A hair length mapping or cutting device uses multiple comb elements to capture bunches of hair as it is traversed across a scalp. The comb elements are traversed away from the scalp to individually measure or cut each bunch of hair to length. Hair may be cut to conform to a hair style mapped, for instance, from an earlier measurement of a hair style.

A releasable attachment comb coupled to a cutting head of a hair cutting device providing an adjustable hair cutting length. The attachment comb comprising clamping elements disposed at opposite ends of a support bar a set of comb teeth arrayed along the support bar between the clamping elements. Locating/retaining notches provided on opposing inner faces of the clamping element defining a series of clamping positions to receive and lock a cutting element of the cutting head. The locating notches arranged on the opposed inner faces of the clamping elements defining between them a sloped clamping plane for the cutting element. The notches defining clamping positions at multiple points along the sloped plane. The clamping elements adapted to be displaceable away from one another so as to displace the respective notches of each clamping element away from one another, thereby permitting release and advancement of a received cutting element from one clamping position to another.

A blade set for a hair cutting appliance includes a stationary blade and a cutter blade. The stationary blade has a blade base and a plurality of teeth extending from the blade base in a longitudinal direction. The teeth are arranged in a series alternating with tooth gaps therebetween, where the tooth gaps define hair entry slots. The teeth have a first side arranged to cooperate with the cutter blade to cut hair and a second side arranged as a skin-facing side. The teeth have processing edges at the first side at their longitudinal extension, where the smoothened processing edges have smoothened edge transitions.

A wirelessly charging hair clipper is provided. The hair clipper includes a housing that includes a plurality of blades that are driven by an electric motor to allow the plurality of blades to oscillate from side to side relative to one another to cut hair. The housing supports a receiving assembly that is electromagnetically coupled to a transmitting assembly of a charging platform to form an inductive charging system. The housing of the hair clipper is configured to be placed against the charging platform, wherein the transmitting assembly transmits a current by an electromagnetic field to the receiving assembly to recharge a battery electrically connected to the receiving assembly, thereby wirelessly charging the hair clipper. The wirelessly charging hair clipper is configured to prevent clutter by eliminating electrical wires that are constantly entangled.

The present invention relates to a cutter system for an electric shaver and/or trimmer, including a pair of cooperating cutting elements movably supported relative to each other by a support structure, where one of the cutting elements is sandwiched between the other cutting element and the support structure, where the support structure includes at least one spacer defining a gap in which the sandwiched cutting element is movably received, the spacer and thus said gap having a thickness larger than the thickness of the sandwiched cutting element by an amount smaller than 40 μm.

A cutting unit having a blade carrier carrying a cutting blade, and a guard. The guard includes a blade-facing surface engaging the cutting blade at a cut location, a planar guard contact surface for contacting the user's skin, where the guard contact surface is angled with respect to the blade-facing surface, and a guard extender separate from the guard. The guard extender includes a planar extension contact surface cooperating with the guard contact surface to provide an extended contact zone across the guard and the guard extender for contacting a user's skin. The blade-facing surface and the guard contact surface converge towards a tip of the guard, such that a cutting direction extends along the guard contact surface towards the tip. The extended contact zone may provide for improved stability and reliable orientation of the cutting unit for cutting while limiting material use.
