Michael Jackson spacewalk patent number

MJ didn't apply for a patent for spacewalk, but he applied for a patent for 45-degree tilt in SmoothCriminal, and the U.S. patent number is (U.S. patent number US5255452). When MJ filed a patent application for this behavior on June 29, 1992, it was passed on June 26, 1993 with the patent name. Technical details: Grab the heel of the shoe with a grappling hook to achieve the visual effect of leaning forward 45 degrees. At the same time, the "grappling hook" system of the stage can be accurately extended and retracted without being discovered through the control of precision instruments. But the key to success lies in Michael and the actor's hard exercise, running-in, and strong back muscle and body balance control! When doing this action, one leg bears 146 kg, which few people can imitate so far.
