摘要： 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.

摘要： Ladder configurations and components are provided including a first assembly of rails and a second assembly of rails that are pivotable relative to each other between a collapsed configuration and an expanded configuration. A tray rotatably connected to a top cap of the ladder may include a convertible compartment, a pair of clamps, attachment points, and a ferromagnetic component. The tray may be rotatable relative to the top cap by operation of an adjustment member that locks or unlocks the tray. Rotation of the tray may position the tray in an upright position substantially parallel to the first assembly of rails and in a storage position substantially parallel to and behind the first assembly of rails.

摘要： Ladder configurations and components are provided including a first assembly of rails and a second assembly of rails that are pivotable relative to each other between a collapsed configuration and an expanded configuration. A handle coupled to a rail extends inward from the rail and has an inner end resiliently deflectable between a clearance position and a weight bearing position that engages another rail as the ladder is carried by the handle. A spreader mechanism includes a platform extending between jointed linkages and that extends the top surface of a rung coupled to two of the rails. An inner end of the platform may be used as a handle to expand or collapse the ladder. The platform may be extruded and assembled with the rung in a manner limiting pinching or gaps at an interface between the platform and the rung.
