Abstract
A hair clipper or cutter is provided with an adjustment slider that adjusts the gap between an inner and outer blade. A yoke is attached to the inner blade. The adjustment slider may be configured with preset gap lengths and may be adjustable before, after, or during a hair cutting operation. A T-guide couples the adjustment slider to the inner blade to slidably move the inner blade relative to the outer blade. The yoke, inner blade, outer blade and/or T-guide may be magnetized to create an attractive or repulsive force between the inner blade and the outer blade.
Claims20
A magnetic blade assembly, comprising:
- a first blade having first teeth extending along a first blade edge;
- a second blade having second teeth extending along a second blade edge, the second blade supported relative to the first blade such that the second teeth are moveable relative to the first blade to cut hair;
- and
- a blade guide positioned between the first blade and the second blade, the blade guide maintains a position of the first blade edge relative to the second blade edge;
- and
- a magnetic assembly comprising:
- a holder coupled to the first blade;
- a first magnet coupled to the holder;
- a second magnet coupled to a surface of the second blade, the surface facing away from the first blade;
- wherein the magnetic assembly generates a tensioning force between the first blade and the second blade.
A magnetic blade assembly, comprising:
- a first blade having first teeth extending along a first blade edge;
- a second blade having second teeth extending along a second blade edge parallel to the first blade edge, the second blade comprising:
- a first side facing the first blade;
- and
- a second side opposing the first side, the second side connected to and extending from the second blade edge;
- a blade guide assembly comprising:
- a guide configured to engage a portion of the second blade to maintain a position of the first blade edge relative to the second blade edge;
- and
- a magnetic assembly comprising:
- a holder comprising one or more arms;
- a first permanent magnet fastened to the one or more arms of the holder;
- a second permanent magnet coupled to the second side of the second blade;
- wherein the magnetic assembly generates a tensioning force between the first blade and the second blade.
A magnetic blade assembly, comprising:
- an outer blade having first teeth extending along an outer blade edge;
- an inner blade having second teeth extending along an inner blade edge, the inner blade supported relative to the outer blade such that the second teeth are moveable relative to the outer blade to cut hair;
- and
- a blade guide configured to engage a portion of the inner blade to maintain a position of the outer blade edge relative to the inner blade edge;
- and
- a magnetic assembly comprising:
- a holder coupled to the outer blade and extending over the inner blade;
- a first magnet positioned between the holder and the inner blade;
- a second magnet spaced from the first magnet, the second magnet positioned between the holder and the inner blade
- wherein the magnetic assembly generates a tensioning force between the outer blade and the inner blade and wherein the tensioning force maintains a relative position of the inner blade edge to the outer blade edge.
