Abstract

A device and method for coupling a floor cleaning implement to a floor cleaning machine. The device and method selectively couple a floor cleaning implement, such as a pad or brush, in manner that can be easily released and connected. In one embodiment the coupling device comprises a plate having a first and second channel coupled to opposite edges of the plate. The channels are dimensioned and configured to receive edges of the cleaning implement. At least one channel has projecting members that selectively prevent the cleaning implement from leaving the channel. In some embodiments, the plate has a plurality of recesses dimensioned and configured to selectively receive projections extending from the cleaning implement. The projections of the cleaning implement only fully engage the recesses of the coupling device when an actuator presses the cleaning implement against a floor.

Claims

1. A device for coupling a cleaning implement to a floor cleaning machine, the coupling device comprising:

a plate having a first edge, a second edge, and a main body portion extending between the first edge and the second edge, the main body portion having a plurality of concave recesses dimensioned and configured to selectively receive convex projections extending from the cleaning implement;

a first channel is coupled to the first edge of the plate, the first channel is dimensioned and configured to receive a first edge of the cleaning implement; and

a second channel is coupled to the second edge of the plate, the second channel is dimensioned and configured to receive a second edge of the cleaning implement, the second channel has a first end for initially receiving the edge of the cleaning implement during insertion and a second end positioned adjacent a projecting member that prevents the cleaning implement from leaving the second channel via the second end, the first end of the second channel has a selectively moveable projecting member that selectively prevents the cleaning implement from leaving the second channel via the first end.

2. The device of claim 1, further comprising at least one convex projection positioned on the main body portion, the at least one convex projection dimensioned and configured to selectively extend into at least one concave recess on the cleaning implement.

3. The device of claim 1, wherein the first and second channels are dimensioned to permit substantially vertical movement of the cleaning implement within the channels.

4. The device of claim 3, wherein the concave recesses are positioned to receive the convex projections upon the substantially vertical movement of the cleaning implement.

5. The device of claim 1, wherein the first and second channels extend in a substantially horizontal direction in use of the device.

6. The device of claim 1, wherein the selectively moveable projecting member permits insertion of cleaning implement into the second channel.

7. The device of claim 1, wherein at least one of the convex projections comprises a vibration-dampening material.

8. The device of claim 1, wherein the concave recesses each have a substantially truncated cone shape.

9. A device for coupling a cleaning implement to a floor cleaning machine, the coupling device comprising:

a plate having a first edge, a second edge, and a main body portion extending between the first edge and the second edge, the main body portion having a plurality of substantially convex projections extending toward the cleaning implement and dimensioned and configured to be selectively received within substantially concave recesses on the cleaning implement;

a first channel is coupled to the first edge of the plate, the first channel is dimensioned and configured to receive a first edge of the cleaning implement; and

a second channel is coupled to the second edge of the plate, the second channel is dimensioned and configured to receive a second edge of the cleaning implement, the second channel has a first end for initially receiving the edge of the cleaning implement during insertion and a second end positioned adjacent a projecting member that prevents the cleaning implement from leaving the second channel via the second end, the first end of the second channel has a selectively moveable projecting member that selectively prevents the cleaning implement from leaving the second channel via the first end.

10. The device of claim 9, wherein at least one of the convex projections comprises a vibration-dampening material.

11. The device of claim 9, wherein the convex projections each have a substantially truncated cone shape.

12. The device of claim 9, wherein the first and second channels are dimensioned to permit substantially vertical movement of the cleaning implement within the channels.

13. The device of claim 12, wherein the concave recesses are positioned to receive the convex projections upon the substantially vertical movement of the cleaning implement.

14. The device of claim 9, wherein the first and second channels extend in a substantially horizontal direction in use of the device.

15. The device of claim 9, wherein the selectively moveable projecting member permits insertion of cleaning implement into the second channel.

16. A floor cleaning machine comprising:

a frame;

an actuator coupled to the frame;

a coupling device coupled to the actuator; and

a cleaning implement coupled to the coupling device, the cleaning implement comprises a first surface adapted to contact and clean a floor surface and a second surface positioned substantially opposite the first surface and adapted to contact the coupling device, the second surface having a plurality of projecting members that extend from the second surface, the cleaning implement also has substantially opposite first and second edges extending from the second surface toward the first surface;

wherein the coupling device includes;

a plate having a first edge, a second edge, and a main body portion extending between the first edge and the second edge, the main body portion having a plurality of concave recesses dimensioned and configured to selectively receive the projections extending from the cleaning implement;

a first channel is coupled to the first edge of the plate, the first channel is dimensioned and configured to receive the first edge of the cleaning implement; and

a second channel is coupled to the second edge of the plate, the second channel is dimensioned and configured to receive the second edge of the cleaning implement, the second channel has a first end for initially receiving the second edge of the cleaning implement during insertion and a second end positioned adjacent one of the projecting members that prevents the cleaning implement from leaving the second channel via the second end, the first end of the second channel has a selectively moveable projecting member that selectively prevents the cleaning implement from leaving the second channel via the first end;

wherein the projections of the cleaning implement only engage the recesses of the coupling device when the actuator presses the cleaning implement against a floor.

17. The device of claim 16, wherein at least one of the projecting members comprises a vibration-dampening material.

18. The device of claim 16, wherein the projecting members each have a substantially truncated cone shape.

19. The device of claim 16, wherein the first and second channels are dimensioned to permit substantially vertical movement of the cleaning implement within the channels.

20. The device of claim 16, wherein the selectively moveable projecting member permits insertion of cleaning implement into the second channel.
