Abstract: Bed frame members are provided for quick, snap-together, interlocking assembly for preventing relative rectilinear motion between members without loose or screwthread parts. One member has a first slot with an enlarged retaining portion and a mating member has a projection thereon for entrance into the slot. The projection carries a Belleville washer having its conical convex face disposed for engagement with the slot for compression as the projection moves thereinto and for retaining engagement with the periphery of the enlarged retaining portion of the slot when the projection has been fully inserted in the slot. A second slot in one member has a portion disposed at a substantial angle to the first slot and receives a second projection disposed on the other member.

Abstract: A mounting assembly for hanging a bunk bed ladder from the upper bunk of a bunk bed wherein the vertical flange of one of the upper bed rails is formed with a pair of slots each having an entry portion disposed above and communicating with a narrower retaining portion. A pair of hanger brackets are attached to the bunk bed ladder each bracket having a mounting leg with a narrow region slightly narrower than the retaining portion of the slots and an outer region wider than the retaining portion but slightly narrower than the entry portion of the slots. The mounting legs of the hanger brackets are arranged for insertion through the entry portions of the slots to position the narrow regions thereof for lowering into the retaining portions of the slots, in which they are retained against lateral movement or inadvertent withdrawal by being positioned on the horizontal flange of the bed rail and under the box spring that is supported on the bed rail horizontal flange.
