Description

The present invention relates to an elongated tile closure profile which, viewed in cross-section, comprises a mounting leg defining a support surface and provided with passage openings for fixing to a substrate and a boundary limb adjoining it substantially perpendicularly, whose outside defines a visible surface.

Tile finishing profiles of the type mentioned are used to complete laid in thin-bed mortar tile coverings on the floor finish or in the joint area matching tile coverings. They form an optical finish of the tile coverings. In addition, they protect the front sides of the tiles from damage. The term "tiles" is understood in the context of the present application as a generic term for plate-shaped covering material made of ceramic, natural stone or artificial stone. The term "thin bed mortar" defines any type of adhesive and / or tile adhesive with which tiles can be laid using the so-called thin bed process.

When laying a tile finish profile, the attachment leg between a tile and the substrate is normally embedded in a thin bed mortar used to secure the tile, the thin bed mortar penetrating the through holes of the attachment leg. In this way, the tile closure profile is held securely to the substrate after curing of the thin-bed mortar. The boundary leg, whose width is adapted to the thickness of the tiles, is thereby positioned such that between this and the end faces the adjacent tiles a joint of desired width remains, which can be filled with grout later.

A tile finishing profile made as an extruded profile of the type mentioned above, which consists exclusively of a fastening leg and a limiting leg with different thicknesses, is sold, for example, by Schlüter-Systems KG under the product name Schlüter-SCHIENE-V.

Furthermore, tile closure profiles are known which, in addition to a fastening leg and a limiting leg, have a tail limb directly adjoining the limb limb and defining a free end of the tile end profile, which extends substantially perpendicularly to the limiter limb. Such end legs serve to cause an optical broadening compared to the other material thickness of the tile closure profile. Examples include the tile closing profiles sold by Schlüter-Systems KG under the product name Schlüter-SCHIENE-AE, which are also designed as extruded profiles.

In tile finishing profiles, which are made by roll profiling or folding of a metal strip of constant thickness, it is also known to achieve an optical broadening of the type described above by the free end of the limiting leg is bent to form a tail limb by 180 °, resulting in a compared to the other material thickness of the metal strip results in wider bending edge. Such a variant is marketed by Schlüter-Systems KG under the product name Schlüter-SCHIENE-E.

Furthermore, tile closure profiles are known, which in addition to a fastening leg and a limiting leg have a joint web, which projects from a central region of the limiting leg and is brought into abutment with the front side of the adjacent tile during installation. The main advantage of such a joint web is that a uniform joint width can be adjusted in a simple manner. In addition, an undercut chamber is formed to clamp the grout. For example, Schlüter-SCHIENE-AE Schlüter-Systems KG is again referenced in this context.

Based on this prior art, it is an object of the present invention to provide a tile closure profile of the type mentioned with alternative and stable structure that can be easily installed and flexibly finished.

To achieve this object, the present invention provides a tile closure profile of the type mentioned, which is characterized in that a directly adjoining the boundary leg, extending downwards in the direction of the attachment leg stop leg is provided, wherein the stop leg with the boundary leg an angle in the area between 5 and 30 ° and has a plurality of through holes. The main advantage of such a stop leg is that can be set with this analogous to a joint web of the type described above on the upper face a uniform joint width, if this is brought in the laying of the tile finishing profile with the front side of the adjacent tiles in abutment. In addition, the boundary leg is visually broadened by the crimping of the stop leg and additionally stabilized. To ensure that grout despite the by the inventive Arrangement of the stop leg reduced grout receiving space in the laying of the tile finishing profile can be safely and permanently placed between this and the adjacent tiles, the stop leg is provided with through holes in which the grout can dig.

According to one embodiment of the present invention, the tile closure profile is made in one piece.

Preferably, it is bent from a metal strip, wherein the metal strip is made in particular of stainless steel, brass or aluminum and / or has a uniform material thickness of 0.4 to 1.2 mm, better still from 0.5 to 0.8 mm.

According to a variant of the present invention, a closing leg adjoins the stop leg, which defines a free end of the tile closure profile and extends in the direction of the limiting leg. In this way, a joint chamber defined size is formed between the limiting leg, the stop leg and the end leg, in which the grout penetrating through the through holes of the stop leg is added.

Advantageously, the stop leg and the end leg extend substantially parallel to each other at a distance in the range between 0.5 and 2 mm, whereby a joint chamber of optimized size is formed. Alternatively, the distance between the stop leg and the end leg may increase in a wedge shape. Also, the stop leg and the end leg can fit tightly against each other, in which case only the through holes form an undercut for the cementing of the joint mortar.

The boundary limb of the tile closure profile according to the invention may have a visually appealing arcuate curve extending over substantially 90 °.

Alternatively, however, the limiting leg can also be L-shaped, if an angular design is preferred. Likewise, fundamentally differently shaped limiter legs are possible for optical or application reasons.

According to one embodiment of the present invention, the fastening leg and the limiting leg are connected to one another via a connecting leg, which forms an angle between 3 and 20 ° with the fastening leg, in particular an angle between 5 and 15 °, and is provided with a plurality of through holes. Such, provided with through holes connecting leg also forms a joint of defined size when laying in the area of outer corners, in which the grout is safely and permanently absorbed due to the through holes.

Furthermore, the present invention provides a tile closure profile, in particular of the type described above, which, viewed in cross-section, comprises a fastening leg provided with through holes for attachment to a substrate and a boundary limb adjoining it substantially perpendicularly, whose outside defines a visible surface, wherein the Mounting leg is provided with at least one longitudinally extending stiffening bead which protrudes in the direction of the limiting leg. The formation of the fastening leg with such a stiffening bead is advantageous in that it prevents accidental bending of the tile closure profile counteracts during its storage, transport or handling.

Preferably, each bead extends over the entire length of the attachment leg, whereby a very stable arrangement is achieved while still simple design.

Alternatively, a plurality of stiffening beads extending in the longitudinal direction and parallel to one another are provided over the entire length of the fastening leg.

Advantageously, the at least one bead has a depth which substantially corresponds to the material thickness of the fastening leg.

The Figures 1 and 2 show a tile closure profile 1 according to a first embodiment of the present invention, which is used to complete a tiling or in corner areas hitting tile coverings along the exposed end faces of the tiles, as described below with reference to the FIGS. 3 and 4 is explained in more detail. In the present case, the tile end profile 1 is bent in one piece from an elongated metal strip, the metal strip being produced in particular from stainless steel, brass or aluminum and having a uniform material thickness of 0.4 to 1.2 mm, in particular from 0.5 to 0.8 mm. Viewed in cross-section, the tile closure profile 1 comprises a lower supporting surface 2 defining and provided with through holes 3 mounting leg 4, which is used for fixing to a substrate, to this immediately and substantially perpendicular subsequent boundary leg 5, whose width B to a thickness S. laying tiles 6 is adapted and the outer side 7 defines a visible surface, and a directly adjoining the boundary leg 5, downwardly extending in the direction of the mounting leg 4 stop leg 8, which forms an angle α with the boundary leg 5 in the range between 5 and 30 ° , The stopper leg 8 is provided with a plurality of through holes 9 which are formed in the present case in the longitudinal direction L in a uniform distribution. The through holes 3 of the fixing leg 4 and the through holes 9 of the stopper leg 8 are normally punched before the metal strip is bent into shape.

FIG. 3 shows the tile closure profile 1 in a first installation state in which the tile end profile 1 was used to complete a flat covering of tiles 6. For the production of in FIG. 3 As shown in a first step, the tile closure profile 1 using a thin-bed mortar 11 is positioned on the substrate 10 such that the end faces 12 of the adjacent row to be completed tile 6 abut the stop leg 8 of the tile end profile 1, whereby between these end faces 12 and the stop leg 8 a is formed upwardly wedge-shaped widening joint space. The thin-bed mortar penetrates the passage openings 3 of the fastening leg 4, so that the tile end profile 1 is securely held on the substrate 10 after the thin-bed mortar 11 has hardened. In a further step, the joint space is filled from above with a joint mortar 13, which penetrates through the through holes 9 of the stop leg 8 and clamps accordingly, so that the grout mortar 13 is firmly connected after its curing with the stop leg 8 of the tile end profile 1.

A significant advantage of the tile closure profile 1 is that it has a very simple structure, which is produced in particular by bending a metal strip and thus inexpensive, the metal strip already have the desired Oberflächenfinish the visible outer side 7 of the limiting leg 5 and the through holes 3 and 9 can. The stop leg 8 assumes the function of a joint web, which ensures a simple and uniform adjustment of the joint width of the joint mortar 13 to be filled gap. At the same time, thanks to the clearance holes 9 provided in the stop leg 8, it is ensured that the grout 13 can be securely anchored despite the comparatively small joint size.

FIG. 4 shows the tile end profile 1 in a further installation state in which the tile end profile 1 was used to complete each other meeting tile coverings along the exposed end faces of the outer rows of tiles 6 defined in the corner tiles. In the FIG. 4 The arrangement shown is made by first attaching the vertically extending tiles 6 to the associated substrate 10 using thin bed mortar 11. Then, a thin-bed mortar is applied to the exposed end faces 12 of the already laid tiles 6 and on the horizontal substrate 10. In a further step, the fastening leg 4 of the tile closure profile 1 is pressed into the thin-bed mortar 11 and aligned with the already laid tiles 6. Subsequently, the horizontally extending tiles 6 are then laid in the already applied thin-bed mortar 11, wherein the end faces 12 of facing the tile closure profile 1 tiles 6 are positioned so that they touch the stop leg 8 of the tile end profile 1. In order to be able to introduce joint grout 13 between the fastening leg 4 and the covered end faces 12 of the tiles 6, the joint space of thin-bed mortar must be kept free. In a last step, in the manner described above, the remaining between the tiles 6 and the tile closure profile 1 joints are filled with joint mortar 13, which in turn penetrates the through holes 9 of the stop leg 8.

The FIGS. 5 and 6 show a tile closure profile 1 according to a second embodiment of the present invention, which has substantially the same structure as that in the FIGS. 1 to 4 has shown tile closure profile 1. A first difference is that the fastening leg 4 and the limiting leg 5 do not directly merge into one another but are connected to one another via a connecting leg 14, which forms an angle with the fastening leg 4 β between 3 and 20 °, in particular an angle between 5 and 15 °, wherein the connecting leg 14 is provided with a plurality of through holes 9, which are arranged distributed in the longitudinal direction L substantially uniformly over the connecting leg 14. In addition, there is another difference in that the fastening leg 4 is provided with a stiffening bead 15 extending in the longitudinal direction L, which projects upwards in the direction of the limiting leg 5 and in the present case extends over the entire length of the fastening leg 4. In the present case, the stiffening bead 15 has a depth t that essentially corresponds to the material thickness of the fastening leg 4.

The stiffening bead 15 is advantageous in that accidental bending of the tile finishing profile 1 during its storage, transport or handling is made more difficult. Accordingly, it is less likely to damage the tile closure profile 1. The advantage of the connecting leg 14 comes into play when the tile closure profile 1 is laid in a corner area, as in FIG. 7 is shown. The connecting leg 14 defines a further joint in an optically desired viewing width between the tile end profile 1 and the presently vertically arranged tiles 6, which is filled with joint mortar 13, which in turn penetrates the through holes 9 of the connecting leg 14 and digs into the connecting leg 14.

The FIGS. 8 and 9 show a tile closure profile 1 according to a third embodiment of the present invention, which differs from the tile closure profile 1 according to the second embodiment in that adjoining the stop leg 8 is a closing leg 16 which defines a free end of the curved tile closure profile 1. The end leg 16 extends in the direction of the limiting leg 5. It is presently bent starting from the stop leg 8 by 180 ° inwards and extends parallel to this at a distance of at least 1.5 mm. The advantage of such a tail leg 16 is that this defines together with the stop leg 8 Fugenmörtelaufnahmeraum, which limits the amount of male grout 13 aufzunehmendem and thereby favors the anchoring of the through holes 9 of the stop leg 8 penetrating joint mortar 13. This is off FIG. 10 seen. The joint space can also be wedge-shaped by the angle is selected slightly smaller or larger than 180 °. The end leg 16 can also lie flat against the rear side of the stop leg 8. In this case, only the perforations 9 remain for the purpose of clamping the joint mortar 13.

FIG. 11 shows a tile closure profile 1 according to a fourth embodiment of the present invention, which differs from the third embodiment in that the limiting leg 5 has a substantially arcuate curve extending over substantially 90 °. A possible installation state of such a tile closure profile 1 shows FIG. 12 ,

FIG. 13 shows a tile closure profile 1 according to a fifth embodiment of the present invention, which differs from the third embodiment in that the limiting leg 5 is L-shaped. A possible installation state of such a tile closure profile 1 shows FIG. 14 ,

It should be understood that the above-described embodiments of tile closure profiles 1 according to the invention are not to be understood as limiting. Rather, modifications and changes are possible without departing from the scope of the present application, by the attached Claims is defined. Above all, the connection leg 5 may have different contours due to the application than shown. As essential is always to consider the formation of the joint for receiving the grout.
