Hereinafter, the present invention will be described in detail based on the drawings showing the embodiments.
As shown in FIG. 1, the posture correction tool of the present invention is made of an elastic body 1 that is entirely stretchable, and the width dimension W ₀ of the left and right center region 2 is narrowed with respect to the width dimension W _{1 of} both left and right ends in free state. A closed annular band portion 3 having a necked shape and a connecting portion 4 for connecting the band portions 3 in the left and right central regions 2 are integrally formed. As shown in FIG. 6, the posture correction tool of the present invention is mounted in an extended state by putting the band 3 over the back of the user (from the top of the clothes) and is mounted in an extended state, and the band 3 maintains the extended state. However, it can be rephrased as a posture holder configured to draw the user's scapula to the center by elastic force F ₁ , F ₂ , and maintain the user's posture properly.
The elastic body 1 is, for example, a thermoplastic rubber (TPR) or a thermoplastic elastomer (TPE), and the hardness measured using a TYPE A tester specified in JIS K7312 is set to A2 to A12. There is. Preferably, the hardness is set to A3 to A9. That is, the elastic body 1 is very soft like jelly confectionery, and the closed annular band portion 3 is formed so as to be elastically deformed by a small force so as to be easily stretched.

As shown in FIGS. 2 and 3, the band portion 3 has a flat portion 6 near the left and right central region 2, and the flat portion 6 is formed in a cross-sectional oval shape (see FIG. 4).
In the mounted state shown in FIG. 6, although it will necessarily twist to the band part 3, the flat part 6 is comprised so that it may contact | abut along a back, and the flat part 6 uses it with a loose curved curved surface. The contact surface pressure is small and it feels as if it is weak because it abuts on the back side of the person, and the uncomfortable feeling at the time of wearing is reduced. Moreover, since the flat part 6 contacts in a wide area, the frictional force with respect to clothes improves and it becomes difficult to produce a slip further. Therefore, even if the user wears the posture correction tool of the present invention, the user does not shift even if the user walks or plays sports such as golf while wearing the posture correction tool of the present invention. Resilient forces F ₁ and F ₂ are applied so that the user can wear without discomfort and keep the user in the correct posture.

Moreover, the band part 3 has the

bending parts

7 and 7 in right-and-left both ends, and the bending part 7 is formed in cross-sectional polygon shape (refer FIG. 5). The cross section of the curved portion 7 may be circular.
The

bent portions

7, 7 absorb the twisting which inevitably occurs in the band portion 3 during mounting, and even if the

curved portions

7, 7 having a polygonal cross-sectional circular shape are twisted, the feeling of contact with the shoulder is small. Do not feel pain in the shoulders, even after prolonged use.

As shown in FIG. 1, the connecting portion 4 includes two

bridges

8 and 8 arranged in a V shape.
The

bridges

8, 8 have a circular cross section or a polygonal shape (not shown), and are integrally connected to the band 3. A trapezoidal window 9 is formed inside the H-

shaped bridges

8, 8. The window portion 9 may be in the form of penetration or may be in the form of non-penetration with a thin film remaining. A pair of left and right ladder-

shaped window parts

5 and 5 is formed on the outside of the two bridges 8 and 8 (connection part 4).

When drawing the user's scapula to the center of the back, the band 3 applies a friction coefficient to the surface of the band 3 so as not to cause the user's clothes to slip.
In the worn state, the band portion 3 is in contact with the clothes worn by the user, and the surface friction of the elastic body 1 such as thermoplastic rubber (TPR) or thermoplastic elastomer (TPE) makes the slip against the clothes It does not occur. In addition, as clothes of a user, underwear and a functional inner which adheres to a body are preferable.

The usage method (action) of the posture correction tool of this invention mentioned above is demonstrated.
In the posture correction tool of the present invention, the left and right end portions of the band 3 are pulled outward so as to be in an extended state, and the wrist is turned while moving around from above the head and moved to the back side. The center region 2 is applied to the lower shoulder blade through the arms in the

windows

5 and 5 so as to correspond to the center of the back, and is mounted as shown in FIG.
The band portion 3 draws the user's scapula to the center with elastic forces F ₁ and F ₂ which are about to return from the extended state. At this time, in the central region 2, as shown in FIG. 7, the band portion 3 is extended to the left and right, the trapezoidal window 9 is expanded to the left and right, and the two

bridges

8 and 8 are extended. , 8 generate elastic tensile forces T _c and T _c . That is, elastic forces F ₁ and F ₁ are generated by the combined forces of the tensile forces T _A and T _A generated in the upper band 3 of the central region 2 and the tensile forces T _C and T _C of the

bridges

8 and 8 In addition, elastic forces F ₂ and F ₂ are generated by the combined forces of the tensile forces T _B and T _B generated in the lower band 3 of the central region 2 and the tensile forces T _C and T _C of the

bridges

8 and 8. , Pull the scapula back to the center.

The band portion 3 abuts the clothes in a sufficiently stretched state, and maintains the stretched state without causing the clothes to slip even after wearing. In the band portion 3, the

flat portions

6, 6 disposed near the central region 2 extend well, and the

flat portions

6, 6 are maintained in an extended state by friction with clothes, so Pulling is exhibited strongly. On the other hand, the band portion 3 is restored to a state in which the

curved portions

7, 7 at the left and right both ends are slightly extended or almost restored, and is hung on the shoulder, and the left and right ends (curved portions 7, 7) The hit on both shoulders of the user is weak and does not cause any pain. That is, since the band portion 3 is provided with a friction coefficient that does not cause slippage on the clothes on the surface, the

flat portions

6 and 6 near the central region 2 and the

bent portions

7 and 7 at both left and right end stretch. The

flat portions

6, 6 extend well and are locally relatively strong in tension, and the tension in the portions of the

curved portions

7, 7 remains relatively weak. Therefore, the band 3 does not pull the user's shoulders backward (as in the prior art), but (as in the posture correction tool of the present invention) along the movable direction of the shoulder joint as indicated by arrow R in the figure. The tension force is applied, the user stretches the chest and raises the eyes, and the elastic force F ₁ and F ₂ that pulls the scapula to the center of the back act to ensure the spine of the user Stretch out and keep it in the correct position.

Next, the posture correction tool set of the present invention will be described.
As shown in FIG. 8, it is formed of stretchable elastic bodies 1 and is composed of a uniform set of posture correction tools H, M, S having the same shape in the free state and having different hardnesses of the elastic bodies 1.
Posture correction tools H, M and S are classified into three types of hardness: “hard”, “medium” and “soft”, and in the free state, the width dimension W ₀ of the left and right central area 2 is narrowed to narrow. The closed annular band portion 3 having the same shape and the connecting portion 4 for connecting the band portions 3 in the left and right central regions 2 are integrally formed, and the band portions 3 are oval in cross section near the left and right central regions 2 And the

curved portions

7 and 7 having a polygonal or circular cross section at the left and right ends. The connecting portion 4 has two

bridges

8 and 8 arranged in a V-shape, and a trapezoidal window 9 is formed inside the

bridges

8 and 8, and outside the

bridges

8 and 8. The left and right pair of ladder-shaped

windows

5, 5 are formed.
The elastic body 1 is made of, for example, a thermoplastic rubber (TPR) or a thermoplastic elastomer (TPE). For posture correction tools H, M and S, the hardness measured using a TYPE A tester specified in JIS K7312 is set to A12 to A8 in "hard", and to A7 to A5 in "medium". , "Soft" is set to A4-A2. Preferably, "hard" is set to hardness A9, "medium" is set to hardness A6, and "soft" is set to hardness A3. The posture correction tools H, M, and S are provided with a friction coefficient that does not cause slippage on clothes, on the surface of the band portion 3.

As shown in FIG. 9, the uniform posture correction tools H, M and S are configured such that elastic forces F ₁ and F ₂ with respect to extension of the elastic body 1 are different when the same person wears them. There is.
As shown in FIG. 9A, the “hard” posture correction tool H exerts elastic forces F ₁ and F ₂ that pull the scapula strongly toward the center. That is, the posture correction tool H is worn when playing sports such as golf, tennis, baseball, soccer, yoga or the like, or is selected in accordance with the physical size such as a narrow shoulder width. The “medium” posture correction tool M has smaller elastic forces F ₁ and F ₂ than “hard” and is suitable for light exercise such as jogging or walking. The “soft” posture correction tool H exerts elastic forces F ₁ and F ₂ that pull the scapula weakly toward the center. The “soft” posture correction tool H is suitable for wearing for a long time in daily life, and has an advantage that it has a weak tightening feeling (restraint feeling) and is less tired.

In the present invention, the design can be changed, and for example, in the connecting portion 4, the two

bridges

8 and 8 may cross in an X shape and the middle portions may be integrated with each other, or The part 4 may have two or more bridges 8.

As described above, the posture correction tool according to the present invention comprises the elastic body 1 that is entirely stretchable, and the closed annular band portion having a shape in which the width dimension W ₀ of the central region 2 in the left-right direction is narrowed in the free state. 3 and the connecting part 4 connecting the band part 3 in the central region 2 are integrally formed, and in the wearing state, the band part 3 is hung from the back side of the user on both shoulders and maintains the extended state While, it is configured to draw the user's scapula to the center of the back with elastic force F ₁ , F ₂ so that the elastic body 1 is soft, can be worn without pain, and can be moved Because it has a high degree of freedom and fatigue resistance, it can be used comfortably for a long time. The elastic force F ₁ , F ₂ acting to draw the scapula can stretch the user's spine and maintain the correct posture.

Further, in a free state, the width W ₁ from the left and right end portions to the central region 2 for curved arcuately gradually decreases and the central region 2 is narrowed down to a minimum width dimension W ₀ constricted closed circular band portion 3 and a connecting portion 4 connecting the central region 2 of the band portion 3 up and down, and a pair of left and right window portions 5 and 5 are formed by the band portion 3 and the connecting portion 4 so that the heat is soft The whole is integrally formed with a stretchable elastic body 1 made of a plastic elastomer, and the left and right ends of the band 3 are hooked from the back side to both shoulders through the user's arms through the windows 5, 5 in mounting the mounted state, the elastic force F ₁ from the top of the left and right end portions of the right and left inward slanting downward to the central region 2 the band 3 is generated, and the central area from the lower part of the left and right end portions The elastic force F ₂ to the left and right inward is generated in ₂ Since the user's scapula is drawn to the center of the back with the forces F ₁ and F ₂ , the elastic body 1 is soft, can be worn without pain, and has a high degree of freedom of movement. As it is less tired, it can be used comfortably for a long time. The elastic force F ₁ , F ₂ acting to draw the scapula can stretch the user's spine and maintain the correct posture.

In addition, the band portion 3 has the flat portion 6 having a cross-sectional oval shape near the left and right central region 2 and the flat portion 6 is in contact with the back in the mounted state, so that the flat portion 6 has a loose curve Since it is in contact with the back side of the user with a wedge-shaped curved surface, the contact surface pressure is small and it feels as if it is weak and it can reduce discomfort when worn. In addition, since the flat portion 6 contacts in a wide area, it does not easily slip on clothes, and does not shift even when worn over a long period of time, so that the resilient force F ₁ is maintained so that the user maintains the correct posture. , F ₂ can be given. Even when the user walks or plays sports such as golf, the user can wear without any positional deviation and without discomfort.

Further, since the band portion 3 has the

bent portions

7 and 7 having a polygonal or circular cross section at both left and right end portions, it is possible to absorb the twist inevitably generated in the band portion 3 at the time of mounting, and the bent portion The feeling of impact on the shoulders of 7, 7 is small and it can be used for a long time without feeling pain in the shoulders.

Moreover, since the connection part 4 has the two

bridges

8 and 8 arrange | positioned in the shape of H shape, the band part 3 and the

bridges

8 and 8 cooperate, and a scapula is on the back center. Elastic forces F ₁ and F ₂ are generated to draw the user's spine securely and maintain the correct posture.

In addition, when drawing the user's scapula to the center of the back, the band 3 applied a friction coefficient to the surface of the band 3 so as not to slide on the user's clothes. The

flat portions

6, 6 are well stretched and the tension is relatively strong locally, and the

flat portions

6, 7 and 7 of the left and right ends do not have uniform elongation. Keeping the tension of the part relatively weak, the band 3 opens the user's shoulders to raise the line of sight, and exerts an elastic force F ₁ or F ₂ that pulls the scapula to the center of the back Ensure that the user's spine is stretched and kept in the correct posture.
