Abstract

In some examples, an apparatus comprises a surface and at least one flange extending from the surface. The fitting is operable to rotate from a first angular position to a second angular position based on contact between the at least one flange and a fastener and a torque applied to the fastener. In the first angular position, a gap separates the at least one flange from a barrier. In the second angular position, the at least one flange prevents rotation of the fastener based on contact between the barrier and the at least one flange. In some embodiments, the at least one flange comprises a plurality of flanges.

First claim

What is claimed is:

1. An assembly to support a fastener, the assembly comprising:
a barrier comprising at least a portion of a structure to which the assembly and fastener are installed; and
a fitting comprising:
a support surface, wherein at least a portion of the support surface is enclosable between opposite ends of the fastener; and
a first flange and a second flange extending from the support surface, wherein the first flange is perpendicular to the second flange; and

wherein the fitting is operable to rotate from a first angular position to a second angular position based on contact between the first flange and the fastener and a torque applied to the fastener, and
wherein:
in the first angular position, a gap separates the second flange from the barrier, and
in the second angular position, the second flange is operable to prevent rotation of the fastener based on contact between the barrier and the second flange.

2. The assembly of claim 1 , wherein the fastener is configured to enclose at least a portion of the support surface of the fitting between opposite ends of the fastener.

3. The assembly of claim 2 , wherein the support surface of the fitting comprises an opening, and the fastener extends through the opening.

4. The assembly of claim 1 , wherein the fastener comprises a shaft, a head attached to the shaft, and a nut operable to couple to the shaft.

5. The assembly of claim 4 , wherein the first flange is operable to contact the head of the fastener, and wherein the nut is operable to apply the torque to the shaft of the fastener.

6. The assembly of claim 1 , wherein the first flange and the second flange are located around an opening in the support surface of the fitting.

7. The assembly of claim 1 , wherein a difference between the first angular position and the second angular position is less than or equal to seven degrees.

8. The assembly of claim 1 , wherein the barrier comprises at least a portion of an aircraft.

9. An aircraft comprising:
an aircraft component;
a fastener operable to attach the aircraft component to the aircraft; and
an apparatus operable to support the fastener, the apparatus comprising:
a surface, wherein at least a portion of the surface is enclosable between opposite ends of the fastener;
a first flange and a second flange extending from the surface, wherein the first flange is perpendicular to the second flange; and

wherein the apparatus is operable to rotate from a first angular position to a second angular position based on contact between the first flange and the fastener and a torque applied to the fastener, and
wherein:
in the first angular position, a gap separates the second flange from a barrier comprising at least a portion of the aircraft component, and
in the second angular position, the second flange is operable to prevent rotation of the fastener based on contact between the barrier and the second flange.

10. The aircraft of claim 9 , wherein the fastener is operable to enclose at least a portion of the surface of the apparatus between opposite ends of the fastener.

11. The aircraft of claim 10 , wherein the surface of the apparatus comprises an opening, and the fastener extends through the opening in the surface of the apparatus.

12. The aircraft of claim 9 , wherein the fastener comprises a shaft, a head attached to the shaft, and a nut operable to couple to the shaft.

13. The aircraft of claim 12 , wherein the first flange is operable to contact the head of the fastener, and wherein the nut is operable to apply the torque to the shaft of the fastener.

14. A system comprising:
an aircraft component;
a fastener operable to attach the aircraft component to an aircraft;
a fitting operable to support the fastener, the fitting comprising:
a surface, wherein at least a portion of the surface is enclosable between opposite ends of the fastener;
a first flange and a second flange extending from the surface, wherein the first flange is perpendicular to the second flange; and
wherein the fitting is operable to rotate from a first angular position to a second angular position based on contact between the first flange and the fastener and a torque applied to the fastener, and

wherein:
in the first angular position, a gap separates the second flange from a barrier comprising at least a portion of the aircraft component, and
in the second angular position, the second flange is operable to prevent rotation of the fastener based on contact between the barrier and the second flange.

15. The system of claim 14 , wherein the fastener is operable to enclose at least a portion of the surface of the fitting between opposite ends of the fastener.

16. The system of claim 15 , wherein the surface of the fitting comprises an opening, and the fastener extends through the opening in the surface of the fitting.

17. The system of claim 14 , wherein the fastener comprises a shaft, a head attached to the shaft, and a nut operable to couple to the shaft.

18. The system of claim 17 , wherein the first flange is operable to contact the head of the fastener, and wherein the nut is operable to apply the torque to the shaft of the fastener.
