Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation-in-part of Ser. No. 15/912,439, entitled “VOLUME AND CURL ENHANCING HAIRBRUSH,” filed Mar. 5, 2018, pending, which claims the benefit of provisional Ser. No. 62/466,908, filed Mar. 3, 2017, the subject matter of each of the above incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to hairbrushes, and more particularly to hairbrushes having disparate sets of bristles arranged in particular patterns to enhance volume and curl.

2. Description of the Related Art

Hair has a tendency to become tangled, snarled, and generally untidy if not cared for on a daily basis. Hence various combs and brushes have been invented for hair care. Combs have teeth that are useful for managing hair, particularly when hair is wet or needs to be parted and/or styled. Hairbrushes have bristles that stimulate the scalp, clean the hair, and spread natural oils through the hair.
Conventional hairbrushes include various types of bristles. These include bristles made of plastic, such as nylon. Some of these plastic bristles include balls on the tips. There are also natural bristles made of boar hair or the like, and blends of natural and synthetic bristle. Additionally, there are many different types of hairbrushes, including flat brushes, round brushes, teasing brushes, venting brushes, etc.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, an exemplary hairbrush 100, according to a first embodiment of the present invention, is illustrated. The hairbrush 100 includes a main body 50, a first set of bristles 10, a second set of bristles 20, and a handle 40 extending from the main body, as shown. The main body 50 may be substantially cylindrical, as depicted, or have another suitable shape such that the bristles of the hairbrush are disposed around the main body 50. Preferably, the hairbrush 100 will have bristle sockets, such as bristle socket 30, or the like, arranged along the main body 50 permitting a plurality of bristles to be inserted into each of the sockets. The handle 40 can be any suitable shape or size, preferably providing good grip during usage. Furthermore, the handle 40 can include a hole or similar feature permitting the handle to be mounted to a wall, for example. As will be described in greater detail, unlike conventional hairbrushes that possess only a single bristle type regarding length or material choice and consistency, the present hairbrush 100 through the use of a helical bristle pattern with disparate bristle sets 10, 20, can produce a magnified effect on curl and volume of the user's hair compared to conventional hairbrushes.
FIG. 2 illustrates relative height differences between the first set of bristles 10 and the second set of bristles 20 of the exemplary hairbrush 100, according to the first embodiment of the present invention. As noted the main body 50 of the hairbrush 100 includes a first set of bristles 10 and a second set of bristles 20. As shown, the first set of bristles 10 includes bristles that are on average longer by a distance d than the second set of bristles 20. The first set of bristles 10 can be about 1 inch on average in length and the second set of bristle of bristles 20 are about 1.5 inch on average in length. In this case, the distance d would be about 0.5 inches in length, or about a 50% difference. The distance d can be at least about 0.25 inches.
FIG. 3 illustrates the arrangement of the first set of bristles 10 and the second set of bristles 20 around the main body 50 of the hairbrush 100. As depicted, the first set of bristles 10 and the second set of bristles 20 are shown divided using white lines. It is to be understood that such lines are used herein for illustrative purposes to more distinctly show the first set of bristles 10 and the second set of bristles 20, and do not form a part of the present invention. As mentioned, the first set of bristles 10 and the second set of bristles 20 are each arranged around the main body 50 in a helical pattern. As shown, the first set of bristles 10 and the second set of bristles 20 are disposed immediately next to each other, and it is to be understood that this arrangement carries on all sides of the body 50. It is to be further understood that although side perspective views of the hairbrush 100 are shown, the first set of bristles 10 and the second set of bristles 20 actually each continue around the main body 50 in a helical arrangement. FIG. 4 illustrates a diagram graphically representing a helix 70, presented to aid in understanding the present invention. As shown, the helix 70 winds around an elongated member (in this case a cylinder) 80. A stacked helical arrangement as used herein refers to two such helixes wound around the body of the hairbrush, one helix next to the other.
As shown in FIG. 3, the first set of bristles 10 and the second set of bristles 20 have different types of bristles. In the illustrated embodiment, the first set of bristles includes synthetic bristles such as nylon bristles. These bristles can include some bristles having a ball tip and some that do not. In other variations, natural bristles can further be includes in the first set of bristles 10, but they will not make up a majority of the bristles therein. Notably, the bristles of the first set of bristles 10 are longer and more flexible than those of the second set of bristles. In the illustrated embodiment, the second set of bristles 20 include only natural animal hair bristles, preferably bore bristles, that are more rigid and shorter than the bristles of the first set of bristles 10. By providing such a bristle differential, the first set of bristles 10 reach to the scalp and lift strands of hair up from the scalp, and the second set of bristles 20 then smooth these strands resulting in a magnified volume and curl.
Referring to FIG. 5, an exemplary hairbrush 200, according to a second embodiment of the present invention, is illustrated. The main difference between the hairbrush 200 and the hairbrush 100 is that the body 230 of the hairbrush 200 is not cylindrical and hence the bristles 10, 20 are not arranged along helices; rather, the body 230 of the hairbrush 200 is relatively flat with a central portion 230 on one side having a slight convex surface to accommodate the bristles 10, 20. The bristles 10, 20 are themselves the same as disclosed above. The opposite side of the hairbrush 200 can be smooth and bristleless. As shown, groups of the bristles 10 and 20 alternate in horizontal discrete channels along the central portion 230. The central portion 230 can include an elastic covering such as rubber so that the bristles can be inserted through the covering for support. The body 230 and the handle 40 are preferably constructed of a hard, durable material such as plastic, metal, or wood.
Referring to FIG. 6, an exemplary hairbrush 300, according to a second embodiment of the present invention, is illustrated. The main difference between the hairbrush 300 and the hairbrush 200 is that the body 330 of the hairbrush 300 includes several protrusions 332A, 332B, 332C, and 332D that are separated by gaps 335A, 335B, and 335C, respectively. That is to say, that the body 330 is not a solid piece but rather has voids (air gaps) that separate the protrusions 332A, 332B, 332C, and 332D (though they are united at the handle 40). The opposite side of the hairbrush 300 can be smooth and bristleless. As shown, groups of the bristles 10 and 20 alternate in placement along the protrusions 332A, 332B, 332C forming discrete channels while the central protrusion 332D accommodates alternations of the bristles 10 and 20, as shown. The bristles 10, 20 are themselves the same as disclosed above. The body 330 and the handle 40 are preferably constructed of a hard, durable material such as plastic, metal, or wood.
Referring to FIG. 7, an exemplary hairbrush 400, according to a second embodiment of the present invention, is illustrated. The hairbrush 400 is similar to the hairbrush 200, the main difference being that the bristles 10, 20 are arranged concentrically rather than in rows, as shown. The body 430 of the hairbrush 400 is relatively flat with a central portion 430 on one side having a slight convex surface to accommodate the bristles 10, 20. The concentric arrangement of the bristles 10, 20 can include alternations of the bristles 10, 20 in all or part of the hairbrush surface having bristles forming discrete channels. The bristles 10, 20 are themselves the same as disclosed above. The opposite side of the hairbrush 400 can be smooth and bristleless. As with the other embodiments, the body 430 and the handle 40 are preferably constructed of a hard, durable material such as plastic, metal, or wood.
While this invention has been described in conjunction with the various exemplary embodiments outlined above, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the exemplary embodiments of the invention, as set forth above, are intended to be illustrative, not limiting. Various changes may be made without departing from the spirit and scope of the invention.
