Abstract: Platform systems can support a user at an elevated position while being drivable or mobile via wheels and a drive system. Rail assemblies can be folded or collapsed so that the platform system can be carried by a user from one location to another. Hand controls are operable by the user from the elevated position to move the platform systems across a ground surface and can have automatic braking capability. Each side of the platform system can be independently driven, thereby allowing zero point turning and other fine control maneuvers. Structures at the base of the platform system can limit or prevent tipping or tilting. A cage system can help keep a user on the platform(s). Platforms can be collapsed or stowed with the rest of the platform system.

Abstract: Various embodiments of ladders, ladder legs, ladder feet, foot mechanisms for ladders, and related methods are provided herein. In one embodiment, a foot is pivotal relative to a leg or rail of the ladder between a first position and at least a second position. A biasing force is applied to the foot to maintain the foot in either of the user-selected positions until a force is applied to pivot the foot to another position. In one embodiment, the foot mechanism maintaining the foot at a desired position may include a pair of pins that couple the foot to another component (e.g., a housing member, an insert member or a rail of the ladder). At least one of the two pins may be displaceable relative to the other pin during pivoting of the foot.

Abstract: Ladders and ladder components are described herein, including multipurpose and adjustable ladders. In one embodiment, a ladder includes a first assembly having rails and rungs, a second assembly having rails and rungs, and one or more hinges coupling the first and second assemblies together such that the first and second assembly may be positioned relative to one another in at least a position or state and at least a second position or state. A top cap is coupled to the rails of the first assembly, such that when the first and second assemblies are in the first position, the rails of the second assembly do not contact the top cap. When the first and second assemblies are in the second position, each rail of the second assembly is at least partially nested in one of a pair of channels formed in the top cap.

Abstract: Ladders and ladder components are provided including feet for ladders configured for securement of the ladder to a supporting surface, adjustable leg members for ladders, bearing members for ladders, and adjustment mechanisms for ladders. In one embodiment, an adjustment mechanism may include a first pair of spaced apart rails, a pair of adjustable legs having a first end hingedly coupled to one of a pair of adjustment mechanisms and a second end coupled with a foot. The adjustment mechanisms may be slidably coupled with the rails and in one embodiment, each adjustment mechanism is selectively displaceable along a length of its associated rail only when upward force is absent from the adjustment mechanism, the upward force being defined in a direction from a lower end of the associated rail towards the adjustment mechanism.

Abstract: Ladders and ladder accessories for articulating ladders are mountable to an upper rung of the ladder and can remain attached to the upper rung while the ladder articulates between collapsed, straight, and step ladder configurations without binding or engaging other rungs. The accessories can be top caps configured to hold tools and parts while the user climbs and stands on the ladder. The accessories can be removed from the ladder without damage to the accessory or the ladder, thereby enabling retrofitting ladders with the accessory or moving the accessory to different rungs or positions on the same ladder. Some accessories can have more than one body portion, and a portion can therefore pivot relative to another portion to enlarge the working platform offered by the accessory and to provide additional surfaces for temporarily supporting the accessory parts on the ladder rungs.
