BACKGROUND OF THE INVENTION
The present invention relates to a theater chair used in a theater, a hall or the like, and more particularly to a theater chair provided with a novel air conditioning structure.
[0002]
[Prior art]
Various proposals have been made to increase the air-conditioning effect around the seats by blowing air-conditioned air to the seats, especially in the vicinity of the backrest, instead of uniformly air-conditioning large theaters and halls. (For example, see Patent Documents 1 to 4).

[Problems to be solved by the invention]
In what is disclosed in Patent Documents 1 to 3, conditioned air is blown upward from the upper end of the back of each seat, and in Patent Document 4, conditioned air is blown and reflected from the back on the back. However, none of the air-conditioning efficiency is sufficient.
Patent Document 3 discloses a configuration in which conditioned air passes through the side legs of the seat. In this case, the conditioned air introduced into the side legs is released to the outside. Since it is sent to the backrest of the seat and blown upward from the upper end of the backrest, the structure becomes complicated and expensive.

[0010]
DETAILED DESCRIPTION OF THE INVENTION
1 to 3 show an embodiment of a theater chair according to the present invention. FIG. 1 is a rear perspective view thereof, FIG. 2 is a rear perspective view showing a part thereof exploded, and FIG. It is a rear perspective view of a unit.
[0011]
This theater chair is a pair of side legs (2) facing each other on the floor (1), with four vertical hollow plate-like side legs (2) facing in the front-rear direction. The connecting chair is composed of three seats (A), (B), and (C) each having a seat (3) and a backrest (4) between (2).
[0012]
Each seat ( 3 ) is pivotally mounted between a pair of side legs (2) and (2) with pivots (5) projecting on both sides of the rear part, and a use position facing forward and a folding position facing upward And can be rotated.
[0013]
The backrest (4) is fixed to the rear part of the pair of side legs (2) and (2) integrally with the rear plate (6) covering the rear surface.
[0014]
Each side leg (2) has a thin hollow box shape that is rectangular when viewed from the side, and a partition plate (8) that is inclined rearward and upward is provided in the middle portion of the hollow portion (7). The upper hollow portion (7) is filled with a sound insulating material (9) such as glass wool.
[0015]
An elbow rest member (10) is provided on the upper end of each side leg (2), and decorative edge materials (11) and (12) are provided on the front and rear end surfaces, respectively, and the upper end of the decorative edge material (12) on the rear end surface. The air outlet unit (13) is detachably provided.
[0016]
The rear end portion of the air outlet unit (13) has a substantially semicircular arc shape in plan view, and a slit-like air outlet (14) facing in the vertical direction is provided at the center of the rear end surface and both sides thereof. . These blower outlets (14) pass through the hollow parts of the blower outlet unit (13) and the decorative edge material (12) and the openings (15) provided in the rear end surface of the side legs (2), and the side legs ( 2) It communicates with the hollow part (7) inside.
[0017]
A horizontal rectangular supply port (16) for blowing out conditioned air is provided on the floor (1) surface directly below the central seat (B). The supply port (16) is disposed between a pair of left and right side legs (2) and (2) forming the central seat (B), and above the upper surface, the upper surface is a circle in a side view. A duct (17) that bulges in an arc and faces in the left-right direction is disposed so as to cover the supply port (16).
[0018]
Both ends of the duct (17) are connected to the lower ends of the opposite side surfaces of the pair of left and right side legs (2) and (2) forming the central seat (B), and the opposite side surfaces of each side leg (2). It communicates with the hollow portion (7) of each side leg (2) through an opening (18) drilled in the lower end portion of each side leg (2).
[0019]
Openings (18) similar to those described above are also formed at the lower ends of the side surfaces facing the outermost two side legs (2) and the inner side legs (2). (18) communicate with each other by a duct (17) similar to the above.
[0020]
Therefore, the conditioned air supplied from the supply port (16) flows in the left and right directions from the central duct (17) and enters the hollow part (7) of the pair of left and right side legs (2) and (2). And then into the hollows (7) of the outermost side legs (2) and (2) through the ducts (17) and (17) on both sides, and the hollows of each side leg (2). From the part (7), through the opening (15) and the hollow part of the decorative edge material (12) and the outlet unit (13), from the outlet (14) of the outlet unit (13), rear and both sides The air conditioned air can be effectively supplied to the occupant of the rear seat.
[0021]
In addition, each duct (17) can radiate heat from the surface of each duct (17) during heating to warm each seat (A), (B), and (C) thereon from below, and above it. If a seated person in the back seat puts his / her foot, the same effect as the foot warmer can be obtained. For this purpose, each duct (17) is preferably formed of a material having good thermal conductivity.
[0022]
FIG. 4 shows a modification of the outlet unit.
This air outlet unit (19) is provided with a long hole-like air outlet (20) facing in the left-right direction at the upper part of the rear surface having the same outer shape as the air outlet unit (13) and having a semicircular arc shape in plan view. It is.
[0023]
If this blower outlet unit (19) is used, air-conditioned air can be blown uniformly over both sides from the rear.
[0024]
It is convenient to prepare these two types of outlet units (13) and (19) so that they can be used properly or can be replaced in a timely manner according to changes in the usage environment and usage conditions. It is.
Further, it is more preferable that a known louver or other wind direction adjusting means, air volume adjusting means, or the like is provided in the air outlet unit.
[0025]
Furthermore, an air outlet may be provided on the front surface or the narrow side surface in the upper part of the side leg so that conditioned air can be supplied to a person sitting on a seat supported by the side leg.
[0026]
【The invention's effect】
According to the first aspect of the present invention, the air outlet provided in the rear end face of the side leg is made to project the air-conditioning air introduced into the hollow part of the side leg from the supply port provided in the floor surface backward from the backrest. From the unit, the air can be blown out rearward and laterally, and the conditioned air can be effectively supplied to the occupant of the rear seat, and the area around the occupant can be efficiently air-conditioned with a simple structure.
[0027]
According to the second aspect of the present invention, air for air conditioning can be distributed and supplied from a single supply port to the hollow portions of the plurality of side legs with a simple structure. If the seated person of the rear seat puts a foot on it, the same effect as a foot warmer can be produced.
[0028]
According to the invention described in claim 3, in the connecting chair in which a plurality of seats are connected in the lateral direction, air for air conditioning is distributed from a single supply port provided on the floor surface to the hollow portions of a number of side legs. In the same way as the effect of the invention described in claim 2, the heat can be radiated from the surface of the duct during heating, and the seat above it can be warmed from below, and the rear seat can be provided above it. If a seated person puts his / her foot, the same effect as that of a foot warmer can be obtained.
[0029]
According to the fourth aspect of the invention, the direction of the conditioned air blown from the outlet can be set or changed to a desired direction by the louver or other wind direction adjusting means, and the air volume adjusting means can be used. If the air volume can be adjusted, it is easy to use.
