Before describing the configuration of the elbow joint supporter 1 according to the present embodiment in detail, the range of motion of the elbow joint, symptoms of pain, and the like will be described below.

Movements of the elbow joint include extension (extending the elbow) and flexion (bending the elbow) in concert with the shoulder joint, as shown in FIG. 2(a). Also, the movement of the forearm includes rotational movement as shown in FIGS. 2(b) and 2(c). Rotational movement consists of pronation, which is the action of turning the palm inward from the body and turning the palm downward, and the action of turning the palm outward and turning the palm upward. There is a supination that is
The range of motion in each motion is 5 degrees of extension, 145 degrees of flexion, 90 degrees of pronation, and 90 degrees of supination.

Based on the range of motion of the elbow joint and the like described above, the symptoms of pain seen in the elbow joint and its peripheral parts will be described.

First, there is pain when lifting a heavy object for a long period of time, and pain when the hand is placed on the elbow with the elbow joint extended. The cause of pain when putting the hand on the elbow with the elbow joint extended is that the elbow is excessively extended beyond the range of motion of extension (hereinafter referred to as hyperextension), and the collateral ligament of the elbow joint is damaged. to (sprain). The elbow joint has three ligaments: the medial collateral ligament, the lateral collateral ligament, and the radial annular ligament. Although they stabilize the joint, pain from hyperextension develops when these collateral ligaments are injured.

Second, pain on the outside of the elbow (thumb side) that occurs when lifting an object, twisting a doorknob, squeezing a towel, or backhanding in tennis (tennis elbow). Twisting motion, tennis forehand motion, and pain on the inner side of the elbow (little finger side) during inappropriate swing motion of a golf club (golfer's elbow). The cause of tennis elbow pain is inflammation of the lateral epicondyle, the lateral bulge below the humerus. In addition, the cause of pain in golfer's elbow is inflammation of the medial epicondyle, which is a raised portion on the medial side of the lower humerus. As described above, one of the causes of pain in tennis elbow and golfer's elbow is the twisting motion of the forearm.

The elbow joint supporter 1 according to the present embodiment stabilizes and protects the elbow joint and its surroundings from pain caused by hyperextension and tennis elbow/golfer's elbow.

Next, an example of the fabric structure of the upper anchor portion 10 according to this embodiment will be described with reference to FIG. 3 .

The warp yarn 50a forming the loop surface floats above one weft yarn 51 (weft yarn 51a, fusion yarn 51b), and three adjacent weft yarns 51 (weft yarn 51a, fusion yarn 51b) float. The weft yarn 51 (weft base yarn 51a, fusible yarn 51b), which sinks through the bottom side of the yarn 51b), repeats 1-3 crossing ups and downs to form a fabric structure.
In addition, the pile yarn 50b forming the loop surface passes over the six adjacent weft yarns 51 (the weft yarn 51a and the fusible yarn 51b) and floats above the two adjacent weft yarns 51 (the weft yarn 51a). , sinks through the lower side of the fused yarn 51b), floats through the upper side of the adjacent two weft yarns 51 (the weft ground yarn 51a and the fused yarn 51b), and the two adjacent weft yarns 51 Repeating 6-2-2-2 crossing ups and downs with the weft yarn 51 (weft ground yarn 51a, fusion yarn 51b) sinking through the lower side with respect to (weft ground yarn 51a, fusion yarn 51b), Construct a woven fabric.
In addition, the elastic yarn 50c forming the loop surface floats above one weft yarn 51 (weft ground yarn 51a, fusion yarn 51b), 51b), the weft yarn 51 (the weft ground yarn 51a and the fusible yarn 51b), which sinks through the lower side, repeats 1-1 crossing ups and downs to form a fabric structure.
Note that the fabric structure of the warp yarns 50a, the pile yarns 50b, and the elastic yarns 50c shown in FIG. 3 is an example, and is not limited to this fabric structure as long as the surface surface can have loops (loop surfaces).

The tightening section 20 replaces the pile yarns 50b constituting the warp yarns 50 in the knitting yarns of the upper anchor section 10 with the above-described warp yarns 50a (hereinafter referred to as "first warp yarns 50a of the tightening section 20"). A warp yarn 50a (hereinafter referred to as a second warp yarn 50d) is used in which crossing ups and downs with the weft yarn 51 are reversed with respect to the warp yarn 50a (hereinafter referred to as a second warp yarn 50d).

That is, as shown in FIG. 4, the warp yarns 50 include first warp yarns 50a that form one surface (for example, a lining surface) of the fabric together with the weft yarns 51, elastic yarns 50c that provide elasticity in the warp direction, and second warp yarns 50d that, together with the weft yarns 51, constitute another surface (for example, the surface surface) of the fabric.
In addition, the weft yarns 51 include weft yarns 51a that constitute the lining surface of the fabric together with the first warp yarns 50a.
In FIG. 4(b), with the weft yarns 51 arranged side by side as a reference, the upper side is the front surface and the lower side is the lining surface.

Next, an example of the fabric structure of the tightening portion 20 according to this embodiment will be described with reference to FIG.

The first warp yarn 50a floats above one weft yarn 51 (weft ground yarn 51a) and sinks below three adjacent weft yarns 51 (weft ground yarn 51a). , and the weft 51 (weft base yarn 51a) are repeated to form a fabric structure.

In addition, the second warp yarn 50d passes above three adjacent weft yarns 51 (weft ground yarn 51a) and floats, and passes below one weft yarn 51 (weft ground yarn 51a). 3-1 cross ups and downs with the weft 51 (weft base yarn 51a) are repeated to form a fabric structure.
The woven structure of the first warp yarns 50a, the elastic yarns 50c, and the second warp yarns 50d shown in FIG. 4 is an example, and the woven structure is not limited to this.

Note that the upper anchor portion 10 (or the tightening portion 20) uses a Jacquard needle loom to attach the warp yarns 50a of the warp yarns 50 (or the first warp yarns) to a plurality of weft yarns 51 adjacent in the warp direction. 50a) are floated on the surface side, and the pile yarns 50b (or the second warp yarns 50d) of the warp 50 are sunk on the back surface side, and letters, figures or symbols or these are formed in a freely open jacquard weave. A pattern consisting of bonds can be partially formed on the facing surface.
In this case, the upper anchor portion 10 has loops (loop surfaces) over substantially the entire surface surface, except for the patterned area. Moreover, when no pattern is formed, the upper anchor portion 10 and the tightening portion 20 are woven by a needle loom.

In addition, the upper anchor portion 10 and the tightening portion 20 have a maximum elongation in the warp direction depending on the materials of the warp yarns 50 and the weft yarns 51 (in particular, the thickness of the elastic yarns 50c and the weft ground yarns 51a) and the number of times the weft yarns 51 are driven. It is possible to freely adjust the degree.
Here, the maximum elongation is defined as "preparing a test piece with a width of 7.0 cm, grasping the full width in the width direction, setting it in a tensile tester (EZ-TEST EZ-L manufactured by Shimadzu Corporation), and then measuring it at intervals of 10 cm. (L0) is marked, a load of 54.4 N is applied, and the length (L1) between marks after holding for 1 minute is divided by L0.

The maximum elongation of the tightening portion 20 in the warp direction is preferably 1.1 to 5, more preferably 1.5 to 3, even more preferably 1.7 to 2.
