Multi-speed winch handle gadget

OK, how about this idea. A round thing about an inch thick and the diameter of your winch with a built in handle that FOLDS over the top so the handle stays on the winch but when folded is out of the way with the grip being down. It has gearing on the inside so that the handle that is necessarily shorter than a normal handle operates with as much torque as a normal handle. Pushing it down further causes it to increase torque by 2X. So, handle in uppermost position, less torque than a normal handle, middle position, same as normal, down all the way is most torque.

I think the folded-down handle might block the winch.

I also think this would be a 3-speed-winch on top of a winch.

I have a hard imagining how this 3-speed winch would be so much smaller than the original winch, which at it's size only has one or two speeds.

And I think that with such a short lever, you would have to turn the winch uncomfortably fast. Like riding a mountain bike in first gear everywhere.

Goodonya Frog!

Draw it up and copywrite the dwg by placing a little *circle C* onnit!

Once ya figger out how the planetary gears will place/run and how much bulk it will have., yer set. Get a prototype made up and patents applied for!

I dunno *how* it would work; but I can sure see that it might!. Get 'er done right and reasonably inexpensive and the (sailing) world will beat a path to yer door.

Regards,
Paul

Already figured out the gearing. Weight is an issue if made of stainless or bronze and I figger Aluminum will wear too much, maybe ok.
Am considering gears of G10 overcoated with TiN (Titanium Nitride) for wear resistance and low weight.
It does require an "internal gear", ie, a gear with the teeth on the inside rim but that's not too bad.
