  • Patent number: 9383153
    Abstract: A striker-fired firearm in one embodiment includes a trigger assembly including a trigger and trigger bar supported by a frame, a rotatable sear operable to hold a spring-biased striker in a cocked ready-to-fire position, and a rotatable sear blocker operable to prevent rotation of the sear. The trigger bar is operably linked to the sear and blocker such that pulling the trigger rotates the sear and blocker. When the blocker is in a blocking position, the blocker engages and prevents movement of the sear and release of the striker in the absence of a trigger pull. When the blocker is in a non-blocking position effectuated by pulling the trigger, the blocker disengages the sear which rotates and releases the striker to fire the firearm.

  • Patent number: 8966802
    Abstract: A trigger assembly has a sear with a stop surface engageable with a reciprocating component for holding the reciprocating component in a cocked configuration. The sear also has a sear cam engageable with a lever movably mounted within the assembly. A trigger is movable into and out of engagement with the lever. Pulling the trigger moves it out of engagement with the lever and releases the sear. A trigger return pendulum has a trigger cam engageable with the trigger, a lever cam engageable with the lever, and a head cam follower engageable with the reciprocating component. Motion of the reciprocating component acting through the head cam follower of the trigger return pendulum forces the lever cam into engagement with the lever and the trigger cam into engagement with the trigger to return the lever and the trigger to a configuration of engagement between the trigger and the lever.

  • Patent number: 8893420
    Abstract: A battery-powered trigger-locking device, which is configured to be disposed on a gun with a trigger for firing, includes a data receiver, a data memory and a logic device for determining whether data received by the receiver is the same, or substantially the same, as data stored in the memory. If a data match is indicated, the logic device causes an electromagnetic device to move a trigger-locking member to an unlocked position, permitting the gun to be fired. A separate electronic gun key is provided to transmit gun unlock data to the data receiver of the trigger-locking device. This gun unlock data may be a password, a long pseudo-random number or biologic data identifying the gun owner or some other person who is licensed or otherwise authorized to fire the gun.

  • Patent number: 8850944
    Abstract: A gun safety device on a gun automatically prevents the gun from firing when it is inside a registered area, which includes: a positioning device for determining the geographic position of a gun; a data processing device for identifying whether the gun is located within a registered area by comparing the gun's position with the stored geographic positions of the registered areas, and for generating a disable signal when the gun is identified to be inside a registered area; and a safety seizer operable to prevent the gun from discharging in response to receiving the disable signal from the data processing device. The automatic gun safety device may further include a communication device for communications with external networks. Optionally, the data processing device sends the gun's location to a monitoring center. The practice of this invention will ensure the community safety meanwhile defend the constitutional right of gun ownership.

  • Patent number: 8677665
    Abstract: A trigger may be pivotally connected to a frame at or near the top of the trigger. A sear transfer bar may be further provided and is pivotally connected to the frame. The pivot in the trigger is higher within the frame as compared to the pivot of the sear transfer bar. Two balls can be between the trigger and the sear transfer bar. The top of the sear transfer bar has a sear contact. Pulling the trigger in a first direction causes the trigger to rotate in a first direction. The sear transfer bar rotates under force of the trigger. The sear transfer bar and the trigger may rotate in opposite directions. The sear will drop when the sear contact of the transfer bar ceases engagement with the sear, causing the firearm to fire. The trigger assembly has a control arm extending beyond the trigger assembly frame.

    Abstract: The present invention relates to a safety device for a firearm with a trigger bar in said firearm. The trigger bar moves in response to a pulling of a trigger. An actuator in said firearm is adapted to actively move said trigger bar between a first position and a second position. The trigger bar engages in the trigger induced movement with a hammer link for releasing a hammer and firing a cartridge bullet when the trigger bar is in the first position or first state. However, said trigger bar does not engage in the trigger induced movement with the hammer link, such that the cartridge bullet is not fired, when the trigger bar is in the second position or state.

  • Patent number: 8495832
    Abstract: The invention discloses a safety mechanism of a handgun which depends on a magazine and which prevents the triggering of a handgun when the magazine is removed. Additionally, a mechanism enables handgun disassembly without need for the triggering after the magazine has been removed from the handgun. A safety mechanism is positioned inside the handgun receiver; including a magazine, sear catcher, sear catcher spring, grip safety pin, sear, sear pin, firing pin safety lever and firing pin. When the magazine is inserted into the handgun, the sear catcher is pushed into position in which it cannot block the firing pin safety lever nor catch the sear. When the magazine is removed from the handgun, the sear catcher spring pushes the sear catcher into position in which it blocks the firing chain by blocking the firing pin safety lever.

  • Patent number: 8250799
    Abstract: Applicants have disclosed an improved trigger assembly for firearms, and a related method, to avoid premature firing after an unintentional trigger pull, especially where light trigger pulls have previously been set. In the preferred embodiment, Applicants' trigger assembly has two non-coaxial triggers: a slotted primary trigger and a secondary trigger which can pivot into the slot. During an intentional trigger pull, the shooter's finger initially pushes against the secondary trigger until it pivots and nestles within the primary trigger's slot. Continued pulling on both the secondary and primary triggers causes a sear to fall off the primary trigger and the firearm to discharge. In an unintentional trigger pull, where the secondary trigger is not pulled back enough to nestle within the primary trigger's slot, a protrusion on the secondary trigger blocks the sear from falling, thereby avoiding discharge.
