DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to an air conditioning structure for a staircase-like seat in a building having a staircase-like seat like a theater.

[0002]

2. Description of the Related Art In a large space building such as a stadium or a theater, a large number of people are accommodated, and indoor air tends to be polluted. Therefore, it is necessary to provide sufficient ventilation. Therefore, seat air conditioning may be performed. In this seat air-conditioning, an air-supplying passage for conditioned air is provided between a stepped floor and a floor slab, and conditioned air is blown to the lower part of each seat through an outlet opened in the floor.

However, the air-conditioned air blown out from the vicinity of the seat needs to be quickly discharged to the ceiling without staying in the vicinity of the air-conditioned area. ing.

[0004]

That is, as shown in FIG. 5, in this type of building, a pillar 4 of a seat 3 is fixed to each horizontal surface 2a of a step-like floor portion 2 arranged on a floor slab 1. There is a pillar 4 between the seat plate 3 a of the seat 3 and the floor 2.
The floor 2 so that a person sitting on the front seat 3 does not hinder a person sitting on the back seat 3 from watching.
The height of the vertical surface 2b and the height of the backrest 3b of the seat 3 are set.

Further, as shown by arrows, the conditioned air is supplied toward each seat 3 through an air supply passage A formed between the floor slab 1 and the floor 2.

Therefore, as shown in FIG.
For example, when opening the air-conditioning outlet 5 on the horizontal surface 2a,
It is necessary to open the lower part of the front surface of the seat plate 3a in order to avoid the interference of the seat plate 3a. However, since this portion also serves as a passage for the audience, it is easy for dirt to adhere thereto, and dust accumulated around the outlet 5 can be removed. There is a drawback that the air-conditioning air directly touches the feet of the spectators or the air outlet is closed, so that comfort cannot always be obtained.

Further, as shown in FIG.
When the air-conditioning outlet 5 is opened on the vertical surface 2b, the air flow only flows under the seat plate 3a if the air flow becomes parallel, so that the air flow rises along the back surface of the backrest 3b. It is necessary to adjust the flow direction of the air flow, and the position of the air outlet 5 is also limited. However, when the step of the vertical surface 2a is small, even if such a contrivance is taken, the air flow cannot be raised and the air flow cannot be increased at random. There is a risk of scattering.

The present invention has been made to solve the above problems, and has as its object the purpose of adding a simple structure to raise the flow of air-conditioned air that blows out horizontally by using the back of the backrest as a guide, and quickly. It is an object of the present invention to provide an air-conditioning structure for a staircase-like seat that can be discharged to a ceiling side.

Further, according to the present invention, during heating or the like,
It is another object of the present invention to provide a stair-shaped passenger seat air-conditioning structure that can be switched to allow warm air-conditioned air to flow under a foot.

[0010]

In order to achieve the above object, according to the present invention, a stepped floor provided on a floor slab, a large number of seats having pillars fixed on a horizontal surface of the floor, and An air conditioner comprising: an air supply passage for air-conditioning air formed between a floor and a floor slab; and an air outlet that opens in a vertical surface of the floor and blows out the air-conditioning air toward a lower rear surface of the seat. In the structure, the seat is folded under the back of the seat toward the bottom.
An airflow guide plate that can be folded and deployed is provided.

[0011]

Further, according to the present invention, the stepped floor is integral with the floor slab, and the inside of each vertical surface of the floor slab is surrounded by a partition wall to supply air-conditioned air in parallel with the vertical surface. And a configuration in which the outlet of the conditioned air is opened in the vertical plane.

[0013]

According to the above arrangement, the conditioned air blown horizontally from the vertical surface of the floor hits the airflow guide plate and rises along this surface and the back of the backrest connected thereto. Since this upward airflow is slightly ahead of the landing surface of the spectator's feet, it does not come into contact with dust or the like adhering to the floor, so that the airflow does not touch the feet or hinder the airflow.

The air-flow guide plate is folded toward the bottom of the seat only at the time of heating or the like, so that the conditioned air blows forward between the pillars and directly heats the feet.

When the configuration of claim 3 is adopted, the air-conditioning structure of the present invention can be applied to a floor unit integrated with a floor slab.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows an air-conditioning structure for a stepped seat according to a first embodiment of the present invention. Note that the same reference numerals are used for the same parts as in the related art, and only different parts are described using different reference numerals.

That is, in the present invention, the pillar 4 of the seat 3 is fixed to each horizontal surface 2a of the stepped floor portion 2 arranged on the floor slab 1 in substantially the same manner as in the prior art.
There is a gap between the seat plate 3a and the floor 2 of the height of the pillar 4, so that a person sitting on the front seat 3 does not hinder a person sitting on the back seat 3 from watching. Vertical surface 2b of the floor 2
And the height of the backrest 3b are set.

Further, the conditioned air of the present invention is supplied from the air supply passage A formed between the floor slab 1 and the floor portion 2 to an outlet opening at a position facing the back surface of each seat 3 on each vertical surface 2b. The air is supplied to the lower rear portion of each seat 3 through 10. The outlet guide plate 10a has an oblique angle of 45 ° at the outlet 10.
And the blowing angle is set to 45 °.

A skirt-shaped airflow guide plate 12 is arranged between the pillars 4 at the lower rear portion of the seat 3 so as to face the air outlet 10. As shown in an enlarged view of a part of the figure, the air flow guide plate 12 is rotatably mounted on both sides of the upper part thereof to the pillar 4 via a hinge shaft 14, and a spring provided around the hinge shaft 14. Due to the spring pressure of 16, the airflow guide plate 12 is always held at the deployed position so as to obliquely obstruct the front with respect to the air outlet 10, and the upper edge of the airflow guide plate 12 is integrally connected to the lower edge of the backrest 3 b of the seat 3 at the deployed position.

Therefore, when the airflow guide plate 12 is deployed, the conditioned air blown from the air outlet 10 at an angle of 45 ° flows as shown by the arrow in FIG.
, And ascends along this slope, is taken over by the back of the backrest 3b, further ascends to the upper space of the seat 3 using this surface as a guide, and ascends to the sky while taking in the breath and the like exhaled by the audience. Since the air is exhausted through the ventilation holes provided on the ceiling side or the like, the air can be quickly replaced without stagnation of the air flow near the seat 3 or unnecessary convection.

That is, in this case, the backrests 3b of the individual seats 3 can be fully utilized as open ventilation guides.

The air flow guide plate 12 can be folded and stored on the bottom surface of the seat plate 3a as shown in FIG. 2 by operating means (not shown) against the spring pressure of the spring 16.

In this case, the air blown out from the outlet 10 passes through the lower surface of the seat plate 3a as shown by the arrow in the figure.
The conditioned air can be blown directly to the feet of the spectators sitting on this.

Therefore, this case is suitable for local heating, for example, when the entire building cannot be heated, such as in an open stadium in winter. The air-conditioned air that has flowed through the feet of the spectators hits the backrest 3b of the seat 3 located one step below the front of the spectators, and uses this as a guide to ascend and ventilate.

As an operation unit for folding and unfolding the airflow guide plate 12, the airflow guide plate 12 is provided beside the seat 3.
It is also possible to provide a lever or the like that cooperates with the system so that the spectator can operate it arbitrarily, or it can be set semi-fixed to one of the folding and unfolding modes according to the air conditioning mode.

FIGS. 3 and 4 show a second embodiment of the present invention. The same portions as those in the first embodiment are denoted by the same reference numerals, and only the different portions will be described using different reference numerals.

That is, in this embodiment, the floor slab 20 directly constitutes a stepped passenger seat, and the horizontal plane 20a and the vertical plane 20b are alternately and continuously formed with a predetermined step. The seat 3 is fixed via the pillar 4.

Inside each vertical surface 20b, a partition wall 21 surrounding the vertical surface 20b is formed integrally with the vertical surface 20b in a rectangular shape, and the space surrounded by the partition wall 21 is conditioned by air-conditioned air parallel to the vertical surface 20b. And the air outlet 10 for the conditioned air is opened in the vertical surface 20b.

Therefore, the conditioned air flowing in the direction of the arrow in parallel with each vertical surface 20b blows out through the outlet 10, collides with the airflow guide plate 12 set on the pillar 4 as shown by the arrow, and follows the inclination. As it rises and is taken over by the back of the backrest 3b, it further rises to the upper space of the seat 3 using this surface as a guide, and in the meantime, rises to the sky while taking in the breath etc. of the audience, and is dissipated or provided on the ceiling side etc. The exhaust will be exhausted through the ventilation holes.

[0031]

As described in the above embodiments, in the air-conditioning structure for a staircase-shaped passenger seat according to the present invention, the conditioned air blown horizontally from the vertical surface of the floor hits the airflow guide plate, Ascending along this surface and the back of the continuous backrest, this rising airflow is slightly ahead of the landing surface of the spectator's feet, so that the airflow does not come into contact with dust or the like adhering to the floor, There is an advantage that quick ventilation can be performed without causing stagnation in the vicinity of the customer seat, since the airflow is not hindered by touching or airflow.

Further, since a configuration collapsible airflow guide plate to the bottom surface of the seat plate, by folding the airflow guide plate, such as during heating toward the seat pan, conditioned air blowout between the pedestal to the front Since the foot portion is directly heated, it is suitable for local heating in a case where the entire building cannot be heated, such as in an open stadium.

Further, even when the floor is integrated with the floor slab, the inside of each vertical surface is surrounded by a partition wall to form an air supply passage for conditioned air parallel to the vertical surfaces, and In this configuration, the air outlet of the conditioned air is opened, so that this kind of air conditioning structure can be adopted.
