Bed frame assembly

Claim 1

A bed frame comprising: a pair of spaced parallel side frame members, each having a coplanar portion defining a first surface; a pair of longitudinally spaced cross frame members extending perpendicularly between said side frame members, said cross frame members each having a coplanar portion defining a second surface; one of said surfaces being vertically spaced from the other surface to form a support for a box spring and mattress; and combined means for detachably securing each end of said cross frame members to one of said side frame members and for supporting said frame, said securing and supporting means being defined solely by slidably interengaging complementarily tapered male and female elements, each female element having a central portion with flanges at opposite sides thereof, said flanges having portions extending toward one another and defining a passageway which forms means confining its respective male element for vertical movement relative thereto, each male element having outwardly extending flanges at opposite sides thereof defining an insert slidably positionable in said passageway, the flanges on both of said elements being gradually complementarily tapered from a first end having a given width to a second end having a smaller width, said flanges being uniformly tapered between their ends, whereby said insert and passageway are tapered, one element being on one of the frame members that define said one surface and the other element being on one of the frame members that define said other surface, a downwardly extending floor engaging abutment carried by each of said latter elements, each element on said cross frame members extending outwardly from one end thereof into position for free sliding engagement with an element on one of said side frame members, whereby said cross frame members are mounted for limited vertical movement relative to said side frame members so that said elements are wedged into interlocking relationship with one another by forces applied to said one surface by said box spring and mattress and the reaction force of said abutments against the floor.
