Adjustable width king size bed frames

Claim 2

A bedframe, comprising a pair of side rails, a pair of first cross rail sections pivotally secured to the side rails one adjacent each end thereof, a cross rail means for connecting to and extending between end portions of corresponding ones of said cross rail sections, and a center support means and characterized by the center support means being adapted to extend parallel to the side rails and being removably connectable at each end to one of said cross rail means by a pair of shouldered rivets projecting from the center support means at each end thereof, each cross rail means having a pair of slots for slidably receiving the rivets of the corresponding end of the center support means, and said slots being arcuate, the inner ends of the slots of each pair being spaced apart by a distance equal to the spacing of the rivets of each pair of rivets, the center of curvature of each slot being located at the center of the inner end of the other slot of the pair of slots.

Claim 3

A bedframe, comprising: a pair of side rails; a first cross rail section for each end of each side rail, one of the first cross rail sections being pivotally connected to the respective side rail adjacent each of the ends thereof, each first cross rail section having at least one notch adjacent the free end of the section and extending inwardly from the side edge of the section; a second cross rail section for connecting the free ends of the corresponding first cross rail sections, the second cross rail section having at least one rivet projecting therefrom adjacent each end thereof for engaging the notch of the corresponding first cross rail section, a center support rail extending parallel to the side rails and joined at its ends to the midpoints of the second cross rail sections by means of pairs of shouldered rivets secured to the center support rail and slidably received in slots in the second cross rail sections, and said slots being of opposite arcuate form and said second cross rail section is first engaged with said center support rail and then with said first cross rail sections.

Claim 4

A bedframe, comprising: a pair of side rails; a first cross rail section for each end of each side rail, one of the first cross rail sections being pivotally connected to the respective side rail adjacent each of the ends thereof, each first cross rail section having at least one notch adjacent the free end of the section and extending inwardly from the side edge of the section; a second cross rail section for connecting the free ends of the corresponding first cross rail sections, the second cross rail section having at least one rivet projecting therefrom adjacent each end thereof for engaging the notch of the corresponding first cross rail section, a center support rail extending parallel to the side rails and joined at its ends to the midpoints of the second cross rail sections by means of pairs of shouldered rivets secured to the center support rail and slidably received in slots in the second cross rail sections, and said slots being of opposite arcuate form and said second cross rail section is first engaged with said center support rail and then with said first cross rail sections.

Claim 5

A bedframe, as in claim 2 where the inner ends of the said slots of each pair being spaced apart by a distance equal to the spacing of the rivets of each pair of rivets, the center of curvature of each slot being located at the center of the inner end of the other slot of the pair of said slots.

Claim 6

The bedframe according to claim 2 wherein a pair of rivets are provided in spaced relation to one another on each second cross rail section, the first cross rail sections having pairs of notches with the spacing between the notches of each pair being the same as the spacing of the rivets of each pair of the rivets on the second cross rail sections, the spacing of the notches being arranged so that five notches will provide three sets of notches for engaging the rivets for adjusting the bedframe width.

Claim 7

The bedframe according to claim 2 wherein each notch has a first portion extending inwardly from the edge of the first cross rail section and a second portion extending parallel to the length of the section from the end of the first portion toward the free end of the section for locking engagement between said first and second cross rail sections.

Claim 8

The bedframe according to claim 1 wherein a pair of rivets are provided in spaced relation to one another on each said cross rail means, the first cross rail sections having a number of pairs of slots therein with the spacing between the slots of each pair being the same as the spacing of the rivets of each pair of the rivets on said cross rail means, the spacing of the slots being arranged so that five slots will provide three pairs of slots for engaging the rivets.
