The present invention relates to a device for stopping and collecting a shot shot from a firearm, and a method for collecting a shot by the device.

Background art

In shooting competitions such as ski dredge shooting and trap shooting, shots containing shots are used. The above-mentioned ammunition contains approximately 400-65 mm lead-made shots with a diameter of 2-2.5 mm. After shooting, these shots are scattered into smaller particles. It is difficult to collect all the shots that have been collected. In addition, when a lead shot collides with a target (clay) or the ground, lead dust may be generated due to the impact. This lead dust remains in the shooting range and is easily scattered when external force is applied. . For this reason, environmental pollution due to lead remaining in shooting ranges, etc., and the safety of work when removing lead shots are problems.

JP-A20 0 2— 6 2 0 95 includes a frame, a surface layer covering the frame, and a stop layer filled with a chip-like elastic member that is filled inside the surface layer and is removable. A bullet device is disclosed. This device decelerates, stops, and captures bullets in the packed bed. The packed bed uses rubber powdered into an irregular shape with an outer diameter of 1.0 to 30 mm.

In addition, the present invention is an application for stopping and collecting a shot of an apparatus having one or two or more decelerating means supported and suspended, and a plate. Brief Description of Drawings

Fig. 1 is an illustration of how to use a shotstop and recovery device. Detailed Description of the Invention

The present invention relates to a shot stopping and collecting device that can easily collect shots shot at a shooting range and the like, and a shot stopping and collecting method using the device. The shot shots (lead shots) fired from the firearms are significantly decelerated by impacting (landing) and penetrating the decelerating means, eventually colliding with the plate and falling. I will give you. Since the fallen lead shot remains in a narrow area, it can be easily recovered by suctioning it with a vacuum cleaner. In addition, the decelerating means also acts to capture and drop the woods and target debris other than lead shots during loading.

The size of the decelerating means should be adjusted to ensure that all shots land on the decelerating means according to the distance from the shooter position to the target (decelerator).

The number of speed reducers increases or decreases according to the distance from the shooter position to the target (speed reducer). For example, the optimum number of deceleration units can be determined by performing a real-fire test in advance, but in that case, by using an excessive number of deceleration units in advance, the optimum number can be obtained by gradually reducing the number. It is possible to prevent the scattering of lead shots even during the real test.

When a plurality of speed reduction means are used, they may be placed in contact with each other. However, from the viewpoint of increasing the speed reduction effect and reducing the number of speed reduction means, the spacing between the speed reduction means It is preferable to arrange in a state where The decelerating means is based on the premise that lead shots penetrate, and the plate accepts lead shots without penetrating them. Therefore, the material corresponding to each action is selected. You can use more than one plate, and in such a case, the shot may penetrate the first plate, but it does not have to penetrate the final plate. In addition, the plate may be a composite in which two or more different materials are combined and integrated, or a plurality of two or more different materials may be used.

The plate is preferably made of synthetic resin from the standpoint of reducing the weight of the stopping and collecting device and making it easy to carry. Wood is preferable from the viewpoint of preventing the generation of lead dust by trapping the shot. . The synthetic resin plate has excellent impact resistance, heat resistance, and weather resistance, as well as elasticity and viscosity. Polycarbonate, polyamide, polyacetal, etc. are preferred because they are difficult to deform and difficult to break, but other thermoplastic resins and thermosetting resins may be used. The thickness of the plate can be adjusted to a thickness that prevents the shot from penetrating depending on the material. For polycarbonate, the thickness is 0.5 to 1 O mm, preferably 1 to 3 mm. One plate or two or more plates can be used.

The plate may be a single plate as a whole, or it may be a single plate made by combining multiple small plate pieces. For example, prepare a multi-divided frame (for example, a 9-divided frame. The size of each frame may be the same or different), and you can detach all nine plate pieces there. Install so that it becomes. In this way, even if a shot is repeatedly impacted and the plate is damaged, only the severely damaged plate piece needs to be replaced, so that maintenance costs can be reduced and wasteful use of resources can be prevented. The frame can be made of the same material as the plate.

The method of supporting and hanging the speed reduction means and the method of supporting the plate are not particularly limited. For example, prepare a frame member (side shape is inverted L-shaped) that has two struts and two arms (extending parallel to the installation surface) that extend from the two struts at right angles. Then, fix the two struts to the ground or floor (you can fix them with casters if necessary, and you can make them moveable), and the required number of pieces to straddle the two arms Supports the speed-reducing means of the vehicle.

Further, according to the present invention, the speed reduction means is a sheet-like material made of a material selected from thermoplastic resin, natural or synthetic rubber, natural or synthetic fiber, paper, non-woven fabric, and a composite thereof. And a recovery device.

The thickness and number of sheets that serve as the speed reduction means depend on the material and the position of the shooter. It can be determined in relation to the deceleration effect required according to the distance to the speed device. For example, when the thickness is increased, the number of sheets is decreased. On the other hand, when the thickness is decreased, the number of sheets is increased so that a desired deceleration effect can be obtained. In addition, from the viewpoint of enhancing the deceleration effect, an adhesive substance layer can be provided on the surface of the sheet serving as a deceleration means.

As an example of the thickness and the number of sheets, it is preferable to use 2 to 5 sheets of thermoplastic resin sheets having a thickness of 0.5 to 10 mm, preferably 1 to 3 mm. As the thermoplastic resin sheet, those having good flexibility are preferable, and examples thereof include polyethylene, polypropylene, polystyrene, polyvinyl chloride, and polyester. By using such a thermoplastic resin, it is preferable that it melts with the heat when the shot penetrates, so that the speed reduction effect is enhanced.

The speed reducing means may be a resin sheet in which no holes are observed by visual observation, but the fiber is formed by folding the fibers like a woven fabric made by weaving natural or synthetic fibers, and is extremely small by visual inspection. Those in which pores are observed are preferred. Such a woven fabric has a better effect of restoring the through-hole portion when a shot penetrates than a sheet, so the number of times it can be used becomes longer and the maintenance cost can be reduced.

Furthermore, the present invention preferably relates to a shot stopping and collecting device, wherein the speed reducing means is a rectangular sheet-like shape and is suspended while being partially supported.

When the speed reducing means is a rectangular sheet, it can be suspended while supporting one short side or long side, or two corners on each side.

Furthermore, the present invention preferably relates to a shot-stopping and collecting device in which two or more of the speed reduction means are suspended at intervals, and the target is drawn on the first speed reduction means. The target may be provided separately from the stopping and collecting device, but providing a target for the stopping and collecting device eliminates the need for a separate target.

The interval when using a plurality of speed reduction means is preferably 1 to 100 cm, more preferably 10 to 30 cm, in order to enhance the speed reduction effect and not to increase the stopping and recovery device itself. .

Furthermore, the present invention preferably relates to a method of collecting the shotlet that has been fired from a firearm toward the stoppage and recovery device by disposing the above-mentioned shotstop and recovery device outdoors or indoors.

The stopping and collecting device of the present invention can be used not only outdoors but also indoors as in the past. When used indoors, the floor surface is concrete, etc., so that it is easier to collect shots compared to the ground like outdoors, as well as the advantage of reducing the shooting sound on the surroundings. is there.

According to the shot stopping and collecting apparatus of the present invention, it is easy to collect lead shots, and the generation of lead dust can be prevented, so that adverse effects on the environment can be greatly reduced. Furthermore, by using the shot stopping and collecting device of the present invention, it becomes possible to hold indoor shooting competitions, which can contribute to the spread of shooting competitions.

BEST MODE FOR CARRYING OUT THE INVENTION

Suspension and recovery equipment for grenades>

Hereinafter, the embodiment will be described with reference to FIG. FIG. 1 is an explanatory view of a method of using the stopping and collecting device of the present invention.

The shot-stopping and collecting device 10 is composed of a combination of a frame 1 and sheeters 2 1 to 2 3 serving as deceleration means and plates 3 1 and 3 2. The sheets 21 to 23 are made of woven fabric made of natural or synthetic fibers. By using a woven fabric, the weight can be reduced compared to a resin sheet of the same thickness. The restoring action of the through hole when the shot penetrates is superior to a simple resin sheet.

The frame 1 1 has two struts 1 2 and 1 3 and two arms 14 and 1 5 that extend from the struts 1 2 and 1 3 at a right angle or an approximate angle. The base parts 1 6 and 1 7 of the book posts 1 2 and 1 3 are fixed to the ground using concrete or the like.

The height of the struts 1 2 and 1 3 is determined in relation to the height of the target.If necessary, the height of the struts can be extended and detachable by combining multiple struts. It may be possible to set the height of the support from the desired range.

The lengths of the arms 14 and 15 are determined according to the number of sheets 2 1 to 2 3 to be suspended and the interval between them. In order to be able to adjust the number of decelerating means according to various demands at the shooting range etc., the arms 1 4 and 1 5 can be extended and retracted, or they can be attached to and detached from the columns 1 2 and 1 3 themselves. it can. On the arms 14 and 15, three sheets 2 1 to 2 3 are suspended with their sections supported. The method for supporting the seats 2 1 to 2 3 on the arms 14 and 15 is not particularly limited, and the method is to clamp the seat at two points with the clamps provided on the arms 14 and 15, For example, a method of hooking holes provided in the two corners of the sheath can be applied to the hooks provided on the arms 14 and 15.

The first sheet 21 is the first deceleration means that lands first. The second sheet 22 is a second reduction means that lands after the first sheet 21, and the third sheet 23 is a third reduction means that lands after the second sheet 22. The intervals between the sheets 2 1 to 2 3 are the same and are adjusted to be in the range of 10 to 30 cm.

Sheets 2 1 to 23 have a thickness of 1 to 3 mm, a short side of 1 to 3 mm, and a long side; ~ Five It is a rectangular sheet of mm, and is a thermoplastic resin sheet selected from polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyester and the like. The thickness may be varied for each resin sheet within the thickness range.

In the case where a plurality of shooters shoot in a wide place, a long sheet can be developed and used instead of the sheets 21 to 23 as shown. The width and length of the long sheet can be appropriately selected depending on the situation. For example, a sheet having a width of 1 to 5 mm and a length of 50 to 10 Om can be used.

The first plate 31 acts to further decelerate the shot that has penetrated the third sheet 23, or to prevent further penetration and to receive and drop the shot. is there. The second plate 32 acts so that when the shot penetrates the first plate 31, it prevents further penetration, receives the shot, and drops it. Here, shot 1 is used as the first plate 31: P: Use a non-penetrating plate, and if it is necessary to ensure safety (for example, when required in shooting competitions), the second plate 3 2 May be arranged.

The first plate 3 1 and the second plate 3 2 have a rectangular shape with a short side of 0.5 to 3 m and a long side of 1 to 5 m made of a material selected from poly force, polyamide, polyacetal, wood, etc. belongs to. The thicknesses of the first plate 3 1 and the second plate 3 2 can be appropriately set depending on the material. For example, in the case of a polycarbonate cage, the thickness is preferably 1 to 3 mm.

The first plate 31 and the second plate 32 may be made of different materials, and the first plate 31 can be made of wood and the second plate 32 can be made of polycarbonate. By using such a combination, the lead shot is sunk into the first plate 3 1 made of wood and collected. When passing through the first plate 31, it can be reliably received by the second plate 32 made of polycarbonate. When a long sheet is used, a long plate may be used or a plurality of plates may be combined and arranged according to the sheet shape.

In the stopping and collecting apparatus 10 of the present invention, the sheets 2 1 to 2 3 are replaced every time one or more times are used depending on the degree of damage. At this time, the replacement times of the sheets 21 to 23 may be the same or different. In addition, plates 3 1 and 3 2 can be replaced by multiple use depending on the degree of damage. The replacement times of the plates 3 1 and 3 2 may be the same or different.

In the stopping and collecting apparatus 10 of the present invention, the sheet 2 1 to 2 3, the plate 3 1, 3 2 or the sheet 2 1 to 2 3 and the plate 3 1, 3 2 are each combined as one set, Each combination may be supported by a single support member so that they can be exchanged together as a set.

How to collect gushshots>

Next, the method for collecting shots of the present invention will be described with reference to FIG.

First, a shotstop and recovery device 10 is installed in a shooting range such as a shooting range. Conditions such as the number of sheets 2 1 to 2 3 and plates 3 1 and 3 2, thickness, etc. are as follows: Shooting position of shooter 40 and shot speed (usually about 50 O m / s) and landing Considering the speed of the air (usually about 300 mZ s), it is set so that the shot can be captured and recovered reliably.

Shooter 40 fires shotgun 41 from a predetermined shooting position (the shooting position is determined by the type of competition). 2 4 indicates the state of the shot after firing. In the case of clay shooting, it hits the clay at the position of 24, for example. The fired shot lands on the first sheet 21 as the first deceleration means (2 5 indicates the state where the shot has landed), penetrates while being decelerated, and in the same way, the second sheet 2 2 and 3rd sheet 23. At this time, since the sheets are suspended at intervals, the landing effect of the first sheet 21 is increased by swinging toward the second resin sheet 22, and so on. 2 2 swings toward the third sheet 2 3 to increase the deceleration effect, and the third sheet 2 3 swings toward the first plate 3 1 to increase the deceleration effect.

The shot that has penetrated through the third sheet 23 is landed on the first plate 31 and partly penetrates after being further decelerated, or falls without penetrating all. When the first plate 3 1 catches the shot, the immediately preceding third sheet 2 3 prevents the scattering of the shot that bounces back after the first play 卜 3 1 (occurrence of a jump) and promotes the fall. Acts like

If the shot passes through the first plate 31, it lands on the second plate 3 2, is received and falls. When the second plate 3 2 catches the shot, the first plate 3 1 immediately before the second plate 3 2 prevents the splash of the shot that bounces off after the collision (occurrence of a jump) and promotes the fall. It works as follows.

The shots received and dropped by the first plate 3 1 or the second plate 3 2 are scattered just below the stopping and collecting device, so they can be easily sucked with a vacuum cleaner. It can be recovered.

The present invention includes the following aspects. Provide a stopping and recovery device that facilitates the collection of shots. The shots fired by the shooter 40 penetrate through the first resin sheet 21, the second resin sheet 22, and the third resin sheet 23 while being decelerated, and are received by the first plate 31 and the second plate 32. Drops under collection device 10. Falling shots have a small splash range, so they can be easily recovered. wear. Example
