The object of the invention is to provide a cleaning machine of the type mentioned in the introduction, in which the cleaning roller on the roller housing can be exchanged in a simple manner.

In the case of the cleaning machine mentioned at the outset, this object is achieved according to the invention in that at least one convex holding body is arranged on the roller housing, a pivotable bracket is arranged on the cover, at least one receptacle for the at least one holding body is arranged on the pivotable bracket, and that in a release position of the pivotable bracket, the at least one holding body can be immersed in the associated receptacle and/or can be exchanged from the associated receptacle and in a locking position of the pivotable bracket, emergence of the holding body from the associated receptacle is blocked.

In the solution according to the invention, the cover can be fixed to and detached from the roller housing in a simple manner and in particular without the use of tools. The number of components required is minimized.

It is easy to use for the user; by pivoting the pivotable bracket with the at least one receptacle, it can bring the cover from the locked position into a release position or, conversely, from the release position into a locked position.

The measures on the roller housing for fixing the cover can be carried out in a structurally simple manner. The locking can be achieved solely with the at least one convex holding body.

It is favorable if the at least one convex holding body is designed as a holding ball. Locking can thus be achieved in a simple manner. Furthermore, a transition between a release position and a locking position and between a locking position and a release position can be achieved in a simple manner. A pivot bearing can be provided via a retaining ball arranged on a receptacle.

It is favorable if the at least one receptacle has a receptacle space for the associated holding body. The corresponding convex holding body can be positioned in the receiving space, in particular in the form of a sphere. Depending on the position of the recording, an emergence or immersion can be achieved or such an emergence can be blocked.

Conveniently, the receiving space has a spherical boundary. This provides a type of ball bearing for the holding body in the receptacle; the release position can be easily reached from the locked position.

It is particularly advantageous if the receiving space has a first opening and a second opening, the holding body being able to be inserted through the first opening and the holding body not being able to be inserted through the second opening. The position of the first opening and the second opening relative to the roller housing is determined by a pivoting position of the pivotable bracket. The holding body can then be brought into the associated receiving space through the first opening in a simple manner. By pivoting the bracket, the receiving space with the second opening can be positioned in such a way that the holding body is prevented from emerging.

In particular, the holding body is seated on a neck, with the neck being positioned in the second opening in the locking position. The holding body has larger width dimensions than the neck. The neck is a type of ball neck. By positioning in the second opening block an emergence of the holding body from the corresponding receiving space in a simple manner. This blocking can be canceled in a simple manner by pivoting the corresponding receptacle.

In particular, it is provided that the neck is positioned in the second opening by pivoting the pivotable bracket from the release position into the locking position with the holding body positioned in the receiving space. In this way, it is possible in a simple manner to block the corresponding holding body from emerging from the associated receiving space.

It is favorable if the first opening and the second opening are connected to one another. As a result, a transition between the release position and the locking position and vice versa can be achieved in a simple manner by a pivoting movement of the pivotable bracket.

In one embodiment, at least one first convex holding body is arranged on the roller housing and a second convex holding body is arranged at a distance from the first holding body, and a first receptacle for the first holding body and a second receptacle for the second holding body are arranged on the pivotable bracket. This allows the cover to be locked to the roller housing at at least two points. A good closure of the roller receptacle on the roller housing can thus be achieved.

In particular, a pivot bearing for pivoting the pivotable bracket is arranged between the first receptacle and the second receptacle. This results in a compact structure for the roller housing and the cover. The number of required components can be kept low.

In one embodiment, the pivotable bracket is oriented transversely and in particular perpendicularly to the cover in the release position. This can open a release position can be easily achieved by pivoting into this transverse position.

It is favorable if, in the locked position, the pivotable bracket is oriented at least approximately parallel to the cover. As a result, it protrudes only minimally or not at all over the lid. In the locked position, a working position for the cleaning machine is reached.

In one embodiment, a recess for receiving the pivotable bracket in the locking position is arranged on the cover, and in particular when the pivotable bracket is arranged in the recess, it does not protrude beyond a surface of the cover. As a result, the bracket can be arranged in a recessed manner on the cover in the locked position.

It is favorable if an immersion direction and/or an emergence direction of the at least one holding body for the associated receptacle is oriented transversely and in particular perpendicularly to a pivot axis of the pivotable bracket. This results in a simple structural design. Furthermore, it is easy to use.

In one embodiment, a pivoting angle of the pivotable bracket between the release position and the locking position is in the range between 70° and 110° and in particular at least approximately 90°. A transition between the release position and the locking position and vice versa can thus be achieved in a simple manner by pivoting the pivot bracket.

In one embodiment, the pivotable bracket has a first portion on which a first receptacle is located and a second portion on which a second receptacle is located and a third portion intermediate the first portion and the second area lies. For example, the third area can be used Form a grip area for grasping the bracket for a pivoting movement. This results in a compact structure with optimized use of space.

In particular, the third area is designed as an arch. As a result, it can be grasped in a simple manner. The result is an optimized use of space on the cover.

It is also favorable if a pivot bearing is arranged or formed on the first area and/or the second area. As a result, the corresponding locking device can be designed in a structurally simple manner and in a space-optimized manner.

In one embodiment, a drive motor is provided for driving the at least one cleaning roller in rotation, with the drive motor in particular being arranged on the roller housing. In principle, it is also possible for the operator to move the roller housing over a surface to be cleaned to drive a rotational movement of the at least one cleaning roller.

It is favorable if a bearing for the at least one cleaning roller is arranged on the cover for the rotatable mounting of the at least one cleaning roller. As a result, the at least one cleaning roller in the roller housing can also be supported on the cover. In particular, a two-point mounting for the at least one cleaning roller in the roller housing can be achieved in this way.

It is provided that when the cover is fixed in the roller housing, the cover covers the at least one holding body on the outside. This results in optimized coverage.

It is favorable if the cover can be completely removed from the roller housing and, in particular, the at least one cleaning roller can be removed from the cover is solvable. In this way, a cleaning roller can be exchanged in a simple manner.

In one embodiment, the roller housing has an end wall assigned to the roller receptacle, the opening being formed on the end wall, and the at least one convex holding body being arranged on the end wall. This results in a structurally simple and compact construction of the roller housing. The cover can be easily locked to the roller housing.

• eine Schwenkachse des schwenkbaren Bügels ist in einem spitzen Winkels zu einer (unteren) Einhüllendenebene des Walzengehäuses angeordnet.

In particular, at least one of the following is provided:

• a pivot axis of the pivotable bracket is arranged transversely and in particular perpendicularly to an axis of rotation of the at least one cleaning roller;
• a pivot axis of the pivotable bracket is arranged at an acute angle to a (lower) envelope plane of the roller housing.

This results in a compact structure. The cover can be easily locked to and removed from the roller housing.

It is favorable if the roller receptacle has an opening towards an envelope plane (towards a lower envelope plane) of the roller housing. This opening is in particular a suction opening or suction port on the roller housing.

In one embodiment, a locking device is provided for releasably locking the at least one cleaning roller to the cover. It is thus possible, when the cover is locked to the at least one cleaning roller, to remove the corresponding cleaning roller with the cover and also by means of the cover from the roller receptacle. Further the cleaning roller can be inserted over the lid. This results in easy removal and automatic alignment can be implemented. This makes it easier to remove or insert the cleaning roller.

It is favorable if the locking device is designed for an axial locking between the cover and the at least one cleaning roller and in particular allows a rotation between the at least one cleaning roller and the cover. This results in easy operability.

In one embodiment, the locking device comprises a pin, which is arranged on the at least one cleaning roller, and comprises a movable slide, which is arranged on the cover, with locking engagement of the slide on the pin, an axial lock between the cover and the at least one cleaning roller present. The axial locking allows in particular a rotation of the at least one cleaning roller relative to the cover. In this way, an axial locking can be achieved in a simple manner, which can be released in a simple manner.

The at least one cleaning roller is a brush roller and/or textile roller, for example. It is possible for a textile trimming and a brush trimming to be combined on a cleaning roller. In one embodiment, the cleaning roller is designed as a carpet brush.

In one embodiment, the cleaning machine is designed as a floor cleaning machine and in particular as a suction machine and in particular as a carpet brush vacuum cleaner.

It is then favorable if at least one suction opening is formed on the roller mount. Dirt can be sucked in through these. The roller receptacle is then also in fluid communication with a suction fan device.

An exemplary embodiment of a cleaning machine 10 according to the invention is a brush suction machine (carpet brush suction device), which in figure 1 shown in perspective.

The cleaning machine 10 comprises a floor head 12 with a roller housing 14.

The floor head 12 is attached to a surface 16 to be cleaned (cf figure 2 ) via a wheel device 18 can be supported.

In one embodiment, the wheel assembly 18 includes wheels 20, specifically having a left rear wheel and a right rear wheel. The wheels 20 are arranged in the area of a rear end of the floor head 12 .

Furthermore, one or more rollers 22 are arranged at a distance from the wheels 20 on the floor head.

The cleaning machine 10 comprises a holding rod device 24 on which a handle 26 is arranged at a proximal end. Using the handle 26, an operator can guide the cleaning machine 10 standing over the surface 16 to be cleaned.

In one embodiment, the support rod assembly 24 includes a single support rod 28. A housing 30 is disposed on the support rod 28. As shown in FIG. An aspirator assembly 32 is positioned within the housing 30 . The suction fan device 32 comprises a fan motor, which is in particular an electric motor, and a corresponding fan device with one or more impellers.

The housing 30 or the support rod device 24 is connected to the floor head 12 and in particular is pivotably connected in such a way that the support rod device 24 can be pivoted about a pivot axis to the floor head 12 when the floor head 12 is supported on the surface 16 to be cleaned. This pivot axis is then at least approximately parallel to the surface 16 to be cleaned.

(At least) one suction port 34 is formed on the roller housing 14 . This has a fluid effect with the suction fan device 32.

In one exemplary embodiment, the cleaning machine 10 also has a suction pipe 36 on which, in particular, a suction nozzle is seated or can be positioned. The suction pipe 36 is fluidly connected to the suction fan device 32 by a particularly flexible suction hose 38.

A holder 40 for the intake manifold 36 is arranged on the housing 30 .

A user can perform suction separately from the suction mouth 34 via the suction tube 36 when it is removed from the holder 40 .

The roller housing 14 has a roller mount 42 . This roller seat 42 is arranged in the region of a front end 44 of the soil head 12 (the roller housing 14) which is remote from the end at which the wheels 20 are arranged.

The roller mount 42 is open at the suction port 34 . Otherwise it is closed.

The roller mount 42 (compare, for example, also figure 12 ) is used to hold a cleaning roller 46.

In an exemplary embodiment of a brush suction machine, the cleaning roller 46 is a brush roller with a bristle stock 48. The bristle stock 48 is arranged in particular in such a way that the cleaning roller 46 acts as a carpet brush.

In principle, it is also possible for the cleaning roller 46 to be a textile roller or for the cleaning roller 46 to be a combination of a textile roller and a brush roller.

The cleaning roller, when it is positioned and fixed in the roller housing 14 and thereby in the roller receptacle 42, can be rotated about an axis of rotation 50 (compare, for example, Figures 3 and 12 ).

The axis of rotation 50 is at least approximately parallel to the surface 16 to be cleaned when the floor head 12 is properly positioned on it and supported by the wheel assembly.

The roller mount 42 is associated with an end wall 52 on the roller housing 14 (cf Figures 3 , 8th , 12 ).

In this end wall 52 an opening 54 is formed. The opening 54 is an opening of the roller mount 52.

The cleaning roller 46 can be brought into the roller receptacle 42 through this opening 54 or the cleaning roller 46 can be removed from the roller receptacle 42 and thus from the floor head 12 through the opening 54 .

A wall 56 , which is closed, is also associated with the roller receptacle 42 opposite the opening 54 . The wall 56 is a side wall of the roller housing 14. A pivot bearing 58 for the cleaning roller 46 is arranged on this wall 56. FIG. The cleaning roller 46 has a counter element 60 for this pivot bearing 58 . In particular, the cleaning roller 46 can be pushed onto the rotary bearing 58 with the counter-element 60 .

In one embodiment it is provided that a drive motor 62 (cf figure 2 ) for the rotary movement of the cleaning roller 46 is arranged. The drive motor 62 acts, for example, via a belt drive on the cleaning roller 46 and drives it to rotate. For example, the drive motor 62 acts on the pivot bearing 58 in order to bring about a corresponding rotation, and the cleaning roller 46 can be connected to the pivot bearing 58 in a rotationally fixed manner via the counter-element 60 .

A cover 64 is provided to close the opening 54 .

A pivot bearing 66 is arranged on the cover 64 . If the opening 54 is closed with the cover 64 , then the rotary bearing 66 supports the cleaning roller 46 on the cover 64 so that it can rotate about the axis of rotation 50 .

The cover 64 can be removed from the roller housing 14 as a whole and is a part that is separate from the roller housing 14 and can be fixed to the roller housing 14 .

The shape of the cover 64 is adapted to the opening 54 .

A bracket 69 is seated on the cover 64 so that it can be pivoted about a pivot axis 68.

The pivot axis 68 is oriented transversely and in particular vertically in relation to the axis of rotation 50 . In relation to a lower envelope plane 70 of the roller housing 14 (cf figure 2 ), wherein in particular the lower envelope plane 70 is related to the roller housing 14 without wheel device 18, and which is aligned at least approximately parallel to the surface to be cleaned 16 when the floor head 12 is properly positioned with respect to it, the pivot axis 68 is at an acute angle 72 (compare figure 2 ). This acute angle is, for example, of the order of about 30° and in particular in the range between 20° and 40°.

The bracket 69 is arranged on an outer side 74 of the cover 64 .

The pivot bearing 66 is arranged on an inner side 76 of the cover 64 opposite the outer side 74 .

The bracket 69 has (compare for example figure 4 ) a first region 78 and a second region 80 spaced apart from the first region 78. The first region 78 and the second region 80 are at least approximately straight.

Between the first area 78 and the second area 80 a third area 82 is formed, which is arcuate.

A first receptacle 84 for a first convex holding body 86 of the roller housing 14 is seated in the first region 78.

A second receptacle 88 for a second convex holding body 90 of the roller housing 14 is located on the second region 80 at a distance from the first receptacle 84.

The first receptacle 84 and the second receptacle 88 are arranged on the bracket 69 in a rotationally fixed manner. When the bracket 69 is pivoted, the first receptacle 84 and the second receptacle 88 are pivoted with it.

The bracket 69 is held pivotably on the cover 64 via a pivot bearing 92 . The pivot bearing 92 includes a first bearing portion 94 seated on the first portion 78 and a second bearing portion 96 seated on the second portion 80 of the bracket 69 . The first bearing area 94 and the second bearing area 96 are spaced apart from one another. The third area 82 of the bracket 69 is arranged between them.

The first receptacle 84 and the second receptacle 88 lie on a line which is defined by the pivot axis 68 .

The first holding body 86 (compare the figures 6 , 11 , 14 ) is convex and formed in particular as a sphere. It sits on the end wall 52 via a first neck 98. The second holding body 90 is also convex in design and is in particular designed as a holding ball. It sits on the end wall 52 at a distance from the first holding body 86 via a second neck 100. The opening 54 is located between the first holding body 86 and the second holding body 90.

The first receptacle 84 and the second receptacle 88 each include a receiving space 102 for the associated holding body 86 or 90 (cf figure 5 , 6 , 8th , 10 , 11 ).

The receiving space 102 has a first opening 104 ( figures 10 , 11 ), through which the associated first holding body 86 or second holding body 90 can be immersed. The corresponding holding body 84 or 90 can be brought into the receiving space 102 through this opening 104 in an insertion direction 106 . Furthermore, the corresponding holding body 86, 90 can be exchanged through this first opening 104 in a push-out direction 108, which is a direction opposite to the push-in direction 106, out of the receiving space 102.

The receiving space 102 also has a second opening 110 ( Figures 3 , 5 , 6 ). In particular, the second opening 110 is connected to the first opening 104 .

The second opening 110 is designed in such a way that a holding body 86 or 90 positioned in the corresponding receiving space 102 cannot be inserted through it. A wall 112 of the corresponding receptacle 84, 88 is formed around the second opening 110, which wall is a barrier wall for the corresponding holding body 86, 90 to emerge in the extension direction 108 (cf. in particular figure 6 ).

The second opening 110 is designed in such a way that the corresponding neck 98, 100 can be positioned in it.

By pivoting the bracket 69, the corresponding receptacle 84, 88 can be positioned in such a way that the corresponding neck 98 or 100 lies in the second opening 110. In this position of the bracket 69, which is a locking position 114, the cover 64 can be (detachably) fixed to the roller housing 14 on the end wall 52 via the holding bodies 86, 90.

The receptacles 84, 88, together with the holding bodies 86, 90 and the bracket 69, form a locking device 115 for fixing the cover 64 to the roller housing 14.

The receiving space 102 is delimited in particular by an at least partially spherical wall. This enables a (supported) rotation of the corresponding receptacle 84 or 88 about the pivot axis 68 with the holding body 86 or 90 positioned in the receptacle space 102. The receptacle space 102 forms a socket, with relative rotation being possible by pivoting the bracket 69 about the pivot axis 68 to the roller housing 14 is possible.

In the locking position 114 of the bracket 69 ( Figures 1 to 6 ) this is pivoted relative to the cover 64 in such a way that when the holding bodies 86 and 90 are seated in the respective receiving spaces, the respective first neck 98 or 100 is seated in the second opening 110 and the corresponding blocking effect is thus achieved, which allows the cover 64 from the roller housing 14 locks; the cover 64 cannot be removed from the roller housing 14 in the extension direction 108 .

A recess 116 is formed on the outside 74 of the cover 64 and is adapted to the shape of the bracket 69 with its first area 78 , its second area 80 and its third area 82 . The recess 116 is designed as a channel; it forms a depression on the outside 74 of the cover 64.

In the locking position 14 of the pivotable bracket 69, the bracket 69 is positioned in the recess 116. The recess 116 is in particular designed in such a way that the bracket cannot protrude beyond it. In this way, a recessed arrangement of the bracket 69 in the locking position 114 can be achieved.

The bracket 69 also has a release position 118 ( Figures 7 to 12 ).

In the release position 118, the bracket 69 is pivoted with its first receptacle 84 and its second receptacle 88 such that the respective first opening 104 of the first receptacle 84 and the second receptacle 88 is in such a position that in the extension direction 108 the respective first holding body 86 or second holding body 90 can be immersed through the first opening 104 and can thus be exchanged from the corresponding receiving space 102 . As a result, the cover 64 can be removed from the roller housing 14 .

The release position 118 is a pivoting position relative to the locking position 114. For example, a pivoting angle between the locking position 114 and the release position 118 is approximately 90°.

In the release position 118 the bracket 69 projects transversely and in particular perpendicularly from the outside 74 of the cover 64 .

Inserting or replacing the cleaning roller 46 on the floor head 12 works as follows:
Starting from the locking position 114 of the bracket 69 ( Figures 1 to 6 ) the cover 64 is locked to the roller housing 14. The bracket 69 is arranged in a recessed manner in the recess 116 .

The respective holding bodies 86, 90 are positioned at their associated receptacles 84 and 88 in the respective receptacle space 102. The cover 84 covers the holding bodies 86, 90 on the outside.

The respective first neck 98 of the first holding body 86 and the second neck 100 of the second holding body 90 is positioned in the second opening 110 . The wall 112 blocks the respective holding body 86, 90 from emerging from the corresponding receiving space 102 in the extension direction 108.

The extension direction 108 is in particular at least approximately parallel to the axis of rotation 50.

The cleaning roller 46 is rotatably supported on the cover 64 via the pivot bearing 66 .

To remove the cleaning roller 46 from the roller receptacle 42, the bracket 69 is pivoted from the locking position 114 into the release position 118. It is thereby taken out of the recess 116 and pivoted, for example, through a pivoting angle of 90° ( Figures 7 to 12 ).

By pivoting the bracket 69, the first receptacle 84 and the second receptacle 88 are also pivoted with the bracket. As a result, the openings 104, 110 are also pivoted.

In the release position 118, the respective first openings 104 of the first receptacle 84 and the second receptacle 88 are then positioned in such a way that the holding bodies 86 and 90 can be exchanged through them in the extension direction 108. By rotating the bracket 69, the wall 112 no longer forms a barrier wall.

The cover 64 can thereby be removed from the roller housing 14; the receptacles 84, 88 can be detached from the associated holding bodies 86, 90 in relation to the extension direction 108; the holding bodies 86, 90 can be exchanged from the associated receiving spaces.

The cover 64 can also be detached from the cleaning roller 46 and can be removed as a whole from the roller housing 14 (cf figure 12 ).

In particular, the cover 84 and the cleaning roller 46 are loosely connected to one another.

After the cover 64 has been removed, the cleaning roller 46 can then be pushed out of the roller receptacle 42 .

To insert a new cleaning roller, this is inserted into the (empty) roller receptacle 42 and brought into contact with the pivot bearing 58 via its counter-element 60 .

The pivotable bracket 69 is brought into its release position 118 on the cover 64 . It is placed on the roller housing 14. The first opening 104 of the respective first receptacle 84, 88 is positioned such that the associated first holding body 86 or the second holding body 90 is immersed in the associated receiving space 102.

After the immersion process, the bracket 69 is pivoted into its locked position 114 . This rotates the first socket 84 and the second socket 88, thereby pivoting the second opening 110 so that the corresponding first neck 98 and second neck 100 are positioned thereon. The wall 112 then acts as a blocking element.

In principle, it is possible for the locking position 114 to be additionally secured. For example, spring loading of the bracket 69 can be provided, and a spring force must be overcome in order to bring the bracket 69 from the locking position 114 into the release position 118 .

It is also possible, for example, that the pivot bearing 92 is so "sluggish" that an increased expenditure of force is necessary in order to reach the release position 118 from the locking position 114 .

In another embodiment ( Figures 13 to 16 ) it is provided that the cleaning roller 46' can be locked axially with a cover 120. Otherwise, the cleaning machine is designed in the same way as the cleaning machine 10 and the same reference numbers are used for the same elements.

The cleaning roller 46' is basically of the same design as the cleaning roller 46. It also includes a pin 122 on a side facing away from the counter-element 60.

A slide 124 is arranged on the cover 120, which together with the pin 122 forms a locking device 126 for the axial locking of the cover 120 with the cleaning roller 46'.

The slider 124 has a recess 128 into which the pin 122 is immersed. In a locking position (cf figure 16 ) the pin 122 is immersed in the recess 128. The slider 124 is in such a displacement position that it is blocked for the pin 122 to emerge from the recess 128 . As a result, the cleaning roller 46' is axially fixed (in a direction parallel to the axis of rotation 50) to the cover 120.

This locked position can be released by moving the slide 124 . The lock is then released and the pin 122 can emerge from the recess 128 on the cover 120 . This allows the cleaning roller 46' to be detached from the cover 120.

With regard to the fixing and locking of the cover 120 to the roller housing 14, this embodiment functions in the same way as described above.

In the embodiment according to Figures 13 to 16 the cleaning roller 46' is not mounted loosely on the cover 120, but an axial locking is possible.

In order to insert the cleaning roller 46' into the corresponding roller receptacle 42, the cleaning roller 46' is first locked to the cover 120 by the pin 122 is brought into the recess 128 and the slide 124 is then brought into its locking position.

This establishes an axial connection between the cover 120 and the cleaning roller 46'.

This axial connection is such that the cleaning roller 46 ′ can be rotated relative to the cover 120 . A corresponding rotary bearing 130 is arranged on the cover 120 for this purpose.

The cleaning roller 46' can then be pushed into the roller receptacle 42 in this combination.

The corresponding bracket 69 on the cover 120 is in its release position 118 and the holding bodies 86, 90 can then be immersed in their respective receiving spaces 102. Locking is achieved by pivoting the bracket 69 into its locking position 114 .

The reverse procedure is followed to detach the cleaning roller 46' from the roller housing 14.

The combination of cover 120 and cleaning roller 46', which are axially connected to one another, is removed from the roller housing 14 (cf figure 14 ). After the cover 120 has been removed from the cleaning roller 46', it is then released by corresponding displacement of the slide 124 from its locking position.
