Abstract
A combination lock includes an outer case with an inner case received therein and the outer case has a chamber which communicates with a passage in which a latch is received. A spring is mounted to the latch and provides a force to move the latch in a direction away from the chamber. A front unit having two disks is located in the first chamber and a rear unit having two disks is located in the second chamber. The two disks of the front unit drive each other and the two disks of the rear unit drive each other. A first dial plate drives one of the disks of the front unit and a second dial plate drives one of the disks of the rear unit. When the notches are in alignment with each other, the end piece of the latch can pass through the notches and the lock is unlocked.
