DETAILED DESCRIPTION

Before turning to the figures, which illustrate the exemplary embodiments in detail, it should be understood that the present disclosure is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology used herein is for the purpose of description only and should not be regarded as limiting.

Overview

Referring generally to the figures, a handguard for a firearm includes a body member, a first end member, a second end member, and multiple elongated members or rods that extend through an inner volume of the body member. The body member and the rods may extend in a same direction such that the body member and the rods are parallel with each other. The first end member fixedly couples with the body member at a first end of the body member (an end proximate a receiver of the firearm). The second end member fixedly couples with the body member at a second end of the body member (an end distal a receiver of the firearm). The first end member and the second end member may include one or more openings, windows, apertures, etc., through which a barrel and/or gas-system of the firearm extend. The first end member may engage the barrel through an opening and an interior surface. For example, the interior surface may directly contact, abut, engage, be press-fit, be slip-fit, etc., with a corresponding portion of the barrel. In some embodiments, the barrel is free-floating within the handguard.

The rods can be fastened or otherwise fixedly coupled at opposite ends with the first end member and the second end member and may extend through the inner volume of the body member. The rods may facilitate reducing or eliminating an amount of load applied to the body member being transferred to the barrel, which can result in bending or deformation of the barrel and adversely affect accuracy of the firearm. The handguard may be a free-floating handguard.

In various conventional firearms, the handguards attach to a receiver of the firearm at an aft end, and to the barrel at the front end. Because of this arrangement, any force or load applied on the handguards (e.g., by a user, during operation of the firearm) may be transmitted to the barrel, causing it to bend slightly and cause a reduction in accuracy.

In many firearms it is desirable to have the handguard be free-floating and not rely on any support from or connection to the barrel in order to reduce a likelihood that the force or load at the handguards is transferred to the barrel. A free-floating handguard generally only attaches to the firearm at one surface, usually its aft end. This may require that the entire handguard either be made from one piece or is a weldment or assembly. A weldment requires that the handguard be made from materials which can be welded. Common materials for the handguard body can be extruded aluminum, bent-up or pressed aluminum or steel, plastic, carbon fiber, magnesium.

The handguard described herein is an assembly that is formed by fixedly coupling end caps to the ends of the handguard body, which (other than being hollow to allow the barrel, gas system, etc., to pass through it) can be of virtually any shape. The handguard body is encapsulated between the fore and aft end caps using any of, or any combination of rods, wires, cables, spokes, or any other elongated member that can be loaded in tension. The endcaps facilitate attaching of the rods, wires or spokes by holes (threaded or otherwise) or features which engage them by mating threads or features. Advantageously, using the rods may facilitate allowing the body member being manufactured from non-weldable materials if desired, and facilitates reducing or eliminating an amount of load transferred to the barrel through the body member. The rods may also provide additional structural support or strength for the body member.

Firearm

Referring to FIGS. 1-7, a firearm 100 is shown, according to an exemplary embodiment. The firearm 100 can be a semi-automatic firearm (e.g., a semi-automatic rifle) or a fully-automatic firearm (e.g., a fully-automatic rifle). It should be understood that the firearm 100 can be any other style of firearm and the example shown in FIGS. 1-7 should not be understood to be limiting.

The firearm 100 includes a stock 110, a grip 102 (e.g., a pistol grip, a hand grip, etc.), a lower receiver 104, and upper receiver 108, a trigger assembly 106, and a barrel 32. The firearm 100 also includes a handguard 10 (e.g., a grasping portion, a sleeve portion, a grip, etc.) through which the barrel 32 extends. The firearm 100 may be operated by placing the stock 110 against a user's shoulder and through operation of a trigger of the trigger assembly 106. The handguard 10 may provide a surface for steadying and aiming the firearm 100 (e.g. being grasped with a user's hand). The firearm 100 can be an M-16 and/or an AR-15 rifle.

Firearm Handguard

Referring particularly to FIG. 8, the handguard 10 (e.g., a grasping portion, a sleeve portion, a grip, etc.) for a firearm (e.g., the firearm 100 of FIGS. 1-7) is shown, according to an exemplary embodiment. Handguard 10 can be configured for use with any type of firearm such as a semi-automatic firearm (e.g., a semi-automatic rifle), or a fully-automatic firearm. It should be understood that handguard 10 can be configured for use with any style of firearm (such as the firearm 100 shown in FIGS. 1-7) and the examples of a semi-automatic firearm or a fully-automatic firearm should not be understood to be limiting.

Handguard 10 may be an elongated hollow member including an inner volume 30 that extends through handguard 10. Handguard 10 includes a front end, a front portion, a forward portion, a fore end, etc. shown as first end 20, and a rear end, a back end, a back portion, a rear portion, an aft end, etc., shown as second end 22. Handguard 10 includes a body member 12 (e.g., a main member, a sidewall member, a tubular member, a hollow member, an elongated member, a shell, etc.), a first end member 14 (e.g., an end cap, a hollow member, a structural member, etc.), and a second end member 16 (e.g., an end cap, a hollow member, a structural member, etc.). First end member 14 may be positioned at first end 20 and may be fixedly coupled, attached, secured, fastened, etc., with first end 20 of body member 12. Likewise, second end member may be positioned at second end 22 and may be fixedly coupled, attached, secured, fastened, etc., with second end 22 of body member 12. First end member 14 can be configured to fixedly couple (e.g., removably attach, interlock, be fastened with, etc.), with a receiver or other portion of the firearm. Body member 12 may include multiple openings 40 on one or more sides that extend through a wall thickness or at least partially through the wall thickness of body member 12. Openings 40 may facilitate reducing a weight of body member 12 and improved heat dissipation. Openings 40 can be positioned and sized on body member 12 according to a standard rail interface system. For example, openings 40 can facilitate mounting of accessories on handguard 10 such as bipods, optics, scopes, etc., which may include fasteners, interlocking portions, etc., that extend into openings 40. As shown, body member 12 may have a generally rectangular cross-sectional shape. In other embodiments, body member 12 may have an elliptical, irregular, square, non-uniform, circular, etc., cross-sectional shape. In some embodiments, a cross-sectional shape of body member 12 varies or changes across a length of body member 12.

First end member 14 may have a cross-sectional shape that corresponds to the cross-sectional shape of body member 12 or the cross-sectional shape of body member 12 at first end 20. Likewise, second end member 16 can have a cross-sectional shape that corresponds to the cross-sectional shape of body member 12 or the cross-sectional shape of body member 12 at second end 22. First end member 14 and second end member 16 may be configured to interlock with body member 12 at first end 20 and second end 22 of body member 12, respectively.

A longitudinal axis 18 extends through a center of handguard 10 or a center or body member 12. Longitudinal axis 18 may define a longitudinal direction. Handguard 10 also includes rods 24 (e.g., rods, elongated members, cylindrical members, wires, thin members, spokes, cables, tensile members, etc.) that extend through inner volume 30 of body member 12. Rods 24 can extend in a direction that is parallel or substantially parallel with longitudinal axis 18 of body member 12. Rods 24 may be or function similarly to bicycle spokes and can facilitate reducing an amount of load that is transferred to a barrel 32 of the firearm. Loads that are transferred to barrel 32 of the firearm can adversely affect an accuracy of the firearm. It should be understood that the rods 24 described herein may be any of rods, elongated members, cylindrical members, wires, thin members, spokes, cables, tensile members, etc., or any combination thereof. It should be understood that the term “elongated members” as used herein may refer to any of, or any combination of, rods, cylindrical members, wires, thin members, spokes, cables, tensile members, etc.

In various conventional firearms, handguards may be fixedly coupled with the barrel of the firearm at their fore or front ends and fixedly coupled with the firearm receiver at their aft or rearwards ends. However, such a configuration may result in any force applied to the handguard being transferred or transmitted to the barrel, which may cause the barrel to bend slightly and can adversely affect an accuracy of the firearm.

Referring particularly to FIG. 9, rods 24 may extend along substantially an entire longitudinal length of body member 12 through inner volume 30. Rods 24 may extend between first end member 14 and second end member 16. In the exemplary embodiment shown in FIGS. 1-4, rods 24 extend from first end member 14 to second end member 16 and are each fixedly coupled with first end member 14 at a first or proximate end and are fixedly coupled with second end member 16 at a second or distal end. Rods 24 may extend through inner volume 30 of body member 12 proximate or adjacent to an interior surface of body member 12. In the exemplary embodiment shown in FIGS. 1-4, four rods 24 are used, which extend proximate to four corner portions of body member 12. In other embodiments, more or less than four rods 24 are used, each of which may extend longitudinally through inner volume 30. In some embodiments, rods 24 are positioned to extend along the interior surface of body member 12, or are partially enclosed within a corresponding track, groove, channel, recess, etc., of body member 12. Rods 24 may also be integrated or at least partially positioned within a sidewall of body member 12. In other embodiments, rods 24 extend longitudinally along or proximate an exterior surface of body member 12.

Referring still to FIG. 9, rods 24 can be fixedly coupled, attached, fastened, secured, etc., with second end member 16 at second end 22 of handguard 10. Rods 24 may be fixedly coupled with fasteners 26 that are positioned at corresponding attachment portions 36 of second end member 16. Fasteners 26 can include a central opening, an aperture, a hole, etc., configured to receive a corresponding end of rods 24. Attachment portions 36 can each include an opening, aperture, hole, bore, cavity, etc., through which rods 24 extend. Attachment portions 36 can also include threads configured to threadingly couple with corresponding threads of fasteners 26. In some embodiments, a tensile load on each of rods 24 can be independently adjusted by adjustment or fasteners 26 (e.g., by tightening or loosening fasteners 26). For example, rotating fasteners 26 clockwise or counterclockwise (depending on a direction of the threads of fasteners 26) may increase or decrease a tensile load applied to rods 24 between first end member 14 and second end member 16.

Referring particularly to FIGS. 10 and 11, respectively, a front view and a rear view of handguard 10 are shown. Rods 24 are fixedly coupled with first end member 14 (as shown in FIG. 4) at their first ends and are fixedly coupled with second end member 16 (as shown in FIG. 3) at their second ends.

Referring particularly to FIG. 11, rods 24 are fixedly coupled with first end member 14 through fasteners 28. Fasteners 28 may be the same as or similar to fasteners 26 at second end member 16. Fasteners 28 may include an opening, aperture, receiving portion, bore, window, etc., configured to receive an end of a corresponding rod 24. Fasteners 28 may also be adjustable to increase or decrease a tensile load applied to rods 24 (e.g., independently adjustable).

First end member 14 can include a radially inwards surface, an inner periphery, an interior surface, an inwards facing surface, etc., shown as inner surface 34. Inner surface 34 may be an interior surface of a bore, an opening, a window, an aperture, etc., shown as aperture 38. Aperture 38 may be configured to receive barrel 32 therethrough. An inner diameter of aperture 38 may be substantially equal to an outer diameter of a corresponding portion of barrel 32. Inner surface 34 can be configured to engage, directly contact, etc., an exterior surface of the corresponding portion of barrel 32.

It should be understood that while first end member 14 and second end member 16 are shown having a specific shape, first end member 14 and second end member 16 can have any shape, provided first end member 14 and second end member 16 include an opening, inner volume, window, aperture, etc., through which barrel 32 and various components of a gas-system of the firearm can extend (e.g., if the firearm includes a gas-system). Handguard 10 may also be configured for use with firearms that do not include a gas-system such as a bolt-action firearm, a lever action firearm, etc., or any other type of firearm.

Referring again to FIGS. 8-11, handguard 10 includes rods 24 that extend between first end member 14 and second end member 16 and are fixedly coupled at opposite ends through fasteners 26 and fasteners 28. Fasteners 26 and fasteners 28 may be threaded nuts, rivets, or any other type of fasteners. Handguard 10 may be manufactured from any steel, aluminum, composite, plastic, etc., material. Handguard 10 may fixedly couple or engage barrel 32 at only one end (e.g., at first end 20 through first end member 14). Handguard 10 can be fixedly coupled with a receiver (e.g., the upper receiver 108) of the firearm at a same end that engages barrel 32. In other embodiments, handguard 10 can fixedly couple with or engage barrel 32 at both ends or at a position between first end 20 and second end 22.

Referring to FIGS. 8-11, in another embodiment the handguard 10 is coupled directly with the firearm 100 directly using the rods 24 (e.g., without using the second end member 16 and/or the first end member 14). In another embodiment, the handguard 10 includes both the body member 12 and the second end member 16 (e.g., a forward end cap) without using the first end member 14. In such a configuration, the handguard 10 couples with the firearm 100 (e.g., with the upper receiver 108) through the rods 24 that extend out of the first end 20 of the body member 12. In some embodiments, the handguard 10 includes the body member 12, the rods 24, and one or both of the first end member 14 and the second end member 16 or neither. For example, the rods 24 may couple with a portion of the body member 12 at opposite ends instead of coupling with the first end member 14 and the second end member 16. The handguard may include (1) the body member 12, the first end member 14, the second end member 16, and the rods 24, (2) the body member 12, the first end member 14, and the rods 24, (3) the body member 12, the second end member 16, and the rods 24, or (4) the body member 12 and the rods 24. In any of such configurations, the rods 24 may fixedly couple with a corresponding portion of the body member 12 instead of the first end member 14 or the second end member 16. For configurations where the first end member 14 is not used, the rods 24 can directly couple with the firearm 100 (e.g., the upper receiver 108).

Advantageously, handguard 10 may include rods 24 which provide structural support for body member 12 between first end member 14 and second end member 16. In some embodiments, rods 24 are loaded in tension, thereby compressing body member 12 between first end member 14 and second end member 16. Rods 24 may facilitate reducing an amount of load applied to body member 12 (e.g., by a user of the firearm) being transferred to barrel 32 which may cause barrel 32 to deform or bend and adversely affect accuracy of the firearm. Rods 24 in combination with engaging barrel 32 at first end member 14 may further facilitate reducing the loads applied at body member 12 being transferred to barrel 32. Advantageously, rods 24 and engaging barrel 32 at first end member 14 can facilitate reducing loads to barrel 32, thereby decreasing a likelihood that loads are transferred to barrel 32 (which may compromise an accuracy of the firearm).

As described herein, handguard 10 is an assembly including body member 12, first end member 14, second end member 16, rods 24, and fasteners 26 and 28. Advantageously, using rods 24 allows body member 12 to be a free-floating handguard that does not require a weldable material. Body member 12 may be manufactured from a lightweight composite, a polymer, a plastic, aluminum, steel, etc., while rods 24 may provide additional structural strength for body member 12 and reduce an amount or a likelihood that loads or forces applied at body member 12 are transferred to barrel 32.
