摘要: A stair system (20; 300) comprises: a first length-adjustable stringer (40A; 308A); a second length-adjustable stringer (40B; 308B); and a plurality of tread assemblies (148; 350) installable to the first and second stringers. The system further includes at least one handrail (268; 302A, 302B). A plurality of balusters (280A, 280B; 360, 362) are attached or attachable to the tread assemblies and handrail. The tread assemblies each have an adjustable tread pitch.

摘要: An access ladder for an access hole in a building includes a plurality of sections which telescope relative to each other between an extended position, where the sections define a plane and a user can climb the sections, and a retracted position where the sections are folded on each other. Several of the sections have a least one step which preferably moves between an unfolded position where the user can stand on the step when the sections are in the extended position, and a folded position when the sections are in the retracted position. Each section slides relative to another section of the plurality of sections which it is in contact in order for the sections to telescope. A method for using an access ladder attached to an end of an access hole of a building.

摘要: An access ladder for accessing a ceiling from a floor. The ladder comprises a plurality of sections which telescope open and closed, and from a bottom section each section telescopes open to positively lock to the section below it with plungers that lock and unlock each section in sequence as the sections open and close, respectively. A method for using an access ladder for accessing a ceiling from a floor

摘要: An access ladder includes a plurality of sections connected together to telescope between an extended position and a retracted position that has an increasing reactive force to counterbalance the weight of the sections as they extend. A method for accessing a room with a ladder connected to a ceiling including the steps of moving the ladder to a fully extended position subject to an increasingly active force to counterbalance the weight of the ladder as it extends. There is the step of retracting the ladder into a retracted position in the ceiling.

摘要: A telescopic loft ladder has two stiles with sections that are telescopically collapsible within each other, rungs having lateral ends each connected to respective sections the stiles, retractable pins in the ends of the rungs for engaging holes in the stile sections retain them in an extended position, and levers on the rungs that automatically operate when two rungs contact one another to disengage pins of the upper of the contacting rungs from the holes to permit collapse of the next higher rung. Each uppermost stile section is rotatable relative to the section connected to the uppermost rung of the ladder and has circumferentially and axially offset pin receiving holes. At least one resilient element biases the next to uppermost rung away from the uppermost rung to ensure that the locking pin of the uppermost rung engages a hole in the uppermost stile section as the ladder is lowered.
