Description

Wearing articles covering the elbow

The present invention relates to a wearing article that covers an elbow.

The importance of swinging arms is known for sports such as running, walking, and golf. For example, in running, by pulling the elbow backward, the pelvis rotates and leads to a forward driving force.

¡If you swing your arms with your armpits open and your elbows away from your body, you will swing your arms in the left-right direction. On the other hand, by swinging the arm with the side closed, the arm is swung in the front-rear direction, the forward propulsive force is increased, and the arm can be swung efficiently.

Therefore, there are wearing articles such as undershirts and supporters that achieve efficient arm swing by guiding the external rotation of the shoulder joint (see, for example, Patent Document 1 and Patent Document 2). The undershirt described in Patent Literature 1 is cut in a spiral shape from the vicinity of the neck portion to the vicinity of the elbow portion through the shoulder portion. It is wound up diagonally downward. Further, in the forearm of the undershirt described in Patent Document 1, the cut piece is rolled while rotating around several times.

The supporter described in Patent Document 2 has a support portion that surrounds the elbow head in order to prevent excessive internal rotation and valgus. The support portion is arranged near the center of the upper arm and is connected to an anchor portion that tightens the limb.

However, all worn articles are considered problematic in terms of ease of movement.

In the undershirt described in Patent Document 1, since the cutting piece provided between the vicinity of the neck portion and the vicinity of the elbow portion through the shoulder portion has a strong elongation, movement around the shoulder joint may be hindered. . Further, in the forearm of the undershirt described in Patent Document 1, the cutting piece is rolled while rotating around several times, so that there is a possibility that the movement of the wrist is restricted.

In the supporter described in Patent Document 2, since the support portion surrounds the elbow, even if the elbow is about to go outside, the movement may be restricted by the support portion. Further, the supporter described in Patent Document 2 prevents excessive internal rotation and valgus, does not induce external rotation, and may not be able to swing the arm efficiently.

Therefore, it is expected to develop a wearing article with an elbow that is easy to move and can induce external rotation of the shoulder joint.

Therefore, an object of the present invention is to provide a wearing article wearing article that covers the elbow part, which can achieve both the mobility of the wearer and the induction of the external rotation of the shoulder joint.

In order to solve the above-described problems, a feature of the present invention relates to a wearing article that covers the elbow. The wearing article covering the elbow part according to the feature of the present invention is formed of a stretchable material, a main body part covering the elbow part, a proximal attachment part of the biceps brachii and a proximal attachment part of the triceps From the boundary of the humerus to the lateral epicondyle of the humerus, it is provided without circling the upper arm and includes a tightening portion having a tightening force stronger than that of the main body portion.

According to the present invention, it is possible to provide a wearing article wearing article that covers the elbow part, which can achieve both the mobility of the wearer and the induction of the external rotation of the shoulder joint.

In the embodiment of the present invention, the “wearing article covering the elbow” indicates upper body clothing such as a supporter covering the elbow and a sports undershirt. In the embodiment of the present invention, the position related to the worn article may be described in association with the position of bone or muscle, which means “position in the vicinity of bone or muscle”.

(Embodiment)
With reference to FIG. 1 thru | or FIG. 6, the supporter 1 which concerns on embodiment of this invention is demonstrated. The supporter 1 is a wearing article that covers the elbow, and makes it possible to achieve both the ease of movement of the wearer and the efficiency of swinging the arm by guiding the external rotation of the shoulder joint. Although the supporter 1 which concerns on embodiment of this invention demonstrates mainly the object for the right which covers a right elbow, the object for the left which covers a left elbow is formed left-right symmetrically.

The supporter 1 includes a main body portion 2, a main tightening portion 3, and a sub tightening portion 4 as shown in FIGS. As shown in FIG. 3, the wearer may wear both the right supporter 1 and the left supporter 1a, or only one of the right supporter 1 and the left supporter 1a. You may do it.

The supporter 1 according to the embodiment of the present invention will be described with respect to a case where seams are provided in order to form a tubular shape by sewing fabrics formed in a sheet shape, but is not limited thereto. For example, the supporter 1 may be formed by knitting in a tubular shape, or may be formed in a tubular shape by using a hook-and-loop fastener or the like formed from a sheet-shaped fabric.

The main body 2 is a cylindrical member that covers the elbow, and is formed of a stretchable material that follows the movement of the wearer's elbow and the shoulder joint and fits. As shown in FIG. 3, the main body 2 covers from the middle of the upper arm to the wrist, but is not limited thereto. Specifically, the forearm portion may not be covered and the vicinity of the elbow may be covered from the middle of the upper arm, or it may extend further distally from the wrist and cover the hand or finger.

The main body 2 is formed of, for example, a two-weight ricot, a two-way russell, a double raschel, a circular knitting, a knitted fabric using a lace material, a bare tentacle, or the like. The two-weight ricot is composed of, for example, a polyester blend rate of 82.9% and a polyurethane blend rate of 17.1%, but is not limited to this configuration. The main body 2 has a stretch recovery in the warp direction of the fabric (circumferential direction of the main body 2) of about 40 cN to 90 cN, and a stretch recovery in the weft direction of the fabric (longitudinal direction of the main body 2) from 30 cN to 60 cN. A material of a degree is preferable. Elongation recovery is achieved when the test piece is attached to a constant-speed extension type tensile tester, and extension recovery is repeated several times at a speed of about 300 mm / min. It is calculated by the average of resilience (cN). Here, the test piece is 160 mm × 25 mm, and the test piece is attached to a constant speed extension type tensile tester with an upper grip 25 mm, a lower grip 35 mm, and a grip interval 100 mm.

The main tightening portion 3 has a stronger tightening force than the main body portion 2. When the elbow is pulled backward, the main tightening portion 3 pulls the cloth, and guides the shoulder joint in the external rotation direction by a force by which the pulled cloth returns to its original position. As described above, the main tightening portion 3 can efficiently guide the external rotation of the shoulder joint when the elbow is pulled backward rather than applying strong power. A function to induce external rotation can be exhibited.

In the embodiment of the present invention, the main tightening portion 3 will be described with respect to a case where a stretchable belt-like material such as a power net or a tricot is overlapped and fixed to the main body portion 2, but is not limited thereto. The main tightening portion 3 may realize a desired tightening force by changing the knitting structure of the main body portion 2 or performing resin printing. In addition, the fabric of the main tightening portion 3 is not overlapped with the main body 2 but the main tightening portion 3 is sewn together with the main body 2 so that the main tightening portion 3 does not pass through the main body 2 and can be worn by the wearer. It may be formed so as to give a tightening force.

The power net of the main tightening portion 3 used in the embodiment of the present invention has a stretch recovery property in the warp direction (upper arm circumferential direction) of about 60 cN to 150 cN, and is in the weft direction of the fabric (longitudinal direction of the upper arm). A material having an elongation recovery property of about 50 cN to 120 cN is preferable.

The power net of the main tightening portion 3 is preferably fixed to the main body portion 2 by being cut in a direction that does not easily expand and contract in the horizontal direction (the circumferential direction of the upper arm) but easily expands and contracts in the vertical direction (the longitudinal direction of the upper arm). . Thereby, in the longitudinal direction of the upper arm portion of the supporter 1, the fabric easily expands and contracts, and it is possible to give power for guiding the shoulder joint in the external rotation direction.

As shown in FIGS. 4 and 5, the main tightening portion 3 is provided from the boundary P1 between the proximal attachment portion of the biceps brachii and the proximal attachment portion of the triceps brachii to the outer epicondyle P2 of the humerus. . When the elbow is pulled backward, the fabric of the main tightening portion 3 is pulled. The main tightening portion 3 is a force by which the pulled fabric returns to the original contraction, and the outer epicondyle P2 of the humerus with the boundary P1 between the proximal attachment portion of the biceps brachiis and the proximal attachment portion of the triceps surae as a fulcrum. The shoulder joint can be guided in the external rotation direction. As a result, the armpit is closed, so that it is possible to efficiently swing the arm greatly in the front-rear direction. In the supporter 1 according to the embodiment of the present invention, the main tightening portion 3 connects the boundary P1 and the outer humerus outer condyle P2 efficiently without applying tightening in the vicinity of the shoulder joint. Induces turning motion. Therefore, the supporter 1 can induce a sufficient external rotation of the shoulder joint with less power without hindering the movement of the shoulder joint.

Here, the boundary P1 between the proximal adhering portion of the biceps brachii and the proximal adhering portion of the triceps surae where the fulcrum of the main tightening portion 3 is provided is an adhering portion of the muscle, so there is no movement of the muscle. When the fulcrum of the main tightening part 3 is provided directly above the biceps or triceps, the muscle moves by arm movement, the fulcrum is shaken, and the power for guiding the shoulder joint in the external rotation direction is lost. End up. Therefore, in the embodiment of the present invention, by providing the fulcrum of the main tightening portion 3 at the boundary P1 where there is no movement of the muscle, the shaking of the fulcrum is suppressed and the shoulder joint is efficiently guided in the external rotation direction. Make it possible.

Also, the outer humerus epicondyle P2 to which the main tightening portion 3 is connected is located on the outer side of the elbow with the bone raised. Therefore, by providing the main tightening portion 3 from the boundary P1 to the outer humerus condyle P2, it is possible to collect the power of the main tightening portion 3 on the outer humerus condyle P2, so that it is efficient with less power. It is possible to guide the shoulder joint in the external rotation direction.

The main tightening portion 3 is further provided without going around the forearm from the outer epicondyle P2 of the humerus to the ulcer side P3 of the wrist through the distal side of the elbow head P4. By extending the main tightening portion 3 to the wrist side, it is possible to further give power to bring the outer humerus outer condyle P2 closer to the body, so that it is possible to further induce external rotation in the upper arm. In addition, by extending the main tightening portion 3 to the wrist side, it is possible to avoid a state in which the outer humerus outer condyle P2 is not properly tightened due to the displacement caused by the movement of the elbow joint, and to tighten the outer humerus outer condyle P2. enable. Further, by disposing the main tightening portion 3 while avoiding the elbow head P4, it is possible to avoid a state in which the elbow head P4 is difficult to move and the elbow is difficult to bend and stretch by the tightening force of the main tightening portion 3. it can.

Further, the wrist scale side P3 where the main tightening portion 3 is provided, that is, the vicinity of the lower part of the little finger is a fulcrum for the pronation and supination of the wrist, so there is little movement. Therefore, by providing the main tightening portion 3 on the wrist scale side P3, there is little displacement due to movement of the arm or wrist, and it is possible to prevent the displacement due to movement of the forearm.

The main tightening portion 3 is formed in a band shape, a band-shaped short direction is disposed in the circumferential direction of the arm, and a band-shaped long direction is disposed in the longitudinal direction of the arm. The lateral direction of the band-like proximal side of the main tightening portion 3 corresponds to the proximal attachment portion of the biceps brachii from the boundary P1 between the proximal attachment portion of the biceps brachiis and the proximal attachment portion of the triceps It is provided in the position to do. Here, it is preferable that the upper end of the main tightening portion 3 is not disposed so as to straddle the biceps brachii and triceps brachii, but is disposed so that the corner of the upper end corresponds to the boundary P1. Thereby, the shake of the fulcrum at the boundary P1 can be suppressed. In the example shown in FIG. 4, the upper end of the main tightening portion 3 is provided from the boundary P1 to the biceps brachii. In the embodiment of the present invention, the upper end of the main tightening portion 3 is disposed so as to have a length of about 5 to 10 centimeters when placed flat, but is not limited to this range, and the main tightening portion 3 is formed. It is adjusted as appropriate depending on the material to be used and the required tightening force.

Further, the short-side direction of the band-like distal side of the main tightening portion 3 is provided at a position corresponding to the palm side from the scale side P3 of the wrist. By providing the main tightening portion 3 on the palm side of the wrist, it is difficult to be affected by the movement of the skin due to palm flexion and dorsiflexion of the wrist, and it is possible to prevent the main tightening portion 3 from being displaced. In the embodiment of the present invention, the lower end of the main tightening portion 3 is disposed so as to have a length of about 3 to 5 cm when placed flat, but the main tightening portion 3 is not limited to this range. It is adjusted as appropriate depending on the material to be used and the required tightening force.

The portion provided on the upper arm of the main tightening portion 3 is formed to have a stronger tightening force than the portion provided on the forearm. Here, if the tightening of the forearm is strengthened, the external rotation of the shoulder joint is restricted, and the pronation and pronation of the wrist are restricted. Therefore, by weakening the tightening of the forearm, it is possible to act so as not to hinder the external rotation of the shoulder joint without hindering the movement of the wrist joint.

The main tightening portion 3 according to the embodiment of the present invention adjusts the strength of the tightening force according to the width (the length in the short direction or the length in the circumferential direction) of the belt-shaped member forming the main tightening portion 3. That is, the main tightening portion 3 is formed to be thick on the upper arm and thin on the forearm. In addition, the strength of the tightening force may be adjusted by changing the knitted fabric at the upper arm and forearm positions of the main tightening portion 3 or changing the amount, density, material, etc. of the resin print.

Here, the main tightening portion 3 is provided without circling the upper arm, is provided without circling the forearm, and is provided so that the upper arm or the forearm is gently circulated around the entire supporter 1. As shown in FIG. 3 and the like, the main tightening portion 3 (dark hatch portion) of the supporter 1 according to the embodiment of the present invention passes from the inner side of the forearm to the distal side of the elbow head P4 to the palm side of the wrist. It is formed so as to gently go around the arm about one round. In this manner, the main tightening portion 3 is formed so as not to circulate around the arm many times, so that natural arm swinging can be realized without hindering movement.

The secondary tightening portion 4 has a stronger tightening force than the main body portion 2 and a weaker tightening force than the main tightening portion 3. The secondary tightening portion 4 is connected to the main tightening portion 3 by the forearm from the boundary P1 between the proximal attachment portion of the biceps brachii and the proximal attachment portion of the triceps brachii, passing through the proximal side from the elbow head P4. Provided. The auxiliary tightening portion 4 supports the external rotation guidance by the main tightening portion 3. Specifically, as shown in FIG. 6, the main tightening portion 3 and the sub-tightening portion 4 are disposed so as to sandwich the elbow head P4 while avoiding the elbow head P4. The elbow can be bent without being affected by the tightening force of 3 and the sub-tightening portion 4. Further, since the main tightening portion 3 and the sub tightening portion 4 are formed so as to sandwich the elbow head P4, it is possible to avoid displacement of the positions of the main tightening portion 3 and the sub tightening portion 4 due to the protrusion of the elbow head P4. it can. Therefore, the secondary tightening portion 4 can make it difficult to shift the position to which the main tightening portion 3 applies the tightening force, and the main tightening portion 3 can appropriately tighten the boundary P1 and the outer humerus epicondyle P2.

The auxiliary tightening portion 4 is formed so as to connect to the main tightening portion 3 in the middle of the forearm through the proximal direction of the elbow head from the inner side of the upper arm and gently turn the arm slightly less than one round. As described above, the secondary tightening portion 4 can realize natural arm swinging without hindering the ease of movement, like the main tightening portion 3.

Referring to FIG. 7 and FIG. 8, the effect of opening the elbow and pulling the elbow will be described. As shown in FIG. 7 (a), the opening of the elbow is represented by the angle of the vertical line passing through the base of the neck and the line connecting the base of the neck and the elbow head P4 when the wearer is viewed from the back. . As shown in FIG. 7 (b), the elbow pull is represented by the angle between the vertical line passing through the shoulder cap and the line connecting the shoulder cap and the elbow head P4 when the wearer is viewed from the side.

Fig. 8 (a) is a diagram comparing the opening of the elbow of the supporter 1 according to the embodiment of the present invention and Fig. 8 (b) is a diagram comparing the pull of the elbow. Here, the comparative product is a supporter of only the main body portion 2 that does not have the main tightening portion 3 and the sub tightening portion 4. As shown to Fig.8 (a), the opening of the elbow of the supporter 1 which concerns on embodiment of this invention reduces about 2% compared with a comparative product, and has the effect of bringing an elbow closer to the body side and closing an armpit. I know that there is. As shown in FIG. 8 (b), it can be seen that the elbow pull of the supporter 1 according to the embodiment of the present invention is increased by about 10% as compared with the comparative product, and has an effect of pulling the elbow far backward. .

From FIG. 8, the supporter 1 according to the embodiment of the present invention can be guided to tighten the armpits and pull the elbow backward, thus supporting effective arm swing and improving the forward propulsive force. It turns out that there is an effect.

The supporter 1 according to the embodiment of the present invention includes a body portion 2 having elasticity, a boundary P1 between the proximal attachment portion of the biceps brachii and the proximal attachment portion of the triceps brachii, and the humerus A main tightening portion 3 for providing a tightening force to the lateral epicondyle P2 is disposed. As a result, when the elbow is pulled backward, the supporter 1 can extend the main tightening portion 3, generate a tensile force by the return force of the main tightening portion 3, and guide the external rotation of the shoulder joint. In this way, instead of always applying strong power, the external rotation of the shoulder joint can be guided when the elbow is pulled backward, so that the movement of the shoulder joint can be efficiently performed without hindering movement. Can be guided.
