LADDER EXTENSION BRAKE
20200190904 · 2020-06-18 ·

Provided is a braking system for use with an extension ladder having a base section and a fly section movable relative to the base section via an adjustment rope. The braking system includes a bracket for attachment to the fly section. A pulley and an arm are secured to and movable relative to the bracket by the adjustment rope between a first position when no tension is applied to the rope and a second position when tension is applied to the adjustment rope. A cam is movable between an engaged position when the pulley and arm are in the first position with the cam engaging with the base section to prevent movement of the fly section relative to the base section, and a disengaged position when the pulley and arm are in the second position.

Ladder safety mechanisms
10648236 · 2020-05-12 · ·

A ladder safety mechanism comprises at least one damp, preferably a pair of spaced apart damps, attachable part way along a ladder, to secure the ladder to part of a structure. In some embodiments, the mechanism includes at least one manually operated actuator, such as a rope or cable, coupled to the at least one clamp to enable a user located at the bottom of the ladder to open the at least one clamp to receive the part of a structure. In some embodiments, the at least one clamp is automatically secured to the part of the structure by placing the clamp onto the structure. The at least one manually operated actuator also enables a user located at the bottom of the ladder to open the at least one damp to release the part of the structure. The at least one clamp is oriented substantially perpendicularly to a part of the structure to which the ladder is to be attached.

LADDERS AND LADDER BRACING
20200011133 · 2020-01-09 ·

A ladder with bracing is provided. In one embodiment, the ladder may include a first rail assembly comprising a pair of inner rails and a pair of outer rails, the pair of inner rails being slidably disposed in a upper portion of pair of outer rails, wherein a rear surface of each of the pair of outer rails lies in a common plane. A first plurality of rungs may be coupled between the pair of inner rails, and a second plurality of rungs coupled between the pair of outer rails. A brace may extend between and be coupled to the pair of outer rails, wherein the brace includes a first ramped surface, the first ramped surface having a first portion spaced away from the common plane, a second portion immediately adjacent the common plane, and a transition portion extending between the first portion and the second portion.

MOBILE ACCESS UNIT AND CAGE
20190389677 · 2019-12-26 ·

Fall restraint equipment comprising a mobile access unit having a mobile platform portion, a ladder portion, and a cage portion. The components of the fall restraint equipment are formed from butterflying, lasering, cutting, bending, and/or stamping continuous pieces of tubular and sheet metal. The components of the mobile access unit are modular and include adapters of varying height that cause the mobile access unit to exhibit varying height. Also, the mobile access unit is adaptable so that it can roll in a first direction of orientation of the ladder or a second direction perpendicular to the first direction.

Provided is a braking system for use with an extension ladder having a base section and a fly section movable relative to the base section via an adjustment rope. The braking system includes a first and a second position. When tension is applied to the rope, the spring mechanism allows upwards or downwards movement of the fly section relative to the base section. When tension is removed from the rope, the spring mechanism slows or resists upwards or downwards movement of the fly section relative to the base section regardless of the fly section's position relative to the base section.
