Abstract
A rollator designed to provide low-radius rotational mobility while a user is engaged in motion with a foldable and height adjustable frame allowing a user to have a natural full gait. The foldable frame has an angled upright U-shaped main frame section and a base U-shaped frame section mounted to the angled upright U-shaped frame and a U-shaped intermediate frame section mounted to the angled U-shaped upright frame section and the base U-shaped frame section. A moveable seat assembly is slideably mounted to the U-shaped support assembly to assume desire positions. A pair of rear wheels are mounted to the frame and a pair of front wheels are mounted to yoke mechanisms which are mounted on the frame. A brake assembly including brake levers are mounted to the frame, the brake assembly being operatively connected to the pair of rear wheels to brake the rear wheels with each of the brake levers being adapted to transfer braking force from the user hand grip lever to the rear wheels.
