Abstract
A combination lock having a housing, a shackle, a dial, a pushbutton, and a lock assembly. The lock assembly is made of a group of rotating disks having windows that can be aligned to open the lock. When the dial is turned according to the combination of the lock, the windows become aligned so that the user can depress the pushbutton to release the shackle. The pushbutton travels in a direction that is perpendicular to the axis of rotation of the dial. When the shackle is locked again, the pushbutton returns to its original position. As the pushbutton travels back to its original position, portions of the lock assembly are turned so that the combination must be reentered in order to reopen the lock.
