BACKGROUND OF INVENTION
1. Field of Invention
This invention relates to an ornamental rudder hitch cover designed to be attached to the trailer hitch of a vehicle in such a way as to be removable.
2. Prior Art
Trailer hitches are a very common and available accessory for cars and trucks. A popular trailer hitch assembly design is the receiver hitch that allows for the insertion of different accessories other than trailer hitches. The accessories are often functional such as bike carriers, steps, or platforms. Other popular accessories such as flags, symbols and propellers are ornamental with little or no function.
3. Objects and Advantages
The present invention improves on prior art by providing a distinctive yet subtle way for sailing enthusiasts to display their preferred form of propulsion and show their love of the sport. Prior art for has been limited to stickers and license plate frames that state “I'd rather be sailing”.
Motor boaters when not pulling a boat can display their enthusiasm for power boating by installing a propeller hitch cover such as U.S. Pat. No. 6,086,438 to Wang but no effort has been made to provide a way for recreational sailors to distinguish themselves.
The object of this invention is to provide a simple durable and aesthetically pleasing addition to a vehicle that will cover up an unsightly receiver hitch while providing a way for sailors to identify themselves.
These and other objects and advantages of the present invention will become apparent from the subsequent detailed description of the preferred embodiment and the appended claims taken in conjunction with the accompanying drawings.
SUMMARY
This invention relates to an ornamental rudder hitch cover designed to be attached to the trailer hitch of a vehicle in such a way as to be re-movable. In its simplest form the invention will be easily removable and have no moving parts. In some embodiments the rudder blade of the invention will be able to move up if contact is made with an object such as a curb. The preferred embodiment would provide means for the rudder blade to swing up as well as from side to side as a vehicle turns to simulate the functions of a rudder on a sailboat.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring first to FIG. 1a, there is shown a perspective view of the preferred embodiment whereby attachment of the invention is complete when the insert tube 16 is inserted into a vehicles trailer hitch receiver 10 and retained with a hitch receiver retaining pin 14 through the retaining pin hole 12 and insert tube retaining pin bore 17.
Referring to FIG. 1b, the rudder blade 30 is sandwiched between the faces of the rudder blade bracket 24 and retained by the rudder blade retaining pin 26 so as to allow rotation about the rudder blade retaining pin 26. The rudder blade bracket is attached to the insert tube 16 by means of a rudder blade bracket retaining pin 18 so as to allow a limited rotation about the axis of the rudder bracket retaining pin 18. The retaining pin may be frictionally inserted or secured by a retaining pin fastener 20.
Referring to FIG. 1c, there is shown a top view of the preferred embodiment. The rudder blade 30 is sandwiched between the faces of the rudder bracket 24. The movement of the rudder bracket 24 about the rudder blade bracket retaining pin 18 is indicated.
Referring to FIG. 2a, there is shown a perspective view of an alternate embodiment whereby the rudder blade bracket and receiver hitch insert is a rigid one piece element to be referred to as the rudder fork 22. Attachment of the invention is complete when the end of the rudder fork 22 is inserted into a vehicles trailer hitch receiver 10 and retained with a hitch receiver retaining pin 14 through the retaining pin hole 12 and rudder fork retaining bore 23
Referring to FIG. 2b, the rudder blade 30 is sandwiched between the faces of the rudder fork 22 and retained by the rudder blade retaining pin 26 so as to allow rotation about the rudder blade retaining pin 26.
Referring to FIG. 3a, there is shown a perspective view of an alternate embodiment whereby the rudder blade is a fixed part of the assembly with no moving parts. Attachment of the invention is complete when the end of the rudder assembly 28 is inserted into a vehicles trailer hitch receiver 10 and retained with a hitch receiver retaining pin 14 through the retaining pin hole 12 and rudder assembly retaining bore 29.
Referring to FIG. 3b, a side view is shown of the above mentioned alternate embodiment.
Accordingly, the reader will see that this invention will provide a simple durable and aesthetically pleasing addition to a vehicle that will cover up an unsightly receiver hitch while providing a way for sailors to identify themselves.
While the invention has been described in complete detail and pictorially shown in the accompanying drawings it is not to be limited to such details, since many changes and modifications may be made in the invention without departing from the spirit and scope thereof. Hence, it is described to cover any an all modifications and forms which may come within the language and scope of the appended claims.
