Description

  The present invention relates to an improvement in a posture correction supporter for preventing stiff shoulders and back pain.

  In daily life, various supporters have been devised as countermeasures against stiff shoulders and back pain caused by poor posture, such as being bent forward during walking and daily work. Yes.

  For example, as shown in FIGS. 1 and 2, the supporter described in Patent Document 1 has a chest belt 1 wound around the lower pectoral muscle from the back side, and one end at the upper center on the back side of the chest belt 1. Is provided, and the other end is provided with shoulder belts 2 and 3 that are adjusted and fixed at positions closer to the back of the body side than the back from the back side over the shoulder.

In such a supporter, the shoulder belts 2 and 3 may bite into the armpit during posture correction, and it may be difficult to continue wearing due to pain.
Therefore, a supporter like Patent Document 2 has been proposed.
As shown in FIGS. 1 and 4, this supporter has a chest belt 3 that extends horizontally, one end fixed to the back side of the chest belt 3, and a pair of shoulder belts having elasticity that extends across each other. 2, and the other end is suspended from the front surface (front surface) of the body in parallel to each other and fixed to the chest belt 3.
In such a supporter, since the chest belt 3 extends along the bust line, the shoulder belt 2 does not bite under the heel and has an advantage that the heel does not hurt during wearing.

However, in the thing of patent document 2, although a shoulder belt does not bite into the armpit surely, it has the following faults.
FIG. 10 shows a state where the shoulder belt is fixed to the belt at a position in front of the body.
In this case, the user's shoulder is pulled downward as indicated by the arrow due to the stretching force of the shoulder belt, and therefore the action of pulling up in the direction of the back and correcting the forward bending posture is not sufficiently exhibited.
Not only that, but with regard to the wearer's body shape, there is a drawback in that when the chest and abdomen are particularly “thick”, the shoulders are pulled forward, resulting in so-called “stoop”. .

  The present invention has been made to solve the above-described problems, and by attaching, the shoulder belt does not bite under the heel, so that a tension for correcting a forward bending posture that causes stiff shoulders and low back pain can be applied. It aims to provide a supporter for posture correction.

  In the present invention, the above object is achieved by a back support portion formed of a plate-like body having a large area so as to form a back body substantially inside both shoulder blades, and a lower end of the back support portion. A main body belt that extends horizontally and wraps around to the position of the underbust; a pair of auxiliary belts that extend from the upper end of the back support portion, wrap around the front of the body, and extend downward; and the main body belt This is achieved by a posture correction supporter that is provided on both sides of the belt and includes locking means for locking the auxiliary belt.

According to the above configuration, the back support portion, which is a plate-shaped main body having a large area, is brought into contact with the region including the upper back of the wearer, so that the force transmitted from the auxiliary belt is received over a wide area. be able to. For this reason, sufficient supporting force can be exhibited.
Further, since the main body belt extends at the position of the underbust, when the pulling force of the auxiliary belt is transmitted, the main body belt does not bite under the wearer's heel, so that there is no pain at the time of wearing. Here, “turning to the position of the underbust” means to be disposed in the waistline direction at least at a position lower than the bust position.
In addition, the auxiliary belt that extends from the upper end of the back support portion and is rotated to the front of the body has its tip locked to both sides of the main body belt, so the auxiliary belt that hits the front of the shoulder of the wearer is By pulling the shoulder toward the back support, the upper front of the body is raised, and the forward bending posture is effectively corrected.
That is, when the auxiliary belt is guided almost perpendicularly to the front surface of the body and fixed to a belt such as a main body belt, the shoulder portion is pulled downward by the pulling force of the auxiliary belt, and the posture is deteriorated. In some cases, the present invention does not have such a harmful effect.

In the present invention, it is preferable that the auxiliary belt is arranged so as to intersect with the inside of the back support part or the surface opposite to the body contact surface of the back support part. To do.
According to the above configuration, the pulling force of the auxiliary belt can be transmitted to the back support portion in a hooked state, so that the upper back muscles can be assisted and the wearer's shoulder can be effectively caused. The bent posture can be corrected appropriately.

In the present invention, it is preferable that a non-expandable portion is provided at a fixed length on the tip side of the auxiliary belt.
According to the said structure, compared with the case where the full length of an auxiliary belt expands and contracts, the site | part from a wearer's shoulder part to a back can be pulled more effectively.
In addition, since the auxiliary belt is folded at the top of the shoulder portion, when the entire length of the auxiliary belt is expanded and contracted, tension is concentrated at the folded portion, but the auxiliary belt extends from the shoulder portion to the back portion. By extending and contracting, such a situation can be prevented and an effective tension for posture correction can be obtained.

In the present invention, it is preferable that the locking means for the main body belt is formed on both sides of the main body belt and passes the front end side toward the lower side of the auxiliary belt, and the direction of the front end side is set. A locking ring that leads in a direction along the main body belt, a locking portion that is formed at the tip of the auxiliary belt, and a locked portion that is formed on the surface of the main belt.
According to the above configuration, since the auxiliary belt can be easily guided to both sides (body side) of the wearer's body, the auxiliary belt does not bite under the heel, and the loop around the shoulder formed by the auxiliary belt is wide. It is easy for the wearer to pass the arm, and the front end side of the auxiliary belt is passed through a locking ring so that it is folded forward from both sides of the body and overlapped with the direction in which the main body belt extends. The locking portion formed at the tip of the belt can be locked to the locked portion formed on the surface of the main body belt, and can be fixed while easily adjusting the pulling force of the auxiliary belt.

In the present invention, preferably, the main body belt is configured to be detachable along the underbust portion so as to be adjustable in length in the horizontal direction.
According to the said structure, the clamping force of a main body belt can be adjusted easily easily, and it is easy to adapt it to a wearer's body size.

In the present invention, it is preferable that the locking portion of the auxiliary belt is an arbitrary portion in the length direction with respect to the locked portion formed in a wide range along the length direction of the main body belt. It is characterized by being configured to be detachable at a position.
According to the above-described configuration, the auxiliary belt can be adjusted in a wide range because it can be locked to a locked portion formed in a wide range along the length direction of the main body belt. .

In the present invention, it is preferable that an anti-slip portion is formed at the lower end of the back support portion on the body side where the back support portion abuts.
According to the above configuration, the back support portion is unlikely to be displaced with respect to the back surface of the wearer's body, so that the correction force can be effectively applied without the tension of the auxiliary belt being loosened.

In the present invention, it is preferable that the main body belt extends toward the both sides at the lower end of the back support portion, and the anti-slip is provided at each extended base end position of the main body belt. A portion is formed.
According to the above configuration, it is possible to make it difficult for the rear support portion and the main body belt to be displaced.

  As described above, according to the present invention, the posture-correcting posture can be applied to correct the forward bending posture that causes stiff shoulders and low back pain without wearing the shoulder belt under the heel. Supporters can be provided.

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
The embodiments described below are preferable specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention particularly limits the present invention in the following description. As long as there is no description of the effect, it is not restricted to these aspects.

  FIG. 1 is a schematic perspective view showing a state in which a posture correction supporter (hereinafter referred to as “supporter”) according to an embodiment of the present invention is mounted, and FIG. 2 is a rear view thereof. FIG. 3 is a development view of the supporter of the present embodiment as viewed from the front side, and FIG. 4 is a development view of the supporter of the present embodiment as viewed from the back side.

  As shown in FIG. 2, the supporter 10 includes a back support 11 that is a plate-like main body having a large area so as to form a back body substantially inside the shoulder blades in the mounted state, A main body belt 21 that extends horizontally from the lower end of the support portion 11 and wraps around to the position of the underbust, and has elastic elasticity that extends from the upper end of the back support portion 11 and wraps around the front of the body, and the distal end side extends downward. A pair of auxiliary belts 31, 31 and locking means set on both sides of the main body belt and including locking rings 32, 32 for locking the auxiliary belt.

The back support portion 11 is a main body of the supporter 10 and has a predetermined area so as to cover, for example, the inner periphery of both shoulder blades at the center of the wearer's back as shown in FIG. In this way, it spreads vertically and forms a back body. Thereby, the back surface support portion 11 is brought into contact with the back in a wide area including the upper back portion, and can receive and support the tension of the auxiliary belt described later.
In the present embodiment, the back support portion 11 is preferably formed into a plate shape by superposing at least two materials of a front surface portion and a back surface portion.

For example, 100% nylon mesh (fishnet) material is used as the surface material 11a shown in FIG. 3, and a hard power net made of 85% nylon and 15% polyurethane is used as the back material 11b shown in FIG. It is fixed by polymerization. As a result, the portion is provided with rigidity for receiving a pulling force from the auxiliary belt or the main body belt and a certain degree of elasticity that fits the body appropriately and does not cause discomfort. Moreover, the back support portion 11 is a portion that comes into contact with the back, but since the surface material 11a is a mesh material, the air permeability is extremely good.
The back support 11 may be formed by polymerizing two or more materials. For example, in addition to the surface material and the back material, a core material having relatively high rigidity may be disposed between them.

A pair of wide belts 22 and 23 extending horizontally to the sides are connected to the lower end or lower part of the back support 11 at the positions 13 and 13 in FIG. A main body belt 21 is configured.
As shown in FIGS. 1 and 2, the main body belt 21 may be formed at a position where it can be placed in the vicinity of the wearer's underbust when the supporter 10 is worn in relation to the back support portion 11. It needs to be lower than the underbust, but higher positions are not preferred.

The main body belt 21 is formed of a wide rubber tape or the like which is rich in elasticity as a whole, and as shown in FIG. 24, 24 are formed.
On the other hand, as shown in FIG. 4, a locking portion 25 is formed by a male member of a hook-and-loop fastener at the tip of the back surface of the belt 23.
Further, as shown by reference numerals 34 and 34, anti-slip portions are formed on the body side of the back support portion 11 corresponding to the base end portions where the belts 22 and 23 extend. In this embodiment, the anti-slip portions 34 and 34 are formed by disposing a strip-shaped rubber material. However, the anti-slip portion may be formed by making the surface rough, for example.

Cuts 14 and 14 are formed in a part of the surface material 11a from the upper end of the back support part 11, and a pair of auxiliary belts 31 and 31 are exposed and extended to the outside.
Specifically, the auxiliary belts 31, 31 have their lower end on the back support part side fixed by sewing or the like at locations 13 and 13 in FIG. 3, and the inside of the back support part 11 (surface material 11 a and back face) Between the materials 11b), and the extending side extends from the cuts 14 and 14 to the outside.

The auxiliary belts 31 and 31 are exposed to the outside and then hung downward, and the respective front end portions are locked to the main body belt 21, whereby the auxiliary belts 31 and 31 are shown in FIG. Like, make a loop around the shoulder.
The auxiliary belts 31 and 31 are provided with elastic stretchability. In this embodiment, the auxiliary belts 31 and 31 are made of pile rubber having high elastic stretchability as a whole.
As shown in FIG. 3, locking portions 36, 36 are formed at the distal ends of the auxiliary belts 31, 31. The locking portions 36, 36 are provided with a male member of a hook-and-loop fastener on the back surface and a female member of a hook-and-loop fastener on the front surface, and are attached to or detached from the locked portions 24 and 24 on the surface of the main body belt 21 described above. The locking portions 36, 36 can be attached and detached.

Here, as shown in FIGS. 1 and 3, the main body belt 21 is provided with locking rings 32 and 32 at positions corresponding to both side portions (body side) of the wearer's body when the supporter 10 is mounted. Is provided.
The locking ring 32 is, for example, an oval resin ring, and includes a ring-shaped portion through which the auxiliary belt 31 can be passed. As shown in FIG. 3, the locking rings 32, 32 are fixed to the main body belts 21, 21 with their outer sides inclined slightly upward.

Moreover, a non-stretchable portion is provided at a fixed length on the tip side of the auxiliary belts 31 and 31. In the present embodiment, the non-stretchable part is preferably 1/2 to 1/3 of the length extending from the back support part of the auxiliary belt 31 as shown in FIG. Formed on the side.
That is, as shown by reference numerals 35 and 35 in FIG. 4, the auxiliary belts 31 and 31 are entirely formed of an elastic material as described above, and do not expand and contract within a certain length range on the tip side of the auxiliary belts 31 and 31. It is formed by fixing the materials 35 and 35.
In this way, the auxiliary belts 31 and 31 of the supporter 10 can easily realize a structure in which only the back surface expands and contracts from the vicinity of the shoulder and the front end side does not expand and contract, and the expansion and contraction range thereof is adjusted. Is also easy.

FIG. 5 is an explanatory diagram for explaining the operation of the supporter of the present embodiment on the shoulder of the body, FIG. 6 is a diagram showing the arrangement of human muscles related to FIG. 5, and FIG. 7 is the implementation on the back side of the body. FIG. 8 is a diagram illustrating the arrangement of muscles of the human body related to FIG. 7, and FIG. 9 is an explanatory diagram for explaining the advantages of the supporter according to this embodiment in the wearing state. It is.
With reference to these drawings, the operation of the supporter 10 of the present embodiment will be described.

FIG. 5 is a perspective view of a state in which the supporter 10 is worn, and FIG. 6 is a diagram for explaining the relationship between the stiff shoulder and the muscles of the shoulder and the back.
FIG. 6 illustrates the musculature of the shallow portion of the back, and the trapezius muscle shown here is deeply related to the stiff shoulders.
The trapezius muscle is a large muscle formed from the shoulder to the back as shown in the figure, and is a pair of left and right.
Each of the trapezius muscles supports the weight of the left and right arms, which is about 10 kilos in total. In this state, if the posture such as the back of the stoop is deteriorated, the burden on the trapezius muscles is increased, and the muscles are fatigued to cause stiff shoulders.
As shown in FIG. 5, the supporter 10 prevents the stiff shoulder by correcting the forward leaning posture by causing the auxiliary belt 31 to effectively raise the shoulder as shown by the arrow by the action described later. It is something that can be done.

FIG. 8 shows the muscular tissue in the deep part of the back, and the spine standing muscle, which is a general term of the illustrated head plate muscle, spine muscle, etc. I'm in charge. If this spine standing muscle is weak, the posture worsens, and the forward bending posture causes low back pain. In particular, according to the study by the present inventors, it has been found that muscle fatigue at the upper back of the spine erectal muscle is closely related to the cause of low back pain.
Therefore, in the supporter 10, as shown in FIG. 7, in the back support part 11, the auxiliary belts 31, 31 are accommodated in a crossed state, so that the plate-like back support part 11 is pressed against the upper back and weakened. It assists the muscles to prevent a forward bending posture and, in turn, to prevent back pain.

  In the supporter 10, as described above, the back support portion 11, which is a plate-shaped main body having a large area, is brought into contact with the wearer's back, so that the force transmitted from the auxiliary belts 31, 31 is transmitted to the upper back portion. Can be received in a wide area including. For this reason, it is possible to assist the muscles in the upper back and exert a sufficient supporting force.

Further, as shown in FIG. 9, the main body belt 21 of the supporter 10 extends at the position of the wearer's underbust, so when the pulling force of the auxiliary belts 31, 31 is transmitted, it bites under the wearer's heel. There is no pain when wearing.
In this case, since the main body belt 21 is configured to be attached / detached along the underbust portion so that the length thereof can be adjusted in the horizontal direction, the tightening force of the main body belt 21 can be easily adjusted as appropriate. Easy to adapt to size.

In addition, the auxiliary belts 31 and 31 that extend from the upper end of the back support 11 and are rotated to the front of the body are locked at locations corresponding to both side portions (body side) of the wearer's body. As explained in FIG. 5, the auxiliary belts 31 and 31 that hit the front of the shoulder of the wearer pull the shoulder toward the back support 11 as indicated by the arrow, thereby causing the upper front of the body to be raised. By reducing the burden on the trapezius muscle, the forward bending posture is effectively corrected.
That is, when the auxiliary belt is guided almost perpendicularly to the front surface of the body and fixed to the belt such as the main body belt, that is, in the state shown in FIG. 10, the shoulder portion is turned downward by the pulling force of the auxiliary belt. However, the supporter 10 does not have such an adverse effect.

In addition, as described with reference to FIG. 7, the tension of the auxiliary belts 31 and 31 can be transmitted to the back support unit 11 in a hooked state, so that the upper back muscles are assisted and the shoulders are effectively caused. Therefore, the forward bending posture can be preferably corrected.
Further, non-expandable portions 35, 35 are provided at a fixed length on the tip side of the auxiliary belts 31, 31. For this reason, compared with the case where the full length of the auxiliary | assistant belts 31 and 31 expands and contracts, a tension | pulling force can be concentrated locally on the site | part from a wearer's shoulder part to a back, and it can pull more effectively.
That is, since the auxiliary belts 31 and 31 are folded at the tops of the shoulders, when the full length of the auxiliary belts 31 and 31 expands and contracts, tension concentrates on the folded portions. By extending and contracting from the shoulder portion to the back portion, such a situation can be prevented and an effective tension for posture correction can be obtained.

Further, as shown in FIGS. 1 and 3, the locking means of the main body belt 21 is formed on both side portions of the main body belt 21, and passes the front end side toward the lower side of the auxiliary belts 31 and 31. Locking rings 32 and 32 for guiding the direction in a direction along the main body belt, locking portions 25 and 25 formed at the front ends of the auxiliary belts 31 and 31, and a locked portion 24 formed on the surface of the main body belt And.
With such a configuration, the auxiliary belts 31, 31 exhibiting the stretching force can be easily guided to both sides of the wearer's body, and the distal end side, which is the lower end side of the auxiliary belts 31, 31, is used for locking. By passing through the rings 32, 32, it is folded forward from both sides of the body and overlapped with the direction in which the main body belt 21 extends, so that the locking portions 36, 36 formed at the distal ends of the auxiliary belts 31, 31 It can be locked to the locked portion formed on the surface of the main body belt 21, and the tensile force can be easily adjusted and fixed.

As shown in FIG. 1, the locking portions 36, 36 of the auxiliary belts 31, 31 are longer than the locked portions 24 formed in a wide range along the length direction of the main body belt 21. Since it is attached and detached at an arbitrary position in the vertical direction, tension adjustment of the auxiliary belts 31 and 31 is possible in a wide range.
In addition, near the lower end of the back support 11, anti-slip portions 34 are formed on the body side with which the back support 11 abuts. For this reason, since the back surface support part 11 is hard to be displaced with respect to the back surface of the wearer's body, the correction force can be effectively applied without the tension of the auxiliary belts 31 and 31 being loosened.
In particular, since the anti-slip portions 34 and 34 are formed at the extended base end positions of the main body belt 21, both the back support portion 11 and the main body belt 21 can be hardly displaced.

The present invention is not limited to the embodiment described above.
The back support 11 is not limited to the shape described above, and may have other shapes, and other materials can be used as appropriate.
The auxiliary belts 31 and 31 may be one belt by connecting a stretchable one and a non-stretchable one, without forming the whole with a stretchable belt.
