    Set of floor panels and method for installing this set of floor panels.
    The present invention relates to a set of floor panels suitable for forming a floor covering, as well as a method for installing this set of floor panels.
    In particular, the invention relates to a set of floor panels that is suitable for forming a floor covering in a herringbone pattern.
    The floor panels are elongated rectangular and therefore have a few long edges and a few short edges. Both the long and the short edges are equipped with mechanical coupling parts that allow the floor panels to be connected to each other.
    Moreover, the set consists of at least two types of floor panels, wherein the coupling parts of one type of floor panels are mirrored on one pair of edges relative to the coupling parts of the other type of floor panels on that same pair. In better terms, it concerns the location of these coupling parts that is mirrored.
    Such a set of floor panels is known per se from, among others, the documents WO 2004/063491 A1 and WO 2005/054599 A1. WO 2004/063491 A1 is primarily focused on the use of coupling parts on the pair of short edges that are of the same type as the coupling parts on the pair of long edges. For example, coupling parts are applied to both the long and short edges which can be joined together via a turning and / or sliding movement. A disadvantage of this is that the installation of the floor panels in herringbone pattern is not always smooth.
    However, it is also stated in WO 2004/063491 A1 that coupling parts with a different configuration can be applied to the pair of short edges than the coupling parts to the pair of long edges. For example, coupling parts can be applied to the pair of short edges which can be inserted into each other via a downward movement, while coupling parts can be applied to the pair of long edges which fit into each other via a turning movement. In this case, however, it is not at all clear from WO 2004/063491 how the floor panels should then be installed in a herringbone pattern. WO 2005/054599 Although it does provide a way to install floor panels which are provided at the pair of short edges with coupling parts that can be joined together via a downward movement in herringbone pattern. The manner described therein allows a floor panel to be coupled in a single rotational movement both to the long and to the short edge with adjacent already installed floor panels with a herringbone pattern as a result. The single rolling movement is also referred to in the art as the folddown movement. However, the disclosed floor covering has the disadvantage that there is a substantial risk of height differences occurring between the mutually coupled floor panels. These height differences are undesirable since they are not visually attractive in the first place. In addition, they also ensure, for example, that the upper edges of the floor panels show wear more quickly where these height differences are present. These upper edges are then after all exposed to external influences. The described floor covering still has the disadvantage that with dimensional changes in the floor panels there is a significant risk of cracking or cracking or even a risk of projecting floor panels.
    Figure 6 of WO 2005/054599 A1 proposes a locking system that can be applied to the short edges of the floor panels. This locking system uses a separate insert. However, it is not at all clear from WO 2005/054599 how floor panels with such a locking system should then be installed in a herringbone pattern.
    The present invention aims in the first place at an alternative set of floor panels that is suitable for forming a floor covering in a herringbone pattern. In particular, it is an object of the invention to provide floor panels which, on the one hand, can be laid smoothly in a herringbone pattern and, on the other hand, can be firmly connected to each other such that the risk of height difference, slit or cracking between the mutually coupled floor panels can be minimized.
    To this end the invention relates to a set of floor panels which is suitable for forming a floor covering in herringbone pattern, wherein these floor panels are elongated rectangular and thus have a pair of long edges and a pair of short edges; wherein both the long and the short edges are provided with mechanical coupling parts that allow the floor panels to be connected to each other; wherein one long edge is provided with a male coupling part and the other long edge is provided with a female coupling part; wherein one short edge is provided with a male coupling part and the other short edge is provided with a female coupling part; wherein the male coupling part on the long edge can be inserted into the female coupling part on the long edge by means of a turning movement; wherein the male coupling part on the long edge can also be added to the short edge by means of a turning movement in the female coupling part; and wherein the male coupling part on the short edge can be inserted into the female coupling part on the long edge in one and the same turning movement used to add the male coupling part on the long edge in the female coupling part on the long or short edge; characterized in that the male coupling part on the short edge and the female coupling part on the long edge effect both a locking in the horizontal direction and a locking in the vertical direction in a coupled state thereof.
    The invention provides on the one hand the advantage that a floor covering in herringbone pattern can be obtained quickly. After all, the configuration of the floor panels makes it possible to connect these floor panels by means of the aforementioned fold-down movement and to lay them in a herringbone pattern. A floor panel from the set can be coupled at the same time with the long and short edge to adjacent and already installed floor panels from the set. The floor panel is then preferably coupled with the long and short edge to at least the long edges of the adjacent and already installed floor panels in order to obtain a herringbone pattern. On the other hand, in the obtained floor covering, the risk of height difference, crack or crack formation between the mutually coupled floor panels is minimized. After all, good locking is not only present between the mutually coupled long edges, but a strong locking can also be provided between the mutually coupled short and long edges.
    In a practical embodiment, the male coupling part on the short edge comprises a first locking element which, in a coupled state of this male coupling part and the female coupling part on the long edge, cooperates with a first locking element of this female coupling part to effect the aforementioned locking in the vertical direction .
    Where the first locking elements work together, a tangent line is preferably defined which runs upwards in the direction away from the respective female coupling part. This tangent line is therefore preferably oriented obliquely. The advantage of such cooperation is that, even with slight profile deviations due to tolerances that occur during the manufacture of the locking elements, it can still effect the vertical locking. In other words, it allows for these tolerances to be absorbed. Preferably, the aforementioned tangent line makes an angle with the horizontal that is less than or equal to 45 degrees.
    The first locking element of the male coupling part can be made of the material of the floor panel and in particular in one part therewith. This can be achieved, for example, by manufacturing this locking element with one or more cutting tools or cutting tools from the material of the floor panel.
    More preferably, however, the first locking element of the male coupling part is designed as a separate insert.
    The insert can be arranged in a recess in the male coupling part on the short edge. Preferably, the insert is then clamped in the recess by dimensioning this insert, for example, relative to the recess. In a particularly preferred embodiment the recess is arranged in a distal side or edge of the relevant male coupling part.
    The use of the insert provides the advantage that its properties do not depend on the material of the floor panel. The insert can be configured in such a way that it allows both a smooth installation and a good vertical locking, regardless of the material properties of the actual floor panel. The material of the insert preferably relates to plastic material. Examples of plastic material that can be used for this purpose are polyvinyl chloride, polypropylene, polyethylene or polyurethane. Furthermore, the material of the insert may further comprise fibers to increase its strength. For example, mineral fibers such as glass fibers can be used for this. The insert can be made from one and the same material, but this need not necessarily be the case. For example, the insert can be made up of several materials which, for example, exhibit different flexibility. Depending on the function of the specific part of the insert, it can then be made of a more or less flexible material. A technique that can be used to manufacture the insert from multiple materials is co-extrusion.
    It is noted that such an insert is known per se from among others the following documents: WO 2005/054599 A1, WO 2008/068245 A1, WO 2011/127981 A1 and WO 2013/118030 A2. The inserts described in these documents can be used in the present invention. More generally, any insert suitable for use with a folddown type floor panel can be used in the present invention.
    The insert preferably comprises a locking part which, when performing the coupling movement, ends up in a locking position by performing a lateral movement. This lateral movement may for example relate to a linear movement or a rotational or rotational movement. The insert or at least at least a part thereof is elastically deformable and / or displaceable to allow the aforementioned lateral movement.
    The lateral movement can be single or double. In the single movement, the locking part is brought directly from an initial position to a locking position during the coupling movement, and this preferably according to a movement in only one direction. In the case of the dual movement, the locking part is brought indirectly from an initial position to the locking position during the coupling movement and this, for example, by first moving the locking part in one direction to an intermediate position and then bringing it in the opposite direction from the intermediate position to the locking position. .
    The principle of the one-way lateral movement is known per se from, among others, the document WO 2011/127981 A1, while the principle of the two-way lateral movement is known per se from, among others, the documents WO 2005/054599 A1 and WO 2013/118030 A2 .
    It is further noted that the male coupling part on the short edge can be provided with a plurality of locking elements which, in a coupled condition, with the female coupling part on the long edge, respectively cooperate with a plurality of locking elements of the respective female coupling part. The cooperation of these multiple locking elements then brings about the vertical locking. The use of several locking elements has the advantage that a very strong vertical locking can be provided. Moreover, the reliability of the locking can also be increased: if one pair of the locking elements fails, there is at least another pair to compensate for this failure.
    In the case that the male coupling part is provided on the short edge with a plurality of locking elements which are responsible for locking in the vertical direction, they are preferably all made of the material of the floor panel and in particular in one part therewith.
    In a practical embodiment the male coupling part on the short edge comprises a second locking element which, in a coupled condition of this male coupling part with the female coupling part on the long edge, cooperates with a second locking element of the respective female coupling part in order to release said locking in the horizontal direction. bring about.
    Most preferably, the second locking element of the male coupling part on the short edge is made of the material of the floor panel and in particular in one part therewith. This can be achieved, for example, by manufacturing this locking element with one or more cutting tools or milling tools from the material of the floor panel.
    Where the second locking elements work together, they preferably define a tangent that runs upwardly in the direction away from the respective female coupling part. This tangent line therefore preferably runs obliquely. Such a configuration increases the smoothness of joining the respective coupling parts together. Preferably, the aforementioned tangent line makes an angle with the vertical that is less than 45 degrees and more preferably less than or equal to 30 degrees. Such an angle offers an excellent compromise between on the one hand the smoothness of the installation and on the other hand the strength of the horizontal locking.
    A particularly preferred embodiment has at least the following features: the male coupling part on the short edge comprises the aforementioned first locking element, wherein this first locking element is designed as a separate insert which is arranged in a recess in the male coupling part; and the male coupling part on the short edge comprises the aforementioned second locking element, wherein this second locking element is made of the material of the floor panel and in particular in one part therewith; and - the male coupling part on the short edge comprises a protruding lip, wherein in a distal side or edge of this lip the recess is arranged in which the insert is located and wherein the second locking element of the male coupling part on the short edge is designed in the shape of a protrusion on the underside of the protruding lip.
    Preferably, the underside of the protruding lip distally of the protrusion has a portion that rests on the female coupling part on the long edge in a coupled state between these coupling parts. This portion is located proximally of a closing surface defined between the respective coupled edges. Such support offers the advantage that the risk of height differences that could arise as a result of stepping over the floor panels can be minimized or even avoided. The tangent line that is defined where the said part is supported by the respective female coupling part is preferably oriented horizontally or substantially horizontally.
    In particular, a space is present on the underside of the protruding lip between this lip and the respective female coupling part. This space preferably extends continuously between the aforementioned part of the protruding lip that rests on the female coupling part and where the second locking elements work together.
    It is particularly advantageous if the male coupling part at the short edge can also be inserted into the female coupling part at the long edge by means of a horizontal or substantially horizontal snap movement. With such a snap movement the relative male coupling part is moved relatively seen towards the female coupling part in a direction perpendicular to the relevant edges and inserted into the plane or substantially in the plane of the floor panels and into the female coupling part with the occurrence of a snap effect. The fact that such a snap movement is possible provides more options for installation, as will appear from the detailed description.
    Performing the snap movement can be facilitated by providing the female coupling part with an elastically bendable part. This elastically bendable part can then be elastically bent when the snap movement is carried out and thus, as it were, make the opening in the female coupling part temporarily larger for introducing the male coupling part therein. Use can for instance be made of an elastically bendable lower lip.
    In order for the second locking elements to engage smoothly one behind the other when performing the snap movement, it is advantageous to provide an oblique guide surface on the underside of the male coupling part. This guide surface then preferably cooperates with the distal end of the female coupling part and in particular with the upper side thereof when performing the snap movement. For example, the distal side or edge of the aforementioned protrusion on the underside of the male coupling part can be designed as such a guide surface.
    It is further noted that the male coupling part on the short edge preferably fits exactly in the female coupling part on the long edge or can even take place with some play therein. In other words, there is therefore preferably no tension force which presses the respective short and long edge together at the top sides thereof. This makes it possible to compensate for any non-squareness of the floor panels. However, the invention does not exclude the presence of such tensioning force. If it is nevertheless present, it can be designed on the basis of the principle described with reference to Figure 23 of document WO 97/47834.
    The coupling parts on the pair of long edges are preferably designed in the form of a tooth and a groove, respectively, bounded by an upper and a lower lip, wherein the tongue and groove are provided with locking elements which, in a coupled state of the tooth and groove counteracting its moving apart in the horizontal direction. The horizontal direction is here understood to mean the direction perpendicular to the relevant edges and lying in the plane of the floor panels. Such coupling parts are known per se from, inter alia, the document WO 97/47834.
    The lower lip preferably projects beyond the upper lip. It is preferred that this lower lip comprises a locking element which is then preferably located in the part of the lower lip that projects beyond the upper lip. This locking element then cooperates in the coupled state with a locking element which is located on the underside of the tooth.
    Where they cooperate, the locking elements on the tongue and groove preferably define a tangent line that runs upwardly away from the groove. This tangent line therefore preferably concerns an oblique tangent line. It preferably makes an angle with the vertical that is less than 45 degrees and more preferably less than or equal to 30 degrees.
    Preferably, the top of the tooth, in the coupled state, cooperates with the bottom of the upper lip. This cooperation results in the realization of a lock in the vertical direction. Where these top and bottom work together, a tangent line is preferably defined that is oriented horizontally or substantially horizontally.
    The tooth, in the coupled state, preferably extends over a distance of at least 1/6 times the total thickness of the floor panel below the upper lip. This distance is even more preferably at least 1/4 times the total thickness of the floor panel and more preferably even at least 1/3 times the total thickness of the floor panel. It is clear that this distance is hereby measured in the direction perpendicular to the relevant edges and in the plane of the floor panels. Because the tooth extends relatively far below the upper lip, a firm vertical lock is obtained. This sturdy locking is certainly desirable along the linked long edges.
    The bottom side of the tooth preferably has a part with which the tooth in the coupled state rests on the top side of the lower lip. This portion is preferably at least partially distanced from a closing surface defined between the respective coupled edges. This part is preferably located completely distant from the closing surface mentioned. The support effect ensures that the tooth cannot be pressed further down. This offers, among other things, the advantage that the risk of height differences that could arise as a result of stepping over the floor panels can be minimized or even avoided.
    It is further noted that the aforementioned first locking element of the female coupling part on the long edge is preferably formed by the described upper lip.
    It is further noted that the second locking element of the female coupling part on the long edge preferably relates to the described locking element on the groove.
    The coupling parts on the pair of long edges, including the locking elements, are preferably made of the material of the floor panel and in particular in one part therewith.
    In a particularly advantageous embodiment, the male coupling part on the long edge can also be added to the long edge via a horizontal or substantially horizontal snap movement in the female coupling part. With such a snap movement, the male coupling part is moved relative to the female coupling part in a direction perpendicular to the relevant edges and inserted into the plane or substantially in the plane of the floor panels and into the female coupling part with the occurrence of a snap effect. The fact that such a snap movement is possible provides more options for installation, as will appear from the detailed description.
    Performing the snap movement can be facilitated by providing the female coupling part with an elastically bendable part. This elastically bendable part can then be elastically bent when the snap movement is carried out and thus, as it were, make the opening in the female coupling part temporarily larger for introducing the male coupling part therein. Use can for instance be made of an elastically bendable lower lip.
    In order for the locking elements on the tongue and groove to engage smoothly one behind the other when performing the snap movement, it is advantageous to provide an inclined guide surface on the underside of the tongue. This guide surface then preferably cooperates with the distal end of the female coupling part and in particular with the upper side thereof when performing the snap movement.
    In a special embodiment, the coupling parts on the pair of long edges are configured such that, in the coupled state, they provide a tensioning force which presses the coupled long edges towards each other on their upper sides. This principle is known per se from document WO 97/47834 and it is referred to in the art with the concept of bias. This bias can be realized on the basis of the principle illustrated in Figure 23 of the aforementioned WO 97/47834. For example, it is possible to work with a lower lip which is permanently elastically bent in the coupled state and thereby supplies the aforementioned tensioning force.
    The female coupling part on the short edge can have one or more features of the female coupling part on the long edge. Preferably this female coupling part on the short edge is even identical or almost identical to the female coupling part on the long edge.
    The male coupling part on the long edge can preferably also be inserted in the female coupling part on the short edge by a horizontal or substantially horizontal snap movement. As will appear from the detailed description, this provides more options for installation.
    The inventor has found that the present invention can be applied particularly advantageously to floor panels with a substrate made on the basis of a plastic such as polyvinyl chloride, polyethylene, polypropylene, polyethylene terephthalate and / or polyurethane. After all, these floor panels appear to undergo drastic dimensional changes at changing temperatures. These can lead to the floor covering swelling up and even to the moving floor panels moving apart. However, with the present invention, the risk of this can be minimized by the sturdy locking that can be provided between the edges.
    The substrate of these floor panels may or may not be multi-layered, but preferably comprises at least one substrate layer which is designed on the basis of a composition which has one or more of the following characteristics insofar as they are not contradictory: - The composition comprises at least one thermoplastic plastic. The composition comprises at least one plastic such as polyvinyl chloride, polyethylene, polypropylene, polyethylene terephthalate, polyurethane and / or an elastomer. The composition comprises one or more plasticizers in an amount of less than 20 phr and preferably in an amount between 5 and 15 phr. If such an amount of plasticizers is used, it is a substrate layer of the rigid or rigid type. - The composition comprises one or more plasticizers in an amount of at least 20 phr. In this case it concerns a substrate layer of the flexible or flexible type. - The composition comprises an inorganic filler such as chalk, talc and / or limestone. - The composition comprises an organic filler such as wood, bamboo and / or cork particles. - The composition comprises a mineral filler such as ceramic. - The composition comprises mineral fiber structures such as fibers of glass, tal and / or wollastonite.
    It is further noted that the presence of a substrate layer of the rigid type, i.e. with an amount of plasticizer of less than 20 phr, benefits the dimensional stability of the floor panels. This rigid substrate layer then ensures an extremely stable floor covering in cooperation with the sturdy locking.
    The substrate layer is optionally foamed. The advantage of this is that the density of the substrate layer can be reduced. This way, savings on raw materials and energy can be achieved. As well as foaming, the substrate layer can be assigned new properties such as in terms of comfort and more importantly in terms of dimensional stability.
    It is further noted that the substrate layer can be manufactured in various ways. For example, the substrate layer can be produced by scattering, extrusion, injection molding, calendering and / or coating techniques.
    The substrate can be composed of several substrate layers. These substrate layers can be made on the basis of a composition as described above, but they need not be identical to each other. The substrate layers may, for example, differ based on the amount of plasticizers employed. This may involve the combination of a flexible substrate layer with a rigid substrate layer.
    In a particularly preferred embodiment, the floor panels are of the so-called Luxury Vinyl Tile (LVT) or Wood Plastic Composite (WPC) type. For example, they concern floor panels that are designed as described in the document US 9,156,233 B2.
    Possibly the substrate is provided with a reinforcement layer such as a glass fiber cloth or a glass fiber or a glass net. This reinforcement layer is then preferably incorporated in the substrate. This means that the reinforcement layer is then bounded on both the top and bottom thereof by the material of the substrate. This reinforcement layer helps to increase the dimensional stability of the floor panels and thus contributes to the prevention of crack and slit formation in the floor covering in a herringbone pattern. It is noted that the substrate may be provided with several reinforcement layers, whether or not incorporated.
    The thickness of the floor panels is preferably essentially, that is to say half or more, formed by the substrate.
    The thickness of the floor panels is preferably between 2 and 8 mm and more preferably between 3 and 6 mm. This allows the floor panels to be made sufficiently thin, while still showing sufficient strength and stability.
    The floor panels are preferably decorative. To this end, they can be composed of a substrate and a top layer located above the substrate and comprising a decor. This decor preferably has a motif or pattern that can, for example, simulate a natural product such as wood, stone or ceramic. This concerns, for example, a wood motif or pattern. This motif or pattern can then, for example, simulate wood grain or pores.
    The decor is preferably a print that is applied directly or indirectly to an underlying layer of the floor panel. When the print is not applied directly, it is then typically applied to a carrier sheet. This carrier sheet may, for example, be a plastic film such as a polyvinyl chloride film, polyurethane film, polypropylene film, polyethylene terephthalate film or polyethylene film. Preferably, the carrier sheet is connected to the substrate or other layer of the top layer via a thermal laminating process. When applying the print directly to an underlying layer of the floor panel, the so-called direct print, it is not excluded that it is applied to a primer or primer provided on the underlying layer. For the direct print, a digital printer such as an inkjet printer is preferably used.
    The top layer preferably also comprises a transparent or translucent wear layer located above the decor. This wear layer then forms a protection for the decor. For example, it is a plastic-based wear layer which is applied either as a film, whether or not together with the aforementioned printed film, for example by means of a thermal laminating process, or is applied in liquid form and subsequently applied to the substrate or another layer of the top layer. cured. If the wear layer comprises a film, it is preferably a thermoplastic film, in particular a polyvinyl chloride film, a polyurethane film, a polypropylene film, a polyethylene terephthalate film or a polyethylene film.
    The top layer can be finished with a lacquer layer, which is applied as a liquid layer on the aforementioned wear layer and / or the aforementioned decor and is subsequently cured. It is preferably a lacquer layer that can be cured by UV light or excimer radiation or a layer that can be cured by raising the temperature. This latter layer can, for example, use blocked isocyanates as a crosslinker. Preferably a lacquer layer is applied on top of the optional wear layer, but according to an alternative the lacquer layer can function as a wear layer.
    The top layer can still be provided with indentations that may or may not be in register with the decor. For this purpose a roller can be used as described per se in PCT / IB2015 / 055826. The impressions provide the floor panels with a relief such that they can better simulate a natural structure such as a wood structure. The impressions can for instance be made according to a wood grain pattern.
    The floor panels can comprise, in addition to the substrate and the top layer, a counter layer which is located under the substrate. The counter layer can for instance be made on the basis of cork or on the basis of a thermoplastic plastic, which is preferably of the flexible type. Such a rather soft counter layer can assign new properties to the floor panels, for example in terms of comfort and sound absorption. In particular, the counter layer forms a layer with acoustic properties. The counter layer can, for example, contribute to reducing the noise production of the floor panels, for example when it is walked over.
    As is apparent from the foregoing, the invention primarily relates to floor panels which are built up from a substrate which is designed on the basis of a plastic such as polyvinyl chloride, polyethylene, polypropylene, polyethylene terephthalate and / or polyurethane. But the invention is not limited to such floor panels. For example, it is not excluded that the invention is applied to floor panels with a wood-based substrate such as an MDF or HDF substrate. The invention can also be applied to floor panels with a wood-based substrate and a top wooden layer such as a wood veneer top layer. This concerns floor panels of the so-called engineered wood type.
    The fact that the set of floor panels is suitable for forming a floor covering in a herringbone pattern implies that this set consists of at least two types of floor panels. The coupling parts of the one type of floor panels are herein mirrored on one pair of edges relative to the coupling parts of the other type of floor panels on that same pair. It is better worded that the location of the coupling parts is mirrored.
    The present invention still relates to a method for installing the set of floor panels. This set consists of at least two types of floor panels, with the coupling parts of one type of floor panels mirrored on one pair of edges relative to the coupling parts of the other type of floor panels on the same pair. The method comprises at least the following steps: - forming a first row by coupling floor panels of the first type to floor panels of the second type, short edge against long edge; and - forming at least a second row on the first row by coupling floor panels of one type to floor panels of the other type, short edge against long edge, wherein the floor panels from the second row are installed via a single turning movement.
    The application of this method provides a particularly smooth installation of the floor covering in a herringbone pattern. After all, the floor panels from the second row and any subsequent rows can all be installed by only making use of the user-friendly rolling movement, which is also referred to in the field with the term folddown movement. In addition, the specific configuration of the floor panels ensures that in the resulting floor covering the risk of a height difference, gap or crack formation between the floor panels mutually is small or can at least be minimized.
    In a practical embodiment, the aforementioned second row is formed by inserting the male coupling part at the short edge of a first floor panel into the female coupling part at the long edge of a second floor panel in one and the same turning movement used to connect the male coupling part to the long edge of the first floor panel in the female coupling part to the long or short edge of a third floor panel. Any further rows can also be installed or laid in this way.
    It is noted that a horizontal lock means a lock that is active in the direction perpendicular to the respective coupled edges and in the plane of the floor panels. By vertical locking is meant again a locking which is active in the direction perpendicular to the plane of the floor panels.
    It is also noted that the term guide surfaces does not exclude the possibility that these guide surfaces are curved. In other words, they are not necessarily flat.
    It is further noted that the term closing surface indicates the surface that indicates the closure between the mutually coupled floor panels from a top view. In particular it concerns a vertical plane. Even with floor panels that are assembled with play, such a closing surface can still be defined. This is more a theoretical plane that indicates the closure when these floor panels are pressed towards each other.
    It is further noted that a rotational movement is to be understood to mean a movement in which the floor panel with the male coupling part is pivoted downwards from an inclined position relative to the floor panel with the female coupling part to insert the male coupling part into the female coupling part. It may be that in the inclined position the male coupling part has already been partially inserted into the female coupling part, but certainly not yet completely.
    By rotating downwards, the male coupling part is then completely inserted into the female coupling part.
    It is also noted that in addition to being suitable for being laid in a herringbone pattern, the floor panels can also be used to lay other patterns or patterns.
    It is clear that the characteristics with respect to the long edges can equally well be applied to the short edges, with those of the short edges then being applied to the long edges. In other words, the features mentioned with respect to the long edges can be projected on the short edges while those of the short edges are then projected on the long edges.
    Moreover, the invention is not limited to elongated rectangular floor panels, but it can be applied to floor panels of any shape. In this context, the features stated with respect to the pair of long and short edges can be applied respectively to a first pair of edges and a second pair of edges. For example, floor panels in the form of a parallelogram can be used.
    It is also noted that the invention is not limited to floor panels. It can be applied more broadly to any type of panels such as, for example, wall panels.
    According to a deviating aspect, the invention relates to a set of floor panels which is suitable for forming a floor covering, wherein the floor panels from the set are quadrangular and elongated and thus have a pair of long sides and a pair of short sides, wherein both the pair long sides if the pair of short sides is provided with mechanical coupling parts that allow the floor panels to be joined together, the floor panels from the set being in the form of an oblique parallelogram and the set consisting of at least two types of floor panels, the floor panels of the one type with regard to their shape are mirrored with respect to the floor panels of the other type, and wherein the coupling parts have the following characteristics: - the coupling parts on the long sides allow that a long side of a floor panel can be coupled to a long side of another floor panel of the same type via a turning movement; and - the coupling parts on the short sides allow a short side of a floor panel to be coupled to a short side of a floor panel of a different type in one and the same turning movement that is used to couple a long side of the first-mentioned floor panel with a long side of another floor panel of the same type as the first-mentioned floor panel.
    This deviating aspect allows the floor panels from the set to be installed in a herringbone pattern, via the folddown technique. An important advantage is that to form this herringbone pattern it is not necessary that the long sides are compatible with the short. Due to the parallelogram shape, the herringbone pattern can be laid by coupling the long sides of the panels of the same type together and linking the short sides of the panels of one type with the short sides of the panels of the other type. There is no need to connect a long side with a short side.
    The coupling parts on the long sides of both types of floor panels are preferably designed in the form of a tooth and a groove, the groove being bounded by an upper lip and a lower lip. The lower lip can protrude beyond the upper lip. The tongue and groove are preferably provided with locking elements which, when coupled, counteract the movement of the tongue and groove in the horizontal direction. Such coupling parts are known per se from the document WO 97/47834.
    The coupling parts on the short sides of both types of floor panels are preferably designed as a downwardly directed upper hook-shaped section and an upwardly directed lower hook-shaped section. The upper hook-shaped portion comprises a lip with a downwardly directed locking element and the lower hook-shaped portion a lip with an upwardly directed locking element. In the coupled condition, these locking elements counteract the movement of the hook-shaped parts in the horizontal direction.
    The hook-shaped parts preferably also effect a vertical locking in the coupled state. This is preferably done with the aid of a separate insert. This insert can be made of plastic. The insert preferably comprises a locking part that can be elastically brought into a locking position. This locking part preferably ends up automatically in the locking position during the coupling movement between the short sides. Such an insert is known per se from the documents WO 2005/054599, WO 2008/068245 and WO 2009/066153.
    The insert may be located in a recess in the lower or upper hook-shaped portion. It then cooperates in a coupled state with a locking element on the other hook-shaped portion to realize the vertical locking. This locking element is preferably made in one piece with the floor panel. The recess is preferably provided in the upper hook-shaped portion and then in particular in the distal side of this hook-shaped portion.
    It is not excluded that the vertical locking at the hook-shaped portions is realized only by locking elements formed in one piece with the floor panel.
    It is noted that "mechanical coupling parts" is understood to mean coupling parts that allow a mechanical locking. No glue or the like is required for locking. But the use of glue is not excluded.
    It is also noted that a "slanting parallelogram" is understood to mean a parallelogram whose adjacent sides are different in length and include a non-right angle.
    The set according to the deviating aspect can exhibit one or more of the characteristics described above before the introduction of this aspect. And this in so far as no contradictions arise. It mainly concerns the characteristics with regard to the coupling parts on the long sides, the characteristics with regard to the male coupling part on the short side, which can be applied to the upper hook-shaped part of the deviating aspect, and the characteristics with regard to the substrate , the top layer and the thickness of the floor panels.
    With the insight to better demonstrate the features of the invention, a number of preferred embodiments are described below as an example without any limiting character, with reference to the accompanying drawings, in which: - figure 1 shows in top view two floor panels from a set according to the invention, as well as a partially finished floor covering in herringbone pattern; figure 2 shows an enlarged cross-section according to line II-II in figure 1 and also shows how the coupling parts shown in this cross-section can be joined together; figure 3 shows an enlarged cross-section according to line III-III in figure 1 and also shows how the coupling parts shown in this cross-section can be joined together; figure 4 shows a variant on the coupling parts shown in figure 2; figure 5 shows a method according to the invention for installing several of the floor panels of figure 1 in herringbone pattern; figure 6 shows enlarged and in perspective what is indicated by F6 in figure 5; figure 7 shows an alternative to the method of figure 5; figure 8 shows a top view of a floor covering in herringbone pattern realized with the set of floor panels according to the deviating aspect of the invention; figure 9 shows an enlarged cross-section along line IX-IX in figure 8; figure 10 shows an enlarged cross-section along line X-X in figure 8; and - figure 11 shows how the floor panels from figure 8 can be connected.
    Figure 1 shows in top view two floor panels 1A-1B from a set of floor panels according to the invention. These floor panels 1A-1B are suitable for forming a floor covering in a herringbone pattern, as will appear from what follows.
    Figure 1 also shows a partially finished floor covering 1 in a herringbone pattern. Several of the floor panels 1A-1B are used in this floor covering 1.
    The floor panels 1A-1B are elongated rectangular and thus have a pair of long edges 2-3 and a pair of short edges 4-5. Both the long and the short edges 2-3-4-5 are provided with mechanical coupling parts 6-7-8-9 that enable the coupling of several such floor panels 1A-1B to each other. One long edge 2 is provided with a male coupling part 6 and the other long edge 3 is provided with a female coupling part 7. The one short edge 4 is provided with a male coupling part 8 and the other short edge 5 is provided with a female coupling part 9.
    It is clear from Figure 1 that the floor panel IA is of a different type than the floor panel 1B. Namely, the location of the coupling parts 6-7-8-9 in the floor panel IA is mirrored relative to the location of the coupling parts 6-7-8-9 in the floor panel 1B.
    The mechanical coupling parts 6-7-8-9 will be described with reference to Figures 2 and 3.
    Figure 2 shows a cross-section along the line II-II in Figure 1. This figure therefore shows what the coupling parts 7-8 look like.
    Moreover, figure 2 also shows how these coupling parts 7-8 can be inserted into each other.
    The male coupling part 8 can be inserted into the female coupling part 7 by means of the downward movement M.
    In addition, the male coupling part 8 can be inserted into the female coupling part 7 in one and the same turning movement that is used to insert the male coupling part 6 into the female coupling part 7 or 9 of another floor panel. This then concerns the so-called folddown movement. Exactly what this coupling movement then looks like is described with reference to Figure 6.
    The male coupling part 8 can also be inserted into the female coupling part 7 by means of a horizontal or substantially horizontal snap movement S1.
    The male coupling part 8 and the female coupling part 7 effect both a locking in the horizontal direction H and a locking in the vertical direction V.
    The male coupling part 8 comprises a locking element 10 which cooperates with the locking element 11 of the female coupling part 7 to effect the locking in the vertical direction V.
    In the example, the locking element 10 is designed as a separate insert.
    Where the insert cooperates with the locking element 11, a tangent line R1 is defined which runs upwardly in the direction away from the female coupling part 7. This tangent line R1 forms an angle A1 with the horizontal, which is preferably smaller than 45 degrees. In the example shown, the angle A1 is approximately equal to 38 degrees.
    The insert is arranged in a recess 12 in the male coupling part 8. In the example, this recess 12 is arranged in a distal side or edge 13 of the male coupling part 8.
    The insert comprises a locking part 14 which, when performing the coupling movement, ends up in a locking position by performing a lateral movement. In the example, this locking part 14 is connected via a part 15 to a fixing part 16 with which the insert is arranged in the recess 12. The part 15 is made of another more flexible or more elastic material than the locking part 14 and the fixing part 16. This part 15 allows the locking part 14 to carry out the aforementioned lateral movement. This lateral movement here relates to a lateral rotation or rotation movement which is in particular two-fold.
    In the coupled state, the locking element 22 cooperates with the underside of the upper lip 14. Where they cooperate, a tangent line R2 is defined which makes an angle A2 different from zero with the horizontal.
    The male coupling part 8 further comprises the locking element 17 which cooperates with the locking element 18 to effect the aforementioned locking in the horizontal direction H.
    The locking element 17 is made from the material of the floor panel and in one part therewith.
    Where the locking elements 17-18 cooperate, a tangent line R2 is defined which runs upwardly in the direction away from the female coupling part 7. This tangent line R2 forms an angle A2 with the vertical which is preferably smaller than 45 degrees and more preferably smaller is then or equal to 30 degrees. In the example shown, the angle A2 is approximately equal to 30 degrees.
    In general, the male coupling part 8 here comprises a protruding lip 19. The recess 12 is arranged in the distal side or edge 13 of this lip 19. The locking element 17 is in the form of a protrusion on the underside of the lip 19.
    The underside of the lip 19 has a portion 20 distally from the protrusion with which it is supported on the female coupling part 7. This portion 20 is located proximal to the closing surface Y1 defined between the coupled edges 3 and 4.
    A space 21 is present between the underside of the lip 19 and the female coupling part 7. This space 21 continuously extends between the portion 20 and where the locking elements 17-18 work together.
    In the example, the male coupling part 8 fits precisely into the female coupling part 7. This has the consequence that no tensioning force is present in this coupling which presses the edges 3-4 towards each other on their upper sides. This has the advantage that even with non-right-angled floor panels, these edges 3-4 can still be easily connected to each other. It may even be more advantageous for the male coupling part 8 to fit into the female coupling part 7 with some play.
    Figure 3 shows a cross-section along the line ΠΙ-ΙΙΙ in Figure 1. This figure therefore shows what the coupling parts 6-7 look like.
    Moreover, figure 3 also shows how these coupling parts 6-7 can be put together.
    The male coupling part 6 can be inserted into the female coupling part 7 by means of the turning movement W.
    The male coupling part 6 can also be inserted into the female coupling part 7 by means of a horizontal or substantially horizontal snap movement S2.
    The coupling parts 6-7 are respectively designed as a tooth 22 and a groove 23. The groove 23 is bounded by an upper lip 24 and a lower lip 25. The tooth 22 and the groove 23 are provided with locking elements 26-18 which mutually moving the tooth 22 and groove 23 in the horizontal direction H.
    The lower lip 25 projects beyond the upper lip 24. In the part of the lower lip 25 that extends beyond the upper lip 24, the lower lip 25 comprises the locking element 18. This locking element 18 cooperates with the locking element 26 on the underside of the tooth. »
    Where the locking elements 26-18 cooperate, a tangent line R3 is defined which runs upwardly in the direction away from the groove 23. This tangent line R3 forms an angle A3 with the vertical which is preferably smaller than 45 degrees and even more preferably smaller is then or equal to 30 degrees. In the example, the angle α A3 is approximately equal to 30 degrees.
    The upper side of the tooth 22 cooperates with the lower side of the upper lip 24. Where this upper and lower side cooperates, a tangent line R4 is defined which is situated horizontally or substantially horizontally.
    The tooth 22 extends below the upper lip 14 over a distance D1 of at least 1/6 times the total thickness T of the floor panel and preferably over a distance D1 of at least 1/4 times the total thickness T of the floor panel and still more preferably even over a distance D1 of at least 1/3 times the total thickness T of the floor panel. In the example, the distance D1 is approximately 1/3 times the thickness T.
    The underside of the tooth 22 has a part 27 with which the tooth 22 rests on the top of the lower lip 25. This portion 27 is at least partially distanced from the closing surface VI defined between the coupled edges 2-3. In the example, this part is even completely distant from the closing face V1.
    It is clear that the first locking element 11 of the female coupling part is formed by the upper lip 24 and the second locking element 18 relates to the locking element on the lower lip 25. )
    The coupling parts 6-7 are made from the material of the floor panel and in one part therewith.
    It is further noted that the coupling parts 6-7 can be configured such that, in the coupled state, they provide a tensioning force which presses the coupled edges 2-3 together at their upper sides. As already described in the introduction, the principle from Figure 23 of document WO 97/47834 can be used for this. The lower lip 25 can then, for example, be permanently bent downwards in the coupled state.
    In the example, the female coupling part 9 on the short edge 5 is of identical design to the female coupling part 7 on the long edge 3. It is therefore not explicitly shown.
    Since the coupling parts 7 and 9 are identical, the male coupling part 6 can therefore be inserted into the female coupling part 9 by means of the turning movement W, as well as by means of the snap movement S2.
    Figure 4 shows another variant on the male coupling part 8. In this variant, the locking element 10 is made of the material of the floor panel and is formed in one part therewith.
    The floor panels 1A-1B are preferably constructed at least from a substrate 28 and a top layer 29 located above the substrate 28. The substrate 28 can be designed as described in the introduction and is preferably made on the basis of a composition comprising at least one plastic such as polyvinyl chloride, polyethylene, polypropylene, polyethylene terephthalate, polyurethane and / or elastomer. The top layer 29 preferably comprises a decor, as well as a transparent or translucent wear layer located above the decor. The detailed structure of the top layer 29 is not shown in Figures 2 to 4.
    The thickness T of the floor panels 1A-1B is preferably between 2 and 8 mm, with a thickness T between 3 and 6 mm being even more desirable.
    How the floor covering 1 shown in Figure 1 can be achieved is described with reference to Figures 5 to 7.
    Figure 5 shows a first possible method for forming the floor covering 1 of figure 1.
    Forming the first row X is done by linking floor panels IA to floor panels 1B. The short edge 4 is coupled to the long edge 3.
    The second row Y is formed by in a first step S1 coupling the floor panels 1B with the long edge 2 to the long edge 3 and the short edge 5 of the already installed floor panels 1B-1A from the first row X by means of the turning movement W. In addition, in the same movement W the short edge 4 of the floor panel 1B can be coupled to the long edge 3 of the already installed floor panel IA from the first row X. Exactly what the aforementioned turning movement W looks like is illustrated in Figure 6. This figure shows enlarged and in perspective what is indicated by F6 in figure 5.
    Analogously, in a second step S2, the floor panels IA can be laid, which leads to the completion of the second row Y. It is clear that further rows of the floor covering can be laid in the same way.
    Figure 7 shows a second possible method for forming the floor covering 1 of figure 1. This method is possible in that the coupling parts 6-7-8-9 also allow a horizontal or substantially horizontal snap coupling movement.
    In Figure 7, a start is made with laying a first row X of the floor covering, which is only partially finished.
    Then, in a step S3, the second row Y is already partially laid. The floor panel 1B with the long edge 2 is then coupled to the long edge 3 of the already installed floor panel 1B from the first row X by means of the turning movement. W. In the same movement W, the short edge 4 of the floor panel 1B can be coupled to the long edge 3 of the already installed floor panel IA from the first row X. In an analogous manner, the floor panel IA is placed in the second row Y.
    In a next step S4, further work is being carried out on the first row X. To install the floor panel IA, clever use is made of the possibility of snapping. For example, the long edge 2 of the floor panel 1A is snapped into the short edge 5 of the floor panel 1B from the first row X and the short edge 5 into the long edge 2 of the floor panel 1B is snapped from the second row Y. According to an alternative the rolling snap technique can be used, wherein the long edge 2 is then coupled via a rolling movement to the short edge of the floor panel 1B from the first row X and then the short edge 5 is snapped into the long edge 2 of the floor panel from the second row Y. The following floor panel 1B can be placed in the first row X by snapping the long edge 3 on the short edge 4 of the floor panel IA then already installed.
    Thereafter, the installation of the second row Y can be continued again in an analogous manner as in the step S3.
    Figure 8 shows in top view a floor covering 30 in herringbone pattern, or at least a part of this floor covering wherein this pattern is realized with a set of floor panels 31 according to the deviating aspect. The floor panels 31 have the shape of an oblique parallelogram. They have a pair of parallel long sides 32-33 and a pair of parallel short sides 34-35. The long sides 32-33 enclose a non-right angle with the short sides 34-35. The set consists of two types of floor panels 31, namely the floor panels 31A and the floor panels 31B. The floor panels 31A are mirrored in shape with respect to the floor panels 31B. The floor panels 31 are provided on both their long and short sides 32-33-34-35 with mechanical coupling parts with which the floor panels 31 are coupled to each other. The shape of these coupling parts is further described with reference to Figures 9 and 10. It is clear from Figure 8 that the herringbone pattern is formed without coupling a long side with a short side. The long sides 32-33 of the one type of floor panels 31A are coupled to each other, the long sides 32-33 of the other type of floor panels 31B are coupled to each other, and the short sides 34-35 of the one type of floor panels 31A are coupled to the short sides 34-35 of the other type of floor panels 31B. A compatibility between the long sides 32-33 and the short sides 34-35 is therefore not required.
    Figure 9 shows the coupling parts 36-37 on the long sides 32-33 in the coupled state. These coupling parts 36-37 allow the long side 32 of a floor panel 31A or 31B to be coupled to the long side 33 of another floor panel 31 of the same type via the turning movement W. The coupling parts 36-37 are designed as a tooth 38 and a groove 39. The groove 39 is delimited by an upper lip 40 and a lower lip 41. The lower lip 41 extends beyond the distal end of the upper lip 40. Locking elements 42-43 are provided for locking in the horizontal direction H. These locking elements 42-43 consist of a protrusion 44 on the underside of the tooth 38 and an upwardly directed locking element 45 as part of the lower lip 41.
    It is noted that the coupling parts 36-37 may also allow the long side 32 of a floor panel 31A or 31B to be coupled to the long side 33 of another floor panel 31 of the same type by means of a horizontal or substantially horizontal translation. or snap motion S. With this motion S, a snap effect occurs. This snap effect is the result of the elastic movement EM which the lower lip 41 carries out during the translation movement S.
    It is possible that the lower lip 41 is elastically bent in the coupled state and thus provides a tensioning force which presses the long sides 32-33 together. This is also called "bias" and is known per se from document WO 97/47834. In Figure 9 this is the case due to the presence of the lip 41 bent downwards.
    It is further noted that it is not necessary for the coupling parts 36-37 on the long sides 32-33 of the one type of floor panels 31A to be identical to the coupling parts 36-37 on the long sides 32-33 of the other type of floor panels 31B, which is the case here. However, no compatibility is required between these coupling parts as is clear from Figure 8.
    Figure 10 shows the coupling parts 46-47 on the short sides 34-35 in the coupled state. These coupling parts 46-47 allow the short side 34 of a floor panel 31A or 31B to be coupled to the short side 35 of a floor panel 31 of the other type in one and the same winding movement W which is used around the long side 32 of the connect the first floor panel 31A or 31B to the long side 33 of another floor panel 31 of the same type as the first floor panel 31A or 31B. The turning movement W involves a downward coupling movement DM between the short sides 34-35. Exactly how this works is illustrated in Figure 11. In this figure, a floor panel 31B to be installed and the panels 31A and 31B already installed are shown. The floor panel 31B to be installed is brought into an inclined position, the tooth 38 on the side 32 of this panel 31B being partially inserted into the groove 39 on the side 33 of the installed panel 31B and the coupling part 46 on the short side 34 above the coupling part 47 on the short side 35 of the installed floor panel 31A. From this inclined position, the floor panel 31B to be installed is rotated downwards, according to the movement W, whereby both the long side 32 and the short side 34 of this panel 31B are coupled. The situation is analogous starting from a floor panel 3IA to be installed.
    The coupling parts 46-47 are designed as a downwardly directed upper hook-shaped portion 48 and an upwardly directed lower hook-shaped portion 49. The upper hook-shaped portion 48 comprises a lip 50 with a downwardly directed locking element 51 and the lower hook-shaped portion 49 a lip 52 with a upwardly directed locking element 53. The locking elements 51 and 53 provide for the locking in the horizontal direction H.
    The hook-shaped parts 48-49 also realize a locking in the direction V. For this purpose a separate insert 54 cooperates with the locking element 55. The insert 54 consists of three parts: a locking part 56, a connecting part 57 and a fixing part 58. The insert is made from plastic by co-extrusion. The connecting part 57 is designed to be more flexible than the other parts 56 and 58. It ensures that the locking part 56 can be elastically brought into the locking position. During the coupling movement, the locking part 56 performs a rotation movement R and it automatically enters the locking position. The insert 54 is arranged with the fastening part 58 in the recess 59. The recess 59 is provided in the distal side 60 of the upper hook-shaped portion 48.
    It is noted that the coupling parts 46-47 also allow that the short side 34 of a floor panel 31A or 31B can be coupled to the short side 35 of a floor panel 31 of the other type via a horizontal or substantially horizontal translational e-snap movement. , whereby a snap effect occurs with this movement. This snap effect is due to the elastic movement that the lip 52 performs during the translation movement.
    Furthermore, the coupling parts 46-47 also allow the short side 34 of a floor panel 31A or 31B to be coupled via a turning movement to the short side 35 of a floor panel 31 of the other type.
    It is possible that the lip 52 of the lower hook-shaped part 49 is elastically bent in the coupled state and thus provides a tensioning force which presses the short sides 34-35 together. This is also referred to as "pre-stressing" and is known in such a system with hook-shaped coupling parts from document BE 2015/5686.
    The present invention is by no means limited to the embodiments described above, but such methods, floor panels and carrier material can be realized according to different variants without departing from the scope of the present invention.
