The invention has for its object to provide a cleaning machine of the type mentioned, in which an exchange of the cleaning roller on the roller housing is possible in a simple manner.

In the cleaning machine mentioned at the outset, this object is achieved in that at least one convex holding body is arranged on the roller housing, that a pivotable bracket is arranged on the cover, and that at least one receptacle for the at least one is arranged on the pivotable bracket Holding body is arranged, 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, the holding body emerges from the assigned 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 tools. The number of components required is minimized.

The result is simple operability for the user; by a

Swiveling the pivotable bracket with the at least one receptacle can bring the lid from the locking position into a release position or vice versa from the release position into a locking position.

The measures on the roller housing for fixing the cover can be carried out in a structurally simple manner. The locking can only be achieved with the at least one convex holding body. It is expedient if the at least one convex holding body is designed as a holding ball. In this way, locking can 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 holding ball arranged on a receptacle.

It is expedient 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 spherical shape in the receiving space. Depending on the position of the receptacle, an immersion or immersion can be achieved or such an immersion can be blocked.

The recording space advantageously 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 locking position.

It is very particularly advantageous if the receiving space has a first opening and a second opening, the holding body being able to be passed through the first opening and the holding body not being able to be passed through the second opening. The relative position of the first opening and the second opening to the roller housing is predetermined by a pivoting position of the pivotable bracket. The holding body can then easily be brought into the associated receiving space through the first opening. By swiveling the bracket, the receiving space with the second opening can be positioned in such a way that an immersion of the holding body is blocked.

In particular, the holding body is seated on a neck, the neck being positioned in the second opening in the locking position. The holding body has larger width dimensions than the neck. The neck represents a kind of ball neck. By positioning in the second opening you can block an immersion of the holding body from the corresponding receiving space in a simple manner. This blocking can be easily removed by swiveling the corresponding holder.

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 easy to block the corresponding holding body from emerging from the associated receiving space.

It is expedient 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 enables the cover to be locked to the roller housing at at least two points. A good closure of the roller holder on the roller housing can be achieved in this way.

In particular, a pivot bearing for pivoting the pivotable bracket between the first receptacle and the second receptacle is arranged. This results in a compact structure for the roller housing and the cover. The number of components required 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 help a release position can be easily achieved by pivoting into this transverse position.

It is expedient for the pivotable bracket to be oriented at least approximately parallel to the cover in the locking position. As a result, it protrudes minimally or not beyond 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 recessed on the cover in the locking position.

It is expedient if an immersion direction and / or an immersion 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 construction. It is also easy to use.

In one embodiment, a pivot 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 °. In this way, a transition between the release position and the locking position and vice versa can be achieved in a simple manner by pivoting the swivel bracket.

In one embodiment, the pivotable bracket has a first area on which a first receptacle is arranged, and has a second area on which a second receptacle is arranged, and has a third area which is between the first area and the second Area. For example, you can use the third area Design the grip area for gripping the bracket for a swiveling movement. The result is a compact structure with optimized use of space.

In particular, the third area is designed as an arch. This makes it easy to grip. There is an optimized use of space on the lid.

It is also advantageous if a swivel 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 a rotary drive of the at least one cleaning roller, the drive motor in particular being arranged on the roller housing. In principle, it is also possible for a displacement of the operator of the roller housing over a surface to be cleaned to drive a rotary movement of the at least one cleaning roller.

It is favorable if a bearing for the at least one cleaning roller for rotatably mounting the at least one cleaning roller is arranged on the cover. 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 bearing for the at least one cleaning roller can be achieved in the roller housing.

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

It is expedient if the cover can be completely removed from the roller housing and in particular the at least one cleaning roller from the cover is solvable. This makes it easy to replace a cleaning roller.

In one embodiment, the roller housing has an end wall assigned to the roller holder, 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 with the roller housing.

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.

The result is a compact structure. The cover can be easily locked or removed from the roller housing.

It is expedient if the roller receptacle has an opening to an envelope plane (to a lower envelope plane) of the roller housing. This opening is in particular a sucking opening or suction opening 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 therefore possible, if the cover is locked with 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 holder. Further the cleaning roller can be inserted over the lid. This results in easy removal or automatic alignment. This makes it easier to remove or insert the cleaning roller.

It is expedient if the locking device is designed for an axial locking between the cover and the at least one cleaning roller and, in particular, enables rotation between the at least one cleaning roller and the cover. This results in simple 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 an axial locking between the cover and the at least upon locking engagement of the slide on the pin there is a cleaning roller. The axial locking allows in particular a rotation of the at least one cleaning roller relative to the cover. In this way, axial locking can be achieved in a simple manner, which can be released in a simple manner.

The at least one cleaning roller is, for example, a brush roller and / or textile roller. It is possible that a textile trim and brush trim are 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 a carpet brush vacuum cleaner.

It is then favorable if at least one sucking opening is formed on the roller holder. Dirt can be sucked in through these.

An embodiment of a cleaning machine 10 according to the invention is a brush suction machine (carpet brush vacuum cleaner), which is shown in perspective view in FIG. 1.

The cleaning machine 10 comprises a bottom head 12 with a roller housing 14. The bottom head 12 can be supported on a surface 16 to be cleaned (see FIG. 2) by means of a wheel device 18.

In one exemplary embodiment, the wheel device 18 comprises wheels 20 with in particular a left rear wheel and a right rear wheel. The wheels 20 are arranged in the region 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 bottom head.

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

In one exemplary embodiment, the holding rod device 24 comprises a single holding rod 28. A housing 30 is arranged on this holding rod 28. A suction blower device 32 is positioned in the housing 30. The suction blower device 32 comprises a blower motor, which is in particular an electric motor, and a corresponding blower device with one or more impellers.

The housing 30 or the holding rod device 24 is connected to the floor head 12 and in particular is pivotably connected such that the holding bar 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 mouth 34 is formed on the roller housing 14. This has a fluid-effective 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 connected to the suction blower device 32 in a fluid-effective connection with a particularly flexible suction hose 38.

A holder 40 for the suction pipe 36 is arranged on the housing 30.

Via the suction pipe 36, when it is removed from the holder 40, a user can carry out suction separately from the suction mouth 34.

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

The roller holder 42 is open at the suction mouth 34. Otherwise it is closed.

The roller holder 42 (also compare, for example, FIG. 12) serves to hold a cleaning roller 46.

In one exemplary embodiment of a brush suction machine, the cleaning roller 46 is a brush roller with a bristle trim 48. The bristle trim 48 is in particular arranged such 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, FIGS. 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 placed on it and supported by the wheel device.

An end wall 52 on the roller housing 14 is assigned to the roller holder 42 (compare FIGS. 3, 8, 12).

An opening 54 is formed in this end wall 52. The opening 54 is an opening of the roller holder 52.

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

A wall 56, which is closed, is also assigned to the roller holder 42 opposite the opening 54. The wall 56 is a side wall of the roller housing 14. A rotary bearing 58 for the cleaning roller 46 is arranged on this wall 56. The cleaning roller 46 has a counter element 60 for this rotary bearing 58. With the counter element 60, in particular the cleaning roller 46 can be pushed onto the rotary bearing 58.

In one embodiment, it is provided that a drive motor 62 (cf. FIG. 2) for the rotary movement of the cleaning roller 46 is arranged in the roller housing 14. The drive motor 62 acts, for example, on the cleaning roller 46 via a belt drive and drives it in its rotational movement. For example, the drive motor 62 acts on the rotary bearing 58 in order to effect a corresponding rotation, and the cleaning roller 46 can be connected in a rotationally fixed manner to the rotary bearing 58 via the counter element 60.

A cover 64 is provided to close the opening 54. A rotary bearing 66 is arranged on the cover 64. When the opening 54 is closed with the cover 64, the rotary bearing 66 rotatably supports the cleaning roller 46 on the cover 64 about the axis of rotation 50.

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

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

A bracket 69 is pivotably mounted on the cover 64 about a pivot axis 68.

The pivot axis 68 is oriented transversely and in particular vertically with respect to the axis of rotation 50. Relative to a lower envelope plane 70 of the roller housing 14 (cf. FIG. 2), the lower envelope plane 70 in particular referring to the roller housing 14 without a wheel device 18, and which is aligned at least approximately parallel to the surface 16 to be cleaned if If the bottom head 12 is properly positioned with respect to this, the pivot axis 68 lies at an acute angle 72 (see FIG. 2). This acute angle is, for example, on the order of approximately 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, FIG. 4) a first area 78 and a second area 80 spaced apart from the first area 78. The first area 78 and the second area 80 are at least approximately rectilinear. 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 on the first region 78.

A second receptacle 88 for a second convex holding body 90 of the roller housing 14 sits 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 the latter.

The bracket 69 is pivotally held on the cover 64 via a pivot bearing 92. The pivot bearing 92 comprises a first bearing area 94, which is seated on the first area 78, and a second bearing area 96, which is seated on the second area 80 of the bracket 69. The first storage area 94 and the second storage 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 predetermined by the pivot axis 68.

The first holding body 86 (compare FIGS. 6, 11, 14) is convex and in particular is designed as a ball. It sits on the end wall 52 via a first neck 98. The second holding body 90 is likewise convex and in particular is designed as a holding ball. It sits at a distance from the first holding body 86 on the end wall 52 via a second neck 100. The opening 54 lies between the first holding body 86 and the second holding body 90. The first receptacle 84 and the second receptacle 88 each comprise a receptacle space 102 for the associated holding body 86 or 90 (see FIGS. 5, 6, 8, 10, 11).

The receiving space 102 has a first opening 104 (FIGS. 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, through this first opening 104, the corresponding holding body 86, 90 can be exchanged from the receiving space 102 in an extension direction 108, which is a direction opposite to the insertion direction 106.

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

The second opening 110 is designed such that a holding body 86 or 90 positioned in the corresponding receiving space 102 cannot be penetrated through it. Around the second opening 110, a wall 112 of the corresponding receptacle 84, 88 is formed, which is a barrier wall for the immersion of the corresponding holding body 86, 90 in the extension direction 108 (compare in particular FIG. 6).

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

By pivoting the bracket 69, the corresponding receptacle 84, 88 can be positioned such 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 (detachable) can be fixed with 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 receiving space 102. The receiving space 102 forms a pan, with a relative rotation 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 (FIGS. 1 to 6), it is pivoted relative to the cover 64 in such a way that, in the case of holding bodies 86 and 90 seated in the respective receiving spaces, the respective first neck 98 or

100 sits in the second opening 110 and thus the corresponding locking effect is achieved, which blocks removal of the cover 64 from the roller housing 14; The cover 64 cannot be removed from the roller housing 14 in the extension direction 108.

On the cover 64, a recess 116 is formed on the outside 74, which 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 groove; 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 such that the bracket cannot protrude beyond it. A recess arrangement of the bracket 69 in the locking position 114 can thus 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 Extending direction 108 of 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 swivel position to the locking position 114. For example, a swivel angle between the locking position 114 and the release position 118 is approximately 90 °.

In the release position 118, the bracket 69 stands transversely and in particular vertically away 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 (FIGS. 1 to 6), the cover 64 is locked to the roller housing 14. The bracket 69 is arranged recessed in the recess 116.

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

The respective first neck 98 of the first holding body 86 and the second neck 100 of the second holding body 90 are 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 holder 42, the bracket 69 is pivoted from the locking position 114 into the release position 118. It is removed from the recess 116 and pivoted, for example, by a pivoting angle of 90 ° (FIGS. 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.

The respective first opening 104 of the first receptacle 84 and the second receptacle 88 are then positioned in the release position 118 such 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 with respect 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 (see FIG. 12).

In particular, the cover 84 and the cleaning roller 46 are loosely connected to one another. After removing the cover 64, the cleaning roller 46 can then be pushed out of the roller holder 42.

To insert a new cleaning roller, it is inserted into the (empty) roller holder 42 and brought into contact with the rotary 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 locking position 114. As a result, the first receptacle 84 and the second receptacle 88 are rotated and the second opening 110 is pivoted such that the corresponding first neck 98 and second neck 100 are positioned on it. The wall 112 then acts as a blocking element.

It is fundamentally 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.

For example, it is also possible for the pivot bearing 92 to be “difficult to move” in such a way that an increased expenditure of force is necessary in order to reach the release position 118 from the locking position 114.

In a further exemplary embodiment (FIGS. 13 to 16), it is provided that the cleaning roller 46 'can be axially locked with a cover 120. Otherwise, the cleaning machine is of the same design as the cleaning machine 10 and the same reference numerals are used for the same elements.

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

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

The slide 124 has a recess 128 in which the pin 122 is immersed. In a locking position (see FIG. 16), the pin 122 is immersed in the recess 128. The slide 124 is in such a displacement position that the pin 122 is prevented from emerging 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 locking position can be released by moving the slide 124. The lock is released and the pin 122 can emerge from the recess 128 on the cover 120. As a result, the cleaning roller 46 ′ can be detached from the cover 120.

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

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

To insert the cleaning roller 46 'into the corresponding roller holder 42, the cleaning roller 46' is first locked with the cover 120, in which the pin 122 is brought into the recess 128 and the slide 124 is then brought into its locking position.

This creates 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. For this purpose, a corresponding pivot bearing 130 is arranged on the cover 120.

The cleaning roller 46 'can then be used in this combination

Slide roller mount 42.

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 used 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 roller housing 14 (compare FIG. 14). After the cover 120 has been removed from the cleaning roller 46 ', it is then released from its locking position by a corresponding displacement of the slide 124. LIST OF REFERENCE NUMBERS
