DETAILED DESCRIPTION
[0020] Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways.

Further, "connected" and "coupled" are not restricted to physical or mechanical connections or couplings, and can include electrical connections or couplings, whether direct or a.ndirect.
Finally, as described in subsequent paragraphs, the specific mechanical configurations illustrated in the drawings are intended to exemplify embodiments of the invention. Accordingly, other alternative mechanical configurations are possible, and fall w3.thin the spirit and scope of the present invention.
machine 10 is shown, comprising a [0021] Referring now to Fig. 1, a floor cleaning device 12 used to couple cleaning implements 14, such as..scrubbing pads and brushes, to the cleaning machine 10. Although one particular embodiment of the invention will be described iin connection with a scrubber, it should be clear that the invention has application to other types of floor maintenance vehicles, such as sweepers and the like.
Accordingly, the present invention should not be limited to a scrubber.
[00221 Referring now to Figs. 2-6, one particular embodiment of the coupling device 12 is shown. As will be described in greater detail below, this illustrated coupling device 12 is adapted to move the cleaning implement 14 in an orbital or reciprocating motion. However, the principles shown herein cari be adapted for rotary motion as well.
[0023] As can be seen in Fig. 2, the cleaning implement 14 and coupling device 12 are generally elongated due to the orbital motion of this cleaning device.
However, in other embodiments, the cleaning implement 14 can have a variety of other configurations, such as square, rectangular, circular, other polygonal shapes, and the like.
[0024] Two particular embodinients of the cleaning -imple.ment -14 are shown in Figs. 7 and S. Fig. 7 illustrates a brush type cleani.ng impleiuen.t 14, while Fig. 8 illustrates a cleaning pad type cleaning implement 14. As shown in these figures, both cleaning implements 14 have substantially similar fixation portions 16 that are used to couple the brush or pad to the coupling device 12. The fixation portion 16 and the cleaning portion 18 of the illustrated embodiments are generally trapezoidal shaped, but other configur.ations are possible. The fixation portions 16 have a main body 20 having a.first longitudinal edge 22 and a second longitudinal edge 24 positioned opposite the first longitudinal edge 22. The first and second longitudinal edges 22, 24 are slightly cantilevered over the cleaning element 18.
[0025] A plurality of locating members 26 a're coupled to the top side of the fixation portion 16. These locating members 26 can be made from a variety of materials and can be configured many different ways. In the illustrated embodiment, the locating members 26 are rubber projections that have a generally convex shape. Specifically, the rubber projections have a dome-like or truncated cone confi.guration. As wi13. be discussed below, this type of shape can help to locate or direct the locating members into receiving recesses 28 on the coupling device 12. The projections 26 of this embodiment are formed of rubber to help dampen noise between the cleaning implement 14 and the coupling device 12:
Other materials, however, can be used for this same purpose.
[0026] Althciugh the illustrated embodiment places the projecting locating members 26 on the fixation portion 16 of the cleaning impleinent 14 and the receiving recesses 28 on the coupling de'vice 12, other embodiments can modify this configuration. For example, in some embodihn.ents,.the projections 26 can be placed on the coupling device 12, while the recesses .28 can be placed on the fixation portion 16 of the cleaning implement 14.
Additionally, some embodiments can: utilize a combination of projections 26 and recesses 28 on both the fixation portion 16 of the cleaning implement and the coupling device 12.
[00271 As shown in Fig. 2 and described in greater detail below, the cleaning implement 14, or more specifically, the ffi.xation portion 16 of the cleaning implement 14 is received within the coupling device 12 to connect the cleaning implement 14 to the floor cleaning machine 10.
[00281 The coupling device 12 includes a main body 30 having a pair of slots or channels 32 for receiving the edges 22, 24 of tJse fixation portion.l6 of the cleaning iimplernent 14.
The channels 32 are dinzensioned ai.id configuxed to receive the edges 22, 24 of the fixation portion 16. More specificatly, as shown in Figs. 4 and 5, the channels 32 are dimensioned to allow the fixation portion 16 to easily slide into the coupling device 12, without significant interference or-engagement between the locating members 26 and the body 30 of the coupling device 12.
[0029] As shown in Figs. 2 and 3, one of the channels 32 has a retainer 34 to selectively prevent the cleaning implement 14 from disengaging the coupling device 12. The retainer 34 includes a projection 36 positioned adjacent one end of the channel 32 and intersecting the path defined by the channel 32. The retainer 34 also includes another projection 38 positioned adjacent the other end of the channel 32 and intersecting the path defined by the channel 32. At least one of the projections 36, 38 is ~ electively moveable to a non-intersecting position to allow the cleaning implement 14 to be removed from the coupling device 12. In the illustrated embodiment, only one projection 38 is selectively moveable. -This projection 38 is provided with a lever 40 to provide leverage for an operator to elastically deform the retainer 34 or otherwise move the projection 38. As further illustrated in Fig. 3, the projection 38 located at this end is angled to allow a cleaning implement 14 to be inserted without manually moving the projection 38 with the lever 40.
Rather, due to the angled configuration of the projection 38, the projection 3$ will natura.ily be forced outward when engaged by the edge 22 of the fixation portion 16 of the cleaning irnplement 14 during insertion. 5 '[0030] In the illustrated enibodi.ment, the retainer 34 is.
formed separa.te from the channel 32 and is attached to the channel 32 in a-secondary operatioxi, such as welding. However; in other embodiments, the retainer 34 can be integrally. formed into the channel 32 or the main body porkion 30_ [003].] As shown in Figs. 2-6, the main body portion 30 of the coupling device 12 is -provided with a plurality of recesses 28. These recesses 28 are dimensioned and configured to selectively house or receive portions of the projections 26 extending from the top of the cleaning implement 14. The recesses 28 have a generally concave configuration to receive the projections 26. The generally concave recesses 28 have a dome-like configuration or some what conical configuration, much like the configuration of the projections 26 on the cleaning im.plement 14. Further, the recesses 28 are generally positioned and spaced apart in substantially the same configurati.on as the projections 26 on the cleaning implement 14.
[0032] In operation, a cleaning implement 14, such as the brush shown in Fig.
Accordingly, the present invention should not be limited to a scrubber.
[00221 Referring now to Figs. 2-6, one particular embodiment of the coupling device 12 is shown. As will be described in greater detail below, this illustrated coupling device 12 is adapted to move the cleaning implement 14 in an orbital or reciprocating motion. However, the principles shown herein cari be adapted for rotary motion as well.
[0023] As can be seen in Fig. 2, the cleaning implement 14 and coupling device 12 are generally elongated due to the orbital motion of this cleaning device.
However, in other embodiments, the cleaning implement 14 can have a variety of other configurations, such as square, rectangular, circular, other polygonal shapes, and the like.
[0024] Two particular embodinients of the cleaning -imple.ment -14 are shown in Figs. 7 and S. Fig. 7 illustrates a brush type cleani.ng impleiuen.t 14, while Fig. 8 illustrates a cleaning pad type cleaning implement 14. As shown in these figures, both cleaning implements 14 have substantially similar fixation portions 16 that are used to couple the brush or pad to the coupling device 12. The fixation portion 16 and the cleaning portion 18 of the illustrated embodiments are generally trapezoidal shaped, but other configur.ations are possible. The fixation portions 16 have a main body 20 having a.first longitudinal edge 22 and a second longitudinal edge 24 positioned opposite the first longitudinal edge 22. The first and second longitudinal edges 22, 24 are slightly cantilevered over the cleaning element 18.
[0025] A plurality of locating members 26 a're coupled to the top side of the fixation portion 16. These locating members 26 can be made from a variety of materials and can be configured many different ways. In the illustrated embodiment, the locating members 26 are rubber projections that have a generally convex shape. Specifically, the rubber projections have a dome-like or truncated cone confi.guration. As wi13. be discussed below, this type of shape can help to locate or direct the locating members into receiving recesses 28 on the coupling device 12. The projections 26 of this embodiment are formed of rubber to help dampen noise between the cleaning implement 14 and the coupling device 12:
Other materials, however, can be used for this same purpose.
[0026] Althciugh the illustrated embodiment places the projecting locating members 26 on the fixation portion 16 of the cleaning impleinent 14 and the receiving recesses 28 on the coupling de'vice 12, other embodiments can modify this configuration. For example, in some embodihn.ents,.the projections 26 can be placed on the coupling device 12, while the recesses .28 can be placed on the fixation portion 16 of the cleaning implement 14.
Additionally, some embodiments can: utilize a combination of projections 26 and recesses 28 on both the fixation portion 16 of the cleaning implement and the coupling device 12.
[00271 As shown in Fig. 2 and described in greater detail below, the cleaning implement 14, or more specifically, the ffi.xation portion 16 of the cleaning implement 14 is received within the coupling device 12 to connect the cleaning implement 14 to the floor cleaning machine 10.
[00281 The coupling device 12 includes a main body 30 having a pair of slots or channels 32 for receiving the edges 22, 24 of tJse fixation portion.l6 of the cleaning iimplernent 14.
The channels 32 are dinzensioned ai.id configuxed to receive the edges 22, 24 of the fixation portion 16. More specificatly, as shown in Figs. 4 and 5, the channels 32 are dimensioned to allow the fixation portion 16 to easily slide into the coupling device 12, without significant interference or-engagement between the locating members 26 and the body 30 of the coupling device 12.
[0029] As shown in Figs. 2 and 3, one of the channels 32 has a retainer 34 to selectively prevent the cleaning implement 14 from disengaging the coupling device 12. The retainer 34 includes a projection 36 positioned adjacent one end of the channel 32 and intersecting the path defined by the channel 32. The retainer 34 also includes another projection 38 positioned adjacent the other end of the channel 32 and intersecting the path defined by the channel 32. At least one of the projections 36, 38 is ~ electively moveable to a non-intersecting position to allow the cleaning implement 14 to be removed from the coupling device 12. In the illustrated embodiment, only one projection 38 is selectively moveable. -This projection 38 is provided with a lever 40 to provide leverage for an operator to elastically deform the retainer 34 or otherwise move the projection 38. As further illustrated in Fig. 3, the projection 38 located at this end is angled to allow a cleaning implement 14 to be inserted without manually moving the projection 38 with the lever 40.
Rather, due to the angled configuration of the projection 38, the projection 3$ will natura.ily be forced outward when engaged by the edge 22 of the fixation portion 16 of the cleaning irnplement 14 during insertion. 5 '[0030] In the illustrated enibodi.ment, the retainer 34 is.
formed separa.te from the channel 32 and is attached to the channel 32 in a-secondary operatioxi, such as welding. However; in other embodiments, the retainer 34 can be integrally. formed into the channel 32 or the main body porkion 30_ [003].] As shown in Figs. 2-6, the main body portion 30 of the coupling device 12 is -provided with a plurality of recesses 28. These recesses 28 are dimensioned and configured to selectively house or receive portions of the projections 26 extending from the top of the cleaning implement 14. The recesses 28 have a generally concave configuration to receive the projections 26. The generally concave recesses 28 have a dome-like configuration or some what conical configuration, much like the configuration of the projections 26 on the cleaning im.plement 14. Further, the recesses 28 are generally positioned and spaced apart in substantially the same configurati.on as the projections 26 on the cleaning implement 14.
[0032] In operation, a cleaning implement 14, such as the brush shown in Fig.
7 can be coupled to the floor cleaning machine 10 via the coupling device 12 shown in Figs. 2-6 as follows. First, the cleaning implement 14 is aIigned with the coupling device 12.
Specifically, the cantilevered edges 22, 24 of the hxatioa portion 16 cfthe cleaning implement 14 are aligned with the channels 32 of the coupling device 12. Once this alignment is substantially complete, the cleaning implement 14 can be inserted, pushed, driven, or otherwise forced into the channels 32 of the coupling device 12.
[0033] As the brush 14 enters the coupling device 12, one of the edges of the brush engages the angled projection 3 S of the retainer 34 and forces the retainer to a position that allows the brush 14 to enter the channel 32. During the insertion process, the bottom surface of the cantilevered edges 22, 24 (i.e., the surface facing the floor during operation) preferably slides along the upward facing surface of #he channel 32. With this type of engagement during the insertion process, the brush 14 should be easily inserted without the projections 26 on the brush interfering or substantially engaging the main body portion 30 of the coupling device 12. Once the brush 14 is inserted fiil.ly into the cha.nne132, the angled projection 38 can elastically return to its original position. In this position, the brush 14 is prevented from disengaging the coupling device 12, and more specifically, the cantilevered edge is prevented from backing out of the channel 32.
[0034] Once the brush 14 is fully inserted in the coupling device 12, it will rest within the coupling device 12 as shown in Figs. 4A, SA, and 6A. Specifically, the lower surface of the aantilevered.edges 22, 24 will rest -on the lower portion -of the channe132.
Further, as shown in these faigures, the projections 26 on top -of the cleaning iinplement 14 vir'tll not be engaged with the recesses 28 of the cflupling device 12. However, the.projections,26 may be substantially aligned with the recesses 28 in this position.
[00351 When an operator chooses to utilize the brushes 14, the brush 14 and coupling device 12 will be lowered into contact with a floor. An. actuator, such as a motor or motor and transmission assembly, can be used to lower the brush 14 and coupling device 12 to the floor. The actuator can be used to force the brush 14 against the floor with a desired pressure or force. This will cause the brush 14 to engage the coupling device 12 as shown in Figs. 4A, 5A, and 6A. Specifically, the projections 26 extending from the top of the brush 14 engage the recesses 28 on the main body portion 30 of the coupling device 12. This engagement prevents the brush 14 from moving relative to the coupling device 12 when the brushes 14 are caused to actuate relative to the floor. Assuming that the projections 26 are not perfectly aligned with the recesses 28 prior to the brush 14 being placed in contact with t[he floor, the shape of the projections 26 and recesses 28 should encourage proper alignment and engagement. Specifically, the generally convex shape of the projections 26 combined with the concave shape of the recesses 28 can fumel or otherwise move the brush into proper alignnlent with the coupling device 12.
10036] Once scrubbing operatxons are complete, the actuator can be actiiated to lift the brush 14 and coupli.ng device 12 off of Ehe floor. Once the brush 14 is lifted off of the floor, the brush vvilI rest within the coupling device 12 as shown in Fig. 4A.
[0037] To remove the brush 14 from the coupling device 12, the following stcps can be used. A force can be applied to the lever 40 adjacent the angled projection 38 to move the projection 38 to a position in which it does not substantially intersect the path defined by the channel 32. Once the projection 38 is moved to a position where it does not hinder the removal the brush 14, the brush 14 can be removed from the coupling device 12 by pulling it in the opposite direction that it was inserted.
