摘要： The safety ladder may be an extension ladder having two or more relatively sliding sections, and incorporates a number of safety devices. The lower end of the ladder incorporates two opposed lateral stabilizers and two outwardly extending stabilizers, i.e., extending from the opposite face of the ladder from the structure against which the ladder is placed. The upper end of the ladder includes a pair of articulating lateral arms that brace against the structure against which the ladder is deployed, and articulating clamps or straps for securing the ladder to the structure. The medial portion of the ladder includes a handrail extending from each ladder rail. All of these devices may be retracted, collapsed, and/or folded for compact storage and transport when not in use. The entire ladder, i.e., rails, rungs, as well as the various safety components attached thereto, is coated with an electrically non-conductive coating for additional safety.

摘要： An improved device for stabilizing and stiffening an extension ladder includes a telescoping member with proximal and distal ends, a base that is attached to the proximal end of the telescoping member and has a configuration which is adapted to allow it to be adjustably affixed between the rungs of the ladder so that the angle between the centerline of the telescoping member and the plane defined by the extension ladder's rungs can be adjustably set so that the distal end of the telescoping member extends approximately horizontal to contact the vertical surface against which the extension ladder is leaning, and a transverse member that is attached to the telescoping member's distal end and has a configuration which is adapted to enhance the ability of the ladder to resist twisting about the centerline of the ladder.

摘要： A ladder stabilizer to be utilized in conjunction with and to stabilize an A-frame ladder. The ladder stabilizer of the present invention comprises an I-shaped attachment plate which has screw holes for attachment to the ladder. Extending angularly downward from the attachment plate is a first leg member. A second leg member fits inside the first leg member and is sized and shaped appropriately so that it may telescope in and out with respect to the first leg member for leg length adjustment. At the bottom of the leg, the second leg member is angled downward so that the bottom of the leg will rest securely on the ground or floor.

摘要： A knee brace for a ladder including a first flange and a second flange. The brace includes a web extending from the first flange and the second flange which together form a u-shaped cross-section. The brace includes a first portion that connects to a step. The brace includes a second portion which connects to the rail and terminates at a distance from a joint. The second portion's first and second flanges and web presenting three contact surfaces which connect to the rail and extend essentially in parallel with the rail and conforms with the rail to which the knee brace is attached so forces can be transferred therebetween. The first and second flanges contact a first rail flange and second rail flange, respectively, and the web contacts the web of the rail of u-shaped cross-section. The brace includes a first rivet extending through the first rail flange and first flange. The brace includes a second rivet extending through the second rail flange and the second flange adjacent the rail end. A method for using a ladder.

摘要： The invention is directed to strong, lightweight, electrically non-conducting ladder stiles and ladders formed therefrom. Each ladder stile comprises a tension and compression portion structurally interconnected by a spacing portion. The spacing portion has a cross section which varies over the length of the stile between sections where the entire spacing portion is the full width of the stile and sections where at least part of the spacing portion is less than the full width of the stile. The ladders of the invention are formed of two ladder stiles interconnected by rungs.
