  • Patent number: 6293552
    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.
