Combination of functional element and pressure plate
View Patent ↗The invention relates to a combination of a functional element having a flange section and a connection section, in particular a rivet element, and a pressure plate, in particular a pressure plate having an opening, for attachment to a component, in particular to a panel of composite material or sheet metal, wherein the functional element and the pressure plate are formed to be arranged on opposite sides of a hole of the component and are to be connected together via the connection section which extends through the hole, in particular by riveting, in order to clamp a region of the component surrounding the hole between the flange section and the pressure plate and wherein the pressure side of the pressure plate confronting the component in the attached state is provided with a means providing security against rotation.
1. A combination of a functional element ( 11 ) having a flange section ( 13 ) and a connection section ( 15 ) and a pressure plate ( 17 ) for attachment to a component ( 19 ) having a hole ( 21 ) therein and a region surrounding the hole, the pressure plate having an opening
wherein the functional element ( 11 ) and the pressure plate ( 17 ) are formed to be arranged on respective first and second oppositely disposed sides of the hole ( 21 ) of the component ( 19 ) and to be connected together in an attached state via the connection section ( 15 ) which extends through the hole ( 21 ) in order to clamp the region of the component ( 19 ) surrounding the hole ( 21 ) between the flange section ( 13 ) and the pressure plate ( 17 ) and wherein the plate has a contour which differs from a circular shape and wherein the contour of a top side of the plate substantially corresponds to the contour of a bottom side of the plate and that these contours differ from a circular shape and a substantially flat pressure side confronting the adjacent second side of the component, wherein the contour of the pressure side of the pressure plate ( 17 ) confronting the component ( 19 ) is adapted to be at least slightly pressed into the component to provide a security against rotation in the attached state.
2. The combination in accordance with claim 1 , wherein the component is a panel of material consisting of at least one of a composite material and a sheet metal material.
3. The combination in accordance with claim 1 , wherein a contour of the pressure side has a circular basic shape from which at least one section ( 23 ) is removed.
4. The combination in accordance with claim 3 , wherein the missing section ( 23 ) is selected from the group comprising a sector, a segment, a cutout and a bay.
5. The combination in accordance with claim 1 , wherein the pressure side is bounded with a sharp edge at least regionally.
6. The combination in accordance with claim 1 , wherein a side of the pressure plate ( 17 ) remote from the component ( 19 ) in the attached state is provided with a collar ( 27 ) surrounding the opening.
7. The combination in accordance with claim 6 , wherein the collar ( 27 ) is adapted to cooperate in the attached state with a rivet section ( 29 ) forming the connection section ( 15 ).
8. The combination in accordance with claim 1 , wherein the outer diameter of the pressure plate ( 17 ) is larger than a largest diameter of the flange section ( 13 ) of the functional element ( 11 ).
