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. A leg member is pivotally connected to the intermediate frame and includes gear teeth disposed about the pivotal connection to the intermediate frame to coact with gear teeth on the inner frame whereby the leg member is moved to a leg supporting position upon relative pivotal movement between the intermediate frame end and the inner frame. A handle-leg unit is pivotally connected to the outer frame and includes first and second links pivotally connected together whereby the links may be moved from a collapsed stored position to an extended position for supporting the outer frame when in the bed configuration. A pin and an L-shaped slot interconnect the links for locking the links against relative pivotal movement. A catch or pin is disposed on the inner frame for coaction with the slot in one of the links whereby that link positions the inner and outer frames relative to one another when in the folded position and to selectively prevent the outer frame from being pivoted toward the unfolded position from the folded position.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
145 words
A furniture assembly for movement between a sitting configuration and a bed configuration comprising; support frame means, bed frame means movable between a folded position and an unfolded position, said bed frame means being in said folded position when in said sitting configuration and in said unfolded position when in said bed configuration, means interconnecting said bed frame means and said support frame means for allowing movement of said bed frame means relative to said support frame means, said bed frame means including at least first and second mattress frames pivotally connected together for movement between said folded and unfolded positions, and foldable handle-leg means pivotally connected to said second frame for moving said second frame from said folded position toward said unfolded position and for moving to a support position to act as a leg to support said second frame in said unfolded position.
Claim 2
Dependent Claim
145 words
A furniture assembly for movement between a sitting configuration and a bed configuration comprising; support frame means, bed frame means movable between a folded position and an unfolded position, said bed frame means being in said folded position when in said sitting configuration and in said unfolded position when in said bed configuration, means interconnecting said bed frame means and said support frame means for allowing movement of said bed frame means relative to said support frame means, said bed frame means including at least first and second mattress frames pivotally connected together for movement between said folded and unfolded positions, and foldable handle-leg means pivotally connected to said second frame for moving said second frame from said folded position toward said unfolded position and for moving to a support position to act as a leg to support said second frame in said unfolded position.
Claim 3
Dependent Claim
84 words
An assembly as set forth in claim 1 wherein said handle-leg means includes a first link pivotally connected at a first end thereof to said second frame and extending to a second end, a second link pivotally connected at an inner end thereof to said second end of said first link and extending to a distal end, said first and second links being movable between a collapsed-stored position and said support position, and lock means for selectively preventing relative pivotal movement between said links.
Claim 4
Dependent Claim
47 words
An assembly as set forth in claim 2 including catch means on said first frame for coacting with at least a portion of said lock means when said links are in said collapsed position for preventing unfolding movement of said second frame relative to said first frame.
Claim 5
Dependent Claim
57 words
An assembly as set forth in claim 4 wherein said pivotal connection between said first link and said second link allows movement of said second link longitudinally of said first link, said lock means includes an L-shaped slot extending into said first link and a pin extending from said second link for coacting with said L-shaped slot.
Claim 6
Dependent Claim
41 words
An assembly as set forth in claim 4 wherein said handle-leg means includes one of each of said first and second links disposed adjacent each end of said frames, and a handle bar interconnecting said distal ends of said second links.
