Abstract

1. A device for memoving paint, carpet and/or material debris from a surface, comprising a cutting plate (1) rigidly coupled to a vibration generator (9) and having cutting edges (5, 5') on two of parallel opposite peripheral sides, which cutting edges are each connected with the cutter plate through a transition portion and define an acute angle with respect to the working surface, characterized in that - the cutter plate (1) is positioned below the housing of the vibration generator (9), and - the transition portions are defined by obliquely outwardly extending edge parts (4, 4') which are spring-resiliently joined to the cutter plate (1) and the cutting strips (2, 2') provided with the cutting edges (5, 5') by further curved transition portions (12, 13).

Description

Die Erfindung betrifft eine Vorrichtung zum Entfernen von Farb-, Teppich- und/oder Materialresten von einer Fläche, mit an einem Schwingungserreger befestigter Schneidplatte, die an zwei einander parallel gegenüberliegenden Umfangsseiten mit Schneiden versehen ist, die über je einen Übergangsbereich mit der Schneidplatte in Verbindung stehen und einen spitzen Winkel zur Bearbeitungsfläche bilden.The invention relates to a device for removing paint, carpet and / or material residues from a surface, with a cutting plate attached to a vibration exciter, which is provided on two mutually parallel circumferential sides with cutting edges, each of which has a transition area in connection with the cutting plate stand and form an acute angle to the processing surface.

Das Entfernen derartiger Materialreste fällt bei der Rεnovierung von Wohn- oder Geschäftsräumen nach der Abnahme von Tapeten, Fußbodenbelägen, Verkleidungen oder ähnlichem an. In diesen Fällen werden die an den zu renovierenden Flächen verbliebenen Reste von Farben, Kunststoffen, Klebemitteln oder auch von zu entfernendem Material von Hand mit einem Spachtel oder mit Hilfe von maschinellen Schleifgeräten in mühevoller Arbeit entfernt. Von Nachteil dabei ist nicht nur der hohe Arbeitsaufwand, sondern auch der erhebliche Verbrauch von Schleifmitteln.The removal of such material residues occurs when renovating residential or business premises after the removal of wallpaper, floor coverings, cladding or the like. In these cases, the remains of paints, plastics, adhesives or material to be removed on the surfaces to be renovated are removed laboriously by hand with a spatula or with the help of mechanical grinders. The disadvantage here is not only the high workload, but also the considerable consumption of abrasives.

Es sind jedoch auch Vorrichtungen bekannt (US-A-2 984 908), die mit Hilfe beweglicher Schneidplatten arbeiten, die über ein Exzentergetriebe gegenüberliegend in hin- und hergehende Bewegung versetzt werden. Bei dieser Vorrichtung liegt der Mittelbereich des Gerätes auf der zu bearbeitenden Fläche auf. Bei dieser Vorrichtung wird daher das Gewicht des Schwingungserregers nicht genutzt, sondern lediglich die Federkraft, die bei der Durchbiegung der Schneiden erzeugt wird. Die bekannte Vorrichtung hat sich nicht durchsetzen können, da von den Schneiden keine ausreichende Kraft auf die Reste ausgeübt wird.However, devices are also known (US-A-2 984 908) which operate with the aid of movable cutting plates which are set reciprocally in motion by means of an eccentric gear. In this device, the center area of the device rests on the surface to be processed. In this device, therefore, the weight of the vibration exciter is not used, but only the spring force that is generated when the cutting edges deflect. The known device has not been able to assert itself because the cutting edges do not exert sufficient force on the remnants.

Weiterhin ist eine Vorrichtung bekannt (US-A-3 811 160), bei der an die vibrierende Platte eines Schwingschleifers eine durchgehende Platte befestigt ist, an deren Enden zwei Schneiden senkrecht nach unten zeigen. Nachteilig bei dieser Vorrichtung ist es, daß die senkrecht stehenden Schneiden sich in eine Oberfläche einrütteln und Beschädigungen erzeugen können. Die Vorrichtung muß daher sehr sorgfältig von Hand geführt werden und muß ständig in Bewegung sein.Furthermore, a device is known (US-A-3 811 160), in which a continuous plate is attached to the vibrating plate of an orbital sander, at the ends of which two cutting edges point vertically downwards. A disadvantage of this device is that the vertical cutting edges shake into a surface and can cause damage. The device must therefore be guided very carefully by hand and must be constantly in motion.

Schließlich sei noch auf die DE-A-2 818 073 hingewiesen. Bei dieser Vorrichtung ist an einer gedämpft an einem Schwingungserreger aufgehängten Platte eine Schneidklinge befestigt. Die Maschine treibt über die Platte die Schneidklinge mit einer oszillierenden Bewegung an, die in der Ebene der Platte verläuft. Das mit der Schneidklinge bestückte Schälwerkzeug ist nur an einer Seite der Maschine angeordnet, so daß diese während des Arbeitens schräg angehoben und geführt werden muß. Das Anheben kann auch durch eine Stützrolle erleichtert werden.Finally, reference is made to DE-A-2 818 073. In this device, a cutting blade is attached to a plate suspended from a vibration exciter. The machine drives the cutting blade over the plate with an oscillating movement that runs in the plane of the plate. The peeling tool equipped with the cutting blade is only arranged on one side of the machine, so that it has to be lifted and guided at an angle during work. Lifting can also be facilitated by a support roller.

Nachteil dieser Vorrichtung ist es, daß die Klingenstellung offenbar sehr genau eingestellt werden muß, damit der Schälvorgang optimal verläuft. Das ist bei Handführung ermüdend und verkrampfend. Die radgestützte Ausführung erfordert aber einen erheblichen technischen Mehraufwand, insbesondere muß auch die Klinge verstärkt werden, damit das Zusammenspiel von Oszillation, Klingenvorschub und Arbeitsgeschwindigkeit zu einem optimalen Ergebnis führt. Für einen Heimwerker ist daher die radgestützte Vorrichtung zu kostspielig.The disadvantage of this device is that the blade position must obviously be set very precisely so that the peeling process runs optimally. This is tiring and cramping with hand guidance. However, the wheel-supported design requires considerable additional technical effort, in particular the blade must also be reinforced so that the interaction of oscillation, blade feed and working speed leads to an optimal result. The wheel-based device is therefore too expensive for a handyman.

Für die Erfindung besteht damit die Aufgabe, eine Vorrichtung der eingangs genannten Art zu schaffen, mit deren Hilfe unter Überwindung bisher bestehender Schwierigkeiten und Nachteile eine rationelle, ermüdungsfreie und rasch fortschreitende Arbeitsweise bei der Entfernung von Materialresten ermöglicht wird, wobei die Vorrichtung leicht zu handhaben und preisgünstig zu verwirklichen sein muß.The object of the invention is therefore to provide a device of the type mentioned at the outset, with the aid of which a rational, fatigue-free and rapidly progressing method of removing material residues is made possible by overcoming existing difficulties and disadvantages, the device being easy to handle and must be inexpensive to implement.

Die Lösung dieser Aufgabe gelingt mit einer Vorrichtung der eingangs genannten Art, die folgende Einzelheiten aufweist:

  • - die Schneidplatte ist unterhalb des Gehäuses des Schwingungserregers angeordnet,
  • - die Übergangsbereiche zu den Schneiden sind durch schräg nach außen verlaufende Randpartien gebildet, die mit der Schneidplatte und den mit den Schneiden versehenen Schneidstreifen durch Radiusübergänge federnd-elastisch verbunden sind.
This object is achieved with a device of the type mentioned at the beginning, which has the following details:
  • the cutting plate is arranged below the housing of the vibration exciter,
  • - The transition areas to the cutting edges are formed by obliquely outwardly extending edge parts which are connected to the cutting plate and the cutting strips provided with the cutting edges by resiliently elastic transitions.

Mit der Vorrichtung gemäß Erfindung wird im Unterschied zum Stand der Technik eine rationelle und ermüdungsfreie Arbeitsweise dadurch erreicht, daß die Schneiden in der Frequenz der Schwingung schneidende und hobelnde Arbeitshübe in der Größenordnung der Schwingungsamplitude vollführen, die die als Erhebungen auf der zu glättenden Fläche stehenden Materialreste wirksam abhebt. Eine Kontrolle der Schrägstellung der Maschine oder der Schneiden ist nicht erforderlich.With the device according to the invention, in contrast to the prior art, an efficient and fatigue-free mode of operation is achieved in that the cutting edges in the frequency of the vibration cutting and planing working strokes in the order of magnitude of the vibration amplitude are carried out by the material residues standing as elevations on the surface to be smoothed takes off effectively. It is not necessary to check the inclination of the machine or the cutting edges.

Dadurch, daß die Schneidplatte mit ihrer charakteristischen, erfindungsgemäßen Anordnung und Formgebung mit abgeschrägten Rändern und im spitzen Winkel zur bearbeiteten Fläche auslaufenden Schneiden ausgestattet ist, wobei die abgeschrägten Randpartien der Schneidplatte eine gewisse federnd-elastische Wirkung haben, wird ein wirkungsvolles Schneiden erreicht, ohne daß die zu glättende Fläche angegriffen wird. Die Höhe, mit der die Schneidplatte über der Fläche liegt, kann verschieden hoch sein.Because the cutting plate with its characteristic arrangement and shape according to the invention is equipped with bevelled edges and cutting edges tapering at an acute angle to the machined surface, the bevelled edge parts of the cutting plate having a certain resilient-elastic effect, effective cutting is achieved without the surface to be smoothed is attacked. The height at which the cutting insert lies above the surface can be of different heights.

Die Schneidplatte hat eine polygonale, vorzugsweise eine rechteckige, im Mittelbereich aufgewölbte Grundfläche und zwei annähernd parallele Ränder mit Schneiden. Die Schneiden selbst können gerade, aber auch gezahnt oder gezackt sein.The cutting plate has a polygonal, preferably a rectangular, bulging base in the central region and two approximately parallel edges with cutting edges. The cutting edges themselves can be straight, but they can also be serrated or serrated.

Bei den verschiedenen Ausführungsformen ergibt sich außerdem der Vorteil, daß die Vorrichtung mit einem handelsüblichen Schwingschleifer als Antrieb für relativ geringe Anschaffungskosten als neue, leistungsfähige Vorrichtung zur Verfügung steht, die viele einschlägige Glättarbeiten erleichtert.In the various embodiments there is also the advantage that the device with a commercially available orbital sander as a drive for relatively low purchase costs as a new, powerful Vorrich is available, which facilitates many relevant smoothing work.

Im folgenden wird die Erfindung anhand eines Ausführungsbeispieles in der Zeichnung dargestellt und dabei näher erläutert. Es zeigt

  • Fig. 1 eine Vorrichtung nach der Erfindung in perspektivischer Darstellung;
  • Fig. 2 eine Vorderansicht der Vorrichtung gemäß Fig. 1;
  • Fig. 3 eine andere Darstellung;
  • Fig. 4 ein Randdetail bei der Schneide gemäß den Fig. 1 und 3;
  • Fig. 5a und 5b zwei verschiedene Klingenformen.
The invention is illustrated below using an exemplary embodiment in the drawing and is explained in more detail. It shows
  • Figure 1 shows a device according to the invention in perspective.
  • FIG. 2 shows a front view of the device according to FIG. 1;
  • 3 shows another representation;
  • 4 shows an edge detail in the cutting edge according to FIGS. 1 and 3;
  • 5a and 5b two different blade shapes.

Die Schneidplatte hat üblicherweise eine rechteckige Gestalt, deren Mittelbereich aufgewölbt ist und die zwei parallele Ränder mit nach unten überstehenden Schneiden besitzt, während die Stirnseiten schneidenlos sind. Die in der Fig. 1 dargestellte Form entspricht nicht dieser Form, da sie eine Ausführungsform mit zwei Schneidstreifen anstelle einer Platte zeigt.The cutting tip usually has a rectangular shape, the central region of which is arched and which has two parallel edges with downwardly protruding cutters, while the end faces are cutless. The shape shown in Fig. 1 does not correspond to this shape, since it shows an embodiment with two cutting strips instead of a plate.

Fig. 1 zeigt die Vorrichtung gemäß Erfindung in arbeitsbereitem Zustand. Eine aus zwei Schneidstreifen 2, 2' und der Unterlage 1' bestehende Schneidplatte 1 erstreckt sich in ihrer Mittelpartie annähernd parallel zu der zu bearbeitenden Fläche 3 und ist dabei in der Mittelpartie oberhalb der zu bearbeitenden Fläche angeordnet. Die Schneidplatte 1 steht mit dieser über die Schneidstreifen 2, 2' in Kontakt. Letztere sind in Richtung auf die Fläche 3 abgeschrägt, wobei die Randpartien 4, 4' mit Schneiden 5, 5' versehen sind. Die Schneiden 5, 5' sind zu diesem Zweck durch ein bei Schneidwaren dem Fachmann bekanntes Verfahren gehärtet. Die Schneiden 5, 5' laufen im spitzen Winkel αzur Fläche 3 aus. Auf der Fläche 3 vorhandene, zu entfernende Materialreste 7, 7' werden, wie aus der Darstellung in den Figuren deutlich erkennbar, in einer Kombination von kleinhübigen, in rascher Folge mit der Frequenz der Schwingung erfolgenden Schneid- und/oder Hobelbewegungen abgehoben.Fig. 1 shows the device according to the invention in a workable state. A cutting plate 1 consisting of two cutting strips 2, 2 'and the base 1' extends in its central part approximately parallel to the surface 3 to be processed and is arranged in the central part above the surface to be processed. The cutting plate 1 is in contact with it via the cutting strips 2, 2 '. The latter are beveled in the direction of the surface 3, the edge parts 4, 4 'being provided with cutting edges 5, 5'. For this purpose, the cutting edges 5, 5 'are hardened by a method known to those skilled in the art of cutlery. The cutting edges 5, 5 'run at an acute angle α to the surface 3. Material residues 7, 7 'present on the surface 3 are lifted off, as can be clearly seen from the illustration in the figures, in a combination of small-scale cutting and / or planing movements which occur in rapid succession with the frequency of the oscillation.

Die eigentliche ein- oder mehrteilige Schneidplatte 1 kann zum Schärfen oder nach Verschleiß nach dem Lösen der Befestigungselemente, beispielsweise in Form von Schrauben 8, von dem eigentlichen Schwingungserreger 9 gelöst werden. Dabei sind die Schraubenbohrungen in der Schneidplatte 1 so angeordnet, daß sie mit den vorhandenen Bohrungen handelsüblicher Schwingschleifer übereinstimmen.The actual one-part or multi-part insert 1 can be released from the actual vibration exciter 9 for sharpening or after wear after loosening the fastening elements, for example in the form of screws 8. The screw holes in the cutting plate 1 are arranged so that they match the existing holes of conventional orbital sander.

Wie aus den Figuren weiterhin zu erkennen ist, besitzt der Schwingungserreger 9 einen oder mehrere Handgriffe 10. Weiterhin ist eine elektrische Zuleitungsschnur vorhanden, die jedoch im vorliegenden Falle nicht dargestellt ist. Demgemäß handelt es sich bei den gezeigten Ausführungen um motorisch angetriebene Schwingschleifer handelsüblicher, dem Fachmann vertrauter Bauart. Solche bekannten Geräte sind entweder als Kreisschwinger oder als Linearschwinger ausgebildet, wobei auch beide, alternativ an einem Gerät einstellbare Schwingungsarten bei handelsüblichen Geräten möglich sind. Für die Erfindung eignen sich, wie Versuche ergeben haben, beide Schwingungsarten. Diese sind im übrigen in der Darstellung mit den Pfeilen 11 (Kreisschwinger) und 11' (Linearschwinger) symbolisiert.As can also be seen from the figures, the vibration exciter 9 has one or more handles 10. Furthermore, an electrical supply cord is present, which is not shown in the present case, however. Accordingly, the designs shown are motor-driven orbital sanders of a commercially available type which are familiar to the person skilled in the art. Such known devices are designed either as circular oscillators or as linear oscillators, both types of oscillation, which can alternatively be set on one device, being possible with commercially available devices. As tests have shown, both types of vibration are suitable for the invention. In the rest, these are symbolized by the arrows 11 (circular oscillators) and 11 '(linear oscillators).

Eine andere Ansicht zeigt die Fig. 3. Deutlich sind die beiden Schneidstreifen 2, 2' zu erkennen, die im Mittelbereich geteilt sind. Jeder der beiden Schneidstreifen 2, 2' besitzt Randpartien 4, 4', die in Schneiden 5, 5' auslaufen. Die Schneidplatte 1 kann auch in einer anderen Ausführungsform gestaltet sein, etwa in Form eines regelmäßigen Sechsecks.Another view is shown in FIG. 3. The two cutting strips 2, 2 ', which are divided in the central region, can be clearly seen. Each of the two cutting strips 2, 2 'has edge portions 4, 4' which end in cutting edges 5, 5 '. The cutting plate 1 can also be designed in another embodiment, for example in the form of a regular hexagon.

Eine etwas andere Formgebung der Randpartie 4 der Schneidplatte 1 zeigt Fig. 4. Dabei ist diese mit größeren Radiusübergängen 12, 13 ausgestattet. Hierdurch wird eine etwas weicher-elastische Wirkung erzielt, was in Abstimmung mit dem Schneiden-Material in einigen Fällen von Vorteil ist.A somewhat different shape of the edge part 4 of the cutting insert 1 is shown in FIG. 4. This is equipped with larger radius transitions 12, 13. This results in a somewhat softer-elastic effect, which is advantageous in some cases in coordination with the cutting material.

Zu erkennen ist auch in den Fig. 3 und 4 der spitze Winkel IX, den die Schneiden 5, 5' mit der Fläche 3 bildet. Dieser Winkel α liegt etwa zwischen 5 und 25°, ohne daß diese Winkelangaben letztlich limitierend sein sollen.3 and 4, the acute angle IX, which the cutting edges 5, 5 'forms with the surface 3, can also be seen. This angle α is approximately between 5 and 25 °, without this angle information ultimately being intended to be limiting.

Die Fig. 5a zeigt die Möglichkeit, die Schneiden mit einer geraden Schneidkante auszustatten, während die Fig. 5b eine gezackte Schneidkante darstellt.5a shows the possibility of equipping the cutting edges with a straight cutting edge, while FIG. 5b shows a serrated cutting edge.
