本案は、少数の電線で多数の花火に着火する花
火点火回路に関する。[Detailed Description of the Invention] The present invention relates to a fireworks ignition circuit that ignites a large number of fireworks using a small number of electric wires.
この種従来の花火点火回路としては、第１図に
示すように、点火玉イと呼ばれる花火への着火装
置に各々電線ロを継いで、電源側へ接続する回路
が多く用いられている。 As shown in FIG. 1, conventional fireworks ignition circuits of this type often include a circuit in which a device for igniting fireworks called an ignition ball is connected to a power source by connecting electric wires to each device.
この回路は第１図においては単純であるが、実

玉数＋１本の電線が必要であり、まだ充分ではな
かつた。 This circuit is simple in Figure 1, but since actual fireworks are launched in the hundreds to thousands of rounds, the number of ignition balls required for various types of fireworks, such as launching, setting, and waterfalls, is from several tens to several thousands. There are over 100 fireworks, and because the fireworks display site is divided into several locations, the work of connecting the numerous electric wires from each site to the power source is complicated and requires a lot of manpower. Wrong wiring can cause fireworks to ignite unexpectedly, resulting in a dangerous situation that can lead to personal injury, so it is necessary to carefully check the wiring after wiring to ensure safety. Because of the large number of power lines involved, preparing fireworks for launch required a lot of manpower and time. In order to reduce the number of wires, a common negative wire was used as shown in Figure 2, but this still required the number of igniters plus one wire, which was still not sufficient.
本案は以上のような事情に鑑みて為されたもの
であり、ごく少数の電線による配線で多数の花火
に自在に着火する花火点火回路を提供せんとする
ものである。 This proposal was made in view of the above circumstances, and is intended to provide a fireworks ignition circuit that can freely ignite a large number of fireworks with only a small number of electrical wires.
本案の実施例につき第３図乃至第４図に基づき

本案の点火回路Ａは以上のように構成するか

各点火玉端子１に点火玉イを接続した後、例えば
プラスラインL3とマイナスラインLCを多芯ケー
ブルか従来の電線を経て電源Ｅに接続すると、電
源ＩはプラスラインL3、ダイオード４、点火玉
イを通りマイナスラインLCに流れる。 Since the ignition circuit A of the present invention is constructed as described above, in its use, after connecting the ignition ball A to each ignition ball terminal 1 as shown in Fig. 5, for example, the positive line L 3 and the negative line When line L C is connected to power source E via a multi-conductor cable or conventional wire, power source I flows through positive line L 3 , diode 4, and ignition ball A to negative line L C.

マイナスラインLA，LB，LC，LD，LE，LFの選択
組み合せによつて、指定座標位置にあるいずれの
点火玉イでも自在に通電可能となる。 At this time, a diode 4 is interposed in the positive direction on the positive terminal 3 side of each ignition ball terminal 1, and the terminals of the other positive lines L 1 , L 2 and the other negative lines L A , L B are open. , the current I flows to the other ignition ball A.
It is possible to energize only one scheduled ignition ball A at the coordinate point target position without causing any current to flow. That is, in the fireworks ignition circuit A of the present invention, the positive lines L 1 , L 2 , L 3 , L 4 , L 5 , L 6 , L 7 , L 8 , L 9 , L 10 and the negative lines L A , L B , By selecting a combination of L C , L D , L E , and L F , it is possible to freely energize any ignition ball A located at the specified coordinate position.
ここで、本案の花火点火回路における電線数と
点火玉端子の関係を示すと、
Ｎ＝（ｎ−１）×１
Ｎ：点火玉端子数
ｎ：電線数
ｌ：マイナスライン数
となる。仮に電線数ｎを40本とし、そのうちのマ
イナスライン数ｌを20本とすれば（40−20）×20
＝400個の点火玉端子群に選択通電自在とするこ
とができる。これを第１図の回路で行うとすれば
400×２＝800本、第２図の回路でも400＋１＝401
本の電線が必要であり、本案の花火点火回路が、
多数の点火玉端子に対して極めて少数の電線によ
る配線で済むことが判る。 Here, the relationship between the number of electric wires and the ignition ball terminal in the fireworks ignition circuit of the present invention is shown as follows: N=(n-1)×1 N: number of ignition ball terminals n: number of electric wires 1: number of minus lines. If the number of wires n is 40 and the number of negative lines l is 20, then (40-20) x 20
= 400 igniter terminal groups can be selectively energized. If this is done using the circuit shown in Figure 1,
400 x 2 = 800 lines, even the circuit in Figure 2 is 400 + 1 = 401
A real electric wire is required, and the proposed fireworks ignition circuit is
It can be seen that only a very small number of wires are required for wiring a large number of igniter terminals.
本実施例では専らダイオードをプラスラインと
各プラス端子間に介接した場合について述べてき
たが、このダイオードは予定の点火玉に流れた電
流が予定外の点火玉には流れないようにしている
のであつて、各マイナス端子とマイナスライン間

スラインを逆とした場合にはダイオードの向きも
逆方向に接続するのは当然である。 In this embodiment, we have exclusively described the case where a diode is interposed between the positive line and each positive terminal, but this diode prevents the current flowing to a scheduled ignition ball from flowing to an unscheduled ignition ball. Therefore, the diodes may be connected between each negative terminal and the negative line, and if the positive line and the negative line are reversed, it is natural that the diodes should be connected in opposite directions.
以上述べてきたように、本案の花火点火回路は
従来の花火点火回路が多数の電線を必要としてい
たのに対し、ごく少数の電線に集約化、省約化さ

化、確実迅速化、安全化を大きく達成するという
優れた実用性、有用性を発揮する。 As mentioned above, whereas conventional fireworks ignition circuits require a large number of wires, the proposed fireworks ignition circuit is consolidated into a very small number of wires, saving energy and connecting more igniter terminals. It can be selectively energized, and by reducing the number of wires, it has excellent practicality and usefulness, as it greatly reduces labor, increases reliability, speeds up reliability, and improves safety in the preparation work for fireworks launches. demonstrate.
