A lock assembly is disclosed for use with a foldable walker. The lock assembly includes a lock pin movable between a first position in which the corresponding side member is held in a locked unfolded state and a second position in which the side member is in an unlocked folded state. A lock plate extends transversely to the longitudinal axis of the corresponding side member. The lock plate includes an aperture adapted to receive a locking end of the lock pin when the pin is in its first position and a guide trough limiting the side members to rotate relatively in a certain angles. A lever is connected to the lock pin such that when the lever is pushed down, the lock pin is moved from its first position to its second position and holds in the second position to permit rotation of the corresponding side member to its folded state.
