Abstract
Abstract A baby walker is disclosed having foldable legs, whereby the walker may be collapsed into a substantially flat form for shipping or transportation in a small carton for convenience in handling or storage. The foldable legs have a hinged joint, which is self-locking when the walker is in operative position, but can be easily unlocked when the legs are to be folded. A soft plastic covering is provided for covering the leg joints to prevent injury to the infant or damage to furniture, this covering being movable downwardly along the legs to expose the joints when the legs are to be folded.
