Abstract

A roller cage assembly provides a support for a roller sleeve and consisting of a primary and secondary hub. The inner surface of the primary hub and the inner surface of the secondary hub provides a compression fitting so that a longitudinal tube pressed into the compression fitting on the primary inner hub and pressed into the compression fitting on the secondary inner hub joins primary inner hub to secondary inner hub by the longitudinal tube and results in one complete unit. The circumference of the outer primary hub and the circumference of the secondary outer hub is encircled by the rubber or formed plastic o-ring providing a seal to prevent liquids from entering the inner cavity of the roller cage assembly. Each cage hub assembly encloses the roller sleeve into a fixed and immovable position.

Claims

1. A roller cage assembly for use with a paint roller handle having a rod, the assembly comprising:

a roller sleeve having a first end and a second end;

a primary and a secondary hub, each hub having an outer portion and an inner portion, the outer portion having a larger diameter than the inner portion and adapted to engage the inner surface of the roller sleeve;

a tube connected between the primary hub inner portion and the secondary hub inner portion;

each of the hubs further including;

an annular tube stop adjacent to but spaced from the free end of the inner portion of the respective hub to define a region within the respective inner portion adapted to frictionally engage the tube interconnecting the hubs, the ends of the tube frictionally engaging an inner surface of the respective hub inner portion, the tube stop and a wall of the respective outer hub portion further defining a cavity, each cavity housing a keeper having a keeper gap allowing expansion of the keeper during intercourse with the rod while facilitating a tight grip between the keeper and the rod, each of the keepers having a size such that they allow free rotational movement of the associated hub thereabout, and

wherein the roller sleeve, the primary hub, the secondary hub and the tube are arranged to define a sealed inner cavity, whereby liquid into the cavity is reduced.

2. The roller cage assembly of claim 1, wherein liquid transfer into the inner cavity is prevented.

3. The roller cage assembly of claim 1, wherein the primary hub, the primary keeper, the tube, the secondary keeper, and the secondary hub are adapted to receive the rod.

4. The roller cage assembly of claim 1, wherein the primary hub and the secondary hub are exactly similar.

5. The roller cage assembly of claim 1, wherein the primary hub further comprises a flange for engaging the first end of the roller sleeve, and the secondary hub further comprises a flange for engaging the second end of the roller sleeve.

6. The roller cage assembly of claim 1, wherein each keeper includes at least one keeper lip to minimize friction between the keeper and the respective hub cavity.

7. The roller cage assembly of claim 6, wherein each keeper includes two keeper lips.
