Abstract

An inset panel fastener anchors into honeycomb substrates employed in the aircraft industry. The inset panel fastener provides significantly increased load carrying capabilities with a simple inexpensive construction. The inset panel fastener includes a plastic casing and a central floating fastener element. The casing includes a body, disk and cap. The body is generally barrel shaped including a central chamber for holding the fastener element which is preferably a female fastener. The disk radially projects from the top of the body and includes a fill hole and vent hole. Meanwhile, the cap engages and covers the bottom of the barrel shaped body. The cap is affixed in place using a weld, such as a sonic weld.

Claims6

Dependent claims

An inset panel fastener for being received into a structure cavity for affixing objects to the structure, the inset panel fastener comprising:

a plastic casing including plastic body, a plastic disk and a plastic cap;
said plastic body including a cylindrical barrel having a top, a bottom and a bore extending through said body to form a central chamber, a fastener entrance located at the top of said body and a fastener access opening located at the bottom of said body;
said plastic disk radially projecting from said top of said body;
said disk having a diameter greater than the diameter of said body to form a cavity space around said body;
said disk further including a fill hole and a vent hole at the edge of said disk for allowing the injection of resin into said cavity space;
said plastic cap engaging said body and covering said fastener access opening;
a fastener floatingly disposed within said central chamber;
and
a weld affixing said plastic cap to said plastic body wherein the material of said plastic cap and plastic body both melt and coalesce to form a bond.
