Abstract: A ladder may include a first pair of spaced apart members, a second pair of spaced apart members and a first pair of hinges coupling the first pair of spaced apart members with the second pair of spaced apart members. In some embodiments, each hinge may include a first hinge component including at least a first hinge plate, the first hinge plate having a notch formed therein, the notch including a first abutment wall and a second abutment wall, a second hinge component including at least a second hinge plate, and a lock mechanism having a pivot pin and a lock pin. The lock mechanism is configured for selective engagement with the notch such that the pivot pin engages the first abutment wall and the lock pin engages the second abutment wall to lock the first hinge component relative to the second hinge component in a first hinge position.

Abstract: Ladder configurations and components are provided including a first assembly of rails and a second assembly of rails that are pivotable relative to each other between a collapsed configuration and an expanded configuration. A handle coupled to a rail extends inward from the rail and has an inner end resiliently deflectable between a clearance position and a weight bearing position that engages another rail as the ladder is carried by the handle. A spreader mechanism includes a platform extending between jointed linkages and that extends the top surface of a rung coupled to two of the rails. An inner end of the platform may be used as a handle to expand or collapse the ladder. The platform may be extruded and assembled with the rung in a manner limiting pinching or gaps at an interface between the platform and the rung.

Abstract: An interlocking ladder system for transporting at least two ladders which are stacked together. The ladder system includes a first ladder having a first end cap having a cap portion and an engagement portion with a slot, a second ladder having a second end cap having a cap portion and an engagement portion with a slot, and preferably a third end cap having a cap portion and an engagement portion with a slot. The slot of the engagement portion of the second end cap engages with the slot of the engagement portion of the first end cap when the second ladder is stacked on top of the first ladder. The ladder system may include a third ladder having a fourth end cap having a cap portion and an engagement portion and a slot. The slot of the engagement portion of the third end cap engages with the slot of the engagement portion of the fourth end cap when the third ladder is stacked on top of the second ladder. The second ladder stacked on top of the first ladder and preferably the third ladder stacked on top of the second ladder all together form a stack. A method for stacking ladders into a stack.

Abstract: A tripod assembly includes a plurality of columns disposed in a nested arrangement for relative axial movement in a telescopic fashion along a longitudinal axis of the plurality of columns between a fully-extended position and a collapsed position. When the columns are collapsed from the fully-extended position each column substantially nests within another one of the columns. The plurality of columns are received within the central post when the plurality of columns is in the collapsed position. The bracket assembly is coupled to the second end of the connecting rod, and the bracket assembly is configured to receive a selectable rung of a ladder therein. The bracket member is coupled to an uppermost one of the columns, and the bracket member includes a channel configured to receive a second selectable rung of the ladder.

Abstract: A ladder and ladder accessory are provided including an accessory that may be coupled to the ladder in multiple configurations and serve multiple purposes. In one embodiment, a pair of components are each selectively coupled with associated rails of a ladder in a first, stored state, and a second, walkthrough state. When in the walkthrough state, the components extend upwards from and above the rails so that a user may gasp the components and step between the components when transitioning from the ladder to an elevated surface (e.g., a roof) or vice versa. In another embodiment, the components may be coupled to the ladder such that they extend in a direction that is substantially transverse to a plane through which the rails extend. When in this transverse orientation, the components may be used as a stand-off device.
