  • Patent number: 7455308
    Abstract: A riding toy converts between a traditional or conventional upright trike configuration and a low slung chopper configuration. A front frame tube is joined to a head tube to which the front wheel and handlebars are piviotally attached. A rear frame tube is joined to a pair of rear wheels. The front and rear frame tubes are joined by a pivot shaft so that they rotate relative to one another. As a result, the rear portion of the riding toy may be flipped over to reconfigure the riding toy between the trike and chopper configurations. An opening is formed in the front frame tube and receives spring-loaded buttons that turn with the rear frame tube so that the riding toy may be locked in the desired configuration. The front frame tube is also split and features a clamp so that it can clamp down on a guide sleeve that is attached to the rear frame tube.
