Abstract

A bolt retainer, to position a bolt within a bolt receiving element of a component, is disclosed. The bolt retainer may include a tube structure. The bolt retainer may further include bolt engaging elements that extend from an inner surface of the tube structure to engage with the bolt. The bolt retainer may additionally include component engaging elements that extend from an outer surface of the tube structure to engage with the component.

First claim

What is claimed is:

1. A bolt retainer to position a bolt within a bolt receiving element of a component, the bolt retainer comprising:
a tube structure including a first end and a second end opposite the first end,
wherein the tube structure includes a seam between seam ends of a sheet that forms the tube structure, and
wherein the seam includes an interlocking component that prevents at least one of:
separation of the seam ends, or
longitudinal movement of the seam ends in opposite directions;

bolt engaging elements that extend inwardly from an inner surface of the tube structure to engage with the bolt,
wherein the bolt engaging elements are formed from individual inwardly bent cantilevered tabs of the tube structure, and
wherein the bolt engaging elements are formed between the first end and the second end; and

component engaging elements that extend outwardly from an outer surface of the tube structure to engage with the bolt receiving element of the component,
wherein the component engaging elements are formed from individual outwardly bent cantilevered tabs of the tube structure, and
wherein the component engaging elements are formed between the first end and the second end.

2. The bolt retainer of claim 1 , wherein the inwardly bent cantilevered tabs are individually paired with corresponding ones of the outwardly bent cantilevered tabs at a plurality of retention positions of the tube structure.

3. The bolt retainer of claim 2 , wherein the plurality of retention positions include individual openings formed between the inwardly bent cantilevered tabs and the outwardly bent cantilevered tabs.

4. The bolt retainer of claim 1 , wherein the bolt engaging elements are individually paired with corresponding ones of the component engaging elements at a plurality of retention positions that are around a circumference of the tube structure.

5. The bolt retainer of claim 1 , wherein the tube structure comprises spring steel, and
wherein the tube structure is shaped to permit the tube structure to be press-fit over a shoulder of the bolt.

6. The bolt retainer of claim 1 , wherein the seam is parallel to a longitudinal axis of the tube structure.

7. The bolt retainer of claim 1 , wherein the bolt retainer further comprises guiding elements,
wherein the guiding elements are formed on the second end of the tube structure, and
wherein the guiding elements are configured to retract inwardly to engage with the bolt.

8. A bolt retainer comprising:
a tube structure including a first end and a second end opposite the first end,
wherein the tube structure includes a seam between seam ends of a sheet that forms the tube structure, and
wherein the seam includes an interlocking component that prevents at least one of:
separation of the seam ends, or
longitudinal movement of the seam ends in opposite directions;

bolt engaging elements that extend from an inner surface of the tube structure to engage with a bolt,
wherein the bolt is to be positioned within a component,
wherein the bolt engaging elements are formed between the first end and the second end, and
wherein the bolt engaging elements are formed from corresponding inward cantilevered indentations formed on the inner surface of the tube structure; and

component engaging elements that extend from an outer surface of the tube structure to engage with the component,
wherein the component engaging elements are formed between the first end and the second end, and
wherein the component engaging elements are formed from corresponding outward cantilevered indentations formed on the outer surface of the tube structure.

9. The bolt retainer of claim 8 , further comprising:
guiding elements that extend inwardly from a bolt tip-side end of the of the tube structure.

10. The bolt retainer of claim 8 , wherein the bolt comprises a plow bolt.

11. The bolt retainer of claim 8 , wherein the bolt engaging elements are formed from individual inwardly bent tabs of the tube structure,
wherein the component engaging elements are formed from individual outwardly bent cantilevered tabs of the tube structure, and
wherein the inwardly bent tabs are individually paired with corresponding ones of the outwardly bent cantilevered tabs at a plurality of retention positions of the tube structure.

12. The bolt retainer of claim 8 , wherein the tube structure comprises spring steel, and
wherein the tube structure is shaped to permit the tube structure to be press-fit over a shoulder of the bolt.
