Abstract: A support kit supports a free-standing ladder. The kit includes a support frame with adjustable legs to keep the support frame level and a ladder-receiving bracket pivotally mounted on the frame about an axis extending laterally of the frame. A set of struts is pivoted to the frame spaced from the ladder-receiving bracket and extend to connect to the ladder-receiving bracket to form a structural triangle. Another set of struts is pivoted about a lateral axis spaced from the first set of struts and extends to a strut-receiving bracket mounted to the ladder above the ladder-receiving bracket to form a second structural triangle.

Abstract: Ladder stabilizers for lateral attachment to an extension ladder for inhibiting sideways slipping and falling thereof accordingly to full safety. A long tube support made from non-rusting, a non-articulated bracing member, and a ladder side rail form an A-frame with the tube support and the side rail comprising the legs of the A and the bracing member comprising the horizontal connecting member of the A. The lock for the telescoping sections visibly indicates they are locked, this as per American National Standard ANSI A14.2-1990, par. 6.7.10, the installation being fully secured because of the technically safe locking device the telescopic tube is blocked with a spring pin. Ladder stabilizers are telescopic tubes for uneven ground and are pivotable along only the same surface of the ladder, thus enlarging the sustentation polygon for ladder support. For storage position, horizontal braces are detached and rotate about a metal attachment on the side rail of the ladder to become parallel with the ladder, the telescopic tubes are also in the same position and are firmly tied with a tension hook. This ladder stabilizer is to be added to any existing ladder extensible or non-extensible.

Abstract: Stabilizer apparatus for attachment to an extension ladder for inhibiting sideways tipping and downward/rearward slipping thereof. Attached to the opposed side rails of the ladder proximate the upper end of the lowermost section are hinge blocks for pivotally joining a pair of tubular, telescoping, extensible legs to the ladder. The hinge brackets are specially designed to permit the tubular legs to be swung parallel to and directly adjacent with the ladder's side rails when the ladder is to be stowed and which the legs to be rotated laterally outward and forward of the base of the ladder during use. An articulated brace extends between the pair of legs and their associated ladder side rails to limit the extent to which the legs may be splayed relative to the ladder.

Abstract: A pair of elongated stabilizing supports and a pair of mounts for support by opposite side rails of the ladder. The stabilizing supports each include a pair of generally parallel arms and have a first pair of end portions free of connections extending therebetween and connecting structure extending between and connecting the second pair of end portions thereof. Support structure mounts the stabilizing supports from the mounts in upwardly convergent positions with the first pair of end portions uppermost and for lengthwise adjustable shifting of the stabilizing supports relative to the mounts. The first pair of end portions of the stabilizing supports, when the latter are in upper adjusted positions thereof, embracingly receive the corresponding ladder side rails therebetween. The support structure includes support portions from and relative to which the stabilizing supports are lengthwise adjustably shiftable and the support portions are mounted on the mounts for angular displacement about generally parallel axes at least substantially normal to a plane containing the side rails of the ladder.
