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.

A safety ladder for mounting between a support surface and a ground surface includes two support assemblies and parallel step members pivoted between the support assemblies. Each support assembly includes first and second support rods each having upper and lower ends. The upper ends of the first support rods of the support assemblies are configured to be pivoted to the support surface. The safety ladder is movable between a use position, in which the lower ends of the first and second support rods of the support assemblies are adapted to simultaneously contact the ground surface, and a storage position, in which the first and second support rods stand substantially perpendicular relative to the ground surface.

A ladder and ladder accessory are provided including an accessory that may be coupled to the ladder in multiple configurations and serve multiple purposes. In one embodiment, a pair of components are each selectively coupled with associated rails of a ladder in a first, stored state, and a second, walkthrough state. When in the walkthrough state, the components extend upwards from and above the rails so that a user may gasp the components and step between the components when transitioning from the ladder to an elevated surface (e.g., a roof) or vice versa. In another embodiment, the components may be coupled to the ladder such that they extend in a direction that is substantially transverse to a plane through which the rails extend. When in this transverse orientation, the components may be used as a stand-off device.

A collapsible ladder that collapse not only the rails but also the steps, as well as the top caps, so that the ladder may be erected and then collapsed flat, saving storage space. The ladder has a pair of right siderails rotatably connected to a pair of left siderails. The right top cap and the right steps are rotatably attached in between the pair of right siderails. The right top cap and the right steps are also rotatably attached in between the pair of right linking rails. Likewise, the ladder also has a pair of left siderails rotatably connected to a pair of left siderails. The left top cap and the left steps are rotatably attached in between the pair of left siderails. The left top cap and the left steps are also rotatably attached in between the pair of left linking rails. Because the siderails, the steps, the linking rails are all rotatably attached to form the ladder, the ladder may be open and erected and also may be folded and collapsed to save space for storage and for carrying.

A convertible ramp system facilitates transfer of personnel between spaced elevations. The ramp system includes a deck assembly, a convertible main ramp, and a convertible extension ramp. The convertible main ramp has a proximal end hinged to the deck assembly and a distal end adapted for being mechanically lifted and lowered relative to the deck assembly. Both the main ramp and the extension ramp incorporates an adjustable frame assembly and a series of simultaneously articulating foot treads carried by the frame assembly. The ramps are selectively convertible between a stairway configuration and a substantially flat and continuous runway configuration.

A step iron for a concrete structure, the step iron comprising a body and a leg; the body and leg each comprising a metal core and at least partially encapsulated in a polymer material; the body comprising a tread length to enable a user to use the step iron for climbing; the leg comprising a proximal end nearer the body and a distal end; the distal end of the leg comprising an end section to abut a complementary section of an insert which is fixable and embeddable within a concrete structure; a fixing means mounted on the leg to enable reversible engagement with a complementary section of the insert.

A storage rack post step for use with a storage rack post, the storage rack post comprising a plurality of storage rack post holes, includes a body. The body has a step surface, a support surface configured to abut the storage rack post, a locating boss extending from the support surface and configured to be received by a storage rack post hole, and a bore extending through the support surface and the locating boss. The storage rack post step also includes a fastener configured to extend through the plurality of storage rack post holes and the bore and clampingly secure the storage rack post step to the storage rack post.
