  • Patent number: 9061428
    Abstract: A shaving apparatus has at least one cutting unit (3) having an outer shaving surface (7) for contacting the skin, interrupted by hair entry apertures (8), an internal cutter (5) which is drivable for movement along the hair entry apertures (8) for cutting off hairs projecting through the hair entry apertures (8). A suspension member (6) via which the external cutter is suspended relative to the holder (2) is tiltable relative to the holder (2) about a tilting axis (17) located more closely to a first peripheral portion (18) of the shaving surface (7) than to a second peripheral portion (19) of the shaving surface (7) opposite to said first peripheral portion (18) of said shaving surface (7).

  • Publication number: 20070209206
    Abstract: The invention relates to a shaving head (5) comprising at least two bladeshaped cutting members (7, 7?, 7?) each having a straight cutting edge (9, 9?, 9?) extending parallel to a longitudinal direction (Y) of the shaving head. Each cutting member is supported in a cartridge (11) of the shaving head by means of a supporting member (17) which supports the respective cutting member in a supported area (23) on the respective cutting member. Said supported area extends over a predetermined distance (D) perpendicular to the longitudinal direction. Each supporting member has a first portion (25) in contact with the supported area at a location remote from the cutting edge of the respective cutting member and a second portion (27) in contact with the supported area at a location near the cutting edge of the respective cutting member. The first portion has a basic cross-sectional area, seen perpendicularly to the longitudinal direction, and the second portion has a reduced cross-sectional area.

  • Publication number: 20070151107
    Abstract: A safety razor apparatus having a blade assembly (2) comprising two guiding members (9,10), each having a surface for abutting against the skin, and one or more blades (11,12,13) located between said two guiding members (9,10), wherein the cutting edge (14) of each blade (11,12,13) and said surfaces are positioned substantially in one plane. The apparatus has a grip portion (1) being pivotal relative to said blade assembly (2) about a pivot axis (8), wherein the pivot axis (8) is positioned parallel to said cutting edge (14). A location of said pivot axis (8) is adjustable with respect to said blade assembly (2).

  • Publication number: 20070151106
    Abstract: The invention relates to a device (1) for shaving hairs growing from skin (27). The device comprises a base portion (3) having a grip (5). The device further comprises a shaving head (7) which carries at least one cutting member (9, 11) having at least one cutting edge (13, 15). The device has an actuator (35) for effecting a periodical motion (P) of the cutting member relative to the base portion in order to improve the cutting action of the cutting member. According to the invention, the shaving head (7) is pivotable relative to the base portion (3) about a pivot axis (25), and the periodical motion (P) of the cutting member (9, 11) is a periodical motion relative to the shaving head. As a result, the position and orientation of the shaving head relative to the skin (27) are less dependent on the manner in which the user holds the device (1) in his hand and positions the device relative to the skin.

  • Publication number: 20070151108
    Abstract: A safety razor apparatus having a blade assembly (2) comprising two guiding members (9, 10), each having a surface for abutting against a skin, and one or more blades (11, 12, 13) being located between said two guiding members (9, 10). The cutting edge (14) of each blade (11, 12, 13) and said surfaces are positioned substantially in one plane (20). The apparatus has a grip portion (1) being connected to said blade assembly (2). The position of at least one of the two guiding members (9, 10) is adjustable in a direction perpendicular to said plane (20).

  • Publication number: 20070124939
    Abstract: The invention relates to a method of manufacturing a razor blade (4) from a blank (19), the razor blade (4) having an edge portion (6) with a cutting edge (7) and a further portion (9) bent relative to the further portion (8). The blank (19) is bent and hardened. The bending of the blank (19) includes a local heat treatment after hardening. A razor blade (4) made by this method and a device for carrying out this method are also described.

  • Publication number: 20050252005
    Abstract: The invention relates to a device (1) for shaving hair (93) and to a shaving head (9) used therein. The shaving head (9) has at least one cutting member (17, 19) having a cutting edge (23) and a cutting direction (X), and the device has an actuator (29) for effecting a periodical motion of said cutting member relative to a base portion (3) of the device. According to the invention said periodical motion is effected in an imaginary plane which extends transversely to the cutting edge (23) and which has a first motion portion (89) and a second motion portion (91) following the first motion portion. The first motion portion is mainly directed in the cutting direction (X), and the second motion portion is mainly directed opposite to the cutting direction and is closer to the skin (93) than the first motion portion. Said periodical motion results in a reduced risk of skin irritations and skin injuries and provides a smooth shaving result.
