The invention provides a coupling device (1), for a ladder having a bore in a headstock (4) extending between a pair of spaced apart styles, the coupling device (1) comprising: an elongate support member (6) having a mounting region (8) and a working region (7), the mounting region (8) configured to be received within the bore of the ladder to engage therewith, the working region (7) being configured to protrude from the bore and to receive and support a plurality of utility modules; and a releasable detent (9) to secure the elongate support member (6) within the bore, wherein the mounting region (8) is restrained from rotational movement relative to the bore, and the releasable detent (9) prevents longitudinal and transverse movement between the elongate support member (6) and the bore. The coupling device (1) of the invention provides a flexible ladder assembly that is adaptable to variable work environments encountered at the top of a portable ladder when used for access and conducting work.

A ladder stabilizer for step ladders and extension ladders. The ladder stabilizer is collapsible for storage. Additionally, the ladder stabilizer includes legs that are adjustable in length and pivotally secured to a rigid lateral support. The rigid lateral support also carries a step plate secured by a hinge to the lateral support. The step plate provides the point of engagement between the ladder stabilizer and a rung of the ladder.

A cargo trailer ladder assembly for safely entering or exiting a cargo trailer includes a pair of load locks that is each extendable between walls of a cargo trailer for securing cargo in the cargo trailer. A ladder is included that has a plurality of engagement points thereon. Each of the load locks is positionable in respective ones of the engagement points for storing the load locks with the ladder. The ladder is positionable to engage the cargo trailer to facilitate a user to safely climb into or out of the cargo trailer. A strap is removably coupled to the ladder and the strap can be slung over the user's shoulder for carrying the ladder.

A ladder stabilizer comprises a pair of stabilizer brackets attached to the ladder side rails at the bottom on either side. Each bracket has a C-shaped clamping mechanism that utilizes a toothed gear rack which engages/disengages with mating teeth of a corresponding gear rack on the ladder rail. The gear-like engagement of the teeth provides a positive locking of the attachment member to the ladder. A spring and locking screw allow ease of adjustment and a positive lock at the desired location along the ladder side rail. The rack is attached longitudinally along the length of each rail to provide a range of length adjustment to the feet. This permits one side to be longer than the other to accommodate a laterally sloping terrain. The brackets have rotatable, laterally extending A-frames with ground-engaging feet which self-adjust to a terrain which is sloping from front-to-back or vice versa.

A ladder stabilizer where respective ladder rails 12 and 13 pass through rail clamp sections 14 and 15 so that the feet 16 and 17 of the ladder engage the ground. The stabilizer has feet 18 and 19 which also engage the ground. These are at the end of a rail providing respective outriggers 20 and 21 so that the stabilizing forces and moments are across the bottom of the ladder. Clamps make the whole stabilizer and ladder rigid. Rails 12 and 13 are clamped in the clamp sections 14 and 15 which are in turn clamped along the outriggers, the feet are also clamped in height adjustable position. Hand operable screw clamps 22, 23, 24, 25, 26 and 27 permit adjustment so that the legs and rails and clamp sections may be positioned to best stabilize the ladder 11.

Improvements to the leg extension of an adjustable ladder leveler and, more generally, improvements to ladder legs. A shoe with a claw that folds to be parallel to the ladder leg and then slides upward with respect to the leg thereby becoming locked into position so that it cannot move away from being parallel so long as weight is applied on the ladder. If the shoe is on an extension, as the shoe slides up, it engages a safety bar that prevents release of the extension.
