Computer security locks and system therefor

A lock assembly for preventing theft of an electronic mobile device (EMD) having a security cavity formed in an outer wall of the EMD, wherein the outer wall is formed of metal and has a thickness of less than 2.5 millimeters measured from a front surface to a rear surface of the outer wall, and the security cavity has an opening thereinto at the front surface that is generally rectangularly shaped with arcuately-shaped left and right sides, the security cavity having left and right outwardly flaring side walls extending away from the opening to the rear surface of the outer wall, the lock assembly comprising:

• a lock body including a user-controlled locking mechanism;
• a first locking element that protrude from a front wall of the lock body, and the first locking element is configured to be insertable into the security cavity via the opening and has an arcuately-shaped side that is complementary in shape to the left outwardly flaring side wall of the security cavity and configured to be laterally and slidingly movable in the security cavity to tightly engage the left outwardly flaring side wall of the security cavity, and the first locking element is configured to prevent insertion thereof beyond the outer surface of the cavity;
• a second locking element that is insertable into the security cavity via the opening and has an arcuately-shaped side that is complementary in shape to the right, outwardly flaring side wall of the security cavity and a configuration that prevents insertion of the first locking element beyond the outer surface of the cavity, the first and second locking elements cooperating structurally with each other to become wedged inside the security cavity in manner that prevents separation of the lock body from the EMD while the first and second locking elements are positioned inside the security cavity, and wherein the arcuately-shaped sides of the first and second locking elements extend over an arc angle in the range of 120 to 180 degrees;
• and
• a cable assembly coupled to the lock body and configured to enable affixing the lock body to an immovable object, whereby when the lock body is affixed to the EMD via the locking elements being engaged with the security cavity, theft of the EMD is prevented.
