Abstract
A comb attachment for use on a hair clipper includes tines that have rounded free ends positioned rearward of the cutting edge of a lower blade and forward of the cutting edge of the upper blade. Because of a radius of curvature of the rounded free ends, the free ends do not cross the cutting edge of the upper blade during attachment and removal of the comb attachment.
Claims7
A comb assembly for a hair clipper having a lower blade and an upper blade reciprocating with respect to the lower blade, the lower blade having a lower cutting edge and the upper blade having an upper cutting edge, the upper cutting edge being parallel to and rearward of the lower cutting edge, the comb assembly comprising:
- a comb attachment comprising a body and a plurality of tines extending forward from the body;
- and
- an attachment mechanism for attaching the comb attachment to the lower blade;
- wherein each tine includes an extension portion extending along a bottom side of the lower blade;
- wherein each tine includes a hook portion curving from the extension portion across the lower cutting edge;
- wherein each hook portion includes a rounded free end adjacent a top surface of the lower blade rearward of the lower cutting edge and forward of the upper cutting edge, the rounded free end describing a radius of curvature;
- wherein the comb attachment is pivoted about the lower cutting edge during installation and removal of the comb attachment from the lower blade;
- and
- wherein the radius of curvature of the rounded free end of each hook portion is sized to avoid the free end from crossing the upper cutting edge as the comb attachment is pivoted on the lower cutting edge during installation and removal of the comb attachment.
A hair clipper comprising:
- a prime mover;
- a lower blade having a lower cutting edge;
- an upper blade reciprocating with respect to the lower blade under the influence of the motor, the upper blade having an upper cutting edge that is parallel to and rearward of the lower cutting edge;
- a comb attachment comprising a body and a plurality of tines extending forward from the body;
- and
- an attachment mechanism for attaching the comb attachment to the lower blade;
- wherein each tine includes an extension portion extending along a bottom side of the lower blade;
- wherein each tine includes a hook portion curving from the extension portion across the lower cutting edge;
- wherein each hook portion includes a rounded free end adjacent a top surface of the lower blade rearward of the lower cutting edge and forward of the upper cutting edge, the rounded free end describing a radius of curvature;
- wherein the comb attachment is pivoted about the lower cutting edge during installation and removal of the comb attachment from the lower blade;
- and
- wherein the radius of curvature of the rounded free end of each hook portion is sized to avoid the free end from crossing the upper cutting edge as the comb attachment is pivoted on the lower cutting edge during installation and removal of the comb attachment.
