Description

【0001】
【発明の属する技術分野】
本発明は、肘用サポーターに関し、詳細には、登山、ハイキングやトレッキング時において、肘を曲げたり、曲げた状態を維持したり、また物を握りやすくできるように、腕や手首の筋肉を活性化させようとするものである。
【0002】
【従来の技術及びその課題】
従来公知の肘用サポーターは、特開平9−285587号に示すような形状をしており、保温を目的としたニット製品・ネオプレーン製品や、肘痛の予防として伸縮性のベルトを用いた商品が販売されている。しかし、こういったサポーターは保温・固定・障害予防・ケアを目的としたものであり、腕・手首などの運動性を高めることには何ら考慮されていない。
【0003】
また、ベルトを用いてテーピング効果を狙ったサポーターとしては、特開2001−25522号がある。この発明はよく考えられた発明ではあるが、肘に装着するときは片方の腕のみで行うか、あるいは他の人の助けを借りなければならず、装着が面倒であること、補助帯を装着すると違和感が生じるなどの問題点もあった。
【0004】
【発明が解決しようとする課題】
そこで、本発明は、保温・固定・障害予防・ケアだけでなく、肘に装着するだけで、ベルト等を用いなくても、腕・手首などの運動性を高めることができるサポーターを提供しようとするものである。
【0005】
【課題を解決するための手段】
ところで、筋緊張に関与する受容部は筋紡錘といい、筋紡錘は筋の内部に存在している。筋紡錘からの求心性繊維は脊髄の介在ニューロンを介して運動神経細胞の興奮を高め、それにより目的とする筋の緊張を促進させることがわかっている。
そのため、筋紡錘を含む筋組織を直接、圧迫刺激すると、運動神経細胞を興奮させ、運動能力を高めることが本件出願の発明者の研究により明らかになっている。
【0006】
請求項1の発明は、このような研究成果からなされたものであって、請求項1の発明に係る肘用サポーターは、着用者の腕の少なくとも肘関節上下を被覆する筒状のサポーター本体と、前記サポーター本体の一端の周囲に、略半周ずつ設けられた第1及び第2の伸縮阻害部と、他端の周囲表面に略半周ずつ設けられた第3及び第4の伸縮阻害部とを備え、前記第1の伸縮阻害部は上腕二頭筋を、第2の伸縮阻害部は上腕三頭筋を圧迫し、第3の伸縮阻害部は腕橈骨筋・長橈側手根伸筋・短橈側手根伸筋・尺側手根伸筋を圧迫し、第4の伸縮阻害部は橈側手根屈筋・尺側手根屈筋を圧迫し得るように、第1及び第2の伸縮阻害部と第3及び第4の伸縮阻害部とは、略90°ねじれの位置に配置されていることを特徴とする。
【0007】
請求項1の発明によれば、本発明肘用サポーター装着時には、サポーター本体の第1の伸縮阻害部は着用者の上腕部(肘上部)の上腕二頭筋を、第2の伸縮阻害部は上腕二頭筋の拮抗筋である上腕三頭筋を圧迫する。
すると、上腕二頭筋、上腕三頭筋内部の筋紡錘が興奮して、上腕二頭筋、上腕三頭筋の緊張が高まる。これにより筋の運動性が高まり肘関節を屈曲したり、曲げた状態を維持したりしやすくなる。
【0008】
また第3、第4の伸縮阻害部は、下腕部(肘下部)の腕橈骨筋、尺側手根屈筋と拮抗筋の尺側手根伸筋、橈側手根屈筋と拮抗筋の長(短)橈側手根伸筋を圧迫する。
すると、腕橈骨筋、尺側手根屈筋と拮抗筋の尺側手根伸筋、橈側手根屈筋と拮抗筋の長(短)橈側手根伸筋の筋紡錘が興奮して、腕橈骨筋、尺側手根屈筋と拮抗筋の尺側手根伸筋、橈側手根屈筋と拮抗筋の長(短)橈側手根伸筋の緊張が高まる。これにより筋の運動性が高まり手首の動きを安定させるので、力が入りやすくなり、物を握ることも容易になる。
以上の結果、本発明の肘用サポーターを使用すると、着用者の腕や手首の筋肉を活性化させることができるので、快適に登山、ハイキングやトレッキングを行うことが期待できる。
【0009】
第1乃至第4の伸縮阻害部は、樹脂またはラバーであることが好ましい。樹脂またはラバーとすることにより、着用者の腕の形状に柔軟に沿うことができる。また、前記第1乃至第4の伸縮阻害部が、樹脂またはラバーをプリントすることにより形成すれば、伸縮阻害部を形成すること自体も容易となる。
【0010】
本発明肘用サポーターは、第1及び第2の伸縮阻害部を有する端部の方を、第3及び第4の伸縮阻害部を有する端部よりも大径にする。
第1及び第2の伸縮阻害部は、肘より上(身体側)の上腕部を圧迫することを目的とし、また、第3及び第4の伸縮阻害部は、肘より下(手側)の下腕部を圧迫することを目的としている。
【0011】
通常、上腕部の方が下腕部よりも大径であるところから、上腕部に着用する第1及び第2の伸縮阻害部を有する端部の方を、下腕部に着用する第3及び第4の伸縮阻害部を有する端部よりも大径にしておけば、着用者の腕の形状に沿いやすくなる。
【0012】
本発明肘用サポーターは、第3の伸縮阻害部が全範囲に現れるように平面的に折り畳んだ際に、第1の伸縮阻害部側に屈曲するようにしておくと良い。
上腕部と下腕部とは、肘部において、上腕三頭筋側(第1の伸縮阻害部側)へやや屈曲しているのが自然な状態である。従って、本発明肘用サポーターを第1の伸縮阻害部側に最初から屈曲させておけば、着用者に違和感を与えることが少なくなる。
【0013】
【発明の実施の形態】
以下、本発明の実施態様を添付図面に基づいて説明する。
図1は本発明の一実施態様による肘用サポーターの正面図、図2(a)は図1の肘用サポーターの底面図(肘の外側から見た図)、図2(b)は図1の肘用サポーターの平面図(肘の内側から見た図)、図3は本発明の他の実施態様による肘用サポーターの正面図、図4(a)は図3の肘用サポーターの底面図(肘の外側から見た図)、図4(b)は図3の肘用サポーターの平面図(肘の内側から見た図)、図5(a)は右腕前側(肘の内側)の筋肉位置を示す説明図、図5(b)は右腕後側(肘の外側)の筋肉位置を示す説明図である。
【0014】
図1及び図2に示すように、肘用サポーター1は、着用者の腕の少なくとも肘関節上下を被覆する筒状のサポーター本体11と、筒状サポーター本体11の一端の周囲表面に、略半周ずつ設けられた第1の伸縮阻害部21と第2の伸縮阻害部22とを備えている。
また、他端の周囲表面にも、略半周ずつ第3の伸縮阻害部31と第4の伸縮阻害部32とを備えている。
そして、第1及び第2の伸縮阻害部21、22と第3及び第4の伸縮阻害部31、32とは、略90°ねじれの位置に配置されている。
なお、第1乃至第4の伸縮阻害部21、22、31、32は、筒状サポーター本体11の端部表面ではなく、裏面に設けることもできる。
【0015】
図5は腕(右腕)の筋肉位置を示す説明図である。
図5(a)は右腕前側(肘の内側)を示し、図5(b)は右腕後側(肘の外側)を示しており、51は上腕二頭筋、52は上腕三頭筋、53は腕橈骨筋、54は長橈側手根伸筋、55は短橈側手根伸筋、56は尺側手根伸筋、57は橈側手根屈筋、58は尺側手根屈筋である。
【0016】
第1の伸縮阻害部21は上腕二頭筋51を、第2の伸縮阻害部22は上腕三頭筋52を圧迫し、第3の伸縮阻害部31は腕橈骨筋53・長橈側手根伸筋54・短橈側手根伸筋55・尺側手根伸筋56を圧迫し、第4の伸縮阻害部32は橈側手根屈筋57・尺側手根屈筋58を圧迫するようにしている。
第1及び第2の伸縮阻害部21、22と第3及び第4の伸縮阻害部31、32とを略90°ねじれの位置に配置するのは、前記のように、各伸縮阻害部が最も効率よく目的の筋肉を圧迫することができるようにするためである。
【0017】
前記のように、筒状サポーター本体11の第1の伸縮阻害部21は着用者の上腕部(肘上部)の上腕二頭筋51を、第2の伸縮阻害部22は上腕二頭筋51の拮抗筋である上腕三頭筋52を圧迫するので、上腕二頭筋51、上腕三頭筋52内部の筋紡錘が興奮し、上腕二頭筋51、上腕三頭筋52の緊張が高まって、肘関節を屈曲したり、曲げた状態を維持したりしやすくなるものである。
【0018】
また、筒状サポーター本体11の第3、第4の伸縮阻害部31、32は、下腕部(肘下部)の腕橈骨筋53、尺側手根屈筋58と拮抗筋の尺側手根伸筋56、橈側手根屈筋57と拮抗筋の長(短)橈側手根伸筋54、55を圧迫するので、腕橈骨筋53、尺側手根屈筋58と拮抗筋の尺側手根伸筋56、橈側手根屈筋57と拮抗筋の長(短)橈側手根伸筋54、55の筋紡錘が興奮して、これらの筋肉の緊張が高まる。その結果、手首の動きを安定させることができ、力が入りやすくなり、物を握ることが容易になる。
【0019】
以上の結果として、本発明の肘用サポーター1を使用すると、肘関節を屈曲したり、曲げた状態を維持したりしやすくなるとともに、手首の動きを安定させることができ、力が入りやすくなり、物を握ることも容易になるので、着用者がより快適に登山、ハイキングやトレッキングを行うことを期待することができる。
【0020】
第1乃至第4の伸縮阻害部21、22、31、32は、樹脂またはラバーで構成されている。樹脂またはラバーであるので、着用者の腕の形状に柔軟に沿うことができる。
また、伸縮阻害部を樹脂またはラバーをプリントすることにより形成すれば、形成すること自体も容易となる。
【0021】
第1乃至第4の伸縮阻害部21、22、31、32の端部は、図1及び図2に示すようにL字状にしておくと良い。
具体的に図1の第3伸縮阻害部31を例に取ると、その端部311、312をL字状としておくものである。このような構成すれば、丁度それぞれの筋肉を第3伸縮阻害部の両端からつまむように締め付ける形になるので、有効に筋肉を刺激することができる。
【0022】
第1及び第2の伸縮阻害部21、22を有する端部の方を、第3及び第4の伸縮阻害部31、32を有する端部よりも大径にしている。人体の上腕部は下腕部よりも大径であるところから、前記構成にすることで、着用者の腕の形状に沿いやすくできる。
【0023】
図示はしないが、図1及び図2の実施例において、上腕部に着用する第1及び第2の伸縮阻害部21、22を有する端部と、下腕部に着用する第3及び第4の伸縮阻害部31、32を有する端部とを略同径にすることもできる。この場合は、どちらが上腕部側(すなわち、第1及び第2の伸縮阻害部21、22側)かを示す目印を入れておくと着用方向の間違いがなくなる。
【0024】
図1に示すように、筒状サポーター本体11を、第3の伸縮阻害部31が全範囲に現れるように平面的に折り畳んだ際に、第1の伸縮阻害部21側に屈曲した形状となるようにしておけば、腕の自然な形状に沿い、着用者に違和感を与えることが少なくなる。
図1及び図2の実施例では、筒状サポーター本体11の肘内側部41と肘裏側部42を、筒状サポーター本体11とは異なる編み方とすることにより、筒状サポーター本体11が第1の伸縮阻害部21側に屈曲した形状となるようにしている。
【0025】
図3及び図4は、本発明の他の実施態様による肘用サポーターを示すものであり、図1及び図2の実施態様と同じ機能を果たす部位には同じ符号を付している。
図1及び図2の実施態様と図3及び図4の実施態様とが異なる点は、前者の第1乃至第4の伸縮阻害部21、22、31、32の端部は、筒状サポーター本体11の筒状長手方向に対し切断された空間12を有していることである。これは、前記したように、伸縮阻害部の端部を(例えば、311、312のように)L字状として、それぞれの筋肉を両端からつまむように締め付ける形にしたので、空間12としておくと、前記機能をよりよく発揮させることができるからである。
【0026】
一方、図3及び図4の実施態様では、第1乃至第4の伸縮阻害部21、22、31、32の短辺の端部は、それぞれ重なって存在するようにしている。
これは、筋肉を直接圧迫する中央寄り部分は、対象となる筋群を効果的に圧迫することができるように幅広な伸縮阻害部とし、筋肉を直接圧迫しない端部は、適度な伸縮性を持たせて腕を締めすぎないようにするためである。
【0027】
さらに、図3及び図4の実施態様では、第1及び第2伸縮阻害部21、22の配置の仕方と、第3及び第4伸縮阻害部31、32の配置の仕方を変えている。これは、下腕部においては、圧迫する筋群がほぼ同じ位置に位置しているため、第3及び第4伸縮阻害部31、32を左右対称としているものである。
一方、上腕部においては、肘関節を屈曲した際に、上腕二等筋51の***部がやや上寄り(身体側)にできるため、第1の伸縮阻害部21も上腕二等筋51を圧迫しやすいように筒状サポーター本体11の筒状端部のより端部側に配し、第2の伸縮阻害部22は筒状端部の内側に配置しているものである。
その他は、図1及び図2の実施例と、図3及び図4の実施例とで変わるところがない。
【0028】
【発明の効果】
以上のように、本発明に係る肘用サポーター1によれば、筒状サポーター本体11の第1の伸縮阻害部21は着用者の上腕部(肘上部)の上腕二頭筋51を、第2の伸縮阻害部22は上腕二頭筋51の拮抗筋である上腕三頭筋52を圧迫するので、前記筋肉の筋紡錘が興奮し、緊張が高まる結果、肘関節を屈曲したり、曲げた状態を維持したりしやすくなる。
【0029】
また、筒状サポーター本体11の第3、第4の伸縮阻害部31、32は、下腕部(肘下部)の腕橈骨筋53、尺側手根屈筋58と拮抗筋の尺側手根伸筋56、橈側手根屈筋57と拮抗筋の長(短)橈側手根伸筋54、55を圧迫するので、前記筋肉の筋紡錘が興奮して、これらの筋肉の緊張が高まる結果、手首の動きを安定させることができ、力が入りやすくなり、物を握ることが容易になる。
以上の結果、着用者の登山、ハイキングやトレッキング時の腕や手首の筋肉を活性化することが可能となるので、使用者が快適に登山、ハイキングやトレッキングを行うことが期待できる。

BACKGROUND OF THE INVENTION
The present invention relates to an elbow supporter, and in particular, when climbing, hiking or trekking, the arm and wrist muscles are activated so that the elbow can be bent, maintained in a bent state, and easily grasped. I want to make it.
[0002]
[Prior art and problems]
Conventionally known elbow supporters have a shape as shown in Japanese Patent Application Laid-Open No. 9-285589, and there are knit products and neoprene products for keeping warm, and products using elastic belts for prevention of elbow pain. Sold. However, these supporters are intended for heat insulation, fixation, prevention of disability, and care, and are not considered at all to improve the mobility of arms and wrists.
[0003]
Japanese Patent Application Laid-Open No. 2001-25522 discloses a supporter that uses a belt and aims at a taping effect. This invention is a well-thought-out invention, but when worn on the elbow, it must be done with only one arm or with the help of another person. Then, there was a problem such as uncomfortable feeling.
[0004]
[Problems to be solved by the invention]
Therefore, the present invention aims to provide a supporter that can enhance the mobility of arms and wrists without using a belt or the like by simply wearing it on the elbow, as well as keeping warm, fixing, preventing obstacles and taking care. To do.
[0005]
[Means for Solving the Problems]
By the way, the receiving part involved in muscle tone is called a muscle spindle, and the muscle spindle exists inside the muscle. Centripetal fibers from muscle spindles have been shown to enhance motor neuron excitability via spinal interneurons, thereby promoting targeted muscle tone.
Therefore, it has been clarified by the research of the inventors of the present application that when the muscle tissue including the muscle spindle is directly compressed and stimulated, the motor neurons are excited and the exercise ability is enhanced.
[0006]
The invention of claim 1 is based on such research results, and the elbow supporter according to the invention of claim 1 includes a cylindrical supporter body that covers at least the upper and lower elbow joints of a wearer's arm. The first and second expansion / contraction inhibition portions provided approximately half a circumference around one end of the supporter body, and the third and fourth expansion inhibition portions provided approximately half a circumference around the other end of the support body. The first stretch inhibiting part presses on the biceps, the second stretch inhibiting part presses on the triceps, and the third stretch inhibiting part acts on the brachial peroneal muscle, the longus lateral carpal extensor and the short The first and second extension / contraction inhibitory sections so as to compress the heel side carpal extensor and the ulnar carpal extensor, and the fourth expansion / contraction inhibition section can compress the heel side carpal flexion / ulnar carpal flexor; The third and fourth expansion / contraction inhibiting portions are characterized by being arranged at a position of approximately 90 ° twist.
[0007]
According to the first aspect of the present invention, when the elbow supporter of the present invention is mounted, the first stretch inhibiting part of the supporter body is the biceps brachii of the wearer's upper arm (upper elbow), and the second stretch inhibiting part is Compress the triceps, which is an antagonist of the biceps.
Then, the muscle spindles inside the biceps and triceps are excited and the tension of the biceps and triceps increases. This increases the mobility of the muscles and makes it easier to bend the elbow joint and maintain the bent state.
[0008]
In addition, the third and fourth expansion / contraction-inhibiting portions are the brachial muscles of the lower arm (lower elbow), the ulnar carpal flexors and antagonist muscles of the ulnar carpal extensors, the radial carpal flexors and antagonist muscles ( (Short) Press the radial carpal extensor.
Then, the ulnar carpal muscle, the ulnar carpal flexor and antagonist muscle ulnar carpal extensor muscle, the heel side carpal flexor and antagonist muscle length (short), the radial spindle muscle muscle spindle excited, The tension of the ulnar carpal flexor and antagonist muscle, the ulnar carpal flexor and antagonist long (short) heel side carpal muscle increases. This increases muscle motility and stabilizes wrist movement, making it easier to apply force and gripping objects.
As a result, when the elbow supporter of the present invention is used, the muscles of the wearer's arm and wrist can be activated, so that it can be expected that mountain climbing, hiking and trekking are performed comfortably.
[0009]
It is preferable that the 1st thru | or 4th expansion-contraction inhibition part is resin or rubber. By using resin or rubber, it is possible to flexibly follow the shape of the wearer's arm. In addition, if the first to fourth expansion / contraction inhibition portions are formed by printing a resin or rubber, it is easy to form the expansion / contraction inhibition portion itself.
[0010]
The elbow supporter of the present invention has a larger diameter at the end portion having the first and second expansion / contraction inhibition portions than at the end portion having the third and fourth expansion / contraction inhibition portions.
The first and second expansion / contraction inhibition portions aim to compress the upper arm portion above the elbow (body side), and the third and fourth expansion inhibition portions are below the elbow (hand side). The purpose is to compress the lower arm.
[0011]
Usually, since the upper arm part has a larger diameter than the lower arm part, the end part having the first and second expansion and contraction inhibiting parts worn on the upper arm part is worn on the lower arm part. If it is made larger than the end part which has a 4th expansion-contraction inhibition part, it will become easy to follow a wearer's arm shape.
[0012]
The elbow supporter of the present invention may be bent toward the first expansion / contraction inhibition part when folded in a plane so that the third expansion / contraction inhibition part appears in the entire range.
It is natural that the upper arm part and the lower arm part are bent slightly toward the triceps side (first stretch inhibition part side) in the elbow part. Therefore, if the elbow supporter of the present invention is bent from the beginning toward the first expansion / contraction inhibition side, the wearer is less likely to feel uncomfortable.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
1 is a front view of an elbow supporter according to an embodiment of the present invention, FIG. 2A is a bottom view of the elbow supporter of FIG. 1 (viewed from the outside of the elbow), and FIG. 3 is a plan view of the elbow supporter (viewed from the inside of the elbow), FIG. 3 is a front view of the elbow supporter according to another embodiment of the present invention, and FIG. 4A is a bottom view of the elbow supporter of FIG. Fig. 4 (b) is a plan view of the elbow supporter in Fig. 3 (view from the inside of the elbow), and Fig. 5 (a) is the muscle on the front side of the right arm (inside the elbow). FIG. 5B is an explanatory diagram showing the muscle position on the rear side of the right arm (outside the elbow).
[0014]
As shown in FIG. 1 and FIG. 2, the elbow supporter 1 has a cylindrical supporter body 11 covering at least the upper and lower elbow joints of the wearer's arm, and a substantially half circumference on the peripheral surface of one end of the cylindrical supporter body 11. A first expansion / contraction inhibition portion 21 and a second expansion / contraction inhibition portion 22 are provided.
Also, the peripheral surface at the other end is provided with the third expansion / contraction inhibition part 31 and the fourth expansion / contraction inhibition part 32 approximately every half circumference.
And the 1st and 2nd expansion / contraction inhibition parts 21 and 22 and the 3rd and 4th expansion / contraction inhibition parts 31 and 32 are arrange | positioned in the position of about 90 degree twist.
In addition, the 1st thru | or 4th expansion-contraction inhibition part 21,22,31,32 can also be provided in the back surface instead of the edge part surface of the cylindrical supporter main body 11. FIG.
[0015]
FIG. 5 is an explanatory diagram showing the muscle position of the arm (right arm).
5A shows the front side of the right arm (inner side of the elbow), FIG. 5B shows the rear side of the right arm (outside of the elbow), 51 is biceps, 52 is triceps, 53 Is the brachial carpal muscle, 54 is the long carpal side extensor, 55 is the short carpal side extensor, 56 is the ulnar carpal extensor, 57 is the calcaneal carpal flexor, and 58 is the ulnar carpal flexor.
[0016]
The first stretch inhibition unit 21 presses the biceps 51, the second stretch inhibition unit 22 presses the triceps 52, and the third stretch inhibition unit 31 stretches the brachial muscle 53 and the long palmar side. The muscle 54, the short palmar side extensor muscle 55, and the ulnar carpal extensor muscle 56 are pressed, and the fourth expansion / contraction inhibitor 32 compresses the heel side carpal flexor 57 and the ulnar carpal flexor 58.
As described above, the first and second expansion / contraction inhibition portions 21 and 22 and the third and fourth expansion / contraction inhibition portions 31 and 32 are arranged at a position of approximately 90 ° twist as described above. This is because the target muscle can be efficiently compressed.
[0017]
As described above, the first stretch inhibiting part 21 of the cylindrical supporter body 11 is the biceps 51 of the upper arm part (upper elbow) of the wearer, and the second stretch inhibiting part 22 is the biceps 51 of the wearer. Since the triceps surae 52, which is an antagonistic muscle, is compressed, the muscle spindles inside the biceps 51 and triceps 52 are excited, and the tension of the biceps 51 and triceps 52 increases. It is easy to bend the elbow joint and maintain the bent state.
[0018]
The third and fourth expansion / contraction inhibition portions 31 and 32 of the cylindrical supporter main body 11 are the brachial muscle 53, the ulnar carpal flexor muscle 58 of the lower arm (lower elbow), and the ulnar carpal extension of the antagonist muscle. Since the muscle 56, the heel side carpal flexor 57 and the long (short) heel side carpal extensor muscles 54, 55 are pressed, the brachial muscle 53, the ulnar carpal flexor 58 and the antagonist muscle ulnar carpal extensor 56, the muscle spindles of the heel side carpal flexor muscle 57 and the long (short) heel side carpal extensor muscles 54, 55 of the antagonist muscles are excited, and the tension of these muscles increases. As a result, the movement of the wrist can be stabilized, the force can be easily applied, and the object can be grasped easily.
[0019]
As a result of the above, when the elbow supporter 1 of the present invention is used, the elbow joint can be easily bent and maintained in a bent state, the wrist movement can be stabilized, and force can be easily applied. Since it also becomes easier to hold objects, it can be expected that the wearer will more comfortably climb, hike and trekk.
[0020]
The 1st thru | or 4th expansion-contraction inhibition part 21,22,31,32 is comprised by resin or rubber. Since it is resin or rubber, it can flexibly follow the shape of the wearer's arm.
Moreover, if the expansion / contraction inhibition part is formed by printing a resin or rubber, the formation itself becomes easy.
[0021]
The end portions of the first to fourth expansion / contraction inhibition portions 21, 22, 31, and 32 are preferably L-shaped as shown in FIGS.
If the 3rd expansion-contraction inhibition part 31 of FIG. 1 is specifically taken as an example, the edge parts 311 and 312 will be made into L shape. With such a configuration, each muscle is tightened so as to be pinched from both ends of the third expansion / contraction inhibiting portion, so that the muscle can be stimulated effectively.
[0022]
The end portions having the first and second expansion / contraction inhibition portions 21 and 22 have a larger diameter than the end portions having the third and fourth expansion / contraction inhibition portions 31 and 32. Since the upper arm portion of the human body has a larger diameter than the lower arm portion, the above configuration facilitates conforming to the shape of the wearer's arm.
[0023]
Although not shown, in the embodiment of FIGS. 1 and 2, the end portion having the first and second expansion inhibition portions 21 and 22 worn on the upper arm portion, and the third and fourth portions worn on the lower arm portion. The end portions having the expansion / contraction inhibition portions 31 and 32 can be made substantially the same diameter. In this case, if a mark indicating which is the upper arm portion side (that is, the first and second expansion / contraction inhibition portions 21 and 22 side) is put, an error in the wearing direction is eliminated.
[0024]
As shown in FIG. 1, when the cylindrical supporter body 11 is folded in a plane so that the third expansion / contraction inhibition part 31 appears in the entire range, the cylindrical supporter body 11 is bent to the first expansion / contraction inhibition part 21 side. By doing so, the wearer is less likely to feel uncomfortable along the natural shape of the arm.
In the embodiment of FIGS. 1 and 2, the tubular supporter body 11 is the first by making the elbow inner side portion 41 and the elbow back side portion 42 of the tubular supporter body 11 different from the tubular supporter body 11. It is made to become the shape bent to the expansion-contraction inhibition part 21 side.
[0025]
FIGS. 3 and 4 show an elbow support according to another embodiment of the present invention, and parts having the same functions as those of the embodiment of FIGS. 1 and 2 are denoted by the same reference numerals.
The embodiment shown in FIGS. 1 and 2 is different from the embodiment shown in FIGS. 3 and 4 in that the ends of the former first to fourth expansion inhibiting portions 21, 22, 31, and 32 are cylindrical supporter bodies. 11 having a space 12 cut with respect to the cylindrical longitudinal direction. As described above, the end portion of the expansion / contraction inhibiting portion is L-shaped (for example, 311 and 312) and is tightened so that each muscle is pinched from both ends. This is because the above functions can be exhibited better.
[0026]
On the other hand, in the embodiment of FIG. 3 and FIG. 4, the end portions of the short sides of the first to fourth expansion / contraction inhibition portions 21, 22, 31, 32 are overlapped with each other.
This is because the central part that directly compresses the muscle is a wide stretch inhibiting part so that the target muscle group can be effectively compressed, and the end part that does not directly press the muscle has moderate elasticity. This is to prevent them from tightening their arms too much.
[0027]
Further, in the embodiment of FIGS. 3 and 4, the arrangement of the first and second expansion inhibition units 21 and 22 and the arrangement of the third and fourth expansion inhibition units 31 and 32 are changed. In the lower arm portion, the muscle groups to be compressed are located at substantially the same position, and therefore the third and fourth expansion / contraction inhibition portions 31 and 32 are symmetric.
On the other hand, in the upper arm, when the elbow joint is bent, the raised portion of the upper arm bilateral muscle 51 can be slightly upward (on the body side). In order to facilitate, the second support member 22 is disposed on the inner side of the cylindrical end portion, with the second support portion 22 being disposed on the inner end side of the cylindrical end portion of the cylindrical supporter body 11.
Other than that, there is no difference between the embodiment of FIGS. 1 and 2 and the embodiment of FIGS.
[0028]
【The invention's effect】
As described above, according to the elbow supporter 1 according to the present invention, the first expansion / contraction inhibition part 21 of the cylindrical supporter main body 11 is the second biceps muscle 51 of the wearer's upper arm (upper elbow). Since the muscular spindle of the muscle excites and increases tension, the expansion / contraction inhibition part 22 of the arm presses the triceps brachi 52, which is an antagonist of the biceps 51, and the elbow joint is bent or bent. It becomes easy to maintain.
[0029]
The third and fourth expansion / contraction inhibition portions 31 and 32 of the cylindrical supporter main body 11 are the brachial muscle 53, the ulnar carpal flexor muscle 58 of the lower arm (lower elbow), and the ulnar carpal extension of the antagonist muscle. Since the muscle 56, the heel side carpal flexor 57 and the antagonistic muscle long (short) heel side carpal extensor muscles 54, 55 are compressed, the muscle spindles of the muscles are excited and the tension of these muscles increases, The movement can be stabilized, the force can be easily applied, and the object can be grasped easily.
As a result, it becomes possible to activate the muscles of the arms and wrists during the climbing, hiking and trekking of the wearer, and it is expected that the user can comfortably climb, hiking and trekking.
