Patent number: 6684508Abstract: A shaving head comprises a cutting member a hair manipulator. The cutting member has a cutting edge which extends in a direction perpendicular to a shaving direction of the shaving head. The hair manipulator is arranged in front of the cutting edge, seen in the shaving direction, and can be driven in a direction parallel to the cutting edge. Hairs trapped by the hair manipulator are moved along the cutting edge while being cut, so that the cutting forces in the shaving direction are reduced. The cutting member can also be driven in a direction parallel to the cutting edge such that, seen in this direction, the cutting member and the hair manipulator move in opposite directions for a longer period of time than in equal directions. In this manner the cutting member has a stretching effect on the skin present immediately in front of the cutting edge, and said stretching effect of the cutting member intensifies a similar stretching effect of the hair manipulator.Type: GrantFiled: December 20, 2000Date of Patent: February 3, 2004Assignee: Koninklijke Philips Electronics N.V.Inventors: Rudolf Heinrich Brzesowsky, Andreas Johannes Garenfeld, Lucien Ferdinand Anna Douven, Jasper Zuidervaart

Patent number: 6655030Abstract: The invention relates to a shaving head (1) having at least two cutting members, the cutting edge (7)of at least one of the cutting members (5) being situated at a side, remote from the other cutting member (9), of an imaginary center plane (41) of the carrier (31) of the relevant cutting member, and having a tip angle (&agr;1)enclosed by a main side face (37) and a facet surface (43) of the carrier (31). In this manner, the cutting edge of the relevant cutting member has a tip angle (&agr;1) which is asymmetrical relative to the center plane of the carrier. As a result, a space (57), which is present between the carriers (31, 33) of the two cutting members, is divergent, viewed from the skin contact surface (29), and the risk of said space becoming clogged by cut hairs and shaving foam is considerably reduced.Type: GrantFiled: December 18, 2001Date of Patent: December 2, 2003Assignee: Koninklijke Philips Electronics N.V.Inventor: Jasper Zuidervaart

Patent number: 6574866Abstract: A hair removing apparatus (1) comprising two co-operating hair processing members (17, 19), formed by plate-shaped carriers and movable relatively to each other in a direction of movement (X). The two carriers are positioned with respect to each other, viewed in a Z direction substantially perpendicular to the carriers, by a plurality of positioning members (29), which are spaced apart in the direction of movement. At least one of the two carriers has a comparatively low bending stiffness. As a result, a comparatively small and uniform gap is present between the two carriers, and the friction force acting on the carriers in a direction parallel to the direction of movement is also comparatively small. In one embodiment the positioning members (29) each have an S-shaped or C-shaped tongue (31), which is provided on a third carrier (35), the first and second carriers (21, 27) being enclosed between the third carrier and contact elements (41) of the tongues.Type: GrantFiled: June 21, 2001Date of Patent: June 10, 2003Assignee: Koninklijke Philips Electronics N.V.Inventors: Johan Pragt, Robert Alexander Santhagens Van Eibergen, Jan Spoelstra, Fokke Roelof Voorhorst, Jasper Zuidervaart, Martijn Adriaan De Keijzer, Arjan Sander Vonk, Foppe Kramer
