  • Patent number: 5070613
    Abstract: A razor head, especially in the form of a so-called razor blade unit, is disposed on the front end of a handle. A single or double razor blade rests in a fixed manner on a blade holder of a plastic housing. The razor blade or blades are fixedly secured on a spacer and form a blade holder that can essentially be inserted from above into the plastic housing onto the blade platform thereof. After insertion, the blade holder can be fixed in the plastic housing. For this purpose, either a fixation strip is placed upon the blade holder, or the plastic housing is plastically deformable in such a way that the blade holder is fixed in the plastic housing.

  • Patent number: 5029391
    Abstract: A twin-pivot-head razor with a head that has an outer body that is provided with a window to receive a separate subassembly in which is integrated the holding mechanism for the razor blade unit. Starting from a spring-loaded neutral position, the razor blade unit, via this holding mechanism, can carry out pivoting movements about an axis that is parallel to the cutting edge of the razor blade. The separate subassembly is also pivotable within the outer body about an axis that is perpendicular to the aforementioned pivot axis, whereby the neutral position is formed by a spring arrangement within the outer body.

    Abstract: A razor head, especially a razor blade unit, having a single or double razor blades fixedly disposed in a plastic housing and resting on a blade support of the housing. If a double razor blade is provided, a spacer is disposed between the two blades. To provide a razor head of simple construction with straightforward fixation for the razor blades in the housing, the housing has an opening for the blades that is accessible from above, with the blades being introduced into the opening from above and onto the blade support. A cover or cap is placed on the housing to thereby fixedly and firmly hold the cover in position thereon, with the single or double blades being fixed between the cover and the blade support.
