Interactive styling hairbrush

Abstract

A styling brush with vanes that is interactive, which directs and redirects air flow of a hair dryer, is used to improve styling techniques for right-handed or left-handed users. The bristles of the brush may be such that the user's hair floats on a cushion of bristles to speed up drying and protect the user's hair from excessive heat damage.

(17) Turning now to FIG. 1, there is shown a hairbrush 100 having a handle 102 (with or without a demarcated neck) that is connected to a brush head 104. In one preferred embodiment, the handle 102 includes a soft grip. However, other handle shapes and designs may be used without departing from the scope and intent of the present disclosure. In another embodiment, the handle 102 and the brush head 104 are formed at least in part from different materials. In still another embodiment, the brush head 104 includes a substrate from one of wood, metal, or plastic composition. In still another embodiment, the handle 102 and the brush head 104 may be a single, unitary body or structure.

(18) In the illustrated embodiment, the handle 102 is connected to a first enlarged end portion 106 of the brush head 104. In another preferred embodiment, the handle 102 is connected to a second enlarged end portion 108 of the brush head 104. In still another preferred embodiment, the handle 102 is configured, alternately, for right-handed or left-handed users.

(19) The brush head 104 of hairbrush 100 includes the axially spaced apart first and second end portions 106, 108 which are interconnected by an intermediate, central portion 110 along an elongated axis. The central portion 110 of the brush head 104 preferably has a generally concave conformation, and thus has a cross-sectional first dimension smaller than a cross-sectional second dimension of the first enlarged end portion 106, and more preferably smaller than a cross-section third dimension of the second enlarged end portion 108. The second and third dimensions of the first and second enlarged end portions 106, 108 are typically substantially the same; however, this need not always be required. The brush head 104 desirably includes arcuate transitions from the first and second end portions 106, 108 into the central portion 110 of the brush head 104, although other transitional conformations could be used.

(20) A series of axially spaced openings 120 are provided in the brush head 104 and adapted to receive bristles 122 that extend through the outer surface 124 of the brush head 104. The bristles 122 have terminal ends 126 that extend radially outward from the outer, external surface 124 of the brush head 104. More particularly, the bristles 122 are preferably arranged in circumferentially spaced rows extending axially from the first end portion 106 to the second end portion 108 of the brush head 104. The bristles 122 in FIG. 1 are shown in circumferentially spaced rows and the rows have a helical twist, i.e., the rows rotate in the circumferential direction as the row proceeds in the axial direction from one end portion toward the other end portion; however, one skilled in the art will appreciate that still other bristle configurations can be used without departing from the scope of the present disclosure. In one preferred embodiment, the alternating rows of bristles 122 have staggered axial dimensions along the central portion 110 of the brush head 104. That is, every other row terminates at a slightly different axial location from the circumferentially adjacent row of bristles. Although the rows of bristles 122 form a helical conformation around the brush head 104, the rows could be linear or have a greater or lesser helical twist, or adopt still another pattern. The bristles 122 usually include bundles of individual bristles tightly bunched together at the outer surface 124 of the brush head 104. The individual bristles diverge outwardly from one another as the bristles 122 extend radially outward from the outer surface 124 of the brush head 104. In another embodiment, the bristles 122 extend from the central portion 110 only and thus terminate at an axial location spaced inwardly from vanes 130 to be described further below.

(21) In one preferred embodiment, the vanes 130 extend radially outward from the first enlarged end portion 106 of the brush head 104. In another embodiment, the vanes 130 extend radially outward from the second enlarged end portion 108 of the brush head 104. In still another embodiment, vanes 130 extend radially outward from the first and second enlarged end portions 106, 108 of the brush head 104. The vanes 130 are fixed on brush head 104 such as by integrally molding the vanes as a part of the material that forms the brush head.

(22) In one preferred embodiment, FIGS. 1 and 2 show vanes 130 extending radially outward from the first enlarged end portion 106 of the brush head 104 that are configured to direct air flow from an associated hair dryer impinging on the hairbrush 100. The vanes direct the air flow in an axial direction along the central portion toward the second enlarged end portion 108 of the brush head. In another preferred embodiment, vanes 130 extending radially outward from the second enlarged end portion 108 of the brush head 104 are configured to direct air flow from an associated hair dryer impinging on the hairbrush 100 in an axial direction along the central portion toward the first enlarged end portion 106 of the brush head 104. The vanes 130 may be curved in shaped to direct channeling of air flow between the rows of bristles 122.

(23) The vanes 130 are configured to direct air flow between the same row of bristles when a user holds the brush 104 in their left or right hand.

(24) With reference to FIGS. 2 and 3, the vanes 130 at one end portion are circumferentially spaced apart and form channels 140 therebetween. In one preferred embodiment, the vanes 130 are spaced apart and terminate adjacent every second row of bristles 122. The vanes 130 preferably vary in radial height from the outer surface 124 of the brush head 104 over an axial dimension. The radial height of the vanes 130 decreases as the vanes 130 extend axially toward the central portion 110 of the brush head 104 and the vanes 130 merge into the outer surface 124 of the brush head 104 (merging into the outer surface of the central portion of the brush head adjacent an end of a row of bristles). In one preferred embodiment, the vanes 130 are configured to direct air flow along the brush head 104 between adjacent rows of bristles 122. The vanes 130 terminate in an axial direction adjacent the rows of bristles 122. This allows the vanes to act as a channeling component. In another preferred embodiment, the vanes 130 are fixed on the brush head 104 and continue into the space between the rows of bristles 122. The vanes 130 may be deeper on one side. The vanes are configured to redirect airflow from an associated hair dryer through channels 140 between the rows of bristles 122. The channels 140 may be simply formed as the space defined on the outer surface of the hairbrush central portion between the rows of bristles, and/or may include cuts or grooves formed in the outer surface between the rows of bristles which assist in air flow therethrough. The channeling of air flow continues through the length of the barrel of brush head 104, for example between a second set of vanes provided at the other end portion of the hairbrush.

(25) With reference to FIG. 4, the vanes 130 extend radially outward from the second end portion 108 for directing air flow from an associated hair dryer impinging on the hairbrush 100 in an axial direction along the central portion 110 toward the first enlarged end portion 106 of the brush head, the vanes 130 located on the first enlarged end 106 portion terminate adjacent an end of a first set of bristle rows 122. The vanes 130 located on the second enlarged end portion 108 terminate adjacent an end of a second set of bristle rows. The first set of bristle rows alternate with the second set of bristle rows about a circumference of the central portion 110 of the brush head 104.

(26) In another arrangement, the vanes 130 located on the first enlarged end portion 106 terminate adjacent an end of a first set of bristle rows 122 and the vanes 130 located on the second enlarged end portion 108 terminate adjacent an end of a first set of bristle rows 122 about a circumference of the central portion 110 of the brush head 104.

(27) The hairbrush 100 is an interactive tool designed to be used by a left-handed or right-handed user or stylist. The hairbrush 100 can be configured for either a dominant right-handed user (FIG. 6) or configured differently for a dominant left-handed user (FIG. 7). The vanes 130 create a styling hairbrush 100 that becomes interactive and has the ability to control air flow and heat by redirecting both to the center of the brush head 104 above and below the hair section. The structure of the inventive hairbrush 100 as described above enhances both heat and air flow above and below the hair section while reducing drying time and heat damage to the hair. When using a typical hairbrush with a hair dryer or hair blower, for example, air flow directed toward a conventional hairbrush reflects or bounces in all directions, whereas the present invention provides directional control of the airflow as a result of providing the enlarged or captive end(s) 106, 108 and the preferred shape of the generally concave conformation of the central portion 110 in conjunction with the vanes 130. The vanes 130 provide additional directional control that advantageously speeds up the drying time and directs air below (adjacent the base of the bristles and the external surface of the hairbrush body) and above the hair supported on the ends of the bristles. The vanes aid in directing the air flow along paths or channels formed between the bristles. Still further, with the present invention the hairbrush can be tailored for use as a specific right-hand brush or a specific left-hand brush. These featuresboth individually and collectivelyare a significant improvement over existing, traditional styling hairbrushes that disperse both the air and heat in all directions without the efficient control and structure as are achieved with the hairbrush 100 having the vanes 130. Prior to the present hairbrush with the vanes 130 specifically configured for either a right-handed or a left-handed user/stylist, the same conventional hairbrush was used by either right-handed or left-handed users. Such traditional hairbrushes did nothing to enhance the styling process, and instead were simply a core with bristles with different diameters, and were nonactive during the styling process other than when a user/stylist shapes or smooths hair by manipulating the hairbrush.

(28) Another aspect of the present invention is to provide a hairbrush with more styling features and heat protection features. FIGS. 4 and 5 show hairbrush 100 that includes handle 102, a brush head 104 connected to the handle 102, bristles 122 extending from the outer surface 124 of the brush head 104, rows of bristles 122, and vanes 130. A user's hair 160 is supported on top of a cushion of bristles without coming into contact with the brush head 104. The vanes 130 direct air flow from the associated hair dryer along the brush head 104 underneath the user's hair 160. This enhances the ability to control/style the hair with this hairbrush when compared to prior hairbrush designs. These structural and functional features channel more air flow beneath the central portion of the hairbrush. Another advantage of this is it greatly reduces the drying time and without damaging the user's hair. Because the hair 160 floats on a cushion of bristles, the user's hair has a reduced chance of contacting the hot surface of the hairbrush 100. This also reduces the damage to a user's hair normally caused by heat. The vanes at each end work in conjunction with the enlarged captive ends (i.e., the larger diameter enlarged end portions that are greater in cross-sectional dimension than the narrower central portion of the hairbrush) to channel the air flow from the hair dryer into each end of the hairbrush, into the channels formed between the rows of bristles, and beneath the hair supported on the bristle ends. This allows that section of hair supported by the bristles of the hairbrush to have increased air flow beneath the hair (i.e., radially pass between the outer surface of the brush head and the hair supported on the outer ends of the bristles) during styling so that the hair dries from above and below. This speeds up the drying time without damage to the hair. Again, this arrangement limits direct contact of the hair with the hot surface of the brush head which could lead to hair damage. Further, the thermal conductive technology shown and described in U.S. Pat. No. 10,2922,486 can be used in this hairbrush to provide further temperature control that limits hair damage. The exemplary embodiment has been described with reference to the preferred embodiments. Obviously, modifications and alterations will occur to others upon reading and understanding the preceding detailed description. It is intended that the exemplary embodiment be construed as including all such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
