RELEASE PIN AND CABLE ACTUATOR FOR 3 RING RELEASE MECHANISM

摘要

An automated quick release mechanism for a three-ring release comprising a pneumatic or hydraulic cylinder with a hardened metal pin engaging a loop of the three ring release. When engaged with the three-ring release, the pin is held in an extended position to engage the loop of the release. Actuation to withdraw the pin disengages the pin from the string loop, allowing the three-ring release to open.

主权项

1. A release mechanism for a 3-ring release system, the release mechanism comprising a solid pin release assembly (19) comprising support plate (1) having a proximal portion and a distal portion, said support plate (1) having a through-hole (2) connecting a top surface and a bottom surface of support plate (1) and comprising a perimeter, wherein said proximal portion of support plate (1) comprises a longitudinal bore (4) between a proximal end of support plate (1) and said through-hole (2), and
wherein said solid pin release assembly (19) comprises a release pin (7) in longitudinal bore (4), wherein said release pin (7) is moveable between an extended position wherein a distal end of said release pin (7) crosses proximal and distal sites on the perimeter of through-hole (2), and a retracted position, wherein said distal end of said release pin (7) does not cross said distal site on the perimeter of through-hole (2); and wherein a proximal end of release pin (7) is attached to a cable (8) in a cable assembly (18).
