Description

  The present invention relates to an insole for a shoe that can suppress the propagation of germs and the generation of odors inside the shoe.

  For example, if a shoe is worn for a long period of time, the humidity inside the shoe increases due to sweat or the like, so that germs are likely to propagate, and a smell due to the germs is generated inside the shoe. Therefore, conventionally, for example, a shoe insole that removes the odor generated inside the shoe using the deodorizing action of activated carbon has been used (see, for example, Patent Document 1). The insole of the shoe includes an insole body composed of a main body member and a front member that covers one side of the main body member. Between the main body member and the front member, powdered activated carbon is provided. The mixed nonwoven fabric sheet member is interposed. Since the activated carbon has a deodorizing action for adsorbing odors, the odor generated inside the shoe by the deodorizing action of the activated carbon is removed by placing this insole on the inner bottom of the shoe.

Yes. Since the cloth member or the resin member can be cut freely, the insole 2 of various sizes can be easily obtained by cutting the main body member 4 into an appropriate shape.

  The front member 6 is made of a sheet-like tatami surface material, and the outer shape thereof is substantially the same as the outer shape of the main body member 4. The tatami surface material is formed by weaving a large number of cocoon grass materials as required, and a slight gap is formed between the cocoon grass materials and the cocoon grass material. As a result, ionized antibacterial metal 14, that is, silver ions 24 and / or copper ions 26 pass through these gaps, as will be described later.

  The sheet member 10 is configured in a rectangular sheet shape, for example, and is formed from aluminum or an alloy thereof. At least a part of the surface of the sheet member 10 is covered with an anodized film 12, and an antibacterial metal 14 made of silver and / or copper is deposited on at least a part of the anodized film 12. (See FIG. 4).

  The manufacturing method of the sheet member 10 will be briefly described. First, the sheet member 10 formed of aluminum or an alloy thereof is immersed in an electrolytic solution filled in an electrolytic cell (not shown). As the electrolytic solution, for example, a sulfuric acid bath, an oxalic acid bath, or a mixed bath thereof is used, and silver nitrate, copper nitrate, or both of them as a metal nitrate is added to such a bath. Or you may make it replace with such nitrate and add silver sulfate as a metal sulfate, copper sulfate, or both. AC / DC superimposed current (that is, current obtained by superimposing alternating current and direct current on DC side), PR current that flows negative wave, or pulse wave that flows negative wave from a pair of electrodes (not shown) provided in the electrolytic cell When an electric current is supplied to the surface of the sheet member 10 via the electrolytic solution, the sheet member 10 is subjected to a surface treatment, and an anodic oxide coating 12 (so-called anodized coating) is formed on part or all of the surface of the sheet member 10. It is formed. The anodic oxide coating 12 is composed of a barrier layer 16 formed on the surface of the sheet member 10 and a porous layer 20 formed on the surface of the barrier layer 16 and having a large number of holes 18. By performing the surface treatment on the sheet member 10 as described above, the nitrate (or sulfate) metal 14 (that is, the antibacterial metal 14) is deposited in each of the many holes 18 of the porous layer 20 ( (See FIG. 4). For example, when using silver nitrate (or silver sulfate) as the metal nitrate, silver, copper when using copper nitrate (or copper sulfate), silver nitrate and copper nitrate (or silver sulfate and copper sulfate) When both of the above are used, both silver and copper are deposited on the bottom of the numerous holes 18 of the porous layer 20. Therefore, by performing the above-described surface treatment on the sheet member 10, the antibacterial metal 14 composed of silver and / or copper is deposited on at least a part of the anodic oxide coating 12 covering the surface of the sheet member 10. Since the antibacterial metal 14 deposited on the sheet member has an antibacterial action, the sheet member 10 is given antibacterial properties.

  Next, the structure of the insole 2 of the shoe according to the present embodiment will be described. The other surface of the front member 6 (the lower surface in FIG. 3) and one surface of the main body member 4 (the upper surface in FIG. 3) are, for example, They are connected to each other by an adhesive or the like, whereby one side of the main body member 4 is covered with the front member 6 to form the insole main body 8. Alternatively, the front member 6 and the main body member 4 may be coupled to each other by stitching the outer peripheral portions of the superposed front member 6 and the main body member 4 with a thread (not shown). A sheet member 10 is attached to a central portion of one side of the main body member 4 (or the other surface of the front member 6) by, for example, an adhesive, so that the sheet member is interposed between the front member 6 and the main body member 4. 10 is interposed. An edge member 22 made of, for example, an elongated cloth member is attached to the outer peripheral portion of the insole main body 8 configured in this way, for example, with an adhesive or the like. The front member 6 and the main body member 4 are prevented from varying from each other, and the outer peripheral portion of the insole main body 8 can be reinforced. In particular, since the outer peripheral portion of the front member 6 made of tatami surface material is weak in strength, it is possible to enhance the durability of the insole main body 8 by covering the outer peripheral portion of the insole main body 8 with the edging member 22. Become. The insole of the shoe is composed of a pair of an insole 2 for the left foot, an insole 2 for the left foot and an insole for right foot (not shown) symmetrical to the left and right. Of these, the insole 2 for the left foot is shown.

  The insole 2 configured as described above is detachably placed on the inner bottom of a shoe (not shown) with the front member 6 facing upward, thereby achieving the following effects. Is done. Since the antibacterial metal 14 composed of silver and / or copper is deposited on the anodized film 12 covering the sheet member 10 as described above, the antibacterial action of the antibacterial metal 14 causes the inside of the shoe. It becomes possible to suppress the propagation of various bacteria. Moreover, when the propagation of various germs is suppressed in this way, the generation of odor due to the various germs can be suppressed, and the antibacterial property can be enhanced and the inside of the shoe can be kept clean. Further, when the humidity inside the shoe increases due to sweat or the like, the antibacterial metal 14 deposited on the anodized film 12 is ionized, and the ionized antibacterial metal 14 is released to the surroundings. For example, when silver nitrate (or silver sulfate) is used as the metal nitrate, silver ion 24, when copper nitrate (or copper sulfate) is used, copper ion 26, silver nitrate and copper nitrate (or sulfuric acid) When both silver and copper sulfate) are used, both silver ions 24 and copper ions 26 are generated, and these silver ions 24 and / or copper ions 26 pass through a large number of gaps formed in the surface member 6. (See FIGS. 3 and 4). Since the silver ions 24 and the copper ions 26 have a stronger antibacterial action, the silver ions 24 and / or the copper ions 26 are released into the inner space of the shoe, thereby causing secretions such as sweat and fat. This makes it possible to more reliably suppress the propagation of germs even within the shoe where germs tend to propagate, and to obtain higher antibacterial properties. In addition, since the surface member 6 is comprised from the tatami surface material, the touch at the time of mounting | wearing shoes becomes good, and it can prevent foot stuffiness etc. by the moisture absorption action and moisture release action which a tatami surface material has, It is possible to improve the comfort when worn.

  In the present embodiment, the outer shape of the sheet member 10 is configured in a rectangular shape, but is not limited thereto, and the outer shape can be set as appropriate. For example, when the outer shape of the sheet member 10 is configured to be substantially the same as the outer shape of the main body member 4, the sheet member 10 is interposed between substantially the entire area between the front member 6 and the main body member 4. Silver ions 24 and / or copper ions 26 are released over substantially the entire interior space of the shoe, and higher antibacterial properties can be obtained.

  Moreover, in this embodiment, although the sheet | seat member 10 was provided in the center part of the insole main body 8, it is not restricted to this, The arrangement | positioning site | part can be set suitably. For example, a plurality of (for example, three) sheet members 10 configured in a rectangular shape may be used, and the plurality of sheet members 10 may be provided on, for example, the toe portion, the arch portion, and the heel portion of the insole body 8. . Further, in the present embodiment, the sheet member 10 is interposed between the front member 6 and the main body member 4, but may be attached to the other surface of the main body member 4. In this case, silver ions 24 and / or copper ions 26 are released from a material having high air permeability such as a cloth member or a porous resin member so that the main body member 4 is released into the inner space of the shoe through the main body member 4 and the front member 6. It is preferable to configure.

  Next, another embodiment of a shoe insole will be described with reference to FIGS. FIG. 5 is a schematic cross-sectional view of a shoe insole according to another embodiment, and FIG. 6 is a simplified view of a state in which an antibacterial metal is deposited on a carbon material or an aluminum material mixed in the main body member of FIG. FIG. 5 and 6, the same components as those of the embodiment shown in FIGS. 1 to 4 are denoted by the same reference numerals, and the description thereof is omitted.

  In the insole 2A of the shoe of this other embodiment, the main body member 4A is composed of a cloth member such as a non-woven fabric or a woven cloth, and the main body member 4A is mixed with a powdery carbon material 28. An antibacterial metal 14A is deposited on the surface of the material 28 as described later. When mixing the carbon material 28 in the main body member 4A, for example, the powdery carbon material 28 is mixed in an adhesive (not shown) such as an inorganic adhesive, and the adhesive mixed with the carbon material 28 is used. It is applied to the surface of the main body member 4A. As a result, the adhesive enters the gap between the fibers 30 of the main body member 4A and adheres around the fibers 30, and the carbon material 28 is mixed in the main body member 4A (see FIG. 6). Alternatively, an adhesive is applied in advance to the surface of the main body member 4A, and the carbon material 28 is formed by pressing the powdery carbon material 28 into the adhesive applied to the surface of the main body member 4A with, for example, a spatula. The main body member 4A may be mixed. Since the carbon material 28 has conductivity, the carbon material 28 is mixed with the main body member 4A to impart conductivity to the main body member 4A, and the main body member 4A is subjected to the following surface treatment. Thereby, the antibacterial metal 14 </ b> A is deposited on the surface of the carbon material 28.

  The surface treatment method for the main body member 4A will be briefly described. First, the main body member 4A is immersed in an electrolytic solution filled in an electrolytic cell (not shown). As the electrolytic solution, for example, a sulfuric acid bath, an oxalic acid bath or a mixed bath thereof is used, and silver nitrate as a metal nitrate, silver sulfate as a metal sulfate, or both are added to such a bath. By supplying an AC / DC superposed current, a PR current flowing a minus wave, or a pulsed wave current passing a minus wave from a pair of electrodes (not shown) provided in the electrolytic cell to the surface of the main body member 4A via the electrolytic solution. The body member 4A is subjected to a surface treatment. When the surface treatment is performed on the main body member 4A in this manner, an anodized film 32 is formed on the surface of the carbon material 28 mixed in the main body member 4A, and a porous layer (not shown) forming the anodized film 32 is shown. The metal 14A of nitrate (or sulfate) (that is, the antibacterial metal 14A) is deposited in each of a large number of holes (see FIG. 6). Therefore, by subjecting the main body member 4A to the surface treatment described above, the antibacterial metal 14A composed of silver is deposited on the anodic oxide film 32 covering the surface of the carbon material 28, and the antibacterial metal 14A thus deposited is deposited. Since it has antibacterial action, antibacterial properties are imparted to the main body member 4A.

  The structure of the insole 2A of the shoe according to the present embodiment will be described. The other surface (the lower surface in FIG. 5) composed of the tatami surface material and the one surface (the upper surface in FIG. 5) of the main body member 4A. Are bonded to each other by, for example, an adhesive, whereby one side of the main body member 4A is covered with the front member 6 to form an insole main body 8A. An edge member 22 made of, for example, an elongated cloth is attached to the outer peripheral portion of the insole body 8A with, for example, an adhesive, as in the above-described embodiment.

  The insole 2A configured as described above is detachably placed on the inner bottom of a shoe (not shown) so that the front member 6 is on the upper side, thereby achieving the following effects. Is done. Since the antibacterial metal 14A composed of silver is deposited on the anodized film 32 covering the surface of the carbon material 28 mixed in the main body member 4A, the antibacterial metal 14A made of silver is deposited. It is possible to suppress the propagation of germs inside the shoe by the antibacterial action. In addition, when the propagation of germs is suppressed in this way, the generation of odor due to the germs can be suppressed, and the antibacterial property can be enhanced and the inside of the shoe can be kept clean. Further, when the humidity inside the shoe increases due to sweat or the like, the antibacterial metal 14A deposited on the surface of the carbon material 28 is ionized, and the ionized antibacterial metal 14A (that is, silver ions 24A) 6 is discharged into the inner space of the shoe through a large number of gaps formed in 6. Since the silver ions 24A have a stronger antibacterial action, the silver ions 24A are released into the shoe's internal space, so that even inside the shoe where bacteria can easily propagate due to secretions such as sweat and fat. Proliferation of miscellaneous bacteria is more reliably suppressed, and higher antibacterial properties can be obtained. Further, since the carbon material 28 has a deodorizing action for adsorbing odor, in addition to the antibacterial action of the antibacterial metal 14A, the carbon material 28 is generated inside the shoe by the deodorizing action of the carbon material 28 mixed in the main body member 4A. It becomes possible to remove the odor more effectively.

  In the present embodiment, the powdery carbon material 28 is mixed in the main body member 4A. However, instead of the carbon material 28, a powdered aluminum material 34 may be mixed in the main body member 4A. Also in this case, conductivity is imparted to the body member 4A, and the antibacterial metal 14A is formed on the surface of the aluminum material 34 by applying the surface treatment as described above to the body member 4A imparted with conductivity. It is deposited and the same effect as described above is achieved. Alternatively, both the carbon material 28 and the aluminum material 34 may be mixed in the main body member 4A.

  In the present embodiment, the main body member 4A is configured from a cloth member, but may be configured from a porous resin member such as polyurethane resin, polypropylene resin, polyethylene resin, or polystyrene resin. Since a large number of holes (not shown) are formed on the surface of such a porous resin member, as described above, an adhesive mixed with the carbon material 28 or the aluminum material 34 is used as the main member 4A. By applying to the surface, the carbon material 28 or the aluminum material 34 enters each of the many holes, and the carbon material 28 or the aluminum material 34 is mixed in the main body member 4A. Alternatively, the carbon material 28 or the aluminum material 34 may be mixed in the resin member before molding in advance, and the resin member may be molded in such a state that the carbon material 28 or the aluminum material 34 is mixed.

  In the present embodiment, the carbon material 28 or the aluminum material 34 is mixed in the main body member 4A. In addition to the carbon material 28 or the aluminum material 34, a powdery silica gel material (not shown) is used as the main body member. 4A may be mixed. Since the silica gel material has a water absorbing action and a deodorizing action, by mixing the silica gel material in the main body member 4A, moisture such as sweat can be removed inside the shoe, thereby preventing foot stuffiness and the like. In addition, it is possible to more effectively suppress the propagation of germs and the generation of odors.
