Landing gear toggle lock mechanism

A method of assembling a landing gear lock assembly for a landing gear, the method comprising:

• rotatably coupling a second end of a first lock link to a first end of a second lock link so that the first and second lock links unfold relative to each other in a first rotation direction, where the first lock link and the second lock link are distinct from a landing gear shock strut of the landing gear;
• rotatably coupling a crank link and a toggle link of a toggle lock mechanism to each other;
• rotatably coupling the toggle link to the second lock link and rotatably coupling the crank link to the first lock link so that the toggle link rotates relative to the second lock link, in a second rotation direction opposite the first rotation direction, to rotate the second lock link to a fully extended position of the second lock link relative to the first lock link;
• and
• wherein the second lock link mechanically locks in the fully extended position with rotation of the toggle link in the second rotation direction.

A method for operating a landing gear, the method comprising:

• extending an actuator to rotate a toggle lock mechanism about a toggle lock pivot axis of a first lock link, causing rotation of a second lock link that is rotatably coupled to the first lock link so that
• the second lock link unfolds relative to the first lock link in a first rotation direction, and
• a toggle link of the toggle lock mechanism rotates relative to the second lock link, in a second rotation direction opposite the first rotation direction, to rotate the second lock link to a fully extended position of the second lock link relative to the first lock link;
• and
• applying a force to a crank link of the toggle lock mechanism with at least one biasing member to further rotate the toggle lock mechanism in the second rotation direction causing rotation of the second lock link to the fully extended position and causing a mechanical locking of the second lock link in the fully extended position,
• wherein the toggle link couples the crank link to the second lock link, the actuator is coupled to both the first lock link and the crank link, and the at least one biasing member is coupled to both the first lock link and the crank link.
