Abstract
A modular ramp system contemplates two molded plastic ramps placed back-to-back with one another so that in a direction of travel, one would travel up one ramp and then immediately down the other. The ramps are interconnected by a spine including connectors interfacing with connectors provided on the facing surfaces of the ramps. In the preferred embodiment, the connectors consist of dovetail recesses and dovetail projections. The ramps also have connection structure on their lateral sides, so that other ramps may be assembled to the two back-to-back ramps to make a ramp that is incrementally wider. The ramp may consist of a plurality of ramp sections assembled together to create a ramp. A table is designed to be used with ramps and other components and includes openings to facilitate installation of a grind rail or a support rail. The table surface includes peripheral coping integrally formed with the table during manufacture. A grind rail system includes support legs with arcuate bottoms to facilitate safe support of a grind rail regardless of angulation. Curved sections of grind rails allow lateral and vertical curvature of an elongated grind rail configuration. Connectors are p…
