Abstract: Ladders, ladder components and related methods are provided including various embodiments of a combination ladder. In some embodiments, a platform is provided that is fixedly coupled with a rail assembly of a combination ladder. The platform may pivot between a useable position or state and a stowed or stored position or state. The platform may maintain a position relative to certain rungs of the rail assembly while being displaceable relative to other rungs of the rail assembly. A hand rail may be coupled to the rail assembly and a tray may be coupled with the hand rail. The tray and the platform may be configured to maintain a constant distance between one another while the rail assembly is adjusted for height.

Abstract: 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.

Abstract: A combination tree stand and hand truck are herein disclosed, comprising a seat mounted on the bottom of a conventional wheeled hand truck. The rear of the hand truck comprises a plurality of cross members and is attached via a pair of hinges to an additional section of a ladder like structure that is capable of being foldable extended to form a ladder. In use, the wheeled hand truck may be used to transport items to and from a hunting location. Once at a hunting location, the hand truck may be converted into a tree stand by deploying the folding ladder section and placing the deployed stand upside down against a tree or other structure therewith a securing means. The apparatus is particularly useful in game lands and other restricted hunting areas where an all-terrain vehicle or other motorized vehicle is not permitted.

Abstract: 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.

Abstract: A modular ladder system is provided, wherein segments may be joined without limit to form a ladder of any desired length.

Abstract: An add-on extension ladder is removably mountable to a portion of a conventional ladder to extend the reach of the conventional ladder without any structural modification to the conventional ladder. The add-on extension has integral elements for engaging rungs on the upper portion of the conventional ladder to easily mount and remove the extension ladder to and from the conventional ladder.
