  • Patent number: 6055688
    Abstract: A wall-mounted station for changing the diapers of a baby comprises a base configured for being vertically mounted to a wall and defining a base plane and a baby platform hingedly mounted to the base and defining a platform plane. The baby platform is operable for being movable between an opened position wherein the platform plane is disposed generally perpendicular to the base plane for the platform to receive a baby and a closed position wherein the platform plane is generally parallel to the base plane. A stop structure extends from a rear edge of the baby platform proximate the base and generally perpendicular to the platform plane. A mounting pad is positioned on the base and is disposed generally parallel to the base plane. The stop structure is operable for abutting against the mounting pad when the baby platform is moved to an open position to support the platform and maintain the baby platform perpendicular to the base when the weight of a baby is placed thereon.
