Abstract
A hair cutter with an improved blade assembly is described. The blade assembly includes a first blade, a second blade, a yoke coupled to the second blade, a blade guide between the first and second blade, a retainer, and a biasing mechanism. The biasing mechanism includes a base and at least one arm configured to interface with and move with the second blade. The retainer is positioned behind the second blade and engages the biasing mechanism. The retainer is further configured to receive a housing connector, allowing for coupling to a handle of the hair cutter.
Claims20
A blade assembly, comprising:
- a first blade having first teeth extending along a front portion of the first blade;
- a second blade having second teeth extending along an edge parallel to the front portion of the first blade, wherein the second blade is supported relative to the first blade;
- a plurality of biasing members, each biasing member comprising:
- a plurality of free ends;
- a plurality of angled biasing arms extending from the plurality of free ends;
- a plurality of fixed ends extending from the plurality of angled biasing arms;
- a plurality of securing arms extending from each of the fixed ends;
- and
- a base extending between the plurality of securing arms;
- and
- a retainer coupled to the first blade and engaged by the plurality of biasing members;
- wherein the base of each of the plurality of biasing members are stacked and aligned with each other such that one base is positioned between the other base and the first blade.
