Invented in its original large ring form by Bill Booth, and subsequently scaled down for thinner Type 17 webbing risers the three-ring system allows a skydiver to quickly cut-away a malfunctioning main parachute with a single motion. Skydivers usually need to do this quickly during emergencies in which they need to deploy a reserve parachute. The three-ring system is simple, inexpensive, reliable, and requires fewer operations than earlier parachute release systems while reducing the physical force needed. The large bottom ring is securely attached to the skydiver's harness, the middle ring is securely attached to the end of the parachute riser, and the small ring is securely attached to the parachute riser above the middle ring. The middle ring is passed thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

At the time, its segments were known as Beihuan (North Ring), Donghuan (East Ring), and Nanhuan (South Ring), respectively.
