Abstract:
1. A bedstead assembly including a rigid support frame and a top plate unit disposed on and above said support frame, wherein said support frame includes a first foldable frame member convertible between unfolded and folded states, at least one pivot unit, and a second foldable frame member having an end connected pivotally to an end of said first foldable frame member by said pivot unit, each of said first and second foldable frame members including a plurality of parallel non-foldable plates and at least one pair of foldable plates, any two adjacent ones of said non-foldable plates interconnecting pivotally one corresponding pair of said foldable plates to define a void space when said first foldable frame member is in the unfolded state, each of said foldable plates including two pivotable plate portions having outer ends connected respectively and pivotally to said corresponding non-foldable plates such that each of said pivotable plate portions is pivotable relative to a corresponding one of said non-foldable plates about a first axis, and inner ends interconnected pivotally, said first and second foldable frame members having respectively aligned top surfaces, said pivot unit being disposed adjacent to said top surfaces such that one of said first and second foldable frame members is pivotable about a second axis to abut against said top surface of the other of said first and second foldable frame member, said first and second axes forming an angle therebetween, said pivotable plate portions being generally perpendicular to said non-foldable plates when said support frame is in the unfolded state and being generally parallel to said non-foldable plates when said support frame is in the folded state.
