Description

Gegenstand der Erfindung ist ein Hochdruckreinigungsgerät mit einem Grundrahmen, an dem an einer Achse zwei voneinander beabstandete Räder angeordnet sind und der in seinem vorderen Bereich im Abstand von der Achse ein Auflageteil zur Auflage auf den Boden aufweist.The invention relates to a high-pressure cleaning device a base frame on which two spaced apart on an axis Wheels are arranged and the one in its front Area at a distance from the axis of a support part for support on the floor.

Derartige Gehäuse für Hochdruckreinigungsgeräte sind in vielfältigen Ausführungsformen bekannt geworden. Sie weisen einen Schubbügel auf, mit dem Ziel, daß der Hochdruckreiniger leicht verfahrbar ist.Such housings for high pressure cleaning devices are in various embodiments have become known. You point a push handle, with the aim that the pressure washer is easy to move.

Hierbei ist es bekannt, den Schubbügel werkstoffeinstückig mit dem Grundgehäuse des Hochdruckreinigungsgeräts zu verbinden, was jedoch mit dem Nachteil eines relativ sperrigen Aufbaus verbunden ist. Ein derartiger Hochdruckreiniger kann beispielsweise nicht in engen Kofferräumen von Kfz. untergebracht werden.It is known to use the push handle in one piece to connect the basic housing of the high-pressure cleaning device, but with the disadvantage of a relatively bulky structure connected is. Such a pressure washer can for example not in the tight trunk of a car. be accommodated.

Es ist ebenso bekannt, derartige Schubbügel lösbar an dem Grundgehäuse des Hochdruckreinigers anzuordnen. Bei dieser bekannten Ausführungsform besteht aber der Nachteil, daß der Schubbügel nur schwer lösbar an dem Hochdruckreiniger befestigbar ist.
Bei den bekannten Hochdruckreinigern ist es bekannt, den Schubbügel lösbar mit dem Grundgehäuse des Hochdruckreinigungsgeräts zu verbinden. Diese Verbindungsarten haben aber den Nachteil, daß die Höhe des Grundgehäuses auch bei abgenommenem Schubbügel so hoch ist, daß es nur schwer in engen Transporträumen zu stauen ist.It is also known to releasably arrange such push bars on the basic housing of the high-pressure cleaner. In this known embodiment, however, there is the disadvantage that the push bracket can be attached to the high-pressure cleaner only with difficulty.
In the known high-pressure cleaners, it is known to releasably connect the push bracket to the basic housing of the high-pressure cleaning device. However, these types of connections have the disadvantage that the height of the basic housing is so high, even when the push handle is removed, that it is difficult to stow in narrow transport spaces.

Ferner haben die bekannten Schubbügel den Nachteil, daß sie nicht aus einem gespritzten zargenartigen Kunststoffteil bestehen und deshalb nur mit hohen Herstellungskosten herzustellen sind. Es ist hierbei bekannt, die Schubbügel z.B. aus einem Metallteil zu fertigen, aus einem kombinierten Metall-Kunststoffteil und dergleichen mehr herzustellen.Furthermore, the known push bars have the disadvantage that they not from an injection molded frame-like plastic part exist and therefore only with high manufacturing costs are to be produced. It is known here to push the push bar e.g. to be made from a metal part, from a combined one To manufacture metal-plastic part and the like.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Hochdruckreinigungsgerät mit abnehmbarem Schubbügel der eingangs genannten Art so weiterzubilden, daß der Schubbügel als schalenartiges Teil leicht lösbar mit dem Grundgehäuse des Hochdruckreinigungsgeräts verbunden werden kann und daß das Hochdruckreinigungsgerät bei abgenommenem Schubbügel eine relativ geringe Höhe aufweist.The invention is therefore based on the object High pressure cleaning device with removable push handle at the entrance mentioned type so that the push handle as shell-like part easily detachable with the basic housing of the High pressure cleaning device can be connected and that High-pressure cleaning device with the push handle removed has a relatively low height.

Zur Lösung der gestellten Aufgabe ist die Erfindung dadurch gekennzeichnet, daß der Schubbügel aus einem schalenartigen Kunstoffteil mit zwei einander gegenüberliegenden und parallel zueinander liegenden Seitenwangen ausgebildet ist, welche Seitenwangen in ihrem oberen Bereich durch einen gemeinsamen, die Seitenwangen verbindenden Querholm miteinander verbunden sind.To achieve the object, the invention is thereby characterized in that the push bar from a shell-like Plastic part with two opposite and parallel side cheeks are formed, which Sidewalls in their upper area by a common, the cross member connecting the side bolsters connected to each other are.

Hierbei ist wichtig, daß die Verbindungsebene zwischen dem Schubbügel und dem Grundgehäuse des Hochdruckreinigungsgeräts möglichst nahe am Grundgehäuse ausgebildet ist. Diese Maßnahme führt dazu, daß bei abgenommenem Schubbügel das Grundgehäuse eine relativ geringe Bauhöhe aufweist.It is important that the connection level between the Push bar and the main housing of the high-pressure cleaning device is formed as close as possible to the basic housing. This measure leads to the fact that the basic housing is removed when the push handle is removed has a relatively low overall height.

Hierbei wird es bevorzugt, wenn die Verbindungsebene zwischen dem Schubbügel und der Auflageebene des Grundgehäuses noch unterhalb der abnehmbaren Haube für das Grundgehäuse liegt, weil hierdurch eine optimal niedrige Bauhöhe des Hochdruckreinigungsgeräts bei abgenommenem Schubbügel erreicht wird.It is preferred if the connection level between the push bar and the support level of the basic housing lies underneath the removable hood for the basic housing, because this ensures an optimally low overall height of the high-pressure cleaning device reached with the push handle removed.

In einer Weiterbildung der vorliegenden Erfindung ist es vorgesehen, daß bei abgenommenem Schubbügel weitere wichtige Teile des Hochdruckreinigungsgeräts zugänglich werden, die andernfalls nur sehr schwierig zugänglich sind.In a development of the present invention, it is provided that with the push handle removed, further important Parts of the high-pressure cleaning device become accessible otherwise they are very difficult to access.

Die leichte Demontierbarkeit des Schubbügels hat also den weiteren Vorteil, daß bei einer derartigen Montage die übrigen Teile des Hochdruckreinigungsgeräts, nämlich insbesondere die Halterung des Motorpumpenaggreggats am Grundgehäuse, leicht zugänglich werden.The easy disassembly of the push handle has it Another advantage that the rest of the assembly Parts of the high-pressure cleaning device, namely in particular the Bracket of the motor pump unit on the basic housing, light become accessible.

Besonders vorteilhaft ist es hierbei, wenn das vordere, mittlere Fusslager höheneinstellbar ausgebildet ist, so daß das Motorpumpenaggreggat durch die Einstellung an dem fuss-seitigen Lager verschwenkt werden kann, wobei die Schwenkachse im Bereich des hinteren Lagers liegt.It is particularly advantageous here if the front, middle foot bearing is height adjustable, so that Motor pump unit by the setting on the foot side Bearing can be pivoted, the pivot axis in Area of the rear bearing.

Damit ergibt sich der Vorteil, daß mit wenigen Teilen ein schwenkbares Motorpumpenaggreggat verwirklicht wird, welches in seiner Lage zu der darauf gesetzten Haube einstellbar ist.This has the advantage that a few parts pivotable motor pump unit is realized, which in its position to the hood placed on it is adjustable.

Im übrigen wird es auch noch bevorzugt, wenn in dem Grundgehäuse ein Chemikalientank integriert ist, der in das schalenartig ausgebildete Grundgehäuse als Hohlkörper mit einbezogen ist.Otherwise, it is also preferred if in the Basic housing is a chemical tank integrated into the shell-like basic housing with a hollow body is involved.

In einer Weiterbildung der vorliegenden Erfindung ist es im übrigen vorgesehen, daß am Schubbügel Lagerböcke angeordnet sind, zwischen denen eine Schlauchtrommel aufgenommen wird, und daß am Schubbügel ferner eine Ablageschale vorhanden ist, welche im unteren Bereich des Schubbügels angeordnet ist und die die Verwindungssteifigkeit des Schubbügels noch verbessert.In a development of the present invention, it is in rest provided that bearing blocks arranged on the push bracket are between which a hose reel is received, and that there is also a storage tray on the push bar, which is arranged in the lower area of the push bar and which further improves the torsional stiffness of the push handle.

In der Darstellung ist mit Bezugszeichen 1 ein Schubbügel dargestellt, der aus einem schalenartigen, mehrteiligen Kunststoffteil besteht.In the illustration, reference number 1 shows a push handle shown, which consists of a bowl-like, multi-part Plastic part is made.

Es handelt sich hierbei um eine vordere Kunststoffschale und um eine hintere Kunststoffschale, die über eine mittlere Trennebene miteinander verbunden sind, so daß also der Querholm 2 sowohl mit der wangenartigen linken Seite des Schubbügels als auch mit der wangenartigen rechten Seite des Schubbügels jeweils verbunden ist. Der Querholm 2 ist jedoch in vertikaler Richtung geteilt, so daß sich der Schubbügel in einen vorderen, schalenartigen Teil und in einen hinteren schalenartigen Teil unterteilt, wobei die Trennfuge zwischen den beiden Teilen etwa in vertikaler Ebene liegt. Die beiden schalenartigen Teile des Schubbügels sind über entsprechende Befestigungsschrauben miteinander verbunden, so daß die Verbindung steif und fest ausgebildet sind.It is a front plastic shell and a rear plastic shell over a middle one Parting plane are connected to each other, so that the cross member 2 with the cheek-like left side of the push bar as well also with the cheek-like right side of the push bar is connected in each case. The cross bar 2 is, however, vertical Divided direction so that the push bar is in a front, bowl-like part and into a rear bowl-like part divided, the parting line between the two parts approximately lies in the vertical plane. The two shell-like parts of the Push bars are via appropriate fastening screws interconnected so that the connection is stiff and firm are trained.

Die beiden Kunststoffteile des Schubbügels 1 sind hierbei in der Trennebene 41 miteinander verbunden, so wie dies in Figur 1 dargestellt ist. Der hintere Kunststoffteil 42 ist also wesentlich kleiner ausgebildet als der vordere Kunststoffteil 43, wobei die beiden Kunststoffteile 42,43 sich jeweils zu dem kompletten Schubbügel 1 im Bereich der Trennebene 41 vereinigen.The two plastic parts of the push bracket 1 are in here the parting plane 41 connected to one another, as shown in FIG. 1 is shown. The rear plastic part 42 is therefore designed much smaller than the front plastic part 43, the two plastic parts 42, 43 each belonging to the complete push handle 1 in the area of parting line 41 unite.

Im unteren Bereich des Schubbügels 1 ist hierbei eine Quertraverse angeordnet, die als Ablageschale 16 ausgebildet ist. Hierbei ist wichtig, daß diese Ablageschale werkstoffeinstückig mit den beiden symmetrisch zueinander angeordneten Kunststoffteilen 42,43 ausgebildet ist.In the lower area of the push bar 1 there is one Crossbar arranged, which is designed as a tray 16 is. It is important that this tray is made of one piece of material with the two arranged symmetrically to each other Plastic parts 42,43 is formed.

Hierdurch wird eine optimale Verwindungssteifigkeit des Schubbügels 1 insgesamt erreicht.This ensures an optimal torsional stiffness of the Push bar 1 reached in total.

Im oberen Bereich des Schubbügels (nämlich im Bereich des vorderen Kunststoffteils 43) ist hierbei gemäss Figur 3 eine Aufnahme 10 für die Aufnahme eines Lagerbocks 9 vorgesehen. In Figur 3 ist dieser Lagerbock demontiert und es ist ein deckelartiges Teil vorhanden, welches mit Hilfe von Schrauben 12 diese Aufnahme 10 verschließt.In the upper area of the push bar (namely in the area of the front plastic part 43) is here according to FIG Recording 10 provided for receiving a bearing block 9. In Figure 3, this bracket is disassembled and it is a cover-like Part available, which with the help of screws 12 closes this receptacle 10.

Im montierten Zustand wird an jedem Kunststoffteil 43 des Schubbügels 1 jeweils ein Lagerbock 9 mit Schrauben 12,12a montiert, der in der Lage ist, eine entsprechende Querachse einer nicht näher dargestellten Schlauchtrommel aufzunehmen. In the assembled state 43 of each plastic part Push bracket 1 each have a bearing block 9 with screws 12, 12a mounted, which is capable of a corresponding transverse axis record a hose reel, not shown.

Ist die Schlauchtrommel nicht eingehängt, dann bildet das gezeigte abgekröpfte Teil des Lagerbocks 9 eine Aufnahme für die Sprühlanze und ggf. für die Hochdruckleitung.If the hose reel is not hooked in, then this forms shown cranked part of the bearing block 9 a receptacle for the spray lance and possibly for the high pressure line.

Das Grundgehäuse 3 des Hochdruckreinigungsgeräts ist ebenfalls aus Kunststoff wannenartig ausgebildet und weist hierbei erhöhte Seitenwangen 14 im hinteren Bereich auf, die in diesem Bereich in einen Chemikalientank 13 übergehen, der in Seitenwangen 14 integriert ist und quer die Rückwand des Grundgehäuses 3 gemäss Figur 2 bildet.The basic housing 3 of the high-pressure cleaning device is also made of plastic tub-like and has here raised sidewalls 14 in the rear area, which in this Pass the area into a chemical tank 13, which in Sidewalls 14 is integrated and transversely the rear wall of the Basic housing 3 forms according to Figure 2.

Der obere Rand des Grundgehäuses 3 bildet eine schräg nach vorne geneigte Auflagefläche (Auflager 15), welche sich bogenförmig nach vorne und unten erstreckt und welche in ihrem vorderen Bereich in eine nach hinten geneigte Schrägfläche 31 übergeht, die einen Ausschnitt 32 im vorderen Bereich begrenzt.The upper edge of the basic housing 3 forms an oblique front inclined support surface (support 15), which are arched forward and downward and which in their front area into a backward inclined surface 31 passes, which delimits a cutout 32 in the front area.

Auf dieses schräg nach unten verlaufende Auflager 15 wird der Schubbügel 1 mit seinem unteren Ende gemäss Figur 1 aufgesetzt und mit jeweils an jeder Seite angeordneten zwei Schrauben 17,19 mit dem Grundgehäuse 3 leicht lösbar verbunden. Hierbei sind am Grundgehäuse 3 jeweils Gegenlager 18,20 angeordnet, in welche die Schrauben 17,19 jeweils eingreifen und dort leicht lösbar gehalten sind.On this obliquely downward bearing 15 is the Push bar 1 with its lower end placed according to Figure 1 and with two screws on each side 17,19 connected to the basic housing 3 easily detachable. Here counterbearing 18, 20 are arranged on the basic housing 3, in which engage the screws 17, 19 and lightly there are held releasably.

Diese Schrauben 17,19 (die jeweils paarweise vorhanden sind) sind also durch die vordere, mittlere und zentrale Ausnehmung des Schubbügels 1 leicht von vorne her zu erreichen, so daß der Schubbügel leicht abnehmbar ausgebildet ist.These screws 17, 19 (which are available in pairs) are through the front, middle and central recess the push bar 1 easy to reach from the front, so that the Push handle is designed to be easily removable.

Wichtig ist nun, daß bei Abnahme des Schubbügels 1 durch Lösen der Schrauben 17,19 die wichtigen Befestigungslager für die Befestigung des Motorpumpenaggreggats zugänglich werden.It is now important that when removing the push bar 1 by loosening the screws 17,19 the important mounting bearings for the Attachment of the motor pump unit be accessible.

Hierzu ist vorgesehen, daß im Grundgehäuse 3 das Motorpumpenaggreggat 7,8 fest mit zueinander fluchtenden gegeneinander gerichteten Achsen 22 versehen ist, wobei diese Achsstummel auf dem rückwärtigen Motordeckel des Motoraggreggates 7 befestigt sind. Die Achsen 22 greifen jeweils in Lagerungen 23 ein, die etwa kreiszylindrisch mit einer mittleren Ausnehmung ausgebildet sind, wobei die Lagerungen 23 entweder aus einem Elastomer-Material bestehen können, aus einem Hartgummi oder aus einem anderen schwingungsgedämpfen Material, wie z.B. einem Metallelement oder dergleichen mehr. Die Lagerungen 23 ihrerseits sind jeweils von oben her durch eine Halbschale 24 abgedeckt, wobei jede Halbschale 24 durch vordere und hintere Schrauben 25 an zugeordneten Befestigungsflächen am Grundgehäuse befestigt sind.For this purpose it is provided that the motor pump unit in the basic housing 3 7.8 firmly with each other in alignment Directed axes 22 is provided, these stub axles attached to the rear engine cover of the engine assembly 7 are. The axes 22 engage in bearings 23, respectively approximately circular cylindrical with a central recess are formed, the bearings 23 either from a Elastomer material can consist of a hard rubber or from another vibration-damping material, e.g. one Metal element or the like. The bearings 23 in turn are each from above through a half shell 24 covered, with each half shell 24 by front and rear Screws 25 on assigned mounting surfaces on Basic housing are attached.

Die vordere Abstützung des Motorpumpenaggreggats 7,8 erfolgt hierbei durch einen vorderen Fuß, der im wesentlichen als Auflageteil 27 zur Abstützung auf dem Boden ausgebildet ist. Dieses Auflageteil 27 weist eine Ausnehmung 28 auf, in welcher höheneinstellbar eine Einstellschraube 30 mit einer Mutter 29 gehalten ist.The front support of the motor pump unit 7.8 takes place here by a front foot, which is essentially as Support part 27 is formed for support on the floor. This support part 27 has a recess 28 in which an adjusting screw 30 with a nut 29 is adjustable in height is held.

Wird die Mutter 29 von der Einstellschraube 30 gelöst, dann kann das gesamte Motorpumpenaggreggat 7,8 nach oben hin herausgenommen werden, sofern die Halbschalen 24 an den als Drehlager ausgebildeten Lagern 21 entfernt werden.If the nut 29 is loosened from the adjusting screw 30, then the entire motor pump unit 7,8 can be removed upwards provided the half shells 24 to the as a pivot bearing trained bearings 21 are removed.

Wichtig ist, daß durch Verdrehung der Mutter 29 die Einstellschraube 30 in ihrer Höhe verändert ist, wobei gleichzeitig wesentlich ist, daß sich das Motorpumpenaggreggat 7,8 über ein Schwingungselement 44 auf dem Bodenlager 26 abstützt.It is important that the twist of the nut 29 Adjusting screw 30 is changed in height, whereby at the same time it is essential that the motor pump unit 7,8 via a vibration element 44 on the floor bearing 26 supports.

Auf diese Weise ist also gesorgt, daß das gesamte Motorpumpenaggreggat 7,8 im Grundgehäuse 3 gehalten ist und an lediglich 3 Befestigungspunkten aufgehängt ist. In this way it is ensured that the entire motor pump assembly 7,8 is held in the basic housing 3 and only 3 Attachment points is suspended.

Wird die Einstellschraube 30 in Pfeilrichtungen 33,34 eingestellt, dann verschwenkt das gesamte Motorpumpenaggreggat in der Pfeilrichtung 35 um die Achsen 22 als Drehlager. Auf diese Weise wird sichergestellt, daß das Motorpumpenaggreggat lagenrichtig zur Haube 4 des Hochdruckreinigungsgeräts eingestellt werden kann.If the adjusting screw 30 in the arrow directions 33, 34 set, then the entire motor pump unit swings in the arrow direction 35 about the axes 22 as a pivot bearing. On this ensures that the motor pump unit in the correct position for hood 4 of the high-pressure cleaning device can be adjusted.

Die Haube 4 deckt nämlich den vorderen Teil des Hochdruckreinigungsgeräts und insbesondere das Motorpumpenaggreggat 7,8 von vorne her ab, wobei die Haube mittels zweier voneinander beabstandeter Haubenfestigungen 37 an dem Auflager 15 des Grundgehäuses 3 befestigt ist. Die rückwärtige Befestigung der Haube 4 erfolgt hierbei im Bereich des Schubbügels 1 über die Befestigung 45.The hood 4 namely covers the front part of the high-pressure cleaning device and in particular the motor pump unit 7.8 from the front, with the hood using two from each other spaced hood fastenings 37 on the support 15 of the Basic housing 3 is attached. The rear attachment of the Hood 4 takes place in the area of the push bracket 1 via the Attachment 45.

Mit dem Motorpumpenaggreggat ist ferner ein Schaltkasten 38 verbunden, welcher die elektrischen Funktionsteile beinhaltet. An der Oberseite des Schaltkastens 38 ragt ein Schaltknopf 39 aus diesem heraus und greift durch einen Ausschnitt 40 durch die Haube 4 hindurch.A switch box 38 is also provided with the motor pump unit connected, which contains the electrical functional parts. A switch button 39 protrudes from the top of the switch box 38 out of this and reaches through a cutout 40 the hood 4 through.

Um nun das Hindurchgreifen dieses Schaltknopfes 39 auf dem Ausschnitt 40 in der Haube einstellen zu können, ist die beschriebene Schwenklagerung des Motorpumpenaggreggats 7,8 vorgesehen.To reach through this button 39 on the To be able to adjust cutout 40 in the hood is described pivot bearing of the motor pump unit 7.8 intended.

Der Vollständigkeit halber ist noch erwähnt, daß in ansich bekannter Weise an einer hinteren Achse 6 zwei voneinander beabstandete Räder 5 angeordnet sind, welche drehbar auf der Achse 6 gelagert sind, wobei diese Räder bevorzugt aus einem Kunststoffmaterial bestehen und einen entsprechenden gummielastischen Laufbelag tragen.For the sake of completeness it is mentioned that in itself known manner on a rear axle 6 two from each other spaced wheels 5 are arranged which are rotatable on the Axle 6 are mounted, these wheels preferably from one Plastic material and a corresponding rubber-elastic Wear tread.

Die Achse 6 ist gemäss Figur 1 ebenfalls mit einer halbschalenartigen Konstruktion mit der Unterseite des Grundgehäuses 3 verbunden, wobei das Grundgehäuse an seiner Unterkante 46 eine nach vorne geöffnete kreisrunde Aufnahme 47 ausbildet, in welche die Achse 6 etwa formschlüssig eingreift und mittels einer Halbschale 48 vor dem Heraus fallen gesichert ist, welche Halbschale 48 mittels einer Schraube 49 am Grundgehäuse 3 befestigt ist.The axis 6 is also according to Figure 1 with a half-shell Construction with the underside of the basic housing 3 connected, the basic housing on its lower edge 46 a circular receptacle 47 open towards the front, in which engages the axis 6 approximately positively and by means of a half shell 48 is secured against falling out, which Half-shell 48 by means of a screw 49 on the basic housing 3 is attached.

Vorteil der Erfindungsgemäss vorgeschlagenen Lösung ist also, daß ein relativ groß dimensionierter Schubbügel vorgesehen ist, der aus zwei schalenartigen Kunststoffteilen 42,43 besteht, welche zusammen den etwa U-förmigen Schubbügel 1 bilden, wobei der Verbindungsschenkel dieses U-förmigen Schubbügels 1 durch den Querholm 2 gebildet wird. Nachdem die Verbindungsebene zwischen dem Schubbügel 1 und dem Grundgehäuse 3 im Bereich eines schräg nach vorne geneigten Auflagers 15 angeordnet ist, welches Auflager möglichst dicht über dem Boden angeordnet ist, ergibt sich der Vorteil, daß einerseits bei montiertem Schubbügel eine günstige Kraftübertragung auf das Grundgehäuse 3 beim Schieben des Geräts gewährleistet ist und andererseits bei abgenommenem Schubbügel das Gerät eine geringe Bauhöhe aufweist.The advantage of the solution proposed according to the invention is therefore that a relatively large push handle is provided, that of two shell-like plastic parts 42,43, which together form the approximately U-shaped Form push bracket 1, the connecting leg of this U-shaped Push bracket 1 is formed by the cross member 2. After the connection level between the push bar 1 and the Basic housing 3 in the area of an inclined forward Support 15 is arranged, which support as close as possible is arranged above the floor, there is the advantage that on the one hand, a cheap one when the push handle is installed Power transmission to the basic housing 3 when pushing the Device is guaranteed and on the other hand when removed Push bar the device has a low overall height.

Weiterer Vorteil der vorliegenden Erfindung ist, daß der Schubbügel eine relativ gerade und vertikale (stehende) Lage hat, wobei seine Mittelachse also relativ senkrecht ausgerichtet ist und im wesentlichen auf der Achse des Fahrgestells fluchtet, so daß eine optimale Gewichtsverteilung gegeben ist. Damit wird dem ansich liegenden Gerät (mit liegenden Aggreggaten) der Charakter eines stehenden Geräts verliehen, weil der Schubbügel stehend ausgebildet ist und nicht schräg nach hinten geneigt ausgerichtet ist. Dies führt dazu, daß er also über der Fahrachse liegt. Another advantage of the present invention is that the Push bar a relatively straight and vertical (standing) position has, so its central axis is relatively perpendicular is aligned and essentially on the axis of the Chassis is aligned so that an optimal weight distribution given is. The device itself (with lying aggregates) the character of a standing device awarded because the push handle is designed upright and is not inclined at an angle to the rear. this leads to to the fact that it lies above the driving axis.
