摘要： Ladders, ladder components, adjustment mechanisms and related methods are provided herein. In one embodiment, a ladder may include an adjustment mechanism for adjusting, for example, a leveler, a stabilizer, or any two relatively displaceable components of the ladder. The adjustment mechanism may include an actuating mechanism having a first structure and a second structure slidably disposed adjacent the first structure, the second structure having a plurality of engagement surfaces. A body is coupled with the first structure. At least two engagement pins are slidably displaceable relative to the body, wherein the plurality of engagement surfaces and the at least two engagement pins are arranged such that only a single engagement pin of the at least two engagement pins is in abutting engagement with an engagement surface of the plurality of engagement surfaces at one time. At least one biasing member is configured to bias the at least two engagement pins towards engagement with the engagement surfaces.

摘要： The present invention relates to ladders and, more particularly, various configurations of ladders including straight and extension ladders, as well as to methods relating to the use and manufacture of such ladders. In accordance with one embodiment of the present invention, a ladder is provided that includes a first pair of spaced apart rails and a plurality of rungs extending between and coupled to the first pair of spaced apart rails. The ladder also includes a pair of lateral support members, wherein each support member is selectively displaceable in a lateral direction relative to an associated rail. Additionally, the ladder includes a pair of adjustable legs, each leg having a first end slidably coupled to an associated rail of the first pair of spaced apart rails and being slidably coupled to an associated lateral support member.
