Modular, collapsible urban assault ladder
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.
1 . A collapsible urban assault ladder, comprising:
parallel ropes having a loop formed in each of a first end and a second end thereof;
a plurality of rungs fastened to the parallel ropes at evenly spaced intervals, each of the rungs having a longitudinal axis with a male end and a female end configured to accommodate the male end of another of the plurality of rungs, and bores formed therethrough operative to accommodate the parallel ropes transverse to the longitudinal axis and spaced apart along the longitudinal axis; and
a hook operative to engage a structural member, the hook having a bent shank with a base, legs extending laterally from the base and spaced at an angle with respect to one another, an aperture formed through the base, and an inverted L-shaped rod extending from the shank, wherein the hook is coupled to the loop formed in the first end of the parallel ropes via the aperture.
2 . The collapsible urban assault ladder of claim 1 , further comprising a carabiner engaging the loop formed in the first end of each of the parallel ropes and the aperture.
3 . The collapsible urban assault ladder of claim 1 , wherein the rungs are formed of polyvinyl chloride or carbon fiber.
4 . The collapsible urban assault ladder of claim 1 , wherein the parallel ropes are non-abrasive static ropes.
5 . The collapsible urban assault ladder of claim 1 , wherein the hook is formed of metal.
6 . The collapsible urban assault ladder of claim 1 , wherein the loop is retained by a protective sleeve.
7 . A method of surmounting a structure, comprising:
providing the collapsible urban assault ladder of claim 1 in a collapsed position;
placing the inverted L-shaped rod into the female end of a first one of the rungs;
inserting the male end of the first one of the rungs into the female end of a subsequent one of the rungs to assemble a pole;
mounting the hook onto a structure;
disassembling the pole into a scaling position; and
ascending or descending the rungs.
8 . The method of claim 7 , further comprising:
providing a second collapsible urban assault ladder after the step of providing; and
placing the second collapsible urban assault ladder hook into the loop formed in the second end of each of the parallel ropes of the collapsible urban assault ladder before mounting the hook onto the structure.
9 . The method of claim 7 , further comprising:
providing a second collapsible urban assault ladder after the step of providing; and
coupling the loops formed in the second end of each of the parallel ropes of the collapsible urban assault ladder and the second collapsible urban assault ladder.
10 . The method of claim 9 , wherein the loops are coupled by installing carabiners therethrough.
