Abstract
A method and apparatus for a pneumatically sprung caster mechanism to provide a pneumatically controlled ride height for a platform attached to the caster. The caster is mounted to a first end of a pivoting axle, while a piston is mounted to the opposite end of the pivoting axle. The length of the piston is pneumatically controlled to rotate the pivoting axle to either increase, or decrease, the distance between the caster and the platform. Suspension is provided through interaction of the piston with an air reservoir, whereby minute variations in the length of the piston are absorbed by the elasticity of the walls of the air reservoir. A free-flow of air is facilitated such that air forced out of the piston during contraction may be collected by the air reservoir and air required by the piston during expansion may be provided by the air reservoir.
