  • Ladder assist wheel
    Patent number: 6585084
    Abstract: A ladder assist wheel attached to the outer face of one of the ladder side rails. The wheel extends out from the outer face and rotates on an axis that is parallel to the plane of the outer face. A reinforcing plate is placed in contact with the inner face of the side rail and is operably attached to the wheel. The wheel is preferably positioned adjacent the bottom end of the side rail so that the ladder may be transported on its side by grasping the top end with one hand and allowing the wheel to contact and roll along the ground. For dual access folding stepladders, a wheel is attached to each of the side rails on one side of the ladder.
