Abstract

A wheelchair includes a pair of posts and a base having a middle portion pivotally coupled to the posts so as to allow the base to rotate from a horizontal position to an erecting position. A rod is engaged in the middle of the wheelchair for engaging with the base so as to maintain the base in the horizontal position. A lower frame has an upper portion pivotally coupled to the front end of the base for moving the front end of the base downward so as to erecting the base when the rod is disengaged from the base. The wheelchair may be folded to a compact structure for carrying purposes.
