Abstract
A folding walker with side frames rotationally mounted on both ends of a front frame such that the side frames can rotate independently from a closed position where they are parallel to the front frame to an open position where the side frames are perpendicular to the front frame and parallel to each other. The side frames are locked in the open position by fixed plates that are mounted on the front frame. Detents with lever releases are mounted on the side frames. The detents releasably engage the fixed plates when the side frames are in the open position.
