An actuating system for an actuatable door and to an actuatable door having such an actuating system are provided. The actuating system comprises first and second rotatable latching shafts, a coupling link, first and second pivotable mechanical transmission elements that are mounted onto first and second rotatable latching shafts, respectively, and first and second latching members. First and second latching members are non-rotatably mounted to the second rotatable latching shaft and adapted for latching the actuatable door in a closed position. A first rotation of the first rotatable latching shaft results in pivoting of the first and second mechanical transmission elements and a second rotation of the second rotatable latching shaft, which causes a third rotation of first and second latching members.

Actuating system for an actuatable door

An actuating system for an actuatable door and to an actuatable door having such an actuating system. The actuating system comprises first and second rotatable latching shafts, a coupling link, first and second pivotable mechanical transmission elements that are mounted onto first and second rotatable latching shafts, respectively, and first and second latching members. First and second latching members are non-rotatably mounted to the second rotatable latching shaft and adapted for latching the actuatable door in a closed position. A first rotation of the first rotatable latching shaft results in pivoting of the first and second mechanical transmission elements and a second rotation of the second rotatable latching shaft, which causes a third rotation of first and second latching members.

An actuating system for an actuatable door and to an actuatable door having such an actuating system. The actuating system comprises a rotatable latching shaft, a rotatable locking shaft, a latching device, comprising a latch, and a locking device. The latch is adapted to maintain the actuatable door in a closed position. The locking device comprises a locking cam, that is mounted to the locking shaft and that is adapted to engage with the latch in a closed and latched position, and a latch securing lever, that is driven by the locking cam and that is adapted to engage with the latch to maintain the latch in a closed and secured position.

An emergency opening system () of an aircraft cabin door () mounted in an aircraft fuselage structure () by means of a hinge arm (). An actuator (), designed to assist the opening of the aircraft cabin door () against the force of gravity by means of a gas operated actuating rod () is mounted with its fix end () to said hinge arm () and said actuating rod () is connected to an actuator joint (). A fork lever () is linked to said actuator joint (). A bell crank () is respectively pivotable mounted to said hinge arm () and to said actuator joint () for the fork lever (). At least one coupling lever () is pivotable joint to said fork lever () at at least one coupling joint (). Said at least one coupling lever () is mounted in at least one hinge () of the hinge arm () by means of a respective bolt (), said bolt () being drivingly connected to said aircraft cabin door () for rotation of said aircraft cabin door ().
