Description

RULE 1.78(F) (1) DISCLOSURE

The Applicant has not submitted a related pending or patented non-provisional application within two months of the filing date of this present application. The invention is made by a single inventor, so there are no other inventors to be disclosed. This application is not under assignment to any other person or entity at this time.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a tilt and lift jack plate and more particularly pertains to a jack plate which has both tilt and lift capabilities.

2. Description of the Prior Art

The use of devices to raise an outboard motor on a boat is known in the prior art. More specifically, devices to raise an outboard motor on a boat previously devised and utilized for the purpose of adjusting the height of a motor to meet specific requirements are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.

While the prior art devices fulfill their respective, particular objectives and requirements, the prior art does not describe tilt and lift jack plate that allows a user to adjust the jack plate with both tilt and lift capabilities.

In this respect, the tilt and lift jack plate according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose providing a jack plate which has both tilt and lift capabilities.

Therefore, it can be appreciated that there exists a continuing need for a new and improved tilt and lift jack plate which can be used for positioning an outboard motor as to both tilt and lift by use of a single jack plate, having both tilt and lift capabilities. In this regard, the present invention substantially fulfills this need.

This configuration allows the fluid to move from the reservoir, through the pump, through the control valve, to the hydraulic cylinders, and back through the control valve, and back to the reservoir.

It should be noted that there is an angle 290 of between about four degrees and fifteen degrees formed by the transom mounting brackets and slide plate holders, as shown in FIG. 6 when the bracket is in the “tucked position”. By “tucked position” is meant that the jack plate tilting cylinder ram is fully retracted into the tilting cylinder case causing the tilting action of the jack plate to be at the minimum. In other words, the tilt is at a minimum. This “tucking” angulation of the slide plate holders relative to the transom mounting brackets, and the boat transom, allows the motor to be angled “under” the boat transom. This angulation allows the motor to assist in lifting the boat hull during forward movement, and assists the boat in getting “on plane”, as is accomplished by “lift tabs”, which are commonly known in the boating industry, and to boat owners. While most transoms have some angulation, allowing the tuck of a motor, this configuration, in that instance, allows even greater motor “tuck”, which is more than the manufacturer provides in the structure of the boat hull.

As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
