Abstract

A force-distributing apparatus for a bicycle wheel spoke includes a force-distributing body having a free-end first surface and a second surface disposed at an opposite side of the first surface. The force-distributing body has a spoke-receiving opening that extends through the first surface. In one embodiment, the first surface substantially has the shape of a truncated sphere. In another embodiment, the force distributing body has a generally cylindrical shape. In another embodiment, the spoke-receiving opening is formed eccentrically in the force-distributing body.

First claim

What is claimed is:

1. A force distributing apparatus for a bicycle wheel spoke mounting element for a spoke having an elongated spoke body, wherein the spoke mounting element is enlarged relative to the spoke body for mounting the spoke to a hub flange of a bicycle wheel hub, wherein the apparatus comprises:
a force-distributing body having a free-end first surface and a second surface disposed at an opposite side of the first surface;
wherein the first surface has the shape of a truncated sphere;
wherein the entire second surface that contacts the spoke mounting element has the shape of a frustum of a sphere; and
wherein the force-distributing body has a spoke-receiving opening that extends through the first surface.

2. The apparatus according to claim 1 wherein the force-distributing body has the shape of a truncated sphere.

3. The apparatus according to claim 2 wherein the first surface has the shape of a frustum of a sphere.

4. The apparatus according to claim 2 wherein the force-distributing body has the shape of a frustum of a sphere.

5. The apparatus according to claim 2 wherein the second surface has a concave shape.

6. A force distributing apparatus for a bicycle wheel spoke mounting element for a spoke having an elongated spoke body, wherein the spoke mounting element is enlarged relative to the spoke body for mounting the spoke to a hub flange of a bicycle wheel hub, wherein the hub flange includes an opening with a flange-opening axis, and wherein the apparatus comprises:
a force-distributing body including:
a free-end first surface;
a second surface disposed at an opposite side of the first surface; and
a spoke-receiving opening;

wherein the first surface is structured to engage the hub flange when the spoke mounting element is mounted to the hub flange;
wherein the second surface is shaped to allow the spoke mounting element to move in any lateral direction relative to the force distributing body; and
wherein at least one of the first surface or the second surface is shaped to allow the spoke mounting element to move in any lateral direction relative to the flange-opening axis.

7. The apparatus according to claim 6 wherein the first surface is shaped to allow the spoke mounting element to move in any lateral direction relative to the flange-opening axis when the spoke mounting element is mounted to the hub flange.

8. The apparatus according to claim 6 wherein the second surface is shaped to allow the spoke mounting element to move in any lateral direction relative to the flange-opening axis when the spoke mounting element is mounted to the hub flange.

9. The apparatus according to claim 6 wherein the first surface has the shape of a truncated sphere.

10. The apparatus according to claim 9 wherein the force-distributing body has the shape of a frustum of a sphere.

11. The apparatus according to claim 9 wherein the second surface has a concave shape.

12. The apparatus according to claim 11 wherein the second surface has the shape of a frustum of a sphere.

13. The apparatus according to claim 9 wherein the first surface has the shape of a frustum of a sphere.

14. The apparatus according to claim 6 wherein the entire second surface that contacts the spoke mounting element has the shape of a frustum of a sphere.

15. The apparatus according to claim 6 wherein the second surface has a concave shape, and wherein the entire second surface has the shape of a frustum of a sphere.
