Patent number: 8555509Abstract: A shaving unit for an electric shaver which comprises an outer cutter and an inner cutter associated to that outer cutter. The cutters are mounted so as to be movable relative to each other and adapted to be set in a relative motion by a drive mechanism. The inner cutter provides a plurality of cutting edges and abuts with its outer face on the inner face of the outer cutter. The outer cutter provides a plurality of teeth equipped with cutting edges. The outer cutter provides two comb elements which are disposed opposite one another and which extend according to the direction of the relative motion. The two comb elements are aligned with respect to one another such that the tips of the teeth of the first comb element are facing the tips of the teeth of the second comb element, the tips of the teeth spaced from one another.Type: GrantFiled: July 29, 2011Date of Patent: October 15, 2013Assignee: Braun GmbHInventors: Thorsten Pohl, Joachim Krauss, Tobias Schwarz, Peter Junk, Reinhold Eichhorn, Andreas Peter, Michael Odemer, Martin Fuellgrabe, Christoph Zegula, Alois Koeppl, Stefan Fuerst

Publication number: 20110016727Abstract: The invention relates to a cutting device (1) for cutting hair, having at least two blades (2, 3) which move back and forth relative to each other. The blades (2, 3) are provided with teeth (8, 9) which extend transversally to the direction of movement (P), and tooth gaps (25, 26) arranged therein. The teeth (8, 9) have contact surfaces (4, 5) on their facing sections which are in gliding contact with each other and which form cutting edges (34, 35) on their sides bounding the tooth gaps (25, 26) such that the back and forth movement (P) of the blades causes the tooth gaps (25, 26), cooperating with each other, to form constantly changing cutting gaps (32) in which hair becomes clamped and is finally cut. According to the invention, the free ends of teeth (9) of one blade (3) project over sections (15) of free ends of teeth (9) of other blades (2), and projections (17) extend from the projecting sections (15) of the teeth (9) on the contact surfaces (5) side.Type: ApplicationFiled: May 2, 2008Publication date: January 27, 2011Applicant: The Procter & Gamble CompanyInventors: Stefan Fuerst, Oliver Von Sartori-Montecroce
