And this is the mechanism. Can you guess how it works?
Hint: the iron disc carrying the locks can rotate, and the handle on the right can be lifted up.
@patrick Correct! 🎉
Ciao Bernie, very long time no see, maybe you don't even remember who Patrizio is... 😀
However, I understand the mechanism of gate, but I'm curious.. and cannot arcive how the hypothetical 3 remaining authorized owners can "disable" the fourth owner'lock who is no longer authorized (without him returning key lock). I mean a clean way, not cutting lock with large wire cutters!
@Izio I knew a few people called Patrizio, but your profile doesn't give away a lot in terms of hints.
Have we been coworkers? Have we been together in the "servizio di leva"?
Anyway, welcome to Mastodon!
It's certainly a very interesting approach, thanks for sharing!
