DETAILED DESCRIPTION

[0092] FIG. 1 shows a portion of a decoupling sheet 1 in accordance with the invention with a carrier plate 2 and a plurality of nubs 4 protruding from the carrier plate plane 3. Adjacent nubs 4 are arranged transversely to the lengthwise direction 5 (in the transverse direction 15) of the carrier plate 2 and in the lengthwise direction 5 of the carrier plate 2. Furthermore, FIG. 1 illustrates that immediately adjacent nubs 4 transversely to the lengthwise direction 5 (in the transverse direction 15) and in the lengthwise direction 5 of the carrier plate 2 have a triaxial nub base 10.

[0093] The triaxial formation of the nub 4 and/or the nub base 10 means that three legs 12, 13 are provided. The triaxial formation of the nub base 10 is evident in the top view looking down on the decoupling sheet 1 and hence in a top view looking down on the nub 4.

[0094] The immediate proximity of the nubs 4 in the lengthwise direction 5 and in the transverse direction 15 occurs in the case of a group of at least three nubs 4. This means that at least three immediately adjacent nubs 4 comprise a triaxially shaped nub base 10 in the lengthwise direction 5 and in the transverse direction 15. In the arrangement of the nubs 4 on the carrier plate 2 it is provided that the nubs 4 and the nub bases 10 neither intersect nor overlap. In the end, it is understood that in an embodiment of the decoupling sheet 1 according to the invention (not shown), it may be provided that different nub shapes and/or forms of the nub base 10both triaxial and any given shapesmay be used on the decoupling sheet 1. In this variant embodiment (not shown), however, a group of at least three immediately adjacent nubs 4 with a triaxial nub base 10 is formed.

[0095] Alternatively and/or additionally to the triaxial formation of immediately adjacent nubs 4 in the lengthwise direction 5 and in the transverse direction 15, it is provided that on the decoupling sheet 1 at least one nub 4 having a triaxial nub base 10 with three long sides 6a is present. FIGS. 3 and 4 show that the middle region 7 of the nub 4 and/or the nub base 10 is defined by a circle which all the long sides 6 contact tangentially.

[0096] FIGS. 3 and 4 show various embodiments of the triaxial nub shape with different triaxial nub bases 10 having three long sides 6a.

[0097] Moreover, FIG. 1 shows the arrangement of the nubs 4 per FIG. 4 on a decoupling sheet 1, wherein all the nubs 4 have a triaxial nub base 10.

[0098] In a variant embodiment (not shown), only one nub shape having a triaxial nub base 10 with three long sides 6a per FIG. 3 or 4 is provided, which is placed in a carrier plate 2, wherein the other nubs 4 have familiar nub structures, for example cylindrical and/or pot-shaped.

[0099] Moreover, FIGS. 3 and 4 show that the long side 6 of the nub 4 and/or the nub base 10 is concave. In a variant embodiment (not shown), only one long side 6a of the nub 4 or two long sides 6a of the nub 4 are concave.

[0100] A nub interior space 20 is formed by the nub base 10 and at least one side wall adjoining the nub base 10, wherein the at least one side wall produces the three-dimensional shape of the nub 4.

[0101] FIG. 2 shows that in the exemplary embodiment illustrated, an undercut 8 is present at the nub interior side. This nub interior undercut 8 is formed by the shaping 8, wherein the shaping 8 in the exemplary embodiment shown is sickle-shaped and/or shaped as an arc segment and/or shaped as a crescent. The shaping 8 is furthermore formed by a protrusion 9 sticking out from the nub interior space 20. The shaping 8 in FIGS. 3 and 4 is provided in the area of the long side 6a of the nub 4. It is clear with the aid of FIG. 2 that the protrusion 9 in the exemplary embodiment shown is arranged in the area of the nub base 10, wherein it merges into the nub base 10. Moreover, FIGS. 3 and 4 show that the shaping 8 extends for around 90% of the long side 6a. In an embodiment (not shown), it is provided that the shaping 8 extends for at least 40%, preferably in further embodiments between 50 and 100% and especially between 60 and 90%, of the long side 6a.

[0102] Further, FIGS. 3 and 4 show that the end region 11 resulting from two converging long sides 6a is undercut-free and thus has neither an undercut 8 nor a protrusion 9 to form the undercut 8. In addition, in the exemplary embodiment shown, the resulting end region 11 is rounded and formed without corners, wherein the rounding is described by means of a circular arc segment. The radius characterizing the concavity of the long side 6a is multiple times larger than the radius determining the circular arc segment of the end region 11.

[0103] In addition, FIGS. 3 and 4 show that the nub 4 and/or the triaxial nub base 10 has mirror symmetry with respect to a center axis running at least substantially parallel to the lengthwise direction 5. This mirror symmetry is also clearly shown by FIG. 1. In the triaxial nub shape of the nub base 10 per FIGS. 3 and 4, three legs 12, 13 are provided spaced apart from each other and emerging from the middle region 7.

[0104] FIGS. 3 and 4 make it clear that a leg length 14 of one leg 13 running parallel to the center axis is shorter than the other two leg lengths 14 of the leg 12. Furthermore, in the exemplary embodiment shown, different angles of the leg axes are also provided. Basically, in all nub shapes shown for the nub 4, angles between two adjacent leg axes greater than 90 are provided. In the configuration of the nub 4 according to the invention in FIGS. 3 and 4, it is provided that the angle of the leg axis of the shorter leg 13 with respect to the leg axis of the adjacent leg 12 is greater than 120, being around 123 in the exemplary embodiment shown. Consequently, the angle between the leg axes of the legs 12 is less than 120, around 114.

[0105] The configuration of the nub 4 with a triaxial nub base 10 makes possible the nub arrangement of FIG. 1. In this exemplary embodiment, it is provided that the nubs 4 running transversely to the lengthwise direction 5 of the carrier plate 2 are arranged such that no continuous straight line running transversely to the lengthwise direction 5 of the carrier plate 2 and thus in the transverse direction 15 of the carrier plate 2 is formed on the carrier plate 2 and/or carrier plate plane 3. Furthermore, it is also provided that the nubs 4 running in the lengthwise direction 5 of the carrier plate 2 are arranged such that no continuous straight line running in the lengthwise direction 5 of the carrier plate 2 is formed on the carrier plate 2. However, not only are straight lines avoided in the lengthwise direction 5 and in the transverse direction 15, but also the nubs 4 running longitudinally and transversely to the lengthwise direction 5 of the carrier plate 2 are arranged such that no continuous straight line running at a slant to the lengthwise direction 5 of the carrier plate 2 is formed on the carrier plate 2. Consequently, no straight line results on the decoupling sheet 1, since respective individual line segments are interrupted by the nubs 4. The channel segment with the clear gap 19 occurring between two nubs 4 is arranged such that it extends in a meandering manner per FIG. 1 across the decoupling sheet 1. The lines possibly produced in the channel segment cannot continue in a straight line across the carrier plate 2. In each case, a leg 12, 13 of an adjacent nub 4 protrudes into the channel segment between two nubs 4.

[0106] Furthermore, it is understood that this can also be realized when using a different nub shape. Other triaxial nub shapes of the nub base 10 of the nub 4 are represented by FIG. 5 and denoted as variant embodiments 1 to 13. The arrangement of these possible nub shapes on the carrier plate 2 can be embodied such that the aforementioned continuous straight lines do not occur on the carrier plate 2. The triaxial embodiments 1 to 13 of FIG. 5 each exhibit at least three leg sides 6b, while it is understood that the long side 6a is formed by at least one leg side. It is not shown that the variant embodiments 1 to 13 may have an undercut 8 in the area of the long side and/or that the shaping 8 may extend for at least 40% of the long side 6a and/or along the leg side 6b.

[0107] FIG. 6 shows that, when using a triangular nub shape for the nub base 10 of the nub 4, an arrangement on the carrier plate 2 is provided such that no continuous straight line of the channel segment of adjacent nubs 4 results on the carrier plate 2. The center points of the nubs 4 and/or the nub bases 10 per FIG. 3 are arranged on straight lines running parallel to the lengthwise direction 5 and on lines running parallel to the transverse direction 15.

[0108] Also in the triaxial configuration of the nub base 10 in accordance with the invention in FIGS. 3 and 4, these nubs 4 are arranged on the carrier plate 2 such that an arrangement per FIG. 1 is produced, wherein the nubs 4 are arranged running in rows in the lengthwise direction 5 and in the transverse direction 15. The center points of the nubs 4 running in the lengthwise direction 5 are arranged on a line running at least substantially parallel to the lengthwise direction 5. In addition, the center points of the nubs 4 running transversely to the lengthwise direction 5 are arranged on a line running at least substantially perpendicular to the lengthwise direction 5 and thus in the transverse direction 15. This arrangement of the nubs 4 produces a symmetrical series of nubs within the respective row, wherein this arrangement in particular makes it possible for the aforementioned continuous straight lines and/or weakening lines not to occur on the carrier plate 2.

[0109] However, not only are the center points of the nubs 4 and/or the nub bases 10 arranged in rows on the decoupling sheet 1 of FIG. 1, but also the arrangement is such that the nubs 4 arranged in succession in a row running at least substantially parallel to the lengthwise direction 5 extend in such a way that the shorter leg 13 of the nubs 4 is oriented in the lengthwise direction 5. In an immediately adjacent row running at least substantially parallel to the lengthwise direction 5, the nubs 4 arranged in succession are oriented such that the shorter leg 13 of the nubs 4 is oriented opposite to the lengthwise direction 5. This results in an alternating nub orientation in a row running at least substantially parallel to the transverse direction 15.

[0110] For the arrangement of the decoupling sheet 1 on an ground 18, a connection means 17 is provided per FIG. 2. This connection means 17 is placed on the outside 16 of the nub bases 10. In the exemplary embodiment shown, the connection means 17 is secured to the outside 16 of the nub bases 10. A nonwoven was used as the connection means 17 in the exemplary embodiment shown. It is understood that in further variant embodiments (not shown), one could also use a textile and/or paper and/or a scrim and/or a lattice. The connection means 17 is provided with a lattice-like configuration in the exemplary embodiment shown. In an embodiment (not shown), besides the lattice-like formation, a formation is also possible over the entire surface.

[0111] Furthermore, the nub 4 of FIG. 2 has a height of 3 mm. In further embodiments, which are not shown graphically, a height between 1 and 4 mm, further preferably between 2.5 and 3.5 mm, is provided. Further, the clear gap 19 between adjacent nubs 4 in the exemplary embodiment shown is greater than 2 mm. The clear gap 19 between the nubs 4 varies on the decoupling sheet 1 of FIG. 1, so that a clear gap 19 between roughly 3 mm and 9 mm can be provided, preferably between 4 and 8 mm, further preferably between 5 and 6 mm. Moreover, FIG. 1 shows that the ratio between the area of the nub bases 10 of all the nubs 4 and the area of the carrier plate 2 is at least substantially around 50%. In further embodiments, the ratio can be between 40% and 70%, preferably between 45% and 55%.

[0112] Moreover, FIG. 2 shows that tiles 23 are provided on top of the carrier plate 2. Joints 24 result between adjacent tiles 23. For connecting the tiles 23 to the decoupling sheet 1, a tile adhesive is provided, which is applied both in the nub interior space 20 and on the carrier plate 2. It catches inside the undercut 8 and/or penetrates into the protrusion 9. Regardless of the orientation of the decoupling sheet 1 on an ground 18, the joints 24 between the tiles 23 do not coincide with a weakening line and/or a continuous line on the carrier plate 2. The possible continuous line produced between two nubs 4 cannot continue across adjacent nubs 4.

[0113] In further exemplary embodiments per FIGS. 7 to 13, it is provided that protrusions 21a, 21c and/or recesses 21b, 21d may be present both on the nub base 10 and on the carrier plate 2. It is understood that recesses 21b, 21d are respectively provided between adjacent protrusions 21a, 21c. In the end, basically one recess is adjacent to a protrusion 21a, 21c and/or recess 21b, 21d.

[0114] FIGS. 7 to 12 show a carrier plate 2 and nubs 4, wherein the nub interior space 20 is open toward the carrier plate 2. On the side of the nub base 10 facing toward the nub interior space 20 in FIGS. 9 to 11 the protrusions 21a and/or recesses 21b may be provided. In the exemplary embodiments shown, the protrusions 21a in FIGS. 9 to 11 are provided on all nub bases 10 shown for the decoupling sheet 1. It is to be understood, however, that in one exemplary embodiment (not shown), only at least one nub 4 has at least one protrusion 21a and/or recess 21b. A perforation of the carrier plate 2 with the protrusions 21c and/or recesses 21d is shown in the exemplary embodiment of FIGS. 7 to 8 and FIGS. 11 to 12. Here, the protrusions 21c are provided on the side facing toward the nub interior space 20. Accordingly, recesses are provided on the side of the carrier plate 2 facing away from the nub interior space 20 and/or the nub base 10, corresponding to the protrusions 21c. In the end, it is understood that on the side of the carrier plate 2 facing toward the nub interior space 20 a recess 21d may be provided next to each protrusion 21c. In the exemplary embodiments, a plurality of protrusions 21c is provided on the carrier plate 2. It is to be understood that in further exemplary embodiments that are not shown, at least one protrusion 21c can be provided on the carrier plate 2.

[0115] The protrusions 21a, 21c and/or recesses 21b, 21d may take on various geometrical shapes and structures. For example, several of the depicted embodiments shall be explained in the following. In the end, it is understood here that in the end different protrusions 21a, 21c with different structures may be provided according to the invention in other embodiments (not shown). In the end, it is decisive for the protrusions 21c and/or recesses 21b that the tile adhesive for connecting the tiles 23 to the decoupling sheet 1 can penetrate into the protrusions 21c and/or recesses 21b and fill them up almost completely. This is illustrated with the aid of FIG. 13.

[0116] In the embodiments shown, a multitude and/or plurality of protrusions 21a, 21c and/or recesses 21b, 21d are provided either on the carrier plate 2 or on the nub base 10 or on both. The protrusion 21a on the nub base 10 is formed in the shape of a spiral and/or an arc segment according to FIGS. 9 and 11. This spiral trend of the protrusion 21a emerges from the middle region 7 of the nub base 10. A multitude of protrusions 21a per FIG. 10 may be provided not only on the nub base 10 itself, but also on the leg bottom 22 of a leg 12, 13.

[0117] Not shown is that in a further embodiment the protrusions 21a, 21c and/or the recesses 21b, 21d are arranged in an irregular manner and/or unordered manner on the carrier plate 2 and/or the nub base 10, wherein in particular they have different shapes and/or structures. In the end, the protrusions 21a, 21c and/or recesses 21b, 21d act to produce a structured surface of the nub base 10 and/or the carrier plate 2.

[0118] Per FIG. 8, the protrusions 21c of the carrier plate 2 have a shaping designed to create an undercut. In a further embodiment (not shown), it is provided that the protrusions 21a and/or the recesses 21b of the nub base 10 also have a shaping to create an undercut.

[0119] Moreover, in another embodiment (not shown), it is provided that the protrusions 21a, 21c and/or the recesses 21b, 21d have a height and/or a depth greater than 1 m, preferably greater than 100 m, further preferably between 100 and 1000 m and especially between 300 and 500 m.

[0120] In the end, it is understood that the protrusions 21a and/or recesses 21b of the nub base 10 may also merge directly into the protrusions 21c and/or recesses 21d of the carrier plate 2, wherein in particular the structure and/or shape of the protrusions 21a, 21c and/or the recesses 21b, 21d can be interrupted when the carrier plate 2 has a recess on account of the nub 4 and/or when the carrier plate 2 merges into the nub 4. It is also understood that the protrusions 21a and/or the recesses 21b on the nub base 10 interrupt its geometrical structure, especially when the nub wall of the nub 4 merges into the protrusion 21a and/or the recess 21b of the nub base 10.

[0121] FIG. 9 shows that protrusions 21a in the shape of an arc section are provided on the leg bottom 22 concentrically to the middle region 7 around the center point of the nub 4.

[0122] FIG. 10 shows a further geometrical shape of the protrusions 21a, wherein the protrusions 21a are formed on the nub base 10 web-like and/or at least substantially rectangular-shaped and/or elliptical-shaped. The protrusions 21a on the nub base 10, being web-like and/or at least substantially rectangular-shaped and/or elliptical-shaped are provided per FIG. 10 transversely and/or longitudinally to the lengthwise direction 5 of the carrier plate 2.

[0123] In addition, FIG. 7 shows that a plurality of protrusions 21c and/or recesses 21d is present on the carrier plate 2 in the exemplary embodiment shown, wherein the protrusions 21c are arranged in rows running transversely to the lengthwise direction 5 of the carrier plate 2. FIG. 7 represents web-like and/or rectangular-shaped protrusions 21c on the carrier plate 2. The elongated protrusions 21c shown in FIG. 7 extend with their lengthwise dimension solely transversely and/or longitudinally to the lengthwise direction 5 of the carrier plate 2. The protrusions 21c in the exemplary embodiment of FIG. 7 are arranged in a row with alternating orientation, running longitudinally and/or transversely to the lengthwise direction 5 of the carrier plate 2.

[0124] FIG. 8 shows that the protrusions 21c are formed rectangular-shaped. In an embodiment (not shown), the protrusions 21c of the carrier plate 2 are formed elliptical-shaped. In the end, it is understood that recesses 21d may also have the geometrical shapes of the protrusions 21c.

[0125] FIG. 13 shows a cross sectional view along section II-II of FIG. 11, wherein it illustrates that the recesses 21b are arranged on the nub base 10 on a connection means 17, wherein the tile adhesive for connecting the tiles 23 to the decoupling sheet 1 and/or the carrier plate 2 penetrates into the protrusions 21c of the carrier plate 2 and/or into the recesses 21b of the nub 4.
