Patent ID: 8820763

Claim:
A device for human conveyance comprising: a front wheel; a rear wheel; a frame member interfacing the front wheel to the rear wheel whereas the front wheel is held at a constant distance from the rear wheel and whereas the front wheel and the rear wheel are rotatably interfaced to the frame member; a resilient platform, a forward edge of the resilient platform interfaced to the frame member in proximity to the front wheel, whereas downward pressure on the resilient platform creates an increase in a distance between the forward edge of the resilient platform and a distal rearward edge of the resilient platform; a resilient frame member situated between the means for creating a rearward movement from a downward movement and the frame member, the resilient frame member absorbing shock from a downward movement of the means for creating rearward movement; and a means for converting the increase in the distance between the forward edge of the resilient platform and a distal rearward edge of the resilient platform into a rotational movement of the rear wheel.
