Abstract

The invention relates to a floor covering element (2) with a square base form. An indentation (8.1, 8.2, 8.3, 8.4) is provided on all four base sides, each indentation being symmetrical in relation to a middle axis of symmetry (12). Opposite indentations are mirror images of each other. Each indentation is complementary to the indentations on the two base sides that are joined by a corner. A projection (24) is provided in each of the four corner areas of the floor covering element, this projection being essentially in the shape of a right-angled isosceles triangle or a surface element similar to such a triangle with bent sides. The removal of the four projections (24) results in a floor covering element of a second type (42) which can be laid together with other floor covering elements of the second type (42) or together with floor covering elements of the first type (2).

Description

Flooring element made of artificial stone material and flooring element set

The invention relates to a floor covering element of the first type

Artificial stone material,

1 characterized by the following features in combination: (a) The flooring element has a square as a basic shape with four

Base pages and four corners; (b) as it progresses along the perimeter of the

Floor covering elements are provided with a first base side with a first mink toothing, a second base side with a second toothing, a third base side with a third toothing and a fourth base side with a fourth toothing;

(c) each of the four gears is axisymmetric to one

Axis of symmetry, which passes through the bisection point of the relevant base side and is perpendicular to the base side concerned; (d) the first toothing and the third toothing are mirror images of one another, and the second toothing and the fourth toothing are mirror images of one another; (e) the first toothing is complementary to the second and fourth toothing, and the third toothing is complementary to the second and fourth toothing; (f) and at each of the four corner regions of the flooring element there is a projection which essentially has the shape of a right-angled, isosceles triangle or one of these

Triangle-like surface element with curved legs.

Floor covering elements with a square basic shape are known in considerable numbers.

The floor covering element according to the invention is technically advantageous in that - measured by the not particularly high standard of known floor covering elements with a square basic shape - the geometry of the first type of floor covering element and the formation of the toothing lead to the fact that floor covering elements of the first type can be created, which is a high

Load-bearing capacity (or in other words: a high level of security against unwanted floor covering element displacement under the effect of loads). The protrusions at the corner areas of the flooring element potentially have a double function; they increase the anchoring effect of the toothings and, in a further aspect of the invention to be found below, can bring about yet another technical aspect. The lively, appealing appearance of the dressing is also a positive aspect of the invention.

In the claims and in the description of the present text, statements about geometric relationships are made in many places, for example "toothing", "mirror image", "toothing formed from a line of straight, angularly adjoining ones Sections ". All such statements relate to a view of the floor covering element in plan view, ie a view from above of the useful side or top side of the floor covering element, as if this was laid on a base, unless expressly stated otherwise at the point in question The floor covering element according to the invention is preferably a floor covering element which is provided for the creation of floor coverings “in the outside area” or for the covering of areas outdoors

Called free, such as Areas for motor vehicle traffic, areas for bicycle traffic, areas for pedestrian traffic. Squares, courtyards, driveways, paths, streets, pedestrian zones, loading zones, terraces, parking areas for vehicles, petrol stations, commercial traffic areas, industrial traffic areas are particularly typical and preferred

Areas, workshops, container spaces.

In most cases, the "artificial stone material" is concrete. Brick-like materials may be mentioned as a further preferred possibility. In general, all materials are considered in which aggregates or fillers are embedded in time-dependent binders (e.g. also plastic), especially polymer concrete.

The protrusions are preferably each with a first part of their area outside their baseline square and with a second part of their area inside their baseline square. This is synonymous with the statement that the right angle is not with the right angle at the respective corner of the projections of the baseline square coincides, but is rotated relative to the right angle at the corner of the baseline square. In the case of the protrusions, the first part of their area is preferably smaller than the second part of their area. This is synonymous with the statement that the mentioned rotation of the protrusions relative to the relevant corner of the baseline square is a rotation by an angle different from 90 °.

The first and the third toothing preferably run continuously outside the first and the third, respectively

Baseline and the second and the fourth toothing run continuously throughout essentially within the second and the fourth

Baseline. Since the flooring elements of the first kind must be installed because of the geometry specified in the introductory paragraph in such a way that in the finished assembly there is a rotation of 90 ° from each flooring element to every adjacent flooring element, the above-mentioned development leads to the fact that as everyone progresses

Lay the installation joint laterally after each floor covering element length

"jumps". This "jumping" from the side increases the load capacity of the association very significantly, because it is no longer just the interlocking system for the mutual anchoring of the

Flooring elements of the first type is responsible.

Alternatively, however, it is also possible to design part of the toothings or all toothings so that they run partly outside and partly inside the relevant baseline.

Preferably, the first and the third toothing each have a recess with respect to a straight line which is that of the Connects distant ends of the square corners of the two protrusions of the relevant base side; and the second and the fourth toothing each have a projection opposite a straight line which connects the ends of the two overhangs of the relevant grand side which are remote from the square corners. The

Interlocking with a recess can at the same time be the "intermeshing running essentially outside the relevant baseline" mentioned above; the toothing with a protrusion can at the same time consistently and substantially the "toothing mentioned above" within the relevant

However, it is also possible to assign these features the other way round, that is to say, the toothing with a recess is straight to a toothing running within the relevant baseline and the toothing with a projection to a toothing running continuously outside the relevant baseline.

In the case of the first and the third toothing, the ends of the two projections which are distant from the corner of the square are preferably outside the base line square; and at the second and fourth toothing, the ends of the two overhangs, which are distant from the square corners, are located within the baseline square.

The first and the third toothing preferably each have only a single recess with respect to the straight line which connects the ends of the two projections of the relevant base line which are distant from the square corners; and the second and the fourth toothing each have only a single projection in relation to the straight line which is that of the square corners distant ends of the two supernatants of the relevant baseline.

The return (preferably the multiple returns, if present) preferably extends essentially up to the assigned baseline; and the protrusion (preferably the plurality of protrusions, if any) goes substantially to the associated baseline. However, it is alternatively possible that the recess does not go as far as the assigned baseline or continues beyond this baseline to the interior of the flooring element. It is alternatively also possible that the projection does not go as far as the assigned grand line or continues beyond the assigned base line.

In the case of the four supernatants, the one on the right is preferred

Angle-opposite projection base line essentially continues the course of a partial length of the toothing that adjoins a projection end.

It is pointed out that it is possible, if desired, to provide both a projection and a recess or several projections or several recesses on the straight line which connects the ends of the two projections of the base side in question which are remote from the square corners.

Each toothing is preferably a line of straight sections that adjoin one another at an angle, or a curved line or a line with at least one straight section and with at least one curved section. The curvature of the line can change gradually or abruptly in the course. Transitions of clockwise curvature and counterclockwise curvature are also preferred.

For each toothing, the partial length between the ends of the two protrusions distant from the square corners is preferably by two or three or four angularly adjoining, straight-line sections or by a curved line or by a line of at least two straight-line sections which extend over at least one curved section are connected.

The floor covering element of the first type is preferably provided with spacing projections on the circumference, the spacing projections not being taken into account when considering the geometric relationships mentioned in the entire previous description (and in claims 1 to 5). The latter half-sentence does not mean, however, that there are not versions in which, even when the spacing projections are taken into account, the geometric relationships mentioned are still given. The spacing projections can in particular be one size

Have narrow joints with a width of at most 5 mm between adjacent flooring elements, which simplifies the laying of the flooring elements. These "narrow" joints, which in most cases are 3 to 5 mm wide, are the joints that are normally used as laying joints between the

Floor covering elements are present in the floor covering and are normally filled with sand after the floor covering elements have been laid. If the flooring elements have these "small" spacing projections, the installer can more easily by laying Toasting the spacer tabs work. On the other hand, the spacing projections can in particular have a size for fixing wide joints with a width of at least 8 mm between adjacent floor covering elements, as a result of which powerful water passage joints are formed. If those

"Larger" spacer projections are provided, there are relatively wide joints between adjacent flooring elements. These joints are usually also filled with sand or grit. These "wide" joints allow rainwater to flow into the subsoil between the flooring elements much more effectively than with the "narrow joints of normal width", so that the occupied area no longer has to be connected to a drainage system and a contribution to the desired enrichment of the groundwater is made , Both with the "smaller" spacing projections and with the "larger"

Spacer projections can either be designed in such a way that the projections of a floor covering element in question come into contact with locations of the adjacent floor covering elements that are not provided with a projection there, or one can be designed such that the projections are laid at locations with the neighboring ones

Flooring elements come into contact where the latter also have a projection; in this case the projections collide in pairs. It is understood that in this case the projections have a "projection dimension" compared to the other flooring element contour, which is approximately half that desired

Joint width corresponds; in the first case described, the "projection dimension" of the projections must correspond approximately to the desired joint width. It is emphasized that the term "toothing" is only intended to express the function of the positive interlocking ens or the mutual anchoring in the installed state between two adjacent flooring elements. In particular, it should not be anything in the direction of sharpness, angularity or angled course of

Sections of the toothing are expressed; also a rounded course e.g. According to a sine line, a toothing is of course in the sense of the invention.

Another object of the invention is a flooring element of the second type made of artificial stone material, characterized in that it has a shape which results from the removal of the four protrusions of the previously described flooring element of the first type. "Removal of a supernatant" means removal along a line which essentially follows the course of the subsequent partial length of the relevant one

Gearing (between the ends of the two projections distant from the square corners) continues. This also includes a definition of the line from which the first type of flooring element is referred to as a protrusion. It is understood that all of the explanations and preferred features described above in connection with the

Floor covering element of the first type have been described, also apply to the floor covering element of the second type.

The second type of flooring according to the invention can alternatively also be provided by the presence of the following features in

Define combination:

(a) the flooring element has a non-square rectangle (ie a rectangle which has different lengths and widths) as a basic shape with four edge sides and four corners; (b) as it progresses along the circumference of the flooring element are a first edge side with a first toothing, a second edge side with a second toothing, a third edge side with a third toothing, and a fourth edge side with a fourth

Toothing provided;

(c) each of the four toothings is axially symmetrical to an axis of symmetry, which passes through the bisection point of the relevant front side and is perpendicular to the relevant base side;

(d) the first toothing and the third toothing are mirror images of one another, and the second toothing and the fourth toothing are mirror images of one another;

(e) the first toothing is complementary to a central portion of the second and fourth toothing, and the third toothing is complementary to the central portion of the second and fourth toothing.

The first and the third toothing are preferably located on the shorter sides of the base side rectangle and each have at least one recess (preferably only one recess) with respect to the base side rectangle; and the second and the fourth toothing are located on the longer sides of the base side rectangle and each have at least one projection (preferably only one projection) with respect to the base side rectangle.

Another object of the invention is a set of flooring elements, characterized in that it comprises flooring elements of the first type, as described above, and flooring elements of the second type, such as described above. The set of flooring elements consists of at least one type of flooring element and one type of flooring element.

If you lay the first type of flooring element and the second type of flooring element from the set of flooring elements, there are the following basic options: a) You change more or less regularly, e.g. but alternately, between a floor covering element of the first type and a floor covering element of the second type; b) You have a first covering area, which is covered with floor covering elements of the first type, and then a second covering area, which is covered with floor covering elements of the second type.

In the latter installation case arise between the

Floor covering elements of the second type of water passage openings which are at least essentially in the form of a small square. In the first-mentioned installation case, a water passage opening that is at least as large as one is created at every point where there is a corner point of a floor covering element of the second type

"removed supernatant" is. It is a special characteristic of the floor covering element set according to the invention that the floor covering elements of the first type can be placed against one another without any problems, that the floor covering elements of the second type can be placed against one another without any problems, and in particular that

Flooring elements of the second type can be easily applied to flooring elements of the first type. It is expressly emphasized that - going beyond the original formulation of claim 8 - the flooring element set according to the invention can also be constructed from flooring elements of the first type and flooring elements of the second type, each of which does not necessarily have all the features (a) to (f) of the originally formulated

Have claim 1. It is sufficient if there is a subset of the features (a) to (f). In particular, the axis symmetry according to feature (c) and / or the mirror image according to feature (d) and / or the complementarity according to feature (e), if it relates to only a part of the toothing, can be omitted. A preferred i

An example of a floor covering element of the first type, which is free from part of the restrictions of the original claim 1, is a floor covering element of the first type, in which each of the four toothings is intrinsically symmetrical or point-symmetrical, in which all toothings are rotated through 90 °, 180 ° or 270 ° around a virtual, upright, central axis of rotation can be brought into mutual alignment, and in which each toothing is complementary to the other three toothings. The same applies to the second type of flooring element.

Yet another object of the invention is a third type of flooring element made of artificial stone material, characterized in that it has a shape which is obtained by integrally integrating a plurality of first type flooring elements or a plurality of second type flooring elements.

Alternatively, it is also possible for the floor covering element of the third type to be integrally "mixed" at least one floor covering element of the first type and at least one floor covering element of the second type, e.g. B. a floor covering element of the first type and a floor covering element of the second type. Exactly two floor covering elements of the first type or two floor covering elements are preferably; or three flooring elements of the first type and three flooring elements of the second type; or even more flooring elements of the first kind or even more

Combine flooring elements of the second type with one another. When three flooring elements are combined, there is the possibility of combining "in series" or the possibility of combining "in an angular form", the latter being preferred.

The floor covering element of the third type preferably has at least one dummy joint in the useful side or top side. The dummy joint preferably runs essentially in accordance with the pair of teeth eliminated by the union.

The invention is explained in more detail below with reference to exemplary embodiments shown in the drawings. 1 shows a floor covering element of the first type in a top view; 2 shows a floor covering element of the second type in a top view;

Fig. 3 is a flooring in plan view, the

Flooring elements of the first type according to FIGS. 1 and

Floor covering elements of the second type according to FIG. 2 has been created; 4 shows another embodiment of a floor covering element of the first type in a top view; 5 shows another embodiment of a floor covering element of the second type in a top view; 6 shows a third type of floor covering element in plan view; Fig. 7 shows another embodiment of a third type of flooring element.

The floor covering element of the first type 2 shown in FIG. 1 has a square basic shape, which is illustrated by four main sides 4.1 to 4.4 drawn in broken lines, which meet at four corners 6. If one moves clockwise along the outline of the floor covering element 2, the first edge side 4.1 follows with a first toothing 8.1, the second edge side 4.2 with a second toothing 8.2, the third base side 4.3 with a third toothing 8.3, and the fourth side edge 4.4 with a fourth

Interlocking 8.4 on each other.

Each of the four toothings 8.1 to 8.4 is axisymmetric to an axis of symmetry, which is assigned by the bisecting point of the Grandside goes and is perpendicular to the relevant Grandside. This symmetry axis 10 is shown in the first toothing 8.1.

The first toothing 8.1 and the third toothing 8.3 are mirror images of one another or - in other words - axially symmetrical to one another with an axis of symmetry 12. The first toothing 8.1 is a line of angularly adjoining, straight-line sections 14.1 to 14.4, the second section 14.2 and the third section 14.3 are each considerably longer than the first section 14.1 or the fourth section 14.4. The second section 14.2 and the third section 14.3 each run at a smaller angle relative to the relevant side 4.1 than the first section 14.1 and the fourth section 14.4. Because of the mirror image of the axis 12, the third toothing 8.3 is also completely described.

The second toothing 8.2 is also a line with "kinks" and in itself axisymmetric to the axis of symmetry 10 '(which coincides with the axis of symmetry 12). Progressing clockwise in FIG. 1, the second toothing 8.2 has a first section 16.1, a second section 16.2, a third section 16.3 and a fourth section 16.4. The second section 16.2 and the third section 16.3 are each significantly longer than the first section 16.1 and the fourth section 16.4. The same applies to the angles relative to the relevant base line 4.2 as for the first toothing 8.1.

The fourth toothing 8.4 is a mirror image of the second toothing 8.2 or - in other words - axially symmetrical to the second toothing 4.2 with an axis of symmetry 12 'which corresponds to the Axis of symmetry 10 coincides. Because of this symmetry, the fourth toothing 8.4 is also completely described.

With the first toothing 8.1 and with the third toothing 8.3, all sections lie outside the relevant base line 4.1 or 4.3, so that two projections are formed relative to the relevant base line 4.1 or 4.3. If, on the other hand, one considers the relation to a straight connecting line 20 (drawn as a dotted line) between the ends 22 of the associated two projections 24, which are distant from the square corners 6 (which will be described in more detail below), only a single one results from the first toothing 8.1 Return 26 formed. The situation is analogous for the third toothing 8.3.

In the second toothing 8.2 all sections 16.1 to 16.4 are found within the relevant base line 4.2. There are two recesses 26 with respect to the second base line 4.2. In the case when one considers the straight line 28 (shown as a dotted line) between the ends 30 of the two associated projections 24 which are distant from the square corners 6, this line 28 is only a single one

Projection 32 formed.

It can be seen immediately that the first toothing 8.1 is complementary to both the second toothing 8.2 and the fourth toothing 8.4. In other words:

Another flooring element of the first type 2 can be applied to the drawn flooring element 2 from the right after rotation through 90 ° counterclockwise; Another flooring element of the second type can be rotated clockwise from the left by 90 ° be placed against the drawn flooring element 2. Another flooring element of the first type 2 can be applied from below against the drawn flooring element 2 after rotation through 90 °, either clockwise or counterclockwise, because the third toothing 8.3 is complementary to both the second toothing

8.2 and 8.4 to the fourth toothing. If in the second toothing 8.2 the second section 16.2 is extended to the left and the third section 16.3 is extended to the right, in each case up to the cut with the first toothing 8.1 or the third toothing 8.3 and drawn with a broken line 32, then i are outside the respective line 34 each have a surface element in the form of an isosceles, right-angled triangle. Each of these surface elements is called projection 24. The situation is quite similar with the fourth toothing 8.4.

A modification of the floor covering element 2 shown in FIG. 1 is easily conceivable, in which all "kinks" of the toothings are replaced by borders. Then each toothing is formed by a line consisting of straight sections and curved sections.

The floor covering element of the second type 42 shown in FIG. 2 can be most easily thought to have arisen by "cutting" the four projections 24 along the lines 34 in the floor covering element 2 of FIG. 1 and thereby removing them. As a result, the flooring element of the second type 42 has a very simple geometry, each with a triangular projection 44 on each longitudinal side and a recess 46 on each transverse side. The geometric relationships given in the introductory paragraph under (c), (d), (e) also apply for the flooring element of the second type 42, the word "complementary" now being understood in a somewhat modified meaning, which will be described in more detail later.

FIG. 3 shows in the right half a part 50 of a floor covering which is created from floor covering elements of the first type, and shows in the left half a part 52 of a floor covering which is created from floor covering elements 42 of the second type. The floor covering part 50 shows that the floor covering elements of the first type 2 are laid in alternating orientations in both the horizontal row direction and the vertical row direction, i.e. with a floor covering element 2 under consideration, a first toothing 8.1 may be at the top, then in all four floor covering elements 2 applied the second toothing 8.2 (or, which is synonymous, the fourth toothing 8.4) at the top in FIG. 3

Characteristic of the covering part 50, namely that if one walks along a horizontal laying joint 54 or a vertical laying joint 56, the laying joint "jumps" to the side after each floor covering element 2. This "jumping" increases the anchoring effect between the first type 2 flooring elements.

In the covering part 52 shown in the left half of FIG. 3, floor covering elements of the second type 42 are laid next to one another. Here too it can be seen that adjacent floor covering elements 42 are each turned through 90 °. Furthermore, you can also see a pronounced, lateral "cracking" of the laying joints. Because of the removed protrusions 24, the covering part 52 offers a completely different appearance compared to the covering part 50. In addition, water passage openings 58 are formed, each in the form of a small square and delimited by four adjacent second type 42 flooring elements.

It can be seen that in the second floor covering part 52, the "contact length" between two adjacent floor covering elements of the second type 42 is shorter than in the first floor covering part 50. On the long sides of the floor covering elements 42, only part of the projection 44 is used for toothing, while in the On the transverse side, the entire respective recess 46 is used for toothing.

It is particularly noteworthy how - at the border between the first covering part 50 and the second covering part 52 - the flooring elements of the second type 42 can be easily applied to the flooring elements of the first type 2, namely the recess 46 of a transverse side of a flooring element second type 42 against the projection of a fourth Teeth 8.4 of a Boderibelaglement element of the first type 2, and central part of a projection 44 of a longitudinal side of a floor covering element second

Type 42 against the recess of a first toothing 8.1 of a floor covering element of the first type 2.

It should be noted that the described problem-free application of flooring elements of the second type 42

Floor covering elements of the first type 2 can be used not only for the transition between a floor covering part 50 and another floor covering part 52, as shown in FIG. 3, but in particular that every second floor covering part 50 in FIG. 3 is used Can replace floor covering element of the first type 2 with a floor covering element of the second type 42 (alternatively, of course, also in a smaller or larger number, regularly scattered or irregularly scattered). If every second floor covering element of the first type 2 is replaced, water passage openings 58 are created which are the size of two protrusions 24 removed.

The floor covering element of the first type 2 shown in FIG. 4 has four toothings 8.1, 8.2, 8.3, 8.4, each of which has the shape of a curved line. Otherwise, the geometric relationships are the same as for the floor covering element 2 in FIG. 1. The "dividing lines" 34 shown as broken lines are now also curved as continuations of the respectively subsequent curved projection 32. The protrusions 24 are surface elements which are similar to the surface elements 24 from FIG. 1, but are curved

Have legs 60.

FIG. 5 shows a second type of floor covering element 42, which was created by removing the protrusions 24 from the first type 2 floor covering element of FIG. 4.

The floor covering elements 2 and 42 of FIGS. 4 and 5 can be laid quite analogously, as has been described with reference to FIG. 3. The water passage openings 58 then have a shape, similar to a small square, but with sides slightly rounded towards the inside of the square. FIGS. 4 and 5 also indicate how floor covering elements 2 and 42 with spacing projections 62 on the circumference can be imagined.

In Fig. 6, a third type of flooring element 70 is drawn, the one

Has shape that results from an integral union of four flooring elements of the first type 2, as shown in Fig. 1. The union is carried out in such a way that a floor covering element 70 with a square basic shape again results, but with a quadruple surface area. The floor covering element 70 has

Dummy joints 72, i.e. Grooves that extend from the upper side to a certain depth into the floor covering element 70, which run in accordance with the toothing pairs 8.1 / 8.2 etc. that have been eliminated by the combination of the floor covering elements of the first type. As a result, you have the optically with installed third type 70 flooring elements

Impression as if the area were covered with correspondingly smaller first-class flooring elements.

If you look at Fig. 3, right half, you can easily "cut out" other flooring elements of the third type, the z. B. are combined from two flooring elements of the first type or are combined from three flooring elements of the first type or are combined from four flooring elements of the first type. In the case of the combination of three flooring elements of the first type, either the arrangement "in series" or the arrangement "around the corner" or "in

To be able to occupy a surface, you have to use two different floor covering elements of the third type, namely one with a longitudinally oriented component (= floor covering element of the first type) and two transversely oriented components (= Floor covering elements of the first type), and the other floor covering element of the third type from two longitudinally oriented components and a transversely oriented component. When four flooring elements of the first type are combined, an embodiment in T-shape can be provided as an alternative to FIG. 6.

FIG. 7 shows a third type of flooring element 70 which has a shape which is formed by integrally combining two second type of flooring elements

42, as drawn in Fig. 2, has arisen. Here, too, there is a dummy joint 72, which runs in accordance with the pair of teeth eliminated by union i.

3, left half, it is also easy to imagine other third-type flooring elements made up of more than two second-type flooring elements.

It is emphasized that floor covering elements of the third type 70 also without the illustrated dummy joints 72, or with dummy joints that do not correspond to the toothing pairs which have been eliminated by the union. run, are possible.
