  • Patent number: 4205669
    Abstract: A diaper-changing aid for infants or retarded children, comprising a base which supports a vertical barrier of mesh, netting or other soft yieldable material which extends across the baby's chest. The barrier keeps the baby's hands out of the way and occupied. It is preferably stretched across an arch-shaped frame, with elastic fastened along the middle portion of the lower edge of the netting. One side of the arch is pivoted or hinged to the base, so that it can be swung up. The baby is then laid down on the base and the arch swung down and its opposite end fastened down by a suitable catch device. The elastic extends across the baby's chest. The diapering process may then proceed on the lower side of the barrier. Toys may be hung from the arch. Adjustable ankle straps may be provided at the lower portion of the base. The base may be made of a solid sheet of composition board or the like with padding on top.
