The present invention generally relates to a fastener. More specifically, this invention relates to a helical coil fastener configured to fasten wide variety of objects, for example, cords, keys, etc.
Generally, lashing is a type of fastening technique, done by way of successive wrapping of wires or webbings to secure and fasten two or more items together in a rigid manner Variety of lashing strap and cord fasteners are available for removably tying down an object to a support or structure. Typically, these fasteners are configured to tension, in order to more securely tie the object to the support.
Existing fasteners include elastomeric straps, see for example U.S. Pat. No. 5,325,568 (Bruhm, 1994), elastomeric cords, see for example U.S. Pat. No. 6,014,794 (Mc Coy, 2000), flexible curled cords, see for example U.S. Pat. No. 5,515,580 (McHenry Jr., 1996) and coiled springs, see for example U.S. Pat. No. 1,519,854 (Lockwood, 1924).
Known fasteners also include devices having an elastic elongate member as well as a non-elastic elongate member. A variety of fastening implements or fasteners are known for fastening to a support, a load such as a package, or for fastening the lashing itself and thereby forming a loop. These fastening implements include hooks, hook and ring combinations, for example U.S. Pat. No. 4,569,108 (Schwab, 1986). While many of these fastening devices are attached to the ends of an elongate member, it is also known to employ fastening implements that can be positioned at substantially any point along an elongate fastening member, see for example U.S. Pat. No. 5,383,259 (McIntire, 1995). Generally, the fastening implements include rigid components for example metal or rigid plastic. Such rigid implements can damage the surface of an object that is secured by a tie-down. Also, these implements can damage the tie-down device, when the fastening implement is fastened to form a loop in the device.
Typically tie-down devices such as described above are provided in specific lengths, see for example U.S. Pat. No. 6,099,060 (Towers, 2000). But it is also known to employ fastening techniques that allow placement of one or more fasteners along substantially the entire length of the elongate member, thereby enabling a user to employ a selected portion of the elongate member.
Prior art fastening devices and techniques have thus resulted in a variety of useful solutions to common tie-down fastener problems. Further, the existing reusable fastener may be lost, if not conveniently attached to the portable object where it is used. However, there exists a need for improved fasteners that provide the capability to secure an object to a structure without utilizing fastening implements or components and the user of the device can employ either a portion or substantially the entire length of the fastening device.

In one embodiment, the trunk lashing 116 made of a flexible and resilient material, comprises a first end 116a and second end 116b, defined by a plurality of helical coils 122. The first end of the trunk lashing is attached to an end of the stump. In one embodiment, the plurality of helical coils 122 in the first end 116a of the trunk lashing 116 is configured to wrap on a portion of the object 230 extending from the stump 114 towards the second end 116b of the trunk lashing 116, thereby a user ensures fastening a desired portion of the object 230. In one embodiment, the helical coil fastener 200 further comprises a dorsal face 118 of the helical coil 122, and a ventral face 120 of the helical coil 122.
In one embodiment of the present invention, the stump 114 is defined by an arcuate stump, or a tapered stump. In some embodiments, the stump 114 is a tapered stump, thereby said tapered stump causes the rooting lashing 110 to be urged towards the rooting eye 112 keeping it tight. The arcuate stump comprises an arcuate curve, which is beneficial on implementing embodiments with trunk lashing 116. This is because, the arcuate curve tends in the direction to the configuration of the trunk lashing 116.
In one embodiment, the trunk lashing 116 connect to the opposite end of the stump 114 from the end where the rooting lashing 112 connect. The trunk lashing 116 is generally defined by a body created by the sweep of a closed two-dimensional curved profile comprises no concavities or flats. The profile is swept normal to a substantially helical three-dimensional curve. In some embodiments, the direction of the pitch of the substantially helical curve defining the trunk lashing 116 is opposite to the direction of the helical curve of the rooting lashing 110. The orientation of the stump 114 and the trunk lashing 116 is such that the stump 114 lies in a path generally tangent to a circle circumscribing the helical curve of the trunk lashing 116 and the circle is substantially perpendicular to the axis of the helical curve of the trunk lashing 116. Therefore, of necessity the helical axes of the rooting lashing 112 and trunk lashing 116 lie generally in the same plane and side by side.
