Finally, the electric drive motor allows for the operator a substantial relief at work. The wallpaper to be perforated can be treated faster, so that also saves time when removing the wallpaper occurs. It is recommended that the guard member is hooded and covers the carrier, the perforating tools, and the wallpaper portion to be worked to ensure that no parts are thrown from the perforating tool to the operator and that there is no injury from being used by the perforating tool since the guard forms a contact portion , Finally, it is further ensured that the perforation tools are not against any edges or the like. can be pushed and thus cause damage.
Vorteilhafterweise ist die Halterung des Trägers als Einstellhülse ausgebildet und am Schutzteil festgelegt. Hierbei umgreift ein am Schutzteil festgelegter Klemmring die Einstellhülse. Durch eine solche Halterung ist es möglich, das Schutzteil bezüglich der Perforierungswerkzeuge über die Einstellhülse höhenverstellbar zu gestalten. Durch den Klemmring selber ist eine sichere Festlegung gegeben. Hierbei empfiehlt es sich, dass der Klemmring ein Innengewinde aufweist und die Einstellhülse ein Außengewinde, wobei die Einstellhülse drehbar im Klemmring gelagert ist. Durch Drehung der Einstellhülse in Verbindung mit Innen- und Außengewinde kann somit bezüglich der Perforierungswerkzeuge das Schutzteil abgesenkt oder von der Tapete abgehoben werden, während der Träger selber bezüglich seiner Lage unveränderbar bleibt. Besonders empfehlenswert ist es, wenn eine Schraubverbindung zur Festlegung des Klemmringes am Schutzteil sich nur über einen geringen Winkelbereich des Klemmringes erstreckt, so dass bei Betätigung der Spannschraube der Durchmesser des Spannringes verkleinerbar oder vergrößerbar ist. Bei gelockerter Spannschraube besteht die Möglichkeit, die Einstellhülse leicht und feinfühlig zu drehen.Advantageously, the holder of the carrier is designed as an adjusting sleeve and fixed to the protective part. Here, a fixed on the protective part clamping ring surrounds the Adjusting. By such a holder, it is possible to make the protective part with respect to the perforating tools on the adjusting height adjustable. By the clamping ring itself a secure determination is given. Here, it is recommended that the clamping ring has an internal thread and the adjusting sleeve has an external thread, wherein the adjusting sleeve is rotatably mounted in the clamping ring. By rotation of the adjusting sleeve in conjunction with internal and external thread can thus be lowered with respect to the perforating the protective part or lifted from the wallpaper, while the carrier itself remains unchangeable with respect to its position. It is particularly advisable if a screw for fixing the clamping ring on the protective part extends only over a small angular range of the clamping ring, so that upon actuation of the clamping screw, the diameter of the clamping ring is reduced or enlarged. When the clamping screw is loosened, it is possible to turn the adjusting sleeve easily and sensitively.
Vorteilhafterweise sind am Träger am Drehumfang gleichmäßig bezüglich des Drehumfanges verteilt Perforierungswerkzeuge angeordnet, um so beim Perforieren einen gleichmäßigen Anpressdruck zu erzielen und eine gleichmäßige Einpressung zu erzielen. Empfehlenswerterweise ist das Perforierungswerkzeug als Kreismesser vorzugsweise als Doppelkreismesser ausgebildet. Die Messerschneide selber trägt dann einzelne zahnartig Spitzen, die die Perforierung der Tapete durchführen. Das Werkzeug wird über den Träger angetrieben, wobei die Kreismesser sich selber auf der Tapete abwälzen, so dass nacheinander die Messerschneide mit ihren Spitzen in die Tapete eindringen.Advantageously, perforation tools are arranged on the support at the rotation circumference, distributed uniformly with respect to the rotation circumference, so as to achieve a uniform contact pressure during perforation and to achieve uniform insertion. The perforating tool is preferably designed as a circular knife, preferably as a double-circle knife. The knife edge itself then carries individual tooth-like tips that perform the perforation of the wallpaper. The tool is driven by the carrier, the circular blades roll themselves on the wallpaper, so that successively penetrate the knife edge with their tips in the wallpaper.
Bei einem besonderen Ausführungsbeispiel der Erfindung ist der Träger aus einem Drehkranz und einem Drehbolzen aufgebaut. Hierbei ist der Drehkranz an dem Drehbolzen drehfest gehaltert. Der Drehbolzen erlaubt eine sichere Lagerung des Drehkranzes, während der Drehkranz selber die Perforierungswerkzeuge aufnehmen kann, so dass ein gleichmäßiger Antrieb erfolgt.In a particular embodiment of the invention, the carrier is composed of a turntable and a pivot pin. Here, the turntable is rotatably supported on the pivot pin. The pivot pin allows safe storage of the turntable, while the turntable itself can accommodate the perforation tools, so that a uniform drive takes place.
Vorteilhafterweise sind die am Träger angeordneten, um eine Achse drehbaren Perforierungswerkzeuge als Walzen mit Spitzen ausgebildet, so dass über den Anpressdruck und der Drehbewegung nacheinander die Spitzen der Walzen sich in die Tapete eindrücken können und somit gleichmäßig eine Perforierung der Oberfläche der Tapete durchführen. Um eine möglichst leichte Bedienung zu erzielen, ist das dem Drehkranz abgewandte Bolzenende mit einer biegsamen Welle versehen, die ihrerseits über einen Elektromotor antreibbar ist. Durch die biegsame Welle ist die Handlichkeit der Vorrichtungen selber erhöht. Die Vorrichtung kann auf die zu perforierende Tapete gedrückt werden, während die Drehbewegung durch einen Elektromotor erfolgt. Hierbei kann den Elektromotor beispielsweise der Benutzer tragen, wobei der Elektromotor über eine Batterie antreibbar ist. Zur Bedienungsvereinfachung und Handlichkeit des Gerätes ist das die biegsame Welle tragende Bolzenende in einem Handgriff angeordnet. Für den Benutzer ist daher der Antrieb nicht störend. Um festzustellen, wie tief die Perforierungsspitzen des Werkzeugs herausragen, ist der Drehwinkel der Einstellhülse bezüglich des Klemmrings anzeigbar. Der Drehwinkel selber ist dann ein Maß für die Eindringtiefe des Perforierungswerkzeugs in die Tapete.Advantageously, arranged on the carrier, about an axis rotatable perforating tools are formed as rollers with tips, so that on the contact pressure and the rotational movement successively the tips of the rollers in can press the wallpaper and thus perform a uniform perforation of the surface of the wallpaper. In order to achieve the easiest possible operation, the bolt end facing away from the turntable is provided with a flexible shaft, which in turn can be driven by an electric motor. Due to the flexible shaft, the handiness of the devices itself is increased. The device can be pressed onto the wallpaper to be perforated, while the rotational movement is performed by an electric motor. Here, the electric motor, for example, carry the user, wherein the electric motor is driven by a battery. To simplify operation and manageability of the device which carries the flexible shaft bolt end is arranged in a handle. For the user, therefore, the drive is not disturbing. In order to determine how deep the perforation tips of the tool protrude, the angle of rotation of the adjusting sleeve with respect to the clamping ring can be displayed. The angle of rotation itself is then a measure of the penetration depth of the perforation tool in the wallpaper.
Um beim Perforieren sicherzustellen, dass die Vorrichtung sich nicht durch Tapetenteile verstopft, trägt das haubenartige Schutzteil an seinem Umfang Auswurföffnungen, die sich am Umfang der Haube aus erstrecken. Bei Drehung des Trägers und damit einer Bewegung der Perforierungswerkzeuge können dann die Tapeten oder Farbreste herausgeschleudert werden und kommen von dem haubenartigen Schutzteil frei.In order to ensure that the device is not clogged by wallpaper parts during perforation, the hood-like protective part carries at its periphery ejection openings which extend at the periphery of the hood. Upon rotation of the carrier and thus a movement of the perforating tools then the wallpaper or ink residue can be ejected and released from the hood-like protection part.
Um die Perforierungsteile leicht auswechseln zu können, empfiehlt es sich, dass der Schutzteil an seinem Umfang weiter eine Durchstecköffnung hat. Durch diese kann ein Werkzeug zu einer das Perforierungswerkzeug an dem Träger halternde Schraube geführt werden, um diese zu Lösen und das Werkzeug auszuwechseln. Um die einzelnen drehbaren Perforierungswerkzeuge an seinem Umfang leicht am Drehkranz befestigen zu können, weist dieser Gewindeöffnungen zur Halterung der Drehachse auf, auf denen Perforierungswerkzeuge angeordnet sind, wobei in diese Gewindeöffnungen, die Achse der Perforierungswerkzeuge einschraubbar sind. Hierbei empfiehlt es sich, dass die Gewindeöffnungen radial zur Drehachse des Drehkranzes sich erstrecken, um somit eine gleichmäßige Drehung der Perforierungswerkzeuge zu erhalten. Bei einem anderen Ausführungsbeispiel verlaufen die Gewindeöffnungen tangential zur Drehachse. Bei einer Drehbewegung des Drehkranzes üben die punktuellen Perforationswerkzeuge eine leicht schleifende Bewegung aus, so dass ein Anreißen der Tapete erfolgt.In order to easily replace the Perforierungsteile, it is recommended that the protective part at its periphery further has an insertion opening. Through this, a tool can be performed to the perforating tool on the carrier halternde screw to release them and replace the tool. To easily attach the individual rotatable perforating tools on its circumference on the turntable, this has threaded openings for holding the axis of rotation on which perforation tools are arranged, in which threaded openings, the axis of the perforation tools are screwed. Here, it is recommended that the threaded openings extend radially to the axis of rotation of the turntable, so as to obtain a uniform rotation of the perforating tools. In another embodiment, the threaded openings extend tangentially to the axis of rotation. In a rotary motion of the turntable exercise the punctiform perforation tools a slight grinding movement, so that a tearing of the wallpaper is done.
Bei einem besonderen Ausführungsbeispiel der Erfindung trägt der Drehkranz und/oder der Drehbolzen eine radial an seiner Drehachse sich erstreckende Scheibe für eine zu bearbeitende Wandfläche. Bei einem solchen Ausführungsbeispiel ist praktisch der gesamte Innenraum durch das Bearbeitungswerkzeug abgedeckt. Hierbei ist es günstig, wenn die Scheibe aus zwei Scheibenabschnitten aufgebaut ist, wobei der eine Scheibenabschnitt Öffnungen für stiftartige Perforationswerkzeuge aufweist und die Stiftenden in der Scheibe durch einen zweiten Scheibenabschnitt gegen ein Herausschieben aus der Öffnung gehalten sind. Hierdurch ist wiederum eine gleichmäßige Bearbeitung möglich. Darüber hinaus wird sichergestellt, dass unterschiedliche Bearbeitungswerkzeuge eingesetzt werden können.In a particular embodiment of the invention, the turntable and / or the pivot pin carries a radially extending at its axis of rotation disk for a wall surface to be processed. In such an embodiment, virtually the entire interior is covered by the machining tool. In this case, it is expedient if the disk is made up of two disk sections, wherein the one disk section has openings for pin-like perforation tools and the pin ends in the disk are held against being pushed out of the opening by a second disk section. As a result, a uniform processing is possible again. It also ensures that different editing tools can be used.

Unten aus dem haubenartigen Schutzteil 11 ragen kreismesserartige Perforierungswerkzeuge 18 heraus, die mit einer Spitze in der zu perforierenden Tapete 19 eingreifen, die ihrerseits auf einem Untergrund aufklebbar ist. Nachzutragen sei hier noch, dass der Klemmring über eine nicht näher bezeichnete Schraube die Einstellhülse 12 reibschlüssig bezüglich der Drehbewegung haltern kann. Die Perforierungseinrichtung nach

Der Drehbolzen 14 ist drehfest mit einem Drehkranz 24 über eine Befestigungsschraube 25 verbunden. Hierbei bilden Drehbolzen und Drehkranz den Träger für das Perforierungswerkzeug 18. Der Drehbolzen 14 ist mittels einer Kugellageranordnung in der Einstellhülse 12 anordnet, wobei die Kugellager durch nicht näher bezeichnete Seegerringe in der Einstellhülse 12 gehaltert sind.The
Der Klemmring 13, in dem die Einstellhülse 12 drehbar gelagert ist, ist mittels einer Schraubverbindung 33 an dem Schutzteil 11 befestigt. Es sei hier erwähnt, dass die Schraubverbindung 33 mit mehreren Schraubenabschnitten an dem Schutzteil 11 befestigt ist. Der Spannring wird über eine Spannschraube 34 an dem Außenumfang der Einstellhülse festgelegt.The clamping
Der Drehkranz 24 trägt gleichmäßig über seinen Umfang bzw. um seine Befestigungsschraube 25 herum Gewindeöffnungen 29. Diese Gewindeöffnungen 29 nehmen eine Drehachse 27 auf, die ihrerseits an einem Ende mit einem Außengewinde versehen ist und an ihrem anderen Ende das Perforierungswerkzeug tragen, das mittels einer Halteschraube 28 an der Drehachse 27 gelagert ist. Das Perforierungswerkzeug ist als ein Doppelkreismesser 26 ausgebildet. Dieses Kreismesser ist frei drehbar. Es wälzt sich mit seinem Umfang bei Drehung des Drehkranzes auf einer zu perforierenden Tapete 19 ab. Der Umfang 32 des Kreismessers ist gezahnt, wobei die Zahnung oder die zahnartigen Spitzen in die Tapete 19 eingreifen.The
Der Schutzteil 11 ist haubenartig ausgebildet. Er ist mit einer Auswurföffnung 30 versehen sowie mit einer Durchstecköffnung 31. Die Auswurföffnung dient dazu, bei der Perforierung abgerissene Tapetenreste aus der Öffnung herauszufördern, um zu verhindern, dass sich das Perforierungswerkzeug festsetzt, eine solche Auswurföffnung 30 wird dann benötigt, wenn das Perforierungswerkzeug 18 Perforierungsspitzen 35 trägt.The
Die Durchstecköffnungen dienen dazu, bei Auswechseln der Kreismesser die Halteschraube 28 zugänglich zu machen, so dass durch Wechseln der Kreismesser nicht die gesamte Perforierungsvorrichtung auseinandergebaut werden muss.The push-through openings are used to make the retaining

Sollte die Tapete aufgrund von Farbüberstrichen verdickt sein, so wird das Schutzteil 11 von der Tapete 19 etwas fortbewegt. Hierzu wird die Spannschraube 34 des Klemmringes gelöst, die Einstellhülse 12 im Uhrzeigersinn gedreht, so dass die Einstellhülse etwas tiefer in den haubenartigen Schutzteil 11 hineinragt. Durch diese Höhenverstellung können bei Aufsetzen des Schutzteiles des gezahnten Umfanges 32 diese tiefer in die Tapete eindringen, so der Abstand zwischen Schutzteil und das an der Tapete angreifende Kreismesser sich vergrößert. Umgekehrt wird, falls die Tapete in ihrer Dicke dünn ist, oder nur ein Anritzen der Tapete erfolgen soll, die Einstellhülse im Gegenuhrzeigersinn gedreht und der Drehkranz 24 mit dem Perforiermesser wird in den haubenartigen Schutzteil 11 gezogen.If the wallpaper is thickened due to color overstretching, the

Das Perforierungswerkzeug 18 besteht aus zwei Scheibenabschnitten 37, 38. Hierbei ist an dem Scheibenabschnitt 37 ein Abschnitt des Drehkranzes 24 unmittelbar angeformt. Der Scheibenabschnitt 38 trägt Halteöffnungen 36. In diesen Halteöffnungen, die in axialer Richtung abgesetzt sind, sind Perforierungsspitzen 35 eingesetzt. Die beiden Abschnitte 37, 38 werden dann durch Schrauben 39 aneinander befestigt, so dass die Perforierungsspitzen 35 nicht aus den Halteöffnungen 36 heraus können.The
Beide Scheibenabschnitte 37, 38 sind dann durch die Befestigungsschraube 25 an dem Drehbolzen 14 angeordnet. Bei Drehung des Drehbolzens dreht sich dann die gesamte Scheibe 37, 38 mit und perforiert somit die Tapete.Both

Bei einer Drehbewegung rollen die Walzen mit ihren Spitzen 41 auf der Tapete 19 ab, wenn sich der Drehkranz 24 dreht. Die Walzen 40 sind auf der Drehachse 27 drehbar angeordnet. Durch die tangentiale Anordnung der Gewindeöffnungen entsteht ein Perforieren, eine leichte Versetzung der Perforation, so dass die Tapete 19 leicht angeschnitten wird.During a rotational movement, the rollers roll with their tips 41 on the

Wie bereits erwähnt, sind die dargestellten Ausführungsformen nur beispielsweise Verwirklichungen der Erfindung. Diese sind nicht darauf beschränkt, vielmehr sind noch mancherlei Abänderungen und Anwendungen möglich. Beispielsweise könnte um die Bewegung der Einstellhülse zu vereinfachen, die Einstellhülse mit einem Drehgriff ausgestattet sein. Die scherenartigen Perforierungswerkzeuge könnten auch insoweit umgeändert werden, dass der eine Abschnitt einen Schleifabschnitt tragen würde, um so Unebenheiten auf dem Untergrund abschleifen zu können oder auch Tapetenreste zu entfernen. Schließlich sei noch vorgetragen, dass der Antriebsmotor auch unmittelbar an dem herausragenden Teil des Drehbolzens angeordnet wäre. Es braucht dann lediglich die Stromverbindung zu einer Batterie od.dgl. angeschlossen werden. Der Handgriff könnte dann als Fortsetzung des Drehbolzens wieder wirken bzw. auf den Elektromotor aufgesetzt sein. Weiter sei noch vorgetragen, dass der Haubenrand des Schutzteiles abgerundet sein könnte, um so mit der Perforierungsvorrichtung eine leichtere Schiebebewegung auf der Tapete durchführen zu können. Bei einem einfachen Ausführungsbeispiel besteht der Schutzteil aus einzelnen Stangen, die rund um den Träger mit dem Perforierungswerkzeug angeordnet sind.As already mentioned, the illustrated embodiments are only examples of implementations of the invention. These are not limited to this, but rather many modifications and applications are possible. For example, to facilitate movement of the adjustment sleeve, the adjustment sleeve could be equipped with a twist grip. The scissors-like perforation tools could also be changed to the extent that the one section would wear a sanding section in order to be able to sand off unevenness on the ground or to remove wallpaper residues. Finally, it should be stated that the drive motor would also be arranged directly on the protruding part of the pivot pin. It then only needs the power connection to a battery or the like. be connected. The handle could then act as a continuation of the pivot pin again or be placed on the electric motor. It should also be said that the hood edge of the protective part could be rounded so as to be able to perform a lighter sliding movement on the wallpaper with the perforating device. In a simple embodiment, the protective part consists of individual rods which are arranged around the carrier with the perforating tool.
