Patent number: 11745369Abstract: 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.Type: GrantFiled: December 20, 2021Date of Patent: September 5, 2023Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Marcus Franciscus Eijkelkamp, Arjen De Boer, Martijn Frans Johan Nab, Roel Alexander Rethmeier, Willem Maat

Patent number: 11364647Abstract: 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.Type: GrantFiled: April 8, 2019Date of Patent: June 21, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Marcus Franciscus Eijkelkamp, Arjen De Boer, Martijn Frans Johan Nab, Willem Maat, Roel Alexander Rethmeier

Publication number: 20220152852Abstract: 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.Type: ApplicationFiled: February 1, 2022Publication date: May 19, 2022Inventors: Arjen DE BOER, Roel Alexander RETHMEIER, Willem MAAT, Martijn Frans Johan NAB, Marcus Franciscus EIJKELKAMP
