摘要： A support frame for a folding ladder, a folding ladder positioning system, and a method for installing a folding ladder, are disclosed and pertain to folding ladders disposable within an opening, such as openings in a ceiling of a house, to provide temporary access between one floor or space and another floor or space. In one aspect, a support frame includes a plurality of separable support frame plates collectively configured to circumscribe the opening and a plurality of connection sites are disposed at opposing ends of each of the plurality of separable support frame plates to facilitate connection of each support frame plate to adjacent support frame plates. The connection sites include, for example, mating locking connectors or a plurality of matching through-holes, which permit insertion of a fastening means therethrough.

摘要： A method for setting a ladder in place includes the steps of leaning a top edge of the ladder against a work surface and swivel shoes on the bottom end of each leg of the ladder onto ground, positioning the ladder until a bubble of a rung of the ladder indicates a level reading. The method also includes the steps of sliding a rectangular closed box section metal leg having a cap which acts as a stop in an upper housing portion, the upper housing portion has two holes side by side, and a lower housing portion spaced apart from the upper housing portion of a housing of the leg attached to a rail of the ladder and inserting a holder through a hole of the two holes of the upper housing portion and a hole of two rows of holes which are set side by side but offset vertically from each other and extend through the leg.

摘要： A stanchion system, includes a stanchion post and an attachment system for attachment to a flange which includes a first edge and a second edge. The attachment system includes a crossbar including an extending section and an abutment member on a first end thereof to abut the first edge of the flange; a base including a passage through which the extending section of the crossbar is movable and a seating for the stanchion post; and a connector including a first section and a second section. The second section of the connector is attachable to the extending section of the crossbar at one of a plurality of incremental positions. The first section of the connector is movable relative to the second section to adjust the position of the first section relative to the abutment member of the crossbar. In several embodiments, the first section is movable relative to the second section to abut the base on a side of the base opposite the side upon which the flange is positioned to adjust the position of the first section relative to the abutment member.

摘要： A dynamic hinge includes a first member connected to a first ladder portion of a ladder, and a second member connected to a second ladder portion. The first member pivots relative to the second member about a pivot axis that does not intersect both the first and second members. The first member includes first and second parallel segments, and the second member includes a third and fourth parallel segments. A guide plate is attached to either the first or second member, and the guide plate is positioned between the first and second segments and between the third and fourth segments. The guide plate includes two non-linear slots, and an other of the first and second members includes two pins, respectively adapted to slide within the two non-linear slots. The pins extend between either the first and second segments or the third and fourth segments.
