DESCRIPTION

The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar elements. While embodiments of the invention may be described, modifications, adaptations, and other implementations are possible. For example, substitutions, additions, or modifications may be made to the elements illustrated in the drawings, and the methods described herein may be modified by substituting, reordering, or adding stages to the disclosed methods. Accordingly, the following detailed description does not limit the invention.

Consistent with embodiments of the invention, a cart may be provided. The cart may comprise a support member, one or more wheels, and a receiving member. The wheel or wheels may be connected to the support member. The receiving member may be attached to the support member. The receiving member may be freely slideable along the support member.

Consistent with embodiments of the invention, a container may be provided. The container may comprise a container and a base. The container may define a volume that may house a length of conductors. A conductor may be any material that may conduct electricity, light, or any signal. Examples of a conductor may include copper wire, a fiber optic cable, and aluminum wire. Example lengths of conductors housed in the container may include, 500 feet, 2,500 feet, and 5,000 feet. The base may be connected to the container. The base and container may define an indentation along a perimeter where the container and the base meet.

FIGS. 1-3 show an embodiment of a cart 100. Cart 100 may comprise a first support member 102, a second support member 104, a first wheel 106, a second wheel 108, a third wheel 110, a fourth wheel 112, and a receiving member 114. First wheel 106 and second wheel 108 may be connected directly to first support member 102 or may be connected to cart 100 via a first angled connection member 120. Third wheel 110 and fourth wheel 112 may be connected directly to second support member 104 or may be connected to cart 100 via a second angled connection member 122. While FIGS. 1-3 show four wheels, any number of wheels may be utilized to move the cart.

Receiving member 114 may be connected via one or more of a plurality of sliding members. The plurality of sliding members may comprise, but are not limited to, a first sliding member 124, a second sliding member 126, a third sliding member 128, and a fourth sliding member 130. Receiving member 114 may be connected to first support member 102 via first sliding member 124 and second sliding member 126. Receiving member 114 may be connected to second support member 104 via third sliding member 128 and fourth sliding member 130. While FIGS. 1-3 show four sliding members, any number of sliding members may be utilized to connect receiving member 114 to first support member 102 and second support member 104. The sliding members may include, for example, bearings, grease plugs, and other friction reducing elements to facilitate receiving member 114's movement along first support member 102 and second support member 104.

Ones of the plurality of sliding members may completely encircle first support member 102 and second support member 104 or they may partially encircle first support member 102 and second support member 104. For example, first sliding member 124 and second sliding member 126 may fully encircle first support member 102, and third sliding member 128 and fourth sliding member 130 may partially encircle second support member 104. This configuration may allow receiving member 114 to pivot about first support member 102. In other words, first sliding member 124 and second sliding member 126 may act as hinges that may allow receiving member 114 to rotate about first support member 102. In addition, receiving member 114 may be detachable from first support member 102 and second support member 104 when the sliding members do not fully encircle first support member 102 and second support member 104.

Receiving member 114 may include an upper fork 132 and a lower fork 134. Upper fork 132 and lower fork 134 may be curved (i.e., curved receivers) to match a profile of a container. For example, upper fork 132 may receive an upper portion of the container and lower fork 134 may receive a lower portion of the container. In addition, upper fork 132 and lower fork 134 may comprise tines that may extend and lock into place to better secure the container to cart 100. For instance, upper fork 132 and lower fork 134 may be constructed of a tubular or other hollow stock. The tines may extend and retract into upper fork 132 and lower fork 134. The tines may have a curved profile. As the tines extend from upper fork 132 and lower fork 134, the tines may wrap around the container or other item located proximate receiving member 114. The tines may be held in place by a pin that may pass through the tines and upper fork 132 and lower fork 134. In addition, the tines may have a protrusion that may act as a handle or grip. The protrusion may engage notches or groves located in upper fork 132 and lower fork 134 to secure the tines in place. In addition, a strap 136 may be used to better secure the container to cart 100.

A hook 138 (see FIG. 3) may be used to grip the container. During operation, hook 138 may extend and retract from a tube 140. Hook 138 may catch an indentation or band located on the container. As cart 100 is tilted rearward, hook 138 may catch the container and allow a user to apply greater leverage to the container.

A wire guide 142 (see FIG. 3) may be attached to cart 100. Consistent with embodiments, wire guide 142 may be attached to first support member 102, second support member 104, or receiving member 114. Wire guide 142 may have a fixed position or it may be movable. For example, wire guide 142 may have a fixed position along first support member 102. For instance, wire guide 142 may be welded to first support member 102. Wire guide 142 may be movable along first support member 102. For instance, first support member 102 may have a plurality of holes drilled into it. Wire guide 142 may have a peg that may be inserted into one of the plurality of holes to allow a user to reposition wire guide 142 as desired. In addition, wire guide 142 may comprise a snout 144. Snout 144 may be rotatable, flexible, ridged, and removable.

Wire guide 142 may facilitate removal of the conductors from the container. Wire guide 142 may also include additional features not shown such as a twister and devices that may braid or bind conductors as they are removed from the container. Wire guide 142 may provide the conductors a smooth transition away from the container by providing a common path for the conductors to travel. The common path may help minimize tangling of the conductors. In addition, wire guide 142 may allow the conductors to be pulled from the container without damage to the conductors. Wire guide 142 may comprise a locking mechanism (not shown) that may comprise a choking member located internal or external to wire guide 142. The choking member may hinder the conductors from traveling back into the container. For instance, during operation an electrician may pull conductors (e.g., wires or cables) through wire guide 142. The choking member may then prevent the conductors from slipping back into the container. This may prevent the electrician from having to feed the conductors though wire guide 142 every time he cuts the conductors.

FIG. 4A through FIG. 4M illustrate an embodiment of cart 100's operation. FIG. 4A shows cart 100 approaching a container 402. Container 402 may be located on an elevated surface (e.g., a first pallet 404) and comprise a base 406. Cart 100 may be maneuvered while on two or four wheels. During initial movement of cart 100, receiving member 114 may be in a lower position as shown in FIG. 4A. The lower position may comprise the lowest position that receiving member 114 can be in along first support member 102 and second support member 104.

FIG. 4B shows that as cart 100 approaches container 402, lower fork 134 may contact base 406. Upon initial contact with base 406, receiving member 114 may be in the lower position. Base 406 and container 402 may define an indentation (e.g. indentation 1204 described in more detail below with respect to FIG. 12A and FIG. 12B) along a perimeter where the container and the base meet. Lower fork 134 may slide into the indentation. As lower fork 134 makes contact with base 406 and the bottom of container 402, receiving member 114 may begin to traverse (e.g. slide) up first support member 102 and second support member 104.

FIG. 4C shows as cart 100 further approaches container 402, receiving member 114 may be partially coupled to container 402. As receiving member 114 gets closer to base 406, base 406 may apply a force to lower fork 134 that may cause receiving member 114 to traverse up first support member 102 and second support member 104 as indicated by arrow 408. As shown in FIG. 4B through FIG. 4C, cart 100's angle relative to container 402 may begin to decrease. In other words, as receiving member 114 increases its contact with container 402 and traverses the support members, cart 100 may approach a more vertical position. The movement of receiving member 114 may be accomplished only due to the force exerted on lower fork 134 by base 406. The freely sliding nature of receiving member 114 may mean that receiving member 114's movement may not be accomplished or assisted by elements such as, for example, springs, shocks, motors, or actuators. Receiving member 114's ability to traverse first support member 102 and second support member 104 may allow cart 100 to receive container 402's elevated surfaces without having to lift cart 100 off the ground.

FIG. 4D shows upper fork 132 receiving container 402. In other words, cart 100 has reached a near vertical position and receiving member 114 contacts container 402. As a result, receiving member 114 has traversed from the lower position to an upper position without the assistance of elements such as springs, shocks, motors, or actuators. Note that this traversal may be accomplished by an operator rolling cart 100 on its wheels into the position shown in FIG. 4D. The height of the upper position may be a function of the height of first pallet 404. In other words, if first pallet 404 were taller or shorter than shown in FIG. 4D, the upper position would be correspondingly different.

FIG. 4E shows that after upper fork 132 has received container 402, strap 136 may be utilized to secure container 402 to receiving member 114. In addition, tines may be extended from upper fork 132 and lower fork 134. The tines may have a curved profile. As the tines extend from upper fork 132 and lower fork 134, the tines may wrap around container 402. The ends points of the tines may connect to one another to secure container 402 to cart 100. Furthermore, strap 136 may be connected to the tines and secure container 402 to receiving member 114. Hook 138 may be secured to a top portion of container 402 and may allow for greater leverage to be applied to container 402 when cart 100 is tilted back.

Once strap 136 has secured container 402 to receiving member 114, container 402 may be lifted from first pallet 404. To lift container 402 from first pallet 404, cart 100 may be tilted back such that first wheel 106, second wheel 108, third wheel 110, and fourth wheel 112 contact the ground as shown in FIG. 4F. As cart 100 is being tilted back, receiving member 114 may traverse first support member 102 and second support member 104 as indicated by arrow 412 from the upper position back down to the lower position. Due to the free floating nature of receiving member 114, its movement indicated by arrow 412 may occur without the assistance of elements such as, for example, springs, shocks, motors, or actuators.

After container 402 is lifted from first pallet 404, FIG. 4G shows that container 402 may be transported using cart 100 to a new location. The operator may roll cart 100 on the wheels with container 402 attached to the new location. Note that receiving member 114 is in the lower position.

As shown in FIG. 4H, after transporting container 402 to the new location, cart 100 may approach a second elevated surface (e.g., a second pallet 414). Note that receiving member 114 is in the lower position as cart 100 approaches the second elevated surface.

Once cart 100 approaches second pallet 414, FIG. 4I shows that cart 100 may be tilted forward to begin placing container 402 onto second pallet 414. During tilting of cart 100, receiving member 114 may traverse first support member 102 and second support member 104 as indicated by arrow 416 from the lower position. Receiving member 114's ability to traverse first support member 102 and second support member 104 may allow cart 100 to place container 402 elevated surfaces without having to lift cart 100 off the ground.

As shown in FIG. 4J, once cart 100 is tilted forward to place container 402 onto second pallet 414, container 402 may be securely placed on second pallet 414 and strap 136 may be removed. Receiving member 114's position may be at the upper position. The height of the upper position may be a function of the height of second pallet 414. In other words, if second pallet 414 were taller or shorter than shown in FIG. 4J, the upper position would be correspondingly different.

After container 402 is placed on second pallet 414 and strap 136 is removed, FIG. 4K shows that cart 100 may begin to be moved away from container 402. Cart 100 may be tilted back or may remain in a vertical position. As cart 100 is being moved away from container 402, receiving member 114 may begin to traverse first support member 102 and second support member 104 from the upper position downward as indicated by arrow 418.

FIG. 4L shows that as cart 100 is initially moved away from container 402, cart 100 may be completely removed from container 402. As shown in FIGS. 4K and 4L, lower fork 134 may contact base 406 as receiving member 114 traverses first support member 102 and second support member 104 downward to rest in the lower position. FIG. 4M shows cart 100 may be moved away from container 402 after relocating container 402 from first pallet 404 to second pallet 414. As shown in FIG. 4M, receiving member 114 may be in the lower position.

While FIGS. 4A through 4M show cart 100 and receiving member 114 as one unit that receives container 402, embodiments may comprise receiving member 114 being permanently attached to container 402. In these embodiments, cart 100 and container 402 may be one unit. Still consistent with embodiments, receiving member 114 may be detachable from cart 100. For example, first sliding member 124, second sliding member 126, third sliding member 128, and fourth sliding member 130 may be configured to detach from first support member 102 and second support member 104. Receiving member 114 may be permanently attached to container 402 and cart 100 may be attached to receiving member 114. Receiving member 114 may be removable from both container 402 and cart 100 as well.

FIG. 5 shows a system 500 that may be used to estimate an amount of conductor located in container 402. System 500 may comprise container 402, base 406, an electronic display 502, and transducers 504. Transducers 504 may be, for example, piezoelectric sensors that may create a signal (e.g., a voltage) when a stress (i.e., the weight of wire in container 402) is applied to transducers 504. The signal may be transmitted to a computing device associated with electronic display 502.

Electronic display 502 may be connected to cart 100 or may be a standalone unit that may be connected to and removed from container 402 as needed. Transducers 504 may also be located on upper fork 132 and lower fork 134. When located on upper fork 132 or lower fork 134, transducers 504 may create a voltage in response to a stress applied to upper fork 132 and lower fork 134.

In addition, container 402 may comprise a hole 506. One end of the wire 508 located in container 402 may pass through hole 506. An electrician may use a multimeter to measure the total resistance between the one end of the wire 508 and another end of the wire 510. The total resistance may be inputted into electronic display 502 to calculate an amount of wire remaining in container 402.

Electronic display 502 may include an application running on a computer 600 (e.g. the computing device), shown in FIG. 6, that may receive information from the transducers that allows computer 600 to calculate an amount of wire remaining in container 402. As shown in FIG. 6, computer 600 may include a processing unit 602, a memory unit 604, a display 606, and an input unit 608. Memory unit 604 may include a software module 610 and a database 612. While executing on processing unit 602, software module 610 may perform processes for determining an amount of conductor remaining in container 402, including, for example, one or more stages included in method 700 described below with respect to FIG. 7.

Computer 600 (“the processor”) may be implemented using a personal computer, a network computer, a mainframe, a smartphone, or other similar computer-based system. Computer 600 may also be configured to transmit data to a supplier or manufacturer. For instance, if there is a problem with the wire in container 402 a user, using computer 600, may a scan barcode located on a label attached to container 402 and transit the information to the supplier of manufacturer of container 402.

The processor may comprise any computer operating environment, such as hand-held devices, multiprocessor systems, microprocessor-based or programmable sender electronic devices, minicomputers, mainframe computers, and the like. The processor may also be practiced in distributed computing environments where tasks are performed by remote processing devices. Furthermore, the processor may comprise a mobile terminal, such as a smart phone, a cellular telephone, a cellular telephone utilizing wireless application protocol (WAP), personal digital assistant (PDA), intelligent pager, portable computer, a hand held computer, or a wireless fidelity (Wi-Fi) access point. The aforementioned systems and devices are examples and the processor may comprise other systems or devices.

FIG. 7 is a flow chart setting forth the general stages involved in method 700 for determining an amount of conductor remaining in container 402. Method 700 may be implemented using, for example, computer 600 as described in more detail above. Ways to implement the stages of method 700 will be described in greater detail below.

Method 700 may begin at starting block 705 and proceed to stage 710 where computer 600 may receive input including information. For example, after using some of the conductor in container 402, an electrician may input the information about container 402 and/or the conductor in container 402 into computer 600 via electronic display 502. For instance, the electrician may input the information such as wire size, container size, sheathing/insulation material, type of metal wire is made of, sheathing/insulation thickness, etc. Moreover, the weight of container 402 may be obtained from the signal supplied by transducers 504. The total resistance of the wire may be inputted as well.

Some or all of the information may be received by computer 600 by reading a barcode on a label attached to container 402. Consistent with embodiments of the invention, the label may be attached to container 402. The label may include the bar code. The barcode may include information about container 402 and the contents of container 402. The electrician may cause computer 600 to read the barcode to gather the information needed to calculate the amount of conductor remaining in container 402. For example, the electrician may cause computer 600 to read the barcode. Computer 600 may use data read from the barcode to lookup needed information from database 612 to calculate the remaining amount of conductor in container 402. Furthermore, computer 600 may use data read from the barcode to query a database over the internet for the needed information. Computer 600 may retrieve information such as, weight per unit length of the conductor in container 402, wire gauge of the conductor, alloy used to construct the conductor and associated properties (e.g., density) of the alloy, and number of wire strands of the conductor. In short, information needed to calculate the remaining conductor in container 402 may be received by computer 600 from transducers 504, via the electrician's inputs into electronic display 502 and/or using the barcode.

From stage 710, where computer 600 received the input, method 700 may advance to stage 715 where computer 600 may calculate the amount (e.g. length) of conductor remaining in container 402. For example, computer 600 may use a formula stored in memory unit 604 to calculate the remaining amount of conductor. The formula may comprise a first component corresponding to the unit length per weight (e.g. ft. per lbs.) for the conductor and a second component corresponding to the weight (e.g. lbs.) of the conductor remaining in the container. These two components may be multiplied to provide the remaining length of conductor in container 402. The first component may be derived from the bar code and/or from data inputted by the electrician into the electronic display 502. The second component may be derived from transducers 504 that may supply the weight of the conductor in container 402 and the weight of container 402 itself. To obtain the second component, the weight of container 402 itself may be subtracted from the weight of the conductor and container 402 supplied by transducers 504.

In stage 715, computer 600 may use the total resistance and the information about the conductor to determine an amount of conductor remaining in container 402. For example, the total resistance may be used in conjunction with the conductor's resistance per foot data to calculate an estimate of an amount of wire located in container 402.

From stage 715, where computer 600 calculates the remaining amount of conductor in container 402, method 700 may advance to stage 720 where electronic display 502 may display the remaining amount of conductor in container 402. In addition, computer 600 may transmit the remaining amount of conductor in container 402 to a supplier, manufacturer, or other entity. For example, computer 600 may transmit the remaining amount of conductor to a supplier notifying the supplier that the electrician may need more conductor. In addition, if there is some defect with container 402 or the conductor located therein, the supplier or manufacturer may be notified and the electrician given a credit, discount, or other monetary compensation. From stage 720, where computer 600 may transmit data, method 700 may end at stage 725.

FIG. 8 shows container 402 connected to cart 100. Consistent with embodiments, a ring 802 may encircle container 402. Ring 802 may comprise a plurality of holes 804 and may be positioned proximate to the top of container 402. A post 806 may extend from upper fork 132. Post 806 may fit with plurality of holes 804 and may secure container 402 to cart 100. For example, post 806 protrude upwards from upper fork 132 and through one of the plurality of holes 804 to mechanically link ring 802 and container 402 to upper fork 132 and cart 100.

While FIG. 8 shows ring 802 arranged to engage upper fork 132, ring 802 may be positioned to engage lower fork 134. In addition, multiple rings may be used and both lower fork 134 and upper fork 132 may engage separate rings. For instance, a second ring comprising a second plurality of holes may be positioned proximate the bottom of container 402 and lower fork 134 may have a second post that may fit one of the second plurality of holes. Furthermore, ring 802's vertical position along container 402 may be adjustable or fixed. For example, ring 802 may be welded or glued to container 402 to maintain a fixed position. For ring 802 to be adjustable, a plurality of screws or bolts may be used to fasten ring 802 to container 402. To adjust ring 802's position, the screws or bolts may be removed, ring 802's position changed, and screws or bolts reinserted to secure ring 802 in a new position. Moreover, the screws or bolts may be removed and ring 802 may be removable from container 402.

FIG. 9 shows container 402 connected to a cap 902. Cap 902 may be permanently attached to container 402 or removable from container 402. Attaching and removing cap 902 may be accomplished with or without tools. During operation, lower fork 134 may interact with a lip 904 and may cause receiving member 114 to traverse (e.g. slide), as described above with respect to FIGS. 4A-4M.

FIGS. 10A and 10B show a cart 1000. Cart 1000 may comprise a support member 1002, a plurality of wheels (e.g., a first wheel 1004 and a second wheel 1006), and a free floating receiving member 1008. The plurality of wheels may be connected directly to support member 1002 or may be connected to an angled connecting member 1010.

Free floating receiving member 1008 may be connected to support member 1002 by a first linkage 1012 and a second linkage 1014. While FIGS. 10A and 10B show two linkages, any number of linkages may be utilized to connect free floating receiving member 1008 to support member 1002. The linkages may include, for example, bearings, grease plugs, and other friction reducing elements to facilitate free floating receiving member 1008's movement. In addition, free floating receiving member 1008 may be detachable from support member 1002.

Free floating receiving member 1008 may include an upper fork 1016 and a lower fork 1018. Upper fork 1016 and lower fork 1018 may be contoured to match a profile of a container such as, for example, a container containing multiple unbound conductors. In addition, upper fork 1016 and lower fork 1018 may comprise tines that may extend and lock into place to better secure the container to cart 1000. In addition, a strap (not shown) may be used to better secure the container to cart 1000. A wire guide (shown in FIG. 3) may be attached to cart 1000 and may be attached to support member 1002 and operate as described above with respect to FIGS. 1-3.

First linkage 1012 and second linkage 1014 may allow free floating receiving member 1008 to change position as described above with respect to FIGS. 4A-4M. The movement of free floating receiving member 1008 may allow cart 1000 to be used to transport containers from a first surface 1020 (e.g. a floor) to an elevated surface 1022 (e.g., a pallet).

FIGS. 11A, 11B, and 11C show a forklift 1100. Forklift 1100 may comprise a pair of forks 1102 (i.e., a left fork 1104 and a right fork 1106, as viewed from a driver's seat 1108). As shown in FIGS. 11A and 11C, during operation, pair of forks 1102 may fit between container 402 and base 406. As pair of forks 1102 are raised or lowered, container 402 may be raised or lowered. In addition, pair of forks 1102 may grip container 402 via a groove 1110. Groove 1110 may be molded into container 402 when container 402 is constructed. In addition, external fixtures may be attached to container 402 to provide a surface for pair of forks 1102 to engage.

The shaped surface may allow conductors to be pulled from container 402 without damage to the conductors. In addition, the shaped surfaces may allow the conductors to be pulled in any direction without damage.

Wire guide 2112 may act to hinder the conductors from falling back into container 402 when not being pulled by a user. For instance, the conductors may have a natural twist imparted upon them as they are pulled from container 402. This natural twist may cause portions of the conductors to rest against the inner surface of wire guide 2112. The friction between the conductors and the inner surface may hinder the conductors from falling back into container 402. Wire guide 2112 may also include a lubricant applying member (not shown) that may apply a lubricant to the conductors as they pass through wire guide 2112.
