Description

Die Erfindung betrifft eine Vorrichtung zum Entfernen von auf ebenen Flächen verlegten Belägen mit einem Tragrahmen zur Lagerung von Antriebsrädern sowie zur Aufnahme eines Motors und eines Getriebes zum Antrieb der Antriebsräder und mit einem motorisch angetriebenen Trennmesser.The invention relates to a device for removing deposits laid on flat surfaces with a support frame for supporting drive wheels and for receiving a motor and a transmission for driving the drive wheels and with a motor-driven cutting knife.

Auf ebenen Flächen verlegte Beläge, wie bspw. auf Fußböden verlegte Teppichbeläge, werden im verlegten Zustand mit ihrer Auflagefläche verklebt. Damit wird ein Verrutschen und Verschieben der Beläge beim Befahren oder Begehen derselben verhindert. Sollen derartige Beläge infolge Abnutzung oder Beschädigung durch neue Beläge ersetzt werden, müssen zunächst die alten Beläge entfernt werden.Floor coverings laid on flat surfaces, such as carpets laid on floors, are glued to their support surface when installed. This prevents slipping and shifting of the coverings when driving on or passing through them. If such coverings are to be replaced by new coverings as a result of wear or damage, the old coverings must first be removed.

Es sind bereits Vorrichtungen bekannt, mit denen ein stückweises oder bahnweises Entfernen derartiger alter Beläge möglich ist. Dabei wird ein motorisch angetriebenes schwingendes Trennmesser zwischen der Belag und der ebenen Auflagefläche gestoßen. Diese bekannten Vorrichtungen sind sehr klobig und sind vom Benutzer nur unter großem Kraftaufwand und mühsam zu handhaben.There are already known devices with which a piecewise or web-wise removal of such old coverings is possible. In this case, a motor-driven oscillating separating knife is pushed between the covering and the flat bearing surface. These known devices are very clunky and are the user only with great effort and laborious to handle.

Aus der deutschen Gebrauchsmusterschrift DE 76 18 703.6 ist eine solche Vorrichtung zum Entfernen von Bodenbelägen bekannt. Auf einem Gestell mit einem Handgriff zum Vorwärtsbewegen der Vorrichtung sind ein Motor und ein Getriebe zum Antreiben des Trennmessers angeordnet. Gegenüber dem Trennmesser sind zwei Führungsräder vorgesehen, die die Führung und das Vorwärtsbewegen der Vorrichtung beim Entfernen eines Bodenbelags erleichtern.From the German Utility Model DE 76 18 703.6 Such a device for removing floor coverings is known. On a rack with a handle for advancing the apparatus, a motor and a gear for driving the separating blade are arranged. Opposite the cutting knife two guide wheels are provided, which facilitate the guidance and the forward movement of the device when removing a floor covering.

Die US 4,880,491 A beschreibt eine Vorrichtung, welche ausgebildet ist, einen Dachbelag von einem Dach zu entfernen.The US 4,880,491 A describes a device which is designed to remove a roof covering from a roof.

Die US 6,135,566 A beschreibt eine Vorrichtung zum Anheben eines Bodenbelags. Die Vorrichtung weist Stahlplatten auf, welche an einem Gehäuse befestigt sind. Ferner weist diese Vorrichtung Antriebsräder zum Antreiben der Vorrichtung und Räder auf, welche lose drehbar sind, und parallel zu den Antriebsrädern und in Antriebsrichtung hinter den Antriebsrädern angeordnet sind. Des Weiteren weist diese Vorrichtung ein motorisch angetriebenes Trennmesser auf.The US 6,135,566 A describes a device for lifting a floor covering. The device has steel plates which are fixed to a housing. Furthermore, this device has drive wheels for driving the device and wheels, which are loosely rotatable, and parallel to the drive wheels and in the drive direction behind the Drive wheels are arranged. Furthermore, this device has a motor-driven separating knife.

In der US-Patentschrift 4,394,052 ist eine Vorrichtung zum Abheben eines Bodenbelags beschrieben, bei der auf einem Rahmen ein Elektromotor und ein Hydraulikzylinder zum Antrieb eines Trennmessers und einer Einrichtung zum Aufwickeln des abgehobenen Bodenbelags vorgesehen sind. Diese Vorrichtung ist sehr klobig aufgebaut und sehr schwerfällig in der Bedienung.
Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung zu schaffen, die einfach und übersichtlich aufgebaut ist und eine kraftsparende und bequeme Handhabung ermöglicht.In the U.S. Patent 4,394,052 a device for lifting a floor covering is described in which a frame on an electric motor and a hydraulic cylinder for driving a cutting knife and means for winding the lifted flooring are provided. This device is very clunky and very cumbersome to use.
The invention has for its object to provide a generic device that is simple and clear and allows a power-saving and convenient handling.

Dies wird erfindungsgemäß mit einer Vorrichtung mit den Merkmalen des Patentanspruchs 1 erreicht. Die Erfindung zeichnet sich dadurch aus, daß am Tragrahmen mindestens ein lose drehbares Stützelement parallel zu den Antriebsrädern angeordnet ist.This is achieved according to the invention with a device having the features of patent claim 1. The invention is characterized in that at least one loose rotatable support member is arranged parallel to the drive wheels on the support frame.

Diese Maßnahme hat den großen Vorteil, daß am Ende eines abgelösten Stückes oder einer abgelösten Bahn eines Belags die Vorrichtung durch Kippen derselben auf das auf die Auflagefläche gedrückte, lose drehbare Stützelement abgestützt werden kann. Dadurch werden die Antriebsräder von der Auflagefläche abgehoben. Das hat zur Folge, daß das Zurückbewegen der Vorrichtung zur neuen Einsatzstelle leicht und mühelos bewerkstelligt werden kann, weil die Antriebsräder die Auflagefläche nicht mehr berühren und ein Vorwärtsbewegen der Vorrichtung unterbunden ist. Die Antriebsräder können sich beim Zurückbewegen der Vorrichtung entweder weiterdrehen - das heißt, sie müssen in ihrer Drehrichtung nicht umgeschaltet werden, was die elektrische Einrichtung der Vorrichtung schont und vereinfacht - oder ihr Antrieb kann während des Zurückbewegens der Vorrichtung mittels eines geeigneten Ein- und Ausschalters abgeschaltet sein. Beim Kippen der Vorrichtung zurück in ihre Betriebslage kommen die Antriebsräder wieder mit der Auflagefläche in Kontakt und treiben die Vorrichtung erneut vorwärts.This measure has the great advantage that at the end of a detached piece or a detached track of a covering, the device by tilting the same can be supported on the pressed on the support surface, loosely rotatable support member. As a result, the drive wheels are lifted from the support surface. This has the consequence that the moving back of the device to the new site can be easily and effortlessly accomplished because the drive wheels no longer touch the support surface and a forward movement of the device is prevented. The drive wheels may either continue to rotate upon retraction of the device - that is, they need not be reversed in their direction of rotation, which conserves and simplifies the electrical device of the device - or their drive may be turned off during the return movement of the device by means of a suitable on / off switch be. When tilting the device back to its operating position, the drive wheels come back into contact with the support surface and drive the device forward again.

Erfindungsgemäß ist im Bereich der Antriebsräder je eine Stützplatte vorgesehen. Jede Stützplatte weist mindestens zwei mit gleichem Abstand zur Mitte der Achse der Antriebsräder angeordnete Bolzen auf, die in im Tragrahmen ausgebildete kreissegmentförmige Langlöcher eingreifen.According to the invention, a support plate is provided in the region of the drive wheels. Each support plate has at least two equidistant from the center of the axis of the Drive wheels arranged bolts, which engage in formed in the support frame circular segment-shaped slots.

Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous developments of the invention will become apparent from the dependent claims.

Das Stützelement ist in Richtung der Vorwärtsbewegung der Vorrichtung hinter den Antriebsrädern angeordnet. Dabei kann es als eine einzelne breite Stützrolle gestaltet sein, die mittig zu den Antriebsrädern angeordnet ist. Als eine Alternative bietet sich an, das Stützelement in Form von mindestens zwei Stützrädern auszubilden . Eine breite Stützrolle bzw. mit Abstand zueinander angeordnete Stützräder geben der Vorrichtung eine sichere Stabilität, wenn die Vorrichtung zum Abheben der Antriebsräder und des Trennmessers auf die Stützrolle oder die Stützräder gekippt wird.The support element is arranged in the direction of forward movement of the device behind the drive wheels. It can be designed as a single wide support roller, which is arranged centrally to the drive wheels. As an alternative, it is advisable to form the support element in the form of at least two support wheels. A wide support roller or spaced apart support wheels give the device a secure stability when the device for lifting the drive wheels and the separating knife is tilted onto the support roller or the support wheels.

Zum Kippen der Vorrichtung ist es von Vorteil, wenn am oberen Ende des Tragrahmens oberhalb des Stützelements mindestens ein Führungsgriff vorgesehen ist.For tilting the device, it is advantageous if at least one guide handle is provided at the upper end of the support frame above the support element.

Der Gesamtaufbau der Vorrichtung kann so getroffen sein, daß der Tragrahmen aus zwei mit Abstand zueinander liegenden Schenkeln, vorzugsweise gleicher Form und Größe, gebildet ist, wobei die Schenkel an ihrem oberen Ende zu einem Führungsgriff zusammenlaufen können. Am anderen Ende der Schenkel sind in einer bevorzugten Ausführungsform die Antriebsräder gelagert.The overall structure of the device may be such that the support frame of two spaced legs, preferably the same shape and size, is formed, wherein the legs can converge at its upper end to form a guide handle. At the other end of the legs, the drive wheels are mounted in a preferred embodiment.

Oberhalb der Antriebsräder können am Tragrahmen, bspw. zwischen den den Tragrahmen bildenden Schenkeln, der Antriebsmotor und das Getriebe für den Antrieb der Antriebsräder untergebracht sein. Die Anordnung der einzelnen Bauteile kann so getroffen sein, daß das Getriebe unmittelbar oberhalb der Antriebsräder angeordnet ist.Above the drive wheels can be housed on the support frame, for example. Between the support frame forming legs, the drive motor and the transmission for driving the drive wheels. The arrangement of the individual components can be made so that the transmission is arranged directly above the drive wheels.

In der Zeichnung ist ein Ausführungsbeispiel einer Vorrichtung 10 zum Abheben von Belägen von ebenen Flächen, insbesondere von Bodenbelägen von Fußböden, dargestellt. Die Vorrichtung 10 weist einen Tragrahmen 11 auf, der durch zwei parallel und mit Abstand zueinander liegende Schenkel 12, 13 gleicher Form und Größe gebildet ist. Die Schenkel 12 und 13 laufen in ihrem oberen Ende zu einem Führungsgriff 14 zusammen, an dem die Vorrichtung 10 während ihres Betriebs gehalten und geführt wird. Am unteren Ende der Schenkel 12, 13 sind um eine in denselben vorgesehene Achse 15 Antriebsräder 16 gelagert, die die Vorrichtung 10 zum Abheben eines Belags in eine Vorwärtsbewegung treiben.In the drawing, an embodiment of a device 10 for lifting pads of flat surfaces, in particular of floor coverings, is shown. The device 10 has a support frame 11, which is formed by two parallel and spaced apart legs 12, 13 of the same shape and size. The legs 12 and 13 converge in their upper end to a guide handle 14, on which the device 10 is held and guided during its operation. At the lower end of the legs 12, 13 15 drive wheels 16 are mounted about an axis provided in the same, which drive the device 10 for lifting a lining in a forward movement.

Zum Antrieb der Antriebsräder 16 sind ein Motor 17 sowie ein Getriebe 18 vorgesehen, wobei das den Motor 17 tragende Getriebe 18 über eine zu beiden Seiten desselben angeordnete Stützplatte 19 mit den Schenkeln 12, 13 fest verbunden ist.To drive the drive wheels 16, a motor 17 and a gear 18 are provided, wherein the gear 17 carrying the motor 18 via a on both sides of the same arranged support plate 19 with the legs 12, 13 is fixedly connected.

In Vorwärtsbewegung der Vorrichtung 10 gesehen sind hinter den Antriebsrädern 16 an einem an den Schenkeln 12, 13 ausgebildeten Auslegerarm 22 zwei als Stützelement wirkende und um eine Achse 20 lose drehbare Stützräder 21 vorgesehen. Die Aufgabe und Wirkung dieser Stützräder wird weiter unten beschrieben.Seen in forward movement of the device 10 are behind the drive wheels 16 on a formed on the legs 12, 13 boom 22 two as a support element acting and about an axis 20 loosely rotatable support wheels 21 are provided. The task and effect of these support wheels will be described below.

Ferner sind beim Ausführungsbeispiel an der Stützplatte 19 vier zentrisch und mit gleichem Winkelabstand um die Achse 15 angeordnete Bolzen 23 angebracht, die in korrespondierende, in den Schenkeln 12, 13 eingearbeitet kreissegmentförmige Langlöcher 24 eingreifen. Auf der den Stützrädern 21 gegenüberliegenden Seite der Achse 15 ist ein Trennmesser 25 mittels einer Grundplatte 27 an der Stützplatte 19 mittels Schrauben 26 gelenkig befestigt. Auf der Stützplatte 19 ist ein Antriebsmotor 28 für das Trennmesser 25 angeordnet, der letzteres in eine stoßartige Schwingbewegung zum Abheben des Belages versetzt.Further, in the embodiment of the support plate 19 four centrally arranged and at the same angular distance about the axis 15 arranged bolts 23 which engage in corresponding, incorporated in the legs 12, 13 circular segment long slots 24. On the support wheels 21 opposite side of the axis 15, a separating knife 25 is fixed by means of a base plate 27 to the support plate 19 by means of screws 26 hinged. On the support plate 19, a drive motor 28 is arranged for the cutting blade 25, the latter is set in a jerky swinging movement for lifting the lining.

Wie bei dem in der Zeichnung dargestellten Ausführungsbeispiel erkennbar, sitzen in der Arbeitsstellung der Vorrichtung 10 die beiden Antriebsräder 16 auf der Auflagefläche 30 auf und treiben aufgrund der Bodenreibung die Vorrichtung 10 vorwärts, um einen Belag von der Auflagefläche 30 abzuheben. Das Trennmesser 25 liegt dabei mit seiner Schneide auf der Auflagefläche 30 auf, so daß es zwischen dem Belag und der Auflagefläche 30 arbeiten kann. In dieser Arbeitsstellung hängen die Stützräder 21 oberhalb der Auflagefläche 30 in der Luft.As can be seen in the embodiment shown in the drawing, sit in the working position of the device 10, the two drive wheels 16 on the support surface 30 and drive due to the bottom friction, the device 10 forward to lift a coating from the support surface 30. The cutting knife 25 rests with its cutting edge on the bearing surface 30, so that it can work between the lining and the bearing surface 30. In this working position, the support wheels 21 hang above the support surface 30 in the air.

Nach dem Abheben eines Stücks oder einer Bahn des Belages muss die Vorrichtung 10 zu einer neuen Einsatzstelle zurückbewegt werden. Deshalb kann die Vorrichtung 10 vor dem Zurückbewegen durch eine Kippbewegung in Richtung des Pfeils D auf die Stützräder 21 gestellt werden, wodurch die Antriebsräder 16 von der Auflagefläche 30 abgehoben werden (vgl. Figuren 3 und 4). Bei diesem Vorgang laufen die Bolzen 23 gegen ein Ende der Langlöcher 24, so daß die Antriebsräder 16 und das Trennmesser 25 in den Schenkeln 12, 13 hängen. Nun kann in einer bequemen Rückwärtsbewegung die Vorrichtung 10 an die neue Einsatzstelle zurück gezogen werden. Dabei können der Motor 17 und auch der Antriebsmotor 28 weiterlaufen, ohne daß dies die Zurückbewegung der Vorrichtung 10 stört.After lifting a piece or track of the pad, the device 10 must be moved back to a new site. Therefore, the device 10 can be placed on the support wheels 21 before moving back by a tilting movement in the direction of arrow D, whereby the drive wheels 16 are lifted from the support surface 30 (see. FIGS. 3 and 4 ). In this process, the bolts 23 run against one end of the slots 24 so that the drive wheels 16 and the cutting blade 25 in the legs 12, 13 hang. Now in a convenient backward movement, the device 10 can be pulled back to the new site. In this case, the motor 17 and also the drive motor 28 continue to run without this interfering with the return movement of the device 10.
