Abstract

A fastener assembly, which may be configured to be removably secured within an opening of a component, may include a pin including a plurality of locking members, and a grommet including a plurality of reciprocal retaining features configured to snapably retain the plurality of the locking members in a locked state in which the fastener assembly is configured to be inserted into the opening of the component. The plurality of locking members are removed from the reciprocal retaining features in a securing state in which the fastener assembly is secured within the opening formed through the component.

First claim

The invention claimed is:

1. A fastener assembly comprising:
a pin including at least one locking member or at least one reciprocal retaining feature; and
a grommet including the other of the at least one locking member or the at least one reciprocal retaining feature,
wherein the at least one locking member is configured to be securely retained by the at least one reciprocal retaining feature in a locked state in which the fastener assembly is configured to be inserted into an opening formed through a component, and wherein the at least one locking member is removed from the at least one reciprocal retaining feature in a securing state in which the fastener assembly is secured within the opening formed through the component,
wherein the at least one locking member comprises a column including at least one projection and having a T-shaped axial cross section.

2. The fastener assembly of claim 1 , wherein the at least one locking member further comprises at least one locking protuberance extending from a planar wall.

3. The fastener assembly of claim 1 , wherein the at least one reciprocal retaining feature comprises at least one notch, groove, or channel that is configured to snapably retain the at least one locking member.

4. The fastener assembly of claim 1 , wherein the grommet comprises a plurality of securing legs configured to outwardly expand in the securing state and pinch together in the locked state, and wherein each of the plurality of securing legs comprises the at least one locking member or the at least one reciprocal retaining feature.

5. The fastener assembly of claim 1 , wherein the pin comprises the at least one locking member extending from a wall, wherein the at least one locking member includes at least one first locking protuberance and at least one second locking protuberance, wherein one of the at least one first locking protuberance and the at least one second locking protuberance comprises the column.

6. The fastener assembly of claim 5 , wherein the at least one first locking protuberance is positioned to a first side of a central diametric plane of the pin, wherein the at least one second locking protuberance is positioned to a second side of the central diametric plane of the pin, and wherein the first side is opposite the second side.

7. The fastener assembly of claim 5 , wherein at least a portion of the at least one first locking protuberance is positioned at a different level than an entirety of the at least one second locking protuberance.

8. A fastener assembly configured to be removably secured within an opening of a component, the fastener assembly comprising:
a pin including a plurality of locking members; and
a grommet including a plurality of reciprocal retaining features configured to snapably retain the plurality of the locking members in a locked state in which the fastener assembly is configured to be inserted into the opening of the component, and wherein the plurality of locking members are removed from the reciprocal retaining features in a securing state in which the fastener assembly is secured within the opening formed through the component,
wherein at least one of the plurality of locking members comprises a column including at least one projection and having a T-shaped axial cross section.

9. The fastener assembly of claim 8 , wherein at least one of the plurality of locking members comprises at least one locking protuberance extending from a planar wall.

10. The fastener assembly of claim 8 , wherein each of the plurality of reciprocal retaining features comprises at least one notch, groove, or channel that is configured to snapably retain a respective one of the plurality of locking members.

11. The fastener assembly of claim 8 , wherein the grommet comprises a plurality of securing legs configured to outwardly expand in the securing state and pinch together in the locked state, and wherein one of the plurality of reciprocal retaining features is formed on one of the plurality of securing legs.

12. The fastener assembly of claim 8 , wherein the pin comprises a wall that includes at least two of the plurality of locking members, wherein the at least two of the plurality of locking members comprises at least one first locking protuberance and at least one second locking protuberance.

13. The fastener assembly of claim 12 , wherein the at least one first locking protuberance is positioned to a first side of a central diametric plane of the pin, wherein the at least one second locking protuberance is positioned to a second side of the central diametric plane of the pin, and wherein the first side is opposite the second side.

14. The fastener assembly of claim 12 , wherein at least a portion of the at least one first locking protuberance is positioned at a different level than an entirety of the at least one second locking protuberance.

15. A fastener assembly configured to be removably secured within an opening of a component, the fastener assembly comprising:
a pin including first and second locking protuberances extending from a planar wall and first and second columns positioned with respect to opposite sides of the planar wall, wherein each of the first and second columns includes first and second projections, respectively; and
a grommet including a plurality of securing legs, wherein each of the plurality of securing legs includes a reciprocal retaining feature configured to snapably retain one of the first locking protuberance, the second locking protuberance, the first projection, or the second projection in a compact locked state in which the fastener assembly is configured to be inserted into the opening of the component, wherein each of the plurality of reciprocal retaining features comprises at least one notch, groove, or channel that is configured to snapably retain a respective one of the first locking protuberance, the second locking protuberance, the first projection or the second projection, and wherein the first and second locking protuberances and the first and second projections are removed from the reciprocal retaining features in an expanded securing state in which the fastener assembly is secured within the opening formed through the component.

16. The fastener assembly of claim 15 , wherein the first locking protuberance is positioned to a first side of a central diametric plane of the pin, wherein the second locking protuberance is positioned to a second side of the central diametric plane of the pin, wherein the first side is opposite the second side.

17. The fastener assembly of claim 15 , wherein axial cross-sections of the first and second columns are T-shaped.

18. The fastener assembly of claim 15 , wherein the plurality of securing legs are configured to outwardly expand in the expanded securing state and pinch together in the locked state.

19. The fastener assembly of claim 15 , wherein at least a portion of the first locking protuberance is positioned at a different level than an entirety of the second locking protuberance.

20. The fastener assembly of claim 15 , wherein a first portion of the first locking protuberance is positioned at a different level than a second portion of the second locking protuberance.
