Firearm trigger lock
View Patent ↗A trigger lock for a gun having a trigger and a trigger guard. The trigger lock has a first housing part and a second housing part and at least one of the parts includes a shackle which is insertable through the trigger guard so that the housing parts are on opposite sides of the trigger guard and so that the shackle prevents actuation of the trigger. A latch is mounted to one of the housing parts and movable between a locked and an unlocked position. In its locked position, the latch engages the shackle and secures the housing parts together. Conversely, in the unlocked position, the latch releases the shackle so that the housing parts may be separated from each other. A fingerprint scanner on one of the housing parts generates an output signal when swiped by a fingerprint. That signal is received by a processor programmed to identify one or more authorized users of the gun and, when the authorized user fingerprint swipe is identified, activates a mechanism to move the latch to the unlocked position.
1. A trigger lock for a gun having a trigger and a trigger guard comprising:
a first housing part and a second part, said housing parts being completely separable from each other, at least one of said parts having a shackle insertable through the trigger guard and against or into the other housing part so that said housing parts are on opposite sides of the trigger guard and so that said shackle prevents actuation of the trigger,
a first latch mounted to said first housing parts and pivotal between a locked and an unlocked position,
wherein in said locked position, said first latch engages a fixed latch in said second housing part and secures said housing parts together, and
wherein in said unlocked position, said first latch releases said fixed latch so that said housing parts may be completely separated from each other,
a fingerprint scanner mounted in said first housing part which generates an output signal when swiped by a fingerprint,
a processor contained in said first housing part which receives the output signal from the scanner when swiped, said processor programmed to identify an authorized user(s) of the gun and, when the authorized user is identified, activate a mechanism to move said latch to said unlocked position.
2. The trigger lock as defined in claim 1 wherein said latch moving mechanism comprises a solenoid.
3. The trigger lock as defined in claim 1 and comprising a transmitter, said processor being connected to said transmitter and activating said transmitter to transmit a signal when said sensor is swiped by someone other than the authorized user(s).
4. The trigger lock as defined in claim 3 wherein said transmitter transmits a Wi-Fi signal.
5. The trigger lock as defined in claim 3 wherein said transmitter transmits a Bluetooth signal.
6. The trigger lock as defined in claim 3 wherein said transmitter transmits a text message.
7. The trigger lock as defined in claim 3 wherein said transmitter transmits an email.
8. The trigger lock as defined in claim 1 and comprising an output port connected to said processor, said processor programmed to store at least a plurality of prior swipes of said sensor and output to said output port a history of prior swipes of the sensor upon command by the authorized user(s).
