The invention provides a control box for selectively delivering orders to receivers ( 8, 12 ), the control box comprising: a shaft ( 14 ) mounted to turn about an axis of rotation (X), while being capable of sliding along said axis (X) between a rest position towards which it is urged by return means ( 24 ), and an active position; order delivery means ( 16, 11 ) co-operating with the shaft ( 14 ) to deliver orders as a function of the angular position of the shaft ( 14 ); rotary drive means ( 15 ) for causing the shaft to turn; and safety actuation means ( 23 ) for causing the shaft to slide from the rest position in which anti-rotation means ( 27, 28 ) prevent the shaft from turning to the active position in which the anti-rotation means ( 27, 28 ) leave the shaft free to turn under drive from the rotary drive means ( 15 ).
1. A device for a user to operate an aircraft landing gear hatch on the ground,
the device comprising:
means ( 5 , 12 ) for operating the hatch ( 4 );
hooking means ( 6 , 7 , 10 ) enabling the hatch ( 4 ) to be locked when it reaches a closed position,
the hooking means ( 6 , 7 , 10 ) including at least one unlocking actuator ( 8 ) arranged to act on the hooking means ( 6 , 7 , 10 ) in order to deactivate them;
and a control box ( 9 ), operative by the user, for selectively delivering orders to receivers ( 8 , 12 ), the control box comprising:
a shaft ( 14 ) mounted to turn about an axis of rotation (X),
while being capable of sliding along said axis (X) between a rest position towards which it is urged by return means ( 24 ), and an active position;
order delivery means ( 16 , 11 ) co-operating with the shaft ( 14 ) to deliver orders as a function of the angular position of the shaft ( 14 );
rotary drive means ( 15 ) for causing the shaft to turn:
and safety actuation means ( 23 ) for causing the shaft to slide from the rest position in which anti-rotation means ( 27 , 28 ) prevent the shaft from turning to the active position in which the anti-rotation means ( 27 , 28 ) leave the shaft free to turn under drive from the rotary drive means ( 15 ),
wherein, in order to deliver an order, the user must act simultaneously on the safety actuation means and on the rotary drive means,
the order delivery means ( 16 ) of the control box ( 9 ) optionally being connected to the operating means ( 5 , 12 ) of the hatch and to the unlocking actuator ( 8 ) in order to run the following sequences selectively:
an opening sequence during which the unlocking actuator ( 8 ) is actuated to deactivate the hooking means ( 6 , 7 , 10 );
and a closing sequence during which the operating means ( 5 , 12 ) are actuated to reclose the hatch ( 4 ).
2. A device for a user to operate a landing gear hatch on the ground according to claim 1 , wherein the unlocking actuator ( 8 ) is an electromechanical actuator.
