  • Patent number: 5509151
    Abstract: A two frame sofa bed recliner has a seat frame and back frame. The frames are elevated from the floor on supports. The frame ends are linked, overlapped, interengaging the seat frame with the back frame, enabling a simple conversion reconversion process from sofa bed to recliner. In recliner position the back frame tilts rearward on its end. The back frame is interlocked with the seat frame locked by a detent, retaining means and a second detent in a guide. Conversion and reconversion are effected by rotating the interlocked unit on to the back frame supports, disengaging the seat frame and back frame, then lowering the seat frame to the floor on the supports and interlocking the frames. For reconversion the process is reversed. A removable arm rest is attachable.

  • Patent number: 5327591
    Abstract: A three piece sofa bed recliner has an end frame, seat frame and back frame. The frame ends are linked overlapped. Interengaging the seat frame with the back frame enables a simple conversion process from sofa bed to recliner. The back frame and end frames fold toward each other as the interlocked seat frame is moved backward. The end frame and back frame interlock with the end frame leg and the seat frame and back frame interlock releases during conversion. Reconversion is a simple forward pull unfolding the respective frames on their legs with an extending pivoted leg set between the end frame and back frame. Wheels facilitate movements. The end frame may be used to be a chaise lounge.
