SECURING DEVICE

摘要

A securing device, for example for securing an aircraft to the deck of a ship, comprises a pair of jaws (58, 60) arranged to engage a fixed member (78) on the ship. Normally, the jaws are locked open by means of a detent, but when the member (78) hits a striker plate (66), this plate moves from a detent position to an open position in which, on operation of a locking plunger (64) the jaws may be closed. The entire mechanism is connected to a ram which is arranged to retract when the jaws are locked in position, so pulling the aircraft firmly down onto the deck of the ship. The control circuit for operating the lock includes a pressure regulator arranged to lower the entire system pressure, and therefore the impact load on the deck, as the ram is being extended. In addition, when it is desired to uncouple the lock from the deck, there are means for putting the ram into compression just prior to uncoupling, so that the tensile securing loads are substantially cancelled.
