Claims
1. A self-contained triggerplate action for low profile firearms,
comprising: components enabling the gun to open, cock the hammers
to a firing position, and as a means to reset the firearm's safety,
a hammer construction enabling higher mass as a means of creating a
more reliable action with shapes to allow rebounding and minimal
trigger pull on firing said firearm, thin film coatings as a means
to reduce friction, increase rust and wear resistance of said
firearm's components, whereby said firearm has a very low profile
to provide better characteristics for firearms shooting.
Description
BACKGROUND
Field of Invention
[0001] This invention relates to firearms and the use of a
self-contained triggerplate action to enable the manufacture of a
low profile firearm.
BACKGROUND OF THE INVENTION
Description of the Related Art
[0002] Shotgun actions have traditionally been manufactured with
the lever, for opening and closing the firearm, along with the
safety reset components on the underside of the frame's tang. This
tends to restrict the overall profile of the gun, keeping it higher
than the optimal low profile for competition shooting.
[0003] This invention improves on prior firearm's designs by
incorporating all functionality for cocking the hammers, all action
components, resetting the safety and barrel selector into the
firearm's triggerplate action. The triggerplate action is fully
removable from the frame for cleaning, servicing, and tuning these
components. This allows an exceptionally low profile shotgun that
is more ideal for competitive shooting.
SUMMARY OF THE INVENTION
[0004] This invention improves on prior firearm's designs by
incorporating all functionality for cocking the hammers, all action
components, resetting the safety and barrel selector into the
firearm's triggerplate action. The triggerplate action is fully
removable from the frame for cleaning, servicing, and tuning these
components. This allows an exceptionally low profile shotgun that
is more ideal for competitive shooting.

DETAILED DESCRIPTION OF THE INVENTION
[0027] This invention improves on prior firearm's designs by
incorporating all functionality for cocking the hammers, all action
components, resetting the safety and barrel selector into the
firearm's triggerplate action. Triggerplate components have the
ability to cock the hammers and reset the safety then return to a
neutral position allowing the shooter to take the safety off and
fire the gun. The triggerplate action is fully removable from the
frame for cleaning, servicing, and tuning these components. This
allows an exceptionally low profile shotgun that is more ideal for
competitive shooting.
[0028] FIG. 1 is an assembled side view of the frame, triggerplate
and safety selector. This shows the triggerplate 2 assembled into
the frame 1 with the safety selector 3 in place.
[0029] FIG. 2 is a side view of the triggerplate with components in
a hammer cocked and safety reset position. The triggerplate 3 in
this side view shows the relative position of key components as the
gun is opened and cocked. The cocking slide 3A is pulled forward
and engages the hammer spur 3B causing it to rotate along with the
hammer 3C to a cocked ready to fire position. During this process
the hammer spur 3B also engages the safety reset 3D that pushes the
safety selector 2 back to a "safe" position.
[0030] FIG. 3 is a side view of the triggerplate with components in
a hammer cocked and gun closed position. As the gun is closed, the
cocking slide 3A is released from the cocking cycle and returns to
a neutral position. This allows the hammer spur's 3B free-wheeling
design to let it return to a neutral position under the pressure
from the safety reset spring 3E along with the safety reset 3D.
Once these components are in a neutral position the gun can be
taken off a "safe" mode by moving the safety selector 2 forward to
fire the gun. This is a critical feature that all cocking and
resetting components can return to a neutral position once the gun
is cocked and reset.
[0031] FIG. 4 is a detailed view of the hammer and hammer spur
components. The hammer spur 3B has a engagement boss 3B-1 that fits
into the hammer slot 3C-1 and will cock the hammer 3C but the slot
is large enough to allow the hammer spur to return to a neutral
position. The hammer spur 3B is registered in position with the
hammer 3C by the engagement boss 3B-1 fitting into the hammer slot
3C-1 and the hammer spur relief hole 3B-2 fitting over the hammer
shoulder 3C-2.
[0032] FIG. 5 is a detailed view of the hammer construction which
allows the hammers to rebound and eliminate firing pin drag on
shells when opening the gun, elliptical relief on the bottom of the
hammers to remove sear spring pressure that can increase trigger
pull, and high mass construction that increases the hammer force
and reliable ignition of shell primers. The hammer 3C is composed
of a hammer shell 3C-3 and a hammer insert 3C-4. The hammer insert
is manufactured from a high-density material such as tungsten with
a mass of 1.6 times steel to create more ignition force with less
spring pressure. The insert is bonded to the shell with a high
temperature brazing foil to create a high strength impact resistant
joint that withstands firearms usage. The hammer rebound boss 3C-5
is positioned on the front part of the hammer and is engaged by the
locking slide when the gun is opened allowing both hammers to
rebound and lock behind the hammer safety 3F. This eliminates any
firing pin drag on the faces of the shells in the gun's chambers
when the gun is opened. By keeping this as a separate operation
maximum spring pressure is used to accelerate the hammers when
firing the gun for higher reliability. A hammer elliptical relief
3C-6 is located at the bottom of the hammer and rotates the sear up
once that hammer is fired so that second shot trigger pull is not
adversely affected by having to overcome the pressure of two sears
when firing the second shot.
[0033] All components have thin film coatings that enhance wear
resistance, reduce friction, and increase rust resistance. This
makes the action function more smoothly and extends its service
life.
[0034] In summary, the Self-Contained Triggerplate Action for Low
Profile Firearms has the ability to cock the hammers and reset the
safety then return to a neutral position allowing the shooter to
take the safety off and fire the gun. The action has high mass
hammers that rely on less spring force to reliably fire the gun,
separate operation hammer rebound to eliminate firing pin drag and
elliptical relief to minimize trigger pull. This allows an
exceptionally low profile shotgun that is more ideal for
competitive shooting.
