DESCRIPTION OF THE CURRENT EMBODIMENT

(13) An embodiment of the sling attachment device of the present invention is shown and generally designated by the reference numeral 10.

(14) FIG. 1 illustrates the improved sling attachment device 10 of the present invention. More particularly, FIG. 1 shows two sling attachment devices in use attaching a sling strap 50 to a rifle 70. Each sling attachment device has a body 12 with a sling strap slot 16. Each opposed end 52, 54 of the sling strap is inserted through a sling strap slot and is releasably secured to the sling strap by a buckle 56, 58. Each sling attachment device also has a tether in the form of a cable loop 14 having a secured end 32 and a free end 34. When the cable loop is in the open position, the free end can be inserted through an eyelet 76, 78 located at the front 72 and rear 74 of the rifle. The free ends are then releasably attached to the body in the closed position in a manner that will be described in more detail in the description of FIGS. 2-4. Because the cable loop can be positioned in both the open and closed positions while an end of the sling strap is attached to the body, the sling strap can be easily and quickly removed from the rifle without first detaching the sling strap from the body.

(15) FIGS. 2-8 illustrate the improved sling attachment device 10 of the present invention. More particularly, FIG. 2 shows a sling attachment device with the cable loop 14 in the open position. The body 12 is generally trapezoidal with a top 46, a bottom 48, and two wide slots (sling strap slot 16 and cable slot 26) at the front 38 and rear 40. The wide slots are separated by a bar 20. One end 54 of the sling strap 50 can be threaded through the sling strap slot 16 at the wider rear of the body and releasably secured to the sling strap using buckle 58.

(16) At the narrower front end 38 of the body 12 there are two small apertures 22, 24 that communicate with the cable slot 26. The bar 20 has a small aperture 42 that communicates with the sling strap slot 16 and the cable slot 26 and is axially registered with the aperture 22. Aperture 22 has the cable loop 14 running through it with the secured end 32 of the cable also passing through aperture 42. The secured end of the cable is permanently attached to the bar because it is enlarged to such an extent that the secured end cannot be withdrawn from aperture 42.

(17) The free end 34 of the cable loop 14 has a ball shank 36 attached to it to widen the free end of the cable loop. The aperture 24 is sized to permit free passage of the free end of the cable. The bar 20 defines a ball slot 28 and ball socket 30 that are axially registered with the aperture 24. The ball slot does not completely penetrate the bar, and the ball socket protrudes rearwardly from the bar and closely receives but does not completely encircle the ball shank.

(18) The free end 34 of the cable loop 14 is made to run through an eyelet 76, 78, loop, slot, or any other opening the free end can fit through on a firearm or anything else a user may wish to attach a sling strap to. As is shown in FIGS. 3 and 4, once the free end is inserted through an eyelet or other opening, the ball shank is pushed through the aperture 24 in the front end 38 of the body 12, up over the ball slot 28 and ball socket 30, and then pulled back to engage the ball shank in the ball socket and ball slot. This action places the cable loop in the closed position where the cable loop is secure and cannot come undone unless the ball shank is pushed up to disengage the ball shank from the ball socket and ball slot. The sling attachment device 10 is now securely attaching the sling strap 50 to the rifle 70.

(19) In the current embodiment, the ball slot is a channel that is wider than the cable loop and narrower than the ball shank. The ball socket is an enlarged portion adapted to closely receive the ball shank. The aperture 24 receives an intermediate portion 44 of the cable loop when the free end of the cable loop is received in the ball socket and ball slot such that lateral displacement of the cable loop does not displace the cable loop from the ball socket and ball slot. The body 12 is a planar member having a rear 40 first edge, and the cable loop is attached to the body at an attachment location defined by aperture 42 to extend in an opposed direction from the first edge and perpendicular to the bar. The ball slot and ball socket form a receptacle that is adjacent to the attachment location.

(20) In the current embodiment, the body 12 is CNC machined from a 6061-T6 aluminum billet before being tumbled and bead-blasted to provide a non-reflective surface. The body is hard-coat anodized before the flexible stainless steel aircraft-grade cable loop 14 with resilient nylon coating is installed with the metal ball shank 36 on the free end 34.

(21) FIGS. 9-11 illustrate an alternative embodiment of the improved sling attachment device 100 of the present invention. More particularly, FIG. 9 shows the sling attachment device in the released position, and FIGS. 10 and 11 show the sling attachment device in the secured position. The body 112 is generally trapezoidal with a top 146, a bottom 148, and two wide slots (sling strap slot 116 and cable slot 126) at the front 138 and rear 140. The wide slots are separated by a rear bar 120, which includes an upwardly and rearwardly extending hook 128 with catch 130. A front bar 142 extends across and above the cable slot. One end 54 of a sling strap 50 can be threaded through the sling strap slot 116 at the wider rear of the body and releasably secured to the sling strap using buckle 58.

(22) At the narrower front end 138 of the body 112 there are two small apertures 122, 124 that communicate with the cable slot 126. One end 132 of the cable loop 114 is permanently secured to the body 112 within aperture 122. An opposed end 134 of the cable loop runs through aperture 124. Cable loop end 134 has a ball shank 136 attached to it to widen that end of the cable loop. Cable loop end 134 is permanently attached to the front end 138 of the body because it is enlarged to such an extent by the ball shank that end 134 cannot be withdrawn from aperture 124.

(23) The cable loop 114 is made to run through an eyelet 76, 78, loop, slot, or any other opening the cable loop can fit through on a firearm or anything else a user may wish to attach a sling strap to. Alternatively, the cable loop can be run around the barrel or butt stock of a firearm. As is shown in FIG. 8, once the cable loop is inserted through an eyelet or other opening, the cable loop is pushed back under the front bar 142 on the body 112 and up the slanted side of the raised hook 128 where the cable loop snaps over the catch 130, which is a tooth-like protrusion.

(24) The protrusion holds the cable loop securely, and the front bar ensures lateral displacement of the cable loop does not displace the cable loop from the hook and catch. This action places the cable loop in the secured position where the cable loop is secure and cannot come undone unless the cable loop is pulled rearwardly and subsequently pushed up to disengage the cable loop from the hook and catch. The sling attachment device 100 is now securely attaching the sling strap 50 to the rifle 70.

(25) In the current embodiment, the body 112 is CNC machined from a 6061-T6 aluminum billet before being tumbled and bead-blasted to provide a non-reflective surface. The body is hard-coat anodized before the flexible nylon-coated stainless steel aircraft-grade cable loop 114 is installed with the metal ball shank 136 on the end 134.

(26) While current embodiments of a sling attachment device have been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. For example, the sling attachment device disclosed is also suitable for civilian hunting applications in addition to the disclosed military and law enforcement applications. In addition, although rifles have been disclosed, the sling attachment device is also suitable for use with shotguns, light and medium machine guns, and other firearms. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

(27) Therefore, the foregoing is considered as illustrative only of the principles of the invention.

(28) Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
