Abstract

PCT No. PCT/EP92/00347 Sec. 371 Date Sep. 10, 1993 Sec. 102(e) Date Sep. 10, 1993 PCT Filed Feb. 19, 1992 PCT Pub. No. WO92/16313 PCT Pub. Date Oct. 1, 1992.In order, on the one hand, to be able to use a high-pressure cleaning device comprising a high-pressure pump, a liquid supply and a pressure line for the liquid supplied by the pump as well as a housing surrounding the pump, in the usual way as a portable device and on the other hand, however, to facilitate transport without increasing the overall dimensions, it is proposed that rollers be arranged on the underside of the housing in the area of a side edge and that a handle insertable into the housing be mounted therein, the handle being shiftable between an inserted position in the housing and an extended position and securable in both these positions.

Description

Die Erfindung betrifft ein Hochdruckreinigungsgerät mit einer Hochdruckpumpe, einer Flüssigkeitszufuhr und einer Druckleitung für die von der Pumpe geförderte Flüssigkeit, mit einem die Pumpe umgebenden Gehäuse, an dessen Unterseite im Bereich einer Seitenkante Rollen und an dem ein Griff angeordnet sind.The invention relates to a high-pressure cleaning device with a high-pressure pump, a liquid supply and a pressure line for the liquid conveyed by the pump, with a housing surrounding the pump, on the underside of which rollers in the region of a side edge and on which a handle are arranged.

Hochdruckreinigungsgeräte werden in zunehmendem Maße als kleine, tragbare Geräte ausgeführt, die auch von Privatpersonen benutzt werden. Es ist bekannt, derartige Geräte mit einem Tragegriff auszubilden, so daß sie zum jeweiligen Einsatzort getragen werden können.High-pressure cleaning devices are increasingly being designed as small, portable devices that are also used by private individuals. It is known to design such devices with a handle so that they can be carried to the respective place of use.

Bei größeren Hochdruckreinigungsgeräten, deren Gewicht relativ hoch ist, ist diese Art des Transportes zu anstrengend. Man hat daher derartige Hochdruckreinigungsgeräte im Bereich einer Seitenkante mit Rollen versehen, so daß die Hochdruckreinigungsgeräte mit Hilfe des Griffes an der Oberseite gekippt und dann auf diesen Rollen gefahren werden können (US-A-2 640 724; CH-A-573 777). Diese bekannten Reinigungs- oder Chemikalienauftraggeräte sind jedoch sehr groß und auch relativ kompliziert zu fahren, da sich die Griffe unmittelbar an der Oberseite des Gehäuses befinden.With larger high-pressure cleaning devices, the weight of which is relatively high, this type of transport is too strenuous. Such high-pressure cleaning devices have therefore been provided with rollers in the region of a side edge, so that the high-pressure cleaning devices can be tilted with the aid of the handle on the upper side and then driven on these rollers (US Pat. No. 2,640,724; CH-A-573,777). However, these known cleaning or chemical application devices are very large and also relatively complicated to drive, since the handles are located directly on the top of the housing.

Es ist Aufgabe der Erfindung, ein gattungsgemäßes Hochdruckreinigungsgerät so auszugestalten, daß es in einfacher Weise an den jeweiligen Einsatzort transportiert werden kann und daß trotzdem ein platzsparender Aufbau eingehalten werden kann, der zudem den konventionellen Transport des Gerätes durch Tragen ermöglicht.It is an object of the invention to design a generic high-pressure cleaning device in such a way that it can be transported to the respective place of use in a simple manner and that a space-saving construction can nevertheless be maintained, which also enables the device to be transported conventionally by carrying it.

Diese Aufgabe wird bei einem Hochdruckreinigungsgerät der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß der Griff zwischen einer in das Gehäuse eingeschobenen Stellung und einer ausgezogenen Stellung verschoben und in diesen beiden Stellungen fixiert werden kann.This object is achieved according to the invention in a high-pressure cleaning device of the type described in the introduction in that the handle can be moved between a position inserted into the housing and an extended position and can be fixed in these two positions.

Zum Transport wird der Griff aus dem Gehäuse herausgezogen und ermöglicht somit, das Gehäuse über die Rollen zu verkippen, so daß das Gehäuse mit Hilfe des herausgezogenen Griffes auf den Rollen verfahren werden kann. Am Einsatzort oder bei der Lagerung wird der Griff wieder in das Gehäuse eingeschoben, so daß die kleine Baugröße des Gehäuses nicht vergrößert wird. Zudem ist es möglich, den eingeschobenen Griff, der im Gehäuse fixiert ist, gleichzeitig als Tragegriff zu verwenden. Das Gerät kann dann in der herkömmlichen Weise durch Tragen transportiert werden.For transport, the handle is pulled out of the housing and thus enables the housing to be tilted over the rollers so that the housing can be moved on the rollers with the aid of the handle that is pulled out. At the place of use or during storage, the handle is pushed back into the housing so that the small size of the housing is not enlarged. It is also possible to use the inserted handle, which is fixed in the housing, as a carrying handle. The device can then be carried in the conventional manner by carrying it.

Vorteilhaft ist es, wenn der Griff als U-förmiger Bügel ausgebildet ist, dessen beide Schenkel in das Gehäuse einschiebbar sind.It is advantageous if the handle is designed as a U-shaped bracket, the two legs of which can be inserted into the housing.

Eine bevorzugte Ausführungsform ist dadurch gekennzeichnet, daß der U-förmige Bügel (15) aus zwei gleich aufgebauten, L-förmigen Teilen besteht, die im Griffbereich miteinander verbunden sind.A preferred embodiment is characterized in that the U-shaped bracket (15) consists of two identically constructed, L-shaped parts which are connected to one another in the grip area.

Dabei ist es günstig, wenn die Verbindung der beiden L-förmigen Teile durch Rastnasen und Rastaufnahmen erfolgt, die an jedem L-förmigen Teil nebeneinander angeordnet sind und beim Zusammenstecken jeweils mit der Rastausnehmung beziehungsweise Rastnase des anderen L-Teils zusammenwirken.It is advantageous if the connection of the two L-shaped parts is carried out by latching lugs and latching receptacles, which are arranged next to one another on each L-shaped part and interact with the latching recess or latching lug of the other L part when plugged together.

Eine besonders vorteilhafte Ausgestaltung ergibt sich, wenn der Griff in der eingeschobenen Stellung an einem festen Tragegriff an der Oberseite des Gehäuses anliegt oder in diesen eingeschoben ist. Das Gehäuse weist also einen eigenen stabilen Tragegriff auf, während der einschiebbare Griff nur in der ausgeschobenen Stellung Verwendung findet, bei welcher dieser Griff zum Verfahren des Gerätes dient. In der eingeschobenen Stellung liegt dagegen der Griff am Tragegriff an oder wird von diesem aufgenommen, so daß ein integrierter Tragegriff entsteht, der in den Abmessungen vollständig dem festen Tragegriff entspricht.A particularly advantageous embodiment is obtained when the handle is in the inserted position against a fixed handle on the top of the housing or is inserted into it. The housing thus has its own stable handle, while the retractable handle is only used in the extended position, in which this handle is used to move the device. In the inserted position, on the other hand, the handle rests on or is picked up by the handle, so that an integrated handle is formed which corresponds in its dimensions completely to the fixed handle.

Vorteilhaft ist es auch, wenn die Rollen Teil einer Walze sind, die zwischen den Rollen einen reduzierten Durchmesser aufweist. Auf diese Weise kann die Walze als ein Teil hergestellt werden, beispielsweise als Blasformteil. Ausserdem ermöglicht der reduzierte Durchmesser zwischen den Rollen die Anbringung von Lufteinlaß- oder Auslaßöffnungen in diesem Bereich, so daß trotz der Anordnung der Walze raumsparend Kühlluft zubeziehungsweise abgeführt werden kann.It is also advantageous if the rollers are part of a roller that has a reduced diameter between the rollers. In this way, the roller can be manufactured as one part, for example as a blow molded part. In addition, the reduced diameter between the rollers allows the installation of air inlet or outlet openings in this area, so that, despite the arrangement of the roller, cooling air can be removed or removed in a space-saving manner.

Im Betrieb wird das Gerät so aufgestellt, daß die Rollen als Stützfüße dienen. Zusätzlich kann vorgesehen sein, daß an der Unterseite des Gehäuses an der den Rollen abgewandten Seitenkante mindestens ein Stützfuß angeordnet ist, der mit den Rollen eine parallel zur Gehäuseunterseite angeordnete Standebene definiert.In operation, the device is set up so that the rollers serve as support feet. In addition, it can be provided that at least one support foot is arranged on the underside of the housing on the side edge facing away from the rollers, said support foot defining with the rollers a standing plane arranged parallel to the underside of the housing.

Dabei ist es vorteilhaft, wenn der Stützfuß seitlich über das Gehäuse vorsteht und zusammen mit Stützfüßen an der Seitenfläche des Gehäuses eine weitere, senkrecht zur ersten und parallel zu der Seitenwand verlaufende Standebene bildet. Es ist daher möglich, das Gehäuse entweder senkrecht aufzustellen, wobei das Gehäuse dann auf den Rollen und den Stützfüßen ruht, oder horizontal. Im letzteren Fall steht das Gehäuse auf den Stützfüßen an der Seitenwand, die Rollen sind dann an der Oberseite des in dieser Weise aufgestellten Gehäuses angeordnet.It is advantageous if the support foot protrudes laterally beyond the housing and, together with support feet, forms a further standing plane perpendicular to the first and parallel to the side wall on the side surface of the housing. It is therefore possible to either position the housing vertically, the housing then resting on the rollers and support feet, or horizontally. In the latter case, the housing stands on the support feet on the side wall, the rollers are then arranged on the top of the housing set up in this way.

Günstig ist es, wenn die Stützfüße aus einem gummielastischen Material bestehen.It is favorable if the support feet are made of a rubber-elastic material.

Die nachfolgende Beschreibung bevorzugter Ausführungsformen der Erfindung dient im Zusammenhang mit der Zeichnung der näheren Erläuterung. Es zeigen:

  • Figur 1 : eine Seitenansicht eines Hochdruckreinigungsgerätes mit eingeschobenem Griff;
  • Figur 2 : eine Ansicht ähnlich Figur 1 mit ausgezogenem Griff und in einer auf die Rollen verkippten Stellung des Hochdruckreinigungsgerätes;
  • Figur 3 : eine Draufsicht auf das Hochdruckreinigungsgerät der Figuren 1 und 2 und
  • Figur 4 : eine Seitenansicht des Hochdruckreinigungsgerätes der Figuren 1 bis 3 mit teilweise aufgebrochener Seitenwand.
The following description of preferred embodiments of the invention serves together menhang with the drawing of the detailed explanation. Show it:
  • Figure 1 is a side view of a high-pressure cleaning device with the handle inserted;
  • FIG. 2: a view similar to FIG. 1 with the handle pulled out and in a position of the high-pressure cleaning device tilted onto the rollers;
  • Figure 3 is a plan view of the high pressure cleaning device of Figures 1 and 2 and
  • Figure 4 is a side view of the high pressure cleaning device of Figures 1 to 3 with a partially broken side wall.

Das in der Zeichnung dargestellte Hochdruckreinigungsgerät umfaßt ein im wesentlichen quaderförmiges Gehäuse 1, in dem in an sich bekannter und daher nicht eigens dargestellter Weise eine Hochdruckpumpe angeordnet ist. Dieser Hochdruckpumpe wird über einen ersten Anschluß Reinigungsflüssigkeit zugeführt, die über einen zweiten Anschluß unter hohem Druck wieder abgegeben wird. An diesen zweiten Anschluß kann eine in der Zeichnung ebenfalls nicht dargestellte Hochdruckleitung angeschlossen werden, die zu einer Sprühpistole oder dergleichen führt.The high-pressure cleaning device shown in the drawing comprises an essentially cuboid housing 1, in which a high-pressure pump is arranged in a manner known per se and therefore not specifically shown. This high-pressure pump is supplied with cleaning fluid via a first connection, which is released again under high pressure via a second connection. A high-pressure line, also not shown in the drawing, can be connected to this second connection, which leads to a spray gun or the like.

Das Gehäuse 1 weist an seiner Unterseite 2 im Bereich einer Kante eine Walze 3 auf, die um eine parallel zu der Kante verlaufende Achse drehbar am Gehäuse gelagert ist und mit ihren beiden Endbereichen über die Kontur des Gehäuses 1 nach unten übersteht. In diesen Endbereichen ist der Aussendurchmesser der Walze größer als im Mittelbereich 5, so daß die Endbereiche die Form von Rollen 4 annehmen, die durch den im Umfang reduzierten Mittelbereich 5 miteinander verbunden sind. Die Durchmesserreduzierung des Mittelbereiches 5 bildet zusammen mit dem Gehäuse einen Spalt 6, der zum Ansaugen oder Ausstoßen von Kühlluft Verwendung findet.The housing 1 has on its underside 2 in the region of an edge a roller 3 which is rotatably mounted on the housing about an axis running parallel to the edge and projects with its two end regions downwards over the contour of the housing 1. In these end regions, the outer diameter of the roller is larger than in the central region 5, so that the end regions take the form of rollers 4, which are connected to one another by the reduced central region 5. The reduction in diameter of the central region 5 forms, together with the housing, a gap 6 which is used for sucking in or expelling cooling air.

An der gegenüberliegenden Kante der Unterseite 2 sind am Gehäuse 1 zwei Stützfüße 7 aus einem gummielastischen Material angeordnet, die nach unten gleich weit vorstehen wie die Rollen 4, so daß die Stützfüße 7 zusammen mit den Rollen 4 eine Standebene für das Gerät definieren.On the opposite edge of the underside 2, two support feet 7 made of a rubber-elastic material are arranged on the housing 1 and project downwards as far as the rollers 4, so that the support feet 7 together with the rollers 4 define a standing level for the device.

Die Stützfüße 7 ragen einerseits nach unten über das Gehäuse 1 hervor, andererseits aber auch über die anschliessende Seitenfläche 8. Diese Seitenfläche 8 trägt an der gegenüberliegenden Seite, also am oberen Ende des Gerätes, weitere Stützfüße 9, die ebenfalls aus gummielastischem Material bestehen können und die zusammen mit den Stützfüßen 7 eine weitere Standfläche definieren, die parallel zur Seitenfläche 8 verläuft.The support feet 7 protrude downwards over the housing 1, on the one hand, but also over the adjoining side surface 8. This side surface 8 carries on the opposite side, that is to say at the upper end of the device, further support feet 9, which can likewise consist of rubber-elastic material and which together with the support feet 7 define a further standing surface which runs parallel to the side surface 8.

An der Oberseite 10 ist an das Gehäuse 1 ein bügelförmiger, sich über die gesamte Breite erstreckender Tragegriff 11 angeformt, er verläuft parallel zur Achsenrichtung der Walze 3.A bracket-shaped carrying handle 11, which extends over the entire width, is formed on the upper side 10 of the housing 1 and runs parallel to the axial direction of the roller 3.

Der Tragegriff 11 ist an der Oberseite offen und nimmt einen Griff 12 auf, der zwei Schenkel 13 und 14 eines U-förmigen Bügels 15 miteinander verbindet. Die beiden Schenkel 13 und 14 sind beispielsweise als Rohre ausgebildet und tauchen von der Oberseite 10 her in das Gehäuse 1 ein. In diesem Bereich befindet sich eine rohrförmige Längsführung 16 für die Schenkel 13 und 14.The handle 11 is open at the top and receives a handle 12 which connects two legs 13 and 14 of a U-shaped bracket 15 with each other. The two legs 13 and 14 are designed, for example, as tubes and plunge into the housing 1 from the top 10. In this area there is a tubular longitudinal guide 16 for the legs 13 and 14.

Der U-förmige Bügel 15 kann aus zwei L-förmigen Teilen bestehen, die längs des eigentlichen Griffteiles miteinander verbunden sind. Die Verbindung kann beispielsweise dadurch erfolgen, daß an der Stirnfläche jedes L-förmigen Teils eine Rastnase und eine Rastausnehmung nebeneinander angeordnet sind. Wenn zwei gleich ausgebildete L-förmige Teile mit diesen Stirnseiten aufeinander zu geschoben werden, taucht jeweils die Rastnase des einen Teils in die Rastausnehmung des anderen Teils ein, so daß beim Zusammenschieben eine Rastverbindung der beiden L-förmigen Teile gebildet wird.The U-shaped bracket 15 can consist of two L-shaped parts which are connected to one another along the actual handle part. The connection can take place, for example, in that a latching lug and a latching recess are arranged next to one another on the end face of each L-shaped part. If two identically designed L-shaped parts with these end faces are pushed towards each other, the latching nose of one part is immersed in the latching recess of the other part, so that a snap connection of the two L-shaped parts is formed when pushed together.

Bei einer anderen Ausführungsform wird zwischen den beiden L-förmigen Teilen ein separates Verbindungsteil eingesetzt, welches mit beiden L-förmigen Teilen verbindbar ist.In another embodiment, a separate connecting part is used between the two L-shaped parts, which can be connected to both L-shaped parts.

Ein Vorteil dieser Ausbildung liegt insbesondere darin, daß identische L-förmige Teile verwendet werden können, um den U-förmigen Bügel 15 auszubilden.An advantage of this design is in particular that identical L-shaped parts can be used to form the U-shaped bracket 15.

Der Bügel 15 kann vollständig in das Gehäuse eingeschoben werden, in diesem Falle befindet sich der Griff 12 in dem oben offenen Tragegriff 11, insgesamt erhält man damit einen integrierten Tragegriff.The bracket 15 can be fully inserted into the housing, in this case the handle 12 is in the handle 11 which is open at the top, so that overall an integrated handle is obtained.

Der Bügel 15 kann aus dem Gehäuse 1 herausgezogen werden, wobei dann der Griff 12 im Abstand zur Oberseite 10 des Gehäuses 1 angeordnet ist, wie dies aus der Darstellung der Figur 2 ersichtlich wird. Durch die Längsführung 16 wird der Bügel 15 auch in der herausgezogenen Stellung geführt, so daß beim Verschwenken des Bügels 15 das Gehäuse 1 mitgenommen und auf den Rollen 4 verschwenkt wird, wie dies ebenfalls aus Figur 2 ersichtlich wird. In dieser Position kann das Gerät verfahren werden.The bracket 15 can be pulled out of the housing 1, the handle 12 then being arranged at a distance from the upper side 10 of the housing 1, as can be seen from the illustration in FIG. 2. Through the longitudinal guide 16, the bracket 15 is also guided in the pulled-out position, so that when the bracket 15 is pivoted, the housing 1 is taken along and pivoted on the rollers 4, as can also be seen in FIG. The device can be moved in this position.

Der Bügel 15 kann sowohl in der eingeschobenen Stellung als auch in der ausgezogenen Stellung im Gehäuse fixiert werden. Zu diesem Zweck trägt der Bügel an seiner Unterseite Vorsprünge 17, die mit in der Zeichnung nicht dargestellten Rasten am Gehäuse 1 zusammenwirken und somit eine lösbare Fixierung des Bügels im Gehäuse bewirken, und zwar einerseits in der eingeschobenen und andererseits in der ausgezogenen Stellung.The bracket 15 can be fixed in the housing both in the inserted position and in the extended position. For this purpose, the bracket carries on its underside projections 17 which cooperate with notches on the housing 1 not shown in the drawing and thus bring about a releasable fixation of the bracket in the housing, on the one hand in the inserted and on the other hand in the extended position lung.

Im Betrieb kann der Benutzer das Gerät bei eingeschobenem Bügel in herkömmlicher Weise als reines Tragegerät verwenden. Der Transport erfolgt durch Anheben des Gerätes am Tragegriff 11. Der Griff 12 ist dabei in den Tragegriff 11 vollständig integriert und stört in keiner Weise, insbesondere wird die Baugröße des Gerätes nicht vergrößert im Vergleich zu herkömmlichen tragbaren Geräten.In operation, the user can use the device in the conventional manner as a purely carrying device with the bow inserted. The device is transported by lifting the device on the handle 11. The handle 12 is completely integrated in the handle 11 and does not interfere in any way, in particular the size of the device is not increased in comparison to conventional portable devices.
