The invention provides a locking system on a cascade thrust reverser for a bypass turbojet, the reverser (20) comprising guide means (60) for the movable parts (50), and the guide means (60) comprising rails (64) attached to the movable parts (50) and tracks (62) attached to the longitudinal members

The invention provides a locking system on a cascade thrust reverser for a bypass turbojet, the reverser (20) comprising guide means (60) for the movable parts (50), and the guide means (60) comprising rails (64) attached to the movable parts (50) and tracks (62) attached to the longitudinal members (36). According to the invention, the locking system (80) comprises locks (82) located at the end (62a) of each track (62) in the opening direction (52), each lock comprising a bolt (110) capable of preventing the rail (64) moving in the opening direction (52).

What is claimed is: 1. A locking system on a cascade thrust reverser for a bypass turbojet, the reverser comprising a plurality of radial openings separated by one or more longitudinal members, the radial openings being closed by one or more movable parts moving in the closing direction, the radial openings being exposed when the one or more movable parts move in the opening direction, the reverser comprising guide means for the movable parts, the guide means comprising one or more rails attached to the movable parts and one or more tracks attached to a corresponding one of the one or more longitudinal members, and the one or more rails sliding in the one or more tracks, characterized in that the locking system comprises one or more locks located at an end of each of the one or more tracks in the opening direction, each lock comprising a bolt positioned in line with a corresponding track of the one or more tracks, the bolt being movable between a locked position and an open position, the bolt in the locked position preventing a corresponding rail of the one or more rails from moving in the opening direction when the corresponding rail is retracted into the corresponding track, and the bolt in the open position not preventing the corresponding rail from moving in the opening direction. 2. The locking system as claimed in claim 1, characterized in that one of the one or more locks is attached to one of the longitudinal members. 3. The locking system as claimed in claim 1, characterized in that one of the one or more locks is attached to the end of one of the one or more tracks. 4. The locking system as claimed in claim 1, characterized in that the one or more locks are the main locks. 5. The locking system as claimed in claim 1, characterized in that the one or more locks are back-up locks. 6. The locking system as claimed in claim 5, characterized in that each of the one or more locks comprises a body attached to a corresponding longitudinal member, the body comprising a U-shaped yoke supporting a cylindrical pivoting bolt, that part of the bolt which is situated between the wings being in line with a corresponding track and comprising a notch, said notch being in line with the corresponding track when the bolt is in the open position, said notch then allowing a corresponding rail to pass as it moves along the corresponding track, and the locking system also comprising control means for operating the bolt between the locked position and the open position. 7. The locking system as claimed in claim 6, characterized in that the control means comprise an actuator attached to the assembly formed by the one or more movable parts and the one or more rails, a lever attached to the bolt, a spring applying to the bolt a torque capable of pivoting it into the open position, a catch that automatically immobilizes the bolt when in the locked position and a motor for releasing the catch in response to a signal, and the actuator applying a force to the lever when the rail moves in the closing direction and reaches the end of its travel in the track, this force having the effect of pivoting the bolt into the closed position. 8. The locking system as claimed in claim 6, characterized in that the locking system comprises a bore and an inhibiting rod, this bore being located in the U-shaped yoke, the bore being positioned in such a way that the inhibiting rod, when present in the bore, prevents the rail moving in the opening direction. 9. The locking system as claimed in claim 8, the inhibiting rod being present in the bore, characterized in that the inhibiting rod is continued by a tail of sufficient length to be able to pass through a hole in the cowling and thus be visible on the outside. 10. The locking system as claimed in claim 2, characterized in that the locks are the main locks. 11. The locking system as claimed in claim 3, characterized in that the locks are the main locks. 12. The locking system as claimed in claim 2, characterized in that the locks are back-up locks. 13. The locking system as claimed in claim 3, characterized in that the locks are back-up locks. 14. The locking system as claimed in claim 7, characterized in that the locking system comprises a bore and an inhibiting rod, this bore being located in the U-shaped yoke, the bore being positioned in such a way that the inhibiting rod, when present in the bore, prevents the rail moving in the opening direction.
