Abstract:
1. A combination lock for locking first and second casing halves of a suitcase, said combination lock comprising: a base mounted securely on one of the first and second casing halves; a case locking mechanism mounted on said base and operable to move between a locking position to lock the first and second casing halves, and a releasing position to release the locking action of said case locking mechanism on the first and second casing halves; a dial lock mounted on said case locking mechanism, including a lock controlling member, and operable between a locking state, in which said case locking mechanism is prevented from moving from the locking position to the releasing position by said lock controlling member, and a releasing state, in which said case locking mechanism is released from said lock controlling member and is permitted to move from the locking position to the releasing position; and a key-operated unlocking unit mounted on said case locking mechanism and including a core that is rotatable between first and second angular positions, and that is associated with said lock controlling member in such a manner that said case locking mechanism is prevented from moving from the locking position to the releasing position by said lock controlling member when said dial lock is disposed at said locking state and when said core is disposed at said first angular position, and that said case locking mechanism is released from said lock controlling member and is permitted to move from the locking position to the releasing position when said core is disposed at said second angular position; wherein said lock controlling member includes a limiting lever that is fulcrumable among a middle position, in which said case locking mechanism is prevented from moving from the locking position to the releasing position by said limiting lever, an upper position, in which said case locking mechanism is released from said limiting lever and is permitted to move from the locking position to the releasing position, and a lower position, in which said case locking mechanism is released from said limiting lever and is permitted to move from the locking position to the releasing position.
