<P>PROBLEM TO BE SOLVED: To provide a lock capable of being easily shut and incapable of being easily opened, and a door structure. <P>SOLUTION: A lock 1 having a main lock 2 and at least one auxiliary lock 3 fixed to one door 8 comprises a coupling mechanism 4 capable of locking the door by interlocking the auxiliary lock 3 with the main lock 2. The coupling mechanism 4 can individually open each of the main lock 2 and the auxiliary lock 3 without making an unlocking operation of the auxiliary lock 3 synchronous with that of the main lock 2. The coupling mechanism 4 comprises coupling pieces 5 and 6, and the main lock 2 and the auxiliary lock 3 are coupled together by means of the coupling pieces 5 and 6. When the main lock 2 is shut, the coupling piece 6 pushes a part of the auxiliary lock 3 to shut the auxiliary lock 3. When the auxiliary lock 3 is opened, the coupling piece 6 is deformed by being pushed by the part of the auxiliary lock 3, so that the coupling pieces 5 and 6 cannot push the main lock 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
