Description

[Detailed description of the device] [Industrial field of application] This device is based on Russian roulette
It's about playable crackers.

[Conventional technology]

BACKGROUND ART Conventionally, a cracker is generally known in which explosives such as explosives and small tapes are contained in a cracker cylinder, and the front end opening of the cylinder is closed by an explosion release lid.

[Problems to be solved by the device]

Since the conventional cracker is configured to explode the explosive body housed in the cylinder by pulling the drawstring, an interesting Russian that explodes the explosive body by manually rotating the rotating operation body as appropriate.・ I was not able to play roulette and there was a problem of lack of interest.

This invention has been devised to solve the above-mentioned conventional problems, and its purpose is an interesting Russian that explodes explosives by manually rotating the rotary operation body at the rear end of the cylinder as appropriate.
It is to provide highly interesting crackers that can play roulette.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the cracker of the present invention stores explosives 7 such as explosives 7 and small winding tape in a cracker cylinder 1 and uses an explosive detachment lid 3 at the front end opening of the cylinder 1. In the closed one, the explosive exterior portion of the explosive body 7 is fixed in the cracker cylinder 1 so as not to rotate, and the string or rod extending from the explosive portion of the explosive body 7 is appropriately twisted to make explosive charge. It is formed of a hard cord 9 or a plastic rod 9a having a small diameter that can transmit a rotational force to the portion, and the hard cord 9 or the plastic rod 9a is manually turned to the outer end portion extending from the cylindrical rear end hole 1a. The rotary operating body 10 is fixed, and the explosive body 7 is exploded by rotating the rotary operating body 10 by hand to cause rotational friction in the explosive portion.

[Action]

According to the cracker having the above-described structure, it is possible to perform an interesting Russian roulette play in which the rotary operation body 10 at the rear end of the tubular body 1 is appropriately manually operated to explode the explosive body 7.

〔Example〕

Hereinafter, a first embodiment of the present invention will be specifically described with reference to the drawings of FIGS. 1 and 2. In the figure, reference numeral 1 is a cylindrical cracker cylinder integrally molded of synthetic resin. This cracker cylinder 1 has a partition wall 2 inside the rear end, and an explosive release formed by styrene foam etc. at the front end opening. The lid 3 is fitted and fixed so that the lid 3 can be exploded and removed. Reference numeral 4 denotes a pressure receiving plate fitted in the cylindrical body 1, and a ejecting substance 6 such as a small tape is stored in a cylindrical body empty chamber 5 between the pressure receiving plate 4 and the explosion separation lid 3.

Reference numeral 7 denotes a paper-wrap type explosive body housed inside the rear end of the cylindrical body 1, and the explosive body 7 is formed by adhering the explosive exterior portion to one surface of the cylindrical partition wall 2 with an adhesive tape 8. It is fixed so as not to rotate in 1. The string 9 extending from the explosive part of the explosive body 7 is formed of a hard string that can be appropriately twisted to transmit a rotational force to the explosive part,
A hand-operated rotary operation body 10 is fixed to the outer end portion of the rigid string 9 extending from the cylindrical body rear end hole 1a, and the explosive portion is connected to the rotary operation body 10 by a half rotation to one rotation operation. The explosive body 7 can be exploded by causing rotational friction.

FIG. 3 shows a cracker according to a second embodiment of the present invention, in which the explosive body 7 is fixed to the inner wall portion of the rear end of the cracker body 1 with an adhesive tape 8 instead of the hard cord 9. A plastic rod 9a having a small diameter capable of appropriately transmitting the rotational force to the twisted explosive portion is provided, and a knob-shaped rotary operating body is provided at an outer end portion of the plastic rod 9a extending from the cylindrical rear end hole 1a. 10a is integrally provided, and this rotary operation body 10a
It is different in that it is configured so that the explosive body 7 can be exploded by causing rotational friction in the explosive portion by a manual operation of about 10 to 20 degrees. Other configurations and operations are the same as those in the first embodiment. is there.

FIG. 4 shows a cracker according to a third embodiment of the present invention, in which the cracker cylinder 1 has a conical shape, and a conical-shaped explosive holding body 11 is fitted inside the rear end of the cracker. The explosive body 7 is adhered and fixed to the inside of the body 11 with the adhesive tape 8, and the conical-cylinder-shaped rotary operating body 10b is fitted to the outer peripheral portion of the rear end of the conical-shaped cylindrical body 1. A hard string (10) capable of properly transmitting a rotational force to the explosive portion on the outer periphery is bent and joined and adhesively fixed with an outer paper (12),
It is different from the first embodiment in that it is configured so that the explosive body 7 can be detonated by causing a rotational friction in the explosive portion by a manual operation of rotating 10b in one or two rotation positions. It is the same.

FIG. 5 shows a cracker according to a fourth embodiment of the present invention, in which the cracker cylinder 1 has a conical shape, and a disk-shaped powder carrier 13 is fitted inside the rear end thereof.
The explosive body 7 is adhered and fixed to the upright plate portion 14 of 13 with the adhesive tape 8, and the disk-shaped rotary operation body 10c is adhered and fixed to the rear end extending portion of the hard string 9, and the rotary operation body 10c It is different in that the explosive body 7 can be detonated by causing rotational friction in the explosive portion by a manual operation of about two rotations, and other configurations and operations are similar to those of the first embodiment. .

[Effect of device]

Since the cracker of this invention has the above-mentioned structure, it has an effect of being able to perform an interesting Russian roulette play of exploding the explosive body by manually rotating the rotary operation body at the rear end of the cylinder appropriately. Therefore, it is possible to provide a cracker that is more interesting than the conventional one.
