Combination padlock with secondary opening mechanism
First Claim
1. A padlock, comprising:
- a lock body;
a shackle having a long leg and a short leg, wherein the shackle is movable between a locked configuration in which the short leg is at least partially surrounded by the lock body, and a unlocked configuration in which the short leg is removed from the lock body;
a combination locking mechanism comprising at least one clutch mounted around the long leg of the shackle and configured for rotation about the long leg of the shackle, and at least one rotatable dial operatively engaged with the at least one clutch and configured to impart rotational motion upon the at least one clutch;
a tool operated locking mechanism comprising a cam and a cylinder operatively engaged with the cam, wherein the cam comprises an off-centered hole formed therein, and wherein the tool operated locking mechanism is movable between a blocking configuration in which the off-centered hole is not aligned with the short leg of the shackle and an open configuration in which the off-centered hole is aligned with the short leg of the shackle;
wherein the shackle is further movable to a combination reset configuration at least when the tool operated locking mechanism is in the open configuration, and in the combination reset configuration the at least one rotatable dial is disengaged from the at least one clutch so that the at least one rotatable dial is free to rotate without imparting rotational motion upon the at least one clutch.

Abstract
A padlock that can be locked and unlocked by both dials and a secondary opening mechanism, the padlock including a lock body, a shackle with a long leg and a short leg where the shackle can move between a locked configuration in which the short leg is secured in the lock body and an opened configuration in which the short leg is removable from the lock body. The padlock includes a combination mechanism, including a plurality of clutches mounted around the long leg of the shackle and corresponding dials mounted in the lock body each having teeth configured to engage with an extended fin of one of the clutches and a top cap seal configured to prevent the combination mechanism from being pulled apart from the lock body. A cam having a hole formed therein is configured to allow a key-user to decode a code used to unlock the padlock.
