A long need has existed to provide a trigger mechanism that provides a practice firearm with a trigger feel that is more natural and realistic to the user, including more realistic feedback and trigger action, as well as the ability to more accurately mimic the unique feel of specific firearm models. Practice pistols, or practice firearms in general, are engineered to function like a live, real firearm, and may be used in a variety of contexts such as those who want to train in a simulated combat environment, or prefer to avoid visiting a live fire gun range, for example. By allowing a user to fire a more realistic practice firearm, such as a practice pistol, training and reality based shooting exercises result in increased efficacy and greater improvement by a user when handling a live fire firearm, as well as when engaged in a real world combat environment. Similarly, an improved and more realistic trigger mechanism for practice firearms would provide a more realistic, effective, and enjoyable experience for a user as part of a larger shooting simulator exercise, such as a laser based shooting simulator, or a shot scoring module (SSM) shooting simulator. These advantageous attributes in a practice firearm, such as realistic trigger pull and feel, are desired by and sought after by those who use firearms recreationally, as well as by those in professional law enforcement and military. Thus, there exists a need in the art for an effective and novel trigger mechanism that provides a realistic and accurate experience for the user of a firearm, including a practice pistol.

All references, publications, and patents cited herein are incorporated by reference in their entirety as though they are fully set forth. Unless defined otherwise, technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Advanced Gunsmithing: A Manual of Instruction in the Manufacture, Alteration, and Repair of Firearms (75th Anniversary Edition—Feb. 17, 2015), W. F. Vickery provide one skilled in the art with a general guide to many of the terms used in the present application. One skilled in the art will recognize many methods and materials similar or equivalent to those described herein, which could be used in the practice of the present invention. Indeed, the present invention is in no way limited to the methods and materials described.
As used herein, the term “modular trigger mechanism,” also includes apparatuses that may be referred to as a “trigger mechanism.”
As used herein, the abbreviation “SSM” refers to shot-scoring module, and/or self-scoring module.
As used herein, the term “static sear” refers to a sear component of a trigger mechanism that is a non-movable component and does not rotate.
As used herein, the terms “firearm,” and “gun,” are used interchangeably.
As used herein, the term “practice pistol,” refers to an apparatus intended and designed to mimic or replicate or simulate a live action pistol or firearm, including but not limited to a center fire pistol or rifle. Similarly, the term “practice firearm,” refers to an apparatus intended to be used to mimic or replicate or simulate a live action firearm.
As used herein, “specific live firearm model” refers to a live action firearm that is of the model that a practice firearm is intended to mimic or replicate.
As further disclosed herein, modular trigger mechanisms in accordance with various embodiments herein have been designed so that they may improve user feel and trigger action for practice firearms. For example, a practice firearm may be designed so that it has the capability to mimic for a user various center fire pistols, including many of those live action firearms currently commercially available, such as a Glock 17, Sig P320, or 1911, for example. In accordance with various embodiments herein, trigger mechanisms may be designed with the capability to perform and give the user a sense of a center fire pistol trigger. In another embodiment, trigger mechanisms may be designed with the capability to perform and give the user a sense of a center fire pistol trigger in that its positional geometry, weight of pull, weight at break, and trigger position at disconnect reset point, for example, will perform within a realistic range. In another embodiment, the realistic range is a range that serves to mimic for the user a type of center fire pistol. In another embodiment, the apparatus interacts with electronics within a practice pistol to provide feedback and/or data to the user. In another embodiment, the apparatus interacts with a practice pistol to provide a shot scoring system.
Turning to
In one embodiment, the present invention provides an apparatus comprising a static sear 110 and a first moving part and/or a second moving part. In another embodiment, the first moving part is a trigger 106. In another embodiment, the second moving part is a sear bar 103. In another embodiment, the static sear 110 can be rotated within a range to alter break weight at the trigger 106, but is static during firing sequences. In accordance with various embodiments herein, the apparatus provides a modular design that allows various present characteristics to be interchangeable to the frame. In another embodiment, the apparatus interacts with a circuit board. In another embodiment, the apparatus interacts with a circuit board by one or two tactile switches to achieve various electronic effects.
Unlike trigger mechanisms used for alternative, otherwise commercially available firearms or practice pistols, embodiments herein incorporate a static sear 110 component. The static sear 110 provides for no rotation of the sear, which enables a trigger mechanism with fewer moving parts. A trigger mechanism with fewer moving parts provides various advantages in the art, such as cost advantage, greater dependability, and modularity. Additionally, in accordance with various embodiments herein, use of a static sear 110, sear bar 103, and torsion spring 109, and combinations thereof, as components of a trigger mechanism in conjunction with a practice pistol, provide a more realistic and accurate experience for a user when firing a practice pistol, compared to alternative, otherwise commercially available practice pistols with corresponding trigger mechanisms.
Similarly, as known to those of skill in the art, each model of firearm can have a unique and specific feel to the user when firing that model of firearm. Thus, in accordance with various embodiments herein, use of a static sear 110, sear bar 103, and torsion spring 109, and combinations thereof, enable greater tunability of feedback for the user of a practice pistol, or practice firearm, relative to alternative, commercially available practice pistols and trigger mechanisms, thus allowing the ability of a user to experience a feel when firing the practice pistol that accurately and reliably mimics specific firearm models as desired by the user.
Other alternative practice pistols in the prior art rely on a traditional trigger design, and may then attempt to influence its characteristics by use of an electromagnet. In contrast, various embodiments herein provide a trigger mechanism that incorporates a non-traditional, static sear for its trigger design. Similarly, rather than attempting to influence its characteristics through use of an electromagnet, various embodiments herein influence its characteristics mechanically and/or by trigger weight. In one embodiment, the present invention provides a trigger mechanism comprising a static sear 110, wherein friction, or break weight, at opposing junctions is influenced by the angle of a static sear ramp 102, and the force of a torsion spring 109 baring downward on a sear bar 103 as its force against the static sear 110 by a trigger 106, so that when sufficient force is applied by the user to the trigger 106 to overcome the resistance, or friction, the sear bar 103 advances abruptly to give the user the impression of a traditional sear mechanism. In another embodiment, the trigger mechanism includes an electromechanical aspect that provides tactile feedback to the user with no imparted influence to the trigger break.
In one embodiment, the practice pistol is part of a general practice shooting package, and components thereof. In one embodiment, the trigger mechanism is adapted for use in a practice pistol that interfaces with a laser-based interface, as part of a larger, general practice shooting package, and various components thereof. In another embodiment, the trigger mechanism is adapted for use in a practice pistol that interfaces with a shot-scoring module (SSM), as part of a larger, general practice shooting package, and various components thereof. In another embodiment, the trigger mechanism is adapted for use in a practice pistol that is wireless.
Further, as readily apparent to one of skill in the art, a trigger mechanism may serve as an apparatus that is to be used as a part of, or component of, a firearm, such as a center fire pistol or a rifle. Or, for example, in accordance with various embodiments herein, the trigger mechanism may also serve as an apparatus that is part of, or component of, a practice firearm. Thus, as apparent to one of skill in the art, the application is in no way limited to only modular trigger mechanisms to be used for practice pistols, and may instead also be used as a trigger mechanism that is a part of an active, real firearm. Similarly, the application is in no way limited for use in only firearms that are center fire pistols, and may include and be adapted for use in other types of firearms, such as rifles. Similarly, the application is in no way limited to only practice pistols modeled after center fire pistols, and may also be used as part of a practice firearm modeled after other types of firearms, such as rifles. Or, as readily apparent to one of skill in the art, the firearms are in no way limited to only the specific models explicitly stated herein. For example, various embodiments herein may be used for, or modeled after, any number of 9 mm handgun firearms, including but not limited to: Glock 19, Browning Hi Power, CZ 75B, Smith & Wesson Shield, Springfield XD(M) Competition Series, Sig Sauer P226, Walther P99 AS, Beretta 92FS, Heckler and Koch VP9, and Ruger SR9. Or, for example, various embodiments herein may be used for, or modeled after, any number of assault rifle firearms including but not limited to: Mossberg MMR Pro. Mossberg MMR ProMossberg, JP Rifles SRC-11, JP Rifles SRC-11JP, Savage Arms MSR 10 Long Range, DPMS Prairie Panther, Daniel Defense Ambush 300 Kryptek Highlander, Wilson Combat Ultralight Hunter, DPMS GII Hunter, and Ruger AR-556 450 Bushmaster Model 8522.
