Heated hair-straightening brush

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.

1 . A hair-straightening brush comprising groupings of protrusions extending from a base, each grouping including at least two heated surfaces positioned to engage user's hair therebetween to modify structure of the hair from curly to straight by moving the brush along the engaged hair. 
     
     
         2 . The hair-straightening brush of  claim 1  wherein the heated surfaces are operatively connected to a heating element disposed within the brush. 
     
     
         3 . The hair-straightening brush of  claim 2  wherein the heating element is configured for cordless operation. 
     
     
         4 . The hair-straightening brush of  claim 2  wherein the heating element is operatively connected to a heated plate on the base, the heated surfaces being defined by heated filaments extending from the heated plate. 
     
     
         5 . The hair-straightening brush of  claim 4  wherein the heated base plate and the heated filaments have ceramic surfaces. 
     
     
         6 . The hair-straightening brush of  claim 4  wherein 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. 
     
     
         7 . The hair-straightening brush of  claim 5  wherein each heated filament has a free end with a heat-insulating cover thereon. 
     
     
         8 . The hair-straightening brush of  claim 1  wherein the heated surfaces are defined by heated filaments extending from the base. 
     
     
         9 . The hair-straightening brush of  claim 8  wherein each of the heated filaments has a free end and a fixed end which is 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. 
     
     
         10 . The hair-straightening brush of  claim 9  wherein, in each grouping, the fixed ends of at least two heated filaments are in contact with each other, the free ends of such heated filaments being closely spaced for passage of the user's hair therebetween. 
     
     
         11 . A hair-straightening brush comprising a base and a plurality of pairs of heated surfaces positioned along the base for engaging user's hair therebetween to modify structure of the hair from curly to straight by moving the brush along the engaged hair. 
     
     
         12 . The hair-straightening brush of  claim 11  wherein the heated surfaces are defined by a plurality of heated strips each defining at least two heated surfaces and each operatively connected to a heating element disposed within the brush. 
     
     
         13 . The hair-straightening brush of  claim 12  wherein the at least two heated surfaces are substantially planar. 
     
     
         14 . The hair-straightening brush of  claim 11  wherein the heating element is operatively connected to a heated plate on the base, the heated strips extending from the heated plate. 
     
     
         15 . The hair-straightening brush of  claim 14  further including non-heated bristles facilitating straightening of the hair. 
     
     
         16 . A hair-straightening brush comprising:
 a plurality of protrusions extending from a base and defining pairs of surfaces positioned to engage user's hair tightly therebetween; and   a heating element operatively connected to the surfaces such that during operation each pair of surfaces is heated to modify structure of the hair engaged therebetween from curly to straight by moving the brush therealong.   
     
     
         17 . The hair-straightening brush of  claim 16  wherein the heating element is configured for cordless operation. 
     
     
         18 . The hair-straightening brush of  claim 17  wherein the heating element is operated by a rechargeable energy source built into the brush. 
     
     
         19 . The hair-straightening brush of  claim 16  wherein the base supports a plate operatively connected to the heating element and is heated during operation, the plurality of protrusions extending from the plate. 
     
     
         20 . The hair-straightening brush of  claim 16  further comprising a handle supporting keys controlling operation of the heating element.
