ABSTRACT:
A collapsible portable manual wheel chair is converted to a collapsible electric wheel chair. The two large rear wheels of the collapsible manual wheel chair are removed, and an electromechanical drive unit is substituted in their place. The drive unit includes a left drive wheel assembly, a right drive wheel assembly, a battery mounting assembly, and a control device supplying electric power to each of the drive wheel assemblies for propelling and steering the wheel chair. The left and right drive wheel assemblies and the battery carrier assembly are each manually removable from the wheel chair frame to permit collapsing the wheel chair frame and are each manually removable from one another to provide portable light weight components.
