  • Publication number: 20230363522
    Abstract: A personal hygiene device has a handle and a treatment head pivotably connected with the handle. Applying a treatment force against the treatment head causes a pivoting of the treatment head relative to the handle. A sensor, such as, e.g., a Hall sensor, fixedly secured with respect to one of the handle and the treatment head, measures a measurement variable. A sensor cooperation unit defines or influences the measurement variable in dependence on the relative position of the sensor and the sensor cooperation unit, such e.g., as a sensor permanent magnet, fixedly secured relative to one of the handle and the treatment head. A spring unit defines a rest position of the treatment head when no treatment force is applied. The spring unit has a first spring constant in the treatment direction and a second spring constant in a lateral direction, the second spring constant being at least about two times higher than the first spring constant.

  • Patent number: 9533422
    Abstract: A hair removal apparatus is described having a trimmer (4), whereby the trimmer (4) has at least two cutting parts (7, 8) each having rows of teeth drivable individually relative to one another, and having at least one wet shaver unit (21), which has at least one sharp-edged razor blade (22). The wet shaver unit (21) is arranged on a carrying element (19) that is guided movably on the housing (1). The carrying element is adjustable by the user in at least two different positions through a corresponding switching movement. The first position is a storage position of the wet shaver unit and the second position allows simultaneous removal of hair by the trimmer (4) which is leading in the direction of use (P) and the trailing wet shaver unit (21).

  • Patent number: 9302401
    Abstract: The invention is concerned with a trimmer comb (1) that comprises a base sheet (10) that has a toothed front side, the toothed front side comprising a side-by-side arrangement of guard teeth (11) and narrow teeth (12), wherein the tips (15, 11d, 11d?) of the guard teeth (11) are wider in the longitudinal extension direction (y) of the trimmer comb than the tips (15?) of the narrow teeth (12) and the geometry of the narrow teeth (12) is reduced when compared to the geometry of the guard teeth (11). These two different trimmer comb teeth geometries serve to press down skin and to avoid injuries by hooking of trimmer comb teeth into skin pores or channels, while a high cutting efficiency is ensured because of the reduced geometry of the narrow teeth ultimately allowing a reduced average spacing distance between the trimmer teeth for a given width of the guard teeth tips. The invention is also concerned with a hair trimmer comprising such a trimmer comb and a hair removal device comprising such a hair trimmer.

  • Patent number: 8732964
    Abstract: The invention relates to a hair removal device such as for example an electric shaver or a wet shaver, comprising a main device element (10, 20) which accounts for the major portion of the overall weight, and a separate element (30, 40) which can be coupled therewith and which comprises for example a wet-shave blade cartridge (40). The separate element (30, 40) is connected to the main device element (10, 20) via a coupling (23, 33). Said coupling (23, 33) is designed to open under the effect of forces that exceed a minimum force. When the hair removal device (100) is dropped, the separate element (30, 40) is not damaged despite the comparatively greater weight of the hair removal device.

  • Publication number: 20130239413
    Abstract: Disclosed herein is a hair removal apparatus (100) having a base body (10) and a slide (20), which is mounted thereon to be movable (displaceably). At least one wet shaver unit (40) comprising a razor blade, such as a blade cartridge for wet shaving, is mounted on the slide. Due to the mobility of the slide (20), this wet shaver unit (40) is protected from damage in the event of impact of the hair removal apparatus, e.g., in a fall to the floor. Certain target positions of the slide (20) can be secured with a slip clutch, such that they become unlocked on exceeding a minimum force that is acting and thereby release a movement of the slide.

  • Publication number: 20110016729
    Abstract: The invention is concerned with a trimmer comb (1) that comprises a base sheet (10) that has a toothed front side, the toothed front side comprising a side-by-side arrangement of guard teeth (11) and narrow teeth (12). The length (E2) of the narrow teeth (12) measured in axial direction of the trimmer comb teeth (x) is smaller than the length (E1) of the guard teeth (11) and further the guard teeth (11) have widened tips (15, 11d, 11d?). These two different trimmer comb teeth geometries serve to press down skin and to avoid injuries by hooking of trimmer comb teeth into skin pores or hair channels, while a high cutting efficiency is ensured because the smaller narrow teeth allow for a reduced average spacing distance between the trimmer teeth. The invention is also concerned with a hair trimmer comprising such a trimmer comb and a hair removal device comprising such a hair trimmer.

  • Publication number: 20100299937
    Abstract: The invention concerns a trimmer comb (1) that comprises a base sheet (10) with a toothed front side that has at least a guard tooth (11) that has a thickened tip (11d) that is made by a process that comprises the steps of (a) forming an intermediate guard tooth (11?) having a protrusion (11 a1) that extends beyond a skin contact edge (L2), (b) bending the protrusion (11a1) of the intermediate guard tooth (11?) over to form a bent-over portion (11a) of the intermediate guard tooth (11?), and (c) applying energy to the bent-over portion (11a) so that a molten tip portion (11 b) is formed. Even for thin base sheets (10), a large sized thickened tip (11d) can be formed and injuries induced by hooking of trimmer teeth can effectively be avoided. The invention is also concerned with a method of manufacturing a trimmer comb.
