Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a flame-colored ornamental firework set containing a plurality of solid combustion agents that ignite and burn to produce beautiful flame-colored flames.

[Conventional technology]

Conventionally, a fireworks composition prepared by adding and mixing a flame coloring agent and a pyrotechnic agent to metaldehyde, and a solid combustion agent for fireworks obtained by molding and solidifying this fireworks composition into an appropriate shape are disclosed in Japanese Patent No. 129124.
This is known as the technology disclosed in Japanese Patent Publication No. 60-12314 (Japanese Patent Publication No. 60-12314), and uses a solid combustion agent for fireworks disclosed in the same patent publication, and this solid combustion agent is fitted and held on a combustion stand. The technology of ignition and combustion was also developed in 1984-84400.
It is published as an improved idea in the publication No.

The conventional composition for fireworks and the solid combustion agent for fireworks made by molding and solidifying the composition emit beautiful flame-colored flames and sparks when ignited and burnt, burn beautifully for a long time, and create an elegant atmosphere. It has excellent ornamental properties, is non-hazardous and can be used safely indoors, is smokeless and produces very little odor or toxic gas, and does not scatter residual pickles and contaminate the surrounding area. It is possible to obtain excellent effects.

[Problem to be solved by the invention]

However, since the conventional solid combustion agents are ignited one by one using a matchstick, lighter, etc., for example, multiple solid combustion agents that generate flames and sparks of different flame colors such as red, yellow, and green are set up. set like fireworks,
There was a problem in that it was not possible to ignite and burn continuously.

By the way, as a continuous ignition method for continuously igniting and burning a plurality of objects to be combusted, such as candles, a technique using a filamentous combustion fuse such as nitrocellulose is disclosed in, for example, Japanese Patent Publication No. 60-27122 and is generally known. However, since this combustion fuse is connected and fixed with adhesive in contact with the candle combustion wick, if this candle ignition method is applied to the continuous ignition of solid combustion agents as described above,
The following problems arise.

■ Since the solid combustion agent does not have a combustion wick like a candle, when connecting a fuse to this solid combustion agent, the combustion fuse should be brought into contact with the surface of the solid combustion agent, which is the object to be combusted, and fixed with adhesive. For this reason, the combustion fuse comes into close contact with the surface of the solid combustion agent, and combustion air (oxygen) does not enter the part where the fuse is in close contact with, so even if the fuse is ignited, the ignition combustion of this fuse There is a problem in that the flame weakens at the part that comes in contact with the combustion agent, and the solid combustion agent does not ignite effectively.

■ The combustion residue of the fuse adheres to the surface of the combustion agent,
There is a problem in that it adversely affects the flame color reaction of solid combustion agents, and the beautiful flame color inherent to the combustion agents specified in firework compositions cannot be produced.

■ If the fuse is connected and fixed to the surface of the solid combustion agent with adhesive, the installation of the fuse is not only troublesome, but also difficult.
There is a problem in that the surface of the solid combustion agent peels off due to the shrinkage effect when the adhesive dries, causing the fuse once attached to come off later.

This invention was made to solve the above-mentioned conventional problems, and its first purpose is to place a plurality of solid combustion agents on the base body that produce beautiful flame-colored flames, similar to fireworks. To provide a flame-colored ornamental firework that can be set to ignite and burn continuously. Moreover, the second aspect of the present invention

In addition, the preferred combustion fuse in the present invention includes a plurality of combustion fuses having a large combustion area, each having a mounting hole that is inserted into the combustion stand and having a large combustion area that burns at a position below the solid combustion agent, and each of the combustion fuses having a large combustion area. It is preferable to use a celluloid thin plate consisting of a thin strip-shaped fuse that integrally connects the parts, and in this case, the mounting hole is inserted into the combustion stand and fixed with adhesive. It is desirable to form a gap between the squib combustor and the solid combustion agent to introduce a sufficient amount of combustion air.

Furthermore, in the present invention, as the next preferred combustion fuse, it is preferable to use a nitrocellulose (nitrocellulose) filament having ignited ends. The fuse is wound one turn or several times around a plurality of combustion stands so as to extend laterally from the stand position at one end, and is then glued to ensure sufficient space between the fuse winding and the solid combustion agent. What is necessary is to form a gap portion for introducing a certain amount of combustion air. Further, in the present invention, the combustion stand is preferably constructed of a metal stand consisting of a base plate portion and a stud pin protruding from the base plate portion, although the structure thereof is not particularly limited. In this case, the base body on which the plurality of combustion stands are erected and fixed has eight boxes having an ashtray function and having a depth shallower than the protruding height of the stud pins, and a plurality of stud pin insertion holes. It is composed of an inner bottom plate that is laid and fixed to the inner bottom of the thin box so as to sandwich a stand base plate part, and the stand base plate part is sandwiched between the middle bottom plate and the thin box bottom plate to form a thin box base. A stand structure in which the stud pin is placed upright on the body can be applied.

If it emits flames and sparks of different flame colors such as green,
By continuously igniting this solid combustion agent with a fuse and simultaneously burning it, an elegant atmosphere can be created by different colored flames and sparks such as red, yellow, and green, and an excellent ornamental quality can be obtained.

■ The combustion fuse is set in the combustion stand so that it is spaced below the solid combustion agent, and the combustion residue on the fuse falls to the bottom, which prevents deterioration of the flame color reaction due to combustion residue on the combustion fuse. In addition, by introducing a sufficient amount of combustion air into the gap formed between the fuse ignition combustion part and the solid combustion agent, the combustion fuse can be ignited and burned well, and multiple pieces of solid combustion can be ignited and burned. The agent can be reliably ignited continuously.

■ When the fuse is formed of a thin celluloid plate and a fuse with a wide combustion area is provided in the part of the celluloid thin plate fuse located under the solid combustion agent, the fuse runs through the narrow strip-shaped fuse. Since the combustion flame burns largely below the solid combustion agent, the solid combustion agent can be ignited more reliably, and the problem of poor ignition of the combustion agent can be solved. A similar effect can also be achieved when a nitrocellulose filament fuse is sequentially wound once or several times around a combustion stand and bonded to form a fuse winding part. .

■ The base body that stands and fixes multiple combustion stands is
