Abstract

An invalid dolly for transporting an individual such as a patient or invalid between various sitting locations, for example, on a bed, on a toilet, or in a wheelchair, has a pair of front wheels with a pair of fixed crutch tips in front of and slightly above the front wheels, a pair or rear caster wheels, a diagonally upwardly extending handle, a padded cushion and hand and foot crossbars. The dolly is tipped toward the individual to a position where the handle is nearly vertical and the dolly is resting on the pair of fixed crutch tips. The patient grips a crossbar handle with his chest or stomach against the cushion and with his feet resting on a footbar. The helper or orderly then draws the handle toward him pivoting the dolly onto a pair of front wheels and eventually also onto a pair of rear casters 21. The patient is then resting on the cushion and is wheeled to a new location and the process reversed to deposit him again in a sitting position.
