Abstract
The present invention discloses a wheelstand for handicapped or immobile persons having a generally rectangular main frame rotatably supported on a ground support surface by relatively small wheels while larger wheels are rotatably mounted to the frame and manually rotated by the user in order to propel the frame. A generally planar body support structure is pivotally carried by the frame so that the angular position of the support structure can be varied with respect to the frame while still enabling the user to grip the larger wheels and propel the wheelstand.
