Description

本発明は、膝、肘又は指等に装着し、蝶番関節の安定性を促進することによって、蝶番関節の靭帯或いは軟組織の損傷を防止するサポーターに関する。   The present invention relates to a supporter that is attached to a knee, elbow, finger, or the like and promotes the stability of the hinge joint to prevent damage to the ligament or soft tissue of the hinge joint.

従来、関節部の損傷防止、治療又は保温を目的とした膝又は肘用等のサポーターとしては、側副靭帯に沿って支持具を設けることにより関節部を固定して可動域を制限する構造や伸縮性のあるバンドで関節部の前後のぶれを固定して可動域を制限する構造等のサポーターが提供されている。   Conventionally, as a supporter for knees or elbows for the purpose of preventing damage to the joint, treating, or keeping warm, a structure in which the joint is fixed and a movable range is limited by providing a support along the collateral ligament. Supporters such as a structure that restricts the range of motion by fixing the front and back shake of the joint with an elastic band are provided.

しかしながら、関節部を固定して可動域を制限してしまうと、近位の関節及び筋組織に対して損傷等の悪影響を及ぼしてしまう可能性が高く、また、そのようなサポーターを持続的に使用することで筋力の低下を引き起こすという問題点があった。そんな中、以下のような関節部用のサポーターが提供されている。   However, if the joint portion is fixed and the range of motion is limited, there is a high possibility that the proximal joint and muscle tissue will be adversely affected, such as damage. There was a problem that using it caused a decrease in muscle strength. Meanwhile, the following supporters for joints are provided.

例えば、ほぼ筒状長手状のパイル編みであって、ほぼその中央において外側領域に足し糸をして編成した湾曲凸部を形成すると共に、該湾曲凸部と対向する内側領域においてフロートメッシュにて編成した非パイル領域とした湾曲凹部を形成することにより、屈伸部を除く他の領域では、サポーター本来の緊縛固定を有効に果たすと共に、肘又は膝等の屈伸部においては屈伸を容易にし、且つサポーター緊縛領域を有効に保温する肘又は膝用屈曲部サポーターが提供されている（特許文献１）。   For example, an approximately cylindrical longitudinal pile knitting, which forms a curved convex portion knitted by adding an additional thread to the outer region at the center, and a float mesh in the inner region facing the curved convex portion. By forming a curved recess as a knitted non-pile region, in other regions except the bending / extension portion, the supporter's original binding and fixation are effectively performed, and bending / extension at the bending / extension portion such as the elbow or knee is facilitated, and An elbow or knee flexion supporter that effectively keeps the supporter binding area warm is provided (Patent Document 1).

また、左右終端において結合すると共に本体において左右一対の帯状体として独立している二股状の弾性素材よりなるバンドを対称方向に一対備え、各バンドのそれぞれの帯状体を関節により結合されている靭帯の一対の部位に振り分けて装着し、各バンドを靭帯の一対の部位に対して互い違いに巻装することにより、各種の痛みや障害の原因である関節のねじれを、関節の屈曲運動を規制しないで防止する関節ねじれ防止サポーターが提供されている（特許文献２）。
特開平９−２８５５８７号公報 特開２００１−２９３７２号公報 In addition, a ligament comprising a pair of bifurcated elastic materials that are coupled at the left and right ends and independent as a pair of left and right strips in the main body in a symmetrical direction, and each band of each band is coupled by a joint. It is distributed and attached to a pair of parts, and each band is alternately wound around a pair of parts of the ligament, thereby preventing the twisting of the joint that causes various pains and disorders, and the bending movement of the joint is not regulated A joint torsion prevention supporter for preventing the above is provided (Patent Document 2).
Japanese Patent Laid-Open No. 9-285587 JP 2001-29372 A

ここで、関節部の伸屈運動について簡単に説明する。膝関節、指関節又は肘関節等のように基本的に屈曲及び伸展が主機能である蝶番関節において、各関節部の靭帯又は軟組織の損傷を防止し、関節運動の機能を向上させるためには、各関節部の安定性を保持する必要がある。   Here, the bending movement of the joint will be briefly described. In order to improve the function of joint movement by preventing damage to the ligaments or soft tissue of each joint part in hinge joints where bending and extension are basically the main functions such as knee joint, finger joint or elbow joint It is necessary to maintain the stability of each joint.

しかしながら、各関節機能には運動を行なうための機能的遊びが設けられていることから完全には嵌合していない。例えば、膝関節では（図７参照。）、（ａ）滑転しながらの屈曲、（ｂ）関節部中心を支点とする屈曲或いは（ｃ）関節部中心を支点としての滑転しながらの屈曲という各種の蝶番運動を行なうために、支点軸のぶれから関節部の安定性を阻害する場合が多々あり、また、肘関節では、前腕の回内外運動等により肘関節に捻れが生じて関節部の不安定性を誘発してしまう。   However, since each joint function is provided with functional play for exercise, it is not completely fitted. For example, in the knee joint (see FIG. 7), (a) bending while sliding, (b) bending with the joint center as a fulcrum, or (c) bending while sliding with the joint center as a fulcrum. In order to perform various types of hinge movements, the stability of the joint is often disturbed by the fulcrum of the fulcrum shaft. In the elbow joint, the elbow joint is twisted due to the pronation and external movement of the forearm, etc. Instability will be induced.

そこで、各関節部の靭帯又は軟組織の損傷を防止し、関節運動の機能を向上させるためには、各関節部にサポーター等の補助具を装着し、各関節部の伸屈運動における支点軸の安定性を保持させることで、各関節部の安定性を促進することが肝要となる。   Therefore, in order to prevent damage to the ligament or soft tissue of each joint part and improve the function of joint movement, an auxiliary tool such as a supporter is attached to each joint part, and the fulcrum shaft in the extension movement of each joint part. It is important to promote the stability of each joint by maintaining the stability.

しかしながら、特許文献１に記載の技術では、肘又は膝屈曲部の可動域は制限されていないものの、サポーター本来の緊縛固定を有効に果たしていることから、サポーター装着付近の体部には血液が滞留し、むくみの原因にもなってしまい、また、近位の関節及び筋組織に悪影響を及ぼす可能性が高い。さらに、肘又は膝屈曲部の伸屈運動における支点軸の安定性については考慮されておらず、肘又は膝屈曲部の安定性を保持することができないという問題点があった。   However, in the technique described in Patent Document 1, although the range of motion of the elbow or knee flexion part is not limited, blood is retained in the body part near the supporter's attachment because the supporter's original tight binding is effectively achieved. In addition, it may cause swelling, and is likely to adversely affect the proximal joint and muscle tissue. Furthermore, the stability of the fulcrum shaft in the bending motion of the elbow or knee flexion is not considered, and there is a problem that the stability of the elbow or knee flexion cannot be maintained.

また、特許文献２に記載の技術でも同様に、関節の屈曲運動における支点軸の安定性については考慮されていないことから、当該サポーターを装着したとしても、屈曲運動時の支点軸のぶれについては対応することができず、関節の安定性を保持することができないとともに、関節運動の機能を向上させることができないという問題点があった。   Similarly, the technique described in Patent Document 2 does not consider the stability of the fulcrum shaft in the bending motion of the joint. Therefore, even if the supporter is mounted, There is a problem that it is impossible to cope with it, it is impossible to maintain the stability of the joint, and the function of the joint movement cannot be improved.

上記課題を解決するために、本発明は次のように構成した。すなわち、本発明に係る蝶番関節の安定性促進サポーターは、伸縮性素材からなる筒状のサポーターであって、前記サポーターの左右両側面には、夫々Ｘ字状に対向して当接する第一の弓状弾性素材及び第二の弓状弾性素材を備え、左右両側面の強固な該当接点を結ぶラインに膝関節、肘関節又は指関節等の蝶番関節の伸屈における各関節部の支点軸を形成するとともに、各関節部の伸屈による前記支点軸のぶれに応じて前記左右両側面の第一の弓状弾性素材及び第二の弓状弾性素材の当接点が摺動することにより、前記支点軸の維持が可能となることを特徴とする。   In order to solve the above problems, the present invention is configured as follows. That is, the hinge joint stability promoting supporter according to the present invention is a cylindrical supporter made of a stretchable material, and the first and the left and right side surfaces of the supporter are in contact with each other in an X shape. It is equipped with an arched elastic material and a second arched elastic material, and the fulcrum axis of each joint part in the extension of the hinge joint such as the knee joint, elbow joint or finger joint is connected to the corresponding contact point on the left and right side surfaces. And the contact points of the first arched elastic material and the second arched elastic material on the left and right side surfaces slide according to the fulcrum of the fulcrum shaft due to the bending of each joint, The fulcrum shaft can be maintained.

本発明に係る膝、蝶番関節の安定性促進サポーターによれば、膝関節、肘関節又は指関節等の蝶番関節の安定性を促進することにより、蝶番関節の靭帯或いは軟組織の損傷を防止することが可能となるとともに、必要な関節部の可動域を制限せず、関節運動の支点軸を形成させることにより、関節運動の蝶番機能を向上させることが可能となる。   According to the knee and hinge joint stability promoting supporter according to the present invention, it is possible to prevent damage to the hinge joint ligament or soft tissue by promoting the stability of the hinge joint such as the knee joint, elbow joint or finger joint. In addition, it is possible to improve the hinge function of the joint motion by forming the fulcrum shaft of the joint motion without restricting the necessary range of motion of the joint portion.

以下、図面に基づいて本発明を具体的に説明する。図１は、本発明に係る蝶番関節の安定性促進サポーター１の右側面図であり、図２は、本発明に係る蝶番関節の安定性促進サポーター１の左側面図である。ここでは、膝用の蝶番関節の安定性促進サポーター１について説明する。本発明に係る蝶番関節の安定性促進サポーター１は、サポーター本体２、第一の弓状弾性素材３ａ及び３ｂ、第二の弓状弾性素材４ａ及び４ｂ並びに開口部５から構成される。   Hereinafter, the present invention will be specifically described with reference to the drawings. FIG. 1 is a right side view of a hinge joint stability promoting supporter 1 according to the present invention, and FIG. 2 is a left side view of the hinge joint stability promoting supporter 1 according to the present invention. Here, the stability promotion supporter 1 of the hinge joint for knees will be described. The hinge joint stability promoting supporter 1 according to the present invention includes a supporter body 2, first arcuate elastic materials 3 a and 3 b, second arcuate elastic materials 4 a and 4 b, and an opening 5.

図１は、上述の通り蝶番関節の安定性促進サポーター１の右側面図であって、サポーター本体２は、ナイロン又はポリエステル等を主とする伸縮性素材から構成されるが、当該素材に限定されるものではなく、伸縮性を有する編物又は織物の組織であればどのようなものであってもよい。また、通気性を重視するような場合であれば、伸縮性を有するメッシュ素材等を用いてもよい。   FIG. 1 is a right side view of the hinge joint stability promoting supporter 1 as described above, and the support body 2 is made of an elastic material mainly made of nylon or polyester, but is limited to the material. Any structure may be used as long as it has a stretchable knitted or woven structure. Further, if importance is placed on breathability, a stretchable mesh material or the like may be used.

第一の弓状弾性素材３ａは、ゴム、シリコン又はスポンジ素材等の弾性素材から構成されるが、当該素材に限定されるものではなく、弾性を有する素材であればどのようなものであってもよい。また、第一の弓状弾性素材３ａは、前記サポーター本体２の右側面に、前方向に開口するように湾曲した弓形状で形成され設けられている。   The first bow-shaped elastic material 3a is composed of an elastic material such as rubber, silicon or sponge material, but is not limited to the material, and any material having elasticity can be used. Also good. The first bow-shaped elastic material 3a is formed and provided on the right side surface of the supporter body 2 in a bow shape that is curved so as to open in the forward direction.

第二の弓状弾性素材４ａも同様に、ゴム、シリコン又はスポンジ素材等の弾性素材から構成されるが、当該素材に限定されるものではなく、弾性を有する素材であればどのようなものであってもよい。また、第二の弓状弾性素材４ａは、第一の弓状弾性素材３ａとは逆の後方向にく字状に湾曲して形成されるとともに、第一の弓状弾性素材３ａと互いに背を向けるようにＸ字状に当接し、前記サポーター本体２の右側面に設けられている。   Similarly, the second arcuate elastic material 4a is made of an elastic material such as rubber, silicon or sponge material, but is not limited to this material, and any material having elasticity can be used. There may be. Further, the second arcuate elastic material 4a is formed in a backward curved shape opposite to that of the first arcuate elastic material 3a, and is back-to-back with the first arcuate elastic material 3a. Is provided on the right side surface of the supporter body 2.

そして、Ｘ字状に当接している第一の弓状弾性素材３ａ及び第二の弓状弾性素材４ａの当接点６ａは、Ｘ字状の交点であることから強度が増すとともに、第一の弓状弾性素材３ａ及び第二の弓状弾性素材４ａは、当該当接点６ａにおいて固着されていないことから摺動可能に設けられており、膝関節の伸屈運動に応じて矢印Ａの方向に当接点６ａを連動させながら摺動する。   And since the contact point 6a of the 1st arched elastic material 3a and the 2nd arched elastic material 4a which are contact | abutting by X shape is an X-shaped intersection, strength increases and 1st The arcuate elastic material 3a and the second arcuate elastic material 4a are provided so as to be slidable because they are not fixed at the contact point 6a. Slide while interlocking the contact 6a.

開口部５は、膝蓋骨部分を露出させることにより、膝関節の伸屈運動を容易にするために設けるものである。膝蓋骨は、膝関節の伸屈運動に応じて大腿骨の下部表面を包み込むように滑動することから、開口部５を設けて蝶番関節の安定性促進サポーター１から膝蓋骨部分を露出させることにより、膝関節の伸屈運動における膝蓋骨の可動域を制限することなく、膝関節の伸屈運動が容易となる。   The opening 5 is provided for facilitating the knee joint stretching movement by exposing the patella portion. Since the patella slides so as to wrap around the lower surface of the femur according to the knee joint's flexion movement, the patella portion is exposed from the hinge joint stability promoting supporter 1 by providing the opening 5. The knee joint can be easily exercised without limiting the range of motion of the patella during the joint exercise.

図２は、上述の通り、本発明に係る蝶番関節の安定性促進サポーター１の左側面図であって、上述の図１で示した蝶番関節の安定性促進サポーター１の右側面と同様に、第一の弓状弾性素材３ｂ及び第二の弓状弾性素材４ｂがサポーター本体２の左側面に、夫々Ｘ字状に当接した状態で設けられている。   2 is a left side view of the hinge joint stability promoting supporter 1 according to the present invention, as described above. Similarly to the right side surface of the hinge joint stability promoting supporter 1 shown in FIG. A first arcuate elastic material 3b and a second arcuate elastic material 4b are provided on the left side surface of the supporter body 2 in a state of abutting in an X shape.

そして、同様にＸ字状に当接している第一の弓状弾性素材３ｂ及び第二の弓状弾性素材４ｂの当接点６ｂも、Ｘ字状の交点であることから強度が増すとともに、第一の弓状弾性素材３ｂ及び第二の弓状弾性素材４ｂは、当該当接点６ｂにおいて固着されていないことから、膝関節の伸屈運動に応じて矢印Ａの方向に当接点６ｂを連動させながら摺動する。   Similarly, the contact points 6b of the first bow-shaped elastic material 3b and the second bow-shaped elastic material 4b that are in contact with each other in the X-shape are also X-shaped intersection points. Since one arcuate elastic material 3b and the second arcuate elastic material 4b are not fixed at the contact point 6b, the contact point 6b is interlocked in the direction of the arrow A according to the knee joint's stretching movement. Slide while.

上記第一の弓状弾性素材３ａ及び３ｂは、第二の弓状弾性素材４ａ及び４ｂと比較して弓状弧が小さくなるように構成される。このように第一の弓状弾性素材３ａ及び３ｂの弓状弧を小さく構成して第二の弓状弾性素材４ａ及び４ｂよりも弾力性を持たせることにより、膝関節の屈曲状態からの伸展運動を促して容易にするとともに、第二の弓状弾性素材４ａ及び４ｂの弓状弧の方を大きく構成して弾力性を抑えることにより、当接点６ａ及び６ｂにおいて第一の弓状弾性素材３ａ及び第二の弓状弾性素材４ａ並びに第一の弓状弾性素材３ｂ及び４ｂが、夫々の圧接力で摺動時にずれることを防止することが可能となる。また、第一の弓状弾性素材３ａ及び３ｂの弾力性により、蝶番関節の安定性促進サポーターの装着者が跳躍又は着地等の運動をした際に、大腿骨が前に出ようとする力を抑えることで膝関節の損傷等を防止することが可能となる。   The first arcuate elastic materials 3a and 3b are configured such that the arcuate arc is smaller than the second arcuate elastic materials 4a and 4b. In this way, the arched arcs of the first arched elastic materials 3a and 3b are made smaller so as to be more elastic than the second arched elastic materials 4a and 4b, thereby extending the knee joint from the bent state. The first arcuate elastic material at the contact points 6a and 6b is facilitated by facilitating movement, and the arcuate arcs of the second arcuate elastic materials 4a and 4b are made larger to suppress elasticity. It is possible to prevent the 3a and second arcuate elastic material 4a and the first arcuate elastic material 3b and 4b from being displaced at the time of sliding by their respective pressure contact forces. In addition, due to the elasticity of the first arcuate elastic materials 3a and 3b, when the wearer of the hinge joint stability promoting supporter exercises jumping or landing, the force that the femur tries to come forward By suppressing it, it becomes possible to prevent damage to the knee joint and the like.

上述のように、Ｘ字状に当接している第一の弓状弾性素材３ａ及び第二の弓状弾性素材４ａ並びに第一の弓状弾性素材３ｂ及び第二の弓状弾性素材４ｂの夫々当接点６ａ及び当接点６ｂでは、Ｘ字状の交点であることにより強度が増すことから、当該当接点６ａ及び当接点６ｂを結ぶラインに支点軸７が形成される。そして、膝関節の伸屈運動に応じて当接点６ａ及び当接点６ｂが摺動するのに伴って、当接点６ａ及び当接点６ｂを結ぶ支点軸７も応動することから、支点軸７は維持され、膝関節の伸屈運動について安定性を促進することが可能となる。支点軸７については、図３乃至図６を用いて詳しく説明する。   As described above, the first arcuate elastic material 3a and the second arcuate elastic material 4a, the first arcuate elastic material 3b, and the second arcuate elastic material 4b are in contact with each other in an X shape. At the contact 6a and the contact point 6b, since the strength increases due to the X-shaped intersection, the fulcrum shaft 7 is formed on the line connecting the contact point 6a and the contact point 6b. As the abutment point 6a and the abutment point 6b slide according to the knee joint stretching movement, the fulcrum shaft 7 connecting the abutment point 6a and the abutment point 6b is also moved, so that the fulcrum shaft 7 is maintained. Thus, it becomes possible to promote the stability of the knee joint stretching movement. The fulcrum shaft 7 will be described in detail with reference to FIGS.

図３は、本発明に係る蝶番関節の安定性促進サポーターの正面図であり、図４は、その背面図である。上述の通り、前記当接点６ａ及び当接点６ｂが構成されることにより、破線で示した支点軸７が形成されている。なお、支点軸７は、より強度を有する当接点６ａ及び当接点６ｂを結ぶラインに不可視的に形成されるものである。   FIG. 3 is a front view of a hinge joint stability promoting supporter according to the present invention, and FIG. 4 is a rear view thereof. As described above, the fulcrum shaft 7 indicated by the broken line is formed by forming the contact point 6a and the contact point 6b. The fulcrum shaft 7 is formed invisible on a line connecting the contact points 6a and 6b having higher strength.

前記支点軸７が形成されることにより、膝関節では（図７参照。）、（ａ）滑転しながらの屈曲、（ｂ）関節部中心を支点とする屈曲或いは（ｃ）関節部中心を支点としての滑転しながらの屈曲という各種の蝶番運動を行なうために、支点軸７のブレから関節部の安定性を阻害するものの、当接点６ａ及び当接点６ｂを結ぶ支点軸７が、蝶番運動による当接点６ａ及び当接点６ｂの摺動に応動することにより支点軸７は維持され、関節運動の安定性を促進させることが可能となる。   By forming the fulcrum shaft 7 (see FIG. 7), (a) bending while sliding, (b) bending with the center of the joint as a fulcrum, or (c) center of the joint. In order to perform various hinge motions such as bending while sliding as a fulcrum, the fulcrum shaft 7 connecting the contact point 6a and the contact point 6b is hinged although the stability of the joint portion is hindered from the blurring of the fulcrum shaft 7. The fulcrum shaft 7 is maintained by responding to the sliding of the contact point 6a and the contact point 6b due to the motion, and the stability of the joint motion can be promoted.

図５は、本発明に係る蝶番関節の安定性促進サポーター１を膝の屈曲運動に合わせて湾曲させた状態を示す右側面図である。蝶番関節の安定性促進サポーター１は、膝が屈曲運動を行なうと当然に湾曲する。この時、第一の弓状弾性素材３ａは、膝の屈曲運動に伴って弓形状から棒状に伸び起き、且つ、第二の弓状弾性素材４ａは、膝の屈曲運動に伴ってより弓形状に湾曲することから、当接点６ａで固着されていない第一の弓状弾性素材３ａ及び第二の弓状弾性素材４ａが矢印Ａの方向に摺動し、それに伴って当該当接点６ａも矢印Ａの方向に連動する。   FIG. 5 is a right side view showing a state in which the stability promoting supporter 1 for the hinge joint according to the present invention is bent in accordance with the bending motion of the knee. The hinge joint stability supporter 1 naturally curves when the knee performs a flexion motion. At this time, the first arcuate elastic material 3a extends from a bow shape to a rod shape along with the knee bending motion, and the second arcuate elastic material 4a becomes more bow-shaped along with the knee flexing motion. Therefore, the first arcuate elastic material 3a and the second arcuate elastic material 4a that are not fixed at the contact point 6a slide in the direction of the arrow A, and the contact point 6a is also moved to the arrow. Interlocks with direction A.

上記図５による湾曲状態の説明は、蝶番関節の安定性促進サポーター１の右側面によるものであるが、左側面においても同様に、第一の弓状弾性素材３ｂ及び第二の弓状弾性素材４ｂの摺動並びに当該当接点６ｂの連動が生じる。これにより、右側面の当接点６ａ及び左側面の当接点６ｂを結ぶ支点軸７は、膝の屈曲運動によっても維持され、膝関節の蝶番運動の安定性を促進することが可能となる。   The description of the curved state according to FIG. 5 is based on the right side surface of the hinge joint stability promoting supporter 1, but the first arcuate elastic material 3b and the second arcuate elastic material are similarly applied to the left side surface. The sliding of 4b and the interlocking of the contact point 6b occur. As a result, the fulcrum shaft 7 connecting the contact point 6a on the right side surface and the contact point 6b on the left side surface is maintained by the knee bending motion, and the stability of the hinge motion of the knee joint can be promoted.

以上のように構成することで、本発明に係る蝶番関節の安定性促進サポーター１を装着すれば、膝関節等の蝶番関節の安定性を促進することにより、膝の蝶番関節の靭帯或いは軟組織の各種損傷を防止することが可能となるとともに、必要な関節部の可動域を制限せず、関節運動の支点軸７を形成させることにより、関節運動の機能を向上させることが可能となる。   With the configuration as described above, when the hinge joint stability promoting supporter 1 according to the present invention is mounted, the stability of the hinge joint such as the knee joint is promoted, so that the ligament or soft tissue of the knee hinge joint can be improved. Various types of damage can be prevented, and the function of joint motion can be improved by forming the fulcrum shaft 7 for joint motion without restricting the necessary range of motion of the joint portion.

図６は、本発明に係る蝶番関節の安定性促進サポーター１の使用状態を示す図であり、使用者の膝関節部分に装着されている。このように本願発明に係る蝶番関節の安定性促進サポーター１を膝関節部分に装着すれば、支点軸７が蝶番運動の安定性を促進させるとともに、膝関節の屈曲運動に伴う当接点６ａ及び当接点６ｂの摺動に応じて支点軸７が維持される。   FIG. 6 is a view showing a use state of the hinge joint stability promoting supporter 1 according to the present invention, which is attached to the knee joint portion of the user. As described above, when the hinge joint stability promoting supporter 1 according to the present invention is mounted on the knee joint, the fulcrum shaft 7 promotes the stability of the hinge movement, and the contact point 6a associated with the knee joint bending movement and the contact point 6a. The fulcrum shaft 7 is maintained according to the sliding of the contact 6b.

上記実施例では、膝用の蝶番関節の安定性促進サポーター１について説明したが、肘又は指等の蝶番関節においても本発明に係る蝶番関節の安定性促進サポーター１を使用してもよい。なお、肘関節又は指関節で使用する場合においては、上記実施例で説明した膝関節における膝蓋骨のような機能はないため、上記開口部５を設けずとも本発明に係る蝶番関節の安定性促進サポーターの機能を発揮させることは可能である。ただ、肘関節で使用する場合には、肘関節の屈曲時に尺骨が突出してしまうことから、上記開口部５を設けてもよい。   In the above-described embodiment, the hinge promoting stability supporter 1 for the knee hinge joint has been described. However, the hinge joint stability promoting supporter 1 according to the present invention may also be used for the hinge joint such as an elbow or a finger. When used in an elbow joint or a finger joint, since there is no function like the patella in the knee joint described in the above embodiment, the stability of the hinge joint according to the present invention is promoted without providing the opening 5. It is possible to exert the function of the supporter. However, when the elbow joint is used, since the ulna protrudes when the elbow joint is bent, the opening 5 may be provided.

本発明に係る蝶番関節の安定性促進サポーター１を肘関節又は指関節等の蝶番関節に装着すれば、夫々蝶番関節の安定性を促進することにより、肘又は指の蝶番関節の靭帯或いは軟組織の各種損傷を防止することが可能となるとともに、必要な関節部の可動域を制限せず、関節運動の支点軸７を形成させることにより、関節運動の機能を向上させることが可能となる。   When the hinge joint stability promoting supporter 1 according to the present invention is attached to a hinge joint such as an elbow joint or a finger joint, the stability of the hinge joint is promoted, so that the ligament or soft tissue of the hinge joint of the elbow or finger can be improved. Various types of damage can be prevented, and the function of joint motion can be improved by forming the fulcrum shaft 7 for joint motion without restricting the necessary range of motion of the joint portion.

上記実施例では、本発明に係る蝶番関節の安定性促進サポーター１は、蝶番関節において使用すると説明したが、肩の関節、手首や足首の関節又は腰の関節等においても関節部の安定性を促進させるという意図において使用することが可能であり、各関節部の各種損傷、或いは各種関節部の近位の筋肉又は軟組織の各種損傷を防止することができる。   In the above embodiment, it has been described that the hinge joint stability supporter 1 according to the present invention is used in a hinge joint. However, the stability of the joint portion is also improved in a shoulder joint, a wrist joint, an ankle joint, a waist joint, or the like. It can be used with the intention of promoting, and can prevent various damages of each joint part, or various damages of muscles or soft tissues proximal to each joint part.
