Abstract

PURPOSE: To provide a bullet stopping apparatus in which the ricochet from a bullet stop bank or a back surface is effectively prevented, the safety of a shooter is ensured, the recovery of the bullet is facilitated and shooting training from a point-black range is performed. CONSTITUTION: Since the impact force of a bullet 6 can be diffused and absorbed by a high tensile member 9 in which a plurality of layers of cloth woven by high tensile fiber are laminated, plastic deformation member 10, viscoelastic member 11 and hard member 12, etc., the penetration of the bullet is prevented, and hence a bobbing driver can be protected. Since the ricochet from a bullet stop bank or the back surface of a target can be effectively prevented, the shooter's safety can be obtained, and shooting training from a point-black range can be performed. Further, since the bullet 6 does not penetrate a bullet stop member 21 to effectively diffuse the impact force and to absorb it to the bullet stopping unit, the unit can be continuously used. Moreover, since the bullet 6 is not disintegrated, plastically deformed and dropped to the floor without scattering to the front surface (shooter side), the recovery and cleaning of the bullet can be effectively conducted.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stopping device, for example, a stopping device in a shooting training system used for live shooting training (hereinafter referred to as shooting training) with a pistol or a rifle of a police officer or a self-defense officer. Regarding

[0002]

2. Description of the Related Art A conventional shooting training device is shown in FIGS. In addition, a layout of a general shooting training field is shown in FIG. Shooter 1 as shown in FIG.
Trains to fire a bullet on the target 2. A stop levee 5 is arranged in front of the target 2 and a stop member 23 is arranged behind it. Further, as shown in FIG. 25, the shooter 1 stands on the floor 8 at a distance L ₁ from the target 2 and shoots a bullet 6 toward the target 2 with a pistol or a rifle 3. L ₁ is usually in the range of 5 to 50 m for pistol shooting. In the shooting training, the target 2 may be made to perform a covert movement in order to improve the instantaneous shooting determination ability. The revealing operation is an operation of rotating the target 2 in the direction of arrow A as shown in FIG. 27 to show or hide the target surface to the shooter. In order to perform this covert movement, a covert movement drive device 4 is installed below the target 2.

As shown in FIG. 25, a bullet stop 5 is provided in front of the covert operation drive device 4 in order to prevent the bullet 6 from being damaged by being hit by the bullet 6. When the shooter 1 accidentally fires a bullet 6 in the direction of the hidden movement driving device 4, the bullet dam 5 bounces the bullet 6 as shown by an arrow B.
The covert movement drive device 4 is protected from the bullet 6. A steel plate having a thickness and rigidity that does not allow the bullets 6 to penetrate therethrough is generally used for the bullet levee 5. Further, as shown in FIG. 26, a sandbag (a bag containing soil) 24 is provided in front of the covert movement driving device 4 in order to prevent the bullet 6 from being damaged by being hit.
May be placed in a stack. When the shooter 1 accidentally fires the bullet 6 in the direction of the hidden movement driving device 4, the sandbag 24 holds the bullet 6 in the sandbag 24 as indicated by arrow B.
By keeping it inside, the covert movement drive device 4 is protected from the bullet 6. In this way, conventionally, the breakwater 5 and sandbags 24
Was installed to protect the invisible motion drive device 4 and the like and prevent damage to the device.

[0004]

However, in the above-mentioned prior art, although the objective of the protection of the hidden operation driving device 4 can be achieved, the safety of the shooter 1 from the bullet of the bullet 6 and the scattering of the bullet 6 to a wide range by the bullet are scattered. No consideration was given to the recovery of bullets 6 that were made. In the case of the breakwater 5 shown in FIG. 25, the bullet 6 has a distance L ₂ from the target 2 as indicated by an arrow B.
May bounce up to. In the case of pistol shooting, the distance L ₂ is usually in the range of maximum 11 m to 15 m. To prevent the shooter 1 from hitting the ricochet, the target 2
The distance L ₁ from the shooter to the shooter 1 must be L ₁ > L ₂ . Since the breakwater 5 is made of a steel plate having high rigidity, the distance L ₂ becomes large. Therefore, in order to ensure the safety of the shooter 1, the distance L ₁ also needs to be made large, and shooting training from a close range is performed. It was unsuitable for the location, especially the indoor shooting range. Further, since the bullets 6 are scattered on a wide area of the floor 8 in front, there is a drawback that it takes time to collect the bullets after shooting training.

When the stop sandbag 24 shown in FIG. 26 is used, the possibility of ricochet is eliminated, and it is possible to shoot from a close range, but the bullet 6 stays in the sandbag 24 due to the resistance of the soil. After the shooting training, there was a drawback that it took time to collect the bullets 6 in the sandbag 24 and repair the bag. Moreover, since the soil may scatter from the sandbag 24, it was not suitable for indoor shooting training grounds. It is an object of the present invention to protect a sigmoid movement driving device by blocking bullet penetration with a simple bullet stopping device. Further, an object of the present invention is to effectively prevent a bullet from a bullet bank or a back surface of a bullet stopping device, ensure the safety of a shooter, and enable shooting from a close range. It is also an object of the invention to allow continuous use of the ballistic stopping device. Further, an object of the present invention is to provide a stopping device capable of efficiently collecting and cleaning bullets.

Further, according to the present invention, in any one of the above-mentioned bullet stopping devices, a gap may be further provided at a front portion of the high tension member, and at least one bullet preventing member is arranged for preventing a bullet. Further, according to the present invention, a gap is provided at a front portion of any one of the bullet stopping devices, at least one bullet preventing member is arranged for preventing a bullet, and a groove for collecting a bullet is provided below a front portion of the bullet stopping member. It may be configured. Furthermore, the present invention may be a bullet stopping device in which a hard member for stopping bullets (such as a metal plate) and a front portion thereof are provided with a gap and at least one bullet preventing member is arranged for preventing bullets. Further, according to the present invention, a hard member for stopping a bullet is provided, a gap is provided in the front portion thereof, at least one bullet preventing member is arranged for preventing a bullet, and a groove for collecting a bullet is provided below a front portion of the hard member. It may be configured.

Further, the present invention may have a constitution in which a hard member for stopping a bullet is further provided at the rear of any one of the above stopping devices. At this time, a configuration in which a gap is provided in the front portion of the hard member and at least one ricochet preventing member is arranged for preventing ricochet is also within the scope of the present invention. According to the present invention, at least one ricochet preventing member is arranged with a gap behind any of the bullet stopping devices, and a hard member for stopping a bullet is arranged behind the ricochet preventing member with a gap. It may be a bullet stop device. The high-tension member of the present invention uses high-tension fibers made of polyamide fiber, glass fiber, carbon fiber or the like. A fiber having a tensile strength of 20 gf / D (denier) or more is a desirable fiber because it has such a tensile strength that the fiber is not cut against the elongation of the fiber when hit by a bullet.

As the plastically deformable member of the present invention, various synthetic resin plates or wood plates are used. Among them, the ultra high molecular weight polyethylene resin has toughness that does not break or penetrate by the impact force of a bullet and has an appropriate hardness. Material is preferable. As the viscous bullet member of the present invention, for example, a gel-like material containing silicone as a main material having elastic force and large internal damping is preferable.

As the rubber plate, rubber made of a material having high elasticity and toughness such as natural rubber, styrene-butadiene rubber (SBR), and neoprene rubber is preferably used. As the rubber plate laminated between the high-tensile member and the plastically deformable member, the rubber plate listed as the above-mentioned jump preventing member is used.

[0011]

According to the above configuration of the present invention, a high-tensile member, a plastically deformable member, and a plurality of fabrics woven of high-tensile fibers are laminated.
Disperses the impact force of bullets with viscoelastic members, hard members, etc.
Since it can be absorbed, penetration of bullets is prevented, and thus the Oki movement driving device can be protected. In addition, since it is possible to effectively prevent a bullet from the stop levee or the back of the target, it is possible to ensure the safety of the shooter and to perform shooting training from a close range. Furthermore, since the bullet does not penetrate the stopping device and the impact force is effectively diffused and absorbed by the stopping device, this device can be continuously used. Further, the bullet does not self-destruct, it plastically deforms, and does not scatter on the front surface (shooter side) and falls on the floor surface, so that the bullet can be efficiently collected and cleaned.

The operation of each component will be described below. First, when the high-tensile member hits a bullet, it has an action of diffusing the energy of the bullet by the tension of the fiber. Further, the plastically deformable member has an energy absorbing action and an energy diffusing action of the bullet energy due to the plastic deformation. The viscoelastic member has a bullet energy absorbing action due to an internal damping action. Further, the hard member has an effect of preventing penetration of bullets (stoppage) by itself, and is provided for accident prevention. According to the ballistic stopping device of the present invention, the plastic deformation member is arranged on the back surface of the high-tensile member, and when the bullet hits the high-tensile member, the plastic deformation of the bullet is attempted to enter the inside of the plastic deformation member. Since the member is limited to its partial plastic deformation, the elongation of the fiber of the high tensile member can be suppressed below the allowable shear stress. Further, a viscoelastic member is arranged on the back surface of the plastically deformable member, and since the energy of the bullet can be transmitted to the viscoelastic member in a wide range of the surface of the plastically deformable member, the effect of absorbing energy of the bullet by the viscoelastic member is large, The risk of ricochet is reduced. Further, due to the energy absorption effect, the bullet does not self-destruct and plastically deforms at the collision position, so that the high tension member is not damaged.

When the arrangement of the plastically deformable member and the viscoelastic member is reversed from that of the present invention, that is, when the plastically deformable member is arranged on the back surface of the viscoelastic member, when the bullet hits the high tension member. Since the bullets try to enter the inside of the viscoelastic member, the fibers of the high-strength member are excessively elongated, and the fibers exceed the permissible shear stress and break, so that the object of the present invention is not achieved. Also, by arranging at least one ricochet-preventing member such as a rubber plate on the front surface (shooter) side with a gap sufficient for the bullet to fall, the bullet does not scatter, and below the ricochet-preventing member. Since it falls, the collectability of bullets improves,
Easy to clean. Furthermore, by providing the groove below, the collectability of bullets is further improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The same parts as those in the conventional technique shown in FIGS. 25 to 27 are designated by the same reference numerals. First Embodiment FIG. 1 shows a cross-sectional view of a first embodiment of a bullet stopping device of the present invention.
The ballistic stop device of the present embodiment is a high-tensile member 9 having a thickness of 3 mm (thickness of six laminated layers) obtained by laminating six fabrics woven of high-tensile fibers made of polyamide fibers (trade name: Kevlar, manufactured by DuPont). , A plastic deformation member 10 made of ultra-high molecular weight polyethylene (trade name: MEPUHMW, manufactured by Mitsuboshi Belting Co., Ltd.) having a thickness of 15 mm; a gel-like substance mainly made of silicone having a thickness of 15 mm (trade name: α-gel, Siegel Co., Ltd.) Made of a viscoelastic member 11 and a stainless steel plate with a thickness of 2 mm (SUS
The hard member 12 made of 420F) is sequentially stacked to form the ball stop member 21.

In the following examples, the same members are designated by the same reference numerals and the same chemical substances or compositions are used.

This bullet stopping device diffuses the energy of the bullet 6 by the tension of the fibers forming the high tension member 9, and absorbs the energy by the plastic deformation of the plastic deformation member 10.
Further, by absorbing energy by viscoelastic deformation of the viscoelastic member 11, the bullet 6 from the arrow C direction can be effectively stopped at the front surface of the high tension member 9. In addition, the bullet 6 is formed by the plastically deformable member 10 and the viscoelastic member 11.
Since the energy of is absorbed, the risk of a ricochet is extremely low. FIG. 2 and FIG. 3 are diagrams schematically showing how a ricochet is performed. According to the present embodiment, the distance L ₃ of the bullet is about 3 m, and the bullet 6 formed by the plastic deformation member 10 and the viscoelastic member 11 is used.
Due to the energy absorption effect of (1), the value is far smaller than the conventional distance L _{2 of} about 11 to 15 m of the ricochet described in the embodiment, and the shooting training at a close range becomes possible.

Second Embodiment A second embodiment is shown in FIG. The second embodiment has a structure in which a rubber plate 13 (natural rubber) having a thickness of 3 mm for preventing ricochet is arranged in front of a bullet stopping device composed only of the bullet stopping member 21 of the first embodiment with a gap. By providing the rubber plate 13 for preventing jumping on the front surface of the bullet stopping device of the first embodiment, the effect of preventing jumping is further enhanced. In addition, the rubber plate 13 covers the upper part of the stopping device 21 as shown in FIGS.
What is adhered to the back surface of is a structure that is practically advantageous. 5 and 6 schematically show how a bullet is shot, the bullet 6 penetrates the rubber plate 13 and hits the high tension member 9, and the slightly bounced bullet 6 is bounced back by the rubber plate 13 Board 1
3 to the floor 8 between the high tension member 9. in this way,
The rubber plate 13 enhances the ricochet prevention effect, but it is also an effect that the bullet 6 can be easily recovered after shooting training because the bullet 6 does not scatter. It should be noted that the rubber plates 13 may be used by stacking a plurality of them in order to increase the effect of preventing ricochet.

Third Embodiment FIG. 7 shows a third embodiment of the bullet stopping device of the present invention. FIG. 7 is a cross-sectional view of the high-strength member 9 in which a plurality of fabrics woven of high-tensile fibers made of polyamide fiber are laminated, and the thickness is 2 m.
m rubber plate 14 made of natural rubber, plastically deformable member 10,
This is a bullet stopping device including a bullet stopping member 21 in which a viscoelastic member 11 and a hard member 12 are sequentially laminated. This bullet stopping device diffuses the energy of the bullet 6 by the tension of the fibers constituting the high tension member 9, and further the energy is diffused by the viscoelastic deformation of the rubber plate 14, so that the plasticity is the same as that of the first embodiment. The deforming member 10 and the viscoelastic member 11 can absorb the energy of the bullet 6 and effectively stop the bullet 6 from the direction of the arrow C on the front surface of the high tension member 9. Moreover, the rubber plate 14
Energy is diffused by the plastic deformation member 1
0, since the energy of the bullet 6 is absorbed by the viscoelastic member 11, there is very little risk of ripping.

The third embodiment will be described below with reference to FIGS. 8 to 11 in order to clarify the difference between the third embodiment and the first embodiment. 8 and 9 are a sectional view and a front view, respectively, showing a state at the moment when the bullet 6 hits the bullet stopping device of the first embodiment, and FIGS. 10 and 11 show the bullet stopping device of the third embodiment. It is sectional drawing and front view which show the state at the moment of the bullet 6 hit. Since the energy stopping rubber plate 14 is provided between the high tension member 9 and the plastically deformable member 10 in the bullet stopping device of the third embodiment, stress is less likely to concentrate near the tip of the bullet 6, and the life of the high tension member 9 is reduced. Has the effect of being longer than the ballistic stopping device of the first embodiment. When a stainless steel plate having a thickness of 2 mm is used instead of the plastically deformable member 10, the impact energy of the bullet is not diffused due to the high rigidity of the stainless steel plate, so that the stress concentration on the high tension member 9 at the tip of the bullet 6 occurs. It has been confirmed that the high tension member 9 is broken when it occurs. That is, it is understood that stress concentration should be avoided as much as possible in order to prevent damage to the high tension member 9. The rubber plate 14 is preferably made of a material having high elasticity and toughness such as natural rubber. The thickness of the rubber plate 14 must be set so that the fibers of the high-tension member 9 are deformed by the bullet 6 and become within the allowable shear stress of the fibers when expanded. For example, it has been confirmed that when the thickness of the rubber plate 14 is set to about 60 mm, the bulletproof fiber is excessively stretched, exceeds the allowable shear stress of the fiber, and the fiber is cut. In this embodiment, the rubber plate 14 having a thickness of about 2 mm is used, but good results are obtained without breaking the bulletproof fiber.

Fourth Embodiment FIG. 12 shows a stopping device according to a fourth embodiment of the present invention. The fourth embodiment has a structure in which a rubber plate 13 for preventing ricochet is arranged in the front portion of the stopping device of the third embodiment with a gap, and with this structure, similar to the second embodiment, a ricochet preventing effect is obtained. It can be much larger. It should be noted that the rubber plates 13 may be used by stacking a plurality of them in order to increase the effect of preventing ricochet. Also,
As with the second embodiment shown in FIGS. 5 and 6, it is practical that the rubber plate 13 covers the upper portion of the stop member 21 and adheres it to the back surface of the hard member 12. Alternatively, they may be fixed by screwing.

Fifth Embodiment FIG. 13 shows a stopping device according to a fifth embodiment. FIG. 13 is a cross-sectional view of the high-strength member 9 in which a plurality of fabrics woven of high-strength fibers made of polyamide fibers are laminated, a rubber adhesive (trade name: ThreeBond 1501, manufactured by ThreeBond Co., Ltd.)
This is a ballistic stopping device comprising a ballistic stopping member 21 in which the adhesive layer 15, the plastic deformation member 10, the viscoelastic member 11, and the hard member 12 are sequentially laminated. The bullet stopping device of the present embodiment diffuses the energy of the bullet 6 by the tension of the fibers forming the high tension member 9, and further diffuses the energy by viscoelastic deformation of the adhesive layer 15 of the rubber adhesive. Similar to the first and third embodiments, the plastic deformation member 10 and the viscoelastic member 11 absorb the energy of the bullet 6 to effectively stop the bullet 6 from the direction of arrow C on the front surface of the high tension member 9. Can be bulleted. In addition, since the energy is diffused by the adhesive layer 15 of the rubber-based adhesive and the energy of the bullet 6 is absorbed by the plastic deformation member 10 and the viscoelastic member 11, the risk of ripping is extremely small. Also in this embodiment, the stress concentration is reduced due to the energy diffusion effect of the adhesive layer 15 of the rubber-based adhesive, and the high-strength member 9 is higher than that of the bullet stopping device of the first embodiment.
Lifespan is extended.

Comparative Example A bullet stopping device was manufactured by using a steel plate instead of the plastically deformable member 10 of the first embodiment. Using the bullet stopping device of the first, third and fifth embodiments and the bullet stopping device of the comparative example, bullets 6
The degree of stress concentration and the degree of damage to the high-tension member 9 when hit by the eye were visually observed. Table 1 shows the results.

[Table 1]

The structure is such that a gap is provided in the front portion of No. 1, and this structure can further enhance the ricochet prevention effect as in the second and fourth embodiments. It should be noted that the rubber plates 13 may be used by stacking a plurality of them in order to increase the effect of preventing ricochet. Further, the rubber plate 13 is not shown in the figure, as in the second embodiment shown in FIGS.
It is also possible to cover the upper part of 1 and adhere to the back surface of the hard member 12.

Seventh Embodiment FIG. 15 shows a seventh embodiment of the bullet stopping device of the present invention. In this embodiment, a rubber plate 1 for preventing a bullet is formed by making a gap in the front portion of a bullet stopping member 21 made of a steel plate having a thickness that does not allow the bullet 6 to penetrate.
3 is arranged, and it is possible to prevent a ricochet. In addition, in order to increase the effect of preventing ricochet, a plurality of rubber plates 13 may be stacked and used. The use of a steel plate for the stop member 21 has an advantage that the cost can be reduced because the structure is simple as compared with the other embodiments, but the weight is heavy. Also,
As shown in FIGS. 16 and 17, the rubber plate 13 has a stop member 21.
It may be one that covers the upper part of the above and is bonded to the back surface of the bullet stopping member 21. Alternatively, they may be fixed by screwing. 16,
FIG. 17 schematically shows the state of a ricochet, but the bullet 6 penetrates the rubber plate 13 and hits the stop member 21 made of a steel plate, and the bullet 6 that has bounced falls to the floor 8 by the rubber plate 13.
In this way, the rubber plate 13 of the present embodiment allows the second embodiment,
Similar to the fourth and sixth embodiments, there is a ricochet prevention effect.
