必要奥行きＤは、下式で示される。However, the conventional steel-made inclined backstop described above has the following problems. 1) Bullet fragments may become trillion bullets and fly toward the shooter. 2) Lead powder is generated by bullet crushing on the steel plate surface, and the environment of the shooting range is polluted. 3) There is a risk that the worker may ingest lead powder during the work of collecting bullet fragments collected in the bullet collecting groove 5. The technique disclosed in Japanese Patent Publication No. Hei 5-20680 shown in FIG. 12 is a bullet stopping device proposed to solve these problems. In this technique, a granular member 14 is deposited behind a target, and a bullet is shot into the granular member, thereby avoiding crushing of the bullet and separating and recovering the bullet from the granular member. However, in this technique, since the granular member 14 is dropped from above and deposited, the surface of the formed granular member on the firing side is a slope having a repose angle θ of the granular member. Therefore, assuming that the required effective thickness t of the granular member for capturing the bullet in the shooting direction and the installation height of the bullet stopping device are H, the required installation depth D of the bullet stopping device is expressed by the following equation.
【０００６】Ｄ≧ｔ＋Ｈ／tanθ 一般的な射撃場の場合、Ｈ＝４ｍ，粒状部材の安息角θ

【０００７】これに対して、堆積された粒状部材の射座

なり、停弾装置の設置必要奥行きを大幅に低減できる。On the other hand, if the angle of inclination of the deposited granular member on the firing point side can be made nearly vertical, D ≒ t, and the required depth of the ballistic stopping device can be greatly reduced.

FIG. 14 shows FIG. 1 as the number of bullets fired increases.
It is sectional drawing which shows the state in which the bullet stop device of No. 3 changes.

の発生などの原因となる。When the number of bullets shot is small, FIG.
(A), as the number of bullets shot increases, the state changes to (c) in FIG. 14 through (b) in FIG. This is due to the fact that a bullet penetrates through the elastic film material to damage the film material, and the weight of the granular member filled at the bottom acts as an internal pressure, causing swelling. Due to this swelling, the internal granular members are entirely lowered, and as shown in FIG. 14 (c), the bullet stopping performance of the upper part of the bullet stopping device is reduced, and crushing of bullets and trillion bullets occur. Bullet crushing causes the generation of fine lead powder and trillion bullets.

In addition, in a bullet stopping device that is widened to the left and right, it is difficult to uniformly fill or unload the granular member when filling the granular member from the upper portion or extracting the granular member from the lower portion.

る。SUMMARY OF THE INVENTION A first aspect of the present invention to achieve the above-mentioned object is to arrange a bullet which is disposed behind a target of a live fire of a firearm, and is fired by a shooter toward the target. In a bullet stopping device that captures with a granular member, at least the surface on the shooter side is made of an elastic film material, and the granular member is filled in a casing to which a frame is fixed. And an outlet for the granular member is provided, and the casing on the side opposite to the elastic film material is fixed by a plurality of support members extending in a vertical direction.

均一にできる。[0014] Since a plurality of vertically extending supporting members for fixing and supporting the casing on the side opposite to the elastic membrane material are provided,
Elongation of the elastic film material in the vertical direction is suppressed, and swelling of the elastic film material in the vertical direction can be prevented. Also, in the left-right direction, since the granular member is divided by the supporting member, the granular member can be formed to have a uniform thickness without being biased in the left-right direction, and since the granular member is partitioned by the supporting member, the granular member is filled in a predetermined place. , Can be extracted uniformly.
【００１５】なお、この支持部材が撃ち込まれる弾丸で

望ましい。[0015] In order to prevent the support member from being damaged by the shot bullet, it is preferable that the installation position of the support member be outside the area where the target is projected onto the elastic film material.
【００１６】さらに、前記標的が複数個横に並んで配置
されている場合、前記複数の支持部材は、同様の理由か
ら、前記複数の標的の中間に対応する位置に分散配置す
るのが望ましい。Further, when a plurality of the targets are arranged side by side, it is desirable that the plurality of support members are dispersedly arranged at a position corresponding to the middle of the plurality of targets for the same reason.
【００１７】射撃訓練での標的は、通常、射手から見

的範囲を通過する頻度は、標的の中心に近いほど高い。The target in shooting training is usually a concentric circle or a culprit, viewed from the shooter, and is 0.75 m long and 0. 5 m wide.
The concentric circle or the image of the criminal is printed in a 75 m square area. Also, the evaluation of the shooting result,
The higher the distance to the center of the concentric circle, the higher the height, so that about 90% or more of the fired bullets cover the target range (for example, the vertical 0.75 mm).
m, a 0.75 m square area), and the frequency of bullets passing through the target area increases as the distance to the center of the target increases.

出を低減できる。Therefore, a bullet stopping device for catching the fired bullet with the granular material filled therein is installed behind the target, and an elastic film material for holding the front surface of the filled granular material is provided. By disposing a support member for fixing and supporting the elastic film material at a position outside the region corresponding to the target range of the material, damage to the support member and the fixed support portion of the elastic film material by bullets can be reduced. That is, swelling of the elastic film material toward the shooter can be reduced.

い。As described above, it is necessary to set the support member at a position outside the area corresponding to the target area of the elastic film material, and to set an interval of 1 to 2 times the horizontal dimension of the target area. Alternatively, it is desirable to set it at the center position of the target arrangement interval.

強度を有するものであればよい。In the case of a shooting range in which the target is moved while moving in the lateral direction, the main reach of the bullet is a band-shaped area horizontally moved in the vertical direction of the target with the movement of the target. In this case, the support members may be installed at upper and lower positions outside the band-like region. It is necessary to select a material for the support member that is unlikely to cause bullet crushing, and may be the same material as the elastic film material constituting the firing-side surface of the bullet stopping device, or a cloth material, a cloth laminate material, or a mesh material. Any material may be used as long as it can transmit the internal pressure of the granular member, which is applied to the elastic film material, inside the bullet stopping device to the structural material constituting the bullet stopping device.

すことで、容易に再使用することができる。The bullets caught by the bomb stop device are discharged from the lower portion of the bomb stop device together with the granular members, and are separately collected.
At this time, since the bullets are recovered in a substantially original shape, it is possible to prevent the worker from ingesting lead powder during the recovery operation. The separated granular member can be easily reused by returning it to the inside of the device from the upper part of the bomb stop device.
