DETAILED DESCRIPTION

[0013] A hair brush 10, 210, 310 according to the present disclosure may be used with a blow dryer or other heating tool to style a person’s hair such that the hair is shaped as a desired wave/curl (i.e.: beach wave curls, irregular curls, etc.). The hair brushes 10, 210, 310 each include a handle for a person to grip in his/her hand and a brush head to brush and shape the hair of the person. The hair is shaped using a heating tool in combination with the two components of the brush head 14, 214, 314: the hair-shaping guide 38, 238, 338 and the bristles. The hair-shaping guide 38, 238, 338 may be shaped in a variety of ways such that a diverse range of waves/curls may be achieved using the hair brush 10, 210, 310.

[0014] The shape of the hair-shaping guides 38, 238, 338 create a desired wave/curl in the person’s hair when heat is applied. In the illustrative embodiments, the hair-shaping guide 38, 238, 338 may be provided by a hollow shell. The bristles 60, 260, 360 are located inside of the hollow shell and extend through holes formed in the hollow shell. This allows the bristles 60, 260, 360 to grip the hair so that the hair comes into contact with the hollow shell and remains in contact with the hollow shell throughout heating.

[0015] To shape the hair, a person wraps a section of hair around the brush head 14, 214, 314 so that the bristles 60, 260, 360 grip the hair and the hair is positioned on the hollow shell. The user then applies hot air from a blow dryer onto the hair wrapped around the brush head 14, 214, 314. After a desired length of time, the user removes the hot air from the hair wrapped around the brush head 14, 214, 314 and unwraps the hair from the brush head 14, 214, 314. The hot air from the blow dryer and the unique shape of the hair-shaping guide style the hair in a desired wave/curl so that the wave/curl is maintained even after unwrapping the hair from the brush head.

[0016] The hair-shaping guide 38, 238, 338 provided by the hollow shell creates the wave/curl based on the shapes used to form the hollow shell. To explain, the hollow shell may include circular or partially-hemispherical bulbs 48 connected by necks 50 that are smaller than the bulbs 48. The difference in the sizes of the bulbs 48 and necks 50 shape the hair so that the sections of the hair that are in contact with the bulb 48 when heated create a larger curl/wave than the sections of hair in contact with the necks 50 when heated. This creates the desired curl/wave in the treated section of hair. The bulbs 248, 348 and necks 250, 350 of the hollow shell may also be formed as diamonds, rectangles, and other known shapes and combinations thereof as suggested in

Figs. 5 and 6.

[0017] Turing to Fig. 1 of the drawings, a hair brush 10 according to the present disclosure is adapted to shape a person’s head of hair when hot air is applied on the hair brush 10 and the person’s head of hair wrapped around the hair brush 10. Illustratively, the hot air is produced by a heat source (not shown) (i.e.: blow dryer). The hair brush 10 includes a handle 12 and a brush head 14, as shown in Fig. 1. The handle 12 may be made of a variety of materials configured to withstand residual heat applied on the handle 12 upon heating the brush head 14 via the heat source. The brush head 14 is coupled to the handle 12 and configured to removeably couple to a plurality of hairs (not shown) included in a person’s head of hair so to shape the plurality of hairs using the heating tool.

[0018] The handle 12 is illustratively shaped to be held in a hand of a user as shown in Figs. 1 and 4. The handle 12 is a monolithic, one-piece component formed separate from the brush head 14 and formed to include a grip 18 at a distal end 20 and a mount 22 at a proximal end 24. The mount 22 interconnects the grip 18 and the brush head 14 as best shown/suggested in Figs. 1 and 4. The grip 18 defines a primary/central axis 26. The mount 22 is shaped to fit within the brush head 14 such that a substantial portion of the mount 22 is positioned inside of the brush head 14 prior to coupling the handle 12 to the brush head 14. Such coupling may be achieved in a variety of manners. Illustratively, the mount 22 is formed to include a coupling means 28 configured to couple the brush head 14 and the handle 12 at the mount 22. The coupling means 28 includes a rod receiver 30 and a plurality of fastener holes 32 formed in the mount 22 of the handle 12. The rod receiver 30 is illustratively formed in a substantially vertical manner along the primary axis 26 and configured to receive a portion of the brush head 14. The fastener holes 32 are formed in an outer wall 34 of the mount 22 and configured to receive a plurality of mount fasteners 36. Illustratively, the fasteners 36 are threaded screws configured to be received by the plurality of fastener holes 32 after the brush head 14 has been placed on the mount 22 as shown in Fig. 1.

[0019] The brush head 14 is illustratively formed independent of the handle

12 such that prior to coupling, the brush head 14 and the handle 12 are distinct from one another. The brush head 14 includes a hair-shaping guide 38 and a hair- engagement portion 40 as best shown in Fig. 4. Illustratively, the hair-shaping guide 38 is formed from a continuous hollow shell 46 and shaped such that the hair- engagement portion 40 fits substantially within the hair-shaping guide 38 as shown in Fig. 1. The hollow shell 46 forms an interior space 47 defined by an outermost surface 49 of the hair-shaping guide 38. Therefore, the hair-engagement portion 40 is located inside of the hair-shaping guide 38 within the interior space 47. Further, the hollow shell 46 has a substantially constant thickness between the interior space 47 and the outermost surface 49 of the hair-shaping guide 38.

[0020] The hair-engagement portion 40 of the brush head 14 is configured to removeably engage the plurality of hairs such that the hairs are guided into engagement with the hair-shaping guide 38. Illustratively, the two separate components of the brush head 14 are maintained in such a position via a retainer 37 located at an upper end 39 of the hair brush 10 such that the hair-engagement portion 40 may not be removed from within the hair-shaping guide 38 without first removing the retainer 37 and the hair-shaping guide 38 itself. Further, the hair-engagement portion 40 is coupled to the mount 22 of the handle 12 independent of the hair shaping guide 38 at a lower end 41 of the hair brush 10 and the hair-shaping guide 38 is coupled to the mount 22 of the handle 12 independent of the hair-engagement portion 40 at a lower end 41 of the hair brush 10.

[0021] The hair-shaping guide 38 is designed to engage the plurality of hairs when the hair-engagement portion 40 is removeably coupled to the plurality of hairs. The hair-shaping guide 38 is formed to include a mount portion 44 coupled to the handle 12 along the primary axis 26, a retainer portion 42 spaced apart from the mount portion 44, and a central portion 43 extending between the mount portion 44 and the retainer portion 42 along the primary axis 26. The hair-shaping guide 38 further includes a plurality of bulbs 48, a plurality of necks 50, and a mount receiver 52 as shown in Fig. 4. The bulbs 48 are spaced apart from one another along the central axis 26 extending along the central portion 43 from the retainer portion 42 to the mount portion 44 and are interconnected by the necks 50. Illustratively, the necks 50 and the bulbs 48 are positioned such that the necks 50 extend between a pair of bulbs 54 spaced apart from one another along the central axis 26 such that each bulb

54 is coupled to at least one neck 50. The mount receiver 52 is coupled to a neck 50 and located at the mount portion 44 of the hair-shaping guide 38 and configured to couple the hair-shaping guide 38 to the mount 22 of the handle 12 via a plurality of fastener apertures 35 formed in the hollow shell 46 of the hair-shaping guide 38.

[0022] The plurality of bulbs 48 are designed to engage and shape the plurality of hairs into a desired shape with the use of directed, heated air. To withstand such heat, the bulbs 48 are formed from metallic or ceramic-containing materials suitable for heating by the heating source. The resulting shape of the hairs is dependent upon the shape and size of the bulbs 48 and the necks 50. Therefore, a variety of shapes and degrees of curliness may be produced using the hair brush 10 (i.e.: curls of varying tightness, waves, kinks, coils, etc.).

[0023] To explain, each bulb 48 and each neck 50 include a diameter 56, 55 as shown in Fig 2. Illustratively, the bulb diameter 56 is larger than the neck diameter

55 such that a desired arc length of a curl/wave in the plurality of hairs may be achieved. Further, in increasing the size of the bulb diameter 56 and/or decreasing the size of the neck diameter 55, the arc length of the curl/wave increases thereby resulting in a larger curl/wave. In contrast, increasing the diameter of 55 of the neck 50 and/or decreasing the diameter 56 of the bulb 48 results in a decrease of the arc length of the curl/wave thereby resulting in a smaller wave/curl. Further, the bulbs 48 include a plurality of bristle apertures 33 formed in the outermost surface 49 of the hollow shell 46 forming the bulbs 48. The bristle apertures 33 are spaced apart from one another and extend along the primary axis 26 from the retainer portion 42 to the mount portion 44 of the hair-shaping guide 38. Illustratively, the bulbs 48 are substantially circular. Yet, as will be discussed, the bulbs 48 and the necks 50 may be formed in a variety of shapes as shown in Figs. 5 and 6. [0024] The plurality of necks 50 are designed to interconnect the bulbs 48 and cooperate to engage the plurality of hairs and shape the hairs as desired. Similar to the bulbs 48, the necks 50 are formed from metallic or ceramic-containing materials suitable for heating by the heating source and are also formed to include a plurality of bristle apertures 33 in the outermost surface 49 of the hollow shell 46 forming the necks 50. The bristle apertures 33 are spaced apart from one another extending along the primary axis 26 from the retainer portion 42 to the mount portion 44 of the hair shaping guide 38. The necks 50 cooperate with the bulbs 48 to increase the surface area of the hair-shaping guide 38 such that the plurality of hairs are engaged with both the bulbs 48 and the necks 50 simultaneously. Illustratively, the diameter 55 of each neck 50 is smaller than the diameter 56 of each bulb 48.

[0025] The mount receiver 52 is designed to couple the hair-shaping guide 38 to the handle 12 and is located at the mount portion 44 of the hair-shaping guide 38. The mount receiver 52 is formed to include a plurality of fastener apertures 35 in the outermost surface 49 of the hollow shell 46 which defines the mount receiver 52. The fastener apertures 35 are shaped to align with the fastener holes 32 formed in the mount 22 of the handle 12 so to couple the handle 12 to the hair-shaping guide 38 such that the brush head 14 extends between the distal end 20 of the handle 12 and the retainer portion 42 of the hair-shaping guide 38.

[0026] The hair-engagement portion 40 is configured to removeably couple to the plurality of hairs and guide the hairs into engagement with the hair-shaping guide 38 as shown in Fig. 1. The hair-engagement portion 40 includes a bristle-support rod 58 extending along the central axis 26 and a plurality of bristles 60 coupled to the bristle-support rod at a first end 61 of each of the bristles 60 such that the free end 63 of each bristle 60 extends away from the bristle-support rod 58. The hair-engagement portion 40 is at least partially housed within the hair-shaping guide 38 such that the bristle-support rod 58 is positioned in the interior space 47. Illustratively, the first end 61 of each bristle 60 is also positioned in the interior space 47 such that the free end 63 of each bristle 60 extends through the bristle apertures 33 formed in the hair shaping guide. [0027] The bristle-support rod 58 is shaped to fit within the hair-shaping guide

38 and extends vertically along the central axis 26 away from the handle 12. The bristle support rod 58 includes an end portion 62, a middle portion 64, and an attachment portion 66. The end portion 62 is spaced apart from the attachment portion 66 and located within the interior space 47 of the retainer portion 42 of the hair-shaping guide 38. The end portion 62 is coupled to the retainer portion 42 of the hair-shaping guide 38 via a retainer 37. Illustratively, the retainer 37 is either threaded or glued to the applicable portions 62, 42, although other methods known by those in the art also suffice. The middle portion 64 extends between the end potion 62 and the attachment portion 66. The middle portion 64 is sized to extend the length of the hair-shaping guide 38 and to fit within the hair-shaping guide 38. The attachment portion 66 extends from the middle portion 64 along the central axis 26 towards the handle 12. Illustratively, the attachment portion 66 is coupled to the mount 22 of the handle 12 in the rod receiver 30 formed in the mount 22. The bristle-support rod 58 is coupled to the plurality of bristles 60 at the first ends 61 such that the bristles 60 extend at least the length of the end portion 62 and the middle portion 64. The bristles 60 may further extend along the attachment portion 66.

[0028] The plurality of bristles 60 are, illustratively, planar extensions that extend outwardly from the first ends 61 coupled to the bristle-support rod 58 and extend along the length of the middle portion 64 and end portion 62 of the rod 58.

The bristles 60 are made of materials configured to withstand the heated air applied on the hair brush 10 by the heating tool. Illustratively, the bristles 60 are uniformly sized to extend through the bristle apertures 33 formed in the hair-shaping guide 38 such that at least half of the length of the bristle 60 extends away from the bristle aperture 33. Further, the bristles 60 may vary in length such that not all of the bristles 60 extend the same distance from the bristle aperture 33. Further, the bristles 60 extend outwardly in multiple opposing directions of the rod 58, as shown in Fig. 3. Illustratively, some of the bristles 60 are coupled to the end portion 62 and extend upwardly away from the handle 12. As such, the bristles 60 are coupled to the rod 58 at a variety of angles 74 in multiple opposing directions. Illustratively, the bristles 60 are arranged in clusters 76 along the rod 58 with each cluster 76 including at least two bristles 60. Single bristles 60 may also be coupled to the rod 58. The bristles 60 of each cluster 76, illustratively, extend from the rod 58 at a variety of angles 74 ranging between 30° and 160° relative to the central axis as shown in Fig. 4. Each bristle 60 of the cluster 76 extends through a shared bristle aperture 33 such that more than more bristle, illustratively, extends through each aperture 33 outwardly in multiple opposing directions.

[0029] In the illustrative embodiment, the shape of the hair-shaping guide 38 allows for the hairs to be shaped/styled in a variety of ways. Accordingly, the bristles 60 are configured to engage the hairs such that the hairs comes into contact with the hair-shaping guide 38. Illustratively, the hairs are wrapped around the brush head 14 such that the hairs covers a portion of the brush head 14 and are positioned to lie substantially flat along the outermost surface 49 of the hair-shaping guide 38 before heat is applied.

[0030] According to one method of using the disclosed hair brush 10, a person can shape/style the plurality of hairs to form a desired shape (i.e. : a wave). At a first step of shaping the hairs, the user holds the hair brush 10 at the handle 12 of the hair brush 10. The user then wraps a plurality of hairs around the brush head 14 by engaging the bristles 60 with the hairs, at the wrapping step. At step three, the user applies heat by directing hot air from a heat source (i.e.: blow dryer) on the plurality of hairs and the brush head 14 so to form the hairs in the desired shape. The user then unwraps the plurality of hairs from around the brush head 14 after heat has been applied, at the unwrapping step. The method may further include repeating the first four steps upon a different plurality of hairs until a desired portion of the person’s head of hair is shaped to include a desired arc length of the curls/waves, at a fifth step. Additionally, the wrapping step may include simultaneously rotating the hair brush 10 in an engaging direction around the primary axis of rotation 26 towards the person’s head of hair to secure the plurality of hairs to the bristles 60 extending from the hair shaping guide 38 included in the brush head 14. The wrapping step may further include holding the hair brush 10 such that tension is placed on the plurality of hairs before heat is applied so that at least a portion of the plurality of hairs are in contact with the hair-shaping guide 38 before heat is applied. The unwrapping step may also include removing the plurality of hairs from the brush head 14 by rotating the hair brush 10 in a direction around the primary axis 26 opposite that of the engaging direction thereby removing the tension applied to the plurality of hairs after heat has been applied.
