    摘要： An apparatus includes a platform having a first end and a second end and a handle. The apparatus includes a first leg assembly rotatably attached to the platform in proximity to the first end. The apparatus includes a second leg assembly attentively attached to the platform in proximity to the second end. When the first and second leg assemblies are essentially perpendicular to the platform, the apparatus is in a use state and the user is able to stand on the platform and be supported by the first and second leg assemblies. When the apparatus is in the use state, the user is able to pick up the apparatus by the handle with only one of the hands without tipping the apparatus. A method for a user with hands to stand on an apparatus.

    摘要： Ladders, ladder components and related methods are provided including various embodiments of a combination ladder. In some embodiments, a platform is provided that is fixedly coupled with a rail assembly of a combination ladder. The platform may pivot between a useable position or state and a stowed or stored position or state. The platform may maintain a position relative to certain rungs of the rail assembly while being displaceable relative to other rungs of the rail assembly. A hand rail may be coupled to the rail assembly and a tray may be coupled with the hand rail. The tray and the platform may be configured to maintain a constant distance between one another while the rail assembly is adjusted for height.

    摘要： A retro-fit installation modifies the existing pool ladder structure of an existing in-ground or above-ground swimming pool to support an underwater “swim out” platform structure. In some versions, the ladder rails of the existing pool ladder are used to support the underwater platform, while in others the existing pool ladder rails are replaced with new tubular platform rails specifically designed to support the underwater platform structure. Other versions are adapted for installations in a round pool or at a corner of a rectangular pool.
