One heating element 506 may comprise a heating element distal end 557.
It is contemplated that throughout the application, the term “coupled” or any other similar term may refer to attaching distinctly individual items to one another through a coupling mechanism such as, but not limited to, a nut/bolt system, magnetic coupling mechanism, or any other system known in the art. The term “integrate” or any other similar term may refer to a single unitary embodiment, where appropriate.
Turning now to FIGS. 8A-8D, seen are cross-sectional views taken of the second blade section 904 at varying locations seen in FIG. 9. For example, FIG. 8A shows the cross-sectional view of line 8A-8A in FIG. 9, located proximal the pivoting device 917. As seen in FIG. 8A, the inner blade surface 819 of the second blade section 804 along line 8A-8A is a substantially flat inner blade surface extending from a first outer surface location 823 to a second outer surface location 827. At least a portion of the first blade section 802 may comprise a correspondingly similar inner blade surface 819 and outer blade surface 877 as those shown in FIGS. 8A-8D. Turning now to FIG. 8B, seen is a cross-sectional view of line 8B-8B of FIG. 9. As seen, instead of extending from the first outer surface location 823 of FIG. 8A the inner blade surface 819 along line 8B-8B in FIG. 9 extends from a third outer surface location 829. The third outer surface location 829 is located counter-clockwise circumferentially as compared to the first outer surface location 823 in FIG. 8A. Additionally, a tip of a device fin 840 may be formed at cross-section 8B-8B. Furthermore, the second outer surface location 827 has changed relative to FIG. 8A to the fourth outer surface location 831, with the fourth outer surface location 831 being located at a counter-clockwise circumferential distance from the second outer surface location 827. There may also be a curve 833 in the inner blade surface 819 near the fourth outer surface location 831. As seen in FIG. 8C, along cross-sectional line 8C-8C in FIG. 9, the device fin 840 is larger and there is a smaller curve 833 in the inner blade surface 819, while at section 8D-8D, the full length 853 and size of the fin 840 is present and the inner surface 819 extends from an inner fin base 837 to a fifth outer blade surface 839 in a substantially flat manner. A similar cross-sectional view as the view seen along line 8D-8D may also be found to about the proximal device end 901 in one embodiment.
Returning now to FIG. 1, one device 100 may be used to straighten curly hair and to curl straight hair by sliding hair through the device 100 from about the base of the hair at or near the scalp to the end of the hair at or near the tips, or wherever the sliding motion begins and ends along the length of the hair. Seen in FIG. 2 is one embodiment of the device 200 being used with a first method to straighten hair 220. In order to implement the FIG. 2 method to straighten hair, and as seen in FIGS. 7A-7D, a user may first change the device 700 from the substantially closed position seen in FIG. 7A to an of the first, second or third open positions seen in FIGS. 7B-7D, respectively, in order to place hair between the heating elements 506, as seen in FIG. 5. In moving the device 700 from the substantially closed position seen in FIG. 7A to one of the open positions seen in FIGS. 7B-7D, the first blade section 702 and/or the second blade section 704 may pivot about a distal device end 251, using a pivoting device 217 as seen in FIG. 2.
As seen in the first open device position of FIG. 7B, the proximal end 701 of the device 700 may be aligned to an x-y co-ordinate system. In opening the device 700, the first blade section 704 and the second blade section 702 may be separated by a first x-distance 707 and a first y-distance 709 at the proximal end 701. The angle 711 at which the two sections separate, as seen in the second open device position of FIG. 7C may be determined by the angle 713 which the pivoting device 717 is one of coupled and integrated to at least one of the first blade section 702 and the second blade section 704, as seen in the third open device position of FIG. 7D. For example, the angle 713 may be the angle at which the distal end 251 rotates relative to an extension surface 747. One extension surface 747 may comprise an inner surface on fin 740 and may be substantially perpendicular to an outer surface of the heating element 706 on the second blade section 704. One heating element outer surface 569 may be seen in FIG. 5, with the FIG. 5 heating element outer surface 569 comprising a first section 502 heating element 506. It is also contemplated that at least one of the one or more fin dimensions (length, thickness, etc.) and the angle 711, 713 may affect one or more curl features such as, but not limited to size, shape, direction, fullness, etc.
Upon opening the device 700 to, for example, the position seen in FIG. 7D, a person's hair such as, but not limited to the hair 220 seen in FIG. 2 may be placed between the first blade section 202 and the second blade section 204 and the device 200 may be returned to the closed position seen in FIG. 7A. In one method, the device 200 may be placed at or near a first end 212 of the hair 220, wherein the first end 212 of the hair 220 comprises a hair end proximal a person's head or scalp. The hair may extend away from the person's head and through the first opening 110 of the device, as seen in FIG. 1. The hair may then extend between the heating element pair 106 and exit the device 100 through a second opening 130. Returning now to FIG. 2, upon placing the hair 220 in the device 200 in such a manner, the device 200 may then be pulled away from the person's head and towards a second end 214 of the hair. One second end of the hair comprise and end of the hair 220 distal a person's head. In one embodiment, the first opening 210 may be placed in a vertically upward position, as seen in FIG. 2
Moving the hair 220 through the device 200 in such a manner—first between the heating elements 206 and then proximal the inner surface 867 of the fin 840 as seen in FIG. 8D may straighten a person's hair—thereby changing hair from curly or wavy hair to substantially or generally straight hair. As seen in FIG. 1, as the hair travels next to the fin 140, the hair may be pressed against the fin by an outer portion 149 of the first blade section 102. Straightening the hair 220 with the device 200 is performed by applying heat to the hair 220 prior to the device fin 140 contacts the hair 220. As seen in FIG. 1, the fin 140 may be integrated to an outer surface 177 of the second blade section 104 and extends substantially perpendicularly away from the second bade section heating element 106. However, other angles are also contemplated.
Turning now to FIG. 3, seen is an example of curling hair in a first direction, wherein one first direction comprises curling hair in a direction towards a person—where the curls open towards a person's head. Similar to the FIG. 2 method of straightening a person's hair with the device 200, in the FIG. 3 method of curling a person's hair 320 with the device 300, the device 300 may first couple to the hair at or near the first end 312 of the hair. However, in contrast to the straightening method of FIG. 2, the hair may enter the device 300 through the second opening 130 seen in FIG. 1, extending between the heating element pair, and exit the device 100 through the first opening 110 with the first opening 110 facing the person, as seen by the first arrow 341 in FIG. 3. Upon placing the hair 320 in the device 300 in such a manner, the device may then be pulled away from the person's head and towards the second end 314 of the hair 320 in the direction seen by the second arrow 343. Pulling the device 300 away from the head moves the hair 320 through the device 300, which may curl a person's hair—thereby changing hair from substantially or generally straight hair to substantially or generally curly or wavy hair. Curling the hair 320 with the device 300 is performed by applying heat to the hair 320 after the hair 320 enters the second opening 330 and contacts the device fin 140, as seen in FIG. 1.
Turning now to FIGS. 4A and 12, seen is an example of curling hair 420, 1220 in a second direction, wherein one second direction comprises creating hair curls where the curls fall away or open away from a person's head. Similar to the FIG. 3 method of curing a person's hair with the device 300, in the FIGS. 4A and 12 method of curling a person's hair 420, 1220 with the device 400, 1200, the hair 420, 1220 to be curled may be placed in the device 400, 1200 between the heating elements 106 seen in FIG. 1, at or near the first end 412, 1212 of the hair. Further similar to the curling method of FIG. 3, the hair 420, 1220 may enter the device 400, 1200 through the second opening 430 seen in FIG. 4B, extending between the heating element pair, and exit the device 400 through the first opening 410. The second opening 430 may be facing away from the person in FIGS. 4A and 12, as seen by the first arrow 441, 1221. Therefore, the direction of the second opening 430, 1230 in the FIGS. 4A and 12 method may oppose the direction of the second opening 330 in the FIG. 3 method. In one embodiment, the direction of the curl may be dependent upon the direction of the second opening 430, 330, 1230. For example, in the FIGS. 4A and 12 method, the second opening 430, 1230 may open away from a person and creates curls in a similar direction, which opposes the direction of the curls with the FIG. 3 method—towards the person. Therefore, it is contemplated that additional curl directions beyond towards a person and away from a person as seen in FIGS. 3, 4A, and 12, respectively, are contemplated. In FIGS. 4A and 12, upon placing the hair 420, 1220 in the device 400, 1200 in such a manner, the device 400, 1200 may then be pulled away from the first end 412, 1212 of the hair and towards the second end 414, 1214 of the hair 400, 1200 in the direction shown by the second arrow 443, 1243, thereby sliding the hair through the openings 410, 1210 and 430, 1230. FIG. 4B comprises a close-up of the placement of the device 400 when the FIGS. 4A and 12 method are undertaken. The position of the device seen in FIG. 4B may comprise a second device position.
