First claim
Opening claim text (preview).
The invention claimed is: 1 . A hair styling appliance comprising: a pair of arms having an open position and a closed position, the arms gripping the hair when in the closed position; a pair of electrodes; a chamber located between the electrodes for receiving a section of hair; and a drive unit for applying an alternating voltage to the electrodes to heat dielectrically hair within the chamber, wherein the electrodes having a fixed spacing and wherein at least one of the arms is moveable to vary a spacing between the arms without varying the spacing between the electrodes. 2 . The hair styling appliance as claimed in claim 1 , wherein the spacing is no greater than 10 mm. 3 . The hair styling appliance as claimed in claim 1 , wherein the spacing is no less than 1 mm. 4 . The hair styling appliance as claimed in claim 1 , wherein the height of the chamber is between 1 mm and 10 mm. 5 . The hair styling appliance as claimed in claim 1 , wherein the electrodes are coated with or housed within a thermally insulating material. 6 . The hair styling appliance as claimed in claim 1 , wherein the appliance comprises a body having a pair of prongs, and each of the electrodes is attached to or housed within a respective prong. 7 . The hair styling appliance as claimed in claim 6 , wherein an end of each of the prongs is chamfered. 8 . The hair styling appliance as claimed in claim 1 , wherein the electrodes are attached to or housed within a body, the arms are attached to the body, and at least one of the arms is moveable relative to the body. 9 . The hair styling appliance as claimed in claim 8 , wherein the at least one of the arms is pivotally attached to the body. 10 . The hair styling appliance as claimed in claim 8 , wherein the appliance comprises a flexible membrane that extends between the body and the at least one of the arms. 11 . The hair styling appliance as claimed in claim 1 , wherein at least one of the arms comprises a gripping portion for gripping the hair, the gripping portion being formed of a resiliently deformable material.
