Abstract

A paint roller assembly includes a wire frame having a spindle on which a wire cage is rotatably mounted with end mounting bearing members. An outermost bearing member includes an annular wall provided with a flexible arm having a stop at its distal end. The stop normally abuts an end of a tubular paint roller to lock same against lengthwise movement. A paint barrier on the bearing member defines an area for momentary reception of the arm and stop during roller removal and installation procedures.

Claims

1. A frame for supporting a replaceable paint roller, comprising a handle attached to a rod having first and second bearings thereon for receiving and supporting the paint roller, the first bearing being located proximate a terminal end of the rod, the first bearing having an annular wall and an end wall substantially abutting an outer end of the annular wall, and a retainer connected to one of the walls of the first bearing, the retainer including a manually actuated stop such that when the stop is in its normal unactuated condition the stop inhibits axially outward movement of a paint roller mounted on the bearings and such that when the stop is manually actuated a paint roller can be inserted axially onto the bearings or removed axially therefrom while the end wall is coupled to the annular wall.

2. The frame of claim 1 wherein the stop is located proximate the end wall.

3. The frame of claim 1 wherein the end wall is substantially planar and the stop includes a distal surface and a proximal surface and the proximal surface is substantially coplanar with the end wall.

4. The frame of claim 1 wherein the end wall is substantially planar and the stop includes a distal surface and a proximal surface and the distal surface is substantially coplanar with the end wall.

5. The frame of claim 1 wherein the end wall is non-concave.

6. The frame of claim 1 further comprising a wire cage having a plurality of wire spokes that are supported by, and extend between the first and second bearings and wherein the wire cage assists to support the paint roller.

7. The frame of claim 1 wherein the retainer comprises an arm resiliently coupled to the annular wall and extending toward the end wall, the arm terminating at the stop.

8. The frame of claim 1 wherein the retainer comprises an elongate arm resiliently coupled to the annular wall, the arm terminating at the stop, wherein the stop is upturned from the arm and substantially orthogonal to the arm.

9. The frame of claim 1 wherein the wall and the end wall define a recess and the retainer is located substantially within the recess.

10. The frame of claim 1 wherein the annular wall and the end wall define a recess having tapered side walls and a bottom wall and the retainer is located in the recess between the side walls.

11. The frame of claim 1 wherein the annular wall defines an elongate recess having a triangular longitudinal cross section and a U-shaped transverse cross section and the retainer is located within the recess.

12. The frame of claim 1 wherein the annular wall and end wall define a recess comprising a bottom wall that intersects the annular wall and the end wall, the bottom wall being bounded by side walls so that the end wall, bottom wall, and side walls form a liquid barrier to block a liquid when a paint roller is mounted onto the frame thereby defining an interior chamber wherein it is desirable to prevent liquid from entering the chamber.

13. The frame of claim 1 further comprising a wire cage having a plurality of wire spokes that are supported by the first and second bearings and wherein the first bearing includes receptacles for receiving spokes of the wire cage and the annular wall defines a recess that is located between the receptacles and the retainer is located in the recess.

14. A frame for a paint roller, the frame including a handle coupled to a rod, first and second bearings located on the rod, the first and second bearings located in spaced apart relationship to support a paint roller, characterized by the first bearing having an annular side wall having a width, an end wall fixedly coupled to the side wall, a retainer for retaining a paint roller on the frame during operation of the paint roller, the retainer including an arm that is resiliently coupled to the side wall and including a stop coupled to the arm and located proximate the end wall.

15. The frame of claim 14 wherein the end wall is substantially planar and the stop includes a surface that is substantially coplanar with the end wall.

16. The frame of claim 14 wherein the retainer arm is substantially coplanar with the annular side wall.

17. The frame of claim 14 wherein the arm has a length that is less than the width of the side wall.

18. The frame of claim 14 wherein the retainer deflects during installation and deinstallation of a paint roller onto the frame and when the paint roller is installed onto the frame the retainer is biased into a position substantially flush with the annular side wall and thereby retains the paint roller on the frame.

19. The frame of claim 14 wherein the side wall and the end wall define a recess for receiving the retaining when the retainer is deflected during installation and deinstallation of a paint roller onto the frame.

20. The frame of claim 14 wherein the side wall and the end wall define a recess for receiving the retainer when the retainer is deflected, wherein the recess includes a bottom wall that extends obliquely between the side wall and the end wall and tapered sides that extend between the bottom wall and the side wall thereby forming a wedge shaped recess and the retainer is located substantially within the recess.

21. The frame of claim 14 wherein the side wall and the end wall define a recess having a bottom wall that extends obliquely between the side wall and the end wall thereby forming a junction at the bottom wall and the side wall and wherein the retainer arm is coupled to the side wall proximate the junction.

22. The frame of claim 14 wherein the side wall and the end wall define a recess having boundary surfaces, and the side wall, end wall and recess surfaces create a barrier to block liquid so that when a paint roller is installed onto the frame, thereby creating a chamber bounded by the paint roller and the first and second bearings, the barrier blocks liquid from entering the chamber.

23. The frame of claim 14 wherein the side wall and end wall are coupled at a substantially circular edge and the side wall and end wall define a recess having a bottom wall that extends between, and obliquely intersects, the side wall and end wall, the bottom wall intersecting the end wall at a first distance from the edge, wherein the retainer is located in the recess and resiliently coupled to the side wall proximate the intersection of the side wall and the bottom wall, and wherein the retainer stop has a height that is substantially equal to the first distance.
