Definitions

  • 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. lntegrally 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.
  • This invention relates to paint rollers and. particularly. a new and improved core structure for rotatably mounting on the axle of a paint roller for receiving and rigidly supporting a cylindrical paint applying sleeve.
  • the principal objeet. therefore. of the present invention is to provide a new and improved core structure for a paint roller.
  • the core structure is rotatably mountable on the axle of a paint roller wherein the axle normally is disposed at generally right angles with respect to a handle.
  • the core structure axially receivesa cylindrical paint apply ing sleeve.
  • the core structure is integrally molded and includes a pair of substantially identical. generally parallel longitudinal plates spaced equidistant from. on opposite sides of and generally parallel to the axis of the roller axle.
  • a longitudinal rib is molded integrally with the plates and extend generally parallel to the axle.
  • the ribs protrude generally radially outwardly from the axle and the plates a distance sufficient to engage the interior of the paint applying sleeve whereby the longitudinal edges of the ribs and plates provide rigid support for the sleeve but the plates having sufficient flexibility to accommodate slight variances in the inside diameter of the sleeve.
  • Journals are formed on a plurality of longitudinally spaced webs extending between and molded integrally with the plates.
  • a pair of end discs are molded integrally with and at the ends of the plates. the end discs having diameters to provide peripheral circular support with the interior of the paint applying sleeve generally at the ends thereof.
  • An additional feature is providing a recess in the end disc disposed at the free end of the roller axle to provide an interior area for accommodating appropriate securing means between the core and axle.
  • a removable cap is provided for covering the end recess to keep paint therefrom.
  • FIG. I is a perspective view, partially cut away and in section of a paint roller embodying the core structure of the present invention:
  • FIG. 2 is a vertical section taken generally along the line 2-2 in FIGS. 1 and 3;
  • FIG. 3 is a fragmented vertical section taken generally along the line 33 of FIG. 2;
  • FIG. 4 is aside elevational view of the core structure taken generally in the direction of arrow A (FIG. 2).
  • the core structure of the present invention is particularly adapted for use in a paint roller.
  • a paint roller generally designated 10. having a handle 12 and an axle I4 disposed at generally right angleswith respect to the handle 12.
  • the core structure. generally designated 16. ofthe present invention is rotatably mounted on the axle I4 for axially receiving a cylindrical paint applying sleeve.
  • the sleeve is of substantially conventional form including a paint applying matting 18a backed by a layer 18b and a relatively rigid support backing layer 18c.
  • the core structure of the present invention includes a pair of substantially identical generally parallel longitudinal plates 20 which are spaced from. on opposite sides of and generally parallel to the axis of the axle 14.
  • the plates have longitudinal edge portions 22 engageable with the interior of the paint applying sleeve I8 for rigidly supporting the sleeve generally in the planes of the plates.
  • a longitudinal rib 24 is molded integrally with the plates 20 and are disposed on the outsides thereof generally parallel to the axle 14.
  • the ribs 24 protrude generally radially outwardly from the axle and plates a distance sufficient to provide longitudinal edges 26 providing rigid edge support for the interior of the paint applyling sleeve 18 generally in the plane of the ribs 24. at right angles to the plates 20.
  • the plates 20 and ribs 24 provide longitudinal edge supports for the paint applying sleeve.
  • the plates 20 can flex towardand away from each other generally about the edge junctures 27 with the ribs 24 generally in the directions of arrows X (FIG. 2).
  • the edge portions 22 of the plates and the edge portions 26 of the ribs are slightly curved or chamfered as seen best in FIG. 2.
  • the core structure 16 is journalled on the axle 14 by means of a pair ofinterior webs. generally designated 28. and a pair ofend webs. generally designated 30. all of which are molded integrally with and extending between the plates 20.
  • the webs 30 are provided with full cylindrical journal portions 32 for embracing the axle 14.
  • the webs 28 are provided with offset pairs of semi-cylindrical portions 34a and 34b for disposition about the axle l4. Either one ofthe configurations of webs 28 or 30 provide configurations to permit molding dies to be separated in the direction of arrows B (FIG. 2).
  • a pair of end discs. generally designated 36a and 36b. are molded integrally with and at the ends of the plates 20.
  • the end discs 36a. 3612 have diameters to provide peripheral circular support for the interior of the paint applying sleeve 18, as at 38 in FIG. 3.
  • the end discs facilitate sealing the interior of the core from the seepage thereinto of paint.
  • the end disc 3712 which is disposed at the free end of the axle 14 is recessed. as at 40, to provide an interior area for accommodating appropriate securing means between the core and axle.
  • a removable end cap. generally designated 42, is provided to cover the recess 40 by snapping over a shoulder 44 of the end disc 36!). to prevent the seepage into the recess of paint.
  • the ribs 24 are interrupted and the plates are reduced in size generally in the areas designated by arrows C. This permits limited inward flexing of the plates in the plane of the ribs 24.
  • the plates are reduced in size at areas C. but they remain higher than the interior webs 28.
  • 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.
  • journal means is formed on a plurality of longitudinally spaced webs extending between and molded integrally with said plates.
  • 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.
  • journal means is formed on a plurality of longitudinally spaced webs extending between and molded integrally with said plates.
  • 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 pey 4 ripheral circular support with the interior of said paint applying sleeve generally at theends thereof.
  • 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 cngageable along the edges thereof with the interior of said paint applying sleeve for rigidly supporting the sleeve generally in the planes of said plates.
  • 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.
