Durch dieses einfache Verfahren zur Montage oder Demontage des Reinigungsfahrwagens kann dieser vom Benutzer ohne Werkzeug in kurzer Zeit und in Abhängigkeit von den jeweiligen Gegebenheiten des Anwendungsfalles umgebaut und dadurch individuell an die jeweiligen Bedürfnisse angepasst werden.With this simple method of assembling or disassembling the cleaning trolley, the user can convert it in a short time without tools and depending on the particular circumstances of the application and thus adapt it individually to the respective needs.

Außerdem ist von Vorteil, dass der Reinigungsfahrwagen, im Anschluss an seine Verwendung, einfach recycelbar ist. Dazu werden lediglich die Steckverbindungen des Stecksystems gelöst, und die Bauteile, aus denen der Reinigungsfahrwagen besteht, können getrennt voneinander entsorgt werden. Ein weiterer Vorteil des Stecksystems ist darin zu sehen, dass die in den vertikalen Stützpfeilern eingeführten Seiten- bzw. Trennwände eine geschlossene Oberfläche erzeugen, und der Innenraum des Reinigungsfahrwagens vor Einblicken und unbefugtem Zugriff geschützt ist. Parallel dazu entstehen nur sehr wenige und vor allem einfach zu reinigende Spalten und Schnittstellen. Das ist ein Vorteil gegenüber zum Beispiel von innen oder von außen aufgeschraubten Wänden, die entweder schwer zu montieren sind und/oder durch die hervorstehenden Schraubenverbindungen schwer zu reinigen sind.Another advantage is that the cleaning trolley can be easily recycled after use. All you have to do is loosen the plug-in connections of the plug-in system and the components that make up the cleaning trolley can be disposed of separately. Another advantage of the plug-in system can be seen in the fact that the side and partition walls introduced into the vertical support pillars create a closed surface, and the interior of the cleaning trolley is protected from prying eyes and unauthorized access. At the same time, there are only very few gaps and interfaces that are easy to clean. This is an advantage over, for example, walls screwed on from the inside or outside, which are either difficult to assemble and/or difficult to clean due to the protruding screw connections.

Insbesondere für professionelle Anwendungen muss der Reinigungsfahrwagen robust sein und eine ausreichende Stabilität aufweisen. Die separat erzeugten Stützpfeiler, die eine Art Skelett des Reinigungsfahrwagens bilden und die Seiten- und/oder Trennwände aufnehmen und bezogen auf die Grundplatte und die Abdeckplatte oder den oberen Rahmen fixieren, sind maßgeblich an der hohen Stabilität des Reinigungsfahrwagens beteiligt. Die Aufnahme der Seiten- und/oder Trennwände erfolgt in den Führungsnuten der Stützpfeiler. Die Montage oder Demontage der Seiten- und/oder Trennwände ohne Werkzeug ist dadurch besonders einfach durch Einschieben oder Herausziehen in oder aus den Führungsnuten zu erreichen, auch dann, wenn der Benutzer des Reinigungsfahrwagens kein oder nur wenig technisches Verständnis hat. Durch die Führungsnuten sind die Seiten- und/oder Trennwände exakt und dauerhaltbar zueinander positioniert.For professional applications in particular, the cleaning trolley must be robust and have sufficient stability. The separately produced support pillars, which form a kind of skeleton of the cleaning trolley and accommodate the side and/or partition walls and fix them in relation to the base plate and the cover plate or the upper frame, play a key role in the high stability of the cleaning trolley. The side and/or partition walls are accommodated in the guide grooves of the support pillars. The assembly or disassembly of the side and/or partition walls without tools is particularly easy to achieve by pushing or pulling them into or out of the guide grooves, even if the user of the cleaning trolley has little or no technical understanding. The side and/or partition walls are positioned precisely and durably in relation to one another by the guide grooves.

Ein ganz wesentlicher Vorteil ist jedoch, dass die Stützpfeiler durchgehend gleich gestaltet werden können, das heißt sowohl die Eckpfeiler als auch die Mittenpfeiler (bei einem 2-Abteil-Wagen) sind gleich und können nie falsch eingesetzt werden.A very important advantage, however, is that the support pillars can be designed the same throughout, i.e. both the corner pillars and the center pillars (in a 2-compartment car) are the same and can never be used incorrectly.

Als Seitenwände sind in diesem Zusammenhang Wände zu verstehen, die den Reinigungsfahrwagen außenseitig begrenzen und von außen sichtbar sind. Trennwände sind in diesem Zusammenhang Wände, die im Inneren des Reinigungsfahrwagens, also innenseitig der Seitenwände, angeordnet sind.In this context, side walls are understood to be walls that delimit the cleaning trolley on the outside and are visible from the outside. In this context, partition walls are walls that are arranged inside the cleaning trolley, that is to say on the inside of the side walls.

Die Stützpfeiler sind mit der Grundplatte und der Abdeckplatte oder dem oberen Rahmen durch Steck-, Klemm- oder Verriegelungseinrichtungen verbunden. Die genannten Einrichtungen sorgen dafür, dass Grundplatte, Abdeckplatte oder oberer Rahmen sowie Seiten- und/oder Trennwände sicher miteinander verbunden sind. Die Einrichtungen funktionieren kraft- und/oder formschlüssig. Die Verriegelungseinrichtung kann durch einen Formschluss gebildet sein, um die zuvor genannten Teile, aus denen der Reinigungsfahrwagen besteht, besonders verliersicher aneinander zu halten, auch dann, wenn der Reinigungsfahrwagen zum Beispiel unachtsam über einen unebenen Untergrund bewegt wird.The buttresses are connected to the base plate and cover plate or top frame by plug, clip or latch means. The devices mentioned ensure that the base plate, cover plate or top frame and side and/or partition walls are securely connected to one another. The devices function in a non-positive and/or positive manner. The locking device can by a form fit be formed in order to hold the above-mentioned parts that make up the cleaning carriage together in a particularly captive manner, even if the cleaning carriage is carelessly moved over an uneven surface, for example.

Die Stützpfeiler können mit der Grundplatte und der Abdeckplatte oder dem oberen Rahmen durch Rastverbindungen einschnappbar verbunden sein. Rastverbindungen sind einfach und kostengünstig herstellbar. Sie ermöglichen eine einfache Montage und eine ebenso einfache Demontage der miteinander verbundenen Teile. Üblicherweise bestehen Rastverbindungen aus Rastnasen an einem der miteinander zu verbindenden Teile, die hinter Hinterschneidungen des anderen Teils einschnappbar sind.The buttresses may be snap-fitted to the base plate and cover plate or top frame by snap-fit connections. Snap-in connections are easy and inexpensive to produce. They allow easy assembly and just as easy disassembly of the interconnected parts. Snap-in connections usually consist of snap-in lugs on one of the parts to be connected, which can be snapped in behind undercuts on the other part.

Der Formschluss kann eine Verriegelung umfassen wodurch die Verbindung noch sicherer und stabiler ausgeführt wird.The form fit can include a lock, making the connection even safer and more stable.

Gelangen zum Beispiel Keilriegel zur Anwendung, hat das den Vorteil, dass die Keilregel die miteinander zu verbindenden Teile während ihrer Montage zueinander ziehen und Spalte auf null reduzieren. Herstellungsbedingte oder montagebedingte Toleranzen sind dadurch auf ein Minimum reduziert.If, for example, wedge bolts are used, this has the advantage that the wedge rule pulls the parts to be connected together during assembly and reduces gaps to zero. Manufacturing-related or assembly-related tolerances are thereby reduced to a minimum.

Eine besonders einfache Betätigung der Rastverbindungen durch den Benutzer kann erreicht werden, wenn die Rastverbindungen für den Benutzer gut zugänglich am Reinigungsfahrwagen angeordnet sind. Dadurch ist die Handhabung bei Umbauten des Reinigungsfahrwagens oder bei dessen Demontage besonders einfach.A particularly simple actuation of the snap-in connections by the user can be achieved if the snap-in connections are arranged on the cleaning trolley in an easily accessible manner for the user. This makes handling particularly easy when converting the cleaning trolley or dismantling it.

Die Stützpfeiler sind bevorzugt auf ihrer der Grundplatte zugewandten Seite jeweils in einem Verbindungsschuh angeordnet, wobei die Stützpfeiler mittels der jeweiligen Verbindungsschuhe in die Grundplatte einschnappbar sind. Hierbei ist von Vorteil, dass die Endlosprofile einfach als Meterware hergestellt und abgelängt werden können. Es ist nicht erforderlich, diese anschließend aufwendig nachzubearbeiten und/oder Verbindungsvorrichtungen an den Endlosprofilen anzubringen um die Stützpfeiler direkt mit der Grundplatte oder der Abdeckplatte oder dem oberen Rahmen verbinden zu können. Die einfach als Meterware hergestellten Endlosprofile werden lediglich in den Verbindungsschuh eingeführt, mit Möglichkeiten, wie zuvor beschrieben, wobei der Verbindungsschuh die Verbindung zwischen dem Stützpfeiler und der Grundplatte bildet.The pillars are preferably each arranged in a connecting shoe on their side facing the base plate, it being possible for the pillars to be snapped into the base plate by means of the respective connecting shoes. The advantage here is that the endless profiles can be easily manufactured and cut to length by the meter. It is not necessary to rework them afterwards and/or connecting devices to the To attach endless profiles to be able to connect the support pillars directly to the base plate or the cover plate or the upper frame. The endless profiles, simply manufactured by the metre, are merely inserted into the connecting shoe, with possibilities as described above, the connecting shoe forming the connection between the support pillar and the base plate.

Jeder Verbindungsschuh kann zumindest eine Rastnase aufweisen, die in eine Hinterschneidung der Grundplatte einschnappbar ist. Durch einen solchen Verbindungsschuh wird die einfache und werkzeuglose Montage des Reinigungsfahrwagens begünstigt. Durch den Verbindungsschuh sind die Endlosprofile zerstörungsfrei lösbar mit der Grundplatte verbunden.Each connecting shoe can have at least one locking lug which can be snapped into an undercut of the base plate. Such a connection shoe facilitates the simple and tool-free assembly of the cleaning trolley. The endless profiles are non-destructively detachable connected to the base plate by the connecting shoe.

Die Stützpfeiler können, in einer Draufsicht betrachtet, im wesentlichen T-förmig ausgebildet sein, mit einem ins Innere des Reinigungsfahrwagens gerichteten Längssteg, der einem Quersteg im wesentlichen mittig zugeordnet ist. Solche T-förmigen Stützpfeiler sind einfach und kostengünstig herstellbar. Zum Beispiel als Endlosprofile, die aus einem metallischen oder einem polymeren Werkstoff bestehen.Viewed from above, the support pillars can be essentially T-shaped, with a longitudinal web which is directed towards the interior of the cleaning trolley and which is assigned essentially centrally to a transverse web. Such T-shaped pillars are easy and inexpensive to produce. For example, as endless profiles made of a metallic or polymeric material.

Durch das T-förmige Profil sind die zur Anwendung gelangenden Stützpfeiler besonders formstabil und durch ihre Form bestens geeignet, um an den einander abgewandten Enden des Querstegs jeweils eine Seiten- und/oder Trennwand aufnehmen zu können.Due to the T-shaped profile, the supporting pillars used are particularly dimensionally stable and, due to their shape, are ideally suited to being able to accommodate a side wall and/or partition wall at the opposite ends of the crossbar.

Die einander abgewandten Enden des Querstegs können jeweils eine Führungsnut zur Aufnahme von Seiten- und/oder Trennwänden aufweisen. Der Längssteg des Stützpfeilers bildet in einem solchen Anwendungsfall als Abstandhalter zwischen den in den Führungsnuten benachbart angeordneten Seiten- und/oder Trennwänden.The opposite ends of the transverse web can each have a guide groove for accommodating side walls and/or partitions. In such an application, the longitudinal web of the support pillar forms as a spacer between the side and/or partition walls arranged adjacently in the guide grooves.

Auch für technisch weniger geübte Benutzer ist durch die Führungsnuten in den Stützpfeilern sofort klar, wie die Seiten- und/oder Trennwände zu montieren sind. Die Handhabung des Reinigungsfahrwagens und dessen Anpassung an die jeweiligen Gegebenheiten des Anwendungsfalles ist dadurch besonders einfach möglich.The guide grooves in the support pillars make it immediately clear, even for less technically experienced users, how to mount the side and/or partition walls. The handling of the cleaning trolley and its adaptation to the respective circumstances of the application is particularly easy as a result.

Nach einer anderen Ausgestaltung können die Stützpfeiler, in einer Draufsicht betrachtet, im Wesentlichen L-förmig ausgebildet sein, mit einem ins Innere des Reinigungsfahrwagens gerichteten Längssteg und einem Quersteg.According to another embodiment, the support pillars, seen in a plan view, can be essentially L-shaped, with a longitudinal web directed towards the interior of the cleaning trolley and a transverse web.

Das freie Ende des Querstegs kann eine Führungsnut zur Aufnahme einer Seiten- und/oder Trennwand aufweisen.The free end of the transverse web can have a guide groove for receiving a side wall and/or partition.

Durch die L-förmige Gestalt entsteht nur am freien Ende die Führungsnut.Due to the L-shape, the guide groove only occurs at the free end.

Ebenfalls vorteilhaft ist, dass durch die Kombination von Seiten- und Trennwand oder die Kombination von zwei Trennwänden in der Mitte von einem Reinigungsfahrwagen mit zwei Abteilen ein freier Raum entsteht, durch den zum Beispiel elektrische Leitungen verlegt werden können. Diese Leitungen können eine Verbindung zwischen Akku-Packs und einem mobilen Kommunikationsgerät, wie zum Beispiel einem Mobiltelefon oder einem Tablett-Computer darstellen oder eine Batterie mit einem E-Antrieb auf der Unterseite des Reinigungsfahrwagens verbinden.It is also advantageous that the combination of side and partition wall or the combination of two partition walls in the middle of a cleaning trolley with two compartments creates a free space through which, for example, electrical cables can be laid. These wires can connect battery packs and a mobile communication device, such as a cell phone or a tablet computer or connect a battery to an electric drive on the underside of the cleaning trolley.

Generell ist die Beabstandung der Wände vorteilhaft, um zum Beispiel ein Rattern oder Aneinanderschlagen von Seiten- und Trennwand oder Trennwand und Trennwand zu verhindern und mögliche Unebenheiten in den Wänden ausgleichen zu können.In general, the spacing of the walls is advantageous, for example to prevent the side wall and partition wall or partition wall and partition wall from rattling or hitting each other and to be able to compensate for any unevenness in the walls.

In einer Führungsnut eines Stützpfeilers kann eine Seitenwand angeordnet sein, die den Reinigungsfahrwagen nach außen begrenzt. In der anderen Führungsnut des Stützpfeilers kann eine Trennwand angeordnet sein, die im Inneren des Reinigungsfahrwagens angeordnet ist und praktisch die Innenseite der Seitenwand bildet.In a guide groove of a support pillar, a side wall can be arranged, which delimits the cleaning trolley on the outside. A partition wall can be arranged in the other guide groove of the support pillar, which is arranged inside the cleaning trolley and practically forms the inside of the side wall.

Zusätzlich sind die Wände als Seiten-/ Trennwand bzw. im Inneren des Reinigungsfahrwagens als Rücken an Rücken positionierte Trenn-/ Trennwand ausgebildet. Das erlaubt es, den Wänden verschiedene weitere Funktionen zuzuordnen. So kann zum Beispiel die Seitenwand noch weitere Funktionselemente wie Verbindungen für Haken und Halter etc. aufweisen. Wird ein Reinigungsfahrwagen mit zwei Abteilen aufgebaut, so können die sich gegenüber stehenden Trennwände in einem Abteil anders gestaltet sein (zum Beispiel glatt), als die Trennwände in einem anderen Abteil (zum Beispiel mit Führungsschienen zur Aufnahme von Behältern).In addition, the walls are designed as side/partition walls or inside the cleaning trolley as a back-to-back positioned partition/partition wall. This allows various other functions to be assigned to the walls. For example, the side wall can have other functional elements such as connections for hooks and holders, etc. If a cleaning trolley is set up with two compartments, the opposing partition walls in one compartment can be designed differently (e.g. smooth) than the partition walls in another compartment (e.g. with guide rails for holding containers).

Nach einer vorteilhaften Ausgestaltung kann es vorgesehen sein, dass der Quersteg auf seiner dem Längssteg abgewandten Außenseite eine sich im Wesentlichen vertikal und parallel zum Längssteg erstreckende Befestigungsnut aufweist. Hierbei ist von Vorteil, dass die Variabilität des Reinigungsfahrwagens dadurch vergrößert wird.According to an advantageous embodiment, it can be provided that the transverse web has, on its outer side facing away from the longitudinal web, a fastening groove that extends essentially vertically and parallel to the longitudinal web. The advantage here is that the variability of the cleaning trolley is thereby increased.

In der Befestigungsnut kann zumindest ein Befestigungsmittel angeordnet sein. An diesem Befestigungsmittel können Reinigungsutensilien befestigt werden, die durch ihre Befestigung außen am Reinigungsfahrwagen für den Benutzer besonders leicht und schnell zugänglich sind.At least one fastening means can be arranged in the fastening groove. Cleaning utensils can be attached to this attachment means, which are particularly easily and quickly accessible to the user because they are attached to the outside of the cleaning trolley.

Das Befestigungsmittel kann zum Beispiel durch einen hakenförmigen Halter für Reinigungsutensilien gebildet sein. An diesem hakenförmigen Halter können zum Beispiel Reinigungstücher, Schwämme oder Bürsten aufgehängt werden. Auch Behälter mit Putzmittel können mittels des Halters außen am Reinigungsfahrwagen befestigt werden.The fastening means can be formed, for example, by a hook-shaped holder for cleaning utensils. Cleaning cloths, sponges or brushes, for example, can be hung up on this hook-shaped holder. Containers with cleaning agents can also be attached to the outside of the cleaning trolley using the holder.

Nach einer anderen Ausgestaltung kann es vorgesehen sein, dass das Befestigungsmittel durch einen Stielhalter gebildet ist. In einen solchen Stielhalter können Stiele eines Reinigungsgeräts, beispielsweise eines Wischmopps oder eines Flachwischers, eingerastet werden, um das Reinigungsgerät außen am Reinigungswagen einfach, verliersicher und schnell zugänglich transportieren zu können.According to another embodiment, it can be provided that the fastening means is formed by a handle holder. Handles of a cleaning device, for example a mop or a flat mop, can be snapped into such a handle holder in order to be able to transport the cleaning device on the outside of the cleaning trolley in a simple, loss-proof and quickly accessible manner.

Das Befestigungsmittel kann durch einen Anschlag für eine Tür des Reinigungsfahrwagens gebildet sein. Durch einen solchen Anschlag wird verhindert, dass die Tür des Reinigungsfahrwagens unerwünscht hart und laut in ihrer Endposition anschlägt. Der Anschlag kann zum Beispiel durch einen Gummipuffer gebildet sein.The fastening means can be formed by a stop for a door of the cleaning trolley. Such a stop prevents the door of the cleaning trolley from hitting its end position undesirably hard and loudly. The stop can be formed by a rubber buffer, for example.

Um eine Tür in ihrer Offenstellung zu halten, besteht die Möglichkeit, dass das Befestigungsmittel durch einen Magnet für eine Tür des Reinigungsfahrwagens gebildet ist. Die Tür des Reinigungsfahrwagens besteht bei einer solchen Ausführungsform entweder aus einem magnetischen Werkstoff, oder auf der Tür ist ein Magnet angebracht, der mit dem ebenfalls als Magnet ausgebildeten Befestigungsmittel zusammenwirkt und die Tür in Offenstellung hält.In order to keep a door in its open position, there is the possibility that the fastening means is formed by a magnet for a door of the cleaning trolley. In such an embodiment, the door of the cleaning trolley consists either of a magnetic material or a magnet is attached to the door, which interacts with the fastening means, which is also designed as a magnet, and holds the door in the open position.

Um den Reinigungsfahrwagen besser an die jeweiligen Gegebenheiten des Anwendungsfalles anpassen zu können, insbesondere um den Reinigungsfahrwagen bedarfsweise erweitern zu können, kann es vorgesehen sein, dass das Befestigungsmittel durch eine adapterförmige Schnittstelle zu weiteren Anbau-Elementen gebildet ist. Die adapterförmige Schnittstelle kann zum Beispiel als Kupplung für Behälter ausgebildet sein, die mittels der Schnittstelle außen an dem Reinigungsfahrwagen befestigbar sind.In order to be able to better adapt the cleaning carriage to the respective circumstances of the application, in particular to be able to expand the cleaning carriage as required, it can be provided that the fastening means is formed by an adapter-like interface to other add-on elements. The adapter-shaped interface can be designed, for example, as a coupling for containers that can be attached to the outside of the cleaning trolley by means of the interface.

Das Befestigungsmittel ist bevorzugt höhenverstellbar und lösbar in der Befestigungsnut angeordnet. Dadurch ist eine größtmögliche Variabilität gegeben. Das Befestigungsmittel kann dadurch für den Benutzer ergonomisch günstig in der Höhe positioniert werden und bedarfsweise gegen andere Befestigungsmittel einfach ausgetauscht werden.The fastening means is preferably height-adjustable and detachably arranged in the fastening groove. This gives the greatest possible variability. As a result, the fastening means can be ergonomically positioned at a height that is favorable for the user and, if necessary, can be easily exchanged for other fastening means.

Die Stützpfeiler können durch Endlosprofile gebildet sein und aus einem metallischen oder polymeren Werkstoff bestehen.The pillars can be formed by endless profiles and consist of a metallic or polymeric material.

Bestehen die Stützpfeiler aus einem metallischen Werkstoff, gelangen bevorzugt Endlosprofile aus Alu-Strangguss zur Anwendung.If the pillars are made of a metallic material, continuous profiles made of extruded aluminum are preferably used.

Solche Stützpfeiler haben den Vorteil, dass sie einerseits leicht und trotzdem formstabil sind und andererseits in beliebigen Längen abgelängt werden können. Dadurch besteht die Möglichkeit, die Höhe des Reinigungsfahrwagens herstellungsbedingt an die Bedürfnisse des jeweiligen Benutzers anpassen zu können. Die Höhe der Seiten- und/oder Trennwände muss dabei natürlich herstellungsbedingt an die Länge der Stützpfeiler angepasst werden. Zumindest eine der Seitenwände kann eine glatte Außenseite und/oder eine mit Einschubschienen verbundene Innenseite aufweisen. Die Einschubschienen der Innenseite sind dabei bevorzugt derart angeordnet, dass sie mit entsprechend ausgebildeten Einschubschienen der benachbarten Seiten- oder Trennwand eine Führung für tablettförmige Ablagen bilden, die zwischen die Einschubschienen einschiebbar sind. Durch die Einschubschienen kann die Inneneinrichtung des Reinigungsfahrwagens besonders variabel gestaltet werden.Such pillars have the advantage that on the one hand they are light and yet dimensionally stable and on the other hand they can be cut to any length. This makes it possible to adapt the height of the cleaning trolley to the needs of the respective user due to the production process. The height of the side and/or partition walls must of course be adjusted to the length of the pillars due to the manufacturing process. At least one of the side walls can have a smooth outside and/or an inside connected to slide-in rails. The slide-in rails on the inside are preferably arranged in such a way that, together with correspondingly designed slide-in rails on the adjacent side or partition wall, they form a guide for tray-shaped shelves that can be inserted between the slide-in rails. The interior fittings of the cleaning trolley can be designed particularly variably thanks to the slide-in rails.

Gemäß einer vorteilhaften Ausgestaltung kann die Außenseite bedruckbar ausgebildet sein. Der Reinigungsfahrwagen kann dadurch kenntlich gemacht werden. Beispielsweise kann die glatte Außenseite mit einem Aufdruck des Reinigungsfahrwagen-Herstellers versehen sein und/oder mit einer Codierung im weitesten Sinne, um zum Beispiel unterschiedliche Reinigungsfahrwagen desselben Typs unterschiedlichen Benutzern zuordnen zu können.According to an advantageous embodiment, the outside can be designed to be printable. The cleaning trolley can be identified in this way. For example, the smooth outside can be provided with an imprint of the cleaning trolley manufacturer and/or with a coding in the broadest sense, in order to be able to assign different cleaning trolleys of the same type to different users, for example.

Bei größeren Reinigungsfahrwagen, die innen eine Mehrfachunterteilung aufweisen, kann es vorgesehen sein, dass eine Trennwand zwei einander gegenüberliegende Seiten aufweist, die jeweils mit Einschubschienen ausgebildet sind. Die Einschubschienen der einander gegenüberliegenden Seiten können gleich oder voneinander abweichend angeordnet sein. Dabei besteht die Möglichkeit, dass eine Seite der Trennwand mit Einschubschienen feiner unterteilt ist, als die gegenüberliegende. Für manche Anwendungsfälle kann das von Vorteil sein, zum Beispiel dann, wenn bestimmte Bereiche im Inneren des Reinigungsfahrwagens von Ablagen freigehalten werden sollen.In the case of larger cleaning trolleys, which have multiple partitions on the inside, it can be provided that a partition wall has two opposite sides, each of which is designed with slide-in rails. The slide-in rails on the opposite sides can be arranged in the same way or deviating from one another. There is the possibility that one side of the partition is subdivided more finely than the opposite side with slide-in rails. This can be an advantage for some applications, for example if certain areas inside the cleaning trolley are to be kept free of shelves.

Die Grundplatte und/oder die Abdeckplatte oder der obere Rahmen und/oder die Seiten- und/oder Trennwände können aus einem polymeren Werkstoff bestehen. Dadurch weist der Reinigungsfahrwagen insgesamt ein niedriges Gewicht auf, ebenso wie die Einzelteile, aus denen er besteht, so dass Umbauten des Reinigungsfahrwagens zur Anpassung an die jeweiligen Gegebenheiten des Anwendungsfalles vom Benutzer schnell und einfach, insbesondere ohne schwer heben zu müssen, vorgenommen werden können. Bestehen die miteinander zu verbindenden Teile aus einem polymeren Werkstoff, ist deren Formgebung einfach und kostengünstig. Solche Teile können durch die einfache Formgebung leicht konstruktiv so ausgelegt werden, dass Sie werkzeuglos miteinander montierbar sind.The base plate and/or the cover plate or the top frame and/or the side and/or partition walls can be made of a polymeric material. As a result, the cleaning trolley has a low weight overall, as do the individual parts that make it up, so that the cleaning trolley can be modified quickly and easily by the user to adapt it to the particular circumstances of the application, in particular without having to lift anything heavy. If the parts to be connected are made of a polymer material, their shaping is simple and inexpensive. Due to the simple shape, such parts can easily be designed structurally in such a way that they can be assembled together without tools.

Außerdem ist der Reinigungsfahrwagen durch eine solche Werkstoffauswahl korrosionsbeständig und dadurch besonders lange haltbar.In addition, the cleaning trolley is corrosion-resistant thanks to such a choice of materials and is therefore particularly durable.

Die Erfindung betrifft außerdem ein Verfahren zur Montage eines Reinigungsfahrwagens, wie zuvor beschrieben, wobei in einem ersten Montageschritt die Stützpfeiler mittels der jeweiligen Verbindungschuhe auf der Grundplatte werkzeuglos montiert werden, wobei die Grundplatte und die Stützpfeiler nach dem ersten Montageschritt eine vormontierte Einheit bilden, wobei in einem zweiten Montageschritt die Seiten- und/oder Trennwände in die Führungsnuten der Stützpfeiler werkzeuglos montiert werden und wobei in einem dritten Montageschritt die Abdeckplatte oder der obere Rahmen auf die Stützpfeiler der vormontierten Einheit montiert werden.The invention also relates to a method for assembling a cleaning trolley, as described above, wherein in a first assembly step the pillars are assembled without tools by means of the respective connecting shoes on the base plate, the base plate and the pillars forming a preassembled unit after the first assembly step, wherein in in a second assembly step, the side and/or partition walls are assembled in the guide grooves of the pillars without tools, and in a third assembly step, the cover plate or the upper frame are assembled on the pillars of the preassembled unit.

Die werkzeuglose Montage im zweiten Montageschritt erfolgt dadurch, dass die Seiten- und/oder Trennwände von der der Grundplatte abgewandten Seite in die Führungsnuten der Stützpfeiler eingeschoben werden.The tool-free assembly in the second assembly step takes place in that the side and/or partition walls are pushed into the guide grooves of the support pillars from the side facing away from the base plate.

Nach einer vorteilhaften Weiterbildung des Verfahrens kann es vorgesehen sein, dass die Abdeckplatte oder der obere Rahmen im dritten Montageschritt auf die Stützpfeiler der vormontierten Einheit werkzeuglos eingeschnappt werden. Dies kann durch eine Rastverbindung geschehen, die ebenfalls, wie bei der Verbindung zwischen Stützpfeilern und Grundplatte, durch einen Verbindungsschuh erfolgt.According to an advantageous further development of the method, provision can be made for the cover plate or the upper frame to be snapped without tools onto the pillars of the preassembled unit in the third assembly step. This can be done by a snap-in connection, which is also done by a connecting shoe, as is the case with the connection between the support pillars and the base plate.

Alle beim Reinigungsfahrwagen zur Anwendung gelangenden Verbindungsschuhe können als Gleichteile ausgebildet sein. Dadurch ist von Vorteil, dass der Reinigungsfahrwagen insgesamt einfach und kostengünstig herstellbar ist. Bei der Montage ergibt sich der Vorteil, dass durch den Einsatz von Gleichteilen keine Verwechslungsgefahr der jeweiligen Teile beim Zusammenbau des Reinigungsfahrwagens besteht.All connecting shoes used in the cleaning trolley can be designed as identical parts. This has the advantage that the cleaning trolley can be produced simply and inexpensively overall. During assembly, there is the advantage that the use of identical parts means that there is no risk of confusing the respective parts when assembling the cleaning trolley.

Auch die Lagerhaltung von Ersatzteilen, wie beispielsweise des Verbindungsschuhs, wird dadurch vereinfacht.This also simplifies the storage of spare parts, such as the connecting shoe.

Ausführung der Erfindungimplementation of the invention

In Figur 1 ist ein Ausführungsbeispiel des erfindungsgemäßen Reinigungsfahrwagens in perspektivischer Darstellung gezeigt.In figure 1 an embodiment of the cleaning trolley according to the invention is shown in a perspective view.

Der Reinigungsfahrwagen umfasst eine Grundplatte 1, an deren Unterseite 27 Räder 28 angeordnet sind. Die Grundplatte 1 ist rechteckig gestaltet, und die Räder 28 sind an den jeweiligen Ecken der Unterseite 27 montiert.The cleaning trolley includes a base plate 1, on the underside 27 wheels 28 are arranged. The base plate 1 is rectangular in shape, and the wheels 28 are mounted on the bottom 27 at the respective corners.

Auf der Oberseite 29 der Grundplatte 1 sind im gezeigten Ausführungsbeispiel in Fahrtrichtung 30 einander gegenüberliegend zwei Seitenwände 4 angeordnet, die die Außenseite und äußere Begrenzung des Reinigungsfahrwagens bilden.On the upper side 29 of the base plate 1, two side walls 4 are arranged opposite one another in the direction of travel 30 in the exemplary embodiment shown, which form the outside and outer boundary of the cleaning trolley.

In Fahrtrichtung 30 zwischen den Seitenwänden 4 sind Trennwände 5 angeordnet ist. Durch die Trennwände 5 wird der Innenraum 31 des Reinigungsfahrwagens in zwei Teilräume 32, 33 unterteilt, wobei in diesem Ausführungsbeispiel der eine Teilraum 33 durch eine Tür 34 verschließbar ist.Partition walls 5 are arranged between the side walls 4 in the direction of travel 30 . The interior space 31 of the cleaning vehicle is divided by the partition walls 5 into two sub-spaces 32, 33, one sub-space 33 being closable by a door 34 in this exemplary embodiment.

Auf der der Grundplatte 1 abgewandten Seite der Seitenwände und der Trennwände 5 ist der obere Rahmen 3 angeordnet, der die Seitenwände 4 und die Trennwände 5 in ihre Position hält. Anstelle des Rahmens 3 kann, wie in Figur 1 ebenfalls dargestellt, alternativ eine Abdeckplatte 2 als oberer Abschluss des Reinigungsfahrwagens zur Anwendung gelangen.On the side of the side walls and the partition walls 5 facing away from the base plate 1, the upper frame 3 is arranged, which holds the side walls 4 and the partition walls 5 in their position. Instead of frame 3, as in figure 1 also shown, alternatively a cover plate 2 can be used as the upper end of the cleaning trolley.

Die Grundplatte 1, der Rahmen 3 oder die Abdeckplatte 2 sowie die in vertikaler Richtung 6 dazwischen angeordneten Seiten- 4 und/oder Trennwände 5 sind durch das Stecksystem 7 miteinander verbunden, wobei das Stecksystem 7 separat erzeugte Stützpfeiler 8 umfasst und wobei die Stützpfeiler 8 mit der Grundplatte 1 und der Abdeckplatte 2 oder dem oberen Rahmen 3 kraft- und/oder formschlüssig verbunden sind. Die genannten Teile sind lediglich gesteckt, dadurch werkzeuglos miteinander montierbar und können bedarfsweise, ebenfalls werkzeuglos, zerstörungsfrei voneinander getrennt oder baulich verändert werden.The base plate 1, the frame 3 or the cover plate 2 and the side walls 4 and/or partitions 5 arranged between them in the vertical direction 6 are connected to one another by the plug-in system 7, with the plug-in system 7 comprising separately produced pillars 8 and with the pillars 8 having the base plate 1 and the cover plate 2 or the upper frame 3 are non-positively and/or positively connected. The parts mentioned are simply plugged in, so they can be assembled together without tools and can be separated from one another or structurally modified if necessary, also without tools, non-destructively.

In Figur 2 ist ein Stützpfeiler 8 in einer perspektivischen Ansicht, beispielhaft für alle Stützpfeiler 8, von oben gezeigt. Wie zu erkennen ist, ist der Stützpfeiler 8 im Wesentlichen T-förmig ausgebildet und umfasst einen ins Innere 12 des Reinigungsfahrwagens gerichteten Längssteg 13, der dem Quersteg 14 im Wesentlichen mittig zugeordnet ist. Der Stützpfeiler 8 ist durch ein Endlosprofil gebildet, das als Meterware hergestellt und passend abgelängt ist. Generell kann das Endlosprofil aus einem metallischen oder einem polymeren Werkstoff bestehen.In figure 2 a pillar 8 is shown in a perspective view, exemplary for all pillars 8, from above. As can be seen, the support pillar 8 is essentially T-shaped and comprises a longitudinal web 13 which is directed towards the interior 12 of the cleaning trolley and which is assigned to the transverse web 14 essentially in the middle. The pillar 8 is formed by an endless profile that is manufactured by the meter and cut to length. In general, the endless profile can consist of a metallic or a polymeric material.

Die hier dargestellten Endlosprofile sind durch Alu-Strangguss Profile gebildet.The endless profiles shown here are made of extruded aluminum profiles.

In Fahrtrichtung 30 beiderseits des Längsstegs 13 weist der Quersteg 14 jeweils eine Führungsnut 9, 10 zur Aufnahme einer Seiten- 4 und/oder einer Trennwand 5 auf. Die Seiten- 4 und/oder Trennwand 5 sind randseitig von der Führungsnut 9, 10 umklammert.On both sides of the longitudinal web 13 in the direction of travel 30 , the transverse web 14 has a guide groove 9 , 10 for receiving a side wall 4 and/or a partition wall 5 . The side wall 4 and/or partition wall 5 are clamped around the edge by the guide groove 9, 10.

Die zur Anwendung gelangenden Seitenwände 4 haben jeweils eine glatte Außenseite 21.

Die genannten Befestigungsmittel sind höhenverstellbar und lösbar in der Befestigungsnut 16 angeordnet, wobei, in Abhängigkeit von den jeweiligen Gegebenheiten des Anwendungsfalles, auch mehrere Befestigungsmittel der gleichen oder von unterschiedlicher Art zur Anwendung gelangen können.The fastening means mentioned are height-adjustable and releasably arranged in the fastening groove 16, it also being possible for several fastening means of the same or different type to be used, depending on the respective circumstances of the application.

In Figur 4 ist eine Draufsicht auf den Reinigungsfahrwagen aus Figur 1 gezeigt. In dem gezeigten Abschnitt ist der im Verbindungsschuh 18 angeordnete Stützpfeiler 8 gezeigt, wobei der Verbindungsschuh 18 und die Grundplatte 1 durch eine Rastverbindung, umfassend eine Rastnase 19 und eine Hinterschneidung 20, miteinander verbunden sind.In figure 4 12 is a plan view of the cleaning trolley figure 1 shown. The section shown shows the support pillar 8 arranged in the connecting shoe 18 , the connecting shoe 18 and the base plate 1 being connected to one another by a latching connection comprising a latching lug 19 and an undercut 20 .

Gezeigt ist eine Seitenwand 4, die eine glatte Außenseite 21 hat und in der Führungsnut 10 des Stützpfeilers 8 angeordnet ist.A side wall 4 is shown, which has a smooth outer side 21 and is arranged in the guide groove 10 of the pillar 8 .

Die Trennwand 5 ist in der Führungsnut 9 des Stützpfeilers 8 angeordnet und weist einerseits Einschubschienen 22 auf.The partition wall 5 is arranged in the guide groove 9 of the support pillar 8 and has slide-in rails 22 on one side.

In Figur 5 ist der Reinigungsfahrwagen aus Figur 1 in einer perspektivischen Draufsicht von schräg oben gezeigt, ohne Abdeckplatte 2 oder ohne oberen Rahmen 3.In figure 5 the cleaning trolley is off figure 1 shown in a perspective top view obliquely from above, without cover plate 2 or without upper frame 3.

Die Montage des Reinigungsfahrwagens erfolgt derart, dass in einem ersten Montageschritt die Stützpfeiler 8 mittels der jeweiligen Verbindungsschuhe 18 auf der Grundplatte 1 werkzeuglos montiert werden. Die Grundplatte 1 und die Stützpfeiler 8 bilden nach dem ersten Montageschritt die vormontierte Einheit 26.The cleaning trolley is assembled in such a way that, in a first assembly step, the support pillars 8 are assembled on the base plate 1 without tools by means of the respective connecting shoes 18 . After the first assembly step, the base plate 1 and the pillars 8 form the preassembled unit 26.

In einem zweiten Montageschritt werden die Seiten- 4 und die zumindest eine Trennwände 5 in die Führungsnuten 9, 10 der jeweiligen Stützpfeiler 8 werkzeuglos montiert.In a second assembly step, the side walls 4 and the at least one partition 5 are mounted in the guide grooves 9, 10 of the respective pillars 8 without tools.

Dann sieht der Reinigungsfahrwagen wie in Figur 5 dargestellt aus.Then the cleaning trolley looks like in figure 5 shown off.

In einem dritten Montageschritt wird die Abdeckplatte 2 oder der obere Rahmen 3 auf die Stützpfeiler 8 der vormontierten Einheit 26 montiert, wobei im gezeigten Ausführungsbeispiel auch für diese Verbindung Verbindungsschuhe 18 zur Anwendung gelangen, entsprechend den Verbindungsschuhen 18, die die Stützpfeiler 8 und die Grundplatte 1 verbinden.In a third assembly step, the cover plate 2 or the upper frame 3 is mounted on the pillars 8 of the preassembled unit 26, whereby in the exemplary embodiment shown, connection shoes 18 are also used for this connection, corresponding to the connection shoes 18 that connect the pillars 8 and the base plate 1 connect.

In Figur 6 ist ein L-förmig ausgebildeter Stützpfeiler 8 gezeigt. Die Stützpfeiler (8) sind, in einer Draufsicht betrachtet, im Wesentlichen L-förmig ausgebildet. Sie umfassen einen ins Innere (12) des Reinigungsfahrwagens gerichteten Längssteg (13) und einen Quersteg (14). Das freie Ende des Querstegs (14) weist eine Führungsnut (9) zur Aufnahme einer Seiten- (4) und/oder Trennwand (5) auf.In figure 6 an L-shaped support pillar 8 is shown. The pillars (8) are essentially L-shaped when viewed from above. They comprise a longitudinal web (13) directed towards the interior (12) of the cleaning trolley and a transverse web (14). The free end of the transverse web (14) has a guide groove (9) for receiving a side (4) and/or partition (5).

Im hier gezeigten Ausführungsbeispiel des erfindungsgemäßen Reinigungsfahrwagens bestehen die Stützpfeiler 8 aus extrudierten Alu-Profilen, die nur durch das Einbringen einfacher Querbohrungen an den jeweiligen Enden nachbearbeitet werden. Die Stützpfeiler 8 werden per Klemmung und Einschnappen (Schnapphaken am Verbindungschuh 18 greifen in die Querbohrungen der Stützpfeiler 8) in die aus einem polymeren Werkstoff bestehenden Verbindungsschuhe 18 gesteckt und verschnappt. Die Stützpfeiler 8 werden mit ihren Verbindungschuhen 18 in die aus einem polymeren Werkstoff bestehende Grundplatte 1 gesteckt. Dabei wird einerseits der relativ dünnwandige Verbindungschuh 18 nochmals geklemmt. Zudem weist der Verbindungsschuh 18 einen weiteren Schnapphaken auf, der mit der Grundplatte 1 und der Abdeckplatte 2 oder dem oberen Rahmen 3 einrastet und einen Form- und Kraftschluss herstellt. Der Vorteil ist, dass die Verbindungsschuhe 18 kleine Kunststoffteile sind, die einfach derart angepasst werden können, dass der Spalt zwischen Stützpfeiler 8 und Verbindungsschuh 18, bzw. zwischen Verbindungsschuh 18 und Grundplatte 1 minimiert wird. Das sorgt für eine ordentliche Klemmung.In the exemplary embodiment of the cleaning trolley according to the invention shown here, the pillars 8 consist of extruded aluminum profiles, which are only reworked by introducing simple cross-holes at the respective ends. The pillars 8 are inserted and snapped into the connecting shoes 18 made of a polymer material by clamping and snapping (snapping hooks on the connecting shoe 18 engage in the transverse bores of the pillars 8). The pillars 8 are inserted with their connecting shoes 18 into the base plate 1, which is made of a polymer material. On the one hand, the relatively thin-walled connecting shoe 18 is clamped again. In addition, the connecting shoe 18 has a further snap hook, which engages with the base plate 1 and the cover plate 2 or the upper frame 3 and creates a positive and non-positive connection. The advantage is that the connecting shoes 18 are small plastic parts that can easily be adjusted in such a way that the gap between the support pillar 8 and the connecting shoe 18, or between the connecting shoe 18 and the base plate 1, is minimized. This ensures proper clamping.

Der Reinigungsfahrwagen ist per se beladen, d.h. alle Verbindungsschuhe zwischen der Grundplatte 1 und den Stützpfeilern 18 sind auf Druck beansprucht. Nur bei Zug durch den Benutzer kann zuerst der Stützpfeiler 8 mit dem Verbindungsschuh durch Lösen der Schnappverbindung Verbindungsschuh 18/Grundplatte 1 gelöst werden. Danach, soweit notwendig, kann der Verbindungschuh 18 vom jeweiligen Stützpfeiler 8 abgenommen werden. Dazu wird die Verbindung zunächst entriegelt. Dann können Verbindungschuh 18 und Stützpfeiler 8 voneinander getrennt werden.The cleaning trolley is loaded per se, i.e. all connecting shoes between the base plate 1 and the support pillars 18 are subjected to pressure. Only when the user pulls can the support pillar 8 with the connecting shoe be released first by releasing the snap connection connecting shoe 18/base plate 1. Thereafter, if necessary, the connecting shoe 18 can be removed from the respective support pillar 8. To do this, the connection is first unlocked. Then connecting shoe 18 and pillar 8 can be separated from each other.

Der Zusammenbau erfolgt in umgekehrter Reihenfolge. Zuerst wird der Verbindungschuh18 auf den Stützpfeiler 8 aufgesteckt, bis er einklickt, dann wird der Stützpfeiler 8 zusammen mit dem Verbindungschuh 18 in die Grundplatte 1 gedrückt, bis er einklickt.The assembly is done in reverse order. First, the connecting shoe 18 is slipped onto the pillar 8 until it clicks, then the pillar 8 is pressed together with the connecting shoe 18 into the base plate 1 until it clicks.

Generell besteht die Möglichkeit, die Verbindungschuhe 18 mit den Stützpfeilern 8 durch eine Klemmung zu verbinden, ebenso wie die Verbindungsschuhe 18 und die Grundplatte 1.In general, it is possible to connect the connecting shoes 18 to the pillars 8 by clamping, as well as the connecting shoes 18 and the base plate 1.

Nach einer anderen Ausgestaltung können die Verbindungschuhe 18 und die Stützpfeiler 8 durch eine Klemmung verbunden werden. Die Verbindungschuhe 18 und die Grundplatte 1 können demgegenüber geklemmt und verrastet sein. Alternativ kann es vorgesehen sein, dass die Verbindungschuhe 18 und die Stützpfeiler 8 geklemmt und verrastet sind, die Verbindungschuhe 18 und die Grundplatte 1 demgegenüber nur geklemmt.According to another embodiment, the connecting shoes 18 and the pillars 8 can be connected by clamping. In contrast, the connecting shoes 18 and the base plate 1 can be clamped and latched. Alternatively, it can be provided that the connecting shoes 18 and the pillars 8 are clamped and latched, while the connecting shoes 18 and the base plate 1 are only clamped.

Im hier gezeigten Ausführungsbeispiel sind die Verbindungschuhe 18 und die Stützpfeiler 8 geklemmt und verrastet, ebenso wie die Verbindungschuhe 18 und die Grundplatte 1.In the embodiment shown here, the connecting shoes 18 and the support pillars 8 are clamped and latched, as are the connecting shoes 18 and the base plate 1.
