A pool ladder may have a first and second leg extension, each having a generally continuous profile; a first tread may comprise first and second through-holes, the first through-hole being sized to slidingly receive the generally continuous profile of the first leg extension, and the second through-hole being sized to slidingly receive the generally continuous profile of the second leg extension; and a first and second tread support. The first tread support may be engaged at a tread location on the first leg extension and may be separate from the first leg extension. The second tread support may be engaged at a tread location on the second leg extension and may be separate from the second leg extension. Each of the first and second tread supports may protrude from the respective leg extension a sufficient amount to prevent the first and second through-holes from sliding past the tread locations.

An extendable/retractable ladder assembly includes a first stile and a second stile and a plurality of rungs extending therebetween. Each stile may comprise a plurality of columns disposed in a nested arrangement for relative axial movement in a telescopic fashion. A connector assembly connects the rungs to respective columns in the first and second stiles. The ladder has improved manufacturability since connector assemblies may be assembled before connecting the rungs to respective columns. The standing surface of the rungs may be angled such that it is rotated towards horizontal when the ladder assembly is leaned against a wall. A latch assembly may be used to selectively lock relative axial movement between adjacent columns. The latch assembly includes a locking pin assembly comprised of a central post and an outer metal sleeve. An air damper may also be used to control airflow through the columns.

Embodiments include a telescoping ladder with a plurality of columns and rungs. The ladder can have a plurality of locking assemblies for locking adjacent columns to a rung thereby restricting relative sliding motion between adjacent columns. The locking assembly can have a locking button positionable against the rung front surface and rotatable with respect thereto between a locked position and an unlocked position. The locking assembly can have a locking pin positioned within the rung and slidable between an extended position and a retracted position along a locking pin axis generally perpendicular to the rotational axis. The locking assembly can have a connector pin extending in a direction parallel to the rotational axis, for connecting the locking button to the locking pin such that rotation of the locking button about the rotational axis slides the locking pin about the locking pin axis.

An adjustable-height ladder includes left and right legs and a series of horizontal steps coupled to the left and right legs. The ladder also includes a utility tray.

A ladder having a first rail and a second rail. The ladder having a standard rung having a width permanently attached to the first rail and the second rail. The ladder having a first wide rung having a width greater than the width of the standard rung, which is permanently attached to the first rail and the second rail. The ladder having a second wide rung having a width greater than the width of the standard rung, which is permanently attached to the first rail and the second rail. The first wide rung and the second wide rung are disposed in a work zone of the ladder. The work zone of the ladder is where a user typically stands on the ladder while performing tasks. The standard rung is disposed outside the work zone. A wide rung. A method for using a ladder. A method for producing a ladder.

A rung mounting structure used for a ladder includes supporting legs, a rung and a connecting plate, wherein upper ends of the two supporting legs are connected through the connecting plate, the rung is arranged between the supporting legs, the supporting legs are made of metal sections, concave parts are arranged on inner sides of the supporting legs and each are provided with an opening allowing the rung to be inserted therein, and the sides, opposite to the openings, of the concave parts are sealed; and after the rung is inserted into the concave parts, the rung and the supporting legs are circumferentially limited and are fixedly connected.

An intermediate rung apparatus for use with a ladder includes a first hook, legs, and an intermediate rung. The first hook is configured to extend over a rung of the ladder and couple the intermediate rung apparatus to the ladder. The intermediate rung apparatus also includes legs extending from the first hook. The legs are configured to extend in a downward direction substantially parallel to vertical supports of the ladder when the intermediate rung apparatus is coupled to the ladder. The intermediate rung apparatus further includes an intermediate rung connected to the legs and configured to extend in a direction substantially parallel to the rung of the ladder when the intermediate rung apparatus is coupled to the ladder. In some embodiments, a mount may be used to support the intermediate rung apparatus and/or the ladder.
