  • Patent number: 5327838
    Abstract: A play table with integral storage areas accessible through the play surface has a frame which supports a horizontal board having one or more openings. A removable storage bin is suspended within each opening. Atop each opening, a removable panel is provided. Preferably, the panels collectively cover the entire surface area of the board, thus providing a smooth play or work surface. When articles stored in a bin are needed, the panel overlying the bin is removed and its contents withdrawn, either piecemeal or by removing the bin itself. The panel then is replaced atop the opening, thus restoring the smooth play surface to its entirety. When the articles need to be returned to the storage bin, the appropriate panel is removed and the articles may either be swept or placed into the bin.
