Abstract

A cage for a roller cover includes a plurality of hubs, a longitudinal support member interconnecting a plurality of hubs and a roller cover support surface integrally formed with the hubs and the support member. The roller cover support surface is resiliently biased outwardly beyond at least one of the hubs for resiliently engaging the roller cover.

Claims

1. A cage for a roller cover, the cage comprising:

a plurality of hubs including a distal hub centered about an axis and a proximal hub centered about the axis; and

at least three circumferentially spaced longitudinally extending roller cover support surfaces integrally formed with the hubs and extending outwardly beyond at least one of the hubs, a first and a second of the roller cover support surfaces extending in a plane spaced from said axis and the third roller cover support surface further extending from the plane intermediate the first and second roller cover support surfaces, wherein the third roller cover support surface is resiliently biased outwardly beyond the at least one of the hubs for resiliently engaging the roller cover.

2. The cage of claim 1 wherein the third roller cover support surface radially flexes.

3. The cage of claim 2 including:

a longitudinal bridge extending between adjacent hubs and supporting the flexing surface, wherein the bridge flexes to radially flex the flexing surface.

4. The cage of claim 3 wherein the longitudinal bridge has first and second opposite edges providing the first and the second roller cover supporting surfaces, respectively.

5. The cage of claim 1 including at least one transversely extending roller cover support surface resiliently biased beyond at least one of the hubs to longitudinally flex when engaging the roller cover.

6. The cage of claim 1 wherein said at least one of said roller cover support surfaces extend along a projection extending from at least one of the plurality of hubs.

7. The cage of claim 1 wherein the third roller cover support surface has a reduced height adjacent at least one of the plurality of hubs.

8. The cage of claim 1 wherein at least one of the roller cover support surfaces is inflexible in a radial direction.

9. A cage for a roller cover, the cage comprising:

first and second hubs centered about an axis;

a first bridge spanning the first and second hubs along the axis, the first bridge being resiliently deformable towards the axis, wherein the first bridge has first and second opposite edges providing first and second roller cover supporting surfaces configured to engage the roller cover; and

a first longitudinal support member longitudinally extending along the first bridge non-parallel from the first bridge to provide a third roller cover support surface beyond at least one of the first and second hubs, wherein the first bridge resiliently biases the third roller cover support surface into engagement with the roller cover.

10. The cage of claim 9 including:

a second bridge spanning the first and second hubs, the second bridge being resiliently deformable towards the axis, wherein the second bridge has third and fourth opposite edges providing fourth and fifth roller cover supporting surfaces configured to engage the roller cover; and

a second longitudinal support member extending along the second bridge non-parallel from the second bridge to provide a sixth roller cover support surface beyond at least one of the first and second hubs, wherein the second bridge resiliently biases the sixth roller cover support surface into engagement with the roller cover.

11. The cage of claim 10 wherein the second bridge extends diametrically opposite the first bridge and wherein the sixth roller cover support surface extends diametrically opposite the third roller cover support surface.

12. The cage of claim 9 wherein the third roller cover support surface has a reduced height adjacent the first hub.

13. The cage of claim 12 wherein the third roller cover support surface has a reduced height adjacent the second hub.

14. The cage of claim 9 wherein the first hub includes two longitudinally offset and adjacent half-hubs.

15. A cage for a roller cover, the cage comprising:

a plurality of hubs including a first hub centered about an axis and a second hub centered about the axis;

a first bridge spaced from said axis and spanning the first and second hubs, the first bridge including first and second opposite edges providing first and second roller cover support surfaces spaced from the axis, and configured to engage the roller cover;

a first longitudinal support member longitudinally extending along the first bridge non-parallel to the first bridge to provide a third roller cover support surface configured to engage the roller cover;

a second bridge spaced from said axis and spanning the first and second hubs, the second bridge having third and fourth opposite edges providing fourth and fifth roller cover supporting surfaces configured to engage the roller cover; and

a second longitudinal support member longitudinally extending along the second bridge non-parallel to the second bridge to provide a sixth roller cover support surface configured to engage the roller cover, wherein the first and second bridges resiliently bias the third and sixth roller cover support surfaces into engagement with the roller cover.

16. The cage of claim 15 including at least one transversely extending roller cover support surface resiliently biased beyond at least one of the hubs to longitudinally flex when engaging the roller cover.
