摘要： 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. A method connects and disconnects modular carbon fiber ladder segments. Another method creates a lightweight carbon-fiber beam with exceptionally high stiffness and strength using a combination of carbon-fiber braid material, uni-directional cloth, and pultruded carbon-fiber strips. A carbon fiber ladder segment and tube connectors are also disclosed.

摘要： A ladder system is disclosed which allows for stabilizing a ladder on multiple surfaces without the need for a second person or a great deal of setup time. The collapsible ladder system includes a larger ladder section and a smaller ladder strut section which are pivotally connected at a point which is at or below the midpoint of the larger ladder section. The larger ladder section and smaller ladder strut section are connected by a rigid adjustable linkage, or spreader, at a point that is below the pivotable connection. The ladder further includes a means for stability on a variety of surfaces. At the ground contact point, the point where the ladder side rail ends and the ground meet, there are adjustable gripping feet, which can be independently or in combination vertically or angularly adjusted for maximum stability.

摘要： A portable ladder stand for supporting a hunter or naturalist above the ground includes a ladder portion, an upper assembly portion and a seat portion. The ladder portion includes a plurality of components including an intermediate ladder segment, ladder extension segment and lower ladder segment. The ladder segments are include vertical rails and horizontal rungs extending between the rails, and the segments are nestingly connected together. The vertical rails include male peg connectors and female socket connectors that are configured in such a way as to limit the number of ladder extension segments that can be included in the ladder portion of the ladder stand.

摘要： A climbing stick apparatus includes a plurality of stick members, each of which includes a fastener reception portion at each stick member end and a plurality of foot-support-reception channels. A plurality of member-to-member couplers and fasteners are provided for erecting a plurality of stick members in a longitudinal arrangement. A plurality of foot support members are received in the foot-support-reception channels. The climbing stick apparatus of the invention permits rapid assembly of a climbing stick next to a tree for hunters and other outdoorsmen. When erected next to a tree the climbing stick apparatus permits the hunter to remain above ground level so that he is not noticed or smelled by game on the ft floor.

摘要： A modular ladder assembly includes at least two ladder assemblies, each assembly having first and second parallel stiles and a plurality of spaced apart rungs disposed between the first and second stiles, the plurality of rungs being perpendicular to said first and second stiles. The first stiles of the at least two ladder assemblies are mechanically connected together and at least one adjustment assembly is mechanically connected to the second stile of one of the at least two ladder assemblies and a second end of at least one adjustment assembly is mechanically connected to a second stile of a second of the at least two ladder assemblies so that the at least two ladder assemblies and the at least one adjustment assembly have a triangular shape when viewed from a plane perpendicular to the first and second stiles of the at least two ladder assemblies.

摘要： A segmented ladder is provided that can be assembled in minutes into specific lengths of straight ladders and configured into a free standing step ladder for easy handling and selection of the proper length required for the specific work application wherein the side rails are of lightweight tubular aluminum construction and are of uniform size and parallel with each other and with the lightweight aluminum rungs permanently affixed between the side rails with the interconnections between the segments being accomplished at each side rail by a telescopic joint containing both a male and female section utilizing integral spring loaded steel detents that are activated by finger pressure when the telescopic joints are mated and are located in positional holes directionally located in the male section of the joints which engage matching holes in the female section of the joints when the joints are telescoped together thus locking the segmented sections together into either specific straight ladder lengths or a free standing step ladder with the bottom most segmented ladder section containing integral support rubber feet located in the bottom of the side rails and the bottom of the back brace segments and the top most segmented ladder section containing an integral rubber cap located on the top of the side rails to prevent marring any surface against which the ladder may be placed with disassembly of the ladder being accomplished in a reverse manner to the assembly by pressing-in the detents using finger pressure and sliding the telescopic joints apart thus providing a shorter more compact over-all packageable configuration which provides more convenient and secure storage.
