  • Patent number: 11024107
    Abstract: A combination lock has a touch panel to receive a keypad entry code indicative of a combination code for unlocking the lock with various access levels, including a first level and second level. The combination lock is also arranged to receive the combination code from a mobile device via wireless signals. The combination lock also has an independent key-lock mechanism for unlocking the lock with a key. The mobile device has an application icon, when activated, prompting the wireless signals indicative of the combination code. The mobile device also has a deactivation icon and re-activation associated with the combination code of the first level. The deactivation icon causes the disablement of the touch panel and the key-lock mechanism when activated. The re-activation icon terminates the disablement of the touch panel and the key-lock mechanism when activated.

  • Patent number: 10443272
    Abstract: A padlock has a shackle having a long leg and a short leg, and a spindle with an extended member, the extended member engaged with the long leg of the shackle for movement together. The padlock also has a cylinder to receive a key for key operation, a stack of clutches and a plurality of dials engageable with the clutches to form a combination code, each clutch having an opening to receive the spindle. When the padlock is unlocked by the combination code, the spindle is engaged with the clutch stack for movement together along with the shackle. When the padlock is unlocked by the key operation, the spindle is disengaged with the clutch stack, allowing the spindle and the shackle to move upward relative to the clutch stack.

  • Patent number: 10221591
    Abstract: A dual locking padlock having a code locking mechanism and an overriding mechanism is disclosed. The housing has a top body as its top portion, a stack of dials and a stack of clutches mounted on a middle portion and a bottom portion having holes to receive screws from the top body for securing the housing. Dials are engagingly mounted on the clutches and only rotatable relative to the clutch when the lock is in the opened mode for changing the combination code. The housing has a spindle having a channel to store the heel of a shackle. The spindle's upward movement allows the shackle to be pulled upward to unlock the padlock. The spindle is allowed to move upward either when a correct combination code is used or when a key activates the overriding mechanism. With the overriding mechanism, the padlock can also be opened with a key.

  • Patent number: 10214942
    Abstract: A zipper lock has a combination locking system defined by dials and clutches and a key overriding mechanism. The lock has a pole to receive zipper pullers and a movable cover plate to block the pole when the lock is in the locked mode. The lock has a control plate with release slots. The control plate can be shifted only if the dials are set to the correct combination or when a correct key is used to turn a tumbler cylinder. The cover plate is engaged with a latch having a latch finger. When the lock is in the locked mode, the latch finger is blocked by the control plate, restricting movement of the latch. When the lock is in the unlocked mode, the latch finger can be moved into a release slot, allowing the latch and cover plate to move in order to clear the pole.

  • Patent number: 9890559
    Abstract: A dual locking padlock having a code locking mechanism and an overriding mechanism is disclosed. The housing has a top body, a stack of dials and clutches mounted on a bottom body, and a spindle engaging with the clutches. The spindle has a channel to store the heel of a shackle. An upward movement of the spindle allows the shackle to be pulled upward to unlock the padlock. Each dial has a plurality of teeth with slope-like surfaces to engage with the wave slots of a clutch. Clutches are rotatable relative to the spindle only when the lock is in the locked mode along with the dials. In the opened mode, a dial can be turned relative to a clutch by disengaging the teeth from wave-slots. The spindle is allowed to move upward either when a correct combination code is used or when a key activates the overriding mechanism.

  • Patent number: 9803398
    Abstract: A padlock is provided that can be locked and unlocked using a combination mechanism or a key mechanism. A padlock includes clutches that will not be turned during the lock mode or the open mode. A lock body has more than one slot to engage an extended fin of the clutch in the lock mode. An opening slot and faulty notches are located in each of the dials. In the lock mode, the turning of the dials will have no effect on the clutches. Each extended fin of the clutch is engaged in a slot of the lock body in the lock mode. The faulty notches on the dials are clearer and an intruder cannot feel the correct opening slot by turning dials to pick the combination.

  • Patent number: 9556650
    Abstract: A padlock has a shackle with a short leg and a long leg and a lock body having two partial channels to accommodate the short and long legs. Each of the short and long legs has a bolt groove to receive a bolt. The lock body also has a through channel for placing a spindle having a locking area and an unlocking groove. A plurality of dials and clutches mounted on the spindle control the spindle movement. When the padlock is in the locked mode, the spindle is located within the through channel such that the locking area pushes the bolts against the bolt grooves, preventing the shackle from being pulled upward. When dials match the combination code, the spindle can move upward to allow the bolts to move away from the bolt grooves toward the unlocking groove and the shackle can be pulled upward to unlock the padlock.

  • Patent number: 9487969
    Abstract: A combination lock having a plurality of dials and clutches arranged to control a lock shackle is disclosed. Each of the dials is mounted on a different clutch to form a dial-clutch pair. The clutch has a protrusion and the dial has an open slot dimensioned to receive a protrusion and a plurality of faulty notches. The protrusion is so located that when the lock is in the lock mode, the protrusion in each of the dial-clutch pairs is disengaged from the open slot, allowing the dial to rotate relative to the clutch. Since the clutches do not turn along with the dials and the faulty notches look similar to the open slot, it would be difficult for an intruder to pick the lock by peeking the protrusion of the clutches while rotating the dials.

  • Patent number: 8919155
    Abstract: A padlock includes a housing and a shackle positionable between an open position and a closed position. The shackle may be retained in its closed position within the housing by a latch that is operatively connected to a key locking mechanism and a combination locking mechanism. The latch may be disengaged from the shackle so that the shackle may be placed into the open position when the key locking mechanism is placed in an unlocked orientation or the combination locking mechanism is placed in an unlocked configuration. The key locking mechanism may include a cylinder configured for operative engagement with the latch, and the combination locking mechanism may include a button configured for operative engagement with the latch and a spindle configured to restrict movement of the button. In the unlocked configuration of the combination locking mechanism, the combination used for the combination locking mechanism may be reset and/or reconfigured.

  • Publication number: 20140373579
    Abstract: A padlock with a dual unlocking system, namely, a key mechanism and a combination mechanism. The key mechanism has a bolt or latch passing through a pole/pole cover secured around a portion of a shackle, the bolt in contact with the shackle so as to prevent movement of the shackle relative to the key mechanism when the key mechanism is in a locked state. The bolt/latch is able to move relative to the shackle to allow the shackle to move relative to the housing and pole so as to release the toe of the shackle from the housing when the key mechanism is in an unlocked state. The combination mechanism allows clutches to move relative to the housing into a lock open position when dials are in an opening combination that allows the pole to move relative to the housing so as to release the toe.
