Abstract
A hair-straightening brush comprising a base and a plurality of pairs of heated surfaces positioned along the base closely together to tightly engage user's hair therebetween to modify structure of the hair from curly to straight by moving the brush along the engaged hair. The heated surfaces may be defined by heated filaments extending from the base and operatively connected to a heating element within the brush. In some embodiments, the heated surfaces are defined by heated strips extended from the base and operatively connected to a heating element within the brush.
Description
- The present invention relates to devices for temporarily straightening curly hair and reducing such hair condition commonly known as frizz.
- Straightening one's naturally curly hair typically takes a large amount of time and requires the use of multiple tools. However, naturally curly hair that has been temporary straightened return to the original curly structure when exposed to high humidity. Therefore, it is desirable to have a portable device for straightening hair in the event of exposure to high humidity such as rain, snow or other conditions which cause elevated humidity in the air. It is desirable to have a hair-straightening tool that permits quick retouching of one's naturally curly hair to correct the effects of high humidity and return hair to the desirable straight structure in a brief period of time throughout the day.
- There have been few devices available that have been made with the intention to solve the aforementioned problems. One kind of such devices are small-size cordless straightening irons such as that shown in
FIG. 12 . However, while such devices are portable and readily operable without the need for a power outlet, the use of straightening irons takes a significant amount of time which may not be available to a person with a busy schedule. Some other products that have been advertised as facilitating the straightening of one's hair are simply different kinds of brushes, such as those shown inFIG. 13 . Any of such brushes by itself would not sufficiently straighten naturally curly hair. Some other devices for straightening hair are seen in U.S. Pat. Nos. 1,362,823 and 4,860,775. These devices, however, fall short at allowing quick on-the-go touch up of naturally curly hair to maintain the desired temporary straight structure. - The present invention provides an improved hair-straightening brush including groupings of protrusions extending from a base. Each grouping includes at least two heated surfaces positioned to engage a user's hair therebetween to modify structure of the hair from curly to straight by moving the brush along the engaged hair. The heated surfaces may be operatively connected to a heating element disposed within the brush. The heating element may be configured for cordless operation. The heating element may be operated by a rechargeable energy source built into the brush.
- The heated surfaces may be defined by heated filaments extending from the base. Some embodiments have a plurality of protrusions extending from a base and defining pairs of surfaces positioned to engage user's hair tightly therebetween. The base supports a plate operatively connected to the heating element and is heated during operation, the plurality of protrusions extending from the plate.
- In some embodiments, the heating element is operatively connected to a heated plate on the base. In some of such embodiments, the heated surfaces are defined by heated filaments extending from the heated plate. The base may support the plate operatively connected to the heating element and is heated during operation. In some of such embodiments, the plurality of protrusions extend from the plate. In some versions the plate and the protrusions are formed by a single-piece structure. The heated base plate and the heated filaments may have ceramic surfaces.
- In certain embodiments, each grouping has more than two heated filaments which together define more than one pair of heated surfaces positioned closely together for engaging hair therebetween.
- Each of the heated filaments has a free end and a fixed end. The fixed end may be secured with respect to the base such that the free end is movable with respect to the base, thereby facilitating engagement of the user's hair. Each heated filament may have a heat-insulating cover on the free end. In each grouping, the fixed ends of at least two heated filaments may be in contact with each other. The free ends of such heated filaments are closely spaced for passage of the user's hair therebetween.
- In some embodiments, the heated surfaces are defined by a plurality of heated strips. Each of the heated strips defines at least two heated surfaces and is operatively connected to the heating element disposed within the brush. The heated strips extend from the heated plate.
- In certain versions, the at least two heated surfaces are substantially planar. In some of such versions the heated filaments have a substantially polygonal cross-section with a plurality of substantially planar heated surfaces.
- In some versions, the heated filaments have a substantially cylindrical cross-section.
- The heated base plate and the heated filaments have ceramic surfaces. Some embodiments may further include non-heated bristles facilitating straightening of the hair.
- Some embodiments of the present invention further include a handle supporting keys controlling operation of the heating element.

FIGS. 4 and 6 illustrate some versions of the hair-straightening brush in which eachgrouping 15 includes a set ofnon-heated bristles 26 facilitating straightening ofhair 100. Non-heated bristles 26 may be of a suitable heat-safe materials such as boar hair for separating hair in a strand to facilitate straightening. The inventive brush may also include silicone strips and ion-emitting materials or devices which facilitate flattening of the hair cuticle layer and also reduce frizz. - Each of the heated filaments has
free end 22 and afixed end 23. In some embodiments, fixedend 23 is secured with respect tobase 12 such thatfree end 22 is movable with respect tobase 12 to facilitate engagement of the user's hair. In some of such embodiments, the fixed ends of at least two heated filaments in each grouping are in contact with each other. The free ends of such heated filaments are closely spaced for passage of the user's hair therebetween. - In certain embodiments such as those illustrated in
FIGS. 10 and 11 ,heated surfaces 14 are defined by a plurality of heated strips 19. Each ofstrips 19 defines at least two heated surfaces and each is operatively connected to the heating element disposed within the brush.FIGS. 10 a, 10 b and 11 a-11 e illustrate examples of the at least twoheated surfaces 14B being substantially planar.FIG. 10 c shows an example ofheated strips 19A which define non-planarheated surfaces 14C. - In some embodiments, each heated strip has a fixed end secured with respect to the base and extending therefrom to a free end.
