Pull-out folding sofa beds

Abstract

This bed comprises a front forwardly extending foot section having rearwardly extending side arms. Said side arms have similar, symmetrically disposed, horizontal offset portions raised above the horizontal plane of the bed mattress supporting fabric of the bed platform when the bed is in open sleeping position. In the closed position of the bed, the foot section projects rearwardly and said offset portions are then disposed below the horizontal plane of the mattress supporting fabric and hence in a depressed plane. The fabric is connected to each of a pair of zig-zag springs disposed alongside said depressed portions (in the closed position of the bed), at points disposed inwardly of the ends of the zig-zag springs, and also by a pair of helical tension springs to the side arms, at locations beyond the outer ends of said depressed portions. With such construction, persons sitting at the ends of the sofa (when the bed is closed) have a softer, more comfortable seat, because of the depressed side portions of the foot section and because of less tension on the fabric, and also more relaxing, softer seating between the ends of the sofa, because of use of less helicals to connect the fabric to the bed frame at the sides of said foot section. The ends of the zig-zag springs are furthermore received in the end helical springs on each side of the foot section to house and encase said ends.
