Patents for pano head or tilt head?

[nick fan]

Dear Members,

I have some great pano head design that may be patent worthy.
if you have seen any patent related to pano head, tilt head, angle divider etc, please let me know.
as a reward for relevant contribution, you get $100 discount for buying any Fanotec products. Further, one of the contributors will win (by lucky draw) an NN Ult M2 when released this year.
