Abstract
An automated quick release mechanism for a three ring release includes a pneumatic or hydraulic cylinder with a hardened metal pin. The pin engages a string loop of the three ring release. An internal spring holds the pin in an extended position. A controller external to the automated quick release mechanism provides a gas or fluid pressure to withdraw the pin and disengage the string loop.
Claims9
A parachute quick release comprising:
- a cascading three ring release having a string loop closure;
- a pin having a longitudinal axis disposed substantially parallel to a longitudinal axis of said cascading three ring release;
- and
- a pin release mechanism to engage the string loop closure of the cascading three ring release, wherein the pin release mechanism includes a cylinder adapted to move the pin along a direction parallel to said longitudinal axis of said cascading three ring release, whereby in a first position the string loop closure is engage with the pin and whereby in a second position the string loop is disengaged with the pin.

A parachute quick release comprising:
- a cascading three ring release having a string loop closure;
- and
- a release mechanism including a piston disposed at least partially within a cylinder such that a longitudinal axis of said piston is disposed substantially parallel to a longitudinal axis of said cascading three ring release, whereby said release mechanism includes a first position wherein said piston is disposed through the string loop closure of the three ring release loop such that said cascading three ring release secures a harness to a parachute and a second position wherein said piston disengages from said string loop closure of the three ring release loop such that said cascading three ring release releases said harness from said parachute.
A method of releasably securing a harness to a parachute, said method comprising:
- securing said harness to a largest ring of a cascading three ring release;
- securing said parachute to at least said smallest ring of said cascading three ring release;
- disposing a string loop through said smallest ring and through an engagement aperture of a release mechanism, said release mechanism secured to said cascading three ring release;
- and
- extending a piston of said release mechanism through a first aperture of said engagement aperture, through said string loop, and into a second aperture of said engagement aperture, wherein said piston secures said string loop which in turn secures said smallest ring.
