Abstract
A hair cutting kit includes a handle, a first trimmer head for releasable attachment to the handle, a second trimmer head for releasable attachment to the handle, and a comb implement including at least one row of comb teeth. A mechanical interface is provided for releasable attachment of the comb implement to the first trimmer head and for releasable attachment of the comb implement to the second trimmer head.
Claims19
A hair cutting kit, comprising:
- a handle;
- a first trimmer head configured for releasable attachment to the handle, the first trimmer head comprising at least one first stationary blade comprising at least one row of first teeth comprising consecutive first teeth, wherein the at least one row of first teeth extends in a first direction perpendicular to central longitudinal axes of the first teeth, and the central longitudinal axes of pairs of the consecutive first teeth are spaced from each other along the first direction by a first pitch;
- a second trimmer head configured for releasable attachment to the handle, the second trimmer head comprising at least one second stationary blade comprising at least one row of second teeth comprising consecutive second teeth, wherein the at least one row of second teeth extends in the first direction, central longitudinal axes of the second teeth are perpendicular to the first direction, and the central longitudinal axes of pairs of the consecutive second teeth are spaced from each other along the first direction by a second pitch;
- a comb implement comprising a row of comb teeth comprising consecutive comb teeth and a mechanical interface operative for releasable attachment of the comb implement to the first trimmer head and for releasable attachment of the comb implement to the second trimmer head;
- wherein the comb implement is configured such that when the comb implement is attached to the first trimmer head or the second trimmer head, the row of comb teeth extends in the first direction, pairs of the consecutive comb teeth of the row of comb teeth are separated from each other along the first direction by comb tooth gaps, mid-planes of the comb teeth are perpendicular to the first direction, and the mid-planes of the pairs of the consecutive comb teeth are spaced from each other along the first direction by a third pitch;
- wherein the third pitch is equal to the first pitch multiplied by a first numerical value and the third pitch is equal to the second pitch multiplied by a second numerical value different from the first numerical value;
- wherein the first numerical value and the second numerical value are each greater than 1.

A hair cutting kit, comprising:
- a handle;
- a trimmer head attached or releasably attachable to the handle, the trimmer head comprising at least one stationary blade comprising at least one row of blade teeth comprising consecutive blade teeth, wherein the at least one row of blade teeth extends along a first direction perpendicular to central longitudinal axes of the blade teeth, and pairs of the consecutive blade teeth are separated from each other along the first direction by gaps, wherein each gap defines a first pitch;
- and
- a comb implement comprising at least one row of comb teeth comprising consecutive comb teeth, the comb implement being configured for releasable attachment to the trimmer head or the handle and being configured such that, when the comb implement is attached, the at least one row of comb teeth extends in the first direction, pairs of the consecutive comb teeth are separated by comb tooth gaps, wherein each gap defines a second pitch, and some, a majority, or all of the comb teeth overlap, when viewed in a viewing direction perpendicular to the first direction, the gaps between the pairs of the consecutive blade teeth;
- wherein the second pitch is equal to the first pitch multiplied by a first numerical value;
- wherein the first numerical value is an integer greater than 1 and less than or equal to 5.
