Abstract

A panel-insert assembly including a panel having a core and a skin layer positioned over the core, wherein the skin layer defines an opening therein, and an insert positioned below the skin layer, wherein the insert is aligned with the opening.

First claim

What is claimed is:

1. A panel-insert assembly comprising:
a panel comprising a core and a skin layer positioned over said core, wherein said skin layer defines an opening that is elongated along an opening axis and comprises a maximum length; and
an insert defining a vertical axis and comprising a body comprising a bore, wherein said body extends about said bore and defines an engagement surface, wherein said engagement surface comprises a solid, elongated shape having an outer periphery extending about said vertical axis, said outer periphery defining a major dimension extending along a major axis and a minor dimension extending along a minor axis, said minor axis being perpendicular to said major axis, and said major dimension being greater than said minor dimension and said minor dimension is less than or equal to said maximum length, wherein said insert is positioned vertically below said skin layer between said skin layer and said core, and is oriented relative to said opening such that said major axis is substantially parallel with said opening axis and said outer periphery is entirely radially outside of said opening.

2. The panel-insert assembly of claim 1 wherein said panel is a sandwich panel and further comprises a second skin layer, wherein said core is positioned between said skin layer and said second skin layer.

3. The panel-insert assembly of claim 1 wherein said bore is threaded.

4. The panel-insert assembly of claim 1 wherein said core comprises a honeycomb structure.

5. The panel-insert assembly of claim 1 wherein said opening is obround when viewed along said vertical axis.

6. The panel-insert assembly of claim 1 wherein said engagement surface is substantially planar.

7. The panel-insert assembly of claim 1 wherein said engagement surface flushly abuts said skin layer.

8. The panel-insert assembly of claim 1 wherein said major dimension is about 1.1 to about 3 times greater than said minor dimension.

9. The panel-insert assembly of claim 1 wherein said major dimension is about 1.5 to about 2 times greater than said minor dimension.

10. The panel-insert assembly of claim 1 wherein said body is ellipse-shaped.

11. The panel-insert assembly of claim 1 wherein said insert comprises a combination of materials.

12. A panel-insert assembly comprising:
a sandwich panel comprising:
a core having a first major side and a second major side opposed from said first major side;
a first skin layer positioned over said first major side, wherein first skin layer defines an opening, and wherein said opening is elongated along an opening axis and comprises a maximum length; and
a second skin layer positioned over said second major side; and

an insert defining a vertical axis and comprising a body comprising a threaded bore, said body extends about said bore and defines an engagement surface, wherein said engagement surface comprises a solid, elongated shape having an outer periphery extending about said vertical axis, said outer periphery defining a major dimension extending along a major axis and a minor dimension extending along a minor axis, said minor axis being perpendicular to said major axis, and said major dimension being greater than said minor dimension and said minor dimension is less than or equal to said maximum length, wherein said insert is positioned vertically below said first skin layer between said first skin layer and said core, and is oriented relative to said opening such that said major axis is substantially parallel with said opening axis and said outer periphery is entirely radially outside of said opening.

13. The panel-insert assembly of claim 12 wherein said core comprises a honeycomb structure.

14. The panel-insert assembly of claim 12 wherein said major dimension is about 1.1 to about 3 times greater than said minor dimension.
