Problems solved by technology

[0005] Conventional wheelchairs with only "manual hub" propulsion offer no mechanical advantage (MA), so propulsion over long distances is a difficult job, especially when going uphill
An additional disadvantage is that power is interrupted and energy is wasted every time the manual hub is gripped and released due to force discontinuities
For many wheelchair users, propulsion over long distances can be strenuous and strenuous for the shoulders and wrists
Manual wheelchairs are limited primarily for outdoor use due to their lack of maneuverability

Embodiment Construction

[0054] Figure 1A and Figure 1B A general conceptual set of component systems illustrating several configurations of the present invention, as may be understood by the term "system".

[0055] 1. Propulsion system 100 (labeled 101-199)

[0056]

[0057]

[0058]

[0059] Each of the systems includes features that can be understood by the skilled person to be its own inventive embodiment, entirely independent of the embodiment of the manually propelled vehicle. Therefore, the skilled person should understand that not only TRIKE TM Inventive features are encompassed as a whole, but also inventive components and configurations applicable to other human-powered vehicles or even partially human-powered vehicles. For example, a telescoping support frame may be considered an invention applicable to conventional wheelchairs as well as the manually propelled vehicles discussed here.

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.

Description

[0001] Priority Document Reference [0002] This application claims priority under 35 U.S.C. § 119 to U.S. Provisional Application No. 61 / 202,802, filed April 7, 2009, entitled ""Rowing-motion Propelled Wheelchair Generating Power from Rowing Motions in Both Directions" , which is incorporated by reference for all purposes. This application also claims priority to US Application Serial No. 12 / 555,239, filed September 8, 2009, which is also incorporated by reference for all purposes. technical field Background technique [0003] Many of the existing manually propelled wheelchairs designed to increase power efficiency do not take into account certain repetitive motion injuries that are particularly problematic for persons confined to wheelchairs. Although power is the focus of these devices, the potential damage to even the most able-bodied of those using such devices can be catastrophic to the mobility of a wheelchair bound person, even if the damage is benign like tendonitis...
