  • Publication number: 20030196308
    Abstract: A grind rail and transport kit provides a conveniently portable and durable grind rail. In use, the grind rail has stands that support a grind beam, thereby providing a stable riding surface. The assembled grind rail is of sufficient height, length, and stability to provide a safe and stable riding experience. To facilitate portability, the grind rail disassembles into rail pieces and stand pieces. The rail pieces and stand pieces cooperate to form a stable transportable assembly. The transportable assembly is about one-half the length of the grind rail, and is about as wide as the grind beam.

  • Publication number: 20030176226
    Abstract: A launch ramp provides a conveniently portable and durable launch ramp. The launch ramp has a metal riding-plate with a concave radius-riding surface. The riding-plate has an approach end where a skateboarder enters the ramp and a launch end where the skater propels off the ramp. The riding-plate has integrally formed supports for providing sufficient support, but yet retains desirable flex in the riding surface. A stand-plate elevates the approach end at a predetermined height. The stand-plate also has integral stand-plate supports for added stability and durability. In a preferred example of the launch ramp, the launch ramp is constructed from a single sheet of aluminum-magnesium stock plate. A die press or other bending mechanism forms the single sheet into a particularly durable and stable structure.
