Description

[0001] Sweeper with storage area

[0002] 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 material container which is removably mounted on the chassis.

[0003] WO 2008 / 022699 A2 discloses a hand-guided 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.

[0004] CH 489 235 A discloses a manual pusher for waste collectors and floor cleaners with rotating brushes.

[0005] DE 12 25 684 A discloses a sweeper with dust extraction and an adjustable sweeping roller.

[0006] DE 10 2014 006 391 A1 discloses a sweeper with a collecting container for sweepings that can be attached to the rear of a housing.

[0007] EP 1 531 202 B1 discloses a sweeper comprising a housing, a debris hopper, and a sweeping roller covered by the housing, which sweeping roller is mounted on a height adjustment device for rotation about a pivot axis. The height adjustment device can be pivoted by means of an adjustment mechanism about a pivot axis aligned parallel to the pivot axis. The adjustment mechanism has a pivot arm which can be pivoted about the pivot axis, projects from the housing, and can be releasably locked in different pivot positions. 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, the pivot arm being fixed to the cross strut and projecting radially from the cross strut with respect to the pivot axis.

[0008] DE 10 2018 104 749 A1 discloses a sweeper comprising a chassis, at least one sweeping brush arranged on the chassis, and a height adjustment device assigned to the at least one sweeping brush and by means of which a height position of the at least one sweeping brush can be adjusted relative to the chassis.

[0009] DE 10 2018 104 744 A1 discloses a sweeper comprising a chassis, a rear wheel assembly arranged on the chassis, and a push bar pivotably mounted on the chassis. A footrest area is provided, which is arranged on the chassis in the region of the rear wheel assembly. Starting from a properly positioned sweeper on a base, an operator can step on the footrest and move the sweeper as a whole away from the base into a parking position by supporting the rear wheel assembly on the base.

[0010] The invention is based on the object of providing a sweeper of the type mentioned above which has advantageous operating characteristics.

[0011] This object is achieved according to the invention in the sweeper mentioned at the outset in that a depositing device with a depositing surface for one or more objects is provided, which is held by the chassis, wherein the depositing surface is parallel to the installation plane or is inclined at most at an angle of 10° to the installation plane.

[0012] One or more objects, such as a bucket, can be carried on the storage area when the sweeper is cleaning.

[0013] Furthermore, one or more objects can be positioned above the installation level on the sweeper when it is stored.

[0014] 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.

[0015] In principle, it is possible for the storage surface itself to be flat, or, more 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 object in question is usually supported against the storage device using elements that form the flat envelope.

[0016] It is advantageous if at least one of the following is provided: the storage area has a width in a width direction of 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 area has a surface area of ​​at least 400 cm 2 and in particular at least 500 cm 2on; 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 onto the storage surface from above and is supported by the storage surface with respect to the height direction downwards; the storage surface is continuous; at least one fastening recess is assigned to the storage surface.

[0017] This creates a correspondingly large storage area, which can accommodate, for example, a 10-liter household bucket or a 20-liter construction bucket. In specific examples, the storage area is approximately 550 cm 2 and 900 cm 2 .

[0018] The corresponding storage area allows an object to be supported downwards during sweeper operation (with or without cleaning mode). 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 setup level.

[0019] A continuous storage area results in optimized use of space, especially for storing a bucket, for example.

[0020] If the storage area is assigned at least one fastening recess, then deposited objects can be secured, if necessary, for example using quick-release fasteners or tensioning straps. 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 sweeper; the axis of rotation of the at least one main sweeping roller is parallel to a wheel axis of the rear wheel assembly; the push bar is arranged on the chassis 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; a pivot axis of the push bar is transverse and in particular perpendicular to a forward direction of travel of the sweeper; 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 assembly is oriented parallel to the installation plane.

[0021] This results in a structurally simple design with correspondingly simple operation.

[0022] It is particularly advantageous if the storage surface is equipped with an anti-slip device. This makes it more difficult for objects to slide off the storage surface, for example, when cleaning a sloped floor. In a structurally simple embodiment, the storage device has parallel, spaced-apart webs. The parallel, spaced-apart webs define an envelope, and in particular a flat envelope. The webs are designed to have an anti-slip effect.

[0023] 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.

[0024] This results in a structurally simple design.

[0025] It is also possible that other types of anti-slip devices such as anti-slip mats or the like are provided.

[0026] 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. This allows "cargo" to be secured on the storage area, for example, using a quick-release fastener or a tensioning strap. The fastening element takes 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.

[0027] It is advantageous if the storage area is bordered by an edge wall. This provides a wall on which one or more mounting 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 inclined relative to the direction of gravity.

[0028] 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 dirt hopper; 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 at least with 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 design results if the edge wall comprises a handle, which is in particular a handle of the dirt hopper. This allows the number of components to be kept low and results in simplified manufacturing.

[0029] If the edge wall is open towards the front of the sweeper, then liquid that has accumulated on the storage area can be easily drained away or liquid accumulation is prevented.

[0030] At least one storage opening for tools or the like can be easily positioned on the edge wall.

[0031] Fastening eyelets or recesses on the edge wall make it easy to secure "loads" on the storage surface.

[0032] It can be provided that the edge wall protrudes upwards from the storage area and / or downwards in a vertical 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.

[0033] In particular, the storage area 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 area is located above the at least one main sweeping roller in the height direction; the storage area is located above at least one side brush in the height direction; the storage area is located above a pivot axis of the push bar in the height direction, or is located below a pivot axis of the push bar in relation to the height direction; the storage area is located above the rear wheel device in relation to the height direction; the storage area is located at a highest point of the sweeper in relation to the height direction and outside the push bar.

[0034] This results in easy usability.

[0035] In one embodiment, the storage area is permanently connected to the chassis. For example, the storage area is arranged on the debris hopper or is mounted on a removable housing element.

[0036] In one embodiment, the storage surface is arranged on the waste hopper, with at least one of the following: the storage surface is formed on a wall of the waste hopper; an edge wall of the storage surface is formed in the waste hopper.

[0037] The hopper can then be used to transport one or more objects on the storage area if the hopper is properly attached to the chassis of the sweeper.

[0038] This makes it easy to implement a walled edge on the waste hopper, for example, to limit the storage area. It is also advantageous to have a handle on the waste hopper that limits the storage area. This results in optimized space utilization and simplified manufacturing of the sweeper.

[0039] In one embodiment, a suction fan device is provided, through which the interior of the debris container can be subjected to a vacuum flow, and a filter device is provided for the vacuum flow. During cleaning operation, at least one main sweeping roller of the sweeper generally stirs up dust, which can then enter the area surrounding the sweeper. The suction fan device can reduce such "dust impact" on the area surrounding the sweeper. As a rule, the primary task of the suction fan device is to keep the dust load in the environment low; it is not the primary task of the suction fan device to directly vacuum the area to be cleaned.

[0040] In one embodiment, the storage area is arranged or formed on a housing, wherein the housing is a housing for the suction fan device and / or a housing for the filter device. This allows for optimized use of components of the sweeper. If a suction fan device is provided, it is generally advantageous if the sweeping waste hopper is pressurized by the vacuum flow via an upper side of the sweeping waste hopper, wherein the upper side faces away from the installation plane. On this upper side, one or more openings are arranged via which a fluid-effective connection to the suction fan device is established 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 hopper in relation to a height direction perpendicular to the installation plane.Such components include a housing, which serves as a housing for the suction fan unit and / or a housing for the filter unit. This allows the corresponding housing to be used optimally for transporting one or more objects by appropriately designing the storage area.

[0041] In one embodiment, the storage surface is arranged on an openable cover of the housing. For example, the housing is a filter box, and the cover on which the storage surface is formed is a cover through which, after opening, a filter of the filter device can be inserted into or removed from the filter box.

[0042] It is advantageous if the housing has at least one mounting recess. For example, a hook from a quick-release fastener or a strap from a tensioning belt can be inserted into the mounting recess. This allows components of the housing to be used to secure cargo to the storage area with minimal manufacturing and design effort.

[0043] 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.

[0044] This results in optimized use of space.

[0045] Furthermore, it is particularly advantageous if at least one of the following is provided: the storage surface is arranged on a bridge which is positioned above the waste container in relation to a height direction; the filter device is arranged on a bridge which is positioned above the waste container in relation to a height direction.

[0046] As mentioned above, it is advantageous if one or more openings, through which a vacuum flow is coupled into the waste hopper, are located on the top side of the waste hopper, facing away from the installation plane. It is then advantageous to provide a bridge, through which the vacuum flow is then fed to the waste hopper. The bridge is then positioned vertically perpendicular to the installation plane above the waste hopper, resulting in a practical arrangement for a storage area for carrying one or more objects with the sweeper.

[0047] In one embodiment, the filter device is arranged on a bridge which is positioned above the debris container in relation to the height direction.

[0048] 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.

[0049] In an advantageous embodiment, a height adjustment device is provided, via which a height position of the rotational axis of the at least one main sweeping roller can be adjusted relative to the installation plane, and a handle is provided which can be pivoted relative to the chassis, which is mechanically coupled to the height adjustment device, and via which a height position of the rotational axis relative to the installation plane can be lockably adjusted 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 said end position protects the bristles of the at least one main sweeping roller. In the corresponding end position, they are then not subjected to any mechanical stress due to contact with a surface.This, in turn, allows the sweeper to be parked with its base level on the floor without placing any mechanical stress on at least one of the main sweeping rollers. This results in an extended service life. This also allows the storage area in a corresponding parking position of the sweeper, where the sweeper is parked above the base level on the floor, to be used as a storage space for one or more objects.

[0050] In particular, according to the invention, the waste container is used with a storage area for storing objects.

[0057] Figure 7 is a sectional view of the sweeper according to Figure 6; and

[0058] Figure 8 is an enlarged view of Report A according to Figure 7.

[0059] 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 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.

[0060] 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.

[0061] The sweeper 10 is mounted on a surface 24 to be cleaned (see Figure 3) via a rear wheel assembly 20 and a front wheel assembly 22. The rear wheel assembly 20 and the front wheel assembly 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, the mounting plane 26 coincides with the surface to be cleaned.

[0062] The rear wheel assembly 20 is arranged on the chassis 12 in the region of the rear end 16. The rear wheel assembly 20 has a right rear wheel 30 and a left rear wheel 32 relative 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 as to be rotatable 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 of travel 28. The wheel axis 36 is parallel to the installation plane 26.

[0063] The right rear wheel 30 and the left rear wheel 32 are each arranged laterally on the chassis 12. In one embodiment, they extend to the rear end 16 (see Figure 1).

[0064] In one embodiment, the front wheel assembly 22 is or includes a roller 38, in particular a steering roller. The front wheel assembly 22 with the (at least one) roller 38 is arranged in the region of the front end 14.

[0065] 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 support 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 that is centrally located between the right rear wheel 30 and the left rear wheel 32.

[0066] The roller 38 is rotatable about a roller axis. In the forward direction of travel 28 of the sweeper 10, this roller axis is parallel to the wheel axis 36. The wheel axis 36 is a fixed axis relative to the chassis 12. The position of the roller axis relative to the chassis 12 depends on the position of the roller 38 if it is designed as a steering roller.

[0067] 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 region of the rear end 16 and in particular in the region of the rear wheel assembly 20. Using the push bar 42, an operator standing on the floor 24 to be cleaned can guide and, in particular, push the sweeper 10 over the floor to be cleaned.

[0068] In one embodiment, no motor drive is provided for the sweeper 10 and the travel movement is operator-driven (via operator force).

[0069] In one embodiment, the push bar 42 can be pivoted about a pivot axis 44 relative to the chassis 12. A defined pivot position of the push bar 42 relative to the chassis 12 can be set continuously or in steps. This allows the push bar 42 to be pivoted for storage of the sweeper 10 such 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.

[0070] 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.

[0071] 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.

[0072] 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 vertical 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-apart second rod portion 50, which is pivotally connected to the chassis 12 in the region of the right rear wheel 30.

[0073] 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 at a proximal end portion. The third rod portion 52 is a primary support area for an operator who guides the sweeper 10 over the surface 24 to be cleaned.

[0074] 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 support 58 on which a plurality of bristles are arranged.

[0075] The rotation axis 56 is parallel to the installation plane 26. It is parallel to the wheel axis 36 and 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.

[0076] During sweeping operation of the sweeper 10, the bristles of the main sweeping roller 54 act on the surface 24 to be cleaned (cf. Figure 5; Figure 5 shows a position of the main sweeping roller 54 in which the latter touches the surface 24 to be cleaned with its bristles and thereby acts 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.

[0077] A swing arm assembly 60 is positioned on the chassis 12 via a pivot bearing 62. The pivot bearing 62 defines a rotation axis 64.

[0078] The rotation axis 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.

[0079] 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.

[0080] In the first area, the main sweeping roller 54 is held on the swinging device 60 so as to be rotatable about the rotation axis 56 via a corresponding roller pivot bearing.

[0081] Depending on the rotational position of the swing 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 installation plane 26. This will be explained in more detail below.

[0082] A height adjustment device 72 is formed via the swinging device 60, with which the height position of the main sweeping roller 54 of the installation plane 26 can be adjusted depending on the rotational position of the swinging device 60 about the rotation axis 64. It can be provided that a guide device is assigned to the swinging device 60 in order to guide it relative to the chassis 12 and thus the main sweeping roller 54.

[0083] In one embodiment, the rocker assembly comprises spaced-apart rocker elements that are interconnected, for example, at the third region 70. Between the spaced-apart rocker 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.

[0084] 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.

[0085] 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 80.

[0086] The housing 78 has a wall 82 as a boundary to the second region 76.

[0087] In particular, a pivot bearing for the main sweeping roller 54 is also arranged in the housing interior 80, allowing it to rotate about the rotation axis 56. Furthermore, the swinging device 60 with the pivot bearing 62 is arranged in the housing interior 80.

[0088] A handle 84 is provided for an operator to adjust the height of the main sweeping roller 54 relative 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 swinging device 60; the handle 84 is mechanically coupled to the swinging device 60 via the rod 86. The handle 84 is thus rotatable or pivotable relative to the chassis 12 via the rotation axis 64.

[0089] A track device 88 is located on the housing 78. The track device 88 serves to establish a specific rotational or pivoting position of the handle 84 relative to the chassis 12. It also indicates to an operator the rotational position of the handle 84 relative 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 plane 26.

[0090] The track device 88 comprises a circular track 90 with opposing circular track elements, between which lies a slot. The rod 86 extends through the slot.

[0091] A positive locking element 92 is located on the rod 86 outside the housing interior 80. This positive locking element 92 serves to define a pivoting position (rotational position) of the handle 84 on the circular path 90 and thereby also to define a specific rotational position of the swing arm device 60 relative to the chassis 12.

[0092] Counter elements 94, and in particular spaced-apart discrete elements 94, are arranged on the circular path 90. These correspond to the positive-locking element 92 such that, in certain discrete positions, the positive-locking element 92 can engage the counter element 94, thereby blocking the handle 84 from pivoting relative to the chassis 12. This, in turn, blocks the pivoting of the swinging device 60 about the rotation axis 64. This, in turn, means that a specific height position of the main sweeping roller 54 (relative to its rotation axis 56) relative to the installation plane 26 is fixed. The positive-locking element 92 is movably and, in particular, linearly displaceably guided on the rod 86.

[0093] In one embodiment, the form-locking element 92 is designed as a sleeve which is guided linearly displaceably on the rod.

[0094] The positive 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 positive locking element 92 against the housing 78 and thereby against the track device 88. When a certain position of the positive locking element 92 relative to the counter elements 94 is reached, a positive locking occurs, and the pivotability of the handle 84 (in any direction) is blocked.

[0095] An operator can release 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 so, the operator must overcome the spring force of the spring device 96. After releasing the positive locking between the positive locking element 92 and the counter elements 94, the operator can then pivot the handle 84 relative to the chassis 12 and then adjust the height position of the main sweeping roller 54 relative to the installation plane 26.

[0096] When the user no longer exerts force, the positive locking element 92 can move back toward the track device 88, and a positive locking can be ensured. As mentioned above, discrete positive locking positions of the handle 84 on the track device 88 are provided.

[0097] In this context, reference is made to EP 1 531 202 B1, which discloses a corresponding elastically prestressed handle. The handle 84 is pivotable relative to the chassis 12 about the rotation axis 64 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 swinging device 60 is positioned such that the main sweeping roller 54, with respect to its rotation axis 56, has the greatest distance from the installation plane 26 compared to all other positions.

[0098] 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 from the installation plane 26.

[0099] 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.

[0100] In one embodiment (Figures 3 to 6), the handle 84 is oriented relative to the rod 86 at an acute angle to the mounting plane 26. When pivoting out of the first end position 98, the angle between the handle 84 and the mounting plane 26 increases (which leads to a lowering of the rotation axis 56).

[0101] 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-locking element 92.

[0102] 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.

[0103] In a similar way, a stop can also be assigned to the second end position.

[0104] 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.

[0105] In the first end position 98, the main sweeping roller 54 is raised relative to the installation level 26.

[0106] In the first end position 98 of the handle 84 with the main sweeping roller 54 raised, the sweeper 10 can be guided over a floor surface without mechanical contact of the main sweeping roller 54 with the floor surface. The first end position 98 of the handle 84 provides a sort of shuttle operation.

[0107] Furthermore, in the first end position 98 of the handle 84, the main sweeper roller 54 can be "relieved." Its bristles 102 do not touch the ground on which the sweeper 10 is positioned. As a result, they do not experience any deformation. This relieves the load on them when not in use, thus fundamentally extending their service life.

[0108] Figures 1 to 3 show such a driving or storage state of the sweeper 10, in which the handle 84 is in its first end position 98, thereby spacing the main sweeping roller 54 from the installation plane 26. A distance exists between the tips of the bristles 102 and the installation plane 26. In Figure 3, a corresponding minimum distance is indicated by reference numeral 104.

[0109] Outside the first end position 98, the main sweeping roller 54 is lowered and touches the installation plane 26 in such a way that a surface 24 to be cleaned is touched (Figures 4, 5).

[0110] This means that bristles 102 are bent upon contact with the floor 24 to be cleaned. This is not shown in Figures 4 and 5 for illustrative reasons. The bristles 102 rest in a partial area against the surface 24 to be cleaned in order to be able to act on it mechanically.

[0111] 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 relative to the installation plane 26.

[0112] By adjusting the respective pivot position accordingly, the brush can be adapted to the condition of the surface 24 to be cleaned, and, for example, a contact pressure on the surface 24 to be cleaned can also be adjusted. Furthermore, bristle wear can be compensated for by selecting the appropriate pivot position.

[0113] The chassis 12 comprises a base support 106. The front wheel assembly 22 is mounted directly on the base support 106. The base support 106 has a plate-shaped configuration, at least in the second region 76 of the chassis 12.

[0114] A sweeping waste hopper 108 is releasably secured to the base support 106 at the second region 76 of the chassis 12. The sweeping waste hopper 108 serves to hold sweeping waste, which is conveyed into an interior 110 of the sweeping waste hopper 108 by the main sweeping roller 54. The sweeping waste hopper 108 is designed as a box. It comprises a wall 112 that surrounds the interior 110. The wall 112 is open at an end 114, which faces the housing 78 when the sweeping waste hopper 108 is mounted on the chassis 12. During sweeping operation of the sweeping machine 10, sweeping waste can be conveyed into the interior 110 via a corresponding opening 116 of the sweeping waste hopper 108. When the sweeping waste container 108 is removed from the sweeping machine 10, the sweeping waste container 108 can be emptied via the opening 116.

[0115] 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.

[0116] Opposite the bottom wall 118, the waste container 108 has a top wall 120.

[0117] 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 or faces the front end 14. The opening 116 on the debris container 108 is positioned opposite this front area 124.

[0118] In one embodiment, the bottom wall 118 and the top wall 120 are substantially straight. The front area 124 includes shoulders (see Figure 3). These serve to positively position the debris container 108 on the chassis 12 and also to provide recesses for mounting elements of the front wheel assembly 22.

[0119] 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 embodiment, this acute angle is approximately 70°. The wall 112 is adapted at the opening 116 to this inclination of the wall 82 of the housing 78. This allows the debris container 108, when mounted on the chassis 12, to be supported downwards on the wall 82 toward the installation plane 26.

[0120] A holding device, designated as a whole by 126, is arranged on the chassis 12 and holds the dirt hopper 108 to the chassis 12. This holding device 126 comprises the wall 82 and further form-locking elements, which ensure appropriate support of the dirt hopper 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 dirt hopper 108 from moving outward, when properly positioned on the chassis 12, in the transverse direction 34 (lateral form-locking elements 128) and in the longitudinal axis 18 toward the front end 14 (front form-locking element 130). The wall 82 of the housing 78 ensures that the outward movement toward the rear end 16 is blocked.

[0121] Furthermore, the chassis 12 with the second region 68 provides downward support. As mentioned, the wall 82 also provides downward support toward the installation plane 26. The front form-locking element 130 can also be designed to provide downward support.

[0122] The debris hopper 108 is positioned on the chassis 12 such 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. Furthermore, no screws or the like need to be loosened to remove the debris hopper.

[0123] The housing 78 has an opening 132 on the wall 82, which is assigned to the main sweeping roller 54. Sweepings can be conveyed through the opening 132 by the main sweeping roller 54 through the opening 116 into the sweepings container 108.

[0124] 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.

[0125] 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 sweeping material.

[0126] Sweepings are thrown into the opening 132 by the main sweeping roller 54. The ramp supports this throwing action. At the same time, it forms a skirt or boundary surface, which essentially prevents sweepings from being thrown by the main sweeping roller 54 below the base support 106 toward the roller 38.

[0127] In one embodiment, the ramp 134 is movable. It can be movably mounted on the chassis 12 and / or have inherent mobility through a corresponding construction from an elastic material such as a rubber material.

[0128] 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.

[0129] A side brush is held by an arm 138, in particular pivotable, relative to the chassis 12.

[0130] A broom holder 140 is mounted on the arm 138. A round brush 142 with corresponding bristles is mounted on the broom holder 140. The round brush is inclined, in particular, at a small, acute angle (for example, on the order of 30°) to the mounting plane 26.

[0131] The pivotable side arm 138 allows a lateral position of the corresponding side brush 136 to be determined. The arm 138 can be pivoted, in particular, toward the chassis 12 to provide a space-optimized storage position for the sweeper 12.

[0132] A free space 144 is formed between the installation plane 26 and the base support 106. The task of the side brushes 136 is to transport sweepings in such a way that they can be driven over the free space 144 and then thrown into the sweepings container 108 through the opening 132 by the main sweeping roller 54.

[0133] 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.

[0134] The sweeper 10 works as follows:

[0135] During cleaning operation, the sweeper 10 is positioned above the installation level 26 on the surface 24 to be cleaned. The push bar 42 is positioned so that an operator standing on the surface 24 to be cleaned can push the sweeper 10 across the surface 24 to be cleaned (using muscle power).

[0136] Before cleaning, 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-locking element 92 with corresponding counter-elements 94 engages 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 pivot 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.

[0137] An operator then pushes the sweeper 10 over the area 24 to be cleaned. The main sweeper roller 54 is rotatable about the rotation axis 56. A traveling 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 sweeping debris located on the area to be cleaned in front of the main sweeper roller 54 is carried along by it and thrown over the ramp 134 through the opening 132 into the sweeping debris container 108.

[0138] The sweeping machine 10 picks up sweeping material which is located below the base support 106 in front of the main sweeping roller 54.

[0139] A length of the main sweeping roller in a direction parallel to the rotation axis 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.

[0140] One or two side brushes 136 can initially pick up debris outside the "track" of the chassis 12 and convey it into this track. When the sweeper 10 passes over it, the main sweeping roller 54 can then also pick up this debris and throw it into the debris container 108.

[0141] The height adjustment device 72 with the handle 84 and the first end position 98, in which the main sweeping roller 54 is spaced from the installation plane 26 (so that none of the bristles 102 are adjacent to the installation plane 26), results in a "clean-free" sweeping operation of the sweeper 10. Such a sweeping operation is used, for example, to stow the sweeper or to specifically "switch off" the sweeping function of the main sweeping roller 54. Furthermore, when the sweeper 10 is parked, the main sweeping roller 54 is protected, as the bristles 102 are then not subjected to mechanical stress. Contact of bristles 102 with a floor leads to a bending of the bristles and thus to mechanical stress.

[0142] 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.

[0143] For example, bristle wear can also be compensated by adjusting the height setting.

[0144] 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.

[0145] 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 can be placed on the sweeper 10 and, in particular, can also be transported with the sweeper 10 during a travel movement of the sweeper 10.

[0146] In the sweeper 10 (Figures 1 to 5), the depositing device 148 is arranged or formed on the sweeping material container 108.

[0147] The storage device 148 comprises a storage surface 150. The storage surface 150 is flat, at least with respect to an envelope. This will be explained in more detail below.

[0148] 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.

[0149] In a specific example, the width B is 30 cm.

[0150] 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.

[0151] In a specific example, the length L is 30 cm.

[0152] Furthermore, the storage area 150 has a surface area of ​​at least 400 cm 2 and especially 500 cm 2 This area is at least approximately the product of the length L and the width B.

[0153] In a specific example, the area is 900 cm 2 .

[0154] In particular, the storage surface 150 is designed such that, for example, a 10-liter household bucket or a 20-liter 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 such that an object (such as a bucket) can be placed onto the storage surface 150 from above, and the storage surface 150 then supports the object downwards.

[0155] The storage surface 150 is configured, at least with respect to its envelope, parallel to the support plane 26 or oriented at a small, acute angle of no more than 10° to the support plane 26. This prevents the object from slipping, at least on a flat surface 24. An anti-slip device may additionally be provided, which is described in more detail below.

[0156] In the sweeper 10, the storage device 148 is formed on the debris container 108 and thereby on the ceiling wall 120. An outer side 152 of the ceiling wall 120 forms or encompasses the storage surface 150.

[0157] 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.

[0158] 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 parallel and spaced apart from 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 oriented at least approximately parallel to the transverse direction 34.

[0159] The end wall 160 faces the housing 78. The end wall 160 and the first lateral wall 156 and the second lateral wall 158 are configured to provide a continuous and, in particular, step-free transition from the debris hopper 108 to the housing 78 at its top when the debris hopper 108 is properly seated on the sweeping machine 10. The edge wall 154 is open toward the front end 14 (when the debris hopper 108 is seated on the sweeping machine 10); it is open away from the end wall 160. This allows, in particular, water that may accumulate on the storage surface 150 or would otherwise accumulate to flow forward (toward the front end 14).

[0160] The storage surface 150 lies between the first lateral wall 156, the end 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.

[0161] A distance between the end wall 116 and the opposite front end defines the length L.

[0162] Opposite the edge wall 154, the storage surface 150 is recessed.

[0163] A handle 162 is arranged on the edge wall 154 and on the end wall 160. The handle 162 comprises a bracket with a clearance 164 for the operator's fingers to pass through.

[0164] The dirt container 108 can be grasped via the handle 162 and removed from the sweeper 10 or inserted into the sweeper 10.

[0165] The edge wall 154 prevents objects positioned on the storage surface 150 from falling sideways and backwards.

[0166] The storage surface 150 is assigned a slip-preventing device 166. The slip-preventing device 166 serves to at least make it more difficult for objects placed on the storage surface 150 to slip off. In one embodiment, the slip-preventing device 166 comprises spaced-apart 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.

[0167] 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.

[0168] In such an embodiment, an envelope of the storage surface 150 is formed by an envelope surface on the webs 168.

[0169] The anti-slip device 168 may also have other designs, such as a slip-resistant mat which is fixedly or removably positioned between the walls 156, 158, 160.

[0170] In one embodiment, the storage surface 150 is assigned at least one fastening element, via which a fixation of objects positioned on the storage surface 150 (such as a bucket) can be achieved.

[0171] In one embodiment, a fastening recess 170 or fastening eyelet 170 is arranged on each of the first lateral wall 156 and the second lateral wall 158. Such a fastening recess 170 is an opening that is, in particular, continuous between an outer side of the edge wall 154 and a space above the storage surface 150.

[0172] For example, a hook of a quick-release fastener can be accommodated in such a fastening recess 170, or a tensioning strap can be threaded through it. In one embodiment, exactly one fastening recess 170 is arranged on each of 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, parallel to the transverse direction 34, or perpendicular to the longitudinal axis 18.

[0173] Several fastening recesses 170 can also be provided per lateral wall 156 or 158.

[0174] For example, a fastening recess or multiple fastening recesses can be arranged in the front area 124 of the waste container 108. A quick-release fastener can then be arranged between such a fastening recess and the handle 162 (with its free space 164), or a tensioning strap can be passed through. In such an embodiment, a cross-over guide of a tensioning strap (between a fastening recess in the front area 124 and a fastening recess 170 on a lateral wall 156 or 158) is also possible.

[0175] Furthermore, it is also possible for one or more storage openings 172 (Figure 1) to be arranged or formed on the edge wall 154. Such a storage opening 172 can accommodate, for example, a screwdriver or the like.

[0176] The storage surface 150 allows one or more objects, such as a bucket, to be carried during cleaning operation of the sweeper 10. Fastening elements 170 can be used to additionally secure such an object to prevent it from falling during a corresponding sweeping operation. Even when the sweeper 10 is parked and rests with the support surface 26 on a floor (in which case, in particular, the handle 84 is moved to the first end position 98), objects can be stored on the sweeper 10 via the storage surface 150.

[0177] The storage surface 150 is arranged on the sweeping machine 10 on the debris hopper 108. When the debris hopper 108 is fixed to the chassis 12, the storage surface 150 is located, relative to the vertical direction 46, in particular above the wheel axis 36 and above the rotation axis 56 of the main sweeping roller 54. Furthermore, the storage surface is then preferably located above the side brush(es) 136 relative to the vertical direction 56.

[0178] In the embodiment shown in Figure 1, the pivot axis 44 of the push bar 42 is located above the storage surface 150.

[0179] Another embodiment of a sweeper, shown in Figures 6 to 8 and designated 180, comprises a chassis 182 on which a rear wheel assembly 184, a front wheel assembly 186, side brushes 188, and a main sweeping roller 190 are arranged. The arrangement is basically the same as described above with reference to sweeper 10.

[0180] Furthermore, a height adjustment device is provided, which is basically designed identically to the above-described height adjustment device 72 of the sweeper 10. 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 sweeper 10.)

[0181] A removable dirt hopper 194 is mounted on the chassis 182.

[0182] 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 vacuum flow (suction flow).

[0183] 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.

[0184] 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.

[0185] The debris hopper is provided with an opening 208 on its upper side 206 (which faces away from the installation plane 26). When the debris hopper 194 is mounted on the sweeping machine 180, a channel device 210 is connected to the opening 208, which fluidically connects an interior of the debris hopper 194 (effective for a suction flow) to the suction fan device 198.

[0186] 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.

[0187] 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.

[0188] 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, it is connected downstream of the opening 208. The housing 214 forms a bridge 216 between the duct device 210 and the housing 196, which is fixedly mounted on the chassis 182.

[0189] In the area of ​​the housing 214, the dirt container 194 is spaced from this housing 214.

[0190] The combination of channel device 210 and housing 214 is designed such that the debris container 194 can be easily removed from the chassis 182 and reinserted with a corresponding solution for the connection of the channel device 210 to the opening 208 or the production of this connection.

[0191] 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 debris container 194.

[0192] The support surface 220 itself or an envelope lies parallel to the support plane 26 or at an acute angle of at most 10° to it.

[0193] 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 cm 2 on.

[0194] In a specific example, the length L is 24 cm, the width B is 23 cm and the area is 552 cm 2 .

[0195] 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 illustrated embodiment, the housing 214 has an edge wall 224, which extends in a vertical direction transversely and in particular perpendicularly to the installation plane 26 in the direction of the debris container 194.

[0196] 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.

[0197] 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).

[0198] A hook, such as the hook of a quick-release fastener, can be positioned on the mounting recess 226. This allows an object (such as a bucket) to be positioned on the storage surface 220.

[0199] In the case of 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.

[0200] Using the bridge 216 as a storage area 220 results in optimized use of space on the sweeper 180.

[0201] The storage device 218 with the storage surface 220 is arranged between the housing 196, which is fixedly connected to the chassis 182, and the channel device 210.

[0202] Relative to the vertical direction perpendicular to the installation plane 26, the debris container 194 is arranged between the installation plane 26 and the storage surface 220. It can also be provided that the debris container 194 is positioned in this direction between the installation plane 26 and the suction fan device 198 in the housing 196.

[0203] The debris container 194 is also positioned between the filter device 212 and the installation level 26.

[0204] 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.

[0205] During operation of the sweeper 180, a vacuum flow is generated by the suction fan device 198, which acts on the interior of the debris container 194. This vacuum flow primarily serves to minimize dust dispersion into the surrounding area during a sweeping operation with the sweeper 180. During cleaning operation of the sweeper 180 with the rotating main sweeping roller 190, dust is generally stirred up, which can then be extracted via the suction fan device 198. The suction fan device 198 primarily serves to extract such stirred up dust and not necessarily to directly extract dust from a surface 24 to be cleaned.

[0206] In principle, it is also possible for the sweeper 180 that the main sweeping roller 190 is driven by a corresponding motor.

[0207] Otherwise, the sweeper 180 functions in principle the same as the sweeper 10 with regard to the height adjustment of the main sweeping roller 190 and its distanced positioning from the installation plane in a first setting of the handle 192. Furthermore, the sweeper 180 functions in principle the same as the sweeper 10 with regard to the storage device 218. List of reference symbols
