Abstract: A locking mechanism is provided. The locking mechanism includes a mounting plate that carries a locking hook. The locking hook is pivotal with respect to the mounting plate and may be pivoted from an unlocked position to a locked position. A motor is in communication with a locking hook, and is capable of causing the locking hook to be pivoted to the locked position. The locking mechanism may be opened by use of an electronic key, and may contain electronics capable of recording the date and time a particular key was used to open the locking mechanism. Also, the locking mechanism may be capable of being locked without the use of the motor when the motor is disabled due to power disruption or other circumstances.

Abstract: A automatic locking and unlocking device for effecting the locking engagement of a lock stud within a stud receiving fixture. The lock device of the present invention is adapted for locking a movable closure member relative to a stationary member, such as a vending machine door to a cabinet, and provides a quick open and quick close locking feature. The locking device includes a lock stud fitted with a t-handle at its outer end, and a nose portion inner end, the nose portion having a pair of opposed pin engagement ledges formed therein adjacent the nose portion, and provided with male threads positioned adjacent to and forwardly of the pin engagement ledges. The stationary member is provided with a stud receiving lock housing which contains a stationary cam sleeve, a rotatable cam sleeve which reciprocates relative to the stationary cam sleeve, and a coupling which is positioned anteriorly of the rotatable cam sleeve.
