A latch mechanism which includes two paddles that are engaged by a lock plate. The lock plate is configured to swivel into engagement with lock portions of the paddles, thereby generally locking the paddles in place. Preferably, the lock plate engages a substantial width of the lock portions to avoid creating an undesirable asymmetrical loading condition. As a result of engaging a substantial width of the lock portions of the paddles, the locking of the paddles is robust and reliable. Preferably, the lock portions on the paddles include a retention ramp that engages corresponding structure on the lock plate. The retention ramp renders the engagement between the lock plate and paddles generally more effective. Additionally, preferably the lock plate includes an extending portion that provides a helical ramp which engages a lock assembly, wherein engagement between the lock assembly and helical ramp provides that the lock assembly can be actuated to cause the lock plate to swivel into or out of engagement with the paddles. Preferably, the lock plate is spring biased such that the helical ramp on the extending portion of the lock plate is biased into engagement with the lock assembly.
