Patent number: 7293622Abstract: A weight-controlled, motorized vehicle can be accelerated in either direction, steered, or decelerated without hand controls and without repositioning of a rider situated atop the vehicle. Like a skateboard, the vehicle is normally ridden by a rider standing upon a platform on top of the vehicle with one foot in front of the other. The vehicle is propelled forward when the rider increases weight on the front portion of the platform and backward when weight is increased on the rear portion. The vehicle is steered like a skateboard, by tilting the platform from side-to-side. An improved drive system utilizes a single front drive wheel to power and steer the vehicle. The drive system eliminates need of a flexible power transmission coupling such as a U-joint or constant-velocity joint. It also eliminates need of the differential mechanism normally required for two laterally spaced drive wheels.Type: GrantFiled: January 26, 2004Date of Patent: November 13, 2007Inventor: Wade Spital

Patent number: 7261308Abstract: The cycle accessory system for child strollers can convert an ordinary child stroller into a multi-child transport unit. The multi-child transport unit can have at least four modes. The first mode (referred to herein as the “child control” mode) allows the lead child to power and steer the multi-child transport unit. (Note: even in child control mode, an adult has the ability to at least keep the multi-child transport unit stationary.) The second mode (referred to herein as the “adult control” mode) removes the ability of the lead child to power or steer the multi-child transport unit and returns control to an adult to power and steer the multi-child transport unit. The third mode is a multi-child transport unit storage mode. And the fourth mode is a tricycle mode.Type: GrantFiled: November 12, 2004Date of Patent: August 28, 2007Assignee: Contraption CorporationInventors: Kimberly S. Gwisdalla, John Michael Morgan
