Abstract
Abstract A bedframe in which side rails are interconnected by adjustable end crossbars, each crossbar comprising a pair of elongate angle sections connected with the side rails and having nested overlapped adjacent end portions manually interconnectible at a plurality of selectable positions to provide a plurality of different standard bed widths, the connecting means comprising permanently affixed pin and spring clip members which are manually operable without the necessity of using supplemental tools.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
113 words
In a bedframe having side rails, interconnected by end crossbars respectively having a pair of sections manually releasably interconnectable in nested relation at a plurality of selectable positions to provide a plurality of standard bed widths, comprising: a. connecting means on one of the sections of each end crossbar operable to engage a portion of the other section of the end crossbar at each selectable bed width position, and at the selected bed width position to anchor the connected sections against axial relative movement; and b. manually releasable latch means carried by one of said sections including a spring clip for retaining the sections in connected nested relation at the selected bed width.
Claim 2
Dependent Claim
113 words
In a bedframe having side rails, interconnected by end crossbars respectively having a pair of sections manually releasably interconnectable in nested relation at a plurality of selectable positions to provide a plurality of standard bed widths, comprising: a. connecting means on one of the sections of each end crossbar operable to engage a portion of the other section of the end crossbar at each selectable bed width position, and at the selected bed width position to anchor the connected sections against axial relative movement; and b. manually releasable latch means carried by one of said sections including a spring clip for retaining the sections in connected nested relation at the selected bed width.
Claim 3
Dependent Claim
59 words
A bedframe according to claim 1, wherein the spring clip is generally U-shaped and has a long leg and a short leg, the outer end of the long leg being secured to said one of said sections, and the short leg being adapted to resiliently snap over adjacent edges of the nested sections and retain the same against un-nesting.
Claim 4
Dependent Claim
22 words
A bedframe according to claim 2, in which the adjacent edges are provided with registered notches for receiving said short leg therein.
Claim 5
Dependent Claim
39 words
A bedframe according to claim 1, wherein the connecting means on said one of the sections comprises a projecting pin, and securing means for said pin which serves to secure the spring clip to said one of said sections.
Claim 6
Dependent Claim
125 words
In a bedframe having side rails interconnected by end crossbars respectively having a pair of sections manually releasably interconnectable in nested relation at a plurality of selectable positions to provide a plurality of standard bed widths, comprising: a. connecting means on one of the sections of each end crossbar including a plurality of spaced pins receivable in openings provided in the other section of the end crossbar at each selectable bed width position, and operable at the selected bed width position to anchor the connected sections against axial relative movement; and b. manually releasable latch means carried by one of said sections including a spring clip associated with each of said pins for retaining the sections in connected nested relation at the selected bed width.
Claim 7
Dependent Claim
125 words
In a bedframe having side rails interconnected by end crossbars respectively having a pair of sections manually releasably interconnectable in nested relation at a plurality of selectable positions to provide a plurality of standard bed widths, comprising: a. connecting means on one of the sections of each end crossbar including a plurality of spaced pins receivable in openings provided in the other section of the end crossbar at each selectable bed width position, and operable at the selected bed width position to anchor the connected sections against axial relative movement; and b. manually releasable latch means carried by one of said sections including a spring clip associated with each of said pins for retaining the sections in connected nested relation at the selected bed width.
