Abstract

A ground covering comprising releasably coupled-together hexagonal panels (1, 1a, 1b) which alternately exhibit, on their hexagon sides, hook protrusions (5) and eyelet protrusions (7) for the coupling is designed such that it does not exhibit openings either within the panels in the region of the eyelet protrusions (7) or between the panels in the region of the mutually abutting corners (3). The panels border one another in an essentially gap-free manner over the entire length of their side surface, the rounding-off radii (R1, R2) towards the panel upper side being dimensioned such that they do not hinder the pivoting movement for the coupling of the hook protrusions. Consequently, an essentially opening-free and gap-free ground covering, which is suitable as a walk-on traffic surface area, can be provided. <IMAGE>

Description

Die Erfindung betrifft einen Bodenbelag aus lösbar gekoppelten sechseckigen Platten von der im Oberbegriff des Anspruchs 1 angegebenen Art.The invention relates to a floor covering made of releasably coupled hexagonal plates of the type specified in the preamble of claim 1.

Ein Bodenbelag dieser Art ist aus DE-A-29 32 241 bekannt. Er ist insbesondere zur schnellen bzw. behelfsmäßigen Verlegung von Fahrbahnen, Rollbahnen od.dgl. bestimmt. Bei dem bekannten Belag sind die Kopplungsvorsprünge so ausgebildet, daß die gekoppelten Platten in den Eckbereichen nicht aneinander stoßen, sondern sternförmige Ausnehmungen freilassen. Ferner sind in den Platten selbst drei an der Oberseite offene Ausnehmungen vorgesehen, die jeweils einen Steg einer Öse begrenzen. Die Folge ist, daß der Bodenbelag keine durchgehend geschlossene Fläche bildet, sondern von einer Vielzahl relativ großer Öffnungen unterbrochen ist. Bei Verwendung des Bodenbelages als Fahr- oder Rollbahn, insbesondere auch für militärische Zwecke, ist dies akzeptabel. Fur eine Verwendung als begehbare Verkehrsfläche, insbesondere im zivilen Bereich, ist der bekannte Bodenbelag aber nicht geeignet, da die zahlreichen relativ großen Öffnungen Stolperfallen, insbesondere für Damenschuhabsätze, darstellen.A floor covering of this type is known from DE-A-29 32 241. It is particularly suitable for quick or makeshift laying of roadways, taxiways or the like. certainly. In the known covering, the coupling projections are designed in such a way that the coupled plates do not abut one another in the corner regions, but rather leave open star-shaped recesses. Furthermore, three recesses open at the top are provided in the plates themselves, each of which delimit a web of an eye. The result is that the floor covering does not form a continuously closed surface, but is interrupted by a large number of relatively large openings. This is acceptable if the flooring is used as a runway or taxiway, especially for military purposes. However, the known floor covering is not suitable for use as a walk-in traffic area, particularly in the civilian sector, since the numerous relatively large ones Openings are tripping hazards, especially for women's shoe heels.

Entsprechendes gilt von gleichartigen Bodenbelägen, die aus DE-A-26 35 713, DE-A-31 25 690 und DE-A-34 03 989 bekannt sind und die ebenfalls Öffnungen sowohl innerhalb jeder Platte als auch in den Eckbereichen zwischen jeweils drei aneinandergrenzenden Platten aufweisen.The same applies to similar floor coverings, which are known from DE-A-26 35 713, DE-A-31 25 690 and DE-A-34 03 989 and which also have openings both within each plate and in the corner areas between three adjacent ones Have plates.

Der Erfindung liegt die Aufgabe zugrunde, einen Bodenbelag der genannten Art, ohne Beeinträchtigung seiner leichten Verlegbarkeit, so auszubilden, daß er eine als Gehfläche geeignete, im wesentlichen durchgehend glatte Oberfläche bildet.The invention has for its object to form a floor covering of the type mentioned, without impairing its ease of installation, so that it forms a substantially continuous surface suitable as a walking surface.

Die erfindungsgemäße Lösung der Aufgabe ist im Kennzeichen des Anspruchs 1 angegeben. Die Unteransprüche beziehen sich auf weitere vorteilhafte Ausgestaltungen der Erfindung, die insbesondere eine klemmfreie Kopplung der Platten gewährleisten sollen.The achievement of the object is specified in the characterizing part of claim 1. The subclaims relate to further advantageous refinements of the invention, which are to ensure, in particular, a clamp-free coupling of the plates.

Eine Ausführungsform der Erfindung wird anhand der Zeichnungen näher erläutert. Es zeigt:

  • Fig. 1 eine Draufsicht auf eine Platte des erfindungsgemäßen Bodenbelags;
  • Fig. 2 eine Draufsicht auf drei miteinander gekoppelte Platten des Bodenbelags;
  • Fig. 3 und 4 vergrößerte Detailschnitte entlang der Schnittlinien A-A und B-B von Fig. 2;
  • Fig. 5 und 6 Schnittdarstellungen entsprechend Fig. 3 und 4 zur Veranschaulichung der Schwenkbewegung beim Ankoppeln einer Platte.
An embodiment of the invention is explained in more detail with reference to the drawings. It shows:
  • Figure 1 is a plan view of a plate of the floor covering according to the invention.
  • Figure 2 is a plan view of three panels of the floor covering coupled together;
  • 3 and 4 enlarged detail sections along the section lines AA and BB of Fig. 2;
  • 5 and 6 are sectional views corresponding to FIGS. 3 and 4 to illustrate the pivoting movement when coupling a plate.

Die in Fig. 1 dargestellte Platte 1 hat die Form eines gleichseitigen Sechsecks, dessen Ecken mit 3 bezeichnet sind. An jeder Sechseckseite zwischen zwei Ecken 3 ist im mittleren Bereich ein Kopplungsvorsprung 5,7 ausgebildet. An drei nichtbenachbarten Seiten der Platte 1 ist der Kopplungsvorsprung 5 als ein Hakenvorsprung mit einem nach oben offenen Hakenprofil 9 ausgebildet, wie aus Fig. 4 ersichtlich. An den drei anderen Seiten sind die Kopplungsvorsprünge 7 als Ösen für den Eingriff eines Hakenvorsprungs 5 ausgebildet, wie in Fig. 4 für den Ösenvorsprung 7 einer angrenzenden Platte 1a dargestellt. Wie aus Fig. 4 ersichtlich, bildet der Ösenvorsprung 7 einen nach unten vorspringenden und abgerundeten Steg 11, der von dem Hakenprofil 9 unter- und hintergriffen wird. Von der Platte 1a ist der Steg 11 durch eine Ausnehmung 13 getrennt, die das Hakenprofil 9 aufnimmt. Die Ausnehmung 13 ist zur Oberseite der Platte 1a hin durch eine Wand 16 verschlossen, so daß die Platte 1a eine auch im Bereich des Kopplungsvorsprungs 7 durchgehende, öffnungsfreie Oberfläche bildet.The plate 1 shown in Fig. 1 has the shape of an equilateral hexagon, the corners of which are denoted by 3. On each side of the hexagon between two corners 3, a coupling projection 5, 7 is formed in the central region. On three non-adjacent sides of the plate 1, the coupling projection 5 is designed as a hook projection with an upwardly open hook profile 9, as can be seen from FIG. 4. On the three other sides, the coupling projections 7 are designed as eyes for the engagement of a hook projection 5, as shown in FIG. 4 for the eye projection 7 of an adjacent plate 1a. As can be seen from FIG. 4, the eyelet projection 7 forms a downwardly projecting and rounded web 11, which the hook profile 9 engages under and behind. The web 11 is separated from the plate 1 a by a recess 13 which receives the hook profile 9. The recess 13 is closed to the top of the plate 1a by a wall 16 so that the Plate 1 a also forms a continuous, opening-free surface in the area of the coupling projection 7.

Fig. 2 zeigt drei miteinander gekoppelte Platten 1,1a,1b. Ein Hakenvorsprung 5 (gestrichelt angedeutet) der Platte 1 greift unter einen Ösenvorsprung 7 der Platte 1a. Ebenso greift ein Hakenvorsprung 5 der Platte 1a unter einen Ösenvorsprung 7 der Platte 1b. Dabei sind die Kopplungsvorsprünge 7,5 so gestaltet, daß jeweils benachbarte Platten 1,1a bzw. 1a,1b auf der ganzen Länge ihrer Seitenfläche mit sehr geringem Spalt aneinanderliegen, wobei insbesondere auch im Bereich der drei zusammenstoßenden Ecken 3 nur ein sehr kleiner Spalt vorhanden ist. Dieses enge Aneinanderliegen der Platten wird u.a. dadurch erreicht, daß oberhalb jedes Hakenvorsprunges 5 die Seitenfläche der Platte zurückgesetzt ist, so daß sie eine Ausnehmung 13 bildet, (vgl. Fig. 1), die so geformt ist, daß sie den Ösenvorsprung 7 der jeweils anzukoppelnden Platte aufnimmt. Durch diese Maßnahme wird auch erreicht, daß die von dem Steg 11 des Ösenvorsprungs 7 definierte Drehachse 15 (Fig. 4), um die die Platte 1 mit dem Hakenvorsprung 5 beim Einkoppeln geschwenkt werden muß, im wesentlichen durch die Ecken 3 der Platte verläuft. Dies trägt dazu bei, daß die gekoppelten Platten mit sehr geringem Spalt aneinander anliegen können, ohne daß eine die Schwenkbewegung für das Einkoppeln behindernde Klemm- oder Keilwirkung eintritt.Fig. 2 shows three coupled plates 1,1a, 1b. A hook projection 5 (indicated by dashed lines) of the plate 1 engages under an eyelet projection 7 of the plate 1a. Likewise, a hook projection 5 of the plate 1a engages under an eyelet projection 7 of the plate 1b. The coupling projections 7.5 are designed such that adjacent plates 1, 1 a and 1 a, 1 b lie along the entire length of their side surface with a very small gap, in particular in the area of the three colliding corners 3 there is only a very small gap is. This close abutment of the plates is achieved, inter alia, by the fact that above each hook projection 5 the side surface of the plate is set back so that it forms a recess 13 (see FIG. 1), which is shaped so that it has the eyelet projection 7 of the respective plate to be coupled. This measure also ensures that the axis of rotation 15 (FIG. 4) defined by the web 11 of the eyelet projection 7, about which the plate 1 with the hook projection 5 has to be pivoted during coupling, runs essentially through the corners 3 of the plate. This contributes to the fact that the coupled plates can lie against one another with a very small gap, without a clamping or wedge effect which impedes the pivoting movement for the coupling.

Zur Erzielung einer klemmfreien Koppelbewegung trägt auch die Bemessung des Abrundungsradius bei, mit der die Oberfläche der Platte in die Seitenflächen übergeht. Diese Radien sind erfindungsgemäß an den mit Hakenvorsprüngen 5 versehenen Seitenflächen kleiner als an den mit Ösenvorsprüngen 7 versehenen Seitenflächen. An einer mit Ösenvorsprung 7 versehenen Seitenfläche ist ein Abrundungsradius R₂ vorgesehen, und zwar sowohl im Bereich des Kopplungsvorsprungs 5 als auch beiderseits davon, wie in Fig. 1 angedeutet, wobei dieser Abrundungsradius R₂ ausreichend groß bemessen ist, um eine Schwenkung der angrenzenden Platte zu ermöglichen, wie dies in Fig. 5 und 6 dargestellt ist. Dagegen hat an einer mit Hakenvorsprung 5 versehenen Seite der Abrundungsradius einen Wert R₁, und zwar sowohl im Bereich der an den Hakenvorsprung 5 angrenzenden Ausnehmung 13 als auch beiderseits davon, wobei dieser Radius R₁ sehr klein gewählt werden kann und hauptsächlich fertigungstechnisch bedingt ist. In praktischen Fällen kann z.B. der Radius R₂ den Wert 8 mm und der Radius R₁ den Wert 2,5 mm haben. In weiterer Ausbildung kann im unmittelbaren Bereich jeder Ecke 3 ein Abrundungsradius R₃ verwendet werden (vgl. Fig. 1), der noch kleiner als der Radius R₁ ist. Es ergibt sich also die Beziehung R₃ ≦ R₁ ≦ R₂.The dimensioning of the rounding radius with which the surface of the plate merges into the side surfaces also contributes to achieving a jamming-free coupling movement. According to the invention, these radii are smaller on the side surfaces provided with hook projections 5 than on the side surfaces provided with eyelet projections 7. On a side surface provided with eyelet projection 7, a radius of curvature R₂ is provided, both in the area of the coupling protrusion 5 and on both sides thereof, as indicated in FIG. 1, this radius of curvature R₂ being sufficiently large to allow the adjacent plate to pivot as shown in FIGS. 5 and 6. In contrast, on a side provided with hook projection 5, the radius of curvature has a value R 1, both in the area of the recess 13 adjacent to the hook projection 5 and on both sides thereof, this radius R 1 being able to be chosen to be very small and mainly due to production technology. In practical cases e.g. the radius R₂ has a value of 8 mm and the radius R₁ has a value of 2.5 mm. In a further training, a radius of curvature R₃ can be used in the immediate area of each corner 3 (see. Fig. 1), which is even smaller than the radius R₁. So there is the relationship R₃ ≦ R₁ ≦ R₂.

Jede Platte 1,1a usw. ist vorzugsweise als Kunststofformteil z.B. durch Spritzgießen hergestellt und besteht aus einer oberen Membran 21 und seitlichen Schürzen 23 und eventuell zusätzlichen Versteifungsrippen 27. Die Oberseite der Platte kann eine geeignete Profilierung zur Verbesserung der Rutschfestigkeit haben, wie in Fig. 1 durch das Rautenmuster 27 angedeutet. Die zwischen benachbarten gekoppelten Platten verbleibenden Spalte sind in den Fig. 2 bis 6 übertrieben groß dargestellt. Tatsächlich ist es möglich, die Platten im Rahmen der Fertigungstoleranzen praktisch spaltfrei, d.h. mit gegenseitiger Berührung aneinandergrenzen zu lassen, ohne daß die für das Einkoppeln nötige Verschwenkung durch Klemmwirkung behindert wird.Each plate 1,1a etc. is preferably made as a plastic molding, for example by injection molding, and consists of an upper membrane 21 and side skirts 23 and possibly additional stiffening ribs 27. The top of the plate can have a suitable profile to improve the slip resistance, as indicated in FIG. 1 by the diamond pattern 27. The gaps remaining between adjacent coupled plates are shown exaggeratedly large in FIGS. 2 to 6. In fact, it is possible to allow the plates to adjoin one another practically without gaps, ie with mutual contact, within the scope of the manufacturing tolerances, without the pivoting required for the coupling being impeded by the clamping action.
