Description

[Technical field]

[0001] The present invention relates to footwear. [Background technology]

[0002] 2. Description of the Related Art Since blood circulation in the feet is prone to become poor, various proposals have been made to improve blood circulation in the feet and thereby promote health.

[0003] For example, Patent Document 1 proposes a sock in which numerous protrusions are formed on the inside of the sole, made of an elastic resin material, leaving the arch portion uncovered. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 9-95802 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the above socks have resin protrusions on the inside of the soles, and the protrusions are pressed against the soles of the feet by the wearer's own weight when walking, thereby promoting blood circulation. Therefore, the acupressure effect varies depending on the weight of the person wearing the socks, and for heavy people the acupressure effect from the protrusions may be too strong, causing pain in the soles of the feet, while for light people the acupressure effect from the protrusions is weak.

[0006] The present invention provides footwear that provides an excellent blood circulation improving effect for any wearer. [Means for solving the problem]

[0007] The footwear of the present invention is footwear to be worn on a wearer's foot, The device is characterized by comprising a heel attachment part for attaching to the heel of the wearer and containing a negative ion radioactive material that radiates negative ions, or a toe attachment part for attaching to the toe of the wearer and containing a far-infrared radiative material that radiates far-infrared rays. Effect of the Invention

[0008] The footwear of the present invention has a heel attachment part for attachment to the heel of a wearer and containing a negative ion radioactive material, or a toe attachment part for attachment to the toe of a wearer and containing a far-infrared radiative material.

[0009] When the footwear of the present invention has the above-mentioned heel attachment portion, it aims to promote blood flow by emitting negative ions emitted from a negative ion radioactive material to the blood flowing through the heel, and this increased blood flow in the heel also promotes blood flow in the blood vessels in the toe that are connected to the blood vessels in the heel.

[0010] In addition, when the footwear of the present invention has a toe attachment part that is attached to the toes of a wearer and contains a far-infrared emitting substance, the toe part is irradiated with far-infrared rays emitted from the far-infrared emitting substance, thereby promoting blood flow in the blood vessels in the toe part.

[0011] Furthermore, when the footwear of the present invention has a heel attachment section and a toe attachment section, the synergistic effect of the negative ion effect in the heel section and the far-infrared effect in the toe section can improve blood flow throughout the wearer's foot, allowing the wearer to more effectively enjoy health-promoting effects such as the alleviation of sensitivity to cold and the moisturizing effect on the skin due to the improved blood flow in the feet.

[0012] The footwear of the present invention aims to effectively improve blood flow by disposing a negative ion emitting material and a far-infrared emitting material in the heel and toe areas, which are subjected to the weight of the wearer's foot both when walking and standing, and which have a high degree of adhesion to the wearer's foot when worn. [Brief description of the drawings]

[0013] [Figure 1] 1 is a schematic diagram showing an example of footwear of the present invention. [Diagram 2] FIG. 4 is a cross-sectional view showing another example of footwear of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] An example of footwear of the present invention will be described with reference to the drawings. The footwear of the present invention is not particularly limited as long as it can be worn at least around the wearer's foot (the part below the ankle). Examples of footwear include socks, inner socks, tabi socks, indoor footwear, and portable footwear. In the following, socks will be used as an example for the description (see FIG. 1).

[0015] Sock A is usually made of elastic fibers and is worn covering at least the wearer's toes to the lower part of the ankle. Sock A contains a negative ion radioactive material in heel attachment part 1, which is worn around the heel of the wearer. Although the action of negative ions emitted from this negative ion radioactive material has not been clearly elucidated, they act on red blood cells in the blood flowing through the blood vessels in the heel of the wearer, negatively charging the red blood cells, and the electrical repulsion between these negative charges reduces the viscosity of the blood and promotes blood flow.

[0016] The negative ion radioactive material is not particularly limited as long as it can emit negative ions. The negative ion radioactive material has a negative ion density of 101×10 6 / m 3 More preferably, it is equal to or greater than this.

[0017] Examples of negative ion radioactive substances include tourmaline, which is called tourmaline, negative ion radioactive ceramics, samarskite, xenotime, variant zircon, trogomite, heergosonite, mosaniite, bastnasite, monazite, davidite, brannellite, uraninite, ningyoite, uraninite, carnotite, chamunite, metachamunite, fransevilleite, thorite, coffinite, thoriumite, and trogomite. The negative ion radioactive substances are preferably substances collected from nature. The negative ion radioactive substances may be used alone or in combination of two or more kinds.

[0018] In the heel attachment part 1 of the sock A, the content of the negative ion radioactive material is preferably 0.1 parts by mass or more, and more preferably 1 part by mass or more, per 100 parts by mass of the fiber that constitutes the heel attachment part 1. The content of the negative ion radioactive material is preferably 10 parts by mass or less, and more preferably 5 parts by mass or less, per 100 parts by mass of the fiber that constitutes the heel attachment part 1. If the content of the negative ion radioactive material is 0.1 parts by mass or more, the blood flow in the heel part of the wearer can be promoted. If the content of the negative ion radioactive material is 10 parts by mass or less, the wearability of the sock is not impaired, and this is preferable.

[0019] The sock A contains a far-infrared emitting material in the toe wearing section 2 that is worn by the wearer's toes. The far-infrared rays emitted from this far-infrared emitting material promote blood flow in blood vessels such as capillaries in the wearer's toes.

[0020] Sock A aims to improve blood flow not only in the toe area, but also in the heel area just before the toe area. By increasing blood flow throughout the entire foot of the wearer of Sock A, it synergistically improves blood flow in the toe area, where blood flow is prone to stagnation.

[0021] In addition, sock A uses different means, namely negative ions and far infrared rays, to improve blood flow in the heel and toe areas, and although it has not been clearly explained, it is believed to improve blood flow by irradiating red blood cells that have been negatively charged by negative ions with far infrared rays.

[0022] The far-infrared emitting material is not particularly limited as long as it can emit far-infrared rays. Examples of the far-infrared emitting material include minerals such as mica, talc, and calcite; oxide ceramics such as tin oxide, alumina, and silicon dioxide; carbide ceramics such as silicon carbide and boron carbide; platinum, tungsten, and the like. The far-infrared emitting material is preferably a material collected from nature. The far-infrared emitting material may be used alone or in combination of two or more kinds.

[0023] In the toe wearing part 2 of the sock A, the content of the far-infrared radiative substance is preferably 0.1 parts by mass or more, and more preferably 1 part by mass or more, per 100 parts by mass of the fiber constituting the toe wearing part 2. The content of the far-infrared radiative substance is preferably 10 parts by mass or less, and more preferably 5 parts by mass or less, per 100 parts by mass of the fiber constituting the toe wearing part 2. When the content of the far-infrared radiative substance is 0.1 parts by mass or more, the blood flow in the toes of the wearer can be promoted. When the content of the far-infrared radiative substance is 10 parts by mass or less, it is preferable since it does not impair the wearability of the sock.

[0024] A general-purpose method can be used to make the heel attachment part 1 and the toe attachment part 2 of the sock A contain a negative ion radioactive material and a far-infrared radiative material (hereinafter, sometimes collectively referred to as "radioactive material"). Examples of the method for making the heel attachment part 1 and the toe attachment part 2 of the sock A contain a radioactive material include (1) a method of attaching and integrating a radioactive material to the surface of the fiber constituting the sock using a binder (e.g., adhesive, synthetic resin, etc.), (2) a method of mixing a radioactive material (preferably a powdered radioactive material) into a monomer that is a raw material for the synthetic fiber, polymerizing the monomer to produce a synthetic resin, using this synthetic resin as a raw material to produce a synthetic fiber containing a radioactive material, and using this synthetic fiber to produce socks, and (3) a method of mixing a radioactive material into a synthetic resin that is a raw material for the synthetic fiber, using the synthetic resin containing a radioactive material as a raw material to produce a synthetic fiber, and using this synthetic fiber to produce socks. Although the above description has been given using the example of manufacturing socks, the present invention can also be applied to cases where radioactive material is contained in the heel attachment part and the toe attachment part of footwear other than socks.

[0025] The sock A is worn by the wearer in the same manner as usual, and emits negative ions to the heels and far infrared rays to the toes of the wearer without causing any discomfort to the wearer, thereby improving the blood flow in the entire foot, especially the toes.

[0026] In the above, socks A have been described as an example of footwear, but as mentioned above, the footwear is not limited to socks A and may be footwear such as that shown in FIG.

[0027] 2 is indoor footwear B, which has a footwear body B1 on which a wearer's foot can be attached. The footwear body B1 is deformable to follow the wearer's walking motion, is made of general-purpose materials such as fiber and synthetic resin, has a shape similar to that of a low shoe, and has a foot attachment part B11 into which the foot is inserted to cover the entire foot.

[0028] On the inner bottom surface of the foot attachment part B11 of the footwear body B1, a heel side storage part B12 is formed in the heel attachment part 1 on which the heel of the wearer is attached, and a toe side storage part B13 is formed in the toe attachment part 2 on which the toe of the wearer is attached. A negative ion emitting foam sheet C containing a negative ion radioactive substance is stored in the heel side storage part B12. A far-infrared emitting foam sheet D containing a far-infrared emitting substance is stored in the toe side storage part B13. The negative ion radioactive substance and the far-infrared emitting substance are the same as those described above.

[0029] The method of incorporating a radioactive substance into a foamed sheet can be a commonly used method, and examples of the method include (1) a method of mixing a radioactive substance into a paint and applying the paint containing the radioactive substance to the surface of a foamed sheet, and (2) a method of incorporating a radioactive substance into a synthetic resin that is the raw material of the foamed sheet, and then foaming this synthetic resin in a commonly used method to produce a foamed sheet, etc. The synthetic resin that constitutes the foamed sheet is not particularly limited, and examples of the synthetic resin that can be used include polyolefins such as polyethylene and polypropylene, synthetic resins such as polyurethane and polyvinyl chloride, and thermoplastic elastomers.

[0030] Like sock A, indoor footwear B can be worn by the wearer in the same manner as normal, and can radiate negative ions to the heels and far infrared rays to the toes of the wearer without causing any discomfort to the wearer, thereby improving blood flow throughout the wearer's feet, especially in the toes.

[0031] Although the above-mentioned footwear A has been described as having both a heel attachment part and a toe attachment part, the footwear A of the present invention may have only either the heel attachment part 1 or the toe attachment part 2. Furthermore, the footwear A may contain either or both of a negative ion emitting material and a far-infrared emitting material in parts other than the heel attachment part 1 and the toe attachment part 2.
