What are these called?

[Sanctuary]

Does anybody know if these types of signatures have a specific name to them? :

Spoiler

I've been looking for sigs that look like those but I don't know what to search on Google or DeviantArt or anything.
Any help is appreciated.

Those are literal userbars. Go Google it.
