4D Patents

Hello!

There is a thread about a Japanese 4D. I see some problems with that design.

However, the question on the subject remeains, does anyone know who holds the patents for 4D coasters operated by innner rails or other methods?

I think Arrow might have the right patents on "doable" designs to keep themselves afloat for a while.

Also, if I am wrong, I would sure like to see how other companies are approaching the 4D concept.

Which amuesment park?

Is Arrow involved?

No, park, just the Sledge Hammer prototype designed & built by the Japanese company Hoei Sangyo who also designed the world's first flying coaster (not sure where it is.) Check out this page for info on both. Drawings can be found here. They're looking for a buyer.

Note from the animation on the first page that the car doesn't invert! It uses the weight of the car (& riders) to keep it in the correct position while zooming along, no extra rails or anything. Hopefully this means it will invert in Loops & Raven Turns.

I think this is the patent for the sledghammer... Looks the same to me at least.
