Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a connecting chair used in a theater, a hall or the like, and more particularly to a connecting chair provided with a novel air conditioning structure.
[0002]
[Prior art]
Instead of uniformly air-conditioning large theaters, halls, etc., various proposals have been made to increase the effect of air conditioning by blowing air-conditioned air to each seat, particularly in the vicinity of the back of the seat (for example, Patent Documents 1 to 3).

[Problems to be solved by the invention]
In what is disclosed in Patent Documents 1 and 2, conditioned air is blown upward from the upper end of the backrest of each seat, and in Patent Document 3, conditioned air is blown and reflected from behind on the backrest. However, in both cases, not only the air-conditioned air may directly hit the seated person, but also the air-conditioning efficiency is poor, and it is difficult to generate a laminar flow that easily sucks the ambient air, and it is necessary to provide it for each seat.
[0005]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and an object thereof is to provide a connecting chair that can efficiently air-condition a seated person with a simple structure without direct contact with the air-conditioned air. .
[0006]
[Means for Solving the Problems]
According to the present invention, the above problem is solved as follows.
(1) In a connecting chair configured by horizontally arranging seats having a seat and a backrest, the rear surface shape of the backrest is curved so as to be convex backward in a side view so as to enhance the Coanda effect. In addition, a guide plate extending from the rear lower end of the backrest to the floor surface is provided , and a blowout port for blowing conditioned air toward the guide plate is provided on the rear side of the guide plate on the floor surface. A cover plate standing from the floor on the rear side of the back plate is provided, the upper end of the cover plate is slightly above the lower end of the back surface of the backrest, and a gap is formed between the cover plate and the lower end of the back surface of the backrest. Like that .
[0007]
(2) In the above item (1), the outlet is disposed in front of the lower end of the backrest.
[0008]
(3) In the above item ( 1 ) or ( 2 ) , the air outlet is provided on the floor surface below one seat constituting the connecting chair, and the cover plate is provided on another adjacent seat constituting the connecting chair. with the Mowataru ones, but to close the outer end of the gap at the seat end, the gap between adjacent seat it shall not closed.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
1 to 3 show an embodiment of a connecting chair of the present invention, FIG. 1 is a perspective view thereof, FIG. 2 is an exploded perspective view thereof, and FIG. 3 is a conceptual longitudinal side view thereof shown with a seated person. is there.
[0010]
This connecting chair is composed of three seats (1a), (1b) and (1c) arranged side by side in the horizontal direction, each of which has a seat (2), a backrest (3) and an armrest (4) as the main components. It is configured as a member.
[0011]
The armrest (4) is formed by attaching decorative plates (7) on both sides of an armrest frame (6) formed on a vertical plate-like leg (5) that is erected on the floor and faces in the front-rear direction. The seat (2) is pivotally mounted between adjacent left and right legs (5) with pivots (8) projecting from both sides of the rear part.
[0012]
The rear surface of each backrest (3) is covered with a rear surface plate (9), and this rear surface plate (9) is gently curved so as to protrude rearward in a side view.
[0013]
As shown in FIGS. 1 and 3, a horizontal rectangular air outlet (10) for blowing conditioned air is formed in the floor surface below the central seat (1 b). As is apparent from FIG. 3, the air outlet (10) is disposed in front of the lower end of the rear plate (9) and is not exposed behind the seat.
[0014]
A guide plate (11) having a gentle curve is provided on the floor so as to continue from the vicinity of the front end of the air outlet (10) immediately below the seat (1b) to the lower end of the rear plate (9). The guide plate (11) is formed so as to connect the left and right plate-like legs (5) of the seat (1b) without any gap. A similar guide plate (11) is also installed in the seats (1a) (1c).
[0015]
The cover plate (12) over the entire width of the seats (1a), (1b), and (1c) extends upward from the vicinity of the rear end of the aforementioned air outlet (10), and the upper end and rear plate (9) of the guide plate (11). A narrow gap (d) (FIG. 1) is formed in the left-right direction between the lower end of the rear plate 9 and reaches a height position slightly above the lower end of the rear plate (9). As shown in FIG. 2, the cover plate (12) and the guide plate (11) form an air-conditioning air flow that is gradually throttled from the outlet (10) and blown out parallel to the rear plate (9). The
[0016]
The cover plate (12) terminates at the outer end of the seat (1a) (1c) at the end of the connecting chair, and here, a side closing member (blocking between the rear end of the legs (5)) ( 13) is attached, and the upper end of the side closing member (13) reaches a height position slightly above the lower end of the rear plate (9). Since there is no such side closing member between the intermediate leg (5) and the cover plate (12), a gap remains, and the conditioned air from the outlet (10) is passed through the gap between the left and right sides. It can also be led under the seat (1a) (1c). If necessary, a baffle plate (not shown) for guiding the conditioned air from the air outlet (10) to the left and right seats may be provided on the front surface of the cover plate (12).
[0017]
Since the connecting chair of the present invention has such a configuration, as shown in FIGS. 1 and 3, the conditioned air blown out from the floor outlet (10) is not limited to the central seat (1b). The back and back of the backrest, which is also led to the left and right seats (1a) and (1c) and curved convexly toward the rear from the gap between each guide plate (11) and cover plate (12) It blows upward along the face plate (9), and by the Coanda effect by the curved surface of the rear face plate (9), it becomes a laminar conditioned air flow, attracts ambient air, and rises while mixing with it. Thereby, it becomes possible to air-condition the surroundings of the audience seated on the seat locally and efficiently. At this time, a strong wind does not directly hit the rear seated person.
[0018]
In addition, by changing the curvature of the curvature of the back of the backrest in accordance with the position of the chair in a theater etc., and controlling the direction of the air flow from the top of the backrest, more appropriate air conditioning is possible. .
[0019]
【The invention's effect】
According to the first aspect of the present invention, the conditioned air that has been blown out is turbulent and wind tends to hit the seated person in the past. However, the conditioned air circulates along the rear plate, and the Coanda effect. By forming the laminar flow, the surrounding air rises while attracting and mixing, so that the wind does not directly hit the seated person, and the area around the seated person can be air-conditioned locally and extremely efficiently. Moreover, since it is only necessary to provide an air-conditioning air outlet on the floor surface in terms of structure, it is easy to install the connecting chair.
Furthermore, the shape of the back surface of the backrest is curved so as to be convex backward in a side view, and a nozzle shape for blowing air-conditioned air between the cover plate provided on the floor and the lower end of the back surface of the backrest By forming this gap, the Coanda effect can be enhanced.
[0020]
According to the second aspect of the present invention, the air outlet is concealed under the seat, so that it does not get in the way of the rear seat occupant and looks good.
[0021]
According to the invention described in claim 3 , the conditioned air can be distributed not only to the seat where the air outlet exists, but also to the seat next to the seat.
