US Patent:

52322351, Aug 3, 1993

Filed:

Dec 8, 1992

Appl. No.:

7/988868

Inventors:

Paul F. Brooks - Sandy UT

International Classification:

A63C 1701

US Classification:

280 87042

Abstract:

A novel skateboard steering mechanism is provided which has both wheel tilting and steering capabilities. The steering mechanism comprises generally a platform, a plunger which is fixedly attached at one end of the bottom face of the platform, top and bottom axles of equal length disposed in parallel aligned space relationship to each other, a pair of wheels, and a steering assembly. Advantageously, the plunger encases the entire steering assembly and holds it within a set position. The steering assembly comprises upper and lower balls rigidly affixed to the top and bottom axles, respectively, at approximately the mid points thereof, a floating cam disposed between the upper and lower balls, and a wire spring, or similar, biasing the floating cam in a set position.

International Classification:

A63C 1701

US Classification:

280 87042

Abstract:

A novel steering mechanism is provided which has both wheel tilting and steering capabilities. The steering mechanism comprises generally a platform, a plunger which is fixedly attached at one end to the bottom face of the platform, top and bottom axles of equal length disposed in parallel aligned space relationship to each other, a pair of wheels, and a steering rod. The plunger hingedly intersects each axle. The top axle includes a forwardly extending steering rod holder and the bottom axle includes a rearwardly extending steering rod holder, the steering rod holders being in axial alignment with each other. One end of both the top and bottom axles are hingedly connected to one wheel while the other end of both axles are hingedly connected to the second wheel. A steering rod intersects both steering rod holders and the plunger in axially sliding relationship, such that when a downward vertical force is applied offset from the center of mass of the platform, the platform and plunger change position to a) bring the top and bottom axles out of alignment to cause the wheels to tilt, and b) bring the forwardly and rearwardly extending steering rod holders out of alignment to cause the platform to turn relative to the axles and wheels.

Kenneth D. Lisonbee - West Jordan UT

International Classification:

A63C 1701

US Classification:

280 87042

Abstract:

A simplified steering mechanism having both wheel steering and wheel tilting capabilities is provided. The mechanism comprises a generally planar platform, a plunger assembly attached to the bottom face of the platform, top and bottom axles of equal length, and a pair of wheels. Each axle intersects an intermediate space in the plunger assembly at an approximate midpoint, the ends of the axles being pivotally attached to the wheels when a downward vertical force is exerted on one of the longitudinal sides of the platform, the wheels tilt and turn simultaneously relative to the platform.

International Classification:

A63C 1701

US Classification:

280 87042

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.
