Abstract
Abstract A molded plastic one-piece bed frame support leg having a pair of parallel, laterally spaced upper flange means, a U-shaped section connecting the flange means together and adapted to receive a leg of a cross rail angle therein, and a center tubular support section connecting to one of the flange means and blending into part of the U-shaped section. A caster can be completely received in and supported by the lower end of the tubular support section which is vertically extending when the bed frame is in use.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
78 words
A bed frame leg comprising a one-piece molded plastic body including a pair of parallel laterally spaced upper flange means, a U-shaped section connecting said flange means together and adapted to receive a leg of a cross rail angle therein, and a center tubular support section connecting to one of said flange means and blending into part of said U-shaped section, one of said upper flange means being adapted to have a bed frame cross rail secured thereto.
Claim 2
Dependent Claim
78 words
A bed frame leg comprising a one-piece molded plastic body including a pair of parallel laterally spaced upper flange means, a U-shaped section connecting said flange means together and adapted to receive a leg of a cross rail angle therein, and a center tubular support section connecting to one of said flange means and blending into part of said U-shaped section, one of said upper flange means being adapted to have a bed frame cross rail secured thereto.
Claim 3
Dependent Claim
27 words
A bed frame leg as in claim 1 where said U-shaped sEction terminates at laterally spaced bottom portions thereof into strengthening webs blending into said support section.
Claim 4
Dependent Claim
53 words
A bed frame leg as in claim 1 where an upwardly protruding stop lug is formed at a center portion of one of said flange means to abut on an edge of a side rail and limit arcuate movement of a cross rail when the leg is operatively engaged with a bed frame.
Claim 5
Dependent Claim
97 words
A bed frame leg comprising a one-piece molded plastic body including a tubular center support, upper flange means extending in opposite directions from said center support at its upper end, a lower support flange spaced laterally from but parallel to said upper flange means, said flange means and said support flange having adjacent parallel laterally inner edges, and a generally U-shaped section connecting at its upper ends to the adjacent laterally inner edges of said flange means and said flange and blending into a wall of said center support at the lower end of said U-shaped section.
Claim 6
Dependent Claim
97 words
A bed frame leg comprising a one-piece molded plastic body including a tubular center support, upper flange means extending in opposite directions from said center support at its upper end, a lower support flange spaced laterally from but parallel to said upper flange means, said flange means and said support flange having adjacent parallel laterally inner edges, and a generally U-shaped section connecting at its upper ends to the adjacent laterally inner edges of said flange means and said flange and blending into a wall of said center support at the lower end of said U-shaped section.
Claim 7
Dependent Claim
176 words
The combination in a bed frame comprising a bed frame leg formed as a one-piece molded plastic body including a tubular center support, upper flange means, a lower support flange spaced laterally from but parallel to said upper flange means, said flange means and said support flange having adjacent parallel laterally inner edges, and a generally U-shaped section connecting to the adjacent laterally inner edges of said flange means and said flange and blending into a wall of said center support at the lower end of said U-shaped section; and a metal angle cross rail having one flange received in said U-shaped section and a second flange bearing on said lower support flange, a metal angle bed frame side rail, a securing means extending through legs of said side rail and cross rail, and said lower support flange to secure the cross rail and support leg pivotally to the side rail, and rivet means extending through said U-shaped section and said flange of said cross rail for securing said cross rail to said bed frame leg.
Claim 8
Dependent Claim
176 words
The combination in a bed frame comprising a bed frame leg formed as a one-piece molded plastic body including a tubular center support, upper flange means, a lower support flange spaced laterally from but parallel to said upper flange means, said flange means and said support flange having adjacent parallel laterally inner edges, and a generally U-shaped section connecting to the adjacent laterally inner edges of said flange means and said flange and blending into a wall of said center support at the lower end of said U-shaped section; and a metal angle cross rail having one flange received in said U-shaped section and a second flange bearing on said lower support flange, a metal angle bed frame side rail, a securing means extending through legs of said side rail and cross rail, and said lower support flange to secure the cross rail and support leg pivotally to the side rail, and rivet means extending through said U-shaped section and said flange of said cross rail for securing said cross rail to said bed frame leg.
Claim 9
Dependent Claim
49 words
The combination as in claim 5 where an upwardly protruding stop lug is formed at a center portion of said upper flange means to abut on an edge of a side rail and limit arcuate movement of a cross rail to a position extending perpendicularly to the side rail.
Claim 10
Dependent Claim
32 words
The combination as in claim 5 where said upper flange means supports said side rail, and said second flange of said cross rail is positioned below and movable under said side rail.
Claim 11
Dependent Claim
34 words
A bed frame leg as in claim 1 where said support section has a continuous periphery at a bottom portion thereof, and an upper portion of said support section has an interrupted inner periphery.
