Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
168 words
A sofa bed comprising, a seat section, a back section pivotally movable with respect to said seat section and pivotally movable from an upright position adjacent said seat section where it forms a sofa to a horizontal position adjacent said seat section to form a bed, said back section having a pair of longitudinally extending leg means pivotally secured thereto with said longitudinally extending leg means in out-of-the-way position when the back section is in an upright position, with said longitudinally extending leg means movable to a substantially upright position when said back section is in a horizontal position to support said back section in such horizontal position adjacent said seat section, each said longitudinally extending leg means extending from adjacent each of the opposite sides of said back section longitudinally inward a substantial portion of the length of said back section so that the pair of longitudinally extending leg means when in leg supporting position extend substantially at least one-half of the length of said back section.
Claim 2
Dependent Claim
168 words
A sofa bed comprising, a seat section, a back section pivotally movable with respect to said seat section and pivotally movable from an upright position adjacent said seat section where it forms a sofa to a horizontal position adjacent said seat section to form a bed, said back section having a pair of longitudinally extending leg means pivotally secured thereto with said longitudinally extending leg means in out-of-the-way position when the back section is in an upright position, with said longitudinally extending leg means movable to a substantially upright position when said back section is in a horizontal position to support said back section in such horizontal position adjacent said seat section, each said longitudinally extending leg means extending from adjacent each of the opposite sides of said back section longitudinally inward a substantial portion of the length of said back section so that the pair of longitudinally extending leg means when in leg supporting position extend substantially at least one-half of the length of said back section.
Claim 3
Dependent Claim
23 words
A sofa bed as set forth in claim 1 in which locking means are provided to secure said back section in upright position.
Claim 4
Dependent Claim
65 words
A sofa bed as set forth in claim 1 in which the back section has a frame provided with a pair of leg receiving pockets and said leg means pivotally mounted and positioned in said pockets when said back section is in substantially upright position, said leg means being pivoted outwardly of said leg receiving pockets when said back section is in a horizontal position.
Claim 5
Dependent Claim
74 words
A sofa bed as set forth in claim 1 in which the seat section includes a pair of spaced side arms at the opposite sides of the seat section, and in which the back section has a back frame and means for pivotally securing said back frame to said side arms which includes a pivot pin extending through each of the opposite sides of the back frame and connected to the adjacent side arm.
Claim 6
Dependent Claim
39 words
A sofa bed as set forth in claim 3 in which stop means are provided to limit the outward movement of said leg means with respect to said back frame when said back frame is in a horizontal position.
Claim 7
Dependent Claim
38 words
A sofa bed as set forth in claim 4 in which a slideable rod engages the frames of the back section and the side arms for locking the back section in upright position relative to the seat section.
Claim 8
Dependent Claim
71 words
A sofa bed as set forth in claim 1 in which the back section has a frame member formed of a pair of spaced longitudinally extending rails connected at their opposite ends by end strips and spaced intermediate strips extending between said longitudinally extending rails and connected thereto, one of each of the pair of longitudinally extending leg means being pivotally connected between an end strip and an adjacent intermediate strip.
Claim 9
Dependent Claim
72 words
A sofa bed as set forth in claim 7 in which a longitudinally extending short strip is secured adjacent one of said longitudinally extending rails which forms the top rail of the back frame member with said short strip extending between the end strip and the adjacent intermediate strip and said short strip being engaged by the longitudinally extending leg means to hold said longitudinally extending leg means in leg supporting position.
