JP5331185B2 - Backstop - Google Patents

Description

  The present invention relates to a backstop (stopping device), and prevents a bullet that has been fired by a shooter and removed a target or a bullet that has penetrated the target from being scattered in a shooting range for performing actual shooting. Therefore, it is usually a backstop for catching bullets behind the target.

  Conventionally, a plurality of technologies related to backstop have been disclosed. As an example, the invention is an invention configured to capture and easily collect bullets without crushing them. For example, as in Patent Document 1.

  In this technique, however, the backstop is disposed behind the target. The backstop (1) includes a trap material (21) and a trap material (21) made of a hard rubber material containing fibers. A plurality of suspensions are provided, and a steel plate (3) is provided behind the trap material, or a trap material (21) made of hard rubber material containing fibers and a trap material (22) made of steel plate are alternately provided Is disclosed, and its purpose and effect are to prevent damage to the shot bullet and to reliably collect the bullet.

  However, this technology is simply arranged so that the interval of the trap material is larger than the length of the bullet, but the target position is determined at the actual shooting range, and the landing distribution is mostly in the center of the target, Only one portion of the trap material is subjected to concentrated hitting, and a missing portion is generated in only one minute.

  The trap material in which the missing part is generated only in this one part is wasteful because it is necessary to replace the trap material with a new one because the effect of stopping the bullet in one part is lowered.

  Next, as a second example, a backstop (1) is also provided behind the target (20), and a bullet is fired toward the incident target part (22) of the target (20), so that the target part The bullet passing through (22) is constructed so that the bullet is collected by the back strap (1), and the bullet is easy to collect, economical, small and easy to install. . For example, as in Patent Document 2.

  In this disclosed technique, the part where the bullets are concentrated and incident can be separated from the other part and exchanged, and the hole part corresponding to the target target part of the target provided on the plate (4) In addition, the hole (9) is provided with a replacement part (10) to be detachably mounted, and the hole (9) of the replacement part has a circular peripheral surface in the circumferential direction. Three recessed portions (8) are formed.

  However, there are many cases where the peripheral surface of the hole (9) is hit by the shooting, and it is impossible to reliably replace the replacement portion (10) of the target (20) using this peripheral surface.
