Abstract

A knife to be mounted in an oscillating tool for cutting through the adhesive that fastens a window pane in place, especially in a motor vehicle. To reduce the risk of damage to its edge and to the window frame or other areas of the vehicle body, the knife has a rest made out of a soft material, especially plastic, associated with at least one side of the blade.

Description

Die Erfindung bezieht sich auf ein Schneidmesser für ein Schneidwerkzeug mit Oszillationsantrieb zum Durchtrennen der Klebeschicht einer angeklebten Scheibe, insbesondere an einem Kraftfahrzeug (ein derartiges Schneidmesser ist z.B. aus der DE-A-3 210 212 bekannt). Bei modernen Kraftfahrzeugen werden die Scheiben, insbesondere Frontscheiben, zur Erzielung eines günstigeren Luftwiderstandsbeiwerts und teilweise auch aus anderen Gründen an die Karosserie angeklebt. Beim Auswechseln der Scheibe muss die teilweise recht massive und zähe Klebeschicht durchtrennt werden. Von Hand ist dies zumindest mit befriedigendem Ergebnis nicht möglich. Infolgedessen wurden Schneidwerkzeuge mit Oszillationsantrieb entwickelt, mit denen diese Klebeschicht recht zügig durchtrennt werden kann, so dass der Austausch einer beschädigten Scheibe, was lediglich das Schneiden angeht, keine Probleme mehr aufwirft. Es hat sich jedoch gezeigt, dass das oszillierend angetriebene Messer, welches in der Klebeschicht keinerlei Führung erfährt, seitwärts aus der Klebeschicht herauslaufen kann und dadurch Beschädigungen an der Karosserie bzw. allgemein gesprochen am Rahmen der Scheibe verursacht. Auch für das Messer selbst ist es nachteilig, wenn es an einem metallischen Körper aufläuft.The invention relates to a cutting knife for a cutting tool with an oscillation drive for cutting through the adhesive layer of a bonded pane, in particular on a motor vehicle (such a cutting knife is known, for example, from DE-A-3 210 212). In modern motor vehicles, the windows, in particular the front windows, are glued to the body to achieve a more favorable drag coefficient and sometimes also for other reasons. When replacing the pane, the sometimes very solid and tough adhesive layer must be cut through. This is not possible by hand, at least with a satisfactory result. As a result, cutting tools with an oscillation drive were developed, with which this adhesive layer can be severed very quickly, so that the replacement of a damaged disc, as far as cutting is concerned, no longer poses any problems. However, it has been shown that the oscillating knife, which is not guided in the adhesive layer, can run sideways out of the adhesive layer and thereby cause damage to the body or, generally speaking, to the frame of the pane. It is also disadvantageous for the knife itself if it strikes a metallic body.

Die Aufgabe der Erfindung besteht infolgedessen darin, ein Schneidmesser der eingangs genannten Art so weiterzubilden, dass die Beschädigungsgefahr für Messer und Rahmen, insbesondere an einer Kraftfahrzeugkarosserie, zumindest gemindert wird.The object of the invention is therefore to develop a cutting knife of the type mentioned at the outset so that the risk of damage to the knife and frame, in particular on a motor vehicle body, is at least reduced.

Zur Lösung dieser Aufgabe wird erfindungsgemäss vorgeschlagen, dass das Messer gemäss dem Oberbgriff des Anspruchs 1, entsprechend dem kennzeichnenden Teil dieses Anspruchs ausgebildet ist. Durch die Anbringung eines aus weichem Material, insbesondere aus Kunststoff, bestehenden Stützanschlags an einer Messerklinge, kann man letztere über diesen Stützanschlag entweder am Rahmen führen oder aber beim Herauslaufen aus der Klebeschicht am meist metallenen Rahmen abstützen, so dass Beschädigungen vermieden werden. Ein weiterer Vorteil besteht darin, dass eine metallische Berührung vermieden wird, was zu einer erheblichen Geräuschminderung führt.To achieve this object, it is proposed according to the invention that the knife is designed according to the preamble of claim 1, corresponding to the characterizing part of this claim. By attaching a support stop made of soft material, in particular plastic, to a knife blade, the latter can either be guided on the frame via this support stop or supported on the mostly metallic frame when it runs out of the adhesive layer, so that damage is avoided. Another advantage is that metallic contact is avoided, which leads to a considerable reduction in noise.

Der Stützanschlag muss einerseits ao angebracht werden, dass dieses Abstützen mit Sicherheit am Stützanschlag erfolgt und andererseits letzterer durch Durchtrennen, insbesondere das Einführen der Schneidmesserklinge in die Klebeschicht am Beginn des Durchtrennens, nicht behindert. Wenn der Stützanschlag nicht bereits zu Beginn des Schneidvorgangs am Rahmen anliegt, so ist das Schneidmesser so zu führen, dass ein eventuelles Herauslaufen aus der Klebeschicht nach der Seite hin erfolgt, auf der sich der Stützanschlag befindet. Dies gilt bei einer Ausführung, bei der sich lediglich an einer Fläche der Messerklinge ein Stützanschlag befindet.The support stop must be attached on the one hand so that this support is carried out with certainty on the support stop and on the other hand does not hinder the latter by cutting through, in particular the insertion of the cutting knife blade into the adhesive layer at the start of the cutting. If the support stop is not already in contact with the frame at the start of the cutting process, the cutting knife must be guided so that it may run out of the adhesive layer to the side on which the support stop is located. This applies to a version in which there is only a support stop on one surface of the knife blade.

Bei einem Schneidmesser, das zur Bildung eines Befestigungsteils und eines Schneidteils zweimal gegenläufig abgewinkelt ist, besteht eine besondere Ausgestaltung der Erfindung darin, dass der Stützanschlag am Schneidteil angebracht ist. Sowohl hinsichtlich seiner Form als auch seiner Grösse, beispielsweise seiner Dicke, ist dieser Stützanschlag an die Abmessungen des Schneidteils anzupassen, insbesondere an dem Abschnitt des Schneidteils, an dem er unmittelbar befestigt ist. Im übrigen ist die Befestigung so vorzunehmen, dass sie der beim Oszillationsantrieb auftretenden Belastung widersteht. Des weiteren ist darauf zu achten, dass der Kunststoff eine ausreichende mechanische Festigkeit hat, um den auftretenden mechanischen Belastungen standzuhalten, d.h. die Standzeit des Stützanschlags sollte derjenigen des Schneidmessers bzw. der Messerschneide möglichst entsprechen. Bei dem vorstehend beschriebenen Schneidmesser verläuft das Schneidteil leicht geneigt zur Ebene des Befestigungsteils, beispielsweise unter einem Winkel von ca. 15°. Im übrigen können die Schneiden in bekannter Weise als Doppelschneiden ausgebildet sein und als Klingenmaterial kommen hochwertige Messerstähle in Frage, die sich härten lassen. Unter «weichem Material» wird ein Kunststoff verstanden, der weicher ist als die Messerklinge und das Material, an dem die Klebeschicht anhaftet.In the case of a cutting knife which is angled twice in opposite directions to form a fastening part and a cutting part, a special embodiment of the invention consists in that the support stop is attached to the cutting part. Both in terms of its shape and its size, for example its thickness, this support stop must be adapted to the dimensions of the cutting part, in particular on the section of the cutting part to which it is directly attached. For the rest, the attachment is to be carried out in such a way that it resists the load occurring with the oscillation drive. It is also important to ensure that the plastic has sufficient mechanical strength to withstand the mechanical loads that occur, i.e. the service life of the support stop should correspond to that of the cutting knife or knife edge as far as possible. In the cutting knife described above, the cutting part runs slightly inclined to the level of the fastening part, for example at an angle of approximately 15 °. Otherwise, the cutting edges can be designed in a known manner as double cutting edges, and high-quality knife steels that can be hardened can be used as the blade material. “Soft material” means a plastic that is softer than the knife blade and the material to which the adhesive layer adheres.

Eine Weiterbildung der Erfindung sieht vor, dass sich der Stützanschlag im Bereich des freien, sich insbesondere verjüngenden Klingenendes befindet. Die Breite der Klinge bzw. der den Stützanschlag tragenden Fläche liegt dabei in der Grössenordnung von einem halben bis einem ganzen Zentimeter. Dementsprechend breit kann der Stützanschlag ausgebildet werden. Es ist allerdings möglich, dass der Stützanschlag auch eine etwas grössere Breite aufweist als die Messerklinge an der Befestigungsstelle.A further development of the invention provides that the support stop is located in the area of the free, in particular tapering, blade end. The width of the blade or the surface supporting the support stop is of the order of half to a full centimeter. The support stop can be made correspondingly wide. However, it is possible that the support stop also has a slightly larger width than the knife blade at the attachment point.

Bei einem Schneidmesser mit am freien Schneidmesserende gebildeter Schneide besteht eine weitere Ausbildung der Erfindung darin, dass der Stützanschlag als Rolle oder Zapfen ausgebildet ist und er etwa mit dem schneidenlosen'; vorzugsweise stärkeren Teil des Schneidmessers abschliesst. Er bildet eine Art Tiefenanschlag, mit dem man das Schneidmesser während des gesamten Schneidvorgangs abstützen und führen kann.In the case of a cutting knife with a cutting edge formed at the free end of the cutting knife, a further embodiment of the invention consists in the fact that the support stop is designed as a roller or a peg and it is approximately with the cuttingless one; preferably closes stronger part of the cutting knife. It forms a kind of depth stop with which you can support and guide the cutting knife during the entire cutting process.

Eine bevorzugte Ausführungsform der Erfindung kennzeichnet sich dadurch, dass der Aussendurchmesser des Stützanschlags geringfügig grösser ist als die Messerklingenbreite an der Befestigungsstelle, wobei er insbesondere beidseitig geringfügig übersteht. Bei sich chronisch verjüngender Klingenfläche wirt letztere gegen das Befestigungsende hin selbstverständlich breiter als der Aussendurchmesser des Stützanschlags, wie dies das entsprechende Ausführungsbeispiel der Zeichnung zeigt.A preferred embodiment of the invention is characterized in that the outside diameter of the support stop is slightly larger than the width of the knife blade at the fastening point, it protrudes slightly on both sides in particular. In the case of a chronically tapering blade surface, the latter is of course wider towards the fastening end than the outside diameter of the support stop, as the corresponding embodiment of the drawing shows.

Gemäss einer anderen Variante der Erfindung wird vorgeschlagen, dass der Stützanschlag als Kunststoff-Ummantelung eines Bereichs der Messerklinge bzw. des Zwischenteils ausgebildet ist. Dieses Schneidmesser kann nicht nur nach einer Seite hin, sondern zumindest nach zwei entgegengesetzten Seiten über einen Stützanschlag abgestützt werden.According to another variant of the invention, it is proposed that the support stop be designed as a plastic sheathing of an area of the knife blade or of the intermediate part. This cutting knife can be supported not only on one side, but at least on two opposite sides via a support stop.

Bei einem Schneidmesser, das zur Bildung eines Befestigungsteils und eines Schneidteils zweimal in gleichem Sinne abgewinkelt ist, besteht eine bevorzugte Ausgestaltung der Erfindung darin, dass sich der Stützanschlag am Zwischenteil zwischen dem Befestigungs- und dem Schneidteil befindet und er insbesondere dem Schneidteil benachbart ist. Insbesondere bei Anbringung des Stützanschlagsan lediglich einer Klingenfläche, ist es vorteilhaft, wenn ein harmonischer Übergang vom Stützanschlag in die meist in einem Radius vorgenommene Abwinkelung zum Schneidteil hin vorgenommen wird.In the case of a cutting knife which is angled twice in the same sense to form a fastening part and a cutting part, a preferred embodiment of the invention is that the support stop is located on the intermediate part between the fastening part and the cutting part and he in particular is adjacent to the cutting part. In particular, when the support stop is attached to only one blade surface, it is advantageous if a harmonious transition from the support stop to the angling, which is usually carried out in a radius, is made towards the cutting part.

Hierbei sieht eine Weiterbildung der Erfindung vor, dass der Stützanschlag als Kuppe oder Wulst ausgebildet und der Aussenfläche des Zwischenteils des etwa U-förmigen Schneidmessers zugeordnet ist. Die Krümmung der Kuppe kann durchaus auf den Abbiegeradius des Schneidteils abgestimmt werden bzw. diesem entsprechen.A further development of the invention provides that the support stop is designed as a dome or bead and is assigned to the outer surface of the intermediate part of the approximately U-shaped cutting knife. The curvature of the tip can certainly be matched to the bending radius of the cutting part or correspond to this.

Eine andere Ausbildung der Erfindung ist dadurch gekennzeichnet, dass das den Stützanschlag tragende Teilstück des Zwischenteils eine geringere Stärke aufweist als das restliche Zwischenteil, wobei dieses Teilstück und der Stützanschlag zusammen etwa gleich stark oder geringfügig stärker sind als das restliche Zwischenteil. Je nach Elastizität und Grösse des Stützanschlags wird letzterer, insbesondere bei der Kuppenform, mehr oder weniger elastisch zusammengedrückt. Falls also der Stützanschlag bzw. das freie Kuppenende beim losen Messer geringfügig übersteht, so kann dieser Überstand etwa dem Mass entsprechen, um welches der Stützanschlag im Betrieb elastisch zusammengedrückt wird. Im übrigen handelt es sich insoweit um geringe Grössen im Bereich von etwa einem Millimeter oder im Zehntelmillimeterbereich.Another embodiment of the invention is characterized in that the section of the intermediate part carrying the support stop has a smaller thickness than the rest of the intermediate part, this section and the support stop together being approximately the same or slightly stronger than the rest of the intermediate part. Depending on the elasticity and size of the support stop, the latter is compressed more or less elastically, particularly in the shape of the dome. If the support stop or the free tip end of the loose knife protrudes slightly, this projection can correspond approximately to the amount by which the support stop is compressed elastically during operation. For the rest, it concerns small sizes in the range of approximately one millimeter or in the tenth of a millimeter range.

Eine weitere bevorzugte Ausführungsform der Erfindung besteht darin, dass der Stützanschlag durch eine Kunststoff-Ummantelung, eines insbesondere in der Stärke reduzierten Bereichs des Zwischenteils, gebildet ist. Auch hier kommt eineStärke in der Grössenordnung von etwa einem Millimeter in Frage, bei einer Klingenstärke etwa in derselben Grössenordnung. Falls die Stärke des Zwischenteils nicht reduziert wird, oder der Stützanschlag dem nicht reduzierten Bereich des Zwischenteils zugeordnet wird, können sich etwas andere Werte ergeben, weil in der Regel der nicht reduzierte Bereich des Zwischenteils bzw. des Befestigungsteils eine Stärke in der Grössenordnung von etwa 2 mm aufweist.A further preferred embodiment of the invention consists in that the support stop is formed by a plastic sheathing, a region of the intermediate part that is reduced in thickness in particular. Here too, a thickness of the order of magnitude of approximately one millimeter is possible, with a blade thickness of approximately the same order of magnitude. If the thickness of the intermediate part is not reduced, or the support stop is assigned to the non-reduced area of the intermediate part, slightly different values may result, because the non-reduced area of the intermediate part or the fastening part usually has a thickness of the order of about 2 mm.

However, this does not imply that for certain applications the knives are also used as a flat design, as shown in FIGS. 1, 3, 5: and 7 or only curved ones are used instead of the angled versions. In addition, the shapes and in particular the fastening bores 1 (polygonal) and 2 (round bore) are only to be understood, for example, because this is at least not essential in connection with the design according to the invention. The outer contours that result from FIGS. 1, 3, 5 and 7 are only to be understood as basic representations, from which there can be substantial deviations, which is already evident from the fact that the representations of the figures mentioned are not identical, but are only approximately the same.

Erfindungsgemäss trägt die Messerklinge an wenigstens einer ihrer Klingenflächen, also beispielsweise an der in den Fig. 1, 3, 5 und 7 gegen den Betrachter weisenden Klingenfläche 3, einen Stützanschlag 4 bzw. 5 aus einem Material, welches wesentlich weicher ist als das Klingenmaterial. Insbesondere handelt es sich dabei um Kunststoff. Bei den Ausführungsformen der Fig. 5 bis 8 ist der Stützanschlag 6 bzw. 7 allen Klingenflächen zugeordnet, d.h. er ummantelt einen vorbestimmten Bereich des Schneidmessers. Im übrigen ist es denkbar, in besonderen Fällen auch zwei Stützanschläge nebeneinander anzuordnen oder diese mehrteilig auszubilden, falls dies im Hinblick auf die Rahmen und Scheibenausbildung Vorteile bringt.According to the invention, the knife blade carries at least one of its blade surfaces, for example on the blade surface 3 pointing towards the viewer in FIGS. 1, 3, 5, a support stop 4 or 5 made of a material which is substantially softer than the blade material. In particular, it is plastic. In the embodiments of FIGS. 5 to 8, the support stop 6 or 7 is assigned to all blade surfaces, i.e. it encases a predetermined area of the cutting knife. In addition, it is conceivable in special cases to also arrange two support stops next to one another or to form them in several parts, if this brings advantages with regard to the frame and pane design.

Das Schneidmesser der Fig. 2 ist zweimalig gegenläufig abgewinkelt, so dass ein Befestigungsteil 8 und ein Schneidteil 9 sowie ein Zwischenteil 10 entstehen. Das Befestigungsteil 8 ist mit der Befestigungsbohrung 1 versehen und dient zur unmittelbaren Befestigung an einem nicht gezeigten Schneidwerkzeug mit Oszillationsantrieb. Das Schneidteil 9 verläuft in einer Ebene, die mit derjenigen des Befestigungsteils 8 einen spitzen Winkel in der Grössenordnung von ca. 15° einschliesst. Ausserdem ist die Stärke des Schneidteils 9 absatzartig reduziert. Das dünnere Teilstück 11 ist als doppelschneidige Klinge ausgebildet und besitzt einen einer Ellipse angenäherten Zweikantquerschnitt mit nach entgegengesetzten Richtungen weisenden Messerschneiden 12 und 13. Am Übergang vom stärkeren Teilstück 14 zum dünneren Teilstück 11 befindet sich der Stützanschlag 4, der bei dieser Variante als Rolle oder Zapfen ausgebildet ist. Er besteht beispielsweise aus Polyamid und ist vorzugsweise mit Hilfe eines Niets, insbesondere Aluminiumniets, al Schneidmesser befestigt. Fig. 1 entnimmt man, dass der Durchmesser des Stützanschlags 4 geringfügig grösser ist als die Breite 15 der Klinge bzw. des Klingenteilstücks 14 im Bereich der Befestigungsstelle.The cutting knife of FIG. 2 is angled twice in opposite directions, so that a fastening part 8 and a cutting part 9 and an intermediate part 10 are created. The fastening part 8 is provided with the fastening bore 1 and is used for direct fastening to a cutting tool, not shown, with an oscillation drive. The cutting part 9 runs in a plane which, with that of the fastening part 8, forms an acute angle on the order of approximately 15 °. In addition, the thickness of the cutting part 9 is reduced in steps. The thinner section 11 is designed as a double-edged blade and has a two-sided cross-section approximating an ellipse with knife blades 12 and 13 pointing in opposite directions. At the transition from the thicker section 14 to the thinner section 11 there is the support stop 4, which in this variant is in the form of a roller or pin is trained. It consists for example of polyamide and is preferably attached as a cutting knife with the aid of a rivet, in particular aluminum rivet. Fig. 1 shows that the diameter of the support stop 4 is slightly larger than the width 15 of the blade or the blade section 14 in the area of the attachment point.

Bei den Varianten der Fig. 3 bis 8 ist das Schneidmesser im Gegensatz zum ersten Ausführungsbeispiel zweimal im gleichen Sinne abgewinkelt. Es entsteht eine U-Form. Auch sie setzt sich aus einem Befestigungsteil 1.6, einem Schneidteil 17 und einem diese verbindenden Zwischenteil 18 zusammen. Die Dicke des letzterenist wie beim Schneidteil 9 der Fig. 2 absatzartig reduziert. Das Stützglied 5 ist als Kuppe ausgebildet und dem dünneren Teilstück 19 des Zwisdhenteils 18 zugeosdnet. Es geht harmonisch in den Rahmen 20 am Übergang vom Zwischenteil 18 zum Schneidteil 17 über. Die Gesamtdicke des Stütz- ansehlags 5 und des dünrteren. Teilstücks 19 ist etwa gleich gross oder geringfügig grösser als die Dicke des stärkeren Teilstücks 21 des Zwischenteils 18. Im übrigen kann der Übergang vom stärkeren Teilstück 21 zum dünneren Teilstück 19 auch stetig oder über ein kurzes keilförmiges Zwischenstück gebildet werden. Ausserdem ist es durchaus möglich, den Stützanschlag 5 auf das stärkere Teilstück 21 aufzusetzen. In gleicher Weise gilt dies für das Ausführungsbeispiel der Fig. 2. Auch dort kann der absatzartige Übergang stetig erfolgen.In the variants of FIGS. 3 to 8, the cutting knife, in contrast to the first exemplary embodiment, is angled twice in the same sense. A U-shape is created. It also consists of a fastening part 1.6, a cutting part 17 and an intermediate part 18 connecting them. The thickness of the latter, like the cutting part 9 of FIG. The support member 5 is formed as a dome and is assigned to the thinner section 19 of the double section 18. It goes harmoniously into the frame 20 at the transition from the intermediate part 18 to the cutting part 17. The total thickness of the support ansehla g s 5 and the dünrteren. Section 19 is approximately the same size or slightly larger than the thickness of the thicker section 21 of the intermediate part 18. In addition, the transition from the thicker section 21 to the thinner section 19 can also be formed continuously or via a short wedge-shaped intermediate piece. In addition, it is entirely possible to place the support stop 5 on the thicker section 21. In the same way, this applies to the exemplary embodiment in FIG. 2. The paragraph-like transition can also take place continuously there.

Bei den Ausführungsvarianten der Fig. 6 und 8 findet, wie gesagt, ein als Kunststoff-Ummantelung ausgebildeter Stützanschlag 6 bzw. 7 Anwendung. Ausserdem ist im Falle der Fig. 6 die absatzartige Reduzierung der Messerdicke am Zwischenteil 22 vorgenommen worden, während in Fig. 8 die Dickenreduzierung am Schneidteil 23 vorgesehen ist. Demzufolge führt die Ummantelung bei Fig. 8 zu einer parziellen Verdickung des Zwischenteils 24 und zwar an seinem dem Schneidteil 23 zugeordneten Endbereich. Der Stützanschlag 6 der Fig. 6 ist dem dünneren Teilstück 25 des Zwischenteils 22 zugeordnet und so dimensioniert, dass er an der Aussenseite annähernd bündig verläuft mit dem dickeren Teilstück 26 oder dessen Aussenfläche minimal, beispielsweise um das Mass der möglichen Zusammendrückung überragt.6 and 8, as stated, a support stop 6 or 7 designed as a plastic sheath is used. In addition, in the case of FIG. 6, the step-like reduction of the knife thickness has been carried out on the intermediate part 22, while in FIG. 8 the thickness reduction is provided on the cutting part 23. Accordingly, the sheathing in FIG. 8 leads to a partial thickening of the intermediate part 24, specifically at its end region assigned to the cutting part 23. The support stop 6 of FIG. 6 is assigned to the thinner section 25 of the intermediate part 22 and is dimensioned such that it runs approximately flush on the outside with the thicker section 26 or its outer surface minimally, for example by the extent of the possible compression.
