  • Patent number: 10794092
    Abstract: The lock box includes a box, a cap, and a cable. The box includes a box opening, a lock hole, and a lock body. The cap includes a cap fixing part, a cap socket, and a restricting device. The cap fixing part is able to extend into the lock hole and be locked by the lock body when the cap covers the box opening. The restricting device has a lifting lever. One end of the cable has a cable fixing part. The cable fixing part can be inserted into the cap socket with its movement being restricted by the restricting device. A user can apply a force on the lifting lever to release the restriction on the movement of the cable fixing part by the restricting device when the cap doesn't cover the box opening.

  • Patent number: 8695384
    Abstract: A lock structure for an electrical device is provided. The lock structure includes a rotatable fastener, a lock body, an operation device, and a housing. The lock body is disposed at least partially in the housing, connected with the operation device, and includes or couples with a driving portion. When the lock body is operated to achieve an unlocked state, the lock body allows the driving portion to move the rotatable fastener. At the same time, the operation device achieves an operable status in which the operation device can move driving portion to change the orientation of the rotatable fastener, resulting in the connection/detachment of the lock structure and the electronic device. When the lock body is in a locked state, the movement of the driving portion is restricted and the operation device is not operable to directly or indirectly rotate the rotatable fastener, resulting in the secure connection of the lock structure and the electronic device.

  • Patent number: 8578743
    Abstract: A cable lock includes a belt, a lock body, a first clamp unit, a second clamp unit, and a switch unit. The belt has a buckle unit at one end thereof. The lock body has a hole for the belt to pass therethrough and a slot for receiving the buckle unit, wherein the belt and the lock body are together capable of forming a closed loop. The first clamp unit for fixing the belt in the hole is movably disposed in the lock body while the second clamp unit for retaining the buckle unit in the slot is movably disposed in the lock body. The switch unit is rotatably disposed on the lock body and capable of enabling the cable lock to operate in a locked mode, a clinched mode, or an unlocked mode. When the cable lock operates in the locked mode, the first clamp unit fixes the belt in the hole and the second clamp unit retains the buckle unit in the slot so that the closed loop has a fixed length.

  • Patent number: 8578744
    Abstract: A lock structure for an electronic device includes a housing, a securing element, an entering portion, and a lock body. The housing has a cavity and a first through hole. The securing element has a retaining portion and an extension portion extending out of the housing by the first through hole and together forming a T-shaped structure, wherein the retaining portion has a length and a width. The entering portion is capable of moving back and forth with respect to the housing and the securing portion, and is parallel to an axis of the extension portion. When the lock body is in an unlocked status, the entering portion is moveable along the extension portion; when the lock body is in a locked status, the entering portion extends out of the housing and is fixed beside the extension portion.

  • Patent number: 8528370
    Abstract: A lock includes a housing, a cable, a restrictor, and a lock unit. One end of the cable is fixed to the housing while the other end is detachably connected to the housing so as to selectively form an adjustable loop with the housing. The restrictor is rotatably disposed on the housing to selectively wedge together with the cable. The lock unit is disposed on the housing and can be selectively moved among a first position, a second position, and a third position. When the lock unit is moved toward the first position, the restrictor moves together with the lock unit to detach from the cable so as to allow the other end of the cable to disassemble from the housing. When the lock unit is moved to the second position, the restrictor restricts the cable to move toward a specific direction so as to shrink the adjustable loop. When the lock unit is moved to the third position, the restrictor wedges together with the cable, so that the length of the adjustable loop is fixed and not adjustable.

  • Patent number: 8297086
    Abstract: A loop connector and a cable lock having the loop connector are provided. The cable lock includes a cable, a lock body, and the loop connector. The lock body has a lock unit and a restricting unit. The lock unit can restrict or release the restricting unit to allow the restricting unit to movably restrict or release the cable. The cable thereby extends or retracts in this manner. The loop connector has a connector body that includes a first through hole and a second through hole. The first through hole and the second through hole are adjacent to each other, wherein the normal direction of the cross section of the first through hole is perpendicular to the normal direction of the cross section of the second through hole. When the cable passing through the lock body passes through the loop connector, the cable forms a plurality of loops at the lock body with the loop connector and the lock body to secure and protect one or more articles from being stolen.

  • Patent number: 8087274
    Abstract: A lock structure including an activation device, a combination lock, and a setting device is provided. The combination lock has a plurality of dials, a shaft passing through the dials, and a plurality of first gears disposed on one side of each dial. Each first gear further includes a missing tooth. One end of the shaft is connected to the activation device. The setting device has a plurality of second gears corresponding to the first gears and a setting shaft, wherein one end of the setting shaft passes through the second gears and the other end is connected to the activation device. When the activation device is activated, the second gears are driven to rotate the first gears, so that when each second gear runs free with the missing tooth of each first gear, the dials are in a predetermined position. That is, by means of the activation device and the setting device, the dials of the combination lock can automatically return to the predetermined position after opening or closing the lock.
