Abstract

A hair clipper attachment comb is provided for use with a powered hair clipper having a clipper bladeset including a stationary blade and a moving blade reciprocating laterally relative to the stationary blade. The attachment comb has a comb base having a rear edge in operational relationship with the stationary blade and an opposite front edge, the base defining a centerline extending between the rear edge and the front edge. A plurality of comb teeth are provided, each having a tooth base associated with the front edge and a tip opposite the tooth base. The teeth are arranged on the comb to have a nonuniform spacing between adjacent teeth relative to the centerline, such that the spacings of the teeth are bilaterally symmetrical about the centerline.

Claims (23)

1. A hair clipper attachment comb for use with a powered hair clipper having a clipper bladeset including a stationary blade and a moving blade reciprocating laterally relative to the stationary blade, said attachment comb comprising:

a comb base having a rear edge in operational relationship with the stationary blade and an opposite front edge, said base defining a centerline extending between said rear edge and said front edge;

a plurality of comb teeth each having a tooth base associated with said front edge and a tip opposite said tooth base;

said teeth being arranged on said comb to have a nonuniform spacing between adjacent teeth relative to said centerline, such that said spacings between said teeth are bilaterally symmetrical about said centerline;

said spacing between said comb teeth includes a first spacing distance for a first pair of said teeth straddling said centerline, a second spacing distance for second pairs of said teeth next adjacent said first pair of teeth; and a third spacing distance for third pairs of said teeth next adjacent said second pairs of said teeth, said first, second and third spacing distances decrease progressively from said centerline;

said front edge of said attachment comb base adjacent comb teeth rear ends defines between adjacent teeth “U”-shape, and a radius of a base of the “U” is reduced correspondingly from said centerline with the decreased tooth spacing progressively from said centerline;

each said comb has an inclined surface extending gradually upwardly from said tooth base adjacent said comb base and towards said comb tooth rear end; and

said rear edges of each said comb define a line in spaced relationship to a cutting line defined by the clipper bladeset, a distance between said line and said cutting line being in the range of 0.0625 to 0.25 inch for enhancing a flow of hair through said attachment comb.

2. The attachment comb of claim 1 , wherein said first spacing distance is greater than said second spacing distance, which is greater than said third spacing distance.

3. The attachment comb of claim 1 , wherein said first, second and third spacing distances are different from each other.

4. The attachment comb of claim 1 , wherein each comb tooth is provided with chamfered edges for reducing clogging of hair near the clipper bladeset and enhancing hair flow through the comb.

5. The attachment comb of claim 4 , wherein a rear edge of each comb tooth rear end is at least one of tapered and multi-faceted.

6. The attachment comb of claim 4 , wherein ridge edges of each said comb tooth are chamfered from a rear edge to a tip.

7. The attachment comb of claim 1 , wherein rear edges of each said comb tooth define a line in spaced parallel relationship to a cutting line defined by the clipper bladeset, a distance between said line and said cutting line being in the range of 0.0625 to 0.25 inch for enhancing a flow of hair through said attachment comb.

8. A hair clipper attachment comb for use with a powered hair clipper having a clipper bladeset including a stationary blade and a moving blade reciprocating laterally relative to the stationary blade, said attachment comb comprising:

a comb base having a rear edge in operational relationship with the stationary blade and an opposite front edge;

a plurality of comb teeth each having a tooth base associated with said front edge and a tip opposite said tooth base;

each comb tooth is provided with chamfered edges for enhancing hair flow through the comb;

a rear edge of each comb tooth rear end adjacent said chamfered edges is tapered and multi-faceted, such that said tooth rear end has a pair of inwardly angled side edges tapered toward a tooth centerline;

a spacing between said comb teeth includes a first spacing distance for a first pair of said teeth straddling said centerline, a second spacing distance for second pairs of said teeth next adjacent said first pair of teeth; and a third spacing distance for third pairs of said teeth next adjacent said second pairs of said teeth, said first, second and third spacing distances decrease progressively from said centerline

said front edge of said attachment comb base adjacent said comb teeth rear ends define a “U”-shape, and a radius of a base of the “U” decreases progressively from said centerline in conjunction with said tooth spacing;

said rear edges of each said comb define a line in spaced parallel relationship to a cutting line defined by the clipper bladeset, a distance between said line and said cutting line being in the range of 0.0625 to 0.25 inch for enhancing a flow of hair through said attachment comb; and

each said comb tooth has an inclined surface extending gradually upwardly from said tooth base adjacent said comb base and towards said comb tooth rear end.
