ABSTRACT:
A portable chair lift for use by a hunter and the like for raising the person off the ground by means of a line extending over a limb. The device includes a frame member which has a seat hung downwardly therefrom on ropes. A worm gear assembly is carried by the frame member to which a hand operated crank is connected for rotating the worm. A pulley is carried on the same shaft as a gear forming part of the worm gear assembly and has a coiled length of web material provided therefrom. The rope is tied to the end of the web material. As a result of the worm gear, the chair lift can be raised with very little effort and the web material aids in stabilizing the chair. The entire chair is collapsible into a compact package for transporting from one site to another.
