Abstract:

An electronic firearm lock (10) includes a housing (18) and a locking plate (28) which are locked together rendering the trigger (12) of a firearm (16) inaccessible. The housing (18) includes a locking lever (36) which engages a sawtooth surface (34) of the locking member (32) of the locking plate (28). The lock is unlocked by entering an input code via keypad (44). The keypad (44) is illuminated prior to the pressing of any button (100) by touching two conductors (62) simultaneously by the same object, i. e. , a finger allowing the operator to see the keypad (44) before the needing to begin entering an incorrect code. An alarm transducer (82) signals both when a plurality of incorrect codes are entered, indicating an unauthorized person was attempting to access the firearm (16), and when the voltage level of the battery (74) is low.
