US12704339 - Sear assembly for weapons

A sear assembly for a weapon, the weapon comprising a hammer adapted to contact with the sear assembly and a trigger disconnected from the sear assembly, the sear assembly comprises a sear for mechanically engaging a sear surface on the hammer, a lever mechanically coupled by one end to the sear, the lever comprising a contact surface that causes the rotation of the sear, an actuator that actuates the lever by means of a cam, and a trigger sensor that is configured to determine if the trigger is pulled. In this regard, the trigger sensor is a coil. The sear assembly comprises a firing state and a safe state.

The patent describes a sear assembly for firearms that includes a hammer, a lever, and a trigger sensor, allowing for both firing and safe states. The assembly operates by using an actuator and cam mechanism to control the sear’s engagement with the hammer, enabling or preventing the weapon from firing based on the trigger’s status.

Claim 1

1 . A sear assembly for a weapon, the weapon comprising a hammer adapted to contact with the sear assembly and a trigger disconnected from the sear assembly, wherein the sear assembly comprises: a sear for mechanically engaging a sear surface on the hammer; a lever mechanically coupled by one end to the sear, the lever comprising a contact surface that causes the rotation of the sear; an actuator that actuates the lever by means of a cam; and a trigger sensor that is configured to determine if the trigger is pulled, wherein the trigger sensor comprises a coil, wherein the sear assembly comprises: a firing state, wherein the actuator actuates the lever by means of the cam such that the contact surface of the lever causes the rotation of the sear in a counterclockwise direction, such that the sear disengages the sear surface on the hammer allowing at least a shot to be fired when pulling the trigger; a safe state, wherein the actuator actuates the lever by means of the cam such that the contact surface of the lever causes the rotation of the sear in a clockwise direction, such that the sear engages the sear surface on the hammer impeding a shot to be fired when pulling the trigger. a sear for mechanically engaging a sear surface on the hammer; a lever mechanically coupled by one end to the sear, the lever comprising a contact surface that causes the rotation of the sear; an actuator that actuates the lever by means of a cam; and a trigger sensor that is configured to determine if the trigger is pulled, wherein the trigger sensor comprises a coil, wherein the sear assembly comprises: a firing state, wherein the actuator actuates the lever by means of the cam such that the contact surface of the lever causes the rotation of the sear in a counterclockwise direction, such that the sear disengages the sear surface on the hammer allowing at least a shot to be fired when pulling the trigger; a safe state, wherein the actuator actuates the lever by means of the cam such that the contact surface of the lever causes the rotation of the sear in a clockwise direction, such that the sear engages the sear surface on the hammer impeding a shot to be fired when pulling the trigger.
