Abstract: Either frame of a telescopic stepladder comprises a support section, one or more sliding sections, a plurality of locking mechanisms each disposed in either locking portion of two sections and in one embodiment including a fastener adapted to fasten the side rail of one section and the side rail of the other section together, and a lower spring depressible detent adapted to lock both sections. Pushing the braces upward, moving both frames toward each other, unfastening the fasteners, unlocking the detents, and sliding down the sliding sections to a limit will retract the sliding sections with respect to the support sections or the retracted sliding sections.
