Abstract
A system for securing under an aircraft a jettisonable load having either a known suspension ring or a known suspension bridge with laterally spaced recesses. The carrier structure on the aircraft includes a withdrawable pivot pin for supporting a hook which can be removed and turned through 180.degree. for presenting optionally a single projection to engage with a suspension ring, or a pair of abutments to engage in the recesses of a suspension bridge. The hook is releasably angularly coupled to an actuating shank pivotable about the pin.
Claims3
In a system for securing, under an aircraft, a jettisonable load having selectively a suspension ring and a suspension bridge with laterally spaced recesses, in combination:
- i. a carrier structure, for mounting on the aircraft, including a horizontal transverse pivot pin releasably engaged therein,
- ii. a shank having a first end and a second end, said first end being freely rotatably journalled on said carrier structure, said second end being adapted for connection to means for moving the shank angularly into a holding position and into a releasing position,
- iii. a hook member having a first end and a second end, said first end being freely rotatably journalled on said pivot pin, said second end having thereon a single element projecting in a radial plane from one side of the hook member and adapted for engagement in a suspension ring, said second end having thereon a pair of axially spaced abutments projecting in a radial plane from the opposite side of the hook member and adapted for engagement in the laterally spaced recesses of a suspension bridge,
- said shank and said hook member having portions abutting such that said shank and said hook member are coupled for angular movement about the axis of the pivot pin.
