Abstract

A self cleaning trigger stop connector & trigger connector for semi-automatic firearms that have an enclosed striker assembly. Incorporated into firearms without any structural changes, the trigger stop connector is designed to increase firing speed and prevent a fulcrum effect caused when a trigger mechanism travels a distance beyond the point of firing of the firearm, thus increasing target precision when discharging the firearm, a hole designed to self clean the trigger stop connector or trigger connector and trigger bar during operation, lessen the trigger pull weight and act as a reservoir for lubricants to increase reliability of the pistol. The single tab trigger stop connector, replacing a multiple leg or common non trigger stop connector, is designed with a specific contact point to prevent over travel of the trigger bar when operating in cooperation with the trigger of the firearm.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to firearms, and more particularly, to a self cleaning firearm single stop tab trigger control connector & trigger mechanism.
2. Description of the Related Art
Firearms are utilized by law enforcement, sport enthusiasts, and private owners for target and game. While participating in sport or especially during moments of self defense, it is desirable to initially discharge the firearm with minimal trigger travel distance to allow for accurate quick firing and rapid succession. In most semi-automatic firearms that have an enclosed striker assembly, the trigger mechanism travels a distance beyond the point of firing, increasing the time period for the initial and successive discharges. Additionally, the excess distance beyond the point of firing of the firearm causes a fulcrum effect. This fulcrum effect causes the barrel of the firearm to generally travel in a downward and sideward path, depending if the user utilizes their right or left hand to discharge the firearm. This generally downward and sideward path of the barrel after the initial discharge of the firearm, caused by the user exerting force beyond the point of firing, results in a reduction of accuracy and precision when firing.
In the past, firearm users have introduced epoxy or similar compounds immediately behind the trigger area, to fill in and prevent the trigger from surpassing the point of firing. However, this remedy is not precise and generally leaves an unfinished appearance to the firearm.
There is a need for a practical and inexpensive assembly that can be incorporated into firearms without any structural changes to prevent a trigger from traveling any distance beyond the firing point to increase target precision and firing speed.
There are no similar self cleaning single stop trigger control connectors or self cleaning trigger connector mechanisms to the best of applicant's knowledge that are built-in in the firearms to prevent excess travel of a trigger beyond the point of firing and that are self cleaning.

SUMMARY OF THE INVENTION

It is one of the main objects of the present invention to provide an improved trigger stop connector utilizing one stop tab to control trigger travel for firearms that is self cleaning and utilized to prevent a trigger from traveling beyond the point of firing.
It is another object of the present invention to incorporate a self cleaning trigger stop connector for firearms to prevent over manipulation of the trigger which causes a reduction of accuracy while repetitive firing.
It is yet another object of this invention to increase the speed of firing a firearm with a reduced trigger travel distance.
It is still another object of the present invention to provide a self cleaning trigger stop connector mechanism utilized with semi-automatic pistols that have an enclosed striker assembly.
It is still another object of the present invention to provide a self cleaning trigger stop connector mechanism that due to the hole will lessen the friction of the moving parts by reducing the contact surfaces of the biased moving parts thus lightening the trigger pull force required to fire the pistol utilized with semi-automatic pistols that have an enclosed striker assembly.
It is still another object of the present invention to provide a self cleaning trigger stop connector mechanism that due to the hole will create a reservoir for lubricants thus increasing the reliability of the moving parts by reducing the mechanical friction of the contact surfaces of the biased moving parts utilized with semi-automatic pistols that have an enclosed striker assembly.
It is yet another object of this invention to provide such a device that is inexpensive to manufacture and maintain while retaining its effectiveness.
Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to the drawings, where the present invention is generally referred to with numeral 10, it can be observed that it basically includes trigger stop connector 20, bent at predetermined locations to permit its mechanical transactions to effectuate a single stop tab trigger control connector mechanism. Single stop tab trigger control connector 20 is made out of a durable and light weight material as stainless steel, alloy metal, or other material having similar characteristics. In the preferred embodiment, single stop tab trigger control connector 20 is manufactured as a single metallic piece and has a general consistent thickness throughout of approximately 0.65 mm to 1.25 mm, so as to cooperatively interact with the general trigger mechanism of semiautomatic firearms that have an enclosed striker assembly. The hole or opening, referred further as the hole is placed so as to cooperatively interact with the trigger bar mechanism of semiautomatic firearms that have an enclosed striker assembly and cause the removal of debris as the trigger bar operates. Such a firearm may be “GLOCK”, without limitation to this specific brand.
As seen in FIG. 1, single stop tab trigger control connector 10 works in conjunction with trigger bar TB. While firearm F, shown in FIG. 3, trigger bar TB is biased against torso 21. As trigger T is pulled, trigger bar TB slidably travels in a generally rearward and downward direction over the self cleaning hole 40 removing debris. Connector lip 24 serves to guide curved end 50 trigger bar TB remains biased against torso 21 at the point of firing. At the point of firing, leg 30 is contacted to prevent further travel of trigger bar TB.
Upon attaining the point of firing, firearm F, seen in FIG. 3, cycles, whereas spring force, not shown, assists trigger bar TB to shift. The connector guided by connector lip 28 attached by connector leg 26 and a cam on the slide not shown causes the connector to violently shift inward which also assists the hole 40 in cleaning the contact surfaces by throwing debris free from the mechanism no longer biased against torso 21, trigger bar TB slidably travels in a generally forward and upward direction until curved end 50 makes contacts again with connector lip 24, whereas trigger bar TB is again biased against torso 21 where it then re-attains the cocked position, thus completing the firing cycle. Opposite in direction from connector lips 24; 28; is connector leg 22. Connector leg 22 re-movably fits within firearm F, shown in FIG. 3, to secure instant invention 10.
Seen in FIG. 1 a is present invention 10 in a preferred embodiment. The following dimensions of present invention 10 describe an example of the preferred embodiment. As seen, torso 21 has lip 24 extending a distance approximately between 0.25 mm to 2.00 mm. Lip 24 serves to contain trigger bar TB when biased against it. Connector leg 26 extends from torso 21 at a predetermined angle a distance approximately 1.00 to 3.00 mm and has connector lip 28 extending a distance of approximately 0.25 mm to 2.00 mm. Extending approximately 90 degrees from connector leg 26 is stop leg 30. Stop leg 30 extends approximately perpendicularly 1.00 mm to 5.00 mm from connector leg 26 and is approximately 1.00 to 3.00 mm in width.
Seen in FIG. 1 b is a non trigger stop connector with the self cleaning hole 40 shown made into a connector.
Opposite in direction from connector lips 24; 28; is connector leg 22, shown in FIG. 1. Connector leg 22 not shown in FIG. 1 b, re-movably fits within firearm F, shown in FIG. 3, to secure non trigger stop connector.
Seen in FIG. 1 c is a non trigger stop connector with an alternate embodiment of the self cleaning hole 41 shown made into a connector. Opposite in direction from connector lips 24; 28; is connector leg 22 not shown in FIG. 1 c, shown in FIG. 1. Connector leg 22 re-movably fits within firearm F, shown in FIG. 3, to secure non trigger stop connector.
As seen in FIG. 2, is prior art trigger stop connector 20′ works in conjunction with trigger bar TB. While firearm F, shown in FIG. 3, trigger bar TB is biased against torso 21′. As trigger T is pulled, trigger bar TB slidably travels in a generally rearward and downward direction. Connector lip 24′ serves to guide curved end 50. Trigger bar TB remains biased against torso 21′ at the point of firing. At the point of firing, certain points of contact are made to prevent further travel of trigger bar TB. Curved end 50 of trigger bar TB makes contact with stop lip 34′, stop leg 30′ makes contact with cross edge 60, and edge 52 of trigger bar TB simultaneously makes contact with stop lip 38′ and stop lip 36′ to prevent further travel of trigger T fixedly secured to trigger bar TB.
Seen in FIG. 2 a is prior art trigger connector 20′. Prior art connector 20′ works in conjunction with trigger bar TB. While firearm F, shown in FIG. 3, trigger bar TB is biased against torso 21′. As trigger T is pulled, trigger bar TB slidably travels in a generally rearward and downward direction. Connector lip 24′ serves to guide curved end 50. Trigger bar TB remains biased against torso 21′ at the point of firing. After the point of firing, trigger bar TB continues to travel generally in a rearward and downward direction until a spring force, not shown, causes trigger bar TB to shift. Guided by connector lip 28′, edge 52 of trigger bar TB slidably travels in a generally forward and upward direction until completing the firing cycle. Shown in FIG. 2 a is prior art connector 20′. Torso 21′ has lip 24′. Lip 24′ serves to contain trigger bar TB when biased against it. Connector leg 26′ extends from torso 21′ at a predetermined angle and has connector lip 28′. Opposite in direction from connector lips 24′ and 28′ is connector leg 22′, not shown connector leg 22′ re-movably fits within firearm F to remain secured.
As best seen in FIG. 3, once the user grasps firearm F, aims, and is ready to fire, the user exerts a force to overcome the force of trigger T. Trigger T is mechanically connected to trigger bar TB. Upon depressing trigger T, trigger bar TB is guided and thereby moves in a generally rearward and downward path over the self cleaning hole removing debris. Stop leg 30 is designed as specific contact to prevent over travel of trigger bar TB when operating in cooperation with trigger T of firearm F.
As best seen in FIG. 3, firearm F is in the fired mode. At this moment, the user has pulled trigger T with sufficient force and a sufficient distance to activate the firing pin mechanism, not shown, which in turn makes contact with the primer of a bullet, not shown, discharging firearm F. At the moment of discharge, stop leg 30 contacts cross edge 60, cross edge 60 would be in contact with stop leg 30 for illustration a small gap was inserted for a better perspective of stop leg 30 & cross edge 60. This contact point prevents over manipulation of trigger T past the point of firing. Thus, the ability to prevent movement of firearm F is increased because the fulcrum effect is greatly reduced. The excess distance beyond the point of firing of firearm F is what causes the fulcrum effect. The fulcrum effect causes the barrel of firearm F to generally travel in a downward and sideward path. Additionally, this contact point establishes a shortened trigger travel distance. With a shortened trigger travel distance, less time is required for the user to discharge firearm F. As a result, the user benefits from each subsequent discharge with less time required for firearm F to cycle back into the cocked mode not shown.
The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
