BACKGROUND OF THE INVENTION
1. Field of the Invention
The present disclosure relates generally to the field of firearms. More specifically, the present disclosure relates to an ambidextrous charging handle adaptable to be used with a firearm, such as the AR-15, M4, and the like.
2. Description of Related Art
The AR-15 is based on the AR-10, which was designed by Eugene Stoner, Robert Fremont, and L. James Sullivan of the Fairchild ArmaLite Corporation in 1957. Today, there are numerous variants of the AR-15 that are manufactured by a number of companies. The AR-15 and its various related derivative platforms are used by civilians, law enforcement personnel, and military forces around the world.
Various firearms, such as, for example, the AR-15 or M-4 style firearms utilize a charging handle, located at top and substantially parallel to the bolt of the firearm, to manipulate the bolt and open the firearm's action and/or manually load a cartridge into the firearm's chamber.
The typical charging handle comprises an elongate portion of material that extends from a substantially T-shaped rear handle to a forward end adapted to engage the firearms bolt.
A spring-loaded, pivoting latch includes a hook or claw that engages a recess in the upper receiver of the firearm, to maintain the charging handle in a closed position relative to the upper receiver of the firearm. The pivoting latch is typically located on the left side of the charging handle and when the spring bias of the pivoting latch is overcome, by a user pulling reward on the left side of the charging handle, engaging the pivoting latch, the latch pivots to an unlocked position and allows the user to pull the charging handle rearward to manipulate the bolt.
Any discussion of documents, acts, materials, devices, articles, or the like, which has been included in the present specification is not to be taken as an admission that any or all of these matters form part of the prior art base or were common general knowledge in the field relevant to the present disclosure as it existed before the priority date of each claim of this application.
BRIEF SUMMARY OF THE INVENTION
Initially, the latch could only be manipulated from the left side of the firearm. Over time, modify charging handles have been developed that include an ambidextrous latch mechanism that allows the latch to be manipulated using a lever located on the right and/or left side of the charging handle. However, known ambidextrous charging handles utilize multiple pivot pins and a pivot at multiple points. Additionally, known ambidextrous charging handles typically include a combined latch and lever, wherein the latch (including the hook or claw) is an integral component of at least one of the levers. This results in an overly complicated design, which is prone to failure at multiple points.
The disadvantages and shortcomings of the prior art are overcome by the features and elements of the ambidextrous charging handle of the present disclosure. The advantages of the present disclosure are preferably attained by providing, in a first, exemplary, nonlimiting embodiment, an ambidextrous charging handle that comprises a charging handle body, a lever element, a latch element, and a spring biasing element.
The charging handle body comprises an elongate portion of material that extends along a longitudinal axis from a substantially T-shaped rear handle to a forward end having a bolt engagement element. The T-shaped rear handle includes a right handle portion and a left handle portion and a handle recess formed so as to slidably receive at least a portion of a lever element. The handle recess includes a slide pin or slide protrusion extending from a bottom wall of the handle recess.
The lever element comprises an elongate portion of material that includes a lever recess formed in a forward portion of the lever element. In various exemplary embodiments, the lever recess is formed at an obtuse angle, Θ, relative to a longitudinal axis of the lever element. An elongate lever channel is formed through a portion of the lever element from a top side to a bottom side, perpendicular to the longitudinal axis of the lever element. The lever channel is shaped so as to interact with the slide pin or slide protrusion to enable the lever element to be slidable forward and rearward, relative to the longitudinal axis of the charging handle, within the handle recess.
The latch element extends from a first portion to a second portion and a claw (including a ramp surface and shoulder) is formed proximate the first portion of the latch element. A latch protrusion is formed proximate the second portion of the latch element. The latch protrusion is formed so as to interact with the lever recess such that movement of the lever element along the longitudinal axis of the charging handle produces lateral (side-to-side), non-pivoting, movement of the latch element relative to the longitudinal axis of the charging handle.
The spring biasing element interacts between an interior side wall of the charging handle body and the lever element to bias the lever element in a forward or locked position. As the lever element is urged rearward, from either the right handle portion or the left handle portion of the charging handle body, the spring bias of the spring biasing element can be overcome to move the latch element from the locked to unlocked position.
In an exemplary, nonlimiting embodiment, the ambidextrous charging handle comprises a charging handle body, a latch element, a first lever element, a second lever element, and a spring biasing element.
The charging handle body comprises an elongate portion of material that extends along a longitudinal axis from a rear handle portion to a forward end having a bolt engagement element. The rear handle portion includes a handle recess formed so as to pivotably receive at least a portion of the latch element, the first lever element, the second lever element, and the spring biasing element. The handle recess includes a slide pin or slide protrusion extending from a bottom wall of the handle recess. Additionally, a camming element extends from the bottom wall of the handle recess.
The latch element extends from a first portion to a second portion and a claw (including a ramp surface and shoulder) is formed proximate the first portion of the latch element. A primary latch protrusion is formed proximate the second portion of the latch element, in a top portion of the latch element, while a secondary latch protrusion is formed proximate the second portion of the latch element, in a bottom portion of the latch element.
The first lever element comprises an elongate portion of material that extends from a latch engagement portion to a finger engagement portion. A slide pin aperture is formed through the latch engagement portion, such that when the slide pin aperture interacts with the slide protrusion, the first lever element is able to be pivoted from a locked position to an unlocked position. The first lever element includes a curved, camming surface formed so as to interact with a secondary latch protrusion of the latch element. A spring engagement protrusion extends from a portion of the first lever element so as to engage and interact with the spring biasing element.
The second lever element comprises an elongate portion of material that also extends from a latch engagement portion to a finger engagement portion. A slide pin aperture is formed through the latch engagement portion, such that when the slide pin aperture interacts with the slide protrusion, the second lever element is able to be pivoted from a locked position to an unlocked position. The second lever element includes a lever recess formed so as to interact with a primary latch protrusion of the latch element. A spring engagement protrusion extends from a portion of the second lever element so as to engage and interact with the spring biasing element.
The primary latch protrusion is formed so as to interact with the lever recess of the second lever element such that rotation of the second lever element about the slide protrusion produces lateral movement of the latch element relative to the longitudinal axis of the charging handle.
The secondary latch protrusion is formed so as to interact with the camming surface of the first lever element such that rotation of the first lever element about the slide protrusion also produces lateral movement of the latch element relative to the longitudinal axis of the charging handle. When the camming surface of the first lever element produces movement of the latch element (via interaction of the secondary latch protrusion and the camming surface), the primary latch protrusion interacts with the lever recess of the second lever element to produce rotational movement of the second lever element.
The spring biasing element interacts between the spring engagement protrusion of the first lever element and the spring engagement protrusion of the second lever element to bias the first lever element and the second lever element against one another in a forward or locked position. As the first lever element and/or the second lever element is urged rearward, the spring bias of the spring biasing element can be overcome to move the latch element from the locked to unlocked position.
Accordingly, the present disclosure separately provides an improved ambidextrous charging handle for firearms.
The present disclosure separately provides an improved ambidextrous charging handle for firearms having a simplified design.
The present disclosure separately provides an improved ambidextrous charging handle for firearms, which provides ambidextrous functions with a single slide pin or slide protrusion.
The present disclosure separately provides an improved ambidextrous charging handle for firearms having a latch element that moves from a locked to an unlocked position in a lateral or linear, nonrotating, fashion.

DETAILED DESCRIPTION OF THE INVENTION
For simplicity and clarification, the design factors and operating principles of the ambidextrous charging handle according to an exemplary embodiment of the present disclosure are explained with reference to various exemplary embodiments of an ambidextrous charging handle according to an exemplary embodiment of the present disclosure. The basic explanation of the design factors and operating principles of the ambidextrous charging handle is applicable for the understanding, design, and operation of the ambidextrous charging handle of the present disclosure. It should be appreciated that the ambidextrous charging handle can be adapted to many applications where an ambidextrous charging handle or strap can be used.
As used herein, the word “may” is meant to convey a permissive sense (i.e., meaning “having the potential to”), rather than a mandatory sense (i.e., meaning “must”). Unless stated otherwise, terms such as “first” and “second” are used to arbitrarily distinguish between the elements such terms describe. Thus, these terms are not necessarily intended to indicate temporal or other prioritization of such elements.
The term “coupled”, as used herein, is defined as connected, although not necessarily directly, and not necessarily mechanically. The terms “a” and “an” are defined as one or more unless stated otherwise.
Throughout this application, the terms “comprise” (and any form of comprise, such as “comprises” and “comprising”), “have” (and any form of have, such as “has” and “having”), “include”, (and any form of include, such as “includes” and “including”) and “contain” (and any form of contain, such as “contains” and “containing”) are used as open-ended linking verbs. It will be understood that these terms are meant to imply the inclusion of a stated element, integer, step, or group of elements, integers, or steps, but not the exclusion of any other element, integer, step, or group of elements, integers, or steps. As a result, a system, method, or apparatus that “comprises”, “has”, “includes”, or “contains” one or more elements possesses those one or more elements but is not limited to possessing only those one or more elements. Similarly, a method or process that “comprises”, “has”, “includes” or “contains” one or more operations possesses those one or more operations but is not limited to possessing only those one or more operations.
It should also be appreciated that the terms “ambidextrous charging handle”, “latch element”, and “lever element” are used for basic explanation and understanding of the operation of the systems, methods, and apparatuses of the present disclosure. Therefore, the terms “ambidextrous charging handle”, “latch element”, and “lever element” are not to be construed as limiting the systems, methods, and apparatuses of the present disclosure.
Turning now to the drawing FIGS., FIGS. 1-24 illustrate various elements and/or aspects of an exemplary embodiment of the ambidextrous charging handle 100, according to this disclosure. FIGS. 25-28 illustrate various elements and/or aspects of an exemplary embodiment of the ambidextrous charging handle 200, FIGS. 29-32 illustrate various elements and/or aspects of an exemplary embodiment of the ambidextrous charging handle 300, FIGS. 33-34 illustrate various elements and/or aspects of an exemplary embodiment of the ambidextrous charging handle 400, and FIGS. 35-46 illustrate various elements and/or aspects of an exemplary embodiment of the ambidextrous charging handle 500, according to this disclosure.
As illustrated in FIGS. 1-24, the exemplary embodiment of the ambidextrous charging handle 100 of the present disclosure comprises a charging handle body 102, a lever element 120, a latch element 130, and a spring biasing element 150.
The charging handle body 102 comprises an elongate portion of material that extends along a longitudinal axis from a substantially T-shaped rear handle to a forward end having a bolt engagement element 103. The T-shaped rear handle includes a right handle portion 105 and a left handle portion 106. A handle recess 104 is formed within the T-shaped rear handle portion and is shaped so as to slidably receive at least a portion of the lever element 120 inside the handle recess 104.
A slide protrusion or slide pin 140 extends from a bottom wall of the handle recess 104. In certain exemplary embodiments, the slide protrusion or slide pin 140 extends from both the bottom wall and a top wall of the handle recess 104. Alternatively, a slide pin aperture 108 may be formed through the charging handle body 102 and the slide protrusion or slide pin 140 may comprise a slide pin 140 positioned within the slide pin aperture 108.
In various exemplary embodiments, the lever element 120 comprises an elongate portion of material that includes a lever recess 125 formed in a forward portion of the lever element 120. In various exemplary embodiments, the lever recess 125 is formed at an obtuse angle, Θ, relative to a longitudinal axis of the lever element 120.
An elongate lever channel 122 is formed through a portion of the lever element 120 from a top side to a bottom side, perpendicular to the longitudinal axis of the lever element 120. The lever channel 122 is shaped so as to interact with the slide protrusion or slide pin 140 to enable the lever element 120 to be slidable forward and/or rearward, relative to the longitudinal axis of the charging handle 100, within the handle recess 104.
In various exemplary embodiments, slide support surfaces 107 are formed within the handle recess 104 so as to provide support or sliding surfaces for the lever element 120.
The latch element 130 extends from a first portion to a second portion and a claw 132 (including a ramp surface 133 and shoulder 134) is formed proximate the first portion of the latch element 130. A latch protrusion 135 is formed proximate the second portion of the latch element 130. The latch protrusion 135 is formed so as to be at least partially received within and interact with the lever recess 125 such that movement of the lever element 120 along the longitudinal axis of the charging handle 100 (forward and backward) produces lateral (side-to-side), non-pivoting, movement of the latch element 130 relative to the longitudinal axis of the charging handle 100.
Because of the relative angles of the interior sidewalls of the lever recess 125 and the exterior sidewalls of the latch protrusion 135, as the lever element 120 is urged from the locked position, as illustrated in FIG. 16, to the unlocked position, as illustrated in FIG. 17, the rearward movement of the lever element 120 (and the lever recess 125) causes one or more of the sidewalls of the lever recess 125 to contact one or more of the sidewalls of the latch protrusion 135 and urged the latch protrusion 135 (and the latch element 130) to move laterally, away from the charging handle body 102.
If included, the spring biasing element 150 interacts between an interior side wall of the charging handle body 102 and the lever element 120 to bias the lever element 120 in a forward or locked position. As the lever element 120 is urged rearward, from either the right handle portion 105 or the left handle portion 106 of the charging handle body 102, the spring bias of the spring biasing element 150 can be overcome to move the latch element 130 from the locked to unlocked position.
In various exemplary embodiments, a spring biasing element 150 comprises a curved portion of spring steel. In certain other exemplary, nonlimiting embodiments, the spring biasing element 150′ comprises one or more compression springs. It should also be understood that the spring biasing element 150 and/or 150′ may optionally comprise a spring, a resilient portion of material, or other element capable of providing a biasing force to the lever element 120.
In various exemplary, nonlimiting embodiments, as illustrated in FIG. 20, one or more alignment protrusions 109 extend within various portions of the handle recess 104 and correspond to mating alignment recesses 129 formed in the lever element 120. If included, the one or more alignment protrusions 109 are aligned with or within the alignment recesses 129 during movement of the lever element 120 along the longitudinal axis of the charging handle 100. It should also be appreciated that the protrusions may extend from the lever element 120 and interact with mating recesses formed in the handle recess 104.
In various exemplary embodiments, a spring biasing element 150 or 150′ is positioned within each of the mating alignment recess 129 to provide spring biasing to the lever element 120.
In certain exemplary embodiments, as illustrated in FIGS. 21-22, the charging handle body 102 may be formed as an integral unit. As illustrated in FIG. 23, the charging handle body 102′ may be formed of at least two portions of material.

FIGS. 55-66 illustrate an exemplary, nonlimiting embodiment of the ambidextrous charging handle 600, according to this disclosure. As illustrated, the exemplary embodiment of the ambidextrous charging handle 600 comprises a charging handle body 602, a latch element 630, a first lever element 621, a second lever element 622, and a spring biasing element 650.
The charging handle body 602 comprises an elongate portion of material that extends along a longitudinal axis from a rear handle portion to a forward end having a bolt engagement element 603. The rear handle portion includes a handle recess 604 formed so as to pivotably receive at least a portion of the latch element 630, the first lever element 621, the second lever element 622, and the spring biasing element 650. The handle recess 604 includes a slide protrusion or slide pin 640 extending from a bottom wall of the handle recess 604. Additionally, a camming element 605 extends from the bottom wall of the handle recess 604.
The latch element 630 extends from a first portion to a second portion and a claw 632 (including a ramp surface 633 and shoulder 634) is formed proximate the first portion of the latch element 630. A primary latch protrusion 635 is formed proximate the second portion of the latch element 630, in a top portion of the latch element 630, while a secondary latch protrusion 636 is formed proximate the second portion of the latch element 630, in a bottom portion of the latch element 630.
The first lever element 621 comprises an elongate portion of material that extends from a latch engagement portion to a finger engagement portion. A pivot aperture 623 is formed through the latch engagement portion, such that when the pivot aperture 623 interacts with the pivot protrusion, the first lever element 621 is able to be pivoted from a locked position to an unlocked position. The first lever element 621 includes a curved, camming surface 629 formed so as to interact with a secondary latch protrusion 636 of the latch element 630. A spring engagement protrusion 627 extends from a portion of the first lever element 621 so as to engage and interact with the spring biasing element 650.
The second lever element 622 comprises an elongate portion of material that also extends from a latch engagement portion to a finger engagement portion. A pivot aperture 624 is formed through the latch engagement portion, such that when the pivot aperture 624 interacts with the pivot protrusion, the second lever element 622 is able to be pivoted from a locked position to an unlocked position. The second lever element 622 includes a lever recess 625 formed so as to interact with a primary latch protrusion 635 of the latch element 630. A spring engagement protrusion 628 extends from a portion of the second lever element 622 so as to engage and interact with the spring biasing element 650.
The first lever element 621 and the second lever element 622 each include recessed surface areas 626 and 626′, respectively, within their respective latch engagement portions such that portions of the first lever element 621 and the second lever element 622 are able to overlap one another. By providing overlapping portions, the lever recess 625 and the camming surface 629 are able to more easily interact with the primary latch protrusion 635 and the secondary latch protrusion 636, respectively.
The primary latch protrusion 635 is formed so as to interact with the lever recess 625 of the second lever element 622 such that rotation of the second lever element 622 about the pivot protrusion produces lateral movement of the latch element 630 relative to the longitudinal axis of the charging handle 600.
The secondary latch protrusion 636 is formed so as to interact with the camming surface 629 of the first lever element 621 such that rotation of the first lever element 621 about the pivot protrusion also produces lateral movement of the latch element 630 relative to the longitudinal axis of the charging handle 600. When the camming surface 629 of the first lever element 621 produces movement of the latch element 630 (via interaction of the secondary latch protrusion 636 and the camming surface 629) the primary latch protrusion 635 interacts with the lever recess 625 of the second lever element 622 to produce rotational movement of the second lever element 622.
The spring biasing element 650 interacts between the spring engagement protrusion 627 of the first lever element 621 and the spring engagement protrusion 628 of the second lever element 622 to bias the first lever element 621 and the second lever element 622 against one another in a forward or locked position. As the first lever element 621 and/or the second lever element 622 is urged rearward, the spring bias of the spring biasing element 650 can be overcome to move the latch from the locked to unlocked position.
In various exemplary embodiments, a spring biasing element 650 comprises a spring. However, it should be appreciated that the spring biasing element 650 may comprise a spring, a resilient portion of material, or other element capable of providing a biasing force to the first lever element 621 and/or the second lever element 622.
