  • Patent number: 11745369
    Abstract: 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.

  • Patent number: 11364647
    Abstract: A hair cutting device having a cutting unit, the cutting unit including a blade carrier carrying a cutting blade that has cutting teeth; a guard blade that has guard teeth. The blade is movable along the blade carrier relative to the cutting blade within a guard length range between a first guard position corresponding to a shortest hair cutting length of the cutting unit and a second guard position corresponding to the longest hair cutting length of the cutting unit. The blade carrier includes a stop configured to prevent movement of the guard blade past the first guard position and outside of the guard length range, thereby preventing the cutting length from being below the shortest cutting length.

  • Publication number: 20220152852
    Abstract: 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.

  • Patent number: 11267147
    Abstract: A blade set assembly for a hair cutting appliance includes a stationary blade and a movable blade. The movable and stationary blades are arranged one on top the other and movable relative to each other. A guide unit is formed between the movable blade and the stationary blade, where the blades engage each other. The guide unit includes longitudinally spaced, laterally extending guideways, each defined between a stationary blade guide surface and a movable blade guide surface that overlap each other. Rolling elements are arranged at the guideways between the guide surfaces. The guide surfaces have a height extension greater than a radius of the rolling elements such that the guide surfaces overlap in a vertical direction. The guide surfaces provide for coupling in a longitudinal direction between the blades such that the guide unit provides for a set longitudinal distance for any force applied in the longitudinal direction.
