ADJUSTABLE LADDERS, LADDER COMPONENTS AND RELATED METHODS

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.

1. A ladder comprising:
a first rail assembly comprising:
a pair of inner rails and a pair of outer rails, the pair of inner rails being slidably disposed in a upper portion of pair of outer rails,a first plurality of rungs coupled between the pair of inner rails,a second plurality of rungs coupled between the pair of outer rails, a pair of leveler mechanisms, each leveler mechanism associated with one of the pair of outer rails,
each leveler mechanism comprising:a leg member slidably disposed within a lower portion of its associated outer rail;an actuating mechanism configured to enable longitudinal movement in an a first direction and a second, opposite direction when actuated, but allow movement in only the first direction when not actuated;a spring to maintain a biasing force on the leg member in the second direction.
