Abstract
Abstract A hair-grooming device comprises a hollow elongate holder having a comb or brush attachment fitted onto one end portion thereof. A high-voltage source is enclosed in the holder for ion-generation. An elongate conductive support is mounted in and insulated from the holder and electrically connected to the high-voltage source, such support extending parallel to and opposite the attachment. At least one row of electrodes extends outwardly from the support toward the holder. There is a slot-like opening in the holder adjacent the attachment for each row of electrodes, the electrodes in each row extending toward the corresponding opening for escape of the formed ions through such opening to the exterior of the holder.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
111 words
A hair-grooming device comprising a hollow elongate holder; a comb or brush attachment fitted onto one end portion of the holder; a high-voltage source enclosed in the holder for ion-generation; an elongate conductive support mounted in and insulated from the holder and electrically connected to said high-voltage source, said support extending parallel to and opposite the attachment; at least one row of electrodes extending outwardly from said support toward the holder; and a slot-like opening in the holder adjacent the attachment for each row of electrodes, the electrodes in each row extending toward the corresponding opening for escape of the formed ions through such opening to the exterior of the holder.
Claim 2
Dependent Claim
111 words
A hair-grooming device comprising a hollow elongate holder; a comb or brush attachment fitted onto one end portion of the holder; a high-voltage source enclosed in the holder for ion-generation; an elongate conductive support mounted in and insulated from the holder and electrically connected to said high-voltage source, said support extending parallel to and opposite the attachment; at least one row of electrodes extending outwardly from said support toward the holder; and a slot-like opening in the holder adjacent the attachment for each row of electrodes, the electrodes in each row extending toward the corresponding opening for escape of the formed ions through such opening to the exterior of the holder.
Claim 3
Dependent Claim
26 words
A hair-grooming device according to claim 1, in which the free ends of the electrodes in each row project into the corresponding opening in the holder.
Claim 4
Dependent Claim
