DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leg supporter having excellent physiological comfort.

[0002]

2. Description of the Related Art From the viewpoint of comfort when worn, for example,
There have been various proposals for varying the wearing pressure of each part of the pantyhose. For example, in Japanese Patent No. 282090, a comfortable wearing feeling is given by gradually decreasing the wearing pressure from the arch to the ankle, the calf, and the thigh.
Further, there has been proposed a device for controlling a vein by means of stocking, which is described in, for example, Japanese Patent Publication No. 7-98053 and Japanese Patent Application Laid-Open No. 8-199404.

[0003]

In the above-mentioned stockings for controlling veins, in order to promote venous return to a certain extent, a certain amount or more of tightening force is applied to the legs by an optimal wearing pressure balance. Although it is knitted, it is necessary to give some strong power to the feet in order to effectively return the veins. However, when the power was increased, the knitted fabric became stiffer and the elasticity was reduced in proportion thereto, and as a result, the legs were cramped or could not give strong power to exercise. The quality of such venous return has a considerable effect on leg fatigue and swelling.

BEST MODE FOR CARRYING OUT THE INVENTION In the blood circulatory system, a push-up force in accordance with the hydrostatic pressure against the gravity is required in human physiology. The structure ensures the elasticity that can follow the bending and stretching movement, and the structure on the back of the leg with little change in shape is firmly supported as a mesh knitting structure, while the shape change below the knee is less. The front has a mesh knitting structure with excellent supportability, and the back has a rib knitting (rubber knitting) structure with a knitting structure for firmly supporting the calf portion. The wear pressure balance is weakened from the ankle to the thigh to push up blood. That is, it has a wearing pressure balance according to the hydrostatic pressure balance in human physiology, and in order to perform sufficient venous return, the wearing pressure of the thigh in the standing position is 9 to 17
gf / cm ² , the wearing pressure of the lower leg (calf) is 14 to
28 gf / cm ² , ankle wearing pressure is 17 to 35 gf / c
It is in the range of m ^2. In addition, as an example of the optimum balance in such a range, when the ankle is set to 100, the calf is gradually reduced to 80 to 85 and the thigh is set to 50. The wearing pressure was measured using an air-pack type clothes pressure converter AM13037 manufactured by AIM Co., Ltd. In addition, in the above-described configuration, the use of fibers in which ceramic is kneaded in at least a part of the knitting material can enhance the heat retaining effect, and also contributes to an increase in heart rate and promotion of venous return. Hereinafter, the configuration will be specifically described with an example.

[0006]

Example 1 48 denier fur vest
Fiber (trade name; manufactured by Farvest Co., Ltd .; synthetic fiber kneaded with ceramic) is used as the backing thread.
Using denier polyurethane yarn as a core yarn and single covering in which 70 denier bulky nylon yarn was covered from one direction, a knitting machine was used to knit from the ankle to the thigh into a tubular shape. In such a knitting, the first half from the knee to the thigh (the part that becomes the front side when worn) is a plain knitting structure (plain knitting structure) with a side yarn and a back yarn attached, and from the knee to the thigh. (The part that becomes the back side when worn) and the front part from the ankle to the knee (the part that becomes the front side when worn)
Is a spiral miss knitting structure with 1: 1 alternating needles, that is, a knitting structure in which the surface yarns are alternately missed (skip knitting) at a ratio of 1: 1 in the course direction, and the latter half (wearing) from the ankle to the knee. In this case, the leg supporter of the present invention has a spiral miss knitting structure with the same needle of 1: 1, that is, a knitting structure in which face yarns are alternately missed (skip knitting) at a ratio of 1: 1 in the wale direction. I got FIG. 1 shows the configuration of the leg supporter of the present invention thus obtained. In the figure, 1 is the upper part of the knee from the knee to the thigh, 2 is the lower part of the knee from the ankle to the knee, 3 is the front (front) of the upper part of the knee, 4 is the back (rear), 5 is 5 The front of the lower part of the knee (the front side), 6 is the rear side (calf), 7 is the wearing mouth, and 8 is the ankle. The wearing pressure of the leg porter of the present invention obtained by such a material and knitting was 14 gf / cm ^{2 for} the thigh in the upright position and 23 gf / cm for the lower leg (calf).
cm ² and ankle 28 gf / cm ² , the values of which gradually increased. The wearing pressure was measured by an air-pack type clothing pressure converter AM1303 manufactured by AIM Co., Ltd.
7 was measured using a 20-year-old torso with an average body shape standing upright. In the evaluation, the result of measuring a single cardiac output when wearing this was 48.82 for a bare foot of 37.97 when stepping on the foot, and 52.82 for a bare foot of 44.98 when the chair was at rest. The value of the leg tights was 65.21. The leg tights manufactured by blended yarn of commercially available cotton and synthetic fiber measured as the control section were 37.21 for the former and 4 for the latter.
It was 2.78 (the unit was milliliter). In addition, the heart rate was 92.87 of the present invention, compared to 106.30 when the bare foot was stepped on, and 90.34 of the present invention, compared to 90.71 of the bare foot when the chair was at rest. In the above-mentioned commercially available products, the former value was 96.29, and the latter value was 84.48 (unit: times / minute). In addition, the wearing pressure of the commercially available product used as a target section is ankle 9.27, calf 16.13, and thigh 18.13 (all units are gf / cm ² ). Furthermore, when the skin temperature of the lower leg was measured for the heat retention effect, the skin temperature before wearing was 32.2 ° C.
After 3 minutes, the temperature reached 34.4 ° C.

[0007]

According to the structure of the present invention, the warming effect can be enhanced by the fiber into which the ceramic is kneaded, and the heart rate is increased and the venous return is promoted. As a result, swelling and fatigue can be suppressed.
