressed and the resistance of water can be lowered.

In the present invention, it is also preferable to dispose the non-stretchable or low stretchable material separately in a region D that covers the quadriceps. Thereby, the swelling of the thigh can be suppressed and the resistance of water can be lowered.

It is preferable that the shape of the divided part of the region A and the region B is an inverted C shape when viewed from the rear surface in the vertical direction. As a result, the function of lifting the back of the thigh from the buttocks can be further strengthened, and a function that does not hinder the movement of the human body can be obtained.

It is preferable that the shape of the division part of the region B and the region C is a C shape or a shape in which the central part is recessed when viewed from the longitudinal rear surface. Similarly to the above, the function of lifting the rear surface of the thigh from the buttocks can be further strengthened.

The elastic base 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 stretchable base fabric is preferably a fabric (woven fabric or knitted fabric) having an elongation rate at a load of 4.9 N (500 gf) measured by JIS1096 of 10% or more in the longitudinal direction of the body. If it is in this range, it follows the movement of the body and is highly wearable. In particular, it is preferable that the stretchable material disposed in the portion where the regions A to D are divided is a material that is easily stretched. This is because the materials in the areas A to D are difficult to stretch, so that a balance is obtained. Basis weight of the stretchable base fabric is preferably in the range of 100 ~ 400g / ^{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.

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 sportswear. 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 sportswear is suitable for sports spats. Specifically, it is suitable for half spats, long spats and the like. The sportswear may be a one-piece type such as a half suit, a long suit or a full suit covering the upper body.

In the present invention, a V-shaped or U-shaped non-stretchable or low-stretch material may be further reinforced at the shin. Thereby, bending of a knee can be prevented underwater and a flat stream line can be maintained.

The one-piece type swimsuit may be reinforced by arranging non-stretch or low stretch materials on the left and right chest and abdomen. As a result, bending from the abdomen to the chest can be prevented and a flat stream line can be maintained. The non-stretch or low stretch material of the abdomen may be a single sheet or may be divided into a plurality of sheets.

A slit may be provided in the non-stretchable or low stretchable material. Since it stretches in this way, there is an advantage that the wearability and the feeling of wearing can be kept good, breathing becomes easy, and the lifting effect of the body can be kept.

The sportswear is suitable for sportswear including swimwear, ball games or track and field events, jumping events and throwing events. It is particularly suitable for swimsuits for swimming. That is, in the event that the hip joint extension operation leads to the performance, the sportswear is expected to increase the performance. For example, in athletics, it is effective for short-distance events where jumping power is important, jumping events, and throwing events.

In short-distance running, the hip joint is extended at the stage of jumping the ground, at the crossing in the jumping event, and at the throwing event, when throwing the throwing object. At this time, the foot is in contact with the ground in each operation, and a large force is exerted in the direction of extending the hip joint due to the contraction of the greater gluteal muscle etc., so the tension in the hip extension direction by the sportswear increases the performance Can be made.

Also, the present invention is effective in ball games such as basketball and volleyball that perform jumping motions intermittently. In these events, an effect can be expected for the same reason as described above when jumping.

Furthermore, an effect can be expected when landing. That is, in the landing motion, the hip joint is temporarily bent, but at this time, muscles such as the greater ankle muscle are exerting force in the hip joint extension direction while being stretched, and this function is one factor that reduces the impact of landing. It has become. The tension in the hip joint extension direction by the sportswear assists this function and can reduce the strain on the muscles when landing.

Furthermore, the above sportswear is also effective as a clothing for competitions such as speed skating and skiing performed in a crouching posture with the hip joint bent. In such a competition, it is necessary to maintain a posture in which the hip joint is always bent. At this time, muscles such as the greater calf muscle continuously exert their muscular strength in the hip joint extension direction. The tension in the hip extension direction according to the present invention also assists such a function and can reduce the burden on the muscles used for posture maintenance.

Especially in speed skating, the effect can be expected even in the ice making phase as in the above-mentioned short-distance running.

This will be described below with reference to the drawings. FIG. 1A is a front view of a swimming half spats 10 according to an embodiment of the present invention, and FIG. 1B is a rear view thereof. In FIG. 1A-B, the main part is constituted by the stretchable base fabric (1). A region A (2a, 2b) that covers at least the back of the waist with a non-stretch or low stretch material, a region B (3a, 3b) that includes the bulges of both hips, and a region that includes the rear surfaces of both thighs It is divided into C (4a, 4b). Reinforces the tension in the hip extension direction, demonstrates the function of lifting the back of the thigh from the buttocks, suppresses bending of the lower body with respect to the upper body, has the function of smoothing the convex part of the body, and satisfies the functions that are easy to move Can be made.

The stretchable base fabric (1) and the areas A to C can be formed by placing a non-stretchable or low-stretchable sheet on the stretchable base fabric (1) and fixing it by sewing, or by using an adhesive. You may do it. As another means, a non-stretchable or low-stretchable sheet having thermoplasticity may be fixed by thermocompression bonding. As another means, positions corresponding to the areas A to C of the stretchable base fabric (1) may be cut out and a non-stretchable or low stretchable sheet may be sewn. As another means, an elastomer resin or rubber may be impregnated or affixed on the stretchable base fabric (1). As another means, the stretchability may be reduced by embroidering the positions corresponding to the areas A to C of the stretchable base fabric (1).

FIG. 2A is a front view of a swimming half spat 11 according to another embodiment of the present invention, and FIG. 2B is a rear view thereof. 2A and 2B, the main part is constituted by the stretchable base fabric (1). Then, a region A (2a, 2b) covering at least the back of the waist with a non-stretch or low stretch material, a region B (3a, 3b) including the bulges of both hips, and the rear surfaces of both thighs Are divided into a region C ′ (5a, 5b) including the inner side of the thigh and a region D (7a, 7b) covering the quadriceps. As a result, the effect of lifting the legs can be further strengthened, and the increase in shape resistance due to abduction of the hip joint by covering the hip adductor muscle group is suppressed, and further, the swelling of the thigh is suppressed. , Water resistance can be lowered.

FIG. 3A is a front view of a swimming half spats 12 in still another embodiment of the present invention, and FIG. 3B is a rear view thereof. The difference from FIGS. 1A and 1B is that the non-stretchable or low stretchable material is a region C ″ (6a, 6b) in which the thigh is wound, and the rest is common. In addition, the effect of lifting the legs can be further strengthened, and the increase in shape resistance due to the abduction of the hip joint by covering the hip adductor muscle group is suppressed, and further, the swelling of the thigh is suppressed, Resistance can be lowered.

FIG. 4A is a front view of a swimming half spats 13 in still another embodiment of the present invention, and FIG. 4B is a rear view thereof. 2A-B is that there is no region D (7a, 7b) covering the quadriceps.

Next, the muscles of the lower body of the human body will be described with reference to FIG. In the buttocks, there is the greater gluteal muscle 20, with the middle gluteal muscle 21 above it and the upper part of the iliac ligament in the lateral portion. Reference numeral 23 denotes an upper adductor upper portion. Reference numeral 24 denotes the contraction direction of the greater gluteus muscle 20.

FIG. 6 is an explanatory view showing the extending direction of each region by applying the swimming half spats 10 of FIG. 1 to the buttocks of the human body shown in FIG. In FIG. 6, 31 is the direction of tension applied to the stretchable base fabric (1) between the region A (2a, 2b) and the region B (3a, 3b), 32 is the contraction direction of the greater gluteal muscle, 30 is The direction of the resultant force of the tension direction 31 and the greater gluteal muscle contraction direction 31 is shown. Reference numeral 33 denotes the skin extension direction between the region B (3a, 3b) and the region C (4a, 4b). Since the shape of the divided part of region A (2a, 2b) and region B (3a, 3b) is inverted, the direction of tension generated by the fabric and the direction of muscle contraction approximate, It can be seen that it is easy to lift the butt and press the bulge. Moreover, since the division | segmentation part of the area | region B (3a, 3b) and the area | region C (4a, 4b) is C-shaped, it turns out that the room which the stretchable base fabric (1) extends is large.

FIG. 7 is an explanatory view showing the extension direction of the half spats for swimming in the comparative example. In FIG. 7, 41 is the direction of tension applied to the stretchable base fabric (1) between the region A (2a, 2b) and the region B (3a, 3b), 44 is the extension line, and 42 is the greater gluteal muscle The direction of contraction, 40 indicates the extension line. Reference numeral 43 denotes a skin extension direction between the region B (3a, 3b) and the region C (4a, 4b). Since the shape of the divided part of the region A (2a, 2b) and the region B (3a, 3b) is C-shaped, the direction of tension generated by the fabric and the direction of muscle contraction cannot be approximated. It can be seen that it is difficult to lift the bottom part and it is difficult to hold the bulge part. Moreover, since the division | segmentation part of the area | region B (3a, 3b) and the area | region C (4a, 4b) is reverse C shape, the room (arrow 43) where the elastic base fabric (1) extends is small.

The muscle fiber running direction of the greater gluteal muscle, which is the main muscle for hip extension, is downward with an angle of about 30 to 70 degrees as it goes outward from the center in the width direction as seen from the longitudinal rear surface of the body. (See FIG. 5). That is, it has a C shape when viewed from the rear in the vertical direction. This direction is the same as the direction in which the tension is exerted by the contraction of the greater gluteal muscle. On the other hand, in a preferable example of the present invention, the shape of the divided portion of the region A and the region B is a reverse C shape when viewed from the rear surface in the vertical direction. That is, it has an angle approximately perpendicular to the contraction direction of the greater gluteal muscle. For this reason, the tension due to the stretch of the fabric accompanying the hip joint extension is more likely to occur in the direction from the upper end of the region B to the lower end of the region A, and approximates the direction of tension exerted by the greater gluteal muscle, so that it is easier to lift the buttocks, It is easier to hold the bulge of the bottom (see FIG. 6). On the contrary, when the shape of the division part of region A and region B has an angle that goes downward as it goes outward from the center in the width direction when viewed from the longitudinal rear surface of the body, that is, it has a square shape. If so, the stretchable base fabric tends to stretch in the direction of muscle contraction, making it difficult to lift the buttocks and to suppress the bulges of the buttocks (see FIG. 7).

Furthermore, by arranging the stretchable base fabric between the areas A to C and other areas, it is possible to satisfy the function of being easy to move. That is, when the regions A to C are continuously covered with the strong tightening material, the tension change when these regions are stretched by the operation becomes very large. On the other hand, when the non-stretch or low stretch sheet is divided and arranged in the areas A to C, when these areas are stretched during operation, the areas A to C are hardly or not stretched at all, and the tension changes due to the stretch. Since only a stretchable base fabric with a small amount of stretch is stretched, ease of movement is ensured.

Also, the part where the skin extends most when the hip joint is bent is the groin. The direction in which the skin of the groin portion extends is downward with an angle of about 15 to 85 degrees as it goes outward from the center in the width direction as viewed from the longitudinal rear surface of the body. In other words, when viewed from the rear in the vertical direction, it has a letter C shape. On the other hand, in the present invention, the shape of the divided part of the region B and the region C is a C-shape when viewed from the longitudinal rear surface. That is, it has an angle that approximates the direction of skin contraction in the groin. For this reason, the room for the stretchable base fabric to be stretched becomes larger than the skin stretched in the groin, and it is easier to move (see FIG. 6). On the other hand, when viewed from the back in the longitudinal direction of the body, if it has an angle that goes upward as it goes outward from the center in the width direction, that is, if it has a reverse C shape, there is room for the stretchable base fabric to stretch Becomes smaller and more difficult to move (see FIG. 7).

FIG. 8A is a front view of a one-piece type swimsuit according to an embodiment of the present invention, and FIG. 8B is a rear view thereof. 8A and 8B, the main part is constituted by the stretchable base fabric (1). Then, a region A (2a, 2b) covering at least the back of the waist with a non-stretch or low stretch material, a region B (3a, 3b) including the bulges of both hips, and the rear surfaces of both thighs Are divided into a region C ′ (5a, 5b) including the inner side of the thigh and a region D (7a, 7b) covering the quadriceps. As a result, the effect of lifting the legs can be further strengthened, and the increase in shape resistance due to abduction of the hip joint by covering the hip adductor muscle group is suppressed, and further, the swelling of the thigh is suppressed. , Water resistance can be lowered. Further, non-stretchable or low stretchable materials are disposed and reinforced on the left and right chest portions 28a and 28b and the abdomen 29. The non-stretchable or low-stretch material of the left and right breasts 28a and 28b can prevent the pectoralis major muscle and the breast from protruding, and can reduce the water resistance. Further, the non-stretchable or low stretchable material of the abdomen 29 increases the internal pressure of the abdomen, so that the waist is not easily bent and can hold a flat stream line.

FIG. 9A is a front view of a one-piece type swimsuit according to another embodiment of the present invention, and FIG. 9B is a rear view thereof. As shown in the rear view of FIG. 9B, a region A (2a, 2b) covering at least the waist rear surface with the non-stretchable or low stretchable material of FIG. 8B, and a region B (3a, 3b) including the bulging portions of both heels And the region C ′ (5a, 5b) including the inner side of the thigh continuously from the rear surface of both thighs and the region D (7a, 7b) covering the quadriceps It is common. The difference is that the area of the region A (2a, 2b) is large, and the central part of the gap between the region B (3a, 3b) and the region C ′ (5a, 5b) is recessed. As in the example of FIGS. 8A-B, the effect of lifting the legs can be further strengthened, and the increase in shape resistance due to the hip joint abduction can be suppressed by covering the hip adductor muscle group, The water resistance can be lowered by suppressing the swelling of the thigh. This swimsuit is opened and closed by opening and closing the fastener 9. As shown in FIG. 9A, non-stretchable or low-stretch materials are disposed and reinforced on the left and right chests 25a and 25b and the abdomen 26a to 26c and 27a to 27c. The non-stretchable or low-stretch material of the left and right breasts 25a and 25b can prevent the pectoralis major muscle and the breast from protruding, and can reduce water resistance. Further, the non-stretchable or low stretchable material of the abdomen 26a to 26c, 27a to 27c increases the internal pressure of the abdomen, so that the waist is not bent easily and a flat stream line can be maintained. Further, a V-shaped or U-shaped non-stretchable or low-stretch material may be disposed on the shin portions 8a to 8b and reinforced. Thereby, bending of a knee can be prevented underwater and a flat stream line can be maintained. Non-stretchable or low stretchable material for the region A (2a, 2b), the region C ′ (5a, 5b), the region D (7a, 7b), the left and right breasts 25a, 25b and the abdominals 26a-26c, 27a-27c Has a 1 mm wide slit that looks like a streak. Thereby, elasticity is expressed, the comfort at the time of wear is improved, and attachment / detachment can also be performed easily.

In FIG. 9B, the shape of the divided part between the region B (3a, 3b) and the region C (5a, 5b) is a C-shaped inner part in the width direction when viewed from the back in the longitudinal direction of the body. Similarly, the outer portion in the width direction has a reverse C shape. As shown in paragraph 0045, since the inverted C-shaped divided portion is difficult to move, a slit is provided in the region C (5a, 5b) in this embodiment to ensure ease of movement.

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