Abstract
A parachute ring release mechanism with a spring incorporated to insure disengagement of the parachute risers. The ring release is structured such that the parachute risers may be released by either one of two rip cords.
Claims20
A spring ring release mechanism that detachably connects the risers of a parachute to a parachute securing member comprising:
- (a) a first ring attached to said riser;
- (b) a series of loops each directly attached by means to said parachute securing member, having a first loop passing through the inner circumference of said first ring connecting said first loop to said first ring, each additional loop passing through the inner circumference of each preceding loop, connecting each additional loop with each preceding loop;
- (c) a flap attached to said parachute securing member, said flap having a first aperture near one end;
- (d) a flexible thong attached to said parachute securing member, said flexible thong passes through the inner circumference of the last loop in said series of loops and through said first aperture;
- (e) a first rip cord detachably connected to said flexible thong, whereby said flexible thong is prevented from passing through said first aperture;
- (f) a tension spring attached to said parachute securing member and said flap, whereby said tension spring pulls said flap away from said series of loops after said first rip cord is detached from said flexible thong.

A spring ring release mechanism that detachably connects the risers of a parachute to a parachute securing member comprising:
- (a) a first ring attached to said parachute riser;
- (b) a series of loops directly attached to said parachute securing member by a series of attached webs, said webs having a second aperture, said series of loops having a first loop passing through the inner circumference of said first ring connecting said first loop to said first ring, each additional loop passing through the inner circumference of each preceding loop, connecting each additional loop with each preceding loop;
- (c) a flap attached to said parachute securing member;
- (d) a flexible thong attached to said flap, said flexible thong passes through the inner circumference of the last loop in said series of loops and through said second aperture;
- (e) a second rip cord detachably connected to said flexible thong, whereby said flexible thong is prevented from passing through said second aperture;
- (f) a tension spring attached to said parachute securing member and said flap, whereby said tension spring pulls said flap away from said series of loops after said second rip cord is detached from said flexible thong.
