Tow Vehicle Accessory, A Must.....!
 

Wondering if anyone out there would be interested in dressing up your tow rig. A majority of us have Twin Screws hangin off the back of our "pride n' joy", so why not show it off out of the water. Let me know how many guys/gals out there want one or two for the up coming boating season!!! Im in the process of patenting the system, so bring me some orders. ( fits regular 2" hitch receivers - take the ball out and slide the Twiin Screw hitch right in.....)

What....no counter-rotation??? :)

What kind of cost are you considering? I'll volunteer to be your first and can offer free advertising!:D

The cost is going to be $75 + shipping, or if your local to Kansas City we could possibly meet to complete the deal. Thanks for the interest Holy Smokes, where abouts are you in OP ?

i have a buddy that built on for trips, and put lights in the middle for when he breaks, its pretty cool

Good luck with your venture, patents are very expensive, hope it all works out

Patients are $$, typically they run about 8k-10k depending on the patient attorney and complexity of the documentation. They are not really that useful all the time, they simply give you more legal firepower to go after copy cats....in this country. There are local inventor groups in about every major city and they are really good resource for info.
That being said, IMHO , what you have there is a good idea and I think you will be about to sell some of them, but not really an innovative concept or design, thus requiring a patient. I doubt you can sell enough of them at sufficient profit to recoup the costs associated with a patient . Besides all you have them is US patient and some shomo in China is just gonna make them for 3 dollars anyhow.

I am mechanical design engineer and have several customers who are inventor types and one in particular has had had several things hit really well and sold the right to Betty Crocker etc. He claims these things are niche and the market shelf life is about one year. In a year everyone that is interested in product XYZ will hear about and purchase products like this . The rest of the world does not care about it and after about a year the majority of your consumer base is flooded and your sales #s go way way down. His theory is hit the market 1st, get as much of the initial surge as possible and let the copy cats roll in for the scraps.

If your heart is set on doing a patient I can help you out with the mechanical drawings for the documentation.

Correct. I hold a couple of patents (for data networking) & you simply cannot just "add on" to an existing idea. For example, it you did have a patent on the twins, someone couldnt just add one more & say for triples. I think your idea is cool, but it looks like you just added on to the single hitch props.

Now if you maybe could use a power source such as from the trailer circuit to power small motors to spin the props, that i could see getting a patent. But then like Happy Hours said, it costs so much to get a patent that you probably would never break even.

Good luck

That studio picture just doesn't do 'em justice !!! :D

Patented or not, they look great.
