Abstract
The present invention solves many of the problems for the wheelchair bound individual who wants an ergonomically sensible, convenient, yet powerful and stable wheelchair. The Trike's unique power source is provided by a rowing-type motion of the user rather than the less efficient “hand rim” grip or wrist propulsion. Power is generated both in the out rowing stroke and the in rowing stroke through a inventive power drive. The rowing motion significantly reduces the chances for repetitive stress injuries, like carpal tunnel. Furthermore, the rowing motion and movements are designed to facilitate efficient propulsion and steering in combination, to be effected simultaneously. The rowing motion allows the user's full arm strength and full range of motion to assist in the powering of the vehicle.
