Description

State of the art

[0001] The invention relates to a laying stone and a laying stone arrangement with such laying stones.

[0002] Paving stones are known in a wide variety of designs. These paving stones can have several contour elements which, when the paving stone is laid as intended, are arranged on a visible surface. The contour elements can create the impression that several smaller stones are laid in this area instead of a single paving stone.

[0003] For example, DE1930054U describes a rectangular lawn slab consisting of longitudinal ribs with a surface interrupted by transverse grooves and transverse ribs connecting the longitudinal ribs. The transverse ribs are lower than the longitudinal ribs. The longitudinal ribs form squares on their upper surface separated by grooves.

[0004] Corresponding building kits and laying stone arrangements using such laying stones are also known. Disclosure of the invention

[0005] One object of the invention is to provide a paving stone that can be laid easily.

[0006] Another task is to provide a paving stone pattern with such paving stones, with which various surface designs can be realized.

[0007] The problems are solved by the features of the independent claims. Favorable embodiments and advantages of the invention become apparent from the further claims, the description, and the drawings.

[0008] A paving stone is proposed which has a base whose outline comprises four sinusoidal sides. Furthermore, the paving stone according to the invention has several contour elements arranged within the base. The outline of the base forms an envelope for the contour elements.

[0009] A paving stone is understood to be a component or element comprising a top and a bottom surface. The bottom surface is connected to the substrate, and the top surface forms a visible surface when the paving stone is laid. The top and bottom surfaces can be positioned opposite each other. Alternatively, they can be adjacent to each other, for example, at a corner. The contour elements can be located at least on the visible surface and / or can protrude from a visible surface and / or can at least partially form a visible surface.

[0010] The outline can be formed by imaginary lines or can be defined by the edges of elements of the paving stone according to the invention. Furthermore, a combination of existing edges and imaginary lines can be used to form the outline. Similarly, the base can be an imaginary surface or a surface formed by elements of the paving stone according to the invention. Here, edges of elements can each form a section of the outline. This at least one section can connect to at least one imaginary line, which can also form a section of the outline. Several sections of the outline formed by edges can be connected to each other by imaginary lines.

[0011] For example, contour elements can be arranged close together to form an edge that defines the outline or a section of the outline. In this case, sides of the contour elements can have sections that form a section of the outline. These sections can form a continuous edge when contour elements are arranged seamlessly next to each other. Furthermore, the contour elements can overlap.

[0012] Alternatively, multiple contour elements can have sides, each forming a section of the outline, with gaps between these sections being filled by imaginary lines.

[0013] Additionally or alternatively, a base element of the paving stone according to the invention can comprise an edge forming the outline or a section thereof. Furthermore, the base element can comprise a surface that forms a portion of the base or the entire base.

[0014] Additionally or alternatively, a spacer can be arranged on the base element and / or on at least one of the edge contour elements, which has an edge that can form a section of the outline. Furthermore, it is conceivable that the outline is formed solely from imaginary lines, whereby the contour elements arranged within the base area do not intersect these imaginary lines.

[0015] The base can also be an imaginary surface. Alternatively, for example, a cross-section and / or a top surface of the base element can form the base. Alternatively, a cross-section of several interconnected contour elements can form the base, or a region or regions of the base. Additionally, a combination of imaginary regions and cross-sections or top surfaces of base elements and / or contour elements can be conceived as the base.

[0016] In the following, a contour element is understood to be, for example, an element that has at least one top surface and / or a contour and / or a shape resembling a natural stone. For instance, the contour element can be organically shaped and can, in particular, have the form of a boulder.

[0017] In the following, a contour element can also be understood as an element that has at least one top surface and / or a contour and / or a shape resembling a paving stone. The cross-section of the contour element can be a geometric shape, such as a polygon or a general polygon, a rectangle, a square, a triangle, a circle, an ellipse, or a combination of several shapes, or an organic shape.

[0018] Furthermore, many hybrid forms for the contour elements are conceivable.

[0019] The contour elements have a smaller top surface than the base surface of the paving stone.

[0020] In this context, multiple contour elements arranged within the base area can have different shapes and / or dimensions. Identical contour elements can also be arranged within the base area. Furthermore, a mixture of identical and different contour elements is conceivable. For example, a mixture of contour elements with organic shapes and contour elements with geometric shapes is possible.

[0021] Similarly, contour elements with identical shapes are conceivable, but differing in dimensions and / or orientations. Furthermore, at least two contour elements can be arranged overlapping each other, with the contour elements, in particular their upper surfaces, intersecting.

[0022] The contour elements can advantageously be arranged vertically such that, when several paving stones according to the invention are laid, the impression of a natural path and / or square made of stones or a path and / or square paved with paving stones can be created. The contour elements arranged within the base area can have different depths perpendicular to the base area, thereby creating paths and / or squares with an uneven surface. This surface can be less slippery, for example, in wet, icy, or snowy conditions.

[0023] Since several contour elements are arranged within the base of the paving stone, laying a paving stone according to the invention advantageously creates the impression that many smaller stones or paving stones are laid at that location. Many interesting laying patterns can be advantageously created by selecting and arranging the contour elements.

[0024] Due to the sinusoidal shape of the four sides of the outline, paving stones with the same outline, or with sides exhibiting the same sinusoidal function, can be easily and seamlessly laid together. Furthermore, laying such paving stones advantageously avoids sharp edges and joints, allowing for a laying pattern without a visible grid, thus creating a natural appearance for the corresponding laying pattern.

[0025] Advantageously, the paving stones according to the invention can be used as ground cover. In this case, the paving stones can be designed as floor slabs or paving stones. Furthermore, the paving stones can be used as wall or ceiling coverings. In this case, the paving stones can, for example, be designed as tiles.

[0026] The number of deflections in the sinusoidal curve of the outline's sides can be chosen arbitrarily. A deflection is defined as either convex or concave. In a curve with multiple deflections, convex deflections alternate with a maximum and concave deflections with a minimum. The amplitude of the sinusoidal curve can be chosen so that it periodically exhibits values ​​between a maximum value at the maximum and a minimum value at the minimum, where the magnitude of the maximum value is equal to the magnitude of the minimum value. Constant maximum values ​​can be chosen for the maxima and constant minimum values ​​for the minima.

[0027] For example, one side of the outline can have an equal number of minima and maxima; for instance, one side can have a concave deflection with a minimum and a convex deflection with a maximum. It is also possible for a side not to have an equal number of maxima and minima; for example, one side can have only one minimum, only one maximum, two minima and one maximum, or two maxima and one minimum.

[0028] With a favorable design of the paving stone, opposite sides of the outline of the base can run parallel to each other. One side can have a convex bulge, and the opposite, parallel side can have a concave indentation at a point opposite this convex bulge. This allows stones with the same outline, or the same sinusoidal curve, to be easily laid adjacent to each other. Convex bulges or deflections on one side can intersect with concave indentations or deflections on an adjacent side.

[0029] Furthermore, if all sides of the paving stone have the same sinusoidal function for the sinusoidal path, it can be rotated at a right angle, with the convex protrusions of one side interlocking with a concave indentation of an adjacent side. This allows the sides of adjacent paving stones to interlock, even when rotated at a right angle.

[0030] The sides can each, in particular, comprise a sinusoidal curve with a complete period or a multiple of a complete period of the sine function. This ensures that each side has at least one maximum and at least one minimum. The period starts at one corner of the base and extends to the opposite corner of the base, where the period of the next side begins.

[0031] Advantageously, such a laying stone can be rotated at a right angle by 90°, 180°, 270° or 360° about a vertical axis and simply laid with a laying stone with an identical outline or with an outline with the same sine function for the sinusoidal course of at least one side, since the convex deflection of one laying stone can engage in the concave deflection of the other stone.

[0032] In a favorable embodiment of the paving stone, the sides can abut at the corners of the base, and these corners can form the vertices of a rectangle, particularly a square. This rectangle or square can form the paving stone's laying grid. Here, the convex projection extends beyond the laying grid, and the concave projection intersects it. When laid, the convex projection of one paving stone engages with the concave projection of an adjacent paving stone. This advantageously provides anti-displacement protection. The interlocking of the convex projections or bulges and the concave projections or bulges of the sides allows shear forces from multiple directions to be absorbed without the paving stone according to the invention twisting.This is also the case with imaginary outline lines, since the contour elements arranged within the base area are positioned above or below the laying grid and can absorb shear forces.

[0033] In the following, a laying grid is understood to be a two-dimensional construct with which a surface can theoretically be covered. The laying grid is designed such that the outlines of adjacent laying grids abut each other without gaps. The laying grid encompasses the area of ​​a cross-section of the paving stone or the base area of ​​the paving stone and half the laying distance to an adjacent paving stone. Since the cross-sectional area or the base area of ​​the paving stone and half the laying distance are already included in the laying grid, a floor covering, wall covering, ceiling covering, paving pattern, and / or surface pattern can be easily planned using this grid.

[0034] With a favorable design of the paving stone, inflection points of opposing deflections can meet at the corners of the base. At these inflection points, the amplitudes have a value of zero. "Opposing" means that the amplitude of one side of the outline increases towards the corner, while the amplitude of the other side decreases towards the corner.

[0035] Advantageously, such an outline is rotationally symmetrical about 90°, 180°, 270° and 360°. This allows the paving stone to be rotated at right angles about 90°, 180°, 270° and 360° around the vertical axis, and its convex deflections can engage with concave deflections of an adjacent paving stone.

[0036] With a favorable design of the paving stone, the contour elements can be arranged on the visible surface of the paving stone when it is laid as intended, forming a contour element pattern with joints between adjacent contour elements on the visible surface. The visible surface can be either the underside and / or the top side. This allows the paving stone to form the visible surface with either its underside or its top side facing outwards. Advantageously, such a paving stone can also be rotated and laid around a longitudinal axis and / or a transverse axis. For example, the top and bottom sides can be arranged opposite each other. In this case, the stone can be rotated 180° around the longitudinal axis and / or the transverse axis, creating a different visual effect.

[0037] Several embodiments of the paving stone according to the invention can have the same base area with the same outline and, for example, include different contour element patterns on the visible surface. This allows the different paving stones to be easily laid together and, through the contour elements, create a different visual impression when laid. A multitude of laying patterns can be created with corresponding paving stones. The joints or gaps between the contour elements can be filled with jointing material or other suitable filler material, forming so-called dummy joints.

[0038] Furthermore, the joints or gaps between the contour elements can be planted with vegetation. Likewise, the joints between the paving stones can be filled with suitable jointing and / or filling material.

[0039] Since the laying pattern includes both dummy joints and actual joints, it is no longer possible to discern the exact location of the joints between the paving stones. This allows for a more organic, natural, and / or wilder, less structured, and / or less constructed appearance of the paving pattern. Furthermore, by filling and / or planting vegetation in the spaces between the contour elements and the joints between the paving stones, it becomes obscure that it is a single large paving stone with multiple contour elements. The effect can be achieved as if several smaller paving stones have been laid across the surface.

[0040] In a favorable design of the paving stone, at least one fastening element can connect at least two contour elements. In one conceivable embodiment of the paving stone, the outline of the base can be a contour formed by imaginary lines. Each side of this imaginary contour can, for example, be touched by at least two contour elements. Alternatively, a segment of the outline of a contour element can form a segment of the outline of the base. Furthermore, it is conceivable that a contour element touches two or three sides of the imaginary contour.

[0041] At least one fastening element can be arranged on a non-visible back side of the contour elements, in particular on the back side of the paving stone, in order to connect these contour elements to each other on their back sides. The back side of the contour elements does not necessarily have to face the underside of the paving stone.

[0042] Additionally or alternatively, at least one of the fastening elements can be arranged between at least two contour elements and can connect corresponding opposing side surfaces of adjacent contour elements.

[0043] The shape of at least one fastening element can be chosen arbitrarily. Geometric shapes and other forms are conceivable. Furthermore, a combination of fastening elements arranged on the back surfaces of the contour elements and fastening elements arranged on the side surfaces of the contour elements is conceivable.

[0044] The visible upper surface of the at least one fastening element can be positioned such that it is located below the upper surfaces of the existing contour elements. This allows the at least one fastening element to be covered by jointing and / or filling material. In this configuration, the paving stone according to the invention can be formed from several interconnected contour elements. A suitable mold could be used to create a one-piece paving stone that gives the impression of being composed of several contour elements connected by fastening elements.

[0045] Additionally or alternatively, it is conceivable that at least two contour elements are connected to each other without a fastening element. In this case, the side surfaces of adjacent contour elements can be connected to each other, whereby several contour elements can be combined to form a single overall contour element.

[0046] Additionally or alternatively, several contour elements can be arranged overlapping each other and connected to each other in the overlapping area, especially by material bonding.

[0047] Additionally or alternatively, the laying stone can have at least one base element to which contour elements and / or interconnected contour elements and / or overlapping contour elements are connected.

[0048] Additionally or alternatively, at least one of the fastening elements can be made of a different material than the contour elements. Advantageously, a paving stone according to the invention with contour elements and fastening elements can be lighter than a paving stone according to the invention with a base element to which the contour elements are connected.

[0049] Depending on a favorable design of the laying stone, at least one fastening element can be designed as a net-like structure and / or as a bridge.

[0050] The net-like structure can be arranged on the back of the contour elements and connect them to each other. Additionally or alternatively, the net-like structure can run around the outer surfaces of the outer contour elements and connect them to each other. The arrangement of the top surface of the net-like structure can be chosen so that it is not visible once installed and grouted.

[0051] A ridge can be an element of a net-like structure. Additionally or alternatively, several individual ridges can connect multiple contour elements. For example, one of the ridges can have the sinusoidal shape of the side and can be positioned at the edge. In this case, the ridge can define the shape of the side and connect contour elements at the edge to the edge and to each other. Regardless of its shape and arrangement, each ridge connects at least two contour elements. A contour element can also be connected to multiple contour elements via several ridges. The ridges can run between contour elements, with the arrangement of the top surfaces of the ridges chosen so that they are not visible when the tiles are laid and grouted.

[0052] In this arrangement, the upper surfaces of ribs and net-like structures are positioned below the upper surfaces of the contour elements. Additionally or alternatively, the ribs can run along the back surfaces of the contour elements. Furthermore, at least one fastening element arranged at the edge can additionally form a spacer for the paving stone according to the invention.

[0053] According to a favorable design of the paving stone, it can comprise at least two opposing contour elements. These contour elements can each be connected to one another via connecting areas on corresponding opposing side surfaces. Advantageously, the paving stone can be formed from directly connected contour elements. In this case, a mold can be designed such that the paving stone appears as if it were formed from several interconnected contour elements.

[0054] Additionally or alternatively, the laying stone can have at least two opposing contour elements which are arranged overlapping each other and are connected to each other at the overlap areas, in particular by a material bond.

[0055] Additionally or alternatively, contour elements can be connected to each other via fastening elements and / or by a base element.

[0056] In a favorable embodiment of the paving stone, it can comprise a base element whose cross-section, particularly its top surface, corresponds to the base area. The contour elements can be arranged on the base element, especially on its top surface, and can project from the top surface of the base element. The contour elements can have similar depths perpendicular to the top surface of the base element. The top surface of the base element can be completely concealed or covered by joints and / or filler material and / or by the contour elements. Each side of the base surface's outline can be contacted by at least two contour elements. Advantageously, a paving stone with a base element can be easily manufactured using drycast or wetcast methods. Furthermore, a paving stone with a base element can be easily laid.Furthermore, the sinusoidal shape of the sides can be easily achieved with a base element by shaping the side surfaces of the base element's body. The base element can also feature additional anti-slip features, such as grooves on an underside or lugs on side surfaces. Additionally, the base element can incorporate spacers that define a distance to adjacent paving stones and / or the outline of the base.

[0057] With a suitable design of the paving stone, the contour elements can be formed as a single unit with the base element. For example, a mold can be shaped to form the base element and the contour elements on its upper surface. Alternatively, the upper surface of the base element could be stamped, altering its shape to create multiple contour elements on the visible surface. This single-piece design allows the contour elements to be reliably and almost permanently attached to the base element.

[0058] Alternatively, the contour elements can be multi-part and each attached to and / or molded onto the base element. For example, the contour elements can be injection-molded onto the top surface. Furthermore, the contour elements can be applied or pressed onto the still-damp top surface of the base element and fixed in place as the top surface hardens. Bonding methods such as gluing the contour elements are also conceivable. Multi-part contour elements allow for more flexible configurations. The base element facilitates the easy implementation of the base's outline. This enables simple and reliable interlocking of the convex and concave curves of adjacent paving stones. It is also possible for the base to have additional areas besides the cross-section of the base element.For example, spacers can be arranged on the base element, forming sections of the outline.

[0059] With a well-designed paving stone, the contour elements can have different dimensions. This allows for the creation of interesting and natural-looking or organic-looking laying patterns that can blend into a natural environment.

[0060] With a suitable design of the paving stone, the contour elements can each have an outline divided into a number of imaginary secants of equal and / or different lengths. The outline of the contour elements can be the visible outer contour of the respective element from above. Such an outline allows for the creation of a natural-looking contour element. Furthermore, many different contour elements can be constructed using such outlines.

[0061] According to a further aspect of the invention, a paving stone bond with a plurality of paving stones is proposed, wherein several paving stones are designed as paving stones according to the invention. The paving stones can differ from one another, for example, in the shape of the contour elements and / or in the arrangement of the contour elements and / or in the number of periods of the sinusoidal profile on the sides.

[0062] Alternatively, identical paving stones can be used. This allows for several design options for a corresponding laying pattern. Additionally, it is possible to combine paving stones according to the invention with paving stones that have a visible surface without contour elements within the paving stone bond. The paving stones without contour elements can also have an outline with sides that have a sinusoidal profile. This allows these paving stones to be easily laid with paving stones according to the invention.

[0063] The advantages of the laying stones according to the invention have already been described and will not be repeated here.

[0064] Because the paving stones have an outline with sides with a sinusoidal profile, where the sine function for the sinusoidal profile on the sides can be the same sine function, the paving stones can be laid intuitively and easily and can easily interlock with each other.

[0065] Advantageously, the paving stones can be easily laid next to each other, with a convex deflection at the maximum of one paving stone engaging with a concave deflection at the minimum of an adjacent paving stone, and vice versa. The geometry with these deflections absorbs shear forces in at least two directions, thereby hindering or completely preventing slippage and / or rotation of the paving stones due to shear forces. This provides anti-rotation and anti-displacement protection, allowing vehicles to drive over a surface covered with such paving stones. Furthermore, many laying patterns can be implemented with these paving stones. In addition, a natural, organic laying pattern is achievable with these paving stones.

[0066] Since several contour elements are arranged within the base of the paving stone, laying a paving stone according to the invention advantageously creates the impression that many smaller stones or paving stones are laid at that location. Many interesting laying patterns can be advantageously created by selecting and arranging the contour elements.

[0067] Since the laying pattern includes both dummy joints between contour elements and joints between paving stones, the actual joint between the paving stones is no longer discernible. This allows for a more organic, natural, and / or wilder, less structured, and / or less constructed appearance of the laying pattern. Furthermore, by filling and / or planting vegetation in the spaces between the contour elements and the joints between the paving stones, it is no longer apparent that it is a single large paving stone with multiple contour elements. The impression can be created that several smaller paving stones are laid across the surface.

[0068] The contour elements can advantageously project vertically from the visible surface, thereby creating the impression of a natural path and / or square paved with stones or a path and / or square paved with cobblestones when several paving stones according to the invention are laid. The contour elements arranged within the base area can have different depths, thus creating paths and / or squares with an uneven surface. This surface can, for example, be less slippery when wet.

[0069] With a suitable design of the paving stone pattern, the paving stones can be laid in a rectangular, and especially a square, grid. This advantageously allows for simple planning of a surface covering.

[0070] In the following, a laying grid is understood to be a two-dimensional construct with which a surface can theoretically be covered. The laying grid is designed such that the outlines of adjacent laying grids abut each other without gaps. The laying grid comprises an area of ​​the cross-section of the paving stone or the base area of ​​the paving stone and half the laying distance to an adjacent paving stone. Since the cross-section or base area of ​​the paving stone and half the laying distance are taken into account in the laying grid, a floor covering and / or wall covering and / or ceiling covering and / or a paving stone bond and / or a surface pattern can be easily planned using this laying grid.

[0071] With a suitable design of the paving stone pattern, the paving stones can be arranged in their original position and / or rotated 90°, 180°, 270°, and / or 360° around a vertical axis relative to each other. This also changes the positions of the contour elements within the paving stone pattern, which can create a completely different visual impression. Rotating a paving stone can create the illusion that several different paving stones are arranged within the pattern. Furthermore, a more irregular laying pattern can be created. Additionally, different paving stones can be combined with each other within the paving stone pattern. drawing

[0072] Further advantages become apparent from the following description of the drawings. The drawings illustrate exemplary embodiments of the invention. The drawings, the description, and the claims contain numerous features in combination. A person skilled in the art will expediently consider the features individually and combine them into meaningful further combinations. They show, for example:

[0074] In the figures, similar or equivalent components are numbered with the same reference symbols. The figures merely show examples and are not to be understood as limiting.

[0075] The directional terminology used below, including terms like "left," "right," "above," "below," "in front," "behind," "after," and the like, serves only to improve the understanding of the figures and is in no way intended to limit their generality. The components and elements depicted, their interpretation, and their use may vary according to the considerations of a person skilled in the art and be adapted to the specific applications.

[0076] In the Figures 1 to 6 Various embodiments of a paving stone 100 according to the invention are shown. First, the similarities are discussed. The differences are then discussed.

[0077] As from the Figures 1 to 6As can be seen, a paving stone 100 according to the invention comprises a base surface 110, the outline 112 of which includes four sinusoidally extending sides 120. Furthermore, the paving stone 100 according to the invention comprises several contour elements 150, which are arranged within the base surface 110. In the illustrated embodiments, the contour elements 150 are arranged at least partially on a visible surface 102 of the paving stone 100 according to the invention.

[0078] For example, areas of the contour elements 150 can form the visible surface 102 or face the visible surface. Other areas of the contour elements 150 can face away from the visible surface 102 and not be visible. The outline 112 forms an envelope for the contour elements 150.

[0079] The paving stone 100 according to the invention can, for example, be made of concrete or another suitable material. It can be manufactured using a drycast or wetcast process.

[0080] The drycasting process can be a vibration-pressing process; for example, the concrete mix can be poured into a steel mold. For the wetcasting process, flowable concrete mixes can be poured into plastic molds, such as those made of polyurethane. These plastic molds can reproduce the finest textures, such as wood grain, and allow for the precise rendering of closely spaced edges of the contour elements. In the drycasting process, larger gaps between the contour elements are only possible due to the metal ribs in the mold.

[0081] The Figure 7 and 8show a paving stone arrangement 500 according to the invention with a plurality of such paving stones 100. Several paving stones 100 according to the invention can be, as shown Figure 8As can be seen, only the outlines 112 and the laying grid 510 of the paving stones 100 are shown, which are laid in rows and columns. The depicted paving stone pattern 500 has four rows with four paving stones 100 each. More or fewer paving stones 100 can also be laid in the paving stone pattern 500. In this case, a first side 121 of a paving stone 100 can interlock with a third side 123 of an adjacent paving stone 100 rotated by 0° or in its original position, and a second side 122 of a paving stone 100 can interlock with a fourth side 124 of an adjacent paving stone 100 rotated by 0° or in its original position.Furthermore, the depicted laying stones 100 can be rotated around the vertical axis to 90°, 180°, 270° or 360°, so that a first side 121 of a laying stone 100 can interlock with a first side 121 or a second side 122 or a third side 123 or a fourth side 124 of an adjacent laying stone 100.

[0082] It is also conceivable that paving stones 100 according to the invention are arranged in a paving stone bond 500 which are not rotationally symmetrical about 90°, 180°, 270° or 360° and accordingly cannot be rotated about the vertical axis z in order to interlock with other paving stones 100. The illustrated paving stone bond 500 comprises paving stones 100 which are arranged rotated about a vertical axis z by 90° and / or 180° and / or 270° and / or 360° relative to each other.

[0083] In an embodiment of the paving stone 100 according to the invention (not shown), the underside and the top side of the paving stone 100 can be used as the visible surface 102. The paving stone 100 can be rotated 180° about one of its horizontal axes x, y. This results in further variations of the laying pattern during installation. For example, the contour elements 150 on the top and underside of the paving stone 100 can be designed differently. The top and bottom surfaces can, for example, have different colors.

[0084] To create such a paving stone 100, the contour elements 150 can be connected to each other, for example, by overlaps or intersections 156. Alternatively, fastening elements 160 can be arranged between the contour elements 150 such that both a top and a bottom of the fastening elements 160 are located below the top and bottom surfaces of the contour elements 150, respectively, and are covered by filler material regardless of the orientation of the paving stone 100.

[0085] Figure 8 shows the laying grid 510 and the outline 112 of the laying stones 100 according to the invention of the laying stone bond 500. Figure 7 It can be seen that the paving stones 100 according to the invention are laid in a square laying grid 510. In an embodiment not shown, a rectangular laying grid 510 is also conceivable.

[0086] Because the laying stones 100 according to the invention have an outline 112 with sides 120 with a sinusoidal profile, wherein the sine function for the sinusoidal profile on the sides 120, 121, 122, 123, 124 is the same sine function in the illustrated embodiments of the laying stone 100 according to the invention, the laying stones 100 can be laid intuitively and easily and can easily interlock with adjacent laying stones 100 with the same outline 112.

[0087] In an alternative embodiment of the paving stone 100 according to the invention, not shown, each side 120, 121, 122, 123, 124 can have its own sinusoidal function for the sinusoidal path. Only sides 120, 121, 122, 123, 124 of adjacent paving stones 100 with the same sinusoidal function for the sinusoidal path can interlock with the corresponding side 120 of the other paving stone 100. Identical paving stones 100, or paving stones 100 with at least one side 120 having the same sinusoidal function for the sinusoidal path, can interlock with each other.

[0088] Two pages 120, 121, 122, 123, 124 or three pages 120, 121, 122, 123, 124 can also have the same sine function for the sinusoidal course.

[0089] The number of deflections 126, 128 of the sinusoidal curve of sides 120, 121, 122, 123, 124 of outline 112 can be chosen arbitrarily. A deflection 126, 128 is understood to be a convex deflection 128 or a concave deflection 126. In a sinusoidal curve with multiple deflections 126, 128, convex deflections 128 alternate with a maximum and concave deflections 126 with a minimum. The amplitude 125 of the sinusoidal curve can be chosen such that it periodically exhibits values ​​between a maximum value at the maximum and a minimum value at the minimum. In the illustrated embodiments, the magnitude of the maximum value of the amplitude 125 is equal to the magnitude of the minimum value of the amplitude 125. Here, constant maximum values ​​of the amplitude 125 can be chosen for the maximum values ​​at the maxima and constant minimum values ​​of the amplitude 125 for the minima.

[0090] In the in the Figures 1 to 7 In the illustrated embodiments of the laying stone 100 according to the invention, each side 120, 121, 122, 123, 124 has a convex deflection 128 and a concave deflection 126 and three turning points 129.

[0091] The in Figure 9 The fifth embodiment of the laying stone 100 according to the invention has an outline 112 with sides 120, 121, 122, 123, 124 with two convex deflections 128 and two concave deflections 126 and five turning points 129.

[0092] The in Figure 10 The sixth embodiment of the laying stone 100 according to the invention has an outline 112 with sides 120, 121, 122, 123, 124 with four convex deflections 128 and four concave deflections 126 and nine turning points 129.

[0093] The base area 110 of the fifth and sixth embodiments of the laying stone 100 is filled with contour elements 150 not shown.

[0094] In an embodiment of the paving stone 100 according to the invention (not shown), three convex deflections 128 and three concave deflections 126 are also conceivable. Furthermore, sinusoidal profiles with more than four convex deflections 128 and more than four concave deflections 126 are conceivable.

[0095] In a further embodiment of the paving stone 100 according to the invention, not shown, the paving stone 100 can have sides 120 with an unequal number of convex deflections 128 and concave deflections 126. For example, one side 120 can have only one concave deflection 126 or only one convex deflection 128; alternatively, the side 120 can have two concave deflections 126 and one convex deflection 128, or two convex deflections 128 and one concave deflection 126.

[0096] In a further embodiment of the paving stone 100 according to the invention (not shown), one side 120 can be longer than an adjacent side 120. Opposite sides 121, 123, 122, 124 are of equal length. The sinusoidal profiles of the sides 120 can have the same sine function. The longer sides 120 can have more periods and therefore more convex deflections 128 and / or concave deflections 126 than the narrower sides 120.

[0097] It is possible for two narrow sides 120 to interlock with one long side 120, or for two long sides to interlock with each other. Furthermore, an offset arrangement of the laying stones 100 according to the invention with several periods of the sinusoidal function of the sinusoidal course is conceivable.

[0098] As from the Figures 1 to 4 and 8 to 10As can be further seen, opposite sides 121, 123, 122, 124 of the outline 112 of the base 110 run parallel to each other. This results in convex deflections 128 and concave deflections 126 being arranged opposite each other. In the illustrated examples, sides 121, 123, 122, 124 each comprise a sinusoidal curve with one complete period of the sine function.

[0099] In a further embodiment not shown, of the laying stone 100 according to the invention, the sides 121, 123, 122, 124 can each comprise a sinusoidal profile with a multiple of a complete period of the sine function.

[0100] As from the Figures 1 to 4 and 8 to 10 As can be further seen, the sides 120 meet at corners 130 of the base 110, and the corners 130 form, as can be seen from the Figures 4 and 8As can be seen, the corners of a square 512. This square 512 forms the publisher grid 510.

[0101] In an alternative embodiment of the paving stone 100 according to the invention, not shown, the corners 130 can form the vertices of a rectangle. This is the case if two opposite sides 120 are longer than two other opposite sides 120 of the paving stone 100 according to the invention.

[0102] As from the Figures 1 to 4 and 8 to 10As can be further seen, inflection points 129 of opposing deflections 126, 128, in particular opposing amplitudes 125, meet at corners 130 of the base 110. Here, the period of the sinusoidal curve of a first side 121 starts at a corner 130 of the base 110 and runs to the opposite corner 130 of the base 110, where the period of the sinusoidal curve of the second side 122 starts. This sinusoidal curve also runs to the opposite corner 130, where the period of the sinusoidal curve of the third side 123 starts. This sinusoidal curve also runs to the opposite corner 130, where the period of the sinusoidal curve of the fourth side 124 starts. This sinusoidal curve also runs to the opposite corner 130, where the period of the sinusoidal curve of the first side 121 starts.

[0103] As from the Figures 1 to 7As can be further seen, the illustrated embodiments of the paving stone 100 according to the invention comprise contour elements 150, each of which has an outline 152 subdivided into a number of imaginary secants of equal and / or different lengths. The outline 152 of the contour elements 150 is the circumferential outer contour of the respective contour element 150 visible from above.

[0104] In an alternative embodiment of the paving stone 100 according to the invention, not shown, the contour elements 150 can have outlines 152 in the form of geometric shapes such as squares, rectangles, circles, ellipses, polygons, or combinations of geometric shapes, or the outline 152 can have a shape composed of several geometric shapes. Furthermore, the outlines 152 can be organically shaped. In addition, combinations of geometric and organic shapes are conceivable for the outlines 152.

[0105] As from the Figures 1 to 7 As can be further seen, the contour elements 150 are arranged on the visible surface 102 of the paving stone 100 according to the invention when laid in the intended state. The contour elements 150 form a contour element bond 200 with joints 210 between adjacent contour elements 150, in particular on the visible surface 102 of the paving stone 100 according to the invention.

[0106] This shows Figure 5 , like those in the Figures 1 to 3 The illustrated embodiments of the paving stone 100 according to the invention appear in the grouted state. The first, second, and third embodiments of the paving stone 100 according to the invention have the same contour element arrangement 200. Only the fixing of the contour elements 150 differs, at least partially, in these embodiments.

[0107] Figure 6 shows how the fourth, in Figure 4 The illustrated embodiment of the laying stone 100 according to the invention looks like this in the grouted state.

[0108] As from the Figures 1 to 7 As can be seen further, the contour elements have 150 different dimensions.

[0109] In an alternative embodiment not shown, the contour elements 150 can also have the same dimensions and / or orientations.

[0110] The first, in Figure 1 illustrated embodiment, the second, in Figure 2 illustrated, exemplary embodiment and the third, in Figure 3 The illustrated embodiment of the laying stone 100 according to the invention differs, among other things, from the one described in Figure 4 The fourth embodiment of the laying stone 100 according to the invention is distinguished by the number and arrangement of the contour elements 150.

[0111] The in the Figures 1 to 3The illustrated embodiments have the same contour element assembly 200, which comprises seventeen contour elements 150.

[0112] The in Figure 4 The illustrated embodiment has a contour element assembly 200, which comprises nineteen contour elements 150.

[0113] The number of contour elements (150) can be chosen arbitrarily, as long as they can be arranged within the outline (112). Furthermore, the elements differ in the Figures 1 to 3 illustrated embodiments of the Figure 4 The illustrated embodiment is achieved by the arrangement of the contour elements 150.

[0114] In an alternative embodiment not shown, the number and shape of the contour elements 150 can be identical in the embodiments, but the arrangement of the contour elements 150 on the base surface 110 can vary.

[0115] As from the Figures 1 to 3As can be further seen, at least one fastening element 160 connects at least two contour elements 150 to each other. In the Figure 1 and 3 The outline 112 of the base area 110 is an outline 112 formed by imaginary lines. Furthermore, the base area 110 is an imaginary surface.

[0116] As from the Figures 1 to 3 As can be further seen, the illustrated fastening elements 160, 162, 164, 166 are arranged between the contour elements 150 and connect side surfaces of adjacent contour elements 150 to each other.

[0117] As from the Figures 1 to 3As can be further seen, some fastening elements 160, 162 have a polygonal cross-section, with side surfaces of these fastening elements 160, 162 abutting side surfaces of the contour elements 150. A fastening element 160, 162 can connect up to four contour elements 150 together. Another fastening element 160, 164 is star-shaped and comprises several webs, each web abutting one of the contour elements 150 at one end. A further fastening element 160, 166 is a combination of the described fastening elements 162, 164 and, in the illustrated embodiment, has a polygonal cross-section from which a web projects.

[0118] In an embodiment not shown, of the laying stone 100 according to the invention, at least one of the fastening elements 160 can be additionally or alternatively arranged on an underside of the contour elements 150.

[0119] In a further embodiment of the laying stone 100 according to the invention, not shown, the at least one fastening element 160 can be designed as a net-like structure and / or as a web.

[0120] The bridge can have a rectangular cross-section and can connect several contour elements 150 to one another. The mesh-like structure can have several fastening elements 160 which connect the contour elements 150 to one another. The fastening elements 160 can be made of a different material than the contour elements 150.

[0121] In the in the Figures 1 to 3 In the illustrated embodiments of the laying stone 100 according to the invention, the contour elements 150 and the fastening elements 160, 162, 164, 166 are made of the same material in the same mold.

[0122] The in the Figure 1 and 2The illustrated embodiments of the paving stone 100 according to the invention each have a spacer 170 on one of the contour elements 150. This spacer also forms a section of the outline 112. The in Figure 3 The third embodiment of the laying stone 100 according to the invention, as shown, has no spacer 170 in contrast to the first embodiment and the second embodiment of the laying stone 100 according to the invention.

[0123] In the in the Figures 1 to 3 In the illustrated embodiments of the laying stone 100 according to the invention, at least two opposing contour elements 150 are connected to each other via connection areas 154 on corresponding opposing side surfaces.

[0124] In an alternative embodiment of the paving stone 100 according to the invention, not shown, the paving stone 100 can have connection areas 154 between the contour elements 150 instead of fastening elements 160, such that each contour element 150 contacts at least one other contour element 150. This allows the paving stone 100 according to the invention to be formed from contour elements 150 that contact each other and are thereby connected to one another.

[0125] In a further, alternative embodiment not shown, of the laying stone 100 according to the invention, the laying stone 100 can have contour elements 150 connected to each other exclusively by fastening elements 160.

[0126] The in Figure 3The illustrated embodiment of the laying stone 100 according to the invention has several opposing contour elements 150, which are arranged overlapping each other and are connected to each other at overlap areas 156.

[0127] In an alternative embodiment of the paving stone 100 according to the invention, not shown, the paving stone 100 can have overlapping areas 156 between the contour elements 150 instead of fastening elements 160, so that each contour element 150 overlaps with at least one other contour element 150. This allows the paving stone 100 according to the invention to be formed from overlapping and thereby interconnected contour elements 150.

[0128] If overlap areas (not shown) are selected between the paving stones 100 according to the invention, but no contour elements 150 are provided, empty contour element areas are created between two adjacent paving stones 100, which can be filled with jointing material. Alternatively, these areas can be planted with vegetation.

[0129] The in Figure 2 The second embodiment of the laying stone 100 according to the invention, as illustrated, differs from the one shown in Figure 1 and 3 The first and third embodiments of the paving stone 100 according to the invention are distinguished in that it has a base element 140, the upper surface of which corresponds to the base surface 110. The contour elements 150 are arranged on the base element 140, in particular on its upper surface.

[0130] As from Figure 2As can be further seen, the outline of the base element 140 forms the outline 112 of the base area 110 and the top of the base element 140 forms the base area 110.

[0131] As from the Figure 2 As can be further seen, in the illustrated embodiment, the contour elements 150 are formed in one piece with the base element 140. In an alternative embodiment not shown, the contour elements 150 can also be formed in multiple parts and can each be attached to and / or integrally formed with the base element 140.

[0132] In an alternative embodiment of the paving stone 100 according to the invention, not shown, the paving stone 100 can have the base element 140 instead of fastening elements 160, which reliably fixes the contour elements 150. Furthermore, a combination of touching or overlapping contour elements 150 and the base element 140 is conceivable.

[0133] The overlap areas 156, connection areas 154 and fastening elements 160 can be combined with each other and / or with a base element 140 as desired.

[0134] The in Figure 4 The fourth embodiment of the paving stone 100 according to the invention shows only a further exemplary contour element assembly 200. Some of the contour elements 150 shown are connected to each other via connection areas 154. The unconnected contour elements 150 can be connected to each other via a base element 140 (not shown) and / or via fastening elements 160 (not shown) and / or via overlap areas 156 (not shown) and / or via connection areas 154 (not shown).

[0135] In an alternative embodiment not shown, at least one of the contour elements 150 of the fourth embodiment can have spacers 170 at the edge.

[0136] Additionally or alternatively, the base element 140 of the second embodiment can have at least one spacer 170.

[0137] As from the Figures 1 to 4 As can be further seen, each side 120, 121, 122, 123, 124 of the outline 112 of the base 110 is touched by at least two contour element outlines 152.

[0138] The top surfaces of the fastening elements 160 and the top surface of the base element 140 are positioned below the top surfaces of the contour elements 150, allowing the fastening elements 160 and the base element 140 to be covered by jointing material.

[0139] For example, the distance between the visible surface 102, or between the top surfaces of the contour elements 150 and the top surfaces of the fastening elements 160, can be 25 mm. With contour elements 150 that are 70 mm deep, the fastening elements 160 would be 45 mm deep. Other distances and dimensions are also conceivable.

[0140] For example, the distance between the visible surface 102 or between the top surfaces of the contour elements 150 and the top surface of the base element 140 can be 25 mm. The contour elements 150 projecting from the top surface of the base element 140 can be 25 mm deep.

[0141] The contour elements 150 of the second embodiment can only be contours and / or top surfaces of a stone or paving stone. Depth is only required insofar as joints 210 can be formed between the contour elements 150.

[0142] In the illustrated embodiments, at least 75% of the base area 110 is filled or covered with contour elements 150. This creates the visual impression of a densely covered surface. Furthermore, interlocking the paving stones 100 according to the invention without a base element 140 can be facilitated if they have several contour elements 150. Additionally, the joints between the paving stones 100 can be better concealed if there are many contour elements 150 and thus many joints 210 between the contour elements 150.

[0143] The in Figure 7 The illustrated laying stone arrangement 500 comprises laying stones 100 according to the invention as shown in the Figures 1 to 3 illustrated embodiments or at least one of these embodiments and the one in Figure 4The fourth embodiment of the paving stone 100 according to the invention is shown. In this embodiment, the paving stones 100 are additionally rotated about the vertical axis z. Further combinations with other embodiments of the paving stone 100, which differ particularly in the contour element arrangements 200, would be conceivable.

[0144] In a further embodiment of the laying stone arrangement 500, not shown, only one embodiment of the laying stones 100 according to the invention can be laid.

[0145] Furthermore, a paving stone arrangement 500 is conceivable in which the paving stones 100 according to the invention are always arranged and aligned in the same way. The paving stone arrangement 500 can also comprise paving stones 100 with a base element 140, the cross-section of which forms the base surface 110 with the outline 112, but which does not have any contour elements 150 on its upper surface.
