| 1998 | Invention patented by Larry D. Seaman on October 26th, 1998. Abstract: A dock leveler apparatus includes a base member which is floatable on water, and the base member includes a planar base bottom surface. A ruler member is connected to the base member. The ruler member includes a planar ruler bottom edge which is perpendicular to the base bottom surface, and the ruler member includes indicia of linear length. When the base bottom surface is placed on a dock surface and when the ruler member projects perpendicularly downward from the dock surface, the indicia on the ruler member can be used for setting the dock surface at a desired level. When the dock leveler apparatus is employed, a dock level adjustment assembly can be used to make adjustments to the height or level of the dock surface. The base member is made sufficiently large so that if the dock leveler apparatus falls into the water, the entire apparatus will float in the water. The water-floatable base member can be made from a hollow shell. Also, the base member can be made from a material less dense than water such as a plastic foam. One or more magnets are attached to a side wall of the base member. A handle is attached to a top wall of the base member. The base member includes a hanger receiver. In accordance with another aspect of the invention, a pivot assembly, which includes ruler orientation locks, is interconnected between the ruler member and the base member. |
