Abstract
A fastener system includes a fastener including a fastener first end and a longitudinally opposed fastener second end, and an anchor configured to receive and capture the fastener upon rotation of the fastener in a first direction, wherein the anchor is further configured to engage the fastener first end upon complete rotation of the fastener in the first direction, and the anchor is further configured to prohibit further rotation in a second direction, opposite the first direction, upon engagement with the fastener first end.
Claims20
A fastener system comprising:
- a fastener comprising a fastener first end, a longitudinally opposed fastener second end, and a fastener channel extending longitudinally through said fastener;
- and
- an anchor comprising:
- an anchor channel extending longitudinally through said anchor;
- a lock plate;
- and
- a biasing element connected to said lock plate;
- and wherein:
- said anchor is configured to receive and capture said fastener upon rotation of said fastener in a first direction;
- said biasing element is configured to bias said lock plate into engagement with said fastener first end upon complete rotation of said fastener in said first direction;
- said lock plate is configured to prohibit further rotation of said fastener in a second direction, opposite said first direction, upon interlocking engagement with said fastener first end;
- and
- with said fastener received by said anchor, said fastener channel and said anchor channel are aligned and in fluid communication with each other to enable a flow of a cooling airflow to pass through said anchor and said fastener.

A structure comprising:
- a first structure member comprising a first fastener aperture;
- a second structure member comprising a second fastener aperture, wherein said second structure member abuts said first structure member and said second fastener aperture is aligned with said first fastener aperture;
- a nut plate comprising a nut plate receptacle, wherein said nut plate is coupled to said first structure member within said first fastener aperture and is rotationally fixed relative to said first structure member;
- a nut comprising a nut recess, wherein said nut is located in said nut plate receptacle of said nut plate and is rotationally fixed relative to said nut plate;
- a lock plate located in said nut recess of said nut, wherein said lock plate is longitudinally moveable within said nut recess and is rotationally fixed relative to said nut;
- a biasing element connected to said lock plate;
- and
- a fastener comprising a fastener first end, wherein said fastener is inserted through said second fastener aperture and said nut recess and is captured by said nut;
- and wherein:
- said biasing element biases said lock plate into contact engagement with said fastener first end upon complete rotation of said fastener in a first direction and further biases said lock plate into interlocking engagement with said fastener first end upon said contact engagement of said lock plate with said fastener first end and further rotation of said fastener in said first direction or a second direction, opposite said first direction;
- and
- said lock plate prohibits further rotation of said fastener in said second direction upon said interlocking engagement with said fastener first end.

A fastener system comprising:
- an anchor assembly comprising:
- a nut plate comprising a nut plate receptacle;
- a nut comprising a nut recess, wherein said nut is located in said nut plate receptacle of said nut plate and is rotationally fixed relative to said nut plate;
- a lock plate located in said nut recess of said nut, wherein said lock plate is longitudinally moveable within said nut recess and is rotationally fixed relative to said nut;
- and
- a biasing element located between said lock plate and said nut plate;
- and
- a fastener comprising a fastener first end;
- and wherein:
- said nut is configured to receive and capture said fastener upon rotation of said fastener in a first direction;
- said biasing element biases said lock plate into said nut recess and into engagement with said fastener first end upon complete rotation of said fastener in said first direction;
- and
- said lock plate prohibits further rotation of said fastener in a second direction, opposite said first direction, upon interlocking engagement with said fastener first end.
