Description

The present invention relates to socks having legs extending to the bulging shin, that is, high socks, for improving blood circulation.

As shown in FIG. 4, the circulatory system responsible for blood circulation is composed of a heart, arteries, arterioles, capillaries, venules, and veins. In this circulatory system, the oxygen-rich blood returned from the lungs is carried throughout the body by arteries, and the peripheral arteries gradually become thinner (become arterioles) and become capillaries. Capillaries are a place for substance exchange between blood and interstitial fluid (tissue fluid), and when oxygen and nutrients have been delivered, carbon dioxide, waste products, excess water, etc. are collected (filtration and re-filtration of water, etc.). Absorption takes place). Capillaries gradually gather into thick venules and veins, which allow blood to return to the heart.

In this blood circulation, the amount of water filtered and the amount of water reabsorbed are not the same, and some water remains in the tissue fluid without being reabsorbed. It is the lymphatic vessels (system) that collect this remaining water (tissue fluid), and the capillary lymphatic vessels of that system also gradually gather, gathering through the lymph nodes (lymphatic vessels) to become the lymphatic trunk, and the base of the neck. Pour into the lymph at.

Also, in this blood circulation, the amount of blood flowing through the arteries and the amount of blood flowing through the veins are not the same, and the walls of the arteries are thick and have little extensibility, whereas the walls of the veins are thin and easy to extend. By widening the walls of the veins, the veins contain four times as much blood as the blood flowing through the arteries.
At this time, the blood and lymph below the heart do not have a strong pump like the heart, so in order for the blood and lymph in the veins that tend to collect to return to the heart, support for returning is required. Is.
For this reason, veins and lymph vessels have a large number of valves to prevent the once-raised blood and lymph from flowing back (see FIG. 5).

However, in order to push up blood and lymph, a force for that purpose is required, and the movement of muscles is the force in the upper and lower limbs. Furthermore, in the upper and lower limbs, veins and lymph vessels often pass between the skin and muscles, so it is necessary for circulation to firmly transmit the movement of muscles to the veins and lymph vessels.
That is, the blood that flows to the legs returns to the heart against gravity, so the bulging shin muscles act as a pump to help blood circulation. As much as 70% of the blood is collected in the lower body of a human being, and the bulging shin works to return this blood to the heart, so it is also called the "second heart". Muscle contraction is required for the pump to work, and by supporting muscle movement, it helps circulation (see FIG. 5).

Here, in the lymphatic system, if water does not collect and flows in the tissue fluid during the filtration (the part ○ in FIG. 4), the water will not be collected. "Swelling" of the lymphatic trunk and lymph vessels is caused by the accumulation of water in the tissue fluid that could not be collected by the capillaries or lymph vessels.

Based on the cause of such "swelling", a leg supporter consisting of a tubular upper supporter body that covers and tightens the bulging shin and a tubular lower supporter body that covers and tightens the arch of the foot has been proposed. (See Patent Document 1, Abstract, Claims 1, 2, etc.). In this leg supporter, the upper supporter body tightens the bulging shin with strong pressure at the central part in the vertical direction, tightens the bulging shin with weak pressure at both ends, and the part between the central part and both ends bulges. The shin is tightened with a medium pressure, and the lower supporter body tightens the arch of the foot with a strong pressure (see FIG. 1 of Patent Document 1).

Japanese Unexamined Patent Publication No. 11-131303

The sock made of the conventional leg supporter is a "stepped pressure" in which a weak pressure, a medium pressure, a strong pressure, a medium pressure, and a weak pressure are gradually applied from the lower side to the upper side of the bulging shin (Patent Document). 1 See FIG. 1). In this step compression, a force is applied in the direction orthogonal to the axis of the lower leg of the lower limbs, so only the muscles of the bulging shin (such as the triceps surae muscle) are compressed toward the axis, and blood is mainly lowered. The main action is to close the valve (prevention of backflow) so that it does not fall (to prevent it from returning), and the sufficient pumping action that serves as the second heart is not performed.
In addition, as shown in FIG. 6, socks (high socks) in which the tightening pressure is gradually reduced from the ankle to below the knee (see the arrow) have also been proposed. Yes, the sufficient pumping action is not performed.
Further, as in the case of the bulging shin, the sock applies an inward force over the entire circumference from the arch to the instep of the arch, and the massage effect of the arch is weak.

The first object of the present invention is to improve the pumping action, and the second object is to improve the massage effect of the arch.

In order to achieve the first task, the present invention has been made to be a "lifting compression" that lifts and tightens the muscles of the bulging shin.
When the bulging shin muscle is lifted and tightened, as shown by the arrow in Fig. 2, the muscle contraction is performed diagonally upward, so in addition to the force to contract the veins and lymph vessels, the central side (heart) The force that pushes toward the side) acts. Since this pushing force is in the direction of returning blood, the pumping action is improved.

Specifically, the present invention is a high socks having a foot portion attached to a foot, a leg portion attached to a lower leg, and a rubber mouth portion, and a portion covering the bulging shin of the leg portion. The bulging shin lifting region in the diagonal direction toward the rubber mouth portion was formed on both outer sides in the longitudinal direction from the middle of the width direction.
The bulging shin lifting region can have a plurality of radial streaks toward the mouth rubber portion. With this muscle shape, the lifting effect of the bulging shin is improved.
In this configuration, in the case of high socks having an arch portion on the foot portion, if a lifting area is formed from the arch portion toward the instep portion, a force from the bottom to the top acts on the arch portion to form the arch. You can massage. That is, the second task can be achieved.

According to the present invention, the high socks are configured as described above to provide "lifting pressure" for lifting and tightening the muscles of the bulging shin, so that the pumping action in the lower limbs is improved and swelling is less likely to occur.

An embodiment of the high socks according to the present invention is shown, (a) is a front view for the left foot, and (b) is a back view of the same.

An embodiment of a high sock (sock) according to the present invention is shown in FIGS. 1 and 2. The high socks P have a foot portion 1 attached to a foot, a leg portion 2 attached to a lower leg, and a rubber mouth portion 3. The main part A is formed by ordinary circular knitting, flat knitting, rubber knitting, or the like, and a part (diagonal line part) B is tack-knitted. The degree of pressure (rubber pressure) of the mouth rubber portion 3 is set to "weakest" as long as it can withstand use.

The part B forms an oblique bulging shin lifting region toward the mouth rubber portion 3 from the middle of the width direction to both outer sides of the portion 2a covering the bulging shin of the leg portion 2 in the longitudinal direction. It is configured.
The shape of this part (bulging shin lifting region) B is arbitrary as long as it becomes a "lifting pressure" that lifts and tightens the bulging shin muscle. For example, in FIG. 1, three diagonally radial streaks (b) are formed on the front and back surfaces, and the streaks (b) are subjected to experiments so as to optimally obtain the bulging shin lifting effect. Depending on the number, one, two, or four or more are optional.

In this embodiment, a part (bulging shin lifting area) B is, for example, a knitting method (tuck knitting) in which one stitch is knitted and then the third stitch is knitted without knitting in the rubber knitting forming the main part A. Is repeated, and the portion B is contracted in the knitting direction to produce a pulling effect in the vertical direction (vertical direction in FIG. 1). Further, a part B thereof can be knitted with a thread having a different color from that of the main part A.

Further, a lifting area B is formed from the arch portion 4 toward the instep portion, and a force from the bottom to the top acts on the arch portion (to achieve a vertical lifting effect) to massage the arch portion 4. .. Therefore, in this embodiment, the ankle portion having the strongest pressure (pressing) in the conventional high socks (socks) with stepped pressure is in a pressure-free state, which is almost the same as that of the normal socks.

The high socks of this embodiment have the above configuration, and as shown in FIG. 2, when the knee-high socks are worn and walked in the same manner as usual, a vertical pulling action is performed in the bulging shin lifting region B as shown by an arrow. , The muscle contraction (muscle contraction) action shown in FIG. 5 is assisted (supported). Therefore, the pumping action due to the contraction of the muscle is supported (assisted), the circulation of veins and lymph fluid becomes smooth, the collection of waste products and excess water becomes smooth, and the occurrence of "swelling" is suppressed.
Further, also in the arch portion 4, the pulling action is performed without pressing the instep portion, and the massage effect is improved.

In this embodiment, for example, the pressure (pressing) of the bulging shin lifting area B is 22 hpa for women, the pressure of the ankle portion is 10 hpa, and the bulging shin lifting area B is for men. Pressure: 27hpa, Ankle pressure: 10hpa, for men's sports pile
The pressure of the bulging shin lifting area B is 22 hpa and the pressure of the ankle portion is 6 hpa, or the pressure of the bulging shin lifting area B is 28 hpa and the pressure of the ankle portion is 7 hpa. As described above, in this embodiment, the bulging shin portion has a strong pressure (pressing, compression) of 22 to 28 hpa, whereas the ankle portion having the highest pressure in the step compression socks is another normal sock. It is a pressure-free state with almost no difference.

The embodiment is a sock having a toe portion (high socks), but if the leg portion 2 is a sock that extends from the ankle to below the knee and covers the shin, for example, the lower leg portion (leg) from the ankle to the knee. Of course, it can also be used for the ones only in Part 2) and the toeless socks P'shown in FIG. In this toeless sock P', the degree of pressure (rubber pressure) between the mouth rubber portion 3 and the other rubber portion 3a can be set to "weakest" as long as it can withstand use.
Although FIG. 3 shows the front surface for the left foot, the back surface has a symmetrical shape with that of FIG. Further, although FIGS. 1 and 3 show for the left foot, it is needless to say that they are manufactured in pairs, and it is preferable to make the "lifting compression socks" for the left and right feet symmetrically (the front and back sides of FIG. 1 are reversed). ..
Thus, the embodiments disclosed this time should be considered to be exemplary in all respects and not restrictive. The scope of the present invention is indicated by the claims and is intended to include all modifications within the meaning and scope equivalent to the claims.
