DETAILED DESCRIPTION OF THE PRESENT DISCLOSURE

The foregoing and other objectives, features, and advantages of the invention will be more readily understood upon consideration of the following description of the invention taken in conjunction with the accompanying drawings.

For simplicity and clarification, the design factors and operating principles of the safety selector levers according to the present disclosure are explained with reference to various exemplary embodiments of safety selector levers according to the present disclosure. The basic explanation of the design factors and operating principles of the safety selector levers is applicable for the understanding, design, and operation of the safety selector levers of the present disclosure. It should be appreciated that the safety selector levers can be adapted to many applications where a safety selector lever is necessary or desirable.

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 “illuminated”, “visually distinguishable”, “safety selector”, “lever”, and “firearm” are used for basic explanation and understanding of the operation of the systems, methods, and apparatuses of the present disclosure. Therefore, the terms “illuminated”, “visually distinguishable”, “safety selector”, “lever”, and “firearm” are not to be construed as limiting the systems, methods, and apparatuses of the present disclosure.

For simplicity and clarification, the safety selector levers of the present disclosure will be described as being used as a safety selector lever for an AR-15 or M4 style firearm. However, it should be appreciated that these are merely exemplary embodiments of the safety selector levers and are not to be construed as limiting the present disclosure. Thus, the safety selector levers of the present disclosure may be utilized in connection with any firearm or other device using a safety selector lever.

Turning now to the drawing FIGS., FIGS. 1-17 illustrate certain components, elements, and/or aspects of certain exemplary embodiments of the safety selector lever 100, according to the present disclosure, while FIGS. 18-27 illustrate certain components, elements, and/or aspects of certain exemplary embodiments of the safety selector lever 200, according to the present disclosure.

In illustrative, non-limiting embodiment(s) of the present disclosure, the safety selector lever 100 comprises at least some of a lever element 110 and a visual element 150. The lever element 110 includes a head portion 120 and an extension portion 130.

As illustrated, the head portion 120 includes at least some of an attachment element 123 formed within a portion of the head portion 120. The attachment element 123 is defined by at least one or more recess sidewalls 125 and a recess bottom wall 124. At least a portion of the attachment element 123 is formed so as to be slidably or otherwise mateable with portions of a projection of a selector core.

In this manner, interaction between the attachment element 123 and the projection of the selector core ensure that the lever element 110 is rotated with the selector core. Thus, the interaction of the selector core and the attachment element 123 ensures that the selector core and the lever element 110 do not rotate separate or apart from one another and rotational movement of the lever element 110 is transmitted directly to the selector core.

In the illustrated embodiment, a compression screw aperture 126 is formed through the recess bottom wall 124 of the lever element 110. Typically, the compression screw aperture 126 is formed within the head portion 120 and is centered relative to the attachment element 123. In various exemplary embodiments, the compression screw aperture 126 includes a tapered portion as the compression screw aperture 126 extends from the attachment element 123. In this manner, a portion of a compression screw is able to be centered relative to the compression screw aperture 126.

When the projection of the selector core and the attachment element 123 are appropriately aligned, the attachment element 123 is appropriately mated with the projection of the selector core. Thus, a hex key (or other appropriate driver or device) is capable of being positioned through the compression screw aperture 126 to interact with a compression screw to maintain an appropriately aligned positioned between the selector core and the lever element 110 and resist slidable movement of the lever element 110 relative to the selector core.

While this exemplary embodiment of the head portion is illustrated and described, it should be appreciated that the safety selector lever 100 of the present disclosure is not so limited. Therefore, it should be understood that the head portion 120 may include any presently known or later discovered attachment or coupling device or system for attaching or coupling the safety selector lever 100 to a desired selector core. Thus, a projection, extension, or recess may extend from or be formed in a portion of the head portion 120 so as to allow the safety selector lever 100 to be attached or coupled to a selector core.

The extension portion 130 includes an extension portion top wall 131, extension portion sidewalls 133, and an extension portion bottom wall 135.

In various exemplary embodiments, the extension portion 130 extends from the head portion 120. Alternatively, at least a portion of the extension portion 130 may overlap at least a portion of the head portion 120. As illustrated by comparing the lever element 110 in FIGS. 1-13 and the lever element 110′ in FIGS. 14-15, the length of the extension portion 130 may be varied such that the extension portion 130 may be comparatively longer or shorter, depending upon the desired application.

It should also be appreciated that various extension portions 130 may include different features, when compared to one another. For example, by altering the length, thickness, or configuration of the extension portion 130, a user may be able to select a lever element 110 that is most satisfactory to the shooter. Thus, a plurality of interchangeable lever elements 110 may be provided and a desired lever element 110 may utilized in conjunction with a selector lever core (not shown).

In certain exemplary embodiments, a plurality of diagonal grooves 138 are formed within a portion of the extension portion sidewalls 133 of the lever element 110. The grooves 138, if included, serve to provide texturing to portions of the extension portion 130 to prevent a user's finger from slipping off the extension portion 130 of the lever element 110.

A visual element recess 112 is formed through at least a portion of the extension portion 130. In various exemplary embodiments, the visual element recess 112 extends, from an open first end to an open second end, through the entire extension portion 130, along the longitudinal axis, A_L, of the extension portion 130. The visual element recess 112 is formed so as to accept all or at least a portion of a visual element 140 therein. In various exemplary embodiments, the cross-section of the visual element recess 112 is substantially cylindrical.

In certain exemplary embodiments, at least a portion of the sidewall of the visual element recess 112 may include a surface preparation, such as, for example, chrome lining, that provides a reflective or partially reflective surface to enhance the emanation or radiation of the light from the visual element 140.

A securing screw aperture 136 extends from the extension portion bottom wall 135 to the visual element recess 112. The securing screw aperture 136 is at least partially internally threaded. The internal threading of the securing screw aperture 136 is formed so as to allow interaction between the internal threads of the securing screw aperture 136 and external threads of the securing screw 150, such that the securing screw 150 can be repeatably threadably rotated between a disengaged position and an engaged position (as illustrated, for example, in FIG. 12). The securing screw aperture 136 extends so as to allow an entire securing screw 150 to be received therein, such that when the securing screw 150 is in the engaged position, a terminal end of the securing screw 150 extends so as to contact and engage at least a portion of a visual element 140 positioned within the visual element recess 112.

In various exemplary embodiments, the securing screw 150 is similar to a threaded head plug. In various exemplary embodiments, the securing screw 150 comprises a hex head socket threaded plug, such as, for example, a 4-48 set screw. It should be appreciated that other threaded plugs may be utilized, but by utilizing a securing screw 150 similar to a hex head socket threaded plug, a hex key, Allen key, or other similar device can be used to engage and rotate the securing screw 150.

The securing screw 150 may optionally include a portion of Teflon, rubber, or other material extending from the terminal end of the securing screw 150. In this manner, the chance of the securing screw 150 marring or damaging the visual element 140 is reduced.

In various exemplary, nonlimiting embodiments, the visual element 140 may optionally transmit light either by self-illumination or by concentrating ambient light. In various exemplary embodiments, the visual element 140 may comprise a substance which can absorb energy and release the energy in the form of light. For example, the visual element 140 may optionally provide illumination by photoluminescence, phosphorescence, fluorescence, chemiluminescence. In certain exemplary embodiments, the visual element 140 may comprise a self-illuminating material, such as, for example, tritium or tritium gas, encased within a cylinder. Alternatively, the visual element 140 may comprise a fiber optic strand or cylinder that is able to collect ambient light and concentrate the collected light to “glow”. In various exemplary embodiments, the visual element 140 takes the form of an elongate or elongated cylinder. However, it should be appreciated that the overall size and shape of the visual element 140 is such that it can be positioned within or at least partially within the visual element recess 112. In an exemplary, nonlimiting embodiment, the visual element 140 comprises a 0.04 inch or a 0.06 inch diameter colored optic rod.

In certain exemplary embodiments, the visual element 140 comprises a self-illuminating material or a fiber optic material. The visual element 140 may optionally provide illumination by photoluminescence, phosphorescence, fluorescence, or chemiluminescence.

In certain exemplary embodiments, the visual element 140 comprises a rod or element having a luminous phosphorescent paint applied to at least a portion of the exterior surface of the rod or element.

In certain exemplary embodiments, the visual element 140 comprises a non-luminescent rod or element. The visual element 140 may optionally be colored or at least partially colored to provide a visually discernible contrast between the visual element 140 and other surfaces of the lever element 110. The visual element 140 may optionally comprise a material, such as, for example, steel, stainless steel, copper, brass, or the like, which provides a visually discernible contrast between the visual element 140 and other surfaces of the lever element 110.

A primary viewing aperture 132 extends, along at least a portion of the extension portion 130, from the extension portion top wall 131 to at least a portion of the visual element recess 112. The primary viewing aperture 132 extends so as to allow light from a visual element 140, positioned within the visual element recess 112, to emanate or radiate from the visual element recess 112, through the primary viewing aperture 132.

In certain exemplary embodiments, one or more secondary viewing apertures 134 extend, along at least a portion of the extension portion 130, from one or both of the extension portion sidewalls 133 to at least a portion of the visual element recess 112. The secondary viewing apertures 134 extend so as to allow light from a visual element 140, positioned within the visual element recess 112, to emanate or radiate from the visual element recess 112, through the secondary viewing apertures 134. As illustrated in FIGS. 1-13, two secondary viewing apertures 134 are formed in each extension portion side wall 133. Optionally, the secondary viewing apertures 134 are formed directly across from one another and each extends through a portion of the visual element recess 112. Alternatively, as illustrated in FIGS. 14-15, the lever element 110′ only includes a single secondary viewing aperture 134 is formed in each extension portion side wall 133.

As illustrated in FIGS. 15-16, the lever element 110″ only includes a primary viewing aperture 132 and does not include any secondary viewing apertures 134. It should also be understood and appreciated that the lever element 110 may only include secondary viewing apertures and not include a primary viewing aperture. Thus, it should be appreciated that the number and placement of any primary viewing apertures and/or secondary viewing apertures is a design choice, based upon the desired illumination level and/or functionality of the safety selector lever 100.

In various exemplary embodiments, the lever element 110 is substantially rigid and formed of stainless steel. Alternate materials of construction of the lever element 110 may include one or more of the following: steel, aluminum, titanium, and/or other metals, as well as various alloys and composites thereof, glass-hardened polymers, polymeric composites, polymer or fiber reinforced metals, carbon fiber or glass fiber composites, continuous fibers in combination with thermoset and thermoplastic resins, chopped glass or carbon fibers used for injection molding compounds, laminate glass or carbon fiber, epoxy laminates, woven glass fiber laminates, impregnate fibers, polyester resins, epoxy resins, phenolic resins, polyimide resins, cyanate resins, high-strength plastics, nylon, glass, or polymer fiber reinforced plastics, thermoform and/or thermoset materials, and/or various combinations of the foregoing. Thus, it should be understood that the material or materials used to form the lever element 110 is a design choice based on the desired appearance and functionality of the lever element 110.

It should be appreciated that certain elements of the lever element 110 may be formed as an integral unit (such as, for example, the head portion 120 and the extension portion 130). Alternatively, suitable materials can be used and sections or elements made independently and attached or coupled together, such as by adhesives, welding, screws, rivets, pins, or other fasteners, to form the various elements of the lever element 110.

It should also be understood that the overall size and shape of the lever element 110 is a design choice based upon the desired functionality and/or appearance of the lever element 110.

During assembly of the safety selector lever 100, as illustrated most clearly in FIGS. 10-13, the visual element 140 is aligned with and urged into the visual element recess 112. Once the visual element 140 is appropriately positioned within the visual element recess 112, the securing screw 150, which may already be at least partially threadedly inserted within the securing screw aperture 136, is further threadedly inserted within the securing screw aperture 136 and rotated (typically clockwise) so as to be moved from the disengaged position, with the terminal end of the securing screw 150 positioned flush or outside of the visual element recess 112, to the engaged position. In the disengaged position, the securing screw 150 does not interfere with the ability of the visual element 140 to be slidably inserted within the visual element recess 112. When rotated to the engaged position, at least a terminal end of the securing screw 150 is urged against a portion of the visual element 140 to further assist in maintaining the visual element 140 within the visual element recess 112 and resist slidable movement of the visual element 140 relative to the visual element recess 112.

In certain exemplary embodiments, the securing screw aperture 136 and the securing screw 150 are not included and the visual element 140 may be retained within the visual element recess 112 via frictional engagement between one or more exterior surfaces of the visual element 140 and one or more surfaces defining of the visual element recess 112. Additionally, the visual element 140 may be retained within the visual element recess 112 via, for example, an adhesive or mushrooming of terminal ends of the visual element 142 maintain the visual element 140 within the visual element recess 112.

If a user desires to remove and/or replace a visual element 140, the securing screw 150 is rotated from the engaged position to the disengaged position. Once the securing screw 150 is in the disengaged position, the visual element 140 can be slidably removed from the visual element recess 112 and replaced, if desired, by an alternative visual element 140.

It should also be appreciated that a more detailed explanation of the specific dimensions of certain components of the safety selector lever 100, instructions regarding how to install the safety selector lever 100, methods for using the safety selector lever 100, once installed, and certain other items and/or techniques necessary for the implementation and/or operation of the various exemplary embodiments of the present disclosure are not provided herein because such background information will be known to one of ordinary skill in the art. Therefore, it is believed that the level of description provided herein is sufficient to enable one of ordinary skill in the art to understand and practice the systems, methods, and apparatuses of the presentation, as described.

It should be appreciated that the compression screw attachment system of the present disclosure is not limited to the embodiment illustrated and described as the safety selector lever 100. For example, FIGS. 18-27 illustrate certain components, elements, and/or aspects of certain exemplary embodiments of the safety selector lever 200, according to the present disclosure. The safety selector lever 200 comprises at least some of a lever element 210, a head portion 220, an attachment element 223, a recess bottom wall 224, recess sidewalls 225, an extension portion 230, an extension portion top wall 231, extension portion side walls 233, an extension portion bottom wall 235, and optionally including diagonal grooves 238.

It should be appreciated that these elements correspond to and operate similarly to the lever element 210, the head portion 220, the attachment element 223, the recess bottom wall 224, the recess sidewalls 225, the extension portion 230, the extension portion top wall 231, the extension portion side walls 233, the extension portion bottom wall 235, and the optional diagonal grooves 238, as described, with reference to the safety selector lever 100.

As discussed with reference to the safety selector lever 100, the length of the extension portion may vary, as illustrated by the varied length when comparing the lever element 210 of FIGS. 18-25 and the lever element 210′ of FIGS. 26-27.

However, as illustrated FIGS. 18-27, the lever element 210 includes a visual element recess 212 that extends from the extension portion top wall 231 toward the extension portion bottom wall 235. The visual element recess 212 is formed so as to allow a visual element 240 to be positioned therein. The visual element 240 transmits light either by self-illumination or by concentrating ambient light. In various exemplary embodiments, the visual element 240 may comprise a substance which can absorb energy and release the energy in the form of light. For example, the visual element 240 may optionally provide illumination by photoluminescence, phosphorescence, fluorescence, chemiluminescence. In certain exemplary embodiments, the visual element 240 may comprise a self-illuminating material, such as, for example, tritium or tritium gas, encased within a cylinder. Alternatively, the visual element 240 may comprise a fiber optic portion that is able to collect ambient light and concentrate the collected light to “glow”. It should be appreciated that the overall size and shape of the visual element 240 is such that it can be positioned within or at least partially within the visual element recess 210.
