Abstract

The invention relates to an edging rail for wall or floor coverings, in particular those consisting of ceramic material, having a blade-like fastening leg (2; 102), which has a thickness of below, or anything up to, 1.5 mm, and having an edging leg (3; 103) which is thicker than the fastening leg (2; 102), the edging leg (3; 103) protruding upwards from the end of the fastening leg (2; 102) and, with its free end, defining a projection (U) towards the profile interior. For the purpose of improved bonding with the abutting mortar or adhesive, the invention proposes that the edging leg (3; 103) have a wall (3.2; 3.3; 103.2; 103.3) which is bent in the form of a ( and the outer tangent (T) of which has an angle of tau </= 90 DEG with respect to the underside of the fastening leg (2; 102) and which, at its end, defines a projection (U) - measured from the internal angle of the leg-joining region (4; 104) - of at least one wall thickness of the edging leg (3; 103). <IMAGE>

Description

Die Erfindung betrifft eine Abschlußschiene für Wand oder Bodenbeläge, insbesondere solche aus Keramikmaterial, mit einem klingenartigen, unter bzw. bis 1,5 mm starken Befestigungsschenkel, sowie mit einem Abschlußschenkel, der eine größere Dicke als der Befestigungsschenkel aufweist, wobei der Abschlußschenkel vom Ende des Befestigungsschenkels aus aufsteht und mit seinem freien Ende zum Profilinneren hin einen Überstand beschreibt.The invention relates to an end rail for wall or floor coverings, in particular those made of ceramic material, with a blade-like, under or up to 1.5 mm thick fastening leg, and with an end leg which has a greater thickness than the fastening leg, the end leg from the end of Fastening leg stands up and describes a protrusion with its free end towards the inside of the profile.

Eine solche Abschlußschiene zeigt beispielsweise die CH-PS 652 163. Das in dieser vorveröffentlichten Patentschrift dargestellte Winkelprofil dient zum Abschließen von Boden- oder Wandbelägen aus Keramikmaterial. Der Abschlußschenkel besitzt eine nach innen gerichtete, im Querschnitt etwa rechteckige Verbreiterung. Nachteilig bei der vorbekannten Schiene ist, daß das zwischen dem Abschlußschenkel, der Verbreiterung und dem Befestigungsschenkel zu liegen kommende Mörtelvolumen bei der Verlegung der keramischen Boden- und Wandbeläge nur einen relativ geringen Kontakt hat zur Innenfläche des Abschlußschenkels und überdies im Lauf der Kontaktfläche einen sehr engen Winkel zwischen der Verbreiterung und dem Abschlußschenkel ergibt, der erfahrungsgemäß zu Mörtelablösungen bei mechanischer Beanspruchung und unter Wärmebewegung führt.Such an end rail is shown, for example, in CH-PS 652 163. The angular profile shown in this previously published patent specification is used to close off floor or wall coverings made of ceramic material. The end leg has an inward widening, approximately rectangular in cross section. A disadvantage of the previously known rail is that the volume of mortar to be located between the end leg, the widening and the fastening leg has only a relatively slight contact with the inner surface of the end leg when laying the ceramic floor and wall coverings and, moreover, a very close contact in the course of the contact surface Angle between the widening and the end leg results, which experience has shown that mortar detachment under mechanical stress and under heat movement.

Es stellt sich die Aufgabe, eine Abschlußschiene für Wand- oder Bodenbeläge anzugeben, bei der die vorgenannten Nachteile nicht auftreten, insbesondere eine besonders innige Haftung des Mörtelvolumens an der Abschlußschiene beobachtet werden kann, die auch bei Beanspruchung des Überganges durch Vibrationen, Wärmebewegungen und leichte Torsionen eine signifikante Ablösung des Mörtels verhindert.It is the task of specifying an end rail for wall or floor coverings in which the aforementioned disadvantages do not occur, in particular a particularly intimate adhesion of the mortar volume to the end rail, which can also be observed when the transition is stressed by vibrations, thermal movements and slight torsions prevents a significant detachment of the mortar.

Diese Aufgabe wird gelöst bei einer Abschlußschiene, deren Abschlußschenkel eine (-förmig gekrümmte Wandung besitzt, deren Außengangente einen Winkel von τ ≦ 90° gegenüber der Außenseite des Befestigungsschenkels aufweist und der an seinem Ende einen Überstand - gemessen ab Innenwinkel der Schenkelzusammenführung - von wenigstens einer Wanddicke des Abschlußschenkels beschreibt.This object is achieved with an end rail, the end leg of which has a (-shaped wall, the outer gangue of which has an angle of τ ≦ 90 ° with respect to the outside of the fastening leg and which has at its end a protrusion - measured from the inner angle of the leg junction - of at least one Wall thickness of the end leg describes.

Demnach bildet der Abschlußschenkel keine L-förmige Konfiguration zum freien Ende hin, sondern ist gekrümmt, so daß sich die Mörtelmasse unter die Krümmung des Abschlußschenkels einschmiegen kann.Accordingly, the end leg does not form an L-shaped configuration towards the free end, but is curved, so that the mortar mass can nestle under the curvature of the end leg.

Die Breite des Überstandes ist variabel. Üblicherweise wird ein Überstand verwendet, der das 2- bis 4fache der Dicke des Abschlußschenkels beträgt. Es sei aber nicht ausgeschlossen, daß insbesondere bei großen Höhen des Abschlußschenkels ein relativ geringer Überstand und bei kleineren Abschlußschenkeln ein relativ großer Überstand gewählt wird, jeweils relativ zur Dicke des Abschlußschenkels.The width of the overhang is variable. A supernatant is usually used which is 2 to 4 times the thickness of the end leg. However, it should not be ruled out that a relatively small protrusion is selected, in particular at high heights of the end limb, and a relatively large protrusion is selected for smaller end legs, in each case relative to the thickness of the end leg.

Die Konfiguration der Krümmung des Abschlußschenkels kann beispielsweise so sein, daß der Abschlußschenkel Teil eines Mantels eines Hohlzylinders mit kreisförmiger oder elliptischer Grundfläche ist. Es kann die Kontur der Außenfläche des Abschlußschenkels auch eine Parabel sein, die ihren Ursprung im freien Ende des Abschlußschenkels hat. Andere Krümmungsformen sind ebenfalls denkbar, beispielsweise die einer Klotoide.The configuration of the curvature of the end limb can, for example, be such that the end limb is part of a jacket of a hollow cylinder with a circular or elliptical base area. It can be the contour the outer surface of the closing leg can also be a parabola, which has its origin in the free end of the closing leg. Other forms of curvature are also conceivable, for example that of a clotoid.

Die Dicke des Abschlußschenkels kann sich beispielsweise auch nach oben verjüngen; vorzugsweise sollte sie aber auf der ganzen Länge dieselbe sein.The thickness of the end leg can also taper upwards, for example; however, it should preferably be the same over the entire length.

Um einen einwandfreien und die Kanten der anliegenden Keramikplatten nicht zu stark beaufschlagenden Abschluß zu haben, sollte der Abschlußschenkel in einer planen, vertikal verlaufenden Abschlußfläche enden. Möglich ist es natürlich auch, daß die Abschlußfläche gewellt ausgebildet ist.In order to have a perfect finish and the edges of the adjoining ceramic plates are not too heavily loaded, the end leg should end in a flat, vertical end surface. Of course, it is also possible for the end face to be corrugated.

Es sei auch nicht ausgeschlossen, daß eine gewisse Materialverdickung am Ende des Abschlußschenkels vorgesehen wird, beispielsweise eine I-, L- oder T-Konfiguration, die jedoch so geringe Ausmaße hat, daß das eingangs genannte Einschmiegen des Mörtels nicht gestört wird.It should also not be ruled out that a certain material thickening is provided at the end of the end leg, for example an I, L or T configuration, which, however, is so small that the nesting of the mortar mentioned at the beginning is not disturbed.

Besonders vorteilhaft ist es, die Innenfläche des Abschlußschenkels und/oder die Außenfläche des Befestigungsschenkels mit haftungserhöhenden Strukturen, beispielsweise Riefen in einer Höhe von 0,1 bis 0,5 mm, zu versehen.It is particularly advantageous to provide the inner surface of the end leg and / or the outer surface of the fastening leg with structures that increase adhesion, for example grooves with a height of 0.1 to 0.5 mm.

Um eine weitere Verbesserung der Verankerung zu erreichen, wird vorstehend von der Innenseite des Abschlußschenkels und parallel zur Oberseite des Befestigungsschenkels ein Haltesteg vorgesehen, der auch in einer Verdickung, vorzugsweise in einer L- oder T-Konfiguration, enden kann. Dieser Haltesteg sollte denselben oder einen etwas geringeren Überstand aufweisen als der Abschlußschenkel.In order to achieve a further improvement in the anchoring, a retaining web is provided above from the inside of the end leg and parallel to the top of the fastening leg, which can also end in a thickening, preferably in an L or T configuration. This retaining web should have the same or a slightly less protrusion than the end leg.

Die Abschlußschiene wird vorzugsweise aus Hart-PVC hergestellt. Es sei aber nicht ausgeschlossen, daß auch Metalle, vorzugsweise Messing, Verwendung finden.The end rail is preferably made of hard PVC. However, it should not be excluded that metals, preferably brass, are also used.

Wie an sich bekannt, sollte der Befestigungsschenkel auch mit Durchbrechungen versehen sein.As is known per se, the fastening leg should also be provided with openings.

Der eingangs genannte Begriff "klingenartig" bezieht sich darauf, daß der Befestigungsschenkel unterhalb einer Keramikfliese bei Dünnbettverlegung verlegt werden soll. Es hat sich gezeigt, daß der Schenkel daher ca. 1,5 mm dick sein sollte. Er kann auch zum freien Ende hin sich verjüngen und damit eine verbesserte Festigkeit unter Materialersparnis erzielen lassen.The term “blade-like” mentioned at the outset relates to the fact that the fastening leg is to be laid below a ceramic tile when laying thin beds. It has been shown that the leg should therefore be approximately 1.5 mm thick. It can also taper towards the free end and thus achieve improved strength while saving material.

Figur 1 zeigt eine gegenüber üblichen Ausführungen vergrößerte Darstellung einer Abschlußschiene 1. Übliche Höhen der Schienen entsprechen den Aufbauhöhen der Bodenbeläge; realistische Höhen sind daher 8, 10 oder 12 mm und dergleichen. Die abgebildete Abschlußschiene 1 weist einen klingenartigen, d.h. relativ dünnen und langen Befestigungsschenkel 2 auf. Der Befestigungsschenkel 2 verjüngt sich von der Schenkelzusammenführung 4 zu seinem freien Ende hin. Auch an der dicksten Stelle ist seine Dicke gleich oder weniger als 1,5 mm.FIG. 1 shows an enlarged representation of an end rail 1 compared to conventional designs. Usual heights of the rails correspond to the construction heights of the floor coverings; realistic heights are therefore 8, 10 or 12 mm and the like. The illustrated end rail 1 has a blade-like, i.e. relatively thin and long mounting leg 2. The fastening leg 2 tapers from the leg junction 4 to its free end. Even at the thickest point, its thickness is equal to or less than 1.5 mm.

Der Befestigungsschenkel ist mit Durchbrechungen 7 versehen, die dazu dienen, das Durchtreten von Mörtel oder Kleber bei der Verlegung zu verbessern.The fastening leg is provided with openings 7, which serve to improve the passage of mortar or adhesive when laying.

Weiterhin ist ein Abschlußschenkel 3 vorhanden, der einstückig mit dem Befestigungsschenkel, beispielsweise als Strangpreßprofil aus Hart-PVC, hergestellt ist. Der Abschlußschenkel 3 weist eine größere Dicke als der Befestigungsschenkel 2 auf, wobei der Abschlußschenkel 3 vom Ende des Befestigungsschenkels 1 aus aufsteht und mit seinem freien Ende zum Profilinneren hin einen Oberstand U beschreibt.Furthermore, an end leg 3 is provided, which is made in one piece with the fastening leg, for example as an extruded profile made of hard PVC. The end leg 3 has a greater thickness than the fastening leg 2, the end leg 3 rising from the end of the fastening leg 1 and with its free end toward the inside of the profile describing an overhang U.

Der Abschlußschenkel 3 besitzt eine (-förmig gekrümmte Außenwandung 3.2 und eine parallel dazu gekrümmte Innenwandung 3.3. Die Außentangente T an der Außenwandung 3.2 hat zunächst einen Winkel I von 90° gegenüber der Außenseite 2.1 des Befestigungsschenkels. Wandert die Tangente weiter nach oben, so wird der Winkel I immer kleiner, bis er zum Schluß sogar gegen 0° geht, d.h. am Ende befindet sich eine waagerecht auslaufende Scheitelfläche 3.4. Der Überstand U, gemessen ab Innenwinkel der Schenkelzusammenführung 4, beträgt im vorliegenden Falle etwa das Dreifache der Dicke des Abschlußschenkels. Der Abschlußschenkel endet in einer planen, vertikal verlaufenden Abschlußfläche 3.5. Im vorgenannten Ausführungsbeispiel endet der Abschlußschenkel ohne eine weitere Verdickung an seinem Ende. Es soll aber nicht ausgeschlossen werden, daß hier aus optischen oder Gründen der Stabilität noch eine Verdickung vorgesehen ist, beispielsweise in einer L- oder T-Konfiguration.The end leg 3 has a (-shaped outer wall 3.2 and a parallel parallel inner wall 3.3. The outer tangent T on the outer wall 3.2 initially has an angle I of 90 ° with respect to the outer side 2.1 of the fastening leg. If the tangent moves further upwards, then the angle I becomes smaller and smaller until it even approaches 0 ° at the end, ie at the end there is a horizontally tapering apex surface 3.4. The final leg ends in a flat, vertical end surface 3.5. In the aforementioned embodiment, the end leg ends without further thickening at its end. However, it should not be excluded that a thickening is provided here for optical or reasons of stability, for example in an L or T configuration.

Besonders vorteilhaft ist es, Riefen mit einer Höhe von 0,1 bis 0,5 mm und einer Breite von etwa 0,2 mm mit entsprechenden Abständen (vgl. Figur 1) vorzusehen, die als haftungserhöhende Strukturen an der Innenwandung 3.3 des Abschlußschenkels und/oder an der Unterseite 2.1 des Befestigungsschenkels 2 angeordnet sind.It is particularly advantageous to provide grooves with a height of 0.1 to 0.5 mm and a width of about 0.2 mm with corresponding spacings (cf. FIG. 1), which as adhesion-increasing structures on the inner wall 3.3 of the end leg and / or are arranged on the underside 2.1 of the fastening leg 2.

Als weiteres wesentliches Element zur Erhöhung der Einbettungsqualität der Abschlußschiene wird ein von der Innenwandung des Abschlußschenkels und parallel zur Überseite des Befestigungsschenkels vorstehender Haltesteg 6 vorgesehen. Der Haltesteg besitzt eine T-förmige Endverdickung 6.1. Wie erkennbar, weist der Haltesteg 6 einen etwas geringeren Überstand auf als der Abschlußschenkel 3. Hierdurch ergibt sich eine dickere Mörtelschicht zwischen der Außenkante eine Bodenbelagelementes 10, (z.B. Fliese) und dem Haltesteg (vgl. Figur 3).As a further essential element for increasing the embedding quality of the end rail, a retaining web 6 projecting from the inner wall of the end leg and parallel to the upper side of the fastening leg is provided. The retaining web has a T-shaped end thickening 6.1. As can be seen, the retaining web 6 has a somewhat smaller projection than the end leg 3. This results in a thicker layer of mortar between the outer edge of a floor covering element 10 (e.g. tile) and the retaining web (see FIG. 3).

Als Material für die Abschlußschiene eignet sich Hart-PVC, andere Kunststoffe, evtl. glasfaserverstärkte Kunststoffe, aber auch Metalle, vorzugsweise Messing. Im Prinzip können alle Werkstoffe verwendet werden, die zur Herstellung derartiger Abschlußschienen bereits bekannt sind.Hard PVC, other plastics, possibly glass fiber reinforced plastics, but also metals, preferably brass, are suitable as the material for the end rail. In principle, all materials can be used that are already known for the production of such end rails.

In Draufsicht zeigt Figur 2 die Abschlußschiene. Es ist erkennbar, daß der Abschlußschenkel 3 relativ weit zum Profilinneren übersteht.Figure 2 shows the top rail in plan view. It can be seen that the end leg 3 protrudes relatively far to the inside of the profile.

Figur 3 zeigt eine typische Verlegesituation. Ein Bodenbelagselement, hier eine Fliese 10, ist in Mörtel 11 eingebettet. Im durch Wärmebewegungen und Krafteinleitungen beanspruchten Bereich in der Nähe der Abschlußfläche 3.5 ist nur eine relativ dünne Schicht zwischen der Kante der Fliese 10 und der Abschlußfläche vorgesehen. Den unter dem Überstand des Abschlußschenkels liegenden Hohlraum füllt eine relativ große Mörtelmenge aus, in die der Haltesteg 6 verankert eingebettet ist.Figure 3 shows a typical laying situation. A floor covering element, here a tile 10, is embedded in mortar 11. In the area in the vicinity of the end face 3.5, which is stressed by thermal movements and the introduction of force, only a relatively thin layer is provided between the edge of the tile 10 and the end face. A relatively large amount of mortar fills the cavity lying under the overhang of the end limb, in which the retaining web 6 is embedded anchored.

In Figur 4 ist eine Abschlußschiene 101 dargestellt. Sie besteht aus einem Befestigungsschenkel 102, der in einen Abschlußschenkel 103 übergeht. Der Befestigungsschenkel 102 verjüngt sich vom Abschlußschenkel 103 gesehen zu seinem freien Ende hin. Er hat eine Länge von etwa 20 bis 25 mm im Verhältnis zu einer Höhe zwischen 6 und 15 mm des Abschlußschenkels 103. Die Höhe des Abschlußschenkels 103 wird konkret durch die jeweilige Aufbauhöhe der Bodenbeläge bestimmt.In Figure 4, an end rail 101 is shown. It consists of a fastening leg 102 which merges into a closing leg 103. The fastening leg 102 tapers as seen from the end leg 103 towards its free end. It has a length of approximately 20 to 25 mm in relation to a height of between 6 and 15 mm of the end leg 103. The height of the end leg 103 is specifically determined by the respective height of the floor coverings.

Der Abschlußschenkel 103 besitzt eine (-förmig gekrümmte Außenwandung 103.2. Die Außentangente der Außenwandung 103.2 hat am Befestigungsschenkel 102 einen Winkel von 90° gegenüber einer Außenseite 102.1 des Befestigungsschenkels 102. Je weiter die Außentangente T zu einer Scheitelfläche 103.4 des Abschlußschenkels 103 wandert, um so kleiner wird der Winkel τ, der am Schluß sogar gegen Null gehen kann. In Figur 4 neigt sich nach einem relativ großen Winkel τ die Außenwandung 103.2 in eine waagerecht auslaufende Scheitelfläche 103.4. Die Scheitelfläche 103.4 ist damit eine plane, im wesentlichen parallel zur Unterseite 102.1 des Befestigungsschenkels 102 liegende Fläche. Ihr schließt sich eine gewellte, vertikal verlaufende Abschlußfläche 103.5 an, in die der Abschlußschenkel 103 endet. Parallel zur Außenwandung 103.2 verläuft eine Innenwandung 103.3. Etwa in der Mitte der Innenwandung 103.3 ist ein Haltesteg 106 angeordnet, der in eine gerundete Verdickung übergeht. Selbstverständlich ist es auch möglich, daß die Seitenflächen des Haltestegs 106 parallel zueinander verlaufen und mit einer Halb- oder Teilrundung nach vorne hin abschließen. Die freie Innenwandung 103.3 trägt auf ihrer freien Fläche Riefen 105.2.The end limb 103 has a (-shaped outer wall 103.2. The outer tangent of the outer wall 103.2 has an angle of 90 ° on the fastening leg 102 with respect to an outer side 102.1 of the fastening leg 102. The further the outer tangent T migrates to an apex surface 103.4 of the end leg 103, the more 4, the outer wall 103.2 tilts into a horizontally tapering apex surface 103.4 after a relatively large angle τ. The apex surface 103.4 is thus a flat, essentially parallel to the underside 102.1 surface of the fastening leg 102. This is followed by a corrugated, vertically running end surface 103.5, into which the end leg 103 ends, and an inner wall 103.3 runs parallel to the outer wall 103.2 A holding web 106 is arranged in the middle of the inner wall 103.3 and merges into a rounded thickening. Of course, it is also possible for the side surfaces of the holding web 106 to run parallel to one another and to end with a half or partial rounding toward the front. The free inner wall 103.3 has grooves 105.2 on its free surface.

Der Befestigungsschenkel 102 ist mit Durchbrechungen 107 versehen. Sie dienen dazu, das Durchtreten von Befestigungsmittel in Form von Mörtel, Kleber oder dergleichen zu ermöglichen, um so ein Verlegen zu erleichtern und ein Halten der Abschlußschiene zu gewährleisten. Um das Haften am Untergrund darüber hinaus zu verbessern, ist der Befestigungsschenkel 102 an seiner Unterseite 102.1 mit Riefen 105.1 versehen.The fastening leg 102 is provided with openings 107. They serve to allow the passage of fasteners in the form of mortar, adhesive or the like, in order to facilitate laying and to ensure that the end rail is held. In order to further improve the adhesion to the subsurface, the fastening leg 102 is provided with grooves 105.1 on its underside 102.1.

Liegt die Abschlußschiene 101 mit der Unterseite 102.1 des Befestigungsschenkels 102 auf einer geraden Fläche, hat der Befestigungsschenkel 102 im Bereich einer Schenkelzusammenführung 104 etwa den gleichen Querschnitt wie der sich daran anschließende Befestigungsschenkel 103. Die Schenkelzusammenführung 104 kann dabei eckig oder gerundet ausgebildet sein. Ist die Schenkelzusammenführung 104 gerundet ausgebildet, geht diese Rundung über in die gerundet ausgebildete Riefe 102, um dann über eine parallel zur Außenwandung verlaufenden Teilfläche der Innenwandung 103 abgerundet in den Haltesteg 106 überzugehen. Die gegenüberliegende Fläche des Haltestegs 106 mündet ebenfalls gerundet in die nächste gerade Fläche der Innenwandung 103. Der Bereich zwischen der verbleibenden geraden Innenwandung 103 und dem sich daran anschließenden Bereich der gewellten Abschlußfläche ist gleichfalls mit einer Hohlkehle versehen. Selbstverständlich ist es auch möglich, daß sämtliche Rundungen ein- oder mehreckig ausgebildet sind.If the end rail 101 with the underside 102.1 of the fastening leg 102 lies on a straight surface, the fastening leg 102 in the area of a leg merging 104 has approximately the same cross section as the adjoining fastening leg 103. The leg merging 104 can be angular or rounded. If the leg merging 104 is rounded, this rounding merges into the rounded groove 102 in order to then merge into the retaining web 106 via a partial surface of the inner wall 103 that runs parallel to the outer wall. The opposite surface of the retaining web 106 likewise ends in a rounded manner in the next straight surface of the inner wall 103. The region between the remaining straight inner wall 103 and the adjoining region of the corrugated end surface is likewise provided with a fillet. Of course, it is also possible that all curves are single or polygonal.

Wie insbesondere aus Figur 6 ersichtlich ist, ermöglicht der nach vorn geneigte Überstand U und die besondere Ausgestaltung der Innenwandung 103.3 des Abschlußschenkels 103 das Eindringen von Mörtel 111 in den freien Bereich zur Kante einer Fliese 110. Dadurch, wie auch aus Figur 5 ersichtlich, daß der Überstand U des Abschlußschenkels 103 sich weit über den Befestigungsschenkel 102 neigt, wird hier ein Bereich hoher Haftfestigkeit geschaffen. Für eine gute Haftfestigkeit sorgt darüber hinaus die gewellt ausgebildete Abschlußfläche 103.5. Es ist gewährleistet, daß zum einen die Abschlußfläche 103.5 sehr eng an der Fliese 110 anliegen und zum anderen so viel Mörtel aufgenommen werden kann, daß eine vollkommen sichere Haftung vorhanden ist. Mit der planen Scheitelfläche 103.4 ist darüber hinaus ein bündiger Abschluß mit der äußeren Oberfläche der Fliese 110 gegeben. Dadurch, daß die Abschlußschiene 101 durch ihre besondere Ausbildung innig das Befestigungsmittel z. B. in Form von Mörtel 111 integriert, trennt sich die Innenwandung 103.3 bzw. die Unterseite 102.1 mit ihren Durchbrechungen 107 nicht glatt vom Mörtel 111, sondern beansprucht diesen vielmehr so stark, daß er in sich zerreißt. Dadurch wird die Haftfähigkeit der gesamten Abschlußschiene 101 gegenüber der Fliese 110 durch die Festigungseigenschaften des Befestigungselements, z.B. in Form von Mörtel 111 oder dergleichen, bestimmt.As can be seen in particular from FIG. 6, the forward protruding projection U and the special design of the inner wall 103.3 of the end leg 103 allow mortar 111 to penetrate into the free area towards the edge of a tile 110. As can also be seen from FIG. 5, the protrusion U of the end leg 103 tilts far beyond the fastening leg 102, an area of high adhesive strength is created here. The corrugated end surface 103.5 also ensures good adhesive strength. It is ensured that, on the one hand, the end surface 103.5 lies very closely against the tile 110 and, on the other hand, so much mortar can be absorbed that there is completely reliable adhesion. With the flat apex 103.4 there is also a flush seal with the outer surface of the tile 110. The fact that the end rail 101 intimately the fastener z. B. integrated in the form of mortar 111, the inner wall 103.3 or the underside 102.1 with its openings 107 does not separate smoothly from the mortar 111, but rather strains it so much that it tears apart. As a result, the adhesiveness of the entire end rail 101 to the tile 110 is determined by the fastening properties of the fastening element, e.g. in the form of mortar 111 or the like.

Eine Abschlußschiene 101 der beschriebenen Ausführungsform ist im Prinzip aus allen Werkstoffen herstellbar, die für derartige Abschlußschienen denkbar sind. Insbesondere eignen sich Hart-PVC, andere Kunststoffe, glasfaserverstärkte Kunststoffe, Metalle, vorzugsweise Messing, Stahl und dergleichen.A closure rail 101 of the described embodiment can in principle be produced from all materials that are conceivable for such closure rails. Hard PVC, other plastics, glass fiber reinforced plastics, metals, preferably brass, steel and the like are particularly suitable.
