Description

  The present invention relates to a supporter, and more particularly, to a supporter useful for preventing sports disorders such as knees and elbows.

Conventionally, as a supporter, a strong surface piece having a hard elastic property in the muscle fiber direction is provided on a part of a cylindrical main body, and when it is attached to a human body, the strong surface piece is pressed against a necessary portion of the muscle and the corresponding portion A contraction force has been proposed to provide an effect equivalent to that of taping (for example, Patent Document 1).
JP-A-4-343868

  By the way, during sports, the knees and elbows are twisted inward (trunk side) around the limb axis, the knees etc. fall down to the trunk side, and the limb axis moves to the trunk side at the knee etc. A bending valgus is generated. Although internal rotation and valgus are necessary for the natural movement of the human body, it is known that if it becomes excessive, damage such as joint injury and ligament damage will be caused. In particular, when performing contact sports such as wrestling where there are many opportunities to receive tackle from the side, it is easy to cause the above obstacles, and conventionally, taping etc. is applied to the knee etc. and excessive internal rotation and valgus occur. It has been done to suppress.

  However, taping is not easy because it requires special knowledge. Therefore, it is desired to use a supporter as disclosed in Patent Document 1 to prevent damage caused by internal rotation or hallux valgus, but the supporter disclosed in Patent Document 1 gives contraction force to a necessary part of muscle. However, it could not effectively prevent excessive internal rotation and valgus of the knees and elbows.

  The present invention has been made in view of the above circumstances, and provides a supporter that is easy to wear and can effectively prevent and protect a knee or elbow failure due to excessive internal rotation or valgus. It is an object.

  In view of the above circumstances, the present invention provides a supporter to be worn on the limb, a body having a shape corresponding to the adherend, and made of a stretchable material covering at least the knee or elbow and the upper and lower sides thereof, A support portion that is provided integrally with the main body and made of a material having a lower elasticity than the main body, and this support portion engages with an anchor portion that fixes the main body to the human body, and the knee or elbow And a connecting part that suppresses displacement of the knee or elbow to the trunk side relative to the limb axis by connecting the anchor part and the engaging part.

  According to this supporter, the knee and elbow are restrained by the support portion. That is, since the engaging portion that engages with the knee or the like is connected to the anchor portion via the connecting portion, even if a force that is displaced to the trunk side acts on the knee or the like, the knee or the like follows the body. Displacement to the trunk side can be suppressed. For this reason, it is possible to effectively prevent so-called internal rotation and excessive valgus generation in which the knee or the like is displaced to the trunk side with respect to the limb axis. In addition, since the support portion is integrated with the main body formed in a shape corresponding to the adherend portion, the support portion does not require troublesome alignment and can be easily mounted.

  As a more specific configuration, the main body is formed in a cylindrical shape into which a limb can be inserted, and the anchor portions are provided on both sides of the knee or elbow to tighten the limb, The connecting portion connects at least one anchor portion of the anchor portion and the engaging portion.

  This configuration has a function of preventing excessive internal rotation and valgus as described above in the configuration of a general cylindrical supporter covering the knee or elbow and the upper and lower sides thereof. In addition, as above-mentioned, a connection part should just connect an anchor part and engagement part of at least one side, but according to the structure which connects both anchor parts and engagement parts, it is engaged. Since the force acting on the portion can be dispersed and supported, the restraining force of the knee and the like by the support portion can be enhanced and the mounting stability of the supporter can be enhanced.

  The engaging portion may have any shape that can be engaged with a knee or elbow portion, but is preferably formed in a shape surrounding the knee or elbow.

  According to this configuration, since the knee and elbow are surrounded by the engaging portion, the engaging portion can be more reliably and stably engaged with the knee or the like.

  In addition, the engagement portion may be anything that connects the engagement portion and the anchor portion so as to suppress displacement of the knee or elbow to the trunk side relative to the limb axis, but intersects the limb axis. It is suitable to be formed.

  According to this configuration, the direction in which the knee or the like is displaced toward the trunk side and the direction of the connecting portion become closer to parallel, so that the restraining force of the knee or the like by the support portion can be further increased.

  As another specific configuration of the supporter as described above, the main body has a clothing type to be worn on the upper half of a human body, the engagement portion is formed to engage with an elbow, and the anchor portion is It may be formed to engage with the shoulder.

  In this configuration, the elbow is restrained by the support portion with the shoulder as a fulcrum, thereby preventing excessive internal rotation and valgus of the upper limb (arm).

  The support portion is preferably provided on the inner peripheral surface of the main body so as to protrude inward from the inner peripheral surface.

  According to this configuration, the support portion comes into contact with the human body, and further, the contraction force of the main body acts from the outside thereof, thereby increasing the frictional force between the support portion and the human body. Therefore, the support portion is less likely to be displaced with respect to the human body, and the restraint of the knee or the like by the support portion is improved.

  According to the supporter of the present invention, excessive generation of so-called internal rotation and valgus, in which the knee and elbow are displaced inward with respect to the limb axis, can be effectively prevented. Moreover, since the support part for restraining the knee and elbow is integrated with the main body having a shape corresponding to the adherent part, troublesome alignment of the support part is unnecessary, and it can be easily attached. .

  A first embodiment of the present invention will be described with reference to the drawings.

  1 to 3 show a supporter according to the present invention. The supporter 10 of this embodiment is attached to the leg 1, and FIG. 1 is a front view of the right leg supporter 10 attached to the leg 1 (viewed from the front of the human body), and FIG. 2 is a side view. FIG. 3 is a cross-sectional view.

  The supporter 10 is attached to a portion from the thigh 2 to the crus 4 so as to cover the joint portion of the knee 3, and includes a cylindrical main body 12 made of an elastic material, and the main body. It is comprised from the support part provided integrally.

  The support portion fixes the supporter 10 with respect to the leg 1 and restrains the movement of the knee 3. The support portion is made of a material having a lower elasticity than the main body 12 and is sewn to the main body 12 so that the main body is sewn. 12 is integrated. Specifically, the support portion includes an anchor portion 14, an engagement portion 16, and a connecting portion 18. In FIG. 1 and FIG. 2, the convenience support portion is indicated by a solid line.

  The anchor portions 14 are provided at both upper and lower ends of the main body 12. Each anchor portion 14 is provided by sewing a band-shaped member made of, for example, a strong rubber material over the inner periphery of the main body 12, and the anchor portion 14 connects the thigh 2 and the crus 4. The supporter 10 is fixed to the leg 1 by tightening each.

  The engaging portion 16 is provided by sewing an annular member made of urethane resin or the like to the main body 12. As shown in FIGS. 2 and 3, the size of the engaging portion 16 is, for example, a size (inner diameter) such that the patella portion is substantially fitted. Can be engaged.

  The connecting portion 18 connects the engaging portion 16 and the anchor portion 14 together by connecting the engaging portion 16 and the upper (thigh 2 side) anchor portion 14, and is a low stretch material. A band-shaped member made of is provided by being sewn to the main body 12, the engaging portion 16, and the anchor portion 14, respectively. The connecting portion 18 is provided so as to prevent the engaging portion 16 from being displaced to the trunk side relative to the limb axis O when attached to the leg 1. It is provided so that the engaging part 16 and the anchor part 14 may be connected linearly along the side surface.

  In addition, as shown in FIG. 3, the support part (anchor part 14, the engaging part 16, and the connection part 18) is sewn in the state which protruded to the human body side rather than the inner surface of the main body 12, Thereby, supporter mounting | wearing is carried out. In the state, the support portion is in direct contact with the leg 1.

  According to the supporter 10 according to the present invention as described above, the knee 3 can be effectively restrained by the support portion, and thereby, a disorder such as joint injury or ligament damage of the knee 3 due to so-called excessive internal rotation or valgus. Can be prevented in advance. That is, in a state where the supporter 10 is attached to the leg 1, the engaging portion 16 is engaged with the knee 3 by fitting the patella portion into the engaging portion 16. And since this engaging part 16 is connected as mentioned above with respect to the anchor part 14 which fastens the leg 1 through the connecting part 18 made of a low stretch material, it is on the trunk side with respect to the knee 3. Even when a force (displaced in the direction indicated by the white arrow in FIG. 1) is applied, a force that resists this acts, and the displacement of the limb axis O toward the trunk side of the knee 3 is effectively suppressed. Become. Therefore, the internal rotation in which the knee 3 is excessively twisted to the trunk side around the limb axis O, or the valgus in which the knee 3 is excessively tilted to the trunk side and the limb axis O is bent inward at the knee 3. Generation | occurrence | production can be prevented effectively, As a result, obstacles, such as a joint injury of the knee 3 by these excessive internal rotations and valgus, ligament damage, can be prevented and protected.

  In particular, the support portion is provided so as to protrude from the inner surface of the main body 12 toward the human body as described above, and thereby, the support portion directly contacts the human body and the contraction force of the main body 12 acts from the outer side to thereby closely contact the human body. It is configured as follows. Therefore, the support portion is not easily displaced with respect to the leg 1, and the displacement of the knee 3 toward the trunk is effectively suppressed.

  Moreover, in this supporter 10, since the support portion is integrated with the main body 12 as described above, the engaging portion is passed through the leg 1 through the supporter 10 (main body 12) in the same manner as this general supporter. It can be easily attached by simply fitting the patella to 16. Therefore, it can be easily attached to the leg 1 to prevent the leg 1 from being damaged due to internal rotation or valgus.

  In this supporter 10, the engaging portion 16 and the upper (thigh 2 side) anchor portion 14 are connected via the connecting portion 18 as described above, whereby the trunk of the knee 3 with respect to the limb axis O. Although the displacement to the side can be suppressed, the form of the connecting portion 18 is not limited to the above embodiment as long as the displacement of the knee 3 to the trunk side can be suppressed. For example, as shown in FIGS. 4-7, the connection part 18 may be provided.

  That is, FIG. 4 shows a connecting portion that crosses the limb axis O by connecting a portion of the engaging portion 16 on the inner surface side of the leg 1 and a portion of the anchor portion 14 on the outer surface side of the leg 1. 18 is an example. According to such a configuration, the angle formed between the displacement direction of the knee 3 (the left-right direction in FIG. 1) and the connecting portion 18 is smaller (becomes parallel) than that in FIG. The displacement of 16) can be more effectively suppressed. FIG. 5 shows an example in which the engaging portion 16 and the lower (crus 4 side) anchor portion 14 are connected by a connecting portion 18 in the same way as FIG.

  6 and 7 are examples in which the engaging portion 16 is connected to the upper and lower anchor portions 14, and FIG. 6 is a first connecting portion 18a corresponding to the connecting portion 18 in FIG. 1 and the connecting portion 18 in FIG. 7 is provided with a second connecting portion 18b corresponding to the connecting portion 18 of FIG. 4 and a second connecting portion 18b corresponding to the connecting portion 18 of FIG. Are provided. Thus, according to the structure which connected the engaging part 16 and the anchor part 14 of the up-and-down both sides by connection part 18a, 18b, the force which acts on the knee 3 (engaging part 16) can be disperse | distributed and can be supported. As compared with the case where the force acting on 3 is supported by only one anchor portion 14, the mounting displacement of the supporter 10 is less likely to occur. Therefore, there is an advantage that the restraining force of the knee 3 by the support portion can be increased and the mounting stability can be improved.

  In the above embodiment, an annular engagement portion 16 is provided to restrain the knee 3, and the patella portion is fitted into the engagement portion 16. However, the engagement portion 16 is strictly annular. It does not need to be formed, and if it is a shape that engages (hooks) the knee 3 (patella), for example, as shown in FIGS. It may be. However, in order to engage the engaging portion 16 with the knee 3 more reliably and stably, it is desirable that the engaging portion 16 is formed in a shape surrounding the knee 3 as a center.

  Furthermore, in the supporter 10 of the said embodiment, although it has the structure which provided the anchor part 14, the engaging part 16, and the connection part 18 as a support part, for example, as shown in FIG. The other support line 19 having the above may be further provided, and the support line 19 may be pressed against a necessary part to have a function of applying a contracting force to the part.

  1 to 9 show the right leg supporter 10, the left leg supporter has a configuration in which the connecting portion 18 is provided symmetrically with respect to the limb axis O in the right leg supporter 10. It becomes.

  Next, a second embodiment of the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the part which is common in 1st Embodiment, and description is abbreviate | omitted (same about 3rd Embodiment).

  The supporter 20 shown in FIG. 11 is attached to the arm 5 (right arm). Specifically, it is attached to a portion from the upper arm portion 6 to the forearm portion 7 so as to cover the joint portion of the elbow 8, and like the leg supporter 10 described above, a cylindrical shape made of an elastic material. The main body 12 and a support portion provided integrally with the main body 12. Then, the supporter 20 is mounted on the arm 5 with the engaging portion 16 engaged with the elbow 8, so that the displacement of the elbow 8 toward the trunk side is suppressed by the support portion.

  According to such a supporter 20 for an arm, it becomes possible to prevent and protect a failure such as a joint injury or ligament damage caused by an excessive internal rotation or valgus of the arm 5.

  Although FIG. 12 shows a supporter 20 for the right arm, the supporter for the left arm has a configuration in which the connecting portion 18 is provided symmetrically with respect to the limb axis in the supporter 20 for the right arm.

  Next, a third embodiment of the present invention will be described with reference to FIG.

  The supporter 30 shown in FIG. 12 is for preventing and protecting obstacles such as joint trauma and ligament damage caused by the internal rotation and valgus of the arm 5, similarly to the supporter 20 of the second embodiment. The configuration is different from the supporter 20 of the second embodiment in the following points.

  That is, the supporter 30 is a clothing-type supporter, and has a structure in which a support portion is provided on the main body 12 made of an elastic material formed so as to be worn on the upper body of the human body (including the arm 5). Yes. And as an anchor part, instead of the upper anchor part 14 of the second embodiment, an annular part 22a that engages with the peripheral part of the shoulder ridge 9 (right shoulder), and a belt-like shape extending in the neck direction from this annular part 22a The anchor portion 22 including the portion 22b is provided. The anchor portion 22 is made of a material having a large friction coefficient, and the annular portion 22 a is formed so as to fit the peripheral portion of the shoulder peak 9.

  That is, the supporter 30 of the third embodiment is configured such that the anchor portion 22 supports the force acting on the elbow 8 by the engagement with the peripheral portion of the shoulder ridge 9 and the frictional force. According to the supporter 30 of the third embodiment as described above, since the upper arm portion 6 is not tightened by the anchor portion, the feeling of pressure is reduced, and there is an advantage that the feeling of wearing is improved accordingly.

  Here, only the configuration on the right arm side of the supporter 30 has been described, but the configuration on the left arm side is a configuration in which the connecting portion 18 is provided symmetrically with the illustrated one.

  By the way, the supporters 10, 20, and 30 described above are some examples of the embodiment of the supporter according to the present invention, and the specific configuration thereof can be appropriately changed without departing from the gist of the present invention. is there. In particular, the specific configuration of the support portions (anchors 14 and 22, the engaging portion 16 and the connecting portion 18) that restrain the knee 3 and the elbow 8 is the displacement of the knee 3 and the elbow 8 toward the trunk side with respect to the limb axis. Can be appropriately changed so that the above can be more effectively suppressed. Needless to say, the leg supporter 10 and the arm supporters 20 and 30 can be applied to each other as appropriate. Further, the knee supporter may be a clothing type such as spats or tights. The support portion may be formed on the main body 12 by a technique such as welding or resin impregnation.
