DETAILED DESCRIPTION OF THE INVENTION

The present invention now will be described more fully hereinafter with reference to the accompanying figures, in which exemplary embodiments of the invention are shown. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Like reference numerals refer to like elements throughout.
FIGS. 1 a and 1 b shows an exemplary embodiment of the present invention. The present invention is directed to a device 1 that can be used for straightening electrical cords, such as those cords found on common household appliances. However, it is understood that the present invention is suitable for straightening all types of electrical cords and wires. Many electrical cords for appliances include two conductors of similar size surrounded by an insulating material, i.e. rubber, joined together, and divided by additional insulating material at the point where the insulated conductors are joined together. The cross-section configuration of such electrical cords is generally two substantially circular regions on opposing sides of a thin rectangular region. The configuration is similar to that of a shotgun.
The embodiment of the present invention shown in FIGS. 1 a and 1 b, includes a first portion 10 and a second portion 12 positioned substantially opposite to the first portion 10. The first 10 and second 12 portions shown in FIG. 1 have a generally semi-circular shape, but it is understood that various shapes may be suitable for the present invention. The first 10 and second 12 portions each include at least one pair of grooves 15 that are dimensioned for receipt of an electrical cord. The first portion 10 includes a first set of grooves 15′, and the second portion includes a second set of grooves 15. Each set of grooves 15, 15′ may include two grooves. For example, set of grooves 15 includes a first groove 25 and a second groove 35 separated by a raised region 17. Each groove 25, 35 of the set of grooves 15 has a substantially semi-circular cross-section shape. The set of grooves 15′ on the first portion 10, and the set of grooves 15 on the second portion 12 are substantially parallel to each other.
As shown in FIGS. 1 a and 1 b, the electrical cord straightening device 1 may include multiple pairs of grooves, and accordingly same size grooves on the first portion 10 are substantially parallel to the same size grooves on the second portion 12. The first 10 and second 12 portions may be coupled together by a hinge mechanism 14. The hinge mechanism allows the first 10 and second 12 portions to swing away from each other in a clam-shell like fashion. On the opposing side as the hinge mechanism 14, the electrical cord straightening device may include a latching mechanism 16 that is configured to secure the first 10 and second 12 portions together when the electrical cord straightening device is in a closed position. The latching mechanism 16 may be any sort of device that can securely fasten the first 10 and second 12 portions together, such as a latch, strap or clip.
Still referring to FIGS. 1 a and 1 b, in the closed position corresponding sets of grooves 15, 15′ on the first 10 and second 12 portions form a pair of channels that are dimensioned for receipt of a two-conductor electrical cord, such as those used for household appliances. The raised region 17 separating each groove 25, 35 of the second set of grooves 15 do not meet with the raised region 17′ on the opposing first set of grooves 15′ to allow space for the insulating material found between the two conductors of the electrical cord. Therefore, when the electrical cord straightening device 1 is in the closed position, as shown in FIG. 1 for example, the electrical cord fits snuggly into the channels defined by the sets of grooves 15, 15′.
In operation, the electrical cord straightening device 1 is swung open, i.e. the first 10 and second 12 portions are swung away from each other by way of the hinge mechanism 14, and an electrical cord is placed in a set of grooves corresponding to the gauge of the electrical cord. The electrical cord straightening device 1 is then closed by brining the first 10 and second 12 portions together, and may be secured together by the latching mechanism 16. The electrical cord straightening device 1 is then drawn down the length of the electrical cord, which acts to remove kinks and bends from the electrical cord, thereby straightening the electrical cord.
FIG. 2 shows another exemplary embodiment of the present invention. The embodiment shown in FIG. 2 includes first 10 and second 12 portions as discussed with reference to FIGS. 1 a and 1 b, however the first 10 and second 12 portions are substantially rectangular in their cross-sections. However, it is understood that the cross-sectional shape of the first 10 and second 12 portions is merely exemplary, and that the present invention may include first 10 and second 12 portions of any cross-sectional shape. The embodiment shown in FIG. 2 includes a single pair of grooves 15 on second portion 12, and a single part of grooves 15′ on the first portion 10. While the electrical cord straightening device 1 shown in FIG. 2 is shown with a hinge mechanism 14 and latching mechanism 16, it is understood that the electrical cord straightening device 1 may be permanently affixed to the electrical cord for a household appliance. In that embodiment, the first 10 and second 12 portions may be joined together during the manufacturing of the appliance so that the electrical cord straightening device 1 may freely slide down the electrical cord, but cannot be removed. The electrical cord straightening device 1 shown in FIG. 2 may include at least one finger groove 20 on the surface of either the first 10 or second 12 portions opposite the pairs of grooves 15, 15′. It is understood that while the finger grooves 20 are shown in the first portion 10, they may also be located on the second portion 12, or both. The finger grooves 20 may be dimensioned to allow a user to place at least one finger into each finger groove 20 while using the electrical cord straightening device.
FIG. 2 also shows that it is possible to achieve a gap between the raised region 17 on the second portion 12, and the raised region 17′ on the first portion 10 by positioning the hinge mechanism 14 and the latch mechanism 16 so that there is a gap between the first portion 10 and the second portion 12. In this manner it is possible to accommodate the insulating material that is found between two conductors of an electrical cord in the electrical cord straightening device 1. This embodiment may allow for a simpler construction of the electrical cord straightening device 1, because the first portion 10 and second portion 12 do not need to be manufactured so that only the raised regions 17, 17′ do not meet in the closed position as shown in FIGS. 1 a and 1 b.
FIG. 3 shows an exemplary embodiment of the invention in which the pair of grooves 15 each includes at least one ball bearing 30. Only half of the electrical cord straightening device 1 is shown in FIG. 3 for clarity. It is understood that the portion shown in FIG. 3 may correspond to either the top portion 10 or the bottom portion 12. In addition, both or either of the top portion 10 or the bottom portion 12 may include ball bearings 30 in the pair of grooves 15. The ball bearings 30 are positioned in the pair of grooves 15 so that more of the ball bearing 30 is located below the surface of the groove than above. In this manner, the ball bearings 30 are integrated into the grooves and stay in place, but are still free to rotate. The ball bearings 30 act to reduce the stress placed of the conductors and insulation of the electrical cords when the electrical cord straightening device 1 is run down the length of the electrical cord. It is understood that the surfaces of the grooves may be coated with a suitable material in order to reduce the friction between the electrical cord and straightening device, and thereby reduce the stress on the electrical cord. It is understood that the electrical cord straightening device does not straighten the electrical cord by pulling the electrical cord, instead the grooves and more particularly the raised region between the grooves acts to straighten the cord as the straightening device is drawn along the electrical cord.
FIGS. 4 a and 4 b show another exemplary embodiment of the electrical cord straightening device. The device may include a first portion 110 and a second portion 112. The first portion 110 may include one or more pair of grooves 115′. Each groove in the pair of grooves 115′ may be separated by a raised region 117′. The second portion 112 may also include one or more pair of grooves 115 positioned substantially parallel to the pair of grooves 115′ on the first portion 110, so that when the first portion 110 and the second portion 112 are brought into a closed position a tunnel is formed by the pairs of grooves 115, 115′. The hinge mechanism 114, 114′ of the embodiment of the electrical cord straightening device shown in FIGS. 4 a and 4 b may be formed integrally with the first portion 110 and the second portion 112.
As shown in FIG. 4 a, the second portion 112 may include a protrusion 114 extending from the surface on which the one or more pair of grooves are located. The protrusion may include at least one hole 120 extending from one side of the protrusion 114 to the other side. The protrusion 114 on the second portion 112 may be configured to couple with an indentation 114′ on the first portion 110 as shown in FIG. 4 b. The side of the first portion 110 that contains the indentation 114′ may include a hole 121 that substantially aligns with the hole 120 in the protrusion 114 when the indentation 114′ is inserted into the protrusion 114. Holes 120, 121 also a rod or pin (not shown) to be passed through the first portion 110 and the protrusion 114 on the second portion 112 in order to couple the first portion 110 with the second portion 112. This combination allows the first portion 110 and the second portion 112 to operate between an open position and a closed position in a clam-shell like fashion. The edge of the first portion 110 with the indentation 114′ may be rounded to facilitate opening and closing of the electrical cord straightening device. The pairs of grooves 115, 115′ may also have a tapered edge 122, 122′ on at least one side of the first portion 110 and second portion 112 respectively.
FIG. 5 shows an exemplary embodiment of the electrical cord straightening device integrated into a hair brush 300. The electrical cord straightening device may include a first portion 210 and a second portion 212 coupled by a hinge mechanism 214. The first portion 210 and the second portion 212 may include at least one pair of grooves, for example pair of grooves 215 on the second portion 212. The pair of grooves 215 may be positioned on the rounded face of the second portion 212, and the hinge mechanism 214 may be positioned on the flat sides of the first portion 210 and the second portion 212. The integration of the electrical cord straightening device onto the hair brush 300 allows a user easy access to the electrical cord straightening device when using common household appliances such as hair dryers and straightening irons. It is understood that the electrical cord straightening device may be integrated into any object, and that the hair brush 300 is merely exemplary.
It is understood that the electrical cord straightening device may be made from any suitable material, and preferably a non-conductive material, such as wood, plastic, vulcanized rubber, or the like
It is to be understood that all of the present figures, and the accompanying narrative discussions of corresponding embodiments, do not purport to be completely rigorous treatments of the invention under consideration. It is to be understood that the above-described arrangements are only illustrative of the application of the principles of the present invention.
