Abstract

A sofa bed convertible from a sofa to a bed having a self-supporting stationary section, a first movable section slidably attached to the stationary section, and a second movable section slidably attached to the first movable section. Independently supported spaced arms are removably attached to the sides of the stationary section to serve as arm supports for persons seated on the sofa bed, but not as structural supports for the stationary section. A hollow furniture-type back is removably connected between the arms. A hinged mattress overlies the stationary and movable sections when the sofa bed is being utilized as a bed. The rearmost portion of the mattress may be doubled over so that the resulting double-thickness section may slide rearwardly and upwardly into the hollow back for storage, with the forward part of the mattress forming a resilient seating surface when the sofa bed is being utilized as a sofa. Alternatively, the forwardmost portion of the mattress may be doubled over to form a cushion-like seating surface with the rearwardmost single thickness section sliding into the hollow back for storage.

Dependent claims

A convertible sofa bed having a closed position forming a seating unit and an opened position forming a bed, said sofa bed comprising:

a self-supporting rectangular frame-like horizontal stationary section having a pair of spaced parallel end frame members, said members supporting a resilient horizontal surface defining a seating platform when said sofa bed is in the closed position;
a plurality of spaced load-bearing legs depending from and attached to the peripheral edge of said stationary section for supporting substantially entirely said section from the floor;
a first movable rectangular frame-like section formed by a pair of spaced parallel end frame members, said first movable section frame members supporting a resilient horizontal surface, said first movable section being slidable between said closed position wherein said first movable section underlies said stationary section, and an opened position wherein said first movable section is slid outwardly from said stationary section to a position where said horizontal resilient surfaces of said stationary and first movable section are substantially co-planar;
first connecting means joining said stationary section and said first movable section to permit linear sliding movement therebetween;
a second movable rectangular frame-like section formed by a pair of spaced parallel end frame members, said second movable section being slidable between said closed position wherein said second movable section underlies said first movable section, and an opened position wherein said second movable section is slid outwardly from said first movable section to a position where said horizontal resilient surfaces of said first and second sections are substantially co-planar;
and
second connecting means joining said first and second movable sections to permit linear sliding movement therebetween.

4 more elements

A convertible sofa bed having a closed position forming a seating unit and an opened position forming a bed, said sofa bed comprising;

a stationary frame-like section and at least one movable frame-like section linearly extensible from and connected to said stationary section, each of said sections having a substantially horizontal support surface, said surfaces being arranged in substantially parallel stacked relationship when said sofa bed is in said closed position, said surfaces being arranged in substantially co-planar relationship when said sofa bed is in said opened position;
a sofa back adjacent said stationary section, said sofa back having a hollow storage enclosure;
and
a resilient mattress positioned on said sofa bed, said mattress being hinged so that a portion of said mattress may be folded over a part of the remainder of said mattress to form a double thickness mattress section and a single thickness mattress section, said mattress being configured to overlie said co-planar surfaces to form a substantially planar upper surface when said sofa bed is in said opened position, a portion at least of said mattress being slid into said hollow storage enclosure of said sofa back when said sofa bed is in said closed position such that a portion at least of said mattress overlies said stationary frame-like section to form a seating surface.
