  • Patent number: 11746568
    Abstract: A clamp lock includes a body, a lock mechanism coupled to the body, and a clamping member supported by the body and operatively coupled to the lock mechanism. The clamping member and body cooperatively define a slot. The clamping member is movable relative to the body by actuating the lock mechanism from a first position, in which the clamping member is configured to engage the part of the portable electronic device, to a second position, in which the clamping member is configured to disengage the portable electronic device. The clamp lock includes a spring configured to bias the clamping member toward the second position. The slot includes an opening at an outer periphery of the body and an inner channel located inward of the opening. The opening has a first height and the inner channel has a second height that is larger than the first height.

  • Publication number: 20230160236
    Abstract: A security apparatus for a portable electronic device includes a lock mechanism. A lock cylinder is configured to be rotated by a key. A cam member is coupled to the lock cylinder for rotation with the lock cylinder between an engaged position and a disengaged position. A first finger and a second finger are configured to be inserted into an aperture of the portable electronic device. The plunger is positioned between the first finger and the second finger. A user input member coupled to the plunger is selectively actuatable to move the plunger relative to the first and second fingers. When the cam member is in the engaged position, the user input member is precluded from moving from a first position to a second position. When the cam member is in the disengaged position, the user input member is capable of moving from the first position to the second position.

  • Publication number: 20220170297
    Abstract: A security anchor for a portable electronic device having an opening includes a body configured to be engaged by a lock head of a lock, a first engagement element extending from the body and configured to be inserted into the opening of the portable electronic device, a second engagement element extending from the body and configured to be inserted into the opening of the portable electronic device, and a plunger positioned between the first engagement element and the second engagement element. The plunger is linearly slidable and subsequently rotated relative to the body to expand apart the first and second engagement elements.

  • Patent number: 10982468
    Abstract: A clamp lock for securing a portable electronic device includes a body having a slot configured to receive part of the portable electronic device, a lock mechanism supported by the body, and a clamping member supported by the body and operatively coupled to the lock mechanism. The clamping member is movable relative to the body by actuating the lock mechanism between a first position, in which the clamping member extends into the slot and is configured to engage the part of the portable electronic device, and a second position, in which the clamping member is configured to disengage the portable electronic device. The clamp lock further includes a security member coupled to the body and configured to be coupled to an immovable object.
