Hair straightening and curling device

Abstract

A hair straightening and curling device includes two handle arms pivotally extended from a pivot point and two heated plates provided at end portions of the handle arms respectively, wherein each of the heated plates includes a plate body provided at an inner side of the handle arm and a side wing sidewardly extended from the plate body to form a L-shaped plate structure. The side wing is extended out of the sidewall of the handle arm such that the heated plates are adapted for not only straightening a lock of hair when the lock of hair only contacts and sandwiches between the plate bodies but also for curling the lock of hair when the lock of hair further contacts with the side wings.

1 . A hair straightening and curling device, comprising:
 a handle frame comprising two handle arms pivotally extended from a pivot point, wherein each of said handle arms has an end portion defining an inner side and two sidewalls;   a heating arrangement supported at said handle frame; and   a hair ironing arrangement which comprises two heated plates provided at said end portions of said handle arms respectively and operatively linked to said heating arrangement, wherein each of said heated plates comprises a plate body provided at said inner side of said handle arm and a side wing sidewardly extended from said plate body to form a L-shaped plate structure, wherein each of said plate body has a first longitudinal edge extended to said side wing, an opposed second longitudinal edge which is a longitudinal free edge, and a heating surface inclinedly extended from said side wing to said second longitudinal edge of said plate body, such that said heating surfaces are contacted and overlapped with each other for straightening a lock of hair therebetween, wherein said side wings are extended in opposite directions, such that when said handle frame is turned for winding said lock of hair around said end portions of said handle frame, said side wings of said heated plates are arranged for contacting portions of said lock of hair to curl the lock of hair around said end portions of said handle frame.   
     
     
         2 .

         8 . The hair straightening and curling device, as recited in  claim 6 , wherein said side wings are extended oppositely from said plate bodies and said longitudinal free edges of said plate bodies are located oppositely, such that when said heat plates are contacted with each other, said heated plates form a S-shaped configuration for winding said lock of hair therearound. 
     
     
         9 . The hair straightening and curling device, as recited in  claim 1 , wherein said plate body is slantedly provided at said inner side of said handle arm between said two sidewalls thereof at a position that said heating surface of said plate body is inclinedly extended away from said inner side of said handle arm toward said side wing to increase a contacting surface area. 
     
     
         10 . The hair straightening and curling device, as recited in  claim 8 , wherein said plate body is slantedly provided at said inner side of said handle arm between said two sidewalls thereof at a position that said heating surface of said plate body is inclinedly extended away from said inner side of said handle arm toward said side wing to increase a contacting surface area. 
     
     
         11 . The hair straightening and curling device, as recited in  claim 1 , wherein each of said plate bodies has a thickness gradually increasing toward said side wing so as to slantedly form said heating surface of the plate body at said inner side of said handle arm between said two sidewalls thereof. 
     
     
         12 . The hair straightening and curling device, as recited in  claim 10 , wherein each of said plate bodies has a thickness gradually increasing toward said side wing so as to slantedly form said heating surface of the plate body at said inner side of said handle arm between said two sidewalls thereof. 
     
     
         13 . A method of selectively straightening and curling a lock of hair by a hair straightening and curling device which comprises two heated plates at two handle arms respectively, comprising the steps of:
 (a) generating heat at said heated plates;   (b) straightening the lock of hair by the steps of:   (b.1) sandwiching a portion of the lock of hair between two plate bodies of said heated plates; and   (b.2) sliding said heated plates along the lock of hair toward an end thereof; and   (c) curling the lock of hair by the steps of:   (c.1) sandwiching the portion of the lock of hair between said plate bodies of said heated plates;   (c.2) turning said handle arms to wind the lock of hair therearound to contact the portion of the lock of hair with two side wings of said heated plates, wherein said side wing is sidewardly extended from said plate body to form a L-shaped plate structure and is extended out of a sidewall of said handle arm; and   (c.3) sliding said heated plates along the lock of hair toward the end thereof.
