Abstract: An apparatus that fits onto a ladder for securing the ladder safely to a circular pole. The apparatus has a pair of curved arms that are each rotatable about a pivot so that they will close onto a pole. The arms are caused to rotate by a lever portion that contacts the pole as the ladder is forced toward the pole such as when it is set up and when a climber begins to climb the ladder. As the lever portion is forced against the pole the curved arm rotates to enclose the pole. The arms have a symmetrical control element in the form of meshed gears so that they act symmetrically as they are set up initially and as they rotated into the enclosing position.

Abstract: Described is a ladder safety device for use with non supported ladders and methods of using such a device. The device has a cross bar and hooks extending from it. The hooks will engage the rails or a rung of the ladder and hold the cross bar tightly against the ladder rails. Legs extend in the opposite direction with feet that will sit on the structure which is commonly a roof, but could also be any structure in which a ladder extends beyond a support line.

Abstract: A ladder stabilizing apparatus for holding a ladder in a fixed position against a building structure. The ladder stabilizing apparatus includes a frame having arms adapted to engage and rest upon an upwardly presented surface of a building structure. The position of the arms relative to the ladder held by the stabilizing apparatus is adjustable, such that they can extend outwardly or be retracted inwardly with respect to the position of the ladder. Further, the angle of the frame relative to the ladder can be adjusted so as to engage the eave or the rake of a roof which is other than a flat roof. A substantial downward force, which may have a horizontal force vector no greater then the downward force, is applied to the building, and particularly the roof of the building using a lateral force is applied to the ladder while using the stabilizing apparatus of the invention.
