Definitions

  • the invention relates to a hand-held soil cultivation device for cultivating soils by scrubbing, polishing or grinding.
  • a device for treating surfaces is known, in particular for cleaning and polishing, which provides a joint that is movable in at least two directions between a holding device and the base part.
  • This joint enables the user to adjust the handle height to the personal size of the user by tilting the holding device and to move the device back and forth in the processing direction, as well as to perform lateral movements with the device.
  • the joint is arranged laterally on the base part and the base part has protruding parts, the lateral mobility is limited.
  • a steam scrubbing machine is known with a handle part which is movable in the processing direction with respect to the base part and which has a water tank, a water pump, a heater and a steam distributor on the base part.
  • a vacuum cleaner unit also attached to the base part, comprising a suction space, a suction pump, a suction channel and a suction opening, is disclosed for dry cleaning.
  • back vacuum cleaners with a back unit and a support frame are known, in which the back unit comprises at least one suction pump and one suction space.
  • the back unit comprises at least one suction pump and one suction space.
  • an energy store for supplying energy to the pump can also be provided in the back unit.
  • the DE 196 22 856 A1 discloses a hand-operated surface scrubbing device which has at least one, preferably two disc brushes, and at least one roller brush, and which is moved supported on wheels. Furthermore, a suction strip is provided, which is preferably attached to the rear end of the cleaning device and which is connected to a receptacle for dirty water via a hose. A container for cleaning fluid is also attached to the surface scrubber.
  • this surface scrubbing device has the disadvantage that its weight is increased by the liquid container attached to the device itself, and that the wheels allow easy movement in a linear direction, but do not allow any real mobility in the lateral direction.
  • a lip for a mopping device which has projections on its one side surface along its length with non-protruding spaces between the projections extending upwards from the lower edge, the other side surface being smooth. If this lip is moved with its smooth side over a floor, it forms a seal with the floor that does not let water through. If the lip with the side face having projections is moved over the floor, water can flow through the aforementioned spaces. As a result, a suction unit consisting of two corresponding lips can absorb water in two directions, forwards and backwards.
  • the invention is based on the object of providing a soil cultivation device which, in addition to polishing or grinding, also enables wet cleaning and can be easily moved and operated by hand.
  • the object on which the invention is based is achieved by a soil cultivation device with the features of claim 1.

  • the machining direction of the base part can be pivoted parallel to the floor, even when the guide part is inclined, and enables corners or niches or under projections to be machined easily.
  • the bottom part can advantageously be rotated by the user parallel to the processing surface around the vertical axis of the bottom part by at least ⁇ 270 °.
  • the mobility enables cleaning both in the forward and backward direction, as well as in the lateral direction, even if the guide part is inclined about the first joint axis to the vertical axis of the base part, whereby the soil cultivation device can always be moved in the processing direction, which is a prerequisite for represents a regular intake of the liquid.
  • the bottom part is advantageously supported exclusively on the tool for soil cultivation. As a result, the mobility of the base part is not restricted by a support device.
  • the tool for soil cultivation consists of at least two counter-rotating and essentially horizontally rotating drive plates with processing attachments.
  • the opposing rotation of two drive plates attached symmetrically around the center of the soil cultivation device leads to an even number of drive plates in a force-neutral state of the base part and enables easy, resistance-free guidability of the base part by means of the guide part over the ground.
  • the processing attachments can advantageously be brushes, plates for pads or grinding wheels.
  • the soil cultivation device can be used for a wide variety of jobs such as polishing, scrubbing or grinding.
  • the soil cultivation device has at least one energy store for supplying the tool.
  • An energy store attached to the soil cultivation device makes it possible to dispense with the power cable to an external energy supply, which enables a greater radius of movement of the soil cultivation device. This makes it possible, for example, to use the soil cultivation device for cleaning stairwells.
  • the at least one energy store is advantageously attached to the base part and / or to the guide part.
  • the at least one energy store is advantageously attached in a removable manner.
  • the bottom part advantageously has a loosely suspended splash guard which is movable in height relative to the bottom part and which surrounds the tool for soil cultivation at least in sections.
  • the splash guard Due to the loose, vertically movable arrangement of the splash guard, it can always sit flat on the processing surface regardless of the movements of the bottom part and thus avoid splashing water.
  • the bottom part has a liquid supply.
  • the tillage device can also be used for wet scrubbing.
  • the liquid is advantageously supplied in an area below the base part within the splash guard and / or centrally through the drive plate and the processing attachments. This ensures that the liquid is evenly distributed over the entire surface.
  • a liquid tank for the liquid supply is provided.
  • the soil cultivation device does not have to be connected to an external water supply, which would restrict the range of motion of the soil cultivation device.
  • the liquid tank is advantageously attached to the base part or to the guide part above the further joint. As a result, the mobility of the bottom part is restricted as little as possible by means of the guide part.
  • the liquid tank attached to the guide part is elongated along the guide part.
  • the liquid is as close as possible to the guide part, so that the weight of the liquid makes it as difficult as possible to move the guide part.
  • the container for the absorbed liquid is advantageously attached to the guide part above the further joint and is elongated along the guide part.

Description

Technisches GebietTechnical area

Die Erfindung betrifft ein handgeführtes Bodenbearbeitungsgerät zur Bearbeitung von Böden durch Schrubben, Polieren oder Schleifen.The invention relates to a hand-held soil cultivation device for cultivating soils by scrubbing, polishing or grinding.

Stand der TechnikState of the art

Aus der EP 0 978 249 ist eine Vorrichtung zur Behandlung von Oberflächen bekannt, insbesondere zum Reinigen und Polieren, die ein in mindestens zwei Richtungen bewegliches Gelenk zwischen einer Haltevorrichtung und dem Bodenteil vorsieht. Dieses Gelenk ermöglicht es dem Benutzer, durch Schrägstellen der Haltevorrichtung die Griffhöhe der persönlichen Größe des Benutzers anzugleichen und die Vorrichtung in Bearbeitungsrichtung vor und zurück zu bewegen, sowie seitliche Bewegungen mit der Vorrichtung auszuführen.From the EP 0 978 249 a device for treating surfaces is known, in particular for cleaning and polishing, which provides a joint that is movable in at least two directions between a holding device and the base part. This joint enables the user to adjust the handle height to the personal size of the user by tilting the holding device and to move the device back and forth in the processing direction, as well as to perform lateral movements with the device.

Da das Gelenk seitlich am Bodenteil angeordnet ist und das Bodenteil hervorstehende Teile aufweist, ist die seitliche Beweglichkeit allerdings eingeschränkt.Since the joint is arranged laterally on the base part and the base part has protruding parts, the lateral mobility is limited.

Aus der DE 203 02 630 U1 ist eine Dampfschrubbmaschine mit einem in Bearbeitungsrichtung gegenüber dem Bodenteil beweglichen Griffteil bekannt, die einen Wassertank, eine Wasserpumpe, einen Erhitzer und einen Dampfverteiler am Bodenteil aufweist. Als vorteilhafte Weiterbildung wird zum trockenen Reinigen eine ebenfalls am Bodenteil angebrachte Staubsaugereinheit umfassend einen Einsaugraum, eine Einsaugpumpe, einen Saugkanal und eine Einsaugöffnung offenbart.From the DE 203 02 630 U1 a steam scrubbing machine is known with a handle part which is movable in the processing direction with respect to the base part and which has a water tank, a water pump, a heater and a steam distributor on the base part. As an advantageous further development, a vacuum cleaner unit also attached to the base part, comprising a suction space, a suction pump, a suction channel and a suction opening, is disclosed for dry cleaning.

Weiterhin sind Rücken-Staubsauger mit einer Rückeneinheit und einem Tragegestell bekannt, bei denen die Rückeneinheit zumindest eine Einsaugpumpe und einen Einsaugraum umfasst. Zur Erhöhung der Beweglichkeit kann auch ein Energiespeicher zur Energieversorgung der Pumpe in der Rückeneinheit vorgesehen sein.Furthermore, back vacuum cleaners with a back unit and a support frame are known, in which the back unit comprises at least one suction pump and one suction space. To increase the mobility, an energy store for supplying energy to the pump can also be provided in the back unit.

Die DE 196 22 856 A1 offenbart ein von Hand geführtes Flächenschrubbgerät, das mindestens eine, vorzugsweise zwei Tellerbürsten, sowie mindestens eine Walzbürste aufweist, und das auf Rädern abgestützt bewegt wird. Weiterhin ist eine Absaugleiste vorgesehen, die vorzugsweise am hinteren Ende des Reinigungsgerätes angebracht ist, und die über einen Schlauch mit einem Aufnahmebehälter für Schmutzwasser verbunden ist. Ein Behälter für Reinigungsflüssigkeit ist ebenfalls an dem Flächenschrubbgerät angebracht.the DE 196 22 856 A1 discloses a hand-operated surface scrubbing device which has at least one, preferably two disc brushes, and at least one roller brush, and which is moved supported on wheels. Furthermore, a suction strip is provided, which is preferably attached to the rear end of the cleaning device and which is connected to a receptacle for dirty water via a hose. A container for cleaning fluid is also attached to the surface scrubber.

Dieses Flächenschrubbgerät hat allerdings den Nachteil, dass sein Gewicht durch die am Gerät selbst angebrachten Flüssigkeitsbehälter erhöht wird, und dass die Räder zwar ein leichtes Bewegen in linearer Richtung zulassen, aber keine wirkliche Beweglichkeit in seitlicher Richtung ermöglichen.However, this surface scrubbing device has the disadvantage that its weight is increased by the liquid container attached to the device itself, and that the wheels allow easy movement in a linear direction, but do not allow any real mobility in the lateral direction.

Aus der EP 0 560 523 A2 ist eine Lippe für ein Wischgerät bekannt, die auf ihrer einen Seitenfläche Vorsprünge entlang ihrer Länge mit nicht hervorstehenden Räumen zwischen den Vorsprüngen aufweist, die sich vom unteren Rand nach oben erstrecken, wobei die andere Seitenfläche glatt ist. Wird diese Lippe mit ihrer glatten Seite über einen Boden bewegt, so bildet sie eine Abdichtung mit dem Boden, die kein Wasser durchlässt. Wird die Lippe mit der Vorsprünge aufweisenden Seitenfläche über den Boden bewegt, so kann Wasser durch die genannten Zwischenräume fließen. Dadurch kann eine Saugeinheit bestehend aus zwei entsprechenden Lippen in zwei Richtungen, vor und zurück, Wasser aufnehmen.From the EP 0 560 523 A2 a lip for a mopping device is known which has projections on its one side surface along its length with non-protruding spaces between the projections extending upwards from the lower edge, the other side surface being smooth. If this lip is moved with its smooth side over a floor, it forms a seal with the floor that does not let water through. If the lip with the side face having projections is moved over the floor, water can flow through the aforementioned spaces. As a result, a suction unit consisting of two corresponding lips can absorb water in two directions, forwards and backwards.

Aus der DE 35 42 631 A1 ist ein Reinigungsgerät für Hartflächen mit zwei parallelen Zylinderbürsten, die gegensinnig rotierend angetrieben sind, mit einer Sprüheinrichtung und mit einer Absaugung bekannt.From the DE 35 42 631 A1 a cleaning device for hard surfaces with two parallel cylinder brushes, which are driven to rotate in opposite directions, with a spray device and with a suction device is known.

Aus der US 4 499 624 A ist ein portables Poliergerät mit zueinander gegensinnig rotierenden Walzen bekannt. Entsprechendes gilt für die US 4 570 278 A .From the U.S. 4,499,624 A a portable polishing device with rollers rotating in opposite directions is known. The same applies to the U.S. 4,570,278 A .

Der Erfindung liegt die Aufgabe zugrunde, ein Bodenbearbeitungsgerät bereitzustellen, welches neben Polieren oder Schleifen auch das Nassreinigen ermöglicht und dabei von Hand leicht beweglich und bedienbar ist.The invention is based on the object of providing a soil cultivation device which, in addition to polishing or grinding, also enables wet cleaning and can be easily moved and operated by hand.

Darstellung der ErfindungPresentation of the invention

Die der Erfindung zugrundeliegende Aufgabe wird durch ein Bodenbearbeitungsgerät mit den Merkmalen von Anspruch 1 gelöst.The object on which the invention is based is achieved by a soil cultivation device with the features of claim 1.

Das weitere Gelenk bildet mit dem ersten Gelenk ein Kardangelenk und ermöglicht es einem Benutzer, das Bodenteil innerhalb der Bearbeitungsebene zu drehen, auch wenn das Führungsteil um die erste Gelenkachse zu der Hochachse des Bodenteils schräg gestellt ist, was eine große Beweglichkeit des Bodenteils ermöglicht. So ist die Bearbeitungsrichtung des Bodenteils auch bei schräg gestelltem Führungsteil parallel zum Boden schwenkbar und ermöglicht das einfache Bearbeiten von Ecken oder Nischen oder unter Vorsprüngen.The further joint forms a universal joint with the first joint and enables a user to rotate the base part within the working plane, even if the guide part is inclined about the first joint axis to the vertical axis of the base part, which enables great mobility of the base part. The machining direction of the base part can be pivoted parallel to the floor, even when the guide part is inclined, and enables corners or niches or under projections to be machined easily.

Prinzipiell ist mittels eines solchen Kardangelenks auch bei schräg gestelltem Führungsteil ein beliebiges Verdrehen des Bodenteils um seine Hochachse möglich.In principle, any rotation of the bottom part about its vertical axis is possible by means of such a universal joint even with the guide part positioned at an angle.

Vorteilhafterweise kann das Bodenteil vom Benutzer aus parallel zur Bearbeitungsfläche um die Hochachse des Bodenteils um mindestens ±270° gedreht werden.The bottom part can advantageously be rotated by the user parallel to the processing surface around the vertical axis of the bottom part by at least ± 270 °.

Dies ermöglicht es dem Benutzer, das Bodenbearbeitungsgerät erst in einer von dem Benutzer weg zeigenden Richtung zu betreiben, dann das Bodenteil um 180° zu drehen und das Bodenbearbeitungsgerät in eine auf den Benutzer hin zeigende Richtung zurück zu bewegen. Weiterhin kann der Benutzer das Bodenteil, während er es wieder zu sich hin bewegt, auch noch weiter drehen, hat also auch bei auf den Benutzer zu gerichteter Bewegung des Bodenteils weiterhin die volle Beweglichkeit in seitlicher Richtung. Diese Beweglichkeit ermöglicht ein einfaches Reinigen von Ecken, Nischen oder Vorsprüngen, beispielsweise unter Treppen oder Tischen. Weiterhin ermöglicht die Beweglichkeit das Reinigen sowohl in Vorwärts- und Rückwärtsrichtung, als auch in seitlicher Richtung, auch wenn das Führungsteil um die erste Gelenkachse zu der Hochachse des Bodenteils schräg gestellt ist, wobei das Bodenbearbeitungsgerät immer in Bearbeitungsrichtung bewegt werden kann, was eine Voraussetzung für eine reguläre Aufnahme der Flüssigkeit darstellt.This enables the user to first operate the soil cultivation device in a direction pointing away from the user, then to rotate the bottom part by 180 ° and to move the soil cultivation device back in a direction pointing towards the user. Furthermore, the user can turn the base part even further while he is moving it towards himself again, so he also has to move towards the user Directed movement of the bottom part continues to have full mobility in the lateral direction. This mobility makes it easy to clean corners, niches or protrusions, for example under stairs or tables. Furthermore, the mobility enables cleaning both in the forward and backward direction, as well as in the lateral direction, even if the guide part is inclined about the first joint axis to the vertical axis of the base part, whereby the soil cultivation device can always be moved in the processing direction, which is a prerequisite for represents a regular intake of the liquid.

Vorteilhafterweise stützt sich das Bodenteil ausschließlich auf dem Werkzeug für die Bodenbearbeitung ab. Dadurch wird die Beweglichkeit des Bodenteils nicht durch eine Stützvorrichtung eingeschränkt.The bottom part is advantageously supported exclusively on the tool for soil cultivation. As a result, the mobility of the base part is not restricted by a support device.

Weiter gemäß der Erfindung besteht das Werkzeug für die Bodenbearbeitung aus mindestens zwei sich gegenläufig und im Wesentlichen horizontal drehenden Treibtellern mit Bearbeitungsaufsätzen.Further according to the invention, the tool for soil cultivation consists of at least two counter-rotating and essentially horizontally rotating drive plates with processing attachments.

Die Gegenläufigkeit von jeweils zwei symmetrisch um die Mitte des Bodenbearbeitungsgeräts angebrachten Treibtellern führt bei einer geraden Anzahl von Treibtellern zu einem kräfteneutralen Zustand des Bodenteils und ermöglicht eine leichte, widerstandfreie Führbarkeit des Bodenteils mittels des Führungsteils über den Boden.The opposing rotation of two drive plates attached symmetrically around the center of the soil cultivation device leads to an even number of drive plates in a force-neutral state of the base part and enables easy, resistance-free guidability of the base part by means of the guide part over the ground.

Vorteilhafterweise können die Bearbeitungsaufsätze Bürsten, Teller für Pads oder Schleifscheiben sein.The processing attachments can advantageously be brushes, plates for pads or grinding wheels.

Dadurch kann das Bodenbearbeitungsgerät für verschiedenste Arbeiten wie Polieren, Schrubben oder Schleifen eingesetzt werden.This means that the soil cultivation device can be used for a wide variety of jobs such as polishing, scrubbing or grinding.

Weiter gemäß der Erfindung weist das Bodenbearbeitungsgerät zur Versorgung des Werkzeugs mindestens einen Energiespeicher auf.Further according to the invention, the soil cultivation device has at least one energy store for supplying the tool.

Durch einen an dem Bodenbearbeitungsgerät angebrachten Energiespeicher kann auf das Leistungskabel zu einer externen Energieversorgung verzichtet werden, wodurch ein höherer Bewegungsradius des Bodenbearbeitungsgeräts ermöglicht wird. Dies macht es beispielsweise möglich, dass Bodenbearbeitungsgerät zum Reinigen von Treppenhäusern einzusetzen.An energy store attached to the soil cultivation device makes it possible to dispense with the power cable to an external energy supply, which enables a greater radius of movement of the soil cultivation device. This makes it possible, for example, to use the soil cultivation device for cleaning stairwells.

Vorteilhafterweise ist der mindestens eine Energiespeicher am Bodenteil und/oder am Führungsteil angebracht.The at least one energy store is advantageously attached to the base part and / or to the guide part.

Vorteilhafterweise ist der mindestens eine Energiespeicher abnehmbar angebracht.The at least one energy store is advantageously attached in a removable manner.

Dadurch kann der Energiespeicher gewechselt und eine längere Betriebsdauer ermöglicht werden. Weiterhin ist es dadurch möglich, den Energiespeicher zu entfernen und damit das Gewicht des Bodenteils und/oder des Führungsteils zu verringern, wenn das Bodenbearbeitungsgerät beispielsweise an eine externe Energieversorgung angeschlossen ist, so dass das Bodenteil leichter mittels des Führungsteils bewegt und geführt werden kann.This allows the energy storage device to be changed and a longer operating time to be made possible. Furthermore, it is thereby possible to remove the energy store and thus to reduce the weight of the base part and / or the guide part when the soil cultivation device is connected, for example, to an external energy supply is, so that the bottom part can be moved and guided more easily by means of the guide part.

Vorteilhafterweise weist das Bodenteil einen lose aufgehängten, in der Höhe gegenüber dem Bodenteil beweglichen Spritzschutz auf, welcher das Werkzeug für die Bodenbearbeitung zumindest abschnittsweise umgibt.The bottom part advantageously has a loosely suspended splash guard which is movable in height relative to the bottom part and which surrounds the tool for soil cultivation at least in sections.

Durch das lose, in der Höhe bewegliche Anordnen des Spritzschutzes kann dieser unabhängig von den Bewegungen des Bodenteils immer eben auf der Bearbeitungsfläche aufsitzen und so Spritzwasser vermeiden.Due to the loose, vertically movable arrangement of the splash guard, it can always sit flat on the processing surface regardless of the movements of the bottom part and thus avoid splashing water.

Weiter gemäß der Erfindung weist das Bodenteil eine Flüssigkeitszuführung auf. Dadurch kann das Bodenbearbeitungsgerät auch zum Nassschrubben eingesetzt werden.According to the invention, the bottom part has a liquid supply. This means that the tillage device can also be used for wet scrubbing.

Vorteilhafterweise erfolgt die Flüssigkeitszuführung in einem Bereich unterhalb des Bodenteils innerhalb des Spritzschutzes und/oder mittig durch die Treibteller und die Bearbeitungsaufsätze hindurch. Dies gewährleistet eine gleichmäßige flächige Verteilung der Flüssigkeit.The liquid is advantageously supplied in an area below the base part within the splash guard and / or centrally through the drive plate and the processing attachments. This ensures that the liquid is evenly distributed over the entire surface.

Weiter gemäß der Erfindung ist ein Flüssigkeitstank für die Flüssigkeitszuführung vorgesehen. Dadurch muss das Bodenbearbeitungsgerät nicht an eine externe Wasserversorgung angeschlossen werden, was den Bewegungsradius des Bodenbearbeitungsgeräts einschränken würde.Further according to the invention, a liquid tank for the liquid supply is provided. As a result, the soil cultivation device does not have to be connected to an external water supply, which would restrict the range of motion of the soil cultivation device.

Vorteilhafterweise ist der Flüssigkeitstank an dem Bodenteil oder an dem Führungsteil oberhalb des weiteren Gelenks angebracht. Dadurch wird die Beweglichkeit des Bodenteils mittels des Führungsteils möglichst wenig eingeschränkt.The liquid tank is advantageously attached to the base part or to the guide part above the further joint. As a result, the mobility of the bottom part is restricted as little as possible by means of the guide part.

Vorteilhafterweise ist der an dem Führungsteil angebrachte Flüssigkeitstank entlang des Führungsteils länglich ausgeformt. Dadurch befindet sich die Flüssigkeit möglichst nah am Führungsteil, so dass das Gewicht der Flüssigkeit das Bewegen des Führungsteils möglichst wenig erschwert.Advantageously, the liquid tank attached to the guide part is elongated along the guide part. As a result, the liquid is as close as possible to the guide part, so that the weight of the liquid makes it as difficult as possible to move the guide part.

Vorteilhafterweise ist der Behälter für die aufgenommene Flüssigkeit an dem Führungsteil oberhalb des weiteren Gelenks angebracht und länglich entlang des Führungsteils ausgeformt.The container for the absorbed liquid is advantageously attached to the guide part above the further joint and is elongated along the guide part.

Dadurch wird die durch die zwei Gelenke ermöglichte Beweglichkeit des Bodenteils nicht eingeschränkt und die Beweglichkeit des Führungsteils durch das Gewicht der aufgenommenen Flüssigkeit möglichst wenig belastet.As a result, the mobility of the base part made possible by the two joints is not restricted and the mobility of the guide part is burdened as little as possible by the weight of the liquid taken up.

AusführungsbeispielEmbodiment

In der Fig. 1 ist ein erfindungsmäßiges Bodenbearbeitungsgerät dargestellt. Ein Bodenteil 1 kann über ein Führungsteil 2 und ein Griffteil 3 von einem Benutzer P geführt werden, wobei das Führungsteil 2 mit dem Bodenteil 1 über zwei Gelenke verbunden ist, die zusammen ein Kardangelenk bilden. Ein erstes Gelenk 4 besteht aus einem Bügel 5 und einer in Fig. 3 dargestellten, am Bodenteil 1 angebrachten Achse 30, wobei eine Gelenkachse G1, die in Fig. 3 dargestellt ist, entlang der Achse 30 parallel zu einer Bearbeitungsfläche B und quer zur Bearbeitungsrichtung 6 verläuft und der Bügel 5 entsprechend der durch den Pfeil 7 angezeigten Richtung um die Achse G1 bewegt werden kann. Ein zweites Gelenk 8 verbindet das Führungsteil 2 mit dem Bügel 5, wobei eine Gelenkachse G2 quer zur Gelenkachse G1 verläuft und das Führungsteil um die Achse G2 entsprechend der durch den Pfeil 9 angezeigten Richtung bewegt werden kann. Dies ermöglicht es dem Benutzer P, auch bei schräg gestelltem Führungsteil 2 das Bodenteil 1 parallel zur Bearbeitungsfläche B um seine Hochachse A1 zu drehen. Damit kann der Benutzer P die Bearbeitungsrichtung 6 parallel zur Bearbeitungsfläche B drehen. Der Benutzer P kann das Bodenteil beispielsweise zuerst von sich weg und dann nach einem Drehen des Bodenteils um 180° auf sich zu bewegen, wobei die Bearbeitungsrichtung 6 entsprechend erst von ihm weg und dann auf ihn zu läuft.In the Fig. 1 a soil cultivation device according to the invention is shown. A bottom part 1 can be guided by a user P via a guide part 2 and a handle part 3, the guide part 2 being connected to the bottom part 1 via two joints which together form a universal joint. A first joint 4 consists of a bracket 5 and an in Fig. 3 shown, attached to the bottom part 1 axis 30, wherein a hinge axis G1, the in Fig. 3 is shown, runs along the axis 30 parallel to a machining surface B and transversely to the machining direction 6 and the bracket 5 can be moved around the axis G1 in the direction indicated by the arrow 7. A second joint 8 connects the guide part 2 to the bracket 5, a joint axis G2 running transversely to the joint axis G1 and the guide part being able to be moved about the axis G2 in the direction indicated by the arrow 9. This enables the user P to rotate the base part 1 parallel to the processing surface B about its vertical axis A1 even when the guide part 2 is inclined. The user P can thus rotate the machining direction 6 parallel to the machining surface B. The user P can, for example, first move the bottom part away from himself and then after rotating the bottom part 180 ° towards himself, the processing direction 6 accordingly first moving away from him and then towards him.

Das erfindungsgemäße Bodenbearbeitungsgerät weist einen Flüssigkeitstank 10 für die Flüssigkeitszuführung auf, der beispielsweise oberhalb des zweiten Gelenks 8 am Führungsteil 2 angebracht sein kann und über eine Flüssigkeitszuführung 11 mit dem Bodenteil 1 verbunden ist.The soil cultivation device according to the invention has a liquid tank 10 for the liquid supply, which is for example above the second joint 8 on the Guide part 2 can be attached and is connected to the bottom part 1 via a liquid feed 11.

Bei der dargestellten Ausführungsform ist es vorteilhaft, den Flüssigkeitstank 10 so zu gestalten, dass er zumindest teilweise um das Führungsteil 2 herum reicht und seine Ausmaße in der Richtung quer zum Führungsteil 2 möglichst gering sind, während die Ausmaße entlang des Führungsteils 2 größer sein können. Dadurch wird das Bewegen des Führungsteils 2 möglichst wenig durch die sich im Flüssigkeitstank 10 ebenfalls bewegende Flüssigkeit erschwert.In the embodiment shown, it is advantageous to design the liquid tank 10 so that it extends at least partially around the guide part 2 and its dimensions are as small as possible in the direction transverse to the guide part 2, while the dimensions along the guide part 2 can be larger. As a result, the movement of the guide part 2 is made as little difficult as possible by the fluid that is also moving in the fluid tank 10.

Das Bodenbearbeitungsgerät weist einen Spritzschutz 12 auf, der außenseitig am Bodenteil 1 angeordnet ist und möglichst weit um das Bodenteil 1 herumreicht. Der Spritzschutz 12 weist zur Bearbeitungsfläche B hin Borsten oder Lippen auf und ist so angeordnet, dass er in seiner Höhe über der Bearbeitungsfläche B gegenüber dem Bodenteil 1 beweglich ist, so dass er mit seinen Borsten oder Lippen immer auf der Bearbeitungsfläche B aufsitzt.The soil cultivation device has a splash guard 12 which is arranged on the outside of the base part 1 and extends as far as possible around the base part 1. The splash guard 12 has bristles or lips towards the processing surface B and is arranged in such a way that its height above the processing surface B can be moved relative to the base part 1, so that its bristles or lips are always seated on the processing surface B.

Weiterhin weist das Bodenteil 1 an seiner Unterseite eine Flüssigkeitsaufnahme 13 auf, die quer zur Bearbeitungsrichtung 6 möglichst weit über die Breite des Bodenteils 1 reicht und in Bewegungsrichtung 6 hinter dem Bodenteil 1 angeordnet und am Spritzschutz 12 befestigt ist, ohne die in der Höhe freie Beweglichkeit des Spritzschutzes 12 gegenüber dem Bodenteil 1 einzuschränken.Furthermore, the bottom part 1 has a liquid receptacle 13 on its underside, which extends transversely to the machining direction 6 as far as possible over the width of the bottom part 1 and is arranged in the direction of movement 6 behind the bottom part 1 and attached to the splash guard 12, without the freedom of movement in height of the splash guard 12 with respect to the bottom part 1.

Die baulich getrennte Saugeinheit ist in dem dargestellten Ausführungsbeispiel als eine von einem Benutzer P am Körper zu befestigende Einheit 15 ausgebildet. Diese am Körper zu befestigende Einheit 15 ist weiterhin als Rückeneinheit ausgebildet und über einen Schlauch 14 mit der Flüssigkeitsaufnahme 13 verbunden. Die Rückeneinheit 15 weist einen Behälter 16 für die von der Bodenfläche B aufgenommene Flüssigkeit sowie eine Saugturbine 17 auf, die mit einem Motor 18 angetrieben werden kann, der ebenfalls in der Rückeneinheit 15 angeordnet ist. Zur Energieversorgung ist der Motor 18 über ein Leistungs- und gegebenenfalls auch über ein Steuerkabel 19 direkt an das Bodenteil 1 angeschlossen, wobei ein Anschluss am Rückenteil 15 oder am Bodenteil 1 vorgesehen sein kann, so dass diese Verbindung zwischen Rückenteil 15 und Bodenteil 1 gelöst werden kann.In the exemplary embodiment shown, the structurally separate suction unit is designed as a unit 15 to be attached to the body by a user P. This unit 15 to be fastened to the body is also designed as a back unit and is connected to the liquid receptacle 13 via a hose 14. The back unit 15 has a container 16 for the liquid taken up by the bottom surface B and a suction turbine 17 which can be driven by a motor 18 which is also arranged in the back unit 15. For the energy supply, the motor 18 is connected directly to the base part 1 via a power cable and possibly also via a control cable 19, whereby a connection can be provided on the back part 15 or on the base part 1 so that this connection between the back part 15 and the base part 1 is released can.

In einer weiteren Ausführungsvariante kann das Leistungs- und Steuerkabel 19 auch über das Griffteil 3 und/oder das Führungsteil zum Bodenteil 1 geführt werden, oder es kann ein Anschluss am Griffteil 3 oder am Führungsteil 2 vorgesehen sein, an den das Leistungs- und Steuerkabel 19 angeschlossen werden kann.In a further embodiment variant, the power and control cable 19 can also be guided via the handle part 3 and / or the guide part to the base part 1, or a connection can be provided on the handle part 3 or on the guide part 2 to which the power and control cable 19 can be connected.

Es kann auch vorteilhaft sein, den Behälter 16 für die von der Bodenfläche B aufgenommene Flüssigkeit beispielsweise an dem Führungsteil 2 anzuordnen und über je einen Schlauch mit der Flüssigkeitsaufnahme 13 und der Saugturbine 17 zu verbinden, da so ein sehr kurzer Saugweg möglich ist, wodurch sich die effektive Saugleistung der Saugturbine 17 verbessert. Hierbei ist es vorteilhaft, den Behälter 16 für die aufgenommene Flüssigkeit länglich entlang des Führungsteils 2 auszuformen, so dass sich die aufgenommene Flüssigkeit immer möglichst nah an dem Führungsteil 2 befindet und dadurch die Beweglichkeit des Führungsteils 2 nicht unnötig durch das Gewicht der aufgenommenen Flüssigkeit belastet wird.It can also be advantageous to arrange the container 16 for the liquid absorbed by the bottom surface B, for example, on the guide part 2 and to connect it to the liquid receptacle 13 and the suction turbine 17 via a hose each, since this enables a very short suction path, which results in the effective suction power of the Suction turbine 17 improved. It is advantageous here to shape the container 16 for the absorbed liquid elongated along the guide part 2 so that the absorbed liquid is always as close as possible to the guide part 2 and the mobility of the guide part 2 is not unnecessarily burdened by the weight of the absorbed liquid .

Dadurch, dass sowohl der Flüssigkeitstank für die Flüssigkeitszuführung als auch der Behälter 16 für die aufgenommene Flüssigkeit am Führungsteil 2 und/oder am Bodenteil 1 angeordnet werden, bleibt das Gesamtgewicht der Bodeneinheit aus Bodenteil 1 und Führungsteil 2 während der Bodenbearbeitung im Wesentlichen konstant. Dies ermöglicht es, den Druck auf das mindestens eine Werkzeug 31 zur Bodenbearbeitung konstant zu halten und so eine konstante und zuverlässige Funktionsweise zu garantieren.Because both the liquid tank for the liquid supply and the container 16 for the absorbed liquid are arranged on the guide part 2 and / or on the base part 1, the total weight of the base unit made up of base part 1 and guide part 2 remains essentially constant during soil cultivation. This makes it possible to keep the pressure on the at least one tool 31 for soil cultivation constant and thus to guarantee a constant and reliable mode of operation.

Weiterhin ist es möglich, den Behälter für die aufgenommene Flüssigkeit und den Flüssigkeitstank für die Flüssigkeitszuführung gleich auszuformen, also nur eine Form für beide Behälter zu wählen, wodurch die Produktionskosten des Bodenbearbeitungsgeräts verringert werden können.Furthermore, it is possible to shape the container for the absorbed liquid and the liquid tank for the liquid supply in the same way, that is to say to choose only one shape for both containers, whereby the production costs of the soil cultivation device can be reduced.

Weiterhin hat das Vorsehen des Behälters 16 für die aufgenommene Flüssigkeit am Bodenteil 1 und/oder am Führungsteil 2 den Vorteil, dass beim Lösen des Schlauchs, der den Behälter 16 für die aufgenommene Flüssigkeit mit der Saugturbine 17 verbindet, keine im Schlauch verbliebene Restflüssigkeit auslaufen kann, da die Flüssigkeit in dem tiefer liegenden Behälter 16 für die aufgenommene Flüssigkeit verbleibt.Furthermore, the provision of the container 16 for the absorbed liquid on the base part 1 and / or on the guide part 2 has the advantage that when the hose connecting the container 16 for the absorbed liquid to the suction turbine 17 is loosened, no residual liquid remaining in the hose can run out , since the liquid remains in the lower-lying container 16 for the absorbed liquid.

Die Rückeneinheit 15 weist ein Tragegestell 20 auf, wodurch es von dem Benutzer P komfortabel auf dem Rücken getragen werden kann.The back unit 15 has a support frame 20, as a result of which it can be carried comfortably on the back by the user P.

Für andere Ausführungsformen der am Körper zu befestigenden Einheit 15 können entsprechend an die Art des Tragens angepasste Tragegestelle vorgesehen sein und auch die Form der am Körper zu befestigenden Einheit ist an die Art des Tragens anzupassen. Eine Rückeneinheit kann beispielsweise länglich flach ausgebildet werden und mit einem Rucksack-ähnlichen Tragegestell versehen werden. Soll die am Körper zu befestigende Einheit um die Hüfte getragen werden, muss sie entsprechend kleiner ausgebildet und mit einem Hüftgurt versehen werden. Eine vor dem Bauch zu befestigende Einheit kann beispielsweise nicht so lang ausgebildet werden, wie dies bei einer Rückeneinheit möglich ist.For other embodiments of the unit 15 to be fastened to the body, support frames adapted to the type of wearing can be provided, and the shape of the unit to be fastened to the body is also to be adapted to the type of wearing. A back unit can, for example, have an elongated flat design and be provided with a backpack-like carrying frame. If the unit to be attached to the body is to be worn around the waist, it must be made correspondingly smaller and provided with a hip belt. For example, a unit to be fastened in front of the stomach cannot be made as long as is possible with a back unit.

In der Fig. 2 ist die Rückeneinheit aus Fig. 1 im Querschnitt dargestellt. Der Behälter 16 für die aufgenommene Flüssigkeit weist im Bodenbereich eine Auslassöffnung 21 auf, an die ein Auslassschlauch 22 oder auch ein Auslassstutzen mit einem Verschluss 23 angebracht ist. Der Auslassschlauch 22 und der Verschluss 23 sind so angeordnet, dass die Absperrarmatur 23 vom Benutzer P bedient und die aufgenommene Flüssigkeit aus dem Behälter 16 für die aufgenommene Flüssigkeit über den Ablassschlauch 22 abgelassen werden kann, während der Benutzer P die Rückeneinheit 15 auf dem Rücken trägt. Um die Bewegungsfreiheit des Benutzers P beim Ablassen der aufgenommenen Flüssigkeit zu erhöhen, kann für den Schlauch 14 ein Anschluss mit einer Kupplung vorgesehen sein, so dass diese Verbindung der Rückeneinheit 15 mit dem Bodenteil 1 gelöst werden kann. Alternativ kann auch ein Stutzen am Bodenteil 1 vorgesehen sein. Der Schlauch oder Stutzen am Bodenteil kann auch als Siphon ausgebildet sein, der verhindert, dass Restwasser ausläuft.In the Fig. 2 the back unit is off Fig. 1 shown in cross section. The container 16 for the absorbed liquid has an outlet opening 21 in the bottom area, to which an outlet hose 22 or also an outlet nozzle with a closure 23 is attached. The outlet hose 22 and the closure 23 are arranged in such a way that the shut-off valve 23 is operated by the user P and the absorbed liquid from the container 16 for the absorbed liquid via the drainage tube 22 can be lowered while the user P carries the back unit 15 on his back. In order to increase the freedom of movement of the user P when draining the absorbed liquid, a connection with a coupling can be provided for the hose 14 so that this connection of the back unit 15 to the base part 1 can be released. Alternatively, a connection piece can also be provided on the base part 1. The hose or nozzle on the bottom part can also be designed as a siphon, which prevents residual water from leaking out.

Die Rückeneinheit 15 weist in dieser Ausführungsvariante eine Energieversorgung 24 für den Motor 18 und eine Schalter 25 zum Ein- und Ausschalten der Saugturbine 17 auf.In this embodiment variant, the back unit 15 has an energy supply 24 for the motor 18 and a switch 25 for switching the suction turbine 17 on and off.

Weiterhin ist in der Fig. 2 das Bodenteil 1 des erfindungsmäßigen Bodenbearbeitungsgeräts von unten ohne einen Bearbeitungsaufsatz dargestellt. Durch einen Motor 26 werden zwei Treibteller 27 gegenläufig und im Wesentlichen horizontal angetrieben. Am Spritzschutz 12, der in dieser Ausführungsvariante ringförmig um das gesamte Bodenteil 1 herumreicht, ist die Flüssigkeitsaufnahme 13 so angebracht, dass die freie Bewegung des Spritzschutzes 12 in seiner Höhe über der Bearbeitungsfläche gegenüber dem Bodenteil 1 nicht beeinträchtigt ist. Die Flüssigkeitsaufnahme 13 weist eine Saugleiste 49 mit zwei in Bearbeitungsrichtung 6 zueinander beabstandeten Dichtlippen 28, 29 auf, wobei die in Bearbeitungsrichtung 6 vordere Lippe 28 möglichst geriffelt ist oder Öffnungen aufweist, durch welche beim Bewegen des Bodenteils 1 in Bearbeitungsrichtung 6 die aufzunehmende Flüssigkeit in den Bereich x zwischen den beiden Dichtlippen 28, 29 gelangen kann. Dieser Bereich x der Saugleiste 49 zwischen den Dichtlippen 28, 29 ist über den Schlauch 14 mit der als Rückeneinheit 15 ausgebildeten Saugeinheit verbunden, so dass Flüssigkeit aufgesaugt werden kann.Furthermore, in the Fig. 2 the bottom part 1 of the inventive soil cultivation device shown from below without a processing attachment. A motor 26 drives two drive plates 27 in opposite directions and essentially horizontally. On the splash guard 12, which in this embodiment variant extends in a ring around the entire bottom part 1, the liquid receptacle 13 is attached in such a way that the free movement of the splash guard 12 in its height above the processing surface with respect to the bottom part 1 is not impaired. The liquid receptacle 13 has a suction bar 49 with two sealing lips 28, 29 spaced apart from one another in the machining direction 6, the front lip 28 in the machining direction 6 being as corrugated as possible or having openings through which, when the bottom part 1 is moved in the machining direction 6, the liquid to be absorbed into the Area x can get between the two sealing lips 28, 29. This area x of the suction strip 49 between the sealing lips 28, 29 is connected via the hose 14 to the suction unit designed as a back unit 15, so that liquid can be sucked up.

Die Fig. 3 zeigt einen Querschnitt des Bodenteils 1 mit Führungsteil 2 und Griffteil 3 des Bodenbearbeitungsgeräts aus Fig. 1. Dargestellt ist wieder das Gelenk 4, das aus dem Bügel 5 und der Achse 30, die am Bodenteil 1 befestigt ist, besteht, wobei das Gelenk 4 um die Gelenkachse G1 entsprechend der durch den Pfeil 7 angezeigten Richtung bewegt werden kann.the Fig. 3 shows a cross section of the bottom part 1 with guide part 2 and handle part 3 of the soil cultivation device from Fig. 1 . The joint 4 is shown again, which consists of the bracket 5 and the axis 30, which is fastened to the base part 1, the joint 4 being able to be moved about the joint axis G1 in the direction indicated by the arrow 7.

Weiterhin weist das Bodenteil 1 ein Werkzeug 31 für die Bodenbearbeitung auf, welches die Treibteller 27 und Bearbeitungsaufsätze 32 wie beispielsweise dargestellte Bürsten umfasst, wobei sich das Bodenteil 1 ausschließlich auf dem Werkzeug 31 abstützt. Die auf den Treibtellern 27 angeordneten Bearbeitungsaufsätze 32 werden mit dem Motor 26 angetrieben, der durch einen Energiespeicher 33 versorgt wird. Dieser Energiespeicher 33 ist möglichst abnehmbar am Bodenteil 1 befestigt und kann beispielsweise über ein Leistungskabel aufgeladen werden. Der Motor 26 weist möglichst ebenfalls ein Leistungskabel 35 auf, was es ermöglicht, auf den Energiespeicher 33 zu verzichten und den Motor 26 an eine externe Energieversorgung anzuschließen.The bottom part 1 also has a tool 31 for soil cultivation, which comprises the drive plate 27 and processing attachments 32 such as the brushes shown, the bottom part 1 being supported exclusively on the tool 31. The processing attachments 32 arranged on the drive plates 27 are driven by the motor 26, which is supplied by an energy store 33. This energy store 33 is attached to the base part 1 so that it can be removed as possible and can be charged, for example, via a power cable. If possible, the motor 26 also has a power cable 35, which makes it possible to dispense with the energy store 33 and to connect the motor 26 to an external energy supply.

Die Flüssigkeitszuführung 11 der Flüssigkeit aus dem Flüssigkeitstank 10 erfolgt mittig durch die Treibteller 27 hindurch.The liquid supply 11 of the liquid from the liquid tank 10 takes place centrally through the drive plate 27.

Der Spritzschutz 12 kann mit mindestens einem über das Bodenteil 1 reichenden Bügel 36 lose mit dem Bodenteil 1 verbunden sein, so dass er während des Bearbeitens in der Höhe, also in der Richtung des Pfeils 37, frei beweglich ist, aber beim Anheben des Bodenteils 1 über den mindestens einen Bügel 36 mit dem Bodenteil 1 verbunden bleibt. Dadurch kann der Benutzer P das Bodenteil 1 und den Spritzschutz 12 gleichzeitig anheben und versetzen und muss den Spritzschutz 12 nicht noch zusätzlich bewegen.The splash guard 12 can be loosely connected to the base part 1 with at least one bracket 36 reaching over the base part 1, so that it is freely movable in height during processing, i.e. in the direction of the arrow 37, but when the base part 1 is lifted remains connected to the base part 1 via the at least one bracket 36. As a result, the user P can lift and move the base part 1 and the splash guard 12 at the same time and does not have to move the splash guard 12 additionally.

Der Energiespeicher zur Versorgung des die Saugturbine antreibenden Motors kann auch am Führungsteil angeordnet werden, wobei der Energiespeicher vorteilhafterweise unterhalb des Tanks 19, aber oberhalb des Gelenks 8 angebracht wird.The energy store for supplying the motor driving the suction turbine can also be arranged on the guide part, the energy store advantageously being attached below the tank 19 but above the joint 8.

In Fig. 4 sind weiter Ausführungsvarianten des Werkzeugs 31 für die Bodenbearbeitung dargestellt. Die Fig. 4A zeigt einen Treibteller 27 mit einem Bearbeitungsaufsatz 32 in Form eines Tellers 48 für Pads 38, und in Fig. 4B ist ein Treibteller 27 mit einer Schleifscheibe 39 als Bearbeitungsaufsatz dargestellt. Die Fig. 4C zeigt ein Bodenteil 1 eines erfindungsmäßigen Bodenbearbeitungsgeräts, das an seiner Unterseite Walzen 40 mit Borsten 41 als Werkzeug 32 für die Bodenbearbeitung aufweist.In Fig. 4 further variants of the tool 31 for soil cultivation are shown. the Figure 4A shows a drive plate 27 with a processing attachment 32 in the form of a plate 48 for pads 38, and FIG Figure 4B a drive plate 27 is shown with a grinding wheel 39 as a processing attachment. the Figure 4C shows a bottom part 1 of a soil cultivation device according to the invention, which has rollers 40 with bristles 41 on its underside as a tool 32 for soil cultivation.

In Fig. 5A, B ist dargestellt, wie das Bodenteil 1 des erfindungsgemäßen Bodenbearbeitungsgeräts bei schräg gestelltem Führungsteil 2 mittels der Gelenke 4 und 8 um die Hochachse A1 des Bodenteils 1, die im Wesentlichen senkrecht auf der Bearbeitungsfläche B steht, gedreht werden kann. Durch Drehen des Griffteils 3 um 90° um eine Längsachse A2 des Führungsteils 2 wird das Bodenteil ebenfalls um 90° um die Hochachse A1 gedreht, wobei der Bügel 5 dabei von einer gegen die erste Bearbeitungsrichtung 6 schräg gestellten Ausgangslage um die Achse G1 in eine Lage parallel zur Achse A1 gebracht wird und das Führungsteil 2 um die weitere Gelenkachse G2 von einer anfänglichen Ausrichtung parallel zu einer Längsachse A3 des Bügels 5 in eine Ausrichtung schräg zu der Längsachse A3 des Bügels 5 bewegt wird. Von dieser in Fig. 5B dargestellten Lage aus kann das Bodenteil 1 durch Drehen des Griffteils 3 um weitere 90° ebenfalls um weitere 90° gedreht werden, so dass die Bearbeitungsrichtung 6, die ursprünglich in Richtung von dem Benutzer P weg zeigt, nun zu dem Benutzer P hin gerichtet ist, entsprechend der von Pfeil 6' angezeigten Richtung.In Figure 5A , B shows how the bottom part 1 of the soil cultivation device according to the invention can be rotated by means of the joints 4 and 8 around the vertical axis A1 of the bottom part 1, which is essentially perpendicular to the work surface B, with the guide part 2 inclined. By rotating the handle part 3 by 90 ° around a longitudinal axis A2 of the guide part 2, the base part is also rotated by 90 ° around the vertical axis A1, with the bracket 5 moving from a starting position inclined against the first machining direction 6 to a position around the axis G1 is brought parallel to the axis A1 and the guide part 2 is moved about the further hinge axis G2 from an initial alignment parallel to a longitudinal axis A3 of the bracket 5 to an alignment oblique to the longitudinal axis A3 of the bracket 5. From this in Figure 5B from the position shown, the bottom part 1 can also be rotated by a further 90 ° by turning the handle part 3 by a further 90 °, so that the processing direction 6, which originally points away from the user P, is now directed towards the user P, according to the direction indicated by arrow 6 '.
