Abstract
A floor panel is of synthetic material and forms a layer-shaped substrate with first and second pairs of opposite edges. The first pair of opposite edges has coupling parts forming a first mechanical locking system, which, in a coupled condition of two of such floor panels, effects a locking in the plane of the floor panels and perpendicular to the respective edges, and forms a second mechanical locking system, which, in a coupled condition of two of such floor panels, effects a locking transverse to the plane of the panels. The coupling parts on the first pair of opposite edges are realized substantially in the material of the floor panel itself. The floor panel is provided with an edge configuration on the second pair of edges allowing two of such floor panels to be positioned with their respective edge alongside each other and free from mechanical horizontally active locking systems.

BRIEF DESCRIPTION OF THE DRAWINGS
[0041] With the intention of better showing the characteristics of the invention, herein below, as an example without any limitative character, some preferred embodiments are described, with reference to the accompanying drawings, wherein:

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION
[0047] The figures are schematic representations which are self-evident. Herein, the figures, such as mentioned herein above, relate to five aspects, which also have been explained in the introduction. The general references P1 and P2 in the figures refer to the first pair of edges and second pair of edges, respectively. Reference A schematically represents an adhesive means or the like, whereas reference Z refers to locating edges.
[0048] The various cross-sectional views substantially have the purpose of visualizing the principles of the locking in certain directions or not locking in certain directions.
[0049] So, for example,
[0050] Herein below, the various aspects of the invention will be explained in greater detail.
[0051] The first aspect is explained herein below by means of
[0052] According to this first aspect, the invention relates to a floor panel 1 for forming a floor covering 2, wherein this floor panel 1 is realized substantially on the basis of synthetic material and preferably as a layer-shaped, either single-layer or multi-layer, substrate 3; wherein this floor panel 1 is rectangular, either oblong or square, and thus, as indicated in
[0053] Still according to the first aspect, the first pair of opposite edges 4-5, as in the examples of
[0054] It is noted that such coupling parts 8-9, which in coupled condition provide for a mechanical locking in horizontal as well as vertical direction, can be realized in different manners and are not limited to the embodiments of the
[0055] According to
[0056] It is noted that, in the case that, as aforementioned, the first pair of opposite edges is configured such that two of such panels 1 can be coupled to each other at these edges by means of a turning movement R, it is preferred that the second pair of edges is configured such that successively floor panels simply can be installed via a fold-down principle, such as further will become clear from the description of the second pair of edges. In the present application, by the “fold-down principle” must be understood that, when a newly to install floor panel is coupled to a preceding row of floor panels via said turning movement R, this movement also automatically has the final effect that the newly installed floor panel will arrive with its third or fourth edge in the intended end position in respect to the fourth or third edge of the preceding floor panel of the same row. According to the present patent application, the “fold-down principle” thus not necessarily implies that a vertical locking between the third and fourth edge of the adjacent floor panels must be achieved.
[0057]
[0058] In
[0059] According to a characteristic of the first aspect of the invention, such floor panel is characterized in that the floor panel, on the second pair of edges, is provided with an edge configuration which allows that two of such floor panels 1 can be positioned with their respective edges 6-7 alongside each other, wherein the configuration of the edges is free from mechanical horizontally active locking systems.
[0060] According to a particular possibility of the first aspect of the invention, the second pair of edges is also free from mechanical vertically active locking systems. The embodiments of

[0063] As represented in
[0064]
[0065] Preferably, however, use shall be made of flat flanges.
[0066] It is noted that the flanges 20-21 preferably have a thickness which is larger than ⅓ of the overall thickness of the floor panel.
[0067]
[0068] The embodiments of
[0069] As represented in
[0070] In general, the overlapping indeed shall be realized such that the floor panels in installed condition adjoin against each other in the proximity of their upper edges.

[0075] According to a not represented alternative, such lower flange also may be formed by a foil which is present on the lower side of the floor panel in an uninterrupted manner, for example, a backing layer which extends farther than the substrate itself.
[0076] As explained in the introduction, various types of adhesive can be applied for the herein above-mentioned adhesive means A; however, preferably use is made of a pressure-sensitive adhesive or glue.
[0077]
[0078]
[0079] In a particular deviating embodiment of the first aspect, this is characterized in that on the first pair of edges the aforementioned second locking system is absent and preferably the coupling parts are realized exclusively from a so-called drop-in system, whether or not combined with an adhesive means.

[0088] In the embodiment of
[0089] As becomes evident from the examples, it is generally preferred that the “velcro”-type fastening parts are active between overlapping flanges. Preferably, no other mechanical vertically active locking systems are applied therewith. Moreover, it is also preferred that no other horizontally active locking systems are applied therewith. For the first pair of edges, preferably coupling parts are applied of the type such as in
[0090] It is clear that according to the invention primarily decorative floor panels are concerned, thus, with a decorative upper side, for forming a floor covering on an existing supporting floor, and more particularly for forming a floating floor covering.
[0091] The invention is in particular intended for floor panels which substantially consist of synthetic material, or which comprise at least one or more basic layers on the basis of synthetic material, and more particularly with floor panels of the supple type.
[0092] Still more particularly, the invention shows its advantages best with vinyl panels, in particular so-called vinyl tiles, and in particular with panels of the so-called LVT type (“Luxury Vinyl Tile”) or VCT type (“Vinyl Composite Tile”, also called “Vinyl Composition Tile”). Of course, also comparable panels of other synthetic materials, such as PU, are applicable.
[0093] Such synthetic material floor panel, and in particular supple synthetic material floor panel, and more particularly such vinyl tile, preferably shows one of the following characteristics: [0094] the floor panel is substantially composed of one or more basic layers and at least a top layer, wherein the top layer as such may or may not be composed of a plurality of layers; [0095] herein, the top layer comprises at least a decorative layer, preferably in the form of a print, preferably provided on a foil or film; [0096] the top layer comprises at least a translucent or transparent wear layer; [0097] the floor panel is substantially composed of a thermoplastic material, preferably a soft thermoplastic material; [0098] the floor panel, or anyhow at least the one or more basic layers thereof, is/are substantially composed of polyvinyl chloride, more particularly of soft polyvinyl chloride, more particularly provided with plasticizers or the like; a composition “substantially” on the basis of PVC is to be interpreted broadly, as a large number of additives, for example, fillers, can be employed in PVC floors; [0099] the floor panel comprises at least one reinforcement layer, preferably formed of fibers, more particularly reinforcement fibers, such as glass fibers.
[0100] It is noted that “soft PVC” is a term expressing that this relates to supple PVC, in other words, PVC which is relatively smoothly bendable. The term soft PVC is widely known in the technique. Such soft PVC consists of PVC which has been softened, preferably by means of a plasticizer added during the production process. Depending on the added amount of plasticizer, of course different degrees of suppleness can be achieved.
[0101] By a plasticizer, any material must be understood which by being added results in a more supple PVC. Typical examples are phthalate plasticizers and isosorbide plasticizers.
[0102] By PVC which is softened, of course also PVC can be understood or a composition on the basis of PVC, which as such has the feature of being supple, for example, in that it is modified.
[0103] The same is valid for other “soft synthetic materials”, and the above is not limited to PVC.
[0104] As already stated herein above, the present invention shows its advantages best when it is applied with floor panels which substantially are manufactured of supple or soft synthetic material, or in other words with supple panels.
[0105] By supple floor panels, floor panels are intended, which panels, when they, in the case of a rectangular panel, for example, with a width of less than 50 centimeters, are clamped on one of the two short sides of the panel and herein protrude over a length of 100 centimeters and are not supported, will bend under the influence of their own weight, wherein this bending at the height of the free extremity in respect to the clamped extremity is minimum 10 centimeters. For this bending, a bending time of 10 seconds is taken into account, and wherein the panel starts from a flat horizontal position.
[0106] The present invention is in no way limited to the embodiments described by way of example and represented in the figures; on the contrary, the floor panels of the aforementioned aspects can be realized according to various variants, without leaving the scope of the invention.
[0107] So, the invention can also be applied, for example, with synthetic material-based floor panels which have a composed substrate, which panels also can be called hybrid floor panels. More particularly, this herein relates to a floor panel which consists at least of two substrate layers, each of a well-defined thickness, namely a first synthetic material-based substrate layer and a second substrate layer, situated there above, preferably directly there above, which second substrate layer has a thickness of at least 0.5 mm, preferably at least 1 mm; wherein this composed substrate, the floor panel concerned, respectively, also shows one of the following characteristics or any combination of these characteristics: [0108] the density of the first substrate layer differs from the density of the second substrate layer, and preferably the second substrate layer has a higher density than the first substrate layer; [0109] the first substrate layer is foamed, and preferably is of the closed cell type and still more preferably of the so-called hard foam type, and preferably the second substrate layer is not foamed or is less foamed than the first substrate layer; [0110] the first substrate layer is extruded in plate shape or is formed to a plate by means of a strewing process and consolidation of the strewn material; [0111] the second substrate layer consists of an extruded layer or of a layer which is formed by means of a strewing process and consolidation of the strewn material; [0112] the two substrate layers are glued to each other or, alternatively, are consolidated in the same production process, this latter, for example, by mutual direct adhesion among the materials of the substrates, or, for example, also by forming them of one composed mass with at least two layers;
[0113] In preferred embodiments of such floor panel with a composed substrate, this further may have one or more of the following characteristics, wherein all not contradictory combinations of characteristics are possible: [0114] that the aforementioned first substrate layer comprises at least a thermoplastic material; [0115] that the aforementioned first substrate layer is realized at least on the basis of polyvinyl chloride, polyethylene, polyurethane, polypropylene or PIR, or a combination of the preceding; [0116] that the aforementioned first substrate layer is a filled synthetic material composite, wherein this filling preferably consists at least of one or of a combination of the following materials: bamboo, cork and/or wood, and more particularly one or a combination of the aforementioned materials in the form of chips and/or fibers and/or dust or powder, such as sawdust; [0117] that the aforementioned first substrate layer is foamed; [0118] that the aforementioned first substrate layer is of the closed cell-type; [0119] that the aforementioned first substrate layer comprises one or more plasticizers; [0120] that the aforementioned first substrate layer comprises fillers, such as chalk and/or limestone and/or talc; [0121] that the aforementioned first substrate layer is provided with at least one reinforcement layer, preferably of glass fiber or the like; [0122] that the aforementioned first substrate layer has a thickness of at least 3 mm, preferably at least 4 mm, and still more preferably at least 5 mm; [0123] that the aforementioned first and/or second substrate layer is realized water-resistant; that the aforementioned second substrate layer is based on synthetic material; [0124] that the aforementioned second substrate layer comprises at least a thermoplastic material, which preferably is of the soft type; [0125] that the aforementioned second substrate layer is realized at least on the basis of vinyl, such as polyvinyl chloride, more particularly soft polyvinyl chloride, polyethylene, more particularly soft polyethylene, polyurethane, polypropylene, PIR or a combination of the preceding; [0126] that the aforementioned second substrate layer substantially consists of one or a combination of the following materials: wood veneer, rubber, linoleum, a paper-based or foil-based laminate sheet, or alternatively any material, more particularly cork, bamboo or wood veneer, which is encased by vinyl or resin; [0127] that the aforementioned second substrate layer comprises one or more plasticizers; that the aforementioned second substrate layer comprises fillers, such as chalk and/or limestone; [0128] that the aforementioned second substrate layer is provided with at least one reinforcement layer, preferably of glass fiber or the like; [0129] that the floor panel comprises a backing layer, which preferably is situated directly underneath the first substrate layer, which backing layer, for example, is realized on the basis of one or more of the following materials: cork, rubber and/or a soft foamed layer; [0130] that the floor panel comprises a top layer, whether or not consisting of a plurality of layers, which preferably is situated directly above the second substrate layer, and/or that the second substrate layer is provided with a backing layer on the lower side of this second substrate layer; [0131] that the aforementioned top layer comprises at least a decorative layer, preferably in the form of a print, preferably provided on a foil or film; [0132] that the aforementioned top layer comprises at least a translucent or transparent wear layer and/or is provided with hard particles in order to increase the wear resistance, such as corundum; [0133] that the floor panel has an overall thickness which is smaller than 10 mm, still better in the order of magnitude of 8 mm, or possibly thinner; [0134] that the aforementioned first substrate layer is foamed gradually, wherein the degree of foaming increases in downward or in upward direction.
