Description

[Detailed Description of the Invention] This invention relates to a connected chair for seating multiple people, which is mainly installed and used in theaters, etc., and particularly relates to a connected chair with a louver that also has an indoor air conditioning function.

Conventionally, in theaters and other theaters where a large number of connected chairs are arranged on the floor, a ventilation pine room is erected on the floor directly below the seats of the connected chairs for air conditioning, and a ventilation passage such as a duct is installed under the floor at the bottom of the pine room. Air conditioning was achieved by connecting the air conditioner and blowing out cooling/heating air or clean air, or conversely, sucking and discharging contaminated indoor air.

However, in the case of using the above-mentioned pine room, the connecting chairs are installed on the floor so as to straddle the pine room, so installation is troublesome, and the multiple support legs of the chair and the pine room are located under the seat of the connected chair. Because of this, the structure is complicated, the floor is difficult to clean, dirt tends to accumulate, and it is unsanitary and unsightly.

Therefore, in recent years, efforts have been made to integrate the matsushi room, which is essential for the equipment of theaters, etc., with the supporting legs of connecting chairs. In other words, the supporting legs of the connected chair are made hollow to communicate with the ventilation passage piped from under the floor, and a large number of ventilation holes are formed in the peripheral wall of the hollow supporting legs, so that air for air conditioning can be discharged from the ventilation holes of the supporting legs or indoors. By sucking and exhausting contaminated air, the above-mentioned conventional problems can be solved.

However, when the supporting legs of the above-mentioned pine room are integrated, the supporting legs are first made hollow and a large number of ventilation holes are formed in the surrounding wall, so the strength to support the load as the supporting legs of the connected chair becomes a problem.
It becomes necessary to construct the supporting legs from a very thick and strong material, which increases the cost, and since the amount of air discharge or suction is determined by the opening amount of the ventilation holes in the supporting legs, priority should be given to the strength of the supporting legs. It is not possible to reduce the number of ventilation holes or reduce the hole diameter, and at the same time, the height of the supporting legs from the floor needs to be higher than a certain level. For example, if the seat of each seat is made of thick cushion, Since the seating height cannot be changed, the supporting legs are shortened, but
In such cases, there were drawbacks such as problems in securing the volume of discharge and suction air.

This idea was devised in view of the above circumstances, and its purpose is to not only clean the floor, but also to eliminate problems such as selecting the strength and height of the supporting legs, and to be able to discharge or suction at the desired air volume. To provide a connected chair with a louver that can achieve very good air conditioning in a room such as a theater.

In other words, this idea makes the supporting legs of the connected chair hollow and communicates with the ventilation passages such as pipes under the floor, but without forming any ventilation holes in the peripheral wall of the supporting legs, the hollow square pipes are hung horizontally on the upper ends of the supporting legs. It has a configuration in which a ventilation louver is provided in an opening provided in the middle of the horizontal rod, and air conditioning air is passed through the horizontal rod arranged horizontally under the seat and from the louver in the middle. This is a connected chair with a louver that can effectively discharge contaminated air or suction and exhaust indoor contaminated air.

An embodiment of this invention will be described below with reference to the drawings. First, Figures 1 and 2 show a connected chair for seating multiple people installed on floor A of a theater, etc., and the lower end leg base 1a is fixed to the upper surface of floor A with bolts or the like, so that it tilts slightly backward. A plurality of supporting legs 1 are each erected in the state, and a horizontal connecting rod 2 is horizontally suspended in a bridge shape by welding or the like on the upper ends of these supporting legs 1.
A plurality of side plates 3, which also serve as armrests, are erected and fixed on the horizontal rod 2 at equal intervals in the longitudinal direction.
The seat 4 is constructed between each of the side plates 3, and each seat can accommodate one person at a time. Each of the seats 4 has an automatic flip-up seat 5 which is pivotally supported between the side plates 3 so as to be able to stand up and fall down, and a side plate 3 on the rear side which is also fixedly installed between the side plates 3 and stands slightly tilted backwards. It has a backrest 6 that rises. Further, each of the side plates 3 is fixed by welding the lower rear side to the horizontal rod 2 as shown in FIGS. 3 to 5, and is attached and fixed to a plate 7 such as a steel plate erected as a core material. ing.

Here, in the above-described connected chair, the supporting legs 1 and the horizontal rods 2 are each formed into a hollow shape. That is, as shown in FIGS. 3 and 4, the support leg 1
is made of a square steel tube so as to be hollow across the upper and lower ends, and a communicating hole 1a' is also formed in the leg base 1a welded to the lower end of the leg base 1a, so that the floor A can be connected from the bottom of the floor A.
It is connected so as to coincide with and communicate with the upper end of a ventilation passage B for discharging or suctioning air conditioning air, or for both purposes, which penetrates the upper surface. In addition, it is preferable to interpose an annular sealing material (not shown) such as a film between the lower end leg base 1a of the supporting leg 1 and the upper surface of the floor A to prevent air leakage.

On the other hand, the connecting horizontal rod 2 is made of a hollow square pipe such as a square steel tube as described above, and both ends thereof are closed with caps (not shown), etc., and are fixed by welding to the upper end of the supporting leg 1 on the lower surface. A communication hole 2a that coincides with and communicates with the upper end opening of the support leg 1 is formed in the lower portion. That is, the horizontal rod 2 is internally communicated with the support leg 1.

Further, the hollow connecting horizontal rod 2 is divided in the middle as shown in FIG. 3, and a connecting channel material 8 of an appropriate length made of channel steel is provided to connect the two. Furthermore, the channel material 8
Both ends are the cut end faces 2 of the horizontal rod 2 divided above.
It is integrated with the horizontal rod 2 so that it functions as a part of the horizontal rod 2 by fitting it from above so as to overlap the portions of appropriate length near b and 2b and connecting them by welding. . By dividing the horizontal rod 2 and connecting the channel member 8 with an open bottom surface, a louver mounting opening 9 is formed which extends horizontally and opens downward between both cut end surfaces 2b, 2b of the horizontal rod 2. Then, a horizontally long ventilation louver 10 is installed and installed in the opening 9, and the support leg 1 is installed from under the floor A.
The air conditioning air, such as cooling/heating or clean air, which is forced into the horizontal rod 2 through the inside of the louver 10
It is possible to blow out indoor air, or conversely, suck indoor contaminated air through the louver 10 and exhaust it from the inside of the horizontal rod 2 through the support leg 1 to the outside from the underfloor ventilation path.

As shown in FIG. 8, the ventilation louver 10 has a pair of oblong front and back plate parts 11a having an arcuate cross section and a plurality of screw holes 11a' on the inner surface, and a hanging plate part 11b connected to the lower part of the plate part 11a. Closing plates 12, 12 are screwed to both ends of the drawn-out molded members 11, 11, forming a horizontally elongated gutter shape with the upper and lower surfaces open as a whole. By slidingly fitting pivot pins 14, 14 such as rivets protruding from angle-shaped mounting plates 13, 13 disposed on both outer ends into the formed mounting holes 12a, 12a, the mounting holes 12a, 12a are supported so as to be rotatable around the horizontal axis. The structure is as follows. Both cut end surfaces 2 of the horizontal rod 2 are divided into two mounting plates 13, 13 as shown in FIG.
By attaching the louver 1 to the lower side of b and 2b with screws 15 and 15, as shown in FIGS. 6 and 7,
0 is rotatably mounted so that substantially the upper half thereof is accommodated in an opening 9 formed by a channel material 8. Note that 16, 16 are sealing materials such as filters attached to the inner surfaces of the front and rear plates of the channel material 8 by adhesive or the like.
On the arcuate inner surface of the louver 10, the cross-sectional arcuate plate portions 11a, 11 of the front and rear drawn members 11, 11 of the louver 10 are provided.
a is in sliding contact.

Thus, the louvered connected chair having the above-described structure is installed on the floor A so that the supporting legs 1 are in communication with the ventilation passage B of the floor A. With this, for example, an air conditioner (not shown) installed outside the building can
When air-conditioning air such as heating air or clean air is pumped through the floor under the floor, the air-conditioning air rises through the hollow support leg 1 of the connected chair and flows from the inside of the support leg 1 into the hollow rectangular pipe-shaped horizontal rod 2. Air is blown out from the louver 10 to the lower side of the seat 4 through the louver 10. At this time, since the louver 10 has a horizontally elongated air outlet, the air blown out from the louver 10 is widely diffused to the lower side of the connected chair seat 4, and the airflow is directed from the lower side of the seat 5 to the front and backrest. 6, the air flows upward from the rear side of the seat 6, reducing the discomfort caused by air concentration at the feet of the seated person.
Good indoor air conditioning will be achieved. Note that when air is blown out with the louver 10 facing straight down as shown in Fig. 6, due to the air volume etc.
If a problem such as dirt rising up on the top surface occurs, try to solve the above problem by rotating the louver 10 to tilt it forward or backward as shown in Figure 7, and change the air blowing method appropriately. In this way, for example, cold air or warm air can be actively blown out toward the front or rear of the seat.

Conversely, when using an exhaust fan installed outside the building to suck and exhaust indoor contaminated air,
The louver 10 acts as a suction port for contaminated air and the horizontal rod 2
From there, the air is sucked into the interior of the support leg 1, and then exhausted to the outside through the ventilation path B and under the floor.

It is more effective to provide one or more rectifying plates (not shown) in the longitudinal middle of the louver 10 so that the air can be blown out evenly without being biased.

Since this invention has been developed as detailed above, there is no need for a pine room set up on the floor, making it easy to clean the floor, and since there are no ventilation holes in the supporting legs, there are no problems with the strength and height selection of the supporting legs. The support legs are made of inexpensive material and can be set to any height that prioritizes the height of the seat, and the air can be discharged or sucked at the desired volume, making it extremely effective for air conditioning indoors such as theaters. be.
