Abstract

A device and method for coupling a cleaning implement to a floor cleaning machine. The device includes a plate that has a first edge, a second edge, and a main body portion extending between the first edge and the second edge. The device also includes projections and recesses positioned to releasably engage with each other to releasably couple the plate with the cleaning implement, and a channel that is coupled to one of the first edge and the second edge of the plate to receive an edge of the cleaning implement. The channel has a first end for initially receiving the edge of the cleaning implement during insertion, and a second end positioned opposite the first end. A retainer is in communication with the channel to selectively prevent the cleaning implement from disengaging relative to the coupling device.

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;

projections and recesses positioned to releasably engage with each other to releasably couple the plate with the cleaning implement;

a channel coupled to one of the first edge and the second edge of the plate to receive an edge of the cleaning implement, the channel having a first end for initially receiving the edge of the cleaning implement during insertion and a second end positioned opposite the first end; and

a retainer in communication with the channel to selectively prevent the cleaning implement from disengaging relative to the coupling device.

2. The coupling device of claim 1, wherein the retainer has a projection positioned adjacent at least one of the first end and the second end to retain the cleaning implement in engagement with the coupling device.

3. The coupling device of claim 2, wherein the projection is a first projection positioned adjacent the first end and a second projection is positioned adjacent the second end, and wherein at least one of the first projection and the second projection intersects the channel.

4. The coupling device of claim 3, wherein each of the first projection and the second projection intersects the channel, and wherein one of the first projection and the second projection is movable to a non-intersecting position to permit removal of the cleaning implement from the coupling device.

5. The coupling device of claim 2, wherein the projection is selectively movable between a first position in which the projection intersects the channel, and a second position in which the projection is in a non-intersecting position relative to the channel.

6. The coupling device of claim 5, wherein the projection includes a lever operable to move the projection from the first position to the second position.

7. The coupling device of claim 6, wherein the lever is elastically deformable.

8. The coupling device of claim 6, wherein the projection is varied from the first position to the second position in response to insertion of the cleaning implement into the channel.

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 opposite the first edge, and a main body portion extending between the first edge and the second edge;

a first channel at the first edge of the plate to receive a first edge of the cleaning implement; and

a second channel at the second edge of the plate to receive a second edge of the cleaning implement,

wherein the first edge of the cleaning implement is slidably received into an end of the first channel of the plate and the second edge of the cleaning implement is slidably received into an end of the second channel of the plate to install the cleaning implement, and

wherein a projection is movable between a first position in which the projection prevents removal of the cleaning implement from the plate, and a second position in which the cleaning implement is slidably removable from the plate.

10. The coupling device of claim 9, wherein the projection is located on one of the plate and the cleaning implement and is releasably engageable with the other of the plate and the cleaning implement.

11. The coupling device of claim 9, wherein the projection is positioned adjacent at least one of a first end and a second end of the second channel.

12. The coupling device of claim 11, wherein the projection is a first projection positioned adjacent the first end of the second channel, the coupling device further comprising a second projection positioned adjacent the second end of the second channel.

13. The coupling device of claim 12, wherein each of the first projection and the second projection intersects the second channel in the first position.

14. The coupling device of claim 9, wherein the projection is movable to the second position via an elastically deformable lever.

15. The coupling device of claim 9, wherein the projection is moved from the first position to the second position in response to insertion of the 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 including a plate having a main body portion defining an edge;

a channel coupled to the edge of the plate;

a cleaning implement coupled to the coupling device, the cleaning implement including a first surface adapted to contact and clean a floor surface and a second surface positioned substantially opposite the first surface and contacting the plate, the cleaning implement further including a fixation portion engageable with the coupling device within the channel to hold the cleaning implement on the coupling device; and

a retainer in communication with the channel to selectively prevent the cleaning implement from disengaging relative to the coupling device.

17. The floor cleaning machine of claim 16, wherein the cleaning implement includes a cleaning element extending from the first surface, and wherein the fixation portion includes an edge cantilevered over the cleaning element.

18. The floor cleaning machine of claim 16, wherein the edge is disposed in the channel when the cleaning implement is installed on the coupling device.

19. The floor cleaning machine of claim 18, wherein the retainer includes a projection intersecting the channel to hold the cleaning implement on the coupling device.

20. The floor cleaning machine of claim 19, wherein the projection is selectively movable to a non-intersecting position to permit removal of the cleaning implement from the device.
