Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit of U.S. Provisional
Application No. 61/295,436 entitled "TRIGGER INSERT SYSTEM," filed
Jan. 15, 2010, which application is hereby incorporated by
reference in its entirety.
BACKGROUND
[0002] In general, trigger systems are supplied for rifles and
pistols. For certain platforms, such as in one form the AR 15,
trigger systems are stock whereby aftermarket triggers can be
provided as well as advanced trigger systems initially installed
OEM.
[0003] Other insert trigger systems have had difficulty in
maintaining proper relationships of the components for reliable
operation of the triggers.
SUMMARY
[0004] Accordingly, a trigger system is disclosed. One embodiment
comprises a trigger module with a hammer within the housing, the
hammer having an impact region, a base region including a hammer
pivot location, a hammer sear surface and a hammer disconnector, a
trigger within the housing, the trigger having a trigger sear
surface to engage the hammer sear surface, the trigger being
pivotably connected to the housing with a pin, a disconnector
pivotably connected to the pin, the disconnector having a
disconnector sear to engage the hammer disconnector, the
disconnector further having a disconnector adjuster configured to
adjust a rotational distance between the disconnector and the
trigger, and a safety coupled to the trigger, the having a safety
adjuster to adjust the play between the safety and the trigger.
[0005] Another embodiment comprises a trigger module with a
housing, a hammer within the housing, the hammer having an impact
region, a base region including a hammer pivot location, a hammer
sear surface and a hammer disconnector, a trigger within the
housing, the trigger having a trigger sear surface to engage the
hammer sear surface, the trigger being pivotably connected to the
housing with a pin, and a disconnector pivotably connected to the
pin, the disconnector having a disconnector sear to engage the
hammer disconnector, the disconnector further having a disconnector
adjuster configured to adjust a rotational distance between the
disconnector and the trigger.
[0006] This Summary is provided to introduce concepts in a
simplified form that are further described below in the Detailed
Description. This Summary is not intended to identify key features
or essential features of the claimed subject matter, nor is it
intended to be used to limit the scope of the claimed subject
matter. Furthermore, the claimed subject matter is not limited to
implementations that solve any or all disadvantages noted in any
part of this disclosure.

DETAILED DESCRIPTION
[0013] As shown in FIG. 1, there is a trigger module 20 comprising
a housing 22, a safety 24, and a trigger assembly 26. The axis
system 10 has a longitudinal axis 12, a vertical axis 14 and a
lateral axes 16. In general, the axis system 10 is used to
generally refer to orientations of the components and not
necessarily limiting to certain specific orientations. For example,
the trigger module need not always be vertically orientated.
[0014] As shown in FIG. 3, the trigger assembly 26 comprises a
trigger 28, and a disconnecter 30. In one form the disconnecter 30
shares a common center at 32 where a pin passes therethrough. In
general, this pass-through pin engages the housing of an AR 15. As
further shown in FIG. 3, the longitudinally forward location 34 of
the trigger 28 provides a trigger sear surface 36 which is
operatively configured to engage the hammer sear surface 46. The
hammer 38 is pivotally attached at the hammer pivot location 40.
The hammer has a base region 42 and an impact region 44. Located at
the base region is the hammer sear surface 46 which, as mentioned
above, is configured to engage the trigger sear service 36 to hold
the hammer in a high-energy state position, otherwise referred to
as the cocked position. A spring member, such as a coil spring, is
operably attached to the hammer 38 so as to bias the hammer in a
longitudinally forward region.
[0015] As shown in FIG. 5, there is a cross-sectional view of the
trigger module 20 taken at line 5-5 of FIG. 2. As shown in FIG. 5,
the disconnecter 30 has the common center 32 where the disconnecter
rotates therearound. The disconnecter 30 is provided with a
longitudinally rearward region 50 and a longitudinally forward
region 52. Located in the longitudinally rearward region is a
surface defining recess 54. The surface defining a recess 54
defines a spring holding location 56.
[0016] The trigger 28 is provided with a longitudinally rearward
region 60 that is provided with a surface defining a recess 62
which defines a trigger spring holding location. A sear spring is
configured to fit within the trigger spring holding location 62 and
the spring holding location 56 to rotate the sear 30 in a clockwise
direction (which is referenced to FIG. 5) with respect to the
trigger 28.
[0017] In operation, the disconnecter sear 70 is configured to
engage the hammer disconnecter 72 when the trigger 28 is pressed.
In other words, when the trigger is pressed fully rearwardly the
hammer will initially fall, and with a semi-automatic rifle, be
cocked rearwardly. As the hammer is cocked rearwardly while the
trigger is depressed, the hammer disconnecter 72 will slide over
the disconnecter sear 70 and the disconnecter spring (not shown,
but positioned between the recesses 62 and 56) will compress and
the hammer 38 will be retained in a rearward direction. As the
trigger is allowed to travel longitudinally forwardly (the finger
engagement portion 29 of the trigger), the disconnecter sear 70
will disconnect from the hammer disconnecter 72, and as shown in
FIG. 3, the hammer sear surface 46 will engage the trigger sear 36
to retain the hammer in a high-energy state until the trigger, more
specifically the finger engagement portion 29 of the trigger, is
pressed again.
[0018] As shown in FIG. 2, the disconnecter adjuster 80 is shown
where, referring ahead to FIG. 5, the disconnecter adjuster 80 is
configured to adjust the rotational distance between the
disconnecter 30 and the trigger 28. The disconnecter adjuster
receiving surface 82 of the trigger can receive the pressure from
the disconnecter adjuster wherein a preferred forwardly
disconnecter adjuster is a set screw and is accessible from the
vertical orientation when the hammer 38 is in a forward
location.
[0019] Referring back to FIG. 2, there is an initial position
adjuster 90 which, in one form, can be a set screw that is attached
to the trigger 28. This initial position adjuster adjusts the
initial position of the trigger with respect to the housing 22,
more specifically, the housing floor 23.
[0020] Referring now to FIG. 6, which is taken from line 6-6 of
FIG. 2, this shows another cross-sectional view of the trigger
module 20. As shown in FIG. 6, the safety adjuster 100 is shown. In
some embodiments, the safety 24 is a reversible adjustable selector
and safety adjuster 100 is a set screw. For example, set screw 100
may be operatively configured to engage the longitudinally rearward
region 60 of the trigger 28. In this way, the set screw can be used
to set the engagement of safety 24 to reduce the play between the
safety and the trigger. This adjustment helps counter a safety
selector hole positioned far enough on a lower receiver that it can
allow a firearm to fire on a safety condition. The safety can be
rotated by the safety lever 102 as shown in FIG. 6 as well as in
FIG. 4.
[0021] While the present invention is illustrated by description of
several embodiments and while the illustrative embodiments are
described in detail, it is not the intention of the applicants to
restrict or in any way limit the scope of the appended claims to
such detail. Additional advantages and modifications within the
scope of the appended claims will readily appear to those sufficed
in the art. The invention in its broader aspects is therefore not
limited to the specific details, representative apparatus and
methods, and illustrative examples shown and described.
Accordingly, departures may be made from such details without
departing from the spirit or scope of applicants' general
concept.
