Patent ID: 8091171

Claim:
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.
