Patent number: 11979074Abstract: The invention relates to a motor suspension for rigid and watertight mounting of a motor to a housing of an electric device, an electric device comprising such a motor suspension and a hair cutting device comprising an electric device with such a motor suspension. The motor suspension comprises a motor fixation element, a sealing suspension element and a motor axis seal. The motor fixation element is configured to provide a rigid connection of a motor to a housing in one direction, while it provides some flexibility in another direction for not deforming the housing. The sealing suspension element is configured for providing a fluid-tight connection to the housing, and the motor axis seal is configured for providing a fluid tight connection of the sealing suspension element to a rotational axis of the motor.Type: GrantFiled: July 30, 2020Date of Patent: May 7, 2024Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Marcus Franciscus Eijkelkamp, René Van Den Berg, Michiel Allan Aurelius Schallig, Marcel Hilco Zijlstra, Harold Wolf, Rob Roetert, Hendrik Klaas Haagsma

Patent number: 11027441Abstract: A hair cutting device includes a hair cutting device body and an interchangeable comb unit for defining a hair length after cutting. The hair cutting device body further includes a comb interface for releasable attachment of the comb unit to the hair cutting device body, and a hair length indicator operatively coupled to the comb interface for indicating the hair length to a user. The interchangeable comb unit includes a comb identification member for identifying a hair length associated with the comb unit, and the comb interface includes a comb recognition arrangement being electrically coupled to the hair length indicator. The comb recognition arrangement is configured to sense the comb identification member when the comb unit is connected to the hair cutting device body, and to provide an electronic signal indicative of the hair length associated with the comb unit to the hair length indicator.Type: GrantFiled: July 18, 2016Date of Patent: June 8, 2021Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Dirk Hendrik Wevers, Hendrik Jan Mark Van Der Worp, Auke Tuinstra, Johan Willem Berenschot, Hedzer Michiel Adriaan Van Der Kamp, Willem Joosten, Marcel Hilco Zijlstra, Ishay Halmut, Jeroen Christian Nijdam

Patent number: 10029377Abstract: The present application relates to a hair trimming device (10). The hair trimming device has a body (11) with a cutting blade assembly (20). A cutting guide (40) is provided on the body and the position of the cutting guide is adjustable relative to the cutting blade assembly to provide a cutting distance from a user's skin to enable hair to be cut to a desired length. A locking unit (60) is also provided to lock the cutting guide at a desired position relative to the cutting blade assembly. The locking unit comprises a first locking element (64), a second locking element (65) and at least one receiving recess (83). The first and second locking elements are alternately locatable in the or one of the receiving recesses when the position of the cutting guide is adjusted relative to the cutting blade assembly to lock the cutting guide at different positions.Type: GrantFiled: September 18, 2013Date of Patent: July 24, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Marcel Hilco Zijlstra, Reinier Alexander Tijssen, Hendrik Jan Mark Van Der Worp, Hendrik Klaas Haagsma, Vidyadhar Hanumanthappa, Dimitri Peter Heuvel, Bastiaan Hendrik De Raat
