ABSTRACT:
A sofa-bed mechanism for use in a sofa body having a relatively low seating level. The mechanism includes four sections foldable within the sofa body and alternatively extensible out of the sofa body to define a bed. The linkage which connects the four sections to the sofa body, and controls movement of those sections, includes an arrangement for permitting the mechanism to be located at a low level within the sofa body, and the lower rear corner of the mechanism to swing through a shallower arc than usual. The linkage also includes an arrangement for preventing the top section from experiencing opening movement, and for preventing the rear supporting leg of the mechanism from opening, until the sections move out from beneath the sofa body breast rail and the rear leg passes over the sofa body front rail. In one embodiment, the usual spring for aiding opening and closing movement of the mechanism is attached to movable pivots at both of its ends to increase the torque applied to the mechanism during its opening and closing movements.
