Abstract
Description
[Technical field]
[0001] The feet support the torso, but the balance between the sole of the foot and the ankle joint is especially important. Shoes are generally selected based on the length and size of the sole of the foot, but shoe stores measure where the center of gravity of the torso is located and select shoes based on that.
[0002] In addition, sports specialty stores will recommend shoes that are suitable for each sport, as different muscles are moved depending on the sport.
[0003] However, the primary consideration is probably the shape of the shoes we wear in our daily lives. However, there are many cases where the foot itself is abnormal due to deformation of the trunk.
[0004] The basis of bodywork is to pattern these peculiar shapes. The following is an excerpt from "Introduction to Bodywork for Beauty," published by Natsume Publishing and supervised by Tomoki Miyaguni and edited by Hisazo Sato.
[0005] The twelve types of corrective body types devised by Dr. Kamei Nissin have a direct effect on the foot, with 1. the brain type positive F1, 2. the digestive type positive F3, negative F4, 3. the urinary type positive F5, negative F6, and the rib type negative F7 directly affecting the ankle joint.
[0006] In his book, he states that the state of corrected posture is the correction of the vertebrae related to the "basic movements" of the human body - forward and backward, left and right, and rotation - and that it also aims to balance and adjust the internal organs. He believes that this is based on the idea of meridians in Oriental medicine, and that the shape of the feet also plays a major role.
[0007] Based on the above concept, looking at the shape of the feet from the perspective of Oriental medicine, the meridians of the spleen, liver and kidney organs originate from the toes and belong to the organs, so it also leads to judging the state of the organs. Conversely, adjusting the feet adjusts posture, and adjusting posture affects the organs, so we focus on creating a supporter that covers the meridians of the spleen, liver and kidney organs that originate from the feet. Adjusting the feet adjusts the deformed body as mentioned above, and consider the composition based on that concept.
[0008] Because the supporter becomes a part of your body, your appearance will change over time, and as your appearance changes, the supporter will need to be changed as well.
[0009] The diagnosis technique of the above-mentioned osteopathic treatment is the secret of medicine, and is not easy. Depending on where the center of gravity is, the size of the left and right legs and the thickness of the left and right ankles will differ. The living body is intricately intertwined, and it is not possible to clearly separate the twelve body types. In other words, the twelve body types themselves are complex. Ultimately, everyone needs a support that is suitable for everyone, and I believe that insoles are necessary for the soles of the feet.
[0010] To devise a supporter for ankle joints, which can transfer a propulsive force transmitted from the big toe through the sole to the leg through the ankle joint without reducing the propulsive force, by focusing on protecting the ankle joints and allowing the ankle joints to fully function when making the supporter for the ankle joints.

[0011] [Patent Document 1] Patent Publication No. 2003-299684 [Patent Document 2] Patent Publication 2009-50418 [Patent Document 3] Patent Publication No. 2006-305209 [Patent Document 4] Patent Publication No. 2004-357791 Summary of the Invention [Problem to be solved by the invention]
[0012] As mentioned above, it is difficult to make a ready-made product that suits everyone, so we aim to create a basic supporter.
[0013] The primary purpose of a support is to protect the ankle joint. I often hear people who play sports complaining that the big toe of their socks always gets holes, and asking if there are socks that don't get holes. I think this is due to strong wear rather than forcing the big toe to pivot. I believe this is not only caused by people with a tendency for valgus foot, but also by the fact that the axis of the torso differs slightly depending on the type of sport. The protective effect of a support can be increased by using cushioned materials for the pivot part, or abrasion-resistant materials such as double russell or polyurethane. This is why I think the choice of material is important.
[0014] The second purpose of the supporter is to enhance the body's functions. In traditional Chinese medicine, three meridians originate from the big toe: the spleen, liver, and kidney meridians, and flow toward each organ. Extreme pressure or physical injury can damage the meridian flow, while moderate stimulation can activate the meridian flow by overlapping with blood circulation.
[0015] Considering meridian infusion requires observational skills that include the complex intertwining of organs, so it must be considered only in basic terms. Those caused by visceral disease require consideration with specialized knowledge. The human body has a cybernetics that allows it to regenerate itself, so it takes a long time to develop visceral disease. Also, by taking preventative measures before visceral disease develops, it is possible to prevent the disease from becoming serious. In particular, in the case of diabetes, the big toe hurts, making it difficult to exert force on it.
[0016] The third purpose of the supporter is to correct the posture. Correcting the legs is correcting the trunk and adjusting the whole body, so even if you can adjust only that part to the correct position temporarily, if you do not correct it from the root, it will return to the original position soon.
[0017] The purpose of the supporter is clarified before selecting the type of supporter, but the goal is to create a supporter that has as many benefits as possible in as many situations as possible. Of course, the same goes for sports supports, and it is best to have one that also provides health management. A supporter with good muscle and skeletal structure is a healthy supporter.
[0018] Supporters use Oriental medicine insight to understand the flow of meridians and physically elucidate their role. The three meridians originating from the big toe are all Yin meridians, and control the vitality of the human body. The three meridians originate from the big toe, which means that they are the source of Qi and blood. The Yin meridians all flow toward the organs, obtain the organ's blood supply, and connect to the Yang meridians, which then appear as a phenomenon in the body.
[0019] Let's look at the flow of the Taiyin Spleen meridian, one of the three meridians, with reference to Figure 1. If we plot the flow of acupoints from where the Taiyin Spleen meridian originates to the ankle, it is as follows: 1. Yinbai point, 2. Dadu point, 3. Taibai point, 4. Gongsun point, 5. Shangqiu point, 6. Sanyinjiao point. According to a menstrual blood map taken from reference material, on the body surface, it runs along the anterior edge of the inner lower leg and the front of the trunk, and is used to treat sensory and motor disorders of the inner lower leg and digestive system, improve malnutrition and chronic fatigue, and treat gynecological diseases. It is involved in the treatment of spleen deficiency syndrome.
[0020] Let's look at the flow of the two Jueyin Liver meridians, which are one of the three meridians, with reference to Figure 2. If we plot the flow of acupoints from the location where the Jueyin Liver meridian originates to the ankle, we get 7 Dadun point, 8 Xingjian point, 9 Taichong point, 10 Zhongfu point, and 11 Liguo point. According to a menstrual blood map taken from reference material, on the body surface, it passes through the inside of the dorsum of the foot, the middle of the inside of the lower leg, and the side of the abdomen, and is used to treat sensory and motor disorders of the dorsum of the foot and the inside of the lower leg, as well as reproductive system and gynecological disorders. It is involved in the treatment of Liver deficiency syndrome.
[0021] The flow of the three Shaoyin Kidney meridians of the three meridians can be seen in Figure 3. If we plot the flow of the acupoints from the origin of the Shaoyin Kidney meridian to the ankle, we get 12 Yongquan, 13 Rangu, 14 Taixi, 15 Dazhong, 16 Shuiquan, 17 Zhaohai, 18 Fuliu, 19 Gongshan, and 20 Zhubin. According to a menstrual blood map taken from a reference material, on the body surface, it runs along the soles of the feet, the lower legs, and the front of the trunk, and is used to treat sensory and motor disorders of the soles of the feet, as well as urinary, reproductive, endocrine, and gynecological disorders. It is involved in the treatment of kidney deficiency syndrome.
[0022] As mentioned above, it is clear that the three meridians above originate from the area centered on the big toe. In the general theory of acupoints, the qi and blood of the meridians do not occur anywhere other than the big toe side of the foot. By generating qi and blood in the area centered on the big toe, the role of the inside of the foot and the ankle joint is understood, and the flow of qi and blood is adjusted accordingly.
[0023] The Qi of Qi and Blood has the property of rising upwards, but when it is accompanied by blood, gravity is applied, so if the propulsive force of Qi weakens, the Qi and Blood cannot rise properly. In meridian infusion, it is the muscles that increase the flow of Qi and Blood, and the muscles are attached to the bones and their movement is strengthened by the joints. In particular, in the ankle joint, centered around the big toe, the movement of the joints activates the movement of Qi and Blood. In other words, when the toes move, the arch of the foot acts as a spring to transmit power to the ankle joint, and the meridian infusion, which is the flow of Qi and Blood, begins to work.
[0024] The challenge is to create a supporter that enhances the function of the muscles on the inside of the thumb and the medial malleolus side of the ankle joint. As for the other toes, they are yang meridians, and since gravity is received from the top to the bottom and qi and blood return, muscle mass as large as that of the thumb is not necessary. A supporter that allows qi and blood to flow smoothly by relaxing the space between the toes and not blocking the flow of qi and blood by compressing them will suffice.
[0025] The most important thing is the flow of the Shaoyin-Yin Kidney Meridian in Figure 3. The supporter is centered on the Shaoyin Kidney Meridian, and the flow of the Shaoyin Kidney Meridian is the key. The kidney meridian follows a loop at the lower part of the inner ankle. This is because the flow of the kidney meridian originates from the sole of the arch and reaches the lower part of the inner ankle, transmitting the force of bending the ankle joint. When the spring force of the sole of the foot is not sufficient, the qi and blood of the kidney meridian stagnates. Looking at the flow of the kidney meridian, the meridian flow temporarily drops from top to bottom at the lower part of the inner ankle, then rises again. It can be understood that the force of pulling the qi and blood upwards is added by using gravity to drop the meridian flow downward once. This is aimed at the effect of gravity and leverage, and shows how important the role of the lower part of the inner ankle is. As an aside, this principle of leverage is the same as the method of lifting Qi and blood at the side of the Shaoyang Gallbladder meridian in meridian infusion, where the infusion is dropped and then the recoil is used to lift Qi and blood again. The method of lifting Qi and blood is also used in Yin meridian infusion. The method of lifting Qi and blood is only used in a few places in all meridian infusions, and the loop-shaped infusion is only at the inner ankle of the Kidney meridian of the Yin meridian, so you can see how the loop shape of the inner ankle is the most important thing for the ankle joint. Therefore, there are various theories about the infusion of the Kidney meridian in past interpretation books. In the case of valgus foot, it can be understood that the arch is not fully developed, resulting in flat feet and putting strain on the ankle joint.
[0026] When using a supporter, it is important that it fits well against the skin, as the supporter is a method of increasing the flow of qi and blood, mainly through the kidney meridian. The muscles in the joints have the role of transmitting the power of the toes through the supporter, adding pressure, so it is preferable for the supporter to be one that adheres tightly to the skin and stretches.
[0027] Since the goal is to guide qi and blood, it is effective to use pressure or magnetism, or to insert magnets or magnetic tape into the meridian infusion.
[0028] In addition to the acupuncture points of the normal meridians mentioned above, there are also special acupuncture points. Please refer to "Figure 4" to see the list. There are 21 Shixuan, 22 Bafeng, 23 Lineiting, 24 Nei Zhao Jing, 25 Heping, 26 Shangxi, and 27 Hepatitis. Using the power of special acupuncture points can also be effective.
[0029] The areas of the thumb where pressure is applied are the nail, the space between the toes, and the ball of the foot. Although there are no acupressure points on the pad of the big toe, there is a lot of pressure around the nail of the thumb.
[0030] Neurologically, the big toe side is in the lumbar plexus, and is in the area controlled by the fifth lumbar nerve. On the sole of the foot, the area is divided into the sacral nerve area at the Yongquan point, as shown in the figure. See figures 5 and 6. The big toe side is sympathetic, while the other toes have increased parasympathetic elements. Therefore, it is understandable that stimulation is stronger on the big toe side. [Means for solving the problem]
[0031] The big toe is covered by a thumb covering part A, and on the instep side, a foot covering part B extends from the base of the thumb through the instep to the instep and medial ankle. On the sole of the foot of the thumb covering part, a sole covering part C extends from the base of the thumb through the Yongquan point on the sole, through the Moenya point on the arch on the inside before the ankle, and to just before the medial ankle. The instep covering part B and the sole covering part C are connected up to just before the ankle on the instep, but are divided into two just before the medial ankle X, and each has an extension part. The second extension part CE is an extension part from the sole covering part, and the first extension part BE is an extension part from the instep covering part B. The second extension part CE and the first extension part BE are hooked onto the medial ankle protuberance X for fixation by sandwiching it therebetween, and the respective extension parts are as follows: A hole is made in the medial malleolus protuberance, and the sole cover part CE, which covers the inside of the ankle, passes through the medial malleolus X, and then wraps around the top of the ankle from the inside of the ankle, around the Achilles tendon on the sole of the ankle, and reaches the front of the ankle, and the instep cover part BE covers the medial malleolus protuberance at the medial malleolus X, crosses the sole cover part CE, and wraps around the sole of the ankle, and is again connected and fixed by a hook-and-loop fastener at the front of the ankle at the sole cover part CE. A magnet Z is placed in a predetermined hole in the supporter, and the magnetic foot supporter is wrapped around the ankle from the big toe to the instep, sole, and medial malleolus (see Figs. 1 and 8).
[0032] The spleen, liver, and kidney supporter covers the inflow of the three meridians, the spleen meridian, the liver meridian, and the kidney meridian, and is a supporter intended to affect the feet to the internal organs and from the internal organs to the feet. The supporter connects the big toe to the ankle joint, fixes the ankle, and can be further strengthened by wrapping a magnetic material around the meridian inflow and inserting a magnet into a designated hole inside.
[0033] The big toe covering part A completely covers the big toe from the tip of the big toe, and the big toe covering part includes the Yinbai point 1, the Dadun point 7, the Shixuan point 21, and the Bafu point 22 as shown in Figure 7. The Shixuan point in particular is the part that causes throbbing pain in diabetes. This is because the Spleen meridian and the Liver meridian are deeply involved in diabetes.
[0034] Since strong force is applied to the pad of the big toe, the pad is protected by a cushioned polyester double russell or urethane material. This is especially necessary when playing sports that subject the big toe to twisting force.
[0035] The 21 Shishun and 22 Happu points on the big toe are effective for vascular disorders, so magnetic material is inserted into them.
[0036] Part B of the instep covering part extends from the base of the big toe through the instep to the instep and inner ankle; and on the sole side of the part B of the big toe covering part, part C of the sole of the foot extends from the base of the big toe through the Yongquan point 12 on the sole of the foot to the Mengani point on the arch just before the ankle joint. Part B of the instep covering part and part C of the sole of the foot separate at the top of the Mengani point 13, and the extension part extends and covers part of the inside of the ankle joint, and part CE of the sole covering part extends from the bottom of the inner ankle X to cover the entire inside of the heel and connects to the ankle.
[0037] The supporter is divided into sections A, B, and C, and the lines drawn along the sections are on each of the meridians. As these lines are in areas where strong currents flow, it is a good idea to stimulate them by sticking linear magic sheets or magnetic silicone onto the supporter.
[0038] The sole cover part and the instep cover part are joined by a sole cover part CE, which is a part excluding the medial malleolus X part on the inside of the ankle, which is separated from the medial malleolus, crossing the instep cover part BE, passing from the upper part of the lateral malleolus Y on the outside of the ankle through the Achilles tendon, and wrapping around the ankle to be fixed. The instep cover part BE goes around the Achilles tendon from the medial malleolus X, passes through the upper part of the lateral malleolus Y, and comes out on the front of the ankle, and is joined to the sole cover part CE and fixed with a hook-and-loop fastener D.
[0039] The ankle is connected to the three Yin meridians mentioned above and the three Yang meridians that end in the toes other than the big toe. It is also important to balance Yin and Yang at the ankle, and this ankle band binds a total of six meridians that flow through the foot.
[0040] This supporter extends from the sole of the foot covering the inside of the ankle joint, covers the area around the medial malleolus, goes up to the top of the medial malleolus and then transitions to the ankle, improving the connection between the ankle and big toe and making it possible to effectively transmit and synchronize the power from the big toe to the ankle.
[0041] Sole cover part C, which covers the inside of the ankle joint, and instep cover part B cross over at the front of the ankle joint and move in the opposite direction, fitting the supporter to the ankle while tightening it up and supporting the ankle joint. Furthermore, the sole cover part CE goes around the Achilles tendon and returns to the ankle above the medial malleolus. Instep cover part BE passes around the medial side of the ankle joint, goes around the Achilles tendon, passes above the lateral malleolus, and returns to the ankle, integrating the instep cover part BE and the sole cover part CE.
[0042] The basic structure consists of a thumb cover A that covers the big toe, an instep cover B on the instep side that runs from the base of the thumb through the instep to the instep and medial ankle, and a sole cover C on the sole side of the thumb cover that runs from the base of the thumb through the Yongquan point on the sole to the Moenya point on the arch just before the ankle joint on the inside. The instep cover extension BE and sole cover extension CE are supports that are wrapped around the ankle at the ankle joint and secured in place D with a hook-and-loop fastener, and for the purpose of magnetic guidance, it is also possible to place magnets in the designated holes or to attach magnetic sheets in certain areas, or to use an elastic material such as magnetic rubber for the supporter material. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0043] The thumb cover A covering the big toe is made up of an instep cover B on the instep side, which extends from the base of the thumb through the instep to the instep and the medial malleolus, and a sole cover C on the sole side of the thumb cover, which extends from the base of the thumb through the Yongquan point on the sole to the Moenya point on the arch of the foot on the inside just before the ankle. The instep cover and the sole cover are connected up to just before the ankle on the instep, but are split into two just before the medial malleolus X, and the extensions are extended to hook the extension CE of the sole cover and the extension BE of the instep cover onto the medial malleolus protuberance X for fixation. While removing the medial malleolus protuberance, the sole covering part CE, which covers the inside of the ankle, passes through the medial malleolus X and is then wrapped around the inside of the ankle and the upper part of the ankle at the front, wraps around the Achilles tendon at the bottom of the ankle and reaches the front of the ankle, and the instep covering part BE removes the medial malleolus protuberance X at the medial malleolus, crosses the sole covering part, wraps around the sole of the ankle, and connects with the sole covering part CE at the front of the ankle and is fixed with a hook-and-loop fastener D. This completes the magnetic foot supporter that links the ankle, ankle and big toe and balances the entire foot by placing magnets in the designated holes.
[0044] The spleen, liver, and kidney meridians, which originate from the big toe, belong to the organs and circulate throughout the body via the bowels. These three meridians are the origin of the yin meridians and act as their command center.
[0045] As mentioned above, the ankle joint is considered to be the center of the meridians, so the basic principle of foot supports is to achieve basic balance by strengthening and adjusting the ankle joint.
[0046] In the technical field, we have listed the twelve types of body types proposed by Professor Kamei Nisshin, and we wondered if we could create a supporter that could simultaneously address abnormalities caused by front-back, left-right, and twisting of the body. However, instead of only capturing the current state of the abnormalities in the twelve types of body types, we focused on a method of gradually correcting the cause from the basic structure, and thought that it could be an effective supporter that anyone could wear by adjusting the ankle joint.
[0047] From the above idea, we focused on the big toe and aimed to create a supporter based on the theory of Oriental medicine that is suitable for everyone, which is fitted to the big toe, runs from the instep from the big toe and the sole from the big toe around the medial malleolus to the ankle joint, and is wrapped around the ankle.
[0048] This support is often thought to be important only for the big toe, but it is also important to support the other fingers, and for the other fingers, it is necessary to have a relaxed position for each finger, and insoles and shoes that do not tighten the fingers are essential. In Oriental medicine, the fingers other than the big toe are considered to be the parts where qi and blood return from the whole body in the yang meridian flow, so other than the thumb, it is generally combined with a method that does not tighten. EXAMPLES
[0049] A thumb cover part A covering the big toe transitions to an instep cover part B that connects from the base of the thumb to the instep side, and the sole side of the base of the thumb of said thumb cover part A is a sole cover part C that passes through the Yongquan point on the sole and covers the Mengya point behind the arch of the foot on the inside before the ankle, and said instep cover part and said sole cover part C are joined at the ankle of the instep part, but said sole cover part C is connected to the medial ankle that covers the inside of the ankle joint, and further branched out on the inside of the ankle to give each an extension part, and both extension parts are crossed from both sides in opposite directions and wrapped around the upper part of the ankle to fix it, characterized in that the spleen-liver-kidney foot supporter from the thumb to the instep, medial ankle and ankle is characterized in that
[0050] It can be used for all general organ diseases as a medical treatment. For diabetes, it is considered to be a comprehensive disease of the spleen, liver, and kidneys. When pain occurs in the big toe, the spleen meridian's yin deficiency syndrome has already begun. If you refer to the diagram, it affects all the acupoints on this supporter, so it is a good idea to make it with materials that are magnetic overall. In addition, the acupoints that should be especially placed with magnets are Yongquan point 12, Shixuan point 21, Bafu point 22, Sanyinjiao 6, Taixi point 14, Xingjian point 8, and Dadun point 1. It is effective not only for serious diseases such as lower back pain derived from diabetes, urinary system diseases, reproductive diseases, mental diseases, liver and kidney organ diseases themselves, and eye diseases, but also for minor fatigue.
[0051] In addition, by widening the area wrapped around the ankle to 6 cm or more and inserting magnets into the designated holes, the range of treatment can be expanded.
[0052] In severe cases, it is a good idea to insert a flat magnet wrapped in cushioning material into the sole of the foot, especially at the Yongquan point 12 and the surrounding arch. EXAMPLES
[0053] For sports, it is best to pay attention to the material of the supporter. It is best to use a thin, stretchy material, and do not use magnets or other uneven surfaces. It is effective to use a material that contains magnetic material, and the material for the sole cover should be particularly elastic.
[0054] Supports that focus on the big toe and inside of the foot have cushioning materials such as polyester double russell and urethane attached to the area that is under pressure on the side of the big toe.
[0055] The other toes are important for balancing the big toe, so they need to be loose to some extent, and you should be careful when choosing shoes. Also, by putting a thick material in the arch area of the insole of the shoe, you can support the arch and adjust the position of the center of gravity depending on the sport.
[0056] The width of the part that wraps around the ankle should be about 3 to 5 centimeters. [Brief description of the drawings]
