Claim of US Patent No. 10,034,455

1. An implement for grooming hair of an animal, comprising:a handle having a length defining a longitudinal axis of the implement;
a comb support having first and second opposed ends, the first end being coupled to the handle;
an array of substantially rigid tines mounted to the comb support, each tine having (i) a base, by which it is mounted to the comb support, (ii) a tip, (iii) a length that protrudes from the base to the tip, and (iv) a width at where the tine protrudes from its base, wherein the array is configured so that a selected tine has a length that is more than three times greater than the width of the selected tine, the array having a plurality of generally parallel combs, wherein any selected comb in the array has a set of regularly spaced generally parallel tines of similar length, and each comb has a length disposed transversely with respect to the longitudinal axis, and the comb support is configured in relation to the combs so that substantially all of the length of each tine is exposed for use in grooming;
wherein the spacing between adjacent tines of a selected comb in the array monotonically decreases as a function of distance of the selected comb from the first end, in a manner wherein there are at least three distinct spacings between centers of adjacent tines in the combs of the array;
so that, as the comb support is drawn in a direction of motion along the longitudinal axis to effectuate the grooming of the hair of the animal, in a manner wherein the first end reaches a selected location on the animal and thereafter the second end reaches the selected location, hair at the selected location experiences a progression in at least three stages from coarsely to more finely spaced tines;
wherein the tines of the array are configured to penetrate and groom the hair of the animal,
wherein the length of the tines of the selected comb monotonically decreases as a function of distance of the selected comb from the first end;
so that, as the comb support is drawn in the direction of motion along the longitudinal axis to effectuate the grooming of the hair of the animal, hair at the selected location experiences a progression from longer to shorter tines.
