Arm powered tricycle and method of movement

Abstract

An arm powered tricycle that has a frame with a passenger seat that is capable of forward, backward, or circular motion. The frame has a front wheel that consists of a sphere horizontally and rotatably mounted on an axle that can also rotate about a vertical axis so that it provides universal motion for the front wheel. The rear wheels are independently mounted on separate axles so that they rotate separately from one another. The rear axles are U-shaped in mid section with two concentric and parallel opposing ends that are rotatably mounted on the frame on one end, and are fixedly mounted to the wheel hub on the other end. Vertically pivotal levers are separately and individually furnished and mounted on each lateral side of the frame and are linked with a drive rod to the rear drive axles. The tricycle steers by slowing or stopping both arm levers to lock the rear wheels. Pushing the vertical levers back and forth provides rotation to the rear axles for propulsion. Pivot arrangements are also provided so that the vertical levers may be rotated back against the rear wheels for ease of mounting and dismounting.
