Skirt for toner cartridge

1. A skirt for attachment to a shaft of a toner cartridge paddle, comprising:

a body having an upper edge, a continuous lower edge and two side edges with the upper edge and lower edge being parallel to one another;

a plurality of spaced apart tapered beams extending along said body between the upper and lower edges and attached to the upper and lower edges of the body;

each of the tapered beams having a first end dimension B adjacent the upper edge and a second end dimension b adjacent the lower edge;

each of the plurality of beams having tapered edges between the first end and the second end defining a ratio R defined by dimensions b/B being from about 0 to 0.9 for inhibiting creep deflection; and

a plurality of spaced apart mounting apertures extending along the upper edge of the body for mounting the body to the shaft of the toner paddle.

2. The skirt of claim 1 wherein at least one of the plurality of mounting apertures is disposed between each of the tapered beams.

3. The skirt of claim 1 wherein said body has a thickness of about 0.1 millimeter.

4. The skirt of claim 1 wherein said body has a thickness of about 0.2 millimeters.

5. The skirt of claim 1 wherein said body is formed of polyethylene terephthalate polyester (PET).

6. The skirt of claim 1 wherein said ratio R is about 0.27.

7. A paddle assembly for urging toner to a location within a toner cartridge, comprising:

a rotatable shaft having a plurality of fasteners extending therefrom;

a skirt having a plurality of sides including an upper skirt edge and a continuous lower skirt edge and a plurality of mounting apertures therethrough and extending along said upper skirt edge for receiving corresponding ones of the plurality of fasteners for attaching said skirt to said shaft;

a plurality of spaced apart tapered beams extending between said upper skirt edge and said lower skirt edge and attached to said upper and lower skirt edges;

said tapered beams having a base portion adjacent said upper skirt edge with a dimension B and a tip portion adjacent said lower skirt edge with a dimension b; and

said tapered beams being tapered from said tip portion to said base portion defining a ratio R of b to B of less than or equal to about 0.9 for inhibiting creep deflection.

8. The paddle assembly of claim 7 wherein said beams are tapered with said ratio R being about 0.27.

9. The paddle assembly of claim 7 wherein said beams have a wider dimension at an upper area and a narrower dimension at a lower area.

10. The paddle assembly of claim 7 wherein said lower skirt edge is an interference edge for engaging an inner surface of the toner cartridge.

11. The paddle assembly of claim 7 , said skirt further comprising a thickness of about 0.125 millimeters.

12. The paddle assembly of claim 7 , said skirt further comprising a thickness of about 0.188 millimeters.

13. The paddle assembly of claim 7 , wherein said skirt has a thickness of between about 0.1 and 0.2 millimeters.

14. An attachable skirt for a toner paddle, comprising:

a flexible body having an upper edge and a continuous lower edge, the upper and lower edges being parallel, the body have a plurality of mounting apertures extending along and adjacent to the upper edge;

a plurality of windows within said body disposed between said upper edge and said lower edge of said body;

said plurality of windows defined by a plurality of tapered beams connected between said upper and lower edges of said body;

each of said plurality of tapered beams having a wider end having a dimension B near said upper edge and a narrower end having a dimension b near said lower edge; and

each of said plurality of tapered beams being tapered having a ratio R of b/B of between about 0 to 0.9 to inhibit creep deflection.
