 Abstract: |
To provide support and protection for an impaired person, a four-corner lower frame is provided, made of heavy metal, to insure a low center of gravity, which has two wheels at the rear corners operable about fixed axes of rotation, and a single central front caster wheel. The four corners of the frame, which is of generally U-shape, for example in form of an open square or rectangle, are formed with projecting spurs which project downwardly, with clearance from the ground surface, over which the walker is to operate, of about 1 cm. An upper frame, with padded arm rests and a forward front portion including a steering bar, is provided, secured to the lower frame by uprights located behind the center of the side legs, preferably close to the rear wheels, to provide a support for the person, for example by resting the elbows and forearms on the arm rest, with the hands grabbing the steering bar. Tilting the entire frame backwards, only slightly, will cause the rear spurs to engage the ground, thus providing braking, for example on an inclined surface; the two forward spurs at the forward corners of the open U provide assurance against tipping, and additional braking.
