Abstract
A folding walker includes a first frame of two parallel main supports separated by a horizontal cross bar. An inverted U-shaped second frame has one leg pivotally affixed to each main support of the first frame and pivotal between an extended operable position and a folded storage position. At least one brace extends from an intermediate portion of a leg of the second frame and is pivotally affixed thereto, and an upper end of the brace is slidably attached to an upper portion of one of the main supports of the first frame. At least one tension brace extends between a lower portion of one of the main supports of the first frame and one of the legs of the inverted U-shaped second frame. The tension brace is intermediately hinged wherein a first segment of the tension brace is pivotal with respect to a second segment of the tension brace.
