Abstract
An extendable ladder with hinge brackets specifically designed for the purpose of a person to have easier and safer access to a recreational vehicle roof. RV's have a permanently attached ladder on the rear of the vehicle that has to be climbed vertically, straight up which defies gravity. The hand rails and steps are small therefore making people feel very insecure and unsafe when climbing it. This invention overcomes that obstacle by giving people a firm ladder that reaches to the ground at an angle which makes it very easy to climb. The hinge bracket design creates a pivot affect that allows the two section extendable ladder to swing out at the bottom and extend downward to the ground, then the lower ladder can slide back up into the ladder rails and is positioned back against the RV.
