ABSTRACT:
An electronic lock for use with lockers assigned for transitory or permanent use, has a keypad for entering a preselected sequence of digits. Programmable for each use in the transitory mode, the lock shifts a latch to locked position on a first entry of a sequence chosen by the user, and retracts the latch to unlocked position when the same sequence is reentered by the user. A subsequent user of the locker when unlocked can enter any sequence of digits desired. In the mode of a longer term assigned locker, the electronic lock is programmed by, for example, a student, and the same combination is retained as long as desired. In this mode, the selected sequence is used only to unlock, with the latch or mortise being spring-biased. The construction of the electronic lock is modular, easily fitting on nearly all contemporary locker designs, retained by only a few screws. An outer housing on the outside of the locker door has an electrical plug-in connection through the door with an inner housing at the inside of the door, and the housing portions can be changed to opposite hand use. Power input ports preferably are included on the front of the outer housing to power the lock in the event of battery failure, and in addition, an audible beep occurs when batteries are low. An LED indicator can be included for status, as can an infrared reader for instant reprogramming of a large bank of lockers such as in a school.
