摘要： An extendable and retractable ladder which comprises a plurality of ladder sections, each of which is stackable upon and nestable within the adjacent ladder section. A locking means is disposed between adjacent ladder sections to lock relative installation positions of the ladder sections. The locking means is disposed in a middle portion of the rung of the ladder section and it comprises a left and a right locking rods which move in synchrony with each other, a spring which connects the left and the right locking rods, and a left and a right controlling handles which are connected to the left and the right locking rods respectively. Locking holes are disposed on adjacent ladder sections and free ends of the left and the right locking rods at corresponding positions. As only one single hand is required to simultaneously pull the left and the right controlling handles to unlock the ladder sections, the present invention is more convenient to use.

摘要： The invention relates to an arrangement for a fixation, which is applied to a ladder. The ladder shows at least one hollow rung. A bolt is located longitudinally and inside the hollow rung. The bolt shows at its first side an eye, which is used as attachment-point for attachment-purposes, while the eye is located outside the hollow rung on a first side of the ladder. The bolt shows at its second side an interlock, which can be engaged at a second side of the ladder firmly but detachably, so a movable attachment-point is originated at the ladder by the hollow-rung, by the inserted bolt and by the eye and the interlock, which are connected with the bolt.

摘要： Extending ladders and associated manufacturing methods are disclosed. A ladder in accordance with an exemplary embodiment of the present invention comprises a plurality of rung units, each rung unit including a left column, a right column, and a rung extending between the left column and the right column. The ladder may include a first column assembly including a first column and a ring coupled to the first column proximate a distal end thereof, and a second column assembly including a second column and a sleeve coupled to the second column proximate a proximal end thereof. The second column being at least partially disposed within a lumen defined by an internal surface of the first column. The sleeve includes an external guiding surface for contacting the internal surface of the first column and the ring includes an internal guiding surface for contacting an exterior surface of the second column.
