US Patent 7437783 Easily assembled bed frame

A bed frame that can be assembled without the use of additional tools. The bed frame generally comprises a pair of spaced side rails, retainer brackets secured to each side rail, and cross support members extending between the side rails. Each retainer bracket has a base section for supporting one of the cross support members and an aperture extending through the base section. The apertures are aligned with threaded bores in the cross support members so that threaded portions of respective leg assemblies may be inserted through the apertures and used to secure the cross support members to the corresponding retainer brackets.
