Abstract: Ladders and ladder components are provided including a rung assembly that provides an alert to a user of the ladder that they are standing on a particular rung or step. In one example, the lower most rung or step of a ladder includes a rung assembly having an alert mechanism. The alert mechanism may provide an audible and/or other sensory alert to a user when they step on the rung assembly so that the user recognizes their position relative to the ground or supporting surface. In one embodiment, the rung assembly is configured such that a front edge remains in a constant or fixed position relative to the rails to which it is coupled so that a user can rely on a fixed or constant position of the front edge of the assembly when climbing or descending the ladder.

Abstract: A system may include an enclosure base having a bottom surface and one or more side walls coupled with the bottom surface. A system may include an enclosure lid having a top surface, the enclosure lid coupling with the one or more side walls of the enclosure base to create an enclosed space, the enclosed space containing a massive flywheel, the massive flywheel having one or more axles. A system may include one or more bearings coupling the one or more axles to the enclosure base and the enclosure lid, the one or more bearings holding the one or more axles at an axis of rotation. Aspects of the invention include components coupled with the system, such as a vacuum assembly, adjustment and locking mechanisms, and other components.

Abstract: A system may include a massive flywheel including a rotatable mass component and one or more axles coupled with the rotatable mass component. A system may include a magnetic lift component having one or more magnets positioned around a center perforation, the one or more axles passing through the center perforation in the magnetic lift component, the one or more magnets pulling the massive flywheel toward the magnetic lift component. A system may include a support structure coupled with the magnetic lift component, the support structure holding the magnetic lift component at a stationary location relative to the support structure. A system may include one or more bearings coupled with the support structure and the one or more axles to maintain the one or more axles at an axis of rotation.

Abstract: A ladder is provided having a base section and a fly section slidably coupled with the base section. The base section includes a first pair of spaced apart rails and a first plurality of rungs extending between and coupled to the first pair of spaced apart rails. The fly section includes a second pair of spaced apart rails and a second plurality of rungs extending between and coupled to the second pair of spaced apart rails. The various rungs may be coupled with their associated rails in an offset relationship such that they are not centered along a longitudinal center axis line of the rails. A rung lock device may be used which includes an arm pivotally coupled with the base section and configured to selectively engage various rungs of the second plurality of rungs to maintain the fly section in a desired position relative to the base section.

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.
