DESCRIPTION REPORT OF THE INVENTION PATENT FOR PANEL TO FORM A COVERAGE.
[001] This invention relates to a panel, a cover formed by such panels, and a method for installing such panels.
[002] Firstly, the invention relates to floor panels, more particularly decorative floor panel to form a floor covering, however, it is not excluded to apply the invention with other forms of coverings, for example, as wall panels, panels ceiling and the like.
[003] The invention relates in particular to panels consisting of soft synthetic material, more particularly panels consisting of soft PVC (polyvinyl chloride), also called tiles or vinyl strips. Generally, the abbreviation LVT is still used for such tiles, which are responsible for the Luxurious Vinyl Canvas. Here, this refers particularly to vinyl tiles with a total core, said core whether or not composed of layers and substantially consisting of a PVC-based material, between recycled or non-recycled PVC.
[004] Synthetic material panels are known, among others, from US 2002/0189183. Here, reference is also made to US Patent Application No. 09 / 152,684, which is granted under US No. 6,306,318, and in which for the material, the use of PVC is established. The panels shown in US 2002/0189183 are formed in a mold. This technique shows the disadvantage that it is expensive and that the production rate is low. Furthermore, the panels obtained in this way are subject to tolerance deviations as a result of the fact that expansions can occur when removing the panels from the mold, as a consequence of this coupling means possibly formed on the margins, when installing the panels, it is difficult to fit each other, or are placed too loosely together.
Petition 870190034807, of 11/11/2019, p. 5/58
2/45 [005] A first objective of the invention is to offer solutions for coupling such PVC panels, or other soft synthetic material, to each other in an appropriate way, by means of appropriate coupling parts.
[006] In addition, the invention in general also relates to a panel, in particular a floor panel, which, at least on two opposite edges, comprises coupling parts of the type that allows two of these panels to be coupled to each other by means of of a downward movement of one panel in relation to another, in which these coupling parts form a first locking system, which perform a locking in the plane of the panels and perpendicularly to said margins, as well as forming a second locking system, which performs a lock perpendicular to the plane of the panels. A second objective of the invention is also to optimize panels of this type, so that the coupling parts offer new possibilities, and, among others, can also be applied with flexible material panels, more particularly so-called soft PVC panels.
The. Thus, according to a first aspect, the invention relates to a panel for forming a cover, more particularly a floor panel for forming a floor covering, which, at least on two opposite edges, comprises coupling parts of the type that allows two of these panels to be coupled to each other by moving downwards from one panel with respect to another; wherein these coupling parts form a first locking system, which makes a lock in the plane of the panels and perpendicularly to said margins, as well as forming a second locking system, which makes a locking perpendicular to the plane of the panels; with the characteristic that at least one of said parts of
Petition 870190034807, of 11/11/2019, p. 6/58
3/45 coupling is carried out at least partially in soft PVC, as well as at least partially in the form of a part in a milled profile of this soft PVC. By grinding the coupling parts at least partially from soft PVC, very precise tolerances can be maintained. In combination with the use of PVC then very controllable elastic properties can be transmitted to the coupling parts, whereby all good properties are obtained, with respect to a light coupling as well as with respect to the coupling force that can be realized by means of such coupling parts.
[007] According to a deviation mode, the detached parts, instead of using one or more grinding treatments, can also be carried out by one or more mechanical cutting treatments.
[008] In a preferred embodiment, the panel is realized as a flexible PVC panel, thus, at least with a PVC based substrate, and said coupling parts are integrally made of this substrate, preferably completely by means of a treatment mechanical cutting, more particularly by means of a grinding process.
[009] According to a second independent aspect, the invention relates to a panel for forming a cover, more particularly a floor panel for forming a floor covering, which, at least on two opposite edges, comprises coupling parts of the type that allows two of these panels to be coupled to each other by means of a downward movement of one panel in relation to another; where these coupling parts form a first locking system, which locks in the plane of the panels and
Petition 870190034807, of 11/11/2019, p. 7/58
4/45 perpendicular to said margins, as well as forming a second locking system, which performs a locking perpendicularly to the plane of the panels; wherein the first locking system is formed at least by a lower hook-shaped part directed upwards which is situated on one of the two said margins, as well as by a upper hooked part directed downwards which is situated on the margin opposite; and in which the lower hook-shaped part consists of a nozzle with a locking element directed upwards, wherein the upper hook-shaped part consists of a nozzle with a locking element directed downwards; with the characteristic that at least one of said hook-shaped parts is flexible with respect to the plane of the respective panel, so that the respective locking element can carry out a movement, more particularly a tilting movement, which makes it easier to couple the panels.
[0010] The panels according to this second independent aspect offer the advantage that they can be easily coupled on said margins, as the tilting movement provides the locking elements that can more easily engage one after the other, possibly without necessarily having to superimpose an instant effect.
[0011] It is observed that, as yet to be explained, the inclination directed in such a way can occur in such a hook-shaped part, as well as at a distance from it, in which the hook-shaped part in the last case then as the whole adopts a curved position.
[0012] According to a preferred feature of the second aspect, the panel is characterized in that the coupling means are configured in such a way that the locking element directed downwards is configured so that the locking element directed downwards must be brought through an opening between the locking element
Petition 870190034807, of 11/11/2019, p. 8/58
5/45 directed upwards and the locking part of the second locking system and that the locking element directed downwards and said opening are configured so that the locking element directed downwards fits more easily through said opening when at least at least one of said hook-shaped parts is tilted, compared to the case when one of the hook-shaped parts is tilted.
[0013] According to a third independent aspect, the invention relates to a panel for forming a cover, more particularly a floor panel for forming a floor covering; wherein this panel comprises a substrate of a soft PVC-based material; wherein this panel is rectangular, parallelogram or square, and thus comprises a first pair of opposite margins and a second pair of opposite margins; wherein both pairs of opposing margins comprise coupling parts that allow a plurality of such panels to be mutually coupled to each other; wherein these coupling parts on both pairs of margins form a first locking system which performs a locking on the plane of the panels and perpendicular to the respective margins, as well as forming a second locking system which performs a locking perpendicular to the plane of the panels; and wherein these coupling parts are substantially made of said substrate; with the characteristic that the coupling parts in the first pair of opposite margins are configured so that two of these panels can be coupled to each other on these margins by means of a rotating movement; and that the coupling parts on the second pair of opposite edges are configured so that two of these floor panels can be coupled to each other by means of a downward movement of one panel with respect to another, more particularly by means of the movement towards low obtained as a result of the rotating movement in the first pair of margins.
Petition 870190034807, of 11/11/2019, p. 9/58
6/45 [0014] According to the preferred modality, this floor panel is still characterized in that the second locking system in the second pair of margins consists of parts of the lock engaging behind each other, which can be brought one behind the another for its elasticity and / or mobility.
[0015] The panels according to the third aspect of the invention offer the advantage that, even by integrating the coupling parts on the second pair of sides in the substrate, the ideal properties are obtained to perform a coupling that allows a lock through a downward movement.
[0016] According to a fourth independent aspect, the invention relates to a panel for forming a cover, more particularly a floor panel for forming a floor covering; whereas, at least on two opposite margins, it comprises coupling parts of the type that allows two of these panels to be coupled to each other by means of a downward movement of one panel with respect to another; wherein these coupling parts form a first locking system, which makes a lock in the plane of the panels and perpendicularly to said margins, as well as forming a second locking system, which makes a locking perpendicular to the plane of the panels; wherein the first locking system is formed at least by a lower hook-shaped part directed upwards which is situated on one of the two said margins, as well as by a upper hooked part directed downwards which is situated on the margin opposite; wherein the lower hook-shaped part consists of a nozzle with a locking element directed upwards, where the upper hook-shaped part consists of a nozzle with a locking element directed downwards; and wherein the second lock system comprises parts of the lock which are situated near the end close to the lower hook-shaped part and the
Petition 870190034807, of 11/11/2019, p. 10/58
7/45 distal end of the upper hook-shaped part, respectively; characterized in that at least one of said parts of the latch of the second latch system is made of soft PVC.
[0017] Here, said parts of the lock are preferably made as a compressible part and preferably fixed.
[0018] More particularly, it is preferred here that the panel substantially consists of a substrate based on soft PVC and that said coupling parts are integrally realized in said substrate, wherein said parts of the latch are realized as fixed, possibly parts somewhat compressible.
[0019] Using soft PVC in a coupling system with coupling parts that can be joined by a downward movement, it is obtained that the coupling parts can move easily along one another during coupling.
[0020] According to a fifth independent aspect, the invention relates to a panel for forming a cover, more particularly a floor panel for forming a floor covering; wherein this panel is of the type that comprises a substrate of soft synthetic material; wherein this panel, at least on two opposite edges, comprises coupling parts of the type that allows two of these panels to be coupled to each other by means of a downward movement of one panel with respect to another; wherein these coupling parts form a first locking system, which makes a lock in the plane of the panels and perpendicularly to said margins, as well as forming a second locking system, which makes a locking perpendicular to the plane of the panels; wherein the first locking system is formed at least by a lower hook-shaped part directed upwards which is situated on one of the two said margins, as well as by a upper hooked part directed downwards which is situated on the margin opposite;
Petition 870190034807, of 11/11/2019, p. 11/58
8/45 characterized in that in said substrate, the reinforcement layer is present, which extends in the plane of the panel; that the lower hook-shaped part consists of a nozzle with a locking element directed upwards, whereas the upper hook-shaped part consists of a nozzle with a locking element directed downwards; and that at least one of said nozzles is configured in such a way that, seen in the cross section, it is at least on a certain free part of said reinforcement layer. Preferably, both nozzles are configured in this way.
[0021] The term reinforcement layer must be understood in a broad sense and still simply includes a layer that, for example, is applied as a basic carrier to create the vinyl structure.
[0022] As one or both of the nozzles, over at least a part of it, are kept free of such reinforcement layer, the advantage is obtained and such reinforcement layer cannot affect the bending in these parts in a disadvantageous manner.
[0023] It is observed that the invention also refers to all possible combinations of the aspects previously mentioned, in which two, three, four or all five said aspects are combined with each other. Here, all mathematically possible combinations of the five aspects can be taken into account.
[0024] According to the preferred modalities, the panels of one or more aspects previously mentioned also show as one or more of the additional characteristics listed below, inasmuch as these characteristics are not part of the basic characteristics of such aspect. These characteristics consist of:
- that at least said coupling parts, which are of the type that allows two of these floor panels to be coupled to each other by means of a downward movement of a

- that this panel is rectangular, parallelogram or square, and thus comprises a first pair of opposing edges and a second pair of opposing edges, in which both pairs of opposing edges comprise coupling parts that allow a plurality of such panels to be mutually coupled one the other, in which these coupling parts on both pairs of margins form a first locking system which performs a locking on the plane of the panels and perpendicular to the respective margins, as well as forming a second locking system which performs a locking perpendicular to the plane of the panels, and in which the coupling parts in one of both pairs of margins are thus formed by said coupling parts which are of the type that allows two of these floor panels to be coupled together by means of a movement for under one panel in relation to another;
- that the panel substantially consists of a substrate and

10/45 that the coupling parts in both pairs of margins are made substantially integrally of this substrate;
- that the substrate substantially consists of soft PVC, in which possibly a reinforcement layer is incorporated;
- that the substrate substantially consists of soft PVC, with the exception of possible upper layers, back layers and intermediate layers, which may consist of another material.
[0025] According to a particular aspect of the invention, the coupling parts and / or the substrate and / or the entire panel consists of a soft synthetic material other than PVC, preferably having an elasticity comparable to that of soft PVC. It is clear that similar advantages are obtained. Also, material compositions are possible, for example, soft PVC with other materials, such as fillers. PVC can consist of new material as well as recycled PVC. Of course, this also applies to the modalities that follow.
[0026] The panels of the invention are preferably made in the form of rectangular parallelogram strips. The dimensions can vary widely.
[0027] With respect to the thickness of the modalities referred to above as well as below, this preferably varies between 3 and 10 mm, and even better between 4 and 7 mm.
[0028] On the decoration side, they comprise a decorative layer, which can carry any image. In a practical way, the image represents a wooden theme. More particularly, on each panel, the appearance of a wooden plank is represented.
[0029] Other additional features will become clear from the detailed description and the claims. It is observed that all subsidiary characteristics can be combined arbitrarily with
Petition 870190034807, of 11/11/2019, p. 14/58
11/45 the main characteristics of the respective basic aspects.
[0030] In accordance with a sixth independent aspect, the invention provides a method for installing panels, more particularly floor panels, in which these panels are rectangular, parallelograms or squares, and thus comprise a first pair of opposite edges and a second pair opposite margins; in which both pairs of opposite margins comprise coupling parts, which form a first locking system which makes a lock in the plane of the panels and perpendicular to the respective margins, as well as forming a second locking system which makes a lock perpendicular to the plane of the panels. panels; wherein the coupling parts on the first pair of opposite edges are configured so that two of these floor panels can be coupled to each other on these edges by means of a rotating movement; wherein the coupling parts in the second pair of opposing edges are configured so that two of these floor panels can be coupled to each other by means of a downward movement of one panel with respect to another, more particularly by means of the movement towards low that is obtained as a result of the rotating movement in the first pair of margins; wherein in the second pair of margins, the locking system is formed by at least a lower hook-shaped part directed at one of the two said margins, as well as a lower hook-shaped part directed downwards. located on the opposite bank; and in which the lower hook-shaped part consists of a nozzle with a locking element directed upwards, wherein the upper hook-shaped part consists of a nozzle with a locking element directed downwards; with the characteristic that in the second pair of margins coupling parts are applied that at least one of the nozzles, with respect to the plane of the panel in question, can be tilted from this plane, so that the locking element
Petition 870190034807, of 11/11/2019, p. 15/58
12/45 can make a movement, more particularly a tilt movement that facilitates the coupling of the panels, and that the method provides at least the following steps:
- installing a first panel directed to form part of a first row of panels;
- coupling a second panel to said first panel, in said first pair of margins, in which this second panel is directed to form part of a second successive row to said first row of panels;
- coupling in the second row a third panel to said second panel and to the first panel, in which the third panel is coupled to the first panel by means of a rotating movement, in which the third panel, from a position turned upwards, is brought substantially on the same plane as the first and second panels, in which, as a result of this movement and the downward pressure movement created therein, the hook-shaped parts engage one another between the third and the second panel;
- apply a base element to it;
- and, during pressing, as a result of using the base element, deforming, more particularly tilting, at least one of said nozzles so that coupling, as previously mentioned, is facilitated.
[0031] According to a variant, not specifically one or more nozzles are inclined, but one or more of the hook-shaped parts are inclined as a whole or locally, in which the inclination thus does not necessarily have to occur in the nozzles themselves.
[0032] This installation technique allows easy installation, without the need for tools. Other advantages, as well as preferred techniques, will become clearer from the detailed description.
Petition 870190034807, of 11/11/2019, p. 16/58
13/45 [0033] It is clear that the sixth aspect method shows its particular advantages when it is applied to install panels in the form of strips or tiles with a soft PVC base, which are supplied with said coupling parts.
[0034] According to a variant of deviation from the sixth aspect, the invention also relates to a method in which the technique described above, as well as the technique described below, in which a base element is applied and a slope is created, is applied to panels where in the first pair of margins the connection is made in another way than by means of a rotating movement. The essence in fact consists of the particular tilting technique that the coupling parts on one pair of margins, regardless of the way in which the other pair of margins is coupled.
[0035] In a preferred modality, the panels of the previously mentioned method are applied to also perform one or more of the first five aspects.
[0036] It is observed that soft PVC is a term that expresses that this refers to flexible PVC, in other words, PVC that is flexible in a relatively light way. The term soft PVC is generally known in the art. Such soft PVC consists of PVC which is made flexible, preferably by means of a plasticizer added during the production process. Depending on the amount of plasticizer added, different degrees of elasticity can certainly be obtained.
[0037] By a plasticizer, any agent must be understood, which, when added, results in a more flexible PVC. Typical examples are phthalate plasticizers and isosorbide plasticizers.
[0038] By the PCV that was plasticized, certainly, PVC can also be understood, or a PVC based composition, which has the characteristic that it is flexible, for example, that is why it is modified.
Petition 870190034807, of 11/11/2019, p. 17/58
14/45 [0039] Preferably, a flexibility will be applied which is such that, when a panel is tightened horizontally at one end, it will actually be tilted down under its own weight and possibly at a distance from the fixed part it will actually hang down completely, however, it certainly will not simply hang straight down after the fixed end, however, it will be quite flexible by manual force.
[0040] Also, it is noted that a number of basic independent aspects are not restricted to the use of PVC or other synthetic material. Thus, it is clear that these aspects can also be applied to panels of other materials.
[0041] Although the coupling system described here is particularly useful when applied to panels having a substrate based on synthetic material, and in particular PVC panels, with soft PVC it has been observed that in particular under the influence of heat, for example, radiation from the sun on a floor, considerable expansion can occur, with the result that with such soft PVC, there is no risk that the panels, on their edges, are pushed up against each other, which can result in these couplings, which they are the type that allows a connection by means of a downward movement, they are simply pushed against each other. According to a seventh aspect, a solution to this is offered.
[0042] In accordance with this seventh aspect, the invention relates to a panel for forming a cover, more particularly a floor panel for forming a floor covering; wherein this panel comprises a substrate of a soft PVC-based material; in which this panel is rectangular, parallelogram or square, and thus comprises a first pair of opposite margins and a second pair of opposite margins, in which both pairs of opposite margins comprise coupling parts that allow coupling a
Petition 870190034807, of 11/11/2019, p. 18/58
Plurality of such panels to each other; wherein these coupling parts, in both pairs of margins, form a first locking system making a lock in the plane of the panels and perpendicular to the respective margins, as well as forming a second locking system making a lock transverse to the plane of the panels; and wherein these coupling parts are substantially made of said substrate; characterized by the fact that the coupling parts of the first pair of opposite margins, as well as of the second pair of opposite margins are configured so that two of these panels can be coupled to each other on these margins by means of a rotating movement;
for this purpose, these coupling parts, in each of the two previously mentioned pairs of margins, consist of a tongue and a groove, as well as parts of the latch, which, in the coupled condition, prevent the separation of the tongue and groove;
and that in both pairs the groove is each time surrounded by a lower nozzle and an upper nozzle, whereby the lower nozzle extends laterally upward beyond the distal end of the upper nozzle.
[0043] By the tongue and groove directed in the seventh aspect, a tongue and groove system is directed in which the tongue and groove are so pronounced that they cannot be forced together by a manual downward motion and so they can be interconnected only in another way, for example, by a rotating motion and / or a switching motion.
[0044] As, in both pairs of margins, the coupling parts are supplied, which can be brought to each other by means of a rotating movement and which comprise a pronounced tongue and groove system, the panels can no longer be pushed out from each other in the upward direction in their
Petition 870190034807, of 11/11/2019, p. 19/58
16/45 margins, for this permanent coupling remains guaranteed. [0045] It is observed that until now, the application of the so-called angle connections in both pairs of margins of the soft PVC panels was impossible, as such panels, during the coupling, so they had to be subject to at least a number of operations of manual alternation in the longitudinal direction along the coupled margins, and as if assuming that they consist of soft PVC, in this case, thus, tongue and groove, would not allow such manual alternation operations due to the great friction between them. Against all assumptions, however, the inventor noted that it is actually still possible. Thus, through the seventh aspect, this damage is superimposed.
[0046] According to the preferred embodiment of the seventh aspect of the invention, the panel is characterized in that the lock parts previously mentioned in both pairs are provided with the lock surfaces, which are located at least partially in the part of the lower nozzle which is located beyond the distal end of the upper nozzle. Then, the tongue lock part can be easily brought behind the groove lock part when inserted by the swivel.
[0047] According to yet another preferred embodiment of the seventh aspect of the invention, the panel is characterized in that at least on a pair of edges, the tongue and the groove have a shape that provides, in the coupled condition of two of these panels, a space is present below the tongue, said space extending continuously below the tongue as at the tip of the tongue, at least to a location that is situated beyond the distal end of the upper nozzle. The use of such a space has the advantage that panels, during installation, can be easily moved along one another, as the risk of getting stuck and friction during installation is reduced. Also, due to this space, the insertion of the tongue in the groove is avoided.
[0048] Preferably, said space extends below the tongue
Petition 870190034807, of 11/11/2019, p. 20/58
17/45 over a length, measured parallel to the panel surface, which is at least 1.5 and even better at least 2 times the distance from the tip of the tongue to the distal end of the upper nozzle. At present, the risk of the occurrence of unwanted fixation between the panels during installation is reduced even further.
[0049] According to the seventh aspect, it is still preferred that the panel is parallelogrammed and thus has a long and short side, and that at least the margins of the short sides provide such space. This is particularly useful when the panels are installed using a technique called angle-angle technique, since the fixation will take place easily here, which, particularly in the case of panels consisting of soft PVC, can lead to situations that may present the installation pretty difficult.
[0050] According to a particular modality, the panel is characterized in that it is manually flexible in at least one direction so that it can be inserted, in the margins extending transversal to this direction, with a tongue over the lower nozzle of a panel anterior in the groove of this anterior panel, until the upper margins touch, and without tilting the lower nozzle of the anterior panel, in which the panel in question, on the margin located opposite the margin having said tongue, is tilted down until it touches the base surface. The advantage of this will become evident from the description below.
[0051] Still according to another modality of the seventh aspect, the panel is characterized in that it is manually flexible in at least one direction so that it can be inserted, in the margins extending transversal to this direction, with the tongue over the mouthpiece lower part of an anterior panel in the groove of this anterior panel, until the upper margins touch, and without inclination the lower nozzle of the anterior panel, in which the panel in question, on the margin located
Petition 870190034807, of 11/11/2019, p. 21/58
18/45 opposite the margin having said tongue, it is tilted downwards until it touches the base surface, and that the pair of margins extending across said direction refers to the same pair of margins as the pair of margins that provides the space previously mentioned. This combination of features is particularly useful for coupling the panels together using the angle-angle technique.
[0052] In a practical mode of the seventh aspect, both pairs of margins provide such space in the coupled condition.
[0053] According to another modality, the panel of the seventh aspect is characterized in that the tongue and groove of at least one pair of margins are made in such a way that, when two of these panels are presented to each other on these margins in a shape planar parallel, the tongue, at least with its tip, sits at least partially below the nozzle surrounding the upper side of the groove, without any inclination being already necessary. The other pair of margins then in the coupled condition preferably provides a space, as described here above.
[0054] Even only in the application of said space with panels that consist of a soft PVC-based material already results in a coupling system that is advantageous in relation to existing systems. In fact, it is clear that then even fixing takes place when coupling two of these panels, and the installation will become considerably easier. Accordingly, the invention, according to an eighth independent aspect, relates to a panel for forming a cover, more particularly a floor panel for forming a floor covering; wherein this panel comprises a substrate of a soft PVC-based material; wherein this panel is rectangular, parallelogram or square, and thus comprises a first pair of opposite margins and a second pair of opposite margins; where both pairs of opposite margins comprise parts of
Petition 870190034807, of 11/11/2019, p. 22/58
19/45 coupling that allows a plurality of such panels to be coupled to each other; wherein these coupling parts, in both pairs of margins, form a first locking system making a lock in the plane of the panels and perpendicular to the respective margins, as well as forming a second locking system making a lock transverse to the plane of the panels; and wherein these coupling parts are substantially made of said substrate; characterized by the fact that for this purpose, these coupling parts, at least one of the two pairs of margins previously mentioned, consist of a tongue and a groove, as well as parts of the lock, which, in the coupled condition, prevent the removal of the tongue and the groove;
said groove is each time surrounded by a lower nozzle and an upper nozzle, whereby the lower nozzle extends laterally upward beyond the distal end of the upper nozzle; and said tongue and groove have a shape that provides, in the coupled condition of the two of these panels, a space is present below the tongue, said space extending from the tip of the tongue continuously below the tongue at least to a location located beyond the distal end of the upper nozzle.
[0055] Preferably, the panel, according to the eighth aspect, is still characterized in that the tongue and groove, including the parts of the latch, are of the type that allows two of these panels to be interconnected at the respective margins by means of a rotating motion. In accordance with yet another preferred feature, said tongue and groove are made in such a way that, when two of these panels are presented to each other in these margins in planar parallel shape, the tongue, at least with its tip, sits at least partially below the nozzle surrounding the upper side of the groove, without any inclination being required.
Petition 870190034807, of 11/11/2019, p. 23/58
20/45 [0056] In the case of parallelogram panels, the space previously mentioned is preferably provided on the short sides.

[0064] In figures 1 to 7, a modality of a panel 1 according to the invention is shown, which is realized as a floor panel, in which all the first five aspects of the invention are applied.
[0065] In the example shown, panel 1 is made as a rectangular parallelogram strip and thus comprises a first pair of opposite edges 2-3, which in this case form the long sides of panel 1, and a second pair of opposite edges 4- 5, which form the short sides of panel 1.
[0066] As is shown in more detail in figures 2 and 3, both pairs of opposite margins 2-3 and 4-5 comprise coupling parts 6-7, 8-9, respectively, which allow mutually coupling a plurality of such panels 1 to each other.
Petition 870190034807, of 11/11/2019, p. 30/58
27/45 [0067] As specifically shown in Figures 4 and 5, the coupling parts 6-7 in the first pair of opposite edges 2-3 are configured so that two of these panels can be coupled together on these edges 2-3 in a form of locking by means of a rotating movement. Here, the coupling parts 6-7 form a first locking system that performs a locking in the plane of the panels 1 and perpendicularly to said margins 23, thus, in this case in the horizontal direction, as well as forming a second locking system, which performs a lock perpendicular to the plane of panels 1, in this case, thus, in the vertical direction. For this purpose, the coupling parts 6-7 are created as a tongue 10 and a groove 11, which provide the vertical lock and comprise parts of the lock 12-13, which, in the coupled condition, prevent alternating away from the tongue and the slot.
[0068] Here, it is preferred that, as indicated, the groove 11 is limited by a lower nozzle 14 and an upper nozzle 15, and that the latch parts 12 and 13 are executed in the form of cooperative projections on the lower side of the tongue 10 and the upper side of the lower nozzle 14, respectively. Cooperation is carried out by means of locking surfaces 16 and 17 provided for this purpose. As also shown, it is also preferred that the lower nozzle 14 extends laterally upwards beyond the distal end of the upper nozzle 15, more particularly so that the surface lock 17 is located completely in the part of the lower nozzle 14 which is located beyond the nozzle higher than 15.
[0069] As schematically represented in figures 6 and 7, the coupling parts 8-9 in the second pair of opposite margins 4-5 are configured so that two of these panels 1 can be coupled to each other by means of a downward movement from one panel to another. This downward movement will be discussed
Petition 870190034807, of 11/11/2019, p. 31/58
28/45 with more details below.
[0070] As is clearly visible in figure 7, the coupling parts 8-9 here also form a first locking system, which performs a locking in the plane of panels 1 and perpendicular to said margins 4-5, thus, in the case in horizontal direction, as well as a second locking system, which locks perpendicularly to the plane of panels 1, in this case, then, the vertical direction.
[0071] The first locking system is substantially formed by a lower hook-shaped part 18 located on margin 5, as well as a lower hook-shaped part 19 located on opposite side 4, whose hook-shaped parts can be engaged one after the other by said downward movement. The lower hook-shaped part 18 consists of a nozzle 20, which extends laterally from the bottom edge of the panel 1 and which is provided with a locking element directed upwards 21 with a locking surface 22, in which the shaped part top hook 19 consists of a nozzle 23, which extends laterally from the top edge of panel 1 and which is provided with a locking element directed downwards 24 with a surface lock 25.
[0072] The second margin lock system on the short sides is formed by the lock parts 26-27, which are located close to the proximal end 28 of the lower hook-shaped part 18 and the distal end 29 of the hook-shaped part higher than 19, respectively. The lock parts 26-27 consist of projections that engage one behind the other, which define the lock surfaces 30-31. It is observed that the coupling parts 8-9 can also mainly be considered a tongue and groove coupling, in which the latch part 27 functions as a tongue, in which the groove in this tongue is sealed, is defined by the latch part 26 working
Petition 870190034807, of 11/11/2019, p. 32/58
29/45 as the upper nozzle, and the first hook-shaped part 18 functioning as the upper nozzle.
[0073] It is observed that the space between the vertically active lock part 26 and the horizontally active lock element 21, which is also indicated by the opening H, functions as a female part 32, in which the lock element 24 is made as a male part 33, which fits into the female part 32.
[0074] Panel 1 is substantially formed on the basis of soft polyvinyl chloride (PVC). More specifically, it comprises a substrate which is made on the basis of soft PVC, the substrate of which is indicated by reference 34 in figures 2 through 13. In these figures, this substrate is schematically described as a single layer. In reality, this can be a single layer as well as several layers, which should not consist of PVC. Generally, an upper layer 35 is provided on the substrate, which in figures 2 to 13 is also represented by a single layer, however, in reality it can also consist of several layers, which will still become clear from the description in figure 14. A top layer 35 is at least intended to provide a decorative top side 36 on panel 1, preferably in the form of a printed decoration and, at least in the case of a floor panel, providing a wear resistant surface offering.
[0075] As indicated in figure 7, the panels have a total thickness T. The thickness T preferably has a value between 3 and 10 mm. In particular in a practical modality, this value will be between 4 and 7 mm.
[0076] It is noted that the previously mentioned coupling parts, 6-7 as well as 8-9, as shown, are preferably formed entirely of the material of the current panel 1, more particularly of the material substrate. As a result
Petition 870190034807, of 11/11/2019, p. 33/58
30/45 of this, the coupling parts also consist of soft PVC. It is observed that the coupling parts 6-7 and 8-9 are preferably also formed by means of mechanical treatment, more particularly milling treatments. The grinding techniques that make it possible to supply the coupling parts at the edges of the panels are known, among others, from WO 97/47834. By selecting the appropriate cutters and adjusting them appropriately, then the appropriate highlighted parts, for example, as shown in the figures, can be performed.
[0077] Preferably, the whole is designed in such a way that, exerting a relatively low force, preferably manually, at least one of said hook-shaped parts 18-19 can be curved from the plane of panel 1, and preferably even both can be curves of the plane of panel 1. By this bending, it is understood that such a hook-shaped part may adopt an inclined position with respect to the rest of such panel 1, in which this may refer to an inclination in such a shaped part. hook, for example, in its mouthpiece, as well as at an inclination in the panel itself, close to the hook-shaped part, so that the hook-shaped part is placed at an angle with respect to the panel itself, or to a combination both. This bending is achieved, among others, due to the flexibility of said soft PVC.
[0078] More particularly, it is preferred that at least one of said hook-shaped parts 18-19, with respect to the plane of the panel in question, can be inclined out of this plane, so that the locking element belonging to 21- 24 can carry out a movement, more particularly a tilting movement, which makes it easier to couple the panels. Such an inclination allows for a light coupling of such panels by means of a base element 37, according to a technical installation that will still be explained in particular.
Petition 870190034807, of 11/11/2019, p. 34/58
31/45 [0079] In figures 8 and 9, it is schematically represented how panels 1 can be installed. To explain the method, a number of panels 1, in order to further differentiate, are indicated by references 1A, 1B, 1C. The panels 1 are placed in a row by row and coupled together. To obtain the coupling of margins 2-3 as well as 4-5, the method comprises at least the following steps:
- installing a first panel 1A directed to form part of the first row of panels;
- coupling a second panel 1B to said first panel 1A, on such first edges 2-3, in which this second panel 1B is directed to form part of the second successive row in said first row of panels;
- coupling in the second row a third panel 1C to said second panel 1B as to the first panel 1A, in which the third panel 1C is coupled to the first panel 1A by means of a rotating movement, in which the third panel 1C, from a rotated position upward, it is brought substantially on the same plane as the first and second panels, in which, as a result of this movement and the downward movement created on it, the hook-shaped parts 18-19 engage each other between the third and the second panel.
[0080] Of course, normally, between installing the first panel 1A and attaching the second panel 1B to it, all the first panels of the row in which the first panel 1A is located, are installed. The coupling of the second panel 1B to the first panel 1A, of course, is also carried out by connecting panel 1B at its margin 2, by means of a rotating movement as shown in figure 4, to margin 3 of the first panel 1A and other possible panels in the row panel 1A.
[0081] When connecting panel 1C to panel 1A, still a movement
Petition 870190034807, of 11/11/2019, p. 35/58
32/45 rotary, as in figure 4, is applied. Here, a downward movement M is carried out on the short edges 4-5, in which the coupling parts 8 and 9 are engaged with each other.
[0082] By this downward movement M, in a very broad sense, each form of movement is directed in that, in a cross section as seen in figures 6 and 7, a panel is left down from a higher position with respect to the other. This movement M should not necessarily be a rectilinear movement, and during this movement, temporary deformations in the panels and more particularly in the hook-shaped parts 18 and 19 can occur. [0083] Theoretically, a downward movement M, which, seen in the cross section, is straight or almost straight, can be used to engage a panel 1C and a panel 1B, which means that the right panel in figure 6, seen in cross-section, it is simply pressed down in the position of figure 7. It is clear that here the local deformations effectively small will occur, as the lock parts 26 and 27 must be pressed one after the other by means of an instantaneous effect. Here, the instantaneous effect is obtained by the elasticity of the soft PVC and the tilting actions on the component parts and compressions in the material that occur as a result of this.
[0084] Practically seen, however, the use must be made of a technique described in more detail below, by which the installation of panels 1 is facilitated. Namely, so that, when joining the panels using the previously mentioned theoretical form, the hook-shaped parts 18-19 are difficult to press fixedly together, since the flexibility of soft PVC is very low. Press the hook-shaped parts 18-19 fixedly together in accordance with the aforementioned theoretical form, in the represented profile it will normally be carried out only by exerting a force with a tool on the upper side of the panel to be joined on the other, in the respective margin of it, by example, for
Petition 870190034807, of 11/11/2019, p. 36/58
33/45 middle of a hammer or the like.
[0085] According to a practical technique of the invention, a base element 37 is applied when interconnecting panels 1C and 1B, so that during the joining the inclination is created in one or both hook-shaped parts 18-19 , as a result of which the male part 33 fits more easily into the female part 32. Here, the base element 37 is provided below the edge 5 of the panel 1B, more particularly it is pushed under, so that the hooked part 18 is freely hanging at a distance above the subsurface, more particularly as can be seen in figures 12 and 13. By subsequently coupling panel 1C during deviation to panel 1B, different movement mechanisms can be created, depending on the location where the pressure it is exercised in panel 1C, whose mechanisms, however, always lead to a slight union of the margins, without having to exert much force for this purpose. Thus, pressing can occur by exerting a force F on panel 1C with a finger.
[0086] According to figure 12, the force F is exerted on the upper part of the hook-shaped part 19, with the result that this hook-shaped part 19 also tilts a little or nothing and only the shaped part hook 18 tilts downwards, in which the opening H shown in figure 11 enlarges a little and the male part 33 will fit better into the female part 32.
[0087] However, even better, as shown in figure 13, a force F is exerted on panel 1C at a distance that is slightly remote from margin 4, with the result that the entire hook-shaped part 19 goes into the inclined position. upwards with respect to the rest of the panel. As a result of this, the locking element 24 performs a tilting movement, whereby it fits more easily through said opening H, after removing the pressure on the panel
Petition 870190034807, of 11/11/2019, p. 37/58
34/45
1C, this part of the latch 24 tilts back to its normal position, in which the latch part 27 sits below the latch part 26. Of course, here, too, an inclination in the hook-shaped part 18 will also occur, as a As a result of this, analogous as discussed by means of figure 12, the union is also facilitated once again.
[0088] During the joining according to figure 13, an instantaneous effect may or may not occur, depending on the design of the coupling parts and the inclination performed on the hook-shaped parts 18 and 19 performed during the joining. It is clear that by an inclination here, the inclination in a hook-shaped part 18 or 19 must be understood, thus the nozzle 20 and / or 23 is inclined, as well as an inclination of such part in its entirety, in which the zone of inclination is not located at the nozzle 20 and / or 23, but at a greater distance from the respective margin on the respective panel. The inclination can also consist of a combination of these two possibilities.
[0089] In the most preferred embodiment, the coupling parts 89 are made in such a way that, making an inclination as in figure 13, however, in a more pronounced form, the male part 33 can be inserted in the female part 32 without any instantaneous effect , this by means of the tilt movement discussed above. By means of a pronounced inclination, the male part 33 can effectively be inserted freely into opening H, after that, by its rear inclination, it is fitted with the part of the latch 27 below the part of the latch 26 without any instantaneous effect. Such pronounced inclination is shown in figure 14, in which said opening is enlarged so that the locking element 24 can easily move downwards between the locking element 21 and the locking part 26, whether any fixing effect or not, until the lock surface 31 slides below the lock surface 30 and the lock is obtained. It is observed that the technique applied here
Petition 870190034807, of 11/11/2019, p. 38/58
35/45 results in the coupling that is no longer operative like the coupling called a push, but still provides a local rotary movement, in which certain parts perform the tilting movement to each other by deforming the respective margin zones.
[0090] An important advantage of the practical methods discussed above is the movement of the lock parts 26 and 27 one behind the other, the panel 1C, when left down, should not make a short switching movement back and forth when along the already coupled margin 2, or this switching movement is greatly reduced. In a number of systems called angled or bent pushing, such a forward and backward switching motion actually poses a problem, as the new panel, which is already attached to the longitudinal margins, generally does not pull correctly against the previous panel in the same row. By this technique described above, in which a tilting movement occurs at the margins 4-5 to be coupled, the entire panel, to provide the lock parts 26 and 27 one behind the other, must not carry out a forward and backward movement. in the longitudinal direction, or this forward and backward displacement is considerably reduced, by the said problem is excluded, reduced, respectively.
[0091] Finally, in figure 15 the particular modality of a panel according to the invention is shown, with the particularity that on the substrate 34 a reinforcement layer 38 is provided, preferably of fiberglass, more particularly a mesh or wool of fiberglass. An important preferred feature here is that at least one of the nozzles 20, 23, respectively, and preferably both, comprise a part G1, G2, respectively, which are free of the reinforcement layer 38, so that a good bend in the respective nozzle is maintained.
[0092] As an example, figure 15, away from the reinforcement layer
Petition 870190034807, of 11/11/2019, p. 39/58
36/45
38, also represents a practical construction, which is composed as follows:
- the substrate, which consists of two basic layers 3940, with the reinforcement layer 38 embedded between them;
the upper layer 35, which is composed of a film 41 printed with a theme, a transparent wear layer layer 42 and one or more transparent layers of varnish 43;
- on the underside, a rear layer 44.
[0093] Basic layers 39 and 40 consist of PVC, possibly recycled PVC, where reinforcement layer 38 consists of a fiberglass mesh. The printed film 41 consists of a printed PVC film. The transparent wear layer 42 consists of a thin vinyl layer, in which wear-resistant particles, preferably ceramic particles, such as corundum and the like, are incorporated. The layers of varnish 43 offer added protection and are preferably formed of two layers of transparent polyurethane varnish, in which optionally the wear-resistant particles have also been incorporated.
[0094] The thickness of the layers may vary from manufacturer to manufacturer. In figure 15, they are described only schematically. In a practical embodiment, they can have, for example, the following thicknesses: 1 mm for the back layer 44; 2.5 mm for the lower base layer 37; 0.3 mm for the fiberglass mesh; 1.5 mm for the upper basic layer 38; 0.1 mm for the printed film 39; 0.5 mm for wear layer 40; and 0.1 mm for all varnish layers 41.
[0095] Still, the impressions can be provided on the surface, in the form of a relief, which, for example, imitates a real structure of the surface, for example, of wood or similar. This relief can be accomplished in the registration with the door.
Petition 870190034807, of 11/11/2019, p. 40/58
37/45 [0096] Still, it is generally observed that preferably also one or more of the following characteristics are applied:
- the part of the lock 27 is placed slightly towards the internal part, so that it is located completely below the upper side of its own panel;
- the parts of the lock 26-27 forming the second lock system are made in the form of projections, regulations, respectively.
[0097] The present invention is not restricted to the modalities described by way of example and represented in the figures, however, such a panel, such a cover and such a method for installing the panels can be carried out according to the various variants, without departing from the scope of the invention.
[0098] For example, a support part 45 can be provided in the base element 37, with which this base element 37 can be slid against the front edge of the panel 1B, to obtain that this base element is located perpendicular to the longitudinal direction of the panels . At the front edge 46 possibly a means, such as an inclined part, can be provided, as a result of which the base element can be easily slid under the already installed panel 1B. It is observed that the base element 37 preferably has such a length that it reaches even below panel 1A.
[0099] The panel described below by means of figures 16 to 28, as well as methods to install and manufacture it, refer to the seventh to the thirteenth aspect of the invention.
[00100] In the example shown, panel 1 is rectangular and parallelogram and comprises a pair of margins 2-3, which form the long sides of panel 1, as well as a pair of margins 4-5, which form short sides. In addition, the panel shown 1 comprises a substrate 34, which consists of a soft PVC-based material.
Petition 870190034807, of 11/11/2019, p. 41/58
38/45
In addition, panel 1 is completely flexible.
[00101] As can be seen in figures 17 and 18, in each pair of margins 2-3 and 4-5, the coupling parts 6-7, 8-9, respectively, are present, which are formed on the substrate 34 and which, in the coupled condition of two of these panels 1, make a vertical lock as well as in the horizontal direction. Here, these coupling parts 6-7 and 89 on both pairs of margins 2-3 and 4-5 are configured so that two of these panels can be coupled together by means of a rotating movement, as shown in figure 19 .
[00102] In this case, the coupling parts 6-7 and 8-9 consist of both pairs of edges of a tongue 10 and a groove 11, as well as parts of the lock 12-13, which, in the coupled condition, prevent the spacing of the tongue 10 and the groove 11. The groove 11, respectively, is surrounded by a lower nozzle 14 and an upper nozzle 15, wherein the lower nozzle 14 extends laterally upwards beyond the distal end 47 of the upper nozzle 15. The parts of the lock 12-13 define the lock surfaces 16-17. It is observed that in the example shown, the profiles of the tongue and groove in both pairs of margins 2-3 and 4-5 are identical to each other, which, of course, is not absolutely required. For the sake of simplicity, in the embodiment of figures 16 to 21 thus the same references 10 to 17 are applied to the specific description of the coupling parts 6-7 as well as the coupling parts 8-9.
[00103] The locking surfaces 16-17 are located at least partially, and, as shown, completely in the part of the lower nozzle that is located beyond the distal end of the upper nozzle.
[00104] Figure 20 represents that in the coupled condition of two of these panels 1, a space 48 is present below the tongue 10, said space extending continuously below the tongue 10 as
Petition 870190034807, of 11/11/2019, p. 42/58
39/45 from the tip of the tongue 10 to a location 50, which is located beyond the distal end 47 of the upper nozzle 15.
[00105] Said space 48 extends below the tongue 10 over a length L1, measured parallel to the plane of the panel, which preferably is at least 1.5 times, and even better at least 2 times, the distance L2 from the tip 49 of the tongue 10 to the distal end 47 of the upper nozzle 15, which performs a slight insertion of the tongue into the groove and also contributes that two of these panels can be alternated along their margins mutually.
[00106] As shown, the tongue 10 is preferably connected with the remainder of panel 1 by means of a narrow part 51. The smallest thickness A of part 52 of the lower nozzle 14, which is located beyond the distal end 47 of the upper nozzle 15, it is preferably less than the smallest thickness B of said narrow part 51. It is further preferred that the tongue 10, in a downward direction, is supported in the groove by means of the locking surfaces 16 and 17 and / or by means of a support point 53 located close to the lock surface 17.
[00107] The support point 53, which also provides support in a downward direction, preferably has a tangent line of contact 54 that forms an inclination with the horizontal that is less than 30 degrees and even better is less than 10 degrees and even better is zero degrees, as is the case in figure 20.
[00108] The fact that away from the locking surfaces 16 and 17, also a support point 53 is present, ensures that the tongue 10 cannot move up and down in the groove and that no height difference can occur between the coupled panels.
[00109] Figure 20 also shows that the contact part 55, which is located on the lower face of the upper nozzle 15, preferably forms a slight downward inclination in the next direction, which allows
Petition 870190034807, of 11/11/2019, p. 43/58
40/45 work with a grinding cutter slightly tilted downwards, which will be explained further in the description in figure 28.
[00110] As shown, the tongue 10 is preferably chamfered or rounded on the upper side, close to the tip 49. The chamfered and / or rounded part 56 preferably extends over the distance L3, which is at least 1/4 and even better by minus 1/3 of the L2 length, as measured in a direction parallel to the plane of the panels. Also distally from the contact part 55, as shown, preferably a chamfered and / or rounded part 57 is present on the lower face of the upper nozzle 15, such as on the distance L4, which is at least 1/5 and even better 1/4 of the said L2 distance.
[00111] The average thickness L5 of the tongue part 10 located in the coupled condition below the contact part 55, is preferably less than 1.5 mm to maintain the maximum thicknesses of the material for the upper nozzle 15 and the lower nozzle 14 of this. shape, which is of importance with vinyl panels, which are mostly relatively thin. Preferably, the tongue 10 is relatively long with respect to its thickness. More particularly, it is preferred that the distance L2 is greater than 1.2 times and even better is greater than 1.3 times the previously mentioned thickness L5, by which a positive lock in the direction of height can be guaranteed.
[00112] The lower nozzle 14 is preferably relatively stable with respect to the groove structure. More particularly, it is preferred that the distance A, which refers to the thinnest part of the lower nozzle 14, is at least 0.7 times the distance L6. Here, the distance L6 is the average thickness of the upper nozzle 15 at the location of the contact part 55.
[00113] As can be seen in figure 21, the tongue and groove are made in such a way that, when two of these panels 1 are presented a
Petition 870190034807, of 11/11/2019, p. 44/58
41/45 to the other in a plane-parallel shape on the margins in question, the tongue 10 sits at least with its tip already at least partially below the nozzle 15 surrounding the upper side of the groove 11, without any inclination being already necessary. This offers the advantage that the tongue 10, during the installation of the panels 1, almost always automatically ends up in the groove. Furthermore, it is preferred that, due to the elasticity and bending of the materials, from which these panels are made, two of these panels can also be forced into each other by means of an instantaneous movement. This can be accomplished, for example, by pushing two of these panels 1 from a mutual position, as in figure 21, towards each other. This can also be accomplished by starting from a position in which both panels 1 are located completely close to each other, and alternating them from this position towards each other. The rounded parts 58 and 59 shown in figure 21 then cooperate with each other and provide the tongue 10 which is then alternated and subsequently on the lock part 13.
[00114] It is observed that all the partial characteristics described here above, according to the unrepresented variants of the invention, must not be combined in the same modality and must also not be present in both margins. Each of the features described above, indices and the like can occur as in combination with one of the independent aspects of the invention.
[00115] Figures 22 to 25 represent how panels 1 can be installed using an angle-angle technique, which means that the panels are installed using a rotation technique on the 2-3 and 4-5 margins. Here, for clarity, the panels are indicated by the different references 1D, 1E and 1F.
[00116] Figure 22 shows a situation that these 1D panels in the
Petition 870190034807, of 11/11/2019, p. 45/58
42/45 the same row are already attached to each other and, in a second row, a panel 1E is already attached to it. The new panel 1F to be coupled to the panel 1E by means of a rotating movement W1, in which this panel 1F with respect to the nearest margin of the panels 1D is located slightly alternated on the distance D1. The rotating movement W1 is a movement similar to that shown in figure 19.
[00117] After that, both panels 1E and 1F are simultaneously turned slightly upward, whose rotary movement is indicated by W2 in figure 24. Subsequently, panel 1F is alternated with its margin 4 along the margin 5 of panel 1E, by means of a switching motion S, until the condition of figure 25 is achieved. Due to the presence of said space 48, it is obtained that the tongue 10 during this switching movement S cannot be caught in the most rigid part of the groove, in particular the part located below the upper nozzle. In the case of synthetic material, and in particular in the case of soft PVC, otherwise a very fast tightening effect would appear, which makes installation difficult, or even impossible. [00118] As a result of the previously mentioned switching motion S, panels 1F and 1D are in a position on their cooperation margins, which is analogous to that in figure 19. Of course, panel 1F can be brought into its position completely installed by turning panels 1E and 1F then from the position of figure 25 simultaneously downwards in the flat condition, such by means of the rotating movement W3.
[00119] By applying a tongue and groove that allows a mutual presentation as illustrated in figure 21, it is also obtained that with the alternation represented in figure 24 the tongue in margin 6 automatically searches for a path in the grooves 11 of margins 7 of panels 1D , even when panels 1E and 1F are raised slightly.
Petition 870190034807, of 11/11/2019, p. 46/58
43/45 [00120] Thus, it is clear that the use of space 48 is of particular importance on the short sides, in which a configuration that allows a mutual positioning as in figure 21 is particularly useful on the long sides.
[00121] Figure 26 represents a technique, which can replace the steps in figures 22 and 23. Here, panel 1E is first slightly rotated upwards and in this position panel 1F is presented with its margin 4 to margin 5 of panel 1E and is rotated, after again a condition as in figure 24 is obtained.
[00122] It is observed that it is preferred that a panel 1 according to the invention is manually flexible at least in one direction so that it can be inserted, in the margins extending across this direction, with a tongue over the lower nozzle of a anterior panel in the groove of this anterior panel, until the upper margins touch, and without inclination of the lower nozzle of the anterior panel, in which the respective panel, on the margin located opposite the margin having said tongue, is inclined down to the surface base. This allows such a panel to be easily inserted with the tongue in question into the groove of an anterior panel. As the panel on the opposite margin can be tilted upwards from the base surface, or possibly, under the influence of its own weight, it tilts down from the base surface, the panel can be easily aligned in said direction with respect to the panels already installed. In the case of parallelogram panels, said direction is preferably the longitudinal direction of the panel.
[00123] A practical application, in which said feature shows its advantages, is represented in figure 27. In figure 27, a panel 1F is coupled to panel 1E, analogous to figure 22, however, panel 1F is then brought in or lied in an inclined condition. In this way, a tongue from margin 4 can be inserted into the respective slot in panel 1E, analogous to figure 19, in which the corner 60
Petition 870190034807, of 11/11/2019, p. 47/58
44/45 remains on or near the base surface and then the panel 1F can be positioned with the corner 60 close to the margin 3 of the panel 1D, an alignment in the longitudinal direction is obtained, which facilitates the realization of the coupling on the short sides.
[00124] According to a deviation variant of the invention, it also refers to panels that are made of synthetic material and in particular with soft PVC base, in which, as previously mentioned, the use is made of a space below the tongue however, in which it is not necessary for the coupling parts to be present on the other pair of sides, or where these coupling parts provide exclusively a vertical lock or exclusively a horizontal lock. Such space also in such an application still offers certain advantages, among others, of an easy insertion of the tongue in the groove.
[00125] Figure 28 represents that a groove 11 can be made, among others, by means of a rotary cutting tool 61, such as a grinding cutter, which is inclined with respect to the plane of the panel. This makes it possible to give the cutting parts 62 of the cutting tool 61 a greater thickness than when using a cutting tool 61 by rotating in the plane of the panel. This is of particular importance with thin panels, for example, less than 5 mm thick, in order to give the cutting parts 62 a correct thickness, the thickness D2 of which is at least 1.4 mm. Towards the bottom face of the panels, the cutting parts 62 can remove more material, as here, so the space 48 must be made. It is observed that the panel here is represented vertically, however, in a grinding process, the panel is most often lying upside down on a support surface.
[00126] Finally, it is observed that the panels above are substantially described as the floor panels. Certain terminology refers to the position taken by a panel when applied
Petition 870190034807, of 11/11/2019, p. 48/58
45/45 as the floor. However, it is clear that with an application on the wall or ceiling panels, this terminology must be interpreted in an adapted way. The lower hook-shaped part should then be seen as the hook-shaped part located against the rear. A locking element directed upwards should then be seen as a locking element extending towards the rear to the decorative side. A downward movement then forms the movement through a panel that is moved with its back towards the plane on which the cover is to be made.
[00127] Also, it is observed again that, where soft PVC is mentioned, according to an alternative referenced in the invention, also other synthetic materials can be applied, which have a similar flexibility to LVT or soft vinyl tiles. It is also clear that the substrates targeted in the application can consist of a plurality of layers, among other materials, such as, for example, reinforcement layer.
[00128] Still, it is clear that when using as floor panels, these panels can be installed floating, which, however, does not exclude that, according to an alternative, they can also be glued to the base surface.
