Abstract
This device with independent hooks and automatic locking mechanism for hooking loads suspended under aircraft comprises an effort scaling-down device associated with each hook, mechanisms for coupling the two scaling-down mechanisms with each other, and the detent-positioning of this coupling mechanism through the medium of a third common scaling-down device. Thus, the preliminary manual cocking, i.e. the detent-positioning of the coupling, provides at the same time the simultaneous resetting of the first pair of effort scaling-down mechanisms associated therewith, so that the suspension hooks are free with respect to the retaining mechanism and can pivot to their closed position independently of each other under the action of the load suspension rings when the load is fixed in position, the third scaling-down device further assisting in reducing the efforts exerted on the common retaining pawl, the raising of this common pawl being necessarily attended by the simultaneous opening of the hook.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
