Abstract

A fastener-retaining system (100) is configured to securely couple a fastener (102) to a substrate (104). The fastener-retaining system (100) includes a compression-limiting bushing (106) including a tube defining a central passage (132), and a retainer (130) positioned within the central passage. The retainer (130) includes a first portion that securely connects to the bushing, and a second portion that is configured to securely connect to a portion of the fastener.

Claims

1. A fastener-retaining system that is configured to securely couple a fastener to a substrate, the fastener-retaining system comprising:

a compression-limiting bushing including a tube defining a central passage having a longitudinal axis; and

a retainer positioned within the central passage, wherein the retainer includes a first portion that securely connects to the bushing, and a second portion that is configured to securely connect to a portion of the fastener, wherein the second portion includes one or more arcuately-shaped, inwardly-directed segments that bow toward a central longitudinal axis of the retainer and longitudinally extend along the retainer from a first edge to a second edge of the retainer such that the arcuately-shaped, inwardly-directed segments comprise the first edge and second edge, and wherein the one or more inwardly-directed segments are configured to abut an outer surface of the portion of the fastener, and wherein the retainer further comprises at least one securing member that is configured to securely couple to the substrate, the at least one securing member including at least one ramped surface and a catch that is configured to latch onto the substrate.

2. The fastener-retaining system of claim 1, wherein the retainer is configured to be securely positioned between an interior surface of the bushing and an outer surface of the fastener.

3. The fastener-retaining system of claim 1, wherein the retainer further comprises at least one extension leg extending from a retaining wall, wherein the at least one securing member extends from a distal end of the at least one extension leg.

4. The fastener-retaining system of claim 1, wherein the retainer further comprises a retaining wall that includes the first portion and the second portion.

5. The fastener-retaining system of claim 4, wherein the retaining wall comprises at least one outwardly-extending securing member.

6. The fastener-retaining system of claim 4, wherein the first portion includes one or more outwardly-directed segments that directly abut into an interior surface of the bushing, and wherein the second portion includes the one or more inwardly-directed segments that are configured to directly abut into the outer surface of the portion of the fastener.

7. The fastener-retaining system of claim 4, wherein the retaining wall has a clover shape.

8. A securing system comprising:

a fastener including a head connected to a shaft;

a substrate including a first surface and a second surface opposite from the first surface, wherein a hole is formed through the substrate from the first surface to the second surface; and

a fastener-retaining system that securely couples the fastener to the substrate, the fastener-retaining system comprising;

a compression-limiting bushing including a tube defining a central passage, wherein the bushing is positioned between the head of the fastener and the first surface of the substrate; and

a retainer positioned within the central passage of the bushing and defining a central longitudinal axis, wherein the retainer includes a retaining wall comprising a first portion that securely connects to the bushing, and a second portion that is configured to securely connect to the shaft of the fastener, wherein the second portion comprises at least one inwardly-directed segment that is configured to abut an outer surface of the shaft of the fastener, the inwardly-directed segment bowing toward the central longitudinal axis and longitudinally extending along the retainer, and wherein the retainer further comprises one or more securing members that include at least one ramped surface and a catch, the catch being configured to latch onto the substrate.

9. The securing system of claim 8, wherein the retainer is securely positioned between an interior surface of the bushing and an outer surface of the fastener.

10. The securing system of claim 8, wherein the retainer further comprises extension legs extending from a retaining wall, wherein each of the securing members extends from a distal end of respective one of the extension legs.

11. The securing system of claim 8, wherein the retainer further comprises a retaining wall that includes the first portion and the second portion.

12. The securing system of claim 11, wherein the retaining wall comprises at least one outwardly-extending securing member.

13. The securing system of claim 11, wherein the first portion includes outwardly-directed segments that directly abut into an interior surface of the bushing, and wherein the second portion includes inwardly-directed segments that directly abut into an outer surface of the portion of the fastener.

14. The securing system of claim 11, wherein the retaining wall has a clover shape.

15. A fastener-retaining system that is configured to securely couple a fastener to a substrate, the fastener-retaining system comprising:

a compression-limiting bushing including a tube defining a central passage; and

a retainer positioned within the central passage, wherein the retainer is configured to be securely positioned between an interior surface of the bushing and an outer surface of the fastener, wherein the retainer includes;

a clover-shaped retaining wall that defines a central longitudinal axis and includes a plurality of outwardly-directed segments that directly abut into an interior surface of the bushing to securely couple the retainer to the bushing, and a plurality of inwardly-directed segments that are configured to directly abut into an outer surface of a shaft of the fastener to securely connect the bushing to the fastener, wherein each of the inwardly-directed segments bow toward the central longitudinal axis, and wherein each of the inwardly-directed segments alternate with each of the outwardly-directed segments;

securing members that are configured to securely couple to the substrate, wherein each of the securing members comprises at least one ramped surface that is configured to latch onto the substrate.

16. The fastener-retaining system of claim 15, wherein the retainer further comprises extension legs extending from the retaining wall, wherein each of the securing members extends from a distal end of respective one of the extension legs.
