Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a hanging-type cracker that is hung by hand and used.

[Conventional technology]

A conventional cracker is configured such that a cracker body containing an explosive body is directly held in a hand and the explosive body is exploded by a triggering operation or a pulling operation of a drawstring.

[Problems to be solved by the device]

Since the conventional cracker is used by directly holding the cracker body containing the explosive body in a hand, high safety in use is required, and there is a problem that the main body cannot store a sparking sounding explosive body as a set. there were.

An object of the present invention is to provide a hanging type cracker that can be safely used even if a sparking pyrotechnic body is set.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the hanging-type cracker of the present invention comprises a long suspending cord 1 having a hollow body retaining portion 1a at a lower end thereof, and a hollow body retaining portion of the suspending cord 1. Explosive body 2 which is provided at the upper part of the retaining portion close to 1a and explodes due to relative sliding friction with the suspension cord 1, and a string outlet hole 3 of the suspension cord 1 and an explosive gas of the explosive body 2 on the outer peripheral portion. A hollow body 5 that is hung from the suspension cord 1 with the peripheral portion of the cord extraction hole 3 abutting on the end face portion of the explosive body 2 that has the hole 4 and is stored inside, and the suspension cord of the hollow body 5. 1 has a center through hole 6 loosely inserted in 1 and is provided with an impact drop body 7 which is gravitationally dropped from above by using the hanging string 1 as a guide. It is characterized in that the explosive body 2 is exploded by the action of handling the explosive body by impact inertia.

The explosive body 2 may be a sounding explosive body producing only a large explosive sound, or a sounding explosive body producing innumerable sparks simultaneously with a large explosive sound. The hollow body 5 is a hollow sphere having a large number of gas vent holes 4 on the outer periphery thereof, and a sparking explosive body 2 for spark generation is set and housed therein. In this way, when the explosive body 2 is exploded by the fall of the impact falling body, the spark a generated by the explosive body 2 is radially ejected from the gas vent hole 4 of the hollow sphere 5 and a beautiful spark ball is emitted. Appears for a moment, making it more entertaining than the one that only produces an explosion sound.

[Action]

The cracker having the above structure is used by holding the end portion of the long hanging strap 1 by hand and suspending the hollow body 5 of the sounding portion so as to be separated from the body. Then, the explosive body 2 is exploded by the explosive body handling action due to the impact inertia of the impact falling body 7.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. This hanging type cracker is used by holding the end portion of the long hanging string 1 by hand and suspending the hollow body 5 of the sounding portion away from the body, and the hollow body retaining portion 1a at the lower end. With a long length and a hollow body retaining portion of the hanging strap 1.
Explosive body 2 which is provided at the upper part of the retaining portion close to 1a and explodes due to relative sliding friction with the suspension cord 1, and a string outlet hole 3 of the suspension cord 1 and an explosive gas of the explosive body 2 on the outer peripheral portion. Hollow body 5 that is hung from the hanging strap 1 with the peripheral portion of the string outlet hole 3 in contact with the end face portion of the explosive body 2 that has the vent hole 4 and is housed inside
And a center through hole 6 loosely inserted in the hanging string 1 of the hollow body 5.
And the impact falling body 7 which is gravitationally dropped from above by using the hanging string 1 as a guide.

The hanging string 1 is made of a strong paper string having a length of, for example, about 90 cm, and the hollow body retaining portion 1a at the lower end thereof is formed of a string knot for preventing the hollow body 5 from falling. The explosive body 2
Is a winding ball in which a sounding explosive 2a that comes into frictional contact with the hanging string 1 is wrapped with a wrapping paper 2b. This winding ball sounding explosive 2a may have only a large explosion sound, but in the present embodiment, In some cases, it is considered to be a sounding explosive mixed with a spark agent that produces a large explosion sound and countless sparks a.

The hollow body 5 is a hollow sphere having one stringing hole 3 and a large number of small-diameter gas vent holes 4, and is a pair of upper and lower halves.
It has a structure in which 5a and 5b are coupled by fitting the opening edge portions. The impact drop body 7 is a sphere having a weight of about 50 g, and the lead core body 8 is made of a soft or hard synthetic resin 9
It has a spherical structure covered with.

The cracker having the above-mentioned structure holds the end portion of the long suspending string 1 by hand and suspends the impact-falling body 7 in a use state as shown in FIG. 1 in which the hollow body 5 of the sound producing portion is suspended so as to be separated from the body. When the string 1 is dropped as a guide, the explosive body 2 is exploded by the explosive handling action due to the impact inertia of the impact falling body 7, and the spark a generated by the explosive body 2 is a hollow sphere 5 as shown in FIG.
A beautiful fireball, which emits sparks radially from the degassing hole 4 of FIG.

[Effect of device]

Since the cracker of this invention is of the hanging type as described above, it has the effect that it can be safely used even if a sparking sounding explosive body is set, and in particular, a large number of gas vent holes are provided. When a set of sparking explosives that generate sparks is stored in the hollow sphere, the sparks generated by the explosives radiate out from the gas vent holes of the hollow spheres, and beautiful sparks of sparks appear for a moment. Therefore, it can be more entertaining than a pronunciation cracker that only produces explosion sounds.
