Combination lock

摘要

In accordance with one aspect of the invention, a kicker arm-pawl lock mechanism rotates a number one wheel of a combination lock a predetermined distance to require resetting each number of a combination during lock manipulation. A drive cam-travel arm and bolt lock mechanism assures complete scrambling of the combination by requiring rotation of all wheels prior to bolt extension into a locked position. Another aspect of the invention includes a lock lever and drive cam mechanism which requires opening of the combination lock once a combination has been correctly dialed. A lock lever and pivoting pawl lock mechanism prevents lockout conditions by diverting forces applied to the combination lock bolt to the lock casing rather than the lock lever.
