Europe-based readers: While watching the company video for Ateliers Perrault, the French historical restoration firm that's working on Notre Dame, I saw this brief shot of a craftsman testing the latch for what looks to be a balcony door he's working on:
The latch rotates in two axes: First on the sagittal plane (i.e. like a bicycle wheel) on the pivot it's mounted to, then on the coronal plane (i.e. like a car's steering wheel) as the entire pipe that it's mounted to rotates.
This might be common in Europe, but I have never seen a latch like this here in the 'States; do any of you know what it's called? Here's a closer look:
Any help appreciated!

It is a typical french window latch. It is called an "espagnolette": https://en.wiktionary.org/wiki/espagnolette
Nice!
Thank you Xavier!
I agree with Jason. It's reminiscent of a Cam Bar Latch door like you'd see on travel trailers, but obviously done in a more elegant European way.
It's a cam-action door latch. Your clip shows a much prettier version of the same mechanism on the back of semi-trailers.
This looks like the same type of mechanism that exists on semi trailer doors, which the industry seems to refer to as a cam-action latch.
Xavier, Jason, Cameron, Mark, thank you all!
