Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 40 words
A hair styling instrument comprising a hair shaping board, said board having opposed hair contacting and shaping convex and concave surfaces, means intermediate said surfaces for heating both of said surfaces, a handle for said board, said handle being unheated.
Claim 2
Dependent Claim 40 words
A hair styling instrument comprising a hair shaping board, said board having opposed hair contacting and shaping convex and concave surfaces, means intermediate said surfaces for heating both of said surfaces, a handle for said board, said handle being unheated.
Claim 3
Dependent Claim 75 words
The instrument of claim 1 wherein the hair shaping board has the concave and convex surfaces formed as top and bottom surfaces respectively of a substantially rectangular shaped member, longitudinal edges on said member, said edges having a radius curvature from the top surface to the bottom surface substantially less than the curvature of said surfaces said edges forming second hair contacting and shaping surfaces and being heated along with said convex and concave surfaces.
Claim 4
Dependent Claim 40 words
The instrument of claim 2 wherein a heating coil is embedded in a metal plate forming the hair shaping board and the handle is equipped with a device for regulating the heat imparted to the board by the heating coil.
Claim 5
Dependent Claim 15 words
The instrument of claim 3 wherein the handle is equipped with water dispensing spray means.
Claim 6
Dependent Claim 59 words
The instrument of claim 3 wherein the hair shaping board has a sleeve received at least partially therearound, the sleeve having an underside surface in contact with a surface of the board and an outer surface having a contour different than the contour of the surfaces of the board said outer surface comprising a hair contacting and shaping surface.
Claim 7
Dependent Claim 21 words
The instrument of claim 3 wherein said instrument is equipped with fastening means for attaching the same to a human body.
Claim 8
Dependent Claim 116 words
A hair shaping instrument comprising in combination: a hair shaping board having opposed convex and concave surfaces with longitudinal edges extending between the surfaces, the longitudinal edges formed as radius bends having a radius curvature less than the radius curvature of the convex and concave surfaces, a handle attached to said board means embedded in said board for heating same, means on said handle for regulating the heat of the board, and detachable sleeve means for receipt at least partially around said board, said sleeve means having an outside hair styling surface having a contour different than the contour of the concave and convex surfaces and being heated by contact with the concave and convex surfaces.
Claim 9
Dependent Claim 116 words
A hair shaping instrument comprising in combination: a hair shaping board having opposed convex and concave surfaces with longitudinal edges extending between the surfaces, the longitudinal edges formed as radius bends having a radius curvature less than the radius curvature of the convex and concave surfaces, a handle attached to said board means embedded in said board for heating same, means on said handle for regulating the heat of the board, and detachable sleeve means for receipt at least partially around said board, said sleeve means having an outside hair styling surface having a contour different than the contour of the concave and convex surfaces and being heated by contact with the concave and convex surfaces.
Claim 10
Dependent Claim 30 words
The instrument of claim 7 wherein the handle is quickly detachable from the board, the board having an opening therein for receipt of a heated device attached to said handle.
Claim 11
Dependent Claim 17 words
The instrument of claim 8 wherein thE heated device attached to said handle comprises a heated comb.
Claim 12
Dependent Claim 115 words
A hair shaping instrument comprising a hair shaping board with a length and width and thickness, the length being the major dimension and the thickness being relatively thin, the board arcuately curved transversely having concave and convex opposed smooth surfaces with a handle projecting from the board lengthwise of the board the convex and concave surfaces providing hair contacting and shaping surfaces, longitudinal edges extending the length of the board forming second hair contacting and shaping surfaces, the edges having a radius of curvature from the said convex to the said concave surface substantially less than the curvature of said convex and concave surfaces whereby a thin hair shaping surface is provided by said edges.
Claim 13
Dependent Claim 115 words
A hair shaping instrument comprising a hair shaping board with a length and width and thickness, the length being the major dimension and the thickness being relatively thin, the board arcuately curved transversely having concave and convex opposed smooth surfaces with a handle projecting from the board lengthwise of the board the convex and concave surfaces providing hair contacting and shaping surfaces, longitudinal edges extending the length of the board forming second hair contacting and shaping surfaces, the edges having a radius of curvature from the said convex to the said concave surface substantially less than the curvature of said convex and concave surfaces whereby a thin hair shaping surface is provided by said edges.
