Abstract

A hair clipper variable comb attachment, for use with a hair clipper having a fixed upper blade and a movable lower blade, including a blade mount, a main part, a comb carrier, and a pair of adjustment pegs. The comb carrier has a front and a plurality of longitudinally extending tines that increase in height as they extend rearwardly. The blade mount secures to the fixed upper blade of the clipper. The comb carrier is slidably attached onto the main part so that as the adjustment pegs are rotated the comb carrier can move forwardly with respect to the blade to increase cutting height of the clipper and can move rearwardly to decrease cutting height. Adjustment of the comb carrier position and thus the cutting height can be made without removing the comb attachment from the hair clipper.

Dependent claims

A variable comb device, for attachment to a hair clipper having a clipper blade assembly having a front, a rear, a fixed upper blade, and a movable lower blade, the fixed upper blade has a main plate and a beveled forward portion that contains a plurality of teeth and a pair of forward side parts that are beveled like the teeth but are wider and not configured for cutting, comprising:

a main part having a track with a plurality of protrusions that are spaced apart and parallel to each other, the main part also having a pair of peg mounting assemblies that each include a peg channel, and a square central tube having side openings;
a comb carrier having a front, a rear, a pair of sides, a lower surface, a pair of racks extending longitudinally on the lower surface near the sides, and a plurality of longitudinally extending tines that come to a point at the front and are taller as they extend rearwardly on the comb carrier, the tines mesh with the protrusions on the track which guide the movement of the tines as the comb carrier is adjusted longitudinally with respect to the main part;
a blade mount adapted for attaching to the clipper blade assembly, the main part mounted on top of the blade mount;
and
a pair of adjustment pegs, each having a main shaft, a pinion meshed with one of the racks, a thumb wheel, and a square end, the square end of each adjustment peg extends through one of the peg channels and into one of the side openings of the square central tube, the main shaft is adapted to rotate with respect to the square end so that when the thumb wheel is rotated the pinion rotates and causes the rack to move one of forwardly and rearwardly, adjusting the relative position of the comb carrier and the main part.

A variable comb device, for attachment to a hair clipper and modifying the length of hair about to be cut by said hair clipper, the hair clipper having a clipper blade assembly having a front, a rear, a fixed upper blade, and a movable lower blade, the fixed upper blade has a main plate and a beveled forward portion that contains a plurality of teeth and a pair of forward side parts that are beveled like the teeth but are wider and not configured for cutting, comprising:

a main part having a track with a plurality of protrusions that are spaced apart and parallel to each other;
a comb carrier having a front, a rear, a pair of sides, a lower surface, and a plurality of longitudinally extending tines that come to a point at the front and are taller as they extend rearwardly on the comb carrier, the tines mesh with the protrusions on the track which guide the movement of the tines as the comb carrier is adjusted longitudinally with respect to the main part;
a blade mount adapted for attaching to the clipper blade assembly, the main part mounted on top of the blade mount, the blade mount having a pair of side portions that each have an opposed front pocket, a bridge that connects the side portions, and a blade clip, the opposed front pockets are adapted to fit over the forward side parts of the upper blade, and the blade clip is adapted to selectively engage a rear of the upper blade to lock the comb device onto the clipper blade assembly;
and
an adjustment mechanism, for engaging the comb carrier and providing longitudinal movement of the tines with respect to the protrusions and thereby adapted to adjust the height of the tines at the front of the clipper blade assembly so that the comb carrier can be moved forwardly to increase the height of the tines at the front of the clipper to increase the length of hair about to be cut by the clipper blade assembly and rearwardly to decrease the height of the tines at the front of the clipper blade assembly to decrease the length of the hair about to be cut.
