Abstract
A spray roller system for application of architectural paints coating, includes an extension tube, a spray head mounted on a distal end of the extension tube, and the in-line valve with a trigger mounted on a proximal end of the extension tube, and a roller handle removable mounted on the extension tube adjacent the spray head. The spray roller system can spray and back roll a coating on a down stroke and roll on each up stroke. When the roller handle is removed from the extension tube, it can be used to hand roll sensitive wall areas. With the roller handle removed, extension tube, spray head, and in-line valve can be used as a spray extension to apply coatings in hard to reach areas.
Claims19
A spray roller system for spraying paint and rolling paint with a roller cover, the spray roller system comprising:
- an extension tube having a distal end and a proximal end, the extension tube extending along an axis;
- a paint roller having an arm and a frame, the frame configured to support the roller cover by the roller cover mounting around the frame, the paint roller mountable to be supported by the extension tube for spray rolling and dismountable relative to the extension tube for spraying with the extension tube without rolling;
- an in-line valve mounted at the proximal end of the extension tube;
- a distal coupling connected to the distal end of the extension tube;
- a spray head connected to the distal coupling, the spray head including a spray tip configured to spray paint and a spray guard positioned forward of the spray tip, wherein the spray head is configured to receive paint from the distal coupling;
- and
- a swivel coupling positioned between and connecting the distal coupling and the spray head, wherein the swivel coupling supports the spray tip and pivots the spray tip relative to the extension tube, and wherein the swivel coupling is configured to pivot the spray tip to aim the spray tip;
- wherein the paint roller is mountable to be supported by the extension tube such that the arm is vertically offset from the axis and positions the roller cover, when the roller cover is mounted on the frame, forward of the spray head and the spray tip and so that the spray head can spray below the roller cover,
- wherein the in-line valve, the extension tube, the distal coupling, the swivel coupling, and the spray head form a paint fluid path for flowing paint to the spray tip and the paint fluid path is maintained throughout mounting of the paint roller to be supported by the extension tube and dismounting of the paint roller relative to the extension tube.
A method of converting a spray roller between spray rolling and spraying without rolling, the spray roller includes an extension tube, a spray head, and a roller, the extension tube is configured to receive paint at a proximal end and flow paint to a distal end, the spray head is mounted on the distal end of the extension tube and the spray head is configured to receive paint from the extension tube, the spray head includes a spray guard and a spray tip configured to spray paint, the roller includes an arm and a frame, the frame configured to support a roller cover that is mountable around the frame, the method comprising:
- fixing the roller relative to the extension tube to secure the roller to the extension tube for spray rolling such that part of the spray roller is positioned rearward of the spray guard and the spray tip and the arm extends forward beyond the spray guard and the spray tip to position the frame and the roller cover forward of the spray guard and the spray tip of the spray head;
- spray rolling with the roller fixed relative to the extension tube;
- repositioning the roller by unfixing the roller, axially translating the roller from a first position relative to the extension tube to a second position relative to the extension tube, refastening the roller relative to the extension tube at the second position, and then resuming spray rolling;
- detaching the roller from being fixed relative to the extension tube to release the roller from the extension tube for spraying with the extension tube and the spray head without rolling such that the roller is unsupported by the extension tube;
- and
- spraying without the roller fixed relative to the extension tube;
- wherein the extension tube and the spray head form a flow path through which paint flows from the proximal end to the distal end of the extension tube and exits through the spray tip of the spray head;
- and
- wherein the spray head remains attached to the extension tube throughout both of the fixing and the detaching of the roller.
A method of converting a spray roller between spray rolling and spraying without rolling, the spray roller includes an extension tube, a spray head, and a roller, the extension tube is configured to receive paint at a proximal end and flow paint to a distal end, the spray head is mounted on the distal end of the extension tube and the spray head is configured to receive paint from the extension tube, the spray head includes a spray guard and a spray tip configured to spray paint, the roller includes an arm and a frame, the frame configured to support a roller cover that is mountable around the frame, the method comprising:
- fixing the roller relative to the extension tube to secure the roller to the extension tube for spray rolling such that part of the spray roller is positioned rearward of the spray guard and the spray tip and the arm extends forward beyond the spray guard and the spray tip to position the frame and the roller cover forward of the spray guard and the spray tip of the spray head;
- spray rolling with the roller fixed relative to the extension tube;
- detaching the roller from the extension tube to release the roller from the extension tube for spraying with the extension tube and the spray head without rolling such that the roller is unsupported by the extension tube;
- and
- spraying without the roller fixed relative to the extension tube;
- and
- hand rolling with the roller to apply paint without spraying when the roller is not fixed relative to the extension tube;
- wherein the extension tube and the spray head form a flow path through which paint flows from the proximal end to the distal end of the extension tube and exits through the spray tip of the spray head;
- and
- wherein the spray head remains attached to the extension tube throughout both of the fixing and the detaching of the roller relative to the extension tube.
A spray roller system for spraying paint and rolling paint with a roller cover, the spray roller system comprising:
- an extension tube having a distal end and a proximal end;
- a paint roller having a handle, an arm, and a frame, the arm extending between the handle and the frame so that the frame is supported by the handle, the frame configured to support the roller cover by the roller cover mounting around the frame, the paint roller mountable to be supported by the extension tube for spray rolling and dismountable relative to the extension tube for spraying with the extension tube without rolling, the handle elongate and integrated into the paint roller so that the paint roller can be used to hand roll to apply paint without the extension tube after removal of the paint roller from mounting relative to the extension tube;
- an in-line valve mounted at the proximal end of the extension tube;
- a distal coupling connected to the distal end of the extension tube;
- a spray head connected to the distal coupling, the spray head including a spray tip configured to spray paint and a spray guard positioned forward of the spray tip, wherein the spray head is configured to receive paint from the distal coupling;
- and
- a swivel coupling positioned between and connecting the distal coupling and the spray head, wherein the swivel coupling supports the spray tip and pivots the spray tip relative to the extension tube, and wherein the swivel coupling is configured to pivot the spray tip to aim the spray tip;
- wherein the paint roller is dismountable relative to the extension tube without removing the spray head from the extension tube for spraying without rolling,
- wherein the in-line valve, the extension tube, the distal coupling, the swivel coupling, and the spray head form a paint fluid path for flowing paint to the spray tip and the paint fluid path is maintained throughout mounting of the paint roller relative to the extension tube and dismounting of the paint roller relative to the extension tube.
