Description

  The present invention relates to a shooting training field for shooting real bullets with a firearm and a stopping device for capturing bullets.

  Conventionally, for example, as shown in FIG. 13, the shooting range is arranged in the shooting position where the shooting shooter 1 is located, the target 2 arranged facing the shooting position, and in front of the target 2 (shooting side). It is configured to include a bullet barrier 6, a steel plate inclined backstop 4 disposed behind the target, and a bullet collecting groove 5 disposed at a lower portion of the steel plate inclined backstop 4. In the case of applied shooting training, the shooting position may not always be determined.

  The target 2 shows a state seen from the shooter side, and is movable in a direction orthogonal to the flight direction of the bullet. The bullet pier 6 is provided to prevent the bullet from damaging the moving mechanism of the target 2.

  When the shooter attached to the shooter shoots a real bullet such as the handgun 3 toward the target, the fired bullet 8 flies toward the target. The bullets 8 that did not hit the target directly hit the steel plate inclined backstop 4 and were crushed, and the bullets 8 hit the target hit the steel plate inclined backstop 4 and crushed. The crushed bullet 8 moves downward along the steel plate inclined backstop 4 together with the crushing and collects in the bullet collecting groove 5.

  However, such a steel steel inclined backstop 4 has a possibility that the fragment of the crushed bullet becomes a bullet and is scattered to the shooter side, or lead powder is generated from the crushed bullet, leading to environmental pollution of the shooting range. In addition, when collecting the bullet fragments collected in the bullet collecting groove 5, the operator may ingest lead powder.

  Therefore, in order to solve such a problem, a bullet stopping device shown in FIG. 14 has been proposed. In this system, the elastic film material 13 that forms the shooter side surface, the casing 28, the frame 14 that forms the surface opposite to the shooter side, and the like are disposed behind the target 2, and the elastic film material 13 is attached to the frame 14. By filling the space composed of the support member 29 with the granular member, the bullet penetrating the elastic membrane material 13 is decelerated by the granular member and captured (see Patent Document 1).

Japanese Patent Laid-Open No. 2002-318097 (FIGS. 1 and 3)

  However, the stopping device used in the shooting range needs to be selected according to the power of the firearm 3. That is, in the bullet stopping device of Patent Document 1, it is necessary to set the thickness of the granular member in the direction in which the bullet 8 is landed and enters in accordance with the power of the bullet fired by the firearm 3. Therefore, when the firearm 3 having a relatively high power is used, there is a problem that the thickness of the granular member is increased, and the internal pressure is increased accordingly, and the elastic member 13 on the surface is easily swelled.

  In order to suppress the swelling of the elastic member 13, it is necessary to support the elastic film material 13 at a predetermined interval by increasing the number of support members 18 installed. However, if the number of support members 18 installed is increased, the support members 18 are likely to be hit and damaged, and it becomes difficult to maintain the stopping and catching performance for a long time. Further, even if the supporting members 18 are increased, the elastic film material 13 between the supporting members 18 swells with time due to the internal pressure of the granular member, and the surface of the bullet stopping device becomes undesirably undulated. Moreover, since the stopping device holds the horizontal excitation force at the time of an earthquake with the upper and lower frames 14 via the elastic membrane material 13, there is a problem that it is necessary to increase the structural strength in terms of seismic safety. .

  On the other hand, when the target 2 installed in front of the stopping device moves in the left-right direction, or shooting training in which the shooter fires in the entire circumferential direction without specifying the position of the target 2 as a shooting target The field and its stopping device have not been studied at all.

  This invention makes it the 1st subject to provide the shooting training apparatus which an shooter can shoot toward the perimeter direction.

  Moreover, this invention makes it a 2nd subject to provide a bullet stopping device which suppresses environmental pollution, and has high durability, and a shooting training field provided with the same.

  In order to solve the above-mentioned problems, the shooting training field of the present invention is characterized in that a bullet stopping device that captures an actual bullet of a firearm is continuously provided so as to surround the shooter. In this way, if the structure in which the stopping device is provided continuously, it can cope with shooting training in the case where the target moves in the left-right direction, and by surrounding the shooter, the shooter can shoot in the entire circumferential direction. It becomes possible to do.

  In this case, the bullet stopping device is configured to capture the fired bullet of the firearm with an elastic and viscous material having elasticity and viscosity. That is, by forming the region for capturing the bullets with an elastic material, the impact force of the bullets upon landing can be absorbed, and the bullets can be prevented from being crushed and damaged to the support members. Moreover, since the bullets are not crushed at the time of landing, environmental pollution of the shooting training field can be prevented.

  The bullet stopping device is characterized in that at least the front surface on the shooter side of the container is formed of an elastic member and the container is filled with a granular member. Here, the upper part of the stopping device is provided with the inlet for the granular member and the outlet for the granular member at the lower part.

  According to this, the bullet which penetrated the bullet viscous member is captured by the granular member, and the captured bullet can be discharged from the discharge port together with the granular member. In other words, the bullet captured in the bullet stopping device is discharged, and the granular member is newly supplied from the insertion port, so that the bullet capturing performance of the bullet stopping device can be maintained for a long time and the durability of the device can be improved.

  Here, the elastic-viscous member is formed by stacking concave members having concave portions on the surface opposite to the archer, and the leg portions on both sides of the concave members are connected to the rear wall surface of the container via a support member. Configure as follows. In this way, if the elastic members are stacked in a plate shape or block shape and are connected to the rear wall surface to hold the horizontal force, the internal pressure of the granular member held inside will be handled by each. It is possible to prevent swelling of the elastic viscous member. Further, according to this configuration, since the horizontal excitation force at the time of an earthquake can be dispersed, the seismic strength is increased, and further, the structural strength of the frame can be reduced.

  Here, the elastic-viscous member preferably includes any one or more of elastic rubber, plastic, reinforcing fiber cloth or mesh material, and composite materials thereof. The elastic-viscous member is formed by molding a fiber-like or granular chip made of elastic rubber or plastic with a binder, and preferably has a porosity of 20 to 40%.

  Further, it is preferable that the bullet stopping device is provided with a bulletproof structural member at the upper part on the shooter side of the rear wall surface. That is, since the bulk of the granular member gradually becomes smaller along with the particle size due to friction with the bullet at the time of landing, there is a possibility that when the space is opened in the upper part in the container, the upper part is struck. Therefore, for example, by forming a bulletproof structure member such as a plate shape or a block shape on the rear wall surface, it is possible to maintain the filling height of the filling layer of the granular member and prevent bullets from jumping.

  Further, in the stopping device, the side surfaces of the elastic viscous members of the adjacent stopping devices are in contact with each other, and this side surface has a bent portion that bends in the front-rear direction, while the contact surfaces of the stacked concave members are horizontal. It is preferable to have an angle with respect to the direction. According to this, intrusion of the bullets that have landed on the contact surfaces of the elastic-viscous members can be suppressed.

  Furthermore, it is preferable to set the thickness in the bullet penetration direction in the packed layer of the granular member based on the kinetic energy of the bullets fired by the firearm. According to this, the depth dimension of the bullet stopping device can be set according to the power of the firearm used, so that the device does not increase in size unnecessarily, and the bullet passes through the packed bed and crushes the rear wall surface. There is nothing.

  According to the shooting training apparatus of the present invention, the shooter can shoot toward the entire circumference. In addition to this, it is possible to provide a bullet stopping device that suppresses environmental pollution and has high durability, and a shooting training field including the same.

  Hereinafter, a first embodiment according to the present invention will be described with reference to the drawings. FIG. 2 is a plan view of an example of a shooting range to which the bullet stopping device 10 according to the present embodiment is applied. As shown in the drawing, a plurality of bullet stopping devices 10 are arranged adjacent to each other so as to surround a periphery where the shooter 1 shoots toward the target 2. The target 2 may be provided with a target driving device 7 or a bullet pier 6 shown in FIG. In this case, the target 2 can be set to operate so as to appear in a hidden state in addition to a fixed target as a shooting target, for example, in the left-right direction, the front-rear direction, and the combined movement thereof.

  As shown in the figure, the entrance of the shooter 1 (trainer) to the shooting range is provided by opening it at a location where the bullet does not reach directly, or by moving part of the pier to provide the entrance. Good.

  According to this shooting range, in addition to being able to carry out shooting training in which the shooter 1 shoots at the target 2 as an arbitrary shooting target, bullets that have been missed from the target 2 due to misfiring are installed in all directions. Therefore, the safety of the training is ensured. Note that the shooting range is not limited to the rectangular shape shown in the figure, and can correspond to, for example, a circular shape or a polygonal shape.

  FIG. 3 is a side cross-sectional view of the bullet stopping device 10 in which the cross-section taken along the arrow A in FIG. 2 is enlarged. The stopping device 10 of the present embodiment can be installed on the back of the target 2 in the conventional shooting range shown in FIG. 13 or FIG. The bullet stopping device 10 is provided along the wall surface 11 and the floor surface 12 of the shooting range building, and connects an elastic viscous member 13 having a concave portion in the vertical direction to a frame 14 formed on the shooter 1 side of the wall surface 11. The space surrounded by these is filled with the granular member 15. The elastic-viscous member 13 is formed by stacking a plurality of plate-like or block-like concave members 16 in the vertical direction, and each concave member 16 has a leg portion on both sides connected to the frame 14 by support members described later.

  The top of the bullet stopping device 10 is opened, and an insertion port 17 into which the granular member 15 is inserted is formed. A plate-shaped bullet-proof structural member 18 is mounted on the frame 14 for the insertion port 17 so as to narrow the opening cross section near the insertion port. The bullet-proof structural member 18 is formed in response to the fact that it becomes easy to bounce upward as a result of the bulk with the particle size of the granular member 15 and the expansion of the upper space due to friction with the bullets that land. On the other hand, a discharge port 19 for discharging the granular member 15 is formed at the bottom of the bullet stopping device 10 by opening a gap between the frame 14 that supports the elastic-viscous member 13 from below and the floor surface 12. The discharge port 19 is normally closed with a block 20.

  FIG. 4 is a side cross-sectional view of the bullet stopping device 10 in which the cross section taken along the line B-B in FIG. 2 is enlarged, and shows a configuration for holding the horizontal force between the elastic viscous member 13 and the frame 14. The concave member 16 constituting the elastic-viscous member 13 is fixed to the frame 14 by providing through holes in the upper and lower leg portions and connecting to the support member through the connecting pins 21.

  Next, the structure in which the elastic member 13 is fixed to the frame 14 will be described in detail. FIGS. 5A to 5D are partial perspective views showing a detailed structure in which the elastic member 13 is fixed to the frame 14. In FIG. 5, the granular member 15 filled inside and the central part of the frame are omitted.

  First, as shown in FIG. 5D, the frame 14 is fixed to the wall surface 11 and the floor surface 12 of the shooting range building, and the support member 22 that holds the horizontal force during an earthquake or the like is attached to the wall surface 11 side. The frame 14 is installed on the frame 14. As shown in FIGS. 5B and 5C, the concave members 16 are alternately stacked on the frame 14 of the floor surface 12 with the support members 22 interposed therebetween, and are connected by connecting pins 21. Thereby, the frame 14 and the concave member 16 are connected in the horizontal direction in each layer, and a space is formed between the frame 14 and the concave member 16, that is, the elastic-viscous member 13. This space is filled with a granular member 15 to constitute a bullet stopping device 10.

  The block 20 shown in FIG. 5A serves as a cover for the discharge port for taking out the internal granular member 15. For this reason, the bullet caught in the stopping device 10 can be discharged to the outside together with the granular member 15 from the lower discharge port 19, and the granular member 15 from which the bullet has been recovered can be returned to the input port 17 again as a recycled material. The block 20 can be provided with a bullet capturing function by being made of the same material as the elastic viscous member 13.

  FIG. 1 is a perspective view showing a part of a shooting training field in which the stopping device 10 of the present embodiment is installed. As shown in the figure, the bullet stopping device 10 in which a granular member (a chip-like elastic viscous member in this embodiment) 15 is filled in a container composed of a frame 14 and an elastic viscous member 13 in which concave members 16 are stacked is a wall surface. A plurality of lines 11 are provided. The stopping device 10 is disposed with the side surfaces of the elastic viscous members 13 of the adjacent stopping devices 10 in contact with each other.

  In the shooting training apparatus having such a configuration, for example, in a shooting field where the target position is not determined, or in a shooting range where the target 2 is moved back and forth and left and right with respect to the shooter 1, the landing position of the bullet on the stopping device and The direction cannot be specified. Therefore, assuming such a case, the bullet catching mechanism of the present embodiment will be described.

  FIG. 6 is a horizontal cross-sectional view showing several aspects in which a bullet is captured by the bullet stopping device 10. The fired bullet 8 lands on the elastic viscous member 13 and stops after the kinetic energy is attenuated by friction with the elastic viscous member 13. Here, when the bullet does not concentrate on one place of the bullet-viscosity member 13, the bullet stop distance L1 (X1, X2) in the bullet-viscosity member 13 shows a substantially constant distance due to the kinetic energy of the bullet. Further, when the bullets land in the vicinity of the horizontal joint surface between adjacent elastic members 13 (X3) and land along the horizontal joint portion of the elastic members 13 (X5), the bullet stop distance is Compared with the case of passing through the elastic-viscous member 13, the resistance to pass through the joint is small, and therefore L1 <L2 <L4. Therefore, by selecting the horizontal shooting direction thickness D1 of the elastic viscous member 13 as D1 <L1, the bullet 8 can be captured in a state of reaching the inside of the granular member 15 (X4).

  On the other hand, in the shooting training with firearms, the bullet 8 is shot at the center of the human torso (for example, 0.4 m above and below about 1.4 m above the floor, in order to shoot the target 2 of a human size assuming an enemy or a criminal. Concentration). As described above, when the landing of the elastic viscous member 13 is concentrated, the elastic viscous member 13 is damaged or partially lost, and the resistance force that prevents the bullet from passing is reduced. Therefore, the bullet catching mechanism becomes bullet capture by friction between the granular member 15 and the bullet 8, and the stop distance at the granular member 15 is L6 (Y1). In the case of the bullet capture by the granular member 15, even if the landing is concentrated, the bullet passage path is always blocked by the granular member 15 due to the fluidity of the granular member 15, so that the bullet that has entered next is similarly stopped at the stop distance L6. (Y1). Thus, if the shooting direction thickness D2 of the granular member 15 is selected such that D2> L6, the bullet 8 can be captured inside the granular member 15.

  Thus, if the thickness of the granular member 15 is appropriately selected, even if the elastic viscous member 13 is damaged, the landed bullet 8 is decelerated and captured by the granular member 15, so the elastic viscous member 13 of the bullet stopping device 10. This damage will not affect bullet capture performance.

  Further, the landing concentration portion in the elastic viscous member 13 can be captured inside the granular member 15 by the above-described capturing mechanism until the phenomenon that the internal granular member 15 leaks to the outside occurs. When the loss due to the landing of the elastic-viscous member 13 is large, it is possible to form a repair layer 23 by filling with a binder or an adhesive and filling the damaged part or fusion repair of a homogeneous material to fill the hole (Z1). ), And thus the bullet capture performance can be recovered (Z2). Even when the elastic member 13 is lost, the granular member 15 is held within the range of the angle of repose of the granular member 15. Therefore, leakage of the granular member 15 to the outside causes the thickness D1 of the elastic member 13 in the shooting direction. Can be suppressed by appropriate selection.

  The thicknesses D1 and D2 in the shooting direction of the elastic member 13 and the granular member 15 that realize the bullet capturing mechanism as described above need to be appropriately selected according to the kinetic energy of the bullet that performs the shooting, and preferably D1 = 0. It is good to select in the range of 15-0.5 (m) and D2 = 0.2-0.6 (m).

  FIG. 7 shows the use of NATO (North Atlantic Treaty Organization) in each of the granular member 15 made of a chip-like elastic member and the block-like elastic member 13, a 5.56 mm rifle (rifle bullet). It is a graph which shows the result of having actually measured the distance until the bullet of) penetrates and stops. Therefore, it is optimal to select the stopping device 10 when using this firearm as D1 = 0.2 (m) and D2 = 0.4 (m). Further, the horizontal width W0 perpendicular to the shooting direction of the elastic viscous member 13 and the vertical thickness T0 (see FIG. 3) are W0> 0.7 (m) in consideration of repair exchangeability due to concentration of the bullets 8. ) And T0 = 0.05 to 0.5 (m) are preferable, and practically W0 = 1.0 to 1.5 (m) and T0 = 0.1 to 0 It is better to select within the range of 2 (m).

  The material of the elastic member 13 includes any one or more of elastic rubber, plastic, reinforcing fiber cloth or mesh material, and these composite materials, and has a plate-like or block-like shape. The structure is formed by stacking things, fiber-like or granular chips of these elastic materials are molded with a binder, and the ones having a plate-like or block-like shape with a porosity of 20 to 40% are stacked. What is to be done is suitable.

  Moreover, it is preferable that the shape of the side surface with which the elastic member 13 adjacent to the elastic member 13 abuts is a structure that prevents the straight movement of the bullet as indicated by X5 in FIG. In this way, by providing the bent portion on the side surface, in order to suppress the intrusion of the bullet 8 that has landed in the gap between the elastic viscous members 13, the bullet 8 reaches the frame 14 through the gap with less kinetic energy resistance. It is possible to prevent the bullets from being broken and the frame 14 from being damaged.

  Thus, according to the configuration of the present embodiment, the bullet stopping device 10 can be arranged so as to surround the archer 1, so that the shooter 1 can shoot in the entire circumferential direction. And since the bullet stopping device 10 of this embodiment captures the bullet 8 by the granular member 15, the landed bullet 8 should just discharge | emit regularly with the granular member 15, and supplies the granular member 15 newly. Thus, the crushing phenomenon of the bullets 8 due to the collision between the bullets 8 can be suppressed, and the environmental pollution problem can be reduced. Note that the bullet 8 discharged together with the granular member 15 is separated from the granular member 15 by the separating means, and can be reused.

  Further, the elastic member 13 that covers the granular member 15 from the archer side is laminated as a plate-like or block-like concave member 16, and each concave member 16 is connected to the rear frame 14 so as to be landed or the like. As a result, it is possible to prevent a swelling phenomenon with time due to damage due to the internal pressure or the internal pressure of the granular member 13, thereby improving durability. Further, since the horizontal excitation force at the time of an earthquake can be distributed and held between the respective concave members 16 and the frame 14, not only the strength safety at the time of the earthquake is increased, but also the structural strength of the frame 14 can be reduced.

  When the elastic-viscous member 13 is damaged due to landing, the damaged concave member 16 can be easily replaced, and the severely damaged concave member 16 (for example, around 1.4 m above the floor) and the concave member 16 with relatively little damage. Since it can be used by rearranging, durability is greatly improved and it is economical.

  Further, if the elastic member 13 is damaged by the time it is repaired before the granular member 16 cannot be held, the concave member 16 of that portion needs to be replaced. Since the captured bullet 8 exists, the bullet and the elastic viscous member 13 can be separated by mechanical pulverization. The separated bullet 8 can be reused as a recovered resource, and can be regenerated by remolding the material constituting the pulverized elastic viscous member 13.

  Next, a second embodiment according to the present invention will be described with reference to FIG. FIG. 8 is a view showing a cross-sectional configuration in the horizontal direction with respect to the shooting direction of the bullet stopping device 10 to which the present invention is applied. In the first embodiment, the shape between the elastic member 13 and the adjacent elastic member 13 has a structure for preventing the straight movement of the bullet 8 as indicated by X5 in FIG. A straight movement preventing structure for the bullet 8 having bent portions as shown by d1 to d5 can be provided on the contact surface of the elastic viscous member 13. The shape of the contact surface is not limited to these as long as it prevents the bullet 8 from entering.

  Next, a third embodiment according to the present invention will be described with reference to FIG. FIG. 9 is a diagram showing a partial cross-sectional configuration in the vertical direction with respect to the shooting direction of the bullet stopping device 10 to which the present invention is applied. As shown in the figure, the surfaces where the concave members 16 constituting the elastic-viscous member 13 abut each other form a bent portion that prevents the bullet 8 from going straight except for e2, and e2 is in the horizontal direction toward the archer side. By having an angle so as to be lifted from, the bullet 8 is prevented from entering. The shape of the contact surface is not limited to these as long as it prevents the bullet 8 from entering. In addition to the present embodiment, it is more effective to provide a straight-line blocking structure for the bullet 8 as shown in FIG.

  Next, a fourth embodiment according to the present invention will be described with reference to FIG. FIG. 10 shows a cross-sectional configuration in the vertical direction with respect to the shooting direction of the bullet stopping device 10 to which the present invention is applied. By providing the outlet 24 of the granular member 15 at the lower back of the bullet stopping device 10, the surface on the archer 1 side becomes a uniform surface of the elastic viscous member 13, and the inside of the shooting field can be used efficiently.

  Next, a fifth embodiment according to the present invention will be described with reference to FIG. FIGS. 11A to 11D are partial perspective views showing a detailed structure in which the elastic member 13 is connected to the frame 14. In FIG. 11, the central part of the granular member 15 and the frame 14 filled therein are omitted.

  As shown in FIG. 11D, the frame 14 is fixed to the wall surface 11 and the floor surface 12 of the shooting range building, and the support member 25 that holds the horizontal force at the time of the earthquake is attached to the wall surface 11 of the shooting range building. It is structured to be installed on a fixed frame 14.

By stacking, the frame 14 and the concave member 26 are connected horizontally in each layer, and a space is formed between the frame 14 and the concave member 26, that is, the elastic member 13. The bullet stopping device 10 can be configured by filling the space with the granular member 15. Other configurations are the same as those described with reference to FIG.

  FIG. 12 is a cross-sectional view taken along the arrow E in FIG. As shown in FIG. 12A, the concave member 26 is stacked in a state where the leg portion is engaged with the claw portion 27 of the support member 25. In other words, the concave member 26 is connected to the frame 14 in the horizontal direction in each layer in the same manner as the fixing method using the connecting pin 21 described above, and the horizontal force is maintained. As shown in FIGS. 12B and 12C, the concave member 26 can be removed by lifting the concave member 26 arranged at the uppermost stage to release the connection with the claw portion 27 and pulling it forward. .

  As described above, specific examples of the method of connecting the elastic-viscous member to the frame 14 have been described, such as the method using the connection pin 21 and the engagement with the claws. However, the present invention is not limited to these examples. It is preferable to select an optimal configuration as appropriate according to the usage.

  In addition, although the flame | frame 14 in embodiment mentioned above has demonstrated as a structure where all are fixed to the wall surface 11 of a shooting range building, the flame | frame 14 is also independent as a structure installed from the floor surface 12 of a shooting range building.
