Description

  The present invention relates to a signal bullet emission device that can be emitted to the sky without using a signal handgun or the like.

Conventionally, when a signal bullet is fired, for example, a signal bullet is mounted on a handgun-type dedicated launching device, and the signal bullet is fired at an appropriate time by operating a trigger or the like.
Moreover, in order to make it easy to carry, for example, there is a signal bullet emitting device formed in a rectangular parallelepiped shape that can be held with one hand (see, for example, Patent Document 1). This launching device is configured such that when carrying, a device body in which signal bullets are arranged is stored in a safety cover, and when the signal bullets are fired, the device body is slid and pulled out from the safety cover.
The safety cover is provided with an operation lever. When the operation lever is operated, the firing pin mechanism portion operates, and the detonator is detonated by the firing pin to fire the signal bullet.
This launching device is configured to launch a signal bullet provided in the device main body in a direction perpendicular to the pulling direction (sliding direction) of the device main body. When it is housed, the launch port of the signal bullet is covered with the side wall of the safety cover.

Further, there is a signal bullet provided with an ignition powder, a propellant, a time delay drug, a release drug, etc. in order from the bottom inside a cylinder provided with a signal bullet at the tip (see, for example, Patent Document 2).
This signal bullet is fixed to a signal bullet emission device installed on a flat surface, and a predetermined current is passed through an ignition leg connected to the ignition charge, and the signal bullet is emitted to the sky.
When a current flows through the ignition leg, the igniter in the cylinder is ignited, and combustion of the propellant is started by this ignition. As the propellant burns, the cylinder with the signal bullet at the tip rises upward, and the ignition charge burns over a predetermined time by the ignition of the ignition charge and spreads to the release charge.
The fire spread of the released medicine occurs while the cylinder rises to the sky, and when the released medicine ignites, a signal bullet is released from the inside of the cylinder.

FIG. 2 is an explanatory view showing a mode of carrying the signal bullet emitting device of FIG. This figure shows a state when the user or the like carries the signal bullet emitting device 1 and shows a longitudinal section in this state.
The signal bullet firing device 1 is configured such that the firing cylinder 10 and the grip cap 9 including the firing needle mechanism unit 11 can be attached and detached only by a user's hand operation without using a tool or the like. Has been. When the signal bullet launcher 1 is shipped from the factory or carried by a user or the like, as shown in FIG. 2, the grip cap 9 is inserted into the insertion hole provided at one end of the grip cap 9. It will be in the state.

In order to prevent the launch tube 10 from easily falling off from the grip cap 9 in this state, for example, an appropriate frictional force is generated at the contact portion between the outer wall of the launch tube 10 and the inner wall of the insertion hole of the grip cap 9. The outer wall of the firing tube 10 and the surface of the inner wall of the grip cap 9 insertion hole are configured (processed).
Alternatively, for example, notches and taps are provided at both ends of the insertion hole of the grip cap 9 and the notches and taps are engaged with the outer wall of the launch tube 10 or the outer side of the casing of the firing mechanism 11. The grip cap 9 and the launch tube 10 may be engaged with each other with appropriate strength, and may be configured to be easily detachable.

In the signal bullet emitting device 1 in the state shown in FIG. 2, removable plugs 12 and plugs 13 are attached and fixed to seal the openings of the aforementioned insertion holes at both ends of the grip cap 9. The embolus 12 seals the opening on the side where the launch tube 10 is inserted (stored) as will be described later, and the embolus 13 seals the opening on the side where the above-mentioned firing mechanism unit 11 is installed.
Thus, by sealing the insertion hole portion of the grip cap 9, it is possible to increase the moisture and dust proofing effect inside the grip cap 9 and to obtain the effect of suppressing the deformation of the signal bullet emitting device 1 when dropped. You can also. The material of the emboli 12 and 13 may be the same as that of the above-mentioned firing tube embolus 6, but may be softer than the firing tube embolus 6 because it does not require strong adhesion.

That is, the tip of the launch tube 10 is disposed on the back side of the grip cap 9 insertion hole, and the tip of the launch tube 10 is sealed by the embolus 13 via the firing pin mechanism 11, and the rear end of the launch tube 10 (the detonator 2 is connected). The installed bottom surface side) is blocked by the embolus 12. Therefore, in the state shown in FIG. 2, the propellant 4, the postponement drug 3, the bullet 5 and the like installed in the bore of the launch tube 10 seal the tip of the launch tube 10 as described above. The tube embolus 6 and the grip cap 9 covering the launch tube 10 are not touched (or strongly suppressed) by the outside air.
Note that the rear end side of the launch tube 10 is moisture-proofed by the detonator 2 as described above, and the intrusion of outside air or the like is suppressed by the embolus 12 together with the detonator 2. Therefore, for example, even when carrying the outdoors where it is difficult to care about handling, the moisture-proof effect can be maintained.

When the bullet 5 is fired, the embolus 12 and the embolus 13 closing both ends of the grip cap 9 are removed, the launch tube 10 is taken out of the grip cap 9, and the launch tube 10 is gripped as shown in FIG. It is attached and fixed to the 9 side of the shooting mechanism mechanism 11 installed.
Thereafter, the user attaches the embolus 12 again to the take-out tube 10 take-out side of the grip cap 9 to grip the grip cap 9, and pulls out the firing needle release plug 8, for example. Then, the firing pin 7 advances to the detonator 2 on the bottom surface of the launch tube 10 inside the housing of the firing mechanism 11 and strikes the detonator 2. The detonator 2 is ignited by this impact, and the postponing drug 3 is burned.
The postponement drug 3 burns over, for example, about 5 seconds after firing, and ignites the propellant 4. When the propellant 4 ignites, the cylinder hole internal pressure of the launch tube 10 rises, the launch tube plug 6 is removed from the tip of the launch tube 10, and the bullet 5 is fired.

The postponement drug 3 is for delaying the firing of the bullet 5 as described above, and, for example, the time for directing the tip of the firing tube 10 in the direction of firing the bullet 5 after the firing needle release plug 8 is operated. Is provided.
In other words, the delay time until the bullet 5 is fired can be set by the amount of the postponing drug 3 inserted into the tube hole of the launch tube 10, for example, a delay time of about 5 seconds as described above. An amount of the postponing drug 3 is generated in the launch tube 10 in such a manner as to cause

As described above, according to the present embodiment, since the launch tube 10 can be covered with the grip cap 9 except when the signal bullet (bullet 5) is fired, the launch tube embolus 6 that seals the tip of the launch tube 10 is used. At the same time, the moisture-proof effect inside the launch tube 10 can be enhanced, and the signal bullet firing device 1 can be stored for a long period of time by suppressing the deterioration of the medicine and the like.
Further, by covering the launch tube 10 with the grip cap 9, it is possible to prevent the launch tube embolus 6 from being damaged during carrying. In addition, by covering the launch tube 10 with the grip cap 9, it becomes possible to prevent the projecting portion and the like from being exposed to the outside of the signal bullet firing device 1, and the user or the like may be injured during carrying or carrying. It is possible to prevent the burden and to increase the safety in handling.
Further, by setting the signal bullet emitting device 1 in a state in which the firing tube 10 is inserted into the insertion hole portion of the grip cap 9, the size of the signal bullet emitting device 1 in the longitudinal direction can be suppressed, and the storage space is suppressed. can do.

Further, when firing a signal bullet (bullet 5), it is only necessary to fix the firing cylinder 10 to one end of the grip cap 9 or the side where the shooting mechanism unit 11 is installed, and it is necessary to set the signal bullet on a dedicated firing gun or the like. Therefore, a signal bullet can be fired by a simple preparation operation, and it is not necessary to carry the above-mentioned firing gun or the like.
Further, when firing the signal bullet, after operating the firing pin release plug 8, a delay time until the launch is provided by combustion of the postponement drug 3, so that the signal bullet firing device 1 is directed in a desired direction. And the signal bullet can be reliably launched to a target position such as the sky.
