Walking aid device
A walking aid device includes a support body inclusive of a plurality of support elements extending toward the ground. Each support element is coupled to a caster and a brake unit. Each brake unit has a clutching surface. The clutching surface controllably clutches a wheel of the caster or the ground to thereby generate friction for stopping the walking aid device.
