Ergonomical multi-speed wheelchair

Abstract

This invention relates generally to mechanics, and more specifically, to systems and methods for providing an ergonomical multi-speed wheelchair. In one embodiment, the invention includes a vehicle for providing ergonomical operation, the vehicle including a frame, the frame having a rear wheel and a front wheel, the rear wheel being rotationally coupled to the frame via a rear wheel shaft, the frame including a drive linkage pulley; a drive bar, the drive bar being slidably mounted to the frame; a slotted reel, the slotted reel mounted on the rear wheel shaft; and a drive linkage, the drive linkage mounted to the drive bar, the drive linkage looping over the drive linkage pulley before being coupled to the slotted reel, wherein sliding the drive bar towards the drive linkage pulley results in the drive linkage coiling around the slotted reel, wherein sliding the drive bar away from the drive linkage pulley results in the drive linkage uncoiling from the slotted reel, and wherein uncoiling of the drive linkage operates to rotate the rear wheel shaft and the rear wheel to propel the frame.
