Aus dem Stand der Technik ist bereits ein derartiges, auf den gleichen Erfinder zurückgehendes Werkzeug zum Nacharbeiten von Fugen aus dauerelastischer Fugenmasse bekannt ( EP 07118 87 B2 ). Das bekannte Werkzeug besteht aus einer im wesentlichen ebenen Platte, mit einer im wesentlichen konstanten Dicke und einem umlaufenden, beidseitig senkrecht zur Plattenebene überstehenden Rand. Die Platte hat eine im wesentlichen dreieckige Form, wobei eine der Kanten bogenförmig und zwei der Kanten gerade verlaufen. Die längere der beiden geraden Kanten und die bogenförmig verlaufende Kante schließen einen spitzen Winkel ein. In bevorzugten Ausführungsformen ist vorgesehen, dass die gerade Kante bogenförmig in die gebogene Kante übergeht bzw. dass der Eckpunkt von den die beiden einen spitzen Winkel einschließenden Längskanten ausgehend abgerundet ist. Die Stirnfläche des umlaufenden Randes verläuft ganz oder teilweise senkrecht zur Plattenebene. Eine Veränderung des Randsaums, zur Verbesserung und Erweiterung seiner Einsatzmöglichkeit als Werkzeug ist nachteiligerweise nicht vorgesehen.From the prior art, such a, going back to the same inventor tool for reworking joints of permanently elastic grout is already known ( EP 07118 87 B2 ). The known tool consists of a substantially flat plate, with a substantially constant thickness and a circumferential, on both sides perpendicular to the plane of the plate protruding edge. The plate has a substantially triangular shape with one of the edges being arcuate and two of the edges being straight. The longer of the two straight edges and the arcuate edge include an acute angle. In preferred embodiments, it is provided that the straight edge merges arcuately into the bent edge or that the corner point is rounded starting from the two edges enclosing an acute angle. The end face of the peripheral edge runs completely or partially perpendicular to the plane of the plate. A change of the rim, to Improvement and expansion of its use as a tool is disadvantageously not provided.

Aus dem Stande der Technik ( DE 10207863 , DE 20305161 , EP 1353024 , US 5075916 , DE 29817553 , DE 4312985 und DE 19847514 ) sind Werkzeuge zum Nacharbeiten und Glätten von Fugen bekannt, deren Längskanten unabhängig vom jeweiligen Verlauf als umlaufende Schnittkanten ausgebildet sind. Dabei zeigt unter anderem DE 10207863 einen Verlauf der Längskanten, welche streckenweise senkrecht zu einer Winkelhalbierenden verläuft zwischen einer geraden und einer bogenförmigen Längskante.From the prior art ( DE 10207863 . DE 20305161 . EP 1353024 . US 5075916 . DE 29817553 . DE 4312985 and DE 19847514 ) tools for reworking and smoothing joints are known, the longitudinal edges are formed independently of the respective course as circumferential cutting edges. It shows, among other things DE 10207863 a profile of the longitudinal edges, which in sections runs perpendicular to an angle bisector between a straight and an arcuate longitudinal edge.

Vor diesem Hintergrund besteht die Aufgabe der Erfindung in der Konstruktion eines Werkzeugs, das die Anbringung einer dammartigen Fugenfüllung zwischen zwei senkrecht zueinander stehenden Bauteilen ermöglicht, wobei die Arbeits- bzw. Längskanten des Werkzeugs so gestaltet sind, dass sie in Abhängigkeit vom Kantenverlauf eine variable Führung des Werkzeugs beim Anbringen der dammartigen Fugenfüllungen erlauben. Gleichzeitig sollen die mit dem Baumaterial in Verbindung kommenden Bestandteile des Werkzeugs so gestaltet sein, dass das Material zwar an der Oberfläche des Werkzeugs haftet, und dadurch überschüssiges Fugenmaterial exakt und ohne weitere Hilfsmittel abgetragen werden kann, zugleich soll die Entfernung des Materials von den Kanten des Werkzeugs nach Fertigstellung einer Fuge ohne viel Aufwand erfolgen können.Against this background, the object of the invention in the construction of a tool that allows the attachment of a dam-like joint filling between two mutually perpendicular components, wherein the working or longitudinal edges of the tool are designed so that they are variable depending on the edge profile allow the tool when attaching the dam-like joint fillings. At the same time, the components of the tool which come into contact with the building material should be designed so that the material adheres to the surface of the tool, and thus excess joint material can be removed precisely and without further aids, at the same time the removal of the material from the edges of the Tool after completion of a joint can be done without much effort.

Außerdem soll die Steifigkeit des Werkzeugs in den Baumaterialien in Verbindung kommenden Bereichen an die jeweils auftretenden mechanischen Belastungen, die auch davon abhängig sein können wie das Werkzeug angefaßt wird, angepasst sein.In addition, the rigidity of the tool in the building materials is said to be related to respective areas mechanical loads, which may also depend on how the tool is handled, adapted.

Die Lösung der Aufgabe wird erreicht durch ein Werkzeug der eingangs genannten Gattung, dass dadurch gekennzeichnet ist, dass die Platte eine zusätzliche Längskante aufweist, welche senkrecht zu der zwischen der ersten Kante und der dritten Kante liegenden Winkelhalbierenden verläuft, und dass die Stirnfläche der ersten Kante und der zusätzlichen Kante unter Bildung einer zusammenhängenden Schnittkante jeweils über die gesamte Länge nach aussen verjüngt ist, und dass die erste Kante und der angrenzende Kantenabschnitt der zweiten Kante einen Winkel von 90° einschließen.The solution of the problem is achieved by a tool of the type mentioned, characterized in that the plate has an additional longitudinal edge which is perpendicular to lying between the first edge and the third edge bisecting, and that the end face of the first edge and the additional edge is tapered outwardly along the entire length to form a continuous cut edge, and that the first edge and the adjacent edge portion of the second edge form an angle of 90 °.

Durch das Kappen einer Ecke des im wesentlichen dreieckigen Werkzeugs entsteht eine zusätzliche Kante, welche die Anbringung einer dammartigen Fuge zwischen zwei senkrecht aufeinander treffenden Bauteilen erlaubt. Der sich verjüngende Außensaum gewährleistet vorteilhafte Weise, dass das zu glättende Material und insbesondere das überflüssige, d. h. nicht in die Fuge gelangende Material vergleichsweise leicht vom Werkzeug abfällt.By capping a corner of the substantially triangular tool creates an additional edge, which attaching a dam-like joint between two perpendicular components allowed. The tapering outer seam ensures advantageous manner that the material to be smoothed and in particular the superfluous, ie not reaching into the joint material comparatively easily drops from the tool.

Der Kerngedanke der Erfindung besteht in der Schaffung einer zusätzlichen Arbeitsposition für das Werkzeug, die durch das Kappen einer Ecke erreicht wird. Unter Ausnützung der neu entstandenen Kante kann die zwischen zwei senkrecht aufeinander treffenden Bauteile zur verfüllende Fuge leicht und vor allem in gleichmäßiger Form geschlossen werden. Falls eine der von der gekappten Ecke ausgehenden Kanten geradlinig verläuft und die zweite von der gekappten Ecke ausgehenden Kante gebogen verläuft, hängt die Art der Ausbildung der dammartigen Fuge davon ab, an welcher der beiden Längskanten das Werkzeug während der Fertigung der Fuge angelegt ist. Bei den zu bearbeitenden Baumaterialien handelt es sich insbesondere um dauerelastische Fugenmassen, insbesondere Kunststoffmassen, die insbesondere aus Silikon oder Polyacryl bestehen und häufig zur Abdichtung von Kachelfugen eingesetzt werden.The essence of the invention is to provide an additional working position for the tool achieved by capping a corner. Utilizing the newly created edge, the two joints which meet perpendicularly to the filling gap can be closed easily and above all in a uniform shape. If one of the edges extending from the capped corner is rectilinear and the second edge extending from the capped corner is bent, the type of formation of the dam-like joint depends on which of the two longitudinal edges the tool is applied during fabrication of the joint. The construction materials to be processed are, in particular, permanently elastic joint compounds, in particular plastic compounds, which consist in particular of silicone or polyacrylic and are frequently used for sealing tile joints.

Es ist vorgesehen, dass die erste Kante und die dritte Kante bzw. deren geradliniger Endabschnitt, der auf die gekappte Ecke zuläuft, einen Winkel von 90° einschließen. Der Winkel der von der ersten Kante und dem geradlinigen Abschnitt der zweiten Kante eingeschlossen wird, soll 90° betragen. Bei einem rechten Winkel garantieren die beiden jeweils anliegenden Schenkel eine präzise Führung bei und zwischen senkrecht aufeinander treffenden Bauteile, zwischen denen die Fuge verläuft.It is envisaged that the first edge and the third edge or their rectilinear end portion, which tapers towards the capped corner, enclose an angle of 90 °. The angle enclosed by the first edge and the rectilinear portion of the second edge should be 90 °. At a right angle, the two adjoining legs guarantee precise guidance between and between components that strike each other perpendicularly, between which the joint runs.

Das erfindungsgemäße Werkzeug ist funktionell in zwei Hälften unterteilt, so dass vorteilhafterweise ohne kräftezehrendes Verdrehen der Hand zur Herstellung einheitlicher Fugen gearbeitet werden.The tool according to the invention is functionally divided into two halves, so that it is advantageous to work without force-consuming twisting of the hand to produce uniform joints.

In einer Weiterbildung der Erfindung ist vorgesehen, dass sich der Außensaum der bogenförmigen Abschnitte der dritten Kante zumindest in dem zur zusätzlichen Kante benachbarten Bereichen nach außen ebenfalls verjüngt. Die durch das Kappen der Ecke zusätzlich entstandene Längskante und der bogenförmige Außensaum bilden dabei eine zusammenhängende, sich nach außen hin verjüngende, Arbeitskante.In a further development of the invention, it is provided that the outer seam of the arcuate sections of the third edge also tapers outward, at least in the regions adjacent to the additional edge. The additionally formed by the caps of the corner longitudinal edge and the arcuate outer seam thereby form a contiguous, outwardly tapered, working edge.

Die dritte Kante mit einem bogenförmig verlaufenden Abschnitt kann zumindest abschnittsweise einen Bogen aufweisen, dessen Krümmungsradius von dem des Hauptbogens dieser Kante abweicht. Dabei ist denkbar, dass der auf die gekappte Ecke zulaufende Abschnitt der dritten, im wesentlichen bogenförmig verlaufenden Kante geradlinig verläuft. Dieser geradlinige Endabschnitt der dritten Kante des Werkzeugs stellt sicher, dass beim Anfertigen einer dammartigen Fuge auch im Bereich der dritten Kante eine stabile Anlage des Werkzeugs möglich ist, weil ein Verkippen des Werkzeugs verhindert wird.The third edge with an arcuate portion may at least partially have an arc whose radius of curvature differs from that of the main arc of this edge. In this case, it is conceivable that the section of the third, essentially arcuate, edge tapering towards the capped corner runs in a straight line. This rectilinear end portion of the third edge of the tool ensures that when making a dam-like joint in the region of the third edge a stable investment of the tool is possible because tilting of the tool is prevented.

Die Verlängerung des sich verjüngenden Außensaums zu einer zusammenhängenden, aus mehreren Abschnitten bestehenden Kante ist ausgehend von der sich an die zusätzliche Längskante anschließende und vollständig geradlinig verlaufenden ersten Kante möglich. Dabei ist denkbar, dass der sich an diese geradlinigen Kantenabschnitt anschließende, ebenfalls geradlinige Abschnitt, nach außen gezogen ist, d.h. der sich verjüngende Abschnitt der zweiten geradlinig verlaufenden Kante reicht in diesem Bereich über den sich nicht verjüngenden Abschnitt, hinaus. Die beiden so versetzt zueinander verlaufenden geradlinigen Teilabschnitte können durch einen geradlinigen oder bogenförmigen Abschnitt, der sich ebenfalls verjüngt, verbunden sein.The extension of the tapered outer seam to a continuous, multi-section edge is possible starting from the adjoining the additional longitudinal edge and completely rectilinear first edge. It is conceivable that the rectilinear edge portion adjoining this, also rectilinear portion, is pulled outwards, ie, the tapered portion of the second rectilinear edge extends in this area over the not rejuvenating section, out. The two rectilinear sections which are offset relative to one another can be replaced by a straight-line or arched section which likewise tapers, be connected.

Prinzipiell ist natürlich denkbar, dass sich die nach außen verjüngende Stirnfläche eines Abschnitts der zweiten insgesamt längeren geradlinigen Kanten anstatt geradlinig leicht bogenförmig verläuft. Auf diese Weise ist ein leichtes Verkippen des Werkzeuges, dass mit den beiden geradlinig verlaufenden Kanten an zwei senkrecht zueinander stehenden Bauteilen anliegt, noch möglich.In principle, of course, it is conceivable that the outwardly tapering end face of a portion of the second generally longer rectilinear edges rather than straight rectilinear arc. In this way, a slight tilting of the tool that rests with the two rectilinear edges on two mutually perpendicular components, still possible.

Die Verjüngung des Außensaums zu einer schnittartigen Arbeitskante ist zumindest in einem U-förmigen Bereich, der eine Hälfte des Werkzeuges umschließt, vorgesehen. Die komplett geradlinig verlaufende erste Kante verbindet dabei zusammen mit der im gekappten Eckbereich entstandenen zusätzlichen Längskante die beiden seitlichen Arbeitskanten.The taper of the outer seam to a cut-like working edge is provided at least in a U-shaped area enclosing one half of the tool. The completely rectilinear first edge connects the two lateral working edges together with the additional longitudinal edge formed in the capped corner area.

In einer bevorzugten Ausführungsform erstreckt sich die Verjüngung der Stirnfläche ausgehend von der Oberseite der Platte bis zur Unterseite der Platte, sodass sich eine Schnittfläche ergibt. Alternativ ist denkbar, dass sich die Verjüngung des Außensaums ausgehend von der Oberseite der Platte und der Unterseite der Platte sich bis zur Mitte der Platte erstreckt.In a preferred embodiment, the taper of the end face extending from the top of the plate to the bottom of the plate, so that there is a cut surface. Alternatively, it is conceivable that the taper of the outer seam extends from the top of the plate and the underside of the plate to the center of the plate.

Prinzipiell ist denkbar, dass die im Bereich der gekappten Ecke entstandene zusätzliche Kante geradlinig verläuft oder leicht bogenförmig aufgewölbt ist. Bei leicht bogenförmigen Verlauf wird der mit Hilfe des erfindungsgemäßen Werkzeuges zwischen zwei senkrecht zueinanderstehenden Bauteilen angefertigte Damm aus Fugenmaterial nicht geradlinig schräg, sondern nach innen gewölbt verlaufen.In principle, it is conceivable that the additional edge formed in the region of the capped corner runs in a straight line or is arched slightly arcuately. In the case of a slightly curved course, the dam made of grout material, which is produced with the aid of the tool according to the invention between two components that are perpendicular to one another, does not run straight in a straight line, but instead curves inward.

Die Enden der dritten Kante und der zweiten Kante können einen spitzen Winkel bilden oder abgerundet sein.The ends of the third edge and the second edge may form an acute angle or be rounded.

Es ist vorgesehen, dass in der Hälfte des Werkzeugs, in dem die dritte Kante und die zweite Kante spitz aufeinander zu laufen, der randständige Außensaum aus drei aneinander anschließenden Kanten besteht, wobei die beiden oben- und untenseitig liegenden Kanten parallel zueinanderverlaufen. Der Abstand der beiden Kanten voneinander begrenzt die max. Dicke der Platte. Die senkrecht zu den beiden oben- und untenseitigen Kanten entstehende dritte Kante des Außensaums begrenzt die im wesentlichen dreieckige Platte und verläuft wie bereits erwähnt abschnittsweise bogenförmig und abschnittsweise geradlinig.It is envisaged that in the half of the tool, in which the third edge and the second edge taper towards each other, the peripheral outer seam consists of three adjoining edges, wherein the two upper and lower edges parallel to each other. The distance between the two edges of each other limits the max. Thickness of the plate. The third edge of the outer seam, which is perpendicular to the two upper and lower edges, delimits the substantially triangular plate and, as already mentioned, extends in sections arcuately and in sections in a straight line.

Es ist vorgesehen, dass der vom Außensaum umrandete Mittelteil der Platte zumindest Bereichsweise bis zur Höhe der Oberseite und/oder der Unterseite des Außensaums verstärkt ist. Es ist vorgesehen, dass die Hälfte des Werkzeugs, in der die dritte Kante und die zweite Kante spitz aufeinander zu laufen, der Mittelteil der Platte die Ober- und/oder die Unterseite des Außensaums nicht überragt.It is envisaged that the center part of the plate bordered by the outer seam is reinforced, at least in regions, up to the height of the upper side and / or the lower side of the outer seam. It is envisaged that half of the tool, in which the third edge and the second edge are pointed towards one another, the central part of the plate does not project beyond the top and / or bottom of the outer seam.

Der Mittelteil des Werkzeuges und der Außensaum des Werkzeuges, der auch in den sich nach außen hin verjüngenden Bereichen die Arbeitskante des Werkzeugs bildet, aus Materialien unterschiedlicher Elastizität bestehen. Dabei kann der zum Teil bis auf die Höhe des Außensaums verstärkte Mittelbereich der Platte aus einem unelastischen Material bestehen. Infrage kommen beispielsweise Hartplastik. Der umlaufende Außensaum, der die Arbeitskante des Werkzeuges bildet besteht dagegen aus einem elastischen Kunststoff. Dabei kann es sich um ein elastisches Elastomer oder ein Thermoelastomer handeln, das weich ist und unter dem Einfluss einer anliegenden Biegekraft leicht an unterschiedliche Fugenformen anpasst.The middle part of the tool and the outer seam of the tool, which also forms the working edge of the tool in the outwardly tapering areas, consist of materials of different elasticity. In this case, the partially reinforced up to the level of the outer seam center region of the plate may consist of an inelastic material. For example, hard plastic can be considered. The circumferential outer seam, which forms the working edge of the tool, however, consists of an elastic plastic. This may be an elastic elastomer or a thermoelastomer, which is soft and easily adapted to different joint shapes under the influence of an applied bending force.

Figur 1 zeigt einen Querschnitt durch das Werkzeug, das aus einer Platte 1 besteht, die zumindest bereichsweise, hier in der rechten Hälfte 12, bis zur Höhe des Außensaums 10 verstärkt ist. Im verstärkten Bereich 12 ist der die Platte 1 außen umlaufende Außensaum 10 nach außen abgeschrägt. Die Abschrägung 11 des Außensaums 10 dient als Arbeitskante. Vorteilhafterweise setzt sich das zu verarbeitende Material an einer spitz zulaufenden Kante nicht zu leicht fest und kann deshalb besser verarbeitet werden. Der im gezeigten Beispiel auf der linken Seite liegende Außensaum 10, der sich nach außen nicht verjüngt, dient zusammen mit dem in dieser Hälfte etwas verdünnten Mittelteil als Grifffläche und ebenfalls als Arbeitskante. FIG. 1 shows a cross section through the tool, which consists of a plate 1, which is reinforced at least partially, here in the right half 12, up to the height of the outer seam 10. In the reinforced area 12 of the plate 1 outside circumferential outer seam 10 is bevelled outwardly. The bevel 11 of the outer seam 10 serves as a working edge. Advantageously, the material to be processed does not set too easily on a tapered edge and can therefore be processed better. The outer seam 10 lying on the left side in the example shown, which does not taper outwards, together with the middle part slightly thinned in this half serves as a gripping surface and likewise as a working edge.

Figur 2 zeigt das Werkzeug aus der Aufsicht. Das Werkzeug hat eine im wesentlichen dreieckige Form mit einer geradlinig verlaufenden ersten Kante 4 und einer im wesentlichen geradlinig verlaufenden zweiten Kante 5 sowie einer bogenförmig verlaufenden dritten Kante 6. Die dritte Kante 6 ist in Teilabschnitte 6b, 6c gegliedert, wobei diese Abschnitte mit abweichendem Radius aufgeweitet sind oder wie 6c geradlinig verlaufen. Die von der ersten Kante 4 ausgehende zweite Kante 5 kann in Teilabschnitte 5a, 5b, 5c unterteilt sein, wobei einer der Teilabschnitte 5c bezüglich eines anderen Teilabschnitts 5a derselben Kante nach außen gezogen ist. Im gezeigten Beispiel ergibt sich der versetzte Verlauf der Teilabschnitte 5a und 5c durch die Verjüngung des umlaufenden Außensaums 10 in der rechten Hälfte des Werkzeugs. Die geradlinigen Abschnitte 5a und 5c sind durch den im gezeigten Beispiel bogenförmig verlaufenden Teilabschnitt 5b verbunden. Der Teilabschnitt 5b kann auch geradlinig verlaufen. FIG. 2 shows the tool from the top view. The tool has a substantially triangular shape with a rectilinear first edge 4 and a substantially rectilinear second edge 5 and an arcuate third edge 6. The third edge 6 is divided into sections 6b, 6c, these sections with different radius are widened or 6c straight. The second edge 5 emanating from the first edge 4 can be subdivided into subsections 5a, 5b, 5c, one of the subsections 5c being relative to another subsection 5a the same edge is pulled outwards. In the example shown, the offset course of the sections 5a and 5c results from the tapering of the circumferential outer seam 10 in the right half of the tool. The straight sections 5a and 5c are connected by the arcuate section 5b in the example shown. The section 5b may also be straight.

Das Werkzeug weist in dem Bereich, in dem die dritte Kante 6 bzw. deren nach außen hin verjüngter Teilabschnitt 6c mit der ersten Kante 4 zusammenlaufen, eine gekappte Ecke auf. Durch das Entfernen dieser Ecke 7 entsteht eine zusätzliche Längskante 8. Der Außensaum 7 der zusätzlich entstandenen Längskante 8 ist nach außen hin ebenfalls verjüngt. Im gezeigten Beispiel bilden die Längskanten 8 und die erste Kante 4 sowie die Teilabschnitte 6b und 6c der dritten Kante 6 sowie die Teilabschnitte 5b und 5c der zweiten Kante 5 eine zusammenhängende sich nach außen verjüngende Arbeitskante.In the region in which the third edge 6 or its outwardly tapered subsection 6c converge with the first edge 4, the tool has a truncated corner. By removing this corner 7 creates an additional longitudinal edge 8. The outer seam 7 of the additionally formed longitudinal edge 8 is also tapered towards the outside. In the example shown, the longitudinal edges 8 and the first edge 4 and the subsections 6b and 6c of the third edge 6 as well as the subsections 5b and 5c of the second edge 5 form a contiguous outwardly tapered working edge.

Im gezeigten Beispiel schließt die erste Kante 4 und der geradlinig verlaufende Teilabschnitt 5c einen rechten Winkel ein. Auch der im gezeigten Beispiel geradlinige Teilabschnitt 6c, der durchaus auch als Bestandteil der dritten Kante 6 bogenförmig gestaltet sein kann, und die erste Kante 4 schließen ebenfalls einen rechten Winkel ein. Der Teilabschnitt 5c könnte ebenso wie der Teilabschnitt 6c auch leicht bogenförmig verlaufen. Der gerade Verlauf der Teilabschnitte 6c und 5c hat den Vorteil, dass bei rechtwinklig zueinander orientierten Bauteilen zusammen mit der ersten Kante 4 eine zweifach stabile Anlage des Werkzeugs an den Bauteilen möglich ist. Bei gebogenem Verlauf der Teilabschnitte 5c und 6c ist dagegen ein leichtes Verkippen des Werkzeuges beim Ansatz an die Bauteile möglich.In the example shown, the first edge 4 and the rectilinear portion 5c includes a right angle. Also, in the example shown rectilinear section 6c, which may well be designed arcuate as part of the third edge 6, and the first edge 4 also include a right angle. The subsection 5c could, like the subsection 6c, also run slightly arcuately. The straight course of the sections 6c and 5c has the advantage that in the case of components oriented at right angles to one another together with the first edge 4, a two-fold stable contact of the tool with the components is possible. In the case of curved course of the sections 5c and 6c, however, a slight tilting of the tool when approaching the components is possible.

Prinzipiell ist denkbar, dass auch die zusätzliche Längskante 8 nicht exakt geradlinig ist, sondern einen leicht bogenförmigen Verlauf aufweist. Im Falle eines bogenförmigen Verlaufs der zusätzlichen Längskante 8 ist denkbar, dass sich diese sowohl nach außen als auch nach innen wölbt. Die Form der zusätzlichen Längskante 8 bestimmt die Form der mit Hilfe des Werkzeugs bearbeiteten Fuge.In principle, it is conceivable that the additional longitudinal edge 8 is not exactly rectilinear, but has a slightly curved course. In the case of an arcuate course of the additional longitudinal edge 8 is conceivable that this bulges both outwardly and inwardly. The shape of the additional longitudinal edge 8 determines the shape of the processed using the tool joint.

Figur 3 zeigt das erfindungsgemäße Werkzeug in perspektivischer Darstellung, wobei insbesondere die Anschrägung 11 des Außensaums deutlich wird. Der auf der rechten Seite des Werkzeugs verstärkte Mittelteil kann zur Stabilisierung des Werkzeugs aus einem härteren Kunststoff bestehen. Für den umlaufenden Außensaum 10 sowie die sich nach außen hin verjüngenden Arbeitskanten, die aus den Teilabschnitten 5b, 5c sowie der ersten Kante 4 und der Längskante 8 und den Teilabschnitten 6c und 6b bestehen, ist dagegen ein weicherer Kunststoff vorgesehen. Der Kunststoff soll sich unter dem Einfluss einer anliegenden Biegekraft an die unterschiedlichen Fugenformen anpassen, so dass das zu verarbeitende Fugenmaterial unter dem Einsatz des Werkzeugs nicht auf der Oberfläche der Kacheln zurückbleibt. FIG. 3 shows the tool according to the invention in a perspective view, in particular the bevel 11 of the outer seam becomes clear. The reinforced on the right side of the tool middle part can be made to stabilize the tool of a harder plastic. For the peripheral outer seam 10 and the outwardly tapered working edges, which consist of the sections 5b, 5c and the first edge 4 and the longitudinal edge 8 and the sections 6c and 6b, however, a softer plastic is provided. The plastic should adapt to the different joint shapes under the influence of an applied bending force, so that the joint material to be processed does not remain on the surface of the tiles under the use of the tool.
