Description

{A panel for preventing from ricochet bullet}

The present invention relates to an anti-scattering panel, and more specifically, to an anti-scattering panel, which enables easy separation of a damaged or broken panel during reinstallation or repair of a damaged or broken anti-scattering panel, makes assembly of the panel simple, and enables installation and disassembly at any location during repair.

Military and police agencies that handle firearms conduct live-fire training at indoor and outdoor live-fire shooting ranges to improve the shooting skills of their personnel.

In addition, as the general public has more free time and the range of leisure activities has expanded, more and more people are visiting general live-fire shooting ranges to enjoy live-fire shooting.

However, when shooting live ammunition, unexpected ricochets (a bullet that deviates from its original trajectory after hitting an obstacle in the middle of its flight after being fired from a gun; also called a ricochet bullet) can occur, which can cause serious injuries to users or even threaten their lives.

Furthermore, as the age for entry into live-fire shooting ranges for the general public has been lowered to 14, anyone over the age of 14 can now enter live-fire shooting ranges, so the safety of users is absolutely required.

In the past, in live-fire shooting ranges, rubber plates made of rubber chips were used to attach and construct bullet-producing equipment to the rear or side walls of target installation surfaces using a bonding method.

However, the conventional rubber chip-made bullet rubber plates mentioned above were mostly made by relying on imported rubber chips or by reusing waste tires that had been used on open ground such as children's playgrounds for a long time by crushing them into rubber chips.

As a natural consequence of this, the above-mentioned bullet-proof rubber plates not only have short durability, but are also supplied as products with various qualities depending on the amount of binder mixed into the rubber chips during manufacturing or the manufacturing method.

The above conventional anti-slip products were made of various materials and methods and were made into blocks or panels, or by stacking rubber pieces to prevent them from flowing out, and then they were fired, so that the fired bullets remained in the bullet material, and the firing concentration area was easily broken and damaged by the accumulation of spent bullets, and the stacked rubber blocks sometimes overturned, and in winter, the bonding between the rubber chips was also broken by freezing.

In addition, during the summer, the rubber bullet blocks that were attached to the rear or side walls of the target installation surface of a live-fire shooting range by means of a bonding method showed a phenomenon of peeling due to high temperatures, and when fired continuously, the bullets directly hit the plate-like steel plate installed at the rear or other obstacles and bounced, threatening the lives of shooters in very dangerous situations.

The prior art performing the above function is formed as an integral panel shape made of a square NR (natural rubber) or SBR (synthetic rubber) material of a predetermined size, as shown in Korean Patent No. 2022825, and the front, rear, upper and lower surfaces are made of smooth surfaces, and by smoothly accommodating the phenomenon of water leakage and relaxation due to temperature change, the bulletproof steel plate on the rear is prevented from being exposed, thereby preventing the bullet from directly hitting the bulletproof steel plate and causing a ricochet. The left side forms a left jaw and a left contact portion with a predetermined width, and the right side forms a right jaw and a right contact portion with a predetermined width. The width of the left jaw and the width of the right contact portion are formed to be 2/3 of the width of the left and right sides, the width of the right jaw and the width of the left contact portion are formed to be 1/3 of the width of the left and right sides, and the left jaw and the right jaw are extended to a length of 1/2 of the width of the left and right sides. In a bullet-prevention panel for a live-fire shooting range, which is formed by being stacked vertically by its own weight on the front of the bullet-proof steel plate at the rear and connected left and right in a jaw joint manner to form a bullet-prevention wall, a groove of a predetermined width is formed penetrating from the upper surface to the lower surface at corresponding positions between the center of the left jaw of the left side and the center of the right joint of the right side, and a connecting pin is interposed in the groove to prevent the bullet panel from jumping forward when a bullet is concentrated on the bullet panel.

However, the conventional technical configuration had the problem that it was difficult to replace heavy panels because, when reinstalling or repairing a damaged or damaged anti-scattering panel, the top panel that was joined in a sliding manner had to be pulled out upwards and then reattached in reverse order.

In addition, if the power of a live bullet is strong, there is a problem that a bullet penetrating the bullet panel can damage the bulletproof steel plate, and the resonance increases due to the impact of the bullet penetrating the bullet panel on the bulletproof steel plate.

Republic of Korea Patent No. 2022825 (September 18, 2019)

First, as shown in FIGS. 1 to 4, the configuration of the bullet-proof panel for preventing ricochet according to the present invention comprises a bullet-proof steel plate having at least one bracket 210 on which a plurality of connecting pins 211 are installed and a bullet collection box 220 arranged at the bottom, and a bullet-proof panel 100 for preventing ricochet that is fixed to the connecting pins 211 and causes a bullet fired by a shooter to be hit and have its speed attenuated so that it hits the plate steel plate 200. The bullet panel 100 is configured so that the individual assembly and replacement of the bullet panel is possible.

At this time, the bulletproof steel plate 200 is formed of an AR500 material steel plate having a thickness of 10 mm or more and 12 mm or less, and in this example, 12 mm of AR500 material was used.

Here, AR500 bulletproof steel plate is a special wear-resistant steel, and is named after its average Brinell hardness of 450~530, which indicates strength. It is used as the armor plate of the target wall of a shooting range to prevent the bullet fired by the shooter at a live-fire shooting range from penetrating the front. Since the AR500 bulletproof steel plate, which is a special wear-resistant steel, has very high hardness, there is a risk of secondary damage if the bullet hits it due to the bullet breaking or bouncing off. To prevent this, a special coating treatment is applied to reduce the speed of the bullet or a rubber plate is attached to the front to reduce the speed of the bullet.

These bulletproof steel plates 200 are attached and fixed to the front with anchor bolts according to the size of the vertical wall W of a typical indoor live-fire shooting range. The bulletproof steel plates 200 and the wall are tightly sealed, but if there is a gap, it is desirable to fill the gap with soundproofing material (not shown) to reduce noise.

In addition, since the bullet penetrates the bullet-proof panel 100 on the front and is hit by a warhead whose speed is reduced due to the rebound elasticity and restoring force of the penetrating portion, the warhead does not penetrate the bullet-proof steel plate 200 and falls naturally after hitting the bullet-proof steel plate 200.

In addition, the bracket 210 is formed of angle-shaped steel bent into an “L” shape and is vertically attached and fixed to the front surface of the bulletproof steel plate 200 at a predetermined interval horizontally. The fixing method is by welding, but is not limited thereto, and bolt fixing is also possible.

In particular, the gap between the brackets 210 and the brackets 210 that are vertically attached and fixed to the front of the bulletproof steel plate 200 is equal to the horizontal width of the anti-bullet panel 100.

In addition, it is desirable for bracket 210 to have multiple fixing holes (not shown) in the upper and lower directions for the convenience of the installation process in preparation for bolt fixation.

In addition, it is useful to form the bracket 210 into a predetermined unit length for the convenience of the installation process of attaching and fixing it to the indoor wall W of the live-fire shooting range.

In this embodiment, the length of the bracket 210 is formed in units of 1 meter, which makes construction very convenient, but is not limited thereto. That is, the length of the bracket 210 may be divided into shorter pieces for installation.

At this time, the connecting pin 211 is formed as a cylindrical rod made of iron.

And the above bullet collection box 220 is attached in a drawer shape to the bottom of the bulletproof steel plate 200.

At this time, the bullet collection box 220 captures the warhead that falls naturally downward without penetrating the bulletproof steel plate 200 at the rear due to the rebound elasticity and restoring force received at the penetration section when the warhead penetrates the anti-ricochet bullet panel 100, thereby reducing its speed. After firing, the warhead captured in the bullet collection box 220 is collected and safely processed and recycled.

In addition, the bullet panel 100 has a catch 110 protruding on one side and a catch groove 120 formed on the other side corresponding to the catch 110. That is, when the catch 110 is assembled so that it overlaps the catch groove 120, the vertical gap of the bullet panel 100 is closed.

Furthermore, the bullet panel 100 is formed with a hinge groove 140 at an angle on the upper portion of the bullet panel 100 so that it can be installed by being inserted at an angle into the connecting pin 211 and then rotated. In addition, a curved engagement groove 150 that is downwardly hooked onto the connecting pin 211 of the hinge groove 140 is formed to correspond to the distance of the connecting pin 211.

Additionally, hinge grooves 140 and engagement grooves 150 are formed on both sides of the bullet panel 100. In addition, an inclined projection 130 extends to the lower portion of the bullet panel 100.

Meanwhile, as illustrated in Fig. 5, the bullet panel 100a may have an inclined surface 160 formed in the same direction on the upper and lower sides. The horizontal gap is closed through the inclined projection 130 and the inclined surface 160.

In addition, as illustrated in FIGS. 6 and 7, the bullet panel 100b may have an insertion groove 170 formed vertically in the center of the back surface into which a bracket 210 is inserted, and a hinge groove 140 and a fastening groove 150 may be formed on both sides of the insertion groove 170.

That is, the hinge groove 140 of the bullet panels 100, 100a, and 100b is inserted into the connecting pin 211 in the direction of the hinge groove 140, and then the lower part of the bullet panels 100, 100a, and 100b is rotated downward around the connecting pin 212. At this time, a plurality of fastening grooves 150 are inserted into the connecting pin 211 and are caught.

Accordingly, since obstacles are not raised, the bullet does not directly hit the bulletproof steel plate 200 or other obstacles at the rear and bounce off, preventing ricochet occurrences. In addition, even if concentrated fire is received, the bullet panel 100 does not pop out and come off in the front, allowing safe live-fire shooting.

In addition, when the warhead fired by the shooter penetrates the target and the bullet panel 100, the speed of the warhead is significantly reduced due to the rebound elasticity and restoring force of the penetrating portion, so when the warhead reaches the bulletproof steel plate 200, it does not penetrate the bulletproof steel plate 200 and naturally falls downward through the gap between the bulletproof panel 100 and the bulletproof steel plate 200 and is captured in the bullethead collection box 220.

After firing, the captured warheads are collected in the drawer-type warhead collection box 220 and processed or recycled, thereby recycling resources and preventing environmental pollution from environmental pollutants contained in the warheads, and in particular, allowing users to enjoy safe shooting.

Finally, the bullet-proof panel 100 according to the embodiment of the present invention is a bullet-proof steel plate having at least one bracket 210 on which a plurality of connecting pins 211 are installed and a bullet collection box 220 arranged at the bottom so that the bullet fired by the shooter is hit and the bullet speed is reduced so that the bullet is hit by the plate steel plate 200, wherein the bullet-proof panel 100 has a hook 110 protruding on one side and a hook groove 120 corresponding to the hook 110 formed on the other side, and the bullet panel can be installed by being inserted obliquely into the connecting pin 211 and then rotated. A hinge groove 140 is formed at an angle on the upper part of 100, and a curved engagement groove 150 that is formed downward of the hinge groove 140 to engage the connecting pin 211 corresponds to the distance between the connecting pins 211, thereby improving maintainability.

Meanwhile, as shown in FIGS. 8 to 13, it further includes a plurality of auxiliary plates 300 positioned between the bulletproof panel 100 and the bulletproof steel plate.

At this time, the auxiliary plate 300 is formed of an iron plate of AR500 material having a thickness of 4 mm to 6 mm, and in this embodiment, 5 mm of AR500 material was used.

First, as shown in FIGS. 8 and 9, an auxiliary pin 213 is coupled to the rear of a connecting pin 211 in the bracket 210. At this time, a guide groove 310 passing through the connecting pin 211 is formed on both sides of the first auxiliary plate 300a. In addition, a plurality of engaging members 320 engaged with the auxiliary pin 213 are installed on the rear surface of the first auxiliary plate 300a. Furthermore, the auxiliary pins 213 are arranged in an inclined direction so that there is no mutual interference between the first auxiliary plates 300a.

In addition, as shown in FIGS. 10 and 11, a fastening member 220 is coupled to the rear of the connecting pin 211 in the bracket 210. At this time, a guide groove 310 passing through the connecting pin 211 is formed in the second auxiliary plate 300b. In addition, a fastening means 320 passes through the second auxiliary plate 300b and is fastened to the fastening member 220.

In addition, as illustrated in FIGS. 12 and 13, a guide groove 310 is formed that extends to the back and side surfaces of the "ㄷ"-shaped third auxiliary plate 300c. The guide groove 310 is caught after passing through the connecting pin 211. At this time, the width is adjusted so that the bullet panel 100 can be inserted into the width of the third auxiliary plate 300c.

Finally, the anti-bullet panel 100 of the present invention further includes a plurality of first auxiliary plates 300a to third auxiliary plates c positioned between the bullet panel 100 and the bulletproof steel plate to protect the bulletproof steel plate 200 and prevent resonance from occurring even when the power of the live bullet changes, thereby improving durability and reducing resonance.

Meanwhile, as shown in Fig. 14, bulletproof steel plate 200 may be installed at an angle and supported by support bars 400, and bulletproof panels 100 may be installed on the inclined bulletproof steel plate 200.

In addition, as illustrated in Fig. 15, a rubber having a thickness of 9 mm to 11 mm is placed on the back surface of an auxiliary plate 300 formed of an AR500 material steel plate having a thickness of 9 mm to 11 mm, and a rubber having a thickness of 45 mm to 55 mm is placed on the front surface of the auxiliary plate 300, so as to protect the bulletproof steel plate 200 and prevent resonance from occurring even if the power of a live bullet changes.
