Comb for a hair clipper
This application concerns a hair-thinning comb ( 200 ) comprising pairs of comb teeth. Each pair comprises a primary comb tooth ( 216 ) and an adjacent secondary comb tooth ( 217 ). A distal primary tip ( 218 ) of the primary comb tooth ( 216 ) extends longitudinally beyond a distal secondary tip ( 219 ) of the secondary comb tooth ( 217 ). A blocking channel ( 226 ) between roots of the primary and secondary comb teeth ( 216, 217 ) prevent hairs received therein from reaching a cutting element ( 106 ) of a hair clipper ( 100 ). There is also a cutting gap ( 225 ) separating adjacent pairs of comb teeth to permit hair to pass to a cutting element ( 106 ) clipper ( 100 ). The distal primary tips ( 218 ) separate hair in a first separation stage, and the distal secondary tips ( 219 ) separate hair between the blocking channel ( 226 ) and the cutting gap ( 225 ) in a second separation stage.
1. A hair-thinning comb comprising:
a support body for attachment to a hair clipper;
a plurality of pairs of comb teeth in side-by-side relationship, wherein each pair of comb teeth comprises:
a primary comb tooth having a longitudinal extent from a root proximal the support body to a distal primary tip;
a secondary comb tooth adjacent to the primary comb tooth, and having a longitudinal extent from a root proximal the support body to a distal secondary tip;
wherein the distal primary tip extends longitudinally beyond the distal secondary tip;
wherein there is a blocking portion between the roots of the primary and secondary comb teeth configured to prevent any hairs received in a blocking channel defined between the primary and secondary comb teeth from reaching a cutting element of the hair clipper; and
wherein adjacent pairs of comb teeth are separated by a cutting gap to permit hair to pass through the cutting gap to a cutting element of a hair clipper;
whereby in use the distal primary tips separate hair in a first separation stage, and the distal secondary tips separate hair received between the primary comb teeth between the blocking channel and the cutting gap in a second separation stage.
2. The hair-thinning comb as claimed in claim 1 , wherein the longitudinal extent of the primary comb tooth is greater than the longitudinal extent of the secondary comb tooth.
3. The hair-thinning comb as claimed in claim 1 , wherein the blocking portion connects the roots of the primary comb tooth and the secondary comb tooth to define the blocking channel.
4. The hair-thinning comb as claimed in claim 1 , wherein the blocking portion comprises a hair-facing edge that is parallel with a lateral direction along which the pairs of comb teeth are spaced apart.
5. The hair-thinning comb as claimed in claim 4 , wherein the primary comb tooth, the secondary comb tooth and the hair-facing edge define an asymmetric U-shaped profile in cross-section.
6. The hair-thinning comb as claimed in claim 1 , wherein the primary comb tooth provides, at least in part, a predetermined fixed spacing between a skin of a user and the cutting element in order to define a hair cutting length.
7. The hair-thinning comb as claimed in claim 1 , wherein a pitch between the distal secondary tip and an adjacent primary comb tooth in a direction parallel with a lateral direction along which the pairs of comb teeth are spaced apart is in the range of 1-3 mm.
8. A hair clipper apparatus comprising:
a hair clipper having a housing and a cutting element; and
a hair-thinning comb as claimed in claim 1 .
