Ultra Lightweight Segmented Ladder/Bridge System Accessories
A dual-use ladder and bridge modular system preferably includes tubes, gussets, flanges, and/or joints. In a preferred embodiment, the tubes, gussets, flanges, and/or joints are made of carbon fiber. In one embodiment, a removable platform converts the segmented ladder system into a bus assault ladder/platform. Another preferred embodiment includes a bridge conversion kit. Yet another preferred embodiment includes a stretcher cover. When none of the bus assault platform, the bridge conversion kit, or the stretcher cover are needed, the ladder can be used as normal, or stored in a carry bag.

26 . A modular stretcher comprising:
a) at least two ladder segments, wherein each ladder segment comprises:
i) a pair of carbon fiber tubes forming a pair of tubular carbon fiber side rails, each carbon fiber side rail having a first side rail end and a second side rail end; and
ii) at least one carbon fiber rung perpendicular to the carbon fiber side rails, wherein the carbon fiber rung connects the carbon fiber side rails of the ladder segment;
b) a joint connector located at at least one of the first end and the second end of each carbon fiber side rail; and
c) a stretcher cover;
wherein the joint connector on an end of the first carbon fiber side rail of a first ladder segment is shaped to fit inside the carbon fiber side rail of an adjoining ladder segment or mates with the joint connector on the second carbon fiber side rail of a second ladder segment; and
wherein the stretcher cover is secured to the ladder segments.
27 . The modular stretcher of claim 26 , wherein the stretcher is secured to the ladder segments using a plurality of straps or rope.
28 . The modular stretcher of claim 26 , further comprising a plurality of straps for securing a person to the modular stretcher.
29 . The modular stretcher of claim 26 , wherein the carbon fiber side rails or the carbon fiber rung comprises:
a) an inner carbon fiber layer;
b) an outer carbon fiber layer; and
c) a plurality of carbon fiber strips sandwiched between the inner carbon fiber layer and the outer carbon fiber layer.
30 . The modular stretcher of claim 26 , wherein the carbon fiber side rails or the carbon fiber rung comprises:
a) an inner carbon fiber layer;
b) an outer carbon fiber layer; and
c) a layer of uni-directional carbon fiber material surrounding the inner carbon fiber layer.
31 . The modular stretcher of claim 26 , wherein the carbon fiber side rails or the carbon fiber rung comprises:
a) an inner carbon fiber layer; and
b) an outer carbon fiber layer; and
wherein at least one of the inner and outer carbon fiber layers comprises a braided carbon fiber material.
32 . The modular stretcher of claim 31 , further comprising at least one layer of uni-directional carbon fiber material placed between the inner carbon fiber layer and the outer carbon fiber layer.
33 . The modular stretcher of claim 26 , wherein at least one of the carbon fiber side rails and the carbon fiber rung is filled with a core material.
34 . The modular stretcher of claim 26 , wherein a portion of the rung is located inside each of the carbon fiber side rails and is bonded to an interior of each carbon fiber side rail.
35 . The modular stretcher of claim 26 , further comprising a flange on each side of the rung that matches a contour of the rung.
