Convertible bed

A bed kit including components capable of being assembled in the field in one way to produce a mattress-support frame having a small size to support a narrow and short first mattress to provide a small bed and in another way to produce a mattress-support frame having a relatively larger size to support a relatively wider and longer second mattress to provide a large bed, the bed kit comprising

• a variable-width headboard including interlocking and relatively movable first and second movable headboard segments, the second movable headboard segment being mounted for movement relative to the first movable headboard segment to expand or contract the width of the variable width headboard, a first bed leg coupled to the first movable headboard segment, and a second bed leg coupled to the second movable headboard segment,
• a variable-width footboard including interlocking and relatively movable first and second movable footboard segments, the second movable footboard segment being mounted for movement relative to the first movable footboard segment to expand or contract the width of the variable-width footboard, a third bed leg coupled to the first movable footboard segment, and a fourth bed leg coupled to the second movable footboard segment,
• a first variable-length side wall including a first rail associated with the headboard and a second rail associated with the footboard and mounted for movement relative to the companion first rail to expand or contract length of the first variable-length side wall,
• a second variable-length side wall including a first rail associated with the headboard and a second rail associated with the footboard and mounted for movement relative to the companion first rail to expand or contract the length of the second variable-length side wall,
• a headboard segment-motion lock comprising a short headboard cap configured to provide means for locking the first and second movable headboard segments of the variable-width headboard in a drawn-together first relative position to establish a narrow width of the variable-width headboard and a relatively longer long headboard cap configured to provide means for locking the first and second movable headboard segments of the variable-width headboard in a spread-apart second relative position to establish a relatively wider wide width of the variable-width headboard,
• a footboard segment-motion lock comprising a short footboard cap configured to provide means for locking the first and second movable footboard segments of the variable-width footboard in a drawn-together first relative position to establish a narrow width of the variable-width footboard and a relatively longer long footboard cap configured to provide means for locking the first and second movable footboard segments of the variable-width footboard in a spread-apart second relative position to establish a relatively wider wide width of the variable-width footboard,
• a first side-wall lock arranged to lock the first and second rails of the first variable-length side wall in a drawn-together first relative position to establish a short length of the first variable-length side wall and in a spread-apart second relative position to establish a relatively longer long length of the first variable-length side wall,
• a second side-wall lock arranged to lock the first and second rails of the second variable-length side wall in a drawn-together first relative position to establish a short length of the second variable-length side wall and in a spread-apart second relative position to establish a relatively longer long length of the second variable-length side wall,
• a set of relatively short slats, and
• a set of relatively longer long slats,
• wherein only short slats in the set of relatively short slats are arranged to interconnect opposing rails in the first and second variable-length side walls to establish a first mode of the bed when the narrow width is established for each of the variable-width headboard and footboard and the short length is established for each of the variable-length side walls, and
• wherein only long slats in the set of relatively longer long slats are arranged to interconnect opposing rails in the first and second variable-length side walls to establish an alternate second mode of the bed when the relatively wider wide width is established for each of the variable-width headboard and footboard and the relatively longer long length is established for each of the variable-length side walls.
