The present invention relates firearm accessories. In particular, the present invention relates to apparatuses for coupling accessories to firearms and methods for forming such apparatuses.
Recent years have seen a significant increase in demand for firearms and firearm-related accessories, for both civilian/recreational and military uses. This increased demand can especially be seen with the increased sales of assault rifles and accessories for use with assault rifles, including slings and sling accessories.
One manner in which accessories, such as slings, are often coupled to such firearms involves the use of quick-detach sling swivels and the sockets associated with such swivels. Typically, the quick-detach sling swivels are connected to the slings by, for example, looping the sling through a loop on the sling swivel, which is then inserted into the socket that is attached to the firearm.
In order to equip a firearm to use quick-detach sling swivels, the suitable sockets are sometimes integrally formed with one of more component on the firearm, such as railed handguards, stocks, receivers, etc. Thus, if a firearm is not previously equipped to make use of quick-detach sling swivels, the user may have to purchase a relatively large and expensive piece of equipment, such as a railed handguard. Alternatively, the user may be able to acquire accessories that attach to other components (e.g., a railed handguard or stock), which provide suitable sockets. However, such accessories usually must be attached to particular mounting structures (e.g., picatinny rails).
The present invention will hereinafter be described in conjunction with the appended drawing figures, wherein like numerals denote like elements, and in which:
The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field and brief description of the drawings, or the following detailed description. It should also be noted that
Referring now to
In the depicted embodiment, the first end 18 of the main piece 16 is substantially “squared off” (i.e., at least in the cross-section shown) while the second end 20 has a rounded, or hemispherical, shape. It should be understood that in other embodiments, the main piece 16, or the body 12 as a whole, may have a different shape than that shown in
At the first end 18 thereof, a socket opening 24 is formed in the main piece 16, and at the second end 20 thereof, a flexible member opening 26 is formed in the main piece 16. As shown, the socket opening 24 and the flexible member opening 26 essentially extend the passageway 22 the entire length of the main piece 16 (i.e., passageway 22 extends from the socket opening 24 to the flexible member opening 26 such that the socket opening 24, the passageway 22, and the flexible member opening 26 are in fluid communication with each other).
Near the first end 18 of the main piece 16 (and/or the socket opening 24), several grooves 28 are formed in (or on) an inner surface 30 of the main piece 16 (or the passageway 22). As described below, the socket opening 24 and the grooves 28 may be used to couple a quick-detach sling swivel to the body 12. That is, the socket opening 24 (and/or the grooves 28) may be configured to form a quick-detach sling socket, as is commonly understood.
Referring to
The main piece 16 may be made of a rigid material, such as aluminum, steel, or a polymer. In some embodiments, the main piece 16 is made of 6061-T6 aluminum alloy and is provided with a type III, hard coat anodizing. The main piece 16, in some embodiments, may have a length (as measured between the first end 18 and the second 20 thereof) of, for example, between about 0.75 inches and 1.50 inches, such as about 1.0 inch.

As is evident in
In some embodiments, a compressible body 46 is positioned within the passageway 22 of the main piece 16 between the crimp 44 and the flexible member opening 26. The compressible body 46 may be a washer made of a compressible material (e.g., rubber) through which the flexible member 14 is inserted (such as shown in the depicted embodiment). However, in other embodiments, the compressible member 46 may be made of different materials and have different shapes (e.g., a foam washer or ring, a steel wire spring, etc.). The compressible body 46 may be sized and shaped such that it is held in place within the passageway 22 (e.g., via friction with the inner surface 30 of the passageway 22) and holds the flexible member 14 in place relative to the passageway 22 (e.g., in the example in which the compressible body 46 is a rubber washer, the opening through the washer may be sized such that the flexible member 14 may be threaded therethrough but a significant amount of force is required to do so). The compressible body 46 may also serve to “cushion” the crimp 44 (and the ends 38 and 40 of the flexible member 14) when a force is applied on the flexible member 14 which pulls the crimp 44 towards the flexible member opening 26, thus increasing the “pull strength” of the flexible member 14, as is described in greater detail below.
Still referring to
In some embodiments, due to the use of a high-strength material in the flexible member 14 (e.g., steel aircraft cable), the presence/position of the compressible body 46, and the ends 38 and 40 of the flexible member 14 being secured within the crimp 44, the flexible member 14 may be provided with a pull strength of more than 430 pounds. That is, in some embodiments, the flexible member 14 may be pulled away from the body 12 of the sling-attachment apparatus 10 with a force of greater than 430 pounds before the flexible member 14 will “break loose” from the body 12 (such as by the ends 38 and 40 of the flexible member 14 becoming dislodged from the crimp 44, thus allowing the ends 38 and 40 to be pulled through the flexible member opening 26).
As shown in
The protrusion 56 includes one or more locking members 58 coupled to and/or extending through the side(s) thereof, as shown in

Referring now to
The quick-detach sling swivel 50 may be decoupled (or disconnected) from the body 12 by again actuating the button 60 and pulling the quick-detach sling swivel 50 away from the body 12.
Referring specifically to
It should also be noted that when the quick-detach sling swivel 50 is connected to the body 12, the ends 38 and 40 of the flexible member 14 (or the first portion of the loop formed thereby) and the protrusion 56 on the hub 52 of the quick-detach sling swivel 50 are all positioned within the main piece 16 of the body 12. More particularly, in the embodiment shown, the ends 38 and 40 of the flexible member 14 and the protrusion 56 on the hub 52 are positioned within a single chamber (i.e., partially formed by the passageway 22 in the main piece 16 of the body 12). Further, it should be noted that when the quick-detach sling swivel 50 is not connected to the body 12, the ends 38 and 40 of the flexible member 14 may be held in place within the passageway 22 by the compressible body 46 (i.e., so that the body 12 does not “ride up” the flexible member 14 which may result in the ends 38 and 40 of the flexible member 14 being pushed out of the passageway 22 through the socket opening 24). As such, regardless of whether or not the quick-detach sling swivel 50 is connected to the body 12, the ends 38 and 40 of the flexible member 14 and the crimp 44 may remain protected within the main piece 16 (i.e., thus preventing any damage to the crimp 44 and reducing the likelihood that the crimp 44 may get caught/snagged on an external object).
In use, the sling-attachment apparatus 10 may be attached to virtually any device, such as a firearm. The sling-attachment apparatus 10 provides a lightweight, compact, and easy to install/attach (and uninstall/detach) quick-detach sling socket (as is formed by the socket opening 24 at the first end 18 of the main piece 16 of the body 12) for the device. In particular, the sling-attachment apparatus 10 may be easily attached to the device without making any modifications to the device itself. It should be noted that although the examples described below all refer to the sling-attachment apparatus 10 being attached to firearms, the sling-attachment apparatus may be attached to other types of weapons, such as bows. Further, the sling-attachment apparatus may be used on devices that are not related to weapons at all, such as carrying cases, backpacks, musical instruments, etc.
To attach the sling-attachment apparatus 10, a portion of the device to which it is being attached may simply be inserted through the loop formed by the flexible member 14. Alternatively, the body 12 may be inserted/fed/threaded (or “looped”) through the loop formed by the flexible member 14 after the flexible member 14 has been wrapped around a portion of the device. When used as such, the cinch 48 may be used to prevent the sling-attachment apparatus 10 from accidentally being detached from the device by, for example, preventing the body 12 from becoming “unlooped” through the flexible member 14. The cinch 48 may also serve to simply keep the flexible member 14 in a relatively sleek and compact arrangement (e.g., to prevent the flexible member 14 from getting caught or snagged on an external object).
After the sling-attachment apparatus 10 is attached to the device, a quick-detach sling swivel (such as that described above), or any component utilizing a similar coupling interface (e.g., the protrusion 56 with the locking members 58), may be repeatedly connected to/disconnected from the device (via the body 12) as described above. In embodiments in which a quick-detach sling swivel is used, a sling (e.g., a rifle sling) may be threaded through the sling loop 54 of the quick-detach sling swivel 50, allowing the sling to be quickly and easy connected to/disconnected from the device.
For example, the sling-attachment apparatus 10 may be used to attach a sling to a “front sight base” (FSB) of a Stoner-design rifle (e.g., an AR-15 or a M4 carbine). In particular, the sling-attachment apparatus 10 may be attached to the FSB 102 by “looping” the body thereof through the flexible member after the flexible member has been wrapped around a portion of the FSB. The sling may be threaded through the sling loop of a quick-detach sling swivel 50 that is connected to the body of the sling-attachment apparatus 10 in a manner similar to that described above.
As another example, the sling-attachment apparatus 10 (along with a quick-detach sling swivel 50) may be used to attach a sling to a receiver extension (or buffer tube) of a Stoner-design rifle. In one particular example, the receiver extension may be simply inserted through the loop formed by the flexible member of the sling-attachment apparatus 10. As a further example, the sling-attachment apparatus 10 may be used to attach a sling to a delta ring assembly of a Stoner-design rifle or a butt stock (or stock) or a Stoner-design rifle.
As a yet further example, the sling-attachment apparatus 10 may be used to attach a sling to a front sling loop of an AK-47 (or AKM) rifle or a rear sling loop on a stock of an AK-47 rifle. Additionally, the sling-attachment apparatus 10 may be attached to the stock of an AK-47 rifle by, for example, simply “looping” the body thereof through the flexible member after the flexible member has been wrapped around a portion of the stock near the receiver.
In some embodiments, the main piece of the body 12 of the sling-attachment apparatus includes a hole, or loop, formed at the end opposite the quick-detach sling socket, as opposed to an opening which extends into the passageway within the body. In such an embodiment, the flexible member (e.g., 550 cord) may simply be looped through, or even tied to, the body using the hole.
In some embodiments, the flexible member may have ball ends attached (e.g., via welding) to the two ends of thereof. The ball ends may be used to perform the same function(s) as the stopper component (e.g., the crimp 44) described above (e.g., to prevent the flexible member from being pulled through the flexible member opening in the end of the body opposite the quick-detach sling socket) and may thus have a width (or diameter) that is greater than the width of the flexible member opening in the main piece of the body 12. In some embodiments, the flexible member may simply be a cord, such as 550 cord, with knots tied in the ends thereof (i.e., the knots functioning in a manner similar to the ball ends, or the stopper component).
Thus, in some embodiments, an apparatus for coupling an accessory to a firearm is provided. The apparatus includes a socket body. The socket body is made of a rigid material and has a first opening at a first end thereof, a second opening at a second end thereof, and a passageway extending therethrough that interconnects the first and second openings. The first opening and/or the first end of the socket body is configured to form a quick-detach sling socket.
In some embodiments, a flexible member is coupled to the socket body. The flexible member may be inserted through the second opening of the socket body such that a first portion of the flexible member is positioned within the passageway of the socket body and a second portion of the flexible member is positioned on the exterior of the socket body. A stopper component may be connected to the second portion of the flexible member. The stopper component may have a width that is greater than a width of the second opening.
In some embodiments, a compressible body is positioned within the passageway between the second end of the socket body and the stopper component. The compressible body may have an opening therethrough. The second portion of the flexible member may extend through the opening of the compressible body.
In some embodiments, at least on tactile indicator is formed (or positioned) on the socket body. The tactile indicators may be one or more o-rings, each of which may be positioned within a respective groove formed on the socket body.
In some embodiments, an apparatus for coupling an accessory to a firearm is provided. The apparatus includes a body having a first portion and a second portion. The first portion of the body has an opening formed thereon. The body further includes a cavity formed therein. The cavity is in fluid communication with the opening on the first portion of the body. The opening is configured to form a quick-detach sling socket. The body and the cavity are configured such that when a portion of a quick-detach sling swivel is inserted into the opening, the portion of the quick-detach sling swivel is substantially enclosed within the cavity formed within the body. A flexible member is coupled to the second portion of the body.
The second portion of the body may have a second opening formed therein. The flexible member may be at least partially inserted through the second opening. The flexible member may form a loop having a first end and a second end. The first end of the loop may be inserted through the second opening. The second opening may be in fluid communication with the cavity formed within the body. A stopper component may be connected to the first end of the loop and positioned within the cavity formed within the body. A width of the stopper component may be greater than a width of the second opening. The width of the stopper component may be less than a width of the opening on the first portion of the body. The body may be substantially cylindrical in shape. The first portion of the body may be a first end of the body, and the second portion of the body may be a second end of the body. The second end of the body may be opposite the first end of the body.
