Patent number: 11452930Abstract: A steering system for a snowboard includes two binding interface pods, one of which may be active and one of which may be passive. Rotation or tilting of a top plate of the active binding interface pod in response to rotation or tilting of the rider's steering foot causes counter-rotation of a steering fin under the rider's steering foot. The passive binding interface pod is responsive via a linkage between the active and passive binding interface pods to cause rotation of a steering fin under the rider's non-steering foot. Coordinated counter-rotation of the steering fins causes the board to turn in the direction of rotation of the rider's steering foot when the steering fins are unaligned. Optionally, both binding pods may be active in steering, i.e. enabling two footed steering.Type: GrantFiled: May 18, 2021Date of Patent: September 27, 2022Inventor: Brian Carr

Patent number: 9975035Abstract: A bifurcated spring-tethered electric skateboard is bifurcated into a front deck and rear deck with each deck having independently powered wheels. The skateboard has a mounted power source, generating electrical power for a motor that is transmitted to the wheels. A controller is configured to control the speed of the motor, and the wheels. The controller is electrically connected to the motor for direct control, or a wireless transmitter for remote control. A spring assembly connects the decks, creating a spring-tensioned effect between the decks while riding the skateboard. The uneven ride requires that the trucks do not rotate fully. A cable that connects the electrical components can also be damaged from excessive rotation of the trucks.

Patent number: 9550107Abstract: An apparatus for sliding/gliding on a surface includes a long board and a short board connected to the long board through a hitch beam. The short board is connected to the hitch beam through an axle placed at an angle on the short board, and the long board is connected to the hitch beam through a stationary, non-rotating connection. A turn plate on the long board is connected to the short board so that as the turn plate rotates relative to the long board, the short board can be turned simultaneously with the lifting the lateral inside edge.Type: GrantFiled: December 3, 2015Date of Patent: January 24, 2017Inventor: Walter D. Shannon, II
