Abstract

An abrasive scrubbing pad device combined with a wringer mop in which the scrubbing pad when not in use is automatically placed in a physical position which does not interfere with the normal mop function of the mop by an automatic pivoting action brought into operation by actuation of the crank handle of the wringer mop. When the crank handle of the wringer mop is moved to the position where the mop head is functional for mopping purposes, the scrubber pad is pivoted out of the way, and when the actuating handle is operated to retract the mop head between the wringer rollers during a squeeze-out operation, the scrubber pad is pivoted into its operating position. The scrubber pad may be incorporated into the mop when originally asssembled or may be added to the mop at a later time. The scrubber pad structure is formed so that the scrubber pad itself may be replaced in the support structure when the pad has been rendered no longer useful by virtue of wear.

Claims

1. A scrubber head for use in combination with a wringer mop of the type having at least one rotatable wringer roller extending substantially orthogonally and in spatially fixed position to a mop handle, a mop head having a surface engagingly underlying the wringer roller and adapted to having its wringer engaging surface translated with respect to the roller to rotate the latter and wring out the mop head, and an actuating member effective to translate the wringer engaging surface of the mop head in opposite directions to effect opposite rotations of the roller and to alternately wring out the mop head and restore it to use position, said scrubber head comprising in combination,

(a) a scrubber pad,

(b) scrubber pad support means which mechanically support said scrubber pad, and

(c) pivot means connected to said scrubber pad support means and being also couplable to the wringer roller of the wringer mop for rotation therewith when the wringer roller is rotated by the engaging surface of the mop head, said scrubber pad support means being pivoted up out of the way when the mop head actuating member moves the mop head into use position and being pivoted down into working scrubbing position when the mop head actuating member moves the mop head to wring it out.

2. The combination as set forth in claim 1 wherein said pivot means is couplable to the roller by capture means and is frictionally engaged with the roller so as to rotate with it.

3. The combination as set forth in claim 2 wherein said scrubber pad is adhesively secured to said scrubber pad support means.

4. The combination as set forth in claim 2 wherein said scrubber pad is secured on a mount which captively interfits with said scrubber pad support means, and further including locking means carried by one of said scrubber pad support means and scrubber pad mount for releasably locking said scrubber pad mount to said scrubber pad support means.

5. The combination as set forth in claim 1 wherein said pivot means is couplable to the roller by capture means and is key engaged with the roller so as to rotate with it.

6. The combination as set forth in claim 5 wherein said scrubber pad is adhesively secured to said scrubber pad support means.

7. The combination as set forth in claim 5 wherein said scrubber pad is secured on a mount which captively interfits with said scrubber pad support means, and further including locking means carried by one of said scrubber pad support means and scrubber pad mount for releasably locking said scrubber pad mount to said scrubber pad support means.

8. The combination as set forth in claim 1 wherein the wringer roller consists of an axle with hollow cylindrical roller segments of larger diameter mounted thereon and wherein said pivot means further includes capture means for holding itself captive to the roller axle and is frictionally engaged with the end face of an adjacent one of said cylindrical roller segments of larger diameter.

9. The combination as set forth in claim 8 wherein said scrubber pad is adhesively secured to said scrubber pad support means.

10. The combination as set forth in claim 8 wherein said scrubber pad is secured on a mount which captively interfits with said scrubber pad support means, and further including locking means carried by one of said scrubber pad support means and scrubber pad mount for releasably locking said scrubber pad mount to said scrubber pad support means.

11. The combination as set forth in claim 1 wherein the wringer roller consists of an axle with hollow cylindrical roller segments of larger diameter mounted thereon, and wherein said pivot means further includes capture means for holding itself captive to the roller axle, and is key engaged with the end face of an adjacent one of said cylindrical roller segments of larger diameter.

12. The combination as set forth in claim 11 wherein said scrubber pad is adhesively secured to said scrubber pad support means.

13. The combination as set forth in claim 11 wherein said scrubber pad is secured on a mount which captively interfits with said scrubber pad support means, and further including locking means carried by one of said scrubber pad support means and scrubber pad mount for releasably locking said scrubber pad mount to said scrubber pad support means.

14. The combination as set forth in claim 1 wherein said pivot means comprises a pair of spaced apart pivot arms each fixedly connected at one of their ends to a different place along said scrubber pad support means, and each having its other end couplable to the wringer roller at different places therealong.

15. The combination as set forth in claim 14 wherein said scrubber pad is adhesively secured to said scrubber pad support means.

16. The combination as set forth in claim 14 wherein said scrubber pad is secured on a mount which captively interfits with said scrubber pad support means, and further including locking means carried by one of said scrubber pad support means and scrubber pad mount for releasably locking said scrubber pad mount to said scrubber pad support means.

17. The combination as set forth in claim 14 wherein said pivot means pivot arms are couplable to the roller by capture means and are frictionally engaged with the roller so as to rotate with it.

18. The combination as set forth in claim 17 wherein said scrubber pad is adhesively secured to said scrubber pad support means.

19. The combination as set forth in claim 17 wherein said scrubber pad is secured on a mount which captively interfits with said scrubber pad support means, and further including locking means carried by one of said scrubber pad support means and scrubber pad mount for releasably locking said scrubber pad mount to said scrubber pad support means.

20. The combination as set forth in claim 14 wherein said pivot means pivot arms are couplable to the roller by capture means and are key engaged with the roller so as to rotate with it.

21. The combination as set forth in claim 20 wherein said scrubber pad is adhesively secured to said scrubber pad support means.

22. The combination as set forth in claim 20 wherein said scrubber pad is secured on a mount which captively interfits with said scrubber pad support means, and further including locking means carried by one of said scrubber pad support means and scrubber pad mount for releasably locking said scrubber pad mount to said scrubber pad support means.

23. The combination as set forth in claim 14 wherein the wringer roller consists of an axle with hollow cylindrical roller segments of larger diameter mounted thereon, and wherein said pivot means pivot arms each further includes capture means for holding itself captive to the roller axle and is frictionally engaged with the end face of an adjacent one of said cylindrical roller segments of larger diameter.

24. The combination as set forth in claim 23 wherein said scrubber pad is adhesively secured to said scrubber pad support means.

25.
