Description

  The present invention relates to an O-leg correction device for correcting an O-leg.

  As a conventional O-leg corrector, for example, a belt-like configuration disclosed in Patent Document 1 is known. This O leg corrector forcibly tightens the O leg by tightening the thigh, knee and lower leg of both legs with a thigh belt, knee belt and lower leg belt, respectively. It is something to be cured. However, such correction by the belt method tends to return to the O-leg immediately after correction, so that it is difficult to obtain a sufficient effect, and there is a possibility that pain may occur in joints such as knees and crotch.

  Patent Document 2 discloses an O-leg correction training device in which left and right sole plates are rotatably provided on a base. In this training device, the user stands with his / her feet on the left and right soles, and the feet are pivoted so that the forefoot is on the outside and the rear foot is on the inside. The bottom plate rotates so that an exercise load is applied by a spring force or the like acting between the base and the sole plate. However, according to this configuration, since the posture of the user during training is limited to the standing position, not only the training environment is easily restricted, but also the weight of the user acts on the sole plate, so There was a risk that smooth rotation would be hindered. In addition, since the center of rotation of the sole plate is substantially at the center of the sole plate, it is difficult to largely rotate the sole plate, and it is difficult to generate an effective training load.

By rotating the pair of foot orthoses 10 and 10, a good training effect for preventing O-legs can be obtained.

  The foot orthosis 10 is formed in a sandal shape by providing a band-shaped upper portion 12 that covers the instep of the foot F on a sole portion 11 formed in a plate shape according to the shape of the foot F. 12, a portion in contact with the outside of the instep of the foot F is a thick reinforcing portion 12 a. The surface of the sole 11 is formed so as to be slightly inclined from the outside to the inside, and in order to enhance the fit of the sole and facilitate the rotational movement of the pair of foot orthoses 10, 10, The position corresponding to the thumb is formed in a concave shape, and the position corresponding to the toe and the index finger is raised.

  In addition, a covering portion 13 is provided on the sole portion 11 so as to be connected to the upper skin portion 12 and cover the outside of the foot F from the reinforcing portion 12a toward the heel side of the foot F. The covering portion 13 is provided with a hemispherical rear fulcrum protrusion 14 so as to protrude to the rear side of the heel of the foot F. The rear fulcrum protrusion 14 is preferably formed of a material having a high frictional resistance such as resin or rubber so as to easily maintain a state where the rear fulcrum protrusion 14 is in contact with a floor surface such as flooring.

  The toe side connecting member 20 is made of an elastically extensible member such as a helical spring or a rubber string, and is provided so as to connect the toe portions of the pair of foot orthoses 10 and 10. The toe side connecting member 20 is preferably detachably attached to the pair of foot orthoses 10, 10. In this embodiment, hook portions 20a, 20a are provided at both ends of the toe side connecting member 20 made of a helical spring. The hook portions 20a and 20a are locked in locking holes 10a and 10a formed in the toe portions of the pair of foot orthoses 10 and 10, respectively. The connecting position of the pair of foot orthoses 10 and 10 by the toe side connecting member 20 is preferably as close as possible to the tips of the foot orthoses 10 and 10, but is not necessarily the most advanced.

  The heel side connecting member 30 is provided so as to connect the heel portions of the pair of foot orthoses 10, 10. The heel side connecting member 30 is made of a flexible member, and is formed so as not to expand and contract so that the distance between the pair of foot orthoses 10 and 10 does not increase. The heel side connecting member 30 can be integrally formed with the pair of foot orthoses 10, 10 using, for example, a resin material.

  Next, a training method using the O-leg correction device 1 having the above-described configuration will be described. First, a pair of foot orthoses 10 and 10 are respectively attached to both feet, both legs are extended in a state of lying on the floor, and the rear fulcrum protrusions 14 and 14 of both heels are brought into contact with the floor surface to make a pair of foot orthoses 10. , 10 with the toe side facing upward. And as shown in FIG. 4, the operation | movement which rotates both feet F and F in the direction of an arrow is carried out against the elastic force of the toe side connection member 20 by using the rear fulcrum protrusions 14 and 14 as fulcrums. The cause of the O leg is that both knees rotate inward by turning the femurs of both legs inward, and the distance between both knees increases. By rotating both legs outwardly with the external rotatory muscle force, both knees can be maintained in a normal state, and the O-leg can be corrected.

  According to the O-leg correction device 1 of the present embodiment, not only the structure is simple and easy to wear, but also the user can perform training in the supine position, so a load is applied to muscles other than the external rotator muscle. Can be intensively trained external rotator muscle necessary for O-leg correction. Therefore, a good O-leg correction effect can be obtained with an inexpensive configuration. In addition, training can be performed while relaxing in the supine position such as watching TV or reading at home, etc., so it is also excellent in continuity. Furthermore, by strengthening the external rotator muscle, it is possible to obtain the effect of hip up and pelvic tightening adjustment.

  In addition, since the rear fulcrum protrusions 14 and 14 of both the arms serve as fulcrums for the rotation of both feet, the rotation radius from the fulcrum to the toe can be increased as compared with the conventional configuration, which also provides a training effect. Can be increased. In addition, the rear fulcrum protrusions 14 and 14 can suppress wrinkle pain caused by contact with the floor surface and prevent displacement during training. However, the rear fulcrum protrusions 14 and 14 are not essential in the present invention. , 14 may be omitted.

  In addition, the toe side connecting member 20 can be detachably provided to the pair of foot orthoses 10, 10 so that the user can appropriately select from a plurality of types having different load strengths, and can be easily replaced and used. it can. However, the toe side connecting member 20 may be integrally formed so as not to be separated from the pair of foot orthoses 10 and 10.

  Further, since the heel side connecting member 30 holds the heel portions of the pair of foot orthoses 10 and 10 so that the distance between them does not increase, the pair of foot orthoses 10 and 10 slide and rotate on the floor surface during training. It is possible to prevent the fulcrum from being displaced. It is preferable that the heel side connection member 30 has flexibility so that smooth rotation operation of a pair of foot orthoses 10 and 10 may not be prevented. Since the heel side connecting member 30 is flexible, the pair of foot orthoses 10 and 10 can be folded and stored in a shoe case or the like during transportation, which is convenient for carrying. However, the heel side connection member 30 is not essential in the present invention, and may be configured without the heel side connection member 30 as long as the positional deviation of the rotation fulcrum can be prevented by other means. In addition, the heel portions of the pair of foot orthoses 10 and 10 can be directly connected without providing the heel side connection member 30.

  As described above, the O-leg correction device of the present invention is suitable for the user to train in the supine position, but can also perform training in the standing position as well as the supine position. The toe side connecting member 20 can be expanded and contracted by bringing the heel portions on the back side of the sole portions 11 and 11 of the foot orthoses 10 and 10 into contact with the floor surface and rotating the toe side outward with the heel portion as a fulcrum. it can. In this case, as shown in FIG. 5, a lower fulcrum projection 15 such as a hemisphere that protrudes toward the sole side is provided on the heel portion on the back side of the sole portion 11, and the lower fulcrum projection 15 is brought into contact with the floor surface to lower the bottom. By rotating around the fulcrum protrusion 15, it is possible to easily perform a rotation motion around the buttocks and enhance the training effect. A plurality of sliding protrusions 16 extending concentrically around the lower fulcrum protrusion 15 may be provided on the back side of the sole 11. The sliding protrusion 16 preferably has a smooth contact surface with the floor surface so that the frictional resistance with the floor surface is reduced. For example, the sliding protrusion 16 is configured by adhering an arc-shaped metal plate. can do. Thereby, the rotation operation around the lower fulcrum protrusion 15 can be performed more smoothly.
