  • Patent number: 4901998
    Abstract: A multi-functional activity table to be used as a play/learning tool for children of all ages. The apparatus comprises three main components including a table top, pedestal and domed base, each of which can be employed separately or in combination with one or more of the others for a child's amusement and instruction. The apparatus is easily converted into the following: art table, water table, sandbox, rocker, toss game, crawl-through and tee ball toy. The apparatus not only represents a substantial saving in cost over that which would be required to acquire an individual toy for each activity but also has nesting features which allow one to store the apparatus in much less space than would be possible with equipment designed only for each individual game. Furthermore, the multi-functional activity table offers many attractive features not available with single game-type apparatus.
