Abstract
Embodiments of a paint roller support for rotatably supporting a conventional paint roller cover are disclosed. In one embodiment, a paint roller support comprises a frame having an elongated shaft and at least one hub rotatably coupled to the shaft for supporting a conventional roller cover. A locking spring exerts a retaining force against an inner surface of the roller cover for frictionally retaining the roller cover on the hub while the paint roller support is used to deliver paint to a surface. Embodiments of a method for manufacturing a paint roller support also are disclosed.

- a paint roller cover for placing on the roller cover support;
- and
- wherein:
- the shaft has an outboard end;
- and
- the bearing is formed with an axial opening for receiving the shaft and a closed end wall positioned adjacent the outboard end of the shaft.
A paint roller comprising:
- an elongated shaft, the shaft having a raised surface portion;
- at least one bearing frictionally engaging the raised surface portion, the bearing being fixed against rotational movement relative to the shaft;
- a roller cover support supported on the bearing for rotational movement relative thereto, the roller cover support defining a bearing receiving space substantially enclosing the bearing and configured to prevent removal of the roller cover support from the bearing in the inboard and outboard directions, wherein the roller cover support comprises first and second interconnected hub portions defining the bearing receiving space, the first hub portion having an inner surface juxtaposed to a first radial bearing surface of the bearing and the second hub portion having an inner surface juxtaposed to a second radial bearing surface of the bearing;
- a paint roller cover for placing on the roller cover support;
- and
- a cover-gripping element disposed in an annular space defined between the first and second hub portions, the cover-gripping element configured to frictionally retain the roller cover on the cover support.
A paint roller support for supporting a roller cover, comprising:
- an elongated shaft;
- and
- a roller-cover grabbing mechanism rotatably coupled to the shaft, the grabbing mechanism comprising a non-circular split ring configured to contact an inside surface of the roller cover at a plurality of angularly spaced locations, the ring exerting a retaining force against the inside surface of the roller cover at the angularly spaced locations, thereby retaining the roller cover on the shaft.
A paint roller support for supporting a roller cover, comprising:
