The material of the housing structure may be comprised of any suitable material, including plastics, metals, and any other material commonly used in the manufacture of household beauty products. Theopening 105 may be provided on the top and the bottom of thehousing 101, thereby allowing the user to access the gears from either side. Further, thehousing 101 may be provided with a protective or decorative cover, which may be used for aesthetic purposes or to cover seams or other parts of thehousing 101 in which hair may potentially become caught. - In various embodiments, the
handle 102 may be formed with thehousing 101 or as a separate element which is attached to thehousing 101 at a later time. In some embodiments, the shape of thehandle 102 comprises an ergonomic shape. Thehandle 102 may also comprise an outer surface formed of foam or another suitable substance for creating a comfortable grip, as may be found commonly in the art. - In the embodiment shown in
FIGS. 2A and2C , three sector gears 110 and fourelliptical gears 120 are visible through theopening 105 in thehousing 101. The sector gears 110 are in a shape similar to the profile of a symmetrical apple core in appearance and the elliptical gears are in the approximate shape of an ellipse with two pointed ends. The shape of the sector gears 110 andelliptical gears 120 are complementary, such that by adding the pointed "elliptical" shape of an elliptical gear to each side of the sector gears 110, the objects collectively take the approximate shape of a circle. By arranging the gears in an alternating fashion (elliptical, sector, elliptical, sector, etc.), with the center of each gear forming a straight line, (in a vertical direction looking atFIGS. 2A or2C ), the gear arrangement takes the shape of a series of intersecting circles. See alsoFIG. 3A . - The motions of the gears rotate about each of the three pivots 115. Each of the sector gears 110 corresponds to one of the
pivots 115, which is located at the center of each of the sector gears 110. In some embodiments thepivot 115 may comprise a pin or other physical feature at the center of the sector gears 110. Alternatively, thepivots 115 may be formed integral to the sector gears 110. In other embodiments, apivot 115 is merely defined as the location about which the rotation takes place, wherein the motion of the gears is guided, for example, by outer constraints on the movement of the gears, such as a channel defining the outer bounds of the gear set 125. - The
elliptical gears 120 also rotate about one of thepivots 115, but may rotate about any one of the pivots, depending on the relative position of the elliptical gear. Theelliptical gears 120 also rotate about one of thepivots 115, but may rotate about any one of the pivots, depending on the relative position of the elliptical gear. For example,FIGS. 3A-3D demonstrate the relative motion of the gears wherein the gears are rotated about one of thepivots 115 at a time, wherein the arrows show the direction of rotation.FIG. 3A shows the gears in a default position, wherein the gear arrangement takes the shape of a set of intersecting circles, as explained above.FIG. 3B shows a first motion of the gears whereinsector gear 111 is rotated aboutpivot 116;FIG. 3C shows a second motion whereinsector gear 112 is rotated aboutpivot 117; andFIG. 3D shows a third motion whereinsector gear 113 is rotated aboutpivot 118. In some embodiments sector gears 111 and 113 may be rotated simultaneously. By performing these motions in the desired order, the relative position ofelliptical gears 120 may be changed. Note, for example, open space 135 (shaded), which changes position through each ofFIGS. 3A-3D , as these motions are performed in succession. In some embodiments, the sector gears 110 may be rotated in either direction about thecorresponding pivot 115. - In the embodiment illustrated in
FIG. 2C , the motion of the sector gears 110 andelliptical gears 120 is manipulated by threeseparate motors 140. As shown inFIG. 2C , themotors 140 may be in contact with the sector gears when the gears are in the default position (FIG. 3A ). The outlying portions of the sector gears 110 and the perimeter of each of the elliptical gears may include a plurality of teeth. These teeth may then be manipulated by one or more of themotors 140, which may be a worm drive or similar actuator to rotate the gears about any one of thepivots 115 as desired. The teeth of the sector gears 110 of one embodiment of agear set 125 are visible inFIG. 3E . - Other motors and arrangements of motors relative to the gears are further contemplated by this disclosure, as may be apparent to one of ordinary skill in the art. For example, in some embodiments, the
motors 140 may be rotary in nature and connected to one of thepivots 115, either directly or by some other mechanical device such as a drive belt, thereby turning the respective gears. In this alternative example, the sector gears 110 andelliptical gears 120 may be toothless. In this respect, the use of the term "gear" within the present disclosure may be construed to include a plurality of moving parts which may result in a similar motion. - In one alternative embodiment, the hand-held
device 100 of the present disclosure may comprise onemotor 140 which provides power to drive each of the sector gears independently. This alternative arrangement may be achieved using, for example, a clutch for each of the rotating sector gears, wherein the controller operates the engagement of each clutch. - The present disclosure further includes alternative embodiments comprising expanded gear sets with the ability to handle more than four strands of hair or filaments. One alternative embodiment is shown in
FIG. 4A , wherein the gear set 225 comprises five sector gears 210 and sixelliptical gears 220, in a linear arrangement. Similarly, other linear arrangements may be devised comprising "n" sector gears and "n+1" elliptical gears.FIG. 4B illustrates another embodiment of the present disclosure, wherein gear set 325 has 12 elliptical gears arranged around four sector gears. This embodiment is therefore able to weave up to 12 strands of hair or filament at one time.FIG. 4C illustrates another embodiment comprising agear set 425 arranged in a triangular formation, having seven elliptical gears and three sector gears. Further embodiments with numerous potential arrangements are also contemplated by the present disclosure, as may be apparent to one having ordinary skill in the art. - As discussed above, the
elliptical gears 120 comprise a hollow center for carrying strands of a flexible material. In some embodiments, the hair-braiding device of the present disclosure comprises a plurality ofsleeves 130, which fit into the hollow center of the correspondingelliptical gears 120. Thesleeves 130 are formed from a flexible material that may be removed from the elliptical gears and replaced. Thesleeves 130 may be used to assist in bundling the flexible material into strands (including bundles of individual strands). Thesleeves 130 may also be configured to preserve tension on the strands without requiring additional work from a user. This may be accomplished by selecting a tactile material for thesleeves 130. -
FIG. 5 illustrates another embodiment of the present disclosure, wherein thesleeves 530 may be constructed with asurface 535 that substantially fills the hollow space within the elliptical gears. In the embodiment shown inFIG. 5 , thesleeve 530 further includes aslot 536, through which the strands may be inserted. Thesleeve 530 should be formed of a flexible material, wherein slot 536 exhibits some elastic properties, thereby accommodating various sizes of strands. The elastic properties ofsleeve 530 also help to create tension on the strands when in use. - The present disclosure may be implemented using a variety of mechanisms to hold the strands in place while operating the hand-held
device 100. In a further embodiment, for example, thesleeves 130 may be replaced by individual clasps that hold the individual strands in the hollow center portion of the elliptical gears 120. Alternatively, the clasps may be provided at the free end of the strands. - Referring again to
FIG. 2C , thecontroller 170 sends signals to each of themotors 140, which turn the sector gears 110, thereby rearranging theelliptical gears 120 and the respective strands which pass through the elliptical gears, resulting in the formation of the desired braid. In some embodiments themotors 140 can be controlled to operate in a number of different sequences, each one forming a unique braid. Further, the operation of the motors may be changed from one pattern to another after a specified number of turns, thereby forming a series of alternating braid patterns in the strands of hair or filaments. The hair-braidingdevice 100 may also comprise a number ofsensors 145, which allow the controller to sense the rotation of the gears. In some embodiments, the controller comprises a processor. - The various braiding patterns discussed above may be stored, for example, as a pattern module comprising a set of instructions. For example, the
memory unit 180 may be provided with free space thereon, whereby additional or new patterns may be loaded onto thememory unit 180 and stored therein. Thecontroller 170 may recall any of the stored braiding patterns via user input. Referring again toFIG. 2B , the user input may be provided via theuser interface 150. Theuser interface 150 may be a simple switch or dial or may be provided as a graphical user interface (GUI), as shown, wherein the GUI comprises a touchscreen. In alternative embodiments, the functions of the user interface may be fulfilled using an external computing device, such as a smart phone, or a computer. - In some embodiments, the pattern modules may be stored in the memory unit using a number of different methods. For example, the user may provide new patterns for the hair-braiding
device 100 by uploading them into the device or by using the GUI. Patterns may be uploaded, for example, usingconnector 185, which may be configured to receive a communications cable, such as a USB interface. Alternatively, the patterns may be uploaded wirelessly, using a suitable communication protocol, such as Bluetooth, Wi-Fi, infrared transmission, or some other type of communication. - The
actuator 160 allows the user to control the starting and stopping of the motor without disrupting the overall set of instructions being executed by thecontroller 170. Theactuator 160, which may alternatively comprise a trigger, button, lever, or switch, allows the user to have direct control over the device. Theactuator 160 may further include a spring. In some embodiments, theactuator 160 comprises multiple settings to control the speed of the gears. This may be controlled, for example, based on the amount of force placed on theactuator 160. Also, theactuator 160 may comprise a sliding selector, which may be moved laterally to control the speed of the output. - The hair-braiding
device 100 further comprises apower source 190, which provides electrical power to the various parts of the device. The power source may comprise a battery, an AC connection, and/or theconnector 185. The power source may comprise a rechargeable battery in connection with an AC connection and/or power from theconnector 185. InFIG. 2C , the embodiment is shown with thepower source 190 residing inside thehandle 102. In other embodiments, thepower source 190 may be located within thehousing 101 or external to thedevice 100. - In operation, the hair-braiding
device 100 of the present disclosure may be used as part of a method for intertwining multiple strands of a flexible material in various braid patterns. In one embodiment, shown inFIG. 6A , the method comprises separating four strands 601 (wherein a strand may be a bundle of individual hairs, filaments, or other flexible material). This flexible material may include flexible metallic elements, fibrous elements, human or animal hair (such as a horse's tail), animal skins, textiles, or any other flexible material that the user may desire to weave. Alternatively, where the strands comprise a bundle of flexible material, the bundle may be temporarily held together with a rubber band or a small strip of paper, as is commonly known in the art. - In
FIG. 6B , thestrands 601 are shown being inserted into thesleeves 130. Referring toFIG. 6C , once each of the strands are placed into the sleeves, thesleeves 130 are placed in the hair-braidingdevice 100 at the center of the elliptical gears 120 (not shown). Alternatively, the strands may be placed directly into the elliptical gears without thesleeves 130 or the sleeves may be left in theelliptical gears 120 while the strands are inserted. - Next, the user selects the desired pattern and begins operating the hair-braiding
device 100 usingactuator 160.FIG. 6D illustrates the weaving action of the hair-braidingdevice 100 when in use. The resulting braid will have a more aesthetic appearance where the correct amount of tension is placed on eachstrand 601. In some embodiments, this tension is provided by thesleeves 130, as discussed above. Finally, once the weaving action is complete, the hair-braidingdevice 100, including thesleeves 130, is removed from the ends of the strands. - Referring to
FIG. 6E , the resulting weave or braid is then secured. In some embodiments, the woven strands may be secured by using atie 602, which may be a ribbon or an elastic band. Alternatively, the woven strands may be secured by singeing, by use of an adhesive, or by another known method. - Referring to
FIG. 7 , another aspect of the present disclosure provides amethod 700 for selecting a desiredpattern module 701 for use with a hair-braiding device in accordance with the present disclosure. As with the various embodiments discussed above, the hair-braidingdevice 100 may be employed in connection with many other flexible materials in addition to hair. Apattern 701 may be located on aninternet server 705, on acomputing device 710, (such as a smart phone, tablet, or computer), or on areadable media device 755, (such as, for example, a flash drive, a memory card, a cartridge, or some other proprietary or commonly used design). Thepattern module 701 may be downloaded from theinternet server 705 to thecomputing device 710, or from thecomputing device 710 to thereadable media device 755. Thepattern module 701 may be stored in thememory unit 735 of the hand-helddevice 720, or it may be loaded directly into thecontroller 730. The storing or loading of thepattern module 701 may be accomplished using wireless communication, as described above, or through a connector, such ascable connector 740 orreadable media connector 750. Where a plurality ofpattern modules 701 are stored on thememory unit 735, the desiredpattern module 701 may be selected using theuser interface 725. Alternatively, the function of theuser interface 725 may be performed using thecomputing device 710.
