Description

  The present invention relates to a launcher for rocket fireworks, and more particularly to a launcher for rocket fireworks used for repelling harmful birds and beasts.

  Devices and tools using rocket fireworks have been invented and devised to repel harmful birds and beasts that damage crops and the like. The repelling by rocket fireworks is to make the harmful birds and beasts leave the place by threatening the harmful birds and beasts with sound and light and flying objects from the launch of rocket fireworks. Because the opponent is a harmful bird and beast, it is desirable in terms of work safety that rocket fireworks can be launched as far as possible.

  As a rocket fireworks launching tool used for repelling harmful birds and beasts, a devised design that focuses on safety and the range of rocket fireworks (flying distance) is known with the name of the device being “fireworks gun” (Patent Document 1). ). This device has a structure in which a rocket fireworks insertion port and a lead wire holding part are provided in a substantially central part of the cylinder body, and a cover part through which the cylinder body can be inserted is provided, while the lead wire is provided outside the cylinder body. The rocket fireworks can be completely put into the cylinder. For this reason, while having safety in the ignition to the lead wire and the launch of the rocket fireworks main body, although it is a short time until it jumps out of the cylinder, the launch direction and launch angle of the rocket fireworks are guided by the cylinder, It is easier to determine the firing angle than the conventional pistol type that ignites the rocket fireworks head part (chamber part) from the cylinder, and the range of the rocket fireworks may also increase. .

  Another rocket fireworks launcher was to provide a safe and inexpensive tool that can be carried anywhere, can respond instantly when encountering harmful birds and animals, and can be handled easily. The invention is known (Patent Document 2). The invention relates to a rocket fireworks having a hard cylindrical shape as a barrel, an insertion and launch port for a rocket fireworks or the like, an opening provided in the middle of the barrel as an ignition port, and a gripping portion at the top of the gun barrel Etc. is a launching device. Since this invention also fires rocket fireworks completely in the cylinder, there is a possibility that the flight distance of rocket fireworks can be extended by adjusting the angle of the barrel.

  However, rocket fireworks using the tools according to these inventions / inventions, even if there is an increase in flight distance, are only due to the use of the device / tool, and the flight distance is increased by the configuration of the device / tool itself. It is not.

Utility Model Registration No. 3124484 JP 2007-97564 A

The problem to be solved by the present invention is to increase the flight distance of rocket fireworks by the structure of the rocket fireworks launcher.
If the flight distance of rocket fireworks can be extended, it will be possible to stay closer to harmful birds and beasts than before, and it will also ensure safety in repelling operations.

The invention of the present application is characterized in that, in a rocket firework launcher having a cylindrical body, a container body is attached to one end of the cylindrical body.
The invention according to claim 1 has a cylindrical body having both ends opened and a container body that is elastically deformed, and joins an open portion at one end of the cylindrical body to an opening of the container body. This is a rocket fireworks launcher. The rocket fireworks that ignite the lead are put into the cylinder and fired.
The elastic deformation refers to a deformation in which an object deformed by an external force completely returns to its original shape when the external force is removed.
As the container body that elastically deforms, for example, an aluminum or resin container can be considered. The shape of the container is not particularly limited, but a container having a bottom surface orthogonal to the extension line on the extension of the cylinder is desirable. You can divert aluminum bottles and plastic bottles that are sold with drinks.

The reason why the flight distance of the rocket fireworks is extended by the configuration of the present invention is presumed as follows.
From the ignited lead, the gunpowder of the rocket fireworks burns to generate gas. Rocket fireworks fly with this propulsion force as this gas blows out backwards. The elastically deformable container body provided behind the cylinder body expands by receiving the propulsive force of the rocket fireworks, and then pushes out the air inside the container to return to the original shape, and urges the rocket fireworks at the time of launch. As a result, I think that the distance of the rocket fireworks will be extended. Alternatively, it is assumed that the pressure wave generated by the combustion gas from the rocket fireworks is reflected in the container body and assists the launch of the rocket fireworks.

The invention according to claim 2 is characterized in that, in the rocket fireworks launching device according to claim 1, the container body is detachable.
As a configuration that allows detachment, the screw that fits into the joint part of the cylinder and the container body is cut and fitted, or the screwed small part is attached to the cylinder and the screw part provided on the container body is fitted. Can be considered. In this case, if the aforementioned aluminum bottle is used, it is not necessary to cut the screw on the container body side. Or it is good also as a structure which pinches | interposes and fixes the whole or a part of container body.

  The invention according to claim 3 is the rocket fireworks launching tool according to claim 1 or 2, wherein the elastically deforming container body is made of aluminum. The term “aluminum” means that aluminum or an aluminum alloy is used as the main coverage. As described above, as an easily available aluminum container, there is an aluminum bottle that is sold in a state where a beverage is placed.

  The invention according to claim 4 is the rocket fireworks launching tool according to claim 1, claim 2, or claim 3 in which at least one gripping portion is provided on the cylindrical body. The gripping part may be a rod-like part or a gun grip. In addition, the gripping portion can be attached to the cylinder by welding, fitting, a method using an attachment band, or the like.

According to the rocket launching tool of the present invention, the range of the rocket fireworks is increased, so that the distance from the harmful birds and beasts can be increased more than ever. Longer distances from harmful birds and beasts will ensure the safety of repelling work.
In addition, since most of the burning debris of the conducting wire used for igniting the rocket fireworks is received in the container body, most of the burning debris is not scattered, and there is an advantage that it is good for the natural environment.

  According to the second aspect of the present invention, since the container body can be detached, it can be disassembled and carried. In addition, there is an advantage that even if the container body is damaged due to the use of the rocket fireworks launching tool according to the present invention several times or the impact when carrying it, it can be easily replaced with another container body. Furthermore, when throwing away the burning residue of the conducting wire accumulated in the container body, there is also an advantage that the burning residue of the inside conducting conductor can be discarded by removing the container body from the cylindrical body.

  The invention according to claim 3 uses an aluminum bottle as a container body that is elastically deformed. However, if a commercially available product containing a beverage is used as the aluminum bottle, the container body can be easily obtained. Moreover, it is not necessary to cut a screw for connection with a cylinder.

  According to the fourth aspect of the present invention, there is an advantage that it is easy to determine the launch direction of the rocket fireworks by holding and holding the gripping portion.
