Description

  The present invention relates to a shirt worn while being in close contact with the surface of the upper body of the wearer, and more particularly to a shirt suitable for sports using a racket.

  In recent years, sports that use rackets such as tennis, badminton, squash, and table tennis are prosperous even in cold weather such as winter. Long sleeve shirts are required during such cold seasons. In addition, some players wear long-sleeved shirts to prevent sunburn even in warm weather. In sports using rackets, the human body moves in various directions.

  Taking tennis as an example, in a normal hit ball (rally), the back is greatly deformed in the lateral direction, and the arm moves in an arc mainly in the horizontal direction together with the racket. In a serve or smash, the abdomen extends in the vertical direction, and the arm moves in a circular arc from the vertical to the diagonal direction together with the racket. Traditionally, shirts that match the movement of the human body have not been developed.

The present applicant has already proposed a baseball underwear in which a plurality of types of fabrics having different tightening forces are arranged (Patent Document 1). As another proposal, a shirt in which a unidirectional stretch fabric is arranged in a specific direction has been proposed (Patent Document 2). However, these shirts are still unsatisfactory and have a problem that they do not follow the ball striking motion of the racket, and suitable wear is still required from the market.
Japanese Patent No. 3872036 JP 2001-254212 A

  In order to solve the above-described conventional problems, the present invention provides a shirt that follows a ball striking motion of a racket and that does not hinder the movement of the human body despite being in close contact with the skin.

The shirt of the present invention is a shirt worn in a state of being in close contact with the surface of the wearer's upper body,
Stretch material that is relatively high compared to the direction in which one direction is perpendicular, the upper part of the back body extends sideways, the lower part extends vertically, the front body extends vertically, the upper arm to shoulder Is arranged in the direction extending horizontally, the side and elbow parts extending in the vertical direction, and the sleeve part extending in the direction extending horizontally.

  The present invention provides a striking ball for a racket in spite of being in close contact with the skin by arranging a stretch material having a relatively high elongation in a direction where the unidirectional elongation is perpendicular to a portion where the movement of the human body is large. A shirt that follows the movement and does not obstruct the movement of the human body can be provided. Further, the stretch fabric may be used so that only the directionality is different. In this case, the design is simple and the shirt can be provided at a low cost.

The inventors mainly focused on the tennis player and analyzed the movement of the body in the hitting motion. As a result, the following was found.
(1) In a normal rally, the upper back including the vicinity of both shoulder blades has a large horizontal movement (direction perpendicular to the height direction).
(2) In the posture of receiving a serve or picking up a ball, the movement from the vicinity of the lumbar spine to the lower back is large in the vertical direction (height direction).
(3) When serving and smashing, movement from the chest to the abdomen is large in the vertical direction (height direction).
(4) In a general hitting motion, the movement in the horizontal direction (direction perpendicular to the height direction) is large in the vicinity of the deltoid and biceps.
(5) The movement in the vertical direction (height direction) is large near the armpit and the elbow.
(6) The movement in the horizontal direction (direction perpendicular to the height direction) is large near the wrist.

  Based on the above analysis, several materials were selected and designed. As a result, in a shirt that is composed of a stretch material and is worn in close contact with the surface of the upper body of the wearer, the stretch material is relatively high compared to the direction in which the elongation in one direction is orthogonal. It turned out that a good thing is obtained if it creates. Here, the main component refers to a portion that substantially covers the skin. Materials such as collars, cuffs, hems, and pockets as required may be arbitrary.

  More specifically, the main components are arranged such that the upper part (about 2/3) of the back body extends in the horizontal direction and the lower part (about 1/3) extends in the vertical direction. At that time, it is preferable that the back part is sewn in an upward arc shape from the side of the pelvis to the spine. This is to adjust the direction of extension according to the movement of the human body.

  Stretch material is placed in the longitudinal direction in the front body. When serving and smashing, the movement from the chest to the abdomen is large in the vertical direction (height direction). At this time, the shoulder portion is preferably sewn with the back body in the vicinity of the clavicle. This is because the upper part of the shoulder has a large lateral movement. Further, it is preferable to sew so that the sewing portion does not enter the armpit. This is because if there is a sewing part under the armpit and the shirt gets wet due to sweating, the skin may hurt due to friction with the sewing part if the arm is moved repeatedly.

  Stretch material is placed in the direction that the shoulder extends from the upper arm to the side. This is because the movement in the horizontal direction (direction perpendicular to the height direction) is large in the vicinity of the deltoid and biceps. Stretch material is arranged in the direction that the side part and the elbow part extend vertically. This is because the movement in the vertical direction (height direction) is large in the vicinity of the armpits and elbow heads. Stretch material should be placed in the direction of the sleeves. This is because the vicinity of the wrist has a large movement in the horizontal direction (direction orthogonal to the height direction).

  The stretch material is preferably 1.2 to 4 times higher than the direction in which the elongation in one direction is orthogonal. If it is this range, it will become more comfortable to follow the movement of the human body.

  The stretch material preferably has an elongation in one direction of 150% or more and 500% or less in a load range of 0 to 20 N and a width of 5 cm, and an elongation in an orthogonal direction of more than 100% and less than 150%. If it is this range, it will become more comfortable to follow the movement of the human body without obstructing the movement of the human body. In particular, if the elongation in one direction is 150% or more and 500% or less, there is moderate muscle tightening, it follows the elongation of the skin, it is hard to feel a crispness, it is easy to put on and take off, the cloth is difficult to see through, and the strength is high There are advantages.

  The stretch material may be one-way or two-way knitted or woven. As the woven fabric, plain weave, oblique weave, satin weave, altered plain weave, altered satin 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. The knitting includes round knitting, weft knitting, warp knitting (including tricot knitting and raschel knitting), pile knitting, flat knitting, tengu knitting, rib knitting, smooth knitting (double-sided knitting), rubber knitting, pearl knitting, There are denby tissue, cord tissue, atlas tissue, chain tissue, insertion tissue and the like. Preferably, it is a tricot warp knitted fabric of a half structure. This is because it is thin and comfortable to wear and is suitable for sports wear. The yarns used in these knitted or woven fabrics preferably use a combination of synthetic fibers such as polyester and nylon and elastic fibers such as polyurethane. Synthetic fibers and elastic fibers may be used together, or a covering yarn in which the outer sides of the elastic fibers are covered with synthetic fibers may be used.

The stretch material preferably has a basis weight in the range of 120 to 230 g / m ² , more preferably in the range of 140 to 210 g / m ² , and particularly preferably in the range of 160 to 190 g / m ² . If it is the said range, there exists an advantage which does not impair a motor function, is durable, is hard to see through, is light and is easy to move.

  This will be described below with reference to the drawings. FIG. 1A is a front view of a shirt according to an embodiment of the present invention, and FIG. 1B is a rear view thereof. 1A and 1B, a shirt 10 is mainly composed of a front body 1, an upper part 2 of the back body, a lower part 3, an upper arm to a shoulder part 4, a side part 5, an elbow part 6, and a sleeve part 7. A part is formed. The main component is formed of a stretch material and is worn in a state of being in close contact with the surface of the upper body of the wearer. In order to sew in a state of being in close contact with the surface of the upper body of the wearer, sewing can be performed by following the JASPO standard.

  The shirt 10 uses a stretch material that has a relatively high elongation in one direction as compared to a direction that is orthogonal. For example, as shown in FIGS. 2A to 2B, a stretch material in which the elongation in one direction is 250% and the elongation in the orthogonal direction is 125% can be used in the range of load 0 to 20N and width 5 cm.

  The upper part 2 of the back body extends in the horizontal direction, the lower part 3 extends in the vertical direction, the front body 1 extends in the vertical direction, the shoulder 4 from the upper arm extends in the horizontal direction, the side part 5 and the elbow part 6 The stretch material is placed in the direction extending vertically and the sleeve 7 is sewn in the direction extending horizontally.

  The shirt of the present invention is suitable for sports using rackets such as tennis, badminton, squash, table tennis, etc. It can also be applied to sports performed outdoors in the season. The shirt of the present invention is particularly suitable for racket sports wear. Furthermore, the shirt of this invention is applicable to an undershirt, an inner shirt, or an outer shirt. Among these, it is preferable to apply to an undershirt.

  Hereinafter, it demonstrates more concretely using an Example. In addition, this invention is limited to a following example and is not interpreted.

(Example 1)
A half-trick tricot warp knitted fabric was knitted by using 84 mass% of false twisted yarn 33 dtex (decitex) -36 filament made of polyethylene terephthalate filament and 16 mass% of polyurethane elastic filament 22 dtex. The organization chart of this knitting is shown in FIG. In FIG. 3, F indicates the front and B indicates the back. The basis weight of the obtained knitted fabric was 178 g / m ² .

  As shown in FIGS. 2A and 2B, this knitted fabric was a stretch material in which the elongation in one direction was 250% and the elongation in the orthogonal direction was 125% in the range of load 0 to 20N and width 5 cm. The undershirt shown in FIGS. 1A-B was sewn using this knitted fabric. Sewing was performed according to the JASPO standard so as to be in close contact with the surface of the upper body of the wearer. The undershirt was 136 g in L size.

  The undershirt obtained was tested by five male tennis players. The comparison was made in the same manner as in Example 1, except that the knitted fabric of Example 1 was sewn along the height direction (the arm was in the length direction). As a result, the sensory evaluation shown in the following Table 1 was obtained.

(Remarks) Evaluation score 5: Clearly better than the comparison product.
4: Better than the comparison product.
3: Equivalent to comparative product.
2: Slightly inferior to the comparative product.
1: Clearly inferior to the comparative product.

  From the above results, it was confirmed that the shirt of this example followed the movement of tennis play, did not inhibit the movement of the human body, and had a good wearing feeling.
