  • Padlock assembly
    Patent number: 8806905
    Abstract: A padlock includes a lock body, a shackle assembled with the lock body, a lock subassembly disposed in a cavity in the lock body, and a shackle retainer assembled with the lock body. The lock subassembly is operable between a locked position securing the shackle in a closed position and an unlocked position permitting movement of the shackle to an open position. The shackle retainer extends into a first shackle bore and is received in a recess in a first leg of the shackle. When the shackle is in the open position, the lock subassembly is manipulable to be moved from a first position to a second position to generate a space in the cavity aligned with the shackle retainer, such that the shackle retainer is extendable into the space for disengagement of the shackle retainer from the first shackle leg recess.

  • Combination lock
    Patent number: 8769999
    Abstract: A combination lock includes a lock body, a shackle, a blocker, and a plurality of dials. The shackle includes a long leg and a short leg. The blocker is disposed within the lock body and is movable in an axial direction between a shackle securing position, in which the blocker causes at least one locking member to engage with the shackle, and a shackle releasing position, in which the blocker allows the at least one locking member to disengage from the shackle for separation of the short leg from the lock body. Each dial includes a recess disposed on an outer periphery of the dial. When each dial is rotated to an unlocking orientation, each recess aligns with a corresponding dial engaging portion of the blocker, allowing the blocker to move from the shackle securing position to the shackle releasing position.
