Abstract
Abstract A tree step which provides a safe and efficient method for a person to climb a tree without inflicting damage to the tree. The device comprises a frame having a pair of hooks thereon, a landing projecting from the frame for placement of a foot, and a line for securing the frame to the tree. The line is secured at one end to the frame and has an intermediate reach which encircles the tree and a free end reach which is adapted to be wound a plurality of times around the hooks. The frame is then moved relative to the tree to lock the line in place around the hooks.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
182 words
A tree step comprising a frame and means for securing the frame to a tree, said means comprising a pair of hooks on the frame, each hook having a mouth for entry into a space bounded by the hook, and a line secured at one end to the frame having an intermediate reach adapted to encircle the tree and a free end reach adapted to be wound a plurality of times around the hooks, with each wind of line passing through the mouths of the hooks into said hook spaces, the mouth of at least one hook being sufficiently narrow to permit passage therethrough of only one diameter of line at a time whereby after said free end reach of line is wound around the hooks, said frame may be moved relative to the tree to effect passage of a portion of said intermediate reach of line through the mouth of said one hook to a position in said hook space blocking passage of said end reach back out through said mouth thereby to prevent the line from unwinding from the hooks.
