Abstract
Abstract A fence climber especially for use with an open-mesh cross wire, wire loop fence is made up of a rod bent upon itself into a half-circular arc near its center to provide a semi-loop that can engage and rest upon a fence wire. From the semi-loop, two legs extend at a slight divergence from each other, each leg having near one end an out-turned step extending about at a right angle to the adjacent leg and having a roughened upper surface to receive a shoe sole. The steps are about coplanar and are at an angle to the central, semi-loop. In some cases, each step is bent back upon itself to form a lower rod extending far enough toward the center to be engageable with the open mesh of the fence.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
73 words
A fence climber for use with a fence that has a wire mesh construction comprising a rod near its center bent into an approximately half-circular arc merging with two substantially equal legs each of which continues into an out-turned step portion of an extent to receive a climber's foot, and each of said step portions being doubled back upon itself to form an inwardly projecting end extending inwardly beyond said leg associated therewith.
Claim 2
Dependent Claim
73 words
A fence climber for use with a fence that has a wire mesh construction comprising a rod near its center bent into an approximately half-circular arc merging with two substantially equal legs each of which continues into an out-turned step portion of an extent to receive a climber's foot, and each of said step portions being doubled back upon itself to form an inwardly projecting end extending inwardly beyond said leg associated therewith.
Claim 3
Dependent Claim
32 words
A device as in claim 1 in which said half-circular arc lies in a predetermined plane and said step portions lie in a common plane at an angle to said predetermined plane.
Claim 4
Dependent Claim
39 words
A device as in claim 2 in which both rod portions adjacent said arc are straight, both rod portions adjacent said step portions are straight, and said straight parts of each rod portion are connected by intervening inclined transitions.
Claim 5
Dependent Claim
40 words
A device as in claim 1 in which said legs digress from each other as they extend away from said half-circular arc, and each of said step portions extends from the associated one of said legs at approximately ninety degrees.
