Abstract
Description
- This invention relates to an apparatus for storage and transportation of elongate coilable members such as tubing, cables and the like.
- In particular, the invention is concerned with a demountable cable reel.
- Timber cable reels are well known but the majority of these are expensive to construct in terms of labour content and due to their shape and size, there is a high cost of transportation to a cable manufacturer in the first instance and subsequently when being returned for rewinding. Moreover, empty reels are prone to damage during storage and transportation.
- To reduce shipping and storage costs of empty cable reels, it has been proposed to provide a demountable reel where the generally circular end flanges are removable from the spool, and in some cases the spool itself is demountable to a more compact shape. Many of these demountable cable reels rely upon elongate bolts extending via the hollow interior of the spool between opposed flanges for their structural integrity when wound with cable or the like.
- Demountable cable reels which rely primarily for structural integrity in an assembled state only on bolts extending between opposed flanges are described in U.S. Pat. No. 2,652,992, U.S. Pat. No. 1,767,710, U.S. Pat. No. 1,915,825, U.S. Pat. No. 2,266,903, German Patent DE 2439488, European Patent Application EP 1987000401297 (Publication No. EP 250295) and U.S. Pat. No. 5,588,628.
- French Patent Application 88 04881 describes a demountable cable reel wherein structural integrity in an assembled state relies partially upon bolts extending between opposed flanges and partially upon interengagement between spool elements and the opposed flanges.
- European Patent Application 91121835.2 (Publication No. 0491400 A1) describes a demountable cable reel having core elements bolted at opposite ends to the opposed end flanges.
- Demountable cable reels having foldable core elements and/or flange elements are described in U.S. Pat. No. 5,409,179, U.S. Pat. No. 5,467,939, European Patent Application 94401537.9 (Publication No. EP 0636567 A1) and British Patent 1170714.
- U.S. Pat. No. 5,464,171 describes a demountable cable reel where integrally formed flange/spool members interconnect intermediate the ends of the spool.
- International Patent Application No. PCT/US97/13809 (Publication No. WO 96/06654) describes a spool comprised of a plurality of interlocking elements.
- In the interest of both cost and convenience, there is a requirement for a simple demountable cable reel with integral locking or fastening means to avoid the need for separate fasteners such as bolts or the like which are easily lost in transit.
- Australian Patent 442191 describes a cable reel comprising a pair of circular end flanges, each with an array or radial slots spaced about a central shaft aperture. Core elements comprising a disc like member with radially extending arms which are insertable through the slots of a respective flange for connection with corresponding arms of a core element extending through an opposite flange. A cylindrical spool acts as a spacer to keep the flanges apart.
- Other demountable cable reels having circular end flanges and non-demountable cylindrical spools are described in U.S. Pat. Nos. 5,868,348, 5,743,486, 5,242,129, 5,660,354 and 5,727,752.
- Demountable cable reels having planar flanges and demountable or collapsible spools but otherwise with integral connecting means are described in Australian Patent 224780, British Patent GB 2269157. Australian Patent 592112, U.S. Pat. No. 5,806,788 and Australian Patent 678296.
- Although the last mentioned group of prior art cable reels has some advantages over the previously mentioned prior art cable reels, each suffers one or more practical shortcomings in use.
- For example, the cable reels of British Patent 2269157, Australian Patent 592112, Australian Patent 442191 and Australian Patent 224780 are not considered sufficiently robust for larger capacity cables.
- While the cable reels of U.S. Pat. No. 5,806,788 and Australian Patent 678296 are better suited to more robust duty, each suffers the disadvantage that in order to replace a flange damaged in handling or transportation, the reel must first be emptied of cable which is time consuming and inconvenient.
- With a move by cable manufacturers towards moulded plastics demountable cable reels of ever increasing capacity, it is not uncommon for an end flange to be damaged due to rough handling or insecure shipping.
- In the event of damage to a flange on a fully wound cable reel, there is a need to be able to replace that flange without the need to first remove the cable and then to rewind the cable onto the repaired reel as remote site reel repairs may be carried out without having to return the loaded reel to the cable manufacturer.
- It is an aim of the present invention to overcome or ameliorate at least some of the shortcomings associated with prior art cable reels and otherwise to provide users with a convenient choice.
- According to one aspect of the invention there is provided a demountable reel for elongate coilable objects, said reel comprising:
- a pair of end flanges, said end flanges each including an inwardly facing spool connecting boss;
- a generally cylindrical spool comprising two or more spool elements, each said spool connecting boss and said spool being engagable by axial alignment of complementary engagement members and releasably selectable by axial misalignment between said complementary engagement means, said reel being characterised in that an end flange may be removably replaced by a substitute end flange with an elongate object coiled in situ about said spool.
- Suitably each said end flange includes reinforcement means adjacent a perimetral rim member.
- If required said spool connecting boss may be recessed below an inner face of said flange.
- Preferably said spool connecting boss projects outwardly from an inner face of said flange.
- Suitably said boss includes a central shaft aperture.
- If required each said flange may include a plurality of radially spaced apertures to locate, in use, tensionable members extending between opposed flanges.
- Suitably said radially spaced apertures include reinforcing means.
- If required said spool may comprise two or more separate elements releasably connectable adjacent transverse edges to form a cylindrical spool.
- Alternatively said spool may comprise two or more spool elements with an integrally formed hinge joint, said two or more spool elements being movable between an extended storage and/or transportation position and a contracted position forming a cylindrical spool.
- If required said spool elements may include axially extending reinforcing members. Additionally or alternatively said elements may include radially extending reinforcing elements.
- Preferably said reinforcing elements are integrally formed adjacent an inner surface of said spools elements.
- Said spool elements preferably comprise shouldered end portions.
- Suitably, said complementary engagement members associated with said flanges comprise a plurality of circumferentially spaced radially oriented projections and/or recesses on said boss.
- The complementary engagement means associated with said spool elements comprise circumferentially spaced radially oriented projections and/or recesses in said shouldered end portions.
- The spool and respective flanges may be releasably secured by engagement of projections on said boss behind projections on said spool by at least partial relative rotation between said flanges and said spool.
- Suitably at least one cam member is provided to wedgingly engage said spool with respective end flanges.
- If required said cam member may be operative in a radial direction.
- Suitably stop means is provided to limit relative rotation between said spool and respective flanges.
- Preferably, releasable locking means is provided to prevent disengagement between said spool and a respective flange.
- Suitably said locking means is adapted to prevent relative rotation between said spool and a respective flange when said complementary engagement means are engaged.
- Most preferably, said locking means is actuable from an exterior region of each said flange.

- In FIG. 1
spool elements 1, 2 have a keyed rib 3 on one edge and a complimentary keyhole slottedaperture 4 on an opposite edge to enable a cylindrical spool to be assembled from four identical elements by slidable engagement of a rib 3 of one element with the slottedaperture 4 of an adjacent element. - Each spool element has a smooth arcuate
outer surface 5 andarcuate end walls 6 comprising a series of alternately spacedtooth 7 andapertures 8. - FIGS. 2 and 3 show alternative embodiments of an
end flange 9 having aspool supporting boss 10 and acentral shaft aperture 11. - In FIG. 2, the
boss 10 is located in arecess 12 a ininner flange wall 12 whereas in FIG. 3, theboss 10 sits proud ofinner flange wall 12. - In both cases,
boss 10 comprises acylindrical base 13 with a spaced array ofteeth 7 a extending radially from the outer end ofbase 13 to form a recessed region betweenteeth 7 andflange wall 12. - FIG. 4 shows schematically the engagement of a
cylindrical spool 14, formed from the elements shown in FIG. 1 and theboss 10 of theflange 9 shown in either of FIG. 2 or FIG. 3. - As can be seen, when the
teeth 7 a ofboss 10 are aligned withapertures 8 of the end wall ofspool 14 and similarly theapertures 8 a ofboss 10 are aligned withteeth 7 of the end wall ofspool 14, the complementary shapes of the respective teeth and apertures enables, thespool 14 to engage overboss 10. -
Apertures 15 are optionally provided inteeth 7 a, the purpose of which apertures 15 will be described later. - FIG. 5 shows an exploded view of a cable reel
assembly comprising spool 14 assembled from the elements shown in FIG. 1 and the flanges of FIG. 3. - After the respective teeth and apertures of the spool end walls and the flange are aligned and the
teeth 7 a offlange 9 are located withinapertures 8 of thespool end wall 6, theflange 9 is partially rotated relative to spool 14 such thatteeth 7 a offlange 9 are located behindteeth 7 ofspool 14, thereby removably securing theflange 9 to spool 14. - FIG. 6 is a part cross sectional view of the securement of
flange 9 of FIG. 3 to spool 14. - FIG. 7 is a part cross sectional view of the securement of
flange 9 of FIG. 2 to spool 14. - FIG. 8 is a plan view of the assembly shown in FIG. 6 with the

Apertures - FIG. 9 shows an alternative form of connection for spool elements.
- As shown, one
edge 20 ofspool element 21 is formed with a V-shapedchannel 27 having spacedapertures 22 therein. - The
opposite edge 23 is formed with a complementary V-shapedrib 24 havingpins 25 with enlarged deformable heads 26 thereon. - As can be seen, when the respective adjacent edges of
spool elements 21 are brought together, the initial engagement betweenchannel 27 andrib 24 guides the headed pins 25 into alignment withrespective apertures 22. When fully engaged therib 24 andchannel 27 reinforce the connection between theedges - FIG. 10 shows an alternative means of connecting spool elements.
- In this embodiment, opposed edges of each spool element28 are formed with
alignable abutments abutment 29 having a slottedrecess 31 and the other having a barbeddeformable pin 32 for engagement therein. - FIG. 11 shows a modification to the embodiment of FIG. 1.
- In this embodiment, short keyed
ribs 35 on one edge of aspool element 36 are adapted for insertion intocorresponding keyhole slots 37 of an adjacent spool element. Theshort keyhole slots 37 permit resilient deformation to receive thekeyed ribs 35 when pushed together in a generally tangential direction. - Located between
keyed ribs 35 are one or more slottedapertures 38 to receive one ormore tongues 39 which assist in alignment and reinforcement of the edges when assembled. - FIGS. 12, 12a and 12 b shows yet another means of connecting spool elements.
- In this embodiment one
edge 40 of aspool element 41 is provided with spacedapertures 42 to receive deformable head pins 43 mounted on an integrally hingedflap 44 of anadjacent spool element 41. - On the inner side of

pins 43 are located in a recess 17 formed betweeninclined edge 48 ofspool element 49 and the integrally hingedflap 50 havingapertures 51 to receive pins 43. - FIG. 12 also shows optional reinforcing
ribs 52 extending axially along theinner wall 53 ofspool element 41 and radially extendingribs 54 also or alternatively extending alonginner wall 53. - FIG. 13 shows schematically a transversely extending reinforcing rib66 extending between
opposed end walls 56 of aspool element 57. - FIG. 14 shows a
steel reinforcing element 60 which may be employed in the flanges of larger capacity cable reels according to the invention. - The reinforcing element comprises a central shaft reinforcing tube61, a plurality of radially spaced
webs 62 and retainingplates 63 for tensionable bolts not shown which extend between opposed reel flanges. - Retaining
plates 63 havekeyhole apertures 64 for ease of inserting and connection of the tensionable bolts. - Suitably, the reinforcing
element 60 is placed into an injection moulding die for the reel flange and is encapsulated in the moulding process. - FIG. 15 shows a port cross sectional view of a reel assembly showing a
flange 70, aspool 71 mounted onflange boss 72 and atensionable steel bolt 73 extending between opposed flanges. - In this view, an alternative embodiment is illustrated in that a
dual diameter boss 72 comprises alarger diameter portion 72 a and asmaller diameter portion 72 b to accommodate a smaller diameter spool if required. - FIG. 16 shows a locking means to prevent disengagement between the end flange and a spool of a cable reel.
- In a radially directed reinforcing
rib 80 offlange 81, there is formed an integrally hingedtab 82 having apin 83 extending from an underside thereof. - In the locked position shown,
tab 82 lies against theouter face 84 offlange 81 withpin 83 extending through anaperture 83 inface 84 and thence into an aligned aperture (not shown) into an end wall portion of a spool (not shown) to prevent relative rotation therebetween when the flange and spool are secured. - FIG. 17 shows a variation in flange design incorporating reinforcing
ribs 90 extending radially betweenboss 91 and theinner wall 92 of arecess 93 inflange 94. - Buttressed
ribs 95 reinforce the region of the join between the floor 96 andside wall 92 ofrecess 93. - In this embodiment reference is made to the spool element51 a of FIG. 12.
- For additional reinforcement of the connection between a spool assembled from
elements 41 a andflange 94 of FIG. 17,cavities 97 are provided in the end walls ofspool elements 41 a to accommodateribs 90 yet allow sufficient relative rotation between the spool and flange for securement. - Additionally
tabs 98, upstanding from the outer surface of the spool initially engage in alignedrecesses 99 when the respective teeth and apertures therebetween of the flange and spool when first engaged. As the flange and spool are secured by relative rotationtherebetween tabs 98 locate within slottedapertures 100 and, by resilient recovery, drop below shoulderededges 101 to form a locking means to prevent accidental disengagement between the spool and flange. The locking tabs are accessible from the outer face of opposed flanges to release the locking means. - FIG. 18 shows a means of reinforcing the outer rims of flanges on larger capacity cable reels.
- In this embodiment, rather than have right angle joints between a
flange wall 102 and theouter rim 103, (and any adjacent circumferential reinforcing ribs) which are prone to damage arising from stress concentration at the right angle joint, therim 103 as shown has oppositely directed gently undulatingribs - It will be appreciated that many modifications and variations may be made to the various embodiments of the invention without departing from the spirit and scope thereof.
