Abstract: A quick release ladder accessory attachment system is provided. In one embodiment, a ladder system includes a rail having an end and a body, and a ladder-accessory mount operable to releasably attach a ladder accessory to the body of the rail with only one's hand. The ladder-accessory mount includes one or more slots disposed in the body of the rail and operable to receive a corresponding protrusion of a ladder accessory. When coupled, the slots and protrusions restrain movement of the ladder accessory relative to the rail. The slots allow one to quickly attach and release a corresponding protrusion of the ladder accessory, and thus allow quick attachment and release of the ladder accessory to the rail. In another embodiment, a ladder system includes a rail having an end and a body, and an attachment base mounted to the body and operable to releasably attach a ladder accessory to the rail with only one's hand.

Abstract: A quick release ladder leveler attachment system. So that a leveler may be mounted or released from the rails of a ladder quickly and without requiring the use of tools, a leveler attachment structure is added to the lower outer surface of the ladder rails. It may be integrated with the ladder rails or attached to ladder rails with bolts or rivets. The attachment structures include surfaces that engagingly mate with mounting structures on the leveler. The attachment and mating structures may be a keyhole slot and a knob. A spring catch may retain the leveler in place and a locking pin may be added to ensure safety.
