Description

  The present invention relates to a supporter that is mounted around a joint serving as a fulcrum for a bending motion such as a knee or an elbow.

  A large number of knee supporters have been provided as this type of supporter. For example, in the supporter 1 shown in FIG. 12 disclosed in Japanese Patent Laid-Open No. 7-265354, side bones 2 are disposed at positions along the bending lines on the left and right sides of the knee joint. It is said to act to assist and reduce the burden on the knee.

  Usually, knee pain is mainly caused by the bone and bone colliding because the cartilage is worn down and the quadriceps and ligaments that control the knee joint are weakened due to aging and lack of exercise, etc. It is the cause. However, although the side bone 2 as described above has an effect of preventing the position shift of the supporter, the effect of actually relieving the collision between the bones of the knee joint and the bone is very weak, and the function as a knee supporter is not effective. It is enough.

  Further, in Japanese Patent Application Laid-Open No. 2000-232992, as shown in FIG. 13, a splint 7 and a cushion material 8 that press the knee joint are attached to positions corresponding to the left and right sides of the knee joint, and a band wound around the outer periphery of the supporter body 6 The supporter 5 provided with 9 is proposed. This supporter 5 is said to be able to firmly fix the joint surface by tightening around the knee with a band 9, and to reduce the burden on the knee by being able to press and fix the splint 7 and the cushion material 8 more strongly. .

  However, the supporter 5 has a structure in which the entire knee circumference is firmly tightened at all times. Therefore, there is a problem in that the movement of the knee is restricted and the pressure on the back of the knee is particularly strong when the knee is bent. Further, the burden on the knee becomes larger when the knee is bent than when standing upright, but the strengthening of the support force at the time of knee flexion is not considered.

JP-A-7-265354 JP 2000-2322992 A

The present invention has been made in view of the above problems, and the knee supporter does not always strongly tighten the entire circumference of the knee, but exerts a strong support force especially at the time of knee flexion, which increases the burden on the knee. The aim is to provide a knee supporter that can relieve the collision between the bones of the joints.
Furthermore, as with the knee joint, a supporter that can exert a strong support force so as not to cause inadvertent torsional rotation at joints such as elbows, ankles, and wrists that serve as fulcrums during bending operations. It is an issue to provide.

In order to solve the above problems, the present invention provides:
A supporter that is attached to a joint that becomes a fulcrum during bending movement,
A tubular or wrap-type body is mounted around the joint, the pocket is provided at a position corresponding to the left and right sides of the joint, formed by the flowable material within the pocket by filling the bag body Pressurizing material is inserted ,
The left and right pockets extend in the vertical direction as an outwardly curved arc shape, a “<” shape, or a crescent shape, and the pressurizing material is shaped along the shape of the pocket. An opening for insertion of the pressure material is provided at the upper end of the pocket, and a slit in the width direction is provided at the center in the vertical direction of the pocket,
To generate variation in the internal pressure the said flowable material and pressurized圧材is deformed to flow in response to the bending and stretching operation of the joint, support force by increasing the pressure of the right and left sides of the joint during flexion A supporter is provided that is characterized in that the configuration is enhanced.

  The supporter according to the present invention having the above-described structure is characterized in that the means for generating the support force is not a conventionally used elastic pad or bone, but a pressure material in which a bag is filled with a fluid substance. By using a fluid substance, the fluid substance flows in response to bending and stretching operations, causing pressure fluctuations inside the pressurized material, and when bending the joint, the pressure at the location where the support force is to be increased increases, When stretched, the pressure becomes substantially equal and does not apply an excessive load.

Specifically, the supporter according to the present invention stabilizes the joint bone by supporting the bone from the side with the pressurizing material to prevent the joint from shifting in the left-right direction, and also pressurizes the joint left and right collateral ligaments to support the bone. And can prevent bone collision. Further, the applied pressure (support force) is increased by the repulsive force of the fluid material inside because the pressure body bag body is also deformed and compressed when bent from the state where the joint is extended. Therefore, it is possible to relieve discomfort and difficulty of movement compared to conventional supporters that always tighten around the joint strongly, and at the time of bending the joint, it can exert a large support force and can greatly reduce the burden on the knee. .
On the other hand, in a state where the joint is extended, the pressurizing material returns to the original state, and an appropriate uniform compression force can be applied to both sides of the joint.
And since the pressure is loaded rather than a fluid substance, since the skin contact is good and fit property is high, the uncomfortable feeling at the time of wearing can be eased.

Pockets for inserting the pressure圧材is, as described above, are provided on left and right sides, further provided on the upper side and the lower side surrounding the joints, U-shaped, inverted U-shaped, even more provided annularly Good.

The bag of the pressurizing material is made of a flexible resin, and is filled with air, a gel-like substance or fine powder as a fluid substance.
Examples of the gel substance include gel bodies, and examples of the fine powder include powder beads.
Such a pressurizing material filled with air or a gel-like substance has moderate shape stability and deformability, so that it follows the joint movement and surface shape when bent and stretched. It changes into a shape and can be brought into close contact with the knee without a sense of incongruity and efficiently exert a pressure assist function.

Among these, from the viewpoint of ease of handling, cost, and light weight, air is most preferably used as the fluid substance, and the pressurizing material is preferably a so-called airbag.
The bag body may have a hermetically sealed structure, and the airbag may be disposable, and replaced with an airbag whose air pressure has been changed. That is, it is preferable to prepare as an option a pressurizing material in which the air pressure is changed .

The supporter is mounted in the Takashi Seki for sweat is likely to penetration, it is washing at a suitable period.
Therefore, as damage to the pressurized圧材during washing it does not occur, and configured to insert the pressurized圧材detachably pocket. In addition, repair and exchange at failure of the pressurized圧材, instead of taken a different pressure圧材of pressure, removable hard adjustment of the pressure圧材in accordance with the taste and symptoms than possible points, pressurized圧材in pocket It is free . It is as insertion slot opened the upper end of the pocket. Et al., Is provided in the width direction of the slit in the central portion in the longitudinal direction of.

The cylindrical or wound type main body is made of an elastic resin material whose surface is covered with a cloth, and the elastic resin material has a bulge portion and / or a hollow portion formed according to the shape of the joint. Is preferred.
As described above, when the main body is molded with an elastic resin material such as urethane and the surface is covered with fibers, an appropriate load can be applied without giving the joint a feeling of tightening, and bending and stretching can be performed. A feeling of wearing can be raised without inhibiting a behavior.
In addition, when the elastic resin material is used, the bulging portion and / or the depression portion corresponding to the shape of the joint can be easily formed. Thus, by making it the shape corresponding to the shape of a joint, while being able to prevent a supporter's shift | offset | difference, the discomfort at the time of wear can be reduced more.

  The use of the supporter of the present invention is not limited as long as the supporter is attached to a joint serving as a fulcrum during a bending operation such as a knee, elbow, ankle, and / or wrist.

In the case of a knee supporter, the main body is a cylindrical type or a wound type that is worn around the knee joint, and a circular hole is punched through a portion corresponding to the kneecap of the main body,
A back material made of a separate elastic resin material is provided on the inner surface of the main body, and a knee pad portion bulging into the through hole is provided on the separate elastic resin material, and both the left and right sides of the knee pad portion The pocket is formed by the part and the main body, and the pressurizing material can be detachably inserted into the pocket,
It is preferable that the pressure member is compressed when the knee is bent rather than standing upright to increase the pressure in the pressure member, and the support force to the left or right side or both sides of the knee joint is enhanced.

In the knee supporter having the above-described configuration, the pressurizing material supports and stabilizes the patella from the side, can prevent the lateral displacement of the knee joint, and pressurizes the left and right collateral ligaments of the knee joint to assist the bone and bone. Can prevent collisions. Further, the applied pressure (support force) is increased by the repulsive force of the fluid substance due to the pressure material being compressed when the knee is bent when the burden on the knee is greater than when standing upright. Therefore, it is possible to relieve discomfort and painful movement as compared with the conventional supporter that always strongly tightens the circumference of the knee, and it is possible to greatly reduce the burden on the knee by exerting a large support force at the time of knee flexion.
In addition, since the filler in the pressurizing material is a fluid substance, it can flow according to the knee flexion or upright, and can always apply an appropriate compression force to both sides of the knee, and has good skin contact. Because it has high fit, it can alleviate the feeling of strangeness when worn.
Furthermore, since a circular punched hole is provided in the main body at a portion corresponding to the kneecap, and a bulging back surface material covering the kneecap is provided in the punched hole, the supporter can be prevented from being displaced.
In addition, the body of the knee supporter may be either a cylindrical type or a wound type, and in the case of the wound type, the joining position of the winding end may be on either the front side or the back side of the knee, It is preferable to use the back of the knee.

Further, in the knee supporter, the portion corresponding to the kneecap of the main body is bulged in a circular shape, or a circular hole is punched through the portion corresponding to the kneecap of the main body, or
A circular hole is perforated in a portion corresponding to the kneecap of the main body, a surface material made of a separate elastic resin material is stacked, a circular bulge is provided on the surface material, and the surface material is The pockets may be provided extending laterally.

As described above, when the main body corresponding to the kneecap is bulged so that the kneecap is just fitted, the supporter can be prevented from being displaced.
Also, if a hole is made in the part corresponding to the kneecap, heat can be released and released from the hole, and in particular, the discomfort caused by sweat and heat in summer can be eliminated, and the kneecap can be freely moved and has excellent exercise tracking. Become.
Furthermore, as mentioned above, the body is pierced with the kneecap, and when the swelled surface material is stacked, sweating properties can be maintained, and the displacement function is excellent, and pockets are also formed with the surface material. Then, a multi-function can be provided with a simple configuration.

Further, in the knee supporter, it is preferable that an opening is provided at the knee joint bending position of the back of the knee.
The opening on the back of the knee can eliminate wrinkles caused by folding of the supporter fabric on the back of the knee when flexing the knee, and can ease the feeling of pressure on the back of the knee, making exercise such as walking and knee flexion uncomfortable. As well as being able to do it easily, it can also prevent misalignment of the supporter. Further, heat can be released and moisture can be released from the opening, and discomfort caused by sweat and heat in summer can be eliminated.

  The bulge or opening of the kneecap and the opening of the back of the knee are not limited to the knee supporter. In the elbow supporter, the portion corresponding to the elbow is bulged, or an opening is provided. It is preferable to provide an opening.

Furthermore, it is good also as a structure provided with the side bone in the position which hits the both right and left sides of a knee joint on the outer side from the said right and left pressurization material.
Since the side bone is attached at a location with high bending resistance, the side bone can be prevented from being bent toward the back side of the knee, which can be bent greatly, and the displacement of the supporter can be reliably prevented.
In addition, it is preferable that the said side bone attaches the arcuate thing curved in the opposite direction to the knee bending direction. Thereby, the bending resistance to a knee bending direction can be improved further.

And it is good also as an ankle support part and serving as support of an Achilles tendon. In this case, the leg part from the ankle to the knee is also covered with the main body made of the elastic resin material and the pressure is appropriately applied, so that the leg can be provided with a function of making the leg thinner.
Furthermore, the supporter of the present invention may be made of a waterproof (water repellent) material so that it can be used underwater.

  As described above, in the joint supporter of the present invention, since the pressurizing material in which the bag body is filled with a fluid substance such as air is used, when the bag body is deformed and compressed when the joint is bent, The fluid material inside flows and pressure fluctuation occurs, and the pressure is partially increased in the pressure material, and the pressure material hardens and supports in the part that hits the side of the joint when bent from the extended state. Power increases. Therefore, the support force at the time of bending can be stronger than when the joint is extended, the joint is supported and stabilized from the side, and the left and right displacement of the joint can be prevented, and the collateral ligament can be pressurized to assist the joint. The burden can be reduced. On the other hand, when the joint is extended, only moderate pressure is applied, it is not tightened strongly, and the pressurizing material is filled with a fluid substance, so that the skin feels good and the wearing feeling is good. Can do.

  Further, when the pressurizing material is inserted into the pocket and is detachably attached, it is easy to exchange with a supporter having different pressures, and the hardness of the pressurizing material can be adjusted according to preferences and symptoms.

  In particular, if the knee joint supporter is prone to pain in the joint during flexion due to degeneration of cartilage with aging, the side of the joint can be strongly supported with a pressure material when the knee is flexed. A supporter having a high support function at the time of bending can be obtained without tightening.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 6 show a knee support 10 according to a first embodiment of the present invention.
The knee supporter 10 is a cylindrical supporter that covers the entire circumference of the knee joint. The length of the knee supporter 10 is from the top of the knee to the position of the maximum calf, and from the knee pad A that covers the front of the knee to the left and right sides B. A back surface material 41 extending from the knee pad A to the left and right side portions B is sewn to the back surface of the main body 11 sewn on the back side C, and between the main body 11 and the back surface material 41 on the left and right side portions B. An air bag-like pressurizing material 21 is inserted into the pair of left and right pockets 14 formed in the above.

  The main body 11 and the back surface material 41 are made of a polyurethane elastic resin material whose surface is covered with a cloth. As shown in FIG. 1 and FIG. A kneecap opening 13 for projecting the kneecap at a position is provided. Further, the main body 11 is provided with an insertion slit 42 on both the left and right sides of the kneecap opening 13 and at a substantially central position in the length direction of the pocket 14.

  As shown in FIG. 3, the back material 41 has a shape that covers the left and right sides B from the knee pad A, and the left and right outer edges 12 a and 12 b and the lower edge 12 c are sewn to the main body 11, and the upper edge 12 d It is sewn except for a part of the left and right side edges.

The left and right outer edges 12a, 12b of the back material 41 are each arc-shaped bent toward the knee back side C, and are arc-shaped parallel to the outer edges 12a, 12b with a required width W toward the knee pad side A. The main body 11 is sewn along the lines 12e and 12f. As a result, a pair of left and right pockets 14 are formed which are sewn to the main body 11 at the outer edge 12a, the line 12e (12b and 12f), and the lower edge 12c, and have an insertion opening 14a at the upper end.
The pair of left and right pockets 14 extend in the vertical direction as a crescent shape that curves outward at the left and right side portions B sandwiched between the knee pad portion A and the knee back portion C.

  The center portion of the knee pad portion A of the back material 41 and the portion corresponding to the kneecap opening 13 of the main body 11 is heat-pressed to form the bulging portion 15, and the bulging portion 15 is formed on the main body 11. It is exposed from the opening 13.

4 is inserted into the pair of left and right pockets 14 through an insertion opening 14a at the upper end of the pocket 14 or an insertion slit 42 provided in the main body 11. .
The pressurizing material 21 seals air 24 in a bag 22 having a crescent shape substantially similar to the shape of the pocket 14. The bag body 22 is formed of a flexible resin that is easily deformed. In this embodiment, the bag body 22 is formed of a blend resin of polypropylene and a styrene elastomer. In the tensile test of the resin in this embodiment (JIS K-7113 No. 2 type dumbbell test piece, tensile speed 50 mm / min), the yield point strength is 1.90 MPa, and the tensile modulus is 9.0 MPa.
The bag body 22 is manufactured by blowing air 24 from an air blowing port 23 and sealing the air blowing port 23 when the inside of the bag body 22 reaches a required air pressure.
In this embodiment, the air pressure at the time of 90-degree bending compression is 17.8 kPa. The breaking strength in a state where the air 24 is sealed in the bag body 22 is 6.86 kN.

With the pair of left and right pressure members 21 inserted into the pocket 14, the crescent-shaped outer curved portion 25 faces the kneecap opening 13 and is arranged in an X shape centering on the kneecap opening 13. Yes.
In addition, you may attach the arch-shaped side bone which consists of a resin plate or a metal plate to the outer side of each pocket 14 on either side.

  When the knee supporter 10 having the above-described structure is mounted, the pressure member 21 filled with air 24 is disposed along the collateral ligament of the joint, and the ligament is pressure-supported without a sense of incongruity. It becomes a wall and supports the patella from the left and right to stabilize the knee joint, effectively reducing the burden on the knee.

  In particular, when the knee load is small, as shown in FIG. 6 (A), the pressure member 21 is not strongly pressed, and thus the support force is not strong. As shown in (B), the pressure member 21 itself bends at a substantially central portion in the length direction, and the air 24 flows upward and downward to increase the pressure. The pressure is increased by the repulsive force of the internal air 24, and the support force to the collateral ligament is enhanced. Therefore, instead of tightening and fixing around the knee at all times, the tightening force is eased when standing upright with a small burden on the knee, ensuring ease of movement, while the tightening force is strengthened when flexing with a heavy burden on the knee, Knee pain can be effectively relieved.

  Furthermore, since the pressurizing material 21 can be detachably attached to the pocket 14, it can be taken out at the time of washing or the like, and the tightening force (hardness) can be adjusted by exchanging it with a pressurizing material having a different air pressure. Become.

  Furthermore, since the main body 11 and the back surface material 41 are made of an elastic resin material, the knee bending behavior is not hindered. Further, as shown in FIGS. 6A and 6B, since the kneecap is stably supported by the kneecap opening 13, the displacement can be prevented even if the knee is bent. Furthermore, since the bulging portion 15 made of the back surface material 41 extends and fits to the protruding kneecap, only the outer peripheral portion of the knee joint of the main body 11 is not excessively pulled due to the bending of the knee, so that The feeling of pressure can be relieved and the fabric can be prevented from collapsing on the back of the knee. As a result, a comfortable wearing feeling can be obtained without cooling the knee.
