Abstract: A safety ladder (100) for mounting between a support surface (1) and a ground surface (2) includes two support assemblies (20,20') and parallel step members (30) pivoted between the support assemblies (20,20'). Each support assembly (20,20') includes first and second support rods (21,22) each having upper and lower ends. The upper ends (211,221) of the first support rods (21) of the support assemblies (20,20') are configured to be pivoted to the support surface (1). The safety ladder (100) is movable between a use position, in which the lower ends (212,222) of the first and second support rods (21,22) of the support assemblies (20,20') are adapted to simultaneously contact the ground surface (2), and a storage position, in which the first and second support rods (21,22) stand substantially perpendicular relative to the ground surfaces (2).

Abstract: A ladder and ladder accessory are provided including an accessory that may be coupled to the ladder in multiple configurations and serve multiple purposes. In one embodiment, a pair of components are each selectively coupled with associated rails of a ladder in a first, stored state, and a second, walkthrough state. When in the walkthrough state, the components extend upwards from and above the rails so that a user may gasp the components and step between the components when transitioning from the ladder to an elevated surface (e.g., a roof) or vice versa. In another embodiment, the components may be coupled to the ladder such that they extend in a direction that is substantially transverse to a plane through which the rails extend. When in this transverse orientation, the components may be used as a stand-off device.

Abstract: A system and method for a coupling housing. The housing houses a coupling, such as a cable. The housing is coupled to a lift via an attaching device. The coupling can be lowered down to secure to ground equipment. This allows a stranded lift, such as a ski lift, to be properly secured to the ground equipment. This allows for the safe and efficient removal of any stranded passengers.

Abstract: The current invention is directed to a clamping assembly for clamping a ladder to a support such a roof gutter wall or scaffolding tubing. The clamping assembly includes a pair of opposing arms hinged together and spring biased to assist in locating the clamping arms about the support. The inner side of the clamping arm has a recess to accommodate the support or part thereof. The clamping assembly has a fastener to fix the clamping arms in position and a securing means such as a fixed chain to position about the stile or rung of a ladder. The clamping assembly provides the advantage that a section of the clamping arms clamps to a section of the support thereby providing a clamping force over a sectional area rather than at a single point.

Abstract: 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.

Abstract: Embodiments of the Lighted Ladder are comprised of a ladder; a plastic housing; one or more LED strip lighting; a cordless battery mounting means; a battery; a controller housing; a control interface; power wiring; potentiometer wiring; and motion sensor wiring. The ladder is weight-balanced by placement of the battery mounting means, the battery, and controller housing in a low position on the ladder. The battery mounting means is designed to accept a cordless tool battery. The battery mounting means is designed to accept a commercially available battery of at least 12V and at least 3.0 Ah. One plastic housing is located on each of the vertical front rails. Each LED strip lighting can illuminate an angular range of 120 degrees (120) creating a total illumination range of 300 degrees (300).

Abstract: A ladder stabiliser (10) is shown stabilising a ladder (11) 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 stabiliser 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 stabilising forces and moments are across the bottom of the ladder. Clamps make the whole stabiliser 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 stabilise the ladder (11). Each foot assembly (28, 29) includes an outer guideway in the form of a collar (30) welded and (31) welded to the outriggers and slidable leg sections (32, 33). The leg sections have a respective pivoting foot (18,19) and a cap (34, 35) so that the foot (18, 19) and caps (34,35) prevent the post part (32, 33) from being removed from the guide collar. Each of the rail clamp sections are housing slidable along the outriggers by reason of collars (36, 37). All parts are non-removable.
