Abstract

The interlocking blocks possess, on at least two opposite sides (2, 3), outwardly tapering teeth (4, 5). On the front sides (9) of one side (3), the teeth (5) are provided with toothing tongues (10) and on the front sides (6) of the other side (2), the teeth (4) are provided with toothing grooves (8). In addition, the toothed flanks (11, 12) of one tooth row (5) possess distance projections (13). An interlocking block can be constructed, for example, as a rectangular block (1) and possess, on its longitudinal sides (2, 3), in each case three teeth (4, 5) and, on its narrow sides (14, 15), either a tongue (16) or a groove (17). <??>The interlocking blocks can be used either for constructing cycle paths with few unevenesses, the teeth locking into one another, or they can be used as lawn interlocking blocks, the teeth in each case abutting against one another and being locked by the toothing tongues (10) and toothing grooves (8). <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf Verbundsteine, wobei die Steine derart ausgebildet sind, dass sie sowohl als Fahrradstreifen als auch als Rasenverbundsteine Verwendung finden können. Es sind eine Vielzahl von Verbundsteinen bekannt, die für Gehwege oder befahrbare Plätze Verwendung finden und auch Rasenverbundsteine, die eine möglichst grosse Fläche für den Rasenwuchs aufweisen und andererseits eine genügende Verzahnung aufweisen, um beim Befahren durch Fahrzeuge nicht zu verrutschen.The present invention relates to composite stones, the stones being designed such that they can be used both as bicycle strips and as grass composite stones. A large number of composite stones are known, which are used for sidewalks or passable places, and also grass composite stones, which have the largest possible area for lawn growth and, on the other hand, have a sufficient toothing so that they do not slip when being driven over by vehicles.

Aus der DE-U-1 988 250 ist ein Verbundpflasterstein bekannt, der an mindestens zwei gegenüberliegenden Seiten nach aussen sich verjüngende Zähne aufweist. Dieser einfache Stein hat mehrere Nachteile. Einerseits erlaubt er keine Verwendung als Rasengitterstein und andererseits besteht bei solch einfachen Verzahnungen die Gefahr, dass sich die beiden ineinandergreifenden Teile verkeilen und damit das Verlegen erschweren, und dass das Regenwasser schlecht versickern kann.A composite paving stone is known from DE-U-1 988 250, which has teeth that taper outwards on at least two opposite sides. This simple stone has several disadvantages. On the one hand, it does not allow use as a grass paver, and on the other hand, with such simple toothing, there is a risk that the two interlocking parts wedge together and thus make laying more difficult, and that the rainwater can trickle away.

Aus der DE-U-1957 328 ist ein mit Durchbrüchen versehener Gitterstein bekannt, der als Rasengitterstein Verwendung findet, jedoch nicht als voller Verbundstein. Dieser vorbekannte Gitterstein weist an den Randstegen Federn oder Nuten auf, um im Verbund verlegt zu werden.DE-U-1957 328 discloses a grating stone provided with openings which is used as a grass grating stone, but not as a full composite stone. This previously known lattice stone has tongues or grooves on the edge webs in order to be laid together.

Es ist davon ausgehend Aufgabe der vorliegenden Erfindung Verbundsteine anzugeben, die ohne ineinander zu Verkeilen sowohl als volle Steine für beipielsweise Fahrradwege als auch als Rasenverbundsteine verwendet werden können und ein ebenmässiges Fugenbild ergeben. Diese Aufgabe wird mit den in den Ansprüche definierten Verbundsteinen gelöst.Based on this, it is an object of the present invention to provide composite stones which can be used as full stones for example bicycle paths and as lawn composite stones without wedging into one another and result in an even joint pattern. This problem is solved with the composite blocks defined in the claims.

Die Erfindung wird im folgenden anhand einer Zeichnung von Ausführungsbeispielen näher erläutert.

  • Die Figuren 1 und 2 zeigen einen Rechteckstein als erstes Ausführungsbeispiel in perspektivischer Sicht und jeweils um 180 Grad gedreht,
  • Figur 3 zeigt einen Stein gemäss den Figuren 1 oder 2 im verlegten Zustand mit umliegenden Steinen,
  • Figur 4 einen Schnitt gemäss der Linie IV-IV in Figur 3,
  • Figur 5 einen Schnitt gemäss der Linie V-V in Figur 3,
  • Figur 6 einen Schnitt gemäss der Linie VI-VI der Figur 3,

The invention is explained below with reference to a drawing of exemplary embodiments.
  • FIGS. 1 and 2 show a rectangular block as a first exemplary embodiment in a perspective view and in each case rotated by 180 degrees,
  • FIG. 3 shows a stone according to FIGS. 1 or 2 in the laid state with surrounding stones,
  • FIG. 4 shows a section along the line IV-IV in FIG. 3,
  • 5 shows a section along the line VV in FIG. 3,
  • FIG. 6 shows a section along the line VI-VI in FIG. 3,
  • FIG. 7 shows three composite blocks not laid completely in line to form a slight curve,
  • FIG. 8 shows an embodiment variant of the composite stone according to FIG. 1,
  • Figure 9 shows an average of two laid stones on uneven terrain and
  • FIG. 10 shows, as a further exemplary embodiment, a square composite stone together with a first composite stone when used as lawn stones.

In den Figuren 1 und 2 ist ein erster Stein, der Rechteckstein 1 dargestellt. Dieser Stein weist an den Längsseiten 2 und 3 je drei Zähne 4 bzw. 5 auf. Die Frontseiten 6 der einen Reihe von Zähnen 4 weisen je zwei Vorsprünge 7 auf, die zwischen sich eine Verzahnungsnut 8 bilden, während die Frontseiten 9 der anderen Reihe von Zähnen 5 je eine entsprechende Verzahnungsfeder 10 aufweisen. Wie aus den Figuren 1 und 2 deutlich hervorgeht, verjüngen sich die Zähne 4 und 5 nach aussen und dementsprechend erweitern sich komplementär dazu die durch die Flanken gebildeten Vertiefungen. In vorliegendem Beispiel weisen beide Flanken 11 und 12 der Reihe mit den Zähnen 5 je einen Abstandsnocken 13 auf. Anstatt die Abstandsnocken nur auf einer Seite vorzusehen, können diese je auf einer Zahnflanke, dafür an den Zähnen beider Seiten vorgesehen werden. Aus den Figuren 1 und 2 ist auch ersichtlich, dass sowohl die Vorsprünge 7 als auch die Verzahnungsfedern 10 sowie die Abstandsnocken 13 sich von unten her nicht über die volle Höhe des Verbundsteines erstrecken, so dass diese Teile im verlegten und gesandeten Zustand nicht sichtbar sind.A first stone, the rectangular stone 1, is shown in FIGS. 1 and 2. This stone has three teeth 4 and 5 on the long sides 2 and 3, respectively. The front sides 6 of one row of teeth 4 each have two projections 7, which form a toothing groove 8 between them, while the front sides 9 of the other row of teeth 5 each have a corresponding toothing spring 10. As can be clearly seen from FIGS. 1 and 2, the teeth 4 and 5 taper outwards and, accordingly, the recesses formed by the flanks expand in a complementary manner. In the present example, both flanks 11 and 12 of the row with teeth 5 each have a spacing cam 13. Instead of providing the spacer cams on one side only, they can be provided on one tooth flank, on the teeth on both sides. It can also be seen from FIGS. 1 and 2 that both the projections 7 and the toothing springs 10 and the spacing cams 13 do not extend from below over the full height of the composite block, so that these parts are not visible in the laid and sanded state.

Um einen vollständigen Verbund dieser Steine zu erzielen, weisen auch die Schmalseiten 14 und 15 Verzahnungselemente auf, wobei die Schmalseite 14 eine Feder 16 und die Schmalseite 15 eine der Feder entsprechende Nut 17 aufweist.In order to achieve a complete bond between these stones, the narrow sides 14 and 15 also have toothing elements on, the narrow side 14 having a tongue 16 and the narrow side 15 having a groove 17 corresponding to the tongue.

Teilweise in Figur 3 sowie in den Figuren 7 bis 9 ist dargestellt, wie solche Rechtecksteine als Verbundsteine verlegt werden können, beispielsweise zur Erstellung eines Radfahrstreifens. In Figur 3 erkennt man den vorgehend beschriebenen Rechteckstein 1 an dem oben rechts beispielsweise ein nicht ganz gezeichneter weiterer Rechteckstein 1 angefügt ist sowie in Figur 3 oben links ein weiterer Rechteckstein 18, der auf den zwei gegenüberliegenden Seiten nur je zwei Zähne 19 aufweist sowie die Feder 16 und Nut 17. Bei dieser Verlegeart in Verbundweise üben die Verzahnungsnuten und -federn die gleiche Funktion wie die Abstandsnocken aus, um zu verhindern, dass sich die Zähne ineinander verkeilen, und damit sich ein ebenmässiges Fugenbild ergibt. Ausgehend von den beiden Rechtecksteinen 1 und 18 ist es selbstverständlich auch denkbar, Rechtecksteine mit eventuell mehr Zähnen vorzusehen.Partly in FIG. 3 and in FIGS. 7 to 9 it is shown how such rectangular stones can be laid as composite stones, for example for creating a bicycle lane. In FIG. 3, the previously described rectangular block 1 can be seen, to which, for example, a further rectangular block 1, not shown, is added, as well as in FIG. 3, a further rectangular block 18, which has only two teeth 19 on each of the two opposite sides and the spring 16 and groove 17. With this type of installation in a composite manner, the toothing grooves and springs perform the same function as the spacer cams to prevent the teeth from wedging into one another and thus resulting in an even joint pattern. Starting from the two rectangular stones 1 and 18, it is of course also conceivable to provide rectangular stones with possibly more teeth.

In Figur 7 ist dargestellt, dass man durch leichtes Verkanten der Steine eine Kurve verlegen kann, die ja bei Fahrradwegen nicht sehr eng sein darf. In Figur 8 sind als Ausführungsvariante zwei Steine 20 dargestellt, die zu diesem Zwecke nicht genau rechteckig sondern leicht trapezförmig ausgebildet sind, wobei die zwei Längsseiten nicht streng parallel zueinander sondern leicht konvergent ausgebildet sind, und wobei die Schmalseite 21 mit der Feder 16 etwas breiter ist als die Schmalseite 22 mit der Nut 17. Sonst ist der Stein 20 gleich gestaltet wie der Stein 1, erlaubt jedoch durch seine Konizität ein Verlegen in Kurven. Um die Uebergänge zwischen den einzelnen Steinen möglichst eben zu gestalten, weisen die Kanten, insbesondere diejenigen der Frontseiten der Zähne eine Abfasung 21 auf, siehe Figuren 4, 5 und insbesondere 9.In Figure 7 it is shown that by slightly tilting the stones you can lay a curve, which must not be very narrow on bike paths. In Figure 8, two stones 20 are shown as a variant, which are not exactly rectangular but slightly trapezoidal for this purpose, the two long sides not being strictly parallel to one another but slightly convergent, and the narrow side 21 with the spring 16 being somewhat wider than the narrow side 22 with the groove 17. Otherwise, the stone 20 is designed in the same way as the stone 1, but due to its taper allows it to be laid in curves. In order to make the transitions between the individual stones as flat as possible, the edges have, in particular those of the front sides of the teeth have a chamfer 21, see FIGS. 4, 5 and in particular 9.

In der Figur 3 unten sowie in der Figur 10 ist eine zweite Verwendungsart der Verbundsteine dargestellt, als Rasenverbundstein. Zu diesem Zwecke stossen die Steine nur mit den Frontseiten der Zähne zusammen und bilden zwischen sich Oeffnungen 22, die mit Humus ausgefüllt werden können und mit Rasen bepflanzbar sind. Hier erfolgt die Verzahnung mittels der Verzahnungsnuten 8 sowie der Verzahnungsfedern 10 an den Frontseiten der Zähne sowie über die Federn 16 und Nuten 17 an den Schmalseiten der Steine.In FIG. 3 below and in FIG. 10, a second type of use of the composite stones is shown, as a lawn composite stone. For this purpose, the stones only collide with the front of the teeth and form openings 22 between them, which can be filled with humus and planted with lawn. Here, the toothing is carried out by means of the toothing grooves 8 and the toothing springs 10 on the front sides of the teeth and via the springs 16 and grooves 17 on the narrow sides of the stones.

In Figur 10 ist ein weiteres Ausführungsbeispiel durch den quadratischen Stein 23 dargestellt, der an allen vier Seiten je drei Zähne mit den Verzahnungsfedern und -nuten sowie den Abstandsnocken aufweist. Als weiteres Ausführungsbeispiel ist in Figur 10 der Rechteckverbundstein 24 dargestellt, der an seinen Schmalseiten je zwei Zähne 4 und 5 aufweist, die mit den gleichen Verzahnungsnuten und -federn und Abstandsnocken versehen sind wie die Zähne von Stein 1.In Figure 10, another embodiment is shown by the square stone 23, which has three teeth on all four sides with the toothing springs and grooves and the spacing cams. As a further exemplary embodiment, the rectangular composite block 24 is shown in FIG. 10, which has two teeth 4 and 5 on its narrow sides, which are provided with the same toothing grooves and springs and spacing cams as the teeth of block 1.

Bei der Verwendung der oben beschriebenen Verbundsteine ist es möglich, an geeigneten Stellen der Steine Oeffnungen vorzusehen, um den bepflanzbaren oder begrünbaren Anteil zu erhöhen. Andererseits ist es möglich, in den für die Begrünung gedachten Oeffnungen bei Bedarf Füllsteine, beispielsweise mit einer anderen Farbe zu Markierungszwecken oder dergleichen, vorzusehen. Ausserdem können sowohl die Füllsteine als auch die Verbundsteine eine Oberflächenstruktur wie Längs- oder Querrillen aufweisen.When using the composite stones described above, it is possible to provide openings at suitable locations of the stones in order to increase the proportion that can be planted or planted. On the other hand, it is possible, if necessary, to provide filler stones, for example with a different color for marking purposes or the like, in the openings intended for greening. In addition, both the filler stones and the composite stones can have a surface structure such as longitudinal or transverse grooves.

Solche Füllsteine können beispielsweise als Markierungen für Fahrradwege verwendet werden. Neben verschiedener Färbung können die Verbundsteine dabei vor Kreuzungen und dergleichen wie Rasensteine, d. h. Frontseite an Frontseite, verlegt und verschiedenfarbige und/oder leicht bombierte Füllsteine in die Oeffnungen gelegt werden, um erhöhte Aufmerksamkeit zu signalisieren.Such filler stones can be used, for example, as markings for bicycle paths. In addition to various Coloring, the composite stones can be laid in front of intersections and the like like lawn stones, ie front to front, and differently colored and / or slightly cambered filler stones can be placed in the openings in order to signal increased attention.
