MOUNTING APPARATUS FOR DYNAMICALLY LOADED STRUCTURAL JOINTS
A mounting structure apparatus for dynamically loaded structure joints is disclosed. The apparatus includes a first member having an aperture through a first surface and communicating with a counterbore in a second surface. A second member is included having a blind bore coaxial with the first member aperture. An insert is engageable with the counter bore, and a fastener is disclosed insertable into the first member aperture and interactive with the second member to join the first member to the second member.
1 . A mounting structure apparatus, comprising:
A first member having an aperture through a first surface and communicating with a counterbore in a second surface;
a second member having a blind bore coaxial with said first member aperture;
an insert engageable with said counter bore, and
a fastener insertable into said first member aperture and interactive with said second member blind bore to join said first member to said second member.
2 . The mounting apparatus of claim 1 , wherein said insert is a projection from a surface of the second member interactive with said counter bore in said first member, said insert having internal threads interactive with threads on said fastener.
3 . The mounting apparatus of claim 1 , wherein said insert is equipped with internal threads and external threads, said external insert threads engagable with threads in a blind aperture in said second member, and said blind bore is threaded to engage said fastener; said insert further including shoulder portions to engage said first member counterbore.
4 . The mounting apparatus of claim 1 , wherein said counterbore is substantially circular.
5 . The mounting apparatus of claim 1 , wherein said counterbore is oblong.
6 . The mounting apparatus of claim 1 , wherein said counterbore has a first dimension to accommodate said insert, and a second dimension smaller than said first dimension; said second dimension separated from said first dimension by a length L; said counterbore tapered from said first dimension to said second dimension.
7 . The mounting apparatus of claim 1 , wherein said second member has a counterbore complimentary with said blind bore; said insert engageable with said second member counterbore and said first member counterbore.
8 . The mounting apparatus of claim 7 , wherein said second member has a counterbore concentric with said blind bore.
