US 6,318,739 B1 · Suspension for a skateboard

Abstract

A suspension assembly for a skateboard is disclosed having a base plate with a truck plate pivotally attached at one end. A shock absorber is located between the base plate and the truck plate. A projection on the base plate protects the shock absorber and aids the rider in performing tricks. In use, a wheel truck is attached to the truck plate opposite the shock absorber. The suspension assembly provides a suspension for a skateboard which helps to protect the rider from bumps, while retaining good steering control. In another embodiment of the invention, the suspension assembly includes a base plate with a projection at each end. Each projection has a groove and a top out stop. A truck plate is biased away from the base plate by a shock absorber, with the ends of the truck plate sliding in the grooves. Also part of the invention is a skateboard incorporating a pair of suspension assemblies.
