  • Patent number: 5244443
    Abstract: A closed-wall barrier fits on top of a baby walker of conventional construction. It blocks a baby's reach, in order to prevent the baby from grasping dangerous objects. The barrier completely encircles the front, back and sides of the tray of the walker. The barrier may also have a top, which top may or may not be removeable. The barrier may completely cover and enclose the top of the walker. However, preferably it will have an opening or openings which the parent can use to insert the infant into the seat of the walker, and to hand objects to the infant, but which openings are too high for the infant to use to reach out.
