Unter einer "Lenkschwenkachse" soll dabei insbesondere eine Schwenkachse verstanden werden, um die der Wälzkörper schwenken kann, um neben seiner Wälzbewegung einer gekrümmten Bahn folgen zu können. Dabei weist die Lenkschwenkachse vorzugsweise einen Winkel zwischen 80° und 100° und vorzugsweise von ca. 90° zu einer Wälzachse und zu einer Geräteabstützfläche auf.

If the device housing 10 is removed from the receiving area 28 of the pedestal, this can advantageously be transported by means of a strap handle 58 arranged on an upper side of the device housing 10 ( FIG. 3 ).

An der Oberseite des Gerätegehäuses 10 ist ferner ein Anschluss 60 für eine Hochdruckschlauchvorrichtung vorgesehen (Figur 4, 5, 8). Die Hochdruckschlauchvorrichtung umfasst einen als Hochdruckschlauch ausgebildeten Spiralschlauch 36, der schraubendruckfederartig ausgebildet und zur elastischen Verformung vorgesehen ist. In unbelastetem Zustand liegen Spiralwindungen des Spiralschlauchs 36 nahezu direkt aneinander an und die Spiralwindungen sind im Wesentlichen koaxial um eine im Wesentlichen senkrecht zur Geräteabstützfläche 22 ausgerichtete Achse 62 angeordnet (Figur 4). In belastetem Zustand kann sich ein Abstand zwischen den Spiralwindungen gegenüber dem unbelasteten Zustand um ein mehrfaches vergrößern, so dass ein Abstand einer an einem dem Anschluss 60 abgewandten Ende des Spiralschlauchs 36 angeordneten Hochdruckpistole 64 zum Gerätegehäuse 10 um ein Mehrfaches vergrößert werden kann (Figur 5). Mit zunehmender Länge muss eine Bedienperson eine äquivalente Kraft aufbringen, die abhängig von der Formsteifigkeit des Spiralschlauchs 36 ist. Der Spiralschlauch 36 ist bei seiner Herstellung unter Wärmeeinwirkung dauerhaft in seine Form gebracht, so dass bei einem späteren Betriebseinsatz sich dieser durch innere Spannkraft grundsätzlich stets nach Aufhebung einer Kräfteeinwirkung wieder in seine in Figur 4 dargestellte Grundstellung zurückstellt. Vorteilhaft ist an einer Seitenwand des Gerätegehäuses 10 eine Halteeinrichtung 66 für die Hochdruckpistole 64 angeordnet, wie dies in Figur 4 angedeutet ist, in die die Hochdruckpistole 64 mit ihrem Strahlrohr 68 eingeschoben und gesichert werden kann, so dass die Hochdruckpistole 64 und der Spiralschlauch 36 bei einem Transport am Gerätegehäuse 10 in einer gesicherten Position verbleiben können und ein Entfernen des Spiralschlauchs 36 und der Hochdruckpistole 64 vermieden werden kann. Grundsätzlich ist auch denkbar, dass am Gerätegehäuse 10, insbesondere an dessen Oberseite, eine Halte- und/oder Aufbewahrungseinrichtung speziell für den Spiralschlauch 36 vorgesehen ist.At the top of the device housing 10, a connection 60 is further provided for a high-pressure hose device ( FIG. 4 . 5 , 8th). The high-pressure hose device comprises a spiral hose 36 designed as a high-pressure hose, which is designed like a helical compression spring and is provided for elastic deformation. In the unloaded state spiral spirals of the spiral tube 36 are almost directly adjacent to each other and the spiral turns are arranged substantially coaxially about an axis 62 oriented substantially perpendicular to the device support surface 22 axis ( FIG. 4 ). In the loaded state, a distance between the spiral turns with respect to the unloaded state can increase by a multiple, so that a distance between a high pressure gun 64 arranged at an end of the spiral hose 36 facing away from the connection 60 can be increased by a multiple. FIG. 5 ). As the length increases, an operator must apply an equivalent force, which is dependent upon the stiffness of the spiral tube 36. The spiral tube 36 is permanently brought into its shape during its production under the action of heat, so that in a later operational use of this principle by internal clamping force always after cancellation of a force back into his in FIG. 4 resets the displayed basic position. Advantageously, a holding device 66 for the high-pressure gun 64 is arranged on a side wall of the device housing 10, as shown in FIG FIG. 4 is indicated, into which the high-pressure gun 64 can be inserted and secured with its jet pipe 68, so that the High-pressure gun 64 and the spiral tube 36 may remain in a secure position during transport on the device housing 10 and removal of the spiral tube 36 and the high-pressure gun 64 can be avoided. In principle, it is also conceivable that a holding and / or storage device is provided specifically for the spiral hose 36 on the device housing 10, in particular on its upper side.

Mit einer entsprechenden Materialkomposition wird in spiraliger Form ein besonders günstiges Rückstellvermögen erreicht, d.h. dass als Richtwert mit 5 m effektiver Schlauchlänge 2,5 m Arbeitslänge erzielt werden kann, ohne dass dabei das Rückstellvermögen des Spiralschlauchs 36 dauerhaft beschädigt wird.With a suitable material composition, a particularly favorable resilience is achieved in spiral form, i. that as a guideline with 5 m effective hose length 2.5 m working length can be achieved without causing the resilience of the spiral hose 36 is permanently damaged.

Das System mit dem Hochdruckreinigungsgerät und dem Spiralschlauch 36 ist in der Weise ausgelegt, dass bei dem auf einem Boden stehenden Hochdruckreinigungsgerät mit montiertem Spiralschlauch 36, dieser mit seinem dem Hochdruckreinigungsgerät abgewandten Ende, ausgehend von einer unbelasteten Stellung, senkrecht nach oben entlang der Achse 62 auf einen Abstand von mindestens 2,5 m zum Boden geführt werden kann, bevor eine dadurch innerhalb des Spiralschlauchs 36 resultierende Spannkraft eine Gewichtskraft des Hochdruckreinigungsgeräts übersteigt, so dass insbesondere vorteilhaft vermieden werden kann, dass bei einer Arbeit über Kopf das Hochdruckreinigungsgerät unerwünscht vom Boden abgehoben wird.The system with the high-pressure cleaner and the spiral hose 36 is designed in such a way that in the standing on a floor high-pressure cleaner with mounted spiral hose 36, this with its high pressure cleaning device remote end, starting from an unloaded position, vertically upwards along the axis 62 a distance of at least 2.5 m to the ground can be performed before a resultant within the spiral tube 36 clamping force exceeds a weight of the high-pressure cleaner, so that in particular can be advantageously avoided that when working overhead the high-pressure cleaner is lifted undesirable from the ground ,
