Abstract

An adjustable rim includes a first annular ring rotatable about a first axis, the first ring having radially extending first linear slots circumferentially spaced about the first ring, a first annular adjustment hoop rotatable about the first axis, the first hoop having circumferentially and radially extending first arcuate slots spaced about the first hoop, a second annular ring rotatable about a second axis, the second ring having radially extending second linear slots circumferentially spaced about the second ring, a second annular adjustment hoop rotatable about the second axis, the second hoop having circumferentially and radially extending second arcuate slots spaced about the second hoop, and an axially extending arcuate member having a first axial end and a second axial end. The first axial end is circumferentially and radially aligned with a first linear slot of the first annular ring and a first arcuate slot of the first annular hoop. The first linear slot and the first arcuate slot interact to move part of the arcuate member in only a radial direction.

First claim

What is claimed:

1. An adjustable rim comprising:
a first annular ring rotatable about a first axis, the first annular ring having radially extending first linear slots circumferentially spaced about the annular first ring;
a first annular adjustment hoop rotatable about the first axis, the first annular hoop having circumferentially and radially extending first arcuate slots spaced about the first annular hoop;
a second annular ring rotatable about a second axis, the second annular ring having radially extending second linear slots circumferentially spaced about the second annular ring;
a second annular adjustment hoop rotatable about the second axis, the second annular hoop having circumferentially and radially extending second arcuate slots spaced about the second annular hoop; and
an axially extending arcuate member having a first axial end and a second axial end, the first axial end being circumferentially and radially aligned with a first linear slot of the first annular ring and a first arcuate slot of the first annular hoop, the first linear slot and the first arcuate slot interacting to move part of the arcuate member in only a radial direction.

2. The adjustable rim as set forth in claim 1 wherein the second axial end is circumferentially and radially aligned with a second linear slot of the second annular ring and a second arcuate slot of the second annular hoop, the second slot and the second arcuate slot interacting to move part of the arcuate member in only a radial direction.

3. The adjustable rim as set forth in claim 2 wherein rotation of the first annular hoop relative to the first annular ring about the first axis moves the first axial end of the arcuate member.

4. The adjustable rim as set forth in claim 3 wherein rotation of the second annular hoop relative to the second annular ring about the second axis moves the second axial end of the arcuate member.

5. The adjustable rim as set forth in claim 4 wherein the first axis and the second axis are coincident.

6. The adjustable rim as set forth in claim 1 wherein the arcuate member engages a spoke structure and radial movement of the arcuate member alters an amount of radial tension placed on the spoke structure.

7. The adjustable rim as set forth in claim 1 further including a support member attached to the first annular ring, the support member having a cylindrical hub and radially protruding extensions projecting radially outward from the cylindrical hub.

8. The adjustable rim as set forth in claim 1 wherein the arcuate member has an axial bore extending through the arcuate member.

9. The adjustable rim as set forth in claim 8 further including a shaft bolt axially inserted through the first annular ring, the first annular hoop, the axial bore of the arcuate member, the second annular ring, and the second annular hoop.

10. The adjustable rim as set forth in claim 9 further including a fastener nut fixed to the shaft bolt thereby axially securing the first annular ring, the first annular hoop, the arcuate member, the second annular ring, and the second annular hoop.
