Dual locking combination padlock with decode function
A padlock comprising a lock body, a combination mechanism to control the movement of the cam-spindle vertically, a key mechanism to control the movement of the cam-spindle rotationally, more than one clutch that is mounted in the cam-spindle which controls the vertically movement of the cam-spindle, wherein the cam-spindle is configured to control the locking and unlocking of the combination mechanism, and wherein more than one dial is mounted in the lock body, a locking bolt contacts the shackle, and the shackle has a long leg and a short leg with a bolt-receiving-cutout.
1. A padlock comprising:
a lock body,
a shackle,
a pair of locking bolts configured for engagement with the shackle, wherein the shackle has a long leg for engagement with one of the pair of locking bolts and a short leg for engagement with the other of the pair of the locking bolts,
a combination mechanism to control the movement of a cam-spindle vertically, and
a key mechanism to control the movement of the cam-spindle rotationally,
wherein the combination mechanism comprises more than one clutch that isare mounted in the cam-spindle which controls the vertically movement of the cam-spindle,
wherein the cam-spindle is configured to control the locking and unlocking of the combination mechanism, and
wherein the combination mechanism comprises more than one dial are mounted in the lock body,
wherein the cam-spindle has at least two sets of bolt-notches, one set of bolt notches controlled by the combination mechanism and the other set of bolt notches controlled by the key mechanism,
wherein one bolt notch of the set of bolt notches controlled by the combination mechanism is configured for engagement with one of the pair of locking bolts, and the other bolt notch of the set of bolt notches controlled by the combination mechanism is configured for engagement with the other of the pair of locking bolts, and
wherein the bolt notches for the combination mechanism are positioned substantially perpendicular on the cam-spindle to the bolt notches for the key mechanism.
2. The padlock according to claim 1 , wherein the cam-spindle is split in two parts.
3. The padlock according to claim 1 , wherein the bolt-notches for the combination mechanism are different than the bolt-notches for the key mechanism.
4. The padlock according to claim 1 , wherein the cam-spindle has a spindle-protrusion for each of the more than one clutches, which each spindle-protrusion aligns with an opening-gap of the corresponding clutch of the one more than one clutches to open the padlock.
5. The padlock according to claim 1 , wherein the cam-spindle has a direction fin assembled in a rotational-vertical channel of the lock body and controls an amount of rotation of the key mechanism and an amount of vertical movement by the combination mechanism.
6. The padlock according to claim 5 , wherein the cam-spindle contains a spindle-tail which is connected to a transfer cam which is then connected to the cylinder for key mechanism.
7. The padlock according to claim 1 , wherein the padlock further comprises a decode mechanism.
8. The padlock according to claim 7 , wherein the decode mechanism can be activated when the padlock is in an open mode.
9. The padlock according to claim 8 , wherein the decode mechanism has a decode-bar and a decode-plate, wherein the decode-bar contains a pin which can drive a slope of the decode-plate rightward to push thea decode finger of the decode plate toward a decode slot of the lock body, and wherein as the decode-bar is pushed, a rotation of the clutch in a certain rotation causes a decode fin to be in contact with the decode-finger to determine a lost code.
10. The padlock according to claim 1 , wherein a transfer cam is connected between the cylinder and the cam-spindle to control the rotational movement of the cam-spindle to control the padlock open and closing positions.
