Lining fasteners and methods and apparatus therefor

摘要

Fastener assemblies, elements for fastener assemblies and methods of making and assembling elements for fastener assemblies, for example for insulation blanket fasteners such as those used on aircraft, may include a formed monolithic metal configuration having first and second side portions with a plurality of panel retaining elements arranged linearly along the side portions. A planar retaining element, for example a disc, may be assembled with the metal portion to form a fastener assembly, such as may be used to retain and insulation blanket. The planar retaining element may include a rolled edge, and if a coated part, may include surface projections to keep adjacent parts from sticking together during the coating process.

主权项

1. A fastener stud for a blanket insulation fastener assembly, the fastener stud comprising a monolithic metal post element and a support portion, the post element having two side portions spaced apart from each other, each side portion being supported at a support portion by a semi-circular bridge portion, wherein each side portion extends straight in a respective side direction away from the bridge portion, substantially tangent to respective portions of the bridge portion, and each side portion includes a plurality of first retaining surfaces at edge surfaces of the respective side portion, wherein each first retaining surface extends outward of the respective side portion in the respective side direction and wherein each first retaining surface on one side portion has a corresponding first retaining surface on the other side portion, the side portions being symmetrical about a longitudinal front-to-back plane parallel to a central axis of the post element, and a plurality of second retaining surfaces on the bridge portion wherein at least one second retaining surface corresponds to a pair of the first retaining surfaces at the same level as the second retaining surface and wherein the at least one second retaining surface extends parallel to the level of the first retaining surfaces.
