  • the lateral portion may comprise a lug, lip, rib, ridge, ear etc.
  • the lateral portion may extend from at least one side of the protrusion.
  • the lateral portion may be substantially arcuate in shape. It is preferred that the protrusion includes a stepped annular portion around the top face thereof. .

  • Figure 8 shows the tie device shown in Figure 7b coupled in a different manner
  • Figure 9 shows coupled components of a tie device according to an alternative embodiment of the present invention.
  • FIG. 10 shows an alternative coupling arrangement of the tie device shown in Figure 9.
  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to Figure 1, a preferred embodiment of the invention is a flexible tie device 10.
  • the device 10 includes a base strip 12 having first and second opposing surfaces 14 and 16 respectively.
  • a plurality of upstanding formations in the form of buttons 18 and recesses in the form of holes 20 are disposed on first opposing surface
  • the holes 20 proceed through the base strip 12 from the first opposing surface 14 to the second opposing surface 16. In an alternative embodiment, the holes pass only part way through the base strip, 12.
  • buttons 18 are shaped as two frusto-conical surfaces 22 and 24 sharing a common axis and joined at their tapered ends.
  • the bore surface 26 of the holes 20 includes a surface tapering inwardly of the hole, the surface 26 shape being substantially complementary to the shape of the buttons 18.
  • the flexible nature of the device 10, in cooperation with the button 18 and hole 20 shapes mean that, if the strip 12 is bent into a loop shape, any one of the buttons 18 may releasably snap-lockingly engage with a hole 20. This is because the diameter of the top 28 of each button 20 is slightly larger than the diameter of the narrowest lateral cross section 30 of each hole 20.
  • the buttons 18 and holes 20 are disposed at regular intervals in a longitudinal row 32, the buttons 18 and holes 20 being arranged as alternate buttons and holes.
  • the device 10 is typically made from semi-rigid plastics, such as polyethylene or polypropylene.
  • the strip 10 is manufactured from elasticised plastics or rubber or neoprene.
  • the device 10 is supplied as a roll of, for example, 5 metres of length of device 10.
  • the user manually secures the loose end of the device 10 on the roll and removes a desired length of the device 10 from the roll. For example, if the user is to secure together four lengths of standard home extension cord they may withdraw approximately 10 cm of the device 10 from the roll.
  • the device is then wrapped around the extension cables at a predetermined point along the cables in one of several ways.
  • the strip may be wrapped around the cables either with the buttons 18 directed inwardly of the cables, the buttons 18 directed outwardly from the cables, or the device 10 wrapped around the cables with a single twist to form a Moebius strip when a button 18 is engaged with a hole 20.
  • buttons 18 are buttons 18 with the corresponding number of holes 20.
  • the nature of the shape of the holes 20 means that the user may engage a button 18 with a hole 20 by forcing the button to enter the hole 20 from either the first opposing surface 14 or the second opposing surface 16.
  • Figures 2 to 5 illustrate alternative embodiments of the invention where like numerals denote like parts.
  • the alternative embodiment of the device 10 illustrated in Figure 2 employs two side by side rows 32 of buttons 18 and holes 20 where the rows are offset such that a button 18 in one row is laterally adjacent a hole
  • FIG. 3 illustrates four side by side rows 32, also where a button 18 in one row is laterally adjacent a hole 20 in an adjacent row, etc.
  • FIG. 4 illustrates four side by side rows 32 where the holes 20 in one row are adjacent the holes 20 in an adjacent row and the buttons 18 in one row are adjacent the buttons 18 in an adjacent row.
  • Embodiments of the device 10 illustrated in Figures 2 to 4 are used in an identical manner to the device 10 illustrated in Figure 1
  • the width of the device 10 is typically 1 cm, however the device width may be more or less than 1 cm depending on the desired application. For example the width may range from micro-range (approximately 1 ⁇ m) to 1+ metres.
  • the width of the device will depend on the intended application for the device. Also, the type of application for the device will determine which embodiment of the invention is used. For example, to secure several lengths of electrical cable together may require the embodiment of the device 10 illustrated in Figure 1, having a width of 5mm. On the other hand, to secure several 205L drums together may require the embodiment of the device 10 illustrated in Figure 3, having a width of 20cm.
  • FIG. 5 illustrates an alternative embodiment of the invention illustrated in Figure 1, where like numerals denote like parts.
  • This embodiment includes perforations 34 formed in the base strip 12.
  • the perforations 34 are arranged in lateral rows 36, the rows being disposed laterally to the strip at regular intervals. These perforations allow the user, once a desired length of device 10 is taken from the roll, to tear the desired length of device 10 from the roll along the perforations
  • a method for manufacturing the device 10 is by moulding or extruding a continuous base strip 12 onto a travelling belt .
  • This strip 12 is then partially cooled before being passed between a pair of rollers disposed one on either side of the opposing surfaces 14 and 16 of strip 12.
  • the rollers form the holes 20 and button blanks 38 illustrated in Figure 6.
  • the product is then cooled before passing a heated roller over the device which contacts the tops 40 of the button blanks and deforms the tops 40 to form the buttons 18 illustrated in Figure 1, for example.
  • buttons 18 are formed without the need to draw the device 10 from a die and thus the device 10 can be produced in a continuous process rather than a batch process . Additional embodiments of the present invention are shown in Figures 7a to Figure 10.
  • a button 50 is shown which is in the form of a cylindrical upstanding spigot with a flat top surface 51 and a small frusto conical surface 51 and a small frusto conical region 52 just below the top surface 51.
  • One side of the spigot 50 is provided with an arcuate rib 53 which extends laterally in a substantially horizontal direction.
  • the ridge 53 extends approximately one quarter or one half of the way around the periphery of the spigot 50.
  • a tie device 54 may be provided with three rows of alternating buttons and holes 53, 55. Each row of protrusions and holes 56, 57, 58 is aligned with the other rows 56, 57, 58. A button in one row is aligned at right angles with an adjacent hole of another row. In this way buttons and holes alternate along a row and across rows.
  • a second tie device 59 is provided which has an identical bottom face to the top face of the first tie device 54.
  • the two tie devices 54, 59 are coupled together at right angles so that the buttons 53 of tie device 54 protrude through holes 60 of tie device 59 and vice-versa.
  • each protrusion provides a snap engagement between each button 53 and the hole 60 in which it is inserted. As shown in Figure 7b the ridge 53 protrudes beyond the top surface of tie device 59 and acts as a retaining means which prevents easy decoupling of the two tie devices 54, 59.
  • Figure 8 shows the tie devices 54 and 59 when coupled in axial alignment and therefore at 90° with respect to the coupling arrangement shown in Figure 7b.
  • Figure 9 shows tie devices 54 and 59 coupled at right angles but with the top face of tie device 53 coupled to the bottom face of tie device 59. This figure shows how the buttons of tie device 53 still protrude through the holes beyond the upper surface of tie device 59, but are well below the level of the buttons 61 of tie device 59. The ridges 53 still protrude beyond the upper surface of tie device 59 as previously described.
  • Figure 10 shows the tie devices 54 and 59 coupled together top face to bottom face but in axial alignment.
  • the configuration of the device allows a user to cut a desired length of device from the greater length of the device, rather than having to obtain a tying device of the desired length.
