  • Patent number: 12459144
    Abstract: The invention relates to a handle for a wet razor including a handle section as well as a coupling section for detachably attaching a cutting unit to the handle. The coupling section comprises a housing section including a housing cavity, which has an insertion opening at the end directed toward the cutting unit and an operating opening. The coupling section furthermore comprises a connector including fastening elements, which engage in the housing section, and including a peg, which protrudes beyond the plane of the insertion opening. The coupling section furthermore comprises an ejector, which is inserted into the housing cavity so as to be axially displaceable, including a spring element, which axially urges the ejector into the housing cavity, and a ram, which during axial displacement of the ejector in the direction toward the cutting unit extends beyond the plane of the insertion opening.

  • Patent number: 9522472
    Abstract: The invention relates to a razor (01) having a handle (03), a cutting unit (02) and a coupling portion (04, 12) for attaching in a detachable manner the cutting unit (02) on the handle (03). The cutting unit (02) comprises a razor blades unit (06) having one or multiple razor blades, wherein the razor blades unit (06) can be pivoted about a pivot axis that extends parallel to the longitudinal extension of the razor blades. The coupling portion comprises a mounting (12) and a rod (04) that is pivoted in the mounting. The pivot axis of the pivot bearing that is formed between mounting (12) and rod (04) basically extends perpendicularly to the pivot axis of the razor blades unit and basically parallel to the longitudinal axis of the rod (04), wherein the pivot bearing allows the cutting unit (02) to rotate in relation to the handle (03) at a rotation angle of at least 2° and at the most 20°.

  • Patent number: 8146255
    Abstract: A razor blade unit including a blade housing to hold at least one blade with a cutting edge, and a cover connected to the blade housing. The cover faces the back edges of the blades, i.e., the edges opposite from the cutting edges. The blade housing has positioning notches to support the cutting edges. In addition, the cover can have recesses to support the back edges of the blades and an elastic component, which exerts a pressing force on the back edges of the blades.

  • Patent number: 8096054
    Abstract: A razor blade unit with a blade housing, in which several blades with cutting edges lying parallel to a skin contact plane are arranged, a coupling section, which can be connected preferably in a detachable manner to a handle, and a connecting section. The connecting section includes at least one film hinge between the blade housing and the coupling section, which hinge defines a pivot axis extending parallel to the skin contact plane, and an elastic damping component, which surrounds one or more sides of the film hinge and is formed both on the blade housing and on the coupling section. The razor blade unit also has a foam edge, arranged in front of the cutting edges (with respect to the shaving direction) of the blades to pretension the skin during shaving. The pivot axis extending through the film hinge is positioned between the forward boundary (with respect to the shaving direction) of the foam edge and the cutting edge lying closest to the foam edge.
