  "abstract": "An improved adjustable cross frame member for use in a bed frame having side frame members and another such adjustable cross frame member. The improved member is comprised of first and second elongate L-shaped elements having mutually perpendicular legs. The first element is provided with a plurality of pairs of longitudinally spaced keyhole shaped slots in one leg, each slot having a narrow portion and an enlarged portion, and the second element is provided with a pair of rivets on the corresponding leg, longitudinally spaced to match the slot spacing. The rivets have an enlarged head and a narrow shank portion matching the corresponding slot portions in width so that upon positioning the elements in leg abutting engagement and longitudinally moving the elements relative to each other, the rivets are positioned in the narrow slot portions and hold the elements together positively. In order to lock the elements longitudinally in this position, the first element includes position defining apertures between each pair of slots, and the second element includes a releasable resilient member having a detent between the rivet pair which engages a position defining aperture when the rivets become positioned in the narrow slot portions.",
  "claims": [
    "1. An adjustable elongated bed frame member adapted to extend transversely between a pair of horizontally disposed further bed frame members so as to hold said further bed frame members in spaced parallel relationship, said adjustable member comprising: a first elongated L-shaped element having first means adjacent one end for fastening said first element to one of said pair of further bed frame members, said element including first and second mutually perpendicular flat legs; a second elongate Lshaped element having second means adjacent one end for fastening said second element to the other of said pair of further frame members and including first and second mutually perpendicular flat legs; at least one protrusion extending from said first leg of said first element; means defining a plurality of longitudinally spaced openings in said first leg of said second element permitting said protrusion to be inserted when like legs of said elongate elements are positioned in face-abutting engagement with one another; means defining a plurality of longitudinally spaced, position-defining apertures in said second elongate elements, with one of said apertures being associated with each opening on said second elongate element, said first elongate element being provided with a single access aperture longitudinally spaced from said protrusion and positioned in registration with a selected one of said position-defining apertures when the protrusion is positioned within the opening associated with said selected position-defining aperture; a releasable locking member extending generally along one of the legs of said first elongate element, said member being secured at one end thereof at a fixed location upon said one leg and being movable toward and away therefrom, said member having an insert at the other end thereof adaptable to be passed through said access aperture and into said selected position-defining aperture upon the movement of said member toward said access aperture, whereby upon such passage of said insert into said selected position-defining aperture and said access aperture, said first and second elongate elements are locked in positively held together relationship and position of adjustment until movement oF said member away from said access aperture to withdraw said insert from said selected position-defining aperture.",
    "2. A bed frame member as in claim 1, in which said locking member, access aperture and protrusion are all located upon the same leg of said second elongate element.",
    "3. A bed frame member as in claim 1, in which said first leg of said said first element has a pair of protrusions, and said longitudinally-spaced openings are arranged in a plurality of pairs, with said protrusions being spaced apart longitudinally by a distance substantially equal to the distance between the openings of one of said opening pairs.",
    "4. A bed frame member as in claim 3, in which one of said openings is common to two of said pairs of openings.",
    "5. A bed frame member as in claim 3, in which each of said openings is in the form of a longitudinally elongated slot having a narrow portion at one end of predetermined transverse width and an enlarged portion at the opposite end of transverse width greater than said predetermined width, and each protrusion is in the form of a rivet extending outwardly from said first leg of said first element, each rivet having a shank portion similar in width to said narrow slot portion and an enlarged head having an external dimension larger than said narrow slot portion and smaller than said enlarged slot portion, said shank portion being of a height allowing said enlarged head to clear said first leg of said second elongate element, said rivets being adapted for respective insertion through the enlarged slot portions of a selected one of a slot pair when like legs of said elongate elements are positioned in face-abutting engagement with one another, said rivets being positioned in the narrow slot portions of said selected slot pair when said first and second elongate elements are moved longitudinally relative to one another so that said first and second elements are positively held against separation.",
    "6. A bed frame member as in claim 5, in which said locking member comprises a thin, flat, elongate, inherently resilient member connected at one end of said other elongate element and passing over said access aperture, said resilient member having a detent defining said insert at said access aperture adapted to pass therethrough and engage within the selected position defining aperture when said rivets are positioned in the narrow slot portions of the associated slot pair to lock first and second elements in said positively held together relationship and position of adjustment, said resilient member also having a manually graspable portion for withdrawing the member against its resilient bias and releasing said elements.",
    "7. A bed frame member as in claim 6, in which said access aperture is initially spaced longitudinally from the selected one of said position-defining apertures when said rivets are positioned in the enlarged portions of said slots said access aperture being finally positioned in registry with the selected position-defining aperture when said rivets are positioned in the narrow slot portions of said associated slot pair."
