Abstract
Ladders, ladder components and related methods are provided including various embodiments of a combination ladder. In some embodiments, a platform is provided that is fixedly coupled with a rail assembly of a combination ladder. The platform may pivot between a useable position or state and a stowed or stored position or state. The platform may maintain a position relative to certain rungs of the rail assembly while being displaceable relative to other rungs of the rail assembly. A hand rail may be coupled to the rail assembly and a tray may be coupled with the hand rail. The tray and the platform may be configured to maintain a constant distance between one another while the rail assembly is adjusted for height.

23. A method of adjusting a ladder, the method comprising:
-
providing a first rail assembly having a pair of inner rails with a plurality of rungs coupled therebetween and a pair of outer rails having a plurality of rungs coupled therebetween, the pair of inner rails being slidably coupled with the pair of outer rails; providing a second rail assembly having a pair of inner rails with a plurality of rungs coupled therebetween and a pair of outer rails having a plurality of rungs coupled therebetween, the pair of inner rails being slidably coupled with the pair of outer rails; positioning the first rail assembly at an acute angle relative to the second rail assembly to provide a self-supporting ladder; fixedly coupling a platform with the first rail assembly and orienting a body portion of the platform in a first position suitable for a user to stand on; displacing the pair of inner rails of the first rail assembly relative to the outer rails of the first rail assembly while maintaining the platform at a constant position relative to at least one rung of the plurality of rungs coupled between the inner rails of the first rail assembly. - View Dependent Claims (24, 25, 26, 27, 28)
