<p>A convertible couch comprises a mobile, spring supporting frame mounted on a fixed base and extending between two like lateral frames of the base. The mobile frame is divided into two frame parts having a length not exceeding the length of the lateral base frames and an intermediate frame part therebetween which has a length less than the height of the lateral base frames. The frame parts are interconnected by hinges so that the intermediate frame part may be pivoted in relation to a first one of the frame parts and a second one of the frame parts may be pivoted in relation to the intermediate frame part through an angle not exceeding 90 DEG about axes extending parallel to the head board of the couch. The intermediate and second frame parts are pivotal between a folded and a "bed" position, the first and second frame parts extending parallel to each other and being spaced apart by the intermediate frame part in the folded position, and all three frame parts extending in a plane projecting perpendicularly to the head board in the "bed" position. In the "bed" position, each of the first and second frame parts are supported by independent supports connected to the respective frame parts.</p> |
