I'm not a patent lawyer, but I have dealt with patents. The important part is the claims, because that lists what it is they are actually patenting. But since their only claim is about the design the only real relevant information is those pictures and the short descriptions of them.
Note that I'm not attempting to argue over where that should be a valid patent or not, just why it is so bare. If there were more specifics, you'd see them on that page.
Yes, that's my point. There's not much specifics because there's not much other details that need to be provided to explain the claims. IE. The claim basically just says "look at the pictures".
