Definitions
- the present invention relates to seamlessly laid coverings of leather panels on the floor, wall and / or ceiling surfaces of an interior or a covering for stairs with the features of the preamble of claim 1, and a method for producing leather coverings with the features of the preamble of claim. 8
- a method of making a leather tile cladding is known.
- the leather tiles are each pressed with the back to form a joint gap on the floor and / or wall surface.
- the joint gap can be created, for example, by using a spacer such as a simple strip.
- the bonded leather tiles are then left alone for about 80 hours so that the leather tiles can acclimatize, ie they release excess moisture.
- the joint spaces are filled flush with a plastic-based filler.
- the filler is left to dry for about 8 hours, thereby shrinking. When shrinking creates a small groove on the outside of the joint. Thereafter, the grooves formed by the shrinkage are filled flush with the putty at least once more on the joint gaps.
- the putty is for drying about 8 hours at rest During this interim period, a little further shrinkage occurs.
- the protective layer on the top of the leather tiles is removed dry with a felt, which also eliminates the possible impurities thereon, and then the top of the leather tiles is polished dry by rubbing with a lambskin.
- the joint interspaces are filled flush with putty three times in compliance with the drying break. It is not always desirable for aesthetic reasons, that joint gaps are visible in the covering.
- that is from the DE-19634928 known method for filling the joints and the subsequent cleaning of the leather tiles extremely time consuming.
- the coverings, whose base material compared to other materials are already relatively expensive, are priced even more unattractive.
- the substrate must be pretreated in a first step.
- the edge zones of the surface to be covered are ground, for example with a slide mill, and then the substrate is primed with a fiber roller.
- a good leveling is done with a common filler once.
- the resulting underlay floor is ground, for example, with a 60 grit.
- the resulting smooth, even and absorbent substrate for receiving the adhesive can either be stuck directly to the leather panels, or various substructures can be applied. Cork or other known insulation underlays can be used for additional impact noise and / or thermal insulation.
- the to be laid leather panels come, as a floor is occupied, preferably of resilient animal skins such as beef, horse, buffalo or the like.
- the plates can be produced in a wide variety of shapes, colors and thicknesses. Vegetable is preferably vegetable, vegetable chromium or only chromium, but it can also be used any other tanned leather.
- the plates to be laid are preferably punched out in predetermined shapes. The size of the plates is limited by the size of the animal skins in a natural way. The natural material leather can be easily and precisely cut during laying as needed. Even complicated edges or corners can be laid with standard panels. Since the plates are relatively flexible, for example, stairs or other paragraphs or door sills can be occupied. When laying the prefabricated leather panels are glued with a low-dispersion dispersion adhesive over the entire surface of the substrate and pressed with a metal roller. The base is made with strips of leather in the desired width. These strips can be pure leather strips or leather-covered or occupied wooden strips.
- the adhesive After the adhesive has hardened sufficiently, it is sanded for the first time diagonally in the room with a 40 or 50 grit. The first cut is then sanded a second time with a 60 or 80 grit. A marginal cut with a 60 grit is followed by a marginal cut with a 100 to 120 grit. Then the corners are ground and finally a final polishing with a special plate, for example a five-disc plate, is carried out. After grinding, as shown in FIG. 3b, a smooth, stepless transition is created between the plates placed on the joint. There are no longer any supernatants that could be aesthetically disturbing or could lead to lateral detachment of the plate edges.
- the panels made of natural leather can not be cut or punched with 100% straight edges, small gaps between individual panels may occur during laying. These may be filled after the first and / or second sanding with a mixture of sanding dust and an alcohol-based binder which gives a cementitious paste.
- pseudo-joints can be produced by laying plates with a broken or chamfered upper edge 18, as shown in FIG.
- a pseudo joint 20 can be produced, as shown in FIG. 4b.
- a joint 20 is visible, although the floor is laid without joints, i. the individual plates 10 are in direct contact with each other via their side surfaces 12.
- the surface produced in this way can be treated according to the customer's wishes and purpose become. Without aftertreatment, the leather retains its raw, natural character particularly well. It can also be sealed, waxed or oiled. When sealing is primed in a first step with an alcohol-based primer and then sealed with water-based paint. With a 120 to 150 mesh is ground, sealed a second time and finally polished. As an alternative to sealing, it is also possible to wax or oil it with known means and then to polish it.
- the inventive leather floor allows completely new design possibilities.
- the leather panels can preferably be provided with patches before installation by baking or punching. By the subsequent grinding any disturbing elevations, which are caused by the baking or punching, completely removed.
- the ornament remains easily visible and may even be particularly highlighted by filling with a different color grinding dust-binder mixture.
- individual sheets of a non-leather material for example of a parquet wood, can be laid seamlessly between the leather panels. Grinding and subsequent surface treatment are not significantly different from the methods described above.
- the inventive leather cover Since the inventive leather cover is laid without joints and has a closed surface, it is extremely easy to maintain and clean. If the coating has become unattractive after prolonged mechanical stress or permanent contamination, it can be reground one or more times, depending on the thickness of the plates. the life of the coating according to the invention is thereby extended by decades.

Abstract
Description
Die vorliegende Erfindung betrifft fugenlos verlegte Beläge aus Lederplatten an Boden, Wand- und/oder Deckenflächen eines Innenraums oder eines Belages für Treppen mit den Merkmalen des Oberbegriffes des Patentanspruches 1, sowie ein Verfahren zum Herstellen von Lederbelägen mit den Merkmalen des Oberbegriffes des Patentanspruches 8.The present invention relates to seamlessly laid coverings of leather panels on the floor, wall and / or ceiling surfaces of an interior or a covering for stairs with the features of the preamble of
Böden, Treppenstufen oder Wandverkleidungen aus Leder sind zwar noch recht ungewöhnlich, weisen aber verschiedene Vorzüge auf. Laufflächen aus Leder sind erstaunlich belastbar, wasser- und schmutzabweisend, leicht zu Reinigen und Auszubessern. Das Naturmaterial Leder ist äusserst angenehm bei direktem Kontakt, so dass zum Beispiel ein Lederboden geradezu zum Barfusslaufen einlädt.Leather floors, steps or wall coverings are still quite unusual, but have different benefits. Leather treads are amazingly durable, water and dirt repellent, easy to clean and repair. The natural material leather is extremely pleasant in direct contact, so that, for example, a leather floor invites almost to barefoot running.

Es ist daher die Aufgabe der Erfindung, einen Belages aus Lederfliesen an Boden, Wand- und/oder Deckenflächen eines Innenraums oder einen Belag für Treppen und/oder Handläufe von Treppen zur Verfügung zu stellen, der die oben genannten Nachteile der bekannten Beläge nicht aufweist. Es ist zudem die Aufgabe der Erfindung ein Verfahren zur Herstellung eines solchen Belages zur Verfügung zu stellen.It is therefore the object of the invention to provide a covering made of leather tiles on the floor, wall and / or ceiling surfaces of an interior or a covering for stairs and / or handrails of stairs, which does not have the above-mentioned disadvantages of the known coverings. It is also the object of the invention to provide a method for producing such a covering.

In der Figur 1 ist ein Lederboden wie er aus dem Stand der Technik bekannt ist gezeigt. Die einzelnen Lederplatten P sind durch verfugte Zwischenräume F voneinander getrennt. Der in der Figur 2 gezeigte Lederboden gemäss einer Ausführungsform der vorliegenden Erfindung ist dagegen fugenlos verlegt. Im folgenden sollen kurz die wesentlichen Schritte beim Verlegen des erfindungsgemässen Belages anhand eines zu verlegenden Bodenbelages beschrieben werden.In the figure 1, a leather bottom as it is known from the prior art is shown. The individual leather panels P are separated by grouted gaps F from each other. The leather bottom shown in Figure 2 according to an embodiment of the present invention, however, is laid without joints. In the following, the essential steps in laying the covering according to the invention on the basis of a floor covering to be laid are briefly described.
Ueblicherweise muss in einem ersten Schritt der Untergrund vorbehandelt werden. Die Randzonen der zu belegenden Fläche werden zum Beispiel mit einer Dia-fräse geschliffen und anschliessend wird der Untergrund mit einer Faserwalze grundiert. Um die Poren zu verschliessen und Unebenheiten auszugleichen wird mit einer gebräuchlichen Spachtelmasse einmal gut gespachtelt. Der so entstandene Unterlagsboden wird zum Beispiel mit einer 60er Körnung geschliffen.
Der auf diese Weise entstandene glatte, ebene und saugfähige Untergrund zur Aufnahme des Klebers kann entweder direkt mit den Lederplatten beklebt werden, oder es können diverse Unterkonstruktionen aufgebracht werden.
Kork- oder andere bekannte Dämmunterlagen können zur zusätzlichen Trittschall- und oder Wärmedämmung verwendet werden.
Die zu verlegenden Lederplatten stammen, da ja ein Boden belegt wird, vorzugsweise von belastbaren Tierhäuten wie zum Beispiel Rind, Pferd, Büffel oder ähnlichen. Die Platten können in verschiedensten Formen, Farben und Stärken hergestellt werden. Gegerbt wird vorzugsweise vegetabil, vegetabil Chrom oder nur Chrom, es kann aber auch jedes andere gegerbte Leder verwendet werden. Die zu verlegenden Platten werden vorzugsweise in vorgegebenen Formen ausgestanzt. Die Grösse der Platten ist durch die Grösse der Tierhäute in natürlicher Weise begrenzt. Das Naturmaterial Leder lässt sich bei Bedarf während des Verlegens problemlos und sehr exakt zuschneiden. Auch komplizierte Kanten oder Eckverläufe können so mit Standardplatten verlegt werden. Da die Platten vergleichsweise flexibel sind, können zum Beispiel auch Treppenstufen oder andere Absätze oder Türschwellen belegt werden.
Beim Verlegen werden die vorgefertigten Lederplatten mit einem wasserarmen Dispersionskleber vollflächig mit dem Untergrund verleimt und mit einer Metallwalze angepresst. Der Sockelabschluss wird mit Leisten aus Leder in gewünschter Breite erstellt. Diese Leisten können reine Lederstreifen oder mit Leder überzogene oder belegte Holzleisten sein.Usually, the substrate must be pretreated in a first step. The edge zones of the surface to be covered are ground, for example with a slide mill, and then the substrate is primed with a fiber roller. To close the pores and to compensate for bumps, a good leveling is done with a common filler once. The resulting underlay floor is ground, for example, with a 60 grit.
The resulting smooth, even and absorbent substrate for receiving the adhesive can either be stuck directly to the leather panels, or various substructures can be applied.
Cork or other known insulation underlays can be used for additional impact noise and / or thermal insulation.
The to be laid leather panels come, as a floor is occupied, preferably of resilient animal skins such as beef, horse, buffalo or the like. The plates can be produced in a wide variety of shapes, colors and thicknesses. Vegetable is preferably vegetable, vegetable chromium or only chromium, but it can also be used any other tanned leather. The plates to be laid are preferably punched out in predetermined shapes. The size of the plates is limited by the size of the animal skins in a natural way. The natural material leather can be easily and precisely cut during laying as needed. Even complicated edges or corners can be laid with standard panels. Since the plates are relatively flexible, for example, stairs or other paragraphs or door sills can be occupied.
When laying the prefabricated leather panels are glued with a low-dispersion dispersion adhesive over the entire surface of the substrate and pressed with a metal roller. The base is made with strips of leather in the desired width. These strips can be pure leather strips or leather-covered or occupied wooden strips.
Nachdem der Kleber ausreichend abgebunden hat wird mit einer 40er oder 50 er Körnung diagonal im Raum ein erstes Mal geschliffen. Quer zum ersten Schliff wird anschliessend mit einer 60er oder 80er Körnung ein zweites Mal geschliffen.
Einem Randschliff mit einer 60er Körnung schliesst sich ein Randschliff mit einer 100er bis 120er Körnung an. Danach werden die Ecken geschliffen und abschliessend wird ein Endschliff mit einem Spezialteller, zum Beispiel einem Fünfscheibenteller, durchgeführt.
Nach dem Schleifen ist wie aus der Figur 3b hervorgeht ein planer stufenloser Übergang zwischen den auf Stoss verlegten Platten erzeugt. Es sind keine Überstände mehr vorhanden, die ästhetisch störend sein könnten oder durch seitliche Stossbelastung zum Ablösen der Plattenkanten führen könnten.After the adhesive has hardened sufficiently, it is sanded for the first time diagonally in the room with a 40 or 50 grit. The first cut is then sanded a second time with a 60 or 80 grit.
A marginal cut with a 60 grit is followed by a marginal cut with a 100 to 120 grit. Then the corners are ground and finally a final polishing with a special plate, for example a five-disc plate, is carried out.
After grinding, as shown in FIG. 3b, a smooth, stepless transition is created between the plates placed on the joint. There are no longer any supernatants that could be aesthetically disturbing or could lead to lateral detachment of the plate edges.
Da die Platten aus dem Naturmaterial Leder nicht mit 100% geraden Kanten geschnitten oder ausgestanzt werden können, kann es beim Verlegen zu kleinen Spalten zwischen einzelnen Platten kommen. Diese können nach dem ersten und/oder zweiten Schleifgang mit einer Mischung aus Schleifstaub und einem Bindemittel auf Alkoholbasis, welche eine zementöse Paste ergeben, verfüllt werden.Since the panels made of natural leather can not be cut or punched with 100% straight edges, small gaps between individual panels may occur during laying. These may be filled after the first and / or second sanding with a mixture of sanding dust and an alcohol-based binder which gives a cementitious paste.
Ist es aus optischen Gründen gewünscht, so können sogenannte Pseudofugen erzeugt werden, indem , wie in der Figur 4 dargestellt, Platten mit einer gebrochenen oder gefasten oberen Kante 18 verlegt werden. Bei dieser Ausführungsform der Erfindung kann durch Beimengen von Farbpigmenten zum Schleifstaub-Bindemittelgemisch eine Pseudofuge 20 erzeugt werden, wie sie in der Figur 4b dargestellt ist. An der Oberfläche 11 des Lederbodens 1 ist eine Fuge 20 sichtbar, obwohl der Boden Fugenlos verlegt ist, d.h. die einzelnen Platten 10 über ihre Seitenflächen 12 in direktem Kontakt zueinander liegen.If it is desired for optical reasons, so-called pseudo-joints can be produced by laying plates with a broken or chamfered
Nach dem Verlegen und Schleifen kann die so erzeugte Oberfläche je nach Kundenwunsch und Einsatzzweck noch nachbehandelt werden. Ohne Nachbehandlung bleibt dem Leder sein roher, natürlicher Charakter besonders gut erhalten. Es kann aber auch versiegelt, gewachst oder geölt werden. Beim Versiegeln wird in einem ersten Schritt mit einer Grundierung auf Alkoholbasis grundiert und anschliessend mit Wasserlack versiegelt. Mit einem 120er bis 150er Netz wird zwischengeschliffen, ein zweites Mal versiegelt und abschliessend poliert.
Alternativ zum Versiegeln kann auch mit bekannten Mitteln gewachst oder geölt und anschliessend poliert werden.After laying and sanding, the surface produced in this way can be treated according to the customer's wishes and purpose become. Without aftertreatment, the leather retains its raw, natural character particularly well. It can also be sealed, waxed or oiled. When sealing is primed in a first step with an alcohol-based primer and then sealed with water-based paint. With a 120 to 150 mesh is ground, sealed a second time and finally polished.
As an alternative to sealing, it is also possible to wax or oil it with known means and then to polish it.
Der erfindungsgemässe Lederboden lässt völlig neue gestalterische Möglichkeiten zu. Die Lederplatten können vorzugsweise vor dem Verlegen durch Einbrennen oder Einstanzen mit Ornamenten versehen werden. Durch das anschliessende Schleifen werden allfällige störende Erhebungen, welche durch das Einbrennen oder -stanzen entstanden sind, vollständig entfernt. Das Ornament bleibt gut sichtbar und kann eventuell sogar durch Verfüllen mit einem farblich unterschiedlichen Schleifstaub-Bindemittelgemisch besonders hervorgehoben werden.The inventive leather floor allows completely new design possibilities. The leather panels can preferably be provided with patches before installation by baking or punching. By the subsequent grinding any disturbing elevations, which are caused by the baking or punching, completely removed. The ornament remains easily visible and may even be particularly highlighted by filling with a different color grinding dust-binder mixture.
Falls dies gewünscht ist, so können auch einzelne Platten aus einem Nicht-Ledermaterial, zum Beispiel aus einem Parkettholz, fugenlos zwischen die Lederplatten verlegt werden. Schleifen und anschliessende Oberflächenbehandlung unterscheiden sich nicht wesentlich von den oben beschriebenen Verfahren.If so desired, individual sheets of a non-leather material, for example of a parquet wood, can be laid seamlessly between the leather panels. Grinding and subsequent surface treatment are not significantly different from the methods described above.
Da der erfindungsgemässe Lederbelag fugenlos verlegt ist und eine geschlossene Oberfläche aufweist, ist er äusserst gut zu pflegen und zu reinigen. Sollte der Belag nach längerer mechanischer Beanspruchung oder bei bleibender Verschmutzung unattraktiv geworden sein, so kann er, je nach Stärke der Platten, ein oder mehrmals nachgeschliffen werden. die Lebensdauer des erfindungsgemässen Belages wird dadurch um Jahrzehnte verlängert.Since the inventive leather cover is laid without joints and has a closed surface, it is extremely easy to maintain and clean. If the coating has become unattractive after prolonged mechanical stress or permanent contamination, it can be reground one or more times, depending on the thickness of the plates. the life of the coating according to the invention is thereby extended by decades.
