Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ski device having a heat retaining function and a heating device for the ski device.

[0002]

2. Description of the Related Art Conventionally, ski equipment has a structure in which hard plastic is used on the outside and inner boots having a good heat retaining property are put inside and the waterproof property and the heat retaining property are combined. There is. As for ski gloves, ordinary gloves are made a little thicker and waterproof on the outside. In ski wear, the material with good heat retention such as down is also waterproofed on the outside. However, temperatures on the ski slopes can sometimes get quite low, and often the inner boots, a little thick gloves, and down are not enough to keep them warm, and skiers have to put up with a cold body.

In order to solve this problem, in ski shoes (Japanese Patent Laid-Open No. 60-232101), (Shokai 60-152).
301), (Actual Kaihei 3-4701) and other inventions and inventions have been made. Similar inventions and inventions have been made in ski gloves and ski wear.

[0004]

However, the above-mentioned invention (Japanese Patent Laid-Open No. 60-232101) has a drawback that the temperature sometimes rises too much because the temperature of the shoe sole is not controlled.

In addition, in (Actual Development Sho 60-152301),
When a shoe is loaded with a battery inside the shoe and the shoe is put on by a weight sensor, the shoe is automatically switched on and heated by an electric heater, but the battery has a small capacity and cannot be kept warm for a long time.

In (Actual Kaihei 3-4701), a heat insulating member, a heating wire for heating the heat insulating member, and a power supply port for supplying electricity to the heating wire are provided inside the ski boot. There is. The power supply port is a connection point for electricity, and if rust occurs in the power supply port due to snow, there is a risk of contact failure and abnormal heat generation. Furthermore, if power is supplied with snow adhered to the power supply port, there is a risk of short circuit or electric shock due to the melted snow.

The same problems also occur in inventions and devices relating to ski gloves and ski wear.

[0008]

In order to solve the above problem, in the present invention, a heat retaining member and a heating member for heating the heat retaining member are provided inside a ski equipment, and the heating member is a heating device. It was solved by heating from the outside of the ski equipment by electromagnetic induction.

[0009]

When the heating member inside the ski equipment is heated by electromagnetic induction by the heating device, the heat retaining member in contact with the heating member is warmed by the heat of the heating member to accumulate heat. Even if the heating of the heating member by the heating device is stopped, the body of the skier is kept warm by the heat accumulated in the heat retaining member.

Reference numeral 14 is a power supply device for converting the electricity supplied from the power supply plug 9 into a voltage and frequency suitable for the control device 10 and the high frequency power supply device 7.

Next, the operation of the heating device 13 will be described with reference to the control block diagram of FIG. First, the user puts the ski shoe 1 to be heated on the boot stand 5 and operates the start / stop switch 12 to start heating. When the start signal from the start / stop switch 12 is transmitted to the control device 10, the control device 10 reads the temperature of the temperature detecting portion 4 of the ski boot 1 by the temperature sensor 8 and confirms that the temperature of the heating member 2 is in a heatable state. To judge. When the measured temperature is higher than the reference value, the display device 11 displays a message to that effect and the heating is stopped.

Next, when the temperature read by the temperature sensor 8 is within the reference value, the high frequency power supply 7 supplied with electricity from the power supply 14 is operated. The high frequency power generated by the high frequency power supply 7 is applied to the heating coil 6,
The heating coil 6 generates a magnetic field.

Due to the magnetic field generated by the heating coil 6, the heating member 2 built in the ski boot 1 generates heat by an electromagnetic induction effect. The temperature rise of the heating member 2 is measured by the temperature sensor 8 in the temperature detecting unit 4, and the measured value is sent to the control device 10 every moment.

The control device 10 determines whether or not the received value is within a predetermined temperature rise range. When the measured temperature is higher than the reference value, the display device 11 displays a message to that effect and the heating is stopped.

If the measured temperature is within the reference value, the heating is continued, and the heating member 2 is heated to the predetermined temperature. When it is heated to a predetermined temperature, the high frequency power supply device 7 is stopped to end the heating of the heating member 2, the display device 11 is so notified, and the series of operations is ended.

Although the embodiment of the present invention has been described above by taking ski shoes as an example of ski equipment, the same applies to ski gloves and ski wear as the heating member 2 such as ski gloves and the inside of ski wear. A material, such as iron or stainless steel, in which eddy currents are generated by penetration of magnetic lines of force is formed into a fiber and woven into a cloth, and the heating member 2 is surrounded by a liquid, a solid or a gel like a ski boot. A heat insulating member 3 made of a material having a large specific heat is arranged so as to be in close contact with the heating member 2 so as to absorb heat from the heating member 2.

As the heating device 13, the mannequin doll is shaped like a ski glove,
It is heated by putting on ski wear. As a result, ski gloves and ski wear are heated to every corner without losing their shape.

Further, if the heating device 13 is built into a lift chair or handrail for carrying a skier to the upper part of the slope,
The skier is warmed while sitting on the lift and going to the top of the slopes.

Further, even if the inside of the gondola is heated, the heat is not transferred to the inside because the ski gloves and ski wear have good heat insulating properties, and the body of the skier who has cooled to the heart of the body by the cold does not warm up. By equipping the gondola with the heating device 13 and using the ski equipment having the heat retaining function of the present invention, the skier is warmed from the heart of the body in the gondola.

[0032]

[Effects of the Invention] By using the ski equipment having the heat retaining function, the skier can warm the whole body and enjoy skiing comfortably without enduring the cold even on a cold slope. Also, since you do not use a body warmer, you do not have to worry about the temperature rising too much during use, you do not have to worry about running out of battery because you do not use batteries, and there is no worry of electric shock due to electromagnetic induction heating.
