Abstract

An assembly is provided that includes a first component, a second component, a plurality of retainers and a fastener. The first component is configured with a plurality of first apertures. The second component is configured with a plurality of second apertures. Each of the retainers includes a pin and an arm projecting out from an end of the pin. The pin of each of the retainers is mated with a respective one of the first apertures and a respective one of the second apertures. The fastener is configured to fixedly connect the arm of each of the retainers to the first component.

First claim

What is claimed is:

1. An assembly, comprising:
a first component configured with a plurality of first apertures;
a second component configured with a plurality of second apertures;
a plurality of retainers, each of the retainers including a pin and an arm projecting out from an end of the pin, and the pin of each of the retainers mated with a respective one of the first apertures and a respective one of the second apertures; and
a fastener configured to fixedly connect the arm of each of the retainers to the first component;
the arm of a first of the retainers including a retainer head and a bridge that extends between and is connected to the retainer head and the pin of the first of the retainers; and
the retainer head stacked between a head of the fastener and the first component where the fastener fixedly connects the first of the retainers to the first component.

2. The assembly of claim 1 , wherein the fastener comprises a bolt.

3. The assembly of claim 1 , wherein the fastener is configured to
fixedly connect the arm of each of the retainers to a mount of the first component where the fastener is in a first position;
disconnect the arm of each of the retainers from the mount where the fastener is in a second position; and
the fastener is connected to the first component in the first position and is disconnected from the first component in the second position.

4. The assembly of claim 1 , wherein the fastener is configured to
fixedly connect the arm of each of the retainers to a mount of the first component where the fastener is in a first position;
disconnect the arm of each of the retainers from the mount where the fastener is in a second position; and
the fastener is connected to the first component in the first position and the second position.

5. The assembly of claim 1 , wherein the arm of each of the retainers is only fixedly connected to the first component by the fastener.

6. The assembly of claim 1 , wherein the retainer head extends partially circumferentially about a shaft of the fastener where the fastener fixedly connects the first of the retainers to the first component.

7. The assembly of claim 1 , wherein
the arm of a second of the retainers includes a second retainer head and a second bridge that extends between and is connected to the second retainer head and the pin of the second of the retainers;
the second retainer head is stacked between the head of the fastener and the first component where the fastener fixedly connects the second of the retainers to the first component; and
the second retainer head does not contact the retainer head where the fastener fixedly connects the first and the second retainers to the first component.

8. The assembly of claim 1 , wherein
the arm of a second of the retainers includes a second retainer head and a second bridge that extends between and is connected to the second retainer head and the pin of the second of the retainers;
the second retainer head is stacked between the head of the fastener and the first component where the fastener fixedly connects the second of the retainers to the first component; and
the second retainer head interlocks with the retainer head where the fastener fixedly connects the first and the second retainers to the first component.

9. The assembly of claim 1 , wherein the arm of the first of the retainers is configured with a slot that receives a protrusion of the first component.

10. The assembly of claim 1 , wherein
the pin of a first of the retainers projects along an axis through the respective one of the first apertures and at least partially into the respective one of the second apertures;
the first of the retainers is configured to rotate about the axis between a first position and a second position while the fastener is connected to the first component;
the fastener is configured to retain the pin of the first of the retainers within the respective one of the first apertures and the respective one of the second apertures where the first of the retainers is in the first position; and
the pin of the first of the retainers is operable to slide along the axis and move out of the respective one of the first apertures and the respective one of the second apertures where the first of the retainers is in the second position.

11. The assembly of claim 1 , wherein
the pin of a first of the retainers projects along an axis through the respective one of the first apertures and at least partially into the respective one of the second apertures;
the first of the retainers is configured to translate along the axis between a first position and a second position while the fastener is connected to the first component;
the fastener is configured to retain the pin of the first of the retainers within the respective one of the first apertures and the respective one of the second apertures where the first of the retainers is in the first position; and
the pin of the first of the retainers is operable to slide along the axis and move out of the respective one of the second apertures where the first of the retainers translates from the first position to or towards the second position.

12. The assembly of claim 11 , wherein the fastener is configured to retain the pin of the first of the retainers within the respective one of the first apertures where the first of the retainers is in the second position.

13. The assembly of claim 11 , wherein the first of the retainers is operable to translate along the axis between the first position and the second position while the fastener is connected to the first component without rotating about the axis.

14. The assembly of claim 1 , wherein
the pin of a first of the retainers projects along an axis through the respective one of the first apertures and into the respective one of the second apertures; and
the pin of the first of the retainers is configured with a circular cross-sectional geometry when viewed in a plane perpendicular to the axis.

15. The assembly of claim 1 , wherein a configuration of a first of the retainers is a mirror image of a configuration of a second of the retainers where the retainers are fixedly connected to the first component.

16. The assembly of claim 1 , wherein a configuration of a first of the retainers is identical to a configuration of a second of the retainers.

17. The assembly of claim 1 , wherein the first component and the second component are configured as components of a gas turbine engine.

18. An assembly of a gas turbine engine, comprising:
a first component of the gas turbine engine comprising a first flange, a second flange and a mount, the first flange configured with a plurality of first flange apertures, and the second flange configured with a plurality of second flange apertures;
a second component of the gas turbine engine arranged between the first flange and the second flange, the second component configured with a plurality of second component apertures;
a first retainer including a first pin and a first arm cantilevered from an end of the first pin, the first pin projecting along a first axis though a first of the first flange apertures, through a first of the second component apertures and at least partially into a first of the second flange apertures;
a second retainer including a second pin and a second arm cantilevered from an end of the second pin, the second pin projecting along a second axis though a second of the first flange apertures, through a second of the second component apertures and at least partially into a second of the second flange
