The present invention provides a fastening structure and a fastening method for fastening first and second components, ensuring a high degree of freedom in terms of bonding positions and objects, and reducing the number of holes in the components. Specifically, the present invention provides a fastening structure for fastening the first and second components, wherein said fastening structure comprises a pin that has non-helical grooves running in a circumferential direction and aligned along a longitudinal direction, and a collar that is fitted around said pin, and said pin is united with said first component by bonding one end of said pin in the longitudinal direction to said first component without forming a hole in said first component, and said second component has a hole for inserting said pin so that said collar is fitted around and swaged to said pin protruding through the hole.

To fasten a first component to a second component, a fastening clip has an integral, elongated structure with a first and a second fastening end. The first fastening end comprises an at least one-armed independent latching structure. The second fastening end is formed by a resilient clamp. The first and second latching structure act on an intermediate support structure. To connect the two components, the latching structure is latched in a component opening in a first component, and the second component is fastened between the support structure and a spring loop of the resilient clamp with the assistance of a cutout or a slot that is open on one side.

A component assembly includes a first component that has a first hole. The first hole has a non-circular cross section. A first portion of the first hole has a first radius of curvature and a second component. A pin extends from the second component and through the first hole. The pin has a non-circular cross section. A second portion of the pin has a second radius of curvature. The first radius of curvature and the second radius of curvature are substantially the same.

The concave part includes an open end portion having an inner diameter greater than an outer diameter of a tip end portion of a ball stud, a fitting portion which is connected to the open end portion and has an inlet smaller than the outer diameter of the tip end portion and in which the tip end portion is housed, and a plurality of slits which are formed in a fitting direction of the ball stud from the open end portion and arranged at a predetermined interval along the circumference of the concave part. The pull-out prevention part includes a plurality of first ribs located on extensions of the respective slits.

The invention relates to an anchor for arrangement in lightweight building boards, wherein a lightweight building board has a first covering layer and a second covering layer made from compact material that is stiff in compression, and a core layer, which is arranged between the covering layers and is made from material with a low density in comparison with the covering layers, in particular paper honeycomb, foam or solid wood of low density, having a first anchor part and a second anchor part, wherein the first and the second anchor part are designed to be movable relative to one another, in which a travel between a first end position and a second end position is limited, wherein the first end position is defined by means of first stop means on the first and the second anchor part, and the second end position is defined by means of second stop means on the first and the second anchor part.

A press-fit connection between a high-strength component and a press-fit element is characterized by a non-circular previously made hole into which the press-fit element having a collar is inserted. Here, the collar is merely upset and pressed against a hole rim without embracing an underside of the component. Preferably, the hole rim is widened in a longitudinal direction such that a form-locking connection acting in opposition to the longitudinal direction is formed. The non-circular hole geometry is produced with the aid of a punch of circular cross sectional geometry, in that a cutter of the punch has leading and recessed cutting regions, with the result that disrupted partial regions are formed.
