<p>A device for supporting a person on a ladder in which a frame is provided for extending around the ladder with sufficient clearance to move relative to said ladder. A portion of the frame extends at an angle relative to the remaining frame and inwardly towards the ladder. The frame can be connected to the person at a position that of said angularly-extending portion so that movement of the person downwardly on said ladder causes said angularly-extending portion to move between the ladder stays and engage a rung on said ladder to prevent further downward movement.</p> |
