Definitions

  • the present invention relates to a cable reel, and a cable reel in combination with a coil of cable. More particularly, the present invention relates to a cable reel wherein first and second flanges may be removed from a hub, and the hub may be disassembled into at least two parts, so that the disassembled reel may be conveniently stored and shipped.
  • Some prior art reels have one of the flanges being removeable so that a new coil of cable may be loaded around the hub and rest on the remaining flange before the removed flange is reinstalled onto the hub.
  • Some prior reels have many hinges and locking features located around a midportion of the hub, so that the hub may be folded or collapsed onto itself to bring the flanges closer together after a coil of cable has been completely paid off from the reel.
  • Some prior art reels are made with multiple piece hubs and flanges which snap together, but are typically made to be assembled and not disassembled. The snap together fasteners are not made to be repeatedly unmated and remated.
  • the snap together reels of the prior art tend to have numerous locking features which adds to the costs and complexity of the reel.
  • Cable is commonly shipped to a customer on a reel.
  • the reel is typically formed of plastic. It is important to recycle or reuse the plastic reel after all the cable has been paid off from the reel in order to be “green” and not send massive numbers of plastic reels as trash to landfills. Recycling the plastic material takes energy, time and storage space.
  • the reels would be crushed/broken into a compacted state and stored in a bin until a truck load of crushed reels is accumulated.
  • the plastic material pieces are then transported to a recycling center and energy is again expended to transform the crushed plastic pieces into new raw plastic material, e.g., pellets, to be used to form a new and potentially different product.
  • Reusing the reels is a “greener” option than recycling, as the energy used to transform the crushed pieces of plastic material into pellets for reuse is avoided.
  • the empty reels take up considerable customer floor space as they are accumulated.
  • shipping the empty reels from the customer to the manufacturer is costly, as the empty reels are not compact, e.g., the areas within the hub and between the flanges are empty air.
  • a box full of empty reels is large in dimensions, yet light weight as only a few empty reels will fill the box, and the volume of the box is mostly air.
  • the prior art reels with a single removable flange provide only limited improvement in reducing the bulky nature of the empty reels.
  • the center hub is still intact and occupied by air.
  • the empty reels are expensive to return to the manufacturer.
  • the prior art reels with the folding hub like US Patent 5,649,677 do result in a very compacted empty reel.
  • the folding hub designs have many moving parts and are expensive to manufacture, noting the reel in US Patent 5,649,677 includes eleven plastic hub pieces with thirty-three hinges to allow the hub to fold flat onto itself.
  • the customer tends to toss the empty reel into the collection bin, the impacts to the collapsed reel tend to break one or more of the thirty -three hinges. If even one hinge is broken, the reel will typically not be reloaded with cable by the manufacturer because the reel could be unstable and dangerous to the manufacturing personnel in conjunction with high-speed cable reloading equipment. Often the entire reel will be recycled, especially if the labor cost of a repair exceeds the reel replacement cost.
  • the reel of the present invention allows for a cheaper/lower cost construction of a reel, which can be made compact for the purposes of shipping the reel parts back to the cable manufacturer for reloading of the reels.

  • a single shaft may pass through the central openings 35 to provide an axis of rotation when the cable reel 11 is being loaded with a coil of cable 39 (Figure 13) during a manufacturing step, e.g., to wind cable 39 about the hub 19 and between the first and second flanges 13 and 27, and/or when cable 39 is being paid off the cable reel 11 by a customer.
  • spaced spindles may be inserted into the central openings 35 from the second sides 17 and 31 of the first and second flanges 13 and 27, respectively, to allow for supported rotation of the cable reel 11.
  • FIG 4 is a top perspective view of the second side 17 of the first flange 13 of the cable reel 11, disconnected from a hub 19.
  • Figure 4 shows four empty slots 41 passing through the first flange 13.
  • the slots 41 form a part of the first twist on / twist off arrangement 25.
  • each slot 41 is arcuate and includes a wide portion 43 and a narrow portion 45.
  • Each slot 41 covers an arc of about sixty degrees, leaving an arc of about thirty degrees between adjacent slots 41.
  • the second side 17 of the first flange 13 also includes four locking openings 47, with each locking opening 47 being adjacent to a narrow portion 45 of a slot 41.
  • the locking openings 47 may pass entirely through the first flange 13 or be mere depressions formed into the second surface 17 of the first flange 13.

  • Figure 5 is a front perspective view of the first part 49, which forms a half of the tubular cylindrical shape of the hub 19.
  • Figure 6 is a front view of a second part 51, which forms a half of the hub 19, i.e., the other half of the tubular cylindrical shape.
  • the first part 49 of the hub 19 has a first side edge 53 with a first channel 55 formed therein and an opposite, second side edge 57 with a first tongue 59 extending therefrom.
  • the first side edge 53 is connected to the second side edge 57 by a first portion of the first end 21 of the hub 19 at a top of the first part 49 and by a first portion of the second end 23 of the hub 19 at a bottom of the first part 49.
  • the second part 51 of the hub 19 has a first side edge 61 with a second channel 63 formed therein and an opposite, second side edge 65 with a second tongue 67 extending therefrom.
  • the first side edge 61 is connected to the second side edge 65 by a second portion of the first end 21 of the hub 19 at a top of the second part 51 and by a second portion of the second end 23 of the hub 19 at a bottom of the second part 51.
  • the first and second channels 55 and 63 are rectangular in cross-sectional shape and recessed into the first side edges 53 and 61 of the first and second parts 49 and 51.

  • the first biasing tab 69 is formed in a sidewall of the first tongue 59 of the first part 49 and protrudes away from the sidewall of the first tongue 59 and creates an added frictional force to hold the first tongue 59 of the first part 49 within the second channel 63 of the second part 51.
  • the second biasing tab 71 is formed in a sidewall of the second tongue 67 of the second part 51 and protrudes away from the sidewall of the second tongue 67 and creates an added frictional force to hold the second tongue 67 of the second part 51 within the first channel 55 of the first part 49.
  • the first and second biasing tabs 69 and 71 need not be formed in a sidewall of the first and second tongues 59 and 67, but could instead be formed in the sidewalls of the first and second channels 55 and 63 and protrude inwardly toward centers of the first and second channels 55 and 63.
  • the first and second parts 49 and 51 of the hub 19 may be formed substantially identically, e.g., by a common plastic molding operation.

  • the second portion 77 of the locking tab 73 may pass through the wide portion 43 of the slot 41. As the first flange 13 is rotated in a first direction relative to the hub 19, the first portion 75 of the locking tab 73 passes into the narrow portion 45 of the slot 41 and the second portion 77 of the locking tab 73 overlies the second side 17 of the first flange 13 adjacent to the narrow portion 45 of the slot 41.

  • the first and second tongues 59’ and 67’ of the first and second parts 49’ and 5 are bulbous in a cross- sectional shape, so as to mate into the first and second channels 55’ and 63’ by siding laterally into the first and second channels 55’ and 63’.
  • Figure 14 is similar to Figure 5 but illustrates three alternative and/or optional features of the present invention.
  • reinforcement ridges 37 may optionally be included on an inside wall 101 of a modified, first part 49 A.
  • the reinforcement ridges 37 may extend out about 2 mm from the inside wall 101 and will improve the rigidity and durability of the modified, first part 49A.
  • a modified, second part 51 A of the hub 19 may be formed substantially identically to the modified, first part 49A, e.g., by a common plastic molding operation. Therefore, the three alternatives being described herein apply equally to the modified, second part 51 A.
  • the modified, first part 49A still includes the first side edge 53 with the first channel 55 formed therein and the opposite, second side edge 57 with the first tongue 59 extending therefrom.
