Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a model gun, and more specifically, to a model gun, and more specifically, to a model gun, in which a bullet fired from the muzzle is seen flying away with a clear glow at night or in a dark place. This invention relates to a toy gun that fires luminescent bullets.

[Conventional technology]

Conventional toy guns of this type include so-called air guns, which use air pressure to fire synthetic resin bullets from the barrel, and ray guns, which fire a beam of light from the barrel at a target with a light-receiving element installed in a part of the gun. is widely known.

Air gun type play guns use colored synthetic resin bullets with flat tips or perfectly spherical outer shapes so as to pose no danger during use. In addition, the bullets of this air gun type toy gun are colored as vividly as possible so that the trajectory of the bullet after being fired from the gun barrel can be clearly seen.

[Problem that the invention seeks to solve]

Among the conventional toy guns, the air gun type has brightly colored bullets, but
It is not possible to confirm the trajectory of a fired ball in a dark place at night or during the day. Therefore, this type of air gun type toy gun is limited to use in a well-lit room during the day and at night. However, if you are forced to use it at night or in a dark place,
It is also conceivable to mix luminescent pigments (luminous pigments) as colorants when molding bullets from synthetic resin. However, as is well known, when external light energy is applied to these luminescent pigments, the pigment components become excited, and even after the light stimulation has stopped, they remain in a luminescent state for a predetermined period of time. It has the property of lasting. Therefore, even if synthetic resin bullets are mixed with such luminous pigments, if these bullets are to be used at night or in a dark place, they must be loaded into the gun barrel in advance. Since the material must be exposed to illumination light to give it phosphorescent properties, the problem is that it is time-consuming and uninteresting. In addition, as mentioned above, even if the luminous pigment inside the bullet accumulates light, once the irradiation with external light is stopped,
Since the luminous performance gradually decreases,
As time passes, the luminescence property almost disappears, and it no longer exhibits its value as a luminescent bullet. Furthermore, bullets mixed with luminous pigments cannot be given sufficient luminescence by simply being exposed to external light such as a fluorescent lamp before use, and their initial velocity is 70 m/min in the dark.
The problem is that the trajectory cannot be clearly seen when fired at a high speed of sec.

[Means for solving problems]

In view of the above-mentioned problems in the prior art, the present invention has been developed so that the bullet can be fired as a luminous body with sufficient brightness not only during the day but also at night and in dark places.
Therefore, it is an object of the present invention to provide a toy gun that allows the user to enjoy the sensation of firing extremely powerful bullets, day or night.

As a result of research, the present inventor found that the following two problems should be solved in order to obtain such a play gun. One of them is a synthetic resin bullet molded with luminescent pigment.
When each bullet is fired from within the gun barrel, the bullet is irradiated with powerful light in the visible and near ultraviolet range, giving the bullet an extremely high excitation level of phosphorescent energy.

Second, the irradiation of the bullet with the above-mentioned powerful light beam is performed synchronously within an extremely short period of time immediately after the bullet is given firing energy in the barrel but before it is fired from the muzzle. Therefore, the bullet should be given the highest luminous intensity during the short period of 1 to 2 seconds during which it is fired from the muzzle and flies through the air.

As a means for solving the above-mentioned problems, the present invention specifically includes a sensor that detects the passage of a bullet having an afterglow characteristic of a luminescent pigment, located in front of a bullet firing mechanism in a gun barrel; The present invention is characterized by the provision of a flash irradiation device for providing a sufficient amount of brightness of light to the passing bullet to exhibit its phosphorescent properties, based on the electrical signal detected by the sensor.

The sensor for detecting the passage of a bullet used in the structure of the present invention includes a light emitting element that emits light toward the inside of the gun barrel, and a reflector that reflects the light from the light emitting element to the bullet passing inside the barrel. It is preferable to use a photointerrupter comprising a light-receiving element that catches the light from the light-emitting element outside the gun barrel through the bullet as a reflector.

In addition, in this invention, the flash must be irradiated into the body for an extremely short period of time while the bullet is passing through the gun barrel before being fired from the muzzle.
Therefore, it is best to use a camera's strobe flash tube as the flash irradiation device. For example, a flat tube with a length of 35 mm,
It is placed closer to the muzzle than the bullet passage detection sensor in the gun barrel, and when the bullet is fired at an initial velocity of approximately 70 m/sec, the bullet passes within the area of the flash tube having a length of 35 mm. Since the time is about 1/2000 seconds, if this flash tube is irradiated with a flash time of about 1/5000 seconds, which is shorter than the bullet passage time, it is possible to reliably irradiate the flash light to the passing bullet. can.

[Effect]

In the toy gun according to the present invention, when a bullet containing a luminescent pigment is loaded into the barrel and preparation for firing is completed by operating the bullet firing mechanism consisting of an air pump, etc., the window of the barrel, which is partially transparent, is inserted into the gun barrel. The flash unit of the placed strobe flash tube is charged by the battery. When the trigger is pulled and the bullet is fired, a sensor placed inside the gun barrel detects the bullet's passage. This sensor acts as a tuning switch for supplying power to the strobe flash tube, so when a bullet crosses this sensor, the switch circuit of the flash unit is closed through this bullet, and the flash unit is then turned off from the flash unit. When energized, a powerful flash is emitted. Due to the extremely short distance between the sensor and the flash tube and the high speed of the bullet, the bullet is exposed to flash irradiation synchronously as it passes through the flash tube area, causing the contained phosphorescence to disappear. The pigment emits light when stimulated by strong light energy.

〔Example〕

Next, a preferred embodiment of the toy gun according to the present invention will be described based on the drawings. Fig. 1 is a cross-sectional view of the present invention applied to an air gun equipped with a general-purpose air pump type bullet firing mechanism 1. . Bullet firing mechanism 1

A lever 7 that protrudes from the side of the gun body 6 is provided on the outside of the piston 4, and by pulling this lever 7 toward the rear of the gun body 6, the piston 4 is moved to a predetermined position behind the cylinder 3. do. The piston 4 is locked at a predetermined position where a claw 8 protruding from the rear end engages a link 9 connected to the trigger 10. At that time, the bullet loading section 1 at the rear end of the barrel 2 in front of the cylinder 3
1, bullets 13 are fed into the magazine 12 one by one by a spring 14. This bullet 13 consists of a spherical body of 6 mm in diameter made of synthetic resin mixed with an appropriate amount of luminescent pigment. The luminescent pigment may be mixed into the resin material at a stage before the bullet is formed, or the luminescent pigment may be applied to the surface of a bullet that has been previously formed into a spherical shape. It may also be done by any other method. Note that the luminescent color tone is preferably blue-white, yellow, or yellow-orange in terms of visibility and discrimination.

Inside the gun body 6 is a bullet 1 that is fired and passes through the gun barrel 2.
3 has a built-in flash irradiation mechanism known as the camera's "strobe". This flash irradiation mechanism is
A flash tube including a dry cell battery 15 housed in the gun handle 14, a charging flash unit 16 placed at the bottom of the cylinder 3, and a reflector plate 17a attached to a part of the outside of the gun barrel 2. It consists of 17. As shown in FIG.
The part to which the flash tube 17 is attached is made of transparent synthetic resin 2a.

A sensor 18 for detecting the state in which the bullet 13 has been fired and passed through the barrel 2 is provided at a portion closer to the cylinder 3 than the flash tube 17 on the outside of the barrel transparent portion 2a.
As shown in FIG. 4, this sensor 18 serves as a tuning switch for detecting the passing state of the bullet 13 and causing current to flow from the flash unit 16 to the flash tube 17.
As shown in FIG. 3, this sensor 18 includes, for example, a light emitting element 19a that emits an electrical signal from the flash unit 16 as a light beam into the inside of the gun barrel 2 through the transparent part 2a of the gun barrel, and It is preferable to use a photointerrupter that uses the passing bullet 13 as a reflector and catches the light beam emitted from the light emitting element 19a by the light receiving element 19b and returns it to the flash unit 16.

On the other hand, two switches 20 and 21 are provided in the circuit between the flash unit 16 and the dry battery 15. These switches 20 and 21 function to prevent unnecessary charging of the flash unit 16 from the dry battery 15. switch 20
is turned on when the piston 4 in the bullet firing mechanism is locked in a predetermined position, and the trigger 10 is turned on.
By pulling the link 9, the link 9 comes off from the claw 8 of the piston 4, and when the piston 4 is ejected into the cylinder 3, it becomes OFF.

As shown in FIG. 2, a safety device 23 having a safety lever 22 is provided on the outside of the gun body 6, and another switch 21 is connected to the safety device 23.
Three points 23a, 23b, 23c in
Of these, the flash conduction point 23c serves as one contact, and the safety lever 22 serves as the other contact. Therefore, when the lever 22 is rotated to the position of the flash conduction point 23c, the switch 21 is turned on. This safety device 2
Another point 23a at 3 is a lock point for preventing firing, and when the lever 22 is rotated to this lock point 23a, the switch 2
1 is turned off, and even if the trigger 10 is pulled, the piston 4 as a bullet firing mechanism does not operate. Also, another point 23b is the switch 21.
The piston 4 is ejected when the trigger 10 is pulled, although it is not turned on. Therefore, this point 2
3b is used when the bullet is not used as a luminescent bullet. In addition, near the flash conduction point 23c in this safety device 23, there is a pilot which indicates that the energizing circuit to the flash unit 16 is conductive when the lever 22 is rotated and the switch 21 is turned on. Preferably, a lamp 24 is provided.

In order to fire the luminous bullet 13, first pull the piston lever 7 outside the gun body backwards to release the piston 4.
Set to the firing lock position. This compresses the spring 5 and turns on the switch 20 of the charging circuit in the flash unit 16.

When the trigger 10 is pulled in this state, the piston 4 is unlocked, the piston 4 is press-fitted into the cylinder 3, and the air inside the cylinder 3 causes the bullet loading section to
A luminescent bullet 13 located at 1 is fired into the barrel 2. When the bullet 13 passes over the sensor 18, the bullet 1

It is irradiated with a powerful strobe flash and becomes luminous,
Fired from the muzzle as a luminescent bullet.

FIG. 5 shows another embodiment of the sensor mechanism for causing the flash tube 17 to emit light. This embodiment includes a switch mechanism consisting of two contact pieces 25a and 25b that come into contact with each other via the bullet 13 passing before the flash tube 17 in the gun barrel 2. In this structure, at least one of the contact pieces 25a is connected to the bullet 13.
The contact piece 25 protrudes into the barrel 2 in a direction that does not obstruct the passage of the bullet 13.
By pushing up a and making contact with another contact piece 25b embedded in the thick part of the gun barrel 2, the discharge circuit of the flash unit 16 is turned on and the flash tube emits light. When the bullet 13 passes through this position, the movable contact piece 25a separates from the fixed contact piece 25b, turning off the discharge circuit.

〔effect〕

Generally, bullets for toy guns are small, about 6 mm in diameter, so even if these bullets contain luminous pigments, they are sufficient to visually confirm that they are flying at high speed while glowing. In order to provide good phosphorescence performance, it is necessary to irradiate the product with light such as indoor fluorescent light for at least 10 seconds. Moreover, the luminescence time of the bullet after being given such a long irradiation time is only a short time of about 3 to 5 seconds, and within that time it can be seen as a luminescent bullet from a distance of about 5 to 10 meters. This is for the first 1 to 2 seconds at most.

In the present invention, when using a phosphorescent bullet as described above, a powerful flash with a sufficient amount of instantaneous light, such as a camera strobe, is applied to the bullet in the barrel just before it is fired from the muzzle. Since the bullet is irradiated with light, sufficient luminescence can be imparted to the bullet in a short period of time. In this case, the time it takes for a bullet to fly after being fired from the muzzle is about 1 to 2 seconds, so
Even if the bullet has a luminescent time of 3 to 5 seconds,
The brightest state during the first 1 to 2 seconds can be matched with the flight time of the bullet, resulting in extremely realistic firing of the luminous bullet.

In addition, since the firing of the luminescent bullet and the flash irradiation by the flash tube occur almost simultaneously, the flash of the flash tube can be seen from the muzzle at the moment the luminous bullet is fired from the muzzle, and it is similar to firing due to an explosion of gunpowder. It can give a sense of realism.
