  • Patent number: 4263983
    Abstract: A portable, multisectional ladder for scaling poles, trees and like objects and a method of use thereof. Individual ladder sections are formed of steps welded to individual angle metal sections. The angle metal sections are removably joined using male/female connectors at either end thereof. One or more brackets welded to each section slidably retains an auto-type safety belt which can be releasably buckled about the object to be scaled. The brackets on each section except for the base section include a special belt cincher arrangement which includes means for drawing the belt into the recessed portion of the angle metal to forcibly tighten the belt about the object to be climbed, thereby eliminating any slippage or wobble in the ladder.
