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.

A leg support system comprising first and second main support legs, first and second mobile legs, each of said mobile legs being connectable to one of said main support legs, each mobile leg being usable to support a minor operational load relative to ground with said leg\s foot being supported above ground so that said leg is mobile relative to ground when in the minor load support mode, and said mobile leg also being usable to support a major operational load relative to ground with said leg\s foot resting on ground so that said leg is not mobile relative to ground when in the major load support mode, said mobile legs being separate and independent one from the other when disconnected from said two main support legs, a wheel connected to each of said mobile legs for rendering said mobile legs mobile in the minor operational load support position, each wheel being positioned to one side of its associated support leg relative to the expected motion direction of said support leg when said mobile leg is connected to said main support leg, and a connector device for connecting each pair of main support and mobile legs, said connector device being partially carried by said main support leg and said mobile leg of each pair, said connector devices cooperating with said main support legs to allow said first and second mobile legs to be connected to said first and second main support legs, respectively, and also to allow said first and second mobile legs to be connected to said second and first main support legs, respectively, both said connector devices cooperating to permit said wheels to be positioned adjacent to each other inboard of said main support legs, or separated one from the other by said main support legs outboard of said main support legs, as desired by the user when said mobile legs are connected to said main support legs.
