Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stopping device for capturing a projecting bullet in shooting training and a shooting range of a firearm equipped with the stopping device, and more particularly, to a stopping device for capturing a projecting bullet by a granular member and the stopping device. Regarding firearm shooting range.

  Conventionally, as shown in FIG. 23, the shooting range includes a shooting position where the shooting shooter 1 is located, a target 2 arranged facing the shooting position, a breakwater 6 arranged in front of the target 2 (shooting side), A steel plate inclined backstop 4 disposed behind the target and a bullet collecting groove 5 disposed below the steel plate inclined backstop 4 are configured. In the case of applied shooting training, the shooting position may not always be determined.

  24 is a cross-sectional view taken along the line CC of FIG. In this example, the target 2 is movable in a direction orthogonal to the flight direction of the bullet, and the bullet dam 6 prevents the bullet from damaging the moving mechanism of the target 2. When the shooter attached to the shooting shoots an actual bullet with a handgun or a rifle toward the target, the fired bullet 8 flies in the target direction. Bullets that do not hit the target directly hit the steel plate inclined backstop 4 and are crushed, and those hitting the target pass through the target and hit the steel plate inclined backstop 4 to be crushed. The crushed bullets change their movement direction downward along the steel plate inclined backstop 4 together with the crushing and collect in the bullet collecting grooves 5.

However, the conventional steel plate inclined backstop has the following problems.
1) Bullet debris may become a bullet and scatter to the shooter side.
2) Lead powder is generated by bullet crushing on the steel plate surface, and the environment of the shooting range is contaminated.
3) At the time of collecting the bullet fragments collected in the bullet collecting groove 5, the worker may ingest lead powder.

  The technology disclosed in Patent Document 1 shown in FIG. 25 is a stopping device proposed to solve these problems. In this technology, a backstop in which the granular member 14 is deposited behind the target 2, that is, a bullet stopping device is provided, and the bullet is decelerated by entering the granular member 14, and the bullet is captured inside the granular member 14. To do.

  Further, in the technique of Patent Document 2 shown in FIGS. 26 to 27, the granular member 14 is filled in the space formed by the elastic film material 13 and the casing 19, the stopping device frame 16 and the support member 18 behind the target 2. A backstop, that is, a bullet stopping device is provided, and a bullet is caused to enter the granular member 14 to decelerate the bullet and capture the bullet inside the granular member 14.

  On the other hand, in a backstop using a granular member, if you continue to shoot using a granular member with a bullet in it, there is a possibility that a bullet captured in the granular member will collide with a bullet that will be fired later Will increase. When the bullets collide with each other, lead dust is generated due to the crushing of the bullet, and the advantage that the lead dust captured by the granular member is small is reduced. For this reason, periodic separation and removal of bullets in granular members is a necessary condition for backstops using granular members, and the separation and removal of bullets in granular members is the operational efficiency of the shooting range. It becomes a big factor to decide.

JP-B-5-20680 (page 3, Fig. 1) JP 2002-318097 A (3rd page, FIG. 1)

  The technique of the said patent document 1 accumulates the granular member 14 in the back of a target, and shoots a bullet into this granular member, thereby avoiding the crushing of the bullet and separately collecting the bullets from the granular member. However, in this technique, the granular member 14 is dropped from above and deposited, the captured bullets are moved downward together with the granular member 14, the bullets and the granular member 14 are separated by a sorting device, and only the granular member 14 is placed on the upper side again. From. In the technique disclosed in Patent Document 1, a bullet fired toward the target 2 is stopped and captured at a penetration reaching distance t in the granular member 14 due to friction with the granular member 14. At this time, the penetration reaching distance t shows a substantially constant value in the material and shape of the granular member 14, the shape of the bullet to be shot, and the kinetic energy, so that the bullets gather in the bullet concentration area 22 behind the target 2. In this technique, since it is necessary to move and separate the granular members 14 other than the bullet concentration region 22 occupying the majority of the granular members 14, the efficiency of bullet separation is very poor. In addition, a large-scale device for transferring, sorting, and refilling the granular member 14 from the top is required.

  Similarly, in the technique of Patent Document 2, the bullets fired gather in the bullet concentration area 22 behind the target 2 as shown in FIG. When the operation of extracting the bullets and the granular member 14 from the lower part of the bullet concentration area 22 is performed, the granular member 14 of the bullet concentration area 22 is in the process of being extracted. As shown in FIG. 28B, the volume of the granular member 14 that is mixed with the member 14 and from which the bullets are to be separated becomes large. Since the bullet and the granular member 14 are separated with respect to the increased volume of the granular member 14, the separation efficiency is lowered.

  On the other hand, as shown in FIG. 29 (a), even in a backstop having a shape in which granular members such as sand and stone-free earth are inclined and deposited below the angle of repose as the granular members, Gathered in the bullet concentration area 22 behind. As shown in FIG. 29 (b), when the work of scraping the bullet and the granular member 14 from the bullet concentration region 22 of the backstop is performed, the granular member 14 holds the angle of repose from above in the bullet concentration region 22. The phenomenon that collapses occurs. For this reason, the granular member 14 in the bullet concentration region 22 and the granular member 14 in the region where the ratio of bullets is small are mixed, and the volume of the granular member 14 from the bullet concentration region 22 scraped out of the backstop is as shown in FIG. As shown in (b) of 29, the volume of the granular member 14 in the original bullet concentration region 22 becomes larger, and as a result, the separation efficiency for separating the bullet and the granular member 14 is lowered. This scraping work method is based on other methods such as a scoop and is not shown.

  The elastic-viscosity film 13 is for maintaining the thickness of the granular member 14 in the direction of bullet movement, avoiding the scattering of the granular member 14 due to the impact of the bullet landing. The same problem occurs in the backstop having a slope shape in which the member 14 is deposited.

  Furthermore, when the target installed in front of the stopping device adopts a target that moves in the left-right direction, or the shooting where the shooter fires toward the entire circumference without specifying the position of the target that is the shooting target in particular There was no idea about the shooting range and the stopping device for training.

  The subject of this invention is improving the efficiency of the operation | work which sorts and collects the bullet caught by the granular member from the granular member.

  The first means of the present invention for achieving the above-mentioned object is to place a bullet, which is arranged behind the target of the actual shooting of the firearm and fired in the direction of the target, into the deposited granular member. It is a bullet stopping device to capture, and is provided with a partition member that separates the granular member in the bullet concentration region from the granular member in the region other than the bullet concentration region.

  The partition member advances to the region where the granular member is deposited and separates the granular member in the bullet concentration region from the granular member in the region other than the bullet concentration region, and a direction away from the target from the region where the granular member is deposited It is desirable to be configured to be movable so as to be able to take any position of the position that does not hinder the mixing of the granular member in the bullet concentration area and the granular member in the area other than the bullet concentration area.

  The granular member may be made of an elastic material, sand particles, soil particles, or a material in which two or more of them are mixed.

  The second means of the present invention for achieving the above object is to place a bullet, which is arranged behind the target of the actual shooting of the firearm and fired in the direction of the target, into the deposited granular member. A shooting range including a stopping device for capturing, wherein the stopping device described in the first means is provided as the stopping device.

  It is preferable that the bullet stopping device is disposed so as to surround a place where a bullet is fired.

  In the shooting range where the target position is not determined or the shooting range where the target is moved to the left and right with respect to the shooter, the landing position and direction of the bullet cannot be specified. However, since shooting training with firearms fires at targets in the size range of humans assuming enemies or criminals, the bullet is centered around 1.4m above the floor, which is roughly equivalent to the height of the human torso center. Almost 90% or more land in the range of about 0.4 m above and below the height (1 m to 1.8 m above the floor). This is also common in the case of training to shoot a target moving left and right with respect to the shooter. The area where the bullets are concentrated is called the bullet concentration area.

  When shooting a target that does not move in the left-right direction from a fixed shooting position, the bullet concentration area is limited not only in the up-down direction but also in the left-right direction.

  By providing a partition member that separates the granular member in the bullet concentration region from the granular member in the region other than the bullet concentration region in the region where the granular member is deposited, it is possible to take out the granular member mixed with bullets only from the bullet concentration region It becomes. For this reason, the amount of separation / collection work is reduced as compared with the prior art, work efficiency is improved, and maintenance and operability can be greatly improved.

  In addition, the partition member that separates the granular member in the bullet concentration region from the granular member in the region other than the bullet concentration region is withdrawn from the region where the granular member is deposited to the side opposite to the target during the shooting, By moving forward to the region where the granular member is deposited only when performing the operation of taking out the mixed granular member, the granular member in the bullet concentrated region and the granular member in the region other than the bullet concentrated region are separated and separated. The member can be prevented from being damaged by shooting.

  According to the present invention, it becomes possible to take out the granular member mixed with bullets only from the bullet concentration area, so that the efficiency of the work of separating and collecting the bullet captured by the granular member from the granular member as compared with the prior art. It will be possible to greatly improve maintenance and operability.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. In FIG. 1, the top view of the shooting range which concerns on this Embodiment is shown. In the shooting field shown in FIG. 1, the stopping device 12 is arranged so as to surround a place where the shooter 1 shoots toward the target 2. In this shooting range, not only is it possible to carry out shooting training in which the shooter 1 shoots at the target 2 as a shooting target in an arbitrary direction, but bullets that have been removed from the target 2 are also installed in all directions. Since it is captured by the device 12, the safety of training can be ensured. The present invention can be applied not only to the case where the shooting field plan figure is rectangular like the illustrated shooting field but also to circular and polygonal shooting fields. As for the entrance / exit of the trainee (shooter 1) to the shooting range, as shown in FIG. 1, a part where the shooting bullet does not reach directly is opened, and a part of the stopping device 12 is moved to constitute the entrance / exit. You may do it. Further, the target 2 as a shooting target may be a fixed target, a target that moves in the shooting field in the front-rear and / or left-right direction, and a target that performs an action that appears from a hidden state.

  FIG. 2 is a side cross-sectional view showing a cross section taken along line AA in FIG. The illustrated stopping device 12 is disposed in contact with the wall and floor of the shooting range building 23 and includes a stopping device frame 16 having an inclined surface that increases as the distance from the shooter 1 increases, and the inclined surface of the stopping device frame 16. A bullet-proof structural member 17 which is fixed to the upper part of the granular member 14 deposited on the upper part of the bullet-stop device frame 16 and forms a V-shaped space between the wall of the shooting range building 23, and the accumulated granular member The granular film 14 and the bullet concentration area of the bullet concentration area 22 are arranged above the elastic film material 13 covering the surface 14 and the bullet concentration area 22 so as to extend in a direction orthogonal to the inclined surface and orthogonal to the paper surface. And a partition member 24 separating the granular member 14 above 22.

  The bullet concentration area 22 is behind the target 2 as seen from the shooter 1 and has a height from the floor surface of the shooting range building 23 in a range where the center height of the target 2 is about ± 0.4 m. If the center height of the target 2 is 1.4 m from the floor surface, the bullet concentration area 22 may be considered to be in the range of 1.0 m to 1.8 m from the floor surface.

  Further, the bulletproof structural member 17 installed on the upper part of the bullet stopping device has the granular member 14 necessary for capturing the bullet even if the particle size of the granular member 14 is gradually reduced due to friction with the bullet due to shooting. It also serves as a temporary storage / replenishment mechanism for the granular member 14 to be replenished in order to maintain the thickness t.

  When the shooter 1 shoots at the target 2, the bullet that has penetrated the target 2 and the bullet that has not hit the target 2 and has come off around the target 2 land on the shooter side of the stopping device 12 installed on the back. To do. The bullet that has landed has its kinetic energy attenuated by friction with the internal granular member 14, and is captured in the stopping device.

  Although not shown in the figure, the target 2 may be driven by a target driving device 7 as shown in FIG. The bank 6 may be installed between the archer 1 and the stopping device 12.

  In FIG. 2, the granular member 14 of the bullet stopping device 12 is divided into upper and lower divided areas by a partition member 24 that separates the bullet concentration area 22 where the bullets on the back of the target 2 are concentrated and the granular member 14 on the upper part thereof. ing.

  When the bullet captured inside the granular member 13 is taken out from the bullet stopping device 12 for the purpose of separation / collection operation, as shown in FIG. Since it is blocked by the partition member 24, it becomes possible to take out only the granular member 14 having a large amount of bullets mixed in the bullet concentration region 22, and the workability can be greatly improved as compared with the prior art. As shown in FIG. 4, the bullets captured in the granular member 14 shown on the right side of FIG. 3 are separated and taken out only by the bullets, and only the granular member 14 is returned to the inclined surface of the bullet stopping device 12. The function of the stopping device 12 is restored.

  As shown in FIG. 4, even when the taken granular member 14 is returned to the inclined surface after the separation of the bullets, it is only necessary to return the granular member 14 taken out from the bullet concentration region 22, thereby reducing the amount of work.

  Further, since the partition member 24 may be hit, it is necessary to manufacture the material with a material that does not cause bullet crushing or bounce due to the hit. In the present embodiment, the material of the partition member 24 includes any one or more of elastic rubber, plastic, reinforcing fiber cloth or mesh material, and composite materials thereof. Fiber-like and / or granular chips of these elastic materials were molded with a binder and laminated on a plate-like or block-like shape having a porosity of 20 to 40%. With such a configuration, it is possible to prevent the bullet from being crushed and the occurrence of a bullet by the bullet, and to maintain the damage life due to the shooting of the partition member 24 for a long time. It is also possible to use wood, plywood or the like for the material of the partition member 24, but the damage life due to the impact is inferior to that due to the elastic material.

  The method of scraping out the particulate material 14 and bullet contamination is based on other methods such as a scoop and is not shown. The elastic-viscous film 13 is intended to prevent the granular member 14 from scattering due to impacts caused by the impact of bullets, and to maintain the thickness of the granular member 14 in the direction of bullet movement. The partition member 24 also has the same effect even in the slanting device having the slope shape in which 14 is deposited.

FIG. 5 is a partially broken perspective view showing the structure of the bullet stopping device 12 of the present embodiment. As shown in FIG. 5, the granular member 14 is inclined and deposited on the inclined surface of the stopping device frame 16 to provide a partition member 24, and the granular member 14 side of the granular member 14 is prevented from scattering when entering the bullet. The surface is covered with an elastic film material 13. Further, the bulletproof structural member 17 installed at the upper part of the bullet stopping device has a granular member thickness necessary for capturing the bullet even if the particle size of the granular member 14 is gradually reduced due to friction with the bullet due to shooting. It also serves as a temporary storage / replenishment mechanism for the granular member 14 that is replenished so that the above can be maintained. Unlike the examples shown in FIGS. 2 to 4, the cross-sectional shape is rectangular.
(Second Embodiment)
A second embodiment of the present invention will be described with reference to FIGS. FIG. 6 shows a state in which the bullet stopping device according to the present embodiment is shot, and a state in which the granular member 14 including the captured bullet is taken out from the bullet concentration area of the bullet stopping device 12 for the purpose of sorting and collecting work, FIG. 7 is a cross-sectional view showing a state where the granular member 14 that has finished the separation and collection of bullets is returned to the bullet stopping device 12. 8 is a cross-sectional view illustrating the detailed structure and operation of the partition member 24 of FIG. 6, and FIGS. 9 and 10 are cross-sectional views taken along the line B1-B1 in FIG. (B) B2-B2 line arrow directional cross section is shown.

  The present embodiment differs from the first embodiment in that the partition member 24 of the first embodiment is fixed to the bullet-stop device frame 16, whereas the present embodiment is different from the first embodiment. The partition member 24 is configured such that it can be advanced and retracted with respect to the inclined surface of the stopping device frame 16. Since other components are the same as those in the first embodiment, illustration and description thereof are omitted.

  As shown in FIG. 6 and FIG. 8A, the partition member 24 includes a section structure (pin slide support section) 26 fixed to the inclined surface of the stopping device frame 16 and a section structure (pin slide support section). 26, and a segment structure (pin) 25 that advances and retreats along the segment structure (pin slide support portion) 26. The division structure (pin) 25 can be fixed so as not to slide down at a position where it has advanced to the upper side of the inclined surface of the bullet stopping device frame 16.

  At the time of shooting, the granular member 22 accumulates the segment structure (pin) 25 as shown in FIG. 8 (a) so that the segment mechanism 24 is not damaged by the bullets entering the stopping device 12 and the bullet is not crushed. It is operated as a state in which it is drawn from the area where it is retracted to the rear surface of the inclined surface of the stopping device frame 16.

  When sorting and collecting the bullets captured inside the granular member 13, first, as shown in FIG. 8B, the dividing structure (pin) 25 is advanced into the granular member 14 and the dividing structure (pin) 25. Is fixed at a position where the tip of the elastic film material 13 reaches the elastic film material 13, and the bullet concentration region 22 and other regions, in this case, the region above the bullet concentration region 22 are divided by a dividing structure (pin) 25. Even if the granular member 14 in the bullet concentration area 22 is taken out, as shown in FIG. 8 (c), the area above the bullet concentration area 22 is relatively less contaminated by the section structure (pin) 25. Therefore, the granular member 14 mixed with bullets can be taken out only from the bullet concentration region 22.

  Further, after the granular member 14 in the bullet concentration area 22 is taken out, as shown in FIG. 8D, the section structure (pin) 25 is pulled into the rear surface of the slanted surface of the bullet stopping device frame 16, thereby blocking the dam. The granular member 14 that has been flown into the bullet concentration region 22 is filled with the inclined surface of the bullet stopping device 12 and the function of the bullet stopping device 12 is restored. Furthermore, as shown in FIG. 7, the granular member 13 from which the bullets are separated is returned to the upper part of the bullet stopping device 12, and the function of compensating for the volume reduction of the granular member 14 due to the collision between the granular member 14 and the bullet is restored.

  The partition member 24 includes a partition structure (pin) 25 and a partition structure (pin slide support portion) 26. As shown in FIGS. 9 and 10, the partition structure (pin) 25 includes a plurality of sections. The structure (pin) 25 is formed in a comb shape in which the structures (pins) 25 are arranged and connected at regular intervals, and the resistance when being drawn into the granular member 14 is reduced. The interval between the segmented structures (pins) 25 is preferably set to the average particle diameter of the granular member 14. Moreover, when using the sand grain and soil grain material with the small average particle diameter of the granular member 14, the division member 24 is a division structure (partition plate) between the division structures (pins) 25 as shown in FIG. 27 may be connected to each other, and this structure may be advanced and retracted.

  As shown in FIGS. 13 and 14, the partition member 24 further connects at least the distal ends of the partition structure (pins) 25 with a connection member 20, and attaches the partition structure (film material) 28 to the connection member 20. A structure in which the section structure (film material) 28 is wound around a take-up shaft 26 a provided in the section structure (pin slide portion) 26 in accordance with the insertion and removal of the section structure (pin) 25 may be adopted. This segmented structure (film material) 28 may be a film material having a strength that can withstand the internal pressure due to the mass of the granular member 14, and may be an elastic material, cloth, wire mesh, or the like. A thin metal plate may be used if it can be wound.

  9 to 14, the granular member 14 between the elastic membrane material 13 and the stopping device frame 16 is not shown.

  16 and 17 show examples of driving means for moving the partition member 24 shown in FIGS. 9 and 10 forward and backward with respect to the granular member 14. However, in FIGS. 16 and 17, the granular member 14 between the elastic membrane material 13 and the bullet-stop device frame 16 is not shown. The illustrated driving means includes a rope 30 attached to the tip of the section structure (pin) 25 and a float 29 fixed to the end of the rope 30. The float 29 is selected to have a specific weight smaller than the bulk specific gravity of the granular member 14 so that it does not sink into the granular member, and since it may be hit during shooting, the material is an elastic material.

  In a state where the shooting shown in FIG. 16 is performed, that is, in a state where the section structure (pin) 25 is retracted to the back surface (lower surface) of the bullet-stop device frame 16, the float 29 is located immediately behind the elastic film material 13, It floats on the surface of the granular member 14. When the section structure (pin) 25 is advanced into the granular member 14 to divide the bullet concentration area 22 and the area above it, the elastic film material 13 is removed, and the section structure (pin) 25 is pulled by holding the float 29. The pin 25 is pulled out into the granular member, and the state shown in FIG. When the sorting structure (pin) 25 is returned to the stored state shown in FIG. 16, the tip of the sorting structure (pin) 25 may be pressed with a bar or plate not shown.

  FIGS. 18 and 19 show other examples of driving means for moving the partition member 24 shown in FIGS. 9 and 10 forward and backward with respect to the granular member 14. However, also in FIGS. 18 and 19, the granular member 14 between the elastic membrane material 13 and the stopping device frame 16 is not shown. The illustrated driving means includes a connecting member 32 fixed to the surface of the segment structure (pin) 25 configured in a comb shape on the side opposite to the elastic film member 13, and a propulsion mechanism 31 having a driving end fixed to the connecting member 32. And. The other end (support end) of the propulsion mechanism 31 is fixed to a portion of the stopping device frame 16 not shown. By moving the propulsion mechanism 31 in and out, the partition structure (pin) 25 is advanced into the granular member 14 as shown in FIG.

Further, the propulsion mechanism 31 draws out the partition structure (pin) 25 into the granular member 14 such as an air / hydraulic cylinder, a jack with a screw structure, a winch structure using a pulley, a system using a solenoid and a spring, etc. Any mechanism may be used as long as the mechanism can return to the stored state shown in FIG.
(Third embodiment)
A third embodiment of the present invention will be described with reference to FIG. FIG. 15 shows a cross section of the bullet stopping device according to the present embodiment on a vertical plane parallel to the bullet flight direction. The illustrated stopping device is not provided with an inclined surface on which the granular member 14 is deposited unlike the stopping device in the first and second embodiments, and the granular member 14 is used in the shooting range building 23. It is filled between the bullet-stop device frame 16 arranged along the wall of this and the elastic membrane material 13 arranged with a gap between the bullet-stop device frame 16. The weight of the granular member 14 is supported by the support member 21 disposed at the bottom. Further, an openable / closable discharge port (not shown) is provided at the lower part of the elastic membrane material 13. Furthermore, the partition member 24u and the partition member 24d are installed at two positions in the height direction on the rear surface of the bullet stopping device, that is, at positions above and below the bullet concentration area.

(A) of FIG. 15 shows the state at the time of shooting, and the partition member 24u and the partition member 24d are retracted from the granular member 14 so as not to be hit on the rear surface of the bullet stopping device. The fired bullets gather in the bullet concentration area 22 behind the target. Hereinafter, with reference to FIG. 15B to FIG. 15H, a procedure for separating and collecting bullets from the granular member 14 in the bullet concentration area 22 and returning only the granular member 14 from the upper part of the bullet stopping device to the bullet stopping device. Will be explained.
A: The partition member 24u and the partition member 24d are drawn into the granular member 14, and the granular member 14 in the bullet concentration region 22 is separated from the granular member 14 in other regions ((b) in FIG. 15).
B: The granular member 14 in the region where the bullets are not concentrated below the partition member 24d is scraped by opening a discharge port (not shown) at the lower part of the stopping device (FIG. 15C).
C: The granular member 14 is discharged from the bullet stopping device ((d) in FIG. 15).
D: The partition member 24d is pulled out rearward of the bullet stopping device, and the granular member 14 in the bullet concentration area 22 is scraped to the lower portion of the bullet stopping device ((e) of FIG. 15).
E: The granular member 14 in the bullet concentration area 22 is discharged from the bullet stopping device, and is deposited separately from the granular member 14 discharged in step C ((f) in FIG. 15).
F: The discharge port (not shown) of the stopping device is closed, and the partition member 24u is pulled out to the rear of the stopping device. Thereby, the granular member 14 in the region where the bullets are not concentrated on the upper part of the bullet stopping device falls and fills the lower part of the bullet stopping device ((g) of FIG. 15).
G: Bullets are separated and collected from the granular member 14 in the bullet concentration area 22 discharged outside the stopping device, and only the granular member 14 is returned to the upper portion of the stopping device to restore the function of the stopping device (FIG. 15). (H)).

The structure of the partition member 24u and the partition member 24d in the third embodiment is the same structure as the partition member 24 described in the first and second embodiments.
(Fourth embodiment)
A fourth embodiment of the present invention will be described with reference to FIGS. 20 to 22 are projection views of the inclined surface on which the granular member 14 of the stopping device 12 is deposited as shown in FIG. 2 as seen from a direction perpendicular to the inclined surface. 20 to 22, the elastic film material 13 and the granular member 14 installed on the shooter side surface of the granular member 14 are not shown.

  As described above, the bullet concentration region 22 is a region behind the target in the range of the size of a human assuming an enemy or a criminal, and the center height of the target is the height of the center of the human torso, that is, approximately Since it is 1.4 m above the floor, the bullet concentration area 22 is in the range of about 0.4 m above and below the height (about 1 m to 1.8 m above the floor) centering on the floor 1.4 m, and the width in the horizontal direction is also 0. The area is about 8 m. Since FIG. 20 is a view of the inclined surface on which the granular member 14 is deposited as viewed from a direction perpendicular to the inclined surface, the bullet concentration area 22 is a long area in the vertical direction.

  When shooting a target whose position is fixed, the target is usually arranged at an arrangement interval (P) of 1.2 m or more. Therefore, as shown in FIG. 20, the partition member surrounds the periphery of the bullet concentration area 22. By arranging 24, the bullet concentration area 22 and the other areas can be divided.

  In the case of the stopping device of the type shown in FIG. 2 in which the granular member is deposited on the inclined surface, the granular member is taken out from the inclined surface side. In this case, since the granular member on the slope below the bullet concentration area 22 in FIG. 20 is unlikely to be mixed into the granular member in the bullet concentration area 22 due to the collapse of the slope, the partition member 24d may be omitted.

  Also, in the shooting range where training is performed to shoot the target moving forward, backward, left and right with respect to the shooter, the center height of the target is the height of the center of the human torso, that is, approximately 1.4 m above the floor. The bullet concentration area 22 of the bullet device is a belt-like area extending laterally within a range of about 0.4 m in height (about 1 m to 1.8 m above and below) about 1.4 m above the floor. In this case, as shown in FIG. 21, the partition members 24 are arranged above and below the bullet concentration area 22. Furthermore, by arranging the partition members 24 so as to divide the bullet concentration area 22 in the horizontal direction, it becomes possible to perform the work sequentially in the horizontal direction. Moreover, the partition member 24d may be omitted as described in the embodiment of FIG.

  Further, even in a shooting range where the target position or target moving direction cannot be specified, the bullet concentration area 22 is about 0.4 m above and below the height of the center of the human torso, that is, about 1.4 m above the floor. Since it tends to be (1 m to 1.8 m above the floor), as shown in FIG. 22, the granular member is taken out only from the region where the bullets are concentrated by dividing the bullet stopping device into a lattice shape by the partition member 24. Can do.

  Judgment of where the bullet concentration area is can be easily identified by making it an area that is severely damaged by bullet penetration of an elastic film material installed on the surface of the granular member (not shown). By repairing the elastic film material at the same time when the granular member is taken out, it is possible to easily determine the bullet concentration area until the next operation. In addition, the arrangement of the division structure 24 is to divide the range of about 0.4 m above and below the height (about 1 m to 1.8 m on the floor: H1) about 1.4 m (H0) above the floor at the center of the human torso. Is preferred.
