Description

【考案の詳細な説明】〔産業上の利用分野〕本考案は、打揚煙火やその部品等に使用する伝
火薬付導火線に関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a fuse with a transfer charge for use in launching fireworks and their parts.

[Conventional technology]

打揚煙火および打揚玉の部品容器等に使用され

黒色系火薬による伝火薬が導火線端末に取付けら
れている。以下にこのような導火線を図面を用い
て説明する。 As a method of preventing misfires and misfires in the fuses used in parts containers for launchers and launchers, a transfer charge, mainly made of black gunpowder, is attached to the fuse end. Such a fuse will be explained below using drawings.

る。 FIG. 2 is a cross-sectional view. In the figure, 1 is a fuse, and the core 2 is covered with a protective layer 3. 4 is a transfer gunpowder, which is wrapped in thin paper 5 such as Japanese paper. The method for attaching the transfer powder 4 to the fuse 1 is to place a small amount of the transfer powder 4 on a small piece of thin paper 5, apply adhesive around the end of the fuse 1,
The ends of the thin paper 5 on which the transfer charge 4 is placed are wrapped around the adhesive surface to form an integral body.

[Problem that the invention attempts to solve]

以上のような従来技術によると、この薄紙の中
の伝火薬をこぼさないようにして導火線の接着剤
面に接着させる作業は非常に困難であつて生産性
が悪く、しかも接着剤を導火線の端部に塗布する
際に導火線の芯薬が吸湿し、伝火薬を取付けたが
吸湿による失火が起きたりして事故を起す虞れが
あつて取扱いに非常な厳格さが要求される。 According to the above-mentioned conventional technology, it is extremely difficult and difficult to attach the transfer powder in the thin paper to the adhesive surface of the fuse without spilling it, and the productivity is low. The core of the fuse absorbs moisture when it is applied to the area, and even if the transfer agent is attached, there is a risk of misfire due to moisture absorption and an accident, so extremely strict handling is required.

[Means for solving problems]

本考案は、導火線の端部に伝火薬を載せた薄紙
をスリーブによつて取付けて一体としたことを特
徴とする。 The present invention is characterized in that a thin paper carrying a transfer charge is attached to the end of the fuse using a sleeve to integrate the fuse.

[Effect]

以上の構成によると、スリーブの内周に薄紙の
周囲を接触させるようにして器状に形成し、この
中に伝火薬を入れ、その後導火線の端部をスリー
ブ内に圧入して一体にしたものであり、伝火薬を
こぼすことも無く製作が容易であると共に接着剤
を用いないために芯薬が吸湿することが無く不測
な事故を起すことも無くなることになる。 According to the above structure, the periphery of the thin paper is brought into contact with the inner periphery of the sleeve to form a container shape, the transfer charge is placed inside the container, and then the end of the fuse is press-fitted into the sleeve and integrated. Therefore, it is easy to manufacture without spilling the transfer powder, and since no adhesive is used, the core powder does not absorb moisture, eliminating the possibility of unexpected accidents.

〔Example〕

以下に本考案の実施例を図面を用いて説明す
る。第１図は断面図であり、１は導火線であり、
芯薬２のまわりを保護層３で囲んでいる。５は和
紙等の薄紙であり、中に黒色系火薬等による伝火
薬４が封入してある。 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view, and 1 is a fuse;
The core drug 2 is surrounded by a protective layer 3. 5 is a thin paper such as Japanese paper, and a transfer powder 4 made of black gunpowder or the like is sealed therein.

６は上記導火線１と薄紙５を一体に締着するス
リーブであり、アルミニウムやしんちゆう等の非
鉄金属製もしくはプラスチツク製であり、このス
リーブ６によつて導火線１端部に伝火薬４を包ん
だ薄紙５が一体に取付けられている。 Reference numeral 6 denotes a sleeve that fastens the fuse 1 and the thin paper 5 together, and is made of non-ferrous metal such as aluminum or steel, or plastic, and the sleeve 6 wraps the transfer charge 4 around the end of the fuse 1. A thin paper 5 is attached integrally.

このような構成にする製造方法の１例を説明す
る。 An example of a method of manufacturing such a structure will be described.

まずスリーブ６の内周面に薄紙５を器状にして
その端部周面を接触させて伝火薬４を入れる。 First, a thin paper 5 is made into a container shape and the transfer powder 4 is placed in contact with the end circumferential surface of the sleeve 6 .

このようにしたスリーブ６の開放端側から導火
線１の端部を圧入して導火線１と、薄紙５に包ま
れた伝火薬４とを一体にするものである。 The end of the fuse 1 is press-fitted from the open end side of the sleeve 6 so that the fuse 1 and the transfer charge 4 wrapped in the thin paper 5 are integrated.

また、第２の製造方法例としては、伝火薬４を
つつんだ薄紙５の端部を導火線１の端部に巻き、
薄紙５側からスリーブ６を導火線１の端部の薄紙
５を重ねた処まではめて全一体としたものであ
る。 In addition, as a second manufacturing method example, the end of the thin paper 5 enclosing the transfer powder 4 is wrapped around the end of the fuse 1.
The sleeve 6 is fitted from the thin paper 5 side to the end of the fuse 1 where the thin paper 5 overlaps to form a whole.

いずれにせよ、導火線１の端部に、伝火薬４を
包んだ薄紙５の端部をスリーブ６によつて固定し
て一体にしたものであればよい。 In any case, it is sufficient that the end of the thin paper 5 enclosing the transfer charge 4 is fixed to the end of the fuse 1 with a sleeve 6 to be integrated.

[Effect of idea]

以上説明した本考案によると、導火線の端部に
伝火薬を包んだ薄紙を一体に取付けるに際してス
リーブによつて一体にすることにより、導火線の
端部周囲に接着剤を塗布する必要が無く、この接
着剤の塗布による導火線芯薬の吸湿が無くなり、
この吸湿によつて生ずる失火や事故の虞れが無く
なることになる。 According to the present invention described above, when the thin paper wrapped with the transfer charge is attached to the end of the fuse, it is integrated with a sleeve, so there is no need to apply adhesive around the end of the fuse, and this Moisture absorption of the fuse core chemical due to adhesive application is eliminated,
This eliminates the risk of misfires and accidents caused by this moisture absorption.

また、製造に際しても薄紙に包んだ伝火薬をこ
ぼすことも無く作業性にすぐれるものである。 Furthermore, during manufacturing, the transfer powder wrapped in thin paper does not spill, and the workability is excellent.
