DETAILED DESCRIPTION
(16) While the making and using of various embodiments of the present invention are discussed in detail below, it should be appreciated that the present invention provides many applicable inventive concepts that are embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention and do not delimit the scope of the invention.
(17) To facilitate the understanding of the embodiments described herein, a number of terms are defined below. The terms defined herein have meanings as commonly understood by a person of ordinary skill in the portions relevant to the present invention. Terms such as a, an, and the are not intended to refer to only a singular entity, but rather include the general class of which a specific example may be used for illustration. The terminology herein is used to describe specific embodiments of the invention, but their usage does not delimit the invention, except as set forth in the claims.
(18) Referring to
(19) As shown in
(20) Unlike traditional slings that use one or more typically thin, flat, leather or synthetic straps as the primary structure that supports the weight of a firearm, the sling of the present disclosure advantageously uses a cord having a generally rounded cross section as the primary structure that supports the weight of an attached firearm. As will be explained in more detail below with reference to an exemplar embodiment, the use of a cord having a substantially circular cross section permits a user to slide the secondary strap assembly 40 along the length of sling loop 20 and thereby customize the configuration and fit of the sling 10.
(21) The sling loop 20 is formed by arranging the elastic cord 22 into a closed loop, which in some embodiments, can be a static loop having the shape of an elongated teardrop. The loop 20 is at least large enough to receive a user's head so that the user can easily insert the user's head, and in some embodiments, the user's arm and shoulder, through the loop 20.
(22) In the embodiment exemplified in
(23) The sling loop 20 includes a lower strap assembly attachment portion 23 and an upper strap assembly attachment portion 24. The lower strap assembly attachment portion 23 includes the first and second end segments 25a, 25b of the cord 22 forming the lower narrow portion of the sling loop 20 shown in
(24) Referring now to
(25) As illustrated in
(26) The adjustable slide 46 has a well-known design that will be familiar to skilled artisans and is structurally similar to slide 50, except that the frame and central bar of adjustable slide 46 may not be rounded and the exterior of the frame includes outwardly extending tabs to facilitate movement of the slide by a user along the secondary strap 42 to which it is connected. The adjustable slide 46 can be formed from a metallic or plastic material, but in an embodiment is preferably formed from a resilient plastic to reduce the overall weight of the sling 10.
(27) The firearm attachment means 44 is a standard sling swivel 44 having a ring 44a around which a portion of the secondary strap 42 can be looped as shown in
(28) As best shown in
(29) The second loop 55 of the dual loop arrangement is an adjustable loop 55 formed around a section of elastic cord 22 at the upper strap assembly attachment portion 24 of sling loop 20. Specifically, adjustable loop 55 is formed around cord 22 by the two overlapping and aligned layers of strap 42 forming closed loop 48 and extending generally downwardly from central bar 52, as shown in
(30) Adjustable loop 55 can be tightened around and frictionally engaged with cord 22 to selectably retain secondary strap 42 in place on the sling loop 20 by holding slide 50 and pulling the distal end portion 41 of strap 42 away from adjustable loop 55. Adjustable loop 55 can also be tightened around cord 22 by holding a portion of strap 42 distal to slide 50, and applying longitudinal pressure to the sides of slide 50 to slide the slide along the longitudinal axis of strap 42 toward the sling loop 20. Adjustable loop 55 can be loosened around cord 22 to facilitate easier sliding of adjustable loop 55 along sling loop 20 by holding slide 50 and pulling the portion of proximal end portion 43 forming adjustable loop 55 back down through second slot 54. Strap 42 can be released from the sling loop 20 by withdrawing the distal end 45 of strap 42 from the slots 53, 54 of slide 50. In this way, the proximal end portion 43 of the secondary strap 42 is releasably attached to and in slidable frictional engagement with sling loop 20.
(31) This dual loop arrangement allows a user to quickly and easily change the position of the secondary strap 42 on the sling loop 20 to customize sling 10 to accommodate different carrying and firing positions by manually sliding the adjustable loop 55 along the longitudinal axis of the cord 22 forming sling loop 20 as indicated in
(32) Referring again to
(33) Referring now to
(34) As shown in
(35) The proximal end portion 33 of strap 32 can be secured to the lower attachment portion 23 of sling loop 20 by first placing the proximal end portion 33 adjacent and parallel to end segments 25a, 25b of elastic cord 22 forming lower portion 23 of sling loop 20. A first clamping means 28a can then be placed around end segments 25a, 25b and proximal end portion 33. The proximal end portion 33 can then be folded down over the first clamping means 28a toward the distal end 35 of the primary strap 32 so that the proximal end portion 33 wraps around the first clamping means 28a and aligns with end segments 25a, 25b. A second clamping means 28b can then be placed around end segments 25a, 25b and proximal end portion 33 below the first clamping means 28a. The first and second clamping means 28a, 28b can then be tightened or crimped to secure the proximal end portion 33 of the strap 32 to the end segments 25a, 25b of the elastic cord 22.
(36) In other embodiments, the primary strap 32 can be permanently attached to the lower strap assembly attachment portion 23 by any method or means that secures the primary strap assembly 30 to the lower attachment portion 23 and prevents the primary strap 32 from separating or pulling away from the sling loop 20 when the sling 10 is attached to and supporting the weight of a firearm. In preferred embodiments, it is intended that the primary strap 32 remain securely connected to the sling loop 22 to anchor the sling loop in a given orientation relative to an attached firearm. This enables the sling loop 20 to freely rotate around the portion of the user on which the sling 10 is worn as the firearm is moved around the user's body during use of the firearm or adjustment of the sling 10. However, in other embodiments, the primary strap assembly 30 can be releasably attached to the lower strap assembly attachment portion 23 of sling loop 20 in the same way that secondary strap assembly 40 is releasably attached to the upper strap assembly attachment portion 24 of sling loop 20.
(37) As shown in
(38) Once the primary strap assembly 30 is secured to the lower strap assembly attachment portion 23 as disclosed above, the heat shrink tubing 26 can be applied to the sling 10 by sliding the section of heat shrink tubing 26 over the distal end portion 31 of the primary strap 32 and onto the lower attachment portion 23 so that the heat shrink tubing 26 covers cord segments 25a, 25b, clamping means 28a, 28b, and proximal end 37. Once the heat shrink tubing 26 is in place, a heat source can be used to heat and thereby shrink fit the tubing 26 to the lower attachment portion 23.
(39) In some embodiments, a section of heat shrink tubing 26 can also be applied to secondary strap assembly 40 to sheath the portion of secondary strap 42 extending between adjustable loop 55 and ring 44a of firearm attachment means 44. However, sheathing secondary strap 42 in this way precludes use of adjustable slide 46, effectively making strap 42 non-adjustable, which may be preferable in some applications.
(40) In some embodiments, a label or logo tag 39 can be adhered or sewn to the proximal end portion 33 of primary strap 32 to display a logo, brand name, or other indicia. In the embodiment depicted in
(41) The firearm attachment means 34 is a standard sling swivel 34 having a ring 34a around which a portion of the primary strap 32 is looped as shown in
(42) As best shown in
(43) Referring now to
(44) When attached to a firearm as shown in
(45) Referring now to
(46) When attached to a firearm as shown in
(47) As explained above, the secondary strap assembly 40 can be detached from sling loop 20 to convert the sling 10 into a single-point configuration. In such configuration, the primary strap assembly 30 can easily be releasably attached to the buttstock of the rifle 70 or a single point sling attachment point 75 located at the rear of the receiver of the rifle 70.
