The present invention relates to compression socks.

In the blood circulation of the human body, the blood that flows through the legs returns to the heart against gravity, so it is known that the calf muscles act as a pump as a "second heart" and help blood circulation. It is However, if you work while standing or sitting for a long time, the movement of the calf muscles weakens and the action of the blood circulation pump becomes difficult to work, which causes swelling and the like. Therefore, in recent years, by applying more tightening pressure (wearing pressure) from the ankle to the calf when worn than ordinary socks or stockings, the function to support the pump action (hereinafter simply referred to as "support function") ) and have been developed to reduce swelling.

While normal socks have a pressure of about 5 to 15 hPa at the ankle, conventional compression socks have the highest pressure at the ankle of about 20 to 40 hPa, and the pressure is gradually loosened. Many of them had a support function by pulling the calf muscles upward. Patent Literature 1 discloses a compression stocking having a shape of a plurality of diagonal radial stripes as a "calf lifting area" that performs a support function.

Japanese Patent No. 6904526

However, it was found that workers who often stand up, such as nurses, caregivers, and childcare workers, avoid wearing compression socks. It was found that people felt stressed because it took a lot of force and time. On the other hand, conventional techniques such as Patent Document 1 do not disclose compression control from the viewpoint of facilitating the putting on and taking off of compression socks, shortening the time required for putting on and taking off the socks, and reducing stress.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide compression socks that can be easily put on and taken off without impairing the function of reducing swelling.

In order to solve the above problems, one of the typical compression socks of the present invention has a lower value of compression in the ankle region than in the calf region adjacent to the ankle region. . Also, the pressure applied to the calf convex region of the calf region may have a lower value than the pressure applied to the portion of the calf region adjacent to the ankle region.

According to the present invention, the compression socks can be easily put on and taken off without impairing the function of reducing swelling.
Problems, configurations, and effects other than those described above will be clarified by the description in the following embodiments.

FIG. 1 is a schematic diagram showing a leg portion. FIG. 2 is a schematic diagram showing a compression sock according to the first embodiment. FIG. 3 is a schematic diagram showing the foot region of the compression sock according to the third embodiment worn on the foot. FIG. 4 is a schematic diagram showing the foot region of the compression sock according to the fourth embodiment worn on the foot.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment. Moreover, in the description of the drawings, the same parts are denoted by the same reference numerals.
In the present disclosure, compression socks are not particularly limited in terms of length in the longitudinal direction, shape of toes, or names as long as they cover at least ankles and calves, and include, for example, elastic stockings.
In the present disclosure, the longitudinal direction of the compression sock is referred to as upward from the toe to the opening, and the opposite direction is referred to as downward.

[First embodiment]
FIG. 1 is a schematic diagram showing a leg portion. B indicates the position of the ankle, and the ankle part 10 corresponds to the area from point b, which is the ankle part, to the vicinity of the slightly thinned Achilles tendon. A calf portion 20 extends upward from the ankle portion 10 to near the point d below the knee.
Point b1 is the portion below the calf adjacent to the ankle (hereinafter referred to as “lower calf adjacent portion”), and point c is the portion near the calf that has the greatest bulge in the longitudinal direction (hereinafter referred to as This is referred to as the “calf convex portion”).

FIG. 2 is a schematic diagram showing a compression sock according to the first embodiment. The regions of the compression sock that contact the ankle portion 10 and the calf portion 20 are referred to as the ankle region 10 and the calf region 20, respectively, and are denoted by common reference numerals. Hereinafter, unless otherwise specified, common designations and reference numerals will be used to describe regions of the compression sock that come into contact with various parts of the foot. Further, the pressure applied to a predetermined region of the compression sock means the pressure applied to a predetermined portion of the foot that comes into contact when the sock is worn.

Various methods are conceivable for how to control the pressure applied when knitting socks, but in general, a method of adjusting by appropriately combining the knitting method, knitting yarn, and stitch density is adopted. In order to knit so that the pressure is increased, any one of knitting an FTY yarn as the back yarn, inserting a rubber yarn, and knitting with a small stitch may be adopted. On the other hand, in order to reduce the wearing pressure, one of the following methods may be adopted: not knitting the FTY yarn into the back yarn, not inserting the rubber yarn, or knitting with a large stitch.

The compression sock according to the first embodiment is characterized in that the pressure in the ankle area (see point b) is set lower than the pressure in the area adjacent to the lower calf (see point b1). At that time, the pressure applied to the ankle region may be set to the same level as the pressure applied to the ankle region of a normal sock. Also, the pressure in the convex calf region (see point c) can be set lower than in the region adjacent to the lower calf (see point b1). This setting provides the greatest compression control in the region adjacent to the lower calf (see point b1) in the longitudinal direction. In FIG. 2, the dotted lines are drawn schematically so that the spacing (density) in the horizontal direction represents the size of the mesh (part of the spacing in the horizontal direction is illustrated by arrows). An area drawn with a narrow interval indicates that the mesh is small (the pressure applied is large), and an area drawn so as to spread out indicates that the mesh is large (the pressure applied is small). Therefore, it can be seen that the density is the smallest in the region adjacent to the lower calf (see point b1) and the contact pressure is the highest.

An example concerning a specific knitting will be described. However, it goes without saying that the configuration of the present invention is not limited to the embodiment. For the knitting machine, a circular sock knitting machine or a stocking knitting machine can be used. The area below the calf adjacent area (see point b1) is knitted with plain knitting (zokki knitting with plating of front and back threads), knitting yarn is cotton 30/1 for front yarn and FTY 20/70 for back yarn was used. The area above the lower calf adjacent area (see point b1) is knitted with plain knitting. The knitting yarn is 30/1 cotton for the front yarn, 20/70 FTY for the back yarn, and DCY polyurethane 140D x cotton 60/1 x rubber yarn. 60/1 cotton was used. The stitches are made to gradually increase, for example, in a stepwise or tapered fashion, from the region adjacent to the lower calf (see point b1) downward, and similarly, from the region adjacent to the lower calf (see point b1) to the upper calf convexity. It is woven so that it becomes gradually larger, for example, in a stepwise or tapered manner toward the region (see point c) by fashioning or the like. The density of the mouth rubber region 30 is almost the same. As the material of the knitting yarn, other than those of the examples, natural materials such as hemp and wool, and chemical fibers such as rayon, nylon, acrylic and polyester can be used.
Table 1 shows the compression values at point b in the ankle area, point b1 in the area adjacent to the lower calf, and point c in the protruding area of the calf when wearing the compression socks.

(action/effect)
As described above, by controlling the pressure by adjusting the size of the mesh and the presence or absence of rubber thread, etc., the pressure is maximized in the area adjacent to the lower calf (see point b1) to ensure a support function that sends blood upward, and It has become possible to easily put on and take off by loosening the pressure on the narrow ankle region (see point b), which is the main cause of difficulty in putting on and taking off. By changing the eyes through fashion, it is possible to avoid problems caused by extreme changes. In addition, simply weakening the wearing pressure in the ankle region (see point b) may cause the fabric to become doweled, impairing ease of wear.
As a further effect, it has become possible to reduce the bite into the ankle area by applying pressure control that weakens the pressure on the ankle area. Also, if a natural material is used for the covering material of the knitting yarn, most of the parts that come into contact with the skin, such as the calves, become natural materials such as cotton, which reduces the burden on the skin and makes it possible to improve the texture. Furthermore, by not inserting the rubber thread in the foot region from the ankle region to the toe region, tightening of the foot portion when wearing is relaxed, and the effect of making it easier to put on and take off can be obtained.

[Second embodiment]
In the second embodiment, compared to the compression socks according to the first embodiment, the length of the apparent lateral dimension (width dimension) of the cuff region 30 when laid flat is that of the compression socks. It is the largest among them, and the configuration of inserting a rubber thread into the mouth rubber region 30 is added.
By having the rubber cuff region 30 having the above structure, it is possible to realize the function and effect that it is wide and loose and does not bite even when worn for a long time.

[Third embodiment]
In the third embodiment, a non-slip and durable material is added to the knitting yarn in a predetermined area of the foot area, compared to the compression socks according to the first and second embodiments. FIG. 3 is a schematic diagram showing the foot region of the compression sock according to the third embodiment worn on the foot.

In the example, the sole region 40, the toe region 50, and the heel region 60 as the predetermined regions were knitted by plain knitting, and the knitting yarn used was Japanese paper 1/38 for the front yarn and FTY 20/70 for the back yarn. . However, the predetermined area of the foot area may be any one of the above three areas, and the knitting thread may be made of polyurethane elastic thread, silicon thread, secant thread, etc., instead of Japanese paper thread, if necessary. good.
By knitting the predetermined area of the foot area with the above-described configuration, it is possible to obtain a non-slip property and further improve durability compared to ordinary cotton materials.

[Fourth embodiment]
The fourth embodiment is obtained by adding a configuration in which the peripheral region of the heel region 60 is knitted by rib knitting to the compression socks according to the first to third embodiments. FIG. 4 is a schematic diagram showing the foot region of the compression sock according to the fourth embodiment worn on the foot. As an example, the heel peripheral region 70 is knitted by rib knitting (zokki knitting of plating of front and back yarns), and knitting yarns are cotton 30/1 for the front yarn and FTY 20/70 for the back yarn. board.
By ribbing the heel peripheral region 70 to suppress elongation, it is possible to provide support around the heel and allow the heel to fit completely when worn, making it easier to wear.

[Fifth embodiment]
The fifth embodiment is obtained by adding a toothless (no toe) configuration to the compression socks according to the first to fourth embodiments.
