  • 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: 6000700
    Abstract: A projectile trap assembly for capturing projectiles emitted along a line substantially parallel to a ground surface includes a support frame generally inclined relative to the line of the projectiles; a primary volume of particulate material disposed on the support frame for slowing down and capturing the projectiles, the primary volume including a target region in which a majority of the projectiles are captured; and the support frame having a trap door positioned proximate the target region, the trap door being arranged and configured to allow a portion of the primary volume of particulate material coinciding generally with the target region to be removed from the trap assembly through the support frame.

  • 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.

  • Patent number: 5607163
    Abstract: A range backstop assembly including a container having a plurality of sides. At least two of the sides have openings typically closed by a rubber sheet and serving for projectile entry. The container is filled with a particulate flowable granulate material which slows down the entering projectiles. The range backstop also includes a structure for facilitating movement of the backstop.

  • Patent number: 5435571
    Abstract: A range backstop assembly having a container with an opening typically closed by a rubber sheet and serving for projectile entry. The container is filled with a particulate flowable granulate material which slows down the entering projectiles. An anti-adhesion medium is further interspersed between the particles of the granulate material to prevent adhesion of the granulate material in the presence of heat generated by the entering projectiles.
