Barrel nut retention apparatus

An apparatus for retaining a barrel nut within a cylindrical bore in a panel comprising:

• a barrel nut comprised of a threaded bore having a longitudinal axis, and a partially cylindrical base portion having opposed first and second shoulders on the outer extremity thereof, and further having opposed first and second end surfaces at the outer extremity thereof, said shoulders projecting away from the threaded bore;
• and
• retaining means comprised of:
• a resilient member having a first portion and a second portion being positioned on opposite sides of the threaded bore and being seated on said opposed shoulders in a plain generally perpendicular to the longitudinal axis, a part of said first portion and of said second portion being adapted to engage the panel when the apparatus is installed within said cylindrical bore, and a third portion disposed between said first and second portions and integrally connecting said first and second portions, said third portion being engaged with said first end surface in a plane generally parallel to the longitudinal axis;
• and a supporting member connecting said first and second portions, said supporting member being engaged with said second end surface in a plane generally parallel to the longitudinal axis;
• wherein said first portion and said second portion are each comprised of two straight segments joined together so that the juncture of said segments engages the panel when the apparatus is installed within said cylindrical bore.

An apparatus for retaining a barrel nut within a cylindrical bore in a panel so that the barrel nut is capable of threadedly receiving a bolt extending through a bolt hole in the panel, the bolt hole being oriented transversely to the cylindrical bore, the apparatus comprising:

• a barrel nut comprised of a threaded bore having a longitudinal axis, and a partially cylindrical base portion sized to fit into the cylindrical bore in the panel and having opposed first and second shoulders on the outer extremity thereof, and further having opposed first and second end surfaces at the outer extremity thereof, said shoulders projecting away from the threaded bore;
• and
• a retaining clip adapted to be positioned within the cylindrical bore in the panel, said retaining clip comprised of:
• a resilient member having a first portion and a second portion being positioned on opposite sides of the threaded bore and being seated on said opposed shoulders in a plane generally perpendicular to the longitudinal axis, said first portion and said second portion being both curved and convex in relation to the longitudinal axis, a part of said first portion and of said second portion being adapted to frictionally engage the panel when the apparatus is installed within said cylindrical bore, and a third portion disposed between said first and second portions and integrally connecting said first and second portions, said third portion being frictionally engaged with said first end surface in a plane generally parallel to the longitudinal axis;
• and a supporting member connecting said first and second portions, said supporting member being frictionally engaged with said second end surface in a plane generally parallel to the longitudinal axis;
• wherein said first portion and said second portion both have cylindrical ends adjacent to said second end surface in a plane generally parallel to the longitudinal axis, and said supporting member is a hollow cylindrical tube having said ends inserted in opposite extremities thereof.
