  • Simplified steering mechanism for skateboards and the like
    Patent number: 5330214
    Abstract: A novel, simplified steering mechanism is provided which has both wheel tilting and steering capabilities. The steering mechanism comprises generally a platform, an angled plunger, top and bottom axles of equal length, and a pair of wheels. When a downward vertical force is applied to a side of the platform, the platform and plunger tilt towards that force, thereby causing tilting and directional changes in the wheels. The axles are of such a length that the platform and wheels cannot come into contact with each other, even upon exertion of a downward vertical force.
