Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to far-infrared thermal footwear capable of warming the foot.

[0002]

[Prior art]

 Conventionally, in order to prevent the foot from getting cold, it has been customary to pull an insole on the inside of the shoe for this purpose. Also, when sitting on a chair, a slipper-type heating device may be used to heat the legs. This heater had a nichrome wire heater built into the bottom of the slipper, and the power supplied to this nichrome wire was obtained from a commercial AC power supply via a cord.

[0003]

[Problems to be solved by the device]

 However, pulling the insole on the inside of the shoe does not warm the foot, so it is not very useful in cold weather. In addition, the slipper-type heating device has a built-in heater so that it can warm the feet, but since the cord is connected, it is not possible to walk around with the slippers on.

Therefore, an object of the present invention is to provide far-infrared thermal insulation footwear that can warm the foot and can walk around.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the footwear according to the present invention, a planar heating element having a self-temperature control characteristic is arranged at the position where the foot touches.

Further, in the footwear according to the present invention, a battery for supplying electric power to the planar heating element is built in the heel of the footwear.

[0007]

According to the footwear according to the present invention, the planar heating element is arranged at the portion where the foot hits. This planar heating element generates heat and emits far infrared rays, so that the foot can be warmed.

Further, according to the footwear according to the present invention, since a battery for supplying electric power to the planar heating element is built in the heel, a cord for supplying electric power to the planar heating element from the outside is required. Instead, you can walk around wearing these shoes.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an embodiment of the footwear according to the present invention as seen from the side, and FIG. 2 shows the footwear of this embodiment as seen from below. As is clear from these figures, the footwear in this embodiment is a shoe. The shoe has a double sole and has a first sole 1 and a second sole 2. A semi-circular planar heating element 3 is sandwiched between the first and second soles 1 and 2 on the tip side of the shoe.

This planar heating element 3 is referred to as a temperature sensitive element described in Japanese Patent Application Laid-Open No. 2-156502 and Japanese Patent Application Laid-Open No. 3-132001, or heat generation described in Japanese Patent Application Laid-Open No. 3-205777. It is called the body. The temperature-sensing elements described in the former two publications are a composite material in which a cross-linking polymer, a low-dimensional material mainly composed of a linear polymer, and an inorganic compound are combined with graphite or carbon black, and the latter. The heating element described in that publication is obtained by applying this composite material to a cloth.

This composite substance has a self-temperature control property, that is, as long as a constant voltage is applied, the composite substance maintains its own temperature substantially constant even if the temperature of the environment changes. When this composite material is applied to a cloth and cut out in a semicircular shape, the planar heating element 3 is formed. Therefore, as long as a constant voltage is applied to the flat heating element 3, the flat heating element 3 keeps its temperature substantially constant. Although this temperature depends on the applied voltage, it is in the range of 25 degrees Celsius to 75 degrees Celsius, and is suitable for keeping the foot warm. Also, because of this self-temperature control characteristic, it is not necessary to provide a thermostat, which is also an advantage. Further, since the planar heating element 3, that is, the composite material described above, also radiates far infrared rays, it has an advantage that it has a mild warm feeling and is good for health.

On the other hand, the heel 4 is integrally formed on the first bottom 1. A hole 4a is formed on the rear side of the heel 4, a battery 5 is inserted into the hole 4a, and the hole 4a is closed by a lid 6. A switch 7 is arranged on the upper side of the heel 4. This switch 7 penetrates through the second bottom 2 and protrudes, and when this protruding part is pushed down, this switch 7 is turned on. Further, although not shown here, a line for supplying electric power from the battery 5 to the planar heating element 3 is arranged, and a switch 7 is inserted in this line. Therefore, electric power is supplied from the battery 5 to the planar heating element 3 only when the switch 7 is turned on, and the planar heating element 3 maintains a constant temperature.

Now, when such a shoe is worn, the switch 7 is turned on by the foot, the planar heating element 3 generates heat at a constant temperature, and radiates far infrared rays, so that the foot is warmed. These shoes can be used not only in daily life, but are very effective, for example, in the case of working in a refrigerator room.

FIG. 3 shows another embodiment of the footwear according to the present invention. In this embodiment, a rectangular flat heating element 11 is built in a shoe insole 12, a cord 13 connected to the flat heating element 11 is pulled out from the insole 12, and a plug 14 is attached to the tip of the cord 13. Are connected. The insole 12 is placed on the inside of the shoe, the cord 13 is drawn around, the plug 14 is connected to a battery (not shown), and power is supplied to the planar heating element 11 through the cord 13. The battery used here may be the battery 5 built in the heel 4 of the shoe shown in FIG. 1 or another battery.

In the above embodiments, shoes and insoles have been illustrated, but the present invention is not limited to these, and the present invention is also applied to boots, slippers, clogs, socks, and socks. be able to.

[0017]

【effect】

 As described above, according to the footwear according to the present invention, since the flat heating element is arranged, the foot can be warmed by the heat generated by the flat heating element and the far infrared radiation. In addition, since the battery that supplies power to the planar heating element is built into the heel, it is possible to walk around while wearing this footwear.
