Claim Text:
1. An adjustable ladder attachment configured to be secured to a vehicle to enhance user stability and safety when servicing the vehicle, the ladder attachment comprising: an outer ladder assembly comprising a pair of rails oriented parallel to one another and connected by a plurality of steps; an inner ladder assembly comprising a pair of rails oriented parallel to one another and connected by a plurality of steps, the inner ladder assembly rails being slidably mounted to the outer ladder assembly rails to one of a plurality of locking positions; a platform pivotably mounted to a top portion of the inner ladder assembly and comprising a front edge, a rear edge opposite the front edge, and a pair of side edges extending between the front and rear edges, the rear edge being on a rear portion of the platform directly coupled to the inner ladder assembly; a generally rectangular plate pivotably mounted to the front edge of the platform and comprising a front edge, a rear edge opposite the front edge of the plate and directly coupled to the platform, and side edges extending between the front and rear edges of the plate; a lock bracket rotatably mounted to a bottom portion of the platform and comprising a pair of C-brackets, the first C-bracket of the pair of C-brackets being directly coupled to the platform, the second C-bracket of the pair of C-brackets rotatably mounted to the first C-bracket, wherein the second C-bracket is configured to rotatably adjust relative to the first C-bracket to a first position to create an opening sufficient to receive the front edge of the rectangular plate after a pivotal adjustment of the plate, wherein the second C-bracket is configured to rotatably adjust relative to the first C-bracket to a second position to secure the front edge of the rectangular plate in a locked position within the pair of C-brackets; wherein the outer ladder assembly is configured to be positioned on a ground surface proximate the vehicle and the platform is configured to pivotably adjust to rest on top of a tire of the vehicle, wherein the second C-bracket of the lock bracket is configured to rotatably adjust to the first position to permit the rectangular plate to pivot away from the pair of C-brackets until a face of the plate rests against an inner edge of the tire, thereby enabling a user to stand on the platform or the steps of the ladder assemblies.
