  • Patent number: 8453333
    Abstract: A blade head assembly for a hand-held hair cutting appliance includes a blade clamping device urging a cutting edge margin of a second blade in sliding engagement with a cutting edge margin of a first blade. The blade clamping device includes a clamping head operable for pivoting generally toward and generally away from the second blade about a pivot axis. The clamping head is resiliently biased generally toward the second cutting blade about the pivot axis into sliding engagement with the second blade. The second blade is slidable relative to the clamping head during reciprocating movement of the second blade relative to the first blade.

  • Publication number: 20120291797
    Abstract: A hair styling apparatus includes a hair-heating device for applying heat to hair. The hair-heating device has a moisture-temperature setting and a dry-temperature setting less than moisture-temperature setting. A moisture sensor detects a moisture-indicating parameter of the hair, and generates a moisture-indicating signal indicative of whether the hair is at or below a predetermined moisture threshold level. A control circuit adjusts the temperature of the hair-heating device from the moisture-temperature setting to the dry-temperature setting in response to the moisture sensor generating a moisture-indicating signal indicative of the hair being at or below the predetermined moisture threshold level. The hair-heating device is active in the dry-temperature setting.

  • Publication number: 20120233865
    Abstract: An adjustable comb assembly, which is attachable to an electric hair cutting appliance of the type including opposing cutting blades defining a cutting edge margin for cutting hair, includes a plurality of teeth for regulating a haircut length resulting from the hair being cut by the cutting edge margin of the electric hair cutting appliance. The teeth are selectively movable relative to the cutting edge of the electric hair cutting appliance to any one of a substantially infinite number of different haircut length positions within a range from a maximum haircut length position, in which the comb assembly facilitates cutting hair to a maximum haircut length, to a minimum haircut length position, in which the comb assembly facilitates cutting hair to a minimum haircut length.

  • Patent number: 8091563
    Abstract: A hair styling apparatus has a heating member and a cloth covering at least a portion of the heating member to define a hair-facing surface onto which hair is placed in contact therewith for heating. The cloth is constructed at least in part of a monofilament of a fluorinated polyethylene. In another embodiment, the cloth is responsive to heating of the heating member to shrink relative to the heating member in at least one of a longitudinal direction and a transverse direction of the cloth. In yet another embodiment, the cloth is unbonded to the heating member and held in tension over the portion of the heating member that defines the hair-facing surface.

  • Patent number: 8079149
    Abstract: A hand-held hair cutting appliance has a housing, a first cutting blade, and a second cutting blade. The first cutting blade is capable of reciprocating movement relative to the housing. A drive assembly is operatively connected to the first cutting blade for drivingly reciprocating the first cutting blade relative to the housing such that the first cutting blade is moveable in a side to side direction relative to the housing and the second cutting blade. A counter weight is adapted for reciprocating movement relative to the housing in response to reciprocating movement of the first cutting blade. The counter weight has at least one of a mass and a location relative to the first cutting blade to thereby at least partially counter-balance the reciprocating movement of the first cutting blade.
