Based on the description of friend I drew this small example of a specific pan-tilt mechanism I'd like more information on, but as I'm not an engineer I don't really know what terms to use and can't seem to find anything. I think I might have seen it somewhere related to nautical devices once, but I'm not sure.
The system I'm looking for uses two cylinders with a slanted face. Both are able to rotate around their central axis. As part B (top part) is connected to part A (bottom part) at the center of their slanted faces, it moves together with part A but is also able to rotate around it's own axis, combining both their movement and creating a lot of freedom in achievable positions. See the image below for a 3d impression of the shapes and a 2 schematic of how they rotate (where the dotted line would be their rotational axis).
Any idea what this is called, or what to look for?
