20130175774 | Skateboard truck and caster with suspension mechanism - The present invention relates generally to skateboard and caster devices. More particularly, in a manner the invention concerns both dual wheel and single wheel axle supports of trucks and casters having a suspension mechanism for absorbing shock. The suspension mechanism is uniquely designed to progressively increase suspension resistance as forces acting on the mechanism increase by elastically deforming an independent arm in a manner to contact another arm or structure thereby transforming the independent arm into a dependent arm that results in a progressive resistance to a load until the forces are terminally engaged into a resilient abutment. A novel alignment mechanism functions to maintain the skateboard steering function. | 07-11-2013 |
20140027989 | Skateboard Truck - A skateboard truck maintains truck geometry.

A support pin bushing under the cylindrical end is compressible and both carries some of a rider's weight and holds the ball end in the socket providing a second pivot to the truck. The second pivot eliminates horizontal play of the hanger thereby facilitating consistent compression of the kingpin bushings and improved stability of the skateboard. Support pin travel allows off-center kingpin bushing compression for steering and improves shock absorption. Eliminating horizontal play allows lengthened kingpin bushings and use of the entire height of the kingpin bushings. The combination of kingpin bushing preload, and weight carried by the support pin, tends to equalize the compression of the top and bottom kingpin bushings improving stability. | 01-30-2014 |
