Abstract:
A ladder leveling system comprising:a ladder having a pair of side rails and a plurality of rungs extending between said side rails; each of said rails having an associated hollow interior defined by a plurality of walls, each of said rails having an inner wall positioned toward said rungs such that said rungs are mounted on said inner walls of said rails, each of said rails having an outer wall located opposite said inner wall; a pair of solid legs, each solid leg having an associated connection portion slidably inserted into a respective bottom of an associated one of said hollow interiors such that each said solid leg is positioned to extend downwardly out of said associated one of said side rails; each said connection portion having an associated plurality of leg teeth on a first face of said associated connection portion, said first face of each said connection portion being located adjacent to said inner wall of said associated one of said side rails; each said hollow interior of each said side rail having an associated interior face on said inner wall, each interior face on said inner wall having an associated plurality of rail teeth, each said plurality of rail teeth being for matingly receiving an associated one of said pluralities of leg teeth; a plurality of clamping members, each clamping member being coupled to said outer wall of an associated one of said side rails, each said clamping member being selectively extendable into said hollow interior of said associated one of said side rails for urging said associated leg teeth into engagement with said associated rail teeth whereby said associated solid leg is held in a static position relative to said associated one of said side rails; a rung level coupled to a lowermost one of said plurality of rungs for facilitatingly positioning of said ladder such that said rungs are in a substantially horizontal orientation during use of said ladder; a rail level coupled to one of said side rails; a pair of foot members, each foot member being pivotally coupled to a bottom of an associated one of said legs; each said clamping member having an associated threaded rod portion extending from an associated head portion; each of said side rails including an associated threaded aperture extending through an associated outer wall of said associated one of said side rails; each said threaded rod portion of said associated clamping member being threadedly insertable through said associated threaded aperture whereby rotating said associated head portion selectively extends and retracts a distal end of said associated threaded rod portion in said associated hollow interior of said associated one of said side rails; and each said clamping member having a generally cross shaped associated head portion for facilitating gripping of said associated head portion for rotating said associated head portion.
