Description

[Detailed Description of the Invention] The present invention relates to heat-retaining clothing equipped with a heating element.

Clothing of this type is already known. For example, Japanese Unexamined Patent Application Publication No. 144202/1983 discloses incorporating a surface heating element inside a thermal garment. However, in conventional devices, the electrical operation portion is exposed to the outside of the clothing and is not organically connected to the functions of the clothing, making it uncomfortable to wear and having poor operability.

Therefore, an object of the present invention is to organically combine elements of the clothing itself with electrical elements to provide functional thermal clothing.

Based on the above object, the present invention connects the fastener of clothing to an electrical circuit, so that the amount of heat generated can be adjusted by opening and closing the fastener.

Hereinafter, the structure and operation of the present invention will be specifically explained based on embodiments shown in the drawings.

First, FIG. 1 shows a thermal clothing 1 of the present invention. The clothing body 2 of the thermal clothing 1 is, for example, a stadium jumper, and is equipped with a plurality of snap-type fasteners 3 at the joining position of the front body, and batteries or the like at appropriate positions between the outer material and the lining material. It houses a power source 4 and a large number of planar heating elements 5. This planar heating element 5 is formed into a flexible plate shape by making an electrical resistance wire into a woven fabric and covering the front and back surfaces with an insulating material such as vinyl chloride.

The above-mentioned snap-type fastener 3 and heating element 5
is connected in series with the switch 6 to the power source 4, as shown in FIG. Further, other snap-type fasteners 3 and heating elements 5 are each connected in series, and are connected in parallel to the other snap-type fasteners 3 and heating elements 5 connected in series. These electrical connections are made inside the clothing body 2 using electric wires 7, and as shown in FIG. It can be fixed using That is, the electric wire 7 is a covered wire, is attached as a lower thread of the sewing machine, and is successively fixed to one surface of the core material 8 by the upper thread 9. Note that the power source 4 may be connected to the outside using a plug or the like.

Next, the functions of the heat-retaining clothing 1 will be explained.

The user wears thermal clothing 1 and turns on switch 6.
After turning on the snap-type fasteners 3, the snap-type fasteners 3 are connected to the power source 4 and the heating element 5.
A closed circuit is formed by the electric wire 7. Therefore, the heating element 5 generates Joule heat due to its internal current. When a user removes one of the snap fasteners 3, the corresponding heating element 5 is separated from the power source 4. For this reason,
By opening the snap-type fastener 3, the wearer opens the connecting part and controls the temperature by taking in outside air, and also selectively disconnects the corresponding heating element 5 to control the amount of heat generated. It will be possible. Of course, when all the snap fasteners 3 are removed, the heating elements 5 are all connected to the power source 4.
It will be separated from

Next, Figure 4 shows the sliding fastener 3.
An example using . The sliding fastener 3 functions as a kind of slide switch, and depending on the position of the slider 3a, the resistor 11,
12 and 13 are successively connected into the circuit. When the slider 3a is completely pulled up, all the resistors 11, 12, and 13 are connected in parallel in the circuit, so the value of their combined resistance becomes small, so the current in the circuit increases and As a result, the heating element 5 is set to a strong heat generation state. Note that since the voltage of the power source 4 and the current in the circuit are set sufficiently low, there is no risk of electric shock.

In the above embodiment, the heating element 5 is configured as a planar heating element, but the heating element 5 may of course be a linear heating element. In addition, the above embodiment is
Both of them are equipped with a switch 6, but since the function of the switch 6 is obtained by connecting and disconnecting the fastener 3, the switch 6 can be omitted.

According to the present invention, the attachment/detachment operation or opening/closing operation of the fastener directly adjusts the amount of multiplication, and at the same time selects the heating element or heat generation amount, so a special electrical No operation is required, making it easy to handle.
