## Abstract

A gun lock, for blocking the trigger of a gun, comprising a first and second armored part. The armored parts are locked to each other covering the trigger and is connected to a power source and contains switching means for switching between a locked and an unlocked state. Furthermore a biometric sensor and a processor are positioned inside one of the armored parts for processing the data from the biometric sensor and allowing unlocking if the data match data from allowed users. The locking beam and the at least one support beam is configured to be positioned on either side of the trigger inside the trigger guard when in a locked state. The two armored parts covers at least the trigger and trigger guard.

## Claims

### Claim 1

A gun lock, for blocking a trigger inside a trigger guard of a gun, comprising:
a first armored part with a first abutting side from which a locking beam with a first locking formation is protruding, and
a second armored part with a second abutting side comprising a second locking formation mating with the first locking formation,
wherein the first and second locking formations are switchable between a locked state and an unlocked state,
at least one support beam protruding from one of the first and second abutting sides and extending at least past the trigger towards the other of the first and second abutting sides,
a power source,
a switching means positioned inside one of the first and second armored parts for switching between the locked state and the unlocked state,
a biometric sensor reading biometric data of a user,
a processor positioned inside one of the first and second armored parts for processing the biometric data from the biometric sensor and allowing unlocking the gun lock if the biometric data match data from allowed users, and
wherein the locking beam and the at least one support beam are configured to be positioned on either side of the trigger inside the trigger guard when in a locked state,
wherein the first and second armored parts cover at least the trigger and the trigger guard, and, wherein the switching means is activated by a manually operated hand grip for switching the switching means between the unlocked state and the locked state and blocking means for blocking the switching means from switching from the locked state to the unlocked state.

### Claim 2 (depends on 1)

The gun lock according to claim 1 wherein the first locking formation is at least one locking pin protruding at a right angle from a cylindrical outer part of the locking beam and the second locking formation is a pipe with a longitudinal guiding track mating with the at least one locking pin and a locking track at a right angle to the longitudinal guiding track, wherein a rotational movement of the first locking formation or the second locking formation will lock the first and second armored parts together.

### Claim 3 (depends on 1)

The gun lock according to claim 1, wherein the switching means for switching between the locked state and the unlocked state comprises an electrical motor and a gear transferring movement of the motor to a rotational movement of the first locking formation or the second locking formation.

### Claim 4 (depends on 1)

The gun lock according to claim 1 wherein the blocking means comprises a rod with a pitch rack, wherein the rod mates with a blocking hole in a blocking cylinder connected to the locking beam and the hand grip and is rotatable around a same axis as the locking beam.

### Claim 5 (depends on 1)

The gun lock according to claim 1 wherein the switching means and the processor reside within the same armored part.

### Claim 6 (depends on 1)

The gun lock according to claim 1 wherein the biometric sensor is positioned outside of the first armored part and the second armored part and the sensor sends unprocessed biometric data to the processor inside the first armored part and the second armored part.

### Claim 7 (depends on 1)

The gun lock according to claim 1 wherein the first and second armored parts are attached to each other by a hinge.

### Claim 8 (depends on 1)

The gun lock according to claim 1 wherein the biometric sensor is a fingerprint sensor.

### Claim 9 (depends on 1)

The gun lock according to claim 1 wherein the at least one support beam protruding from one of the first and second abutting sides mates with corresponding support holes in the other first and second abutting side.

### Claim 10 (depends on 1)

The gun lock according to claim 1 wherein a transmitter and receiver are attached to the gun lock.
