Plastic slide for sleds

Image Number 4 for United States Patent #4484739.

A slide structure for sleds for human occupancy is disclosed, and is designed to have human occupant sleds sliding down into a body of water. The slide structure has a support framework on which a plastic sheet material is provided and a water supply means supplies only a thin film of water to the upper surface of the plastic sheet material. This conserves power and water, yet the thin film provides a very low coefficient of friction, so that the sleds attain a high speed for a quiet, fast, smooth, and more exciting ride, yet with reduced wear on both the slide and sleds.
