Definitions

  • the present invention relates broadly to a flexible and elongate conductor member and relates particularly, though not exclusively, to a conductor member such as an electrical cable or wire.
  • Cords, ropes, cables, strings, wires and leads are used in many day to day applications. Because of the length and flexible nature of these devices, tangling and knotting is a frequent occurrence which can affect their functionality and /or longevity.
  • One example which illustrates the problems often encountered is with electrical wires or leads extending from earpieces used in conjunction with mobile phones or portable music players. Quite often when the ear piece is not in use, it is left in a pocket or bag where it invariably tangles and forms knots providing a nuisance for the user of the device and also affecting the performance of the wires.
  • Another example is shown with electrical, audio and data leads extending from appliances such as home stereo equipment and computer equipment.
  • United States patent no. 6,111,202 discloses a dual conductor electrical cable of a ribbon-like construction and having a protrusion and a matching depression on respective opposing surfaces.
  • the cable is specifically designed to be coiled with the protrusion nesting within the depression in this coiled configuration.
  • the protrusion and mating depression of the cable of this US patent may alternatively be formed to include a barb or detent designed to intimately retain adjacent coils of the cable in mated contact.
  • the cable is nested in this coiled configuration with the protrusion accurately aligned with the mating depression along its entire length and the cable mates with itself in one rotational position only.
  • a flexible and elongate conductor member including an exposed surface having engaging means being adapted in a plurality of rotational orientations and on contact with the conductor member or another object to inhibit relative movement between contacting portions of the conductor member, or contacting portions of the conductor member and the object.
  • the engaging means provides releaseable and interlocking engagement between the contacting portions. More preferably the engaging means includes a plurality of protrusions being separated by a plurality of recesses, at least one of the protrusions being capable of interlocking with at least one of the recesses to prevent movement between these contacting portions. Alternately the engaging means includes one element having a series of hooks and an adjacent or other element having a series of loops, the hooked element capable of interlocking with the looped element to inhibit movement between these contacting portions.
  • the engaging means provides a releaseable bond between the contacting portions.
  • the engaging means includes an adhesive applied to or forming part of the exposed surface and being capable of releaseably adhering to the conductor member or the other object to prevent relative movement therebetween.
  • a conductor tie being elongate and at or adjacent opposite ends designed to engage itself and at least one of a plurality of the conductor members according to the preceding aspect of the invention, said members being encircled by the conductor tie.
  • the conductor tie is in the form of a flexible strip on each of its opposing surfaces having a plurality of protrusions separated by a plurality of recesses, one or more of the protrusions on one of the opposing surfaces being designed to releasably engage one or more of the recesses on an opposite of said surfaces.
  • the protrusion/ recesses of the conductor tie are of a substantial identical cross-sectional shape to those of the conductor members to permit interengagement of the conductor tie and said members.
  • the protrusions and recesses of the engaging means include respective flutes and elongate channels each being arranged generally parallel to one another and coaxial with the conductor member. More preferably the protrusions and recesses are in cross section at least in part shaped complementary to one another to assist with their releaseable and interlocking engagement. Even more preferably the flutes and channels are circumferentially spaced and occupy substantially the entire circumference of the elongate member.
  • the flutes and channels are at least in part cross section tapered, flared or bulged outward to provide releaseable keyed engagement with each other. More preferably the flutes are constructed of a resiliently flexible material to provide at least partial press fitting of the flute within the interengaging channel.
  • the conductor member is contacted with itself whereby the engaging means reduce the likelihood of said member tangling or knotting with itself.
  • the other object is one or more other conductor members of the invention whereby contact and interengagement of the engaging means of said members at least lessens the likelihood of tangles or knots.
  • the other object is an attachment device including an exposed surface having other engaging means being adapted to contact the engaging means of the elongate conductor member for releaseable attachment of said conductor member to the attachment device.
  • the other engaging means is at least in part shaped in cross section complementary to the engaging means of the conductor.
  • the attachment device is adapted to be fixed or otherwise mounted to a building structure or furniture.
  • the flexible and elongate conductor member is in the form of an electrical cable or wire, or acoustical lead or wire.

  • Figure 20 is a cross-sectional view of a plurality of the conductor members such as that shown in figures 1 and 2 arranged in a bundle and encircled by a conductor tie according to another aspect of the invention.
  • the conductor member 10 is in this example an electrical conductor member in the form of an electrical cable but for ease of reference is not illustrated with its conductive core.
  • the electrical cable 10 includes an insulating and protective sheath 12 formed about the core (not shown) and including an exposed surface designated generally as 14 having engaging means.
  • the engaging means of the preferred embodiment of figures 1 and 2 includes a plurality of protrusions or flutes 16 separated by a plurality of recesses or elongated channels 18.
  • the flutes and channels 16 and 18 of this example are in cross-section shaped substantially complementary to one another.
  • the flutes 16 and channels 18 are arranged parallel to one another and coaxial with the electrical cable 10 with the flutes/ channels 16/18 being equally spaced circumferentially about the exposed surface 14.
  • the flutes 16 and channels 18 are bulged outwardly and inwardly, respectively, and in cross-section are generally crown- shaped with inwardly tapered opposing walls such as 20 and 22 (see Figure 2).
  • Figure 3 illustrates a variant of the electrical cable 10 of figure 1.
  • the electrical cable 10 of this variant is most typically a power cable including three (3) coaxial conductors including earth 24, neutral 26 and active 28 conductors. These conductors 24/26/28 are housed within a cylindrical jacket 30 about which the outer protective sheath 12 is formed.
  • the sheath 12 includes a plurality of the flutes 16 separated by the channels 18 and equally spaced circumferentially about the electrical cable 10.
  • the flutes such as 16A and 16B are generally dome-shaped including opposing barbed portions such as 32 and 34 designed to engage or interlock with the respective channels 18A and 18B.
  • the outer sheath 12 is formed of a resiliently flexible material which permits press fitting of the flute such as 16A into the corresponding recess such as 18A.
  • the electrical cable 10 of figures 1 and 2 can in a similar manner to the cable of figure 3 be interengaged or interlocked. In both examples this interengagement serves to inhibit relative movement between contacting portions of the conductor member in the form of the electrical cable 10.
  • the contacting portions of the embodiment of figure 3 is generally defined by the interlocking flutes 16A/B and channels 18A/B which provide releasable attachment of the electrical cable 10. It has been found that this form of releasable engagement or attachment reduces the propensity for the cable 10 to tangle or knot with itself or another cable. This can be contrasted with conventional electrical conductors such as cables or wires which can readily slide when in contact with one another and this is understood to lead to tangling or knotting of these traditional or conventional cables.
  • Figure 4 illustrates another embodiment of a flexible and elongate conductor member according to the invention.
  • This embodiment is typically of a dual conductor configuration including a pair of spaced apart conductors (not shown) contained within the protective sheath 12.

  • the flutes/ channels such as 16A/18A are, in a similar manner to the embodiment of figure 3, designed to interengage with themselves or corresponding flutes/ channels of another dual conductor cable to inhibit relative movement and the likelihood of the cable(s) tangling or knotting.
  • Figures 5 and 6 illustrate further embodiments of a conductor member designed specifically to interengage with a corresponding conductor member to inhibit relative movement and their propensity to knot or tangle.
  • the conductor member 10 of figure 5 includes three (3) upper flutes 16A to 16C and two (2) lower flutes 16D and 16E formed on opposing exposed surfaces of an intermediate sheath 12.
  • the intermediate sheath 12 includes one or more conductors.
  • the flutes 16A to 16E are arranged parallel to one another and spaced by intermediate recesses or channels such as 18A to 18C which are in cross- section shaped complementary to the flutes such as 16A.
  • the lower pair of flutes 16D and 16E of the conductor 10 interengage with corresponding recesses or channels 18A' and 18B' of the or another conductor member 10'.
  • the conductor members 10 and 10' of figure 6 similarly interengage or mate with one another wherein the protrusion or flute 16A is press fit within a corresponding recess or channel 18A' of the other conductor member 10'.
  • the flutes and channels such as 16A/18A of the embodiment of figure 6 are in cross-section shaped substantially circular and the flutes such as 16A and 16B house respective conductors such as 25A and 25B.
  • FIG 7 schematically illustrates three (3) of the conductor members 10A, 10B and 10C bundled together and interengaging with each other with a reduced likelihood of tangling or knotting of these electrical cables.
  • the electrical cables 10A to IOC may be constructed in accordance with any one of the embodiments of figures 1 to 6. It is important to note that the cables such as 10A and 10B can be bundled and interengage with one another in a plurality or in this example multiplicity of orientations where one of the cables such as 10B may be twisted or rotated along its length. In this example, the electrical cable 10B can take a multiplicity of rotational orientations and still interengage with an adjacent of the cables such as 10A.
  • the flutes 16 may engage with a corresponding channel 18 for a short length, and then be twisted and interlock with another channel (not designated) of the contacting conductor such as IOC. It should be appreciated that interengagement of the electrical cables such as 10A to 10C is relatively random and does not rely upon precise alignment of for example the corresponding flutes/ channels.
  • Figure 8 is a stereo headset 35 including an audio device 36 connected to an intermediate lug 37 via a coaxial cable or lead 38.
  • the lead 38 is separated above the lug 37 into a pair of earphone leads 39A and 39B which connect to respective earphones 41A and 41B.
  • the earphone leads 39A/B are each constructed from a conductor member of an embodiment of the invention such as that illustrated in any one of figures 1 to 6.
  • the earphone leads 39A/B can conveniently be bundled together wherein they attach to each other for stowage with a reduced propensity for tangling.
  • the earphone leads 39A/B are separated to allow the earphones 41 A/ B to be inserted in the ears for listening.
  • Figures 9 and 10 show interengagement of one of the conductor members 10 of figures 1 to 6 in a coiled arrangement such as 40.
  • the electrical conductor 10 interengages itself randomly along its length at contacting locations where corresponding flutes/ channels 16/18 align. This relatively random interengagement of the cable 10 with itself has been found to reduce the propensity for tangling or knotting.
  • Figure 10 shows a typical application for the coiled arrangement 40 of the cable 10 where it is a power supply for a domestic appliance such as an iron 42.
  • FIGs 11 to 14 illustrate alternate embodiments of flexible and elongated conductor members according to the invention.
  • Each of these embodiments includes different forms of engaging means located on an exposed surface of the conductor member and designed on contact with the conduct member itself or another object to inhibit relative movement between these contacting portions.
  • this interengagement of the conductor member with itself or another element reduces the likelihood of tangling or knotting of the conductor member.
  • Figure 11 shows one form of the engagement means including a pair of opposing strips 60 and 62 adhered or otherwise fixed to respective opposing semi-circular surfaces of a cable or wire (not designated).
  • One of the strips 60 includes a series of hooks such as 64 whereas the other strip 62 includes a series of loops (not shown or designated) each being embodied in the form of VELCRO.
  • the hooks such as 64 and loops may alternately be formed integral with an exposed surface or outer protective sheath of the cable 10.
  • the hooked or looped strips 60 and 62 may also be positioned alongside one another and wrapped around the inner cable 10 in the form of a helix.
  • Figure 12 is a variation of the engaging means of figure 10 and includes an array of rectilinear blocks such as 66 extending from an exposed surface of a protective sheath of the conductor member 10.
  • the locks such as 66 are separated by recesses or voids such as 68 or a similar width to the blocks 66 themselves.

  • the embodiment of figure 13 is in the form of a generally flat conductor member 10 having engaging means in the form of a stepped profile 70 formed along its opposing edges.
  • the stepped profile 70 includes alternate notches 72 and ridges 74 extending alongside one another and the opposing edges of the conductor member 10. It will be appreciated that the complementary-shaped notches 72 and ridges 74 when contacting or interengaging with one another inhibit relative movement and as such reduce the propensity for knots or tangles.
  • Figure 14 schematically illustrates another form of the engaging means including adhesive strips such as 76 located about an exposed surface of the conductor member 10.
  • the adhesive strip 76 is in this example formed as a helix about the conductor member 10 which may be coated in two different adhesive substances. It will be appreciated that contact of the adhesive strip such as 76 with the conductor member itself or other conducted members forms a temporary bond between said members which restricts their relative movement and reduces the likelihood of tangles or knots.
  • Figure 15 is a schematic representation of the conductor member 10 of any one of the embodiments of figures 11 to 14 in contact with itself to inhibit relative movement and thus reduce the likelihood of tangles.
  • the schematic of figure 16 shows a pair of conductor members 10 and 10' such as those described and illustrated in figures 10 to 13 in contact with one another in such a manner as to restrict or inhibit relative movement and lessen the likelihood of tangles.
  • the conductor member or cables such as 10 can be contacted in a multiplicity of positions which provide interengagement and inhibit relative movement.
  • the cables 10 can preferably be randomly coiled or bundled with contact and interengagement at a plurality of random points. This random interengagement limits relative movement between the cable(s) and reduces their propensity for tangling or knotting.
  • Figure 16 illustrates a pair of conductor members 10A and 10B similar to that of figures 1 and 2 in releaseable engagement with an object in the form of an attachment device 80.
  • the attachment device 80 is in the form of an elongate strip including a plurality of longitudinally extending and transversely spaced apart flutes 82 and elongate channels 84.
  • the flutes/ channels 82/84 are in cross-section shape complementary to the flutes/ channels 16/18 of the conductor members 10A/B.
  • the conductor members such as 10A are thus designed to releaseably attach to the attachment device 80 by press fitting of one or more of the member flutes such as 16B into a corresponding recess such as 84B of the attachment device 80.
