Device to give volume to the hair that uses individual teeth without leaving a visible pattern

摘要

A device for adding volume to the hair, comprising: a first arm (2) comprising a first interlocking plate (4); a second arm (3) comprising a second interlocking plate (5); at least one heating element associated with any one of said first interlock plate (4) and said second interlock plate (5); and a pivot (7) positioned between said first arm (2) and said second arm (3) and arranged to allow relative movement of the interlocking plates (4, 5) between an interlocked position and a non-interlocked position; each of said first and second interlocking plates comprising a two-dimensional set of individual teeth (10) projecting outward; wherein the set of individual teeth (10) projecting out from the first interlocking plate (4) is interlockingly complementary to the set of individual teeth (10) projecting outward from the second interlocking plate (5). ); characterized in that each individual tooth (10) comprises a flat top surface (13) and either comprises a square prism shape or is a trapezoidal tooth; and why the two-dimensional set of individual teeth (10) comprises a checkerboard pattern in which each individual tooth (10) is surrounded on each of its sides by a space (11) that is dimensioned and has a similar shape to the individual tooth (10).
