  • Publication number: 20020070502
    Abstract: The present disclosure relates to a projectile trap for capturing projectiles emitted along a line substantially parallel to an underlying ground/floor surface. The trap includes a support structure including an inclined support surface that is inclined relative to the line of the projectiles. The inclined support surface includes a front edge positioned generally at the ground/floor surface, and a rear edge oriented at a higher elevation than the front edge. The trap also includes a particulate flowable granular material supported by the support structure. At least a portion of the granulate material is disposed above the inclined support surface such that the inclined support surface is substantially covered with granulate material. The granulate material is adapted for slowing down and capturing the projectiles.

  • Patent number: 5848794
    Abstract: The present invention is a projectile trap assembly for capturing projectiles emitted along a line substantially parallel to ground. The projectile trap assembly includes a support frame having an upper surface inclined relative to the line of the projectiles and a particulate flowable granulate material exhibiting an angle of repose. The particulate granulate material is supported by the support frame at the angle of repose, whereby the particulate granulate material receives and slows down the projectiles.
