Description

Die Erfindung bezieht sich auf einen Belag zur Ausbesserung ausgetretener Treppenstufen gemäß dem Oberbegriff des Patentanspruches 1. Ein derartiger Belag ist aus dem DE-GM 84 07 239 bekannt. Es handelt sich hierbei um ein einstückiges, L-förmiges Profil aus Kunststoff, das mit einer Füllkleber-Spachtelmasse auf die zu sanierende Treppenstufe aufgeklebt wird.The invention relates to a covering for repairing worn stairs according to the preamble of claim 1. Such a covering is known from DE-GM 84 07 239. It is a one-piece, L-shaped profile made of plastic, which is glued onto the step to be renovated with a filler adhesive filler.

Der dabei verwendete Kunststoff, wie z.B. Polyurethan, muß für den vorgesehenen Einsatzzweck hochstabil sein, insbesondere hinsichtlich Stoß- und Abriebfestigkeit. Die hierfür in Frage kommenden Polyurethan-Kunststoffe haben jedoch ein hohes spezifisches Gewicht und sind relativ teuer. Auch hat sich herausgestellt, daß die Verklebung mit der Treppe nicht sicher ist.The plastic used, such as Polyurethane must be highly stable for the intended use, especially with regard to shock and abrasion resistance. The polyurethane plastics in question, however, have a high specific weight and are relatively expensive. It has also been found that gluing to the stairs is not safe.

Die DE-C-964 983 beschreibt eine ebene Fußbodenplatte aus Holzfasern, Sperrholz, Hartpappe oder dgl. mit aufgeklebtem Gummibelag, der auch die Schmal- oder Stoßseiten der Platten bedeckt. Um zu verhindern, daß Wasser in das Holz eindringt, ist der Gummibelag zusätzlich so ausgebildet, daß er beispielsweise durch Überlappung oder Verzahnung eine formschlüssige Verbindung mit den Nachbarplatten eingeht.DE-C-964 983 describes a flat floor panel made of wood fibers, plywood, hard cardboard or the like with a glued-on rubber covering, which also covers the narrow or butt sides of the panels. In order to prevent water from penetrating into the wood, the rubber covering is additionally designed such that it forms a positive connection with the neighboring panels, for example by overlapping or toothing.

Aufgabe der vorliegenden Erfindung ist es, den Belag der eingangs genannten Art dahingehend zu verbessern, daß seine Verbindung mit den auszubessernden Trittstufen sicherer ist und die Montage erleichtert wird.The object of the present invention is to improve the covering of the type mentioned at the outset in such a way that its connection to the treads to be repaired is safer and the assembly is facilitated.

Diese Aufgabe wird durch die im kennzeichnenden Teil des Patentanspruches 1 angegebenen Merkmale gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.This object is achieved by the features specified in the characterizing part of patent claim 1. Advantageous refinements and developments of the invention can be found in the subclaims.

Aufgrund der relativ rauhen Oberfläche der Preßspanplatte ist die Klebeverbindung mit der auszubessernden Treppenstufe sehr viel sicherer geworden. Weiterhin wird durch das geringere spezifische Gewicht der Preßspanplatte gegenüber dem Polyurethan der Belag deutlich leichter, was natürlich auch die Montagearbeit erleichtert sowie die Transportkosten senkt. Hervorzuheben ist auch noch, daß die Kosten für die Herstellung des Belages deutlich reduziert werden, da pro Belag für eine auszubessernde Treppenstufe ca. 2 kg Polyurethan eingespart werden und durch die deutlich billigere Preßspanplatte ersetzt werden. Trotz dieser Maßnahme ist die Festigkeit (auch Kerbschlagzähigkeit, Tritt- und Biegefestigkeit etc.) im Ergebnis nicht schlechter als die eines vollständig aus Polyurethan bestehenden Belages.Due to the relatively rough surface of the particle board, the adhesive connection with the step to be repaired has become much more secure. Furthermore, the lower specific weight of the particle board compared to the polyurethane makes the covering significantly lighter, which of course also facilitates assembly work and reduces transport costs. It should also be emphasized that the costs for the production of the covering are significantly reduced, since approximately 2 kg of polyurethane are saved per covering for a step to be repaired and are replaced by the significantly cheaper pressboard. Despite this measure, the strength (also notched impact strength, impact and bending strength, etc.) is not inferior to that of a covering made entirely of polyurethane.

Aus der DE-PS 964 983 ist zwar eine Fußbodenplatte aus Holzfasern und aufgeklebtem Gummi- oder Kunstharzbelag bekannt. Dort geht es jedoch um die möglichst wasserdichte Ausbildung des gesamten Belages. Auch fehlt dieser Druckschrift jegliche Anregung, den dort gezeigten Belag in Verbindung mit Ausbesserungsarbeiten an Treppenstufen zu verwenden.From DE-PS 964 983 a floor plate made of wood fibers and glued rubber or synthetic resin covering is known. However, it is about making the entire covering as watertight as possible. This publication also lacks any suggestion to use the covering shown there in connection with repair work on stairs.

Im folgenden wird die Erfindung anhand von Ausführungsbeispielen im Zusammenhang mit der Zeichnung ausführlicher erläutert. Es ziegt:

  • Fig. 1 bis 3 je eine seitliche Schnittansicht eines Belages nach der Erfindung in verschiedenen Varianten;
  • Fig. 4 eine Seitenansicht eines Belages nach einer weiteren Variante der Erfindung.
The invention is explained in more detail below on the basis of exemplary embodiments in conjunction with the drawing. It moves:
  • Figures 1 to 3 each a side sectional view of a covering according to the invention in different variants.
  • Fig. 4 is a side view of a covering according to a further variant of the invention.

Die Fig. 1 bis 3 zeigen einen Ausschnitt einer zu sanierenden Treppe mit einer ausgetretenen Trittstufe 10, den beiden daran angrenzenden Stellstufen 11 und 12 und einer benachbarten weiteren Trittstufe 13. Die Trittstufe 10 ist mit einer Stoßkante über die Stellstufe 11 hinaus verlängert und steht somit geringfügig über. Es sei allerdings darauf hingewiesen, daß die Erfindung auch bei Treppen anwendbar ist, bei denen Tritt- und Stellstufe ohne einen solchen Vorsprung direkt ineinander übergehen.1 to 3 show a section of a staircase to be renovated with a step 10 which has emerged, the two adjoining steps 11 and 12 and an adjacent further step 13. The step 10 is extended with a butt edge beyond the step 11 and thus stands slightly above. However, it should be pointed out that the invention can also be used on stairs in which the step and adjusting step merge directly into one another without such a projection.

Auf die zu sanierenden Treppenstufen wird ein Belag 20 aufgebracht, der wie folgt aufgebaut ist:A covering 20 is applied to the stairs to be renovated, which is constructed as follows:

Grundsätzlich hat der Belag einen Trittstufenschenkel 21 und einen einstückig mit ihm verbundenen, senkrecht abstehenden Stellstufenschenkel 25, der parallel zur angrenzenden Stellstufe verläuft. Nacht der Erfindung hat zumindest der Trittstufenschenkel 21 an seiner Unterseite, d.h. an der zur Trittstufe 10 gegenüberliegenden Seite einen Einleger aus einer Preßspanplatte 24, die ein geringeres spezifisches Gewicht als der übrige Kunststoff des Belages 20 hat. Dieser Einleger wird bei der Herstellung des Belages in eine Gieß- oder Spritzform eingelegt und mit dem Kunststoff fest verbunden. Vorzugsweise ist die Dicke dieser Preßspanplatte 24 etwa gleich der Hälfte der Dicke des Trittstufenschenkels 21, so daß dieser zur Hälfte aus Kunststoff 23 und zur Hälfte aus dem leichteren Material der Preßspanplatte 24 besteht.Basically, the covering has a tread leg 21 and a vertically protruding adjusting leg 25 which is connected in one piece to it and runs parallel to the adjoining adjusting step. According to the invention, at least the tread leg 21 has on its underside, i.e. on the side opposite the step 10, an insert made of a particle board 24, which has a lower specific weight than the rest of the plastic of the covering 20. This insert is placed in a casting or injection mold during the manufacture of the covering and firmly connected to the plastic. Preferably, the thickness of this particle board 24 is approximately equal to half the thickness of the tread leg 21, so that it consists of half of plastic 23 and half of the lighter material of the particle board 24.

Der Einleger kann sich über die gesamte Breite des Belages erstrecken und - wie in den Ausführungsbeispielen der Fig. 1 bis 3 gezeigt - auch soweit nach hinten in Richtung zur angrenzenden Stellstufe 12, daß sie an der so definierten "hinteren" Stirnseite des Trittstufenschenkels 21 endet. Es ist allerdings auch möglich, rings um den Einleger einen Rand zu belassen, so daß seine Stirnseiten vom Kunststoff eingefaßt sind.The insert can extend over the entire width of the covering and - as shown in the exemplary embodiments of FIGS. 1 to 3 - also as far backwards in the direction of the adjoining setting step 12 that it ends at the "rear" end face of the step leg 21 defined in this way . However, it is also possible to leave an edge all around the insert so that its end faces are surrounded by plastic.

Die Verwendung der Preßspanplatte als Einlagematerial hat folgende Vorteile: Das Material hat im Vergleich zum Kunststoff ein deutlich geringeres spezifisches Gewicht, ist kostengünstig zu erwerben und hat eine ausreichende Festigkeit hinsichtlich Druck- und Biegekräften. Auch verbindet es sich aufgrund seiner Oberflächenstruktur gut mit gießbarem Kunststoff wie z.B. Polyurethan bzw. einem PU-Gießelastomer, so daß auch bei starker Beanspruchung der Treppe sich die einzelnen Schichten nicht voneinander lösen.The use of particle board as an insert material has the following advantages: The material has a significantly lower specific weight than plastic, is inexpensive to purchase and has sufficient strength with regard to compressive and bending forces. Due to its surface structure, it also combines well with castable plastic such as Polyurethane or a PU cast elastomer, so that the individual layers do not separate from one another even when the stairs are subjected to heavy loads.

Im Ausführungsbeispiel der Fig. 1 ist der senkrecht von dem Trittstufenschenkel 21 abstehende einstückig an diesem angeformte Schenkel als kurzer Stellstufenschenkel 25 ausgebildet, der die Vorderkante der zu sanierenden Trittstufe 10 überdeckt, jedoch die ihm unmittelbar benachbart liegende Stellstufe 11 im wesentlichen frei läßt. Wie aus Fig. 3 ersichtlich, kann die Stellstufe 11 verkleidet werden durch eine separate Blende 30, die von dem nach unten über die Unterkante der Trittstufe 10 herausragenden Teil des Stellstufenschenkels 25 gehalten wird.In the exemplary embodiment in FIG. 1, the leg protruding perpendicularly from the tread leg 21 is integrally formed on this leg as a short adjusting leg 25, which covers the front edge of the tread 10 to be renovated, but which immediately adjoins it beard lying control stage 11 leaves essentially free. As can be seen from FIG. 3, the setting step 11 can be covered by a separate cover 30, which is held by the part of the setting step leg 25 which projects downward beyond the lower edge of the step 10.

Im Ausführungsbeispiel der Fig. 2 ist der parallel zur Stellstufe 11 liegende vordere Stellstufenschenkel 25 des Belages 20 so lang, daß er unter Berücksichtigung des Belages der Trittstufe 13 die Stellstufe 11 vollständig abdeckt. Seine Länge entspricht also der der Stellstufe. Nach der in Fig. 2 dargestellten Variante der Erfindung hat auch der Stellstufenschenkel 25 einen Einleger 27 aus einer Preßspanplatte. Damit sit auch der Stellstufenschenkel 25 zweilagig ausgebildet, nämlich aus Kunststoff 26 und der Preßspanplatte 27.In the exemplary embodiment in FIG. 2, the front leg 25 of the covering 20 lying parallel to the setting step 11 is so long that it completely covers the setting step 11, taking into account the covering of the step 13. Its length therefore corresponds to that of the control stage. According to the variant of the invention shown in FIG. 2, the adjusting leg 25 also has an insert 27 made of a particle board. This also means that the actuator leg 25 is constructed in two layers, namely made of plastic 26 and the pressboard 27.

Wie noch aus Fig. 2 zu erkennen ist, kann der Trittstufenschenkel 21 über den senkrecht nach unten abstehenden Schenkel 25 verlängert sein zur Bildung einer Stoßkante 28. Eine solche Stoßkante kann natürlich auch bei den übrigen Varianten der Fig. 1, 3 und 4 vorgesehen sein.As can still be seen from FIG. 2, the tread leg 21 can be extended over the leg 25 projecting vertically downward to form a butt edge 28. Such an butt edge can of course also be provided in the other variants of FIGS. 1, 3 and 4 .

Fig. 4 zeigt eine Seitenansicht eines Belages nach einer weiteren Variante der Erfindung, bei der der Belag ein Z-förmiges Querschnittsprofil aufweist. Dort steht zusätzlich von der Oberseite des Trittstufenschenkels 21 ein weiterer Stellstufenschenkel 31 ab, dessen Länge der Tritthöhe der zu sanierenden Treppenstufe entspricht, während von der Unterseite des Trittstufenschenkels 21 der kürzere Stellstufenschenkel 25 absteht. Auch hier besitzt der weiter Stellstufenschenkel 31 ebenfalls eine Ausnehmung, die mit einem Material 32 gefüllt ist, das ein geringeres spezifisches Gewicht hat als die Kunststoffmasse.4 shows a side view of a covering according to a further variant of the invention, in which the covering has a Z-shaped cross-sectional profile. There also protrudes from the top of the tread leg 21 a further adjusting leg 31, the length of which corresponds to the step height of the step to be renovated, while the shorter adjusting leg 25 protrudes from the underside of the tread leg 21. Here, too, the further adjustment leg 31 also has a recess which is filled with a material 32 which has a lower specific weight than the plastic mass.

Bei allen Varianten der Erfindung können die Oberseite des Trittstufenschenkels 21 und die Vorderseite des Stellstufenschenkels eine Strukturierung aufweisen, die einer Holzmaserung entspricht. Die so strukturierten Oberflächen können mit einem Effektlack überzogen sein.In all variants of the invention, the top of the tread leg 21 and the front of the tread leg can have a structure that corresponds to a wood grain. The surfaces structured in this way can be coated with an effect lacquer.

Wie an sich bekannt, wird der Belag nach der Erfindung durch eine Füllkleber-Spachtelmasse 35 an den zu sanierenden Treppenstufen befestigt. Zumindest die gesamte Trittstufe 10 und bei der Variante der Fig. 3 auch die Stellstufen 11 und 12, wird mit dieser Masse 35 beschichtet, so daß einerseits eine vollflächige Klebeverbindung hergestellt wird und andererseits ausgetretene Vertiefungen der zu sanierenden Trittstufe 10 vollständig ausgefüllt sind.As is known per se, the covering according to the invention is attached to the stairs to be renovated by a filler adhesive filler 35. At least the entire step 10 and in the variant of FIG. 3 also the setting steps 11 and 12 are coated with this mass 35, so that on the one hand a full-surface adhesive connection is produced and on the other hand depressed depressions of the step 10 to be renovated are completely filled.

Obwohl nicht in den einzelnen Figuren dargestellt, kann der Belag nach der Erfindung im Bereich der Vorderkante des Trittstufenschenkels 21 eine Rutschhemmung haben, beispielsweise durch eine an sich bekannte Profilierung oder durch eine in einer Nut gehaltene Einlage aus rutschfestem Material, wie z.B. Gummi.Although not shown in the individual figures, the covering according to the invention can have a slip resistance in the region of the front edge of the tread leg 21, for example by a profile known per se or by an insert made of non-slip material, such as e.g. Rubber.
