Patent Application
20250164204
Described herein are trigger systems for weapons, such as Glock-style pistols and AR-15 rifles. The trigger systems improve existing trigger systems because they reliably fire every time but never “skip” (i.e., misfire or fire continuously like an automatic weapon) as a result of trigger fluttering or other issues. The trigger systems make the guns safer to use and prevents gun owners from facing liability for carrying or using an automatic weapon, which is illegal for most citizens in the United States and in other countries.
Examples of existing trigger systems for a Glock can be found in U.S. Pat. No. 9,316,455, incorporated by reference herein. Examples of existing AR-15 triggers can be found for example in U.S. Pat. No. 11,796,270, incorporated by reference herein.
The trigger systems described below improve existing trigger systems because they reliably fire every time but never “skip” (i.e., misfire or fire continuously like an automatic weapon) as a result of trigger fluttering or other issues. The components are sized and positioned such that “fluttering” of the trigger does not matter—after firing, the weapon will not be ready to fire again unless the user releases the trigger. Furthermore, the system described herein feels better and is more reliable than a standard Glock trigger system, which uses flimsy components to catch and pull back the firing pin. The trigger systems described below have a “dual-adjustment” capability—a user can adjust both the trigger pull force and the tightness of the firing sear to desired settings, which is very useful in competition and other settings.
Objects and advantages pertaining to the trigger may become apparent upon referring to the example embodiments illustrated in the drawings and disclosed in the following written description or appended claims.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
Aspects and applications of the invention presented here are described below in the drawings and detailed description of the invention. Unless specifically noted, it is intended that the words and phrases in the specification and the claims be given their plain, ordinary, and accustomed meaning to those of ordinary skill in the applicable arts. The inventors are fully aware that they can be their own lexicographers if desired. The inventors expressly elect, as their own lexicographers, to use only the plain and ordinary meaning of terms in the specification and claims unless they clearly state otherwise and then further, expressly set forth the “special” definition of that term and explain how it differs from the plain and ordinary meaning. Absent such clear statements of intent to apply a “special” definition, it is the inventors' intent and desire that the simple, plain and ordinary meaning to the terms be applied to the interpretation of the specification and claims.
The inventors are also aware of the normal precepts of English grammar. Thus, if a noun, term, or phrase is intended to be further characterized, specified, or narrowed in some way, then such noun, term, or phrase will expressly include additional adjectives, descriptive terms, or other modifiers in accordance with the normal precepts of English grammar. Absent the use of such adjectives, descriptive terms, or modifiers, it is the intent that such nouns, terms, or phrases be given their plain, and ordinary English meaning to those skilled in the applicable arts as set forth above.
Further, the inventors are fully informed of the standards and application of the special provisions of 35 U.S.C. § 112, ¶6. Thus, the use of the words “function,” “means” or “step” in the Detailed Description or Description of the Drawings or claims is not intended to somehow indicate a desire to invoke the special provisions of 35 U.S.C. § 112, ¶6, to define the invention. To the contrary, if the provisions of 35 U.S.C. § 112, ¶6 are sought to be invoked to define the inventions, the claims will specifically and expressly state the exact phrases “means for” or “step for and will also recite the word “function” (i.e., will state “means for performing the function of [insert function]”), without also reciting in such phrases any structure, material or act in support of the function. Thus, even when the claims recite a “means for performing the function of . . . ” or “step for performing the function of . . . ,” if the claims also recite any structure, material or acts in support of that means or step, or that perform the recited function, then it is the clear intention of the inventors not to invoke the provisions of 35 U.S.C. § 112, ¶6. Moreover, even if the provisions of 35 U.S.C. § 112, ¶6 are invoked to define the claimed inventions, it is intended that the inventions not be limited only to the specific structure, material or acts that are described in the preferred embodiments, but in addition, include any and all structures, materials or acts that perform the claimed function as described in alternative embodiments or forms of the invention, or that are well known present or later-developed, equivalent structures, material or acts for performing the claimed function.
A more complete understanding of the present invention may be derived by referring to the detailed description when considered in connection with the drawing figures wherein:
Elements and acts in the figures are illustrated for simplicity and have not necessarily been rendered according to any particular sequence or embodiment.
Embodiments depicted are shown only schematically, and not all features may be shown in full detail or in proper proportion. Certain features or structures may be exaggerated relative to others for clarity. The embodiments shown are examples only, and should not be construed as limiting the scope of the present disclosure or appended claims.
In the following description, and for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the various aspects of the invention. It will be understood, however, by those skilled in the relevant arts, that the present invention may be practiced without these specific details. In other instances, known structures and devices are shown or discussed more generally in order to avoid obscuring the invention. In many cases, a description of the operation is sufficient to enable one to implement the various forms of the invention, particularly when the operation is to be implemented in software. It should be noted that there are many different and alternative configurations, devices and technologies to which the disclosed inventions may be applied. The full scope of the invention is not limited to the examples that are described below.
As shown in
After the weapon is fired, the slider of the weapon, including the firing pin 14, recoils back, as is known in the art. See, e.g., https://www.youtube.com/watch?v=V2RDitgCaDO (YouTube video titled “How a Glock works” by Matt Rittman, dated Jul. 2, 2019).
The components are sized and positioned such that “fluttering” of the trigger does not matter—after firing, the weapon will not be ready to fire again (i.e., in the start position of
Furthermore, the system shown in
When the weapon is fired the bolt carrier returns the hammer 52 to its cocked position. See, e.g., https://www.youtube.com/watch?v=omv85cLfmxU (YouTube video titled “How an AR-15 Works” by Matt Rittman, dated Aug. 10, 2022).
At that time, if the user is still holding the trigger shoe 50 in the position that was used to fire the gun, protrusion 64 of disconnector 62 will engage with protrusion 56 of hammer 52, thereby preventing the hammer from firing while the trigger shoe 50 is still pulled back from firing the prior round of ammunition. In this way, the trigger system cannot be used as an automatic weapon.
When the user releases the trigger shoe 50, the protrusion 64 of disconnector 62 will disengage from protrusion 56 of hammer 52, but at the same time, the protrusion 60 of firing sear 58 engages with the protrusion 54 of hammer 52 to prevent the weapon from firing. The system will then be back in the position shown in
The components are sized and positions such that “fluttering” of the trigger does not matter—after firing, the weapon will not be ready to fire again (i.e., in the start position of
Furthermore, the system shown in
In addition, the system shown in
The trigger system can also have a system for adjusting the trigger pull force that is required to fire the weapon, as disclosed in U.S. Pat. No. 11,796,270. That system for adjusting the trigger pull force, including the adjustable screw, is shown in
The trigger system thus has a “dual-adjustment” capability—a user can adjust both the trigger pull force and the tightness of the firing sear to desired settings, which is very useful in competition and other settings.
The Figures show only certain portions of the weapon that are necessary for illustrating the described system, and the full weapon is not depicted.
In the foregoing Detailed Description, various features can be grouped together in several example embodiments for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that any embodiment requires more features than are expressly recited in the corresponding claim. Rather, inventive subject matter may lie in less than all features of a single disclosed example embodiment. Thus, the present disclosure shall also be construed as implicitly disclosing any embodiment having any suitable set of one or more disclosed or claimed features (i.e., a set of features that are neither incompatible nor mutually exclusive) that appear in the present disclosure, including those sets that may not be explicitly disclosed herein.
The scope of the originally filed claims does not necessarily encompass the whole of the subject matter disclosed herein. The originally filed claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separate disclosed embodiment. The scope of subject matter encompassed by each claim shall be determined by the recitation of only that claim.
The conjunction “or” is to be construed inclusively (e.g., “a dog or a cat” would be interpreted as “a dog, or a cat, or both”; e.g., “a dog, a cat, or a mouse” would be interpreted as “a dog, or a cat, or a mouse, or any two, or all three”), unless: (i) it is explicitly stated otherwise, e.g., by use of “either . . . or,” “only one of,” or similar language; or (ii) two or more of the listed alternatives are mutually exclusive within the particular context, in which case “or” would encompass only those combinations involving non-mutually-exclusive alternatives. The words “comprising,” “including,” “having,” and variants thereof, wherever they appear, shall be construed as open ended terminology, with the same meaning as if the phrase “at least” were appended after each instance thereof.
If any one or more disclosures are incorporated herein by reference and such incorporated disclosures conflict in part or whole with, or differ in scope from, the present disclosure, then to the extent of conflict, broader disclosure, or broader definition of terms, the present disclosure controls. If such incorporated disclosures conflict in part or whole with one another, then to the extent of conflict, the later-dated disclosure controls.
