  • Patent number: 5601348
    Abstract: An assembly comprising one or more stationary wall units, each having a recess into which rigid platform is pivotally mounted. The platform forms a wall portion in its closed position, and a bed or couch in its open position. A second smaller platform or shelf/leg is pivotally mounted with a second recess or well set into the larger platform. The shelf/leg forms a wall portion in its open position, and a shelf or support leg in its open position, depending on the position of the larger platform. The larger platform itself maybe mounted adjacent to and in front of a pivotally mounted bedframe member, thereby allowing a single wall unit to be configured to form either a wall, a wall having an added shelf, a couch or a double bed.The invention further comprises a height adjustable table allowing both a lower height coffee table and a higher height card table. At its lower height the table can also provide support to the bedframe in its open position.
