US 2021/0340816 A1 · Ladder Safety Post Assembly

Abstract

A ladder safety post assembly is an apparatus that enables the user to safely climb in and out of manholes using the sunken ladders provided within. The apparatus may include an elongated housing, a threaded shaft, a hand wheel, a stationary rung hook, and a movable rung hook. The elongated housing provides a third point of contact for the user to hold onto when initially descending into the manhole or when coming out of the manhole. The threaded shaft enables the movement of the movable rung hook to secure the movable rung hook against a ladder rung. The hand wheel enables the user to manually rotate the threaded shaft to adjust the position of the movable rung hook along the threaded shaft. The stationary rung hook and the movable rung hook both secure the elongated housing to the sunken ladder by grabbing onto adjacent ladder rungs in a jaw-like manner.
