  • Patent number: 8302977
    Abstract: A Flexible Skateboard Truck intended to provide improved shock absorption and maneuverability consists of a monocoque and an axle whereby a connection is made between a mass and a device capable of moving across a surface. Said monocoque consists of flexible material which can be repeatedly deformed and returned to its original, constructed shape. Applied pressure and shock is absorbed and momentarily stored as energy by said monocoque whose instantaneous, controlled release by the rider steers said Flexible Skateboard Truck. The mounting points are configured to allow for stability and flexibility. Additional compressive support can be introduced by the insertion of a pneumatic bladder or bladders. An optional slit or slits and rib or ribs can be introduced in order to facilitate steering.

  • Patent number: 7837209
    Abstract: A person rides the Tri-Axial Control Device standing on pedal assemblies. The pedal assemblies are attached to a control axial member thus forming the Tri-Axial Control Device. The control axial member on the vertical stick, can rotate fore and aft, and turns the front skis and/or wheels. Changing the angle of the vertical stick side-to-side changes the pedal angle. If the rider falls forward the front stick can rotate away. Various torsion controls rod assemblies and pedal assemblies can be utilized to create a unique tri axial device. The device can be folded, is lightweight and can be manufactured without welding. No special equipment or training is required to operate the device. In addition to its entertainment uses, the mounting device for portable electronics can also be used for added safety by adding a global positioning system or other electronic signal device, allowing safety personnel to locate the rider.
