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.

First claim

The invention claimed is:

1. A spray roller system for spraying and rolling paint with a roller cover, the spray roller system comprising:
a tube extension having a distal end and a proximal end;
a spray head mounted at the distal end of the tube extension, the spray head configured to receive paint from the tube extension, the spray head including a spray tip configured to spray paint and a guard positioned forward of the spray tip;
an in-line valve mounted at the proximal end of the tube extension, the in-line valve comprising an inlet, a handle, an outlet, and a trigger, wherein the trigger is actuatable to release paint from the outlet of the in-line valve into the tube extension; and
a paint roller, the paint roller comprising an arm and a frame rotatably mounted on the arm, the frame configured to support the roller cover, the arm fixed to the tube extension such that the paint roller is supported by the tube extension for spray rolling paint, the arm extending proximal of the spray head and extending distal beyond the spray head to position the frame and the roller cover forward of the spray tip of the spray head;
wherein the in-line valve, the tube extension, and the spray head form a paint fluid path for spraying from the spray tip;
wherein the tube extension and the paint roller are configured such that the paint roller can be detached from the tube extension without removing the spray head from the tube extension for spraying without rolling and again fixed to the tube extension without removing the spray head from the tube extension for resuming spray rolling while the paint fluid path is maintained throughout each of detaching and fixing the paint roller relative to the tube extension.

2. The spray roller system of claim 1 , wherein the tube extension includes couplings.

3. The spray roller system of claim 2 , wherein the tube extension further comprises a first section and a second section joined by one of the couplings.

4. The spray roller system of claim 1 , wherein the arm with the attached paint roller is mountable and removable from the tube extension without the use of tools.

5. The spray roller system of claim 1 , wherein the inlet of the in-line valve is configured to receive paint under pressure.

6. The spray roller system of claim 1 , further comprising a clamp configured to fix the paint roller with respect to the tube extension and release the paint roller with respect to the tube extension.

7. The spray roller system of claim 1 , wherein the tube extension includes a plurality of extension tube sections joined together.

8. A spray roller system for spray rolling paint with a roller cover, the spray roller system comprising:
an extension tube having a distal end and a proximal end, the distal end including a distal coupling that defines a distal terminus of the extension tube, the extension tube configured to receive paint at the proximal end and permit flow of paint through the extension tube and out the distal end;
a spray head mounted on the extension tube, the spray head configured to receive paint from the distal end of the extension tube, the spray head including a spray guard, a spray tip configured to spray paint, and a swivel coupling connected to the distal coupling and supporting the spray tip, the swivel coupling located between the distal coupling and the spray tip, the swivel coupling is configured to pivot the spray tip relative to the extension tube;
a clamp; and
a roller comprising an arm and a frame rotatably mounted on the arm, the frame configured to hold the roller cover, the arm configured to be fixed to the extension tube by the clamp such that the arm extends rearward of the spray guard and the spray tip and 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,
wherein the extension tube and the spray head form a flow path through which paint flows from the proximal end to the distal coupling of the extension tube and exits through the spray tip of the spray head;
wherein the clamp is configured such that the roller can be unclamped relative to the tube extension for spraying without rolling and reclamped to fix the roller with respect to the tube extension for resuming spray rolling, and the extension tube and the spray head are configured such that, throughout each of unclamping and reclamping the paint roller relative to the tube extension, the spray head remains attached to the extension tube and the flow path is maintained.

9. The spray roller system of claim 8 , and further comprising:
an in-line valve mounted on the proximal end of the extension tube, the in-line valve including an inlet for receiving paint under pressure, an outlet connected to the proximal end of the extension tube, a grip, and a trigger for opening and closing the in-line valve.

10. The spray roller system of claim 8 , wherein the clamp is configured to unclamp and reclamp the roller relative to the extension tube without tools.

11. The spray roller system of claim 8 , wherein the clamp is configured to mount the arm to the extension tube.

12. The spray roller system of claim 11 , wherein the clamp is configured to attach the arm with the attached roller directly to the extension tube.

13. The spray roller system of claim 8 , wherein the swivel coupling is configured to adjustably pivot the spray tip so that a spray fan produced by the spray tip hits below the roller cover as the roller cover is rolled down.

14. The spray roller system of claim 8 , wherein the extension tube includes tube sections.

15. The spray roller system of claim 8 , wherein the distal end of the extension tube includes a coupling.

16. The spray roller system of claim 8 , wherein the clamp is configured to be released to allow repositioning of the spray tip relative to the roller cover by allowing axial movement of the arm relative to the extension tube and then reclamped to fix the position of the arm relative to the extension tube.

17. A method of converting between spray rolling with a roller cover and spraying without the roller cover with a tube extension, a spray head, and a roller, the tube extension configured to receive paint and having a proximal end and a distal end through which paint can flow, the spray head mounted on the distal end of the tube extension and configured to receive paint from the tube extension, the spray head including a spray guard, a spray tip configured to spray paint, the roller comprising an arm and a frame rotatably mounted on the arm, the frame configured to hold the roller cover, the method comprising:
fixing the roller to the tube extension for spray rolling such that the arm extends rearward of the spray guard and the spray tip and forward beyond the spray guard and the spray tip to position the roller cover forward of the spray guard and the spray tip of the spray head, the fixing of the roller to the tube extension is performed without use of any tool; and
detaching the roller from the tube extension for spraying with the tube extension and the spray head without rolling such that the roller is unsupported by the tube extension the detaching of the roller from the tube extension is performed without use of any tool;
wherein the tube extension 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 and the flow path is maintained throughout both of the
