The mechanism includes a lifter configured to be inserted into a rear portion of the gun proximate the gun's bolt latch bar. A lever is coupled to the lifter and is configured to lift the lifter and the bolt latch bar as the gun reciprocates during firing. An electronic actuator, such as a solenoid, is configured to drive the lever to responsively lift the lifter bar, wherein the mechanism is configured to reciprocate with the gun as it is firing.

Description

    PRIORITY CLAIM
  • This application claims priority under 35 U.S.C. 119(e) of U.S. Provisional Patent application Ser. No. 62/061,680 filed Oct. 8, 2014 entitled GAU-21 TRIGGER, the teachings of which are incorporated herein in their entirely.
    • TECHNICAL FIELD
  • This disclosure is directed to an electronic trigger mechanism for a gun, and more particularly for a GAU-21 gun.
    • BACKGROUND
  • A legacy mount for some weapons, such as a GAU-21 belt fed .50 caliber machine gun, only allows the weapon to be fired mechanically by a user. This may be because the gun reciprocates during firing. The GAU-21 gun is a machine gun typically used in aircraft or on vehicles.
    • SUMMARY
  • This disclosure provides a mechanism configured to be coupled to a gun to electronically fire the gun, such as a GAU-21 gun, from a location remote from the gun. The mechanism includes a lifter configured to be inserted into a rear portion of the gun proximate the gun's bolt latch bar. A lever is coupled to the lifter and is configured to lift the lifter and the bolt latch bar as the gun reciprocates during firing. An electronic actuator, such as a solenoid, is configured to drive the lever to responsively lift the lifter bar, wherein the mechanism is configured to reciprocate with the gun as it is firing.

  • FIG. 10 illustrates the rearward moving bolt (not shown), where the bolt hits the bolt latch pawl flap and knocks it off the limit of travel pawl.
    •  DETAILED DESCRIPTION
  • Referring to FIG. 1, there is shown a perspective view of a conventional GAU-21 gun at 10. According to this disclosure, an actuating mechanism 20 is mounted to the gun 10 so that the mechanism 20 reciprocates with the gun 10 when fired. The mechanism 20 is mounted such that the gun's bolt latch bar is raised to fire the gun electronically.
  • Referring to FIG. 2, there is shown an enlarged perspective view of the actuating mechanism 20 mounted to the back of gun 10.
  • FIG. 3 is a top view of the mechanism 20 and a back plate 24 of gun 10. FIG. 4 is a left hand angled view of the mechanism 20 seen to comprise a solenoid 22 mounted to a body comprising a back plate trigger block 34. The back plate trigger block 34 is mounted to the gun's back plate 24 by inserting a front portion of the trigger block 34 into a square cutout of the back plate 24 and locking it in place using a ball lock pin 50 that extends through the trigger block 34 and the back plate 24.
  • FIG. 5 illustrates mechanism 20, where the gun's back plate, the back plate trigger block, and the ball lock pin are all hidden for clarity. The solenoid 22 is configured to pull a bell crank 26 using a clevis 28 which creates a mechanical advantage. The bell crank 26 is attached to a sliding bolt latch lifter 30 at the forward end of the mechanism 20. The lifter 30 has a vertically extending member comprising a plate 36 configured to slide in a vertical cutout channel 32 of the trigger block 34 (see FIG. 3 and FIG. 4). As the solenoid 22 actuates, the bell crank 26 rotates and causes the plate 36 of lifter 30 to move upward in the channel 32, as shown in FIG. 6 and FIG. 7. The vertical channel 32 ensures that the lifter 30 moves vertical as well, to vertically lift the gun's bolt latch bar 48. The plate 36 is configured to move parallel to the bolt latch bar 48 in the upward and downward direction.
  • A bolt latch pawl 40 is pinned to the lifter 30 and is spring loaded by a torsion spring 42 in the forward direction. As the lifter 30 moves upward, the bolt latch pawl 40 moves upward with it, pushing the limit of travel pawl 46 out of the way and lifting the gun's bolt latch bar 48, as shown in FIG. 7. When the solenoid 22 is released, the bolt latch pawl 40 is intermittently caught on the top surface of the limit of travel pawl 46 as shown in FIG. 8 and FIG. 9. The rearward traveling gun bolt hits the bottom flap of the bolt latch pawl and knocks it off the limit of travel pawl 46. The bolt latch pawl bottom flap stays pressed against the rear face of the bolt due to it being spring loaded.
  • FIG. 4 and FIG. 5 are both left hand angled views showing the bolt latch bar 48 in the resting position, where the gun is not firing. The bolt latch bar 48 is not lifted, so the gun bolt is held in the rearward position. The gun bolt face (not shown) is in contact with the bolt latch pawl flap 40. The bolt latch pawl flap 40 stays spring loaded forward by means of torsion spring 42 and the lower flap stays pressed against the gun bolt. The gun 10 is ready to be fired again in this position.
  • FIG. 6 and FIG. 7 are a left hand angled view showing the gun 10 firing. The bolt latch bar 48 is lifted by bolt latch pawl 40 by means of lifter 30 which allows the gun bolt to move freely.
  • FIG. 8 and FIG. 9 are a left hand angled view showing an intermediate position of mechanism 20, where the gun trigger is released and the gun 10 will not fire. The bolt latch pawl 40 gets caught on the limit of travel pawl 46.
  • FIG. 10 illustrates the rearward moving bolt (not shown), where the bolt hits the bolt latch pawl flap 40 and knocks it off the limit of travel pawl 46.
  • Spring 52 is the solenoid's return spring. Spring 52 forces the mechanism 20 to return back to its resting position, which is when the bolt latch lifter 30 is at its lowest position. The spring 52 must be strong enough to return the mechanism 20 to its resting position, which is not firing, but not so strong as to create too much resistance when the solenoid 22 is pulling against the spring force.
  • The foregoing detailed description is to be clearly understood as being given by way of illustration and example only, the spirit and scope of the present disclosure being limited solely by the appended claims.
