Abstract
Abstract A seating unit which is convertible to a bed and comprises an outer seating section which is supported on a floor surface and which forms a slideable unit, and an inner section positioned within the outer seating section and supported on the same floor surface independently of the outer seating section. The inner section remains stationary as the outer section is slid longitudinally of the inner section so that the outer seating section forms a continuation of the stationary inner section to convert the unit to a bed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
156 words
A seating unit convertible to a bed comprising, an outer seating section, with said outer seating section having means at its opposite ends for independently supporting said outer seating section on a floor surface, which outer seating section forms a slideable unit, an independent inner section positioned within the outer seating section and with said inner section having means at its opposite ends for independently supporting said inner section on a floor surface independently of said outer seating section, said inner section being spaced from said outer section when said outer section is positioned over said inner section so that sliding of said outer section longitudinally with respect to said inner section does not affect said stationary inner section, said inner section remaining stationary as said outer section is slid longitudinally of said inner section so that the outer seating section forms a continuation of said stationary inner section to convert said unit to a bed.
Claim 2
Dependent Claim
156 words
A seating unit convertible to a bed comprising, an outer seating section, with said outer seating section having means at its opposite ends for independently supporting said outer seating section on a floor surface, which outer seating section forms a slideable unit, an independent inner section positioned within the outer seating section and with said inner section having means at its opposite ends for independently supporting said inner section on a floor surface independently of said outer seating section, said inner section being spaced from said outer section when said outer section is positioned over said inner section so that sliding of said outer section longitudinally with respect to said inner section does not affect said stationary inner section, said inner section remaining stationary as said outer section is slid longitudinally of said inner section so that the outer seating section forms a continuation of said stationary inner section to convert said unit to a bed.
Claim 3
Dependent Claim
27 words
A seating unit convertible to a bed as set forth in claim 1 in which the inner stationary section has an arm adjacent the outer end thereof.
Claim 4
Dependent Claim
29 words
A seating unit convertible to a bed as set forth in claim 1 in which the outer seating section has an arm rest adjacent one of the ends thereof.
Claim 5
Dependent Claim
57 words
A seating unit convertible to a bed as set forth in claim 3 in which the inner section has an arm adjacent the outer end thereof so that when the outer seating section is slid inwardly toward said stationary inner section the arm on said stationary section is adjacent the opposite end of the outer seating section.
Claim 6
Dependent Claim
54 words
A seating unit convertible to a bed as set forth in claim 1 in which one of said sections has stop means engaging the other section to prevent the separation of one section with respect to the other when said outer seating section is moved laterally outward with respect to said stationary inner section.
Claim 7
Dependent Claim
49 words
A seating unit convertible to a bed as set forth in claim 1 in which said sections have locking means for locking same together when said slideable seating section is positioned over said stationary inner section so that both said sections may be moved about as an integral unit.
Claim 8
Dependent Claim
96 words
A seating unit convertible to a bed as set forth in claim 1 in which the outer slideable seating section comprises a frame of generally rectangular shape having spaced longitudinal side rails and end rails and forming a pocket for receiving the stationary inner section, and in which the stationary inner section has a frame of generally rectangular shape having longitudinal side members and end members, and in which the longitudinal side members and top of the stationary inner section are spaced from the longitudinal side rails and end rails of the slideable outer seating section.
Claim 9
Dependent Claim
31 words
A seating unit convertible to a bed as set forth in claim 7 in which the frame of the seating section has an arm rest frame at the outer end thereof.
Claim 10
Dependent Claim
53 words
A seating unit as set forth in claim 7 in which the frame of the outer slideable seating section has legs at its opposite ends for independently supporting said frame and in which the frame of the inner stationary section has legs at its opposite ends for independently supporting said inner stationary frame.
