20080315548 | VEHICULAR WHEELCHAIR DOCKING AND CAPTURE APPARATUS - A transit vehicle docking system including a pair of press plates driven inwardly against the opposite side of a wheelchair docked in a docking space in a transit vehicle. | 12-25-2008 |
20100059963 | DUAL-DRIVE BICYCLE - A dual-drive bicycle has a front wheel provided with a transmission device including: an active sprocket at a top end or another portion of a steering post; a transmission sprocket on one side of an axle of the front wheel; and a chain connecting the active sprocket and the transmission sprocket for power transmission. When mounted at the top end of the steering post, the active sprocket has both ends of its axle extended and equipped with driving handlebars for steering the bicycle and driving the front wheel. When mounted at another portion of the steering post, the active sprocket has one end of its axle extended and equipped with a driving handlebar for driving the front wheel. Thus, in addition to a conventional rear-wheel driving structure, the bicycle has a front-wheel driving device allowing the bicycle to be selectively driven by the rear wheel, the front wheel or both. | 03-11-2010 |
20120187649 | Rowing-Motion Propelled Wheelchair Generating Power from Rowing Motion in Both Directions - 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. | 07-26-2012 |
20140306420 | SINGLE LEVER DRIVE SYSTEM - A human-powered-system utilizing an arm lever assembly and/or a pedal assembly to be adapted to or incorporated into other mechanisms including, but not limited to, wheelchairs and vehicles. The arm lever assembly includes an arm lever that is reciprocated to provide power and rotated left or right to provide steering control. Both assemblies are operatively connected to a convertor, utilizing gears and one-way clutches that receives the reciprocal movements of the arm lever and converts them into a unidirectional output, to be utilized in combination or independently. The arm lever is further telescoping and when utilizing a slide mechanism operatively connected to the convertor representing a first class lever offers a range of various leverages by correspondingly changing the length of the force and load end when extended and retracted. | 10-16-2014 |
