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 a hub diameter may be adjusted to accommodate variance of inner diameters of coils, and a spacing between a first flange and a second flange may be adjusted to accommodate different thicknesses of coils, e.g., lengths of cable.
  • a “radial” thickness of a coil of cable may be viewed as a distance between the inner diameter of the coil and the outer diameter of the coil, whereas the “longitudinal” thickness of a coil is the distance between a first side of the coil and a second side of the coil.
  • the longitudinal thickness of a coil is related to the number of winding of the coil, which form the first layer of the inner diameter and hence may relate to an overall length of the cable forming the coil.
  • a spacing between the first and second flanges must be adjustable.
  • the present invention provides a unique system, whereby the second flange may be removed from the hub to facilitate loading of a new coil of cable upon the hub, and improvements are provided to easily reassemble of the second flange onto the hub and to lock the second flange in various positions along the hub to vary a distance between the first and second flanges.

  • spatially relative terms such as “under”, “below”, “lower”, “over”, “upper”, “lateral”, “left”, “right” and the like, may be used herein for ease of description to describe one element or feature’s relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, elements described as “under” or “beneath” other elements or features would then be oriented “over” the other elements or features. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the descriptors of relative spatial relationships used herein interpreted accordingly.
  • Figures 1 and 2 depict left-side and right-side perspective views of the unassembled parts to form a reel 11 for storing a coil of cable 13, in accordance with the present invention.
  • the reel 11 includes a first generally circular flange 15 having a first side 17 and a second side 19.
  • an outer rim of the first flange 15 is circular, and has a diameter of about 20 to 60 centimeter, such as 30 to 50 centimeters, more preferably about 35 to 45 centimeters.
  • a circular rim is shown the rim may have undulations to reduce its weight.
  • first, second and third elongated members 21, 23 and 25 has a first end 27, 29 and 31, respectively, which is attached to the first flange 15.
  • second ends 33, 35 and 37 of the first, second and third elongated members 21, 23 and 25, respectively, extend away from the first side 17 of the first flange 15.
  • the second ends 33, 35 and 37 preferably include a conical shape.
  • a spacing between the first, second and third elongated members 21, 23 and 25 defines a diameter of a hub of the reel 11. More specifically, the outermost radial edges of the first, second and third elongated members 21, 23 and 25 relative to a center of the first flange 15 define contact edges for a coil of cable 13 placed upon the hub, and hence define the minimum diameter of the coil of cable 13 which will fit onto the reel 11.
  • at least one first end 27, 29 or 31 of the first, second or third elongated members 21, 23 or 25 is adjustable in its attachment to the first flange 15. In a preferred embodiment, each first end 27, 29 and 31 of the first, second and third elongated members 21, 23 and 25 is adjustable in its attachment to the first flange 15.
  • each of the first, second and third elongated members 21, 23 and 25 is formed as a cylindrical rod.
  • Each of the first ends 27, 29 or 31 of each cylindrical rod includes a first threaded portion in the form of a threaded bore hole 39, 41 or 43, respectively, to accept therein a threaded faster in the form of a threaded bolt 45, 47 or 49, respectively, so as to attached the first ends 27, 29 and 31 of each cylindrical rod to the first flange 15.
  • the first flange 15 includes first, second and third slots 51, 53 and 55 to receive shaft portions of the threaded bolts 45, 47 and 49.
  • the second side 19 of the first flange 15 includes indentations 57 (best seen in Figure 5) formed alongside edges of the first, second and third slots 51, 53 and 55 to seat heads of the threaded bolts 45, 47 and 49 at different locations along the first, second and third slots 51, 53 and 55.
  • tall elastic washers 38, 40 and 42 are compressed.
  • the elastic washers 38, 40 and 42 perform dual functions.
  • the elastic washers 38, 40 and 42 allow the first, second and third elongated members 21, 23 and 25 to tilt relative to the first side 17 of the first flange 15 when placed under lateral pressure, while remaining biased by the resiliency of the elastic washers 38, 40 and 42 to return to a perpendicular orientation relative to the first side 17 of the first flange 15.
  • the elastic washers 38, 40 and 42 act as a lock washer to apply an axial pressure tending to keep the threaded bolts 45, 47 and 49 tight in engagement within the threaded bore holes 39, 41 and 43.
  • indicia 59 Adjacent to the indentations 57, indicia 59 may be molded into, or protruding from the second side 19 of the first flange 15.
  • the indicia 59 indicates a diameter dimension for the hub e.g., 262 cm, 269 cm, 276 cm, 283 cm and 290 cm.
  • first, second and third elongated members 21, 23 and 25 are mounted into the first flange 15 with the heads of the first, second and third threaded bolts 45, 47 and 49 residing within the middle indentations 57 labeled “276 cm,” then the first, second and third elongated members 21, 23 and 25 will engage and snuggly receive a coil of cable 13 having an inner diameter of 276 cm or slightly less than 276 cm with deflection due to the elastic washers 38, 40 and 42.
  • a coil of cable 13 of a greater diameter e.g., 282mm
  • the coil of cable 13 will not fit snuggly and will be able to “free spin” about the first, second and third elongated members 21, 23 and 25. If the coil of cable 13 can “free- spin,” a drag system and brake system, to be further explained herein, will not function.
  • the reel 11 also includes a second generally circular flange 61 having a first side 63 and a second side 65.
  • an outer rim of the second flange 61 is circular, and has a same diameter as the first flange 15.
  • the first side 63 of the second flange 61 faces the first side 17 of the first flange 15.
  • the second flange 61 includes first, second and third through holes 67, 69 and 71.
  • the second ends 33, 35 and 37 of the first, second and third elongated members 21, 23 and 25 pass through the first, second and third through holes 67, 69 and 71, respectively, so as to reside beyond the second side 65 of the second flange 61 (best seen in Figure 3).
  • First, second and third partial or full funnel-shaped attachments 73, 75 and 77 are mounted to or integrally formed with the first side 63 of the second flange 61. As depicted in Figure 2, partial funnel shapes are employed, and the first, second and third attachments 73, 75 and 77 are integrally molded with the second flange 61. Each of the first, second and third attachments 73, 75 and 77 is located adjacent to the first, second and third through holes 67, 69 and 71, respectively, to guide the second ends 33, 35 and 37 of the first, second and third elongated members 21, 23 and 25 toward and into the first, second and third through holes 67, 69 and 71, respectively.
  • the reel 11 includes a guidepost 79.
  • the guidepost 79 also functions as a point of support to attach the reel 11 to a reel support structure.
  • the guidepost 79 is formed as a generally cylindrical shaft with a first end 81 attached to a central portion of the first flange 15.
  • One potential manner to attach the first end 81 to the first flange 15 would be to provide a base flange 83 integrally formed with the guidepost 79 with threaded boreholes 85 formed or inserted therein.
  • Short fasteners 87 may be passed through the first flange 15 and engaged into the threaded boreholes 85.
  • other structures may be used to attach the first end 81 of the guidepost 79 to the first flange 15.
  • a second end 89 of the guidepost 79 passes through a guidepost opening 91 formed in a central portion of the second flange 61.
  • Figures 3-7 show the second end 89 of the guidepost 79 residing approximately flush with, e.g., in a same plane as, the second side 65 of the second flange 61.
  • Figures 9-11 show the second end 89 of the guidepost 79 extending beyond the second side 65 of the second flange 61.
  • a lock set includes a first part 93 formed along an exterior portion of the guidepost 79 and a second part 95 attached to the second side 65 of the second flange 61 proximate the guidepost opening 91.
  • the lock set allows the second flange 61 to be selective locked to different positions along the guidepost 79, so that a user can set a desired distance between the first and second flanges 15 and 61.
  • the first part 93 of the lock set may be formed as a guide track 97 with a plurality of locking holes 99.
  • Each locking hole 99 is spaced apart from the other locking holes 99 in a direction from the second end 89 of the guidepost 79 to the first end 81 of the guidepost 79, which is the same direction as a central axis A of the guidepost 79.
  • ten locking holes 99-1, 99-2, 99-3, ...99-10 are illustrated, meaning that the second flange 61 may be locked into ten different positions relative to the first flange 15.
  • the second part 95 of the lock set is formed as a collar 101 attached to the second flange 61.
  • the collar 101 may be attached to the second side 65 of the second flange 61 by a plurality of screws 100 engaged into threaded bore holes 102 fixed to the second flange 61.
  • the collar 101 has an inner opening 103 which is larger than a diameter of the guidepost 79. Therefore, the collar 101 may slide over a section of guidepost 79.
  • the collar 101 includes a spring-loaded plunger 105 captured therein.
  • the spring-loaded plunger 105 has a pin 107 biased to extend away from the collar 101 toward the guidepost 79, so as to engage within a user selected locking hole 99.
  • the spring-loaded plunger 105 includes a handle 109 attached to the pin 107 to manually pull the pin 107 away from the guidepost 79 and disengage the pin 107 from the locking hole 99.
  • the collar 101 may be slid along the guidepost 79, as desired. Releasing the handle 109 allows the spring- loaded plunger 105 to bias the pin 107 toward the locking holes 99, so that the pin 107 may snap into and be locked within another locking hole 99 to secure the collar 101 to the guidepost 79.
  • the second flange 61 is pressed toward the first flange until the coil of cable 13 has its lateral sides engaged by both of the first and second flanges 15 and 61, as show in Figures 6 and 7, and the pin is seated into a hole 99 at that position.
  • the second flange 61 is oriented over the first flange with the first, second and third through holes 67, 69 and 71 generally aligned to the second ends 33, 35 and 37 of the first, second and third elongated members 21, 23 and 25.
  • the handle 109 of the spring-loaded plunger 105 is pulled outwardly (and optionally locked outwardly by features of the spring-loaded plunger 105).
  • the second flange 61 is pressed toward the first flange 15 until it abuts the side of the coil of cable 13 A.
  • the handle 109 is released or unlocked and the second flange 61 is pushed toward the first flange 15 or backed slightly away from the first flange 15 until the pin 107 snaps into one of the holes 99.
  • FIG. 9 The resulting reel 11 is depicted in Figure 9. Note how the second ends 33, 35 and 37 now project well beyond the second side 65 of the second flange 61.
  • Figure 10 shows the reel 11 of Figure 9 with the coil of cable 13A removed. Note how the funnel-shaped attachments 73, 75 and 77 have engaged the first, second and third elongated members 21, 23 and 25. This engagement may cause the first, second and third elongated members 21, 23 and 25 to tilt outwardly, via the elastic washers 38, 40 and 42, which will enlarge the hub to better engage the inner diameter of the coil of cable 13.

Des première, deuxième et troisième tiges cylindriques (21, 23, 25) définissent un moyeu et présentent des premières extrémités (27, 29, 31) fixées au premier flasque (15) et des deuxième extrémités (33, 35, 37) opposées s'étendant à travers des trous (67, 69, 71) formés dans le deuxième flasque (61). Un montant-guide (79) présente une première extrémité (81) fixée au premier flasque (15) et une deuxième extrémité (89) passant à travers une ouverture (91) dans le deuxième flasque (61). Un ensemble de verrous permet de sélectionner une distance entre les premier et deuxième flasques (15, 61). Des positions de fixation des premières extrémités (27, 29, 31) des tiges cylindriques (21, 23, 25) au premier flasque (15) sont réglables manuellement ou automatiquement pour modifier un diamètre du moyeu. Des douilles (115, 117) à l'intérieur d'ouvertures (111, 113) d'extrémités du montant-guide (79) régulent la vitesse de dévidage par rotation du touret (11), et une entité de stationnement au parc est placée à la deuxième extrémité (89) du montant-guide (79) pour bloquer la rotation du touret (11).
