Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat installed indoors or outdoors.

[0002]

2. Description of the Related Art Most of the seats provided in indoor facilities such as gymnasiums, theaters, and culture halls have about 10 seats arranged side by side, and their seat legs are attached to the floor of the facility and the seats are backrested. The shaft is supported so that it can be folded toward the part. (For example, Japanese Utility Model Laid-Open No. 54-75215, Japanese Utility Model Laid-Open No. 51-49212, Japanese Patent Laid-Open No. 51-47863) Meanwhile, benches installed in parks, seats installed in baseball fields, outdoor stadiums, etc. , These are called outdoor facility seats) are those that fix the seat legs to the ground, or those that are fixed to outdoor facilities.

[0003]

When using a seat in an indoor facility, since the indoor facility is cooled and heated by an air conditioner, the indoor facility can be used without distinction between day and night and in summer and winter. However, since there are individual differences in the strength of air conditioning, the comfort temperature differs, for example, for children, the elderly, or women, so if standard indoor air conditioning is used, some users may not be able to handle the air conditioning. At the same time, there was a problem that forced air-conditioning caused illness.

Since the environment of the outdoor facility is connected to the outside world, when the bench or seat of the outdoor facility in a cold area is used at night or in the winter, there is a problem that the user must take measures against the cold. It was Therefore, the present invention has been made in view of such problems of the prior art, and an object thereof is to provide a seat provided with a heating element inside a seat portion and a backrest portion. is there.

[0005]

In order to achieve the above object, a seat according to the present invention is provided with an insulating film heater, an aluminum foil laminated on at least one surface thereof, and protection thereof inside a seat portion and a backrest portion. A flexible heating element composed of a body is provided for each. Since the heating element has flexibility, it does not hinder the use of the seat and backrest, and the heat of the heater is
The heat can be transmitted to the surface layer of the seat and backrest through the aluminum foil, which has good thermal conductivity, so the seat can be warmed up arbitrarily.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a seat according to the present invention will be described with reference to FIG. 1 to FIG. 3, in which a seat portion 21 and a backrest portion 22 which constitute the seat 20 have flexibility. Since the heating elements 1 and 11 are provided respectively,
Is a laminate of a bendable insulating coating heater 2 on at least one surface of an aluminum foil 3 having good heat conduction, and at least the heater 2 is covered with a flexible protective member 4. The laminated side of the aluminum foil 3 is a seat portion. 21 and the backrest 22 are provided toward the surface layer portions 1a and 2a.

In the heater 2, a nichrome wire 9 is embedded in a bendable insulating sheet 12 in a meandering state, an electric wire connecting portion 5 is provided at a corner of the sheet 12, and the nichrome wire 9 and a cable 6 are connected to the electric wire connecting portion 5. It is a thing. As shown in FIG. 3, the protective body 4 covers only the heater 2, or the heater 2 and the aluminum foil 3 laminated on one side thereof, or the heater 2
And the aluminum foil 3 laminated on both sides thereof.

As a mounting means for the heating element 1, a contact plate 27 is attached to one surface of the heating element 1 as shown in FIG. 5, and a lower part of the center of the seat 21 is attached to the heating element 1 according to the size of the heating element 1. The concave portion 25 is opened downward, the heating element 1 is inserted into the concave portion 25, the heating element 1 is directed to the surface layer portion 1a, and the contact plate 27 is fixed to the seat portion 21.
The heating element 1 can be easily repaired or replaced by attaching the backing 26 to the bottom of the seat 21. The heating element 11 provided on the backrest 22 is also attached in the same manner.

[0009]

[Example] In the heating element 1 provided in the seat 20 for one person, the aluminum foil 3 has a length of 300 mm, a width of 300 mm, and a thickness of 0.0.
Using a heat-resistant PVC insulation coating heater in which the aluminum foil of about 6 mm is used in single or double, and the nichrome wire 9 having a resistance value of 330 Ω (85 Ω / m) is embedded in the heater 2 in a meandering state.
The wire connection part 5 is completely waterproof, and the power source is AC100.
V is used. For the protector 4, for example, neoprene sponge rubber or rubber sheet having a length of 300 mm, a width of 300 mm and a thickness of 5 mm is used.

Since the seat according to the present invention has the above structure,
The heating elements 1 and 11 are configured in advance, and when the seat portion 21 and the backrest portion 22 of the seat 20 are configured, the heating elements 1 and 11 are provided inside thereof and the cables 6 and 16 are externally provided. Pull it out. When the seat 20 is provided in an indoor facility or an outdoor facility, a distribution line W is laid according to the arrangement of the seats 20 in advance, and the cable 6, which is pulled out from the seat portion 21 and the backrest portion 22, is provided.
16 is inserted along the inside or outside of the seat leg 23, the seat 20 is attached, and the cables 6 and 16 are connected to the distribution line W as shown in FIG.

As a means for connecting the cables 6 and 16 and the distribution line W, the cables 6 and 16 are directly connected to the distribution line W, or the cables 6 and 16 are connected in parallel and connected to the distribution line W. A switch 8 is connected to at least one of the cables 6 and 16 as shown in FIG. 7, the switch 8 is attached to, for example, an armrest 24 of the seat 20, and the power supply to the heating elements 1 and 11 is interrupted by switching the switch 8. Is also possible. It is also possible to attach the plug 7 to the ends of the cables 6 and 16 and insert the plug 7 into the socket (not shown) of the distribution line W.

[0012]

Since the seat of the present invention has the above-mentioned structure, it has the following effects. A heating element is provided in the seat and backrest, and the heat of the heater is transmitted to the surface layer of the seat and backrest through the aluminum foil with good heat conduction, so it is possible to stop at a bus stop or a stop in a cold region. It has a particularly beneficial effect as a seat for an outdoor facility such as a station, a baseball field, or an outdoor stadium, or as a seat for an indoor facility such as a gymnasium, a theater, or a cultural hall having a large space with a high ceiling that has a poor heating effect.

In the heating element having aluminum foil laminated on both sides of the heater, when the heating element is provided in the seat portion and the backrest portion, the heating element can be provided without distinguishing the front and back sides of the heating element. Since it has flexibility, it does not hinder the use of the seat portion and the backrest portion, and it is possible for each person to warm up arbitrarily according to their physical condition. Moreover, in the hot-air type or duct type heating, there is a temperature-transmitting sound and a slight breeze is generated, but when the seat of the present invention is used, the temperature-transmitting sound and a breeze are not generated.
