Claim Text:
1. A combination disc padlock comprising: a housing having a disc shape having a perimeter and comprising a slot formed therein; a shackle positioned within a portion of the housing and movable between an open position and a closed position, the shackle having a curved shape with a first end positioned within the housing and a second end which can be exposed from the housing when the combination disc padlock is in an unlocked configuration and the shackle is in the open position; a combination code core locking mechanism comprising a lock body, a spindle positioned within the lock body, at least one clutch positioned concentrically with the spindle, at least one dial operatively engaged with each of the at least one clutches and positioned concentrically with the at least one clutch, and a locking ball operatively connected to the spindle; and an actuation mechanism operatively coupled to the shackle, and configured to permit movement of the shackle between the open position and the closed position when the combination disc padlock is in the unlocked configuration; wherein the combination code core locking mechanism is configured to operate the combination disc padlock between the unlocked configuration and a locked configuration, and configured to control movement of the shackle between the open position and the closed position; wherein the at least one clutch is retained concentrically about the spindle such that movement of the at least one clutch is coextensive with movement of the spindle; wherein each clutch of the at least one clutches comprises at least one extended fin, and the lock body comprises at least one blocking wall having at least one extended fin receiving slot formed therein and dimensioned to receive a corresponding extended fin of one of the clutches so that when all of the extended fin receiving slots and extended fins are aligned with each other, each of the clutches may pass through a corresponding blocking wall of the at least one blocking wall and the spindle can be moved in a direction away from the locking ball thereby permitting the locking ball to be pushed by a curved cutout formed in the shackle such that the locking ball is forced to move out of the curved cutout and thereby permitting movement of the shackle into the open position; wherein each of the at least one dials comprises at least one tooth configured for engagement with the at least one extended fin of the corresponding at least one clutch; wherein a combination code for the combination code core locking mechanism can be reset or reconfigured when the shackle is in a reset position; wherein when the shackle is in the reset position each of the at least one tooth of the at least one dials are disengaged from the at least one extended fin of the corresponding at least one clutch so that each of the at least one dials may be rotated while positioned concentrically about the corresponding at least one clutch without also causing rotation of each of the at least one clutches; and wherein when the shackle is moved back into the closed position the at least one extended fin of each of the at least one clutches re-operatively engages with the corresponding at least one tooth of the at least one dials resulting in the combination code for the combination code core locking mechanism being reset or reconfigured.
