DETAILED DESCRIPTION

(6) Referring now to the drawings, FIG. 1 illustrates an adjustable lanyard 100. Lanyard 100 includes multiple attachment points, including at least a first attachment loop 102 and a second attachment loop 104. A central portion 106 is disposed between the first attachment loop 102 and the second attachment loop 104. For example, each of the first attachment loop 102 and the second attachment loop 104 are coupled to the central portion 106. In an embodiment, each of the first attachment loop 102, the second attachment loop 104, and the central portion 106, are formed by a single piece of material, such as a single strand of rope or cable. For example, the single strand of rope is one of ultra-high molecular weight polyethylene and high modulus polyethylene. Other related rope materials are, likewise, contemplated herein.

(7) In an embodiment, the first attachment loop 102, the second attachment loop 104, and the central portion 106 are comprised of an abrasion resistant rope. In a preferred embodiment, the first attachment loop 102, the second attachment loop 104, and the central portion 106 are comprised of a 6 mm diameter Kevlar rope. It should be appreciated, however, that additional or alternative materials and dimensions are contemplated herein.

(8) It should be appreciated that the lanyard 100 is adjustable. In this sense, at least one of the attachment loops 102, 104 is adjustable. For example, as illustrated in FIG. 1, the first attachment loop 102 has a fixed diameter; by comparison, the second attachment loop 104 has an adjustable diameter. Specifically, adjustment feature 108 is configured to translate along central portion 106 to increase or decrease the size or diameter of attachment loop 104. Because second attachment loop 104 has an adjustable diameter, the overall length of lanyard 100 is adjustable. For example, increasing the size of second attachment loop 104 (e.g., by translating adjustment feature 108 to the right as illustrated in FIG. 1) decreases the overall length of lanyard 100; decreasing the size of second attachment loop 104 (e.g., by translating adjustment feature 108 to the left as illustrated in FIG. 1) increases the overall length of lanyard 100. In an embodiment, the maximum length of lanyard 100 is 30 inches. It should be appreciated that, in an alternative embodiment, the first attachment loop 102 has the adjustable diameter and the second attachment loop 104 has the fixed diameter (e.g., implementing adjustment feature 108 with first attachment loop 102). Furthermore, in another alternative embodiment, both of the first attachment loop 102 and the second attachment loop 104 have adjustable diameters (e.g., implementing one adjustment feature 108 for each of first attachment loop 102 and second attachment loop 104).

(9) Continuing on with the embodiment illustrated by FIG. 1, the second attachment loop 104 terminates at an adjustment feature 108. For example, a terminal end of second attachment loop 104 may include the adjustment feature 108. Adjustment feature 108 is coupled to central portion 106 of lanyard 100. In an embodiment, adjustment feature 108 is a rope or cable, wrapped around a segment of central portion 106.

(10) Adjustment feature 108 is generally configured to be coupled to central portion 106, such that adjustment feature 108 may be selectively fixed (e.g., unable to slide relative to central portion 106) and unfixed (e.g., capable of sliding relative to central portion 106). In an embodiment, adjustment feature 108 is a rope having a diameter that is smaller than a diameter of rope associated with the central portion 106. In a related embodiment, adjustment feature 106 is a rope having a diameter that is smaller than the diameter of rope associated with each of the first attachment loop 102, the second attachment loop 104, and the central portion 106.

(11) As illustrated by FIGS. 2 and 3, in an embodiment, adjustment feature 108 is a Prusik knot or other friction hitch. In a particular example embodiment, adjustment feature 108 implements a Prusik knot with a girth hitch. It should be appreciated that other similar knots and hitches are contemplated herein. In an embodiment, second attachment loop 104 and adjustment feature 108 are comprised of the same strand of rope; in this particular embodiment, the diameter of second attachment loop 104 is reduced at its terminal end and the portion of rope with the reduced diameter constitutes adjustment feature 108. In a different embodiment, second loop 104 terminates at an end of rope; adjustment feature 108 extends from the terminal end of second loop 104, as a separate rope having a smaller cross-sectional diameter than that of the second loop 104.

(12) In an embodiment, lanyard 100 includes a bull ring 118, disposed adjacent to adjustment feature 108. For example, bull ring 118 may be a piece of crimped metal. In an embodiment, bull ring 118 is configured to fix the total amount of rope associated with adjustment feature 108, to prevent adjustment feature 108 from becoming undesirably loose or detached from central portion 106.

(13) Returning now to FIG. 1, lanyard 100 further includes first wrap 110 and second wrap 112. For example, first wrap 110 is configured to cover any stitching associated with first attachment loop 102, given first attachment loop 102 has a fixed diameter. In an embodiment, first wrap 110 is a heat-shrink wrap. In an embodiment, two segments of first attachment loop 102 are sewn together underneath first wrap 110; in a related embodiment, two segments of first attachment loop 102 are sewn together with first wrap 110, such that first wrap serves as a barrier or scaffold. For example, when stitched together, the two segments of first attachment loop 102 have a 3,000 lb. strength rating at the stitching. In a different embodiment, two segments of first attachment loop are spliced together, underneath first wrap 110.

(14) Similarly, for example, second wrap 112 is configured to cover the terminal end of second attachment loop 104. Second wrap 112 may additionally be configured to retain a portion of adjustment feature 108, such as excess rope or cable that may exist when first attachment loop 104 is reduced to a smaller diameter. For example, a terminal end of adjustment feature 108 may slide within second wrap 112. In an embodiment, second wrap 112 is a heat-shrink wrap. In an embodiment, second attachment loop 104 terminates at second wrap 112 and adjustment feature 108 extends from second wrap. In a different embodiment, adjustment feature 108 may be coupled to a terminal end of the second attachment loop 104 (e.g., via another loop, spliced at the terminal end of second attachment loop 104). In a related embodiment, adjustment feature 108 is a hollow block core-less rope with a hitch-end (e.g., for coupling with a segment of central portion 106) and a looped-end (e.g., for coupling with the terminal end of second attachment loop 104).

(15) As noted previously, adjustable lanyards, such as lanyard 100, afford the user with an additional degree of control and customization with respect to attaching various equipment, personnel, and the like. For example, in a use-case, lanyard 100 is attached to a military vehicle, helicopter or other mode of transportation (referred to herein generally as vehicle). More particularly, the first attachment loop 102 is fixedly attached to the military vehicle. Necessary equipment is attached to the second attachment loop 104; because lanyard 100 is adjustable via adjustment feature 108, distance between the necessary equipment and the attachment point on the vehicle is controllable by the user. It should be appreciated that the second attachment loop 104 could be fixedly attached to the vehicle, such that equipment is attached to the first attachment loop 102. Alternatively, both of the first attachment loop 102 and the second attachment loop 104 could be fixedly attached to the military vehicle. In this embodiment, lanyard 100 operates as an adjustable strap for holding equipment to the military vehicle.

(16) It should be appreciated that lanyard 100 may include additional hardware for attaching purposes. For example, with reference to FIG. 4, lanyard 100 may include a first shackle 114 coupled to first attachment loop 102 and a second shackle 116 coupled to second attachment loop 104. In a particular embodiment, first shackle 114 is a snap shackle. For example, first shackle 114 has a 4,000 lb. strength rating. In a particular embodiment, second shackle 116 is a TUDOR™ snap hook. For example, second shackle 116 has a 7,300 lb. strength rating. Beyond the specific shackles illustrated in FIG. 4, it should be appreciated that first shackle 114 and second shackle 116 may, in alternative embodiments, include hooks, clips, locking carabineers, or other similar attachment features for attaching equipment to lanyard 100 and attaching lanyard 100 to other surfaces such as vehicles.

(17) In another use case, lanyard 100 is attached to a military personnel's kit, such as belt or nick sack. More particularly, the first attachment loop 102 is fixedly attached to the military kit. Necessary equipment is attached to the second attachment loop 104; because lanyard 100 is adjustable via adjustment feature 108, distance between the necessary equipment and the attachment point on the kit is controllable and customizable by the user. It should be appreciated that the second attachment loop 104 could be fixedly attached to the kit, such that equipment is attached to the first attachment loop 102. Alternatively, both of the first attachment loop 102 and the second attachment loop 104 could be fixedly attached to the military kit. In this embodiment, lanyard 100 operates as an adjustable strap for holding equipment to the military kit.

(18) While the use cases above describe several modes of using lanyard 100, it should be appreciated that lanyard 100 may be implemented in any situations or circumstances where adjustable length fastening and attachment is required.
