ABSTRACT:
A coupling device which is mechanically two fault tolerant for release. The device comprises a fastener plate 11 and fastener body 12, each of which is attachable to a different one of a pair of structures to be joined. The fastener plate 11 and body 12 are coupled by an elongate toggle 13 mounted at one end in a socket on the fastener plate for universal pivotal movement thereon. The other end of the toggle 13 is received in an opening in the fastener body 12 and adapted for limited pivotal movement therein. The toggle is adapted to be restrained by three latch hooks 55 arranged in symmetrical equiangular spacing about the axis of the toggle, each hook being mounted on the fastener body 12 for pivotal movement between an unlatching non-contact position with respect to the toggle and a latching position in engagement with a latching surface 44 of the toggle. The device includes releasable lock means 61, 63 for locking each latch hook 55 in its latching position whereby the toggle couples the fastener plate to the fastener body and means 70, 72 for releasing the lock means to unlock each said latch hook from the latch position whereby the unlocking of at least one of the latch hooks from its latching position results in the decoupling of the fastener plate from the fastener body.
