Abstract
Abstract A sofa bed construction of the type having a sofa frame and a bed frame which is adapted to be stored within the sofa frame when in a collapsed condition but which can also be opened into a bed. The sofa frame of the invention consists of metal members which define flanges at particular locations. The sofa frame is adapted to be covered with upholstery material with the material extending between flanges defined by the respective metal frame members. A plurality of clips are provided for securing the upholstery material to the flanges. These clips comprise U-shaped resilient members having side walls adapted to fit around the flanges and associated upholstery material. These clips thereby resiliently hold the material in position relative to the metal frame members.

Claim 1
Independent Claim
287 words
A sofa bed comprising a collapsible metal bed frame assembly, a substantially rigid, metal, sofa frame assembly, said sofa frame assembly including a sofa front metal frame portion, a sofa right side metal frame portion, a sofa left side metal frame portion and a sofa rear metal frame portion, metal flange portions formed on each of said metal frame portions, means for covering said sofa frame assembly, said covering means comprising a cover fabric, said cover fabric including a first cover fabric portion covering said front metal frame portion and lying in a first generally vertically disposed plane, a second cover fabric portion covering said rear metal frame portion and lying in a second generally vertically disposed plane, a third cover fabric portion covering said right side metal frame portion and lying in a third generally vertically disposed plane and a fourth cover fabric portion covering said left side metal frame portion and lying in a fourth generally vertically disposed plane, and each of said fabric portions defining inturned portions extending to said metal flange portions, means for securing said inturned fabric portions to said metal flange portions, said securing means comprising a plurality of resilient clips, each of said clips including means for engaging a cover fabric portion fitted into engagement with a metal flange portion and for providing a bias force to maintain said engaged cover fabric portion in a relatively stationary contacting engagement with one of said metal flange portions, at least some of said metal flange portions being disposed on said metal frame portions of said sofa frame assembly out of the generally vertically disposed planes formed by their respective cover fabric portions such that said resilient clips are substantially hidden from view.
Claim 2
Dependent Claim
287 words
A sofa bed comprising a collapsible metal bed frame assembly, a substantially rigid, metal, sofa frame assembly, said sofa frame assembly including a sofa front metal frame portion, a sofa right side metal frame portion, a sofa left side metal frame portion and a sofa rear metal frame portion, metal flange portions formed on each of said metal frame portions, means for covering said sofa frame assembly, said covering means comprising a cover fabric, said cover fabric including a first cover fabric portion covering said front metal frame portion and lying in a first generally vertically disposed plane, a second cover fabric portion covering said rear metal frame portion and lying in a second generally vertically disposed plane, a third cover fabric portion covering said right side metal frame portion and lying in a third generally vertically disposed plane and a fourth cover fabric portion covering said left side metal frame portion and lying in a fourth generally vertically disposed plane, and each of said fabric portions defining inturned portions extending to said metal flange portions, means for securing said inturned fabric portions to said metal flange portions, said securing means comprising a plurality of resilient clips, each of said clips including means for engaging a cover fabric portion fitted into engagement with a metal flange portion and for providing a bias force to maintain said engaged cover fabric portion in a relatively stationary contacting engagement with one of said metal flange portions, at least some of said metal flange portions being disposed on said metal frame portions of said sofa frame assembly out of the generally vertically disposed planes formed by their respective cover fabric portions such that said resilient clips are substantially hidden from view.
Claim 3
Dependent Claim
59 words
A sofa bed as defined in claim 1 wherein each of said resilient clips comprises a generally U-shaped member having an elongated base portion and two wall portions, each of said wall portions forming an acute angle of a first magnitude at its juncture with said base portion when said resilient clip is in a non-stressed or unbiased condition.
Claim 4
Dependent Claim
79 words
A sofa bed as defined in claim 2 wherein each of said wall portions forms an angle of a second magnitude at its juncture with said base portion when said resilient clip is in a stressed or biased condition due to its engagement of a cover fabric portion and its maintenance of said engaged cover fabric portion in a relatively stationary contacting engagement with one of said metal flange portions, said second magnitude being greater than said first magnitude.
Claim 5
Dependent Claim
18 words
A sofa bed as defined in claim 3 wherein said U-shaped member comprises an integrally formed plastic member.
Claim 6
Dependent Claim
52 words
A sofa bed as defined in claim 1 wherein said front frame portion includes first and second metal flange portions for receiving said resilient clips, said first and second metal flange portions being disposed in a fifth plane, said fifth plane being substantially parallel to and horizontally spaced from said first plane.
Claim 7
Dependent Claim
49 words
A sofa bed as defined in claim 1 wherein said rear frame portion includes a third metal flange portion for receiving said resilient clips, said third metal flange portion being disposed in a sixth plane, said sixth plane being substantially parallel to and horizontally spaced from said second plane.
Claim 8
Dependent Claim
46 words
A sofa bed as defined in claim 1 wherein said right side frame portion includes a fourth metal flange portion for receiving said resilient clips, said fourth metal flange portion being disposed in a seventh plane, said seventh plane being substantially perpedicular to said third plane.
Claim 9
Dependent Claim
46 words
A sofa bed as defined in claim 1 wherein said left side frame portion includes a fifth metal flange portion for receiving said resilient clips, said fifth metal flange portion being disposed in an eighth plane, said eighth plane being substantially perpendicular to said fourth plane.
