Abstract
A trigger stop connector for semi-automatic firearms that have an enclosed striker assembly. Incorporated into firearms without major 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. The trigger stop connector, replacing a common connector, is designed with specific contact points to prevent overtravel of the trigger bar when operating in cooperation with the trigger of the firearm.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to firearms, and more particularly, to a firearm trigger stop mechanism.




2. Description of the Related Art




Firearms are mostly 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 quick firing and rapid succession. In addition to rapid firing, precision shooting is an aim that is strived for. 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 major structural changes to prevent a trigger from traveling any distance beyond the firing point to increase firing speed and target precision.




There are no similar trigger stop 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.




SUMMARY OF THE INVENTION




It is one of the main objects of the present invention to provide a trigger stop connector for firearms that is utilized to prevent a trigger from traveling beyond the point of firing.




It is another object of the present invention to incorporate a 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 trigger stop connector mechanism 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 trigger stop connector mechanism. Trigger stop 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, trigger stop connector


20


is manufactured as a single metallic piece and has a general consistent thickness throughout of approximately 0.10 mm to 2.00 mm, so as to cooperatively interact with the general trigger mechanism of semiautomatic firearms that have an enclosed striker assembly. Such a firearm may be “GLOCK”, without limitation to this specific brand.




As seen in

FIG. 1

, trigger stop connector


10


works in conjunction with trigger bar TB. While firearm F, shown in

FIG. 3

, is in the cocked position, 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.




Upon attaining the point of firing, firearm F, seen in

FIG. 3

, cycles, whereas spring force, not shown, assists trigger bar TB to shift. Guided by connector lip


28


and no longer biased against torso


21


, trigger bar TB slidably travels in a generally forward and upward direction until curved end


50


makes contact with connector lip


28


, whereas trigger bar TB then reattains the cocked position, thus completing the firing cycle.

Shown in

FIG. 2



a

24


′. Lip


24

22


′, shown in FIG.

. Connector leg


22


′ removably fits within firearm F to remain secured.




As best seen in

FIG. 3

, firearm F is in the cocked mode. 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. Stop leg


30


and stop lips


34


;


36


; and


38


are designed as specific contacts to prevent overtravel of trigger bar TB when operating in cooperation with trigger T of firearm F.




As best seen in

FIG. 4

, 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


, curved end


50


of trigger bar TB makes contact with stop lip


34


, and edge


52


makes contact with stop lip


36


and stop lip


38


. These contact points prevent 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, these contact points establish 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, as in FIG.
