Definitions

  • the invention relates to carpet tiles for the formation of a textile floor surface, the carpet tiles having a wear layer made of textile material on their upper side and a backing on their underside and a rectangular or square shape in which two side edges of the same length are parallel opposite each other.
  • Carpet tiles of this type have been known for a long time and are commercially available in a wide range of different colors and designs. The production of such carpet tiles has long been part of the state of the art. Accordingly, carpet tiles are punched or cut out of a carpet strip produced for this purpose, which results in side edges on the side edges of the carpet tiles.
  • the textile wear layer On the upper side of the carpet tiles produced in this way is the textile wear layer, which can be, for example, a pile layer produced using the weaving process or the tufting process, or a needle-punched fleece.
  • the carpet tiles are rectangular or square in shape.
  • a textile floor surface is generally understood here to mean a product that results when the carpet tiles are laid on a floor.
  • liquid for example water
  • reaches the floor surface from above can get down through the seam areas or seams between individual carpet tiles onto the subfloor, for example when cleaning the floor surface with a liquid or, if unintentionally, a larger one Amount of liquid gets onto the floor surface, for example in the event of water damage or if a bucket of water on the floor surface falls over.
  • the penetration of liquid through the seam areas is disadvantageous because the liquid then reaches the underside of the carpet tiles and can lead to the formation of mold there, for example.
  • the present invention is therefore based on the object of creating carpet tiles for the formation of a textile floor surface in which the aforementioned disadvantages of known carpet tiles are avoided and with which an overall liquid-tight floor surface can be produced, these carpet tiles being laid in a simple and quick manner .
  • a carrier plate is located under the backing of the carpet tiles, on the top of which a liquid-tight and double-sided adhesive film is glued, and the backing is glued to the adhesive film, whereby the shape and size of the carrier plate and the adhesive film and the shape and size of the associated carpet tile match, the carrier plate with the adhesive film is arranged offset in a diagonal direction with respect to the carpet tile, so that the carrier plate with the adhesive film protrudes on two adjacent side edges of the carpet tile and this overhang forms an edge area of the carrier plate or adhesive film that is not covered by the wear layer or the backing of the covering and is diagonally opposite the aforementioned side edges in the area of the two
  • the adjacent and also adjacent side edges of the carpet tile have an edge area of the back of the floor covering that corresponds to the above-mentioned overhang and is not covered by the carrier plate with the adhesive film, whereby when carpeting tiles designed in this way are placed next to one another, an overlapping and sticking of edge regions of
  • the backing of the covering is glued on only in a partial area of the adhesive film or carrier plate, namely the area of the carrier plate which is not covered by the wear layer or the covering backing to form the protrusion.
  • the carrier plate as well as the backing of the covering and the wear layer have the same shape and size, but not necessarily the same thickness or height.
  • the liquid-tight layer results from the placing of the individual carpet tiles next to one another, because then namely the carrier plates of adjacent carpet tiles also lie against one another.
  • the adhesive film which is attached to the upper side of each carrier plate facing the back of the covering forms a liquid-tight layer overall in the case of a floor surface made with carpet tiles of this type. Seen over the entire floor surface, this liquid-tight layer, which consists of the individual adhesive films of the carrier plates attached to the carpet tiles, extends.
  • the carrier plate with the adhesive film stuck to it is arranged offset in a diagonal direction relative to the backing of the covering and the wear layer on it, i.e. the actual carpet tile.
  • the set arrangement has the effect that the carpet tiles consisting of the backing of the floor covering and the wear layer cover the seams or seam edges that are present along their adjacent carrier plates (with the adhesive film on them).
  • This covering results from the fact that the protruding edge areas, i.e. an edge area of the backing of a carpet tile that is not covered by the carrier plate with the adhesive film, overlaps or covers an edge area of an adjacent carpet tile that is not covered by the backing with the wear layer.
  • This overlapping or covering means that liquid such as water, for example, that reaches the floor surface from above can pass through the seams or seam areas of the backing of the floor covering or wear layers of adjacent carpet tiles, but under the back of the flooring it can get through the Liquid-tight adhesive films located on the carrier plates is stopped. Because of the diagonally offset arrangement, the liquid passing through the seams of adjacent backing or wear layers does not directly hit the seams between adjacent carrier plates. This is due to the fact that the seams of adjacent backs of the covering or wear layers are also offset from the seams of adjacent carrier plates.
  • the arrangement of the liquid-tight adhesive films on the carrier plates and the offset arrangement of the backing of the covering (with the wear layer) and the carrier plates (with the adhesive film) mean that floor surfaces made with such carpet tiles are 100% liquid-tight.
  • the applicant has determined that this liquid-tightness is guaranteed by means of appropriate tests, using a recognized test method.
  • a reliably liquid-tight floor surface can be produced.
  • the laying takes place in an advantageous manner without additional materials or fasteners, that is, for example, no adhesives or the like and also not the "tile connectors" described above are required contaminated or damaged carpet tile is easily possible.
  • no special precautions are required on the subfloor for the laying of carpet tiles according to the invention.
  • the subfloor only has to be clean, even and smooth. If any old building materials on the subfloor or floor are load-bearing, firm and are otherwise free of complaints, they do not necessarily have to be removed in order to lay the carpet tiles according to the invention. However, it is advisable to remove all old building materials down to the screed surface, for example during renovation, and to provide a clean, even and smooth surface for laying the carpet tiles according to the invention. The latter is also important because the carpet tiles are not glued to the floor, but instead, according to the invention, are adhesively connected to one another in the protruding areas, that is to say the overhangs, by means of the adhesive film.
  • the carpet tiles according to the invention are not specified with regard to their size.
  • the carpet tiles can have a rectangular or square shape and can be produced in a wide variety of sizes.
  • the size of the protrusion or the width of the protruding edge area must be measured according to the size of the carpet tiles or the carrier plates attached underneath.
  • the side edges of which have a length of, for example, 50 cm, a value of 20 mm, for example comes into consideration as the dimension of the protrusion or the width of the protruding edge area. As a rule, these edge areas should be made wider for larger carpet tiles and, conversely, narrower for smaller-format tiles.
  • the dimension of the protrusion or the width of the protruding edge area can preferably be between 10 and 50 mm.
  • the adhesive connection that takes place there has a greater adhesive force, the larger the overhang or the wider the overhanging edge area, i.e. the larger the adhesive surface. If the overhang is made too wide or too large, the adhesive force is possibly too great to be able to easily remove a carpet tile from the textile floor surface if necessary.
  • the dimensioning of the protrusion or the width of the protruding edge area should therefore be a compromise between on the one hand sufficient strength of the adhesive connection and on the other hand an adhesive connection that is not too tight in order not to make it unnecessarily difficult to remove a carpet tile.
  • the carrier plate consists of a plastic, cardboard or cardboard material. These materials are inexpensive and at the same time very well suited to meet the requirements of such carpet tiles.
  • the thickness of the carrier plate is preferably between 0.1 and 1.0 mm. Dimensioning the thickness of the The carrier plate is important for the carpet tiles according to the invention insofar as the carrier plate should neither be too thick nor too thin.
  • a certain thickness of the carrier plate is advantageous because the carpet tile with the carrier plate is given a certain inherent weight, which is advantageous with regard to the lying properties of textile floor surfaces produced in this way.
  • a certain thickness of the carrier plate brings about a certain strength and stability of the carrier plate serving as a base.
  • the carrier plate should not be too thick, so that the carpet tile overall does not become too heavy and the carrier plate can also be cut well, which may be necessary when laying, for example, to make adjustments.
  • the selection of the material for the liquid-tight adhesive film is also important.
  • a plastic is proposed as a particularly advantageous material.
  • the adhesive film should moreover preferably have a thickness between 0.05 and 0.25 mm.
  • the carpet tile according to the invention it is provided that on the upward-facing side of the adhesive film on the surface of the protruding edge area there is a removable and non-self-adhesive protective film, when removed, the upward-facing side of the adhesive film is exposed and sticking to each other laid carpet tiles is made possible.
  • the aforementioned protective film is preferably made of paper that is coated on both sides with silicone. This protective film serves as a cover for the top or the upward-facing side of the adhesive film attached to a carrier plate and is only removed shortly before laying the carpet tile in order to expose the adhesive surface of the adhesive film.
  • the protective film protects this adhesive surface above all from soiling or from unintentional sticking of other objects.
  • the protective film thus has the same shape as the edge region of the carrier plate that is not covered by the backing of the covering (or the wear layer).
  • the protective film is therefore a practical means of protecting the carpet tile according to the invention before laying it and ensuring that the adhesive upper side of the adhesive film that is exposed and sticky after the protective film has been removed can develop an optimal adhesive force.
  • a carpet tile according to the invention with the carrier plate attached to it can be produced in the most varied of ways. One possibility is to first make a rectangular or square carrier plate made of a plastic material, for example by cutting a large plastic sheet accordingly, and to stick an adhesive film of the same shape and size to one of the two sides of this carrier plate.
  • This adhesive film can be a commercially available adhesive film that is covered on both sides with a removable and non-self-adhesive protective film.
  • one of the protective films which are present on both sides of the adhesive film and made, for example, of paper coated with silicone, is first removed.
  • the adhesive film is then glued to the carrier plate, the other protective film is still on the other side of the adhesive film.
  • the protective film must be removed from the adhesive film , namely in the area in which these two elements, i.e. the carrier plate and the carpet tile, are to be connected to one another by means of the adhesive film. This is the area which afterwards or in the finished state of the product does not form the protrusions or the uncovered edge areas of the carrier plate or the back of the covering.

  • the adhesive films 39 and 55 also abut one another so that they form a continuous, liquid-tight layer. So if a liquid, for example water, gets onto the adjacent carpet tiles 32 and 51 from above and this water should get through the seam formed by the side edges 35 and 56 between the backs of the covering 38 and 53, this water will consist of the liquid-tight layer from the adhesive films 39 and 55 stopped.
  • FIGS. 9 and 10 are also intended to show how the textile floor surface consisting of the two carpeted floor tiles 32 and 51 placed next to one another in FIGS. 9 and 10 is expanded or enlarged by applying further square carpet tiles 66, 67 and 68.
  • the carpet tiles 66-68 have the same training, shape and size or dimension as the carpet tiles 32 and 51, so that this need not be explained again here.
  • Fig. 11 first shows how the third carpet tile 66 to the carpet tiles 32 and 51 has been applied.
  • the carpet tile 66 also has a backing with a wear layer 69, specifically with the four side edges 70-73.
  • the Trä gerplatte 74 has the four side edges 75-78. As can be seen in Fig.
  • the carpet tile 66 is flush with the side edge 77 of its carrier plate 74 on the side edges 47 (the carpet tile 32) and 63 (the carpet tile 51), in such a way that the side edge 77 each with a half length on the side edges 47 and 63 respectively.
  • the carpet tile 66 is therefore not only or not completely applied to the carpet tile 32 (or to the carpet tile 51). Consequently, only half the length of the side edge 72 of the wear layer 69 rests against the side edge 37 (the carpet tile 32) or the side edge 59 (the carpet tile 51).
  • This arrangement improves the liquid-tightness of the entire textile floor surface consisting of the carpet tiles 32, 51 and 66, because the carrier plates 40, 54 and 74 do not lie against one another in a checkerboard manner.
  • the carrier plates 40, 54 and 74 are arranged offset from one another and therefore their side edges 45, 60 and 76 do not form a point of intersection through which liquid could otherwise possibly get down to the floor. This laying technique is therefore to be regarded as particularly advantageous.
  • FIG. 12 shows how a fourth carpet tile 67 and a fifth carpet tile 68 are now applied to the three carpet tiles 32, 51 and 66 shown in FIG. 11. How this is done in detail is readily apparent from the illustration in FIG. 12.
  • the carpet tile 67 is thus placed flush against the carpet tile 66 or against the carpet tile 51.
  • the carpet tile 68 is placed flush with the carpet tiles 51 and 67.
  • the entire textile floor surface can gradually be formed and finished by using appropriate carpet tiles, for example in a living room, which is then liquid-tight as a whole through the use of the adhesive films.
  • the adhesive connection of the individual carpet tiles 32, 51, 66, 67 and 68 also results in an overall closed floor area, whereby it is also possible to replace individual carpet tiles with a new carpet tile if necessary (for example in the event of non-removable contamination or damage) of the same type.

Abstract

L'invention concerne des dalles de moquette pour former une surface de sol textile, une plaque de support se trouvant respectivement sous l'arrière du revêtement des dalles de moquette, une feuille adhésive imperméable aux liquides et à adhérence double face étant collée sur la surface de la plaque de support qui est orientée vers l'arrière du revêtement. La juxtaposition de telles dalles de moquette permet de former sous l'arrière du revêtement une couche continue imperméable aux liquides. Il est ainsi possible de produire une surface de sol globalement imperméable aux liquides.
