Extendable folding bed frame

A foldable bed frame comprising:

• a pair of first sub-frames, each first sub-frame comprising:
• a pair of opposing spaced apart longitudinal bars, each longitudinal bar having a first end and a second end, the opposing longitudinal bars fixedly connected together by at least a first lateral support bar proximate opposing longitudinal bar first ends and a second lateral support bar proximate opposing longitudinal bar second ends, the pair of first sub-frames pivotally connected together proximate corresponding longitudinal bar first ends by first pivotal connecting members, the opposing longitudinal bars of at least one first sub-frame being extendable with respect to the first pivotal connecting members along longitudinal axis of the at least one first sub-frame;
• a first leg assembly fixedly attached to the first sub-frames proximate the first pivotal connecting member;
• a pair of second leg assemblies, each second leg assembly pivotally attached to each first sub-frame proximate second ends of opposing longitudinal bars;
• wherein the pair of first sub-frames are pivotable from an open configuration wherein each first sub-frame is aligned longitudinally to form a generally rectangular co-planar support surface, and a folded configuration wherein each first sub-frame is substantially overlapped and adjacent to each other.

A foldable bed frame comprising:

• a pair of first sub-frames, each first sub-frame comprising:
• a pair of spaced apart longitudinal bars, each longitudinal bar having a first end and a second end, the opposing longitudinal bars fixedly connected together by a plurality of lateral support bars, the pair of first sub-frames pivotally connected together at corresponding longitudinal bar first ends by first pivotal connecting members, wherein the pair of first sub-frames are pivotable from an open configuration whereby each first sub-frame is aligned longitudinally to form a generally rectangular co-planar support surface and a folded configuration whereby each first sub-frame is substantially overlapped and adjacent to each other;
• a first leg assembly fixedly attached to the first sub-frames proximate the first pivotal connecting member;
• a pair of second leg assemblies, each second leg assembly pivotally attached to each first sub-frame;
• and
• at least one coupling member for attaching the first sub-frames to an adjacent structure;
• wherein the at least one coupling member comprises a base having a plurality of opposing outer walls extending downwardly from opposing edges of the base and at least one inner wall extending downwardly from an inner portion of the base substantially parallel to the outer walls such that a plurality of engaging spaces are formed between the walls.
