The present invention relates in general to electrical wire and cable, and more particularly, to the stackable wire dispensing containers.
Wooden reels or plastic and metal spools are common in the wire and cable industry for winding circuit-size wire. Once wound, the reels and spools are distributed to customers for use at jobsites. Wound reels and spool are often heavy, cumbersome and difficult to carry while on the jobsite due to a lack of a handle. External conditions may also impact the reliability of the reel or spool. For example, in wet conditions, wooden reels act as wicks, absorbing water, and becoming heavier. The reels and spools are prone to damage, such as splintering or shattering, if dropped by the customer. Once damaged, the wire or cable being paid off may become tangled or damaged by the damaged reel or spool as the wire is removed or paid off in a last on/first off format. Reels and spools often require jack stands and a shaft to support the reel or spool during pay-off. The customer must transport and use this additional equipment when dispensing wire or cable from the reel or spool. Additional pulling force is also needed to rotate the entire weight of the reel and its contents during payoff. During payoff, the inertia of the reel or spool may cause the reel or spool to continue to rotate after pulling has ceased, causing “overruns” which increase the risk of tangles and snags and additional damage to the wire or cable.
Prior art containers for dispensing wire without reels or spools include Encore Wire Corporations' co-pending U.S. patent application Ser. No. 14/731,021 entitled “SYSTEM AND APPARATUS FOR WIRE AND CABLE PACKAGING AND PAYOFF” which discloses a system and apparatus for improved wire and cable packaging and payoff. The wire or cable is coiled in a figure 8 pattern and includes an embedded payoff port. The system and apparatus allow the wire to be pulled from the inner diameter of the core rather than the outer diameter along substantially the same axis as the direction of the payoff wire and cable. The coil does not need to move to pay-off and therefore pulling force is minimal. The packaging used to contain the coils eliminates the possibility of tangles or overruns. Another prior art container includes shrink-wrapped wire coils which are typically used for retail distribution of residential wire.
Another prior art container for packaging coils of wire or cable without a spool or reel is the barrel pack. The barrel pack, however, has several disadvantages. For example, the barrel pack has large and significant size and weight characteristics. A traditional barrel pack cannot easily be moved by hand because it weighs several hundred pounds and must be moved with a dolly or machinery.
Therefore, there is a need in the art for an apparatus that is compact, easily transportable, stackable, and capable of spooling several wires while conveniently stacked in any number on the ground or any other surface.
The present invention provides for a stackable wire dispensing container. The stackable wire dispensing container contains a coil of wire and allows the wire to be dispensed without requiring the rotation of the entire coil and package. The removal of the need to rotate the entire reel or spool significantly reduces the pulling force needed to dispense the wire. The stackable wire dispensing container includes a handle or handles to provide ease in transporting or carrying the stackable wire dispensing container containing the wire. Finally, the stackable wire dispensing container may be conveniently stacked in any number for convenient payoff of several wires or wire types or sizes simultaneously or during the same wire pull by the user. The stackable wire dispensing container is advantageous over prior art containers due to the containers' high total footage capacity and typically lower cost as a wide variety of materials may be used in the manufacture of the stackable wire dispensing container without detracting from the spirit of the invention, including less expensive materials. Further, the stackable wire dispensing container uses a standard coiling machine and does not require a figure 8 pattern of coiling of wire. Additionally, the stackable wire dispensing container removes the need to unwrap or cut the shrink-wrap to dispense the wire. When cutting a shrink-wrapped coil, it is easy to make a hole that is too large and will compromise the stability of the coil. The precut payoff holes of the stackable wire dispensing container provide more stability and convenience.
The foregoing summary, as well as the following detailed description, will be better understood when read in conjunction with the appended drawings. For the purpose of illustration, there is shown in the drawings certain embodiments of the present disclosure. It should be understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown.
In the drawings:
The figures are not intended to be exhaustive or to limit the invention to the precise form disclosed. It should be understood that the invention can be practiced with modification and alteration, and that the invention be limited only by the claims and the equivalents thereof.
The following discussion is presented to enable a person skilled in the art to make and use the present invention. The general principles described herein may be applied to embodiments and applications other than those specifically detailed below without departing from the spirit and scope of the present invention. Therefore, the present invention is not intended to be limited to the embodiments expressly shown, but is to be accorded the widest possible scope of invention consistent with the principles and features disclosed herein.
Referring to
In one embodiment, the box enclosure 104 includes slot-shaped cutouts 110 in the top portion 102 and the bottom portion 402 and a circular hole 108 cut into the center of the top portion 102 and bottom portion 402. The circular holes 108 of both the top portion 102 and the bottom portion 402 align on a vertical axis of the stackable wire dispensing container 100. In one embodiment, the slot-shaped cutouts 110 and the circular hole 108 are present in each of the two inner closure flaps 510 and two outer closure flaps 512 of the top portion 102 and bottom portion 402 of the box enclosure 104. The slot-shaped cutouts 110 may be used as handles for carrying the stackable wire dispensing container 100. The wire contained in the stackable wire dispensing container 100 is dispensed through the circular hole 108. The circular hole 108 is present on both the top and bottom of the stackable wire dispensing container 100 so that multiple stackable wire dispensing containers 100 may be stacked on top of each other and the wire from each stackable wire dispensing container 100 may be pulled through the circular holes 108 and out the top of the highest stackable wire dispensing container 100. This allows for the wire from a stackable wire dispensing container 100 on a lower level of the stack to be dispensed simultaneously with the wire from higher stackable wire dispensing containers 100 by dispensing or pulling all the wires through a column formed by the holes 108.
A core 504 is included within the stackable wire dispensing container 100. In one embodiment, the core 504 is a substantially hollow cylinder of a height less than the height of the side walls 106. The core 504 forms an inner core portion 520 and an outer core portion 508. The inner core portion 520 includes the circular hole 108 typically near the center of the inner core portion 520. The outer core portion 508 is the area outside of the core 504. The outer core portion 508 may be bound by the sides 106 or, in one embodiment, by an exterior wall 506. The exterior wall 506 is located within the box enclosure 104 and surrounds the core 504 forming the outer core portion 508. The exterior wall 506 has a height equal to or less than the height of the side 106. The exterior wall 506 may have a height equal to the height of the core 504, however, a wide variety of heights may be implemented without detracting from the spirit of the invention. In one embodiment, the exterior wall 506 is substantially circular. In another embodiment, the exterior wall 506 is substantially hexagonal. A wide variety of exterior wall 506 shapes may be implemented without detracting from the spirit of the invention. In the embodiments with the exterior wall 506, support elements 502 may be located in the corners of the box enclosure 104 to provide support for the stackable wire dispensing container 100. In one embodiment, the support elements 502 are substantially triangular. In another embodiment, the support elements 502 are substantially triangular with one face curved to conform to a substantially circular exterior wall 506. A wide variety of support element 502 shapes and sizes may be implemented without detracting from the spirit of the invention. Wire or cable is placed in the outer core portion 508 for transportation and dispensing.
Referring now to
A fully assembled stackable wire dispensing container 100, according to one embodiment of the invention, includes dimensions of 24″×24″×10″, however, a wide variety of shapes, sizes and dimensions of the stackable wire dispensing container may be implemented without detracting from the spirit of the invention.
Referring now to
It is typical to ship multiple, parallel conductors within one traditional barrel pack. Dispensing the wires from these traditional barrel packs requires extensive user interaction. One advantage of the mini-barrel container 800 is the wire may be lifted and moved by hand because the mini-barrel container 800 is a more manageable size and weight. In one embodiment of the invention, the mini-barrel removable lid 806 includes slot-shaped cutouts (not shown) to be used as handles for movement of the mini-barrel containers 800. The mini-barrel containers 800 also provide the electrical installer more flexibility versus a paralleled barrel pack. With a paralleled barrel pack the installer is forced to dispense all the included conductors simultaneously while dispensing the same length for each conductor. With multiple mini-barrel containers 800, the installer has the option of dispensing all conductors simultaneously or dispensing each conductor for a different length.
Although the invention is described herein with reference to specific embodiments, various modifications and changes can be made without departing from the scope of the invention as set forth in the claims below. Accordingly, the specification and figures are to be regarded in an illustrative rather than a restrictive sense, and all such modifications are intended to be included within the scope of the invention. Any benefits, advantages, or solutions to problems that are described herein with regard to specific embodiments are not intended to be construed as a critical, required, or essential feature or element of any or all the claims.
From time-to-time, the invention is described herein in terms of these example embodiments. Description in terms of these embodiments is provided to allow the various features and embodiments of the invention to be portrayed in the context of an exemplary application. After reading this description, it will become apparent to one of ordinary skill in the art how the invention can be implemented in different and alternative environments. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art to which this invention belongs.
The preceding discussion is presented to enable a person skilled in the art to make and use the invention. The general principles described herein may be applied to embodiments and applications other than those detailed below without departing from the spirit and scope of the invention as defined by the appended claims. The invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
In addition, while a particular feature of the invention may have been disclosed with respect to only one of several embodiments, such feature may be combined with one or more other features of the other embodiments as may be desired. It is therefore, contemplated that the claims will cover any such modifications or embodiments that fall within the true scope of the invention.
The various diagrams may depict an example architectural or other configuration for the invention, which is done to aid in understanding the features and functionality that can be included in the invention. The invention is not restricted to the illustrated example architectures or configurations, but the desired features can be implemented using a variety of alternative architectures and configurations. Indeed, it will be apparent to one of skill in the art how alternative functional, logical or physical partitioning and configurations can be implemented to implement the desired features of the invention. Also, a multitude of different constituent module names other than those depicted herein can be applied to the various partitions. Additionally, with regard to flow diagrams, operational descriptions and method claims, the order in which the steps are presented herein shall not mandate that various embodiments be implemented to perform the recited functionality in the same order unless the context dictates otherwise.
Terms and phrases used in this document, and variations thereof, unless otherwise expressly stated, should be construed as open ended as opposed to limiting. As examples of the foregoing: the term “including” should be read as meaning “including, without limitation” or the like; the term “example” is used to provide exemplary instances of the item in discussion, not an exhaustive or limiting list thereof; the terms “a” or “an” should be read as meaning “at least one”, “one or more” or the like; and adjectives such as “conventional”, “traditional”, “normal”, “standard”, “known” and terms of similar meaning should not be construed as limiting the item described to a given time period or to an item available as of a given time, but instead should be read to encompass conventional, traditional, normal, or standard technologies that may be available or known now or at any time in the future. Likewise, where this document refers to technologies that would be apparent or known to one of ordinary skill in the art, such technologies encompass those apparent or known to the skilled artisan now or at any time in the future.
A group of items linked with the conjunction “and” should not be read as requiring that each and every one of those items be present in the grouping, but rather should be read as “and/or” unless expressly stated otherwise. Similarly, a group of items linked with the conjunction “or” should not be read as requiring mutual exclusivity among that group, but rather should also be read as “and/or” unless expressly stated otherwise. Furthermore, although items, elements or components of the invention may be described or claimed in the singular, the plural is contemplated to be within the scope thereof unless limitation to the singular is explicitly stated.
The presence of broadening words and phrases such as “one or more”, “at least”, “but not limited to” or other like phrases in some instances shall not be read to mean that the narrower case is intended or required in instances where such broadening phrases may be absent. The use of the term “module” does not imply that the components or functionality described or claimed as part of the module are all configured in a common package. Indeed, any or all of the various components of a module, whether control logic or other components, can be combined in a single package or separately maintained and can further be distributed across multiple locations.
