Abstract: A joint for securing a tubular member to a support member comprises a pair of extruded holes in the sidewall of the tubular member opposite each other, a hole in the support member, the tubular member being disposed against the support member with the extruded holes in alignment with the hole in the support member, and a self-tapping fastener engaging the support member and passing through the hole therein to threadedly engage both extruded holes, the threaded fastener having cut complementary threads in both extruded holes during fastening.

Abstract: A latch unit for a pair of rectangular telescoped bed frame rails having overlapped side walls with aligned openings therein. The latch unit consists of a hollow rectangular body of one-piece, non-rigid construction, preferably yieldable plastic material, telescoped over the telescoped rails.

Abstract: A bed carrying frame comprising a pair of generally parallel side rail members, of hollow rectangular shape, a pair of end rail units, each of which consists of two relatively telescoped end rail members which are also of hollow rectangular shape, and corner bracket members mounting each of the end rail members on one of the side rail members. The corner bracket members are substantially identical and function to pivotally mount the end rail members on the side rail members for movement between folded positions in which two end rail members are folded against each side rail member and assembled positions in which pairs of end rail members are relatively telescoped and cooperate with the side rail members to form a rectangular frame. A novel latch unit is provided for each pair of relatively telescoped end rail members to maintain the end rail members in predetermined relative positions.
