ADJUSTABLE WHEEL SUSPENSION ASSEMBLY FOR A WHEELED WALKER

摘要

An adjustable wheel suspension assembly for a wheeled walker providing both lateral and longitudinal stability under load. With a calibrated spring preload adjustment, the wheel suspension assembly provides lateral stability for any particular user body weight and a wheel deflection working stroke sufficient to absorb wheel shocks over irregular terrain. The wheel suspension assembly is particularly advantageous for upright wheeled walkers.
