Abstract
Abstract In accordance with the invention there is provided a bed frame which is adjustable in width to king size and which at any width has great strength to the end that it has utility not only for beds with conventional bedding but also for water beds. The bed frame has longitudinal side rails and a longitudinal center rail, transverse end rails and a transverse center rail, the end rails and transverse center rail all being of adjustable length so as to enable adjustment of the bed to different widths and all being substantially coplanar with the longitudinal side rails and center rail, the bed having nine support legs one of which is directly underneath the connection between the transverse and longitudinal center rails and the other eight of which are adjacent the other connections between the transverse and longitudinal rails.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
183 words
A bed frame comprising two spaced, parallel, longitudinal side rails, two spaced, parallel, transverse end rails extending between and having their ends pivotally connected to said side rails, a longitudinal center rail between and extending parallel to said side rails and having ends disconnectably connected to said end rails, a transverse center rail between and extending parallel to said end rails and having ends disconnectably connected to said side rails and a center portion disconnectably connected to said longitudinal center rail, all of said longitudinal and transverse rails being in substantially the same plane, said transverse center rail and said transverse end rails each including a pair of rail members with center portions which overlap in telescoped relationship and which are adjustably connected together adjacent the connection of the transverse rail to said longitudinal center rail, a support leg secured to and extending downwardly from said frame underneath the connection between said longitudinal and transverse center rails, and a support leg secured to and extending downwardly from said frame adjacent each of the other connections between said longitudinal rails and said transverse rails.
Claim 2
Dependent Claim
183 words
A bed frame comprising two spaced, parallel, longitudinal side rails, two spaced, parallel, transverse end rails extending between and having their ends pivotally connected to said side rails, a longitudinal center rail between and extending parallel to said side rails and having ends disconnectably connected to said end rails, a transverse center rail between and extending parallel to said end rails and having ends disconnectably connected to said side rails and a center portion disconnectably connected to said longitudinal center rail, all of said longitudinal and transverse rails being in substantially the same plane, said transverse center rail and said transverse end rails each including a pair of rail members with center portions which overlap in telescoped relationship and which are adjustably connected together adjacent the connection of the transverse rail to said longitudinal center rail, a support leg secured to and extending downwardly from said frame underneath the connection between said longitudinal and transverse center rails, and a support leg secured to and extending downwardly from said frame adjacent each of the other connections between said longitudinal rails and said transverse rails.
Claim 3
Dependent Claim
33 words
A bed frame as set forth in claim 1 wherein said longitudinal center rail has a opening extending therethrough adjacent the center thereof and wherein said transverse center rail extends through said opening.
Claim 4
Dependent Claim
108 words
A bed frame as set forth in claim 2 wherein each of said longitudinal side rails has a channel facing toward the interior of the frame and wherein each of the ends of said transverse center rail is shaped and dimensioned to fit into the channel of one of the side rails and has secured thereto a plate with a portion thereof which is spaced from and parallel to the upper surface of the end of the transverse center rail and which lays against the upper surface of the side rail when said transverse center rail is assembled to said side rails thereby to provide the connections therebetween.
Claim 5
Dependent Claim
47 words
A bed frame as set forth in claim 3 wherein said plate has downwardly extending flanges at each side thereof with portions having upper edges which fit into the channel of and engage the side rail when the transverse center rail is assembled to the side rails.
