Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a pyrotechnic device that emits an explosive sound and is used as a trigger for a Kratzker or as a firecracker.

[Conventional technology]

In general, traditional Kratzker pull balls and firecrackers are
As shown in Figure A, a strip of thin paper P is charged with an explosive a, and the thin paper P is moved as shown in Figure 3C with a drawstring or fuse W placed as a core in contact with the explosive a as shown in Figure 3B. It was manufactured by winding it up and gluing the end of the roll. (Hereinafter, this is referred to as a paper-wrapped firework.)

In addition, there is also known a pull ball for Kratzker with a structure as shown in Fig. 4, in which female and male male and female mating bodies D and E made of plastic are filled with explosives and the explosives are detonated by pulling the pull string F. There is. (below,
This is called a plastic Hikidama).

[Problem that the invention attempts to solve]

However, the conventional paper-wrapped firework shown in FIG. 3 requires skill in the paper-wrapping operation, and has the problem of being time-consuming and expensive to manufacture. Also, the fourth
The plastic pull ball shown in the figure is not only expensive because it uses resin-molded female and male mating bodies D and E, but also causes the plastic male and female mating bodies D and E to explode as shown in Figure 4B. The problem is that it is very dangerous because it splits into two parts in its original form and pops out of the Kratzker cylinder (not shown).
Until now, it has not been put into practical use at all.

[Means for solving problems]

In order to solve the above-mentioned conventional problems, this invention provides a firework body used as a trigger for a cracker or a firecracker with a shaped notch 1a at the center position on one side and the shaped notch 1a at the center position on the other side. A center bending line 1c provided with a latching claw 1b that is bent and engaged with the center bending line 1c.
A mount 1 made of cardboard that can be folded into two, an explosive 2 charged at the center of the mount 1, and one end of the mount 1 joined to the charged part of the explosive 2 along the center bending line 1c. A drawstring or fuse 3 is attached so as to extend outward from the end, and after the drawstring or fuse 3 is attached, the mount 1 is folded in half,
It is characterized in that the latching claw 1b is constructed by bending and engaging with the shaped notch 1a.

[Effect]

In the smoke body of this invention, an explosive 2 that produces an explosive sound is charged to the center of the surface of a mount 1 as shown in Fig. 1B, and then a drawstring or fuse 3 is attached to the charged part of the mount as shown in Fig. 1C. After attaching the drawstring or fuse 3, fold the mount 1 in half from the center bending line 1c as shown in FIG. It is manufactured by bending and engaging as shown in the figure.

〔Example〕

Hereinafter, an embodiment of this invention will be described in detail with reference to the drawings in FIGS. 1 and 2. In the figure, 1 is provided with a shaped notch 1a at the center position on one side, and the shaped notch 1a at the center position on the other side. A mount 1a is provided with a hook 1b that is bent and engaged, and the mount 1 is made of cardboard with a thickness of about 0.5 mm and a size of about 15 x 15 mm.
It is formed so as to be folded in half from the center bending line 1c. The latching claw 1b is formed of a lip-shaped protrusion whose tip width is wider than the notch width of the shaped notch 1a, and the width of the bent part of the claw is approximately equal to the width of the shaped notch 1a.

Reference numeral 2 denotes an explosive that produces an explosive sound and is charged in the center of the surface of the mount 1. One end of a drawstring or fuse 3 is placed on the charging portion of the explosive 2 as shown in FIG. 1C. The drawstring or fuse 3 is attached so as to extend outward from the end of the mount 1 along the center bend line 1c of the mount 1.

After the drawstring or fuse 3 is attached as shown in FIG. 1C, the mount 1 is folded in half from the center bending line 1c through the process shown in FIG. By bending it downward and engaging it with the shaped notch 1a, the parts shown in Fig. 1E and Figs.
A firework body is constructed as shown in the figure.

[Effect of idea]

Since the smoke body of this invention has the above-mentioned structure, an explosive 2 that produces an explosive sound is loaded in the center of the surface of the mount 1 as shown in Figure 1B, and then a drawstring is attached to the charged part of the mount. Alternatively, place the fuse 3 as shown in Figure 1C, and after attaching the drawstring or the fuse 3,
Fold it in half from the center bending line 1c as shown in Figure 1D, and attach the hook 1b to the cutout 1a.
It can be manufactured by a simple operation of simply bending and engaging the fireworks as shown in FIG.

Moreover, since the main body of the smoke body of this invention is formed by the cardboard mount 1, the main body mount 1 will be broken into pieces and scattered when the explosive 2 explodes. It does not have the dangers of plastic pull balls, and has the advantage of being safe to use.
