Abstract

A sound generation device (10) mounted on a gun device (1, 2) used in an optical target shooting competition detects an impact generated by a trigger unit (20) and generates a sound (S) in the audible range. When an impact is generated from the trigger unit (20), a visible light ray (X) is emitted from a light ray emission unit (30) and a sound (S) is also outputted from the sound generation device (10). When the visible light ray (X) is not incident on a target device and a landing point is not displayed on a display device (50), it can be determined that the shot was off-target.

Description

Sound generator and optical target shooting system

The present invention relates to a sound generator mounted on a gun device used in an optical target shooting competition and an optical target shooting system.

In target shooting in sports competitions, athletes aim at the target and compete for points at the position where the bullet actually fired with the rifle or pistol hits. In recent years, electronic targets have become the mainstream, in which targets are digitized, and the position where a bullet passes is detected to calculate a score. However, in Japan, possession of rifles and pistols is severely restricted due to regulations under the Firearms and Swords Possession Control Law (so-called Firearms and Swords Law).

Therefore, it is composed of a gun device (rifle type or pistol type) that emits light, and a target device and display device that detect the emitted light with a receiver and output the position of the detected light by converting it into a point. Beam rifle and beam pistol competitions have been developed. Since it uses a gun device that does not fire bullets, it is not regulated by the Firearms and Swords Law, and adults and children can enjoy target shooting purely as a sports competition. In a device developed for beam rifle competition or beam pistol competition, when the emitted light is received (detected) by the target device, a pseudo-fire sound of a gun is output from the display device.

Patent Document 1 discloses a toy gun that emits a flash provided at the muzzle when the trigger is pulled and reflects and resonates the sound of spark discharge to generate a pseudo-fire sound.

Further, a ray gun provided with a sounding device is disclosed in Patent Document 2. In order to simulate the vibration and sound of shooting and improve the user's feeling of shooting, this ray gun emits strobe light when the hammer is activated by the trigger operation and is supplied from the air cylinder. The gas is configured to generate vibrations and noise.

Further, it is disclosed in Patent Document 3 that when the trigger of a laser beam gun is triggered, a circular beam of a bundle of rays is emitted and a gunshot is sounded at the same time.

Jitsukosho 43-No. 674 (JPY1968000674) JPA 49-106199 (JPA1974106199) Special Fairness 03-052000 (JPB1991052000)

By the way, according to the configuration of the toy gun described in Patent Document 1, since the pseudo-firing sound is generated when the distance between the contacts is close and the electric discharge is performed, the synchronization between the light emission and the sound is unstable. Further, according to the ray gun described in Patent Document 2, a ray is emitted by a trigger operation, and the impact and sound of shooting are simulated by gas, but the gun is actually shot. It makes the user feel the feeling. Further, Patent Document 3 discloses that "a gunshot is sounded", but does not disclose a specific configuration or the like, and the subject of the invention is improvement of an electronic target device. As in Patent Document 2, it is not out of the scope of speculation that the purpose is to realize that the user has shot.

Although there are devices such as those in Patent Documents 1-3, the beam rifle for competitive shooting and the beam pistol itself are not equipped with a mechanism for generating a pseudo-firing sound.

In a targeted shooting competition that uses a bullet-launching gun, if the fired bullet does not enter the target, the athlete declares that there is an "off-target bullet hole" and the shooting score is calculated at zero. There must be. Even beam rifles and beam pistols, which are one of the target shooting competitions, should be treated in the same way when they are emitted outside the target.

However, in the case of beam rifles and beam pistols used in optical target shooting competitions, if the light emitted from the gun during the competition is not detected by the target device (that is, it deviates from the target), a simulated firing sound is produced. Does not occur. As a result, no one, including the referee, the players around, and the spectators, may be unaware that they have fired off the target. And the player who "fires out of the target" can behave as if nothing had happened.

In addition, in the case of a device that uses an infrared laser that is invisible light (invisible light), it is not possible to visually confirm that the light has been emitted. I can't dispel the doubt that is being incident. And since the invisible infrared laser is invisible, it is very dangerous if it gets into the eyes.

Therefore, the present invention provides a sound generator and an optical target shooting system capable of clearly determining "launching outside the target" during an optical target shooting competition.

The sound generator of the embodiment according to the present invention is a sound generator mounted on a gun device used in an optical target shooting competition. This gun device includes a main body held by the user, a trigger unit, and a ray emitting unit. The trigger unit is mounted on the main body and includes a trigger, a hammer and an urging means, and when the trigger is pulled, the hammer is activated by the urging means to generate an impact. The light ray emitting unit is mounted on the main body and emits visible light having directivity when the impact generated from the trigger unit and propagated through the main body is detected. Then, when the sound generator detects the impact generated from the trigger unit and propagated through the main body, the sound generator outputs at least the sound in the audible range to the outside of the main body.

At this time, it is preferable that the sound output from the sound generator is a pseudo-launching sound that resembles the firing sound of the actual package. Further, the sound generator is a sound generator in which the first propagation distance until the impact generated by the trigger unit propagates through the main body and is detected by the light emitting unit and the impact generated by the trigger unit propagates through the main body. It is also preferable to mount the sound on the main body at a position where the second propagation distance is shorter than the second propagation distance until it is detected in. The first propagation distance and the second propagation distance mean the paths for the impacts generated from the trigger unit to reach the impact detection sensors provided in the sound generator and the light ray emitting unit, respectively.

It is also preferable that the sound generator wirelessly outputs a unique signal indicating that visible light is emitted from the gun device equipped with the sound generator, in addition to the sound in the audible range.

The optical target shooting system of one embodiment according to the present invention is a gun device equipped with the above-mentioned sound generator and a target that detects visible light when it receives visible light emitted from a light emitting unit of the gun device. It includes a device and a display device that displays the position where visible light is detected by the target device.

At this time, a launch detection unit that detects the sound output from the sound generator and a landing determination that determines the presence or absence of a landing signal that is output when the target device detects visible light when the launch detection unit detects the sound. A unit and may be further provided.

Further, in the optical target shooting system of the embodiment according to the present invention, the sound generator separates the sound in the audible range from the specific signal indicating that the visible light is emitted from the gun device equipped with the sound generator. When outputting wirelessly, a gun device equipped with this sound generator, a target device that detects visible light when it receives visible light emitted from the light emitting unit of the gun device, and a target device that detects visible light. A display device that displays the position where the sound was generated, a launch detection unit that detects the eigen signal wirelessly output from the sound generator, and an output when the target device detects visible light when the eigen signal is detected by the launch detection unit. It is provided with a landing determination unit for determining the presence or absence of a landing signal.

According to the sound generator of the present invention, even if the visible light emitted from the gun device mounted on the gun device for optical target shooting does not enter the target, the sound accompanying the emission of the visible light is output. It becomes clear that there was a launch outside the target. Further, according to the optical target shooting system of the present invention, since the firing detection unit and the landing determination unit are provided, it is clarified that the shooting was performed outside the target based on the sound output from the sound generator. Can be determined.

The figure which shows the gun device which carries the sound generator of 1st Embodiment which concerns on this invention, and is used for an optical target shooting competition. The figure which shows the gun device which carries the sound generator of the 2nd Embodiment which concerns on this invention, and is used for an optical target shooting competition. The figure which shows the structure of the optical target shooting system of 3rd Embodiment which concerns on this invention.

(First Embodiment)
The sound generator 10 of the first embodiment according to the present invention will be described with reference to FIG. As shown in FIG. 1, the sound generator 10 is mounted on a laser beam rifle 1, which is an example of a gun device used in an optical target shooting competition. The laser beam rifle 1 includes at least a main body 100 held by the user, a trigger unit 20, and a light beam emitting unit 30.

The trigger unit 20 is incorporated in the main body 100, and includes a trigger 21, a hammer 22, an urging means 23, and a cocking lever 24. Details of the trigger unit 20 are shown partially enlarged in FIG. The trigger 21, the hammer 22, the urging means 23, and the cocking lever 24 are assembled to the case 25. The trigger 21 is connected to the shear 26. The hammer 22 is engaged and held by the shear 26 in a state of being urged by the urging means 23. When the trigger 21 is pulled, the shear 26 is removed from the hammer 22, and the hammer 22 is moved by the urging means 23. The moved hammer 22 collides with the striking portion 27 formed in the case 25 of the trigger unit 20 to generate an impact. By operating the cocking lever 24, the hammer 22 is returned to the position where it is held in engagement with the shear 26 again.

The trigger unit 20 shown in FIG. 1 shows an example of a structure for explaining the present invention, and if it has a function of generating a single impact by pulling the trigger 21. , Trigger units of other shapes and structures can also be applied to the present invention.

The light beam emitting unit 30 is attached to a tip portion 100a corresponding to the muzzle of the laser beam rifle 1. The light ray emitting unit 30 includes at least a power supply battery, an impact detection sensor, and a light emitting module. When the light emitting unit 30 detects the impact generated from the trigger unit 20 and propagated through the main body 100 by the shock detection sensor, the light emitting unit 30 has directivity visible light X from the light emitting module, for example, visible light laser (red, blue). , Green or other single wavelength is preferable) for a short time, for example, 0.01 seconds.

The light ray emitting unit 30 may have a delay module that delays a certain time from the detection of the impact to the emission of the visible light ray X. The delay time caused by the delay module is set to, for example, the time when a bullet actually fired from an air rifle, an air pistol, a cartridge rifle or a pistol reaches a target.

The sound generator 10 includes at least a power supply battery, an impact detection sensor, and a sound generation module. The sound generation module may be a memory that stores pre-recorded sound, a circuit that artificially synthesizes sound, or an amplifier that amplifies and outputs the propagated impact. .. When the impact detection sensor detects the impact generated from the trigger unit 20 and propagated through the main body 100, the sound generator 10 outputs at least the sound S in the audible range from the speaker to the outside of the main body 100.

The laser beam rifle 1 configured as described above generates an impact by the hammer 22 when the trigger 21 is pulled. The impact propagates through the main body 100 of the laser beam rifle 1 and is detected by the impact detection sensor of the sound generator 10 and the impact detection sensor of the light ray emitting unit 30, respectively. As a result, the sound generator 10 outputs the sound S in the audible range, and the light ray emitting unit 30 emits the visible light X having directivity. That is, in the optical target shooting competition, the laser beam rifle 1 outputs a sound S and emits visible light X in response to the impact generated by the hammer 22 of the trigger unit 20 instead of firing a bullet. Since the sound S is output by the sound generator 10, it can be visually confirmed that the visible light X has been emitted.

As described above, in the case of the laser beam rifle 1 equipped with the sound generator 10 according to the present invention, when the visible light X emitted from the laser beam rifle 1 does not enter the target device in the optical target shooting competition, In other words, since one shot that should be treated as "fire out of the target" is notified to the surroundings by the sound S in the audible range, it is surely determined that there was a "fire out of the target". be able to.

Since the sound S is generated from the laser beam rifle 1, the determination of launching outside the target is made based on the sound S output from the gun device, similar to the air rifle and air pistol, and the competition rifle and pistol of the cartridge. become able to. Therefore, it is easy to replace the optical target shooting competition using a gun device equipped with a sound generator 10 such as the laser beam rifle 1 with an air rifle, an air pistol, and a target shooting competition using a cartridge or pistol. To do. And if it is an optical target shooting competition that does not fire bullets, it will not be necessary to have permission to possess a gun, and it will be possible to safely participate in the target shooting competition from childhood like other sports competitions.

Note that the sound S output from the sound generator 10 may be a pseudo-launching sound that resembles the firing sound of the actual package, or may be an artificial sound that is easy to hear. If the sound generator 10 has several types of sound data in advance, it is possible to select different sounds between adjacent shooters and make it easier to distinguish them.

In FIG. 1, the sound generator 10 is located between the trigger unit 20 and the light ray emitting unit 30, and is unevenly arranged on the trigger unit 20 side. That is, the first propagation distance D1 until the impact generated from the trigger unit 20 is propagated through the main body 100 and detected by the light ray emitting unit 30, and the impact generated from the trigger unit 20 is propagated through the main body 100 to generate sound. When compared with the second propagation distance D2 until it is detected by the device 10, the sound generator 10 is mounted at a position where the second propagation distance D2 is shorter. As shown in FIG. 1, the sound generator 10 is not limited to being arranged between the trigger unit 20 and the ray emitting unit 30. The sound generator 10 may be arranged on the side opposite to the light ray emitting unit 30 with respect to the trigger unit 20, that is, on the stock (stock) 100b side.

Due to the configuration as described above, the impact is first detected by the sound generator 10 and then by the ray emitting unit 30, although there is only a slight time difference. That is, it is possible to generate the sound S first before emitting the visible light X. This is the same operation as an actual air rifle, air pistol, or cartridge rifle or pistol, so it is possible to reproduce a state closer to actual shooting. By providing the sound generator 10 with a delay module for adjusting the timing of generating the sound S, it is possible to synchronize the timing at which the sound S is output with the timing at which the visible light X is emitted from the light ray emitting unit 30.

The impact detection sensor of the sound generator 10 and the impact detection sensor of the light ray emitting unit 30 may be one. By detecting the impact generated by the trigger unit 20 with one impact detection sensor, sound S and visible light X can be output without causing a time difference, and by providing a delay module, the impact caused by the trigger operation can be detected. It is also possible to output the sound S and the visible light X with an arbitrary time difference from the starting point.

The electric power of the sound generator 10 and the light emitting unit 30 may be supplied from individually provided batteries or may be supplied from one battery. Further, the battery may be a battery or may be charged by being connected to an external power source.

Further, the sound generator 10 further includes a wireless unit, and separately from the sound S in the audible range, wirelessly transmits a unique signal indicating that visible light X is emitted from the laser beam rifle 1 on which the sound generator 10 is mounted. You may output with. If a dedicated receiver is installed at the shooting range where the shooting competition is held and the unique signal output wirelessly is detected, it is possible to further determine which shooter uses the laser beam rifle 1 to emit visible light X. It will be easier. Then, if the sound S output from the sound generator 10 and the unique signal output wirelessly are linked with the target device, whether or not the emitted visible light X is incident on the target device and how many shots are emitted. It can be easily determined such as whether or not it is.

(Second Embodiment)
The sound generator 10 of the second embodiment according to the present invention will be described with reference to FIG.
As shown in FIG. 2, the sound generator 10 of the present embodiment is mounted on a laser beam pistol 2, which is a gun device used in an optical target shooting competition. Similar to the laser beam rifle 1 of the first embodiment, the laser beam pistol 2 has a sound generator 10, a trigger unit 20, and a light emitting unit 30 built in the main body 200.

Since the functions and structures of the sound generator 10, the trigger unit 20, and the light ray emitting unit 30 are the same as those described in the first embodiment, the description here will be omitted. As shown in FIG. 2, the sound generator 10 is not limited to being arranged between the trigger unit 20 and the ray emitting unit 30. The sound generator 10 may be built in the grip portion.

The electric power supplied to the sound generator 10 and the light emitting unit 30 may be supplied from individually built-in batteries or may be supplied to each from one battery. The battery may be a replaceable commercially available battery or a battery that can be recharged by connecting to an external power source.

The laser beam pistol 2 of the second embodiment has the same function as the laser beam rifle 1 of the first embodiment, and the same effect can be obtained by being used in an optical target shooting competition.

(Third Embodiment)
FIG. 3 shows the sound generator 10 of the third embodiment according to the present invention and the optical target shooting system 3 including the laser beam rifle 1 and the laser beam pistol 2 as a gun device equipped with the sound generator 10. It will be explained with reference to. Since the laser beam rifle 1 and the laser beam pistol 2 in the present embodiment are as described in detail in the first embodiment and the second embodiment, overlapping description relating to their respective functions and structures will be omitted.

The optical target shooting system 3 includes a laser beam rifle 1 or a laser beam pistol 2, a target device 40, and a display device 50. The target device 40 is installed at a distance and height according to the competition rules, detects the visible light X when the visible light X emitted from the light ray emitting unit 30 of each gun device is incident, and outputs a landing signal. To do. The display device 50 individually corresponds to the target device 40 and is installed near the shooter holding the gun device. The display device 50 has at least a display 51 that displays the position where the visible light X is detected by the target device 40.

A scoring unit for determining where the visible light X is incident on the target device 40, that is, at what point the target has landed may be provided on either the target device 40 or the display device 50. However, a part of the function may be shared and provided for each. For example, the target device 40 detects the visible light X and outputs a landing signal including the coordinate data of the center position thereof, and the display device 50 converts the landing signal including the coordinate data into a score and converts it into a display 51. Display in. The target device 40 and the display device 50 may be connected by wire or wirelessly.

The optical target shooting system 3 including at least the above configuration emits visible light X even if the visible light X emitted from the laser beam rifle 1 or the laser beam pistol 2 is not incident on the target device 40. Since the accompanying sound S is emitted from the sound generator 10 and the position where the visible light X is detected is not displayed on the display device 50, it can be clearly determined that there was a "fire out of the target".

In the third embodiment, the optical target shooting system 3 further includes a launch detection unit 60 and a landing determination unit 70. The firing detection unit 60 is installed corresponding to, for example, the display device 50, and has a sound sensor 61 that detects the sound S output from the sound generator 10. In order to prevent erroneous detection of the sound S emitted by another laser beam rifle 1 or laser beam pistol 2 used adjacently, the profile of the sound S of the laser beam rifle 1 or laser beam pistol 2 to be used is preliminarily emitted and detected. It is preferable that the sound generator 10 has a function of registering in 60 or setting the sound S of the laser beam rifle 1 and the laser beam pistol 2 used adjacent to each other to the sound S of different profiles.

When the launch detection unit 60 detects the sound S, the landing determination unit 70 determines the presence or absence of the landing signal in which the visible light X is detected by the target device 40. When it is determined that there is a landing signal, it means that the visible light X corresponding to the sound S output from the laser beam rifle 1 or the laser beam pistol 2 is incident on the target device 40. When it was determined that there was no landing signal, the visible light X corresponding to the sound S output from the laser beam rifle 1 and the laser beam pistol 2 was not incident on the target device 40 (that is, "launch outside the target" was emitted. It means that there was).

If it is determined that there has been a "launch outside the target", the landing determination unit 70 may indicate on the display device 50 that there has been a launch outside the target, or simply score "0.0". It may be displayed as a point. In addition, when there is a "fire out of the target" during the main shooting in the target shooting competition, a display or an operation button for making a declaration in accordance with the competition rules is displayed on the display 51 of the display device 50. It may be displayed.

Further, according to the optical target shooting system 3 of the present embodiment, when another person who should shoot another target accidentally hits the target device 40, the firing detection unit 60 does not detect the sound S. Based on this, it can be easily determined that the shot was erroneously fired.

Further, in a target shooting tournament in which a plurality of optical target shooting systems 3 are used at the same time, a tournament management system for integrated management of each optical target shooting system 3 is provided, and the target device 40 of each optical target shooting system 3 is provided. By determining the output landing signal and the sound S output from the sound generator 10 of each laser beam rifle 1 or each laser beam pistol 2 detected by the shooting detection unit 60 in association with each other, "target". It is possible to easily determine not only "outside launch" but also "supervisory misfire".

Further, the sound generator 10 mounted on the laser beam rifle 1 or the laser beam pistol 2 wirelessly outputs a unique signal set individually for each gun device in addition to the sound S in the audible range, and the tournament management system , This unique signal may be received via (or directly) the launch detector 60. The tournament management system can grasp that the tournament is running smoothly by comparing the acquired unique signal with the landing signal of the target device 40 of the firing position where the gun device that is the source of the signal is used. It is possible to accurately determine "fire outside the target" and "misfire during supervision".

Although the laser beam rifle 1 and the laser beam pistol 2 are shown in FIG. 3 as if they use the same target device 40, both of them have the same function for convenience of explaining the optical target shooting system 3. It just shows that it does. In practice, the gun device is selected according to the sport, and the target size of the target device 40 is also selected according to the gun device to be used.

Further, the target device 40, the display device 50, the launch detection unit 60, and the landing determination unit 70 may be connected to each other by wire or wirelessly. The launch detection unit 60 and the landing determination unit 70 may be partially incorporated in one or both of the target device 40 and the display device 50.

Further, an indicator light indicating that visible light X is emitted may be provided on the outer surface of the laser beam rifle 1 or the laser beam pistol 2 as a gun device used in the optical target shooting system 3. The indicator light may be used in combination with the sound generator 10, or may be provided in place of the sound generator 10. It is preferable that the indicator light is kept lit when there is a "fire out of the target".

Further, the laser beam rifle 1 and the laser beam pistol 2 may be equipped with a counter that counts the number of times the visible light X is emitted after the main shooting is started in the target shooting competition. The optical target shooting system 3 outputs a warning when the number of shots by the counter and the number of shots of visible light X on the target device 40 and the display device 50 do not match. If the number of shots of the counter is large, it means that there was a "fire outside the target", and if the number of impacts on the target device 40 or the display device 50 is large, it means that there was a "misfire between supervision" that was misfired by others. It means that there was. The function of this counter may be provided as an independent separate unit, or may be incorporated into another unit mounted on the laser beam rifle 1 or the laser beam pistol 2 as a gun device. The counter may include a display module that displays the number of shots on the outer surface of the gun device.
