[overall structure]
As shown in FIG. 1A, a fan-equipped shoe 100 according to the present invention includes a shoe body 10, a fan 20, a power supply means 30, a pressure sensor 40, and an air-conditioning sole 50. As shown in FIG.

(Shoe body)
The shoe body 10 includes an upper 11 covering the user's foot and a sole 12 supporting the user's foot.
And prepare. The upper 11 and the sole 12 form a housing space 10A for housing the user's foot. As a material for the upper 11, any suitable known material such as woven fabric, synthetic leather, artificial leather, or natural leather can be used. Also, as the material of the sole 12, known materials such as synthetic rubber, rubber, polyurethane, synthetic leather, artificial leather, or natural leather can be used.
The shoe body 10 also includes an air intake portion 13 , an air discharge portion 14 , and an opening/closing mechanism 15 .

{Air intake/air discharge}
The air intake portion 13 is an opening for sucking air into the accommodation space 10A. The air intake portion 13 is provided at a front end portion (toe portion) 16 of the upper 11, as shown in FIG. 1A, for example.
The air discharge portion 14 is an opening through which the air taken in from the air intake portion 13 is discharged to the outside of the shoe body 10 . For example, as shown in FIG. 1A, the air discharge portion 14 is provided on the front side portion of the heel portion 17 behind the sole 12 .

The air taken in from the air intake portion 13 circulates through an air flow passage 521, which is a space in the air-conditioning sole 50, and is discharged from the air discharge portion 14. During this time, sweat from the user's feet evaporates. and the accommodation space 10A is cooled by the heat of vaporization.
In addition, since the air intake portion 13 and the air discharge portion 14 are provided above the lower end portion of the sole 12, even when stepping on a puddle, water or the like enters the accommodation space 10A. It's getting harder.

In addition, if the air intake portion 13 and the air discharge portion 14 are formed at a location where an air flow can be formed from the front end portion to the rear end portion of the accommodation space 10A, the accommodation space 10A can be cooled appropriately. Although preferred, it is not limited to the location shown in FIG. 1A. For example, the heel portion 17 may be provided with the air intake portion 13 and the toe portion 16 of the shoe body 10 may be provided with the air discharge portion 14 .

{Opening and closing mechanism}
The opening/closing mechanism 15 is a mechanism for opening and closing the air intake portion 13 and/or the air discharge portion 14, which are openings. As the opening/closing mechanism 15, for example, a known mechanism such as a wire fastener as shown in FIG. 1B can be used.

When it is raining or when a strong wind is blowing, the opening/closing mechanism 15 closes the air intake portion 13 and/or the air discharge portion 14, respectively, so that foreign matter such as raindrops and sand can be removed from the storage space 10A. can be prevented from entering. Then, when time passes and the weather turns fine, the opening/closing mechanism 15 opens the air intake portion 13 and/or the air discharge portion 14, thereby creating an air flow in the accommodation space 10A.

(fan)
The fan 20 is an axial fan having a motor (not shown) and a propeller (not shown), and draws air from the outside of the shoe body 10 into the housing space 10A, thereby causing the air to flow into an air flow passage 521, which will be described later. It is a configuration that forcibly causes The fan 20 communicates at its air suction portion with an air outlet portion 54 of the air conditioning sole 50, which will be described later.

In addition, in FIG. 1A, the fan 20 is shown to be embedded in the heel portion 17, but the installation location of the fan 20 is not limited to this. The installation position of the fan 20 can be appropriately and arbitrarily changed depending on the formation positions of the air intake portion 13 and the air discharge portion 14 . In particular, in the present embodiment, the fan 20 is provided near the air discharge portion 14 to serve as an exhaust fan, but the fan 20 may be provided near the air intake portion 13 to serve as an intake fan. A centrifugal fan may also be used depending on the arrangement and structure.

(Power supply means)
The power source means 30 is a power source device containing a battery, for example, and is electrically connected to the fan 20 by a power cable. The power supply means 30 is embedded near the fan 20 as shown in FIG. 1A.

Although the fan 20 and the power supply means 30 are assumed to be embedded in the vicinity of the heel portion 17, the present invention is not limited to this. Moreover, even if they are embedded in the shoe body 10, the fan 20 and the power supply means 30 are detachable from the shoe body 10 and can be replaced.

(pressure sensor)
The pressure sensor 40 is a pressure switch that switches ON/OFF of the fan 20 .
Since the ON/OFF of the fan 20 is switched by the pressure sensor 40, it is possible to save the user from having to perform the ON/OFF operation each time the fan-equipped shoe 100 is put on or taken off. Moreover, it is possible to prevent the user from forgetting to turn off the fan 20 . Moreover, the need to provide a power switch for the fan 20 is eliminated.

The pressure sensor 40 is configured to turn on the fan 20 only when the user is walking, and turn off the fan 20 when the user stops walking or takes off the shoe body 10 . This is because even if the fan 20 rotates when the pressure is not applied, the cooling effect is low and the energy is wasted.

Further, the pressure sensor 40 is arranged at a location where the pressure of the sole can be sensed, for example, near the heel portion 17 or near the arch of the foot as shown in FIG. 1A. In particular, the heel portion 17 is a portion of the shoe body 10 that is likely to be subjected to pressure only when walking. , the ON/OFF of the fan 20 is automatically switched according to whether or not the user is walking.

In this way, by providing the pressure sensor 40 so that the fan 20 is turned on only during walking when the temperature of the housing space 10A tends to rise, the user's feet can be warmed even if the fan 20 is turned on for a short time. can be sufficiently cooled. As a result, the operation time of the power supply means 30 can be extended, and from the viewpoint of downsizing, the power supply means 30 with a small capacity can be used.

The pressure sensor 40 may turn on the fan 20 only when the user puts his or her foot into the housing space 10A, for example. Also, the installation location is not limited to the vicinity of the heel portion 17, and may be the vicinity of the arch of the foot.

(air conditioning sole)
The air-conditioning sole 50 is an insole that is laid in the accommodation space 10A, and has a shape slightly smaller than the sole 12 in planes parallel to the front-rear direction and the left-right direction. The air-conditioning sole 50 includes a seat portion 51, a guide portion 52, an air intake portion 53, and an air outflow portion 54, as shown in FIGS. 2A and 2B.

{Seat part}
The seat portion 51 is a member that forms the outer surface of the air conditioning sole 50 .
The sheet portion 51 has at least moisture permeability. This is because the stuffy air in the accommodation space 10A escapes from the seat portion 51 to an air flow passage 521, which will be described later, and flows out of the shoe body 10, thereby eliminating the stuffiness in the accommodation space 10A.

Moreover, it is preferable that the sheet portion 51 has a waterproof property. Even if liquid such as rain enters the housing space 10A through openings such as the air intake part 13 and the air discharge part 14, the waterproof sheet part 51 prevents the soles from getting wet. Because it will be possible.

The sheet portion 51 may cover at least the upper surface of the guide portion 52 , and may be simply attached onto the guide portion 52 . Also, the seat portion 51 may cover the entire surface including the lower surface of the air conditioning sole 50 .

{Guide part}
The guide part 52 is space securing means that secures a space between the user's foot and the sole 12 and has a three-dimensional structure. Specifically, as shown in FIG. 2B, the guide portion 52 is made up of, for example, a plurality of substantially rectangular members, and supports the user's foot together with the seat portion 51 when the user wears the shoe body 10. Also, an air flow passage 521 is formed through which the air taken in by the air intake portion 53 flows. That is, by providing the guide portion 52 in the air-conditioning sole 50, it is possible to prevent the user's feet from blocking the flow path of the air taken in by the fan 20, which is formed in the accommodation space 10A (inside the air-conditioning sole 50). can be prevented.

As the material constituting the guide portion 52, any known material can be used as long as it has enough strength to prevent it from being crushed by the user's own weight, and sponge is preferable. Since the sponge has a predetermined elasticity, the air-conditioning sole 50 can be easily laid in the accommodation space 10A. In addition, it comes to bring excellent comfort to the user as a sole.

Note that the shape and arrangement of the guide portion 52 as shown in FIG. 2B are merely examples, and are not limited thereto. For example, as shown in FIG. 3, the air flow passage 521 may be formed by a plurality of elongated guide portions 52 in the front-rear direction. Alternatively, the air flow passage 521 may be formed by one tunnel-shaped guide portion 52 that is wide in the left-right direction and the front-rear direction and has an opening in the front-rear direction.

Further, when a plurality of guide portions 52 are provided, the configuration is not limited to the same elastic modulus or height. For example, the peripheral guide portion 52 of the air-conditioning sole 50 may be made of a (hard) material with a large elastic modulus, and the central guide portion 52 may be made of a (soft) material with a small elastic modulus. Alternatively, the guide portion 52 at the periphery of the air-conditioning sole 50 may be provided so as to be relatively high in the vertical direction, and the guide portion 52 at the central portion may be provided so as to be relatively low in the vertical direction.

By doing so, the guide portion 52 in the peripheral portion of the air-conditioning sole 50 preferably supports the user's foot, while the guide portion 52 in the central portion of the air-conditioning sole 50 bends. Therefore, in the fan-equipped shoe 100, both the maintenance of the air circulation passage 521 and the good wearing comfort are achieved.

[Air intake/air outflow]
The air intake portion 53 is an opening provided in front of the air-conditioning sole 50, as shown in FIG. 2A. The air intake portion 53 communicates with the air intake portion 13 of the shoe body 10 , and takes the air taken in from the air intake portion 13 into the guide portion 52 below the seat portion 51 .
Also, the air outflow portion 54 is an opening provided behind the air conditioning sole 50, as shown in FIG. 2B. The air discharge portion 54 communicates with the air discharge portion 14 of the shoe body 10 via the fan 20 , and discharges the air flowing through the air flow passage 521 from the shoe body 10 .

The air intake portion 53 and the air outflow portion 54 are not limited to simple openings as shown in FIG. 2A, and may be provided with a mesh material. Further, the formation locations are not limited to the front and rear ends of the air-conditioning sole 50, and may be appropriately changed according to the formation locations of the air intake portion 13 and the air discharge portion 14, and the like.
