DESCRIPTION OF THE EMBODIMENTS

[0042] Initially with reference to the illustration on FIG. 1, a decoupling element 1 is shown and described, which according to the first embodiment depicted on FIGS. 1-9 can consist solely of a plastic layer 2. As will be described in even more detail further below, a fleece layer 20 and/or 21 can alternatively be provided on one or both sides of the plastic layer 2 (see FIGS. 10 and 11).

[0043] The plastic layer 2 can be fabricated through deep drawing, for example, and has a longitudinal extension 1 as well as a width extension b viewed transversely thereto.

[0044] The plastic layer 2 has rib-like formations 3 that were elongated in the longitudinal extension 1, for example as the result of deep drawing. According to the sectional view on FIG. 3, these can be at least approximately semicircular in design in a cross section transverse to the longitudinal extension 1, with a surface 4 that faces a first broadside B.sub.1 of the plastic layer 2.

[0045] As also illustrated, the plastic layer 2 can have an essentially constant material thickness a over the entire longitudinal extension 1 and the entire width extension b. This material thickness a can measure roughly 0.2 mm or more, for example, and further 0.5 mm up to 1 mm or 2 mm, for example.

[0046] A respective groove-like recess 5 with an interior surface 6 that possibly runs concentrically to the surface 4 in the cross section according to FIG. 3 arises on the second broadside B.sub.2 lying opposite the first broadside B.sub.1 in the area of the formations 3.

[0047] The formations 3 are arranged one after the other in a chain-like manner as viewed in the direction of longitudinal extension 1. The individual formation rows preferably run parallel to each other, wherein a groove 7 that is continuous relative to all formations 3 generated one after the other in their longitudinal extension remains between two rows of formations 3 running one right next to the other, and hence on both sides of the formations 3, transverse to their longitudinal extension. This groove 7 preferably extends along a straight line, doing so with a depth t that stays constant over the length in the longitudinal extension 1, wherein this depth t is dissipated perpendicular to a plane U that contacts the formations 3 in the area of their respective zenith on the surface 4.

[0048] With respect to all formations 3 generated one after the other in their longitudinal extension, each groove 7 simultaneously forms a wall 8 on both sides that appears continuous on the second broadside B.sub.2, wherein the wall 8 transitions into the wall comprising the formations 3 on the first broadside B.sub.1 in a longitudinal extension 1 with interruptions.

[0049] Each formation 3 is bordered in its longitudinal extension 1 by sections 9 of reduced height and, in the exemplary embodiment shown, of reduced width as well. As viewed in the width extension b, the section 9 can here have a width extension dimension c′ that can correspond to roughly one fourth to one half, further for example to one third, of the largest width extension dimension c of a formation 3 as viewed in the same direction.

[0050] The height h of each formation 3 perpendicular to the plane U can further correspond to 1.5 to 4 times, for example, further roughly to 2 to 3 times, for example, of the reduced height h′ of the section 9 that connects the formations 3 in a longitudinal direction (see FIG. 3).

[0051] With respect to the recesses 5, correspondingly in relation to the second broadside B.sub.2, these connecting sections simultaneously form bordered partial areas 10 of less depth s′ and possibly also less widths d′ viewed transverse to the longitudinal extension 1, wherein this depth s′ can correspond to roughly one fifth to one half, further for example to one fourth or one third, of the depth s of a recess 5. The respective depth s, s′ is dissipated perpendicular to a plane O, which runs parallel to the plane U in the area of the second broadside B.sub.2 and contacts the plastic layer 2 in areas arising in the transition of the walls 8 into the partial areas 10 or in the transition to the wall of an adjacent recess 5. The reduced width d′ can correspond to roughly 0.2 to 0.7 times, for example to 0.5 times, the largest width d of a recess as viewed transverse to the longitudinal extension 1.

[0052] As also shown, the formations 3 that are separated from each other by the sections 9 in the longitudinal extension 1, but by all means connected with each other in a chain-like manner by the sections 9, can have identical formation lengths, and further preferably identical widths c as viewed transversely thereto as well.

[0053] The rows of formations 3 can also be arranged offset relative to each other as viewed in the longitudinal extension in such a way that yields a “gap” arrangement in relation to the sections 9.

[0054] A section 9 can further be arranged between two formations 3 arranged one behind the other, roughly centrally relative to the longitudinal extension of a formation 3 of an adjacent formation row.

[0055] Accordingly, this type of offset arrangement can also be provided relative to the partial areas 10 that connect the recesses 5 in series.

[0056] The trough-like recesses 5 of a row are further connected with each other in an overflow manner by the partial areas 10 below the plane O. As a result of the wall 8 that runs in a longitudinal extension 1—due to the continuous groove 7 on the opposing broadside—the recesses 5 of one row are separated from the recesses 5 of the directly adjacent row.

[0057] The arrangement and dimensional shaping or spacing of the formations 3 can further be selected in such a way that a plane E running parallel to the planes U or O can be set up according to the schematic illustration on FIG. 6, which extends below the largest height of the recesses 5 in the plane U and above the sections 9 of reduced height h′ (see also FIG. 3).

[0058] As evident from FIG. 6, this type of an arrangement of a geometric plane E yields an island-like emersion of formations 3 above the plane E over roughly half their height extension h.

[0059] The remaining surface F between the formations 3 that is projected perpendicular to the plane E can correspondingly have a grid-like structure, with free surfaces 11 that run between two adjacently running formations 3, and hence cover the groove 7 in the longitudinal extension, and are connected with each other in the area of sections 9 of reduced height h′ by connecting surfaces 12 running transversely thereto. These connecting surfaces 12 arise from partial surfaces 13, which each arise allocated to a groove 7.

[0060] With respect to an additional geometric plane E′ that is aligned parallel to the plane E described above and aligned in such a way as to pass through both the recesses 5 and the partial areas 10 of less depth s′, a continuous, planar geometric cover surface D can arise in a perpendicular projection between two walls 8 lying one directly opposite the other (see FIG. 7), which is separated from an adjacent cover surface by the wall 9.

[0061] Corresponding to the plane E′, this cover surface D runs below a largest height of the wall 8.

[0062] The cover surfaces D of a row of recesses 5 arranged one after the other in a longitudinal extension are connected with each other in a chain-like manner in the partial areas 10 of less depth s′ via connecting sections 14, wherein a connecting section 14 consists of partial sections 15 allocated to the respective recess 5.

[0063] As evident from the assembly situation shown on FIG. 8, the first broadside B.sub.1 comprises the underside of the decoupling mat 1. Accordingly, the surface 4 of the formations 3 faces downward in the direction of a support surface 16 of the floor 17. A roughly linear support for the decoupling mat 1 over the zenith areas of the formations 3 on the support surface 16 can here arise. In any event, the configuration described above only yields a small interrupted support in the area of the formations 3. The grooves 7 are also connected with each other in the use position according to FIG. 8 by the sections 9 of less height h′.

[0064] An adhesive mortar 18 can be directly applied to the upper side of the plastic layer 2 formed by the second broadside B.sub.2, for purposes of adhesively fixing ceramic and stoneware tiles 19, for example.

[0065] The adhesive mortar 18 here reaches into the depressions in the area of the recesses 5, as well as into the depth s′ reduced by the partial areas 10, thereby yielding a good bond.

[0066] In particular to increase the adhesive or bonding strength, a fleece layer 20, 21 can be provided on one or both sides, i.e., correspondingly on the top and/or bottom side of the plastic layer 2.

[0067] As also preferred, the fleece layer 20 allocated to the second broadside B.sub.2—corresponding to the upper side—can be provided adjusted to the contour of the surface of the plastic layer 2, and correspondingly also line the recesses 5, and further preferably also the partial areas 10 of reduced depth s′.

[0068] The upper fleece layer 20 can have a thickness corresponding to the material thickness a of the plastic layer 2, or a thickness reduced by comparison to this thickness, as shown on FIGS. 10 and 11.

[0069] As preferred, a possibly provided lower fleece layer 21 can be stretched out and extend into a plane (preferably plane U), and correspondingly preferably lies only tangentially against the surface 4 in the area of the formations 3, and is there further preferably also bonded to the plastic layer 2.

[0070] The lower fleece layer 21 can be used to adhesively fix the decoupling mat 2 configured in this way to the floor 17, wherein the hollow structure under the plastic layer 2 resulting from the formation of the grooves 7 and partial areas 10 is retained owing to the arrangement of the lower fleece layer 21 described above.

[0071] The material thickness selected for the lower fleece layer 21 can be identical to that of the upper fleece layer 20. FIG. 10 shows a lower fleece layer 21, the thickness of which can correspond roughly to the material thickness a of the plastic layer 2.

[0072] The lower fleece layer 21 can also serve as a decoupling fleece, and according to the illustration on FIG. 11 can further have a significantly larger thickness than the upper fleece layer 20, and further possibly also than the plastic layer 2, e.g., double or triple the thickness of the plastic layer 2.

[0073] The above statements serve to explain the inventions encompassed by the application as a whole, which further develop the prior art at least by the following feature combinations, each even independently, wherein two, several or all of these feature combinations can also be combined, specifically:
