On referring to the drawings in detail and, in particular to FIG. 1, a trigger assist mechanism of this invention, indicated generally at 10, is shown as attached to a conventional trigger assembly 12 as found on a firearm or weapon apparatus including pistols, shotguns, rifles, and early manufactured weapons in which a trigger assembly is used to operate a firing mechanism to explode and release a bullet member from a firearm barrel in a conventional manner.

The purpose of the trigger assist mechanism 10 is to provide a means of actuating a conventional or existing trigger member 14 which is surrounded by a trigger guard assembly 16.

The existing trigger member 14 is provided with a curved trigger section 18 having a trigger pivot hole to receive a trigger pivot pin 22 therein.

The trigger guard assembly 16 includes an oval guard member 26 having a central trigger opening 30 enclosing the curved trigger section 18 therein to prevent accidental movement of the existing trigger member 14.

The oval guard member 26 having an anchor section 31 which has an anchor hole 28 therein operable to receive a screw member to be attached to a portion of the firearm or weapon apparatus in a conventional manner.

As noted in FIG. 5, the trigger assist mechanism 10 includes 1) a main connector anchor block assembly 32 providing means for connecting to the conventional trigger assembly 12; and 2) a trigger assist assembly 34 which is connected to the main connector anchor block assembly 32 in a manner to be explained.

The main connector anchor block assembly 32 includes a U-shaped anchor block member 36 having an outer support leg section 38 interconnected a central support member 40.

The outer support leg section 38 includes a first leg section 42 parallel to a spaced second leg section 44.

The first leg section 42 is provided at an upper end thereof with a trigger pivot pin hole 46 aligned with a similar hole in the second leg section 44 as will be noted.

The second leg section 44 is provided with 1) an upper trigger pivot pin hole 46 aligned with the trigger pivot pin hole 46 in the first leg section 42; and 2) a pair of spaced internally threaded anchor holes 50 for reasons to be noted.

The trigger assist assembly 34 includes 1) a main trigger lever member 54 pivotally connected to the outer support leg section 38; and 2) a trigger and roller support assembly 56 connected to the main trigger lever member 54 and the anchor block member 36 as will be noted.

The main trigger lever member 54 includes a curved trigger member 58 resembling the existing trigger member 14 except mounted in an adjacent upside down relationship as noted in FIG. 2.

The curved trigger member 58, as noted in FIG. 5, includes an actuator section 60 integral with a pivot connector section 62. The actuator 60 is of arcuate shape and operable to receive a person's trigger firing forefinger there against as will be described.

The pivot connector section 62 is provided with 1) a pair of aligned roller shaft openings 64; 2) a roller actuator slot or cut-out 65; and 3) a pair of aligned trigger support openings 66 for reasons to be noted.

As best noted in FIG. 5, the trigger and roller support assembly 56 includes 1) a trigger pivot member 68; 2) connector block anchor members 70; and 3) a roller assembly 78.

The trigger pivot member 68 is a pivot pin 74 adapted to be placed through the aligned trigger pivot pin holes 46 in the first leg section 42 and the second leg section 44.

The connector block anchor members 70 are conventional Allen screws, each having an Allen head member 76 with a body member 78.

Each body member 78 is provided with external threads 80; an outer pointed anchor section 82; and an Allen wrench opening 84.

The pointed anchor section 82 is operable to engage and secure the entire main connector anchor block assembly 32 to the outer oval guard member 26 of the trigger guard assembly 16 as noted in FIG. 4.

Each Allen wrench opening 84 is of a conventional six-sided shape so as to receive a head of a conventional Allen wrench therein for ease of rotation of the Allen head members 76 for connecting and releasing purposes in a conventional manner.

The roller assembly 72 includes a roller member 86 rotatably mounted on a roller support shaft member 88 and positioned in the roller actuator slot or cut-out 65.

The roller member 86 has an outer contact surface 90 engageable with an adjacent portion of the existing trigger member 14 and, more specifically, a lower portion of the curved trigger section 18.

The roller member 86 is also provided with a central anchor hole 92 to receive the roller support shaft member 88 which allows rotation of the roller member 86 thereon.

It is obvious that the trigger assist mechanism 10 of this invention can be constructed of numerous metal materials or can be of a high strength plastic composition.

USE AND OPERATION OF THE INVENTION

In the use and operation of this invention, the trigger assist mechanism 10 is operable to be securely anchored adjacent a conventional trigger assembly as found on a firearm or weapon apparatus such as a pistol, shotgun, rifle, early manufactured weapons, or the like.

The main connector anchor block assembly 32 is operable to place the outer support leg section 38, namely, the first leg section 42 and the second leg section 44 about the trigger guard assembly 16 of the conventional trigger assembly 12 as noted in FIGS. 1, 2, and 4.

The U-shaped anchor block member 36 is thereupon adjusted vertically and laterally so as to place the central support member 40 in abutting relationship with the anchor section 31 of the oval guard member 26 of the conventional trigger assembly 12.

Next, a conventional Allen wrench member can be utilized with the respective Allen head members 76 mounted within the spaced respective threaded anchor holes 50 so as to place the external threads 80 of the Allen head member 76 into locking engagement with internal threads within the spaced threaded anchor holes 50.

The Allen wrench member can then be utilized in a conventional manner with a head portion thereof placed in the respective Allen wrench openings 84 and rotated in a clockwise direction to achieve engagement of the outer pointed anchor sections 82 with an outer surface of the oval guard member 26 as best noted in FIG. 4.

At this time, the main connector anchor block assembly 32 is adjustable laterally so as to place the main trigger lever member 54 in an abutting and adjacent relationship with the existing trigger member 14 and, more specifically, the curved trigger section 18 as clearly shown in FIG. 2.

After the above adjustment has been made, the trigger assist mechanism 10 of this invention is operable to be utilized to cause a pivotal movement of the existing trigger member 14 by the main trigger lever member 54 of this invention.

As noted in FIG. 6, a person's forefinger on a trigger actuator hand is normally utilized as a “trigger finger” and is squeezed rearwardly as shown by an arrow 96 in FIG. 6. This squeezing or slightly rearward movement of a trigger finger on a person actuating the conventional trigger assembly 12 operates through contact with the roller member 86 and, specifically, an outer contact surface 90 against a lower portion of the curved trigger section 18 on the existing trigger member 14. This acts through a leverage function so that less pressure is required against the main trigger lever member 54 and its curved trigger member 58 to force rearward pivotal movement of the existing trigger member 14. The existing trigger member 14 pivots about the trigger pivot pin 22 to cause a firing action within a firing mechanism in a conventional manner in the firearm or weapon apparatus.

The purpose and function of the trigger assist mechanism 10 of this invention is to require less pressure to be applied to the main trigger lever member 54 which, in turn, through the roller member 86 operates to move the existing trigger member 14 without any jerking type motion on operation of the trigger assist mechanism 10.

It has been found the trigger assist mechanism 10, as designed and illustrated herein, is operable with a large percentage of existing or conventional trigger assemblies 12 as found on existing firearm and weapon apparatus including the aforementioned pistols, shotguns, rifles, early manufactured weapons, and the like.

The trigger assist mechanism 10 is sturdy in construction; adjustable and reliable in repeat trigger firing operations to cause the operation of a trigger pull function on firing a firearm or weapon apparatus; and substantially maintenance free.

While the invention has been described in conjunction with a preferred specific embodiment thereof, it will be understood that this description is intended to illustrate and not to limit the scope of the invention, which is defined by the following claims:
