pin in a pin

by **samfishers** » 31 Aug 2007 16:00

ok so there is the question:

does it exists.

i was thinking about that, what if you could have a something like 2 different shear lines, but in line (one on top of the other). so you would need a driver and a bottom pin with a hole in it and a bottom and a driver pin smaller so they could fit in the hole of the first pin.

you get it?

There's a pretty good set of diagrams in the Mul-T-Lock patent: search for patent #5,123,268 in Google Patent Search.

Hey... don't feel too badly: the pin-in-pin is a very neat design. Sadly, you won't be getting any royalties... but, personally, I'd feel pretty good to have thought it up, and then discovered that it actually works well enough in practice that somebody's using it. :-)

Matt Blaze has an excellent set of photos on his site: LINK. His discussion at the bottom of the article, about the improvements that Mul-T-Lock has made, is quite interesting as well.

There's actually two different types of pin inside a pin. MulTLock is one, the other is called a Wise lock and has open-sleeved pins. The outer pin in a MulTLock has a closed end. The Wiselock is old and isn't very secure because they only used one set of concentric pins (with 3 or 4 sleeves).

The Drumm Gemini, or however it's spelt, has 'em.

If you seach Google you're sure to come across the TOOOL white paper regarding them.
