Description

Sweeper with storage area

The invention relates to a sweeper comprising a chassis, a rear wheel device and a front wheel device which are arranged on the chassis and which define a setup plane of the sweeper on a surface to be cleaned, a push bar which is arranged on the chassis, at least one main sweeping roller which is held on the chassis so as to be rotatable about a rotation axis, and a sweeping waste container which is removably mounted on the chassis.

WO 2008/022699 A2 discloses a hand-held sweeper with a housing that covers a rotatable sweeping roller and that can be moved along a floor surface by means of two rotatably mounted running wheels, wherein the sweeping roller can be driven in rotation by at least one running wheel, and with a U-shaped push bar.

CH 489 235 A discloses a manual pusher for waste collectors and floor cleaners with rotating brushes.

DE 12 25 684 A discloses a sweeper with dust extraction and an adjustable sweeping roller.

DE 10 2014 006 391 A1 discloses a sweeping machine with a collecting container for sweepings that can be attached to the rear of a housing.

EP 1 531 202 Bl discloses a sweeping machine with a housing, a waste container and a sweeping roller covered by the housing, which is mounted on a height adjustment device so that it can rotate about a rotation axis. The height adjustment device can be pivoted by means of an adjustment mechanism about a pivot axis aligned parallel to the rotation axis, whereby the adjustment mechanism has a pivot arm which can pivot about the pivot axis. which protrudes from the housing and can be releasably locked in different pivot positions, and wherein the height adjustment device comprises two support arms which can be pivoted about the pivot axis and on which the sweeping roller is rotatably mounted. The support arms are rigidly connected to one another via a cross strut, wherein the pivot arm is fixed to the cross strut and protrudes from the cross strut in the radial direction with respect to the pivot axis.

DE 10 2018 104 749 A1 discloses a sweeper comprising a chassis, at least one broom arranged on the chassis, and a height adjustment device which is associated with the at least one broom and via which a height position of the at least one broom can be adjusted relative to the chassis.

DE 10 2018 104 744 A1 discloses a sweeper comprising a chassis, a rear wheel device arranged on the chassis, and a push bar which is pivotably arranged on the chassis. A foot tread area is provided which is arranged on the chassis in the area of the rear wheel device, wherein starting from a sweeper properly positioned on a base, the sweeper as a whole can be positioned away from the base into a parking position by an operator by stepping on the foot bar when supported by the rear wheel device on the base.

The invention is based on the object of providing a sweeper of the type mentioned above, which has advantageous operating characteristics.

This object is achieved in the sweeper mentioned at the outset in that a storage device with a storage surface for one or more objects is provided, which is supported by the chassis is held, whereby the storage surface is parallel to the installation plane or is inclined at a maximum angle of 10° to the installation plane.

One or more objects, such as a bucket, can be carried on the storage area when the sweeper is cleaning.

Furthermore, one or more objects can be positioned above the installation level on the sweeper when it is stored.

Because the storage surface is parallel to the installation surface or at most inclined at a small acute angle of 10° to the installation surface, objects are largely prevented from slipping off the installation surface.

In principle, it is possible for the storage surface itself to be flat, or advantageously for the storage surface to have a flat envelope. The flat envelope is formed, for example, on an anti-slip device. In the case of larger objects such as buckets, the corresponding object is usually supported on the storage device using elements that form the flat envelope.

It is advantageous if at least one of the following is provided: the storage area has a width in a width direction which is at least 20 cm, wherein the width direction is oriented perpendicular to a forward direction of travel of the sweeper; the storage area has a length in a longitudinal direction of at least 20 cm, wherein the longitudinal direction is oriented parallel to a forward direction of travel of the sweeper; the storage surface has a surface area of at least 400 cm ² and in particular at least 500 cm ² ; the storage surface is arranged and designed such that, with respect to a height direction which is oriented perpendicular to the installation plane, an object can be placed on the storage surface from above and is supported by the storage surface downwards with respect to the height direction; the storage surface is continuous; at least one fastening recess is assigned to the storage surface.

This results in a correspondingly large storage area, on which, for example, a 10 l household bucket or a 20 l construction bucket can be placed. In specific examples, the surface area of the storage area is approximately 550 cm ² and 900 cm ² .

The corresponding storage area allows an object to be carried with the sweeper when it is being used for transport (with or without cleaning) by supporting it downwards. Furthermore, when the sweeper is parked in a storage area, objects can be positioned on the storage area if the parking is done above the installation level.

A continuous storage area results in optimized use of space, especially so that a bucket can be placed there, for example.

If the storage area has at least one fastening recess, then stored objects can be secured using quick-release fasteners or tensioning straps, for example. It is advantageous if at least one of the following is provided: the axis of rotation of the at least one main sweeping roller is transverse and in particular perpendicular to a forward direction of travel of the sweeping machine; the axis of rotation of the at least one main sweeping roller is parallel to a wheel axis of the rear wheel device; the push bar is arranged on the chassis so as to be pivotable about a pivot axis, the pivot axis being oriented parallel to the axis of rotation of the at least one main sweeping roller; a pivot axis of the push bar is transverse and in particular perpendicular to a forward direction of travel of the sweeping machine; the axis of rotation of the at least one main sweeping roller is parallel to the installation plane; a wheel axis of the rear wheel device is oriented parallel to the installation plane.

This results in a structurally simple design with correspondingly simple operation.

It is particularly advantageous if the storage area is equipped with an anti-slip device. This makes it more difficult for objects to slip off the storage area, for example if a sloped floor area needs to be cleaned. In a structurally simple embodiment, the storage device has parallel spaced webs. The parallel spaced webs define an envelope and in particular a flat envelope. The webs are designed in such a way that they have an anti-slip effect.

In particular, at least one of the following is then provided: the webs are oriented transversely and in particular perpendicularly to a wheel axis of the rear wheel device; the webs are oriented transversely and in particular perpendicularly to the axis of rotation of the at least one main sweeping roller; the webs are oriented parallel to a forward direction of travel of the sweeper; the webs are oriented parallel or at most with an inclination of 10° to the installation plane; the webs are at least partially made of an anti-slip material and, for example, a rubber material.

This results in a structurally simple design.

It is also possible that other types of anti-slip devices such as anti-slip mats or the like are provided.

It is advantageous if the storage area is assigned a wall on which at least one fastening element and/or at least one receiving recess is arranged. The "load" can then be secured on the storage area, for example using a quick release or a Tension belt. The fastening element has the form of a fastening recess or fastening eyelet, for example. Small objects such as screwdrivers or the like can be held in the receiving recess.

It is advantageous if the storage area is limited by an edge wall. This provides a wall on which one or more fastening recesses can be arranged. An edge wall, if it extends beyond the storage area, can also prevent an object from falling out of the storage area in the area of the corresponding edge wall. It can be advantageous, for example, if the sweeper is operated on a floor surface that is inclined to the direction of gravity.

It is advantageous if at least one of the following is provided: the edge wall comprises a handle, which is in particular a handle of the waste container; the edge wall is open towards a front of the sweeper; at least one storage opening is arranged on the edge wall; at least one fastening eyelet and/or at least one fastening recess is arranged on the edge wall; the edge wall projects with at least a partial area in a height direction perpendicular to the installation plane from the storage surface upwards away from the installation plane and/or projects in at least a partial area in the height direction towards the installation plane. A structurally simple structure is achieved if the edge wall includes a handle, which is in particular a handle of the waste container. This allows the number of components to be kept low and results in simplified manufacture.

If the edge wall is open towards the front of the sweeper, then liquid that has accumulated on the storage surface can be easily drained away or liquid accumulation is prevented.

At least one storage opening for tools or the like can be easily positioned on the edge wall.

Fastening eyelets or fastening recesses on the edge wall make it easy to secure "loads" on the storage surface.

It can be provided that the edge wall protrudes upwards from the storage area away from the installation plane and/or downwards in a height direction perpendicular to the installation plane at least in a partial area. Depending on the application of the sweeper, this results in an optimized design.

In particular, the storage surface is spaced from the installation plane in a height direction perpendicular to the installation plane, in particular with at least one of the following: the storage surface is located in the height direction above the at least one main sweeping roller; the storage surface is located in the height direction above at least one side brush; the storage area is located in the vertical direction above a pivot axis of the push bar, or is located in the vertical direction below a pivot axis of the push bar; the storage area is located in the vertical direction above the rear wheel device; the storage area is located in the vertical direction and outside the push bar at a highest point of the sweeper.

This results in easy usability.

In one embodiment, the storage area is firmly connected to the chassis. For example, the storage area is arranged on the waste container or is arranged on a removable housing element.

In one embodiment, the storage surface is arranged on the waste container, with at least one of the following: the storage surface is formed on a wall of the waste container; an edge wall of the storage surface is formed in the waste container.

The waste container can then be used to transport one or more objects on the storage area if the waste container is properly attached to the chassis of the sweeper.

This makes it easy, for example, to create an edge wall on the waste container that limits the storage area. It is also advantageous if a handle on the waste container limits the storage area. This results in optimized use of space and simplified manufacture of the sweeper.

In one embodiment, a suction fan device is provided, by means of which an interior of the waste container can be subjected to a vacuum flow, and a filter device is provided for the vacuum flow. In principle, during cleaning operation, at least one main sweeping roller of the sweeper stirs up dust, which can then get into the area around the sweeper. The suction fan device can reduce such "dust exposure" to the area around the sweeper. As a rule, the primary task of the suction fan device is to keep the dust load in the area to a minimum, and it is not the primary task of the suction fan device to directly vacuum the area to be cleaned.

In one embodiment, the storage area is arranged or formed on a housing, the housing being a housing for the suction fan device and/or a housing for the filter device. This allows components of the sweeper to be used in an optimized manner. If a suction fan device is provided, it is generally advantageous if the sweeping waste container is supplied with the vacuum flow via an upper side of the sweeping waste container, the upper side facing away from the installation plane. One or more openings are arranged on this upper side, via which there is a fluid-effective connection with the suction fan device and via which the vacuum flow is coupled in. This means that there are components of the sweeper which are arranged above the sweeping waste container in relation to a height direction perpendicular to the installation plane. Such components include a housing which is a housing for the suction fan device and/or a housing for the filter device. This allows the corresponding housing to be optimized. Can be used to transport one or more objects using the appropriate storage area.

In one embodiment, the storage area is arranged on an openable cover of the housing. For example, the housing is a filter box and the cover on which the storage area is formed is a cover via which, after opening, a filter of the filter device can be inserted or removed from the filter box.

It is advantageous if there is at least one fastening recess on the housing. For example, a hook from a quick release can be inserted into the fastening recess or a strap from a tensioning belt can be passed through. This means that components of the housing can be used to fasten "loads" to the storage area with little effort in terms of manufacturing and construction.

It is advantageous if at least one of the following is provided: the waste container is arranged between the storage area and the installation level; the waste container is arranged between the installation level and the suction fan device; the waste container is arranged between the installation level and the filter device.

This results in optimized use of space.

Furthermore, it is particularly advantageous if at least one of the following is provided: the storage area is arranged on a bridge which is positioned above the waste container in terms of height; the filter device is arranged on a bridge which is positioned above the waste container in terms of height.

As mentioned above, it is useful if one or more openings, through which a vacuum flow is coupled into the waste container, are located on the top of the waste container facing away from the installation level. It is then in turn advantageous if a bridge is provided, through which the vacuum flow is then fed to the waste container. The bridge is then arranged above the waste container in a vertical direction perpendicular to the installation level, and this results in a useful arrangement for a storage area for taking one or more objects with the sweeper.

In one embodiment, the filter device is arranged on a bridge which is positioned accordingly in relation to the height direction above the waste container.

In particular, the sweeper is designed as a hand-held sweeper, which can be guided by an operator over the floor to be cleaned using the push bar.

In an advantageous embodiment, a height adjustment device is provided, via which a height position of the rotation axis of the at least one main sweeping roller can be adjusted to the installation plane, and a handle is provided which can be pivoted to the chassis, which is mechanically coupled to the height adjustment device, and via which a height position of the rotation axis to the installation plane can be set by an operator. The handle has an end position in which the at least one main sweeping roller is spaced apart from the installation plane. The spacing in the mentioned end position protects the bristles of at least one main sweeping roller. They are then not subjected to any mechanical stress due to contact with a surface in the corresponding end position. This in turn means that the sweeper can be parked on the floor with the installation level on without mechanical stress being placed on the at least one main sweeping roller. This results in an extended service life. This also means that the storage area in a corresponding parking position of the sweeper, in which the sweeper is placed on the floor above the installation level, can be used as a storage space for one or more objects.

In particular, according to the invention, the waste container is used with a storage area for storing objects.

Figure 8 is an enlarged view of Report A according to Figure 7.

A first embodiment of a sweeper according to the invention, which is shown in Figures 1 to 5 and designated by 10, comprises a chassis 12. The chassis 12 forms the body or the base of the sweeper 10 and holds (directly or indirectly) the components of the sweeper 10. The chassis 12 ensures the mechanical stability of the sweeper 10 and holds its components.

The chassis 12 has a front end 14 and a rear end 16. A longitudinal axis 18 of the chassis 12 (and thus also of the sweeper 10) runs between the front end 14 and the rear end 16.

The sweeper 10 is mounted on a surface 24 to be cleaned (see Figure 3) via a rear wheel device 20 and a front wheel device 22. The rear wheel device 20 and the front wheel device 22 define a mounting plane 26 of the sweeper 10 on the surface 24 to be cleaned. If the surface 24 to be cleaned is flat, then the mounting plane 26 coincides with the surface to be cleaned.

The rear wheel device 20 is arranged on the chassis 12 in the area of the rear end 16. The rear wheel device 20 has a right rear wheel 30 and a left rear wheel 32 in relation to a forward direction of travel 28 of the sweeper 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 installation plane 26. The right rear wheel 30 and the left rear wheel 32 are positioned on the chassis 12 so that they can rotate about a common wheel axis 36. The wheel axis 36 is parallel to the transverse direction 34. It is perpendicular to the longitudinal axis 18. It is perpendicular to the forward direction 28. The wheel axis 36 is parallel to the installation plane 26.

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

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

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

The roller 38 is rotatable about a roller axis. In the forward travel direction 28 of the sweeper 10, this roller axis is parallel to the wheel axis 36. The wheel axis 36 is a fixed axis in relation to the chassis 12. The position of the roller axis in relation to the chassis 12 depends on the position of the roller 38 if it is designed as a steering roller.

The roller axis of the roller 38 is parallel to the installation plane 26. The sweeper 10 comprises a push bar 42, which is arranged on the chassis in the area of the rear end 16 and in particular in the area of the rear wheel device 20. An operator standing on the floor 24 to be cleaned can use the push bar 42 to guide and in particular push the sweeper 10 over the floor to be cleaned.

In one embodiment, no motor drive is provided for the sweeper 10 and the travel movement is operator-driven (via operator force).

In one embodiment, the push bar 42 can be pivoted about a pivot axis 44 to the chassis 12. A defined pivot position of the push bar 42 to the chassis 12 can be set continuously or in stages. This means that the push bar 42 can be pivoted for storing the sweeper 10 in such a way that the height of the sweeper 10 is minimized in a height direction 46 perpendicular to the installation plane 26 and, for example, does not protrude beyond the top of the sweeper 10.

Due to the pivotability of the push bar 42 about the pivot axis 44, the size of the sweeper 10 can be adjusted to suit an operator during sweeping operation.

The pivot axis 44 is parallel to the installation plane 26. It is perpendicular to the center plane 40. It is perpendicular to the longitudinal axis 18 of the chassis 12.

In one embodiment, a corresponding pivot bearing for the pivotable connection of the push bar 42 to the chassis 12 is arranged such that the pivot axis 44 lies in the height direction 46 above the wheel axis 36 of the rear wheel device 20. In one embodiment, the push bar comprises a first rod portion 48 which is pivotally connected to the chassis 12 in the region of the left rear wheel 32 and a spaced second rod portion 50 which is pivotally connected to the chassis 12 in the region of the right rear wheel 30.

The first rod portion 48 and the second rod portion 50 are connected to the chassis 12 via a distal end portion. A third rod portion 52 is provided which connects the first rod portion 48 and the second rod portion 50 to one another in a proximal end portion. The third rod portion 52 is a primary holding portion for an operator who guides the sweeper 10 over the surface 24 to be cleaned.

A main sweeping roller 54 is arranged on the chassis 12 and is rotatable about a rotation axis 56. The main sweeping roller 54 comprises a cylindrical carrier 58 on which a plurality of bristles are arranged.

The rotation axis 56 is parallel to the installation plane 26. It is parallel to the wheel axis 36 or parallel to the pivot axis 44. It is perpendicular to the center plane 40. It is parallel to the transverse direction 34. The rotation axis 56 is perpendicular to the longitudinal axis 18. It is perpendicular to the forward direction 28.

When the sweeper 10 is in sweeping operation, the bristles of the main sweeping roller 54 act on the surface 24 to be cleaned (see Figure 5; Figure 5 shows a position of the main sweeping roller 54 in which its bristles touch the surface 24 to be cleaned and thereby act on it mechanically. This leads to a corresponding deformation of the bristles, which is not shown in Figure 5 for illustrative reasons.) The main sweeping roller 54 is arranged between the left rear wheel 32 and the right rear wheel 30 in the region of the rear end 16 of the chassis 12.

A swing device 60 is positioned on the chassis 12 via a pivot bearing 62. The pivot bearing 62 defines a rotation axis 64.

The axis of rotation 64 is parallel to the installation plane 26. It is parallel to the rotation axis 56. It is perpendicular to the center plane 40. It is parallel to the wheel axis 36. It is parallel to the transverse direction 34. It is perpendicular to the longitudinal axis 18.

The swing arm device 60 has a first region 66, a second region 68, and a third region 70. The second region 68 lies between the first region 66 and the third region 70. The swing arm device 60 is held on the chassis 12 by means of the pivot bearing 62 via the second region 68.

In the first region, the main sweeping roller 54 is held on the swing device 60 so as to be rotatable about the rotation axis 56 via a corresponding roller pivot bearing.

Depending on the rotational position of the swing device 60 about the rotation axis 64, the rotation axis 56 of the main sweeping roller 54 is at different height positions (in the height direction 46) to the installation plane 26. This is explained in more detail below.

A height adjustment device 72 is formed via the swing device 60, with which the height position of the main sweeping roller 54 of the installation level 26 can be adjusted depending on the rotational position of the swing device 60 about the rotation axis 64. It can be provided that the swing device 60 is assigned a guide device in order to guide it with respect to the chassis 12 and thus the main sweeping roller 54.

In one embodiment, the swing mechanism comprises spaced apart swing elements which are connected to one another and are connected to one another, for example, at the third region 70. Between the spaced apart swing elements, the main sweeping roller 54 is positioned at the first region 66 on the corresponding pivot bearing for rotation about the rotation axis 56.

The chassis 12 comprises a first region 74, at which the rear end 16 is located, and a second region 76, which follows the first region 74 in the longitudinal axis 18 and at which the front end 14 is located.

A housing 78 is arranged on the first region 74 and has a housing interior 80 (see Figure 3). The height adjustment device 72 is arranged in the housing interior 80.

The housing 78 has a wall 82 as a boundary to the second region 76.

In particular, a pivot bearing for the main sweeping roller 54 is also arranged in the housing interior 80 for its rotatable mounting about the rotation axis 56. Furthermore, the swing device 60 with the pivot bearing 62 is arranged in the housing interior 80.

A handle 84 is provided for an operator to adjust the height of the main sweeping roller 54 in relation to the installation plane 26. The handle 84 comprises a rod 86. This rod 86 is rigidly connected to the third region 70 of the swing device 60; the handle 84 is mechanically coupled to the swing device 60 via the rod 86. The handle 84 can thus be rotated or pivoted relative to the chassis 12 via the rotation axis 64.

A track device 88 is located on the housing 78. The track device 88 serves to determine a specific rotational position or swivel position of the handle 84 in relation to the chassis 12. It also indicates to an operator which rotational position the handle 84 is in in relation to the chassis 12. The specific rotational position in turn corresponds to a height position of the main sweeping roller 54 (relative to the rotation axis 56) above the installation level 26.

The track device 88 comprises a circular track 90 with opposing circular track elements, between which there is a slot. The rod 86 is inserted through the slot.

A form-locking element 92 is located on the rod 86 outside the housing interior 80. This form-locking element 92 serves to determine a pivoting position (rotational position) of the handle 84 on the circular path 90 and thereby also to determine a specific rotational position of the swing device 60 in relation to the chassis 12.

Counter elements 94 and in particular spaced-apart discrete elements 94 are arranged on the circular path 90. These correspond to the form-locking element 92 in such a way that in certain discrete positions the form-locking element 92 can be latched onto the counter element 94, thereby preventing the handle 84 from pivoting relative to the chassis 12. This in turn prevents the swinging device 60 from rotating about the axis of rotation 64. This in turn means that a certain height position of the main sweeping roller 54 (relative to its axis of rotation 56) relative to the installation plane 26 is fixed. The form-locking element 92 is guided on the rod 86 in a movable and, in particular, linearly displaceable manner.

In one embodiment, the form-locking element 92 is designed as a sleeve which is guided linearly displaceably on the rod.

The form-locking element 92 is supported on the rod 86 via a spring device 96 (see Figure 5). A spring force of the spring device 96 acts in such a way that it presses the form-locking element 92 against the housing 78 and thereby against the track device 88. When a certain position of the form-locking element 92 in relation to the counter elements 94 is reached, a form-locking occurs and the pivotability of the handle 84 (in any direction) is blocked.

An operator can remove the positive locking between the positive locking element 92 and the counter elements 94 by pulling the positive locking element 92 away from the rod 86 (away from the rotation axis 64). To do this, he must overcome the spring force of the spring device 96. After removing the positive locking between the positive locking element 92 and the counter elements 94, he can then pivot the handle 84 relative to the chassis 12 and then adjust the height position of the main sweeping roller 54 to the installation plane 26.

If he then no longer exerts any force, the positive locking element 92 can move again in the direction of the track device 88 and a positive locking can be ensured. As mentioned above, in particular discrete positive locking positions of the handle 84 on the track device 88 are provided.

In this context, reference is made to EP 1 531 202 Bl, in which a corresponding elastically prestressed handle is disclosed. The handle 84 is pivotable about the rotation axis 64 relative to the chassis 12 between a first end position 98 (Figures 1, 3, 4) and a second end position (not shown in the figures). The first end position 98 is a position of the handle 84 in which the swing device 60 is positioned such that the main sweeping roller 54 has the greatest distance from the installation plane 26 with respect to its rotation axis 56 in relation to all other positions.

The second end position is a position of the handle 84 in which the swing device 60 with the main sweeping roller 54 is positioned such that the rotation axis 56 has the smallest distance to the installation plane 26.

When the handle 84 pivots out of the first end position 98, the distance between the rotation axis 56 and the installation plane 26 decreases.

In one embodiment (Figures 3 to 6), the handle 84 is oriented at an acute angle to the installation plane 26 relative to the rod 86. When pivoting out of the first end position 98, the angle between the handle 84 and the installation plane 26 increases (which leads to a lowering of the rotation axis 56).

In the first end position 98 and the second end position, the handle 84 can be fixed and in particular locked relative to the chassis 12, in particular via the track device 88 by engagement of the counter elements 94 on the form-fitting element 92.

It can additionally 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 rests against the stop 100. In one embodiment, the stop 100 is formed on the track device 88 and forms, for example, a boundary wall of the slot of the track device 88, which (in the described embodiment) specifies the minimum pivot angle and blocks further pivoting toward the installation plane 26.

In a similar way, a stop can also be assigned to the second end position.

The first end position 98 is such that in this first end position 98 of the handle 84 the main sweeping roller 54 is spaced from the installation plane 26. Bristles 102 of the main sweeping roller 54 are spaced from the installation plane 26 and do not touch it.

In the first end position 98, the main sweeping roller 54 is raised relative to the installation level 26.

In the first end position 98 of the handle 84 with the main sweeping roller 54 raised, the sweeping machine 10 can be guided over a floor surface without the main sweeping roller 54 coming into mechanical contact with the floor surface. The first end position 98 of the handle 84 provides a sort of ferry operation.

Furthermore, in the first end position 98 of the handle 84, the main sweeping roller 54 can be "relieved". Its bristles 102 do not touch the ground on which the sweeping machine 10 is placed. As a result, they do not experience any deformation. They are thus relieved of load when not in use and their service life can thus be extended.

In Figures 1 to 3, such a driving state or storage state of the sweeper 10 is shown, in which the handle 84 is in its first end position 98 and thereby the main sweeping roller 54 is spaced from the installation plane 26 There is a distance between the tips of the bristles 102 and the installation plane 26. In Figure 3, a corresponding minimum distance is indicated by the reference number 104.

Outside the first end position 98, the main sweeping roller 54 is lowered and touches the installation plane 26 such that a surface 24 to be cleaned is touched (Figures 4, 5).

This means that bristles 102 are bent due to contact with the floor 24 to be cleaned. This is not shown in Figures 4 and 5 for illustrative reasons. The bristles 102 lie in a partial area against the surface 24 to be cleaned in order to be able to act on it mechanically.

The further the handle 84 is pivoted out of the first end position 98 (with corresponding locking via the form-locking element 92 and the counter elements 94), the lower the rotation axis 56 is in the height direction 46 to the installation plane 26.

By adjusting the respective pivot position accordingly, an adjustment to the nature of the surface 24 to be cleaned can be made and, for example, a contact pressure on the surface 24 to be cleaned can also be set. Furthermore, bristle wear can be compensated by selecting the appropriate pivot position.

The chassis 12 comprises a base support 106. The front wheel device 22 is seated directly on the base support 106. The base support 106 has a plate-shaped design at least in the second region 76 of the chassis 12.

A sweepings container 108 is detachably held on the base support 106 on the second region 76 of the chassis 12. The sweepings container 108 serves to receive sweepings, which are conveyed by the main sweeping roller 54 into an interior space 110 of the sweepings container 108. The sweepings container 108 is designed as a box. It comprises a wall 112 which surrounds the interior 110. The wall 112 is open on a front side 114 which faces the housing 78 when the sweepings container 108 is seated on the chassis 12. Sweepings can be conveyed into the interior 110 via a corresponding opening 116 of the sweepings container 108 during sweeping operation of the sweeping machine 10. When the sweepings container 108 is removed from the sweeping machine 10, the sweepings container 108 can be emptied via the opening 116.

The wall 112 of the waste container 108 comprises a bottom wall 118. When the waste container 108 is seated on the chassis 12, the bottom wall 118 faces the base support 106 and is supported in particular on the latter.

Opposite the bottom wall 118, the waste container 108 has a ceiling wall 120.

The top wall 120 and the bottom wall 118 are connected by a side wall 122. This side wall has a front area 124 which is arranged at the front end 14 or faces it. The opening 116 on the waste container 108 is positioned opposite this front area 124.

In one embodiment, the bottom wall 118 and the top wall 120 are essentially straight. The front area 124 includes shoulders (see Figure 3). These serve to position the waste container 108 in a form-fitting manner on the chassis 12 and also to provide recesses for mounting elements of the front wheel device 22.

The wall 82 of the housing 78 is essentially straight. It is inclined at an acute angle to the installation plane 26. In the illustrated In the embodiment, this acute angle is approximately 70°. The wall 112 is adapted to the inclination of the wall 82 of the housing 78 at the opening 116. As a result, the waste container 108, when it is seated on the chassis 12, can also be supported on the wall 82 downwards towards the installation plane 26.

A holding device, designated as a whole by 126, is arranged on the chassis 12 and holds the waste container 108 on the chassis 12. This holding device 126 comprises the wall 82 and further form-locking elements, which ensure appropriate support of the waste container 108. In particular, lateral form-locking elements 128 (see Figure 1) and front form-locking elements 130 (see Figure 3) are provided, which prevent the waste container 108 from moving out when it is properly positioned on the chassis 12 in the transverse direction 34 (lateral form-locking elements 128) and in the longitudinal axis 18 towards the front end 14 (front form-locking element 130). The wall 82 of the housing 78 ensures that the outward movement towards the rear end 16 is blocked.

Furthermore, the chassis 12 with the second region 68 provides support downwards. As mentioned, the wall 82 also provides support downwards towards the installation plane 26. The front form-fitting element 130 can also be designed in such a way that support downwards is provided.

The waste container 108 is positioned on the chassis 12 in such a way that it can be removed upwards in a direction opposite to the direction of the installation plane 26 and, in particular, can be removed without tools. No screws or the like need to be loosened in order to remove the waste container.

The housing 78 has an opening 132 on the wall 82, which is assigned to the main sweeping roller 54. Through the opening 132, Sweepings are transported by means of the main sweeping roller 54 through the opening 116 into the sweepings container 108.

On the first area 74 of the chassis 12, in the area of the opening 132, there is a ramp 134 which leads from the installation level 26 to the opening 132.

Without force loading, the ramp 134 is oriented at an acute angle to the installation plane 26, in such a way that an inclined plane to the opening 132 is formed for sweepings.

Sweepings are thrown into the opening 132 by the main sweeping roller 54. The ramp supports this throwing. At the same time, it forms an apron or boundary surface, which essentially prevents sweepings from being thrown by the main sweeping roller 54 below the base support 106 in the direction of the roller 38.

In one embodiment, the ramp 134 is movable. It can be movably mounted on the chassis 12 and/or have its own mobility through a corresponding design made of an elastic material such as a rubber material.

In one embodiment, one or two side brushes 136 are arranged on the chassis 12. In the embodiment shown, one side brush 136 is arranged on each side.

A side brush is held by an arm 138, in particular lockably pivotable to the chassis 12.

A broom holder 140 is attached to the arm 138. A round brush 142 with corresponding bristles is attached to the broom holder 140. In particular, the round brush is inclined at a small acute angle (for example in the order of 30°) to the installation plane 26.

A lateral position of the corresponding side broom 136 can be determined via the pivotable side arm 138. The arm 138 can be pivoted in particular towards the chassis 12 in order to provide a space-optimized storage position for the sweeper 12.

A free space 144 is formed between the installation level 26 and the base support 106. It is the task of the side brushes 136 to transport sweepings in such a way that they can be driven over the free space 144 and then can be thrown through the opening 132 into the sweepings container 108 by means of the main sweeping roller 54.

In one embodiment, a handle 146 is arranged on the chassis 12 in the region of the front end 14, by means of which the sweeper 10 can be carried.

The sweeper 10 works as follows:

During cleaning operation, the sweeper 10 is set up on the surface 24 to be cleaned via the installation level 26. The push bar 42 is positioned such that an operator standing on the surface 24 to be cleaned can push the sweeper 10 over the surface 24 to be cleaned (using muscle power).

Before a cleaning operation, the main sweeping roller 54 is in a height position at which it is spaced apart from the installation plane 26 and thus does not touch the surface 24 to be cleaned. This is achieved by the first end position 98 of the handle 84. Before cleaning, an operator moves the handle 84 out of the first end position 98 and ensures that the form-fitting element 92 engages with the corresponding counter-elements 94 in the desired position of the main sweeping roller 54. The corresponding position of the fixed handle 84 outside the first end position 98 ensures that the main sweeping roller 54 (with its bristles 102) touches the surface 24 to be cleaned. Depending on the position of the handle 84 as a pivoting position relative to the rotation axis 64, the rotation axis 86 of the main sweeping roller 54 is at different heights relative to the installation plane 26. This allows adaptation to the specific surface to be cleaned.

An operator then pushes the sweeper 10 over the area 24 to be cleaned. The main sweeper roller 54 can be rotated about the rotation axis 56. A driving movement of the sweeper 10 on the floor 24 to be cleaned causes the main sweeper roller 54 to rotate about the rotation axis 56. The direction of rotation is such that sweepings that are on the area to be cleaned in front of the main sweeper roller 54 are carried along by the latter and thrown over the ramp 134 through the opening 132 into the sweepings container 108.

The sweeping machine 10 picks up sweeping material which is located below the base support 106 in front of the main sweeping roller 54.

A length of the main sweeping roller in a direction parallel to the axis of rotation 56 (in the transverse direction 34) of the chassis 12 is 50% and preferably at least 70% and in particular at least 80% of the corresponding width of the chassis 12 in this area.

By means of one or two side brushes 136, sweepings can initially be picked up outside the "channel" of the chassis 12 and conveyed into this channel. When the sweeper 10 drives over it, the The main sweeping roller 54 also picks up this debris and throws it into the debris container 108.

The height adjustment device 72 with the handle 84 and the first end position 98, in which the main sweeping roller 54 is spaced apart from the installation level 26 (so that none of the bristles 102 are on the installation level 26), results in a "clean-free" sweeping operation of the sweeping machine 10. Such a sweeping operation is used, for example, to stow the sweeping machine or to specifically "switch off" the sweeping function by the main sweeping roller 54. Furthermore, when the sweeping machine 10 is switched off, the main sweeping roller 54 is protected because the bristles 102 are then not subjected to mechanical stress. Contact between bristles 102 and a floor leads to bristles bending and thus to mechanical stress.

For a cleaning operation, the position of the main sweeping roller 54 can be adjusted by operating the handle 84 from the first end position 98 via the height adjustment device 72 in order to be able to carry out an optimized cleaning process adapted to the surface 24 to be cleaned.

For example, bristle wear can also be compensated by adjusting the height setting.

In particular, outside the first end position 98, a plurality of discrete positions of the handle 84 and thus also a plurality of discrete height positions of the rotation axis 56 or the installation plane 26 are possible. In one embodiment, three or four such discrete positions are provided outside the first end position 98.

The sweeper 10 comprises a storage device 148. This storage device 148 is designed such that, when the sweeper 10 is set up with the installation level 26, objects and in particular a bucket on the sweeper 10 and, in particular, can be transported with the sweeper 10 during a driving movement.

In the sweeper 10 (Figures 1 to 5), the storage device 148 is arranged or formed on the sweepings container 108.

The storage device 148 comprises a storage surface 150. The storage surface 150 is flat at least with respect to an envelope. This is explained in more detail below.

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

In a specific example, the width B is 30 cm.

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

In a specific example, the length L is 30 cm.

Furthermore, the storage area 150 has a surface area of at least 400 cm ² and in particular 500 cm ² . This surface area is at least approximately the product of the length L and the width B.

In a specific example, the surface area is 900 cm ² .

In particular, the storage surface 150 is designed such that, for example, a 10 l household bucket or a 20 l construction bucket can be positioned on the storage surface 150. The storage surface 150 of the storage device 148 is arranged on the sweeper 10 in such a way that an object (such as a bucket) can be placed on the storage surface 150 from above and then the storage surface 150 supports the object downwards.

The storage surface 150 is designed to be parallel to the installation plane 26, at least with respect to its envelope, or is oriented at a small acute angle of at most 10° to the installation plane 26. This prevents the object from slipping, at least when the surface 24 is flat. An anti-slip device can also be provided, which is described in more detail below.

In the sweeper 10, the storage device 148 is formed on the waste container 108 and thereby on the ceiling wall 120. An outer side 152 of the ceiling wall 120 forms or comprises the storage surface 150.

Accordingly, even when the sweeping waste container 108 is removed from the sweeping machine 10, the storage surface 150 is removed from the sweeping machine 10.

The storage surface 150 is arranged within an edge wall 154. The edge wall comprises a first lateral wall 156 which extends at least approximately parallel to the longitudinal axis 18. It further comprises a second lateral edge wall 158 which is spaced parallel to the first lateral wall 156. The first lateral wall 156 and the second lateral wall 158 are connected by an end wall 160. The end wall 160 is aligned at least approximately parallel to the transverse direction 34.

The front wall 160 faces the housing 78. The front wall 160 and the first lateral wall 156 and the second lateral wall 158 are designed such that a continuous and in particular step-free transition from the waste container 108 to the housing 78 at its top is achieved when the waste container 108 is properly seated on the sweeping machine 10. The edge wall 154 is open towards the front end 14 (when the waste container 108 is attached to the sweeper 10); it is open facing away from the front wall 160. This allows water, in particular, which may collect on the storage surface 150 or would otherwise collect, to flow forward (towards the front end 14).

The storage surface 150 lies between the first lateral wall 156, the front wall 160 and the second lateral wall 158. A distance between the first lateral wall 156 and the second lateral wall 158 essentially defines the width B of the storage surface 150.

A distance between the end wall 116 and the opposite front end defines the length L.

Opposite the edge wall 154, the storage surface 150 is recessed.

A handle 162 is arranged on the edge wall 154 and thereby on the front wall 160. The handle 162 comprises a bracket with a free space 164 for the operator's fingers to pass through.

The dirt container 108 can be grasped via the handle 162 and removed from the sweeper 10 or inserted into the sweeper 10.

The edge wall 154 prevents objects positioned on the storage surface 150 from falling sideways and to the rear.

The storage surface 150 is assigned an anti-slip device 166. The anti-slip device 166 serves to at least make it more difficult for objects placed on the storage surface 150 to slip. In one embodiment, the anti-slip device 166 comprises spaced webs 168 which are aligned parallel to the longitudinal axis 18 or parallel to the lateral walls 156, 158. The webs 168 are aligned transversely and in particular perpendicularly to the end wall 160.

The webs 168 are made of a slip-resistant material such as a corresponding rubber material or plastic material, at least in an area that comes into contact with an object to be deposited.

In such an embodiment, an envelope of the storage surface 150 is formed by an envelope surface on the webs 168.

The anti-slip device 168 can also have other designs, such as a slip-resistant mat which is fixedly or removably positioned between the walls 156, 158, 160.

In one embodiment, the storage surface 150 is assigned at least one fastening element, via which a fixation of objects which are positioned on the storage surface 150 (such as a bucket) can be achieved.

In one embodiment, it is provided that a fastening recess 170 or fastening eyelet 170 is arranged on the first lateral wall 156 and the second lateral wall 158. Such a fastening recess 170 is an opening which is in particular continuous between an outer side of the edge wall 154 and a space above the storage surface 150.

In such a fastening recess 170, for example, a hook of a quick release can be accommodated or a tensioning belt can be pulled through. In one embodiment, exactly one fastening recess 170 is arranged on the first lateral wall 156 and the second lateral wall 158, wherein these fastening recesses are aligned with one another; a connecting line between these fastening recesses 170 lies parallel to the end wall 160 or parallel to the transverse direction 34 or perpendicular to the longitudinal axis 18.

Several fastening recesses 170 can also be provided per lateral wall 156 or 158.

For example, a fastening recess can also be arranged in the front area 124 of the waste container 108 or several fastening recesses can be arranged. For example, a quick release can then be arranged between such a fastening recess and the handle 162 (with its free space 164) or a tensioning belt can be passed through. In such an embodiment, a cross-over guide of a tensioning belt (between a fastening recess on the front area 124 and a fastening recess 170 on a lateral wall 156 or 158) is also possible.

Furthermore, it is also possible for one or more storage openings 172 (Figure 1) to be arranged or formed on the edge wall 154. A screwdriver or the like can be accommodated in such a storage opening 172, for example.

The storage area 150 can be used to carry one or more objects, such as a bucket, during a cleaning operation of the sweeper 10. Such an object can be additionally secured using fastening elements 170 in order to prevent it from falling down during a corresponding sweeping operation. Even when the sweeper 10 is parked and the installation level 26 is resting on a floor (in which case the handle 84 in particular is brought into the first end position 98), objects can be stored on the sweeper 10 via the storage surface 150.

The storage area 150 is arranged on the sweeping waste container 108 in the sweeping machine 10. If the sweeping waste container 108 is fixed to the chassis 12, then the storage area 150 is located in particular above the wheel axis 36 and above the rotation axis 56 of the main sweeping roller 54 with respect to the height direction 46. Furthermore, the storage area is then preferably located above the side brush(es) 136 with respect to the height direction 56.

In the embodiment shown in Figure 1, the pivot axis 44 of the push bar 42 is located above the storage surface 150.

A further embodiment of a sweeper, which is shown in Figures 6 to 8 and designated 180, comprises a chassis 182 on which a rear wheel device 184, a front wheel device 186, side brushes 188 and a main sweeping roller 190 are arranged. The arrangement is basically the same as described above with reference to the sweeper 10.

Furthermore, a height adjustment device is provided, which is basically designed in the same way as the height adjustment device 72 of the sweeping machine 10 described above. A handle 192 is provided, which has a first setting in which the main sweeping roller 190 is spaced from a mounting plane 26. (The same reference numeral is used here as for the sweeping machine 10.)

A removable waste container 194 is mounted on the chassis 182.

A housing 196 is provided which corresponds to the housing 78. In contrast to the housing 78 of the sweeper 10, the housing 196 also accommodates a suction fan device 198 for generating a negative pressure flow (suction flow).

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

The housing 196 has a receptacle 202 for one or more batteries 204, which provide the electrical energy for operating the suction fan device 198.

The dirt container is provided with an opening 208 on its upper side 206 (which faces away from the installation plane 26). When the dirt container 194 is seated on the sweeping machine 180, a channel device 210 is connected to the opening 208, which connects an interior of the dirt container 194 with the suction fan device 198 in a fluid-effective manner (effective for a suction flow).

A filter device 212 is arranged on the duct device 210, which filters out dust particles and prevents them from reaching the blower motor or an impeller device of the suction blower device 198.

In one embodiment, the filter device 212 comprises a housing 214, which has a corresponding filter of the filter device 212. The housing 214 is a filter box of the filter device 212.

In relation to the suction flow, the filter device 212 is connected upstream of the suction fan device 198. In relation to the suction flow, it is connected downstream of the opening 208. The housing 214 forms a bridge 216 between the channel device 210 and the housing 196, which is fixedly mounted on the chassis 182.

In the area of the housing 214, the waste container 194 is spaced apart from this housing 214.

The combination of channel device 210 and housing 214 is designed such that the waste container 194 can be easily removed from the chassis 182 and reinserted with a corresponding solution of the connection of the channel device 210 to the opening 208 or the production of this connection.

A storage device 218 with a storage surface 220 for one or more objects is formed on the bridge 216 and in particular on an upper side 222 of the housing 214. This upper side 222 of the housing 214 faces away from the waste container 194.

The storage surface 220 itself or an envelope lies parallel to the installation plane 26 or at an acute angle of at most 10° to it.

In particular, it has a length L of at least 20 cm and a width of at least 20 cm. Furthermore, it has a surface area of at least 400 ^cm2 .

In a concrete example, the length L is 24 cm, the width B is 23 cm and the surface area is 552 cm ² .

The storage surface 220 can be provided with an anti-slip device as described above with reference to the anti-slip device 166. For example, corresponding webs or an anti-slip mat are provided. In the embodiment shown, the housing 214 has an edge wall 224 which extends in a height direction transversely and in particular perpendicular to the installation plane 26 in the direction of the waste container 194.

At least one fastening recess 226 is arranged on the edge wall 224 (see also Figures 7 and 8), which is open towards the installation plane 26.

The edge wall 224 is a wall which extends parallel to the corresponding longitudinal axis (transverse to a rotation axis of the main sweeping roller 190).

A hook, such as the hook of a quick release, can be positioned on the fastening recess 226. This allows an object (such as a bucket) to be positioned on the storage surface 220.

In the sweeper 180, in particular the storage surface 220 is a highest point of the sweeper 180 relative to the installation plane 26 with the exception of a push bar 228.

The use of the bridge 216 as a storage area 220 results in an optimized use of space on the sweeper 180.

The storage device 218 with the storage surface 220 is arranged between the housing 196, which is firmly connected to the chassis 182, and the channel device 210.

In relation to the height direction perpendicular to the installation plane 26, the waste container 194 is arranged between the installation plane 26 and the storage area 220. It can also be provided that the waste container 194 is positioned in this direction between the installation plane 26 and the suction fan device 198 in the housing 196.

The waste container 194 is also positioned between the filter device 212 and the installation level 26.

In principle, it is also possible for the channel device 210 to be designed accordingly and for the storage device 218 to be formed on the channel device 210. For example, the filter device 212 is then arranged on the housing 196.

When the sweeper 180 is in operation, a vacuum flow is provided by the suction fan device 198, which acts on the interior of the waste container 194. This vacuum flow primarily serves to minimize "dust distribution" into the environment during a sweeping process with the sweeper 180. When the sweeper 180 is cleaning with the rotating main sweeping roller 190, dust is generally swirled up, which can then be sucked away via the suction fan device 198. The suction fan device 198 primarily serves to suck up such swirled up dust and not necessarily primarily to suck up dust directly from a surface 24 to be cleaned.

In principle, it is also possible for the sweeper 180 to have the main sweeping roller 190 driven by a corresponding motor.

Otherwise, the sweeper 180 functions basically the same as the sweeper 10 with regard to the height adjustment of the main sweeper roller 190 and its distanced positioning from the installation plane in a first setting of the handle 192. Furthermore, the sweeper 180 functions basically the same as the sweeper 10 with regard to the storage device 218. List of reference symbols
