Roller cover support consists of blow molded sleeve having plural protruding ribs to frictionally retain the roller cover in place. The ends of the sleeve are molded to receive and mount end caps thereon which include suitable bearings for the roller frame shaft and provide some support against collapse or flattening out of the sleeve during use under pressure. The O.D. of the end caps and adjacent ends of the sleeve are slightly smaller than the I.D. of the roller cover for normal concentricity and guidance of the roller cover onto the sleeve, and the ends of the ribs are tapered to wedge the roller cover on. When the roller frame shaft extends all the way through the roller support, perforations may be placed along the length of the sleeve to provide for drainage of any water or other liquid that may seep into the interior of the sleeve through the end cap bearings during clean up. However, a Y-shape frame may be used having spaced apart end supports for both ends of the sleeve, so that the end caps may be completely closed to keep water out. Such end supports are preferably substantially flat and parallel to each other and relatively thin so as not to interfere with painting closely adjacent to a corner and the like.
A roller cover support for a paint roller frame comprising a plastic molded sleeve having a plurality of protruding ribs thereon for frictionally retaining a roller cover on said sleeve, and separately formed end caps secured to the ends of said sleeve, said end caps having bearings for journaling of said roller cover support on said paint roller frame, said sleeve, including said ribs, being blow molded as a single piece from a high density plastic material having high impact resistance and controlled flexibility for firmly gripping the roller cover and controlling the amount of pull off required to remove the roller cover from said support for ease of cleaning and replacement, the ends of said ribs being tapered to wedge the roller cover on said sleeve, there being two separate sets of said ribs, one of said sets being located adjacent each end of said sleeve.
A roller cover support for a paint roller frame comprising a plastic molded sleeve having a plurality of protruding ribs thereon for frictionally retaining a roller cover on said sleeve, and separately formed end caps secured to the ends of said sleeve, said end caps having bearings for journaling of said roller cover support on said paint roller frame, said sleeve, including said ribs, being blow molded as a single piece from a high density plastic material having high impact resistance and controlled flexibility for firmly gripping the roller cover and controlling the amount of pull off required to remove the roller cover from said support for ease of cleaning and replacement, the ends of said ribs being tapered to wedge the roller cover on said sleeve, said end caps being injection molded to form said bearings for rotatably mounting said roller cover support on the shaft portion of said paint roller frame and support said sleeve against collapse or flattening out during use under pressure, said paint roller frame including a shaft portion adapted to extend completely through said sleeve, and said bearings have openings completely therethrough for said shaft portion, said roller cover support being retained on said shaft portion by a snap-on cap on the outboard end of said shaft portion, and a closure member inserted into the center of the outboard end cap to cover said snap-on cap and outboard end of said shaft portion so as to prevent paint from accumulating therein.
A roller cover support for a paint roller frame comprising a plastic molded sleeve having a plurality of protruding ribs thereon for frictionally retaining a roller cover on said sleeve, and separately formed end caps secured to the ends of said sleeve, said end caps having bearings for journaling of said roller cover support on said paint roller frame, said sleeve, including said ribs, being blow molded as a single piece from a high density plastic material having high impact resistance and controlled flexibility for firmly gripping the roller cover and controlling the amount of pull off required to remove the roller cover from said support for ease of cleaning and replacement, the ends of said ribs being tapered to wedge the roller cover on said sleeve, and perforations in such sleeve to provide for drainage of water or solvent which may enter the interior of said sleeve during cleaning.
A roller cover support for a paint roller frame comprising a plastic molded sleeve having a plurality of protruding ribs thereon for frictionally retaining a roller cover on said sleeve, and separately formed end caps secured to the ends of said sleeve, said end caps having bearings for journaling of said roller cover support on said paint roller frame, said sleeve, including said ribs, being blow molded as a single piece from a high density plastic material having high impact resistance and controlled flexibility for firmly gripping the roller cover and controlling the amount of pull off required to remove the roller cover from said support for ease of cleaning and replacement, the ends of said ribs being tapered to wedge the roller cover on said sleeve, said end caps being injection molded to form said bearings for rotatably mounting said roller cover support on the shaft portion of said paint roller frame and support said sleeve against collapse or flattening out during use under pressure, said ends of said sleeve having integrally blow molded protrusions thereon of reduced diameter, with central openings in said protrusions for receipt of said bearings on said end caps, said end caps having annular hub portions surrounding said bearings which extend over said reduced diameter protrusions on said sleeve ends, said hub portions contacting said sleeve ends and being of the same O.D. as said sleeve ends adjacent said protrusions.
A roller cover support for a paint roller frame comprising a single piece plastic molded sleeve having two separate sets of longitudinally extending protruding ribs thereon, one of said sets being located adjacent each end of said sleeve, each said set comprising a plurality of said ribs for frictionally retaining a roller cover on said sleeve, the ends of said ribs being tapered for a substantial extent to wedge the roller cover on said sleeve, and separately formed end caps secured to the ends of said sleeve, said end caps having bearings for journaling of said roller cover support on said paint roller frame.
