1. Technical Field
This invention relates generally to cable, and in particular to a packaging and carrying case for packaging, carrying and dispensing cable.
2. State of the Art
In today's digital world, cables are commonly employed to carry signals from location to location and between various electronic devices. For example, coaxial cables, fiber optic cables, and other multi-conductor cables are widely used to carry high-frequency electrical signals from one location to another.
A coaxial cable, in particular, typically comprises an elongate inner conductor, a tubular outer conductor, and a dielectric separating the inner and outer conductors. An outer insulating jacket may also be applied to surround the outer conductor. Given the size of these cables and the materials from which they are usually constructed, these cables normally cannot be tightly coiled without kinking. Thus, to protect these cables, they are packaged in pre-fabricated cardboard boxes or wrapped around rigid spools or reels.
Cable installers are frequently called upon to install cable at different locations for various reasons. For example, a cable installer may be asked to connect a new internet or cable-TV customer to a trunk cable or pedestal from which a signal flows. To accomplish this, the installer typically carries one or more of relatively large boxes containing cable, reels of cable, or reels of cable within in a case to the installation site to connect the customer to the trunk cable. The installer manually dispenses the cable from the larger supply, measures and cuts the desired length of cable, installs respective connectors onto the ends of the cable, and uses this prepared cable to connect the customer's interface to the pedestal or trunk cable.
However, the process of carrying and dispensing the desired length of cable from the larger supply, either from the large box or the case, at the installation site can be a burdensome and/or wasteful endeavor. For example, when dispensed from many of the large boxes, as well as the cases, the cables tend to kink and become damaged. Further, these large boxes are not reusable and installers generally have a difficult time transporting these large boxes from place to place at the installation site. In addition, these boxes and cases are also not sufficiently strong to prevent the cable therein from being damaged in the ordinary course of business, such as when the box falls, is crushed by other boxes, or gets tossed around and banged up. Once kinked or damaged, the cable is defective and can no longer be used, resulting in excessive waste. Moreover, many of the boxes and cases, including their inner contents, are not made from recyclable material and thus cannot be recycled.
Thus, there is a need within the cable industry for a cable carrying case that addresses the concerns outlined above. Specifically, there is a need for a cable carrying case that is re-usable, recyclable, protects the cable from damage, and is easy to use by the installers.
The present invention relates to cable, and in particular to a packaging and carrying case for packaging, carrying and dispensing cable.
One aspect disclosed herein is a case that holds cable spools, the case having two halves, a first half and a second half that are coupled together at a first fastener on a first side of the case and a second fastener on a second side of the case, the first and second halves being movable between an open position and a closed position by releasing or securing the fasteners, respectively.
Another aspect disclosed herein includes the case further comprising a cylindrical protrusion. In the open position, the center hole of a spool/reel of cable can be slid onto the cylindrical protrusion that is releasably attached to the inner surface of either the first or second half at a receiving port on the inside surface of the first half and the second half. When the cylindrical protrusion is attached to the first half at the receiving port, the exposed end of the cylindrical protrusion is attached to the receiving port of the second half upon the case being closed, and vice versa. The cylindrical protrusion further comprises exposed ends, the exposed ends of the cylindrical protrusion having a smaller diameter than the remaining diameter of the main body of the cylindrical protrusion. Also, in the closed position, the cylindrical protrusion can support the weight of the spool of cable that has been placed thereon. This is due to the smaller diameter of the exposed ends being secured to, and supported within, the circular receiving ports, which thus fixes (or stabilizes) the cylindrical protrusion within the case. In this configuration, the spool may also rotate about the cylindrical protrusion in response to the cable being pulled from the case.
Another aspect disclosed herein includes the case being repeatedly used. Because the case can move between the opened and closed position, it is reusable, in that once a spool of cable is used up, the case can be opened and a new spool of cable can be inserted in its place. The case is thereafter closed and can be carried or moved to where it is needed next.
Another aspect disclosed herein includes the ease of use of the case. For example, to remove the cable from the case, the case has an opening on each side of the case under the first and second fasteners respectively. The opening is such that the end of the cable can be inserted through the opening and conveniently pulled off the spool, as needed. This particular configuration allows the cable to not tangle on itself or kink as it is being released from the spool. Also, although not necessarily pictured, the case may also have a securing mechanism that secures the free end of the cable to the case during storage of the case or when the cable is not being pulled off the spool.
Another aspect disclosed herein includes the case being made of a rigid, recyclable material. In this rigid, durable configuration the case suitably protects its inner contents (i.e., the frame of the spool and the cable itself).
Another aspect disclosed herein includes the case further comprising connection ports positioned on the top of the case for connecting and supporting a shoulder strap.
The foregoing and other features and advantages disclosed herein will be apparent from the following more detailed description of the particular embodiments of the invention, as illustrated in the accompanying drawings.
As discussed above, embodiments of the present invention relate to cable carrying cases, and in particular to a reusable carrying case for carrying and dispensing cable from a spool or reel.
As shown in
Each of the first and second halves 12 and 14, respectively, is configured in a square-shaped dome that has a surface 20, best seen in
With reference particularly to the first half 12, shown in
The first opening 30 is a horizontal, u-shaped opening defined by the secondary surface 22. In the embodiment shown in
The particular positioning of the first opening 30 is important because it facilitates the payout of the cable 52 from the cable spool 50 and prevents the cable 52 from being damaged. The first opening 30 is positioned on the lower portion of the secondary surface 22 and corresponds with the payout position of the cable 52 on the spool 50 that is housed within the case 10. In this configuration, the cable 52 can be paid out from the case 10 at the proper angle to avoid kinking the cable 52. Also, the shape and size of the first opening 30 functions to hold the cable 52 in place when not in use, as shown in
Similarly to the first opening 30, the second opening 40 is a horizontal, u-shaped opening located on the secondary surface 24 of the first half 12 and near the secondary surface 28. In the embodiment shown in
The particular positioning of the second opening 40 is important because, like the first opening 30, it facilitates the payout of the cable 52 from the cable spool 50 and prevents the cable 52 from binding, or from being damaged and kinked as it is paid out off the spool 50. To avoid the cable 52 from binding during payout and to avoid kinking the cable 52, the second opening 40 is positioned on the lower portion of the secondary surface 24 to correspond to the lower end of the spool 50. Also, the positioning of the second opening 40 in the secondary surface 24 corresponds to the positioning of the first opening 30 in the secondary surface 22. Having the opening 30 in the front of the case 10 and the opening 40 in the rear of the case 10 allows the spool of cable 50 to be placed within the case 10 in either a left-side payout configuration or a right-side payout configuration. As a result, installers that are either left-hand dominant or right-hand dominant can dispense the cable 52 in the appropriate and most convenient, easy-to-use manner.
The receiving port 32 is positioned on an interior face 70 of the surface 20. The receiving port 32 is positioned in a centralized portion of the interior face 70 and extends substantially orthogonally from the interior face 70. As shown, the receiving port 32 is a circular-shaped port, but may assume any shape that allows the receiving port 32 to receive the axial opening 54 of the spool 50. The receiving port 32 is also positioned on the second half 14 in much the same way as the receiving port 32 is positioned on the first half 12, as shown in
In addition to the function described above with respect to the receiving ports 32, the receiving ports 32 are also structurally configured to receive the support member 60. The support member 60, as shown, is a cylindrical-shaped protrusion or rod. However, the support member 60 may assume any other shape that allows the support member 60 to adequately support the weight of the spool of cable 50 placed thereon and allow the spool of cable 50 to rotate thereabout as cable 52 is paid out. The axial opening 54 of the spool of cable 50 is slid onto and over the support member 60.
Of course, if the support member 60 is used in conjunction with the receiving ports 32, the shape of the receiving ports 32 and the shape of the support member 60 must coincide to allow the support member 60 to be placed within the receiving port 32 and be supported thereby. To do so, the support member 60 has outer ends 62 on each of its ends. The outer ends 62 have an axial width substantially equal to the depth of the receiving port 32, and the outer ends 62 also have a diameter less than the diameter of the support member 60. The outer diameter of the receiving port 32 is substantially the same as the outer diameter of the support member 60 and the inner diameter of the receiving port 32 is substantially the same as the diameter of the outer ends 62. Thus, the outer ends 62 of the support member 60 are able to slide into and be supported by the receiving port 32.
The dimensions of the first half 12 and the second half 14 correspond to the diameter of a standard reel of cable 50. This allows the case 10 to properly house the reel or spool 50 to protect the spool 50 from damage and to facilitate proper payout of the cable 52 from the spool 50. Specifically with reference to proper payout of the cable 52, to avoid the problem of backlash when the cable 52 is paid out from the case 10, the first half 12 and the second half 14 are configured to have suitable dimensions to allow the interior faces of the respective secondary surfaces 22, 24, 26, 28 to function as barriers to prohibit the cable 52 from unintentionally unraveling or unwinding from off the spool 50. In this way, the interior faces of the respective secondary surfaces 22, 24, 26, 28 restrict the cable 52 from jumping over the outer flanges 56 of the spool 50, which can lead to the cable 52 becoming kinked and/or jammed, either of which would prohibit the efficient payout of the cable 52 from the case 10. However, the configuration of the case 10 addresses these issues and reduces the possibility of the cable 52 jumping over the outer flanges 56.
The anti-friction member 34 and the reinforcing members 42 are each positioned on the interior face 70. The anti-friction member 34 is shown in
The reinforcing members 42 function to further strengthen the rigidity of the halves 12 and 14 to protect the spool 50 and cable 52 from damage which might otherwise result from impact, collision and exterior pressure on the case 10.
The feet 36 are positioned in the secondary surface 28 at a predetermined interval. The feet 36 allow the first half 12, and the case 10 when the first half 12 is fastened to the second half 14, to rest up off a horizontal surface but squarely on that surface. The feet 36 provide stability to the case 10 when the case 10 is placed upon the ground or other surface. As shown in
As shown in
The front fastener 16 functions in a like manner. Specifically, when the first half 12 and the second half 14 are coupled together at the front fastener 16, the secondary surface 22 of the first half 12 and the secondary surface 24 of the second half 14 function as respective leafs of a butt hinge and the knuckles on the secondary surface 22 of the first half 12 and the knuckles on the secondary surface 24 of the second half 14 interact to form the knuckles of the butt hinge. A pin with a tip can then be inserted down through the respective knuckles to complete the hinge mechanism. Once complete, the front fastener 16 functions similarly to a butt hinge and the first half 12 and second half 14 can pivot between the open position and the closed position about the front fastener 16.
Because the case 10 can move between the opened and closed positions, it is reusable, in that once the spool of cable 50 is used up, the case 10 can be opened and a new spool of cable 52 can be inserted in its place. The case 10 is thereafter closed and can be carried or moved to the location where it is needed next.
The first half 12 further comprises a shoulder strap fastener 44 positioned on the secondary surface 26 near the secondary surface 24. A shoulder strap, not shown, may be attached to the first half 12 by way of the shoulder strap fastener 44. Moreover, the second half 14 comprises a similar fastener. Accordingly, the shoulder strap, not shown, may be attached to the second half 12 by way of its corresponding shoulder strap fastener. In such a configuration, the shoulder strap facilitates the transportation of the case 10 by the installer.
In the embodiment shown in
Structuring the case 10 to be comprised of two identical, yet opposing halves, 12 and 14, provides several advantages over other cases. For example, if only one half, 12 or 14, of the case 10 is damaged, only that damaged half need be replaced by an identical replacement half. Thus, the entire case 10 does not need to be disposed of if only one half, 12 or 14, is damaged. This significantly reduces the replacement cost of the case 10. Further, manufacturing costs are reduced by half, because only one mold is needed to produce both halves 12 and 14 of the case 10.
In an alternative embodiment, the first half 12 and the second half 14 may further comprise a handle 80, as shown in
In another alternative embodiment, as shown in
In another alternative embodiment, the first half 12 and the second half 14 of the case 10 may be structured to be different from one another. For example, as shown in
As shown in
In some embodiments, the cable securing section 31 is an angled section having a v-like shape. The v-like shape can formed by placing a tapered end portion in the first opening 30 that functionally meets the second opening 40 under the condition that the case 10 is in the closed position. The resulting v-like shape allows the initial point of the cable securing section 31 to be wider than the width of the cable 52 and also to be small enough at its end point so that the cable securing section 31 can effectively grip and secure the cable 52 to the case 10. Moreover, to assist in the gripping of the cable 52, the cable securing section 31 can have an edge surface with raised portions thereon to effectively grip and retain the cable 52. The edge surface may be a ribbed edge, a toothed edge, or other like edge that functions to better grip the outer surfaces of the cable 52. Further, the edge surface may be covered or layered with a material to further assist the gripping and retention of the cable 52. For example, the edge surface may have attached thereto any material that better secures the cable 52 to the case 10. Thus, under the condition that the first half 12 and the second half 14 are placed together to form the case 10, the cable 52 can be secured to the case 10 by pulling the cable 52 into the cable securing section 31. The pressure from the straight edge of the second half 14 acts to push the cable 52 into the cable securing section 31 resulting in the cable 52 being secured to the case 10. To thereafter release the cable 52, the user simply lifts up on the cable 52 to release the gripping effect of the cable securing section 31 on the cable 52.
In addition to the cable securing section 31, the first half 12 also comprises a spool securing member, not pictured, that functions to restrict the spool 50 from rotating around the support member 60 when the spool 50 is not in use.
Further to
As mentioned above with respect to
As shown in
The halves 12 and 14 further comprise an aperture 88 in the surface 20 of the halves. The aperture 88 is configured to allow the user to access the spool of cable 50 within the case 10. Specifically, under the condition that the cable 52 has been paid out from the case 10 and a remaining unused portion of the cable 52 extends from the case 10, it is necessary to reel the cable 52 back into the case 10. Using the aperture 88, the user is able to reach into the case and operate the spool 52 to rotate the spool 50 within the case 10 to reel-in the unused portions of the cable 52. In other words, without needing to open the case 10, the user can rewind any unused cable 52 back onto the spool 50 by reaching through the aperture 88 to rotate the spool 50 in the appropriate direction to reel in the cable 52.
As mentioned briefly above, case 10 may further comprise the auxiliary member 90, shown in
Auxiliary member 90 further comprises the mating openings 96 that function to allow the auxiliary member 90 to fasten or couple to the case 10, as shown in
As shown in
In one embodiment, the case 10 is comprised of recyclable material, such as rigid recyclable plastic. Likewise, the cable spool 50 can be made of one or more recyclable materials, including cardboard, plastic, metal, paper, wood, as mentioned above. Also, the spool 50 generally has cable 52 placed thereon prior to placing the spool 50 in the case 10. Nevertheless, the cable 52 may also be wound on the spool 50 after the spool 50 has been placed within the case 10. Once the cable 52 is exhausted off the spool 50, the spool 50 can be removed from the case 10 and recycled. A new spool 50 is then placed within the case 10 and the user can get back to work.
In addition to that materials listed above, the case 10 may be comprised of any material suitable for protecting the inner contents of the case, specifically the reel of cable 50 and the cable 52 thereon. For example, the components defining the above-described case 10 may be formed of any of many different types of materials or combinations thereof that can readily be formed into shaped objects provided that the components selected are consistent with the intended operation of the case 10. The components may be formed of: rubbers (synthetic and/or natural) and/or other like materials; glasses (such as fiberglass) carbon-fiber, aramid-fiber, any combination thereof, and/or other like materials; polymers such as thermoplastics (such as ABS, Fluoropolymers, Polyacetal, Polyamide; Polycarbonate, Polyethylene, Polysulfone, and/or the like), thermosets (such as Epoxy, Phenolic Resin, Polyimide, Polyurethane, Silicone, and/or the like), any combination thereof, and/or other like materials; composites and/or other like materials; metals, such as zinc, magnesium, titanium, copper, iron, steel, carbon steel, alloy steel, tool steel, stainless steel, aluminum, any combination thereof, and/or other like materials; alloys, such as aluminum alloy, titanium alloy, magnesium alloy, copper alloy, any combination thereof, and/or other like materials; any other suitable material; and/or any combination thereof.
Also, a method of using the cable carrying case is provided, as shown in
Once inserted into the case 10, the spool 50 can rotate about the receiving ports 32. Because the spool 50 is rotatable, the cable 52 wound thereon can be paid out off the spool 50 by pulling on the loose end of the cable 52, as shown in step 130. To do so, the loose end of the cable 52 is inserted through the first opening 30 in the front of the case or in the rear of the case, as desired by the user, to expose the loose end of the cable 52 to the outside of the case 10. The loose end of the cable 52 can be inserted through the first opening 30 either before the spool 50 is placed within the case 10 or after the spool 50 is placed within the case 10. The user can then payout the cable 52 from the spool 50 and the case 10 by pulling the desired length of the cable 52 from the case 10.
After the necessary length of cable has been dispensed from the case 10, the loose end of cable 52 can be secured to the case 10 to prevent the loose end of cable 52 from further paying out from the case 10, as shown in step 140. The user can insert the cable 52 into the cable securing section 31 that is structured to retain the loose end of cable 52 and prevent the cable 52 from unwantingly unwinding off the spool 50. Also, the user can insert a finger into the aperture 88 to rewind the extra length of cable 52 that has been unwound from the spool 50. The aperture allows the user to rotate the spool 50 in the direction to rewind the cable 52 back onto the spool 50. Thus, when the cable 52 has been rewound to the appropriate length, the loose end of the cable 52 can be placed in the cable securing section 31. Then, when the cable 52 is again needed, the user can remove the loose end of the cable 52 from the cable securing section 31 and payout the necessary length of cable 52 from the case 10.
After the cable 52 is exhausted from off the spool 50, the user can replace the spool 50 by moving the case 10 from its closed position to its open position by the method described above, as shown in step 150. Doing so decouples the receiving port 32 from one of the center portions 54. The spool 50 can be lifted off the remaining receiving port 32 to decouple the spool 50 from the remaining receiving port 32, as shown in step 160. Once decoupled from each receiving port 32, the exhausted spool 50 can be recycled, as shown in step 170.
Then, to replace the spool 50 within the case, the steps described above can be repeated. Thus, the cable case carrying system described above and method of use thereof allow a user to repeatedly carry, protect, and efficiently payout the cable 52 off a recyclable spool 50, often times made of cardboard, within a recyclable, rigid case 10.
