Description

  The present invention relates to a knee joint supporter that has excellent breathability in the back body of the knee joint and that can closely contact the skin during knee extension and flexion movements and a method for manufacturing the same.

  Conventional supporters for knee joints are designed to fit best at a position where the knee joint is slightly bent (about 10 to 15 degrees) as shown in FIG. 4 is divided into an upper piece 4a and a lower piece 4b, and then the upper piece 4a and the lower piece 4b are provided with a predetermined angle at the rear, and the lower end portion and the upper end portion are attached to form a back body piece. In addition, both side parts of the main body rear body piece 4 are attached to both side parts of the main body front body piece 1 integrally formed by cutting.

In addition, many seamless type supporters for knee joints have been proposed (Japanese Patent Laid-Open No. 9-285587, Japanese Patent Laid-Open No. 2005-185629, Japanese Utility Model Publication No. 56-11879, Utility Model Registration No. 3057223).

  However, in conventional draping type knee joint supporters, the supporter body cannot follow the movement of the knee joints by repeating the flexion and extension movements of the knee joints, and the supporter may be displaced downward from the thigh. There are drawbacks such as wrinkles in the body.

  In addition, there are disadvantages such as a sense of incongruity because the upper and lower pieces of the back part of the main body bite into the inside of the knee when the knee is bent and stretched.

  On the other hand, in the seamless type knee joint supporter, since the shape is tapered from the thigh to the lower leg, the supporter body can follow the movement of the knee joint by repeatedly bending and extending the knee joint. There are disadvantages such as slippage downward from the thigh and wrinkles in the supporter body.

  Furthermore, in both the conventional draping type and seamless type knee joint supporters, the back body part is made of a material that is not breathable, so that it cannot cope with sweating due to movement of the knee joint. is there.

  In view of the above circumstances, the present invention provides a front body piece that protects the front surface of the knee joint periphery cut with a tricot fabric that expands and contracts in two vertical and horizontal directions, and a tricot mesh that has excellent breathability that expands and contracts in two vertical and horizontal directions. The present invention proposes a knee joint supporter formed by attaching a rear body piece that protects the posterior surface of the peripheral edge of the knee joint, which has been cut and formed with a cloth, and a method for manufacturing the same.

  That is, in this invention, since the tricot mesh fabric excellent in air permeability that expands and contracts in the vertical and horizontal directions is used as the back body piece, it does not stuffy in response to sweating due to movement of the knee joint.

  Further, in the present invention, since the tricot fabric that stretches the front body piece and the back body piece in the vertical and horizontal directions is used, the knee joint extends from the extended position (0 degree position) to the bent position (about 20 degrees). Therefore, it can cope with any movement of flexion and extension of the knee joint.

  In addition, the fabric of the front body piece effectively adheres to the skin on the front of the thigh and lower leg at the time of flexion movement from extension of the knee joint. Since it adheres effectively to the skin on the back of the lower leg, in this invention, the adhesion between the supporter main body and the skin becomes extremely high.

  Further, in the supporter according to the present invention, the back body piece is integrally cut and formed without being attached, so that when the knee is bent and stretched, the attached portion does not bite into the inside of the knee and there is no sense of incongruity.

  Furthermore, if a knee pad made of rayon fabric that is resistant to friction is attached to the lower part of the front body piece, it can cope with movement on the floor, ground, etc. where frictional contact with the supporter main body is considered.

  In addition, if a cushioning material is attached to the front surface or the inner surface of the knee pad piece, the impact at the time of frictional contact can be reduced.

  In addition, the supporter according to the present invention may be mounted under an existing padded supporter.

  On the other hand, in the supporter according to the present invention, in order to increase the fit feeling to the skin of the front of the thigh and the lower leg, the upper piece and the lower piece are cut and formed separately and attached to the end portions. It is preferable to use a front piece.

  Furthermore, as a method of manufacturing a supporter that enhances the feeling of fit, the upper piece has a convex shape with its upper end at its center, the lower end has a concave shape with its center as its apex, and both sides extend from the upper end to the lower end. Cut to form an appropriate reduced diameter, the lower piece has a convex shape with its lower end at its center, its upper end has a concave shape with its center as its apex, and both sides extend from the lower end to its upper end. The upper piece and the lower piece are formed by cutting the upper piece and the lower piece together by attaching the lower end portion and the upper end portion thereof, and further cutting the rear piece piece. And a method of attaching both sides of the back body piece.

    A front body piece that protects the front surface of the knee joint periphery that is cut with a tricot fabric that expands and contracts in the vertical and horizontal directions, and a knee joint peripheral rear surface that is cut with a highly breathable tricot mesh fabric that expands and contracts in the vertical and horizontal directions. In the knee joint supporter formed by attaching the back piece to protect both sides, the upper piece has a convex shape with the upper end at the center and the lower end at the center. It is concave, and both sides are cut and formed so as to have an appropriate reduced diameter from the upper end to the lower end, and the lower piece has a convex shape with the lower end at the center and the upper end is at the center. It is concave, and both sides are cut and formed to have an appropriate reduced diameter from the lower end to the upper end, and the upper piece and the lower piece are attached to the lower end and the upper end to form a front body piece, and Cut the back body piece, and with the above front piece Knee supporter and a manufacturing method thereof for manufacturing and sewn on both sides of the body piece.
