Abstract

An adjustable comb for use on a clipper having one of a first lower blade of first size or a second lower blade of second size. One of these lower blades is an active blade when attached to the clipper. The adjustable comb includes an adjustment mechanism for adjusting the position of a retaining tab that engages a rear edge of the active blade. The adjustment mechanism is shifted in a first direction to position the retaining tab for the first lower blade, and is shifted in a second direction to position the retaining tab for the second lower blade.

First claim

What is claimed is:

1. A hair clipper comprising:
a prime mover;
a removable lower blade having a cutting edge and a rear edge opposite and generally parallel to the cutting edge, the removable lower blade coupled to a portion of the hair clipper;
an upper blade being reciprocated adjacent the removable lower blade under the influence of the prime mover to create a shearing action between the upper blade and the removable lower blade for cutting hair;
a comb attachment removably attached to a first portion of the removable lower blade and defining a length of cut for the clipper;
an attachment mechanism that removably attaches the comb attachment to a second portion of the removable lower blade;
a slide body movably mounted to the comb attachment;
a retaining tab mounted to the slide body and positioned adjacent the rear edge of the removable lower blade to resist sliding movement of the comb attachment in a forward direction with respect to the removable lower blade; and
an adjustment mechanism interconnected between the comb attachment and the slide body, the adjustment mechanism being shiftable to move the retaining tab forward into a first position, and being shiftable to move the retaining tab rearward into a second position.

2. The clipper of claim 1 , wherein the comb attachment includes a plurality of tines defining a hooked portion of the comb attachment; wherein the cutting edge of the removable lower blade is adjacent the hooked portion of the comb attachment; and wherein engagement of the hooked portion against the cutting edge of the removable lower blade resists sliding movement of the comb attachment in a rearward direction with respect to the removable lower blade.

3. The clipper of claim 1 , wherein the comb attachment includes a pair of spaced rails; and wherein the slide body is slidable on the pair of spaced rails to move the retaining tab between the first position and the second position.

4. The clipper of claim 1 , wherein the adjustment mechanism is shifted in a first direction to move the retaining tab forward into the first position, and shifted in a second direction opposite the first direction to move the retaining tab rearward into the second position, the first and second directions being perpendicular to the forward direction.

5. The clipper of claim 1 , wherein the adjustment mechanism includes an adjustment plate that is supported on the comb attachment for sliding movement; wherein the adjustment plate includes a diagonal slide groove that is oblique to the forward direction; wherein the slide body includes at least one depending finger that is received in the diagonal slide groove; and wherein movement of the adjustment plate causes the at least one depending finger to move within the diagonal slide groove to urge the slide body in the forward and rearward directions.

6. The clipper of claim 1 , further comprising a detent mechanism for resiliently holding the slide body in the first and second positions with respective first and second detent forces.

7. The clipper of claim 6 , wherein the adjustment mechanism includes an adjustment plate that is supported on the comb attachment for sliding movement; wherein the detent mechanism includes at least one detent finger on the comb attachment and a detent pin on the adjustment plate; wherein the at least one detent finger defines a detent slot including first and second wide sections; wherein the detent pin is received within the detent slot and movable into the first wide section and the second wide section to respectively resist movement of the slide body from the first position and second position; and wherein an adjustment force on the adjustment plate in excess of the first detent force and second detent force resiliently deflects at least one of the at least one detent finger to permit the detent pin to move out of the respective first and second wide sections without breaking at least one of the at least one detent finger.

8. The clipper of claim 1 , wherein the comb attachment includes first and second slide rails; and wherein the slide body engages the first and second slide rails on opposite sides of the slide body, such that the slide body slides along the first and second slide rails between the first and second positions.

9. The clipper of claim 1 , wherein the attachment mechanism includes a magnet carried by the comb attachment for magnetically attaching the comb attachment to the removable lower blade.

10. The clipper of claim 9 , wherein the magnet is mounted to the comb attachment by the slide body.

11. A hair clipper comprising:
a prime mover;
a removable lower blade having a cutting edge and a rear edge opposite and generally parallel to the cutting edge, the removable lower blade coupled to a portion of the hair clipper;
an upper blade being reciprocated adjacent the removable lower blade under the influence of the prime mover to create a shearing action between the upper blade and the removable lower blade for cutting hair;
a comb attachment removably attached to a first portion of the removable lower blade and defining a length of cut for the clipper;
a slide module including:
a slide body movably mounted to the comb attachment,
a retaining tab mounted to the slide body and positioned adjacent the rear edge of the removable lower blade to resist sliding movement of the comb attachment in a forward direction with respect to the removable lower blade, and
an attachment mechanism that removably attaches the comb attachment to a second portion of the removable lower blade; and

an adjustment mechanism interconnected between the comb attachment and the slide body, the adjustment mechanism being shiftable to move the retaining tab forward into a first position, and being shiftable to move the retaining tab rearward into a second position.

12. The clipper of claim 11 , wherein the comb attachment includes a plurality of tines defining a hooked portion of the comb attachment; wherein the cutting edge of the removable lower blade is adjacent the hooked portion of the comb attachment; and wherein engagement of the hooked portion against the cutting edge of the removable lower blade resists sliding movement of the comb attachment in a rearward direction with respect to the removable lower blade.

13. The clipper of claim 11 , wherein the comb attachment includes a pair of spaced rails; and wherein the slide body is slidable on the pair of spaced rails to move the retaining tab between the first position and the second position.

14. The clipper of claim 11 , wherein the adjustment mechanism is shifted in a first direction to move the retaining tab forward into the first position, and shifted in a second direction opposite the first direction to move the retaining tab rearward into the second position, the first and second directions being perpendicular to the forward direction.

15. The clipper of claim 11 , wherein the adjustment mechanism includes an adjustment plate that is supported on the comb attachment for sliding movement; wherein the adjustment plate includes a diagonal slide groove that is oblique to the forward direction; wherein the slide body includes at least one depending finger that is received in the diagonal slide groove; and wherein movement of the adjustment plate causes the at least one depending finger to move within the diagonal slide groove to urge the slide body in the forward and rearward directions.

16. The clipper of claim 11 , further comprising a detent mechanism for resiliently holding the slide body in the first and second positions with respective first and second detent
