  • Sofa bed
    Patent number: 4321717
    Abstract: A sofa bed is described herein which is converted from a seating mode to a bed through manual operation. The movable part of the bed forms the back of the sofa when disposed in a vertical mode and serves as the bed when disposed in a horizontal mode. The converting mechanism is simple and jam proof, resulting in a highly reliable sofa bed operation. Further, the sofa bed is capable of being manufactured almost entirely of wood, thereby limiting the metal requirements.
