摘要： Stepladders and related methods of using and manufacturing stepladders are provided. In one embodiment, a stepladder is provided that comprises a top cap, a first assembly and a second assembly. The first assembly has a pair of spaced apart rails pivotally coupled with the top cap. The second assembly includes at least one rail pivotally coupled with the top cap. The first assembly and second assembly are configured to be displaced relative one another such that the stepladder is selectively positionable between a first, deployed state and a second, collapsed state. The first assembly, the second assembly and the top cap are cooperatively configured such that the at least one rail of the second assembly is at least partially nested within an envelope defined by the pair of spaced apart rails of the first assembly with the step ladder is in a collapsed state.

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.

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： Various embodiments of ladders, ladder legs, ladder feet, foot mechanisms for ladders, and related methods are provided herein. In one embodiment, a foot is pivotal relative to a leg or rail of the ladder between a first position and at least a second position. A biasing force is applied to the foot to maintain the foot in either of the user-selected positions until a force is applied to pivot the foot to another position. In one embodiment, the foot mechanism maintaining the foot at a desired position may include a pair of pins that couple the foot to another component (e.g., a housing member, an insert member or a rail of the ladder). At least one of the two pins may be displaceable relative to the other pin during pivoting of the foot.
