Description

【0001】
【発明の属する技術分野】
本発明は玩具花火に関するものである。
【0002】
【従来の技術】
玩具花火としては、軸の一端に火薬を塗着してなるスパークラー、筒状体内に火薬を充填してなるススキ等が従来より使用されている。これらの玩具花火における火薬中にアルミニウム粉、マグナリウム粉等の金属粉を混入したときには、これらの金属粉が燃焼しつつ落下することにより火花が発生することも知られている。
【0003】
【発明が解決しようとする課題】
しかるに、上記従来の玩具花火における金属粉による火花は、単に「火の粉」状の火花が燃焼しつつ落下するに過ぎないため、面白味に欠ける嫌いがあることは否定できないものである。
【0004】
このような状況に鑑み、本発明は、燃焼時に多数の火球が落下しつつ爆発するようにした新規な玩具花火を提供しようとしてなされたものである。
【0005】
【課題を解決するための手段】
上記課題を解決するために、本発明は下記の玩具花火を提供する。
【0006】
(1)火薬中に酸化鉄と硫黄とを含ませてなり、該火薬の燃焼時に酸化鉄と硫黄とを含む火球が飛散し、各火球が空中で爆発して火花を放出し、***して小火球となり、各小火球が再び爆発して火花を放出するようにしたことを特徴とする玩具花火(請求項1)。
【0007】
【作用】
[請求項1の玩具花火]
火薬に点火すると、火薬が燃焼し、酸化鉄(粉末)と硫黄とを含む火球(符号11参照。)が飛散する。硫黄は融点が119℃と非常に低いため、低温で液相となり、酸化鉄の内側に入り込み、火球の核(符号13参照)となる。火球は空中で爆発して***し、小火球(符号11’参照)となる。各小火球においても硫黄は酸化鉄の内側に入り込んで該小火球の核(符号13’参照)となる。各小火球は再び爆発する。図3参照。各火球はこのようにして空中で爆発する際に線香花火の如く火花を放出する。空中における各火球の爆発による火花は極めて鮮明であり、あたかも多数の線香花火の火球が空中で火花を発しているかの如き様相を呈する。図2参照。
【0008】
【発明の実施の形態】
次に、本発明の実施の形態を添付図面に従って説明する。
図1は本発明による玩具花火の一例たるスパークラーを示すものである。同図において、符号1に示すものは軸である。軸1は一例として木製とする。
【0009】
軸1には不燃剤3を固着する。固着は浸漬その他如何なる手法によるものであってもよい。不燃剤3は火薬部の嵩を大きくするために軸1に固着されるものである。因みに、玩具花火1本当りの火薬使用量は法令により規制されている。不燃剤3の組成の一例を下記に示す。
木粉 35.0重量%
炭酸カルシウム 30.0重量%
顔料 5.0重量%
でんぷんのり 30.0重量%
【0010】
不燃剤3上に火薬5を塗着する。塗着は浸漬その他如何なる手法によるものであってもよい。なお、軸1に直接火薬を塗着することが本発明に含まれるむことはいうまでもない。火薬5の組成の一例を下記に示す。
硝酸カリウム 46.0重量%
硝酸バリウム 6.0重量%
過塩素酸カリウム 5.0重量%
硫黄 15.0重量%
雑炭 10.0重量%
アルミニウム 1.0重量%
酸化鉄 5.5重量%
マグナリウム 1.5重量%
でんぷんのり 10.0重量%
【0011】
前記硝酸カリウムと硝酸バリウムと過塩素酸カリウムは酸化剤である。前記硫黄と酸化鉄は前述の如き作用をなす。前記雑炭は可燃剤である。前記アルミニウムは温度を上昇させるための発熱剤であって極めて細かな粉末である。前記マグナリウムは音を発すると共に金色の炎色を出す。前記でんぷんのりは火薬を固めるために使用されるものである。
【0012】
前記火薬5の先端に点火剤7を塗着する。塗着は浸漬その他如何なる手法によるものであってもよい。点火剤7の組成の一例を下記に示す。
過塩素酸カリウム 42.5重量%
硝酸バリウム 17.0重量%
炭酸カルシウム 7.5重量%
アルミニウム 3.0重量%
ヴィンソールレジン 8.5重量%
木粉 5.0重量%
マグナリウム粉 1.5重量%
でんぷんのり 15.0重量%
【0013】
前記火薬5の表面に燃焼調節被膜9を設ける。燃焼調節被膜9としては、例えば水性塗料の被膜、紙の被膜、ポリエチレン、ポリプロピレン等の合成樹脂の被膜等が使用される。燃焼調節被膜9は点火剤7の表面にも設けてもよい。
【0014】
火薬の表面に設けた燃焼調節被膜は火薬を均一且つ確実に燃焼させるものである。因みに、燃焼調節被膜がない場合には、火薬の表面に沿って火が急速に走るおそれもあり得る。
【0015】
前記火薬にマグナリウム又はチタンを加えてもよい。マグナリウム(粉末)は火薬の燃焼時に音を発すると共に金色の炎色を出す。チタン(粉末)は火薬の燃焼時に音を発すると共に銀白色の炎色を出す。

【発明の効果】
[請求項1の発明]
火薬の燃焼時に酸化鉄と硫黄とを含む火球が飛散して空中で爆発する際に線香花火の如く火花を放出する。空中における各火球の爆発による火花は極めて鮮明であり、あたかも多数の線香花火の火球が空中で火花を発しているかの如き様相を呈する。従って、請求項1の玩具花火は従来の玩具花火では到底得られない面白味と美しさとを有するものである。

BACKGROUND OF THE INVENTION
The present invention relates to toy fireworks.
[0002]
[Prior art]
Conventionally used as toy fireworks are sparklers in which explosive is applied to one end of a shaft, and skies in which a cylindrical body is filled with explosives. It is also known that when metal powders such as aluminum powder and magnalium powder are mixed in the explosives in these toy fireworks, sparks are generated by dropping these metal powders while burning.
[0003]
[Problems to be solved by the invention]
However, it is undeniable that the sparks of metal powder in the conventional toy fireworks are merely sparks of “sparks” and fall while burning, so that there is an unpleasant dislike.
[0004]
In view of such a situation, the present invention has been made in order to provide a novel toy fireworks in which a large number of fireballs explode while falling.
[0005]
[Means for Solving the Problems]
In order to solve the above problems, the present invention provides the following toy fireworks.
[0006]
(1) Iron powder and sulfur are included in the gunpowder. When the gunpowder burns, a fire ball containing iron oxide and sulfur scatters, and each fire ball explodes in the air to release a spark and break up. A toy fireworks characterized in that each small fireball explodes again and emits a spark .
[0007]
[Action]
[Toy fireworks of claim 1]
When the gunpowder is ignited, the gunpowder burns and a fireball (see reference numeral 11) containing iron oxide (powder) and sulfur is scattered. Since sulfur has a very low melting point of 119 ° C., it becomes a liquid phase at a low temperature, enters inside iron oxide, and becomes the core of a fireball (see reference numeral 13). The fireball explodes in the air and splits into a small fireball (see reference numeral 11 '). Also in each small fireball, sulfur enters inside the iron oxide and becomes the core of the small fireball (see reference numeral 13 '). Each small fireball will explode again. See FIG. Each fireball thus emits a spark like a sparkler when it explodes in the air. The sparks from the explosion of each fireball in the air are very clear, and it looks as if many sparkler fireballs are sparking in the air. See FIG.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 shows a sparkler as an example of toy fireworks according to the present invention. In the figure, what is indicated by reference numeral 1 is an axis. The shaft 1 is made of wood as an example.
[0009]
A flame retardant 3 is fixed to the shaft 1. The fixing may be performed by immersion or any other method. The incombustible agent 3 is fixed to the shaft 1 in order to increase the bulk of the explosive part. Incidentally, the amount of explosive used per toy fireworks is regulated by law. An example of the composition of the flame retardant 3 is shown below.
Wood powder 35.0% by weight
Calcium carbonate 30.0% by weight
Pigment 5.0% by weight
Starch paste 30.0% by weight
[0010]
The explosive 5 is applied on the incombustible agent 3. The coating may be performed by dipping or any other method. Needless to say, the present invention includes applying explosive directly to the shaft 1. An example of the composition of the explosive 5 is shown below.
Potassium nitrate 46.0% by weight
Barium nitrate 6.0% by weight
Potassium perchlorate 5.0% by weight
Sulfur 15.0% by weight
Coal 10.0% by weight
Aluminum 1.0% by weight
Iron oxide 5.5% by weight
Magnarium 1.5% by weight
Starch paste 10.0% by weight
[0011]
The potassium nitrate, barium nitrate and potassium perchlorate are oxidizing agents. The sulfur and iron oxide perform the above-described action. The miscellaneous coal is a combustible agent. The aluminum is a heat generating agent for raising the temperature and is a very fine powder. The magnalium emits a sound and produces a golden flame. The starch paste is used to harden gunpowder.
[0012]
An ignition agent 7 is applied to the tip of the explosive 5. The coating may be performed by dipping or any other method. An example of the composition of the ignition agent 7 is shown below.
Potassium perchlorate 42.5% by weight
Barium nitrate 17.0% by weight
Calcium carbonate 7.5% by weight
Aluminum 3.0% by weight
Vinsole resin 8.5% by weight
Wood flour 5.0% by weight
Magnarium powder 1.5% by weight
Starch paste 15.0% by weight
[0013]
A combustion control coating 9 is provided on the surface of the explosive 5. As the combustion control coating 9, for example, a water-based coating, a paper coating, a synthetic resin coating such as polyethylene or polypropylene, or the like is used. The combustion control coating 9 may also be provided on the surface of the igniter 7.
[0014]
The combustion control coating provided on the surface of the explosive is for burning the explosive uniformly and reliably. Incidentally, if there is no combustion control coating, there is a possibility that the fire may run rapidly along the surface of the explosive.
[0015]
Magnalium or titanium may be added to the explosive. Magnalium (powder) emits a sound when burning explosives and produces a golden flame. Titanium (powder) emits a sound when explosives burn and produces a silvery white flame.
[0016]
【The invention's effect】
[Invention of Claim 1]
When a fire ball containing iron oxide and sulfur scatters and explodes in the air when explosives are burned, a spark is emitted like a sparkler. The sparks from the explosion of each fireball in the air are very clear, and it looks as if many sparkler fireballs are sparking in the air. Therefore, the toy fireworks of claim 1 have the fun and beauty that cannot be obtained with conventional toy fireworks.
[0017]
[Brief description of the drawings]

FIG. 2 is a perspective view showing a combustion state of the toy fireworks.
FIG. 3 is an explanatory view schematically showing a combustion mode of the toy fireworks.
