Abstract

Abstract A unitary molded core structure, such as of plastic or the like, for use in a paint roller. The core structure is rotatably mounted on an axle of the paint roller and receives a cylindrical paint applying sleeve. The core has a pair of parallel plates equally spaced from the axle along with supporting ribs therealong, with the edges of the plates and ribs rigidly supporting the paint applying sleeve in the planes thereof, but the plates having a degree of flexing to facilitate mounting various sleeves thereon. Journal defining webs are molded integrally with and extend between the parallel plates. Integrally molded end discs are provided at the ends of the plates, with a removable cap disposed on the one end disc at the free end of the axle.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 124 words
In a paint roller having a handle and an axle disposed at generally right angles with respect to the handle, a core structure rotatably mounted on said axle for axially receiving a cylindrical paint applying sleeve, said core structure being integrally molded and including a pair of generally parallel longitudinal plates spaced from, on opposite sides of and generally parallel to the axis of said axle, said plates being engageable along the edges thereof with the interior of said paint applying sleeve for rigidly supporting the sleeve generally in the planes of said plates but having flexibility at least at their edges generally in a direction transverse to said planes, and journal means between said plates for rotatably mounting the core on said axle.
Claim 2
Dependent Claim 124 words
In a paint roller having a handle and an axle disposed at generally right angles with respect to the handle, a core structure rotatably mounted on said axle for axially receiving a cylindrical paint applying sleeve, said core structure being integrally molded and including a pair of generally parallel longitudinal plates spaced from, on opposite sides of and generally parallel to the axis of said axle, said plates being engageable along the edges thereof with the interior of said paint applying sleeve for rigidly supporting the sleeve generally in the planes of said plates but having flexibility at least at their edges generally in a direction transverse to said planes, and journal means between said plates for rotatably mounting the core on said axle.
Claim 3
Dependent Claim 27 words
The paint roller of claim 1 wherein said journal means is formed on a plurality of longitudinally spaced webs extending between and molded integrally with said plates.
Claim 4
Dependent Claim 25 words
The paint roller of claim 1 including a longitudinal rib molded integrally with and protruding generally transversely of the plane of each of said plates.
Claim 5
Dependent Claim 51 words
The paint roller of claim 3 wherein said longitudinal ribs extend generally parallel to said axle and protrude generally radially outwardly therefrom and from said plates a distance sufficient to engage and provide rigid edge support for the interior of said paint applying sleeve generally in the planes of said ribs.
Claim 6
Dependent Claim 27 words
The paint roller of claim 3 wherein said journal means is formed on a plurality of longitudinally spaced webs extending between and molded integrally with said plates.
Claim 7
Dependent Claim 46 words
The paint roller of claim 1 including a pair of end discs molded integrally with and at the ends of said plates, said end discs having a diameter to provide peripheral circular support with the interior of said paint applying sleeve generally at the ends thereof.
Claim 8
Dependent Claim 44 words
The paint roller of claim 6 wherein the end disc at the free end of said axle is recessed to provide an interior area for accommodating appropriate securing means between the core and axle, and including a removable cap for covering said end recess.
Claim 9
Dependent Claim 30 words
The paint roller of claim 1 wherein said generally parallel plates are generally of the same width and are disposed in planes generally equidistant from the axis of said axle.
Claim 10
Dependent Claim 187 words
In a paint roller having a handle and an axle disposed at generally right angles with respect to the handle, a core structure rotatably mounted on said axle for axially receiving a cylindrical paint applying sleeve, said core structure being integrally molded and including a pair of generally parallel plates spaced equidistant from, on opposite sides of and generally parallel to the axis of said axle, said plates being of substantially the same width and engageable along the edges thereof with the interior of said paint applying sleeve for rigidly supporting the sleeve generally in the planes of said plates, a longitudinal rib molded integrally with each of said plates and protruding generally radially outwardly therefrom a distance sufficient to engage and provide rigid edge support for the interior of said paint applying sleeve, with said plates having flexibility at least at their edges generally about the juncture of the plates and ribs, and journal means between said plates for rotatably mounting the core on said axle, said journal means being formed on a plurality of longitudinally spaced webs extending bEtween and molded integrally with said plates.
Claim 11
Dependent Claim 187 words
In a paint roller having a handle and an axle disposed at generally right angles with respect to the handle, a core structure rotatably mounted on said axle for axially receiving a cylindrical paint applying sleeve, said core structure being integrally molded and including a pair of generally parallel plates spaced equidistant from, on opposite sides of and generally parallel to the axis of said axle, said plates being of substantially the same width and engageable along the edges thereof with the interior of said paint applying sleeve for rigidly supporting the sleeve generally in the planes of said plates, a longitudinal rib molded integrally with each of said plates and protruding generally radially outwardly therefrom a distance sufficient to engage and provide rigid edge support for the interior of said paint applying sleeve, with said plates having flexibility at least at their edges generally about the juncture of the plates and ribs, and journal means between said plates for rotatably mounting the core on said axle, said journal means being formed on a plurality of longitudinally spaced webs extending bEtween and molded integrally with said plates.
Claim 12
Dependent Claim 46 words
The paint roller of claim 9 including a pair of end discs molded integrally with and at the ends of said plates, said end discs having a diameter to provide peripheral circular support with the interior of said paint applying sleeve generally at the ends thereof.
Claim 13
Dependent Claim 44 words
The paint roller of claim 10 wherein the end disc at the free end of said axle is recessed to provide an interior area for accommodating appropriate securing means between the core and axle, and including a removable cap for covering said end recess.
