This application is a National Stage Application of PCT/EP2009/001487, filed 3 Mar. 2009, which claims benefit of Serial No. 2008902701, filed 29 May 2008 in Australia and which applications are incorporated herein by reference. To the extent appropriate, a claim of priority is made to each of the above disclosed applications.
The present invention relates to an assembly for dispensing telecommunications cable from a reel.
A number of systems have been developed for packaging and dispensing wound flexible media, such as telecommunications cable. For example, current packaging includes a cardboard box with internal plastic supports for rotatably mounting a reel of cable. A difficulty with the cardboard packaging is that is may not be sufficiently strong to permit palletisation and support the weight of the same product stacked on top of it. Further, the packaging may not lend itself to easy handling and maneuvering in environments with limited space, for example.
Cardboard cartons permit cable to be removed from the front of the box, for example. However, the cardboard packaging does not typically permit the reel to be viewed as cable is being dispensed and, consequently, the operator may not be able to see how the cable is feeding off the reel. Further, existing cardboard packages have limitations particularly when it is desirable to draw cable from multiple packages. In an installation where bundles of up to 12 cables are being installed, for example, the cartons are typically stacked in a 3×4 configuration and can be quite unstable when the cable is pulled. Due to the nature of the product and the regular surface of the cardboard, extra means are usually needed to make the stack of reels stable.
Other dispensing systems have been developed with a view to overcoming the above described difficulties. For example, with reference to FIG. 1, U.S. Pat. No. 6,523,777 teaches a portable wire spool caddy that includes a frame (12) with end plates (14, 16) separated by rectangular supporting members (18, 20). The caddy is shaped to house a reel (42) between the support members (18, 20) and the plates (14, 16) in a manner that permits the reel (42) to spin as cable is drawn therefrom. The caddy also includes a swing (80) and bracket (54) which is adapted to bear against the reel (42) and function as a braking mechanism. The wire spool caddy taught by U.S. Pat. No. 6,523,777 may provide a useful device for generally dispensing cable. However, the wire spool caddy may not provide a tie-off mechanism for securing an end of the cable with respect to the caddy. Further, U.S. Pat. No. 6,523,777 may not provide a mechanism that can tie-off an end of the cable and stop the reel (42) from rotating due to inertia during transportation.
Similarly, U.S. Pat. No. 5,967,451 teaches a carrier for carrying one or more wire spools. With reference to FIG. 1 of U.S. Pat. No. 5,967,451, the carrier includes end plates (26, 28) connected by a central rod (20), connecting rods (48, 50) and handle (46). The carrier includes a semicircular cradle (24) arranged to support the wire spools (12, 14) and to protect them from “free wheeling” in which the spools continue to spin after the user has ceased pulling the wire from the spools. The cradle (24) includes a number of slots (36), one for each spool, through which wire is drawn from the spools (12, 14). The cradle taught by U.S. Pat. No. 5,967,451 may provide a useful device for generally dispensing cable. However, the cradle may not provide a tie-off mechanism for securing an end of the cable with respect to the cradle. Further, U.S. Pat. No. 5,967,451 may not provide a mechanism that can stop the wire spool (12, 14) from rotating due to inertia during transportation.
It is generally desirable to overcome or ameliorate one or more of the above mentioned difficulties, or at least provide a useful alternative.
In accordance with one aspect of the invention, there is provided an assembly for dispensing telecommunications cable from a reel, including:
Preferably, the assembly includes a brake coupled to the first end member of said end members, wherein the brake is adapted to receive a section of the cable and inhibit movement of the section of the cable with respect to the first end member.
Preferably, the brake defines a slot adapted to receive and resiliently bear against a lateral section of cable so as to inhibit longitudinal movement of said lateral section of the cable with respect to the first end member.
Preferably, the brake at least partially elastically deforms as the lateral section of the cable is received in the slot and thereby resiliently bears against the reel to inhibit rotation of the reel about the axle.
Preferably, the slot is defined between a convex section of the brake seated at least partially within a corresponding concave section of the brake.
Preferably, the convex section is adapted to move relative to the concave section as the lateral section of the cable is forced into the slot.
Preferably, the convex section is adapted to resiliently bear against the reel coupled to the axle during said relative movement to inhibit rotation of the reel about the axle.
Preferably, the convex section includes a boss shaped to engage corresponding grooves of the reel during said relative movement to inhibit rotation of the reel about the axle.
Preferably, the brake is formed integrally with a generally planar section of the first end member.
Advantageously, preferred embodiments of the invention provide a robust assembly for packaging and dispensing telecommunications cable that permits palletisation.
Advantageously, preferred embodiments of the invention provide a useful assembly for dispensing telecommunications cable, for example. Further, preferred embodiments of the invention advantageously provide an assembly which operates to tie off end sections of cable. Further still, preferred embodiments of the invention advantageously operate to prevent a reel from rotating about an axle when the cable has been tied off.
Preferred embodiments of the present invention are hereafter described, by way of non-limiting example only, with reference to the accompanying drawings in which:
The assembly 10 sown in
The assembly 10 is adapted to function as robust packaging for the reel of cable 12. The assembly 10 is strong enough to permit palletisation. The brake 24 of the assembly 10 operates to tie off end sections of cable 12. The brake also operates to prevent the reel 14 from rotating about the axle 22 when the cable 12 has been tied off.
In the example shown, the end members 16, 18 are generally planar square plates that permit uniform stacking in different orientations. The assembly 10 includes four elongate cross-members 20a, 20b, 20c, 20d and the axle 22 is formed in two parts 22a, 22b, each extending normally away from central sections of respective opposed sides of the end members 16, 18. The reel 14 is be supported between the two parts 22a, 22b of the axle 22 and adapted to rotate freely there around. As illustrated, the assembly 10 includes four brakes 24a, 24b, 24c, 24d operatively coupled to respective corners 26a, 26b, 26c, 26d of the end members 16, 18. The brakes 24a, 24b, 24c, 24d operate independently to tie off end sections of cable 12. The brakes 24a, 24b, 24c, 24d also independently operate to prevent the reel 14 from rotating about the axle 22 when the cable 12 has been tied off.
As particularly shown in
As particularly shown in
The inner peripheral surface of each aperture 40 includes a slot 44 shaped to receive a lever, such as the spade of a screw driver, to assist in urging the end sections 42 out of corresponding apertures 40.
The hollow cross-members 20a, 20b, 20c, 20d of the assembly are adapted to receive string or rope there through to tie a stack of assemblies 10 together.
The cross-members 20a, 20b, 20c, 20d are sufficiently strong and are of suitable dimensions to function as handles. The end members 16, 18 are sufficiently strong and rigid to allow the assembly 10 to be palletised and support the weight of the same assembly 10 stacked on top of it.
The end members 16, 18 each include predetermined areas 46 adapted to bear indicia for labelling the assembly 10. The predetermined areas 46 preferably can be written on with a felt tipped pen or ballpoint pen, for example. Alternatively, the predetermined areas 46 are adapted to receive a sticker, for example, bearing indicia for labelling the assembly 10.
As particularly shown in
The brake 24 also defines a slot 54 adapted to receive and resiliently bear against a lateral section of cable so as to inhibit longitudinal movement of said lateral section of the cable 12 with respect to the end member 16, 18. Further, the brake 24 at least partially elastically deforms as the lateral section of the cable 12 is received in the slot 54 and thereby resiliently bears against the reel 14 to inhibit rotation of the reel 14 about the axle 22. The slot 54 preferably opens into the aperture 50 so that a longitudinal section of cable threaded through the aperture can be forced into the slot 54. Alternatively, the slot 54 opens into the top of the end member 16, 18 so that a longitudinal section of cable threaded through the aperture can be forced into the slot 54.
The slot 54 is defined between a convex section 56 of the brake 24 seated at least partially within a corresponding concave section 58 of the brake 24. The convex section 56 is adapted to deform and move relative to the concave section 58 as the lateral section of the cable 12 is forced into the slot 54. As particularly shown in
The brake 24 is preferably formed integrally with a generally planar section of the end member 16, 18.
As particularly shown in
The above described arrangement of the assembly 10 allows for cable 12 to be pulled out from the top reel over a cross-member 20. Cable 12 can thereby be dispensed in various orientations to suit the space available. As particularly shown in
Unlike cardboard box based dispensing systems, the assembly 10 supports the reel 14 in a manner that provides clearance between cross-members 20. As such, a stack can be arranged in a lower and longer arrangement due to increased stability. A combination of stacking orientations, as shown in
As particularly shown in
A stack of assemblies 10 can be further stabilised by tying the stack together by threading string, for example, through the hollow cross-members 20. The axle 22 is preferably hollow so that the stack of assemblies can be further stabilised by threading a rope or water pipe through adjacent hollow axles.
