A retro-fit installation modifies the existing pool ladder structure of an existing in-ground or above-ground swimming pool to support an underwater swim out platform structure. In some versions, the ladder rails of the existing pool ladder are used to support the underwater platform, while in others the existing pool ladder rails are replaced with new tubular platform rails specifically designed to support the underwater platform structure. Other versions are adapted for installations in a round pool or at a corner of a rectangular pool.

An adjustable ladder and stair system has a folding stair assembly including a ladder-member having a first-end, a second-end, a plurality of rungs equidistantly spaced between a first-rail and a second-rail, and a securer, a stair-member having a stair-portion, a first-rail-slide-mechanism, a second-rail-slide-mechanism, a first-rail-locking-mechanism, and a second-rail-locking-mechanism. The ladder-member may be secured in a vertical position parallel to a substantially vertical item desired to be ascended via the securer. The stair-member is adjustable to accommodate a desired angle. The folding stair assembly provides an apparatus for safely accessing a substantially vertical item desired to be ascended such as a roll off garbage bins.

The invention relates to a ladder system for trench shoring, comprising a lower ladder (14) which extends from the bottom of a trench over a lower subportion (T1) of the height of the trench, and an upper ladder (16) which extends over an upper subportion (T2) of the height of the trench up to a trench edge, wherein the upper ladder (16) is a suspension ladder for suspending onto a shoring panel (12). A ladder system according to the invention is intended to increase the safety of the workers particularly for deep trenches. In a ladder system according to the invention, a platform (22) is arranged at the lower end of the upper ladder (16) is, and that the lower ladder (14) is a stepladder or leaning ladder which stands on the bottom of the trench.

A safety apparatus for coupling with a ladder and methods for manufacturing and using same. The safety apparatus includes an engagement member defining an engagement member recess for receiving a selected structure and a retention member rotatable relative to the engagement member such that the retention member extends distally from the engagement member in an open position and extends proximally to the engagement member in a closed position. The retention member transitions from the open position to the closed position for enclosing the selected structure within the engagement member recess when weight is applied to the ladder and transitions from the closed position to the open position for releasing the selected structure when the weight is removed from the ladder. The ladder advantageously can inhibit unexpectedly detachment from the selected structure during use and does not require manual disengagement of the selected structure after use is complete.

A safety apparatus for coupling with a ladder and methods for manufacturing and using same. The safety apparatus includes a first engagement member for coupling with a first rail of a ladder and defining a first engagement member recess and a second engagement member for coupling with a second rail of the ladder and defining a second engagement member recess. A third engagement member can couple with the first and second rails and be rotatable between a first position for engaging a first support structure and a second position for at least partially enclosing a second support structure within the first and second engagement member recesses. The safety apparatus advantageously can alternatively engage horizontal support structures or vertical support structures to prevent falls.

A convertible folding ladder incorporates first and second rigid ladder sections, each comprising opposing spaced apart longitudinal rails, a plurality of spaced apart rungs between the rails, and a connector plate formed with one end of at least one of the longitudinal rails. Each connector plate of the first ladder section defines at least three spaced apart pin holes adapted for being selectively aligned with pin holes defined by the connector plate of the second ladder section. First and second fastener pins are adapted for being removably inserted through the aligned pin holes, such that the ladder is convertible between multiple different configurations.

An apparatus and method for supporting a ladder on a roof having a ridge is disclosed herein. The apparatus includes a frame, a roof anchor, a first ladder engagement portion, a second ladder engagement portion and a wheel assembly. The first ladder engagement portion and the second ladder engagement portion attach the apparatus to the ladder. The wheel assembly enables the apparatus to be easily rolled up and down the roof and the roof anchor anchors the apparatus over the ridge of the roof to attach the apparatus, and thus the ladder, to the roof.
