Description

Vorrichtung zum Entfernen von auf ebenen Flächen verlegten BelägenDevice for removing coverings laid on flat surfaces
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 coverings laid on flat surfaces with a support frame for mounting 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.Coverings laid on flat surfaces, such as carpet coverings laid on floors, are glued to their contact surface when laid. This prevents the pads from slipping and shifting when driving or walking on them. If such coverings are to be replaced by new coverings due to 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.Devices are already known with which piece-by-piece or sheet-by-piece removal of such old coverings is possible. A motor-driven vibrating cutting knife is pushed between the covering and the flat contact surface. These known devices are very bulky and can only be handled with great effort and labor by the user.
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.Such a device for removing floor coverings is known from German utility model DE 76 18 703.6. A motor and a gear for driving the cutting knife are arranged on a frame with a handle for moving the device forward. Two guide wheels are provided opposite the separating knife, which make it easier to guide and move the device forward when removing a floor covering.
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 Trermmessers 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.US Pat. No. 4,394,052 describes a device for lifting off a floor covering, in which an electric motor and a hydraulic cylinder for driving a tremometer and a device for winding up the raised floor covering are provided on a frame. This device is very bulky and very cumbersome to use. The invention has for its object to provide a generic device that is simple and clear and allows energy-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 with the features of claim 1. The invention is characterized in that at least one loosely rotatable support element 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 dieThis measure has the great advantage that at the end of a detached piece or a detached web of a covering, the device by tilting it onto the

Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous developments of the invention result from the subclaims.
Im einzelnen kann das Stützelement in Richtung der Vorwärtsbewegung der Vorrichtung hinter den Antriebsrädern angeordnet sein. 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 und sie ggf. im Bereich hinter den Antriebsrädern anzuordnen. 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. Zum Kippen der Vorrichtung ist es von Vorteil, wenn am oberen Ende des Tragrahmens oberhalb des Stützelements mindestens ein Führungsgriff vorgesehen ist.In particular, the support element can be arranged behind the drive wheels in the direction of the forward movement of the device. It can be designed as a single wide support roller, which is arranged centrally to the drive wheels. An alternative is to design the support element in the form of at least two support wheels and, if necessary, to arrange it in the area behind the drive wheels. A wide support roller or support wheels arranged at a distance from one another give the device secure stability when the device for lifting the drive wheels and the cutting knife is tilted onto the support roller or the support wheels. 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 can be such that the supporting frame is formed from two legs spaced apart from one another, preferably of the same shape and size, the legs being able to converge at their upper end to form a guide handle. In a preferred embodiment, the drive wheels are mounted at the other end of the legs.
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, the drive motor and the gear for driving the drive wheels can be accommodated on the support frame, for example between the legs forming the support frame. The arrangement of the individual components can be such that the transmission is arranged directly above the drive wheels.
Eine bevorzugte Weiterbildung sieht vor, daß im Bereich der Antriebsräder je eine Stützplatte vorgesehen ist. Jede Stützplatte weist mindestens zwei mit gleichem Abstand zur Mitte der Achse der Antriebsräder angeordnete Bolzen auf, die in im Tragrahmen ausgebildete kreissegmentformige Langlöcher eingreifen.A preferred further development provides that a support plate is provided in the area of the drive wheels. Each support plate has at least two bolts which are arranged at the same distance from the center of the axis of the drive wheels and which engage in elongated holes in the form of circular segments in the support frame.

In der Zeichnung ist ein Ausfuhrungsbeispiel 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 exemplary embodiment of a device 10 for lifting coverings from flat surfaces, in particular floor coverings from floors, is shown. The device 10 has a support frame 11, which is formed by two parallel and spaced legs 12, 13 of the same shape and size. The legs 12 and 13 converge in their upper end to form 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, drive wheels 16 are mounted about an axis 15 provided therein, which drive the device 10 for lifting off a covering 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.A motor 17 and a gear 18 are provided for driving the drive wheels 16, the gear 18 carrying the motor 17 being firmly connected to the legs 12, 13 via a support plate 19 arranged on both sides thereof.
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 the forward movement of the device 10, two support wheels 21, which act as a support element and can be rotated loosely about an axis 20, are provided behind the drive wheels 16 on an extension arm 22 formed on the legs 12, 13. The task and effect of these support wheels is described below.
Ferner sind beim Ausfuhrungsbeispiel 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 kreissegmentformige 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.Furthermore, in the exemplary embodiment, four bolts 23 are arranged on the support plate 19 centrally and at the same angular spacing about the axis 15, which engage in corresponding elongated holes 24 in the form of circular segments which are incorporated in the legs 12, 13. On the side of the axle 15 opposite the support wheels 21, a separating knife 25 is articulated by means of a base plate 27 to the support plate 19 by means of screws 26. A drive motor 28 for the cutting knife 25 is on the support plate 19 arranged, the latter in an abrupt swinging movement to lift the surface.
Wie bei dem in der Zeichnung dargestellten Ausfuhrungsbeispiel 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 exemplary embodiment shown in the drawing, in the working position of the device 10, the two drive wheels 16 are seated on the support surface 30 and drive the device 10 forward due to the ground friction in order to lift a covering from the support surface 30. The cutting knife 25 lies with its cutting edge on the support surface 30 so that it can work between the covering and the support surface 30. In this working position, the support wheels 21 hang in the air above the contact surface 30.
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 a piece or a web of the covering has been lifted off, the device 10 must be moved back to a new place of use. Therefore, the device 10 can be placed on the support wheels 21 before it is moved back by a tilting movement in the direction of arrow D, as a result of which the drive wheels 16 are lifted off the support surface 30 (cf. FIGS. 3 and 4). In this process, the bolts 23 run against one end of the elongated holes 24, so that the drive wheels 16 and the cutting knife 25 hang in the legs 12, 13. Now the device 10 can be pulled back to the new location in a comfortable backward movement. The motor 17 and also the drive motor 28 can continue to run without this interfering with the return movement of the device 10.
