摘要:
A birdfeeder that is easily packed, delivered, assembled and disassembled. The birdfeeder is comprised of eight ⅛″ thick, flat parts that lock together by taking advantage of gravity and friction created by the use of a keyed mortise and tenon connection, such as that common to wood construction at the turn of the century. The eight parts disassembled pack flat as a kit for shipping and stocking. Once received the birdfeeder kit is easily assembled & disassembled, optionally without the use of tools or fasteners.
