Abstract: 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.

Abstract: 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.

Abstract: Embodiments of ladders and adjustable trays are provided herein. In accordance with one embodiment, a ladder includes a first pair of spaced apart rails having one or more rungs extending between and coupled with the first pair of spaced apart rails. A top cap is coupled with the first pair of spaced apart rails. A second pair of spaced apart rails is coupled with the first pair of rails via a pair of hinges. A tray is hingedly coupled with the top cap and selectively positioned between a first deployed position and a stored position, wherein when the tray is in the stored position the tray extends downwards from the top cap towards the pair of hinges.

Abstract: Ladders have first and second assemblies with pairs of rails that form a pair of hinges rotatable about a pivot axis. The hinges include at least one retainer movable between axial positions along the pivot axis. The at least one retainer includes a body and a support arm coupled with the body. The arm can be pivotable relative to the body between a deployed position and a collapsed position. The support arm can support objects while a user is in an elevated position on the ladder.

Abstract: A bike balance trainer apparatus for training a rider to balance on a single wheel of a bicycle and including a mount for a service stand and an attachment to allow it to act as a bike stand or storage apparatus is provided. The apparatus may have a base support member and a tire retention member movably connected to the base support member about a first pivot.

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: A chain separator for separating a chain of a bicycle from a sprocket of the bicycle. The chain separator includes a body defining an outer surface and at least one projection extending from the body to define a sprocket channel. The chain is disengaged from the sprocket and positioned on the outer surface and the chain separator is positioned on the bicycle such that the sprocket is positioned within the sprocket channel.

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.
