Should Have Gotten A Patent, D’oh

Perhaps my check is in the mail. Brocky’s Belly Bound Bi-Bungee Bringerupper from awhile ago on the Classic.

I wonder how many patients there can be for ‘bungee in tube’..
I really like this concept but I do prefer a stiffer knee ascender and in line pull. I read where you can have both ends tend the knee ascender, but using my imagination I think the V of the two bungee legs would be a pain. Have you tried redirecting the bungee so it functions along the bilateral center line?

 

[Brocky]

Forgot to add the picture, the pulley is disconnected at the dogbone when not in use, slightly left of center when being used. The bungee stretches its full length, visible through the clear tubing.

I thought the same when I saw this, or at least a name mention in the description to give you credit.

I think I recall this. Yours while not neat and pretty with a manufactured fit to the backpad of the DMM treemotion appears to be much more functional! good redirect etc..

I doubt DMM has patented it. Your published "prior art" would invalidate any patent by anyone. If you wanted to spend the cash against a patent legal team.

Without an army of lawyers backed by cash, best way to get a useful idea out there and make a few bucks is "make them and sell them". Patents are for product/market control, costs a lot to get there. Patent law doesn't favor individual innovators.

Petzl demonstrated that patent/market reality with the Chicane.

Long live the Valiant saddle, the Adjustable Bulldog Bone (and all its offspring) and whatever Kevin Bingham dreams up next.

I used rubber grommets and o rings with accessory cord, it stays out of the way when not in use. I like their idea of bringing the bungee end to the swivel carabiner to get a double pull and centers it also. Nice improvement from mine so I called the lawyers off, plus they used red tubing.

I’m Johnny-Come-Lately here but what is the function of this Brocky? What does it connect to?

 

[Brocky]

Floating knee ascender, I’d swipe DMM’s design, minus p clips, if I made another.

Dammit, your lawyer team was so ready to go!

I'm such a spoil sport. I made this plus 5 years ago, for some reason swapped out the black Petzl foot ascender for a gold one. Otherwise the very same 5mm bungee cord "puller upper" with a minimum of design and configuration fuss. It doesn't want to wear out. Generates excellent lift, I can't climb harder/faster than it will lift the knee ascender. I clip the ring on my second bridge out of the way while ascending. When my weight is on the bridge or bridges there is no obstruction to hooking my lanyard into front D's or side D's. It stays on my harness most of the time unless I'm doing an apple/small tree prune where a knee ascender makes no sense.

. . . Patent law doesn't favor individual innovators.

Truth. I am third generation family machine works and foundry owner, with a number of patents among my immediate forebears. Total waste of time and money to have patented anything. It costs a fortune to patent something and there is no enforcement at all behind an American patent other than the patent holder's own efforts. If one is infringed by a much larger company with in-house legal team and ample budget, one is basically f*cked.

Knee ascenders??? Take a look at mine

I designed, built, and sold a novel compost tea brewer/nutrient mixer about 15 years ago, and everyone told me I should patent it. It doesn't take long to explain all the ways that that wouldn't've worth it for me in that situation. My target audience was generally people with enough brainpower to look at my machine and gerry rig a good enough version to feel like they had built "the same thing for half the price". I sold enough machines to recover the money I had spent and moved on.
