[Knee supporter]
The knee supporter according to the present embodiment is attached to a portion including the knee of the leg, and is provided on the front surface of the knee that supports the front of the knee, the first rear surface of the knee that supports the rear of the knee, and the knee of the leg. A thigh-side front portion that supports the front surface on the thigh side, a thigh-side rear surface portion that supports the rear surface portion of the thigh side, and a tibial front surface that supports the front surface on the shin side with respect to the knee of the leg A cylindrical supporter body including a heel side rear surface portion that supports the rear surface of the shin side, and a second knee rear surface portion that is disposed on the rear surface of the knee and supports the rear surface of the knee together with the first knee rear surface portion The elastic modulus of the supporter body when stretched in the circumferential direction is lower between the first knee rear surface portion and the second knee rear surface portion than in the first knee rear surface portion. Knee supporter.
Further, the knee supporter of the present embodiment has an elastic modulus at 80% elongation in the axial direction of the supporter body of which the knee front surface portion is A, the first knee rear surface portion is B, and the thigh side front surface portion. Where C is the thigh-side rear surface portion, D is the shin-side front surface portion is E, the shin-side rear surface portion is F, and the second knee rear-surface portion is G. 3), when the elastic modulus at 80% elongation in the circumferential direction of the supporter body is BL as the first knee rear surface portion and GL as the second knee rear surface portion, the following formula (4) is satisfied. It is a knee supporter that meets.
0.7 ≦ (B / A) (1)
1 <(C / D) (2)
1 <(E / F) (3)
1 <(BL / GL) (4)
The knee supporter according to the present embodiment has the above-described configuration, so that it has an excellent feeling of fixation with respect to the knee joint and is excellent in the ease of bending and stretching the knee joint (the knee can be easily bent and stretched).

Hereinafter, the above-described effects (improvement of fixation to the knee joint and ease of bending and stretching the knee) will be described in more detail.
According to the study by the present inventors, it has been found that there is a positive correlation between the elastic modulus of the knee support and the feeling of fixation of the knee support to the leg. That is, in the cylindrical knee supporter, the higher the elastic modulus in the circumferential direction, the higher the pressure applied to the leg (that is, the stronger the clamping force on the leg), and as a result, the wearer As a bodily sensation, it was found that the feeling of fixing to the legs was improved.
However, it has been found that when an excessive tightening force acts on the sole of the knee, a sense of incongruity occurs.
Here, the inventors have further studied and found that it is possible to suppress a sense of incongruity by providing a region where the tightening force is suppressed more than the surroundings in the back of the knee. In other words, the region facing the back of the knee is divided into a plurality of portions to provide a first knee rear surface portion and a second knee rear surface portion having different elastic modulus (adhesion pressure), and an elastic modulus at 80% elongation in the axial direction of the supporter body. By satisfying the equation (4) between the axial elastic modulus B of the first knee rear surface portion and the axial elastic modulus G of the second knee rear surface portion (hereinafter also referred to as axial elastic modulus), As a wearer's experience, it was found that the knee joint can be easily bent and extended while improving the sense of fixation to the leg.
Further, as a result of studies by the present inventors, the axial elastic modulus B of the first knee rear surface portion is set to 0.7 times or more of the axial elastic modulus A of the knee front surface portion (that is, the expression (1) is satisfied). It was found that the feeling of fixation to the knee joint is effectively improved.

On the other hand, there is a negative correlation between the elastic modulus of the knee supporter and the elongation of the knee supporter.
In this regard, in the knee supporter of the present embodiment, with respect to the elastic modulus at 80% elongation in the axial direction of the supporter body, the axial elastic modulus D of the thigh-side rear surface portion is the axial elasticity of the thigh-side front portion. When the axial elastic modulus F of the shin side rear surface portion is smaller than the modulus C and smaller than the axial elastic modulus E of the shin side front surface portion (that is, by satisfying the equations (2) and (3)) ) Since the stretch of the thigh-side rear surface and the shin-side rear surface is ensured when the knee joint is bent, the ease of bending and extending the knee joint is improved. More specifically, the thigh-side rear surface of the leg (back side of the thigh) and the back surface of the shin side (back side of the shin) are the front side of the thigh side of the leg (front side of the thigh) and the front surface of the shin side (front side of the shin). It is a surface that has a higher body fat percentage and is located inside when the knee joint is bent. For this reason, the thigh side rear surface part and the shin side rear surface part are required to be stretched during the knee joint bending operation.
Therefore, in the present embodiment, with respect to the axial direction of the supporter body, the axial elastic modulus D of the thigh-side rear surface portion and the axial elastic modulus F of the shin-side rear surface portion are respectively expressed as the axial elastic modulus C and the axial elastic modulus. By making it lower than E, elongation of the thigh-side rear surface portion and the shin-side rear surface portion with respect to bending of the knee is ensured, and as a result, the ease of bending and extending the knee joint is improved.

  In this specification, the elastic modulus at 80% elongation (axial elastic modulus) A of the knee front surface in the axial direction is the center position of the knee front surface (that is, the center in the circumferential direction and the center in the axial direction). This means a value (tensile stress) measured for a measurement width (ie, circumferential length) of 15 mm with the measurement center as the measurement center. The elastic modulus at 80% elongation in the axial direction is the axial elastic modulus B of the first knee rear surface portion, the axial elastic modulus C of the thigh-side front surface portion, the axial elastic modulus D of the thigh-side rear surface portion, and the shin side The same applies to the axial elastic modulus E of the front surface portion, the axial elastic modulus F of the shin side rear surface portion, and the axial elastic modulus G of the second knee rear surface portion.

In the present specification, the “elastic modulus at 80% elongation in the axial direction” is measured by a tensile test under the conditions of a grip width of 15 mm, a grip interval of 15 mm, and a tensile load of 20 N. Here, the direction of the tensile load is measured as the axial direction of the supporter body.
A tensile test for measuring the elastic modulus at 80% elongation in the axial direction was performed by fixing a part of a knee supporter to a tensile tester with a grip width of 15 mm and a grip interval of 15 mm, and a tensile speed of 15 mm / min. The elastic modulus (tensile stress) at the time of stretching by pulling and stretching by 80% is read as a measured value.

In addition, when it is difficult to perform a tensile test on a part of the knee supporter, a 30 mm square test piece may be cut out from the knee supporter and may be performed on the cut test piece. .
The number of tests is five times, and the average value is obtained from three measurement values excluding the maximum and minimum values from the five measurement values, and this average value is adopted as the “80% elongation elastic modulus in the axial direction”. To do.
As a tensile test apparatus, a general tensile tester can be used. For example, an autograph “AGS-X 1kN” manufactured by Shimadzu Corporation can be used.

  In this specification, the measuring method of “elastic modulus at 80% elongation in the circumferential direction” (hereinafter also referred to as circumferential elastic modulus) is that the test direction is the circumferential direction (the tensile direction is the circumferential direction). Is the same as the measuring method of the elastic modulus at 80% elongation in the axial direction (axial elastic modulus).
