Abstract
The present invention relates to a flange that includes a base region, a first raised region, a second raised region, a first sloped region between the base region and the first raised region, and a second sloped region between the base region and the second raised regions, wherein the first and second sloped regions extend through a gap region between the first and second raised regions, and wherein the first and second sloped regions define multiple concave and convex regions in multiple planes of the flange so as to reduce stress within the flange.
Claims17
A fuel tank flange, comprising:
- a flange body including a base region;
- a first raised region;
- a second raised region;
- a first sloped region extending between said base region and said first raised region wherein said first raised region is positioned vertically upwardly from said base region as measured along a vertical axis of said flange body;
- a second sloped region extending between said base region and said second raised region wherein said second raised region is positioned vertically upwardly from said base region as measured along a vertical axis of said flange body;
- a first component aperture positioned in said first raised region;
- a second component aperture positioned in said second raised region;
- and
- wherein said first sloped region defines a plurality of alternating convex curved regions and concave curved regions positioned completely around said first raised region, and wherein said second sloped region defines a plurality of alternating convex curved regions and concave curved regions positioned completely around said second raised region.

A fuel tank flange assembly, comprising:
- a flange body including a base region, a first raised region extending upwardly from said base region, a second raised region extending upwardly from said base region, a gap region position between said first raised region and said second raised region, a first sloped region position between said base region and said first raised region in said gap region, a second sloped region position between said base region and said second raised region in said gap region, said first sloped region including a curved region that is concave with respect to said first raised region, said second sloped region including a curved region that is convex with respect to said second raised region, and wherein said concave curved region of said first sloped region is positioned adjacent said convex curved region of said second sloped region in said gap region;
- and
- wherein said first sloped region defines a plurality of alternating convex curved regions and concave curved regions positioned completely around said first raised region, and wherein said second sloped region defines a plurality of alternating convex curved regions and concave curved regions positioned completely around said second raised region.
A flange assembly, comprising:
- a flange body including a base region that defines a top surface, a first raised region positioned upwardly from said top surface of said base region, a second raised region positioned upwardly from said top surface of said base region, a gap region position between said first and said second raised regions, a first sloped region extending between said base region and said first raised region in said gap region, and a second sloped region extending between said base region and said second raised region in said gap region;
- wherein said first sloped region in said gap region defines an upper sloped region that is concave with respect to said top surface of said base region and a lower sloped region that is convex with respect to said top surface of said base region;
- wherein said second sloped region in said gap region defines an upper sloped region that is concave with respect to said top surface of said base region and a lower sloped region that is convex with respect to said top surface of said base region;
- a flange axis positioned perpendicular to said top surface of said base region, wherein said first sloped region defines three inflection lines positioned within said gap region, said three inflection lines of said first sloped region defining a change in curvature of said first sloped region with respect to said flange axis, and wherein said second sloped region defines three inflection lines positioned within said gap region, said three inflection lines of said second sloped region defining a change in curvature of said second sloped region with respect to said flange axis;
- and
- wherein said first sloped region includes an alternating pattern of concave and convex curvatures extending completely around said first raised region, wherein said concave and convex curvatures of said first sloped region are measured with respect to said flange axis, and said second sloped region includes an alternating pattern of concave and convex curvatures extending completely around said second raised region, wherein said concave and convex curvatures of said second sloped region are measured with respect to said flange axis.
