Description

[0001] The invention relates to a stone composite according to the preamble of claim 1 and to a laying unit for such a stone composite according to the preamble of claim 2.

[0002] German utility model DE 20 2014 103 839 U1 discloses a set of roughly cuboid-shaped paving stones, which can be used to lay a stone composite. The paving stones in this set can be combined to form a laying unit and laid in this form. However, a disadvantage of this set of roughly cuboid-shaped paving stones has been found to be that the stones in a laying unit are not stable when this laying unit, or rather the stones positioned within it, are gripped from the outside. This leads to the individual stones slipping against each other, so that the laying unit can either no longer be gripped at all, or in particular, can no longer be laid with a precise fit.Thus, in practice, the set of approximately cuboid-shaped paving stones according to DE 20 2014 103 839 U1 can only be laid individually and by hand, which makes laying not only expensive and time-consuming, but also labor-intensive.

[0003] The invention is based on the object of providing a stone composite and a paving stone laying unit suitable for producing such a stone composite while avoiding the aforementioned problems, wherein the paving stone laying unit enables a variety of combinations of paving stones within a laying unit and, moreover, it is possible to lay the laying unit as a whole in a positionally accurate and stable manner.

[0004] This object is achieved by a stone composite according to claim 1 and by a paving stone laying unit according to claim 2.

[0005] In particular, the object is achieved by a stone composite made from a set of at least three different types of approximately cuboid paving stones, such as small stones, binding stones and normal stones, each having the following features: irregularly contoured outlines in plan view; a ratio of a top view area (F1) delimited by the outline to an area (F2) of a smallest rectangle enclosing the outline is F1 : F2 = 0.90 - 0.98, in particular approximately 0.94 - 0.96; a ratio of a width (B) to a length (L) of the smallest rectangle enclosing the outline is B : L = 0.50 - 0.91, wherein the stone composite is formed from at least one approximately rectangular, in particular clampable, laying unit, wherein at least one outer corner region of the laying unit is defined by at least one longitudinally and at least one transversely oriented paving stone, wherein the longitudinally oriented paving stone lies essentially parallel to one longitudinal side and the transversely oriented paving stone lies essentially parallel to the adjoining transverse side of the laying unit.

[0006] An essential point of the invention is that the paving stones according to the invention, although they have irregularly contoured outlines when viewed from above, are designed in such a way with regard to their better overall shape that the outline of the paving stones can be conceptually circumscribed by a rectangle, on the four sides of which there are at least one, but possibly also several, contact areas of the respective paving stones with the rectangle and a respective paving stone, or rather its outline viewed from above, fills at least 90% of the rectangular area.

[0007] Another important point of the invention is that the width to length ratio of the individual paving stones according to the invention varies from 0.5 to 0.91, so that the stones according to the invention can be perfectly and precisely joined together to form a rectangular laying unit, so that the laying unit can be clamped without the paving stones slipping against each other within the laying unit and / or losing their position.

[0008] This is also possible according to the invention in particular in that at least one outer corner region of the laying unit is defined by at least one longitudinally and at least one transversely aligned paving stone, which lie against both a longitudinal side and the adjoining transverse side of the laying unit.

[0009] According to the invention, it has been found that the fact that at least one outer corner region of the laying unit is defined by at least one longitudinally and at least one transversely aligned paving stone allows stabilization of the laying unit to be achieved in an extremely simple and surprisingly effective manner, namely in particular when the essentially rectangular laying unit is clamped, for example with a lateral retaining strap or with other clamps that substantially completely surround the laying unit laterally.This stabilizing effect by a lateral arrangement of longitudinally aligned paving stones along a longitudinal and a transverse side of the laying unit can be further improved according to a preferred embodiment of the invention in that paving stones aligned longitudinally and / or transversely along the respectively associated longitudinal and / or transverse side of the laying unit extend from the at least one corner region at least to a quarter, preferably to a third and particularly preferably to at least a half along the respective associated longitudinal and transverse side of the laying unit.

[0010] As mentioned above, the object of the invention is further achieved by a rectangular paving stone laying unit consisting of several sub-formations, in particular rectangular, trapezoidal, triangular, pentagonal or similar polygonal or approximately circular sub-formations, each composed of several types of approximately cuboidal paving stones that differ in shape and size and approximate a respective rectangle, each with an irregularly contoured outline when viewed from above, wherein these different stone types within each sub-formation are aligned longitudinally and transversely and optionally in opposite directions to one another, and wherein at least one outer corner region of the laying unit is defined by at least one longitudinally aligned paving stone that lies against both a long side and the adjoining transverse side of the laying unit, or at least one side of the rectangle, in particular at least by a quarter,preferably one-third and particularly preferably at least one-half of each longitudinally aligned paving stones is limited, namely in particular forming a clampable laying unit, wherein the laying unit is formed in particular by the arrangement of the subformations.

[0011] By providing subformations, which are particularly rectangular, but according to the invention can also be trapezoidal, triangular, pentagonal, or polygonal, or even approximately circular, the laying variability of the paving stones used according to the invention can be increased in an aesthetically pleasing manner to form a stone composite. These subformations can be integrated into a respective laying unit according to the invention while observing the above-mentioned boundary conditions. Such a laying unit composed of subformations, which is stabilized either over at least one corner and / or along at least part of a longitudinal and / or transverse side with longitudinally aligned paving stones, can be clamped, as already mentioned, by means of a retaining strap or with the aid of clamps, so that such a laying unit can be laid as a whole to form a stone composite.

[0012] Thus, the object according to the invention is also achieved by a stabilizing unit for a laying unit, in particular according to the above statements, wherein the stabilizing unit defines an outer corner region of a laying unit, which is formed by at least one longitudinally and at least one transversely oriented paving stone, wherein the longitudinally oriented paving stone lies essentially parallel to one longitudinal side and the transversely oriented paving stone lies essentially parallel to the adjoining transverse side of the laying unit.

[0013] It has proven particularly expedient if the stabilizing unit comprises paving stones, or is composed of such paving stones, which, starting from a respective corner region, extend longitudinally and / or transversely along the longitudinal and / or transverse side of the laying unit assigned to the respective corner region and in this way are arranged from the at least one corner region at least one quarter, preferably one third and particularly preferably at least one half along the respective assigned longitudinal and transverse side of the laying unit.

[0014] In this case, the subformations in the assembly of a laying unit are aligned and dimensioned relative to each other in such a way that the laying unit formed from them can be clamped as an approximately rectangular unit.

[0015] According to the invention, a respective subformation has a surface area in plan view that is defined to approximately 90-98%, in particular to approximately 94-97%, by the respective top view surfaces (F1) of the paving stones forming the subformation. In this way, the respective paving stones used to form the subformation fill a respective subformation formed from the paving stones in such a way that the paving stones are arranged securely within the subformation, but still leave enough space between the paving stones that the design formed from the individual paving stones and the irregular outlines of the individual paving stones in plan view are clearly visible.

[0016] According to one embodiment of the invention, a respective subformation which is substantially rectangular, trapezoidal, triangular or polygonal or round or oval in plan view is surrounded by a theoretically elastic band, so that a mutual pushing together of adjacent subformations via their respective substantially rectangular, trapezoidal, triangular or polygonal or round or oval outer boundaries is possible and this may result in overlapping areas of the subformations.

[0017] According to this embodiment of the invention, it is advantageously possible for a respective subformation to have an outer boundary which essentially surrounds the arranged paving stones, or essentially defines the outer shape of the subformation, but for individual paving stones to protrude beyond the outer boundary of the subformation predetermined by the imaginary elastic band, or for not all paving stones to actually reach the imaginary outer boundary of the subformation.A mutual support of the paving stones in pushed-together subformations then results from the fact that paving stones that protrude slightly beyond an outer boundary of a subformation theoretically protrude into the subformation adjacent to the subformation, so that the individual paving stones come into contact with each other and support each other, so that slipping within the resulting formation of the paving stones is practically no longer possible, especially not if the formation as a whole, or the laying unit formed from it, is clamped.

[0018] It should be noted here that the imaginary elastic band representing the outer boundary of a subformation, for example, in the case of a rectangular subformation, actually has a rectangular shape without dents or bumps. The same applies to differently shaped subformations, which, when viewed from above, are trapezoidal, triangular, or polygonal, but also round or oval. In any case, the imaginary elastic band describes an ideal shape of such a shape without dents or bumps.

[0019] Thus, for example, a rectangular subformation in the clampable state of a laying unit is delimited by approximately straight lines, in particular by a smallest rectangle delimiting all stones of a subformation, wherein at least some of the lines delimiting the subformation at least partially overlap at the mutually facing corners and / or optionally in the region of lateral boundary lines of one or more adjacent subformation(s) in an overlapping area, so that the paving stones of such adjacent subformations support each other in a mutually touching manner.

[0020] The object according to the invention is also achieved by a laying unit, in particular according to the above statements, wherein a row of longitudinally aligned paving stones extends both over at least one long side and over at least one transverse side of the laying unit adjoining the long side, in particular forming a stabilizing unit, and thereby in particular defines respective outer sides of the laying unit.

[0021] In a particularly preferred manner, such a laying unit, in which the paving stones extend over at least one longitudinal side as well as over at least one transverse side of the laying unit adjoining the longitudinal side, represents a particularly well-stabilized laying unit, since an optimized stabilization structure is provided due to the paving stones being aligned longitudinally both with regard to the longitudinal side and with regard to the transverse side when the laying unit is clamped.

[0022] Furthermore, a laying unit in which at least one, preferably several, rectangular and / or triangular and / or trapezoidal and / or circular and / or polygonal subformation(s) is / are arranged within the respective outer sides and / or corner regions and in which these subformation(s) fill approximately 95 - 97% of an area within an outer boundary defined by the longitudinally aligned paving stones, represents a particularly preferred embodiment of the invention, since mutual support of the paving stones against one another within such a laying unit is very well ensured, without full-surface contact between the paving stones being necessary to prevent individual stones from slipping against one another within the laying unit, as is the case in the prior art.

[0023] According to the invention, a laying unit is formed from a plurality of, preferably different, subformations, in particular from 2 to 30, preferably from 4 to 20 and particularly preferably from 8 to 18 subformations.

[0024] The individual subformations from which the laying unit is composed are either essentially the same size in terms of area or have different shapes and / or sizes, so that subformations placed next to one another can practically fill the area of ​​a laying unit with a wide range of variation so completely that, when viewed from above, on the one hand, the impression is created of either regularly or, in some cases, very irregularly laid "natural stones" with an "organic" overall impression, and on the other hand, the laying unit is so well filled that all paving stones support each other and against each other in such a way that the laying unit, especially when clamped, can be easily laid together with other similar laying units to form a stone composite.

[0025] In this regard, it has proven particularly advantageous according to the invention if a respective subformation is formed from at least two, but preferably from 3 to 8, paving stones, in particular from at least 2 to 7 paving stones.

[0026] Furthermore, it has also proven particularly advantageous according to the invention if at least 50%, preferably 75% of the paving stones forming a respective subformation adjoin one another in pairs via their respective long sides, in particular congruently, and / or the paving stones forming a respective subformation adjoin one another in pairs exclusively via their respective narrow sides, in particular congruently, since in this way slip resistance of the paving stones within a laying unit and thus at a later stage also within the stone composite can be ensured.

[0027] A particularly important and particularly advantageous aspect of the present invention is that the paving stones used in the invention have irregularly contoured outlines when viewed from above. These irregularly contoured outlines are reminiscent of a view such as that of potatoes grown naturally and organically.

[0028] These contours, which are irregularly contoured in plan view, can thus be referred to as a potato-shaped outer contour of a paving stone used according to the invention, wherein this outer contour is characterized in that the stones according to the invention do not have a predetermined, regularly designed outer contour, but can be shaped almost arbitrarily. The potato-shaped outer contour of the paving stones used according to the invention can therefore have convex as well as concave sections with different merging curve radii, so that the paving stones used according to the invention give a quasi organically grown impression in plan view. An essential point of the invention is that this outer contour, which is potato-shaped in plan view, of a paving stone used according to the invention, in particular does not consist of basically regular, i.e.This can result in regularly triangular, regularly square, regularly pentagonal, regularly hexagonal, etc., or regularly round or regularly oval stones, which merely exhibit projections or recesses leading to a certain irregularity. Rather, a paving stone used according to the invention appears, when viewed from above, as a "natural unit" that, for example, does not have any clearly or sharply defined edges or corners along its outer contour, but only curves.

[0029] The term "top view" refers here according to the invention to a properly laid state of the paving stones used according to the invention, in which the paving stones can be viewed from above and their side surfaces border or can border on neighboring paving stones.

[0030] Another very important point of the invention is that the cuboid paving stones have a potato-shaped outer contour in plan view, which is essentially flat and smooth on its visible side, so that a flat paving stone arrangement can be formed from the paving stones used according to the invention.

[0031] The side surfaces of the paving stones according to the invention extend at an angle of substantially 90° ± 5° to 30°, preferably ± 5° to 25° and particularly preferably ± 5° to 20° in the direction of the side opposite the visible side having the potato-shaped outer contour.

[0032] In this regard, it should be noted that the paving stones according to the invention do not have a base and can thus be laid on both sides, ie with their underside on top or with their top side on top.

[0033] As mentioned above, the side surfaces of the paving stones according to the invention can thus extend at an angle of 90° from an upper side of the stones to their respective underside, so that the paving stones according to the invention run essentially in a mirror image along a cutting line which is horizontal in the laid state and can accordingly also be laid in a mirror image.

[0034] As also mentioned above, the paving stones according to the invention can have a certain conicity from their top side to their bottom side, so that this conicity can, for example, create a certain optical distance between the stones when viewed from above on a pavement laid with such stones, whereby stones with different or no conicity can be combined. Furthermore, for example, stones with identical but opposing conicity can also be combined with one another in such a way that the respective side surfaces of these stones virtually wedge against one another and offer a pavement resulting from stones laid in this way additional stability, particularly with regard to the risk of slipping against one another.

[0035] As has been shown by the invention, such cuboid paving stones with an irregularly contoured outline in plan view and possibly conical side surfaces can be used to create a wide variety of aesthetically very appealing stone combinations, which can either give an organically grown impression that resembles a certain natural symmetry, such as the waves of a lake, or a completely disordered impression, such as a buried accumulation of stones.

[0036] Furthermore, the object according to the invention is also achieved by a pattern arrangement for a laying unit according to the above statements, wherein the paving stones in the laying unit are arranged such that a contact line between two paving stones which together form a paving stone pair is defined by two paving stones adjoining one another along their respective long sides or along their respective narrow sides, wherein the contact line, viewed in one of the two directions of the contact line, in particular in the long and / or the transverse direction, abuts a long side or a narrow side of a stone arranged in alignment with the contact line at the latest after three, preferably two and particularly preferably one essentially co-oriented paving stone pair(s).

[0037] The fact that a contact line, which is notionally arranged between two paving stones which adjoin one another with their long sides or with their transverse sides, in its extension at the latest after three further such contact lines which lie in the extension of the first contact line, abuts against a long side or a narrow side of a paving stone arranged in this alignment of the contact line, means that the paving stones of the laying unit according to the invention cannot slip along an alignment, but are always stopped by a paving stone lying transversely or lengthwise to a respective contact line, i.e. are prevented from slipping, as can happen in the prior art.

[0038] Furthermore, the fact that at the latest after their first, second or at the very latest third contact line, which are in line, another paving stone is placed exactly in this line, either crosswise or lengthwise, advantageously leads to the fact that a laying unit on a small scale or a stone combination on a large scale always makes a very aesthetic and, as desired, "messy" "organic" impression, reminiscent of nature, such as in a stream bed.

[0039] Thus, such a longitudinal and transverse laying of paving stones according to the invention fulfills a dual function, which is on the one hand that the paving stones prevent each other from slipping against each other and on the other hand that they leave a visually very appealing overall impression of a "natural" stone composite.

[0040] This overall impression and also the dual function of the paving stones used in the laying unit according to the invention and in particular their laying arrangement defined in the laying unit according to the invention can be further supported according to a further embodiment of the invention in that individual paving stones of the laying unit are replaced by two smaller paving stones which have a substantially half-sized top surface (F1).

[0041] These half smaller paving stones with an essentially half visible surface make up a proportion of a maximum of 30%, preferably not more than 20% and particularly preferably not more than 10% of a total visible surface of all paving stones of the laying unit, in particular a maximum of 6%, preferably not more than 4% and particularly preferably not more than 2% of a total visible surface, in the assembly of a laying unit and thus later also in a stone assembly.

[0042] Further embodiments of the invention emerge from the subclaims.

[0043] The invention is described below using exemplary embodiments, which are explained in more detail with reference to the figures. Herein: Fig. 1 shows a schematic representation of a laying unit according to the invention in accordance with a first embodiment of the invention; Fig. 2 shows a schematic representation of a laying unit according to the invention in accordance with a second embodiment of the invention; Fig. 3 shows a schematic representation of embodiments of subformations according to the invention; Fig. 4 shows a schematic representation of four subformations in an overlapping arrangement according to an embodiment of the invention; Fig. 5 shows the laying unit according to Fig. 2 in perspective view; Fig. 6 a schematic representation of a laying unit according to the invention according to a further embodiment of the invention; Fig. 7 a schematic representation of a laying unit according to the invention according to a further embodiment of the invention; Fig. 8 a schematic representation of a paving stone according to the invention with a circumscribed rectangle; Fig. 9 a schematic representation of two small stones according to the invention with a circumscribed rectangle; Fig. 10 a schematic representation of a subformation according to the invention according to Fig. 3 ; and Figs. 11 and 12 each show a schematic representation of an arrangement of possible subformations for a laying unit according to the invention.

[0044] In the following description, the same reference numbers are used for identical and equivalent parts.

[0045] Fig. 1 shows a schematic representation of a laying unit 20 according to the invention according to a first embodiment of the invention, wherein paving stones 10 are combined to form a laying unit 20 with a long side 40 and a transverse side 50. As in Fig. 1 As can be seen, a corner region 30 in the form of a stabilizing unit 90 is formed in the lower right corner of the laying unit 20, wherein the stabilizing unit 90 is formed in that an outermost row of longitudinally laid paving stones 10 is arranged along a long side 40 of the laying unit 20 and a paving stone 10 is arranged in the longitudinal direction of the long side 50 along a long side 50 of the laying unit 20, so that the paving stones 10 laid along the long side 40 and along the long side 50 in the respective longitudinal direction form on the one hand an edge boundary and also a corner boundary of the laying unit 20 according to the invention.

[0046] Furthermore, in Fig. 1 It can be seen that respective paving stone pairs 80 of the laying unit 20 define a contact line 70 between one another, wherein the contact line 70, in its respective alignment direction, ends at a narrow side or a long side of another paving stone 10 lying in the alignment direction. In this way, it is not possible for one of the paving stones 10 of the paving stone pair 80 adjacent to the contact line 70 to slip in the direction of the paving stone 10 lying in the alignment direction of the contact line 70. In this way, the laying unit 20 according to the invention is stabilized such that all paving stones 10 of the laying unit 20, in particular when the laying unit 20 is clamped, cannot slip against one another.

The subformations 60 are arranged, for example, in a laying unit 20, wherein the laying unit 20 also has a longitudinal side 40 and a transverse side 50.

The Fig. 6 and Fig. 7 each show schematic representations of further laying units 20 according to the invention according to further embodiments of the invention, wherein Fig. 6 has randomly arranged paving stones 10 and wherein the laying unit 20 according to Fig. 6 has three corner areas 30, in which paving stones 10 are arranged along the respective long side 40 and the respective transverse side 50 in the longitudinal direction, so that the paving stones 10 arranged in the laying unit 20 are secured against slipping by means of stabilizing units 90, in particular when the laying unit 20 is clamped. Furthermore, Fig. 6 Contact lines 70 are shown in the form of thickened lines, each arranged between two paving stones 10, each forming a paving stone pair 80. In each alignment of the contact line 70, a paving stone 10 is arranged such that the contact line 70 meets the narrow side or the long side of the paving stone 10.

Fig. 7 shown how subformations 60 are arranged by way of example in the laying unit 20, so that the laying unit 20 is completely filled with paving stones 10, which can no longer slip against each other when clamped.

[0052] Fig. 8 shows a schematic representation of a paving stone 10 according to the invention with a circumscribed rectangle, wherein it can be clearly seen that the top surface F1 of the paving stone 10 forms only a fraction of approximately 92% of the rectangular surface F2 of the rectangle circumscribing the paving stone 10.

[0053] Fig. 9 shows a schematic representation of two paving stones 10 according to the invention in the form of smaller paving stones, i.e., small stones 10' with a circumscribed rectangle. The respective smaller paving stones 10' each have, in plan view, essentially half the surface area of ​​a normal paving stone 10.
