ABSTRACT:
A foldable walker includes a pair of side walking legs pivotally mounted on a pair of T joints, a front transverse bar secured between the two T joints, a pair of foldable links each pivotally connected between each T joint and each side walking leg, and a pair of seesaw controllers each fixed on an outer tube of a link and seesawly biasing a locking button resiliently retained in an inner tube of the link, whereby upon the depressing of the button by the seesaw controller, the inner tube will be telescopically received within the outer tube when folding the side walking legs toward the front bar, thereby resulting in a simpler, quicker and more convenient folding operation of the walker.
