Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe having a sanitary holding portion for removing the malodorous components, bacteria and the like in the shoe to keep the inside of the shoe clean.

[0002]

2. Description of the Related Art Generally, when a person wears a shoe, the shoe is in a hermetically sealed state, and the inside of the shoe is apt to get stuffy due to sweating or the like. For this reason, the shoes may cause a bad odor, or may become a hotbed of bacteria and mold, resulting in an unsanitary condition. In view of such a point, it has been well known that an insole made of activated carbon is used to adsorb a malodorous component by the activated carbon to deodorize.
However, when the adsorption of the activated carbon is saturated, the deodorizing action is reduced, and the deodorizing action cannot be continuously maintained. Therefore, when continuous deodorization is desired, it is necessary to replace the insole. Besides, this insole made of activated carbon,
Although it was possible to deodorize, it was not possible to sterilize or antibacterial at the same time.

In order to simultaneously perform deodorization, sterilization and antibacterial treatment, it has been proposed to use a photocatalyst. Conventionally, this photocatalyst is deodorized exclusively in the room.
Attempts have been made to develop a method of using a sterilizer and a method of supporting a photocatalyst, such as a method of spraying or applying it as a paint. This deodorizing / sterilizing device irradiates the photocatalyst with ultraviolet rays to cause a photochemical reaction, and decomposes the malodorous components such as sulfur compounds and nitrogen compounds present in the air and bacteria to decompose the malodorous components. It is intended for sterilization and antibacterial. Thus, in order to perform deodorization, sterilization, and antibacterial using a photocatalyst, it is necessary to secure light irradiation and air circulation to the photocatalyst.

[0004]

However, the structure of the deodorizing / sterilizing device using a photocatalyst arranged in the room cannot be applied to shoes as it is. In particular, since the shoe has a special shape that conforms to the shape of a human foot, when the photocatalyst is used in the shoe, it is difficult to irradiate the photocatalyst with light and ensure air circulation. In addition, shoes are used particularly in a situation where they are easily affected by the external environment, but if stains or the like adhere to the photocatalyst, the photochemical reaction thereof may deteriorate.
Furthermore, when attaching the photocatalyst to shoes, the photocatalyst rubs or falls off due to contact with the human foot inside the shoe and external objects on the outside of the shoe, and the photocatalyst deodorizes. There is a risk that the bactericidal and antibacterial effects may not be fully exerted.

In order to solve the above-mentioned problems, the present invention provides a shoe capable of keeping the inside of the shoe clean by sufficiently exhibiting the sanitary retaining action of the photocatalyst such as deodorization, sterilization, and antibacterial action in the shoe. It is provided.

[0006]

As a first means for solving the above problems, the present invention is a shoe having a sanitary holding portion attached to the shoe body for deodorizing, sterilizing, antibacterial, etc. the shoe body. The sanitary holding part includes a photocatalyst element containing a photocatalyst and a support means for supporting the photocatalyst element in the shoe body so that light can be received and ventilated. Is.

As a second means for solving the above problems, the present invention is a shoe having a sanitary holding portion attached to the shoe body for deodorizing, sterilizing, antibacterial, etc. the shoe body. Is a photocatalyst element provided in the shoe body and containing a photocatalyst, a support means for supporting the photocatalyst element in the shoe body, a light transmitting means provided in the shoe body so that the photocatalyst element is irradiated with light, and a photocatalyst element The present invention provides a shoe characterized by comprising a ventilation means for contacting air.

Further, the present invention provides the shoe according to the first or second means, characterized in that the above-mentioned photocatalytic element is covered with a light-transmitting layer and a porous layer or a light-transmitting layer. It is a thing.

[0009]

According to this structure, even if a photocatalyst is used in shoes, the photocatalyst can be irradiated with light and the contact between the photocatalyst and air can be ensured. Since it is covered, it can prevent the photocatalyst from becoming dirty, falling off, and rubbing while ensuring the transparency and air permeability to the photocatalyst. It can be fully demonstrated within.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a shoe 10 according to the present invention. The shoe 10 has a sanitary holding portion 14 attached to the shoe body 12 for deodorizing, sterilizing, antibacterial, etc. the shoe body 12.

The shoe body 12 is, as shown in FIG.
Comprised of an upper 50 and a sole 52, the upper 50
Has a tongue 54 for restraining the instep and an opening 56 for inserting the foot. As described above, in the embodiment of FIG. 1, the shoe body 12 is shown to be an athletic shoe, but it may be a general shoe such as a business shoe other than the athletic shoe.

Further, the sanitary holder 14 includes a photocatalyst element 18 including a photocatalyst 16, and the photocatalyst element 18
And a supporting means 20 for supporting the shoe body 12 so that light can be received and ventilated.

As the photocatalyst 16, Cds, Wo ₃ , F
Although various photo-semiconductor ceramics such as e ₂ O ₃ can be used, they are available at a relatively low cost, have a strong photocatalytic action, and can effectively perform deodorization, sterilization, and antibacterial treatment. It is desirable to use TiO ₂ (titania oxide). Further, this TiO ₂ is suitable because harmful ions and the like do not dissolve out. Incidentally, since the activity is high, as the TiO _2, it is desirable to use a TiO ₂ having a crystal form of anatase type may be used of TiO ₂ having other crystal form of rutile type.

When the photocatalyst 16 is irradiated with light, the electrons in the valence band are excited by the conductor to generate holes in the valence band, and the holes extract the electrons and oxidize them. Because it has, it deodorizes by decomposing malodorous components such as sulfur compounds, and also causes respiratory inhibition due to the oxidation of bacteria and sterilizes it. Therefore, according to the photocatalyst 16, deodorization and sterilization / antibacterial can be performed at the same time, and deodorization, sterilization / antibacterial can be performed without using a special large-scale device. It can be applied to deodorization, sterilization and antibacterial, and can maintain hygiene such as deodorization and sterilization without damaging the shoe body 12.

The photocatalyst element 18 may be the photocatalyst 16 alone, but is preferably formed by depositing the photocatalyst 16 on a supporting substrate such as a polyester fibrous sheet 22 as shown in FIG. It This photocatalyst 16
The polyester fibrous sheet 22 is preferably adhered to the fibrous sheet 22 by spraying the photocatalyst 16 in the form of fine particles at a low temperature. Because the shoe body 1
Since 2 is accompanied by some deformation when used,
As its material, it is necessary to use a high temperature weak body such as a sheet or cloth made of polyester fiber that can follow the deformation of shoes, but according to this low temperature spraying,
This is because these high-temperature weak bodies can be used as the supporting substrate because the thermal effect exerted on these supporting substrates is small.
Further, when the photocatalyst 16 is in the form of fine particles, the contact area of the photocatalyst 16 with air and light is increased, and the deodorizing / sterilizing action can be efficiently exhibited. In addition, at the time of this low temperature spraying, if a fine powder having a diameter smaller than that of the photocatalyst 16 having fine particles is mixed, it is possible to prevent a so-called bridging phenomenon in which sharp-angled portions of the fine particles are bite-bonded to each other, and the adhesion thickness varies. Can be prevented. Further, the fibrous sheet 22 made of polyester, which is a supporting substrate.
It is desirable to impregnate the above with an adhesive because the adhesive strength with the photocatalyst 16 can be increased. The photocatalyst element 18 can be formed on the carrier substrate by a combination of metal spraying and titania spraying or other suitable means.

The photocatalyst element 18 formed in this manner is, as shown in FIGS. 1 and 3, the shoe body 1
It is machined to a size such that it can be mounted in a mounting hole 12a formed in a part of the upper surface of the second toe part. As the shape, as shown in FIG. 1, it is possible to process into any shape other than a square shape.

In the embodiment of FIG. 1, the support means 20 is shown in FIG.
, The photocatalyst element 18 is attached to the upper surface of the toe portion of the shoe body 12 so as to correspond to the attachment hole 12a of the shoe body 12. Therefore, as shown in FIGS. 1 and 3, the photocatalyst element 18 has one surface (outer surface) facing the surface of the shoe body 12 and the other surface (inner surface) facing the inside of the shoe body 12. Therefore, the photocatalyst element 18 is capable of receiving light and is supported by the shoe body 12 so as to be able to ventilate so as to come into contact with the air in the shoe body 12, and the photocatalyst 16 has sufficient deodorizing, sterilizing, and antibacterial actions in the shoe. Can be demonstrated. The reason why the photocatalyst element 18 is supported in the toe part of the shoe body 12 is that it is the most suitable position for receiving light and ensuring ventilation. Therefore, if it is possible to similarly receive light and ensure ventilation, the shoe body 1
The photocatalytic element 18 may be supported by another portion of the photocatalyst element 2, for example, the tongue 54 shown in FIG.

The photocatalyst element 18 is preferably coated with a translucent or porous coating layer on the surface contacting an external object or a human leg. In the illustrated embodiment, as shown in FIG. 4, the photocatalyst element 18 has an outer surface covered with a translucent coating layer 24 and an inner surface covered with a porous coating layer 26. Therefore, during use, the photocatalyst 16 does not come into contact with human feet or external objects and is not rubbed or dropped, and it is possible to prevent dirt such as mud from directly adhering to the photocatalyst element 18. The photocatalyst 16 does not impair the deodorization and sterilization / antibacterial action. Further, the dirt attached to the translucent coating layer 24 can be easily removed by washing with water or the like.
The hygiene holding action of 6 can be always exerted.

As described above, when the photocatalytic element 18 is covered with the translucent coating layer 24, the photocatalyst 16 can be secured to be irradiated with light, and the sanitary holding action such as deodorization and sterilization of the photocatalyst 16 is sufficiently exhibited. At the same time, it is possible to prevent the photocatalyst 16 from falling off and attaching dirt. The translucent coating layer 24 is preferably made of a resin transparent sheet or the like suitable for use in the shoe 10. Further, when the porous coating layer 26 is used, it is possible to secure the contact of the photocatalyst 16 with the air, thereby making it possible to decompose the malodorous component present in the air in the shoe body 12, and to sterilize or antibacterially. At the same time, it is possible to prevent the photocatalyst 16 from falling off or adhering to dirt. The porous coating layer 26 can be formed of a non-woven fabric, a sponge or the like which has been conventionally used as a material for shoes.

In this case, as shown in FIG. 4, since the light is emitted from the outside of the shoe body 12, a light-transmitting coating layer 24 is provided on the outside of the shoe body 12, and air and bacteria to be deodorized. Etc. are present in the shoe body 12,
The porous coating layer 26 is arranged on the inner side of the shoe body 12, and the photocatalytic element 18 is sandwiched between the porous coating layer 26 and the porous coating layer 26. When the photocatalyst element 18 is covered with the translucent coating layer 24 and the porous coating layer 26 as in this embodiment, as shown in FIG. 3, the translucent coating layer 24 and the porous coating layer are used. Layer 26, along with photocatalytic element 18, is also sewn to and supported by shoe body 12.

The position where the photocatalytic element 18 should be supported may be a side surface near the opening 56 of the upper 50, which has less foot contact, as shown in FIG. 1, in addition to the upper surface of the toe and the tongue 54 described above. In this case, since the light is sufficiently injected through the opening 56, the photocatalyst 16 can be sufficiently irradiated with the light, and the photocatalyst element 18 can be supported by the shoe body 12 so as to be able to receive light. Also, in this embodiment, the photocatalyst 16 is formed by forming the shoe body 12 from a porous material such as sponge or cloth material.
The contact with the air can be ensured, and the photocatalytic element 18 can be supported so as to be ventilated. Further, in this embodiment, when the photocatalyst element 18 is arranged so as to receive the light entering through the opening 56, the surface of the shoe body 12 facing the opening 56 is covered with the light-transmitting coating layer 24. It On the other hand, when the shoe body 12 is formed of a fabric material as described above, it is possible to ensure the flow of air through the fabric material to the photocatalyst 16, so that the porous coating layer 26 on the surface that contacts the fabric material is formed. It can be omitted. The photocatalyst element 18 may be supported not only at one position on the shoe body 12 but also at a plurality of positions, whereby the efficiency of actions such as deodorization and sterilization can be further improved.

In the above embodiment, the fibrous sheet 22 made of polyester was used as the supporting base of the photocatalyst element 18. However, other supporting materials such as cloth, foam, film and polyester can be used as long as the supporting base can support the photocatalyst 16. A sheet made of the above resin, or a metal can be used depending on the supporting position of the photocatalytic element 18. In addition to the low temperature spraying, the photocatalyst element 18 may be formed by applying the photocatalyst 16 as a paint and applying it to the supporting substrate, or as described above, by combining the metal spraying and the titania spraying. The photocatalytic element 18 may be formed. Further, as described above, the photocatalyst 16 itself may be used as the photocatalyst element 18 without interposing a supporting substrate.

In addition to the above-mentioned sewn portion, the supporting means 20 is sandwiched by a bonding means such as an adhesive, or as shown in FIG. 5, sandwiched between the materials constituting the shoe body 12. It may be a means. Further, the supporting means 20 may be a velcro tape, a hook-and-loop fastener having a large number of loop-shaped projections, or the like. These supporting means are preferable because the photocatalytic element 18 can be detachably supported on the shoe body 12. Other,
The translucent coating layer 24 and the porous coating layer 26, which are coated on the photocatalyst element 18 in a sandwich form, are projected from the peripheral surface of the photocatalyst element 18, and the projecting portions are sewn, adhered or supported by other appropriate means. You may.

In the above-mentioned embodiment, the light-transmitting coating layer 24 and the porous coating layer 26 are such that the light-transmitting coating layer 24 is arranged on one surface of the photocatalyst element 18 and the porous coating layer 26 is arranged on the other surface thereof.
The photocatalyst element 18 is arranged so as to be sandwiched by both, but if the photocatalyst 16 does not fall off, rub, or become dirty without coming into contact with an external object or human foot, one or the other surface The transparent or porous coating layer 24 or 26 can be omitted. In this case, for example, if the light-transmitting coating layer 24 has a large hole, sufficient light irradiation can be ensured. Therefore, the light-transmitting coating layer 24 is superposed on the porous coating layer 26 and the photocatalyst element is formed. 18 may be coated. If sufficient air circulation is ensured on the surface that comes into contact with an external object or human foot, only the translucent coating layer 24 may be coated. Of course, if it is not necessary to consider the photocatalyst 16 from dropping off, rubbing, adhering dirt, etc., the photocatalyst element 18 may be exposed without covering both of them. Depending on the position where the photocatalytic element 18 is supported, by exposing the photocatalytic element 18 in this manner, light irradiation and contact with air can be performed efficiently.

A second embodiment of the invention is shown in FIG. 6, in which the hygiene retainer 14 comprises a photocatalytic element 18 provided within the shoe body 12 and containing a photocatalyst 16.
In addition to the supporting means 20 for supporting the photocatalyst element 18 on the shoe body 12, the light transmitting means 3 provided on the shoe body 12 so that the photocatalyst element 18 is irradiated with light.
0 and ventilation means 32 for bringing air into contact with the photocatalytic element 18.

In the second embodiment, the photocatalytic element 18 carries the photocatalyst 16 on the upper surface of a resin finger plate 34 arranged at the tip of the shoe body 12 as shown in FIG. 6, for example. Are formed. In this case, the photocatalyst 16 is carried on the resin finger plate 34 by spraying at low temperature or by applying it as a paint. Further, when the photocatalyst 16 that can be easily processed is used, the finger plate 34 may be formed from the photocatalyst 16 itself. An adhesive, a surface fastener, or the like can be used as the support means 20, and the photocatalytic element 18 is fixed to the insole 36 in the shoe body 12 by fixing the finger plate 34 to the shoe body 12 with the adhesive, surface fastener, or the like. Can be supported by.

As shown in FIG. 6, the light transmitting means 30 comprises a light receiving window 38 provided in the shoe body 12, and the light receiving window 38 is provided above the finger plate 34 so that the finger plate 34 is irradiated with light. Is formed. The light receiving window 38 is formed of a transparent sheet or the like, and the transparent sheet or the like is attached to the shoe body 12 by an appropriate method such as sewing or adhesion. Since the light receiving window 38 is provided in this manner, when the shoe 10 is not worn, light can be injected from the light receiving window 38 into the shoe main body 12 to ensure the irradiation of light to the photocatalyst 16, and thus Therefore, the photocatalyst 16 can sufficiently exert the effects such as deodorization and sterilization.

The venting means 32 comprises, in the embodiment of FIG. 6, a porous insole 36 which is located below the finger plate 34 and which supports the finger plate 34, which is formed from a cloth or an open cell sponge. There is. Therefore, the photocatalyst 16
Can contact the air in the shoe body 12 through the insole 36, and can exert the effects of deodorization, sterilization, and the like.

The finger plate 34 may be formed of a porous material having air permeability or may be formed in a pure state. When the finger plate 34 is made of a porous material, the finger plate 34 itself has air permeability, so that the photocatalyst 16 can sufficiently contact the air to perform a photocatalytic action such as deodorization. Further, similarly to the previous embodiment, the upper surface of the finger plate 34 is coated with the transparent coating layer 24 such as a transparent sheet or the porous coating layer 26 to secure the irradiation of light to the photocatalyst 16 and the air circulation. At the same time, it is possible to prevent the photocatalyst 16 from dropping off, rubbing, and attaching dirt. Meanwhile, the finger plate 3
When 4 is formed in a pure state, it is preferable to expose the photocatalyst element 18 at least without covering the porous coating layer 26 in order to ensure sufficient air circulation to the photocatalyst 16. If the air permeability is high, the porous coating layer 26 may be coated.

Further, as shown in FIG. 7, the photocatalytic element 18 is attached to the heel portion of the insole 36 arranged in the shoe body 12 by a supporting means such as stitching, bonding, or a surface fastener so that the inside of the shoe body 12 can be prevented. May be supported by. In this embodiment, the opening 56 of the shoe body 12 is used as it is as the translucent means 30, and when the shoe is not worn, the light inserted into the shoe body 12 through the opening 56 is used to detect the photocatalyst 16. It exerts the effects of deodorization and sterilization. Thus, the translucent means 3
When the photocatalyst element 18 is supported on the heel portion of the insole 36 located just below the opening 56 as 0, sufficient photoirradiation to the photocatalyst 16 can be ensured. When the opening 56 is large and light is sufficiently inserted into the shoe body 12, the photocatalytic element 18 may be supported not only in the heel portion but also in a wider area.

Further, in the embodiment of FIG. 7, the ventilation means 32 is composed of a porous sheet 40 formed of a porous material such as sponge, which is arranged on the lower surface of the insole. The porous sheet 40 secures air circulation to the photocatalytic element 18 supported by the insole 36, and enables the photocatalyst 16 to sufficiently exert the effects of deodorization, sterilization and the like.

Further, in the embodiment shown in FIG. 7,
Since the photocatalyst element 18 is provided in the heel portion of the insole 36 and has a large contact surface with a human foot, the upper surface of the photocatalyst element 18 has a translucent coating layer 24 such as a transparent resin sheet or a porous coating such as a perforated sheet. It is desirable to coat the layer 26 to prevent the photocatalytic element 18 from falling off, rubbing, adhering dirt and the like. In this case, as the ventilation means 32, the porous sheet 40 arranged on the lower surface of the insole 36 is used.
It can be understood that since the photocatalyst 16 prevents the photocatalyst 16 from falling off, rubbing, etc., this porous sheet also serves as a porous coating layer. Therefore, it is not necessary to provide the porous coating layer 26 on the lower surface of the photocatalytic element 18.

The finger plate 34 shown in FIG. 6 and the insole shown in FIG. 7 may be used alone or in combination. This can be expected to further improve the efficiency of deodorization and sterilization.
