Description

  The present invention relates to a pitching motion assisting wear, and more particularly to a pitching motion assisting wear for assisting a wearer's pitching motion.

  The pitching operation is roughly divided into a wind-up period, a cocking period, an acceleration period, and a follow-through period according to the order of the pitching operations. In the cocking period, when the elbow is slightly above the extended line connecting both shoulders, the maximum range of external rotation is obtained at the shoulder joint. Then, the lower the elbow position from a position slightly above the extension line connecting both shoulders, the smaller the external rotation movable range of the shoulder joint.

  If the transition from the cocking period to the accelerator is performed while the elbow is positioned lower than the extension line connecting both shoulders, the shoulder joint will not be able to obtain a sufficient range of external rotation, so the arm will bend sufficiently. It is not obtained. Therefore, it is difficult to improve the ball speed because a sufficient acceleration period for the ball cannot be obtained. In addition, when the transition from the cocking period to the accelerator is performed in a state where the elbow is at a position lower than the extension line connecting both shoulders, a large valgus stress is applied to the inside of the elbow, so that the elbow joint is burdened. As a result, the elbow may break down. Therefore, in the cocking period, it is desirable that the elbow is slightly above the extended line connecting both shoulders at the top position of the takeback.

  Conventionally, clothing for the purpose of preventing or treating a disorder near the shoulder joint has been proposed. For example, Japanese Patent Laid-Open No. 9-250008 (Patent Document 1) discloses an upper limb protective clothing having a structure in which a portion having a stronger tightening force is arranged in a tape shape on a clothing main body made of a stretchable fabric having an upper body portion. Have been described.

Japanese Patent Laid-Open No. 9-250008

  In the cocking period, it is effective to correct the pitching form so that the elbow is not lowered so that the elbow is slightly above the extension line connecting the shoulders at the top position of the takeback. . However, conventionally, no wear has been proposed that can correct the throwing form so that the position of the elbow is not lowered.

  Note that the upper limb protective clothing described in the above publication reduces the burden on the shoulder joint by a structure in which a portion having a stronger tightening force is arranged in a tape shape on the clothing body, thereby preventing an obstacle near the shoulder joint and the like. The purpose is to promote treatment. Therefore, the upper limb protective clothing described in the above publication does not plan to correct the throwing form so that the position of the elbow is not lowered. Therefore, even if the wearer wears the upper limb protective clothing described in the above publication, it cannot be expected that the throwing form is corrected so that the position of the elbow is not lowered.

  This invention is made | formed in view of the said subject, The objective is to provide the throwing operation | movement assistance wear which can correct a throwing form so that the position of an elbow may not fall.

  The pitching motion assisting wear of the present invention is pitching motion assisting wear for assisting the wearer's pitching motion. This throwing movement assist wear can be worn on the wearer's upper body, and the shoulder line is provided in a downwardly convex manner, and the shoulder line is provided along the shoulder line, and is difficult to stretch from the cloth of the body of the upper garment. A first hardly stretchable member; and a first hardly stretchable member that is provided continuously to the neck portion of the upper garment and extends obliquely with respect to the center line in the width direction of the upper garment; And a second hardly stretchable member that is difficult to stretch from the fabric of the main body.

  The throwing motion assisting wear of the present invention is continuous with an upper garment having a shoulder line projecting downward, a first hardly stretchable member provided along the shoulder line, and the first hardly stretchable member. And a second hardly stretchable member extending obliquely with respect to the center line in the width direction of the upper garment in the vicinity of the neck portion of the upper garment, so that the elbow is lowered below the shoulder line. And the tension | tensile_strength can be provided to a wearer's shoulder and upper arm by the 1st difficult stretch member and the 2nd difficult stretch member. By throwing the wearer so that the tension applied to the shoulder and the upper arm is small, the elbow position can be prevented from being lowered in the pitching operation. In this way, the throwing form can be corrected so that the position of the elbow does not drop.

  As a result, the elbow is positioned above the shoulder line, so that in the cocking period, the elbow is disposed slightly above the extended line connecting both shoulders. Thereby, since the acceleration period with respect to a ball | bowl can fully be obtained, the improvement of a ball speed can be aimed at. In addition, since the hallux stress applied to the elbow can be reduced, the cause of failure can be reduced.

  In addition, the first hardly stretchable member and the second hardly stretchable member apply tension to the shoulder and the upper arm, thereby reducing the tensile load due to the centrifugal force applied to the muscle group at the rear of the shoulder in the follow-through period. be able to. Thereby, failure can be reduced.

  The above-mentioned throwing motion assisting wear is preferably provided at a position away from the second hardly stretchable member with respect to the neck portion of the upper garment, and extends obliquely with respect to the center line in the width direction of the upper garment. And a third hardly stretchable member that is difficult to stretch from the cloth of the main body of the upper garment.

  This pitching movement assisting wearer includes the third hardly stretchable member provided at a position away from the second hardly stretchable member with respect to the neck portion of the upper garment. Further, a strong tension can be applied. Thereby, in the pitching operation, the elbow position can be prevented from further lowering.

  Moreover, since a gap can be provided between the second hardly stretchable member and the third hardly stretchable member, the second hardly stretchable member and the third hardly stretchable member can be stretched by this gap. By being absorbed, easiness of movement can be improved in the pitching operation.

  Preferably, the pitching movement assist wear is provided such that the width of the second hardly stretchable member is larger than the width of the third hardly stretchable member. The second hardly stretchable member is provided continuously with the first hardly stretchable member along the shoulder line, and extends obliquely with respect to the center line in the width direction of the upper garment in the vicinity of the neck portion of the upper garment. Therefore, it is easy to apply a large tension to the wearer's shoulder as compared with the third hardly stretchable member. Since the width of the second hardly stretchable member is set to be larger than the width of the third hardly stretchable member, the tension can be effectively applied to the shoulder of the wearer.

  Further, since the second hardly stretchable member extends obliquely with respect to the center line in the width direction of the upper garment in the vicinity of the neck portion of the upper garment, so as to cover at least a part of the wearer's supraspinatus muscle Is provided. By making the width of the second hardly stretchable member larger than the width of the third hardly stretchable member, the area of the second hardly stretchable member covering the supraspinatus can be increased. The supraspinatus has a heavy burden in throwing motion. The burden on the supraspinatus can be reduced by increasing the area of the second hardly extensible member that covers at least a part of the supraspinatus. Thereby, in the follow-through period, it is possible to further reduce the tensile load due to the centrifugal force around the shoulder, particularly the rear muscle group.

  In the above-mentioned pitching motion assisting wear, the first hardly stretchable member is preferably provided so as to cover the upper side of the sleeve portion of the upper garment. For this reason, since the area in the width direction of the sleeve portion of the first hardly stretchable member can be increased, a larger tension can be applied to the upper arm of the wearer by the first hardly stretchable member.

  In the above-mentioned throwing motion assisting wear, the first hardly stretchable member preferably has a length dimension that is at least half the length dimension of the sleeve of the upper garment. For this reason, since the area of the length direction of the sleeve part of the 1st difficultly stretchable member can be enlarged, the tension | tensile_strength of a wearer can be given much bigger tension | tensile_strength by a 1st difficultly stretchable member.

  As described above, according to the pitching operation assisting wear of the present invention, the pitching form can be corrected so that the position of the elbow is not lowered.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Elements having the same function are denoted by the same reference numerals, and the description thereof will not be repeated unless particularly necessary.

  With reference to FIG. 1 and FIG. 2, the pitching operation | movement assistance wear 1 of one embodiment of this invention is the wear for assisting a wearer's pitching operation | movement. The pitching motion assisting wear 1 is configured to correct the pitching form so that the elbow position does not drop by assisting the wearer's pitching motion. The throwing motion assisting wear 1 mainly includes an upper garment 2 and a hardly stretchable member 3 that is difficult to stretch from the fabric of the main body of the upper garment 2.

  The upper garment 2 is configured to be worn on the upper body of the wearer. The upper garment 2 includes a neck portion 6 that can receive the wearer's neck, a sleeve portion 8 that is positioned on one end 7 side of the neck portion 6 and can receive the wearer's arm, and a neck portion 6 on the one end 7 side. It mainly has a trunk portion 9 that is positioned and can receive the trunk of the wearer. The sleeve portion 8 includes a shoulder portion 4 disposed near the shoulder of the wearer and an upper arm portion 5 disposed near the upper arm of the wearer.

  The torso part 9 has an arm hole 10 provided so that the shoulder and arm of the wearer can pass, and a side part 11 disposed in the vicinity of the wearer. The sleeve portion 8 and the body portion 9 are connected by an arm hole 10. The arm hole 10 is formed obliquely from the neck portion 6 to the side portion 11. The dimension of the outer periphery of the side part 11 of the sleeve part 8 is set to be substantially equal to the dimension of the outer periphery of the connection portion with the shoulder of the upper arm of the wearer. Thereby, an arm can be prevented from dancing in the sleeve part 8. FIG.

  In the shoulder 4 of the upper garment 2, a shoulder line 4a is provided in a convex shape downward. As shown in FIGS. 1 and 2, the shoulder line 4 a is a line formed by the shoulder 4 of the upper garment 2 in a state where the upper garment 2 is spread and placed. Since the shoulder line 4a is convex downward, when the wearer's upper arm falls below the shoulder line 4a, the tension of the hardly stretchable member 3 is applied to the shoulder and upper arm of the wearer. The wearer does not lower the upper arm of the wearer in order to reduce the tension of the hardly stretchable member 3. That is, by providing the shoulder line 4a in a convex shape downward, it is possible to prevent the wearer's upper arm from being lowered. The shoulder line 4 a is provided so as to bend in the direction of the body portion 9 from the neck portion 6 to the upper arm portion 5. The sleeve 8 is provided such that the cuffs extend upward in the length direction of the upper garment 2 in a state where the upper garment 2 is spread and placed.

  Referring to FIG. 3, the pattern paper on the front side of the shoulder portion 4 and the upper arm portion 5 of the throwing motion assisting wear 1 shown as P1 portion in FIG. 1 is formed so that the shoulder line 4a is curved toward the arm hole 10 side. Yes. Referring to FIG. 4, the pattern 4 on the back side of the shoulder portion 4 and the upper arm portion of the throwing motion assisting wear 1 shown as P1 portion in FIG. 2 is also formed so that the shoulder line 4a is curved toward the armhole 10 side. 3 and 4 do not show the seam allowance for the pattern paper. The broken lines in FIGS. 3 and 4 indicate the region where the hardly stretchable member is formed and the sewn portion of the sleeve portion.

  Referring to FIGS. 1 and 2 again, it is preferable that the upper garment 2 is mainly composed of a stretchable fabric so that various operations can be easily performed. Although the upper garment 2 may be configured by one type of stretchable fabric, the upper garment 2 may be configured by combining a plurality of types of stretchable fabric. Moreover, while using a stretchable fabric as a base, a non-stretchable fabric can be used for a part thereof. As the fabric of the main body of the upper garment 2, for example, a knitted fabric or a woven fabric in which fibers selected from polyurethane fibers, polyamide fibers, polyester fibers and the like are combined can be used.

  In the example of FIGS. 1 and 2, the upper garment 2 has a long sleeve shape in which the sleeve portion 8 reaches the vicinity of the wearer's wrist. However, any shape other than the long sleeve type can be adopted as the shape of the upper garment 2. For example, a short-sleeved structure in which the sleeve 8 covers up to the upper arm of the wearer when worn can be employed. Further, a seven-sleeve structure in which the sleeve 8 reaches the vicinity of the center of the wearer's forearm when worn can also be adopted. As described above, the length of the sleeve portion 8 that receives the arm of the wearer in the upper garment 2 can be arbitrarily changed within a range that covers at least a part of the upper arm of the wearer. Moreover, the shape of the neck part 6 and the trunk | drum part 9 of the upper garment 2 can also be selected arbitrarily.

  As described above, the pitching movement assisting wear 1 has the body portion 9, so that the pitching movement assisting wear 1 greatly deviates to the upper side, the lower side, or the like from the original wearing position even when the pitching movement is performed at the time of wearing. Can be suppressed. For this reason, even during the pitching operation, a stable mounting state can be maintained without greatly deviating from the original mounting position.

  The hardly stretchable member 3 includes at least a first hardly stretchable member 3a and a second hardly stretchable member 3b. The first hardly extensible member 3a is provided along the shoulder line 4a. The first hardly extensible member 3a is formed so as to have a width that extends to the front side and the back side along the shoulder line 4a. The first hardly stretchable member 3a is provided so as to be addressed to at least a part of the shoulder and upper arm of the wearer. That is, the first hardly stretchable member 3a is provided on at least a part of the upper garment 2 corresponding to the shoulder and upper arm of the wearer.

  The first hardly stretchable member 3 a is configured to be less likely to stretch than the fabric of the main body of the upper garment 2. At least a part of the first hardly stretchable member 3 a is formed in close contact with the surface of the upper garment 2.

  As shown in FIGS. 1 and 2, the first hardly stretchable member 3 a may be provided so as to cover the upper side of the sleeve portion 8 of the upper garment 2. The first hardly stretchable member 3 a may be provided so as to occupy half or more of the surface area of the sleeve portion 8 of the upper garment 2. Further, the first hardly stretchable member 3 a may have a length dimension that is half or more of the length dimension of the sleeve portion 8 of the upper garment 2. The first hardly stretchable member 3a may be provided such that the width extending from the front side to the back side in the length direction of the sleeve portion 8 of the upper garment 2 changes.

  As shown in FIG. 2, the first hardly stretchable member 3 a may be provided in an area above the side portion 11 of the upper garment 2 so that the area is smaller than an area sandwiching the area. By reducing the area of the first hardly extensible member 3a in the region above the side portion 11, the wearer can easily raise the upper arm during the pitching operation.

  The second hardly extensible member 3b is provided continuously with the first hardly extensible member 3a. The second hardly stretchable member 3b only needs to be provided integrally with the first hardly stretchable member 3a, and the second hardly stretchable member 3b is in complete contact with the first hardly stretchable member 3a. It does not have to be provided. The second hardly stretchable member 3 b is configured to extend in an oblique direction with respect to the center line CL in the width direction of the upper garment 2 in the vicinity of the neck portion 6 of the upper garment 2. Since the second hardly stretchable member 3b is provided in the vicinity of the neck portion 6, the shoulder of the wearer can be firmly held.

  Referring to FIGS. 5 and 6, the second hardly stretchable member 3 b is provided so as to be directed to the upper part of the wearer's scapula 20 and at least a part of the supraspinatus 21. That is, the second hardly stretchable member 3 b is provided in the upper garment 2 at least at a part corresponding to the upper part of the scapula 20 of the wearer and the supraspinatus 21. Since the second hardly extensible member 3b is provided so as to cover the upper part of the scapula 20 and at least a part of the supraspinatus 21, the tension is applied so that the scapula 20 approaches the center of the back. Can do.

  The second hardly stretchable member 3b is configured to be harder to stretch than the cloth of the main body of the upper garment 2. At least a part of the second hardly stretchable member 3 b is formed in close contact with the surface of the upper garment 2.

  Further, as shown in FIG. 2, the hardly stretchable member 3 may have a third hardly stretchable member 3c. The third hardly stretchable member 3 c is provided at a position away from the second hardly stretchable member 3 b with respect to the neck portion 6 of the upper garment 2. A gap 12 may be provided between the second hardly stretchable member 3b and the third hardly stretchable member 3c. The hardly extensible member 3 is not provided in the gap 12. This gap 12 makes it easier to move the wearer's shoulder during the pitching operation. The third hardly extensible member 3 c is configured to extend in an oblique direction with respect to the center line CL in the width direction of the upper garment 2.

  Referring to FIGS. 5 and 6, the third hardly stretchable member 3 c is provided so as to be applied to at least a part of the lower part of the scapula 20, the subspinous muscle 22 and the small circular muscle 23 of the wearer. Yes. That is, the third hardly stretchable member 3 c is provided on at least a part of the upper garment 2 corresponding to the lower part of the wearer's scapula 20, the subspinous muscle 22 and the small circular muscle 23. The third hardly stretchable member 3c is provided so as to cover at least a part of the lower part of the scapula 20, the subspinous muscle 22 and the small circular muscle 23, so that the scapula 20 is brought to the center of the back. Tension can be applied.

  The third hardly stretchable member 3c is configured to be less likely to stretch than the cloth of the main body of the upper garment 2. At least a part of the third hardly stretchable member 3 c is formed in close contact with the surface of the upper garment 2.

  In addition, as shown in FIG. 2, the width of the second hardly stretchable member 3b may be provided to be larger than the width of the third hardly stretchable member 3c. The width of the second hardly stretchable member 3b is a width in a direction intersecting with the direction in which the second hardly stretchable member 3b extends. That is, the width of the second hardly stretchable member 3b in the direction in which the second hardly stretchable member 3b and the third hardly stretchable member 3c are arranged with respect to the neck portion 6. The width of the third hardly extensible member 3c is a width in a direction intersecting with the direction in which the third hardly extensible member 3c extends. That is, the width of the third hardly stretchable member 3c in the direction in which the second hardly stretchable member 3b and the third hardly stretchable member 3c are arranged with respect to the neck portion 6.

  Further, as shown in FIG. 2, the hardly stretchable member 3 may have a fourth hardly stretchable member 3d. The fourth hardly extensible member 3 d is provided on the center line CL in the width direction of the upper garment 2. The fourth hardly extensible member 3d is provided so as to be directed to the center of the wearer's back. In other words, the fourth hardly extensible member 3d is provided in the upper garment 2 at a portion corresponding to the center of the wearer's back.

  Since the fourth hardly stretchable member 3d is provided so as to cover the center of the back of the wearer in the upper garment 2, tension can be applied so that the back muscle of the wearer extends. Therefore, it can suppress that a wearer's spine becomes round. Thereby, a wearer's chest can be stretched. For this reason, a wearer's takeback can be enlarged.

  As shown in FIG. 2, the hardly stretchable member 3 may have a fifth hardly stretchable member 3e. The fifth hardly extensible member 3e is provided to extend in the width direction of the upper garment 2 with a predetermined width. The fifth hardly extensible member 3e is provided so as to be placed below the shoulder blade 20 of the wearer. That is, the fifth hardly stretchable member 3 e is provided in a portion corresponding to the lower part of the shoulder blade 20 of the wearer in the upper garment 2. The fifth difficult-to-extend member 3e tightens the back of the wearer, so that it is possible to suppress a shift such as a rise of the body portion 9 of the throwing motion assisting wear 1.

  As shown in FIGS. 1 and 2, the hardly stretchable member 3 may have a sixth hardly stretchable member 3f. The sixth hardly stretchable member 3f is provided so as to cover the lower side of the sleeve portion 8 with a predetermined width in the vicinity of the distal end portion of the first hardly stretchable member 3a. The sixth hardly extensible member 3f is provided so as to be addressed near the center of the wearer's forearm. That is, the sixth hardly extensible member 3f is provided in the upper garment 2 at a portion corresponding to the vicinity of the elbow joint of the wearer's upper arm. By tightening the wearer's forearm with the sixth hardly extensible member 3f and the first hardly extensible member 3a, the displacement of the sleeve portion 8 of the throwing motion assisting wear 1 can be suppressed.

  The fourth hardly stretchable member 3d to the sixth hardly stretchable member 3f are configured so as not to easily stretch from the fabric of the main body of the upper garment 2, respectively. At least a part of the fourth hardly stretchable member 3d to the sixth hardly stretchable member 3f is formed in close contact with the surface of the upper garment 2.

  The hardly stretchable member 3 is continuously provided in addition to the first hardly stretchable member 3a and the second hardly stretchable member 3b. The hardly stretchable members 3 may be provided integrally with each other, and may not be provided in complete contact with each other.

  The hardly stretchable member 3 can be made of an elastic resin material such as urethane resin. Rubber, silicon, PVC (polyvinyl chloride), polyamide elastomer, polyester elastomer, rubber elastomer, olefin elastomer, polyethylene, polypropylene, nylon, EVA (ethylene-vinyl acetate copolymer), ABS (acrylonitrile-butadiene-) A resin material such as a styrene copolymer) can also be used as each material of the hardly stretchable member 3.

  As shown in FIGS. 1 and 2, the hardly extensible member 3 may be formed in a linear pattern having an arbitrary shape. The linear pattern may be formed by combining a plurality of linear portions. The hardly stretchable member 3 may be formed in a honeycomb shape, for example. Further, the hardly extensible member 3 may be formed in a planar pattern having an arbitrary shape. Further, the hardly stretchable member 3 may be formed by combining a planar pattern and a linear pattern having an arbitrary shape.

  The material, shape, and the like of the hardly stretchable member 3 can be arbitrarily selected. Each of the first hardly stretchable member 3a to the sixth hardly stretchable member 3f may be made of the same material, or at least one of them may be made of a different material. In addition, each of the first hardly extensible member 3a to the sixth hardly extensible member 3f may be configured in the same shape, or at least one of them may be configured in a different shape.

  Next, with reference to FIG. 7, an example of the structure of a linear pattern constituting the above-described hardly stretchable member 3 will be described. FIG. 7 shows a cross-sectional shape of one linear portion constituting the linear pattern.

  In the example shown in FIG. 7, the cross-sectional shape of the linear pattern 31 is substantially rectangular. More specifically, the linear pattern 31 has a side surface 32 that rises substantially perpendicularly from the surface of the upper garment 2 and has a shape such that the upper end corner 33 is pointed. As shown by a dotted line in FIG. 7, the upper end corner portion 33 of the linear pattern 31 may be rounded.

  The force required to stretch the linear pattern 31 is a force corresponding to the tension by the linear pattern 31, but the force is proportional to the volume of the linear pattern 31. Here, as described above, the linear pattern 31 has the side surface 32 that rises substantially perpendicularly from the surface of the upper garment 2, so that the formation area of the linear pattern 31 on the upper garment 2 can be kept small, and the linear pattern 31 is sufficient. A large volume can be secured. That is, it is possible to obtain a desired tension by the linear pattern 31 while keeping the formation area of the linear pattern 31 small.

  Although the height (thickness) and width of the linear pattern 31 can be adjusted arbitrarily, the volume of the linear pattern 31 can be adjusted by adjusting these appropriately, and the tension by the linear pattern 31 can be adjusted. Can be adjusted.

  For example, although it may be required to change the tension of each part by the hardly stretchable member 3 due to differences in the wearer's physique, preferences, etc., the hardly stretchable member 3 is configured as described above. By appropriately adjusting the height (thickness), width, density, etc. of the linear pattern 31, the tension of each part of the hardly stretchable member 3 can be easily changed. Can do.

  Next, with reference to FIG. 8, an example of a method for manufacturing the throwing motion assisting wear 1 according to the embodiment of the present invention will be described.

  As shown in FIG. 8, first, a resin for forming the hardly stretchable member 3 is prepared (S10). For example, a urethane resin having predetermined elasticity and considered to have good moldability is prepared.

  Next, the resin is introduced into a mold (S20). This mold has a recess (cavity) corresponding to the shape of the hardly extensible member 3 and introduces resin into this recess. In introducing the resin into the mold, for example, the resin may be introduced into the mold in a flowable state (for example, liquid). Thereafter, the resin is heated in the mold (S30). For example, heating is performed at a temperature equal to or higher than the curing temperature of the resin. As a result, a part of the resin (part in contact with the mold and its vicinity) is cured or the entire resin is in a semi-cured state.

  Next, the resin in the above-described state is brought into close contact with a fabric for producing the upper garment 2 (for example, a stretchable fabric) (S40). Specifically, the cloth is placed on a resin material that is heated in a mold, and pressure is applied to the cloth to bring the cloth into contact with the resin. By curing the resin in this state, the desired hardly extensible member 3 can be formed on the surface of the fabric. In addition, after forming the hardly stretchable member 3 using a metal mold | die, it is also possible to adhere | attach and form this hardly stretchable member 3 on cloth | dough using an adhesive agent.

  By forming the hardly extensible member 3 on the surface of the fabric using the mold as described above, for example, a linear pattern 31 in which the side surface 32 extends in a direction substantially perpendicular to the surface of the fabric as shown in FIG. Can be formed.

  After forming the hardly stretchable member 3 on the surface of the fabric as described above, the pitching operation assisting wear 1 as shown in FIGS. 1 and 2 can be produced by sewing the fabrics together.

  Next, the effect of the pitching operation assisting wear according to the embodiment of the present invention will be described in comparison with a comparative example.

  Referring to FIG. 6, in the pitching operation, the supraspinatus 21, the subspinous muscle 22 and the small circular muscle 23 at the rear of the scapula 20 and the subscapular muscle at the front of the scapula 20 (referred to as a rotator cuff). (Not shown) has an important function. In order to prevent the elbow position from being lowered during the pitching operation, in particular, the supraspinous muscle 21, the subspinous muscle 22 and the small circular muscle 23 at the rear of the scapula 20 functioning to raise the upper arm by bending the chest. is important.

  According to the throwing motion assisting wear 1 of the embodiment of the present invention, when the elbow is lowered below the shoulder line 4a, the shoulder of the wearer is caused by the first hardly stretchable member 3a and the second hardly stretchable member 3b. And tension can be applied to the upper arm. At this time, as shown in FIG. 5, tension can be applied to the upper arm in the direction D1 mainly by the first hardly stretchable member 3a. Also, tension can be applied to the rear part of the scapula 20 in the direction D2 mainly by the second hardly stretchable member 3b. By throwing the wearer so that the tension applied to the shoulder and the upper arm is small, the elbow position can be prevented from being lowered in the pitching operation.

  On the other hand, referring to FIG. 9 and FIG. 10, the wear 100 of the comparative example is normal wear. The upper garment 2 of the wear 100 of the comparative example is made of stretchable fabric. The wear 100 of the comparative example is not provided with the hardly extensible member 3 shown in FIG. Therefore, in the wear 100 of the comparative example, no tension is applied by the hardly stretchable member 3 according to the position of the elbow.

  With reference to FIG. 11 and FIG. 12, the pitching movement assisting wear 1 according to the embodiment of the present invention and the wear 100 of the comparative example will be described in comparison. In FIG. 11 and FIG. 12, in order to make it easier to see the angle of the upper arm of the wearer, the pitching movement assisting wear 1 is not shown in FIG. 11, and the wear 100 of the comparative example is not shown in FIG.

  As shown in FIG. 11, the pitching movement assisting wear 1 of the present invention can prevent the position of the elbow from being lowered during the pitching movement. On the other hand, as shown in FIG. 12, since the wear 100 of the comparative example is not provided with the hardly stretchable member 3, tension is applied to the shoulder and upper arm of the wearer so that the position of the elbow is not lowered during the pitching operation. Never happen.

  That is, the pitching movement assisting wear 1 according to the embodiment of the present invention can increase the position of the wearer's elbow compared to the wear 100 of the comparative example, and the preferred elbow position in pitching operation, that is, pitching The operation assisting wear 1 can be guided upward from an extension line connecting both shoulders of the wearer. Θ1 and θ2 indicate the angle between the line connecting the shoulders of the wearer and the upper arm in order to make the position of the elbow easier to understand.

  The pitching movement assisting wear 1 according to the embodiment of the present invention can prevent the elbow position from being lowered in the pitching operation as described above, and therefore corrects the pitching form so that the elbow position does not drop. Can do.

  According to the pitching movement assisting wear 1 of the embodiment of the present invention, the elbow is positioned above the shoulder line 4a by correcting the pitching form so that the position of the elbow is not lowered. The elbow is arranged slightly above the extended line connecting the shoulders. Thereby, since the acceleration period with respect to the ball is sufficiently obtained, the ball speed can be improved. In addition, since the hallux stress applied to the elbow can be reduced, the cause of failure can be reduced.

  Further, when the first hardly stretchable member 3a and the second hardly stretchable member 3b apply tension to the shoulder and the upper arm, in the follow-through period, the tensile load due to the centrifugal force applied to the muscle group at the rear of the shoulder is reduced. It can be reduced. Thereby, failure can be reduced.

  The pitching movement assisting wear 1 according to the embodiment of the present invention includes a third hardly stretchable member 3c provided at a position away from the second hardly stretchable member 3b with respect to the neck portion 6 of the upper garment 2. It is preferable. In this case, a stronger tension can be applied by the third hardly stretchable member 3c. Thereby, in the pitching operation, the elbow position can be prevented from further lowering.

  Further, since the gap 12 can be provided between the second hardly stretchable member 3b and the third hardly stretchable member 3c, the second hardly stretchable member 3b and the third hardly stretchable member can be formed by the gap 12. The ease of movement in the pitching operation can be improved by absorbing the extension of the sex member 3c.

  In the pitching operation assisting wear 1 according to the embodiment of the present invention, it is preferable that the second hardly stretchable member 3b is provided to have a width larger than that of the third hardly stretchable member 3c. The second hardly stretchable member 3b is provided continuously with the first hardly stretchable member 3a along the shoulder line 4a, and near the center line CL in the width direction of the upper garment 2 in the vicinity of the neck portion 6 of the upper garment 2. Therefore, it is easy to apply a larger tension to the shoulder of the wearer than the third hardly stretchable member 3c. Since the width of the second hardly stretchable member 3b is set to be larger than the width of the third hardly stretchable member 3c, it is possible to effectively apply tension to the shoulder of the wearer.

  Further, since the second hardly stretchable member 3b extends obliquely with respect to the center line CL in the width direction of the upper garment 2 in the vicinity of the neck portion 6 of the upper garment 2, at least of the supraspinatus muscle 21 of the wearer. It is provided so as to cover a part. By making the width of the second hardly stretchable member 3b larger than the width of the third hardly stretchable member 3c, the area of the second hardly stretchable member 3b covering the supraspinatus 21 can be increased. The supraspinatus 21 has a heavy load in the pitching operation. By increasing the area of the second hardly extensible member 3b covering at least a part of the supraspinatus 21, the burden on the supraspinatus 21 can be reduced. Thereby, in the follow-through period, it is possible to further reduce the tensile load due to the centrifugal force around the shoulder, particularly the rear muscle group.

  In the pitching motion assisting wear 1 according to the embodiment of the present invention, the first hardly stretchable member 3a is preferably provided so as to cover the upper side of the sleeve portion 8 of the upper garment 2. For this reason, since the area in the width direction of the sleeve portion 8 of the first hardly stretchable member 3a can be increased, it is possible to apply even greater tension to the upper arm of the wearer by the first hardly stretchable member 3a. it can.

  In the throwing motion assisting wear 1 according to the embodiment of the present invention, the first hardly stretchable member 3a preferably has a length dimension that is at least half the length dimension of the sleeve portion 8 of the upper garment 2. . For this reason, since the area in the length direction of the sleeve portion 8 of the first hardly stretchable member 3a can be increased, a larger tension is applied to the upper arm of the wearer by the first hardly stretchable member 3a. Can do.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

  The present invention can be applied particularly advantageously to a pitching motion assisting wear for assisting a wearer's pitching motion.

  1 throwing movement assist wear, 2 upper garments, 3 hardly stretchable members, 3a to 3f 1st hardly stretchable members to 6 hardly stretchable members, 4 shoulder portions, 4a shoulder lines, 5 upper arm portions, 6 neck portions, 7 One end, 8 Sleeve, 9 Body, 10 Armhole, 11 Side, 12 Gap, 20 Scapula, 21 Supraspinous muscle, 22 Subspinous muscle, 23 Small circular muscle, 31 Linear pattern, 32 Side, 33 Top corner, 100 wear.
