  • Patent number: 7480971
    Abstract: Disclosed are a method and a device for mounting a fastening element (12) to a part (13), e.g. a sheet metal part, said fastening element comprising a head piece (14) with a tubular rivet section (16) which is disposed concentric to an axis of symmetry (18) of the fastening element (12) or a fastening section (20) of the fastening element (12) and extends into the head piece via a radially extending contact surface (22). The rivet section (16) is guided through the part (12) so as to form a hole in said part, and the rivet section (12) is flanged such that the part is clamped between the contact surface and the flanged rivet section in the area of the hole.

  • Publication number: 20050158142
    Abstract: The invention relates to a functional element for attaching to a sheet metal part, such as for example a nut element or a bolt element comprising a body section or head section, which has a requisite cylindrical part on one axial end and runs into a cylindrical rivet section on its other axial end. Said element is characterised in that the body section is provided with an essentially cone-shaped region between the first axial end or a cylindrical section that may be provided there and the rivet section, said region forming a bearing surface for a corresponding cone-shaped region of a sheet metal part and that the cylindrical part, if present, has a diameter at the border with the cone-shaped region that is no greater than the maximum diameter of said cone-shaped region. When the functional element is attached to the sheet metal part, the narrow end of the cone-shaped region of said metal part is clamped in an annular protrusion, formed by the rivet section.
