Abstract

Provided is a paint roller which includes a handle connected to one end of a wire frame and a cage connected to an opposite end of the wire frame onto which a paint roller cover may be positioned and engaged over. The handle may include an insert or adapter allowing for connecting various types of extension poles. The cage may be connected through the wire frame through the use of bearings and bushings.

First claim

What is claimed is:

1. A paint roller comprising:
a wire frame having a first end and a second end, wherein the first end of the wire frame extends from a first longitudinal portion to a first bend, which extends to a first horizontal portion, which extends to a second bend, which extends to a second longitudinal portion, which extends to a third bend, which extends to a second horizontal portion at the second end of the wire frame;
a handle having a first end and a second end wherein the first end of the handle is engaged to the first end of the wire frame;
a first aperture and a second aperture positioned at a first end and a second end of the second horizontal portion at the second end of the wire frame;
a first bearing having a first internal chamber which is aligned with the first aperture of the wire frame and a second internal chamber substantially perpendicular to the first internal chamber which receives a portion of the wire frame;
a second bearing having a first internal chamber which is aligned with the second aperture of the wire frame and a second internal chamber substantially perpendicular to the first internal chamber which receives a portion of the wire frame;
a first pin inserted through the first internal chamber of the first bearing and the first aperture on the wire frame;
a second pin inserted through the first internal chamber of the second bearing and the second aperture on the wire frame;
a first bushing having a substantially cylindrical body having an outer wall and an inner wall defining an internal chamber, a closed end and an open end, wherein the first bushing includes an aperture within the closed end that allows it to be positioned at the first end of the second horizontal portion at the second end of the wire frame;
a second bushing having a substantially cylindrical body having an outer wall and an inner wall defining an internal chamber a closed end and an open end, wherein the second bushing is positioned at the second end of the second horizontal portion at the second end of the wire frame; and
a roller having a first end and a second end, wherein the roller is engaged to the second horizontal portion at the second end of the wire frame through the first and second bearing and the first and second bushing.

2. The paint roller of claim 1 , wherein the roller is shape of a cylindrical piece having a first end, a second end and a cylindrically consistent smooth surface, wherein the roller has a radially expanded portion at its first end and a radially expanded portion at its second end relative to its interior portion and wherein the first and second ends of the roller respectively engage a first and second bushing.

3. The paint roller of claim 1 , wherein the roller is a cage having at least two lateral elements and at least two circular elements substantially perpendicular to the lateral elements, wherein one circular element is positioned at the first end and one circular element is positioned at the second end of the cage, a first rim adjacent to the circular element at the first end of the cage, and a second rim adjacent to the circular element at the second end of the cage.

4. The paint roller of claim 3 , wherein the cage comprises four lateral elements and six circular elements substantially perpendicular to the lateral elements wherein one circular element is positioned at the first end of the cage and one circular element is positioned at the second end of the cage, wherein the lateral elements are spaced at equidistant points relative to each other along the cage and wherein the circular elements are spaced at equidistant points relative to each other along the cage.

5. The paint roller of claim 4 , wherein the rim at the first end of the cage includes a recess along the circumference of the rim which allows for the first end of the cage to engage an internal protrusion along the inner wall of the first bushing and wherein the rim at the second end of the cage includes a recess along the circumference of the rim which allows for the second end of the cage to engage an internal protrusion along the inner wall of the second bushing.

6. The paint roller of claim 5 , wherein a first circular element at the first end of the cage and a second circular element at the second end of the cage has an increased diameter relative to the circular elements positioned internally along the body of the cage and wherein the lateral elements are tapered outwardly at the first and second ends of the cage to connect to the first circular element at the first end of the cage and the second circular element at the second end of the cage.

7. The paint roller of claim 6 , wherein the outer wall of the cylindrical body of the first bushing comprises external ribs spaced at various points along the outer wall.

8. The paint roller of claim 7 , wherein the closed end of the first bushing comprises a cylindrical cover having a diameter that is greater than the diameter of the cylindrical body of the first bushing so that the cylindrical cover forms a substantially circular rim over the cylindrical body and wherein the external ribs on the cylindrical body of the first bushing extend short of the cylindrical cover forming a gap between the circular rim and the external ribs.

9. The paint roller of claim 1 , wherein the handle comprises a first projecting edge and a second projecting edge both of which are positioned at the first end of the handle.

10. The paint roller of claim 9 , wherein the second end of the handle is engaged to an insert comprising an insert body having an interior chamber, a first end and a second end; wherein the first end of the insert is engaged to the handle and the second end of the insert functions as an adapter designed to engage an extension pole system.

11. The paint roller of claim 10 , wherein the insert comprises an insert flange having a top portion and a bottom portion, wherein the top portion of the insert flange comprises at least one U-shaped recess and the bottom portion of the insert flange comprises concave features.

12. The paint roller of claim 11 , wherein the U -shaped recess on the top portion of the insert flange form holes into which an actuator pin of an extension pole system may engage and wherein the concave features on the bottom portion of the insert flange are designed to prevent relative rotation of the extension pole system with the insert when the extension pole system is engaged to the insert.

13. The paint roller of claim 12 , wherein the insert includes two areas of insert ribs that extend axially on the top and bottom of the interior of the insert and two areas of smooth surfaces that extend axially on the interior sides of the insert which are designed to engage an extension pole system.

14. The paint roller of claim 1 , wherein the first bearing and the second bearing comprise a shoulder portion adjacent to the cylindrical portion of the second internal chamber.

15. The paint roller of claim 14 , wherein the internal chamber of the first and second bushing includes at least two spokes extending from a centrally positioned hub.

16. The paint roller of claim 15 , wherein the hub of the first and second bushing comprises a substantially cylindrical frame having a hollow interior.

17. The paint roller of claim 16 , wherein the hub of the first bushing is capable of receiving the cylindrical portion of the second internal chamber of the first bearing and wherein the hub of the second bushing is capable of receiving the cylindrical portion of the second internal chamber of the second bearing.
