Description

Die Erfindung betrifft ein fahrbares Hochdruckreinigungsgerät mit Rädern oder Rollen zumindest an seinem hinteren Ende und mit einem Handgriff zum Verfahren des Hochdruckreinigungsgerätes, der an seinem vorderen Ende angreift. Ein derartiges berät ist aus der WO-A-92/16 313 bekannt.The invention relates to a mobile high-pressure cleaning device with wheels or rollers at least at its rear end and with a handle for moving the high-pressure cleaning device which engages at its front end. Such advice is known from WO-A-92/16 313.

Es sind insbesondere kleinere Hochdruckreinigungsgeräte bekannt, die mittels eines Handgriffs verfahren werden können. Derartige Hochdruckreinigungsgeräte haben üblicherweise nur an ihrem hinteren Ende ein Rollenpaar und werden durch den Handgriff nach Art eines zweirädrigen Karrens vom Benutzer hinter sich hergezogen. Da die Geräte relativ klein sind, sind die Handgriffe relativ zum Gerät sperrig ausgebildet, so daß sich beim Aufbewahren der Geräte unter Umständen Platzprobleme ergeben können. Es ist dazu bekannt, Handgriffe bei Hochdruckreinigungsgeräten einschiebbar auszugestalten, um zur Aufbewahrung die gesamte Baugröße herabzusetzen. Bei derartigen Geräten ist es jedoch notwendig, die Baugröße dadurch zu vergrößern, daß zusätzliche Halterungen zur Aufnahme von Zubehör vorgesehen werden.In particular, smaller high-pressure cleaning devices are known which can be moved by means of a handle. Such high-pressure cleaning devices usually only have a pair of rollers at their rear end and are pulled behind by the user in the manner of a two-wheeled cart. Since the devices are relatively small, the handles are bulky relative to the device, so that space problems may arise when storing the devices. It is known to handle in high pressure cleaning devices designed to be insertable in order to reduce the overall size for storage. In such devices, however, it is necessary to increase the size by providing additional brackets for receiving accessories.

Es ist Aufgabe der Erfindung, ein Hochdruckreinigungsgerät der gattungsgemäßen Art so auszubilden, daß einerseits eine bequeme Handhabung und ein bequemer Transport im Betrieb möglich sind und daß andererseits eine platzsparende Aufbewahrung erreichbar ist.It is an object of the invention to design a high-pressure cleaning device of the generic type in such a way that, on the one hand, convenient handling and transport are possible in operation, and on the other hand that space-saving storage can be achieved.

Diese Aufgabe wird bei einem fahrbaren Hochdruckreinigungsgerät der eingangs beschriebenen Art dadurch gelöst, daß der Handgriff um eine parallel zur Achse der Räder oder Rollen verlaufende Achse verschwenkbar am Hochdruckreinigungsgerät gelagert und derart abgewinkelt oder abgebogen ausgebildet ist, daß der sich auf dem Untergrund abstützende Handgriff zu seinem freien Ende hin schräg oder senkrecht nach oben gerichtet ist, und daß in dem nach oben gerichteten Abschnitt des Handgriffs an diesem ebenfalls nach oben gerichtete Aufnahmen für Gerätezubehör angeordnet sind.This object is achieved in a mobile high-pressure cleaning device of the type described at the outset in that the handle is mounted on the high-pressure cleaning device so as to be pivotable about an axis running parallel to the axis of the wheels or rollers, and is designed such that it is angled or bent such that the handle, which is supported on the surface, is his free end is directed obliquely or vertically upward, and that in the upward section of the handle on this also upward receptacles for device accessories are arranged.

Ein in dieser Weise schwenkbarer Handgriff ermöglicht eine platzsparende Aufbewahrung, da der Handgriff bei der Aufbewahrung eingeschwenkt werden kann. Andererseits läßt sich das Gerät auch mit einem schwenkbaren Handgriff ohne weiteres transportieren, das Gerät hängt dann gleichsam an dem Handgriff, so daß ein einwandfreier Transport gewährleistet ist. Die Handhabung des Gerätes insgesamt wird dadurch ganz erheblich verbessert, daß der Handgriff aufgrund seiner speziellen Ausgestaltung gleichzeitig zur Aufnahme von Zubehör ausgebildet ist. Um dies bei einem schwenkbaren Handgriff zu ermöglichen, ist dieser so abgebogen oder abgewinkelt, daß er sich zwischen seinem Schwenklager und dem freien Ende am Boden abstützt. Man erhält dadurch am freien Ende nach oben weisende und daher leicht zugängliche Aufnahmen für Zubehör, beispielsweise für Strahlrohre, Waschbürsten etc.A handle that can be swiveled in this way enables space-saving storage, since the handle can be swiveled in during storage. On the other hand, the device can also be easily transported with a swiveling handle, the device then hangs on the handle, so to speak, so that perfect transportation is ensured. The handling of the device as a whole is considerably improved in that the handle is due to its special design is designed to accommodate accessories. In order to make this possible with a pivotable handle, it is bent or angled in such a way that it is supported on the floor between its pivot bearing and the free end. This results in receptacles for accessories, for example for jet pipes, washing brushes, etc., which point upwards and are therefore easily accessible.

Es ist dabei vorteilhaft, wenn die Aufnahmen Einsteckhülsen für Strahlrohre sind. Dabei kann vorzugsweise zu beiden Seiten des Handgriffs je eine Einsteckhülse angeordnet sein. Günstig ist es, wenn die Einsteckhülsen durch außen an den Handgriff angeformte gebogene Lappen gebildet werden, es ist also gar nicht notwendig, die Strahlrohre allseits umgebende Köcher auszubilden.It is advantageous if the receptacles are insertion sleeves for jet pipes. In this case, an insertion sleeve can preferably be arranged on both sides of the handle. It is expedient if the insertion sleeves are formed by curved tabs formed on the outside of the handle, so it is not at all necessary to design the quiver tubes which surround the sides.

Es kann auch vorgesehen sein, daß die Aufnahmen Gleitführungen für eine Waschbürste sind. Dabei ist es vorteilhaft, wenn die Gleitführung zwischen zwei Einsteckhülsen angeordnet ist. Vorzugsweise umfaßt die Gleitführung zwei seitlich offene, parallele Nuten, in die der Rand der Borstenplatte einer Waschbürste einschiebbar ist.It can also be provided that the receptacles are sliding guides for a washing brush. It is advantageous if the sliding guide is arranged between two insertion sleeves. Preferably, the slide guide comprises two laterally open, parallel grooves into which the edge of the bristle plate of a washing brush can be inserted.

Die Handhabung wird erleichtert, wenn der Handgriff an seinem freien Ende einen quer zu seiner Längsrichtung verlaufenden Griffsteg trägt.Handling is facilitated if the handle carries at its free end a handle bar extending transversely to its longitudinal direction.

Bei einer bevorzugten Ausführungsform weist der Handgriff zwei parallel verlaufende Schenkel auf, zwischen diesen kann sich dann beispielsweise die Aufnahme für die Waschbürste befinden, während die Einsteckhülsen für Strahlrohre jeweils an der Außenseite der beiden Schenkel angeordnet sind. Ein Griffsteg am freien Ende wird dann als beide Schenkel verbindende Brücke ausgebildet.In a preferred embodiment, the handle has two parallel legs, between which, for example, the receptacle for the washing brush can be located, while the insertion sleeves for jet pipes are each arranged on the outside of the two legs. A handle bar at the free end is then designed as a bridge connecting the two legs.

Eine ganz besonders günstige Ausgestaltung ergibt sich dann, wenn die Abmessungen des Handgriffs derart an die Außenkontur des Hochdruckreinigungsgerätes angepaßt sind, daß der Handgriff mit seinem die Aufnahmen aufweisenden Teil parallel zur Oberseite des Gerätes verlaufend umgelegt werden kann. In der eingeklappten oder umgelegten Position liegen somit der dem freien Ende zugewandte Teil des Handgriffs und die daran angeordneten Aufnahmen für Zubehör parallel zur Oberseite und dicht an dieser an, so daß einerseits eine sehr platzsparende Anordnung gewonnen werden kann und daß andererseits Zubehörteile platzsparend unmittelbar parallel zur Oberseite des Gerätes aufbewahrt werden können.A very particularly advantageous embodiment is obtained when the dimensions of the handle are adapted to the outer contour of the high-pressure cleaning device in such a way that the handle with its part having the receptacles can be folded parallel to the top of the device. In the folded or folded position the part of the handle facing the free end and the receptacles arranged thereon for accessories lie parallel to and close to the top, so that on the one hand a very space-saving arrangement can be obtained and that on the other hand space-saving accessories directly parallel to Top of the device can be stored.

Dabei ist es vorteilhaft, daß das freie Ende des Handgriffs bei umgelegtem Halter nicht nach hinten über das Hochdruckreinigungsgerät hervorsteht; dies trägt dazu bei, den Handgriff insgesamt im wesentlichen innerhalb der Umrisse des Hochdruckreinigungsgerätes unterzubringen und erlaubt es insbesondere auch, das Hochdruckreinigungsgerät hochkant aufzustellen.It is advantageous that the free end of the handle does not protrude rearward over the high-pressure cleaning device when the holder is folded down; this contributes to generally accommodating the handle essentially within the outline of the high-pressure cleaning device and in particular also allows the high-pressure cleaning device to be placed upright.

Eine besonders günstige Raumaufteilung ergibt sich, wenn das Hochdruckreinigungsgerät und der Handgriff zwischen der Anlenkstelle des Handgriffs am Hochdruckreinigungsgerät und der hinteren oberen Kante des Hochdruckreinigungsgerätes gleichermaßen eine gebogene Kontur aufweisen. Der umgeklappte Handgriff schmiegt sich dann an die Kontur des Hochdruckreinigungsgerätes an und ist besonders platzsparend untergebracht, wenn er umgeklappt ist.A particularly favorable division of space results if the high-pressure cleaning device and the handle between the articulation point of the handle on the high-pressure cleaning device and the rear upper edge of the high-pressure cleaning device likewise have a curved contour. The folded handle then hugs the contour of the high-pressure cleaning device and is particularly space-saving when it is folded down.

Günstig ist es, wenn der Handgriff in seiner auf die Oberseite des Hochdruckreinigungsgerätes geklappten Position einen Schalter auf der Oberseite des Hochdruckreinigungsgerätes abdeckt. Beispielsweise kann der Handgriff in diesem Bereich plattenförmig ausgebildet sein. Dadurch wird eine unbeabsichtigte Betätigung des Schalters verhindert, bis der Handgriff in die ausgeklappte Position umgelegt worden ist.It is expedient if the handle covers a switch on the top of the high-pressure cleaning device in its position folded onto the top of the high-pressure cleaning device. For example, the handle can be plate-shaped in this area. This prevents the switch from being operated unintentionally until the handle has been folded into the extended position.

Bei einer bevorzugten Ausführungsform weist der Handgriff im Bereich seiner Lagerung einen im wesentlichen koaxial zur Schwenkachse verlaufenden Griffsteg auf. Dadurch kann das Hochdruckreinigungsgerät auch bei umgelegtem Handgriff hochkant getragen werden, beispielsweise beim Transport über Treppen.In a preferred embodiment, the handle has, in the region of its mounting, a handle web which runs essentially coaxially to the pivot axis. As a result, the high-pressure cleaning device can be carried upright even when the handle is folded, for example when transporting up stairs.

Weiterhin ist es vorteilhaft, wenn die der Anlenkstelle des Handgriffs gegenüberliegende Rückseite des Hochdruckreinigungsgerätes als Standfläche für das gegenüber der Arbeitsstellung um 90° geschwenkte Hochdruckreinigungsgerät ausgebildet ist. Dadurch läßt sich dieses hochkant aufstellen, wobei dann bei umgeklapptem Handgriff die Aufnahmen im wesentlichen senkrecht nach oben stehen, also von oben her beschickt werden können. Damit ergibt sich eine besonders günstige Aufbewahrungsposition, die wenig Standfläche benötigt und in der die Aufnahmen für Zubehör besonders gut zugänglich sind.Furthermore, it is advantageous if the rear side of the high-pressure cleaning device opposite the articulation point of the handle is designed as a standing surface for the high-pressure cleaning device pivoted by 90 ° with respect to the working position. This allows it to be placed upright, with the receptacles then being essentially vertically upward when the handle is folded down, that is to say they can be loaded from above. This results in a particularly favorable storage position that requires little floor space and in which the receptacles for accessories are particularly accessible.

Das in der Zeichnung dargestellte fahrbare Hochdruckreinigungsgerät umfaßt ein Gehäuse 1, an dessen hinterem unteren Ende auf gegenüberliegenden Seiten Laufräder 2 gelagert sind. Diese stehen nach unten und nach hinten über. In der Arbeitsstellung stützt sich das Gehäuse 1 über diese Laufräder 2 und eine Stütze 4 an der Unterseite 3 des Gehäuses am Boden 5 ab. An der Rückseite 6 ist eine Stellfläche 7 mit den Laufrädern 2 so ausgerichtet, daß das Gehäuse 1 auch um 90° verschwenkt hochkant auf eine Abstützfläche aufgestellt werden kann, die durch die Stellfläche 7 einerseits und die beiden Laufräder 2 andererseits gebildet wird.The mobile high-pressure cleaning device shown in the drawing comprises a housing 1, at the rear lower end of which wheels 2 are mounted on opposite sides. These protrude downwards and backwards. In the working position, the housing 1 is supported by these impellers 2 and a support 4 on the underside 3 of the housing on the bottom 5. At the rear 6, a footprint 7 is aligned with the impellers 2 so that the housing 1 can also be pivoted upright on a support surface, which is formed by the footprint 7 on the one hand and the two impellers 2 on the other hand.

In dem Gehäuse 1 sind in an sich bekannter Weise die wesentlichen Aggregate eines Hochdruckreinigungsgerätes untergebracht, also insbesondere eine Pumpe und ein diese Pumpe antreibender Elektromotor, außerdem sind im Gehäuse 1 Anschlüsse für die Zufuhr des zu fördernden Reinigungsmediums und für die Abgabe vorgesehen.In the housing 1, the essential units of a high-pressure cleaning device are accommodated in a manner known per se, that is to say in particular a pump and a pump Pump driving electric motor, in addition 1 connections are provided in the housing for the supply of the cleaning medium to be pumped and for the delivery.

An der Oberseite 8 des Gehäuses 1 befindet sich ein Schalter 9 zum Ein- und Ausschalten des die Pumpe antreibenden Elektromotors.On the top 8 of the housing 1 there is a switch 9 for switching the electric motor driving the pump on and off.

Die Kontur des Gehäuses 1 ist in dem dargestellten Ausführungsbeispiel so gewählt, daß sie von einem den Laufrädern 2 gegenüberliegenden vorderen Ende 10 bis zu der Stellfläche 7 einen Bogen ausbildet, der im Bereich des vorderen Endes 10 stärker gekrümmt ist als in dem zur Stellfläche 7 auslaufenden Teil.The contour of the housing 1 is chosen in the illustrated embodiment so that it forms an arc from a front end 10 opposite the wheels 2 to the footprint 7, which is more curved in the area of the front end 10 than in the tapering to the footprint 7 Part.

Im Bereich des vorderen Endes 10 ist am Gehäuse 1 um eine parallel der Drehachse der Laufräder 2 verlaufende Schwenkachse ein Handgriff 11 schwenkbar angelenkt, der zwei parallelverlaufende Schenkel 12, 13 umfaßt, die jeweils an ihren Enden durch einen Griffsteg 14 beziehungsweise 15 miteinander verbunden sind. Der gehäusenahe Griffsteg 14 ist dabei koaxial zur Schwenkachse des Handgriffs angeordnet, umgibt also praktisch diese Schwenkachse. Eine weitere Verbindung erfahren die beiden Schenkel 12 und 13 durch eine Verbindungsplatte 16, die sich an den vorderen Griffsteg und eine ihm benachbarte Grifföffnung 17 anschließt.In the area of the front end 10, a handle 11 is pivotally articulated on the housing 1 about a pivot axis running parallel to the axis of rotation of the running wheels 2, which comprises two parallel legs 12, 13, each of which is connected to one another at its ends by a handle web 14 or 15. The handle web 14 close to the housing is arranged coaxially to the pivot axis of the handle, so it practically surrounds this pivot axis. The two legs 12 and 13 experience a further connection by means of a connecting plate 16 which adjoins the front handle web and a handle opening 17 adjacent to it.

Die beiden Schenkel 12 und 13 des Handgriffs 11 sind in ihrer Längsrichtung abgebogen beziehungsweise abgewinkelt ausgebildet, so daß sich ein erster bogenförmiger Abschnitt 18 an den Griffsteg 14 anschließt, der dann unter Ausbildung eines Winkels in einen geradlinigen zweiten Abschnitt 19 übergeht, der sich bis zum Griffsteg 15 erstreckt.The two legs 12 and 13 of the handle 11 are bent or angled in their longitudinal direction, so that a first arcuate section 18 connects to the handle web 14, which then under Formation of an angle merges into a rectilinear second section 19 which extends to the handle bar 15.

Im Übergangsbereich bildet die Unterseite des Handgriffs 11 eine Stütze 20, gegebenenfalls kann in diesem Bereich ein zusätzlicher Vorsprung am Handgriff 11 diese Stütze 20 ausbilden.In the transition area, the underside of the handle 11 forms a support 20; if necessary, an additional projection on the handle 11 can form this support 20 in this area.

Durch diese Ausformung ruht der Handgriff 11 im ausgeschwenkten Zustand (Figur 1) mit der Stütze 20 am Boden 5, so daß der geradlinige Abschnitt 19 von dieser Stützstelle schräg nach oben absteht. Aus dieser Position heraus kann ein Benutzer das Gehäuse 1 verfahren, indem er den Handgriff an dem Griffsteg 15 faßt und nach oben anhebt, dabei wird auch das vordere Ende 10 des Gehäuses 1 angehoben; das Gehäuse ist dann auf den Laufrädern 2 verfahrbar.As a result of this configuration, the handle 11 rests in the pivoted-out state (FIG. 1) with the support 20 on the base 5, so that the straight section 19 protrudes obliquely upwards from this support point. From this position, a user can move the housing 1 by grasping the handle on the handle bar 15 and lifting it up, the front end 10 of the housing 1 also being raised; the housing is then movable on the wheels 2.

Zur Aufbewahrung des Hochdruckreinigungsgerätes kann der Handgriff 11 auf das Gerät zurückgeklappt werden. Aufgrund der gebogenen beziehungsweise abgewinkelten Formgebung des Handgriffs 11 paßt sich dieser im abgewinkelten Zustand eng an die bogenförmige Kontur des Gehäuses 1 auf deren Oberseite an, der Abschnitt 19 liegt bei eingeklapptem Handgriff 11 horizontal, das heißt parallel zur Unterseite 3 und damit im wesentlichen auch parallel zur Oberseite 8 (Figur 2). Die Länge des Handgriffs 11 ist dabei so gewählt, daß er nicht nach hinten über die Stellfläche 7 hervorsteht.To store the high-pressure cleaning device, the handle 11 can be folded back onto the device. Due to the curved or angled shape of the handle 11, it fits closely in the angled state to the arcuate contour of the housing 1 on its upper side, the section 19 lies horizontally when the handle 11 is folded, that is to say parallel to the underside 3 and thus essentially also parallel to the top 8 (Figure 2). The length of the handle 11 is chosen so that it does not protrude rearward over the footprint 7.

In dieser eingeklappten Position benötigt das Hochdruckreinigungsgerät wenig Platz, der Platzbedarf wird im wesentlichen durch die Abmessungen des Gehäuses gegeben, der Handgriff erhöht diese Abmessungen nur unwesentlich.In this folded position, the high-pressure cleaning device takes up little space, the space requirement essentially becomes given by the dimensions of the housing, the handle increases these dimensions only slightly.

Das Gehäuse 1 läßt sich auch hochkant aufbewahren, wenn der Handgriff 11 eingeklappt ist. Dazu kann das Gehäuse 1 am Griffsteg 14 ergriffen und hochkant aufgestellt werden, das Gerät steht dann einerseits auf der Stellfläche 7 und andererseits auf den Laufrädern 2, wobei der Abschnitt 19 des Handgriffs 11 dann senkrecht neben dem Gerät angeordnet ist.The housing 1 can also be stored upright when the handle 11 is folded. For this purpose, the housing 1 can be gripped on the handle bar 14 and placed upright, the device then stands on the one hand on the standing surface 7 and on the other hand on the wheels 2, the section 19 of the handle 11 then being arranged vertically next to the device.

Der eingeklappte Handgriff 11 deckt mit seiner Verbindungsplatte 16 den Schalter 9 auf der Oberseite 8 des Gehäuses 1 ab, so daß dieser nur betätigt werden kann, wenn der Handgriff 11 ausgeklappt ist.The folded handle 11 covers with its connecting plate 16, the switch 9 on the top 8 of the housing 1, so that it can only be actuated when the handle 11 is folded out.

Jeweils an der Außenseite jedes Schenkels 12, 13 befindet sich eine Aufnahmehülse 21 für eine Hochdruckreinigungspistole oder für ein Strahlrohr oder einen anderen rohrförmigen Gegenstand. Diese Aufnahmehülse 21 wird durch an die Außenseite der Schenkel 12, 13 angeformte, abgebogene Lappen 22 gebildet. Bei ausgeklapptem Handgriff 11 ist die Aufnahmehülse 21 schräg nach oben gerichtet, der Benutzer kann also in sehr bequemer Weise ein Strahlrohr oder eine Hochdruckreinigungspistole einstecken beziehungsweise herausziehen. Bei einer in der Zeichnung nicht dargestellten, abgewandelten Ausführungsform könnte der Abschnitt 19 auch senkrecht nach oben abstehen, so daß dann auch die Aufnahmehülse nicht schräg nach oben gerichtet wäre, sondern senkrecht nach oben. Auch in diesem Falle könnte ein rohrförmiger Gegenstand leicht in die Aufnahme eingeschoben werden. Eine schräg nach oben verlaufende Anordnung des Abschnittes 19 ist allerdings besonders vorteilhaft, da eine solche Anordnung für den Benutzer besonders leicht zugänglich ist.On the outside of each leg 12, 13 there is a receiving sleeve 21 for a high-pressure cleaning gun or for a jet pipe or another tubular object. This receiving sleeve 21 is formed by bent flaps 22 formed on the outside of the legs 12, 13. When the handle 11 is extended, the receiving sleeve 21 is directed obliquely upward, so the user can insert or remove a jet pipe or a high-pressure cleaning gun in a very convenient manner. In a modified embodiment, not shown in the drawing, the section 19 could also protrude vertically upwards, so that the receiving sleeve would then also not be directed obliquely upwards, but vertically upwards. In this case, too, a tubular object could easily be inserted into the receptacle. An obliquely upward arrangement of the Section 19 is particularly advantageous, however, since such an arrangement is particularly easily accessible to the user.

Oberhalb der Verbindungsplatte 16 ist eine Aufnahme für eine Waschbürste 23 angeordnet. Dazu sind an beiden Längskanten der Verbindungsplatte 16 nach oben abstehende L-förmige Schienen 24 angeformt, die zusammen mit der Verbindungsplatte 16 an beiden Enden zur jeweils gegenüberliegenden Seite hin offene Nuten 25 ausbilden. In diese Nuten läßt sich eine Borstenplatte 26 der Waschbürste 23 einschieben. In die Verbindungsplatte 16 kann eine Ausnehmung 27 eingeformt sein, in die der Rohranschluß der Waschbürste 23 paßt, wenn die Waschbürste 23 in die Aufnahme eingeschoben ist.A receptacle for a washing brush 23 is arranged above the connecting plate 16. For this purpose, L-shaped rails 24 projecting upwards are formed on both longitudinal edges of the connecting plate 16 and, together with the connecting plate 16, form open grooves 25 at both ends on the opposite side. A bristle plate 26 of the washing brush 23 can be inserted into these grooves. A recess 27 can be formed in the connecting plate 16, into which the pipe connection of the washing brush 23 fits when the washing brush 23 is pushed into the receptacle.

Dem Benutzer steht daher im Betrieb eine nach oben gerichtete und daher leicht zugängliche Ablage für diverse Zubehörteile zur Verfügung. Dasselbe gilt für den Ruhezustand, wenn der Handgriff auf das Gerät zurückgeklappt ist, denn dann sind die Aufnahmen ebenfalls ohne weiteres zugänglich, sie sind horizontalgerichtet bei in Arbeitsposition stehendem Hochdruckreinigungsgerät und vertikal bei hochkant aufgestelltem Hochdruckreinigungsgerät. Insgesamt ergibt sich damit sowohl ein geringer Platzbedarf bei der Aufbewahrung als auch eine gute Handhabbarkeit des Gerätes im Betrieb.The user therefore has an upward-facing and therefore easily accessible storage area for various accessories. The same applies to the idle state when the handle on the device is folded back, because then the recordings are also easily accessible, they are horizontally oriented with the high-pressure cleaning device in the working position and vertically with the high-pressure cleaning device set upright. Overall, this results in both a small space requirement for storage and good handling of the device in operation.
