TECHNICAL FIELD
The techniques described herein are generally related to a sling mount stud in a firearm.
BACKGROUND
Generally, a firearm is a device that is designed to expel a projectile (e.g., a bullet) through the barrel of the firearm upon activation of an explosive (e.g., gunpowder within a casing of a cartridge that also holds the bullet). Firearms often include a trigger configured to actuate a firing pin to strike a fuse (e.g., a primer) of the cartridge to ignite the explosive, which causes the projectile(s) (e.g., including a bullet) to be expelled through the barrel of the firearm. Such interaction of the firing pin to the fuse is often controlled by depressing the trigger.
SUMMARY OF INVENTION
Aspects described herein relate to a mounting interface, and in particular to a firearm sling mount stud. Some embodiments relate to a stud that extends through a forearm of a firearm in a substantially perpendicular direction relative to a screw that attaches the forearm to a receiver of the firearm. The stud is prevented from unscrewing from the forearm by a screw sleeve that prevents rotation of the stud.
There have thus been outlined, rather broadly, the features of the disclosed subject matter in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the disclosed subject matter that will be described hereinafter and that will form the subject matter of the claims appended hereto. It is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.

DETAILED DESCRIPTION
The techniques described herein provides for securing a sling to a firearm with a sling mount stud. A sling can generally allow a firearm user to carry the firearm handsfree. The sling mount stud described herein may be secured within a forearm of the firearm to prevent rotation or other movement of the stud that may cause loosening of the stud over repeated use.
The inventors have appreciated deficiencies with conventional sling swivel studs and other sling mounts. In particular, the inventors have appreciated that various types of sling mounts that include screws can become unscrewed over time due to repeated use. One example of such a sling mount is screwed into the forearm. Another example of such a sling mount is screwed into a cap on the end of the forearm. Both of these approaches are susceptible to the sling mount becoming unscrewed over time (e.g., as the sling is used to swing the firearm over a user's shoulder for carrying the firearm).
Accordingly, the inventors recognized and appreciated the advantages of a sling mount stud according to embodiments described herein. For example, the inventors have appreciated that using a stud, rather than a screw, that is retained in the forearm without being able to rotate during use of the sling to hold the firearm can prevent the stud from loosening from the firearm.
In the following description, numerous specific details are set forth regarding the systems and methods of the disclosed subject matter and the environment in which such systems and methods may operate, etc., in order to provide a thorough understanding of the disclosed subject matter. In addition, it will be understood that the examples provided below are exemplary, and that it is contemplated that there are other systems and methods that are within the scope of the disclosed subject matter.
FIG. 1 is a perspective diagram of an exemplary lever-action firearm 100, according to some embodiments. On one end of the firearm 100 is a barrel 102 through which a projectile (e.g., a bullet) is expelled from the firearm 100. The opposite end of the firearm 100 is referred to as the butt 104 of the firearm 100. The exemplary firearm 100 is shown to include a magazine 103 that can be loaded into (and released from) the firearm 100. The magazine 103 may hold a set (e.g., five, ten, fifteen, twenty, thirty, etc.) of cartridges (not shown) for use with the firearm 100. Each cartridge may include a casing (or shell, such as in the case of a shotgun), a projectile(s) disposed at a proximal end of the casing (e.g., bullet, shot, slug, etc.), a fuse disposed at a distal end of the casing, and an explosive disposed within a portion of the casing between the fuse and the projectile. A cartridge from the magazine 103 may be received into a chamber 108 (not visible) disposed adjacent to the barrel 102.
The exemplary lever-action firearm 100 shown in FIG. 1 includes a lever 105 that, when actuated by a user, loads a cartridge into the chamber 108 and/or unloads a cartridge from the chamber 108. An arrow indicates the direction of actuation of the lever 105, down and toward the barrel 102. The firearm 100 also includes a firing pin assembly and/or firing pin (not shown) that is mechanically actuatable by the trigger 107, such that upon actuation of the trigger 107, the firing pin is configured to contact the fuse of the cartridge loaded into the chamber 108 to ignite the explosive and to cause the projectile(s) to be expelled through the barrel 102 of the firearm 100. In alternate embodiments, the actuator 106 that initiates side ejection of the casing need not be a lever 105 and the firearm may be a bolt action firearm or a pump action firearm, for example. In further alternate embodiments, the firearm may involve automatic actuation. The exemplary illustration is not intended to limit the type of firearm that may employ the sling mounting interface detailed herein.
A forestock of the firearm 100, referred to as a forearm 110, is shown in FIG. 1. The forearm 110 may attach to a receiver 115 of the firearm 100. FIG. I also shows a sling 120 that extends from the forearm 110 toward the butt 104 of the firearm 110. The sling 120 may be used to swing the firearm 100 over the shoulder of a person carrying the firearm 100 (to rest on the carrier's back) for transport and to subsequently swing the firearm 100 to the front of the carrier (e.g., for use or storage). While using the firearm 100, the forearm 110 may be held to aim and steady the firearm 100. The forearm 110 may be solid wood or a synthetic material with boreholes 310, 315 formed within for a sling mounting interface and other components, as further detailed with reference to FIGS. 2-4.
FIG. 2 shows aspects of an exemplary firearm 100 according to some embodiments. As shown, the forearm 110 extends parallel to the barrel 102 of the firearm 100 and is below the barrel 102 according to the orientation indicted in FIG. 1. The forearm 110 includes a trough 250 that goes around the barrel 102 partially. However, the barrel 102 may not contact the trough 250 such that there is a gap 255 between the forearm 110 and the barrel 102. The forearm 110 is shown as transparent to reveal the components that are disposed in boreholes within the forearm 110. One of those components, a sling mount stud 210, is shown with an opening 215 protruding from the forearm 110. A cross-sectional shape of the sling mount stud 210 may be circular, as in the exemplary illustration, but is not limited to any particular shape or to a uniform shape or dimensions along the length of the sling mount stud 210.
A sling 120 may be attached to the firearm 100 via the opening 215. The opening 215 is an exemplary sling attachment portion 216 of the sling mount stud 210. In alternate embodiments, the sling attachment portion 216 may be or may include a tab, ring, clip, or other detachable interface. The sling mount stud 210 is substantially perpendicular to a screw 220 that attaches the forearm 110 to the receiver 115, which is to the left of the forearm 110 according to the orientation shown in FIG. 2.
The screw 220 may be inserted and tightened via a screw opening 225 in the forearm 110, as indicated. The screw opening 225 is defined by a screw sleeve 230. That is, the screw sleeve 230 may concentrically surround the screw 220. The screw opening 225 and screw sleeve 230 are closer to the front of the firearm 100, while a forearm stud 240 is closer to the back the firearm 100 according to the indicated orientation in FIG. 2. The screw 220 couples the forearm 110 to the receiver 115 through the forearm stud 240. According to the exemplary embodiment shown in FIG. 2, the forearm stud interface 245 (e.g., hexagonal cap on the forearm stud 240) may be used to screw the forearm stud 240 to the receiver 115 and the screw 220 may be screwed into the forearm stud interface 245. In alternate embodiments, the screw 200 may extend into the receiver 115. The screw 220 goes through the sling mount stud 210, as shown in FIG. 2. As such, the screw 220 prevents movement of the sling mount stud 210 up and down according to the orientation indicated in the figures and prevents rotation of the sling mount stud 210. Thus, the sling mount stud 210 cannot come out of the forearm 110. In addition, as is clearer in FIG. 3, the screw sleeve 230 presses against the sling mount stud 210 to further hold the sling mount stud 210 in place and prevent rotation.
FIG. 3 is a perspective diagram of an exemplary firearm 100 exposing components within the forearm 110 according to some embodiments. Specifically, half of the forearm 110 and barrel 102 are removed to expose the components formed in boreholes 310, 315 within the forearm 110. Boreholes 310 accommodate the screw 210, screw sleeve 230, and forearm stud 240, while a substantially perpendicular borehole 315 accommodates the sling mount stud 220. According to the exemplary embodiment shown in FIG. 3, a receiver interface 320 of the forearm stud 240 affixes the forearm stud 240 to the receiver 115 based on tightening of the forearm stud interface 245, and the screw 220 extending along the forearm 110 is affixed to the forearm stud interface 245 based on tightening the screw 220 at the screw access 225.
The sling mount stud 210 is held within the borehole 315. Since the screw 220, also held within a borehole 310, goes through the sling mount stud 220, the sling mount stud 220 cannot move up or down or rotate. According to the exemplary embodiment shown in FIG. 3, the screw sleeve 230 is tightened against the sling mount stud 220, further preventing rotation of the sling mount stud 210 that may cause the sling mount stud 220 to loosen over time. In alternate embodiments, the screw sleeve 230 may be eliminated, and a head of the screw 220 may be tightened against the sling mount stud 210.
FIG. 4 is a cross-sectional view through the forearm 110 and barrel 102 of an exemplary firearm 100 according to some embodiments. Specifically, the cross section shows a bisection of the barrel 102 and forearm 110 such that the borehole 310 accommodating the screw 220 is exposed and half of the trough 250 is shown. As FIG. 4 shows, the sling mount stud 210 is disposed in a borehole 315 within the forearm 110 that is substantially perpendicular to the borehole 310. That is, the borehole 315 and the sling mount stud 210 generally extend between up and down, while the borehole 310 and the screw 220 within the borehole 310 generally extend between front and back according to the orientation indicated. FIG. 4 also shows that the screw 220 goes through the sling mount stud 220, and the screw sleeve 230, which is in front of the sling mount stud 210 according to the labelled orientation, is pressed against the sling mount stud 210. Thus, as noted with reference to FIG. 3, the screw 220 and the optional screw sleeve 230 prevent rotation or any movement of the sling mount stud 210.
FIGS. 5A and 5B show perspective exposed views of exemplary firearms 100 with different types of forearm studs 240 that include the sling mount stud 210 according to some embodiments. The forearm 110 and barrel 102 are eliminated in both figures to expose the components within the forearm 110. FIG. 5A shows an exemplary firearm 100 with a forearm stud 240 that includes a forearm stud interface 245 and a receiver interface 320, as discussed with reference to FIG. 3. A substantial portion of the exemplary forearm stud 240 between the forearm stud interface 245 and the receiver interface 320 is shown to be cylindrical in shape. FIG. 5B shows an exemplary firearm 100 with a forearm stud 240 that has a tapered cross-sectional width as it extends along the forearm 110. As a comparison of FIGS. 5A and 5B indicates, the same sling mount stud 210 may be used with the different forearm stud designs. Generally, the sling mount stud 210 is not limited to use in a firearm 100 with a particular forearm stud 240, receiver 115, or any other aspect.
FIG. 6 shows a side view of aspects of an exemplary firearm 100 according to some embodiments. The forearm 110 is removed to show the components that are disposed in boreholes 310, 315 within the forearm 110. The sling mount stud 210 is shown substantially perpendicular to the screw 220, which extends into the forearm stud interface 245 of the forearm stud 240 to couple the forearm 110 to the receiver 115. While the receiver 115 is shown attached to the forearm stud 240 at its receiver interface 320, the screw 220 may extend into the receiver 115 in alternate embodiments. The sling attachment portion 216 of the sling mount stud 210 is shown as an opening 215 in the exemplary illustration in FIG. 6 but could be another type of sling attachment in alternate embodiments. The screw sleeve 230 presses into the sling mount stud 210 on one side (e.g., front side according to the labeled orientation). The screw 220 prevents both up and down movement of the sling mount stud 210 and rotation. The screw sleeve 230 additionally prevents rotation of the sling mount stud 210. Thus, the sling mount stud 210 is prevented from unscrewing or otherwise coming out of the forearm 110 according to the relative arrangement of the forearm components according to some embodiments.
FIGS. 7A and 7B show different views of an exemplary sling mount stud 210 according to some embodiments. FIG. 7A is a view of an exemplary sling mount stud 210 that shows the exemplary sling attachment portion 216 to be an opening 215. As FIG. 7A illustrates, if the view is regarded as a front view, the sling mount stud 210 may have indentations 710 in one or both sides. By providing a flat interface, the indentation 710 may facilitate a tighter coupling with the screw sleeve 230 or a head of the screw 220 used to prevent rotation of the sling mount stud 210. FIG. 7B is a perspective view of the exemplary sling mount stud 210 that shows the hole 720 that the screw 220 may extend through to secure the sling mount stud 210 within the forearm 110.
It should be appreciated that while FIGS. 1-7B show exemplary configurations of a sling mount stud, this is intended to be for illustrative purposes and not to be limiting. It should be appreciated that various other mechanical configurations and/or components can be used to achieve the techniques described herein.
