Description

  The present invention relates to a moving target device, and more particularly, to a moving target device including a concealable target that moves along a rail laid on a ceiling portion of a shooting range.

  2. Description of the Related Art Conventionally, a target device having a target for hitting a bullet or the like fired by a gunner from a handgun, a rifle, a laser gun, or the like is known in order to improve the accuracy of the gunner's hit. In addition, for the purpose of performing more practical training, various moving target devices that can move the target as well as simply hide the target from the shooter have been developed (for example, Patent Documents 1 and 2). reference).

For example, in Patent Document 2, a shooting training is performed in which a rail is suspended from a ceiling portion of a shooting range, a carriage is moved along the rail by wheels sandwiching the rail, and a target is suspended from the carriage via a target support rod. A device has been proposed, in which the target moves in the front-rear direction when viewed from the shooter, and is concealed according to the rotation of the target support rod.

Japanese Patent Laid-Open No. 9-238797 Japanese Patent No. 3051053

  However, in the apparatus described in Patent Document 2, since the carriage is in a state of being exposed to the shooter, a bullet that is off the target or bounced off by hitting another member hits the carriage. Therefore, in Patent Document 2, it is proposed to install a bulletproof material on the surface of the carriage facing the gunner on the premise that the carriage is hit.

Further, in Patent Document 2, in order to prevent a bullet hitting a carriage or the like from being bounced back toward the shooter, a bullet preventing member such as a rubber plate having a tensile strength of 160 kg · f / cm ² or more is used as a bulletproof material. It has been proposed to use such a rubber plate or the like in combination with a high-tensile fiber member such as a Kepler fiber, a shock absorbing viscoelastic member, a plastic deformation member, or the like.

  However, it is not always possible to reliably prevent the bullets from bouncing back toward the shooter simply by using such bulletproof materials. In addition, even if the bulletproof material and the bulletproof performance improve as the bulletproof material is formed of a highly functional member, the cost of the bulletproof material itself is increased, and the frequency of shots does not decrease. Must be replaced at a certain frequency, which leads to an increase in manufacturing cost and operating cost of the apparatus.

  As described above, as long as it is assumed that the cart or the bulletproof material is hit, it is inevitable that the bulletproof material or the cart itself must be repaired or replaced. In such an apparatus, it is desirable to be configured to actively prevent the bogie from being hit or to reduce the frequency of hitting the bogie.

  Therefore, the present invention provides a moving target device having a concealable target that moves along a rail disposed above a shooter. It is an object of the present invention to provide a moving target device that can prevent rebound.

A concealment drive mechanism for rotating the target around the axis of the shaft;
A cover member that covers the bottom of the carriage from below, has an opening that allows the shaft to move, and is attached to the rail or integrally extended from the rail;
The rail includes a side wall portion at a position outside the carriage,
The cover member is provided so as to be inclined so that the opening portion is lowest,
The cart is characterized in that the bottom portion is formed so as to be inclined substantially parallel to the inclination of the cover member.

  According to the first aspect of the present invention, there is a case in which a bullet fired by a shooter moves toward a carriage traveling on a rail laid on the ceiling portion of the shooting range, for example, by moving off the target. Since it hits the side wall of the cover member or rail that covers the carriage from below, the carriage is protected from being hit, and the frequency with which the carriage is hit is reduced. Further, the cover member is inclined so that the opening provided to allow the movement of the shaft that is suspended from the carriage and the target is attached to the tip is inclined, so that it hits the cover member. Bullets are bounced back in directions other than towards the shooter. Further, since the bottom of the carriage is formed so as to be inclined substantially parallel to the inclination of the cover member, even if the bullet hits the carriage, it is rebounded in a direction other than the direction toward the shooter.

  According to a second aspect of the present invention, in the moving target device according to the first aspect, in addition to the wheel, the carriage includes a wheel that rolls in contact with a side wall portion of the rail.

  According to invention of Claim 2, it is prevented that a trolley | bogie produces position shift in the left-right direction with the wheel which contact | abuts to the side wall part of a rail and rolls.

  According to a third aspect of the present invention, in the moving target device according to the first or second aspect, the surface of the carriage facing the shooter has a direction other than the direction in which the normal direction is directed to the shooter. It is configured to face.

  According to the invention described in claim 3, by configuring the normal direction of the surface facing the shooter of the carriage to be a direction other than the direction toward the shooter, the bullets hitting those surfaces can be obtained. Rebounds in a direction other than the direction toward the shooter.

The invention according to claim 4 is the moving target device according to any one of claims 1 to 3,
The concealment drive mechanism includes a motor device mounted in the carriage so that an output shaft faces downward,

  According to the first aspect of the present invention, even if the bullet flies toward the carriage, the bullet hits the cover member covering the carriage from the lower side or the side wall of the rail. The frequency of performing is reduced. Therefore, the possibility of a failure or the like due to the impact of the cart is reduced, the frequency of repair or replacement of the cart can be reduced, and the maintenance cost of the apparatus can be reduced. Also, bullets that hit the cover member or rail side wall are rebounded in a direction other than the direction toward the gunner, thus preventing bullets that hit the cover member or rail side wall from being rebounded in the direction of the gunner. It is possible to perform shooting training while ensuring the safety of the shooting hand.

  Furthermore, in this way, the frequency of impact on the carriage is greatly reduced, and bullets hitting the rails and carriage are bounced back in directions other than the direction of the shooter, improving the resistance to impact of the carriage itself. Although necessary, as in the above-described conventional example, a high-performance bullet prevention member, a high-tension fiber member, a shock-absorbing viscoelastic member, plastic, etc. for preventing the bullet from bouncing back in the direction of the shooter A There is no need to provide a deformable member or the like, and it is possible to reduce the manufacturing cost of the apparatus.

  In addition, by attaching the cover member to the rail or integrally extending from the rail, the cover member can be easily and reliably disposed so that the bottom portion of the carriage covers from below. Furthermore, the bullet that hits the cover member that is inclined so that the opening portion becomes the lowest is surely rebounded in a direction different from the direction toward the shooter, and the bullet hits the inclined bottom of the carriage. Even in this case, since the bullet is surely bounced back in a direction other than the direction toward the shooter, the above-mentioned effect is exerted accurately, and the bullet that has entered the rail through the opening and has stalled, Since the bullet is guided by the inclination and falls from the opening due to its own weight, the bullet that has entered the rail can be automatically removed from the rail.

  In addition, since the lower wall portion of the cover member and rail is provided so as to be inclined so that the opening portion becomes the lowest, an inward force toward the opening portion is applied to the left and right wheels of the carriage. The position in the left-right direction is always maintained at a position above the opening, and when the carriage moves, it moves smoothly without shaking in the left-right direction. In addition, a rail on which the carriage travels is laid on the ceiling of the shooting range, and the position of the rail is reliably fixed. Therefore, the movement of the target that moves in the front-rear direction along with the movement of the carriage also becomes smooth, the shaking in the left-right direction during the movement is eliminated, and it is possible to prevent the target from shaking in the left-right direction, It is possible to prevent a situation in which the target shakes from side to side and causes unnecessary chaos to the shooter.

  According to the second aspect of the present invention, in addition to the effect of the first aspect of the invention, the carriage is prevented from being displaced in the left-right direction by the wheels rolling against the side wall of the rail. Therefore, it is possible to prevent the trolley from shaking in the left-right direction and to prevent the target from shaking to the left-right direction, causing the target to sway from side to side and causing unnecessary disruption to the shooter. Can be prevented.

  According to the invention described in claim 3, the bullet that has entered from the opening of the cover member may hit the carriage, but the normal direction of the surface facing the shooter of the carriage is in a direction other than the direction toward the shooter. By configuring so as to face, bullets that hit those faces are bounced back in directions other than the direction toward the shooter. For this reason, the effects of the above-described inventions for preventing bullets from being bounced back in the direction of the shooter are more accurately and reliably exhibited.

  According to the invention described in claim 4, in addition to the effects of the inventions described above, the output shaft of a motor device such as a servo motor or a stepping motor mounted downward in the carriage is rotated, and the shaft is interposed via the shaft. By rotating the target around the axis and concealing the target, it becomes possible to perform the concealment operation of the target quickly and accurately.

In the present embodiment, the backstop 8 has a plurality of trap materials 8a made of a flat hard rubber material, steel plate or the like suspended at a predetermined interval, and a box-shaped bullet collection device 8b is provided below the trap material 8a. It is arranged and configured. The backstop 8 collects bullets without damaging them by causing the bullets to be stalled by gradually taking away their kinetic energy while penetrating through a plurality of trap materials 8a and collecting them by the bullet collecting device 8b. is there. For a detailed description of the backstop 8, refer to Japanese Patent Application Laid-Open No. 2006-97932 previously filed by the applicant of the present application.

  Next, the operation of the moving target device 1 according to this embodiment will be described.

  The carriage 4 of the moving target apparatus 1 is pulled by the timing belt 7 a by the rotation of the main pulley of the carriage drive mechanism 7 that operates based on the command of the computer E in the command room D, and is laid on the ceiling S 1 of the shooting range S. The inside of the rail 2 is moved in the X-axis direction shown in FIG.

  At this time, in this embodiment, as shown in FIGS. 5 and 6, the rail 2 is formed in a tubular shape having a substantially pentagonal cross section, and the bottom 4 a of the carriage 4 is inclined substantially parallel to the inclination of the cover member 3. The four wheels 4c of the carriage 4 are configured so as to abut on the lower wall portion 2c of the rail 2 at a substantially right angle.

  With this configuration, as shown in FIG. 7, each wheel 4c of the carriage 4 has not only an upward component (component force) Fz from the lower wall portion 2c of the rail 2 but also an inward component Fy. The force F which has is added. Therefore, it goes without saying that the upward force Fz applied to each wheel 4c prevents the carriage 4 from falling due to its own weight, but the force F applied to each wheel 4c has an inward component Fy. Even if the carriage 4 is displaced in the left-right direction (Y-axis direction), a force to pull back to the center position in the left-right direction of the rail 2 is applied, so the position in the left-right direction of the carriage 4 is maintained at the center position of the rail 2. .

  Therefore, in this embodiment, the cart 4 moves smoothly without shaking in the left-right direction when moving in the front-rear direction. In addition, the movement of the target 6 that moves in the front-rear direction along with the movement of the carriage 4 becomes smooth, and there is no left-right shaking during the movement. Disappears.

  As shown in FIGS. 4 (A) and 4 (B), when the rail 2 has a substantially rectangular cross section, a force having only an upward component is applied to each wheel 4c of the carriage 4. Therefore, in such a case, as shown in FIG. 8, the cart 4 is provided with auxiliary wheels 4k that contact the side wall 2b of the rail 2 in addition to the wheels 4c that contact the lower wall 2c of the rail 2. If it comprises, it becomes possible to prevent the shaking to the left-right direction in the case of the movement of the trolley | bogie 4. FIG.

  On the other hand, the concealment drive mechanism 4h of the carriage 4 rotates the motor device 4i by a predetermined angle on the basis of a command from the computer E in the command room D received through a trolley duct installed in the rail 2, thereby causing the shaft 5 to move. The target 6 attached to the tip thereof is concealed from the shooter A by rotating around the axis. The concealment of the target 6 may be performed during the movement of the cart 4 in the front-rear direction, or may be performed while the cart 4 is stopped.

  Further, as described above, if the motor device 4i of the concealment drive mechanism 4h is configured by a servo motor, a stepping motor or the like, the concealment operation of the target 6 via the shaft 5 can be performed quickly and accurately. Become.

  The shooter A thus moves in the front-rear direction as the carriage 4 moves in the front-rear direction, and fires and shoots a bullet toward the target 6 that is concealed by being driven by the concealment drive mechanism 4 h. Provide training.

  At that time, the fired bullet may deviate from the target 6 or hit the other member such as the fixing member 5a to be bounced back and head toward the carriage 4 in some cases. However, in the present embodiment, as shown in FIGS. 3 and 4, the carriage 4 has a lower wall portion 2 c of the rail 2 and a cover member 3 that is integrally extended from or attached to the rail 2 from the lower side. Since it is covered and the side wall 4b is covered with the side wall 2b of the rail 2, the bullet hits the cover member 3, the side wall 2b of the rail 2, and the like. Therefore, the cart 4 is protected from being hit.

  Further, as shown in FIG. 9, the cover member 3, the lower wall portion 2 c of the rail 2, the side wall portion 2 b, and the like each extend in the X-axis direction, that is, the front-rear direction, and the normal direction thereof is the direction toward the gunner A Turn in the other direction. Therefore, the bullet F hitting them is not rebounded in the direction of the shooter A, but is rebounded to the back stop 8 side at the innermost side of the shooting range S shown in FIG. In this way, in this embodiment, the cover member 3 and the like are prevented from being hit by the carriage 4, and the bullet F is rebounded away from the shooter A, thereby moving the bullet F toward the shooter A. Bounce is prevented.

  In FIG. 9 and FIG. 5 described above, the left end portion of the rail 2 in the drawing is expressed as being open, but actually, as shown in FIG. Is sealed by a cart drive mechanism 7 provided with a main pulley, etc., and bullets do not enter the inside of the rail 2 through the opening.

  However, as described above, the cover member 3 provided on the lower wall 2c of the rail 2 is provided with the opening 3a that allows the shaft 5 to move, and the bullet enters the rail 2 from the opening 3a. There is a case.

  A bullet that has entered the inside of the rail 2 is bounced back by the upper wall 2a of the rail 2 shown in FIG. 3 or the like and advances out of the rail 2 from the opening 3a, or the upper wall 2a or side wall of the rail 2 2b, the lower wall 2c, the cover member 3 and the like are collided and bounced back, so that kinetic energy is lost and the rail 2 is stalled.

  In the present embodiment, since the lower wall portion 2c of the rail 2 and the cover member 3 are provided so as to be inclined with respect to the horizontal plane so that the opening 3a of the cover member 3 is the lowest, the bullets are formed in the rail 2. When stalled, the bullet is guided in the direction of the opening 3a of the cover member 3 by its own weight, falls from the opening 3a, and is automatically removed from the inside of the rail 2.

  In addition, a bullet that has entered from the opening 3 a may directly hit the carriage 4. In this case, as shown in FIG. 5 and the like, the bottom portion 4a of the carriage 4 is inclined substantially parallel to the inclination of the cover member 3 so as to have a substantially V-shaped cross section, and the front portion of the carriage 4 protrudes forward. If the bottom 4a of the carriage 4 and the four surfaces 4d to 4g are all configured to face directions other than the direction toward the gunner A, as shown in FIG. As shown, even if the bullet F enters from the opening 3 a of the cover member 3 and hits the carriage 4, the bullet F is in a direction other than the direction toward the gunner A at the inclined bottom 4 a or front surfaces 4 d to 4 g of the carriage 4. Therefore, it is possible to prevent the bullet F from bouncing back toward the shooter A.

  As described above, according to the moving target device 1 according to the present embodiment, the bottom 4a of the carriage 4 traveling on the lower wall 2c of the rail 2 laid on the ceiling S1 of the shooting range S is By covering from the lower side with the cover member 3 attached to the lower wall part 2c or extending integrally from the lower wall part 2c, and further covering the side wall 4b of the carriage 4 with the side wall part 2b of the rail 2. It is possible to reduce the frequency with which the carriage 4 is hit by the bullets fired by the shooter A. Therefore, the possibility that a failure or the like will occur due to the impact of the carriage 4 can be reduced, the frequency of repair or replacement of the carriage 4 can be reduced, and the maintenance cost of the apparatus can be reduced.

  Further, the bottom 4a of the carriage 4 is covered with the cover member 3 or the like from the lower side, and the side wall 4b of the carriage 4 is covered with the side wall 2b of the rail 2, so that the cover member 3 or the side wall 2b of the rail 2 is provided. It is possible to prevent the bullets that hit the shooter A from bouncing back in the direction of the shooter A, and it is possible to perform shooting training while preventing the bullet from bouncing back to the shooter side and aiming at the safety of the shooter. .

  Further, as described above, the frequency of impact on the carriage 4 is remarkably reduced, and bullets hitting the rail 2, the carriage 4, etc. are rebounded in directions other than the direction of the shooter A. Even if it is necessary to improve the resistance to impact, etc., as in the conventional example described above, a high-performance bullet prevention member or high-tensile fiber member for preventing the bullet from bouncing back in the direction of the shooter A, shock absorption There is no need to provide a viscoelastic member, a plastic deformation member, or the like.

  As described above, in the moving target device 1 according to the present embodiment, since the frequency of hitting the carriage 4 is significantly reduced, the cost of repairing and replacing the carriage 4 and the like can be reduced, and the structure of the bullet can be reduced. Since rebounding in the direction of the shooter A can be prevented, the manufacturing cost and operating cost of the apparatus can be reduced.

  Further, the cover member 3 is attached to the rail 2 or formed integrally with the rail 2 so that the cover member 3 is easily and surely disposed so that the bottom portion 4a of the carriage 4 covers from below. Is possible. Furthermore, the bullet that hits the cover member 3 that is provided so as to be inclined so that the opening 3a is the lowest is surely rebounded in a direction different from the direction toward the shooter A, and the bullet is inclined to the carriage 4. Even when it hits the bottom part 4a, the bullet is surely bounced back in a direction other than the direction toward the shooter A, so that the above-mentioned effect can be exerted accurately, and it enters the rail 2 through the opening 3a. The stalled bullet is guided by the inclination of the cover member 3 and falls from the opening 3a due to its own weight, so that the bullet that has entered the rail 2 can be automatically excluded from the rail 2.

  Further, by providing the cover member 3 and the lower wall portion 2c of the rail 2 with an inclination so that the opening portion 3a is the lowest, an inward force toward the opening portion 3a is exerted on the left and right wheels 4c of the carriage 4. Therefore, the position of the cart 4 in the left-right direction is always maintained at the position above the opening 3a, and when the cart 4 moves, it moves smoothly without shaking in the left-right direction. . Further, the rail 2 on which the carriage 4 travels is laid on the ceiling portion S1 of the shooting range S, and the position of the rail 2 is reliably fixed. Therefore, the movement of the target 6 that moves in the front-rear direction along with the movement of the carriage 4 also becomes smooth, and there is no shaking in the left-right direction during the movement, and the occurrence of the shaking of the target 6 in the left-right direction can be prevented. It becomes possible, and it becomes possible to prevent the situation where the target 6 shakes to the left and right and causes the shooter A to be unnecessarily confused.

  In the present embodiment, as shown in FIGS. 3 and 4 and the like, the case where the rail 2 includes the upper wall portion 2a has been described. However, the upper wall portion 2a is not necessarily provided. In this case, for example, as shown in FIGS. 11A and 11B, the rail 2 can be formed by two H-shaped steels 20 arranged in parallel and a member 21 having a substantially U-shaped cross section. is there. I-shaped steel, L-shaped steel or the like may be used. In this case, although not shown in the figure, the carriage causes the wheels to abut on the lower flanges 20a and 21a of the H-section steel 20 and the member 21, and if necessary, auxiliary wheels are provided to the webs 20b and 21b.
