Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air-conditioned chair installed as indoor equipment or outdoor equipment such as a theater, a stadium and a conference hall.

[0002]

2. Description of the Related Art Conventionally, as this type of air-conditioned chair,
Those disclosed in Japanese Utility Model Publication No. 63-4462 are known. In this air-conditioned chair, the supporting leg and the connecting horizontal rod are hollow to form an air passage.

[0003]

By the way, in the conventional air-conditioned chair described in Japanese Utility Model Publication No. 63-4462, the chair itself can be used as a part of an air-conditioning facility. However, since the fulcrum of the chair and the horizontal rod for connection serve as the air passage, there are restrictions on the air-blowing locations for air conditioning, and there are cases where suitable air conditioning cannot be performed.

In view of the above problems of the prior art, the present invention eliminates the restriction of the air-conditioning air-blowing part by using the chair and the backboard itself as the airflow passage and forming the airflow opening in the backboard. , An object is to provide an air-conditioned chair that can be used for good air conditioning.

[0005]

The present invention has the following constitution to achieve the above object. That is, the air-conditioned chair according to the present invention is a chair having a supporting leg standing on the floor of a building and a back plate attached to the supporting leg,
The back plate has a hollow double wall structure made of synthetic resin, the hollow part of the back plate of the hollow double wall structure serves as a ventilation passage, and a part of the back plate wall is cut off to form a ventilation opening leading to the ventilation passage. It will be.

[0006]

According to the air-conditioned chair according to the present invention, the back plate itself having the hollow double-wall structure is used as the air passage and the air blowing opening is provided in the back plate. It is possible to provide a ventilation position for air conditioning in an appropriate place.

DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows an embodiment of the present invention.
In FIG. 1, 1 is a connecting chair installed in a theater or the like, 2 is a side plate also serving as a supporting leg, and 3 is a back plate. Side plate 2
The back plate 3 is made of synthetic resin and has a hollow double wall structure. The upper end of the side plate 2 is an armrest 4. 5
Is a seat.

As shown in FIG. 1 (c), the back plate 3 having the hollow double-wall structure has an air passage 6 formed in its hollow portion. The air passage 6 is exposed from the back wall side. The ribs 7 are formed on the wall to partition the hollow portion. 7a
Is a welded portion at the tip of the rib. Since the air passage 6 defined by the ribs 7 is formed in the vertical direction of the back plate 3, the back plate 3 is reinforced by the ribs 7 and high strength and rigidity can be obtained. The upper part of the back plate 3 is shown in FIG.
As shown in FIG. 3, a blower opening 8 is formed by cutting off a part of the back wall and communicating with the blower passage 6. A frame member 9 provided with a louver 9a for adjusting the blowing direction and opening and closing the blowing opening 8 is attached to the blowing opening 6. As shown in FIG. 2, the air passage 6 of each back plate 3 is projected to the lower side surface of the back plate 3 to connect the connecting tube portion 10 to the air passage 6 of the adjacent back plate 3 through the through hole 11 of the side plate 2. Are connected in series, one end of which serves as an air inlet and is connected to an air supply source (not shown). In this way, air is taken in from the lower part of the back plate 3 and the air passage 6 reaching the air blowing opening 8 is formed in the back plate 3.
Since it is formed inside, the equipment for air conditioning is not conspicuous and the appearance is not impaired when a large number of chairs are installed, such as in a theater. In addition, since the ventilation opening 8 is provided on the back wall of the back plate 3, in a collective chair in which chairs are arranged in front and rear rows, air conditioning is performed especially in front of the user, so that highly efficient air conditioning is performed. Be seen.

The side plate 2 and the back plate 3 are made of ABS resin,
It is made of blow-moldable hard thermoplastic resin such as styrene-modified polyphenylene oxide resin, polyamide resin, polycarbonate resin, and polypropylene resin.

3 and 4 show another embodiment of the present invention. In this embodiment, FIG.
As shown in FIG. 5, the ribs 7 are welded to each other on opposite side surfaces of the ribs 7 so that no concave groove appears on the back wall side, thereby improving the appearance of the back wall. As shown in (c) of FIG. 3, the horizontal frame 12 serving as the leg base of the chair is used as a blower tube 13, and the lower part of the blower passage 6 of the back plate 3 is fitted with the connection port 14 to the blower tube 13 of the horizontal frame 12. To communicate with each other. In this embodiment, as shown in FIG. 4, a heating / cooling device 15 utilizing the Peltier effect is provided near the air blowing opening 8 of the air blowing passage 6. 16 is its power supply / control device, 17 is a switch, and 18 is a perforated plate-like PCT having opposite electrode plates on both sides.
It is an element. The rest of the configuration is the same as that of the embodiment shown in FIGS.

In each of the embodiments constructed as described above, since the back plate 3 itself having a hollow double-wall structure is used as the air passage 6 and the back plate 3 is provided with the air blowing opening 8, the air is blown. By using the back plate 3 having a wide opening 8, the air blow for air conditioning can be provided at an appropriate place, and optimal air conditioning can be performed.

[0012]

According to the present invention, it is possible to obtain a chair with an air conditioner capable of performing a good air conditioner without the restriction of the air-blowing part for the air conditioner.
