Abstract: A four-section rise-over sofa bed fixture having a head section, a body section, an intermediate section and a foot section all pivotally connected together in end-to-end relationship and adapted to be folded from an extended coplanar position to a retracted position within a sofa. The fixture has at each side thereof a support to be mounted on the base of the sofa at the respective side thereof, a locking mechanism for locking the foot section in its retracted position, linkage interconnecting the support and the locking mechanism, and folding legs for supporting the body, intermediate and foot sections.

Abstract: A furniture assembly movable between a sitting configuration and a bed configuration including a support frame, a foldable bed frame supported by the support frame and movable between a folded and an unfolded position, the bed frame including an inner frame member supported by the support frame and an outer frame member pivotally movable between an extended position wherein it is generally coplanar with respect to the inner frame member and a folded position wherein it is located above the inner frame member, the inner and outer frame members defining a space therebetween when in the folded position for containing bedding material; guide means, such as tracks or the like, interconnect the support frame and the bed frame for guiding the movement of the bed frame between a stored position within the support frame and a deployed position in which the bed frame may be moved to the unfolded position; the assembly further including a closure device, such as a pivoted arm, operative when the bed frame is in the fold

Abstract: This pull out sofa bed is an improvement of the sofa bed disclosed in U.S. Pat. No. 3,984,883 dated Oct. 12, 1976 and assigned to the assignee of the present application. In said patent bed there is in effect a lost motion during which no work of compressing the mattress is being performed while slack is being taken up. Consequently the work required to compress the mattress and create the necessary locking of the compressed mattress, is concentrated over a relatively short part of the closing cycle of the folding of the bed. The result of this is that a relatively high "peak" force is required at this portion of the cycle to close the bed and compress the mattress and lock the bed in closed position, thereby requiring exertion of considerable strength by the person closing the bed. The patented bed is satisfactory when the mattresses were made of polyfoam.

Abstract: A furniture assembly such as a sofa bed which moves between a sitting configuration and a bed configuration including a metal support frame having end units with interconnecting beam members removably connected to the end units by bolts. A metal plate is secured to each end unit and includes a pair of slots inclined or slanted upwardly and forwardly from the rearward ends with U-shaped metal track members having flanges secured to the metal plates for defining laterally extending track surfaces. Inner and outer frames are pivotally connected together by an intermediate frame and are movable between a folded position and an unfolded position to define the bed configuration. The inner frame has bifurcated brackets secured thereto and shafts are connected to the bifurcated brackets and extend through the slots in the adjacent plates to support rollers which roll along the track members. The shafts have threaded nuts thereon and the shafts are the sole means for supporting the bed frames on the support frame.

Abstract: A convertible sofa bed particularly suited for use as a single bed. A sofa with a sloping seat resting on the frame partially beneath the back, with the forward seat support concealed behind the sofa frame front edge when the seat is in the retracted sofa position. A seat movable to an extended bed position and supported horizontally along opposite edges for stability, with the front support resting on the floor and with the rear support resting on the frame. Interengaging latch members on the seat and frame for limiting upward movement of the seat relative to the frame when in the retracted and extended positions.

Abstract: A sofa bed and sofa bed mechanism are disclosed wherein a three-piece support is employed for the sleeping cushioning element which retracts to a conventional sofa configuration and expands easily to provide a bed of conventional sleeping height. The mechanism is simple, rugged and tolerant of manufacturing variations.

Abstract: This pull-out sofa bed comprises a metal bed provided with a head section that can be raised to T.V. position, and releasably locked in such position, or released from such position and lowered to sleeping position, or folded over an adjacent long intermediate section of the bed to underlie the foot section of the bed folded thereover and also over said intermediate section, for compactness when shipping the bed. This bed has rear legs foldable underneath the intermediate section when the bed is fully collapsed, and also has means contacting the underside of the collapsed rear legs, to support the folded bed in a plurality of selected vertical levels of the sofa seat when the pull-out bed is collapsed and used as a sofa. The bed has means for locking the foot section of the bed to the intermediate section, in the folded or collapsed condition of the bed, to compress the mattress, which means is highly simplified and easy to manufacture.

Abstract: The bed or mattress frame for a convertible sofa is formed of at least two flat spring sections hinged along adjacent longitudinal edges and foldable into a storage position with the spring sections arranged in flat, overlying relationship with each other behind the front board of the sofa. As the sections are unfolded, a linking bar at each end of the frame activates a pivotally attached lever to lift the spring sections to a level above the front board.
