DETAILED DESCRIPTION

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.

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.

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.

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.

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.

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.

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.

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.

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.
