Abstract
Abstract A bed assembly comprising a metal frame of generally rectangular configuration including a pair of opposed side rails and a pair of opposed end rails and a plurality of metal slats extending transversely between the side rails in spaced parallel relationship to one another and to the end rails. Both of the end and side rails have a hollow cross section along their respective lengths. The hollow cross section in each of the rails is defined at least by two metal members welded together. The end rails of a first embodiment and all of the rails of a second embodiment are defined by a pair of U-shaped members having their legs overlapping with the bases of the U shapes spaced from one another to define the hollow cross section. The side rails of the first embodiment are defined by channeled members having a channel extending therealong and a plate-like strip covering the channel to define the hollow cross section. Each of the slats has a cross section including a base, downwardly extending diverging legs and a flange extending laterally outwardly from the lower end of each leg. Spring retaining apertures are disposed in the bases of the slats and the end rails for engaging and gripping a spring inserted into the aperture. Three tabs extend into each aperture and each aperture is disposed in a concavity for guiding the spring into each aperture.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
107 words
A bed assembly comprising; metal frame means of generally rectangular configuration including a pair of opposed side rails and a pair of opposed end rails, at least one of said rails including first and second metal members defining a hollow cross section along the length thereof, each of said first and second members being U-shaped in cross section with said second U-shaped member having shorter legs than said first U-shaped member, said legs of said first and second U-shaped members being in engagement with one another and secured together with the base portions of said U-shaped members being spaced apart to define said hollow cross section thereof.
Claim 2
Dependent Claim
107 words
A bed assembly comprising; metal frame means of generally rectangular configuration including a pair of opposed side rails and a pair of opposed end rails, at least one of said rails including first and second metal members defining a hollow cross section along the length thereof, each of said first and second members being U-shaped in cross section with said second U-shaped member having shorter legs than said first U-shaped member, said legs of said first and second U-shaped members being in engagement with one another and secured together with the base portions of said U-shaped members being spaced apart to define said hollow cross section thereof.
Claim 3
Dependent Claim
37 words
An assembly as set forth in claim 1 wherein said base portions are parallel to one another and said legs are parallel to one another with said legs extending in the same direction to define spaced flanges.
Claim 4
Dependent Claim
28 words
An assembly as set forth in claim 2 wherein a first leg of said first member is in flat engagement with a first leg of said second member.
Claim 5
Dependent Claim
28 words
An assembly as set forth in claim 3 wherein a second leg of said first member is in flat engagement with a second leg of said second member.
Claim 6
Dependent Claim
18 words
An assembly as set forth in claim 4 wherein said first legs of said members are welded together.
Claim 7
Dependent Claim
18 words
An assembly as set forth in claim 5 wherein said second legs of said members are welded together.
Claim 8
Dependent Claim
19 words
An assembly as set forth in claim 5 wherein said second legs of said members are integrally connected together.
Claim 9
Dependent Claim
47 words
An assembly as set forth in claim 4 including a pair of said rails and a plurality of metal slats extending transversely therebetween, the ends of said slats being disposed on said first legs of said members, said slats and said first legs all being welded together.
Claim 10
Dependent Claim
25 words
An assembly as set forth in claim 8 wherein the tops of said slats engage said second legs of said members and are welded thereto.
Claim 11
Dependent Claim
29 words
An assembly as set forth in claim 9 wherein said rails are defined by one continuous rail having its ends secured together about the periphery of said frame means.
Claim 12
Dependent Claim
60 words
An assembly as set forth in claim 4 wherein another of said rails includes a metal channeled member and a metal closure member, said channeled member having a generally U-shaped channel extending longitudinally therealong, said closure member extending longitudinally along said channeled member and secured thereto adjacent said channel for covering said channel to define said hollow cross section thereof.
Claim 13
Dependent Claim
40 words
An assembly as set forth in claim 11 wherein said channeled member is recessed along said channel for receiving said closure member, said closure member being a flat strip so that said closure member is flush with said channeled member.
Claim 14
Dependent Claim
31 words
An assembly as set forth in claim 11 including slat support flanges defined by said channeled members and extending laterally inwardly toward one another from the sides of said frame means.
Claim 15
Dependent Claim
37 words
An assembly as set forth in claim 13 wherein said slat support flanges define the bottom of said side rails and each side rail includes a top flange extending inwardly generally parallel to said slat support flanges.
Claim 16
Dependent Claim
23 words
An assembly as set forth in claim 14 wherein said slat support flanges and said top flanges are spaced from said adjacent channels.
Claim 17
Dependent Claim
26 words
An assembly as set forth in claim 15 wherein each of said side rails includes a vertical flange extending vertically upwardly from said top flange thereof.
Claim 18
Dependent Claim
44 words
An assembly as set forth in claim 16 including a plurality of metal slats extending transversely between said side rails in spaced parallel relationship to one another and to said end rails, the ends of said slats being disposed upon said slat support flanges.
Claim 19
Dependent Claim
124 words
A bed assembly comprising; metal frame means of generally rectangular configuration including a pair of opposed side rails and a pair of opposed end rails, at least one of said rails including a pair of metal members defining a hollow cross section, one of said members being a channeled member and the other being a closure member, said channeled member having a generally U-shaped channel extending longitudinally therealong, said closure member extending longitudinally along said channeled member and secured thereto adjacent said channel for covering said channel to define said hollow cross section, said channeled member being recessed along said channel for receiving said closure member, said closure member being a flat strip so that said closure member is flush with said channeled member.
Claim 20
Dependent Claim
