BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to chairs installed at places where an unspecified number of spectators use the stands, such as baseball stadiums, athletics stadiums, gymnasiums, etc., and seats in multipurpose halls. The present invention relates to a chair using a seat plate.

[0002]

2. Description of the Related Art A large number of chairs for spectators, which are arranged in a large number on stands, seats, etc., have rigid legs erected on the floor, and a seat plate and a backrest are placed between the left and right legs. There are many simple types with a The seat plate is of a flip-up type that is automatically raised and rotated by a spring force or the like when a seated person leaves the seat from a substantially horizontal state where the seat can be seated, and the backrest is fixedly provided in a slightly backward tilted state. Is common.

The legs of such seats are made of metal such as cast iron. However, the seat plate and the backrest are made of synthetic resin because of ease of manufacture and reduction of cost. There are many FRP molded articles or blow molded articles made of organic materials such as polyester and polyethylene.

[0004]

[Problems to be Solved by the Invention] By the way, in places such as baseball stadiums, athletics stadiums, gymnasiums, etc., which are used by an unspecified number of spectators such as stands and multipurpose halls, newspapers discarded on the floor by spectators. There is a danger that a cigarette fire may ignite a paper waste such as a paper waste or a garbage waste such as a Styrofoam container, causing a fire. Therefore, it is natural that fire prevention and fire spread prevention measures must be taken to prevent such fires. However, the fire prevention measures for the grandstand chair itself cannot be said to be perfect.

That is, as described above, the seat plate and backrest of the seat for the grandstand are often made of synthetic resin such as a flammable FRP molded product or a blow molded product made of an organic material such as polyester or polyethylene. So, when the garbage discarded on the floor below it ignites with a cigarette fire and burns up, it immediately burns to the nearest flammable synthetic resin seat plate, and then leans back. There is also a danger that the fire spreads to the chair next to it and may cause a fire. However, because of the nature of the seats and backrests of the current grandstand chairs made of organic materials as described above, the modification of materials that bring the degree of flammability to the so-called nonflammability is the current situation. It is impossible with technology.

The present invention has been made in view of the above-mentioned circumstances, and the object thereof is that, despite the use of a flammable synthetic resin seat plate, garbage and the like are flared up on the lower floor surface. Even providing a chair excellent in fire prevention measures that can prevent burning out to the seat plate immediately, greatly delay the spread of fire, increase the evacuation time of the audience, and minimize the disaster. It is in.

[0007]

In order to achieve the above object, the chair of the present invention has the same structure as a seat plate made of a synthetic resin member.
At least one of the surfaces of the chair body having a backrest
It is characterized in that a non-combustible coating is provided on the part .

[0008]

According to the chair having the above-mentioned structure, assuming that garbage or the like burns on the floor on which the chair is placed , the chair body may
Because at least part of the surface has a non-combustible coating,
The guard has been that of suppression of extend itself is fire in this non-flammable coating
It takes a considerable amount of time for the garbage to extinguish naturally or to ignite the seat plate and spread the fire even if it is not the case. This will save you time to evacuate and minimize disasters.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. First of all, Fig. 2 is a simplified chair for a grandstand installed at places such as baseball stadiums, athletics stadiums, gymnasiums, etc. and seats in multipurpose halls used by an unspecified number of spectators.
The entire body 1a is shown. Here, a single chair is illustrated, but the same applies to a connected chair having a plurality of seats in a horizontal row. In the figure, reference numeral 1 denotes a pair of left and right legs which are also erected on the floor and also serve as side plates, 2 denotes left and right legs 1, and a seat plate mounted so as to lie substantially in the middle between the right and left, 1; The backrest is disposed at a rearward position above the plate 2 in a slightly inclined state. The seat plate 2 is rotatably mounted between the left and right legs 1 and 1 via pivots 5 projecting from the left and right frames 4 shown in FIG. When the occupant leaves the seat, it is of a flip-up type that automatically rises and turns due to spring force or the like. The backrest 3 includes the left and right legs 1,
1 is fixed to a substantially upper half portion of the rear side surface by appropriate means.

The left and right legs 1, 1 are made of a highly rigid metal such as cast iron. The seat plate 2 and the backrest 3 are each made of a synthetic resin, particularly a synthetic resin molded product such as a flammable FRP molded product or a blow molded product (integral hollow molded product) made of an organic material such as polyester or polyethylene. In this state, if the garbage discarded on the lower floor is burned by a cigarette or the like, the seat plate 2 is ignited, which is a problem in disaster prevention. Therefore, as shown in FIG. A non-combustible coating 6 is provided on the lower surface (range from substantially the rear half of the seat lower surface to the rear end rising surface, which is located on the lower side because it is an automatic flip-up type). The non-combustible coating 6 is formed by spraying a metal such as aluminum on the seat plate 2 or applying an inorganic material such as ceramic.

However, if the chair is configured as described above,
Despite the use of the flammable synthetic resin seat plate 2, even if refuse or the like burns on the lower floor surface, at least the lower surface of the seat plate 2 is sprayed with a metal or an inorganic material. Since the non-combustible coating 6 coated with is applied, the fire is not immediately transferred to the seat plate 2 by being guarded by the non-combustible coating 6, and the garbage and the like are naturally extinguished.
Even if it is not the case, it takes a considerable amount of time to ignite the seat plate and spread the fire, and in the meantime, somebody notices and extinguishes the fire and can prevent the spread of fire, or gain enough time for the spectators to evacuate with a margin and minimize the disaster Will be kept to a minimum.

According to the experimental results, when a newspaper of about 300 g is put on the floor just below the center of the seat plate 2 of the chair and ignited, the conventional (current) blow-molded chair made of polyethylene uses the newspaper. After ignition, the fire spread to the lower end of the seat in 1 minute and 15 seconds, spread to the lower end of the back in 7 minutes and 0 seconds, and the seat and back were completely burned in about 20 minutes. In the chair in which the non-combustible coating 6 was applied to the lower surface of No. 2, no fire spread occurred even when about 300 g of the newspaper was burned out.

[0013] Moreover, such a chair having excellent nonflammability is
Simply providing the non-combustible coating 6 on the outer surface of the chair body 1a,
It is possible to simply give fire-resistant performance to the flammable chair body 1a.
it can. Although the non-combustible coating 6 is provided on the lower surface of the seat plate 2 (range from substantially the rear half of the seat lower surface to the rear end rising surface), the present invention is not limited to this, and the entire lower surface of the seat plate 2 is provided. May be provided on the lower surface of the backrest 3.

[0014]

[Effect of the invention] According to the chair of the invention, for example, the chair is
Even if the floor in the dust debris blazed wither, the chair body
Since at least a part of the surface may incombustible coating, this <br/> guarded incombustible coating fire can be prevented from proceeds example retardant, significantly delaying the ignition flame spread time, the audience evacuation time Excellent effects can be obtained in fire prevention measures that can earn and minimize disasters. In addition, provide a non-combustible coating
Can provide fire protection to the flammable chair itself.
