Abstract
A lock in a vehicle is automatically controlled based at least in part on a state associated with the vehicle. In response to an attempt to open a hatch using an interior release lever while in a locked state, the automatically-controlled lock in the locked state prevents the hatch from opening. In response to an attempt to open the hatch using an exterior release lever while the automatically-controlled lock is in the locked state, a bypass to the automatically-controlled lock is used to open the hatch.
Claims21
A system, comprising:
- an interior release lever configured to open a hatch of an aircraft from an interior of the aircraft;
- an exterior release lever configured to open the hatch from an exterior of the aircraft;
- and
- a locking system having a locked state and an unlocked state, the locking system comprising:
- an automatically-controlled lock, comprising a solenoid, a pin, and a spring acting on the pin, coupled to the interior release lever, and configured to:
- in response to an attempt to open the hatch using the interior release lever, while the automatically-controlled lock is in the locked state, prevent the hatch from opening, and
- in an event of an emergency power loss while the aircraft is in air, where no power is supplied to the solenoid, such that no magnetic field is generated by the solenoid, thereby the spring causes the pin to be extended, putting the automatically-controlled lock in the locked state and keeping the hatch closed while the aircraft is in the air,
- wherein when the locking system is in the locked state, the hatch is prevented from opening using the interior release lever and is configured to be opened using the exterior release lever, and when the locking system is in the unlocked state, the hatch is configured to be opened using the interior release lever or the exterior release lever.

A system provided in an aircraft, the system comprising:
- an interior release lever configured to open a hatch of the aircraft from an interior of the aircraft;
- an exterior release lever configured to open the hatch from an exterior of the aircraft;
- a locking system including:
- an automatically-controlled lock, comprising a solenoid, a pin, and a spring acting on the pin, coupled to the interior release lever, and configured to:
- in response to an attempt to open the hatch using the interior release lever, while the automatically-controlled lock is in a locked state, prevent the hatch from opening,
- a first latch coupled to the locking system via a first torsion tube, wherein rotation of the first torsion tube releases the first latch;
- and
- a second latch coupled to the locking system via a second torsion tube, wherein rotation of the second torsion tube releases the second latch;
- wherein the exterior release lever is coupled to the first torsion tube and the second torsion tube.

A system, comprising:
- an interior release lever configured to open a hatch of an aircraft from an interior of the aircraft;
- an exterior release lever configured to open the hatch from an exterior of the aircraft;
- and
- a locking system having a locked state and an unlocked state, the locking system comprising:
- an automatically-controlled lock, comprising a solenoid, a pin, and a spring acting on the pin, coupled to the interior release lever, and configured to:
- in response to an attempt to open the hatch using the interior release lever, while the automatically-controlled lock is in the locked state, prevent the hatch from opening,
- in response to an attempt to open the hatch in the aircraft using the interior release lever while the automatically-controlled lock is in the unlocked state, permit the hatch to open and move the exterior release lever, and
- in an event of an emergency power loss while the aircraft is in air, where no power is supplied to the solenoid, such that no magnetic field is generated by the solenoid, thereby the spring causes the pin to be extended, putting the automatically-controlled lock in the locked state and keeping the hatch closed while the aircraft is in the air.

- and
- a bypass to the automatically-controlled lock coupled to the exterior release lever and configured to:
- in response to an attempt to open the hatch using the exterior release lever, while the automatically-controlled lock is in the locked state, bypass the automatically-controlled lock in order to open the hatch.
