ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention is directed to a boat ramp assembly for marine applications. In one embodiment, the boat ramp assembly includes a floating dock assembly. In many prior boat ramps, the ramp was constructed of concrete. In these prior art boat ramps, this required that a cofferdam be built to hold back the water while excavating the earth at the ramp location. The cofferdam was also normally required to hold back the water while pouring the concrete and during the initial curing of the concrete. It was not unusual for the cost of a prior art cofferdam concrete ramp construction to be in the neighborhood of $500,000.
It was also known in the prior art to construct a dock adjacent the concrete boat ramp. Normally such a dock extends perpendicular to the shoreline adjacent the boat ramp.
SUMMARY OF THE INVENTION
The present invention is directed to a boat ramp assembly for use at, for example, a marina. The boat ramp assembly includes a rectangular frame having opposed first and second ends and a top and bottom. An metal support surface, which normally comprises a plurality of metal sections, is mounted adjacent the top of the rectangular frame.
The metal support forms the upper bearing surface of the boat ramp.
A shore support is positioned adjacent the first end of the rectangular frame. The shore support includes a peripheral frame which is held in place by stone, rocks or concrete. A mounting connector is positioned between the first end of the rectangular frame and the shore support.
In one embodiment, the boat ramp assembly includes a floating dock assembly which is positioned adjacent the rectangular frame. The floating dock assembly includes a main floating dock portion, an intermediate parallel arm section and a shore mount assembly. The main floating deck assembly includes a plurality of support floats and a rectangular dock mounted on the floats. The intermediate parallel arm section includes parallel arms pivotally mounted between the main floating dock assembly and the shore mount assembly. At least one cylinder is operatively connected between the shore mount assembly and the intermediate parallel arm section.
