Description

[Detailed Description of the Invention] This invention relates to a device for practicing shooting using a real pistol without firing live bullets.

Police officers who are allowed to use firearms are required to practice shooting, but because there are only a few shooting ranges, it takes a lot of time to go to the range, which interferes with their work.

Furthermore, even in countries overseas where there are few restrictions on the use of firearms, it is difficult to practice shooting freely, as firing live ammunition indiscriminately would cause trouble to people in the neighborhood.

The applicant first replaces the rotating magazine of the real pistol with a mock magazine in order to have the applicant practice target shooting safely and without causing inconvenience to others, and to familiarize the applicant with using the pistol that he or she owns. At the same time, a device was developed in which a projection optical tube was inserted into the gun cavity, and the light emitted from a simulated magazine by trigger operation was emitted as a thin beam of light through the optical tube.

In that case, in order to use an optical barrel with the same outer diameter for pistols of various calibers, the outer diameter must be made considerably thinner, and the optical barrel must be made of metal in terms of force and mechanical strength. .

However, inserting a metal product into a gun cavity tends to be discouraged because it involves the risk of damaging the inner surface of the gun cavity.

In addition, the optical barrel to be inserted into the gun cavity must not have a large frictional resistance during insertion and removal, and the optical axis of the optical barrel must match the central axis of the gun cavity so that the light beam accurately matches the trajectory. It is desired that a highly accurate optical system be easily assembled, and that it can be applied to pistols of various calibers by simply replacing a minimum number of parts.

This idea involves interposing a synthetic resin connecting tube with a pinhole in the center and an outer diameter approximately equal to the pistol caliber in the middle of a thin metal optical tube, thereby reducing the frictional resistance when inserting it into and removing it from the gun cavity. , does not damage the barrel, the light beam accurately matches the trajectory, is easy to assemble, provides high optical accuracy, and can be adapted to pistols of different calibers simply by using connecting tubes with different outer diameters. The purpose of this invention is to realize a pistol shooting range with an optical barrel that can be used, and this will be explained below by means of illustrated embodiments.

Figure 1 shows a real pistol equipped with a shooting practice device according to this invention, where 1 is the barrel, 2 is the frame, 3 is the gun grip,
4 is a hammer, 5 is a trigger, 6 is a simulated magazine installed after removing the rotating magazine, and 7 is an optical tube inserted into the gun cavity 8 toward the simulated magazine 6.

As shown in FIG. 2, the optical tube 7 is made of metal and has a thread 9 formed on the outer periphery of its tip, into which a head 10 is screwed.

The head 10 has a light emitting hole 11 at the bottom, and a projection lens 12 is held between the edge of the hole and the tip edge of the optical tube 7.

The inner diameter of the portion of the head 10 after the threaded connection with the optical tube 7 widens to form an annular space 13 between the head 10 and the optical tube 7, and a sliding tube 14 and a spring 15 are accommodated in this space. are doing.

The sliding tube 14 has a long hole 16 in a part thereof, and a pin 17 provided on the head 10 engages with the long hole 16, so that the sliding tube 14 moves into the space 1.
It prevents you from escaping from 3.

The sliding tube 14 has a conical surface 18 at its rear edge, and this conical surface 18
With the rear end of the optical barrel 7 connected to the dummy magazine 6, the optical barrel 7 is brought into close contact with the muzzle edge by the pressing force of the spring 15, and aligned with the central axis of the optical barrel 7.

The rear end of the optical barrel 7 extends into the simulated magazine 6, as shown in FIG. There is.

The optical barrel 7 is as shown in FIG.

It is separated into a front part 7a and a rear part 7b at a rearward position, and a connecting tube 21 is fitted into the separated part.

The connecting tube 21 has a diaphragm 23 having a pinhole 22 in the center.
inside, and the front and rear optical barrels 7 a and 7 b
The outer surface has an annular ridge 24 sandwiched between the ends thereof and in contact with the inner surface of the barrel, and these are integrally made of synthetic resin.

The position of the pinhole 22 substantially coincides with the focal point of the projection lens 12.

As shown in FIGS. 3 and 4, the simulated magazine 6 has a rotating shaft insertion hole 25 at the center and a toroidal space 26 around it.

A hole 27 having a shape equal to the cross section of the optical barrel 7 is provided in the front wall 6a facing the gun cavity 8, and a locking lever 28 is pivoted by a pin 29 close to the hole 27.

One end of the locking lever is pressed toward the hole 27 by the spring 30, and the other end projects onto the outer surface of the simulated magazine 6.

This locking lever 28 is connected to a notch 20 recessed in the optical barrel 7.
It is engaged with the notch 20 and detached from the notch 20 by operating from the outside.

In the space 26 inside the simulated magazine 6, there are a condenser lens 31, a xenon discharge tube 32, a reflector 33, a light emitting circuit 34, and a power source battery 3.
5 and a light emitting switch 36 are housed therein.

The xenon discharge tube 32 faces the rear end surface of the optical barrel 7 with the lens 31 in between, and the light emitting switch 36 faces a hole 37 provided at the collision position of the hammer 4 in the rear wall 6b of the simulated magazine.

In the pistol equipped with the above-mentioned practice device, when the trigger 5 is pulled, the hammer 4 hits the light-emitting switch 36 to close it, and the discharge tube 32 emits a flash.

This flash of light is focused onto the pinhole 22 by the condenser lens 31 and projected onto the target by the projection lens 12 as a small light spot.

Therefore, the practitioner can practice shooting with a real pistol that he or she owns, and does not cause any harm or trouble to the neighbors.

As mentioned above, there are various sizes of pistol calibers, but according to this invention, the connecting tube 21 whose outer diameter of the annular protuberance 24 is suitable for the caliber of the pistol can be selected, and it can be used for pistols of various calibers. can do.

Even though the optical barrel 7 itself is made of metal, it is the annular protuberance 24 of the synthetic resin connecting tube 21 that comes into contact with the inner surface of the gun cavity, so there is no risk of damaging the inner surface of the gun cavity.

Furthermore, when inserting and removing the gun into the gun cavity, the annular protuberance 24 only comes into close contact with the inner surface of the gun cavity, so the frictional resistance is small.Furthermore, as the annular protuberance 24 is positioned by the inner surface of the gun cavity, the pinhole 22 is It is located precisely on the central axis of the gun cavity, and during assembly, the distance between the projection lens 12 and the pinhole 22 is precisely regulated by the length of the front part 7a of the optical barrel, thereby projecting a narrow light beam that precisely matches the trajectory. can do.
