Abstract
A walker having a unique leg support system in which the walker's two stationary front legs are interchangeable at the user's discretion with two wheeled front legs, both types of legs being height adjustable relative to the walker's framework. The wheeled front legs are connectable to the walker's frame so the wheels can be oriented on either the outboard or the inboard of the walker's front leg. Each wheeled front leg includes a wheel axle and a pivot axle connected thereto, the pivot axle being pivotably connected to a front leg so the front leg can roll along a support surface, e.g., ground, on the wheel when the wheel is pivoted to a first position and so the front leg's foot can stand stationary on the support surface when the wheel is pivoted to a second position. The wheel is continuously spring loaded toward the first position where the wheel axle abuts the front leg's exterior surface so the walker's wheeled leg is biased into the first position when the walker is not in use, but can be pivoted to the second position in response to a user's downward force on the walker when it is in use.
