Abstract
A transport wheelchair comprises a frame with a chair base movably carried by a wheel base displaceable on a set of wheels. A seat, a backrest and a legrest are carried by the chair base of the frame. The set of wheels comprises a pair of fixed wheels to rotate around a laterally-oriented rotational axis and to roll longitudinally. A pivot wheel is coupled to the frame and oriented perpendicular to the pair of fixed wheels and to rotate around a longitudinally-oriented rotational axis. The pivot wheel is selectively positionable between: an elevated position higher than a bottom of the pair of fixed wheels and off of the ground; and a lowered position lower than the bottom of the pair of fixed wheels with the pair of fixed wheels elevated off of the ground and the pivot wheel to roll laterally.
