  • Extensible ladder
    Patent number: 5738186
    Abstract: An extensible ladder includes a plurality of sections, each having a pair of tubular uprights connected by a rung, with the uprights of each section being slidably engaged with the corresponding uprights of an adjacent section. The inside surface of the tubular uprights are provided with longitudinally extending grooves, which reduce the area of sliding contact between adjacent uprights, thereby making the ladder easier to extend or collapse.
