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 comprising:
an extension tube having a distal end and a proximal end;
a spray head mounted on the distal end of the extension tube;
an in-line valve mounted on the proximal end of the extension tube; and
a roller handle removably mounted on the extension tube adjacent to the spray head, the roller handle including a handle configured to clamp onto a portion of the extension tube located rearward of the distal end of the extension tube and the spray head, and a support structure extending from the handle beyond the spray head and the distal end of the extension tube to position a paint roller forward of the spray head.

2. The spray roller system of claim 1 , wherein the handle includes a shell having a longitudinal interior channel with a side opening that allows the shell to slide laterally on to and off of the extension tube.

3. The spray roller system of claim 2 , wherein the extension tube has exterior surfaces that mate with interior surfaces of the interior channel of the shell to prevent rotation of the handle when the handle is clamped on the extension tube.

4. The spray roller system of claim 3 , wherein the exterior surfaces of the extension tube include a flat top surface and a flat bottom surface.

5. The spray roller system of claim 2 , wherein the extension tube includes a plurality of exterior circumferential ribs, and wherein the interior channel of the shell has a feature that engages at least some of the exterior circumferential ribs of the extension tube to define a longitudinal location of the handle on the extension tube and to prevent longitudinal movement of the handle on the extension tube.

6. The spray roller system of claim 2 , wherein the handle includes a door that covers the side opening when the door is in a closed position.

7. The spray roller system of claim 6 , wherein the handle includes a latch for maintaining the door in the closed position when the handle is clamped onto the extension tube.

8. The spray roller system of claim 7 , wherein the latch is pivotally connected to the shell and is pivotally connected to the door.

9. The spray roller system of claim 1 , wherein the spray head includes a spray valve, a spray tip, and a spray guard.

10. The spray roller system of claim 9 , wherein the spray valve is connected to the extension tube through a swivel coupling that allows orientation of the spray valve with respect to the paint roller to be adjusted.

11. The spray roller system of claim 9 , wherein the spray valve is configured to automatically prevent dripping when the spray tip is lowered below horizontal.

12. The spray roller system of claim 9 , wherein longitudinal position of the roller handle on the extension tube is adjustable to permit user adjustment of distance between the spray tip and the paint roller.

13. The spray roller system of claim 1 , wherein the roller handle is mountable on the extension tube and removable from the extension tube without use of tools.

14. The spray roller system of claim 1 , wherein the support structure is adjustable to receive and hold roller covers of different widths.

15. The spray roller system of claim 1 , wherein the in-line valve includes 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.

16. The spray roller system of claim 1 , wherein the roller handle, when removed from the extension pole, is configured for use as a hand roller, and the extension pole, in-line valve and spray head are configured for use as a spray extension.

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

18. A spray roller system comprising:
an extension tube having a distal end and a proximal end;
a spray head mounted on the distal end of the extension tube, the spray head including a spray valve, a spray guard, and a spray tip;
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; and
a roller handle removably mounted on the extension tube adjacent the spray head, the roller handle including a handle configured to be clamped onto a portion of the extension tube located rearward of the distal end of the extension tube and the spray head, and a support structure extending from the handle beyond the spray head and the distal end of the extension tube to position a paint roller forward of the spray head.

19. The spray roller system of claim 18 , wherein the handle includes a shell having a longitudinal interior channel with a side opening that allows the shell to slide laterally on to and off of the extension tube.

20. The spray roller system of claim 19 , wherein the extension tube has exterior surfaces that mate with interior surfaces of the interior channel of the shell to prevent rotation of the handle when the handle is clamped on the extension tube, wherein the extension tube includes a plurality of exterior circumferential ribs, and wherein the interior channel of the shell has a feature that engages at least some of the exterior circumferential ribs of the extension tube to define a longitudinal location of the handle on the extension tube and to prevent longitudinal movement of the handle on the extension tube.

21. The spray roller system of claim 19 , wherein the handle includes a door that covers the side opening when the door is in a closed position, and a latch for maintaining the door in the closed position when the handle is clamped onto the extension tube.

22. The spray roller system of claim 21 , wherein the latch is pivotally connected to the shell and is pivotally connected to the door.

23. The spray roller system of claim 18 , wherein the spray valve is connected to the extension tube through a swivel coupling that allows orientation of the spray valve with respect to the paint roller to be adjusted.

24. The spray roller system of claim 18 , wherein longitudinal position of the roller handle on the extension tube is adjustable to permit user adjustment of distance between the spray tip and the paint roller.

25. The spray roller system of claim 18 , wherein the roller handle is mountable on the extension tube and removable from the extension tube without use of tools.

26. The spray roller system of claim 18 , wherein the support structure is adjustable to receive and hold roller covers of different widths.

27. A spray roller system comprising:
an extension tube having a distal end and a proximal end;
a spray head mounted on the distal end of the extension tube;
an in-line valve mounted on the proximal end of the extension tube; and
a roller handle removably mounted on the extension tube adjacent to the spray head, the roller handle including a handle configured to clamp onto the extension tube and a support structure extending from the handle to position a paint roller forward of the spray head;
wherein the handle includes a shell having a longitudinal interior channel with a side opening that allows the shell to slide laterally on to and off of the extension tube; and
wherein the extension tube includes a plurality of exterior circumferen
