  • Patent number: 5779208
    Abstract: An adjustably positionable support platform for use in combination with an extension ladder which includes a generally planar deck having a load supporting assembly to accommodate a person standing thereon. The load bearing assembly comprises a plate with a foot supporting upper surface and a ladder rung engaging lower surface. A first pair of support pins is provided for slidable engagement within brackets attached to the lower rung engaging surface, the first pair of pins being arranged to capture a ladder rung between the pin and the lower rung engaging surface. A second pair of pins is provided with a distally positioned ladder rail engaging plate to control the angular disposition of the deck so as to provide a horizontal standing surface for the user. Additionally, the plate of the load bearing assembly is provided with angularly downwardly extending flanges, with the included angle between the front flange and the plate preferably being about 75 degrees.

  • Patent number: 5316251
    Abstract: A unitary self-leveling paint can holder for providing self-leveling of a paint can in two dimensions. An elliptical frame member is provided having a major and minor axis. The frame has a cylindrical handle extending therefrom along the major axis, and a pair of diametrically opposed notches along the minor axis for receiving and pivotably supporting a paint can about the paint can handle bosses. Alternatively, a semi-elliptical frame member can be implemented. The elliptical frame design facilitates rotation of the received paint can along the major axis and about the minor axis up to 30.degree. from vertical. The apparatus is comprised entirely of aluminum and thus matches standard aluminum hollow rung ladders and is not subject to rusting. Further, the apparatus is not subject to degradation such as from paint drippings since there are no moving parts.
