Abstract
A walking aid for a handicapped person having a frame with wheels and brakes, handles attached to the frame at a suitable height for a person, who is enabled to push the walking aid along a walking surface, at least one brake operating assembly including a fixed handbar portion fixed as a handgrip extension of the handles, and a moveable member movably secured to the fixed handbar portion in coaxial relation so that the moveable member may be swung relative to the axis of the fixed portion, the moveable member being normally aligned with and substantially coaxial with the fixed portion, movement of said moveable member moving it out of coaxial alignment, and the brake cable being attached between the fixed portion and the moveable member so that movement of the moveable member will cause extension of the brake cable thus retarding the walking aid. Also disclosed is a folding mechanism for a walking aid, having swing arms linked together for swinging between extended and folded positions, and a lock for securing the arms in a semi-folded position and having a seat with height adjustments supported by the swing arms.
