1. A track lock assembly for a thrust reverser comprising: a translating sleeve;a track beam adjacent the translating sleeve, the translating sleeve mounted on the track beam for translating movement relative thereto;a lock assembly mounted to one of the translating sleeve or the track beam, wherein the lock assembly comprises a pivoting lock arm, the pivoting lock arm pivoting in a plane that is generally normal to the axis of translation of the translating sleeve;a ramp mounted to the other of the translating sleeve or the track beam;wherein the lock assembly is configured to secure the translating sleeve against translation relative to the track beam when the pivoting lock arm is in a locked position, wherein the pivoting lock arm is configured to engage the ramp; andwherein when the translating sleeve is deployed and moves toward its stowed position, the pivoting lock arm is pivoted by the ramp until the lock arm clears the ramp. 2. The track lock assembly of claim 1, wherein the lock assembly further comprises a shaft, a housing, and a spring, wherein the shaft is coupled to the housing, wherein the pivoting lock arm is configured to rotate with the shaft, and wherein the spring is coupled to the housing and the pivoting lock arm and configured to bias the pivoting lock arm to rotate with the shaft in a first direction. 3. The track lock assembly of claim 2, wherein in response to the translating sleeve translating from a deployed position to a stowed position, the pivoting lock arm is configured to interact with the ramp, the interaction causing the pivoting lock arm to rotate with the shaft in a direction opposite the first direction, wherein in response to the pivoting lock arm having cleared the ramp, the spring is configured to rotate the pivoting lock arm to a closed position. 4. The track lock assembly of claim 3, wherein the plane of rotation is normal to the direction of the translation. 5. The track lock assembly of claim 2, wherein the lock assembly further comprises an electric motor, wherein the electric motor is coupled to the shaft, wherein the electric motor is configured to rotate the pivoting lock arm from a closed position to an open position. 6. The track lock assembly of claim 2, wherein the lock assembly further comprises at least one of a hydraulic or pneumatic system, wherein the at least one of a hydraulic or pneumatic system comprises an actuator housing and a piston, wherein the piston is located at least partially within the actuator housing. 7. The track lock assembly of claim 6, wherein the piston is configured to protract from a cylinder, wherein in response to the protraction, the piston is configured to rotate the pivoting lock arm from a closed position to an open position. 8. The track lock assembly of claim 2, wherein the housing comprises aluminum. 9. The track lock assembly of claim 2, wherein at least one of the pivoting lock arm and the ramp comprises at least one of steel or aluminum. 10. A nacelle comprising: a translating sleeve;a track beam adjacent the translating sleeve, the translating sleeve mounted on the track beam for translating movement relative thereto;a lock assembly mounted to one of the translating sleeve or the track beam, wherein the lock assembly comprises a pivoting lock arm, the pivoting lock arm pivoting in a plane that is generally normal to the axis of translation of the translating sleeve;a ramp mounted to the other of the translating sleeve or the track beam;wherein the lock assembly is configured to secure the translating sleeve against translation relative to the track beam when the pivoting lock arm is in a locked position, wherein the pivoting lock arm is configured to engage the ramp; andwherein when the translating sleeve is deployed and moves toward its stowed position, the pivoting lock arm is pivoted by the ramp until the lock arm clears the ramp. 11. The nacelle of claim 10, wherein the lock assembly further comprises a shaft, a housing, and a spring, wherein the shaft is coupled to the housing, wherein the pivoting lock arm is configured to rotate with the shaft and wherein the spring is coupled to the housing and the pivoting lock arm and configured to bias the pivoting lock arm to rotate with the shaft in a first direction. 12. The nacelle of claim 11, wherein in response to the translating sleeve translating from a deployed position to a stowed position, the pivoting lock arm is configured to interact with the ramp, the interaction causing the pivoting lock arm to rotate with the shaft, wherein the spring is configured to oppose the rotation, wherein in response to the pivoting lock arm having cleared the ramp, the spring is configured to rotate the pivoting lock arm to a closed position. 13. The nacelle of claim 12, wherein the plane of rotation is normal to the direction of the translation. 14. The nacelle of claim 11, wherein the pivoting lock assembly further comprises an electric motor, wherein the electric motor is coupled to a pivot, wherein the electric motor is configured to rotate the pivoting lock arm from a closed position to an open position. 15. The nacelle of claim 11, wherein the pivoting lock assembly further comprises one of a hydraulic, pneumatic, or electric system, wherein the one of a hydraulic, pneumatic, or electric system comprises an actuator housing and a piston, wherein the piston is located at least partially within the actuator housing, wherein the piston is configured to protract from a cylinder, wherein in response to the protraction, the piston is configured to rotate the pivoting lock arm from a closed position to an open position.
