Abstract

A runner assembly includes a runner with an aperture, a cradle, and a fastener. The cradle includes a planar base with an aperture, a tab extending from the base, and fingers extending from the base. The fastener extends through the apertures for attaching the runner to the cradle, and the fingers are adjacent to the runner and constrain the runner with respect to the cradle and the fastener.

First claim

The invention claimed is:

1. A runner assembly comprising:
a runner including a first fastener aperture;
a cradle comprising:
a substantially planar base including a second fastener aperture, the base comprising a stiffening bead;
a first tab extending from the base configured for mounting the runner assembly to an article; and
a plurality of fingers extending from the base; and
a first fastener extending through the first and second fastener apertures for attaching the runner to the cradle;
wherein the plurality of fingers are adjacent to the runner and constrain the runner with respect to the cradle and the first fastener.

2. The runner assembly of claim 1 , wherein the first tab includes a tab aperture, and further comprises:
a second fastener extending through the tab aperture for attaching the runner assembly to the article.

3. The runner assembly of claim 1 , and further comprising:
a second tab extending from the base opposite of the first tab, the second tab configured for attaching the runner assembly to the article.

4. The runner assembly of claim 3 , wherein the first and second tabs are each substantially planar.

5. The runner assembly of claim 1 , wherein the runner includes a cradle side that is adjacent to the base of the cradle, the cradle side being substantially planar.

6. The runner assembly of claim 1 , wherein the runner includes a mounting portion and the plurality of fingers extend around the mounting position.

7. The runner assembly of claim 1 , and further comprising:
a lightening cut in the base.

8. A runner assembly comprising:
a cradle comprising:
a substantially planar base having a ring side, a runner side, a first end, and a second end, the base including a first fastener aperture extending through the base;
a first tab extending from the first end, the first tab including a first tab aperture;
a second tab extending from the second end, the second tab including a second tab aperture;
a first finger that extends from the first end;
a second finger that extends from the second end;
a first bend at a junction of the first tab and the base; and
a second bend at a junction of the second tab and the base;
wherein the first and second tabs extend toward the runner side of the base; and

a runner comprising:
a mounting portion positioned between the first and second fingers and the base of the cradle, including a substantially planar cradle side that contacts the runner side of the base;
a contact portion with a curved contact side that is opposite of the cradle side; and
a second fastener aperture extending through the mounting portion and the contact portion; and
a first fastener extending through the first and second fastener apertures, the fastener attaching the runner to the cradle.

9. The runner assembly of claim 8 , wherein the base of the cradle includes a stiffening bead.

10. The runner assembly of claim 8 , wherein the first and second fingers are curved.

11. The runner assembly of claim 8 , wherein the base of the cradle includes a lightening cut.

12. The runner assembly of claim 8 , wherein the cradle is comprised of sheet metal.

13. The runner assembly of claim 8 , wherein the runner is comprised of a composite material.

14. The runner assembly of claim 13 , wherein the runner comprises a composite material including fibers.

15. The runner assembly of claim 8 , wherein the contact portion of the runner extends beyond the first and second fingers.

16. The runner assembly of claim 8 , wherein the cradle includes a third fastener aperture and the runner includes a fourth fastener aperture, and further comprising:
a second fastener that extends through the third and fourth fastener apertures.

17. The runner assembly of claim 8 , wherein the cradle further comprises:
a third finger that extends from the first end and is curved; and
a fourth finger that extends from the second end and is curved.

18. The runner assembly of claim 8 , wherein a length of the contact portion of the runner between the first and second fingers is shorter than a length of the mounting portion between the first and second fingers.

19. A runner assembly comprising:
a cradle comprising:
a substantially planar base having a ring side, a runner side, a first end, and a second end, the base including a first fastener aperture extending through the base;
a first tab extending from the first end, the first tab including a first tab aperture;
a second tab extending from the second end, the second tab including a second tab aperture;
a first finger that extends from the first end; and
a second finger that extends from the second end; and

a runner comprising:
a mounting portion positioned between the first and second fingers and the base of the cradle, including a substantially planar cradle side that contacts the runner side of the base;
a contact portion with a curved contact side that is opposite of the cradle side; and
a second fastener aperture extending through the mounting portion and the contact portion; and
a first fastener extending through the first and second fastener apertures, the fastener attaching the runner to the cradle;
wherein the contact portion of the runner extends beyond the first and second fingers.

20. The runner assembly of claim 19 , and further comprising:
a first bend at a junction of the first tab and the base; and
a second bend at a junction of the second tab and the base;
wherein the first and second tabs extend toward the runner side of the base.
