The sweeping machine is provided with a footrest area in the area of ​​the rear wheel arrangement arranged on the chassis, wherein, starting from the sweeping machine being placed on the base surface as specified, the sweeping machine can be placed in a parking position as a whole off the base surface by the operator stepping on the footrest while being supported on the base surface by the rear wheel arrangement. Summary of the invention

[0009] The object of the present invention is to provide a sweeping machine of the type mentioned at the outset which has advantageous operating properties.

[0010] In the sweeper mentioned at the outset, this object is achieved according to the invention in that a placement device is provided, which has a placement surface for one or more objects and is held by a chassis, wherein the placement surface is parallel to the placement plane or is inclined at an angle of up to 10° relative to the placement plane.

[0011] During the cleaning operation of the sweeper, one or more objects, such as buckets, can be carried along on the placement surface.

[0012] Furthermore, when the cleaning machine is stored, one or more objects can be positioned on the cleaning machine above the placement surface.

[0013] Since the placement surface is inclined parallel to the placement plane or at a small acute angle of at most 10° relative to the placement plane, the objects are prevented to a great extent from sliding off the placement plane.

[0014] In principle, it is possible that the placement surface itself is flat or that the placement surface advantageously has a flat envelope. For example, the flat envelope is formed on the anti-slip device. Usually, in the case of larger objects, such as buckets, the corresponding objects are supported on the placement device via elements forming a flat envelope.

[0015] Advantageously, at least one of the following features is provided:

[0016] - the placement surface has a width of at least 20 cm in the width direction, wherein the width direction is oriented perpendicularly to the direction of travel of the sweeper;

[0017] - the placement surface has a length of at least 20 cm in the longitudinal direction, wherein the longitudinal direction is oriented parallel to the direction of travel of the sweeper;

[0018] - The mask should be placed at least 400 cm 2 and in particular at least 500 cm 2 Surface area;

[0019] - the placement surface is arranged and constructed such that, with respect to a height direction oriented perpendicularly to the placement plane, objects can be placed on the placement surface from above and, with respect to the height direction, the objects are supported downward by the placement surface;

[0020] - The placement surface is continuous;

[0021] - The placement surface is assigned at least one fixing recess.

[0022] This results in a correspondingly large placement surface, on which, for example, a 10-liter household bucket or a 20-liter construction bucket can also be placed. In a specific embodiment, the surface area of ​​the placement surface is approximately 550 cm 2 and 900 cm 2 .

[0023] By corresponding placement surface, can support downwards and make article be taken along and advance in the sweeper travel operation (no matter whether carry out cleaning operation).In addition, when sweeper is parked in the storage space, when parked on the placement plane, can realize the positioning of article on the placement surface.

[0024] The continuous placement surface results in an optimized use of space, in order to be able to place buckets, for example.

[0025] If the placement surface is assigned at least one fixing recess, the placed objects can be fixed via a quick-release device or a tensioning belt.

[0026] Advantageously, at least one of the following features is provided:

[0027] - the axis of rotation of at least one main sweeping roller is transverse and in particular perpendicular to the direction of advancement of the sweeping machine;

[0028] - the rotation axis of at least one main sweeping roller is parallel to the wheel axis of the rear wheel arrangement;

[0029] - the push-type bow is arranged on the chassis in a manner so as to be pivotable about a pivot axis, wherein the pivot axis is oriented parallel to the axis of rotation of the at least one main sweeping roller;

[0030] - the swivel axis of the push bow is transversely and in particular perpendicular to the direction of travel of the sweeper;

[0031] - the rotation axis of at least one main sweeping roller is parallel to the placement plane;

[0032] The wheel axis of the rear wheel arrangement is oriented parallel to the placement plane.

[0033] This results in a design that is simple in design and correspondingly simple in operability.

[0034] More particularly advantageously, the placement surface is provided with an anti-skid device. Thus, when, for example, a floor surface with an inclination should be cleaned, articles are difficult to slide off the placement surface.

[0035] In an embodiment of a simple design, the placement device has parallel and spaced-apart webs. The parallel and spaced-apart webs define an envelope and in particular a flat envelope. The webs are designed so that they have an anti-slip effect.

[0036] In particular, at least one of the following features is then provided:

[0037] - the web is oriented transversely and in particular perpendicularly to the wheel axis of the rear wheel arrangement;

[0038] - the webs are oriented transversely and in particular perpendicularly to the axis of rotation of the at least one main sweeping roller;

[0039] - the blades are oriented parallel to the direction of travel of the sweeper;

[0040] - the web is oriented parallel to the placement plane or inclined at most by 10° relative to the placement plane;

[0041] The tab is at least partially made of an anti-slip material, for example a rubber material.

[0042] This results in a construction which is simple in design.

[0043] It is also possible to provide other types of anti-slip devices, such as anti-slip mats or the like.

[0044] Advantageously, the placement surface is provided with a wall on which at least one fixing element and / or at least one receiving recess is arranged. The "load" can then be fixed on the placement surface, for example via a quick-release device or a tensioning belt. The fixing element can, for example, be in the form of a fixing recess or a fixing eyelet. Small objects such as screwdrivers or the like can be held in the receiving recess.

[0045] Advantageously, the placement surface is delimited by edge walls. This provides a wall on which one or more fastening recesses can be arranged. When the edge walls extend upward beyond the placement surface, the edge walls can also prevent objects from falling off the placement surface in the region of the corresponding edge walls. For example, it may be advantageous if the sweeper is operated on a ground surface that is inclined relative to the direction of gravity.

[0046] Advantageously, at least one of the following features is provided:

[0047] - the edge wall comprises a handle, in particular a handle for a disposal container;

[0048] - The edge wall is open towards the front side of the sweeper;

[0049] - at least one receiving opening is arranged on the edge wall;

[0050] - at least one fixing eyelet and / or at least one fixing recess is arranged on the edge wall;

[0051] The edge wall projects upward from the placement surface away from the placement plane at least in a partial region in a height direction perpendicular to the placement plane and / or in at least a partial region in a height direction towards the placement plane.

[0052] When the edge wall comprises a handle, which is in particular a handle of a cleaning material container, a design that is simpler in design is obtained, thereby making it possible to keep the number of components low and to obtain simplified manufacturability.

[0053] If the edge wall is open toward the front side of the sweeping machine, liquids that have accumulated on the placement surface can be drained away in a simple manner or their accumulation can be prevented.

[0054] At least one receiving opening for a tool or the like can be positioned in a simple manner on the edge wall.

[0055] The “load” can be fixed on the placement surface in an advantageous manner by means of fixing eyes or fixing recesses in the edge wall.

[0056] It can be provided that the edge wall at least in some areas extends upwards away from the placement surface in a height direction perpendicular to the placement plane and / or extends downwards. Depending on the use of the sweeping machine, an optimized design is thus obtained.

[0057] In particular, the placement surface is spaced apart from the placement plane in a height direction perpendicular to the placement plane, and in particular has at least one of the following features:

[0058] - the placement surface is located above at least one main cleaning roller in height direction;

[0059] - the placement surface is located above at least one side broom in height direction;

[0060] - the placement surface is located above the swing axis of the push-type bow in the height direction, or is located below the swing axis of the push-type bow in the height direction;

[0061] - The placement surface is located above the rear wheel device in terms of height;

[0062] - The placement surface is located at the highest point of the sweeper in terms of height and apart from the push bow.

[0063] This results in simple operability.

[0064] In one embodiment, the placing surface is fixedly connected with the chassis. For example, the placing surface is arranged on the cleaning material container or is arranged on the removable housing element.

[0065] In one embodiment, the placement surface is arranged on the cleaning material container, and has at least one of the following characteristics:

[0066] - the placement surface is formed on the wall of the disposal container;

[0067] - The edge wall of the placement surface is formed in the disposal container.

[0068] Then, when the cleaning material container is properly arranged on the chassis of the sweeping machine, the cleaning material container can be used to transport one or more objects on the placement surface.

[0069] For example, an edge wall which delimits the placement surface on the cleaning material container can thereby also be realized in a simple manner.

[0070] It is also advantageous that the handle of the sweeping material container delimits the placement surface, thereby achieving optimized space utilization and simplifying the manufacturability of the sweeping machine.

[0071] In one embodiment, a suction fan device is provided, by means of which the interior of the cleaning material container can be loaded with a negative pressure flow, and a filter device is provided for the negative pressure flow. In principle, during the cleaning operation, at least one main cleaning roller of the sweeper stirs up dust, which then enters the surroundings of the sweeper. This "dust loading" of the surroundings of the sweeper can be reduced by the suction fan device. Usually, the main task of the suction fan device is to keep the dust load on the surroundings low, and it is not the main task of the suction fan device to directly perform dust extraction of the surface to be cleaned.

[0072] In one embodiment, the placement surface is arranged or formed on a housing, wherein the housing is a housing of a suction fan device and / or a housing for a filter device. As a result, the components of the sweeping machine can be utilized in an optimized manner. If a suction fan device is provided, it is in principle advantageous to load the sweeping material container via a negative pressure flow above the upper side of the sweeping material container, wherein the upper side is away from the placement plane. Therefore, one or more openings are arranged on the upper side, which are fluidically connected to the suction fan device via the openings, and the negative pressure flow is coupled in via the openings. As a result, components of the sweeping machine are obtained that are arranged above the sweeping material container with respect to a height direction perpendicular to the placement plane. Among these components is a housing, which is a housing of a suction fan device and / or a housing for a filter device. As a result, the corresponding housing can be optimized for transporting one or more items via a correspondingly constructed placement surface.

[0073] In one embodiment, the placement surface is arranged on the openable cover of the housing. For example, the housing is a filter box and is formed with a lid of the placement surface thereon, and this lid is a filter that can be placed into a filter device after opening or a lid that can remove the filter from the filter box.

[0074] Advantageously, at least one fastening recess is arranged on the housing. For example, a hook of a quick-release tensioning device can be inserted into the fastening recess, or a tensioning belt can be guided through it. As a result, components of the housing can be used to fasten the "load" on the placement surface with little effort in terms of production technology and design structure.

[0075] Advantageously, at least one of the following features is provided:

[0076] - The cleaning material container is arranged between the placement surface and the placement plane;

[0077] - the cleaning material container is arranged between the placement surface and the suction fan device;

[0078] - The sweeping material container is arranged between the placement surface and the filter device.

[0079] This results in an optimized utilization of space.

[0080] Furthermore, it is particularly advantageous if at least one of the following features is provided:

[0081] - the placement surface is arranged on a bridge which is positioned in height direction above the disposal container;

[0082] The filter device is arranged on a bridge which is positioned in height above the sweeping material container.

[0083] As mentioned above, it is meaningful that one or more openings, through which the negative pressure flow is coupled into the cleaning material container, are located on the upper side of the cleaning material container facing away from the placement plane. It is again advantageous to provide a bridge through which the negative pressure flow is conveyed to the cleaning material container. The bridge is then arranged above the cleaning material container in a height direction perpendicular to the placement plane, and a meaningful arrangement is obtained for carrying one or more objects with the cleaning machine.

[0084] In one embodiment, the filter device is arranged on a bridge which is respectively positioned in height direction above the cleaning material container.

[0085] In particular, the sweeping machine is designed as a hand-guided sweeping machine, which an operator can guide via a push bow over the floor surface to be cleaned.

[0086] In an advantageous embodiment, a height adjustment device is provided, via which the height position of the rotation axis of the at least one main sweeping roller relative to the placement plane can be adjusted, and the sweeping machine is provided with a handle, which can be swung relative to the chassis, the handle is mechanically coupled to the height adjustment device, and via which the operator can adjust the height position of the rotation axis relative to the placement plane in a fixed manner. The handle has an end position in which the at least one main sweeping roller is spaced apart from the placement plane.

[0087] The bristles of at least one main cleaning roller are protected by the spacing that occurs in the mentioned end positions. In the corresponding end positions, the bristles are not subjected to mechanical loads due to contact with the surface. This in turn allows the cleaning machine to be parked on the ground with the placement plane without mechanical loads on the at least one main cleaning roller. This results in a prolonged service life. Thus, in a corresponding parking position of the cleaning machine, in which the cleaning machine is placed on the ground via the placement plane, the placement surface can be used as a storage space for one or more objects.

[0088] In particular, according to the present invention, a cleaning material container having a placement surface is used for placing objects. BRIEF DESCRIPTION OF THE DRAWINGS

[0098] exist Figures 1 to 5 A first embodiment of a sweeping machine according to the invention, shown in Figure 1 and designated 10, comprises a chassis 12. The chassis 12 forms the body or base of the sweeping machine 10 and holds (directly or indirectly) the components of the sweeping machine 10. The chassis 12 ensures the mechanical stability of the sweeping machine 10 and holds the components of the sweeping machine.

[0099] The chassis 12 has a front end 14 and a rear end 16. A longitudinal axis 18 of the chassis 12 (and thus the sweeping machine 10) extends between the front end 14 and the rear end 16.

[0100] The sweeper 10 is placed on a surface 24 to be cleaned (see FIG. 2 ) in a movable manner via the rear wheel device 20 and the front wheel device 22. Figure 3 The rear wheel arrangement 20 and the front wheel arrangement 22 define a placement plane 26 for the sweeping machine 10 on the surface 24 to be cleaned. If the surface 24 to be cleaned is flat, the placement plane 26 coincides with the surface to be cleaned.

[0101] The rear wheel arrangement 20 is arranged in the region of the rear end 16 on the chassis 12. The rear wheel arrangement 20 has a right rear wheel 30 and a left rear wheel 32 with respect to the advancing direction 28 of the sweeping machine 10. The right rear wheel 30 and the left rear wheel 32 are spaced apart from one another in a transverse direction 34. The transverse direction 34 is perpendicular to the longitudinal axis 18 and parallel to the resting plane 26.

[0102] The right rear wheel 30 and the left rear wheel 32 are positioned on the chassis 12 in a manner that they can rotate about a common wheel axis 36. The wheel axis 36 is parallel to the transverse direction 34. The wheel axis is perpendicular to the longitudinal axis 18. The wheel axis is perpendicular to the direction of travel 28. The wheel axis 36 is parallel to the resting plane 26.

[0103] The right rear wheel 30 and the left rear wheel 32 are arranged laterally on the chassis 12. In one embodiment, they extend to the rear end 16 (see Figure 1 ).

[0104] In one embodiment, the front wheel arrangement 22 is a roller or comprises a roller 38 , in particular a steering wheel. The front wheel arrangement 22 with the (at least one) roller 38 is arranged in the region of the front end 14 .

[0105] In one embodiment, the roller 38 is located on the center plane 40 of the chassis 12 (see Figure 2). The center plane 40 is perpendicular to the placement plane 26, the transverse direction 34 is perpendicular to the center plane 40, and the longitudinal axis 18 is located in the center plane 40. The center plane 40 is a plane centered between the right rear wheel 30 and the left rear wheel 32.

[0106] The roller 38 can rotate about a roller axis. In the advancing direction 28 of the sweeper 10, the roller axis is parallel to the wheel axis 36. The wheel axis 36 is a fixed axis with respect to the chassis 12. When the roller is configured as a steering roller, the orientation of the roller axis relative to the chassis 12 depends on the position of the roller 38.

[0107] The roller axis of the roller 38 is parallel to the support plane 26 .

[0108] The sweeping machine 10 comprises a push bow 42 which is arranged on the chassis in the region of the rear end 16 and in particular in the region of the rear wheel arrangement 20. Via the push bow 42, an operator standing on the floor 24 to be cleaned can guide and in particular push the sweeping machine on the floor to be cleaned.

[0109] In one embodiment, no motorized travel drive is provided for the sweeping machine 10 and the travel motion is driven by the operator (via operator force).

[0110] In one embodiment, the push-type bow 42 can be pivoted relative to the chassis 12 about a pivot axis 44. In this case, the defined pivot position of the push-type bow 42 relative to the chassis 12 can be fixed steplessly or in stages. As a result, on the one hand, the push-type bow 42 can be pivoted for receiving the sweeper 10, so that the height of the sweeper 10 in a height direction 46 perpendicular to the placement plane 26 is minimized and, for example, does not protrude beyond the upper side of the sweeper 10.

[0111] Due to the pivotability of the push bow 42 about the pivot axis 44 , the height of the sweeping machine 10 can also be adjusted to the operator during sweeping operation.

[0112] The pivot axis 44 is parallel to the support plane 26 and is perpendicular to the center plane 40 . The pivot axis 44 is perpendicular to the longitudinal axis 18 of the chassis 12 .

[0113] In one exemplary embodiment, a corresponding pivot bearing for pivotably connecting the push bow 42 to the chassis 12 is arranged such that the pivot axis 44 is located above the wheel axis 36 of the rear wheel arrangement 20 in the height direction 46 .

[0114] In one embodiment, the push bow comprises a first rod area 48 and a spaced-apart second rod area 50 , wherein the first rod area is connected to the chassis 12 in a pivotable manner in the area of ​​the left rear wheel 32 and the second rod area is connected to the chassis 12 in a pivotable manner in the area of ​​the right rear wheel 30 .

[0115] The first rod area 48 and the second rod area 50 are connected to the chassis 12 via the distal end area. A third rod area 52 is provided, which connects the first rod area 48 and the second rod area 50 to each other at the proximal end area. The third rod area 52 is the main gripping area for the operator of the sweeping machine 10 to guide it on the surface 24 to be cleaned.

[0116] A main cleaning roller 54 is arranged on the chassis 12 and can rotate about a rotation axis 56. The main cleaning roller 54 comprises a cylindrical carrier 58 on which a plurality of bristles are arranged.

[0117] The rotation axis 56 is parallel to the resting plane 26. The rotation axis is parallel to the wheel axis 36. The rotation axis is parallel to the swivel axis 44. The rotation axis is perpendicular to the center plane 40. The rotation axis is parallel to the transverse direction 34. The rotation axis 56 is perpendicular to the longitudinal axis 18. The rotation axis is perpendicular to the advancing direction 28.

[0118] During the cleaning operation of the cleaning machine 10, the bristles of the main cleaning roller 54 act on the surface 24 to be cleaned (see Figure 5 ; Figure 5 1 shows a position of the main cleaning roller 54 in which the main cleaning roller touches the surface 24 to be cleaned with its bristles and thereby exerts a mechanical action on the surface to be cleaned. This causes the bristles to produce Figure 5 For illustration purposes, corresponding deformations are not shown).

[0119] The main sweeping roller 54 is arranged in the region of the rear end 16 of the chassis 12 between the left rear wheel 32 and the right rear wheel 30 .

[0120] A pivot device 60 is positioned on the chassis 12 via a pivot bearing 62 . The pivot bearing 62 defines an axis of rotation 64 .

[0121] The rotation axis 64 is parallel to the resting plane 26. The rotation axis is parallel to the rotation axis 56. The rotation axis is perpendicular to the center plane 40. The rotation axis is parallel to the wheel axis 36. The rotation axis is parallel to the transverse direction 34. The rotation axis is perpendicular to the longitudinal axis 18.

[0122] The swivel device 60 has a first region 66, a second region 68 and a third region 70. The second region 68 is located between the first region 66 and the third region 70. The swivel device 60 is held on the chassis 12 via the second region 68 by means of the rotary bearing 62.

[0123] In a first region, the main sweeping roller 54 is held on a pivoting device 60 via corresponding roller bearings so as to be rotatable about the axis of rotation 56 .

[0124] Depending on the rotational position of the oscillating device 60 about the rotational axis 64 , the rotational axis 56 of the main sweeping roller 54 is located at different height positions (in the height direction 46 ) relative to the support plane 26 . This will be explained in more detail below.

[0125] A height adjustment device 72 is formed by the pivoting device 60 , by means of which the height position of the main sweeping roller 54 relative to the support plane 26 can be adjusted depending on the rotational position of the pivoting device 60 about the rotational axis 64 .

[0126] It can be provided that a guide device is assigned to the pivoting device 60 in order to guide the pivoting device 60 relative to the chassis 12 and thus the main cleaning roller 54 .

[0127] In one embodiment, the oscillating device includes spaced oscillating elements that are connected to each other and are connected to each other, for example, at the third region 70. Between the spaced oscillating elements, the main sweeping roller 54 is positioned at the first region 66 on a corresponding rotary bearing for being rotatable about the axis of rotation 56.

[0128] The chassis 12 includes a first region 74 where the rear end 16 is located and a second region 76 immediately following the first region 74 on the longitudinal axis 18 and where the front end 14 is located.

[0129] A housing 78 is arranged on the first region 74, which has a housing interior 80 (see Figure 3 ). The height adjustment device 72 is arranged in the housing interior space 80 .

[0130] The housing 78 has a wall 82 as a boundary with the second region 76 .

[0131] In particular, a rotary bearing for the main sweeping roller 54, which is mounted so as to be rotatable about the axis of rotation 56, is also arranged in the housing interior 80. Furthermore, a pivoting device 60 having a rotary bearing 62 is also arranged in the housing interior 80.

[0132] A handle 84 is provided for the operator to adjust the height of the main sweeping roller 54 relative to the support plane 26. The handle 84 comprises a rod 86 which is rigidly connected to the third region 70 of the oscillating device 60; the handle 84 is mechanically coupled to the oscillating device 60 via the rod 86.

[0133] The handle 84 is thus rotatable or pivotable relative to the chassis 12 via the axis of rotation 64 .

[0134] A track device 88 is arranged on the housing 78. The track device is used to fix a specific rotational position or swing position of the handle 84 relative to the chassis 12. In addition, the track device also indicates to the operator which rotational position the handle 84 is in relative to the chassis 12. The determined rotational position in turn corresponds to the height position of the main cleaning roller 54 (with respect to the rotation axis 56) above the placement plane 26.

[0135] The track assembly 88 includes a circular track 90 having opposing circular track elements with gaps between the circular track elements, through which the rod 86 passes.

[0136] A positive locking element 92 is arranged on the rod 86 outside the housing interior 80. The positive locking element is used to fix the swing position (rotational position) of the handle 84 on the circular track 90 and thus also to fix the determined rotational position of the swing device 60 relative to the chassis 12.

[0137] Coupling elements 94 and in particular spaced-apart discrete elements 94 are arranged on the circular track 90. ​​These discrete elements correspond to the form-locking elements 92, so that in a determined discrete position, the form-locking elements 92 can lock with the cooperating elements 94 and thus prevent the handle 84 from being able to swing relative to the chassis 12. This in turn prevents the swing device 60 from being able to swing around the axis of rotation 64. This in turn means that the determined height position of the main sweeping roller 54 (about its axis of rotation 56) relative to the placement plane 26 is fixed.

[0138] The form-fitting element 92 is guided on the rod 86 in a kinematic manner and in particular in a linearly displaceable manner.

[0139] In one exemplary embodiment, the form-fitting element 92 is designed as a sleeve which is guided on the rod in a linearly guideable manner.

[0140] The form-fitting element 92 is connected to the spring device 96 (see Figure 5 ) is supported on the rod 86. The spring force of the spring device 96 acts so that the form-fitting element 92 is pressed against the housing 78 and thereby against the rail device 88. When the form-fitting element 92 reaches a certain position relative to the matching element 94, a form lock occurs and the handle 84 is prevented from being pivotable (in any direction).

[0141] The operator can cancel the positive lock between the positive lock element 92 and the mating element 94 by pulling the positive lock element 92 away from the rod 86 (away from the axis of rotation 64). To this end, the operator must overcome the spring force of the spring device 96. After canceling the positive lock between the positive lock element 92 and the mating element 94, the operator can swing the handle 84 relative to the chassis 12 and then adjust the height position of the main cleaning roller 54 relative to the support plane 26.

[0142] When the operator no longer applies force, the form-fitting element 92 can be moved again in the direction of the rail arrangement 88 and ensures the form-fitting connection. As described above, in particular, a discrete form-fitting positioning of the handle 84 on the rail arrangement 88 is provided.

[0143] In this respect, reference is made to EP 1 531 202 B1, in which a corresponding elastically prestressed handle is disclosed.

[0144] The handle 84 is in the first end position 98 ( Figure 1 , Figure 3 , Figure 4 ) and a second end position (not shown) in which the swing device 60 can swing relative to the chassis 12 about the rotation axis 64. The first end position 98 is a position of the handle 84 in which the swing device 60 is positioned so that the main sweeping roller 54 has a maximum spacing from the support plane 26 with respect to its rotation axis 56 relative to all other positions.

[0145] The second end position is a position of the handle 84 in which the oscillating device 60 with the main sweeping roller 54 is positioned in such a way that the axis of rotation 56 has a minimum spacing from the support plane 26 .

[0146] In the event of a pivoting movement of the handle 84 out of the first end position 98 , the distance between the axis of rotation 56 and the placement plane 26 is reduced.

[0147] In one embodiment ( Figures 3 to 6 ), the handle 84 is oriented at an acute angle to the placement plane 26 with respect to the rod 86. When pivoting out of the first end position 98, the angle between the handle 84 and the placement plane 26 increases (which causes the axis of rotation 56 to fall).

[0148] In the first end position 98 and in the second end position, the handle 84 can be fixed and in particular locked relative to the chassis 12 , in particular via the rail arrangement 88 by the engagement of the engagement element 94 with the form-fitting element 92 .

[0149] In addition, it may be provided that the first end position 98 and / or the second end position is defined by a stop 100 . When the handle 84 reaches the first end position 98 , the handle 84 and / or an element of the height adjustment device 72 abuts against the stop 100 .

[0150] In one exemplary embodiment, a stop 100 is formed on the rail arrangement 88 and, for example, forms a boundary wall of a slot of the rail arrangement 88 , which (in the exemplary embodiment described) predetermines a minimum pivoting angle and prevents further pivoting toward the placement plane 26 .

[0151] A stop can also be assigned to the second end position in a corresponding manner.

[0152] The first end position 98 is such that, when the handle 84 is in the first end position 98, the main cleaning roller 54 is spaced apart from the resting plane 26. The bristles 102 of the main cleaning roller 54 are spaced apart from the resting plane 26 and do not touch the resting plane.

[0153] In the first end position 98 , the main cleaning roller 54 is raised relative to the resting plane 26 .

[0154] In the first end position 98 of the handle 84 and the raised main sweeping roller 54, the sweeping machine 10 can be guided on the ground surface without the main sweeping roller 54 coming into mechanical contact with the ground surface. The first end position 98 of the handle 84 ensures the travel operation to a certain extent.

[0155] Furthermore, in the first end position 98 of the handle 84, the main sweeping roller 54 can be "lightened". The bristles 102 of the main sweeping roller do not touch the ground on which the sweeping machine 10 is located. As a result, these bristles are not deformed. Thus, when not in operation, these bristles are lightened and their service life can therefore be extended in principle.

[0156] Figures 1 to 3 , this travel state or storage state of the sweeping machine 10 is shown in , in which the handle 84 is in its first end position 98 and the main sweeping roller 54 is thus spaced apart from the support plane 26. There is a spacing between the tips of the bristles 102 and the support plane 26. Figure 3 In the diagram, the corresponding minimum distance is indicated by reference numeral 104 .

[0157] When outside the first end position 98, the main cleaning roller 54 descends and touches the placement plane 26, so that it touches the surface 24 to be cleaned ( Figure 4 , Figure 5 ).

[0158] This means that the bristles 102 are bent due to contact with the floor surface 24 to be cleaned. Figure 4 and Figure 5 This is not shown. The bristles 102 bear against the surface 24 to be cleaned in a partial region in order to be able to exert a mechanical action on the surface to be cleaned.

[0159] The further the handle 84 is pivoted out of the first end position 98 (with corresponding locking via the form-fitting element 92 and the mating element 94 ), the lower the axis of rotation 56 is in the height direction 46 relative to the support plane 26 .

[0160] By correspondingly adjusting the respective swivel position, the properties of the surface 24 to be cleaned can be adapted and, for example, the pressing force acting on the surface 24 to be cleaned can also be adjusted. In addition, bristle wear can also be compensated in the following manner, that is, by selecting a suitable swivel position.

[0161] The chassis 12 comprises a base carrier 106. The front wheel arrangement 22 is arranged directly on the base carrier 106. The base carrier 106 has a plate-shaped configuration at least in the second region 76 of the chassis 12.

[0162] A cleaning material container 108 is detachably held on the base carrier 106 at the second region 76 of the chassis 12. The cleaning material container 108 is used to receive cleaning material that is conveyed into an interior space 110 of the cleaning material container 108 by means of the main cleaning rollers 54.

[0163] The cleaning material container 108 is configured as a box. The box includes a wall 112 surrounding an interior space 110. The wall 112 is open at an end side 114, which faces the housing 78 when the cleaning material container 108 is placed on the chassis 12. During the cleaning operation of the sweeping machine 10, the cleaning material can be transported into the interior space 110 via the corresponding openings 116 of the cleaning material container 108. When the cleaning material container 108 is removed from the sweeping machine 10, the cleaning material container 108 can be emptied via the opening 116.

[0164] The wall 112 of the cleaning material container 108 includes a bottom wall 118. When the cleaning material container 108 is placed on the chassis 12, the bottom wall 118 faces the base carrier 106 and is particularly supported on the base carrier.

[0165] Opposite the bottom wall 118 , the cleaning material container 108 has a top wall 120 .

[0166] The top wall 120 and the bottom wall 118 are connected by a side wall 122. The side wall 122 has a front region 124 which is arranged at or towards the front end 14. The opening 116 is located on the cleaning material container 108 opposite the front region 124.

[0167] In one embodiment, the bottom wall 118 and the top wall 120 are substantially straight. The front region 124 includes a shoulder (see Figure 3 ). These shoulders serve to position the cleaning material container 108 on the chassis 12 in a form-fitting manner and also to provide recesses for mounting elements of the front wheel arrangement 22 .

[0168] The wall 82 of housing 78 is basically formed straightly. This wall is inclined at an acute angle to the placement plane 26. In the illustrated embodiment, this acute angle is approximately 70 °. Wall 112 matches this inclination of the wall 82 of housing 78 at opening 116. Thus, when cleaning material container 108 was placed on chassis 12, this cleaning material container was also supported downwardly toward the placement plane 26 at the wall 82.

[0169] A holding device, which is designated as a whole by 126, is arranged on the chassis 12, which holds the cleaning material container 108 on the chassis 12. The holding device 126 comprises a wall 82 and further form-fitting elements, which ensure a corresponding support for the cleaning material container 108. In particular, lateral form-fitting elements 128 (see Figure 1 ) and the front form-fitting element 130 (see Figure 3 ), when the cleaning material container 108 is positioned as intended on the chassis 12, they prevent the cleaning material container 108 from moving out in the transverse direction 34 (by means of lateral form-fitting elements 128) and from moving out along the longitudinal axis 18 toward the front end 14 (by means of front form-fitting elements 130). The wall 82 of the housing 78 ensures that the movement out toward the rear end 16 is prevented.

[0170] Furthermore, the chassis 12 ensures downward support with the second region 68. As described, the wall 82 also brings about support downward toward the placement plane 26. The front form-fitting element 130 can also be designed to provide downward support.

[0171] The cleaning material container 108 is positioned on the chassis 12 in such a way that it can be removed upwards and in particular without tools, in the direction opposite to the placement plane 26. It is also not necessary to loosen any screws or the like to remove the cleaning material container.

[0172] The housing 78 has an opening 132 on the wall 82 , which is associated with the main sweeping roller 54 . Through the opening 132 , the sweeping material can be conveyed by means of the main sweeping roller 54 through the opening 116 into the sweeping material container 108 .

[0173] A ramp 134 is arranged on the first region 74 of the chassis 12 in the region of the opening 132 , which ramp leads from the support plane 26 to the opening 132 .

[0174] In the absence of force loading, the ramp 134 is oriented at an acute angle to the support plane 26 , specifically in such a way that an inclined plane relative to the opening 132 is formed for the cleaned material.

[0175] The cleaned material is thrown into the opening 132 by the main cleaning roller 54. The ramp supports this throwing in. At the same time, the ramp forms a baffle or boundary surface, which basically prevents the cleaned material from being thrown in the direction of the roller 38 by the main cleaning roller 54 below the base carrier 106.

[0176] In one embodiment, the ramp 134 is movable. The ramp can be mounted on the chassis 12 in a movable manner and / or has inherent movability due to a corresponding construction made of an elastic material, such as a rubber material.

[0177] In one embodiment, one or two side brooms 136 are arranged on the chassis 12. In the embodiment shown, a side broom 136 is arranged on both sides.

[0178] The side broom is held via the arm 138 in a manner that is particularly fixed and pivotable relative to the chassis 12 .

[0179] A broom holder 140 is arranged on the arm 138 , on which a round brush 142 with corresponding bristles is arranged.

[0180] In particular, the round brush is inclined at a relatively small acute angle (for example, in the order of 30°) to the support plane 26 .

[0181] The lateral position of the respective side broom 136 can be fixed via the swivellable side arms 138. In particular, the arms 138 can be pivoted towards the chassis 12 in order to provide a space-optimised storage position of the sweeping machine 12.

[0182] A free space 144 is formed between the support surface 26 and the base carrier 106. The side broom 136 has the task of transporting the sweeping material so that it can pass over the free space 144 and then can be thrown into the sweeping material container 108 through the opening 132 by means of the main sweeping roller 54.

[0183] In one exemplary embodiment, a handle 146 is arranged on the chassis 12 in the region of the front end 14 , by means of which the sweeping machine 10 can be lifted.

[0184] The sweeper 10 works as follows:

[0185] In cleaning operation, the sweeping machine 10 is positioned on the surface 24 to be cleaned via the resting plane 26. The push bow 42 is positioned so that an operator standing on the surface 24 to be cleaned can push the sweeping machine 10 on the surface 24 to be cleaned (using muscle power).

[0186] Before the cleaning operation, the main cleaning roller 54 is in a height position in which the main cleaning roller 54 is spaced apart from the placement plane 26 and therefore does not touch the surface 24 to be cleaned. This is achieved by having the handle 84 in the first end position 98 .

[0187] Before the cleaning operation, the operator guides the handle 84 out of the first end position 98 and ensures that (the form-fitting element 92 with the corresponding mating element 94) is locked in the desired position of the main cleaning roller 54. The corresponding positioning of the handle 84 fixed outside the first end position 98 ensures that the main cleaning roller 54 (with its bristles 102) touches the surface 24 to be cleaned. Depending on the position of the handle 84 as a swiveling position with respect to the rotation axis 64, the rotation axis 86 of the main cleaning roller 54 is in different height positions relative to the support plane 26. This allows an adaptation to a specific surface to be cleaned.

[0188] The operator then pushes the sweeping machine 10 over the surface 24 to be cleaned, and the main sweeping roller 54 can rotate about the axis of rotation 56. The traveling movement of the sweeping machine 10 over the surface 24 to be cleaned ensures the rotational drive of the main sweeping roller 54 about the axis of rotation 56. The direction of rotation is such that the sweeping material located in front of the main sweeping roller 54 on the surface to be cleaned is carried by the main sweeping roller and is dropped into the sweeping material container 108 via the ramp 134 through the opening 132.

[0189] The cleaning material beneath the base carrier 106 located in front of the main cleaning roller 54 is picked up by the cleaning machine 10 .

[0190] The length of the main sweeping roller in a direction parallel to the rotation axis 56 of the chassis 12 (transverse direction 34 ) is 50%, preferably at least 70%, in particular at least 80% of the corresponding width of the chassis 12 in this region.

[0191] By one or two side brooms 136, the sweeping material can be initially picked up outside the "travel path" of the chassis 12 and transported into the travel path. As the sweeping machine 10 passes, the main sweeping roller 54 can also pick up these sweeping materials and throw them into the sweeping material container 108.

[0192] By using the handle 84 and the height adjustment device 72 of the first end position 98, in which the main sweeping roller 54 is spaced apart from the support plane 26 (so that no bristles 102 are located on the support plane 26), a "cleaning-free" travel operation of the sweeping machine 10 is obtained. This travel operation is used, for example, to store the sweeping machine or to selectively "switch off" the sweeping function by the main sweeping roller 54. In addition, when the sweeping machine 10 is parked, the main sweeping roller 54 is also protected, because the bristles 102 are then not subjected to mechanical loading. Contact of the bristles 102 with the ground leads to bending of the bristles and thus to mechanical loading.

[0193] During cleaning operation, the positioning of the main cleaning roller 54 can be adjusted via the operating handle 84 away from the first end position 98 via the height adjustment device 72 , so that an optimized cleaning process adapted to the surface 24 to be cleaned can be carried out.

[0194] For example, wear on the bristles can also be compensated by a height-adjustable match.

[0195] In particular, outside the first end position 98, it is possible that the handle 84 has a plurality of discrete positions and thus also a plurality of discrete height positions of the rotation axis 56 or the placement plane 26. In one embodiment, outside the first end position 98, three or four such discrete positions are provided.

[0196] The sweeping machine 10 comprises a placing device 148. The placing device 148 is configured so that objects, in particular buckets, can be placed on the sweeping machine 10 when the sweeping machine 10 is placed on the placing plane 26, and in particular can also be transported together with the sweeping machine 10 during the sweeping machine 10 travel movement.

[0197] In the cleaning machine 10 ( Figures 1 to 5 ), the placing device 148 is arranged or formed on the cleaning material container 108.

[0198] The placement device 148 includes a placement surface 150. The placement surface 150 is formed flat at least with respect to the envelope. This will be explained in detail below.

[0199] The placement surface has a width B of at least 20 cm in the width direction (see Figure 1 ). The width direction is parallel to the transverse direction 34 and perpendicular to the longitudinal axis 18.

[0200] In a specific embodiment, the width B is 30 cm.

[0201] Furthermore, the placement surface 150 has a length L in a longitudinal direction parallel to the longitudinal axis 18 which is at least 20 cm.

[0202] In a specific embodiment, the length L is 30 cm.

[0203] In addition, the placement surface 150 has a width of at least 400 cm 2 , especially 500 cm 2 The surface area is at least approximately the product of the length L and the width B.

[0204] In a specific embodiment, the surface area is 900 cm 2 .

[0205] In particular, the placement surface 150 is designed such that, for example, a 10-liter household bucket or a 20-liter building bucket can be positioned on the placement surface 150 .

[0206] The placement surface 150 of the placement device 148 is arranged on the cleaning machine 10 in such a way that objects, such as a bucket, can be placed on the placement surface 150 from above and the placement surface 150 then supports the objects downwards.

[0207] The placement surface 150 is designed at least with respect to its envelope parallel to the placement plane 26, or is oriented at a small acute angle of up to 10° to the placement plane 26. This prevents objects from sliding off, at least on a flat base surface 24. In addition, an anti-slip device may be provided, which will be described in detail below.

[0208] In the cleaning machine 10, the placement device 148 is formed on the cleaning material container 108 and thus on the top wall 120. The outer side 152 of the top wall 120 forms or includes the placement surface 150.

[0209] Therefore, when the cleaning material container 108 is removed from the cleaning machine 10, the placement surface 150 is also removed from the cleaning machine 10.

[0210] The placement surface 150 is arranged within the edge wall 154. The edge wall includes a first side wall 156, which extends at least approximately parallel to the longitudinal axis 18. It also includes a second side wall 158 spaced apart from the first side wall 156 in parallel. The first side wall 156 and the second side wall 158 are connected by an end wall 160. The end wall 160 is oriented at least approximately parallel to the transverse direction 34.

[0211] The end wall 160 faces the housing 78. The end wall 160 and the first side wall 156 and the second side wall 158 are designed so that when the cleaning material container 108 is arranged on the sweeping machine 10 as intended, a continuous and in particular stepless transition from the cleaning material container 108 to the housing 78 is obtained at the cleaning material container top.

[0212] The edge wall 154 is open toward the front end 14 (when the cleaning material container 108 is placed on the cleaning machine 10), and the edge wall is open away from the end wall 160. This allows water that may or would accumulate on the placement surface 150 to flow away toward the front (towards the front end 14).

[0213] The placement surface 150 is located between the first side wall 156 , the end wall 160 and the second side wall 158 , and the distance between the first side wall 156 and the second side wall 158 substantially defines a width B of the placement surface 150 .

[0214] The distance between the end wall 116 and the opposite front end portion defines a length L.

[0215] The placement surface 150 is arranged recessed compared to the edge wall 154 .

[0216] A handle 162 is arranged on the edge wall 154 and here on the end wall 160. The handle 162 comprises a bracket with a free space 164 for the fingers of the operator to pass through.

[0217] The cleaning material container 108 can be grasped by the handle 162 and removed from the cleaning machine 10 or placed on the cleaning machine 10 .

[0218] The edge wall 154 prevents the articles positioned on the placement surface 150 from falling sideways and backwards.

[0219] An anti-skid device 166 is assigned to the placement surface 150. The anti-skid device 166 is used to at least make the items placed on the placement surface 150 more difficult to slide off.

[0220] In one embodiment, the anti-slip device 166 includes spaced-apart tabs 168 that are oriented parallel to the longitudinal axis 18 or parallel to the side walls 156, 158. The tabs 168 are oriented transversely and in particular perpendicularly to the end wall 160.

[0221] The tab 168 is made of a non-slip material, such as a corresponding rubber material or plastic material, at least in the region where it comes into contact with the objects to be placed.

[0222] In this embodiment, the envelope of the placement surface 150 is formed by the envelope surface on the web 168 .

[0223] The anti-slip device 168 may also have other configurations, such as an anti-slip pad, which is fixedly or removably positioned between the walls 156 , 158 , 160 .

[0224] In one embodiment, at least one fixing element is assigned to the placement surface 150 , and an object (such as a bucket) positioned on the placement surface 150 can be fixed via the fixing element.

[0225] In one embodiment, a fixing recess 170 or a fixing eyelet 170 is arranged on the first side wall 156 and the second side wall 158. Such a fixing recess 170 is an opening that passes through, in particular, between the outer side of the edge wall 154 and the space above the placement surface 150.

[0226] In such a fastening recess 170 , for example, a hook of a quick-release tensioning device can be accommodated or a tensioning strap can be passed through it.

[0227] In one embodiment, exactly one fixing recess 170 is arranged on each of the first side wall 156 and the second side wall 158 , wherein these fixing recesses are aligned with each other; the connecting line between these fixing recesses 170 is parallel to the end wall 160 or parallel to the transverse direction 34 or perpendicular to the longitudinal axis 18 .

[0228] Each side wall 156 or 158 may also be provided with a plurality of fixing recesses 170 .

[0229] For example, a fixing recess can also be arranged in the front region 124 of the cleaning material container 108, or a plurality of fixing recesses can be arranged. For example, a quick-tightening device can then be arranged between such a fixing recess and the handle 162 (and its free space 164), or a tensioning belt can be guided through it. In this embodiment, the tensioning belt can also be guided crosswise (between the fixing recess in the front region 124 and the fixing recess 170 in the side wall 156 or 158).

[0230] Furthermore, it is also possible that one or more receiving openings 172 ( Figure 1 ). For example, a screwdriver or the like can be accommodated in such a receiving opening 172 .

[0231] During the cleaning operation of the sweeping machine 10, one or more objects, such as a bucket, can be carried along through the placement surface 150. Such objects can be additionally fixed by the fixing element 170 to prevent them from falling during the corresponding travel operation.

[0232] Even when the cleaning machine 10 is parked and placed on the ground with the placement surface 26 , wherein in particular the handle 84 is moved to the first end position 98 , objects can be stored on the cleaning machine 10 via the placement surface 150 .

[0233] In the sweeping machine 10, the placement surface 150 is arranged on the cleaning material container 108. When the cleaning material container 108 is fixed to the chassis 12, the placement surface 150 is located in particular above the wheel axis 36 and above the rotation axis 56 of the main sweeping roller 54 in the height direction 46. In addition, the placement surface is preferably located above one or more side brooms 136 in the height direction 56.

[0234] exist Figure 1 In the embodiment shown in FIG. 1 , the pivot axis 44 of the push-type bow 42 is located above the placement surface 150 .

[0235] The sweeper Figures 6 to 8 The further embodiment shown in and designated by 180 comprises a chassis 182 on which are arranged a rear wheel arrangement 184, a front wheel arrangement 186, a side broom 188 and a main sweeping roller 190. The arrangement is substantially the same as described above in connection with the sweeping machine 10.

[0236] Furthermore, a height adjustment device is provided, which is in principle constructed identically to the height adjustment device 72 of the above-described sweeping machine 10. A handle 192 is also provided, which has a first setting in which the main sweeping roller 190 is spaced apart from the resting plane 26. (The reference numerals used here are the same as those used in the sweeping machine 10).

[0237] A cleaning material container 194 is removably mounted on the chassis 182 .

[0238] A housing 196 corresponding to the housing 78 is provided.

[0239] Different from the housing 78 of the sweeper 10 , the housing 196 further accommodates a suction fan device 198 for generating a negative pressure flow (suction flow).

[0240] A switch 200 is arranged on the housing 196 , via which a motor, in particular an electric motor, of the suction fan device 198 can be activated or deactivated.

[0241] The housing 196 has a receptacle 202 for one or more batteries 204 which provide electrical energy for operating the suction fan arrangement 198 .

[0242] The cleaning material container is provided with an opening 208 on its upper side 206 (which is remote from the placement plane 26). When the cleaning material container 194 is placed on the sweeping machine 180, a channel device 210 is connected to the opening, which connects the interior of the cleaning material container 194 to the suction fan device 198 in a fluid-action manner (acting for the suction flow).

[0243] A filter device 212 is arranged on the channel device 210 , which filters out dust particles and prevents them from being able to reach the impeller mechanism of the fan motor or suction fan device 198 .

[0244] In one embodiment, the filter device 212 includes a housing 214 having a filter corresponding to the filter device 212. The housing 214 is a filter box of the filter device 212.

[0245] With respect to the suction flow, the filter device 212 is connected upstream of the suction fan device 198. With respect to the suction flow, the filter device is connected downstream of the opening 208.

[0246] The housing 214 forms a bridge 216 between the channel device 210 and the housing 196 which is fixedly mounted on the chassis 182 .

[0247] In the region of the housing 214 , the cleaning material container 194 is spaced apart from the housing 214 .

[0248] The combination of the passage device 210 and the housing 214 is designed so that the cleaning material container 194 can be removed from the chassis 182 in a simple manner and can be inserted again while correspondingly solving or establishing the connection between the passage device 210 and the opening 208.

[0249] A storage device 218 having a storage surface 220 for one or more objects is formed on the bridge 216 and in particular on the upper side 222 of the housing 214 . The upper side 222 of the housing 214 is remote from the cleaning material container 194 .

[0250] The placement surface 220 itself or its envelope is parallel to the placement plane 26 or forms an acute angle of at most 10° with the placement plane.

[0251] In particular, the placement surface has a length of at least 20 cm and a width of at least 20 cm. In addition, it has a width of at least 400 cm. 2 surface area.

[0252] In a specific embodiment, the length L is 24 cm, the width B is 23 cm, and the surface area is 552 cm 2 .

[0253] The placement surface 220 may be provided with an anti-skid device as described above in conjunction with the anti-skid device 166. For example, a corresponding tab or anti-skid pad may be provided.

[0254] In the exemplary embodiment shown, the housing 214 has an edge wall 224 which extends in the height direction transversely and in particular perpendicularly to the placement plane 26 in the direction of the cleaning material container 194 .

[0255] At least one fixing recess 226 is arranged on the edge wall 224 (see also Figure 7 and Figure 8 ), the fixing recess is open toward the placement plane 26.

[0256] The edge wall 224 is here a wall which extends parallel to the respective longitudinal axis (transversely to the axis of rotation of the main sweeping roller 190 ).

[0257] A hook, such as a hook of a quick-release device, can be positioned on the fixing recess 226. This allows an object, such as a bucket, to be positioned on the placement surface 220.

[0258] In the case of the sweeping machine 180 , the placement surface 220 is in particular the highest point of the sweeping machine 180 relative to the placement plane 26 , apart from the push-type bracket 228 .

[0259] The use of the bridge 216 as a placement surface 220 results in an optimized utilization of the space of the cleaning machine 180 .

[0260] A placement device 218 having a placement surface 220 is arranged between a housing 196 fixedly connected to the chassis 182 and the channel device 210 .

[0261] With respect to the height direction perpendicular to the placement plane 26, the cleaning material container 194 is arranged between the placement plane 26 and the placement surface 220. It can also be provided here that the cleaning material container 194 is positioned between the placement plane 26 and the suction fan device 198 in the housing 196 in this direction.

[0262] The sweeping material container 194 is also positioned between the filter device 212 and the resting surface 26 .

[0263] In principle, it is also possible to design the channel device 210 accordingly and to form the support device 218 on the channel device 210 . For example, the filter device 212 is then arranged on the housing 196 .

[0264] In the sweeper 180, a negative pressure flow is provided during operation by the suction fan device 198, which acts on the inner space of the sweeping material container 194. This negative pressure flow is mainly used to keep the "dust spreading" to the surrounding environment low during the cleaning process using the sweeper 180. The sweeper 180 uses the rotating main sweeping roller 190 to carry out a cleaning operation, which in principle will stir up dust, which can then be sucked away via the suction fan device 198. The suction fan device 198 is mainly used to suck away this stirred dust, and is not necessarily mainly used to directly suck away dust on the surface 24 to be cleaned.

[0265] In principle, it is also possible in the cleaning machine 180 to drive the main cleaning roller 190 by means of a motor via a corresponding motor.

[0266] In other respects, the sweeping machine 180 functions in principle the same as the sweeping machine 10 with respect to the height adjustment of the main sweeping roller 190 and its spacing from the resting plane when the handle 192 is in the first setting. In addition, the sweeping machine 180 functions in principle the same as the sweeping machine 10 with respect to the placement device 218.
