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.

First claim

What is claimed is:

1. An accessory for a ladder comprising:
at least one arm;
at least one bracket coupled with the at least one arm;
a locking mechanism associated with the at least one bracket, the locking mechanism including:
a first member positioned on a first side of the at least one arm,
a second member positioned on a second opposing side of the at least one arm,
a lock pin pivotally coupled with the first and second members, the lock pin extending through a first portion and a second portion of the at least one arm,
a biasing member positioned about a portion of the lock pin and biasing the lock pin in a first direction,
wherein, when the first and second members are displaced towards each other, the lock pin is displaced in a second direction, opposite the first direction.

2. The accessory of claim 1 , wherein the at least one arm includes a first arm and a second arm telescopingly coupled with the first arm.

3. The accessory of claim 1 , further comprising an end member pivotally coupled with the at least one arm.

4. The accessory of claim 3 , further comprising a second locking mechanism configured to selectively lock the end member in a first position and at least a second position relative to the at least one arm.

5. The accessory of claim 4 , wherein, when in the first position, the end member extends longitudinally outward from the at least one arm, and wherein, when in the at least a second position, the end member extends at an angle of substantially 90 degrees relative to a length of the at least one arm.
