Abstract

[PROBLEMS] To cope with both internal rotation movements of an arm centered on an elbow joint while rotating the palm and external rotation movements when the arm is extended centering on the elbow joint from an internal rotation state. It is an object to provide an elbow joint supporter.
A tricot fabric that expands and contracts in two vertical and horizontal directions, and is cut by inclining both ends 2a and 2b in the direction of internal rotation centering on the elbow joint of the arm when the palm is rotated. In addition, both end portions 2a and 2b are formed by being attached, and an elbow rest piece 4 made of rayon fabric is attached to the elbow portion, and a cushioning material 5 is mounted in the elbow rest piece 4 and the cushioning material. 5 is an elbow joint supporter in which a slit 5a is provided in the direction of internal rotation centering on the elbow joint of the arm.

Description

  The present invention relates to an elbow joint supporter adapted to the movement of the elbow joint when the forearm performs pronation.

  There are pronation and supination movements in the palm (see Fig. 3). As seen in the underpass of volleyball, most of the palms are used to circulate the palm in normal competitive sports. The elbow joint can be pivoted around the elbow joint (see Fig. 4), and the elbow joint can be bent when the palm is swung (see Fig. 5). In these cases, , Rather than simple flexion / extension, it is made to rotate inside or outside.

  However, a conventional draping type elbow joint supporter is designed to fit most at a position where the elbow joint is bent slightly (10 to 15 degrees) with the palm of the hand removed.

In addition, many seamless type elbow joint supporters 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 the above-described draping type elbow joint supporter, if the arm is rotated inward or outward around the elbow joint while rotating the palm, the shape of the supporter cannot follow the movement of the elbow joint, Wrinkles may occur inside the supporter.

  In addition, the seamless elbow joint supporter has an almost straight shape from the upper arm to the forearm, which is designed on the assumption that the elbow is flexed and extended with the palm unfolded. However, if the arm part is rotated inward or outward with the elbow joint as the center, the shape of the supporter cannot follow the movement of the elbow joint, and wrinkles may occur inside the supporter.

  In view of the above situation, this device is made of tricot fabric that expands and contracts in two directions, vertical and horizontal, and inclines both ends in the internal rotation direction around the elbow joint of the arm when the palm is rotated. And an elbow joint supporter formed by attaching the both end portions together.

  That is, in this device, a tricot fabric that expands and contracts in both the vertical and horizontal directions is used, and both ends are inclined and slanted in the direction of internal rotation about the elbow joint of the arm when the palm is rotated. In addition, since the both ends are attached, the inner part of the arm rotates in the center of the elbow joint while the palm is circulated. It can handle any turning motion.

  Furthermore, when performing internal rotation movement around the elbow joint while rotating the palm, the supporter fabric is effectively adhered to the skin while being distorted, and conversely, the arm is extended from the internal rotation state around the elbow joint. Since the supporter fabric effectively adheres to the skin even when performing external rotation, the adhesion between the supporter and the skin becomes extremely high.

  Furthermore, if an elbow pad made of a rayon fabric that is resistant to friction is worn, it can cope with movement on the floor, ground, etc. where frictional contact with the supporter is considered.

  In addition, if a cushioning material is attached to the front or inner surface of the elbow pad, the shock at the time of frictional contact can be reduced, and the cushioning material is slit in the direction of internal rotation about the elbow joint of the arm. When the cushioning material is provided, the cushioning material can follow the internal rotation movement around the elbow joint of the arm portion when the palm is circulated.

  It is made of tricot fabric that expands and contracts in two vertical and horizontal directions, and both ends are inclined and cut in the direction of internal rotation centering on the elbow joint of the arm when the palm is circulated, and the both ends are cut. It is formed by wearing, and an elbow pad made of rayon fabric is attached to the elbow part. Further, a cushioning material is mounted in the elbow patch, and the elbow joint of the arm is centered on the cushioning material. Elbow joint supporter with slits in the direction of internal rotation.

Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. Reference numeral 1 denotes a supporter piece made of a tricot fabric which expands and contracts in two directions, both vertically and horizontally. The supporter body 3 is formed by inclining in the direction of the internal rotation centering on the elbow joint of the arm at the time of pronation, and further attaching both ends 2a and 2b.

  In addition, an elbow pad 4 made of rayon fabric is attached to the elbow pad of the support body 3, and the slit 5 a (inclination angle) is inserted into the elbow pad 4 in the internal rotation direction centering on the elbow joint of the arm. The cushioning material 5 provided with 30 degrees) is mounted.

  This device is constructed as described above, and uses a tricot fabric that stretches in the vertical and horizontal directions as the supporter piece 1, and centers on the elbow joint of the arm when the palms of the both ends 2a and 2b are circulated. Inclined in the direction of internal rotation, cuts and is formed by attaching both ends 2a, 2b, so that the arm is rotated around the elbow joint while the palm is circulated. It is possible to deal with any external rotation when the arm is extended around the center.

  Further, in this embodiment, since the elbow pad 4 made of rayon fabric that is resistant to friction is attached, it is possible to cope with the movement on the floor / ground where frictional contact with the supporter body 3 can be considered.

  Further, in this embodiment, the shock absorbing material 5 is mounted in the elbow rest piece 4, so that the shock when the friction contact is made on the floor, the ground or the like can be reduced. Further, the shock absorbing material 5 has the arm elbow. Since the slit 5a is provided in the internal rotation direction around the joint, it is possible to follow the internal rotation around the elbow joint of the arm when the palm is rotated.

  In short, according to this device, both the internal rotation movement around the elbow joint and the external rotation movement when extending the arm section around the elbow joint from the internal rotation state while rotating the palm. An elbow joint supporter can be provided.

The manufacturing process of the supporter for elbow joints which concerns on this device is shown, (a) is a front view of the supporter piece which installed the buffer material in the center part, (b) is the elbow rest attached to the center part of the supporter piece The front view of a piece, (c) is a side view of the supporter main body formed from the supporter piece, (d) is the front view of a supporter main body same as the above.
