Description
- This application claims the benefit of U.S. Provisional Application No. 60/627,340, filed Nov. 12, 2005, the entire contents of which are hereby incorporated by reference as if presented herein.
- 1. Technical Field
- The present invention generally relates to a connector for attaching a carrying strap or sling to an object to be carried, and in particular to a swivel attachment for attaching a sling to a firearm to facilitate carrying of the firearm.
- 2. Related Art
- The ability to carry bulky or heavy objects such as firearms has long been a need for persons such as hunters, sportsmen and soldiers. Typically, firearms include a sling that is attached adjacent to the barrel of the firearm and at another point, typically along the stock of the firearm. The sling allows the user to carry the firearm on his shoulder with his hands free.
- A variety of devices have been used for attaching a sling to a firearm, the most common device being a sling swivel. Examples of swing swivels are shown in U.S. Pat. Nos. 156,614 and 575,164. More recently, attention has been directed to providing quick detachable sling swivels, such as the sling swivels shown in U.S. Pat. Nos. 5,501,025, 5,718,075 and 6,536,154. A problem exists with conventional sling swivel devices, however, in that they may be typically overly complex, expensive to manufacture, and difficult and/or time consuming to use.
- According to a first embodiment of the present invention, a swivel connector comprises a wound body formed from a strip of flexible material having a first end and a second end. The swivel connector can have a pivot section for engagement with a mounting structure such as a firearm swivel stud, and a base section for engaging a strap or sling. The swivel connector can have a generally trapezoidal shape when viewed from the front, with the base section being wider than the pivot section.
- According to the first embodiment of the invention, the geometry of the swivel connector inhibits the swivel connector from sliding through and/or spinning about the mounting structure. This feature inhibits the swivel connector from unwinding from and thereby disconnecting from the mounting structure.
- The swivel connector can include relatively generous corner bend radii at its lower corners that transition to relatively tight corner bend radii at its upper corners. The relative sizes of the upper and lower corner bend radii allow the sling to lay flat against a firearm during shooting. When the firearm is being carried, the geometry of the swivel connector causes the connector to lay flat against the back or shoulder of the user carrying the firearm.
- According to the first embodiment, the swivel connector may be of a relatively small size, which may enable manufacture at a reduced cost. The swivel connector may also be constructed from a single piece of material, such as wire or other strip materials, which may reduce the complexity of manufacture of the swivel connector and render the swivel connector easier to use.
- Other aspects, features, and details of embodiments of the present invention can be more completely understood by reference to the following detailed description of preferred embodiments, taken in conjunction with the drawings figures and from the appended claims.
- According to common practice, the various features of the drawings discussed below are not necessarily drawn to scale. Dimensions of various features and elements in the drawings may be expanded or reduced to more clearly illustrate the embodiments of the invention.
-
FIG. 1 is a perspective view of a swivel connector according to a first embodiment of the invention. -
FIG. 2 is front elevational view of the swivel connector. -
FIG. 3 is a side elevational view of the swivel connector. -
FIG. 4 is a sectional view taken on line 4-4 inFIG. 2 . -
FIG. 5 a perspective view of the swivel connector attached to a sling swivel stud mounting structure. - The invention as exemplified by the present embodiments discussed below is generally directed to a swivel connector for the attachment of a sling, strap or other carrying device to an article to be carried. The article to be carried can be, for example, a firearm such as a shotgun, rifle, or other long guns, or even some types of handguns as desired. In the exemplary embodiments discussed below, the swivel connector is formed as a wound “split ring” to facilitate connection of a sling or other carrying strap to the swivel connector, as well as for attachment of the swivel connector to the article to be carried.

FIG. 1 is a perspective view of aswivel connector 10 according to a first embodiment of the invention. Theswivel connector 10 includes a body orstrip 15 formed from a continuously wound loop or strip of material having afirst end 12 and asecond end 14. Thebody 15 is wrapped or wound into a double thickness of overlapped strip material, except at asection 16. Thesection 16 may be disposed at an intermediate portion of thebase 30 and provides an entry or access point for mounting the swivel connector to swivel mounting studs, for example, or other support devices on an article to be carried. - Referring also to
FIG. 2 , theswivel connector 10 is generally divided into apivot section 20 and abase section 30. Thepivot section 20 is connected to afirst side section 42 by a firstupper corner 22, and to asecond side section 44 by a secondupper corner 24. Thefirst side section 42 is connected to thebase section 30 by a firstlower corner 32, and thesecond side section 44 is connected to thebase section 30 by a secondlower corner 34. - When viewed from the front, as shown in
FIG. 2 , thepivot section 20 can be, for example, straight or substantially straight. Thepivot section 20 serves as the primary point of attachment of theconnector 10 to a mounting structure on an article to be carried, such as, for example, a sling swivel stud of a firearm. Thebase section 30 may also be straight or substantially straight, and serves as the primary point of attachment to a carrying device such as, for example, a sling of a firearm, or other devices such as carrying straps for cameras, etc. The first andsecond side sections swivel connector 10 may also be, for example, straight or substantially straight, and generally taper inwardly from thebase 30 toward thepivot section 20. - Referring again to
FIG. 2 , the first and secondlower corners swivel connector 10 define an interior width W1 of the swivel connector. Thebase 30 may have an interior width W3 that is wider than an interior width W2 of thepivot section 20. In one embodiment, the interior width W2 can be, for example, less than about 80% of the interior width W3 of thebase 30. In another embodiment, the interior width W2 is less than about ⅔ of the interior width W3. Theswivel connector 10 has an interior height H extending between thepivot section 20 and thebase section 30. The first and secondupper corners lower corners lower corners swivel connector 10 can have relatively larger corner bend radii or curvatures than those of theupper corners FIG. 2 , theswivel connector 10 has a generally trapezoidal shape with rounded or curved corners, and may be symmetric about a line bisecting thepivot section 20 and thebase 30. -
FIG. 3 is a side elevational view of theswivel connector 10, andFIG. 4 is a sectional view of theswivel connector 10 taken on line 4-4 inFIG. 2 . Referring toFIG. 3 , the thickness of the double wound strip of material forming thebody 15 is indicated by T1. Referring toFIG. 4 , the thickness of an individual winding of thematerial strip 15 is indicated by T2, and the height of thematerial strip 15 is indicated by HS. The exterior of thematerial strip 15 may have, for example, a wholly or partially curvedouter profile 60, and a generally flat or planarinner profile 62 where the opposed sections of thestrip 15 face one another. -
FIG. 5 is a perspective view of theswivel connector 10 attached to an exemplaryfirearm swivel stud 100 mounting structure. Theswivel stud 100 may be, for example, conventional in construction and is typical of known swivel studs used to connect slings to rifles, shotguns, and other firearms. Such a swivel stud may also be found on firearms such as machine pistols and/or certain conventional autoloading or single action pistols and handguns, for example. Typically, one such swivel stud is mounted at or near the barrel of a firearm, and another swivel stud is mounted at or near the firearm stock. When a sling is connected to each end of the firearm at the swivel studs by aswivel connector 10, the firearm can be carried in a hands-free mode by the firearm sling. - As shown in
FIG. 5 , theswivel connector 10 is mounted in a cylindrical through-hole aperture 102 that extends through theswivel stud 100. Theswivel connector 10 may be attached to theswivel stud 100 by prying or otherwise separating the double wound portion of thestrip 15 open at thelocation 70. Thefirst end 12 of thematerial strip 15 may then be pushed into the through-hole aperture 102 and theswivel connector 10 rotated through theaperture 102 until it passes thesecond end 14 to reach the position shown inFIG. 5 . The geometry of theswivel connector 10 is selected so that thepivot section 20 is pivotably received in and tends to remain engaged with the through-hole aperture 102. - The geometry of the
base 30 of theswivel connector 10 is selected to receive and remain engaged with a sling, strap, or other carrying device. For example, a rifle sling (not shown) having a loop at one or both ends can be attached to theswivel connector 10 by separating thedouble wound strip 15 at thelocation 70, inserting the sling into the strip at thelocation 70, and rotating theswivel connector 10 until it passes thesecond end 14 of thedouble wound strip 15. In one method of attachment, both a sling and a swivel stud may be inserted into thedouble wound strip 15 at thelocation 70 at the same time, so that when theswivel connector 10 is rotated, both the swivel stud and the sling are secured to theswivel connector 10. - According to the present invention, both the first and second ends 12, 14 of the
material strip 15 may be located at or adjacent to an intermediate portion of thebase 30. Accordingly, a mounting structure and/or sling may alternatively be inserted into thedouble wound strip 15 at thesecond end 14 of the strip. - A sling or strap may alternatively be attached to the
swivel connector 10 by inserting a free end of the sling through the opening in the center of theconnector 10, and then attaching the free end of the sling to an intermediate section of the sling to form a closed loop around thebase 30. - According to the present invention, as shown in
FIG. 5 , the engagement of thepivot section 20 with the through-hole aperture 102 in thefirearm swivel stud 100 allows theswivel connector 10 to pivot longitudinally (i.e., thebase section 30 may swing forward and backward) with respect to the firearm. At the same time, twisting rotational movement of theswivel connector 10 about theswivel stud 100 is inhibited. Referring toFIGS. 2 and 5 , the relatively tight radii or curvatures R1 of theupper corners pivot section 20 further inhibit theswivel connector 10 from sliding through (i.e., moving longitudinally or lengthwise through the through-hole aperture 102) or otherwise spinning about theswivel stud 100. This characteristic inhibits theconnector 10 from unthreading from theswivel stud 100, and therefore maintains the engagement of theswivel stud 100 with thepivot section 20. - According to the present invention, the relatively generous bend radii of the
lower corners upper corners - Other mounting structures besides swivel studs may be used in conjunction with the
swivel connector 100. In general, any mounting structure having a through-hole aperture sized to receive theswivel connector 10 is suitable. - The
swivel connector 10 has the form of a split ring to facilitate connection or attachment of the sling thereto, as well as attachment of the sling swivel to the connector stud of a firearm. In this specification, a “split ring” is any strip of flexible or relatively flexible piece of material wound into a closed loop having at least a double winding of the strip along a majority of the length of material. The present embodiments are discussed in terms of a split ring having a double winding. Three, four, or more windings, however, can be incorporated into a split ring swivel connector in accordance with the present invention. - The
swivel connector 10 may be made from, for example, a single, continuous piece of flexible material having substantially or wholly consistent material properties throughout the piece of material forming the connector. Suitable materials of construction include materials such as, for example, plastics, ceramic composites or other synthetic materials selected to be durable, flexible, and light-weight. Materials which are easily moldable or machinable may reduce manufacturing costs. Other types of lightweight, durable and flexible materials, including some metals such as aluminum, steel, and metal alloys, can also be used. Theswivel connector 10 may be constructed from wholly or partially elastic materials. - The
swivel connector 10 of the present invention further can include a corrosion resistant coating, in addition to being formed from corrosion resistant materials such as plastics, ceramic composites, synthetics or metal materials such as aluminum or stainless steel. The relatively small size of theswivel connector 10 and its one-piece of material enable relatively simple and low cost manufacture. - A
swivel connector 10 as illustrated inFIGS. 1-5 is constructed from steel. The interior width W1 of theswivel connector 10 is 1.11 inches, the interior width W2 of thepivot section 20 is 5/16 inches, and the interior width W3 of thebase 30 is 0.56 inches. The interior height H of theswivel connector 10 is ⅞ inches, the interior radii R1 of theupper corners lower corners double wound strip 15 is 0.12 inches, the thickness T2 of a single winding of thematerial strip 15 is 0.06 inches, and its height HS is 0.08 inches. Theswivel connector 10 is formed by mandrel winding followed by coining in a die to create outside radii on the steel wire. Theswivel connector 10 is coated with a corrosion resistant black zinc finish. - In this specification, the term “wound” does not necessarily indicate a structure formed by a winding process involving an actual winding step. For example, a swivel connector according to the present invention can be formed from a molding process that results in multiple windings of a strip of molded material.
- The above embodiments illustrate a single split ring as forming the
swivel connector 10. In alternative embodiments, a pair of split rings also can be used. The pair of split rings can be releasably attached together to provide separate attachment and release mechanisms for the sling and the stud connector of the firearm. - The foregoing description of the invention illustrates and describes the present invention. Additionally, the disclosure shows and describes only selected embodiments of the invention, but it is to be understood that the invention is capable of use in various other combinations, modifications, and environments and is capable of changes or modifications within the scope of the inventive concept as expressed herein, commensurate with the above teachings, and/or within the skill or knowledge of the relevant art.
