Combination padlock

A combination lock comprising:

• a lock body;
• a shackle having long and short legs receivable in corresponding first and second shackle openings in the lock body and axially moveable between a retracted position and an extended position, the short leg being withdrawn from the lock body when in the extended position;
• a locking mechanism disposed in the lock body, the locking mechanism comprising a locking member for lockingly engaging the shackle, and a plurality of interengaging hubs each interlocking with a corresponding wheel for mutual rotation therewith about a post, wherein when each of the plurality of wheels is rotated to an unlocking orientation, the locking member is permitted to disengage the shackle to permit movement of the shackle from the retracted position to the extended position;
• a dial secured to the lock body for selective rotation of the plurality of hubs;
• and
• a camming member disposed in the lock body, the camming member being configured to be pivoted from a normal condition to a resetting condition by insertion of a tool into the lock body, to axially move the plurality of wheels along the post and out of interlocking engagement with the corresponding hubs, such that subsequent rotation of the dial selectively adjusts the rotational position of each of the plurality of wheels with respect to the corresponding hub.

• a dial secured to the lock body for selective rotation of the plurality of hubs;
• and
• a camming member disposed in the lock body, the camming member being pivotable around the post from a normal condition to a resetting condition to axially move the plurality of wheels along the post and out of interlocking engagement with the corresponding hubs, such that subsequent rotation of the dial selectively adjusts a rotational position of each of the plurality of wheels with respect to the corresponding hub.

• a locking mechanism disposed in the lock body, the locking mechanism comprising:
• a locking member;
• a sliding member axially movable with respect to the locking member and having a ramped surface configured to hold the locking member in locking engagement with a corresponding notch in the shackle when the sliding member is in a locked position, and further configured to allow the locking member to disengage from the shackle when the sliding member is in an unlocked position, to permit movement of the shackle from the retracted position to the extended position;
• and
• a plurality of cams rotatable about a post, wherein when each of the plurality of cams is rotated to an unlocking orientation, unlocking features disposed on each of the plurality of cams align with the sliding member to permit axial movement of the sliding member from the locked position to the unlocked position;
• and
• a dial secured to the lock body for selective rotation of the plurality of cams.

• a first rotatable mechanism, rotatable about a first axis in response to user manipulation of the lock;
• and
• a second rotatable mechanism, rotatable about a second axis spaced apart from the first axis, in response to rotation of the first rotatable mechanism, the second rotatable mechanism including a recess that permits axial movement of the sliding member from the locked position to the unlocked position when the recess is aligned with the sliding member.
