LADDER STABILIZING DEVICE

摘要

A stabilizing device to be connected on the outer sides of the side pieces of a ladder has a lower leg pivoted on a lower part of the side piece and pivoted at its upper end to an upper leg part. The pivotal knee between the upper and lower leg parts may be braced against the ground or against a vertical wall surface. A lever on the upper leg part has a dog which reacts against a toothed rack on the ladder and lifts the ladder bodily a small distance, transferring the weight of the ladder to the outlying leg parts.
