A functional element arrangement which includes a functional element which is to be mounted on a component, especially but not exclusively on a brittle or non-rigid component made of a material containing cavities or pores, e.g. plastic, wood, metal foams, plastic or metal filled with hollow bodies, or another relatively soft material, selectively embodied as a sandwich construction or as a composite material e.g. in the form of a single layered or multilayered structure comprising, for example, two layers of sheet metal or plastic and a core made of one of the above-mentioned materials. The invention is characterized in that it is provided with an auxiliary assembly element which enables the functional element to be blocked using forming techniques when it is mounted on the component in a riveting process or a stamping and riveting process. The invention is further characterized in that, preferably, at least one device is provided to ensure rotational security between the functional element and the component and/or between the auxiliary assembly element and the component. The invention also relates to a functional element, an auxiliary assembly element, an assembled component and various methods for producing assembled components.
Functional element arrangement (18) having a functional element (20) for attachment to a component (10) comprising a material composite, characterised in that
Functional element arrangement (18) in accordance with one of the preceding claims, characterised in that the component consists of at least two components (10) placed against one another.
Functional element arrangement (18) in accordance with one of the preceding claims, characterised in that both the functional element (20) and also the auxiliary joining part (22) are deformed during the carrying out of the riveting process to form the locked connection.
Functional element arrangement (18) in accordance with one of the preceding claims, characterised in that functional element (20) and the auxiliary joining part (22) are joined together and with the component coming from opposite sides of the component (10).
Functional element arrangement (1) in accordance with one of the preceding claims, characterised in that the functional element (20) and the auxiliary joining part (22) each have a flange (32, 40) forming a contact surface (34, 43) against which the component (10) comes into contact, i.e. between which the component is trapped, i.e. clamped.
Functional element arrangement (18) in accordance with one of the preceding claims, characterised in that the functional element (20) is provided with a head section (24) and a shaft section (26) and has, in the region of the head section (24) or in the region of the transition from the head section (24) to the shaft section (26) a rivet section (30) for the rivet connection to the auxiliary joining part (22).
Functional element arrangement (18) in accordance with one of the preceding claims, characterised in that the auxiliary joining part (22) is a sheet metal part.
Functional element arrangement (18) in accordance with one of the preceding claims, characterised in that the auxiliary joining part (22) is formed as plate-like part, the marginal region (40) of which forms a contact surface (43) against which the component (10) comes into contact and the dish (42) of which is to be arranged in a ring recess (50) or stepped bore (46) of the component (10) and in that the functional element (20) can be riveted to the base (44) of the dish.
Functional element arrangement (18) in accordance with one of the preceding claims, characterised in that the auxiliary joining part (22) is formed as a flat disc, the marginal region (40) of which forms a contact surface (43) against which the component comes into contact and in that the functional element (20) is rivetable with the central region of the disc.
Functional element arrangement (18) in accordance with one of the preceding claims, characterised in that the functional element (20) and/or the auxiliary joining part (22) is provided with an adhesive at at least one surface region which, on attachment to the component (10), enters into contact with the latter and/or with the other respective part (auxiliary joining part or functional element).
Functional element arrangement (18) in accordance with one of the preceding claims, characterised in that the auxiliary joining part (22) is a plate-like part, the edge region (40) of which forms a contact surface (43) against which the component (10) comes into contact, with this edge region (40) being initially conically shaped and diverging in the direction of the dish (42) of the plate-like part, in that the dish (42) of the plate-like part is formed to receive a rivet section (30) of the functional element (20) which can be received into the dish (42) from the side of the edge region, and in that the rivet connection can be brought about while pressing the edge region (40) of the plate-like part flat and with reforming of the base region (44) (FIG. 2, FIG. 3).
