  • Patent number: 7913980
    Abstract: A portable game hoist (10) designed for raising and lowering game feeders and fallen game animals in the field. The invention consist of a compact and collapsible triangular support frame which contains a plurality of pulleys in a block and tackle arrangement. The block and tackle can be actuated by a hoist rope (92) to raise and lower game feeders/game animals providing a 6:1 lift to pull ratio. One pulley in the block and tackle arrangement is limited to rotation in a single direction and is positioned to automatically lock as objects are being hoisted. Locking pulley (50) can be unlocked by activating the locking pulley release (49) via the locking pulley release line (51) to allow pulley rotation in either direction. Therefore, unlocking the locking pulley (50) allows all six pulleys to rotate in either direction permitting the lowering of hoisted objects. The triangular support frame includes means for attachment to a tree or pole including a method for hanging temporarily to aid with final attachment.
