GRCS Wannabe?

Wow, is the GRCS patented? If so...can you say "patent infringement?"

I didn't look super close, but I didn't see any drastic or meaningful differences from the GRCS!

I looked around the website a little and Kong also claims patent rights to the keylock biner design. I guess somebody needs to tell that to Petzl and Black Diamond.
 
Rocky,

YOu need to read your history books. Mark is right, Kong was the first to come up with a no snag biner. The other companies pay a royalty in order to use that design. There are other companies that came up with enough of a "varition on a theme" to avoid the royalty route.

There are a lot of too-similar features between the Kong and the Good Device.

Problem is that the GRCS is a yacht winch mounted on a plate to fix it to a tree the important part of the system does not come from arb but boats.SO really it should be the man that invented the yacht winch that should be complaining about infringements in both cases.The GRCS is not really a new invention as such just an exsisting piece of gear used in a different configuration and for an other purpose...
The other thing is that all you guys that have a problem with Kong copying the GRCS are only doing Kong a favour by complaining about it. "EVEN BAD PUBLICITY IS GOOD PUBLICITY"

AT THE END OF THE DAY IF BUCKINGHAMS CAN DO IT WHY NOT KONG???????

I actually think Kong do Greg a favour! Comparing the Kong imitation to the GRCS makes the Kong one seem really feeble. It also considerably less well made. That's really the great thing about the GRCS and absolutely to Greg's credit: it's really a no-nonsense piece of kit that does exactly what it claims to & will carry on doing so for many years.

Kong's policies and manufactuing standards are another matter altogether. For a while now I've had severe doubts and misgivings about a number of issues concerning some of their products (krabs, ascenders etc.), and their response - or rather lack thereof - to input concerning alterations or modifications.
 
Hey Todd, that should be "knock off", let's keep it clean on this site. I did see the knock off 2 years ago at the Augsburg, Germany show, in fact the Kong booth was right next to ours. I do have a US patent on the GRCS but a worldwide patent was out of the question financially. Also a patent is only as good as one's ability to pay for the lawyers needed to defend it. Thanks for all the support that GRCS users have shown. Getting to know great guys in the industry from all over the world has been by far the biggest benefit of the whole endeavor. Be Good.
 
I've been in situations where we've used 2 Winches at once. Once we had 2 Winches and a porty, the a third Winch would ahev been nice.

Has anyone used 3 or more GRCS's at one time and found it more then usefull?
 
i think that the GRCS etc. are from ships as stated.

They are a capstan drum, that you take wraps on, but just for a single layer; so no MA is lost as the drum fills forcing increasing layers as a regular winch does. The Masdam(?) rope winch doesn't loose MA either, but the track is it's grip, in the capstan strategies; 6 or so wraps would be needed + pull on free end to be able to have capstan grip line. Then the capstan can be turned as it grips the line by electricity (some electric companies have a 12 volt model mounted to trucks), gas (chainsaw etc.)or as here with a hand crank, as on ships. The ratio between the crank arm arc and the drum size yield the MA.

This simple power was all that they had for raising sails tight against the wind etc. at sea for centuries. Lives depended on it's simple but effective mechanics. In times when the crank arm was broken or lost; is where Brion Toss starts in with describing sweating in; as an effective leveraging tool, to bring men, families etc. home safely from the center of the open sea torrents.

i would think that such a patent would be run out on this olde timey machine strategy.
