【発明の属する技術分野】
本発明は、屋内で実弾射撃訓練を行う射撃訓練装置に関する。
【0002】
【従来の技術】
公知例の特開平1−193600号公報、特開平1−248000号公報に記載されているように、屋内で実弾射撃訓練を行う射撃訓練装置には暗い屋内でも標的が見やすいことからスクリーン上に投影装置を用いて標的映像を投影する形式が多く用いられている。
【0003】
【発明が解決しようとする課題】
特開平1−193600号公報に記載されている例では、射撃手から見てスクリーン(光透過型)の背面から標的映像を投影している。投影機を被弾から保護するためにスクリーンの材質として実弾が貫通せず、高い弾着圧に耐え、しかも弾着位置を正確に検出できるものを選択する必要があり、スクリーンが高価なものとなっている。
一方、特開平1−24800号公報に記載されている例では、投影機をスクリーンの斜め下方向に配置して被弾から保護しているためスクリーンの材質として実弾の貫通を阻止するものを用いる必要が無いので安価になっている。
しかし、上記公知例を含む従来の屋***撃訓練装置では、実弾がスクリーン背面の停弾堤に進入する際に発生する粉塵により投影機に悪影響があり、投影機の寿命を短縮するのみならず、レンズに堆積する粉塵によりスクリーン上の標的映像が不鮮明になる。また、屋***撃訓練装置では照準が大きく外れた場合、天井や側壁に実弾が当って反射弾となり着弾検出器等の監的部構造物の被弾による被害も発生している。
本発明の目的は、射撃訓練装置の機器に対する粉塵の悪影響を排除することにある。また、機器の被弾を防止し寿命を延長することにある。
【0004】

【0005】
【発明の実施の形態】
以下、本発明の実施の形態を図により説明する。
図1は本発明の実施の形態の射撃訓練装置構成を示す説明図である。
本図に示すように本実施の形態の射撃訓練装置は、射座1から射手が発射した実弾8がスクリーン3に的中した時に放射される衝撃波を非接触にて検出し、検出データにより射座1の着弾位置表示器10に着弾位置を表示する着弾位置検出器2と、この着弾位置検出器2を射手が発射した実弾8による直接被弾、射撃訓練装置の内壁からの反射弾による被弾被害から保護する着弾位置検出器停弾堤4と、スクリーン3へ斜め下方より標的映像を投影する液晶プロジェクタ等の投影機12と、この投影機12を収納する投影機筐体5と、隣接する射撃レーンからの衝撃波が着弾位置検出器2へ侵入しないように遮蔽する遮蔽幕7と、着弾位置検出器2及び投影機12を射手が発射した実弾8による直接の被弾から保護する総合停弾堤9とから主に構成している。
スクリーン3は投影機12から投影する標的映像を鮮明に表示可能な色彩で構成され、射座1に対して垂直に配置している。スクリーン3の材質としては標的映像を鮮明に表示可能であること、実弾8が貫通する時の摩擦熱により着火して燃焼が拡大しない難燃性であり、有る程度の耐久性を併せ持てば良い。
遮蔽幕7はスクリーン3と同材質であり難燃性を有する。また、射座1とスクリーン3を結ぶ線と平行にかつ、射撃レーン間の中心に設置されるため実弾8の弾痕は直線的になり、実質的には隣接する射撃レーンからの衝撃波が着弾位置検出器2へ侵入する欠損領域が生じ難い。この遮蔽幕7の射座1方向の長さLは以下のように求める。
【0006】
図2は本発明の実施の形態の遮蔽幕の寸法決定根拠を示す説明図である。
まず、射手が発射した実弾8は空気中では円錐形の衝撃波を伴う。
本図において実弾8の速度をv、雰囲気温度における音の速度をVとすれば、衝撃波の開き立体角αは次式で求められる。
α=アークsin(V/v)…………………(1)
ここで開き立体角αは、実弾8の通過線CDと、着弾位置検出器2のA点を含む面と、各着弾位置検出器2A〜H含む面間の角度でもあるが、図形的にはこれらの立体角が着弾位置検出器2A〜H含む面に比べて0°になる個所、即ち実弾8が各着弾位置検出器2A〜Hの存在する面上を通過した時が遮蔽幕7の長さLは最大となるため平面的に考えると遮蔽幕7の長さLは次式で求められる。
L=ltanα…………………………………(2)
但し、lは遮蔽幕位置(射撃レーン間中心)から隣射撃レーンの最も遠い着弾位置検出器2Aまでの距離
図1おいて遮蔽幕7の設置はワイヤ、金属棒等でレールを構成し、遮蔽幕7側に取り付けたフックにより天井から吊り下げて行う。
【0007】
図3は本発明の実施の形態の被弾防止を説明する説明図である。
そして、射座1から目視できる範囲の金属構造物には全て被弾防止の対策を施す。具体的には金属構造物に被弾しても射手側に跳ね返らないように実弾8が反射するように考慮された角度の被弾防止板を取り付ける。図3によると最終的に被弾防止板の角度θは金属構造物に突入してくる実弾8の最大入射角度γmaxに依存することになる。射撃訓練装置の内壁からの反射角度は最悪でも内壁への入射角度よりも小さな反射角度は生じないとして、あらゆる射撃訓練装置条件のパラメータにより金属構造物へ向かっての最大入射角度γmaxを算出する。そのγmaxにより被弾防止板の角度θは次式のように限定される。
θ<90−γmax……………………………(3)
投影装置は基本的に標的映像を投影する本体、本体を収納する筐体、筐体内を冷却する冷却装置から構成する。
【0008】
図4は本発明の実施の形態の投影機の構成を示す説明図である。
本実施の形態では標的映像を投影する本体が投影機12、投影機12を収納する筐体が投影機筐体5である。ここで冷却装置について詳細に説明する。
吸気取入口13は射撃訓練装置外の粉塵の少ない空気を取り入れるもので、吸気ファン14は取り入れた空気を投影機12へ送りこみ冷却する。整流板15は吸気ファン14から吐出された空気が投影機筐体5内の構造により偏流が生じないように整流する。整流された空気が投影機吸気口16から投影機12内へスムーズに流れ込む。投影機12内を冷却して温度が昇した空気は投影機12に連結した投影機排気口17、投影機排気口17内に配置したフィルタ18を経由して投影機筐体5外に排出される。
標的映像は投影機12のレンズ19、投影機筐体5の投影窓20を介してスクリーン3に投影されるが、射撃訓練の際に停弾堤11を構成する無石土から大量の粉塵が発生し、静電気を帯びた無石土の粉塵がガラス若しくはアクリル製の投影窓20に堆積してスクリーン3に投影される標的映像を不鮮明にする。そこで本実施の形態では投影窓20の上部に投影機筐体5の投影機筐体排気口21を配置し、投影機筐体排気口21にフィルタ18を取付けて粉塵が少ない空気を投影窓20に吹き付けて無石土の粉塵を一掃している。
【0009】
図5は本発明の実施の形態の投影機冷却系の構成を示す斜視図である。
本図は吸気取入口13へ粉塵の少ない空気を取り入れる構成を示し、射撃訓練装置外に防滴、防塵、防虫に配慮した外気取入口25を配置し、外気取入口25から外気母管26、外気枝管27を介して各投影機筐体5の吸気取入口13に連結する。
投影機、着弾位置検出器2を屋***撃訓練装置特有の反射弾、直撃弾による被弾を回避するため、図1に示すように射座1側に着弾位置検出器停弾堤4と総合停弾堤9を設置する。
【0010】
図6は本発明の実施の形態の投影機筐体と第1の被弾防止装置の関係を示す斜視図である。
また、投影装置への反射弾による被弾を回避するため、本図に示すような被弾防止カバー6で投影機筐体5を被覆する。投影機12の投影方向以外の着弾位置検出器停弾堤4方向からの反射弾より保護する材質は実弾8の衝突衝撃に耐えうる硬度、被弾確率、実弾8の材質を考慮した上で適宜選択する。
【0011】
【発明の効果】
本発明によれば、標的映像投影手段を収納する防塵構造の筐体を設け、筐体へ粉塵の少ない外気を導入して標的映像投影手段を冷却し、粉塵を除いた空気を標的映像投影手段の投影窓に噴出させて堆積する粉塵をパージすることにより、射撃訓練装置の機器に対する粉塵の悪影響を排除する効果が得られる。
【0012】
そして、標的映像投影手段の筐体を第1の被弾防止手段により被覆し、遮蔽幕の支持機構、着弾位置検出手段に対し射撃方向の被弾を防止する第2の被弾防止手段を設けることにより、機器の被弾を防止し寿命を延長する効果が得られる。

[0005]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an explanatory view showing the structure of a shooting training apparatus according to an embodiment of the present invention.
As shown in the figure, the shooting training apparatus of the present embodiment detects a shock wave emitted when the real bullet 8 fired by the shooter from the shooting position 1 hits the screen 3 in a non-contact manner, and uses the detection data to detect the shooting position 1. The landing position detector 2 that displays the landing position on the landing position indicator 10 of the head, and the impact position detector 2 is protected from direct damage by the actual bullet 8 fired by the shooter and damage from damage by the reflected bullet from the inner wall of the shooting training apparatus. The landing position detector stop dam 4, the projector 12 such as a liquid crystal projector that projects the target image obliquely downward onto the screen 3, the projector housing 5 that houses the projector 12, and the adjacent shooting lane A shielding curtain 7 that shields the shock wave from entering the landing position detector 2, and a general breakwater 9 that protects the landing position detector 2 and the projector 12 from being directly hit by the actual bullet 8 fired by the shooter. main It is configured.
The screen 3 is configured with colors that can clearly display the target image projected from the projector 12, and is arranged perpendicular to the shooting position 1. The material of the screen 3 is that the target image can be clearly displayed, the flame is ignited by the frictional heat when the actual bullet 8 penetrates, and the combustion does not expand, and it should have a certain level of durability. .
The shielding curtain 7 is made of the same material as the screen 3 and has flame resistance. In addition, since it is installed in parallel with the line connecting the shooting position 1 and the screen 3 and at the center between the shooting lanes, the bullet hole of the actual bullet 8 is linear, and the shock wave from the adjacent shooting lane is substantially detected by the impact wave. It is difficult for a defect area to enter the vessel 2 to occur. The length L of the shielding curtain 7 in the direction of the seat 1 is obtained as follows.
[0006]
FIG. 2 is an explanatory diagram showing the basis for determining the dimensions of the shielding curtain according to the embodiment of the present invention.
First, the actual bullet 8 fired by the shooter is accompanied by a conical shock wave in the air.
In this figure, if the velocity of the actual bullet 8 is v and the velocity of the sound at the ambient temperature is V, the open solid angle α of the shock wave can be obtained by the following equation.
α = Arc sin (V / v) …………… (1)
Here, the open solid angle α is also an angle between the pass line CD of the actual bullet 8, the plane including the point A of the landing position detector 2, and the plane including each of the landing position detectors 2A to H. The portion where the solid angle is 0 ° compared to the surface including the landing position detectors 2A to 2H, that is, the time when the actual bullet 8 passes over the surface where the landing position detectors 2A to 2H exist is the length of the shielding curtain 7. Since the length L is the maximum, the length L of the shielding curtain 7 can be obtained by the following equation when considered in a plane.
L = ltanα ………………………………… (2)
However, l is the distance from the shielding screen position (center between the shooting lanes) to the farthest landing position detector 2A in the adjacent shooting lane. In FIG. 1, the shielding screen 7 is configured by forming a rail with wires, metal bars, etc. It is suspended from the ceiling by a hook attached to the curtain 7 side.
[0007]
FIG. 3 is an explanatory view for explaining bullet prevention according to the embodiment of the present invention.
All metal structures that are visible from the mount 1 are protected against bullets. Specifically, a bullet prevention plate having an angle that allows the actual bullet 8 to be reflected so as not to bounce back to the shooter side even if it hits a metal structure is attached. According to FIG. 3, the angle θ of the bullet-proof plate finally depends on the maximum incident angle γmax of the actual bullet 8 that enters the metal structure. Assuming that the reflection angle from the inner wall of the shooting training apparatus is worst and no reflection angle smaller than the incident angle to the inner wall is generated, the maximum incident angle γmax toward the metal structure is calculated according to the parameters of all shooting training apparatus conditions. Due to the γmax, the angle θ of the bulletproof plate is limited as shown in the following equation.
θ <90−γmax ……………………… (3)
The projection apparatus basically includes a main body that projects a target image, a housing that houses the main body, and a cooling device that cools the inside of the housing.
[0008]
FIG. 4 is an explanatory diagram showing the configuration of the projector according to the embodiment of the present invention.
In the present embodiment, the main body that projects the target image is the projector 12, and the housing that houses the projector 12 is the projector housing 5. Here, the cooling device will be described in detail.
The intake air intake 13 takes in air with less dust outside the shooting training apparatus, and the intake fan 14 sends the taken air into the projector 12 for cooling. The rectifying plate 15 rectifies the air discharged from the intake fan 14 so that no drift occurs due to the structure inside the projector housing 5. The rectified air flows smoothly from the projector inlet 16 into the projector 12. The air whose temperature has been raised by cooling the inside of the projector 12 is discharged out of the projector housing 5 via a projector exhaust port 17 connected to the projector 12 and a filter 18 disposed in the projector exhaust port 17. The
The target image is projected onto the screen 3 through the lens 19 of the projector 12 and the projection window 20 of the projector housing 5, but a large amount of dust is generated from the stoneless earth that constitutes the dam 11 during the shooting training. The target image projected on the screen 3 is blurred because the generated and stone-free earthless dust accumulates on the projection window 20 made of glass or acrylic. Therefore, in the present embodiment, the projector housing exhaust port 21 of the projector housing 5 is disposed above the projection window 20, and a filter 18 is attached to the projector housing exhaust port 21 so that air with less dust is projected into the projection window 20. The dust is wiped off by spraying on the stone.
[0009]
FIG. 5 is a perspective view showing the configuration of the projector cooling system according to the embodiment of the present invention.
This figure shows a configuration in which air with a small amount of dust is taken into the intake air inlet 13, an outside air intake 25 that is drip-proof, dust-proof, and insect-proof is arranged outside the shooting training device, and the outside air mother pipe 26 from the outside air inlet 25, The projector is connected to the intake port 13 of each projector housing 5 via the outside air branch pipe 27.
As shown in FIG. 1, the landing position detector pier 4 and the general pier are located on the side of the shooter 1 in order to avoid the impact of the projector and the landing position detector 2 due to the reflection bullets and direct hit bullets specific to the indoor shooting training apparatus. 9 is installed.
[0010]
FIG. 6 is a perspective view showing the relationship between the projector housing and the first bulletproof device according to the embodiment of the present invention.
Further, in order to avoid the impact of the reflected bullet on the projection device, the projector housing 5 is covered with a bullet prevention cover 6 as shown in the figure. Landing position detector other than the projection direction of the projector 12 The material to be protected from the reflected bullet from the direction of the breakwater 4 is appropriately selected in consideration of the hardness that can withstand the impact impact of the actual bullet 8, the probability of being hit, and the material of the actual bullet 8. To do.
[0011]
【The invention's effect】
According to the present invention, a dust-proof structure housing the target image projection means is provided, the target image projection means is cooled by introducing outside air with less dust into the housing, and the air excluding dust is removed from the target image projection means. By purging the dust that is ejected onto the projection window and depositing, an effect of eliminating the adverse effect of the dust on the equipment of the shooting training apparatus can be obtained.
[0012]
Then, by covering the casing of the target image projection means with the first bullet prevention means, and providing the second mechanism for preventing the bullet in the shooting direction against the support mechanism of the shielding curtain and the landing position detection means, The effect of preventing the impact of the equipment and extending the life can be obtained.
