Description

[Technical field]

[0001] The present invention relates to an upper garment for sports involving arm swings. [Background technology]

[0002] For example, the upper garment disclosed in Patent Document 1 is intended to facilitate smooth movement. Specifically, the top of Patent Document 1 has a body part and sleeve parts. The sleeve parts are made of set-in front sleeves and lug-in back sleeves, and are designed to protrude diagonally downward in front of the front body part from the beginning. In addition, the sewing position (sleeve attachment line) where the body part and sleeve parts are sewn together is located inside the acromion of both shoulders when viewed in the forehead axis direction (the axis in the left-right direction of the human body), so that stress is not applied to the shoulder joints by the sewing parts of the sleeve parts and the body part, and the movement around the shoulders is prevented from being hindered. In this way, the top of Patent Document 1 makes it easy to perform the basic posture of putting both arms out diagonally downward in front of the body in a forward leaning posture, and also makes it possible to smoothly transition from this basic posture to the next movement. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5658716 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the jacket in Patent Document 1 has both set-in and lug-in sleeves, resulting in many sewn areas with poor elasticity, which hinders arm movement and makes production difficult. In addition, in sports that involve swinging, such as table tennis, badminton, and tennis, the arms and shoulders move in conjunction with the movement of the torso, so simply improving arm and shoulder movement, as in the jacket in Patent Document 1, is not sufficient.

[0005] The present invention has been made to solve the above problems, and has an object to provide a sports upper garment that allows ease of movement even in swing sports and that is easy to manufacture. [Means for solving the problem]

[0006] The above problem is solved by a sports top which comprises a body part which is stretchable overall and which consists of a front body part and a back body part, and a set-in sleeve part which is a tubular part formed from a single piece of fabric, one open end of which, which is a cuff, is located closer to the shoulder than the elbow, and the other open end of which is sewn to the body part, and which has a sleeve attachment line which is the sewn part between the body part and the sleeve part, is closer to the neck than the shoulder joint when worn, and the back body part is formed larger in horizontal dimension than the front body part, so that when worn, the sewing line between the back body part and the front body part around the flank is located forward of the center of the sagittal axis direction of the flank, and the sleeve part has a sewing line around the underarm of the front sleeve and the rear sleeve, and when worn, the sewing line around the underarm is located forward of the center of the sagittal axis direction of the underarm, and the front cuff is curved so as to be convex toward the sleeve attachment line.

[0007] According to the above configuration, the sports jacket comprises a body part consisting of a front body and a back body, and a sleeve part which is a tubular part made of a single piece of fabric and has an open end opposite to the cuffs sewn to the body part with a set-in specification. Therefore, the pattern can be made with only the front body, the back body, and a pair of sleeves (each of the pair is made of a single piece of fabric), making it easy to manufacture. Furthermore, since the sleeve attachment line, where the body part and the sleeve part are sewn together, is located closer to the neck than the shoulder joint, the less elastic sewn part between the body part and the sleeve part does not hinder movement of the shoulder joint, thereby improving the range of motion of the shoulder. Moreover, by forming the back body larger than the front body in terms of horizontal dimension, when worn, the seam between the back body and the front body around the flank is located forward of the center of the sagittal axis direction of the flank (front-to-back direction of the wearer). This allows the back body to be patterned according to the amount of movement on the back side when twisting the torso and swinging back and forth in table tennis, for example, and there is no seam line with poor elasticity. This allows the torso to move easily when swinging, and the shoulders and arms to move smoothly accordingly. In addition, the sleeve portion has a sewing line around the underarm of the front sleeve and the back sleeve, and when worn, the sewing line around the underarm is forward of the center of the sagittal axis direction of the underarm. Therefore, the back sleeve can be patterned according to the amount of movement from pulling the arm to hitting the ball, and there is no sewing line with poor elasticity. Therefore, the arm movement during the swing is improved. In addition, the front cuffs are curved so that they are convex toward the sleeve attachment line, which prevents the arm from getting caught in the cuffs when swinging from back to front.

[0008] Also, preferably, the upper end of the sleeve is inclined upward with respect to an imaginary extension of the shoulder line, so that the apex of the sleeve is already angled upward, allowing the player to easily raise their arm when smashing or the like.

[0009] In addition, preferably, the body portion has higher elasticity in the horizontal direction than in the vertical direction, while the sleeve portion has higher elasticity in a direction perpendicular to the sleeve length direction than in the sleeve length direction, and the sewing line around the side and the sewing line around the underarm are connected. In this way, the body portion has a relatively high degree of elasticity in the horizontal direction, which facilitates twisting motion of the body when swinging. In addition, the sleeves have a relatively high degree of elasticity in the direction perpendicular to the sleeve length (i.e., in the direction approximately parallel to the sleeve width), making it easy to raise your arms. Moreover, since the sewing line around the armpit area and the sewing line around the underarm area are connected at the front, the only sewing line with poor elasticity from the cuff through the underarm and underarm area to the armpit area is the sleeve attachment line, allowing the fabric to fully elasticate, making it easier to raise your arms. Effect of the Invention

[0010] As described above, according to the present invention, it is possible to provide a sports upper garment that allows ease of movement even in swing sports and is easy to manufacture. [Brief description of the drawings]

[0012] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In addition, since the embodiments described below are preferred specific examples of the present invention, various technically preferable limitations are attached, but the scope of the present invention is not limited to these aspects unless otherwise specified in the following description to the effect that the present invention is limited. In addition, in each drawing, similar components are given the same reference numerals and detailed descriptions are omitted as appropriate.

[0013] [Overview of sportswear] First, an overview of a sports top (hereinafter, referred to as "top") 10 will be described with reference to Figs. 1 to 3. The jacket 10 shown in Figures 1 to 3 is suitable for sports, particularly sports such as table tennis, badminton, and tennis in which the arms are swung back and forth or smashed by raising and lowering the arms, and has a body part 20 and a pair of sleeve parts 30, 30. The bodice 20 and the pair of sleeves 30, 30 are preferably made of a generally stretchable fabric, such as a known polyester that is stretchable and can quickly dry sweat. However, the present invention is not limited to polyester. In this embodiment, as shown in the two enlarged views enclosed by the dashed and dotted lines in Fig. 1, the fabric is provided with numerous holes HL to provide high stretchability and sweat release.

[0014] The body portion 20 is made up of a front body portion 22 that covers the chest and abdomen, and a back body portion 24 that covers the back. The front body portion 22 and the back body portion 24 are each made from a single piece of fabric, and the front body portion 22 is not divided into an upper front body portion and a lower front body portion, for example. The hem 24a of the back body 24 is a round cut that convex downward, while the hem 22a of the front body 22 is curved to convex upward (towards the neck). This prevents the hem 22a of the front body 22 from getting in the way of a forward-leaning posture in which the upper body is bent slightly forward, and also prevents the back from being exposed. Although not present in the body part 20 of this embodiment, slits may be formed on both sides and pockets may be provided. Also, the neckline 20a of this embodiment is a round neck, but it may also be a V-neck or slit neck.

[0015] Since the pair of sleeves 30, 30 have the same configuration, unless otherwise specified, the following will only describe one of the sleeves 30. The sleeves 30 are short sleeves with cuffs 35 located closer to the shoulder than the elbow, which gives the top 10 roughly the same external shape as a T-shirt. The sleeve portion 30 is formed by rolling a single piece of fabric into a tubular portion, one open end of which is a cuff 35, and the other open end 34 is set-in and sewn to the body portion 20. That is, the reference numeral 34 shown in Figures 1 and 2 is the sleeve attachment line, which is the sewn part between the body portion 20 and the sleeve portion 30.

[0016] [Features of the sleeves and surrounding area] The outline of the upper garment 10 of this embodiment has been described above, but the sleeve portions 30 and the surrounding areas have further features, which will be described below with reference to Figs. 1 to 4. First, as shown in Figures 1 and 2, the sleeve attachment line 34, which is the sewn part between the body part 20 and the sleeve part 30, is located closer to the neck than the shoulder joint (the joint between the humeral head and the glenoid cavity, i.e., the glenohumeral joint) SJ. That is, the sleeve attachment line 34 of each of the pair of sleeve parts 30, 30 is located closer to the center of the forehead axis direction (left and right direction of the wearer) X than the shoulder joint SJ. As shown in Figure 4, such a sleeve attachment line 34 can be obtained by making the shoulder width SW smaller than before so that the sleeve attachment line (sleeve opening) 34 is closer to the collar opening 20a than before, and sewing the sleeve cap 310 there.

[0017] As for the sleeve 30, a single piece of fabric 300 for the sleeve shown in FIG. 4 is formed into a tubular shape, and when this tubular shape is sewn to the body part 20, as shown in FIGS. 1 to 3, the sewing line L1 around the underarm of the front sleeve 38 and the back sleeve 39 is set to be on the front side. In other words, there is only one sewing line L1, which is a sewing part for making the sleeve 30 into a tubular shape with a single piece of fabric, and this sewing line L1 is arranged on the front side (front side) of the center part OP1 in the sagittal axis direction of the underarm. How far forward the sewing line L1 should be can be determined based on the size of the back sleeve 39 determined according to the swing width of the upper arm in the front and rear directions. Although the sewing line L1 shown in FIG. 1 is substantially straight, it may be curved.

[0018] As shown in FIG. 1, the front cuff 35a is curved so as to be convex toward the sleeve attachment line 34. In this embodiment, the length W1 of the front cuff 35a in FIG. 1 in the direction extending from the center of the cuff width to the sleeve attachment line 34 is shorter than the length W2 of the rear cuff 35b in FIG. 2 in the direction extending from the center of the cuff width to the sleeve attachment line 34, and only the front cuff 35a is curved. This curvature can be achieved by forming a curved portion 320 toward the collar 20a in the portion corresponding to the front cuff 35a as shown in FIG. 4. The rear cuff 35b may also be curved so as to be convex toward the sleeve attachment line 34.

[0019] In addition, the upper end 30a of the sleeve 30 shown in Fig. 1 and Fig. 2 is arranged with an upward inclination angle θ1 with respect to the imaginary extension line ML of the shoulder line, and is patterned from the beginning for lifting the arm. And, even if the inclination angle θ1 is large, the size of the armhole is made large and some room is provided around the armpit AR so that there is no feeling of tightness when the arm is lowered. The inclination angle θ1 in this embodiment is about 4 to 6 degrees. Such an inclination angle θ1 can be achieved by lowering the sleeve cap 310 shown in Fig. 4 compared to the conventional one.

[0020] [Characteristics of the best viewing area] Next, the features of the main viewing portion 20 of this embodiment will be described with reference to Figs. Regarding the horizontal dimension (the forehead axis direction in the development views of Figs. 4 and 5), the dimension X1 of the back body 24 shown in Fig. 5 is made larger than the dimension X2 of the front body 22 shown in Figs. 1 and 4. In other words, in sports such as table tennis where the torso is twisted to some extent and the arms are swung back and forth, the back body 24 is made larger in accordance with the amount of movement of the back accompanying the twisting of the torso. As a result, when worn, as shown in Figs. 1 and 3, the seam line L2 between the back body 24 and the front body 22 around the flank (hereinafter referred to as the "flank seam line") does not exist in the center in the sagittal axis direction of the flank (the line VL in Fig. 3), but is located further forward. This side seam line L2 is connected to the seam line L1 around the underarm, and the seam line L1 around the underarm extends directly to the front periphery of the flank.

[0021] [Stretchability characteristics] Next, the stretchability characteristics of the top 10 will be described with reference to FIG. As described above, the upper garment 10 is stretchable overall, but the stretchability differs depending on the direction. That is, when worn, the bodice section 20 has higher stretchability in the horizontal direction X than in the vertical direction (length direction) Z in FIG. 1. Specifically, as shown in the diagram surrounded by the two-dot chain line in FIG. 1, countless holes HL are formed in the fabric of the bodice section 20. The holes HL include relatively large holes HL1 and small holes HL2. The large holes HL1 are arranged vertically and horizontally in a checkerboard pattern, but the small holes HL2 are arranged only along the horizontal direction X, between the multiple large holes HL1. The fibers are dense in the areas without holes HL. In contrast, the sleeve portion 30 has higher stretchability in the direction perpendicular to the sleeve length direction (the direction approximately W1 in the figure) Z than in the sleeve length direction. This high stretchability can be achieved by rotating the fabric of the back portion 20 approximately 90 degrees, and more specifically, as shown in the diagram enclosed by the dashed line in Figure 1, by arranging small holes HL2 only along the direction Z perpendicular to the sleeve length direction between multiple large holes HL1 arranged in a grid pattern. The difference in elasticity may be realized, for example, by changing the amount of fiber depending on the direction. In the present embodiment, the difference in elasticity depending on the direction is slight and not large, but it may be large depending on the type of sport.

[0022] This embodiment is configured as described above. For example, in the table tennis example shown in FIG. 6, the sleeve attachment line 34 is located closer to the neck than the shoulder joint SJ, so that the shoulder joint SJ and the muscles and tendons around it do not come into contact with the sleeve attachment line 34, which has low elasticity, and interfere with the swing, even when the arm is swung back and forth. The sewing line L1 around the underarm is located on the front side, and the rear sleeve 39 (see FIG. 3) is patterned according to the amount of movement from pulling the arm to hitting the ball, so that the arm can move smoothly when hitting the ball. The front cuff 35a is curved so as to be convex toward the sleeve attachment line 34, so that the arm is prevented from getting caught when swinging from the back to the front, and the accuracy of ball control can be improved. The sleeve 30 is also patterned with an upward inclination angle θ1 (see FIG. 1) for raising the arm from the beginning, so that the stress when raising the arm is reduced as shown in FIG. 7, and the accuracy of smashes, etc. can be improved.

[0023] Furthermore, while the above-mentioned improvement in movement is mainly due to the characteristics of the sleeve portion 30 and its surroundings, it is preferable that the arms move in conjunction with the movement of the torso (in other words, hand-beating is not preferable), and in this embodiment, the back body 24 is patterned large in accordance with the amount of movement of the back accompanying the twisting of the torso, and since there are no sewing lines with poor elasticity there, and the side sewing lines L2 are on the front side, the twisting movement of the torso (movement in the RT direction in FIG. 6) can be easily performed. Furthermore, due to the relatively high elasticity of the body portion 20 in the horizontal direction X, this twisting movement of the torso can be performed even more easily. Therefore, the arms and shoulders can move smoothly in accordance with the easy movement of the torso during the swing.

[0024] Moreover, since the side seam line L2 and the seam line L1 around the underarm are connected at the front, as shown in Fig. 7, the only seam line with poor elasticity from the cuff 35 through the underarm and underarm to the side is the sleeve attachment line 34. Therefore, when the arm is raised far back and upwards for a smash, the elasticity of the fabric is fully exhibited. Moreover, since the sleeve portion 30 has a relatively high elasticity in the direction Z perpendicular to the sleeve length direction, it becomes easy to start the movement of raising the arm. Therefore, smashes and the like can be easily performed.

[0025] Thus, it is possible to provide a top 10 that is ideal for sports in which the arms are swung back and forth or smashed by raising and lowering the arms, such as table tennis, badminton, tennis, etc. Moreover, this top 10 can be easily manufactured using only the front body 22 and back body 24, each made from a single piece of fabric, and the pair of sleeves 30, 30, each made from a single piece of fabric.
