A collapsible urban assault ladder includes parallel ropes; rungs fastened to the ropes at evenly spaced intervals; and a hook. The ropes have a loop formed in each end. The hook has a bent shank with a base, legs extending laterally from the base and spaced at an angle, an aperture formed through the base, and an inverted L-shaped rod extending from the shank. The hook is coupled to the loop via the aperture. Each of the rungs has a longitudinal axis with a male end and a female end, and bores to accommodate the ropes spaced apart along the longitudinal axis. A method of surmounting a structure includes placing the inverted L-shaped rod into the female end of a first rung; inserting the male end into the female end of a subsequent rung to assemble a pole; mounting the hook onto a structure; and ascending or descending the rungs.

A window frame assembly incorporating a structure for containing an emergency ladder, the ladder contained within a compartment in the lower portion of the window frame assembly. The ladder is connected directly to the structure of a building by a structural attachment, the structural attachment having connection points so that the weight of a user of the ladder is supported by the building structure. The compartment opens into the living or working area of a building, and has a removable cover. The window assembly is installed as a unit once the structural attachment is affixed to a building structural member in the bottom of the framed window opening.

This invention relates to a spreader step for a rope ladder comprising a metal scaffold having three types of overlapping elements. There are two parallel elongate elements, two U-shaped elements, the ends of which are inserted into the ends of the parallel elongate elements, and four strengthening elements that are disposed over the other two types of elements at the site of overlap.

An unmanned aerial vehicle (UAV) or manned/unmanned personal flying device (PFD) may be used to deliver a deployable descent system to an elevated location at which people await rescue, such as people trapped in an upper story of a burning building. The UAV or PFD may be used to deliver the descent system, attach the descent system to the building, and deploy the descent system. After deployment, the descent system may be tensioned to prevent sway and facilitate descent. Standoffs may be installed or integrated into the descent system to provide for adequate handholds for descending individuals. Various equipment and methods used in such systems are described herein.
