Walkthrough and standoff mechanisms for ladders, ladders incorporating same and related methods
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.
Ladder Stabilizer Attachment Device
A ladder stabilizer attachment device secures a ladder stabilizer to a ladder. The device includes a sleeve including an outer wall. The outer wall has an outer face, an inner face, an upper end, and a lower end. The lower end is open. A slot extends into the inner face from the lower end to receive a top end of a ladder side rail and an uppermost rung of the ladder into the slot. A top edge of the slot defines a stop whereby the stop rests upon the uppermost rung of the ladder. A coupler is mounted to the sleeve. The coupler releasably engages the uppermost rung of the ladder.
Ladders, ladder components and related methods
Ladders, ladder components and related methods are provided. In some embodiments, adjustable stepladders are provided which include locking mechanisms that enable height adjustment of the ladder through application of a force towards the rails of the ladder. In other embodiments, spreader mechanisms are provided with cross bracing located and configured to provide additional stability to the ladder while also incorporating a handle that enables efficient collapsing of the ladder while reducing the potential of pinching ones hands or fingers. In another embodiment, a device is provided for selective coupling with the ladder that includes a support or safety rail and an adjustable tray. The device may be coupled with the ladder in a number of different positions including a stowed position. In another embodiment, a hinge assembly is provided having a magnetic component configured to be magnetically coupled with and temporarily store an object on the ladder.
Ladder leveling and stabilizing assembly
The assembly includes a first arcuate tube attached to a ladder. A second arcuate tube is slidably disposed in the first arcuate tube. A lock subassembly is disposed on the first arcuate tube for limiting movement of the second arcuate tube relative to the first arcuate tube. A step lever extends along the first arcuate tube and is coupled with the lock subassembly. A first flange and a second flange each extend radially from the first arcuate tube. An actuating member defines a cam surface abutting the second flange. A bar extends through the flanges and attaches to the actuating member. The step lever attaches to the actuating member to move the actuating member and cause the cam surface to slightly deform the first arcuate tube about the second arcuate tube and engage the second arcuate tube. A foot is pivotably disposed at each end of the second arcuate tube.

Apparatus and Method for Stabilizing a Ladder
A device is for securing a ladder against falling to one side. The device has a first reel and a second reel. The first reel has a first elongated, flexible connecting means arranged to be run to an anchor via one end portion of the ladder. The second reel has a second elongated, flexible connecting means arranged to be run to an anchor via the second end portion of the ladder. A locking mechanism is for locking the elongated flexible connecting means. The device is mountable on the ladder in such a way that, in a position of use, the locking mechanism is accessible from one end portion of the ladder. A ladder mounted with the device and a method is for securing the ladder against falling to one side.

Three Section Extension Ladder and Method
An extension ladder including a base section and an intermediate fly section. The intermediate fly section slidably attached to the base section. The extension ladder including a top fly section. The top fly section sliding attached to the intermediate fly. The extension ladder including a handle having a first strap portion attached to the base section having a first buckle portion, and a second strap portion attached to the top fly section having a second buckle portion that engages with the first buckle portion when the base section, intermediate fly section and top fly section are in a folded state where they essentially form a shape of a cube so the base section, intermediate fly section and top fly section can be lifted by the handle. The present invention pertains to a method of moving an extension ladder.
