Description

Die Erfindung betrifft einen Staubsauger des Upright-Typs mit einem Oberkörper, welcher mit einem Griff ausgestattet ist, mit einer Bodeneinheit, welche durch ein Fahrwerk auf der zu reinigenden Fläche bewegbar ist, und mit einem in der Bodeneinheit angeordneten Motorgebläse zur Erzeugung eines die zu reinigende Fläche wirkenden Unterdrucks, wobei Oberkörper und Bodeneinheit mittels eines Kippgelenks um eine im Gebrauchszustand horizontale Achse zueinander verschwenkbar ausgebildet sind, und wobei das Fahrwerk wenigstens ein im hinteren Bereich der Bodeneinheit angeordnetes Rad umfasst.The invention relates to a vacuum cleaner Upright type with a torso, which is equipped with a handle, with a ground unit, which is movable by a chassis on the surface to be cleaned, and with an arranged in the ground unit motor fan to produce one to be cleaned Surface acting negative pressure, wherein the upper body and bottom unit are formed by a tilting joint about a horizontal axis in use horizontal pivot, and wherein the chassis comprises at least one arranged in the rear region of the ground unit wheel.

Ein Staubsauger gemäß dem Oberbegriff des Anspruchs 1 ist z.B. aus GB-A-2410178 bekannt.A vacuum cleaner according to the preamble of claim 1 is made, for example GB-A-2410178 known.

Im Folgenden werden drei Staubsaugertypen beschrieben, die sich hinsichtlich ihres Aufbaus und ihrer Bedienung unterscheiden. Als gemeinsame Merkmale besitzen alle ein motorgetriebenes Gebläse, einen Staubsammelraum und eine oder mehrere an den jeweiligen Verwendungszweck angepasste Bodenbearbeitungseinrichtungen.The following describes three types of vacuum cleaner that differ in their construction and operation. As common features all have a motor-driven blower, a dust collection room and one or more adapted to the particular purpose tillage equipment.

Der Bodenstaubsauger besitzt ein Gehäuse, welches auf Rollen und/oder Gleitkufen auf dem zu bearbeitenden Boden verfahrbar ist. In dem Gehäuse sind das Motorgebläse und der Staubsammelbehälter angeordnet. Die Bodenbearbeitungseinrichtung - hier Bodendüse genannt - ist über einen Saugschlauch, evtl. mit zwischengeschaltetem Saugrohr, mit dem Staubsammelraum verbunden. Das Gehäuse wird während des Saugvorgangs durch Zug am Saugrohr in die gewünschte Position gebracht.The vacuum cleaner has a housing which is movable on rollers and / or skids on the ground to be processed. In the housing, the engine fan and the dust collector are arranged. The soil treatment device - here called floor nozzle - is connected via a suction hose, possibly with an intermediate suction pipe, with the dust collection chamber. The housing is brought into the desired position during the suction process by pulling on the suction tube.

Beim Handstaubsauger sind ebenfalls das Motorgebläse und der Staubsammelbehälter in einem Gehäuse angeordnet. Vom Gehäuse erstreckt sich auf der einen Seite ein Saugrohr, welches eine Bodendüse mit dem Staubsammelbehälter verbindet, und auf der anderen Seite ein Handgriff, mit dem das Gehäuse in die gewünschte Position manövriert wird.In the hand vacuum cleaner, the motor fan and the dust collector are also arranged in a housing. From the housing extends on one side of a suction pipe, which connects a floor nozzle with the dust collector, and on the other hand, a handle with which the housing is maneuvered into the desired position.

Uprights besitzen nicht einen so streng gegliederten Aufbau wie die beiden vorgenannten Typen. Wesentliches Merkmal eines Uprights ist eine verfahrbare Bodeneinheit, welche einen Oberkörper mit einem großen Staubsammelbehälter trägt. Die beiden Teile sind schwenkbar zueinander gelagert und meist in einer Parkposition festsetzbar, in der der Oberkörper annähernd senkrecht steht, wenn sich die Bodeneinheit in Gebrauchstellung auf einem waagerechten Boden befindet. In dieser Position steht der Upright selbsttätig. Während des Saugvorgangs wird diese Arretierung aufgehoben und der Oberkörper um einen gewissen Winkel in eine Arbeitsposition gekippt. Der Schwenkwinkel hängt einerseits von der Größe des Benutzers und andererseits vom jeweiligen Gebrauch ab. Ein Griff am Oberkörper dient zum Führen des gesamten Geräts. Das Motorgebläse kann an verschiedenen Stellen angeordnet sein. Es ist beispielsweise aus der WO 2007/008770 A2 bekannt, das Gebläse direkt am Oberkörper zu haltern. Dies verschlechtert den Bedienungskomfort, weil dieses schwere Bauteil ein Moment um den Kipppunkt verursacht, welchem der Benutzer während des gesamten Saugvorgangs entgegenwirken muss. Ein weiterer Nachteil des Uprights gemäß WO 2007/008770 A2 besteht darin, dass dieser nur schwer aus einer geraden Fahrtrichtung in kurvenförmige Bahnen bewegbar ist. Aus der WO 2004/014209 A1 und aus der EP 0 708 613 A1 ist es bekannt, das Gebläse als separate Baueinheit auszubilden. Durch einen Drehpunkt zwischen dem Oberkörper und dem oberen Bereich des Gebläses ( EP 0 708 613 A1 ) bzw. durch die Lagerung des Gebläses in einem drehbaren, kugelförmigen Gehäuse ( WO 2004/014209 A1 ) wird eine verbesserte Manövrierfähigkeit erreicht, weil der Upright nun in der Lage ist, Kurvenbewegungen auszuführen. Es sind auch Uprights bekannt, bei denen das Motorgebläse in der Bodeneinheit angeordnet ist. Bei diesen erfolgt die gelenkige Verbindung zwischen Bodeneinheit und Oberkörper durch ein scharnierartiges Gebilde. Die Luftführung erfolgt durch flexible Schläuche, die sich von der Bodeneinheit zum Oberkörper erstrecken.Uprights do not have such a rigorous structure as the two types mentioned above. An essential feature of an upright is a movable floor unit, which carries a torso with a large dust collector. The two parts are pivotally mounted to each other and usually fixable in a parking position in which the upper body is approximately vertical when the ground unit is in the use position on a horizontal floor. In this position, the upright is automatic. During the suction process, this locking is released and tilted the upper body by a certain angle in a working position. The swivel angle depends on the one hand on the size of the user and on the other hand from the respective use. A handle on the upper body is used to guide the entire device. The engine fan may be located at various locations. It is for example from the WO 2007/008770 A2 known, the blower directly on To support upper body. This worsens the ease of use, because this heavy component causes a moment around the tipping point, which the user must counteract during the entire suction process. Another disadvantage of the upright according to WO 2007/008770 A2 is that it is difficult to move from a straight direction in curved paths. From the WO 2004/014209 A1 and from the EP 0 708 613 A1 It is known to form the blower as a separate unit. Through a pivot point between the upper body and the upper area of the blower ( EP 0 708 613 A1 ) or by the mounting of the blower in a rotatable, spherical housing ( WO 2004/014209 A1 ), improved maneuverability is achieved because the upright is now able to perform cornering movements. There are also known Uprights in which the engine fan is arranged in the ground unit. In these, the articulated connection between the floor unit and the upper body by a hinge-like structure. The air is routed through flexible hoses that extend from the floor unit to the upper body.

Um dem Benutzer neben dem Saugbetrieb mit der Bodeneinheit zusätzliche Handhabungsmöglichkeiten zu bieten, bei denen er beispielsweise höhergelegene Objekte absaugen kann, besitzt die Luftführung eine Schnittstelle und strömungsmäßig hinter der Schnittstelle einen als Schlauch oder Schlauch-Rohr-Kombination ausgebildeten Bestandteil. Dabei wird in den meisten Fällen ein Rohrstück in einer Steckaufnahme gehalten. Nach dem Herausnehmen des Rohrstücks aus der Steckaufnahme können auf dem saugseitigen Ende unterschiedliche Saugvorsätze platziert werden und die so entstandene Anordnung kann wie bei einem herkömmlichen Bodenstaubsauger benutzt werden. Dies erfolgt in der Regel dann, wenn der Upright in der Parkposition abgestellt ist. Es besteht der Wunsch, dass der Upright in dieser Position verbleibt und auch bei leichtem Zug am Schlauch nicht umkippt. Aus der WO 2004/014209 A1 sind zwei Alternativen bekannt, um die Standfestigkeit eines Uprights in der Parkposition zu erhöhen. Bei einer ersten Variante (Figuren 1 und 2) sind die Hinterräder am Oberkörper gehaltert und werden beim Schwenken des Oberkörpers in eine aufrechte Position nach hinten bewegt. Eine solche Anordnung der Hinterräder ist nur bei kleinen Bodeneinheiten ohne Sauggebläse möglich. Bei einer zweiten Variante (Figur 6) ist eine zusätzliche Standvorrichtung vorgesehen, welche in der Parkposition die Standfläche vergrößert. Dies erhöht den konstruktiven Aufwand.To provide the user in addition to the suction with the ground unit additional handling options in which he can aspirate, for example, higher-altitude objects, the air duct has an interface and fluid behind the interface designed as a hose or hose-tube combination component. In this case, a piece of pipe is held in a plug-in receptacle in most cases. After removing the tube piece from the plug-in receptacle different suction attachments can be placed on the suction end and the resulting arrangement can be used as in a conventional vacuum cleaner. This is usually done when the upright is parked in the park position. There is a desire that the Upright remains in this position and does not tip over even with a slight pull on the hose. From the WO 2004/014209 A1 Two alternatives are known to increase the stability of a Uprights in the parking position. In a first variant ( Figures 1 and 2 ), the rear wheels are supported on the upper body and are moved when pivoting the upper body in an upright position to the rear. Such an arrangement of the rear wheels is only possible with small ground units without suction fan. In a second variant ( FIG. 6 ) An additional stand device is provided, which increases the footprint in the parking position. This increases the design effort.

Zur Erhöhung der Standsicherheit ist es außerdem bekannt, den Upright mit einer Bodeneinheit auszustatten, welche permanent eine sehr große Standfläche besitzt. Hierunter leidet die Manövrierfähigkeit.To increase the stability, it is also known to equip the Upright with a ground unit, which permanently has a very large footprint. This suffers the maneuverability.

Der Erfindung stellt sich somit das Problem bei einem Staubsauger der eingangs genannten Art einerseits eine gute Manövrierfähigkeit im Fahrbetrieb und andererseits eine hohe Standsicherheit in der Parkposition zu gewährleisten.The invention thus provides the problem in a vacuum cleaner of the type mentioned on the one hand to ensure good maneuverability while driving and on the other hand, a high stability in the parking position.

Erfindungsgemäß wird dieses Problem durch einen Staubsauger mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention this problem is solved by a vacuum cleaner with the features of claim 1. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.

Die mit der Erfindung erreichbaren Vorteile werden dadurch erreicht, dass das Rad mittels einer schwenkbaren Halterung an der Bodeneinheit befestigt ist, wobei die Schwenkachse der Halterung von der Drehachse des Rads entfernt liegt, und dass am Kippgelenk und im Bereich der Halterung Mittel vorhanden sind, welche bei einem Schwenken des Oberkörpers in Bezug auf die Bodeneinheit derart zusammenwirken, dass ein Schwenken der Halterung mit dem Rad verursacht wird. Hierdurch wird in der Parkposition auf einfache Weise die Standfläche erhöht, ohne dass der Benutzer eine manuelle Verstellung vornehmen muss. Dabei ist es zweckmäßig, wenn die Mittel am Kippgelenk und im Bereich der Halterung derart wirken, dass ein Schwenken des Oberkörpers in eine aufrechte Stellung eine Schwenkbewegung des Rads nach hinten verursacht, so dass der Abstand zwischen dem Rad und dem vorderen Bereich der Bodeneinheit vergrößert wird.The achievable with the present invention advantages are achieved in that the wheel is fixed by means of a pivotal mount on the ground unit, wherein the pivot axis of the holder is remote from the axis of rotation of the wheel, and that means are provided on the tilting joint and in the region of the support upon pivoting of the upper body with respect to the ground unit cooperate such that a pivoting of the holder is caused with the wheel. As a result, in the parking position easily increases the footprint, without the user must make a manual adjustment. It is expedient if the means on the tilting joint and in the region of the holder act such that a pivoting of the upper body in an upright position causes a pivoting movement of the wheel to the rear, so that the distance between the wheel and the front portion of the bottom unit is increased ,

Standsicherheit, Manövrierfähigkeit und Stabilität werden dadurch verbessert, dass die Räder so weit nach hinten schwenkbar sind, dass die Projektion des Schwerpunkts des Staubsaugers auf die zu reinigende Fläche innerhalb der Standfläche der Bodeneinheit liegt, und/oder dass zwei Hinterräder vorgesehen sind, die durch eine Achse miteinander verbunden sind, und/oder dass im vorderen Bereich der Bodeneinheit mindestens eine Laufrolle angeordnet ist. Noch mehr Standfestigkeit wird erreicht, wenn vor den Laufrollen Stützmittel angeordnet sind und wenn die Halterung und ihr Schwenkweg derart dimensioniert sind, dass das Rad in der aufrechten Position des Oberköpers nach unten schwenkt, bis es die Standfläche der Bodeneinheit von der (den) Laufrolle(n) auf die Stützmittel verlagert.Stability, maneuverability and stability are improved by pivoting the wheels so far backwards that the projection of the center of gravity of the vacuum cleaner lies on the surface to be cleaned within the standing surface of the ground unit, and / or by providing two rear wheels which are provided by a Axle are connected to each other, and / or that at least one roller is arranged in the front region of the bottom unit. Even more stability is achieved when supporting means are arranged in front of the rollers and when the holder and its pivoting path are dimensioned such that the wheel pivots downwards in the upright position of the upper body until it reaches the floor unit's footprint by the roller (s). n) shifted to the support means.

Der Bedienkomfort wird dadurch erhöht, dass die Bewegung, die der Oberkörper beim Aufrichten in die Parkposition vollführt, zum Schwenken der Räder in die hintere Position genutzt wird. Bei einem Upright, bei dem das Kippgelenk durch ein gabelfömiges Bauteil gebildet wird, wobei die Gabelenden die Schwenkachse (X) des Kippgelenks bilden und der Gabelsteg am Oberköper gehalten wird, ist dies dadurch möglich, dass die am Kippgelenk angeordneten Mittel zum Verursachen des Schwenkens der Halterung mindestens ein an einem Gabelende angeordnetes Zahnsegment umfassen. Die Mittel im Bereich der Halterung können dann einen Achsträger und ein auf die Halterung einwirkendes Stellrad umfassen. Das Rad kann sowohl in der aufrechten Stellung des Oberkörpers als auch in einer Endstellung in der geschwenkten Position des Oberkörpers verriegelt sein. Dabei ist es vorteilhaft, wenn die Mittel zum Schwenken der Halterung in der Endstellung einen Freilauf umfassen. So wird der Schwenkvorgang der Halterung auf die Überführung des Uprights von der Parkposition in die Arbeitsposition beschränkt. Ein weiters Schwenken der Räder bei geringen Auslenkungen des Oberkörpers findet dann nicht statt, so dass der Fahrkomfort nicht beeinträchtigt wird.The ease of use is increased by the fact that the movement, which performs the upper body when erecting in the parking position, is used to pivot the wheels in the rear position. In a Upright in which the tilting joint is formed by a gabelfömiges component, wherein the fork ends form the pivot axis (X) of the tilting joint and the fork web is held on the upper body, this is possible in that arranged on the tilting joint means for causing the pivoting Holder include at least one arranged on a fork end toothed segment. The means in the region of the holder can then comprise an axle carrier and an adjusting wheel acting on the holder. The wheel can be locked both in the upright position of the upper body and in an end position in the pivoted position of the upper body. It is advantageous if the means for pivoting the holder in the end position include a freewheel. Thus, the pivoting of the bracket on the transfer of the upright from the parking position in the Working position limited. A further pivoting of the wheels at low deflections of the upper body then does not take place, so that the ride comfort is not affected.

Der in den Figuren 1 bis 6 in verschiedenen Ansichten gezeigte Upright-Staubsauger, im Folgenden kurz als Upright 1 bezeichnet, besteht im Wesentlichen aus einer Bodeneinheit 2, einem Oberkörper 3 und einem dazwischen angeordneten Gelenk, welches an späterer Stelle beschrieben ist.The in the FIGS. 1 to 6 Upright vacuum cleaner shown in various views, hereinafter referred to as Upright 1, consists essentially of a bottom unit 2, an upper body 3 and a joint arranged therebetween, which will be described later.

Der Upright 1 kann aus einer aufrechten Parkposition (siehe Figuren 1 bis 3), in der er verrastbar ist und dann frei steht, nach Lösen der Verrastung (siehe Figur 7) in eine gekippte (Figuren 4 und 5) und sogar in eine vollständig gestreckte Arbeitsposition (Figur 6) gebracht werden. Dazu sind Bodeneinheit 2 und Oberkörper 3 um eine im Gebrauchszustand horizontale Achse X (siehe Figur 5) zueinander verschwenkbar gelagert. Das Gelenk, welches die Schwenkbewegung ermöglicht, wird im Folgenden als Kippgelenk bezeichnet. Außerdem kann der Upright in der gekippten Arbeitsposition, wie auch in Figur 5 dargestellt, um eine Achse Y gedreht werden. Durch Drehen des Oberkörpers 3 mittels des Geräte-Handgriffs 4 um diese Achse und gleichzeitiges Schieben oder Ziehen des Uprights kann der Benutzer die Bodeneinheit 2 um Kurven steuern. Das entsprechende Gelenk wird im weiteren Text als Drehgelenk bezeichnet.The Upright 1 can from an upright parking position (see FIGS. 1 to 3 ), in which he is latched and then stands free, after releasing the locking (see FIG. 7 ) into a tilted ( FIGS. 4 and 5 ) and even in a fully stretched working position ( FIG. 6 ) to be brought. For this purpose, ground unit 2 and upper body 3 are a horizontal axis X in use (see FIG FIG. 5 ) mounted to each other pivotally. The joint, which allows the pivoting movement, is referred to below as a tilting joint. In addition, the upright in the tilted working position, as well as in FIG. 5 shown rotated about an axis Y. By rotating the upper body 3 by means of the appliance handle 4 about this axis and simultaneously pushing or pulling the upright, the user can control the floor unit 2 around curves. The corresponding joint is referred to in the text as a hinge.

Die Bodeneinheit 2, in Figur 7 in Explosionsdarstellung gezeigt, umfasst ein Gehäuse, welches durch einen Gehäuseeinsatz 5, ein hinteres Gehäuseunterteil 6, ein vorderes Gehäuseunterteil 7, ein Stoßband 8 und ein Deckelteil 9 gebildet wird. Der Gehäuseeinsatz 5 fungiert als Träger für eine Reihe elektrischer und mechanischer Bauteile, auch die vorgenannten Gehäuseteile sind an ihm befestigt. Er bildet mit dem hinteren Gehäuseunterteil 6 unter Zwischenlage einer Motorraumdichtung 10 einen Raum zur Aufnahme eines Motorgebläses 11, welches den zum Saugbetrieb notwendigen Unterdruck erzeugt. Auf der Saugseite ist um den Gebläseeinlass 12 herum ein Dichtring 13 angeordnet, der sich ebenfalls an den beiden vorgenannten Gehäuseteilen 5 und 6 abstützt. Auf der gegenüberliegenden Seite sind Gummipuffer 14 eingelegt. Zur Tiefenreinigung von Teppichen ragt in den Saugmund 15, einer Öffnung im vorderen Gehäuseunterteil 7 und dem daran befestigten Bodenblech 16, eine Bürstwalze 17, welche an zwei seitlichen Schwingen 18 und 19 federnd gelagert ist und mittels eines Bürstenmotors 20 über einen Riemen 21 angetrieben wird. Die Teile 22 und 23 stellen eine zweiteilige Riemen-Abdeckung dar. Der Bürstenmotor 20 ist ebenfalls am Gehäuseeinsatz 5 befestigt, die Schwingen 18 und 19 sind dort schwenkbar gelagert. Die beiden Gehäuseunterteile 6 und 7 tragen das Fahrwerk des Uprights, welches aus vorderen Laufrollen 24 und 25 und Hinterrädern 26 und 27 gebildet wird. Die Hinterräder 26 und 27 sind zu Stabilisierung mittels einer Achse 28 verbunden und über je eine Radmechanik 29 bzw. 30 in ihrer Lage verstellbar. Zur Beleuchtung des Fahrwegs ist am Gehäuseeinsatz 5 eine Platine 31 mit LED's 32 befestigt, die zur Vorderseite durch eine Sichtscheibe 33 abgedeckt ist. Die Sichtscheibe 33 wird in einer Ausnehmung 34 im Stoßband 8 gehalten.The ground unit 2, in FIG. 7 shown in exploded view, comprises a housing, which is formed by a housing insert 5, a rear housing lower part 6, a front housing lower part 7, a bumper strip 8 and a cover part 9. The housing insert 5 acts as a carrier for a number of electrical and mechanical components, and the aforementioned housing parts are attached to it. It forms with the rear housing lower part 6 with the interposition of an engine compartment seal 10, a space for receiving an engine blower 11, which generates the vacuum necessary for suction operation. On the suction side, a sealing ring 13 is arranged around the fan inlet 12, which is also supported on the two aforementioned housing parts 5 and 6. On the opposite side rubber buffer 14 are inserted. For deep cleaning of carpets protrudes into the suction port 15, an opening in the front housing lower part 7 and the base plate 16 attached thereto, a brushing roller 17 which is resiliently mounted on two lateral wings 18 and 19 and driven by a brush motor 20 via a belt 21. The parts 22 and 23 represent a two-piece belt cover. The brush motor 20 is also secured to the housing insert 5, the rockers 18 and 19 are pivotally mounted there. The two housing bases 6 and 7 carry the chassis of the upright, which is formed of front wheels 24 and 25 and rear wheels 26 and 27. The rear wheels 26 and 27 are connected to stabilize by means of an axle 28 and adjustable via a respective wheel mechanism 29 and 30 in their position. To illuminate the driveway on the housing insert 5, a board 31 is attached to LED's 32, which is covered to the front by a lens 33. The viewing window 33 is held in a recess 34 in the bumper 8.

Die vom Motorgebläse 11 erzeugte Luft wird über eine Öffnung 35 im Gehäuseeinsatz 5 und eine korrespondierende Öffnung 36 im Deckelteil 9 in die Umgebung geblasen. In die Öffnung 36 ist ein Filterrahmen 37 eingesetzt, welcher einen nicht dargestellten Abluftfilter zur Reinigung der ausgeblasenen Luft von Feinstpartikeln aufnimmt. Der Filterrahmen 37 wird durch eine Gitteraufnahme 38 und ein Gitter 39 im Deckelteil 9 verkleidet und ist von dort auswechselbar.The air generated by the engine fan 11 is blown through an opening 35 in the housing insert 5 and a corresponding opening 36 in the cover part 9 in the environment. In the opening 36, a filter frame 37 is used, which receives an exhaust filter, not shown, for cleaning the air blown out of ultrafine particles. The filter frame 37 is covered by a grid receptacle 38 and a grid 39 in the lid part 9 and is interchangeable from there.

Sowohl das Kippgelenk als auch das Drehgelenk zwischen der Bodeneinheit 2 und dem an späterer Stelle beschriebenen Oberkörper 3 werden durch ein starres, gabelförmiges Kanalbauteil gebildet. Dieses Bauteil beinhaltet außerdem Teile der Luftführung vom Saugmund 15 zum Oberkörper 3 und die Luftführung vom Oberkörper 3 zur Ausblasöffnung (Öffnungen 35 und 36). Das Bauteil wird im Folgenden als Gabel 40 bezeichnet und ist in Figuren 9 und 9a in der Einbaulage dargestellt. Es besteht aus zwei Kunststoffteilen, einer Oberschale 41 und einer Unterschale 42, die durch Schweißen miteinander verbunden sind. Zur Realisierung des Kippgelenks sind die beiden Enden 43 (rechts) und 44 (links) der Gabel 40 schwenkbar in hierfür vorgesehenen Ausnehmungen 45 und 46 gelagert, zur Vermeidung von Abrieb sind sie jeweils von metallischen Lagerbuchsen 47 und 48 umgeben. Das in Fahrtrichtung linke Gabelende 44 ist als hohl ausgeführt und über eine Dichtung 49 mit dem Gebläseeinlass 12 gekoppelt. An das in Fahrtrichtung rechte Gabelende 43 ist ein Lagerzapfen 50 angeformt. Es besitzt außerdem eine Öffnung 51, welche über einen elastischen Schlauch 52 mit dem Saugmund 15 verbunden ist. Um beim Kippen des Oberkörpers 3 den Einblick ins Innere der Bodeneinheit 2 zu verwehren, ist der Verbindungsbereich der beiden Gabelenden 43 und 44, im Folgenden als Gabelsteg 53 bezeichnet, von einer vorderen Abdeckung 54 und einer hinteren Abdeckung 55 an der Bodeneinheit 2 umgeben, welche die Schwenkbewegung der Gabel 40 mit ausführen. Der Zwischenraum zwischen der vorderen bzw. hinteren Abdeckung und dem Gehäuseeinsatz 5 wird durch Blenden 56 und 57 überbrückt. An dem linken Gabelende 44 ist der erste 58 von zwei Kabelkanälen 58 und 59 befestigt. Des Weiteren tragen die Gabelenden 43 und 44 Zahnsegmente 60 und 61, die mit den Radmechaniken 29 und 30 zusammenwirken. Am Gabelsteg 53 ist ein Verkleidungsdeckel 62 für ein nicht dargestelltes Verbindungskabel befestigt. Um den Upright in der Parkposition (Figuren 1 bis 3) verrasten zu können, ist am Gehäuseeinsatz 5 ein Tritthebel 63 gelagert, der in dieser Position in das linke Gabelende 44 eingreift und damit die Schwenkbewegung der Gabel 40 verhindert. Durch Herunterdrücken des Hebels 63 kann die Verriegelungsposition gelöst werden. In der Parkposition wird außerdem durch zwei federgelagerte Bolzen 64 und 65 eine Drehbewegung verhindert. Die Luftleitungen, die durch die Gabelenden 43 und 44 gebildet werden, sind im Bereich des Gabelstegs 53 zu einem ersten Abschnitt 66 einer Koaxialleitung vereinigt.Both the tilting joint and the pivot joint between the base unit 2 and the upper body 3 described later are formed by a rigid, fork-shaped channel component. This component also includes parts of the air duct from the suction port 15 to the upper body 3 and the air guide from the upper body 3 to the exhaust opening (openings 35 and 36). The component is referred to below as fork 40 and is in FIGS. 9 and 9a shown in the installation position. It consists of two plastic parts, an upper shell 41 and a lower shell 42, which are interconnected by welding. To realize the tilting joint, the two ends 43 (right) and 44 (left) of the fork 40 are pivotally mounted in recesses 45 and 46 provided for this purpose, to avoid abrasion, they are respectively surrounded by metallic bushings 47 and 48. The left in the direction of travel fork 44 is designed as hollow and a seal 49 with the blower inlet 12th coupled. At the right in the direction of travel fork 43 a bearing pin 50 is formed. It also has an opening 51 which is connected via an elastic tube 52 to the suction port 15. In order to prevent the inside of the bottom unit 2 when tilting the upper body 3, the connecting region of the two fork ends 43 and 44, hereinafter referred to as fork web 53, surrounded by a front cover 54 and a rear cover 55 on the bottom unit 2, which perform the pivoting movement of the fork 40 with. The space between the front and rear cover and the housing insert 5 is bridged by aperture 56 and 57. At the left fork end 44, the first 58 of two cable channels 58 and 59 is attached. Furthermore, the fork ends 43 and 44 carry toothed segments 60 and 61 which cooperate with the wheel mechanisms 29 and 30. At the fork web 53, a trim cover 62 is attached to a connection cable, not shown. To the upright in the parking position ( FIGS. 1 to 3 ), a stepping lever 63 is mounted on the housing insert 5, which engages in this position in the left fork end 44 and thus prevents the pivoting movement of the fork 40. By depressing the lever 63, the locking position can be released. In the parking position is also prevented by two spring-loaded bolts 64 and 65 a rotational movement. The air ducts, which are formed by the fork ends 43 and 44, are combined in the region of the fork web 53 to a first portion 66 of a coaxial line.

Figur 8 zeigt den Oberkörper 3, ebenfalls in Explosionsdarstellung. Tragendes Bauteil des Oberkörpers 3 ist eine Rückwand 67. Sie bildet den hinteren Bereich des Staubraums 68, der wiederum einen in der Zeichnung nicht dargestellten Filterbeutel aufnimmt. Der Rand des Staubraums 68 ist von einer Dichtung 69 umgeben, seitlich ist eine Abdeckleiste 70 für nicht dargestellte Kabel befestigt. Im unteren Bereich ist an der Rückwand 67 ein Scharnierlager 71 befestigt. Der Staubraum 68 wird nach vorn durch ein Gehäuseoberteil 72 abgeschlossen, welches über Scharniere 73 und Drehfedern 74 schwenkbar am Scharnierlager 71 angelenkt ist. Das Oberteil 72 trägt einen Verschluss 75, eine Staubbeutel-Aufnahme 76 und eine Filterwechsel-Anzeige 77. Es verkleidet außerdem das Scharnierlager 71. Im oberen Bereich trägt die Rückwand 67 die Elektronik 78 des Uprights, welche komplett auf einer Aufnahme 79 angeordnet ist und als vorgeprüftes Komponenten-Bauteil montierbar ist. An der Aufnahme ist über eine Drehfeder 80 ein Hebel 81 zur Abschaltung des Bürstenmotors 20 angeordnet. Außerdem stellt sie die Halterung für das Griffrohr 82 mit dem Geräte-Handgriff 4. Die Elektronik 78 wird durch eine Kappe 84 verkleidet, welche auch zur Befestigung für verschiedene Bedienelemente und Anzeigeelemente und deren Zubehör (Sichtscheibe 85, Drehknopf 86) dient. FIG. 8 shows the upper body 3, also in exploded view. Carrying component of the upper body 3 is a rear wall 67. It forms the rear portion of the dust chamber 68, which in turn receives a filter bag, not shown in the drawing. The edge of the dust chamber 68 is surrounded by a seal 69, the side of a cover strip 70 is fixed for cables, not shown. In the lower area a hinge bearing 71 is attached to the rear wall 67. The dust chamber 68 is closed at the front by an upper housing part 72, which is articulated via hinges 73 and torsion springs 74 pivotally mounted on the hinge bearing 71. The upper part 72 carries a closure 75, a dust bag receptacle 76 and a filter change indicator 77. It also disguises the hinge bearing 71. In the upper part, the rear wall 67 carries the electronics 78 of Uprights, which is completely arranged on a receptacle 79 and as pre-tested component component is mounted. On the recording, a lever 81 for switching off the brush motor 20 is arranged via a torsion spring 80. In addition, it provides the holder for the handle tube 82 with the device handle 4. The electronics 78 is covered by a cap 84, which also serves for attachment to various controls and display elements and their accessories (lens 85, knob 86).

Eine aufwändige Luftführung sorgt dafür, dass schmutzbeladene Luft wahlweise über den Saugmund in der Bodeneinheit als auch über ein Teleskoprohr mit eventuell angeschlossenen Saugvorsätzen wie Fugendüse, Möbelpinsel, Polsterdüse etc. eingesaugt werden kann. Hierzu wird die Saugluft vom Saugmund 15 über den elastischen Schlauch 52 und das rechte Gabelende 43 durch das Innenrohr des ersten Abschnitts 66 der Koaxialleitung im Gabelsteg 53 in das Innenrohr eines zweiten Abschnitts 87 der Koaxialleitung geleitet. Dieser Abschnitt 87 wird in der Rückwand 67 fortgesetzt und dort auch wieder in zwei separate Leitungen getrennt. Der weitere Luftweg führt durch ein Saugkanalstück 88 in einen Krümmer 89. In den Krümmer 89 ist lose - und deshalb herausnehmbar - ein Teleskoprohr 90 gesteckt, welches über einen Rohrgriff 91 in einen flexiblen Saugschlauch 92 übergeht. Der Saugschlauch 92 wird in einer dafür vorgesehenen Aufnahme 93 gehalten, wie auch in Figur 3 erkennbar ist. Über einen Schwenkbogen 94 gelangt die Luft in einen Kanal, der sich über die gesamte Länge der Rückwand 67 erstreckt. Der Kanal wird aus der Rückwand 67 selbst und einem aufgesetzten Luftkanalstück 95 gebildet. Anschließend führt ein bogenförmiger Stutzen 96, der aus der Rückwand 67 und zum Teil aus der Elektronik-Aufnahme 79 besteht, die schmutzbeladene Saugluft in den Bereich der Staubbeutel-Aufnahme 76 und dort in einen nicht dargestellten Staubbeutel. Nachdem die Saugluft den Staubbeutel im Staubraum durchströmt hat und dort vom Staub gereinigt worden ist, gelangt sie durch ein Motorschutzfilter - in der Figur ist nur der Rahmen 97 zur Halterung des Filters dargestellt - in den Außenring des zweiten Abschnitts 87 der Koaxialleitung und von dort durch den ersten Abschnitt 66 über das linke Gabelende 44 zum Motorgebläse 11.An elaborate air duct ensures that dirt-laden air can either be sucked in via the suction mouth in the floor unit or via a telescopic tube with possibly connected suction attachments such as crevice nozzle, furniture brush, upholstery nozzle, etc. For this the suction air is passed from the suction port 15 via the elastic tube 52 and the right fork end 43 through the inner tube of the first portion 66 of the coaxial line in the fork web 53 in the inner tube of a second section 87 of the coaxial line. This section 87 is continued in the rear wall 67 and there again separated into two separate lines. The further air path leads through a Saugkanalstück 88 in a manifold 89. In the manifold 89 is loosely - and therefore removable - a telescopic tube 90 inserted, which passes via a pipe handle 91 in a flexible suction hose 92. The suction hose 92 is held in a receptacle 93 provided therefor, as well as in FIG. 3 is recognizable. Via a pivoting arc 94, the air enters a channel which extends over the entire length of the rear wall 67. The channel is formed from the rear wall 67 itself and an attached air duct piece 95. Subsequently, an arcuate neck 96, which consists of the rear wall 67 and partly of the electronic receptacle 79, the dirt-laden suction air in the area of the dust bag receptacle 76 and there in a dust bag, not shown. After the suction air has flowed through the dust bag in the dust chamber and has been cleaned of dust, it passes through a motor protection filter - in the figure, only the frame 97 is shown for holding the filter - in the outer ring of the second portion 87 of the coaxial line and from there the first section 66 via the left fork 44 to the engine fan 11th

In der Figur 8 sind außerdem im unteren Bereich die Bauteile dargestellt, die zur Befestigung und drehbaren Lagerung des Oberkörpers 3 an der Gabel 40 dienen. Der erste Abschnitt 66 der Koaxialleitung wird von einem eingespritzten Metallring 98 umgeben, welcher den Außendurchmesser dieses Abschnitts 66 überragt und welcher in zwei Lagerschalen 99 bzw. 100 eingefasst ist. Die Lagerschalen 99 und 100 sind mit dem Oberkörper 3 verbunden. Somit bilden Metallring 98 und Lagerschalen 99 und 100 das Drehgelenk des Uprights 1. Bei der Verbindung von Oberkörper 3 und Gabel 40 werden die beiden Abschnitte 66 und 87 der Koaxialleitung unter Zwischenlage einer Dichtung 101 zusammengefügt.In the FIG. 8 are also shown in the lower part of the components that serve for attachment and rotatable mounting of the upper body 3 to the fork 40. The first section 66 of the coaxial line is surrounded by an injected metal ring 98, which projects beyond the outer diameter of this section 66 and which is enclosed in two bearing shells 99 and 100, respectively. The bearing shells 99 and 100 are connected to the upper body 3. Thus, metal ring 98 and bearing shells 99 and 100 form the pivot of Uprights 1. In the connection of the upper body 3 and fork 40, the two sections 66 and 87 of the coaxial line with the interposition of a seal 101 are assembled.

In Figur 9 ist das Motorgebläse 11 erkennbar, welches in das hintere Gehäuseunterteil 6 eingelegt ist und vom Gehäuseeinsatz 5 abgedeckt wird. Wie bereits weiter oben beschrieben, ermöglicht die Motorraumdichtung 10 aufgrund ihres H-Profils eine luftdichte Verbindung dieser beiden Teile. Auf der Saugseite ist um den Gebläseeinlass 12 herum der Dichtring 13 angeordnet, der sich ebenfalls an den beiden vorgenannten Gehäuseteilen 5 und 6 abstützt. Die vergrößerte Darstellung in Figur 9a zeigt, dass der Gehäuseeinsatz 5 im Bereich des Gebläseeinlasses 12 zu einem hülsenförmigen Ansatz 501 erweitert ist. Hierdurch werden in diesem Bereich Stoßstellen der beiden Gehäuseteile vermieden. Das in Fahrtrichtung (aus der Zeichnungsebene heraus) rechte Gabelende 43 (in der Figur 9 links dargestellt) ist, wie weiter oben beschrieben, als Lagerzapfen ausgebildet und von einer metallischen Lagerbuchse 47 eingefasst. Es wird von einem geschlossenen Lagersitz aufgenommen, der beim Zusammensetzen des hinteren Gehäuseunterteils 6 durch die Ausnehmung 45 und ein entsprechendes Pendant 103 des Gehäuseeinsatzes 5 entsteht. In der Figur 9 ist ebenfalls die Öffnung 51 erkennbar, in welche das zum Saugmund 15 führende Schlauchstück (s. Figur 7) gesteckt ist. Das in Fahrtrichtung linke Gabelende 44 (in der Figur 9 rechts dargestellt) bildet sowohl die Luftführung vom Oberkörper zur Saugseite des Gebläses 11 (Gebläseeinlass 12) als auch den Drehpunkt des Kippgelenks. Es ist deshalb hohl ausgeführt und am Ende mit einer Dichtung 49 versehen. Die Dichtung 49 liegt am Ansatz 501 an und sorgt für einen luftdichten Übergang zwischen Gebläse 11 und Gabelende 44. Hierdurch kann eine hohe Saugkraft erzielt werden. Die Lagerung erfolgt wie beim rechten Gabelende durch eine Lagerbuchse 48, die von einem Lagersitz (Ausnehmungen 46 und 104) aufgenommen wird. Die Schwenkachse X erstreckt sich in der Symmetrieachse des Motorgebläses 11, sie ist als gestrichelte Linie 102 dargestellt.In FIG. 9 is the engine fan 11 recognizable, which is inserted into the rear housing lower part 6 and is covered by the housing insert 5. As already described above, allows the engine compartment seal 10 due to their H-profile an airtight connection of these two parts. On the suction side of the blower inlet 12 around the sealing ring 13 is arranged, which is also supported on the two aforementioned housing parts 5 and 6. The enlarged view in FIG. 9a shows that the housing insert 5 is expanded in the region of the fan inlet 12 into a sleeve-shaped projection 501. As a result, joints of the two housing parts are avoided in this area. The right in the direction of travel (out of the plane) fork end 43 (in the FIG. 9 shown on the left), as described above, designed as a journal and bordered by a metallic bushing 47. It is taken up by a closed bearing seat, which at the Assembly of the rear housing lower part 6 by the recess 45 and a corresponding counterpart 103 of the housing insert 5 is formed. In the FIG. 9 is also the opening 51 recognizable, in which the leading to the suction mouth 15 hose piece (s. FIG. 7 ) is plugged. The left in the direction of travel fork 44 (in the FIG. 9 shown on the right) forms both the air flow from the upper body to the suction side of the blower 11 (fan inlet 12) and the pivot point of the tilting joint. It is therefore made hollow and provided at the end with a seal 49. The seal 49 bears against the projection 501 and ensures an airtight transition between the blower 11 and the fork end 44. In this way, a high suction force can be achieved. The storage takes place as in the right fork end by a bearing bush 48 which is received by a bearing seat (recesses 46 and 104). The pivot axis X extends in the axis of symmetry of the engine blower 11, it is shown as a dashed line 102.

Durch einen Vergleich der Figuren 2 und 4 ist bereits erkennbar, dass die Hinterräder 26 und 27 in Abhängigkeit vom Winkel des Oberkörpers 3 unterschiedliche Stellungen einnehmen. In der Parkposition mit senkrechtem Oberkörper 3 (Figur 1) befinden sich die Räder 26 und 27 in einer hinteren Stellung, hierdurch wird die Standfläche so weit vergrößert, dass sich die senkrechte Projektion des Schwerpunkts auf den Boden innerhalb der Standfläche befindet. Somit steht der Upright 1 selbständig. In der Arbeitsposition mit gekipptem Oberkörper (Figur 4) wandern die Hinterräder 26 und 27 weiter nach vorn, dies verbessert die Manövrierfähigkeit des Uprights 1 insbesondere bei Kurvenfahrten. Um zu gewährleisten, dass das Schwenken des Oberkörpers 3 um die Kippachse X eine automatische Verlagerung der Hinterräder 26, 27 in die jeweils richtige Stellung verursacht, sind die Hinterräder 26, 27 jeweils mit einer Radmechanik 29 bzw. 30 ausgestattet, die nachfolgend unter Bezugnahme auf die Figuren 10 bis 16 beschriebenen wird:By comparing the Figures 2 and 4 It can already be seen that the rear wheels 26 and 27 occupy different positions depending on the angle of the upper body 3. In the parking position with vertical upper body 3 ( FIG. 1 ) are the wheels 26 and 27 in a rear position, thereby the floor space is increased so that the vertical projection of the center of gravity is located on the ground within the floor space. Thus, the Upright 1 is independent. In the working position with tilted upper body ( FIG. 4 ), the rear wheels 26 and 27 continue to move forward, this improves the maneuverability of Uprights 1 especially when cornering. In order to ensure that the pivoting of the upper body 3 about the tilting axis X causes an automatic displacement of the rear wheels 26, 27 in the respectively correct position, the rear wheels 26, 27 are each equipped with a wheel mechanism 29 and 30, respectively, with reference to the FIGS. 10 to 16 is described:

Figur 10 zeigt eine Radmechanik 30 in Explosionsdarstellung. Sie besteht aus einer gabelförmigen Halterung 300, einer Drehfeder 301, einem Achsträger 302, zwei Achsen 303 und 304 und einem Stellrad 305. Die Halterung 300 nimmt das Hinterrad 27 auf, welches über die durchgängige Achse 28 mit dem anderen Hinterrad 26 gekoppelt ist. Sie bildet den schwenkbaren Bestandteil der Mechanik 30, mit welcher die Positionsveränderung erreicht wird. Der Achsträger 302 stellt den ortsfesten Bestandteil der Mechanik 30 dar und ist am hinteren Gehäuse-Unterteil 6 befestigt. Er besitzt hierzu zwei Laschen 306 und 307, die am Unterteil 6 verschraubt werden, die Schrauben und die korrespondierenden Bohrungen im Gehäuse-Unterteil 6 sind in den Zeichnungen nicht dargestellt. Der Achsträger 302 nimmt in entsprechenden Bohrungen 308 und 309 die beiden Achsen 303 und 304 auf, von denen die untere 303 zur schwenkbaren Lagerung der Halterung 300 dient und die obere 304 zur drehbaren Lagerung des Stellrads 305. Das Stellrad 305 besteht, wie in Figur 11 erkennbar ist, aus einem Zahnkranz 310, einer Mitnehmerscheibe 311 mit einer Vertiefung 312 und einem neben der Vertiefung 312 angeordneten Initialnocken 313. Figur 12 zeigt die Halterung 300 in einer vergrößerten Einzeldarstellung. Dort ist erkennbar, dass im Bereich der Bohrung 314 für die Achse 303 zunächst ein Mitnehmernocken 315 und daneben ein nach beiden Seiten ausgedehnter Initialhebel 316 angeformt sind. Der Mitnehmernocken 315 liegt in einer Drehebene mit der Vertiefung 312, der Initialhebel 316 liegt in der Ebene des lnitialnockens 313. Die Drehfeder 301 ist um die Verlängerung der unteren Achse 303 gewickelt, die aus der Bohrung 314 der Halterung 300 ragt. Das gerade Ende 319 stützt sich in einer Nut 321 an der Halterung 300 ab, das gekrümmte Ende 320 an der Verlängerung der oberen Achse 304 durch das Stellrad 305. FIG. 10 shows a wheel mechanism 30 in an exploded view. It consists of a fork-shaped holder 300, a torsion spring 301, an axle carrier 302, two axes 303 and 304 and a thumbwheel 305. The holder 300 receives the rear wheel 27, which is coupled via the continuous axis 28 with the other rear wheel 26. It forms the pivotable component of the mechanism 30, with which the position change is achieved. The axle carrier 302 represents the stationary component of the mechanism 30 and is attached to the rear housing lower part 6. He has this two tabs 306 and 307, which are bolted to the lower part 6, the screws and the corresponding holes in the housing base 6 are not shown in the drawings. The axle carrier 302 receives in corresponding bores 308 and 309 the two axes 303 and 304, of which the lower 303 serves for the pivotable mounting of the holder 300 and the upper 304 for the rotatable mounting of the setting wheel 305. The thumbwheel 305 consists, as in FIG. 11 can be seen from a ring gear 310, a drive plate 311 with a recess 312 and a in addition to the recess 312 arranged initial cam 313th FIG. 12 shows the holder 300 in an enlarged detail view. There, it can be seen that, in the region of the bore 314 for the axle 303, initially a driver cam 315 and next to it an initial lever 316 extended to both sides are formed. The cam lobe 315 is in a plane of rotation with the recess 312, the initial lever 316 is in the plane of the initial cam 313. The torsion spring 301 is wound around the extension of the lower axis 303, which protrudes from the bore 314 of the holder 300. The straight end 319 is supported in a groove 321 on the holder 300, the curved end 320 on the extension of the upper axis 304 by the thumbwheel 305th

In Figur 13 ist erkennbar, dass das Zahnsegment 61 am Gabelende 44 mit dem Zahnkranz 310 des Stellrads 305 kämmt. Die Zahnlücke 322 (s. Figur 11) dient als Positionierhilfe beim Montagevorgang, sie wird in einen modifizierten Zahn 323 des Zahnsegments 61 eingesetzt.In FIG. 13 It can be seen that the toothed segment 61 meshes with the toothed rim 310 of the setting wheel 305 at the fork end 44. The tooth gap 322 (s. FIG. 11 ) serves as a positioning aid in the assembly process, it is inserted into a modified tooth 323 of the toothed segment 61.

Anhand der Figuren 14 bis 16 wird nun der Bewegungsablauf in der Radmechanik 30 beim Schwenken des Oberkörpers 3 aus Parkposition (Figur 14) während des Schwenkens (Figur 15) in die gekippte Arbeitsposition (Figur 16) erläutert. In den Figuren ist jeweils die Draufsicht (a) von oben auf das linke Gabelende 44 und die Radmechanik 30 und drei Schnitte in verschiedenen Stellrad-Ebenen, nämlich durch den Zahnkranz 310 (b), die Mitnehmerscheibe 311 (c) und den Initialnocken 313 (d) gezeigt. In der Parkposition (Figuren 14a bis d) befindet sich das Gabelende 44 in der Ein-Uhr-Stellung, das Zahnsegment 61 steht mit seinem linken Rand in Eingriff mit dem Zahnkranz 310 des Stellrads 305 (Figur 14b). Die Vertiefung 312 in der Mitnehmerscheibe 311 ist am Mitnehmernocken 315 vorbeigelaufen, so dass der Rand der Scheibe 311 den Nocken 315 nach unten drückt und in dieser Position hält (Figur 14c). Das Rad 27 ist hierdurch in der hinteren Position verriegelt, selbst ein weiteres Drehen des Stellrads 305 würde lediglich den Rand frei auf dem Mitnehmernocken 315 laufen lassen. Die Feder 301 ist in dieser Position gespannt, der Initialnocken 313 liegt vor dem rechten Arm 318 des Initialhebels 316 und damit außerhalb seines Wirkbereichs (Figur 14 d). Wird nun der Oberkörper 3 nach hinten gekippt (Figuren 15a bis d), drehen sich das Gabelende 44 und damit das Zahnsegment 61 im Uhrzeigersinn (Figur 15 b). Der Zahnkranz 310 wird dann vom Zahnsegment 61 gegen den Uhrzeigersinn gedreht. Dabei drückt der Initialnocken 313 gegen den rechten Arm 318 des Initialhebels 316 (Figur 15d) und verursacht ein geringes Schwenken der Halterung 300 im Uhrzeigersinn. Diese Drehbewegung um wenige Winkelgrade reicht aus, um den Mitnehmernocken 315 in die Vertiefung 312 der Mitnehmerscheibe 311 zu drücken (Figur 15c). Beim weiteren Schwenken des Gabelendes 44 nimmt dann die Vertiefung 312 den Mitnehmernocken 311 mit und schwenkt die Halterung 300 samt Hinterrad 27 nach vorn, d. h. im Uhrzeigersinn. Die Drehfeder 301 entspannt sich und unterstützt diese Bewegung. Durch weiteres Schwenken gelangt der Oberkörper 3 in die Arbeitsposition, die Figuren 16a bis d zeigen das Gabelende 44 bei maximal geschwenktem, d. h. liegendem Oberkörper 3 in der Vier-Uhr-Stellung. Dabei ist der rechte Rand des Zahnsegments 61 mit dem Zahnkranz 310 im Eingriff (Figur 16b). Das Stellrad 305 hat sich wieder so weit gedreht, dass der Mitnehmernocken 315 aus der Vertiefung 312 herausgeglitten ist und durch den Rand der Mitnehmerscheibe 311 nach unten gedrückt wird. Somit ist das Hinterrad 27 auch in dieser Position verriegelt und das Stellrad 305 läuft frei. Die Feder 301 ist entspannt und der Initialnocken 313 steht nicht im Eingriff mit dem Initialhebel 316 (Figur 16d). Wenn nun das Gabelende so weit zurück gegen den Uhrzeigersinn geschwenkt wird, dass der Initialnocken 313 an den linken Arm 317 des Initialhebels 316 stößt, wird wieder ein Eingreifen des Mitnehmernockens 315 in die Vertiefung der Mitnehmerscheibe 311 und damit ein Schwenken der Halterung 300 nach hinten verursacht.Based on FIGS. 14 to 16 Now, the movement in the wheel mechanism 30 during pivoting of the upper body 3 from parking position ( FIG. 14 ) while panning ( FIG. 15 ) into the tilted working position ( FIG. 16 ) explained. In the figures, the plan view (a) from above on the left fork end 44 and the wheel mechanism 30 and three sections in different Stellrad-planes, namely by the ring gear 310 (b), the drive plate 311 (c) and the initial cam 313 ( d). In the parking position ( FIGS. 14a to d ), the forked end 44 is in the one o'clock position, the toothed segment 61 is in engagement with the toothed rim 310 of the setting wheel 305 (FIG. FIG. 14b ). The recess 312 in the drive plate 311 has passed the drive cam 315, so that the edge of the disc 311 pushes the cam 315 downwards and holds in this position ( FIG. 14c ). The wheel 27 is thereby locked in the rear position, even further rotation of the thumb wheel 305 would only allow the rim to run freely on the cam cam 315. The spring 301 is stretched in this position, the initial cam 313 is in front of the right arm 318 of the initial lever 316 and thus outside its effective range ( FIG. 14 d) , If now the upper body 3 is tilted backwards ( FIGS. 15a to d) , the fork end 44 and thus the toothed segment 61 rotate clockwise ( FIG. 15 b) , The ring gear 310 is then rotated by the toothed segment 61 in the counterclockwise direction. In this case, the initial cam 313 presses against the right arm 318 of the initial lever 316 (FIG. FIG. 15d ) and causes a slight pivoting of the holder 300 in a clockwise direction. This rotational movement by a few angular degrees is sufficient to press the driving cam 315 into the recess 312 of the drive plate 311 ( FIG. 15c ). Upon further pivoting of the fork end 44 then takes the recess 312 the driving cam 311 and pivots the holder 300 together with the rear wheel 27 forward, ie clockwise. The torsion spring 301 relaxes and supports this movement. By further pivoting the upper body 3 reaches the working position, the FIGS. 16a to d show the fork end 44 at maximum pivoted, ie lying upper body 3 in the Four o'clock position. In this case, the right edge of the toothed segment 61 with the ring gear 310 is engaged ( FIG. 16b ). The thumbwheel 305 has again turned so far that the driver cam 315 is slid out of the recess 312 and is pressed by the edge of the drive plate 311 down. Thus, the rear wheel 27 is locked in this position and the thumbwheel 305 runs free. The spring 301 is relaxed and the initial cam 313 is not engaged with the initial lever 316 (FIG. FIG. 16d ). Now, if the fork end is pivoted so far back in the counterclockwise direction that the initial cam 313 abuts the left arm 317 of the initial lever 316, engagement of the Mitnehmerockens 315 is again caused in the recess of the drive plate 311 and thus pivoting of the holder 300 to the rear ,

Aus dem Vergleich der Figuren 14 und 16 ist auch erkennbar, dass die Hinterräder 26 und 27 in der Parkposition weiter nach unten gedrückt werden. Hierdurch wird die Bodeneinheit 2 im hinteren Bereich so weit angehoben, dass sie im vorderen Bereich nicht mehr auf den Laufrollen 24 und 25 steht, sondern auf eigens hierfür vorgesehene Gummistützen 324 und 325, die außerdem noch zur Umrahmung von Nebenluftöffnungen 326 und 327 im Bodenblech 16 dienen (siehe Figur 17). Hierdurch werden die Laufrollen 24 vom Boden abgehoben und dienen nicht mehr zur Unterstützung einer möglichen Fahrbewegung der Bodeneinheit. Diese wird dann durch den Bodenkontakt der Gummistützen 324 und 325 in der Parkposition gebremst.From the comparison of Figures 14 and 16 It can also be seen that the rear wheels 26 and 27 are pressed further down in the parking position. As a result, the bottom unit 2 is raised so far in the rear area that it no longer stands on the rollers 24 and 25 in the front area, but on specially provided rubber supports 324 and 325, which also still for framing of secondary air openings 326 and 327 in the floor panel sixteenth serve (see FIG. 17 ). As a result, the rollers 24 are lifted from the ground and no longer serve to support a possible driving movement of the ground unit. This is then braked by the ground contact of the rubber supports 324 and 325 in the park position.
