Description

[Detailed Description of the Invention] (Industrial Application Field) This invention is applicable to facilities equipped with an extremely large number of seats, especially seats made of flammable synthetic resin, such as multipurpose halls, gymnasiums, stadiums, and baseball stadiums. The present invention relates to a seat that is suitably implemented, and more particularly to a seat that has been improved to prevent the spread of combustion and the spread of fire in the early stages of a fire.

(Prior Art) Most of the seats in multipurpose halls and the like are made of synthetic resin, such as the seat boards and backrests, which are molded from highly flammable high-density polyethylene.

By the way, when it comes to multi-purpose halls, etc., of course, thorough measures must be taken to prevent fires, prevent fires from spreading, and prevent the spread of fire, but there are still some points where it cannot be said that the measures taken regarding the seating areas are perfect.

In other words, the floor of the seat is often littered with flammable paper scraps, etc., and finding a source of ignition, such as a lit cigarette or wet electricity on the floor of an unpopular seat, is usually However, if such a spark were to ignite waste paper and cause a fire, it would quickly spread to the easily flammable seats, causing the combustion to spread rapidly and cause a large fire.

Therefore, when it comes to seats made of synthetic resin in multi-purpose halls and the like, it is important to devise ways to prevent the spread of combustion and fire, especially in the early stages of a fire.

(Purpose of the Invention) Therefore, the purpose of the present invention is to fill the combustible seat with the synthetic resin that melts and melts at the early stage of a fire when paper scraps scattered on the floor of the seat catch fire. When the main extinguishing agent is poured out, the extinguishing agent covers not only the synthetic resin that has fallen onto the floor, but also the burning paper scraps that are the source of the fire below, which of course prevents the spread of the fire and the spread of the fire. Another object of the present invention is to provide seats made of synthetic resin for multipurpose halls, etc., which are expected to extinguish fires and are improved so as to prevent fires in facilities and conflagrations.

(Structure of the Invention) In order to achieve the above object, the synthetic resin seat in a multipurpose hall etc. according to the present invention has a synthetic resin seat plate, a backrest, etc., which are the constituent elements of the seat, formed into a hollow structure, The hollow part is filled with powder, granular, liquid, or gas extinguishing agent.

(Example) Further, a detailed explanation will be given based on the illustrated embodiment.

FIG. 1 shows a general structure of seats in a multipurpose hall or the like. That is, the seat plate 1 made of synthetic resin and the backrest 2 are each attached between legs 3.3 made of cast iron that are fixed and erected on the floor of the hall. The backrest 2 is normally fixed, but the seat plate 1 is rotatably attached to the shaft 5 of the leg 3 via an arm 4 attached to its lower surface, making it convenient for cleaning floors.

By the way, the seat plate 1 and the backrest 2 (including any other armrests made of synthetic resin, of course) are usually made of high-density polyethylene and are blow-molded to have a hollow structure, as shown in Figure 2. , which ensures elasticity. A fire extinguishing agent 6 is filled in the hollow portion.

As the extinguishing agent 6, powder or granular materials of known ingredients that are currently used in fire extinguishers are conveniently used. However, in extreme cases, it may be liquid or gaseous.

It is also possible to use water. In addition, the hollow
It is also preferable that the interior of the section is divided into appropriate sizes by partitions 7, so that the extinguishing agent 6 is poured out one after another depending on the degree of progress of combustion.

In any case, according to the seat configured as described above, for example, the second
As shown in the figure, paper scraps 9 scattered on the floor 8 of a hall etc. catch fire and burn up, and the flames reach the flammable seat plate l.
If the melt falls from the heated seat plate l, the fire extinguishing agent 6 filled therein will simultaneously pour out and sprinkle on the source of the fire directly below.

Therefore, it is expected that the fire extinguisher 6 will extinguish the burned paper waste 9 and the fallen synthetic resin.

Furthermore, even if the fire is not completely extinguished, it can be expected to have sufficient effects in suppressing the spread of combustion and the spread of the fire to the seats.

Therefore, for example, if it is an indoor facility, you can expect that there will be enough time for the smoke detectors that are always installed to activate and start the fire extinguisher, so at least you can be sure that there will be no fire that will cause a big fire. It can be prevented.

Similar effects can be expected for seats in outdoor facilities.

(Operation and Effect) As explained in detail above in conjunction with the examples,
According to the synthetic resin seats in multi-purpose halls and the like of this invention, in the early stages of a fire that ignites paper scraps scattered on the floor of the facility and starts burning, the fire spreads to the easily flammable synthetic resin seats one after another and burns. It can reliably prevent the fire from expanding and spreading, and in some cases, it can even be expected to have a complete fire extinguishing effect.

Therefore, seats made of flammable synthetic resin in facilities such as multi-purpose halls with a large number of seats can be expected to be effective as an important measure for fire prevention, fire prevention, and prevention of fire spread.
