Abstract
Abstract A bedframe which may be easily adjusted for use as a single, double, or queen size bed. The frame has a pair of side rails and first and second cross rail sections connected to each side rail. One of the cross rail sections has a pair of upwardly projecting shoulder rivets and the other side rail section has, preferably, three pairs of L-shaped notches with the notches of each pair being spaced apart by a distance equal to the separation of the rivets of the other cross section and with the pairs being separated by distances equal to the differences in the desired width of the frame.

Claim 1
Independent Claim
381 words
An adjustable width bedframe, comprising: a pair of side rails, a first cross rail section for each side rail, the first cross rail section being connected at one end thereof to the side rail adjacent a first end of the side rail, the first cross rail section having two spaced upwardly projecting headed rivet means located adjacent the free end of the section, said rivet means including shank portions, the two said first cross rail sections being positioned at opposite ends of the individual said side rails to which the individual cross rail section connects, a second cross rail section for each side rail, the second cross rail section being connected at one end thereof to the side rail adjacent the second end of the side rail, the second cross rail section having at least two spaced pairs of notches adjacent the free end of the section for receiving the rivet means of the first cross rail section whereby the first cross rail sections of each side rail can be connected to the second cross rail sections to form a pair of cross rails extending across the frame at opposite ends thereof to form an adjustable width bed frame of standard sizes, said rivet means heads engaging the upper surface of the second cross rail sections to retain the cross rail sections in engagement, the second cross rail sections each having a horizontal flange, the notches being substantially L-shaped slots of substantially uniform width throughout that extend inwardly from an edge of the horizontal flange of each second cross rail section and then laterally outwardly of its associated side rail, the width of said shank portions being substantially equal to the width of said slots, and the substantially L-shaped notches all being open to an edge of a second cross rail section but with the notches open ends facing in opposite directions longitudinally of the frame when the frame is operatively positioned, the distance between the centers of said shank portions being equal to the distance between the centers of said notches open ends of each of said pair of notches, engagement of the headed rivet means with the substantially L-shaped notches requiring relative movement of the first and second cross rail sections longitudinally and then transversely outwardly of the frame.

An adjustable width bedframe, comprising: a pair of side rails, a first cross rail section for each side rail, the first cross rail section being connected at one end thereof to the side rail adjacent a first end of the side rail, the first cross rail section having two spaced upwardly projecting headed rivet means located adjacent the free end of the section, said rivet means including shank portions, the two said first cross rail sections being positioned at opposite ends of the individual said side rails to which the individual cross rail section connects, a second cross rail section for each side rail, the second cross rail section being connected at one end thereof to the side rail adjacent the second end of the side rail, the second cross rail section having at least two spaced pairs of notches adjacent the free end of the section for receiving the rivet means of the first cross rail section whereby the first cross rail sections of each side rail can be connected to the second cross rail sections to form a pair of cross rails extending across the frame at opposite ends thereof to form an adjustable width bed frame of standard sizes, said rivet means heads engaging the upper surface of the second cross rail sections to retain the cross rail sections in engagement, the second cross rail sections each having a horizontal flange, the notches being substantially L-shaped slots of substantially uniform width throughout that extend inwardly from an edge of the horizontal flange of each second cross rail section and then laterally outwardly of its associated side rail, the width of said shank portions being substantially equal to the width of said slots, and the substantially L-shaped notches all being open to an edge of a second cross rail section but with the notches open ends facing in opposite directions longitudinally of the frame when the frame is operatively positioned, the distance between the centers of said shank portions being equal to the distance between the centers of said notches open ends of each of said pair of notches, engagement of the headed rivet means with the substantially L-shaped notches requiring relative movement of the first and second cross rail sections longitudinally and then transversely outwardly of the frame.
Claim 3
Dependent Claim
38 words
A bedframe as in claim 1 where a plurality of pairs of notches or slots are provided at spaced positions of the second cross rail sections to provide an adjustable width frame having a plurality of standard sizes.
Claim 4
Dependent Claim
58 words
A bedframe As in claim 1 where the open ends of the notches face inwardly of the assembled frame, and the frame side rails are adapted when operatively assembled to engage a standard width box spring so as to be prevented thereby from moving toward each other and thereby retaining said frame and cross rails in assembled position.
Claim 5
Dependent Claim
58 words
A bedframe as in claim 2 where the open ends of the notches face inwardly of the assembled frame, and the frame side rails are adapted, when operatively assembled, to engage a standard width box spring so as to be prevented thereby from moving toward each other and thereby retaining said frame and cross rails in assembled position.
