Abstract

Various solutions to aide in the one-handed usage of certain types of firearms, such as pistols/handguns, are described. Each solution is a type of stabilizer that aids in stabilization of a large pistol, such as an AR pattern pistol, against the forearm of the user. By adding an additional point of contact for the firearm, greater stability is achieved, thus allowing for safer and more accurate operation of the firearm. Various implementations in accordance with the present disclosure allow for easy ambidextrous use without sacrificing stability.

Description

CROSS REFERENCE TO RELATED PATENT APPLICATION(S)

The present disclosure claims the priority benefit of U.S. Provisional Patent Application No. 62/550,413, filed on 25 Aug. 2017, the content of which is herein incorporated by reference in its entirety.

TECHNICAL FIELD

The present disclosure is generally related to firearms and, more particularly, to ambidextrous stabilization for firearms.

BACKGROUND

Unless otherwise indicated herein, approaches described in this section are not prior art to the claims listed below and are not admitted as prior art by inclusion in this section.
By definition, a pistol or handgun is a firearm designed such that a user should be able to fire the pistol or handgun from one hand instead of both hands of the user. A large pistol or handgun, such as an AR pistol, can be unwieldy due to its heavy weight and large size. The point of balance on such firearms tend to be forward biased, causing ergonomic difficulties and instability.
Existing pistol braces are generally secured to the forearm of the user via a strap, a sling or pressure. However, it is disadvantageous to use such stabilizing mechanisms due to inflexibility. Additionally, strap- or sling-type systems tend to be difficult to reposition or adjust once secured to the forearm of the user. Moreover, pressure-based systems usually do not adequately secure the firearm to the forearm of the user.

SUMMARY

The following summary is illustrative only and is not intended to be limiting in any way. That is, the following summary is provided to introduce concepts, highlights, benefits and advantages of the novel and non-obvious techniques described herein. Select implementations are further described below in the detailed description.

DETAILED DESCRIPTION OF PREFERRED IMPLEMENTATIONS

Detailed embodiments and implementations of the claimed subject matters are disclosed herein. However, it shall be understood that the disclosed embodiments and implementations are merely illustrative of the claimed subject matters which may be embodied in various forms. The present disclosure may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments and implementations set forth herein. Rather, these exemplary embodiments and implementations are provided so that description of the present disclosure is thorough and complete and will fully convey the scope of the present disclosure to those skilled in the art. In the description below, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations.

Overview

In various implementations, a stabilizer in accordance with the present disclosure may secure a firearm to a forearm of a user (whether the right forearm or the left forearm) via a hook-and-loop attachment system that provides security in retention, while maintaining flexibility and ambidexterity. At times, it may be advantageous to switch the stabilizer from the user's dominant hand to the user's non-dominant hand to fire, and such ambidexterity is usually precluded by conventional strap-type systems.
In various implementations in accordance with the present disclosure, the user may wear a cuff that has one half of a hook-and-loop attachment system or another type of attachment system, and a stabilizer in accordance with the present disclosure may be covered by a corresponding other half of the attachment system. In some implementations, the stabilizer may be used with the attachment system. Alternatively, the stabilizer may be used without the attachment system.
In some implementations, a contact surface of the stabilizer which comes in contact with the forearm of the user when in use may be curved. In some implementations, the stabilizer may include two curved surfaces—a right contact surface on the right side thereof and a left contact surface on the left side thereof as seen from a perspective of the user. As such, regardless with which arm of the user the stabilizer is used, the curvature of either contact surface on the side of the stabilizer in contact with the user can accommodate the forearm of the user. In some implementations, the contact surface may include a frictional interface disposed thereon so that no arm attachment is necessary. The frictional interface may include, for example and without limitation, any kind of non-slip, non-permanent adhesive material. With the frictional interface, no arm attachment would be necessary as the frictional interface provides friction between the stabilizer and the forearm (or whatever is worn on the forearm) of the user.
In some implementations, a strong, impact resistant polymer may be the material used to make the stabilizer. Alternatively, any rigid or semi-rigid material may be used for the stabilizer. Some example materials may include, for example and without limitation, inflexible rubber, metal or metal alloy, and thermoplastics.
A stabilizer in accordance with the present disclosure may be affixed to the firearm in one of several ways. For instance, with an AR pistol, the stabilizer may be affixed to the receiver extension of the AR pistol via one or more tensioning screws. If the receiver extension has an integral accessory rail such as a Picatinny type rail, the stabilizer may be attached to the firearm via the accessory rail.
It is noteworthy that the overall shape and the method of mounting/affixing the stabilizer may be changed without altering the intention of the present disclosure. Moreover, the material(s) used for the stabilizer should be rigid and strong enough to withstand normal use of a firearm part.
Buffer Tube with Picatinny Rail
FIG. 1A-FIG. 1D illustrate various views of a buffer tube 110 in accordance with an implementation of the present disclosure. Description of buffer tube 110 below is provided with reference to FIG. 1A-FIG. 1D.
In some implementations, buffer tube 110 may include a tubular portion and an attachment portion. The tubular portion may be generally cylindrical in shape. The tubular portion may include a first distal end (e.g., front end) and a second distal end (e.g., rear end) opposite the first distal end. The first distal end may be configured to be mechanically received in a firearm (e.g., an AR-type pistol). The attachment portion may extend from a portion of an exterior surface of the tubular portion between the first distal end and the second distal end. In some implementations, the attachment portion may include a plurality of protrusions or serrations configured to accommodatingly mate with a MIL-STD-1913 rail, a Standardization Agreement 2324 rail, a Picatinny rail, a Weaver rail, a STANAG 4694 rail, a NATO accessory rail, an accessory mounting rail, or a combination thereof.
In some implementations, the first distal end may be threaded and configured to be screwed into a receiver of an AR-type firearm.
In some implementations, the tubular portion may include a hollow tube having a hole open at the first distal end and closed off at the second distal end.
In some implementations, the tubular portion may also include one or more grooves on an exterior surface of the tubular portion and extending along a longitudinal direction of the tubular portion.

FIG. 2A-FIG. 2E illustrate various views of an ambidextrous stabilizer 220 in accordance with an implementation of the present disclosure. Description of ambidextrous stabilizer 220 below is provided with reference to FIG. 2A-FIG. 2E.
Ambidextrous stabilizer 220 may include a body that has an upper side, a left side and a right side opposite the left side. The upper side may include a groove or slot extending along a longitudinal direction of the body. The groove or slot may be configured to accommodate an object having a shape similar to an accessory mounting rail (e.g., the attachment portion of buffer tube 110). The upper side of the body may also include a through hole traversing the body and connecting the left side and the right side of the body to allow a pin, a bolt or a screw to secure the object to the body when the object is received in the groove or slot by sliding into the groove or slot along the longitudinal direction.
In some implementations, each of the left side and the right side of the body may include a curved surface which may be a concave surface. The curvature of the curved surface on the left side and the curvature of the curved surface on the right side may be mirror image of each other. This feature allows ambidextrous stabilizer 220 to be equally usable by a right-handed user as well as a left-handed user.
In some implementations, each of the left side and the right side of the body of ambidextrous stabilizer 220 may include a frictional interface. In some implementations, the frictional interface may include a non-slip material, a non-permanent adhesive material, or a felt material. In some implementations, the frictional interface may include a material made of silicone, rubber, nanotubes, or a combination thereof.
FIG. 2F illustrates buffer tube 110 and ambidextrous stabilizer 220 in use with a lower receiver 230 of a firearm 220 in accordance with an implementation of the present disclosure. In the example shown in FIG. 2F, the first distal end (e.g., front end) of buffer tube 110 may be received in lower receiver 230 of firearm 200. Additionally, ambidextrous stabilizer 220 and buffer tube 110 may be mechanically coupled to each other with the attachment portion of buffer tube 110 received in (by sliding into) the groove or slot on the upper side of ambidextrous stabilizer 220.

FIG. 4G illustrates an example of an ambidextrous stabilizer 422 in accordance with an implementation of the present disclosure. That is, ambidextrous stabilizer 422 may be an example implementation of ambidextrous stabilizer 420. Accordingly, ambidextrous stabilizer 422 may be configured with at least those features of ambidextrous stabilizer 420 described above. Referring to FIG. 4G, ambidextrous stabilizer 420 may also include a slit 425. Slit 425 may be configured to allow a lanyard, string or strap to pass through as part of or functioning as part of a sling.

Illustrative Implementations

FIG. 5 illustrates an example scenario 500 of an ambidextrous stabilizer 530 in use in accordance with an implementation of the present disclosure. In example scenario 500, ambidextrous stabilizer 530 may represent any of ambidextrous stabilizer 220, ambidextrous stabilizer 320, ambidextrous stabilizer 420, and any derivatives thereof.
Referring to part (A) of FIG. 5, in example scenario 500 a forearm 510 of a user (not shown) may wear a wearable piece 520 that will come in direct contact with ambidextrous stabilizer 530. Wearable piece 520 may be, for example and without limitation, a part of a long sleeve of a shirt or jacket, a hook-and-loop attachment (e.g., with a Velcro™ hook and a Velcro™ loop), or something that wraps around the forearm 510. In the example shown in FIG. 5, wearable piece 520 is a hook-and-loop attachment with a hook portion 522 and a loop portion 524. When wrapped around the forearm 510, the hook portion 522 and loop portion 524 come in contact with each other to mechanically secure wearable piece 520 to the forearm 510.
Referring to parts (B), (C) and (D) of FIG. 5, with ambidextrous stabilizer 530 installed on a firearm 540 (e.g., an AR-type pistol) and the user holding a pistol grip of firearm 540, wearable piece 520 comes in contact with the frictional interface on the curved surface of the body of ambidextrous stabilizer 530. Friction between wearable piece 520 and the frictional interface help reduce movement of ambidextrous stabilizer 530 relative to forearm 510, thereby achieving stabilization of firearm 540 by reducing forward and backward movements as well as pivotal movements of firearm 540 relative to forearm 510.
It is noteworthy that, although the forearm 510 appears to be the right forearm of the user, example scenario 500 is equally applicable when the user uses the left forearm in conjunction with ambidextrous stabilizer 530.

Additional Notes

The herein-described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely examples, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected”, or “operably coupled”, to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “operably couplable”, to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components and/or wirelessly interactable and/or wirelessly interacting components and/or logically interacting and/or logically interactable components.
Further, with respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
Moreover, it will be understood by those skilled in the art that, in general, terms used herein, and especially in the appended claims, e.g., bodies of the appended claims, are generally intended as “open” terms, e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc. It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to implementations containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an,” e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more;” the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number, e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations. Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc. In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc. It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
From the foregoing, it will be appreciated that various implementations of the present disclosure have been described herein for purposes of illustration, and that various modifications may be made without departing from the scope and spirit of the present disclosure. Accordingly, the various implementations disclosed herein are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
