DETAILED DESCRIPTION

[0030] While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail a preferred embodiment of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to embodiments illustrated.

[0031] Referring to FIGS. 1 and 2, a cord bracelet 10 for use in emergency situations is shown. The bracelet includes a cord portion 12 and a connecting mechanism 14. While the present invention will be described in the form of a bracelet for wearing around an individual's wrist, it will be appreciated that the present invention is capable of use in many forms, including watch bands, anklets, belts, necklaces, dog collars, hat bands, and other items of articles which can be readily made from paracord while not departing from the scope and spirit of the present invention. It will be also be appreciated that while the present application discloses the use of a paracord as an embodiment of the invention, any type of cording, yarn or other material can be used without departing from the scope and spirit of the present application.

[0032] In an embodiment, the cord portion 12 is weaved to a length suitable for wearing around a user's wrist. The cord portion 12 is capable of multiple widths, requiring additional cord to weave to the appropriate length. In an embodiment, the total paracord length required for weaving into the bracelet is, for example, approximately 10 to 28 feet. It will be appreciated that any length of paracord may be used. Additionally, in an embodiment, the cord 12 is a nylon kernmantle cord, such as military specification 550 paracord.

[0033] At one end 11 of the cord portion 12 is a generally U-shaped shackle 16. In an embodiment, the cord 12 is looped around the arcuate portion 18 of the shackle 16 multiple times, as is generally known in the art.

[0034] In an embodiment, shackle 16 includes ends 19, 21 respectively having apertures 20 and 22 for retaining a pin 24. In an embodiment, the inner walls of apertures may include threads 32. The pin 24 contains a head 26 at a first end 40, a threaded portion 28 at the second end 42 adapted to threadably engage the threads 32 of apertures 20 and 22, and a shaft 30 disposed between the two head 26 and threads 28. When installed, the shaft 30 extends between the two apertures 20 and 22 in the shackle 16. The head 26 is sized larger than the diameter of the aperture 20 such that the head 26 abuts the shackle outside edge 34 and retains the pin 24 in the aperture 20, preventing the pin 24 from passing completely through both apertures 20 and 22 in the shackle 16. In an embodiment, the head 26 of the pin 24 is knurled to provide a gripping means when inserting or removing the pin 24, as shown in FIG. 4. Additionally, the knurled head 26 prevents snagging on clothing and the like which frequently occurs when using a flat headed pin commonly used in other shackles. The threaded end 28 is adapted to engage the interior threads 32 of the apertures 20 and 22. Because both apertures 20 and 22 are threaded, the pin can be completely removed by engaging the threaded portion 28 of the pin 24 with the interior threads 32 of the apertures 20 and 22. Accordingly, the pin 24 can be replaced with a different pin. When the pin 24 is completely inserted in the apertures 20 and 22, the second end 42 of the pin 24 lies substantially flush with the outside edge 34 of the shackle 16 and the head 26 abuts the shackle 16, as shown in FIG. 4. In an embodiment, the pin 24 and shackle 16 are each made of metal, such as stainless steel. Alternatively, the shackle may be composed of plastic, carbon fiber or other metal.

[0035] In another embodiment, the pin 124 is a break-away pin, as shown in FIGS. 5 and 6. The head 126 of the pin 124 may be knurled to provide a gripping means when inserting or removing the pin 124. The pin 124 may include an annular groove 150 circumferentially disposed on the shaft 130. The groove 150 extends radially inwardly from the outside surface 154 of the shaft 130. As such, the groove 150 functions as a weakened break-away feature for the bracelet 10 by shearing at the groove 150 location when a lateral force is applied to the pin 124, such as, for example, when the article worn by a user gets snagged on something. In another embodiment, a plurality of annular grooves 150, 152 are circumferentially disposed on the shaft 130. The first groove 150 is disposed adjacent the threaded end portion 128. The second groove 152 is disposed adjacent to the head 126. The grooves 150, 152 are configured so that the grooves 150, 152 substantially align with the interior edge 160 of the shackle 116 when the pin 124 is substantially inserted into the shackle 16, such as when the article is worn by a user. The alignment of the grooves 150, 152 with the interior edge 160 of the shackle 16 creates a shear plane. When a substantial lateral force is applied to the pin 124, the pin 124 will preferably shear at one or more of the grooves 150, 152, decoupling the tongue 80 from the shackle 116 to avoid or minimize injury to a wearer, as shown in FIG. 7.

[0036] In an embodiment, the pin 124 shears at one or more of the groove locations when approximately 30 to 100 pounds of lateral force is applied. In an embodiment, the pin 124 shears at approximately 60 pounds. When broken, the pin 124 preferably disassembles into multiple pieces corresponding to the portions outside of the grooves and the portion disposed between the grooves, thereby causing the article to fall apart before harm is caused to the user. In an embodiment, the pin 124 is constructed of a plastic.

[0037] In another embodiment, the pin may be a clevis pin 224, as depicted in FIGS. 8-10. The clevis pin 224 may be constructed of metal, such as, for example, stainless steel, or plastic, carbon fiber or other material. The clevis pin 224 includes a flat head 226 at a first end 240 and a detent structure 270 disposed at a second end 242. In an embodiment, the head 226 of the pin 224 is knurled to provide a gripping means when inserting or removing the pin 224. In an embodiment, the detent structure 270 may include a ball bearing 272 extending radially from the pin shaft 230 and a spring 274 adapted to radially bias the ball 272 outwardly. The width of the shaft 230 and the detent structure 270 are slightly wider than the diameter of the apertures 220, 222. The detent structure 270 is depressible when a force is applied such that the clevis pin 224 can pass through apertures 220, 222 when the detent structure is depressed. In an embodiment, apertures 220 222 in the shackle 216 do not include threads. As the clevis pin 224 is inserted into apertures 220, 222 of the shackle 216, the detent structure 270 is depressed due to the force applied by the inner walls of apertures 220 and 222. When the clevis pin 224 is substantially inserted into the shackle 216, the second end 242 of the pin 224 extends beyond the outside edge 234 of the shackle 216 and the detent structure 270 is biased outwardly. The detent structure 270 thereby substantially prevents the pin 224 from being inadvertently removed from the shackle 216 without a force sufficient to depress the detent structure 270 while passing through apertures 220, 222.

[0038] In another embodiment, the pin 324 is a break-away pin, as shown in FIGS. 11-13. In an embodiment, the pin 324 may be constructed of a plastic. The pin 324 may include an annular groove 350 circumferentially disposed on the shaft 330. In another embodiment, a plurality of annular grooves 350 and 352 are circumferentially disposed on the shaft 330. The first groove 350 is preferably disposed adjacent the second end 328 and a detent structure 370. In an embodiment, a plurality of detent structures or projections 370, 372 may be respectively disposed on a plurality of pliable legs 374 adjacent the second end 328 of the pin 324, the legs 374 being elastically depressible when an inwardly radial force is applied to the legs 374, as shown in FIG. 12. The second groove 352 is circumferentially disposed adjacent to the head 326. The grooves 350 and 352 are configured so that the grooves 350 and 352 respectively substantially align with the interiors edge 360 of the shackle 316 when the pin 324 is substantially inserted into the shackle 316. The alignment of the grooves 350 and 352 with the interior edge 360 of the shackle 316 creates a shear plane. As shown in FIG. 13, when a substantial lateral force is applied to the pin 324, the pin 324 will preferably shear at one or more of the grooves 350 and 352, decoupling the tongue 80 from the shackle 316 and avoiding or minimizing injury to a wearer of the article. In an embodiment, the clevis pin 324 shears at one or more of the groove 350 locations when approximately 30 to 100 pounds of force is applied. In an embodiment, the clevis pin 324 shears at approximately 60 pounds. When broken, the clevis pin 324 preferably disassembles into multiple pieces corresponding to the portions outside of the grooves and the portion disposed between the grooves, thereby allowing the article to fall apart.

[0039] It will be appreciated that each of the previously disclosed shackle and pin embodiments are compatible with an adjustable tongue 80 adapted to change the size of the woven corded article to be worn by a user. Referring to FIGS. 1 and 2, a tongue 80 is disposed at opposing end 13 of corded portion 12. The tongue 80 may be constructed of steel, plastic, carbon fiber, other metal or other strong material. In an embodiment, the tongue 80 is generally arcuate in shape, and includes a plurality of adjustment apertures 81, 82, 83, 84 extending through the width of the tongue 80. In an embodiment, the tongue 80 includes four adjustment apertures 81, 82, 83, 84. It will be appreciated that tongue 80 can have any number of adjustment apertures for adjustment purposes. The adjustment aperture 84 is preferably disposed adjacent opposing end 13 of corded portion 12 and is adapted to engage the tongue 80 with the cording 12. In an embodiment, the tongue 80 is coupled to the cording 12, such as for example, weaving the cording 12 by looping the cording 12 through aperture 84 one or more times to ensure a proper engagement between the tongue 80 and the cording 12. The other adjustment apertures 81, 82, 83 provide an adjustment mechanism whereby, the inner diameter of the bracelet or anklet 10 can be easily modified as desired to fit a user. In an embodiment, the adjustment apertures 81, 82, 83 are each disposed on the tongue 80 adjacent one another and spaced relative to each other in approximately inch increments throughout the length of the tongue 80 so that the diameter of the bracelet may be changed in inch increments for a total of inches depending on which adjustment aperture 81, 82, 83 is selected.

[0040] Though the following description refers to the embodiment shown in FIGS. 1 and 2, the interaction between the shackle 16 and tongue 80 is substantially identical for each embodiment discussed previously. To connect the shackle 16 to the tongue 80, the desired adjustment aperture 81, 82, or 83 of the tongue 80 is selectively substantially axially aligned with apertures 20, 22 of the shackle 16, depending on the desired inner diameter of the bracelet 10, and the pin 24 is inserted through one of the adjustment apertures 81, 82, or 83 in the tongue 80 to secure the two ends 11, 13 of the corded portion 12. When inserted, the pin 24 extends from aperture 20 at one end of the shackle 16, continuing through one of the adjustment apertures 81, 82 or 83 of the tongue 80, and is retained by aperture 22 at the opposing end of the shackle 16, thereby releasably coupling the tongue 80 to the shackle 16.

[0041] The tongue 80 and shackle 16 are adapted to substantially prevent the tongue 80 from extending past the arcuate portion 18 of the shackle 16 when the pin 24 is inserted through aperture 83, thereby adjusting the bracelet or anklet 10 to its shortest length. In an embodiment, the length of the interior of the shackle 16 is greater than the length of the tongue 80 from the tightest adjustment aperture 83 to the loosest adjustment aperture 81.

[0042] Referring now to FIG. 14, the preferred paracord of the bracelet 10 is capable of use, such as, for example, in an emergency situation. To use the corded portion 12, which is preferably paracord, the shackle 16 and tongue 80 are disassembled. At the end 13 of the cord portion 12 coupled to the tongue 80, two loose ends 90 and 92 of corded portion 12 pass through a loop 94, as shown in FIG. 14. The loose ends 90 and 92 may be pulled outwardly from underneath the loop 94 and the remainder of the corded portion 12 can be unraveled. Once unraveled, the user will have, for example, between 10 to 28 feet of paracord, depending on the length and width of the article, which may be used for a plurality of purposes. Because the shackle 16 is weaved onto the corded portion 12, the shackle 16 may also be used to attach the unraveled corded portion 12 to an external object to ensure a secure connection between the cord and the object.

[0043] While the invention has been described with respect to specific examples including presently preferred modes of carrying out the invention, those skilled in the art will appreciate that there are numerous variations and permutations of the above described systems and techniques that fall within the spirit and scope of the invention
