  • Module 1 includes an annular cylindrical base 2 having a substantially planar storage face 3.
  • a retaining formation 4 upwardly extends from base 2 such that module 1 and a like second module 5 are interlockingly engageable to provide a storage device 6 having a storage channel 7 intermediate faces 3.
  • respective bases 2 of interlockingly engaged modules 1 and 5 have substantially axially aligned circumferential peripheries.
  • modules 1 and 5 are identical, and designated by different reference numerals only for the sake of convenient explanation. It will be further appreciated that module 1 is engageable with a suitably designed non-identical module, should a particular embodiment warrant this. However, the ability to use identical modules is advantageous in a practical sense. From a manufacture standpoint, it is only necessary to produce one type of module, which reduces production costs. From an end-user standpoint, it is not necessary to locate two different complimentary halves. This saves time, and further facilitates convenient reuse of modules even where one module 1 or 5 of a particular device 6 is damaged.
  • the term "upwardly" is used only to provide a frame of reference for a single module. That is, where two modules are engaged, their respective formations 4 do not necessarily extend in a like direction. Indeed, in the present embodiment they extend toward one another.
  • retaining formation 4 includes plurality of latch members 15 and a complimentary plurality of catch members 16.
  • Latches 15 and catches 16 upwardly extend from face 3.
  • catches 15 extend from a circular catch path 18, whilst catches 16 extend from a concentric circular catch path 19.
  • catches 15 extend from a circular catch path 18, whilst catches 16 extend from a concentric circular catch path 19.
  • a diametrically opposite catch member In the present embodiment, which utilises an even number of catches 16, for each catch member there is provided a diametrically opposite catch member. In embodiments utilising an odd number of catches, for each catch member there is provided a diametrically opposite latch member.
  • Latches 15 and catches 16 are relatively located to facilitate the interlocking engagement of modules 1 and 5 upon opposition of faces 3 and appropriate rotational offset between modules 1 and 5.
  • the requisite level of angular offset is dependant on the specific configuration and design of retaining formation 4 and the number of latches 15.
  • the basic angular offset is about 22.5 degrees.
  • 45 degree angular variations are allowable. That is, a 45 degree angular variation is effectively the same as no angular variation at all.
  • angular variations of twice the basic angular offset are allowable.
  • basic angular offsets of up to and including 90 degrees are used. It will be appreciated that one embodiment making use of a 90 degree basic angular offset includes a single latch 15 diametrically opposite a single catch 16.
  • Formation 4 further includes a plurality of spacers 17 upwardly extending from a circular spacer path 20 on face 3.
  • Path 20 is concentric with paths 18 and 19.
  • Spacers 17 abuttingly engage the face 3 of an opposed module upon interlocking engagement to maintain a threshold separation of dimension 21 between the respective storage faces of interlockingly engaged modules 1 and 5.
  • Each spacer has a midpoint defined on the catch path that shares a radius with a midpoint of a catch member defined on the latch path.
  • the spacers are spaced apart on the spacer path by a separation greater than the arcuate length of a single spacer.
  • Gap 22 is conveniently used for retaining an end of an elongate material to facilitate spooling of that material inside channel 7. Additionally, gap 22 allows some leeway for imperfections in manufacturing, such that slight manufacturing imperfections are less likely to prohibit interengagement of opposed modules.
  • face 3 is substantially planar to provide a channel 7 of substantially constant width dimension 21 given that faces 3 of interlockingly engaged modules have substantially parallel planes.
  • a non- plaiiar face 3 is used to provide a channel 7 having a varying width dimension.
  • base 3 is a downwardly diverging conical frustum such that the dimension 21 of channel 7 progressively outwardly increases.
  • Width dimension 21 is typically preselected on the basis of the width of a material that is to be spooled. A 5% to 10% width allowance is typically applied to facilitate low friction spooling.
  • Base 3 includes a substantially planar support face 12 oppositely directed with respect to face 3.
  • Face 12 defines the outermost lower surface of module 1 both prior to and following formation of device 6. That is, components of formation 4 do not extend beyond the face 12 of module 5 upon interlocking engagement.
  • devices 6 are in some embodiments stacked on top of each other for transport.
  • a planar face 12 facilitates this and reduces the risk of small components of formation 4 being damaged and/or modules 1 and 5 becoming inadvertently separated. It will be recognised that face 12 is not perfectly planar.
  • it includes a protruding webbed formation 54, which is provided to increase structural rigidity of base 3 while reducing the amount of material required.
  • the webbed formation is defined by an outer ring 55 and concentric inner ring 56 connected by a plurality of radially extending ribs 57. Although the webbed formation is not perfectly flush with the remainder of the support face, the support face is nevertheless regarded as substantially planar for the purposes of this disclosure.
  • Each latch 15 includes a stem 30 extending from path 18 and having an arcuate cross section.
  • a head portion 31 outwardly protrudes from stem 30 and is spaced apart from the face 3.
  • This head portion includes a downwardly facing abutment surface 33 that is substantially parallel to face 3.
  • Each catch 16 includes a bacldng wall 35 upwardly extending from path 19.
  • a downwardly facing abutment lip 36 inwardly projects from wall 35 for abutting engagement with surface 33 upon interlocking engagement.
  • Lip 36 is also substantially parallel to the plane of the storage face, and as such is substantially parallel to abutment surface 33.
  • Each catch further includes a pair of opposed sidewalls 37 extending between respective side edges 38 of wall 35, lip 36, and face 3 to thereby restrict relative rotational movement of interlockingly engaged modules.
  • Each head portion 31 includes a downwardly outwardly extending guide surface 40.
  • Latch 15 subsequently resiliency returns to its resting position to mutually oppose lip 36 with respect to the surface 33 and thereby provide the interlocking engagement between catch 15 and a latch 16.
  • Each catch member includes a director surface 41 profiled for close conformity with surface 40 during the temporary cantilevering. It will be appreciated that this reduces surface friction and thereby reduces the level of force required to bring two opposed modules into interlocking engagement.
  • Spacers 17 include respective substantially planar upper surfaces 43. The vertical displacement of surfaces 43 with respect to surface 3 substantially equals the vertical displacement of surface 33 with respect to surface 3. It will be appreciated that this locks modules 1 and 5 into a fixed predetermined axial separation and preserves dimension 21. Given that both relative axial and rotational movement between interlocked modules 1 and 5 is substantially prevented, device 6 has a relatively solid feel. That is, device 6 feels like a single component as opposed to two distinct components held loosely together.
  • latches 15, catches 16 and spacers 17 are integrally formed from a resilient plastics material.
  • this material includes either or both of reground polystyrene or reground polyethylene. It will be appreciated that such selections are typically made to contain unit costs. That being said, a selected material typically has a sufficient degree of resilience to allow resiliently biased cantilevering of latch 15 to allow the above-described interlocking engagement. Further, a selected material is typically not be so brittle as to allow breakage of components of formation 4 upon slight force. In some embodiments non- plastic materials such as metals are used, however an increase in production cost is inherent, particularly on the basis of a comparison with the low unit production cost of plastic moulding given an appropriately constructed mould.
  • FIGS. 9 and 10 illustrate a module 1 onto which an elongate conductor 23 is spooled. In the illustrated example three individual like side-by-side-conductors define conductor 23. Such conductors are disclosed in US patent application no. 10/539655. The disclosure herein relating to spooling of the particular described conductor
  • device 6 is particularly well adapted for situations where there exists a desire to spool materials in a controlled manner, and for situations where it is preferred to carry out spooling whilst the storage channel is open thereby allowing convenient longitudinal access.
  • Conductor 23 includes a first side 24 and a second side 25. To spool conductor 23, a bend towards side 24 is made at a leading end 26. End 26 is placed in gap 22 such that side 24 of end 26 is abutted against an edge 27 of spacer 17 for retention in gap 22. Conductor 23 is then wound in a clockwise direction as a spiral outwardly extending form spacer path 20. It will be appreciated that where side 24 of end 26 is instead abutted against the opposite edge of spacer 17, conductor 23 is wound in an anti-clockwise direction. For optimal storage capacity, winding progresses such that upon each revolution a region of side 24 contacts with a preceding region of side 25. Winding continues until any one or more of the following occur:
  • a predetermined quantity of conductor 23 has been spooled. • The spiral of conductor 23 extends to the radial periphery of base 3.
  • the three individual conductors defining conductor 23 are individually spooled one at a time using the above-described method. That is, a first conductor is bent and abutted against an edge 27 of spacer 17 for retention in gap 22, and subsequently then wound in a clockwise (or alternately anticlockwise) direction as a spiral outwardly extending form spacer path 20 and adjacent face 3. A second conductor is then similarly bent, abutted and wound adjacent the first conductor, and the third conductor similarly adjacent the second conductor. In some embodiments alternate arrangements are made to retain end 26 with respect to gap 22.
  • module 1 is interlockingly engaged with module 5 to form device 6 and retain the spooled conductor 23 within channel 7.
  • spooled conductor 23 is resiliently biased towards a linear configuration and, as such, will inherently attempt to outwardly unravel.
  • a retainer is used to reduce the risk of this occurring.
  • this retainer is relatively rudimentary, such as a portion of adhesive tape interconnecting an end 70 of conductor 23 to an adjacent underlying region of side 25.
  • Figures 11 to 14 illustrate a more sophisticated locking clip 71 for use with a suitably adapted variation of module 1 having a castellated periphery. This clip 71 defines a barrier about the opening of channel 7 such that conductor 23 is substantially radially retained within the channel.
  • Clip 71 is releasably engageable with adjacent peripheral portions 72 of interlocked modules 1 and 5.
  • Clip 71 includes a pair of end portions 73 and 74 interconnected by a central web portion 75.
  • Clip 71 is preferably axially symmetrical about the midpoint of the central web 75.
  • Each end portion defines a locking channel 76 engageable with portions 72. More specifically, contiguous inner, outer, end and locking flanges - numbered 77 to 80 respectively - define the locking channel.
  • Flange 80 is snap lockingly engageable with module 1 or 5.
  • Each portion 72 includes an anchor block 81 for lockingly receiving channel 76 and an anchor slot 82 radially inwardly adjacent the anchor block for receiving flange 80.
  • These anchor blocks are axially recessed such that flange 79 sits substantially flush with the axially outermost periphery of module 1 or 5. Further, the anchor blocks are radially recessed such that flange 78 sits substantially flush with the radially outermost periphery of the module.
  • clip 71 substantially prevents inadvertent outward unravelling of conductor 23 beyond the outermost radial periphery of device 6. Further, and as a result of the radial and axial recessing, there is a low risk of these clips becoming damaged or accidentally released during transport.
  • Clip 71 protects device 6 and conductor 23 from compression induced damage.
  • spacers 17 maintain a threshold separation between modules 1 and 5 about path 20, pressure on either of faces 12 creates a risk of compression-induced damage to conductor 23 and/or formation 4 about the radial periphery of device 6.
  • Outer flange 78 is recessed radially such that flanges 77 abut respectively with the opposed faces 3 of modules 1 and 5. This maintains a threshold separation between these faces at the periphery of the respective bases, as best shown in Figure 14. It will be appreciated that this reduces the risk of such compression-induced damage.
  • one flange 80 is placed adjacent a slot 82 on module 5, as shown in Figure 12. End portion 74 is then pushed inwards to bring the other flange 80 into locking engagement with module 1.
  • Clip 201 is similar to clip 71, however includes some design modifications.
  • the web portion 75 includes a pair of peripheral ribs 202 for providing increased structural rigidity and resiliance to the clip.
  • an aperture 203 is formed through each end portion 73 and 74. This aperture performs a dual purpose of allowing convenient formation of flange 80 and facilitating the removal of the clips at an appropriate time.
  • clips such as clips 71 or 201 are most useful when device 6 is fully spooled such that conductor 23 is proximal the interior faces of the clips. However, upon partial unspooling, the clips are less efficient in preventing unwinding of conductor 23.
  • a plurality of radially elongate apertures 204 are provided through base 2. These apertures are circumferentially spaced apart on a plurality of radially spaced concentric paths 205 such that upon formation of device 6 apertures on modules 1 and 5 are substantially aligned. This allows a retention device, such as a conventional cable-tie, to be inserted through aligned apertures for the purpose of conductor retention.
  • One or more pairs of aligned apertures 204 on a concentric path 205 of radius generally corresponding to the extent of conductor spooling are selected.
  • a cable-tie is passed through each of these one or more pairs to substantially secure the conductor in the desired wound configuration.
  • the cable ties are subsequently severed and removed to allow further unspooling and, where this further unspooling is again partial unspooling, the process repeated using apertures 204, often on a radially inner path 205 compared to those used previously.
  • one of spacers 17 is a start spacer 29 including a unique marker for identifying a spool start position.
  • this marker is a physical formation 27 on the start spacer.

  • a measurement display is provided for indicating an approximate spooled length of conductor 23.
  • This display is presently in the form of an array of marking apertures 50 formed through base 3.
  • Face 12 includes length markers 51 adjacent the apertures 50 to mark specific lengths.
  • a marker 51 denotes a length "A". Where a spooled spiral of conductor 23 passes the aperture 50 adjacent that marker 51, it is known that the approximate spooled length of conductor 23 is A.
  • markers 51 it is typically necessary to factor in the width of conductor 23. This width determines the rate of outward progression of a spool spiral. Alternately, a measured length of conductor 23 is spooled on a stencil module to reactively identify lengths for marking on subsequent modules. It will be appreciated that markers 51 are only effective for a particular size and configuration of conductor 23. Other considerations apply - such as setting a standard bend length for end 26. Those skilled in the art will readily recognise and apply these to a particular scenario. To use the spooled conductor, typically an axle is inserted through a central aperture 89 of base 3 such that device 6 is rotatable. Conductor 23 is then pulled, and continuously progressively extends as device 6 rotates. Many other conventional spool release techniques are readily alternatively applied.
  • base 3 For each latch 15, base 3 includes an adjacent latch aperture 90 having an inner edge 91 defined by an outer edge 92 of the relevant stem 30. For a given latch, the adjacent latch aperture allows moulding of outer surfaces of the latch member. Similarly, for each catch 16, base 3 includes an adjacent catch aperture 93 having an outer edge 94 defined by an inner edge 95 of the relevant backing wall 35. Those skilled in the art of plastic moulding will understand how apertures 90 and 94 are used to facilitate moulding and/or pressing of surfaces of the catches and latches. Apertures 90 and 94 are also used to allow disengagement of modules 1 and 5.
  • a purpose built jig is insertable to either or both of the latch apertures and the catch apertures. This jig is used to move the latch members against the resilient bias and bring the abutment surfaces 33 out of engagement with the abutment lips 36 sucli that modules 1 and 5 are axially separable. Whilst an appropriate jig is not shown, those skilled in the art will recognise how one is reversed engineered on the basis of the configuration of modules 1 and 5.
