EP3907346B1 - Multi-profile panel - Google Patents

Description

The invention relates to a multi-profile panel of rectangular shape, with which laying in different laying patterns, including herringbone, is possible using only a single type of panel.

The state of the art is that all four edges of a panel are grooved or the longitudinal edge is provided with standard tongue and groove and both transverse edges are grooved. Two different types of panels are created for laying by hammering in external springs. This allows easy storage, but there are very high costs when laying. In particular, herringbone patterns can often only be created by subsequently changing the profiles and are very difficult to install.

In the DE 698 17 781 D1 shows a herringbone pattern installation with only one type of panel, the panel being provided with opposing standard tongue profiles on the long edge. At the edges of the tongue profile, the tongues have been removed at certain intervals and replaced by grooves, so that a mirror-inverted shape is achieved. A standard groove profile is provided on both transverse edges. The manufacture of this panel is relatively difficult in terms of production technology, with productivity being rather low since a high feed rate is not possible due to the complex structure.

From the U.S. 2,187,672 A It is also known to glue three formatted layers together in such a way that a groove is formed on half the longitudinal edge and a tongue is formed on the second half. The longitudinal edges are mirror images of the same, the transverse edges have a standard tongue and groove profile. Here too, manufacture of the panel is relatively difficult in terms of production technology, and productivity is rather low. Laying in a herringbone pattern or bonded laying with one type of panel is possible here.

From the EP 3 128 102 A1 a panel is known in which on the longitudinal edges a continuous standard groove profile and on the opposite edge to the There is a standard tongue profile interrupted at the ends of the panel. At the breaks, the tongue profile was replaced by a groove profile. A standard tongue profile is provided on both transverse edges. Laying a herringbone pattern with one panel is possible here. But here, too, manufacture of the panel is relatively difficult in terms of production technology, and productivity is rather low.

In the U.S. 1,787,027 A a standard tongue and groove connection is described. The groove profile is provided on one longitudinal and transverse edge, the tongue profile on the opposite longitudinal and transverse edge. Herringbone laying is only possible with two different types of panels, with the production of two different types of panels having the disadvantage of double storage, the risk of confusing the panels, increased assembly effort and higher costs.

In the DE 202 08 058 U1 it is also possible to create a herringbone pattern. However, different right and left panels are required to create the laying pattern. Here, too, there is the disadvantage of double storage, the risk of confusing the panels, the increased assembly effort and higher costs.

WO 2005/098163 A1 discloses a panel according to the preamble of claim 1.

It is therefore an object of this invention to provide an easy-to-manufacture panel with corresponding profiles, with which it is possible to lay different laying patterns, including herringbone, with just one panel. According to the invention, this object is achieved by the features of the independent patent claims. Advantageous configurations are the subject matter of the dependent claims.

1. 1. Ein Nut-Feder-Profil, aufweisend eine durchgängige Nut mit einer Nutbreite und einer Nuttiefe, und eine durchgängige Feder mit unterschiedlichen Federdicken und Federlängen.
2. 2. Ein Nut-Profil, aufweisend eine durchgängige Nut mit unterschiedlichen Nutbreiten und Nuttiefen.
3. 3. Ein Nut-Doppelfeder-Profil, aufweisend eine durchgängige Nut mit einer Nutbreite und unterschiedlichen Nuttiefen, und eine durchgängige Doppelfeder mit unterschiedlichen Federdicken und Federlängen.

Proposed is a panel having a rectangular shape with the first and third sides facing each other and the second and fourth sides facing each other, each of the four sides of the panel having a profile of the following three profiles:

1. 1. A tongue and groove profile, having a continuous groove with a groove width and a groove depth, and a continuous tongue with different tongue thicknesses and tongue lengths.
2. 2. A groove profile, having a continuous groove with different groove widths and groove depths.
3. 3. A groove/double tongue profile, having a continuous groove with a groove width and different groove depths, and a continuous double tongue with different tongue thicknesses and tongue lengths.

In addition, two opposite sides have the same profile.

Due to the three different profiles on a single panel, each of which can be brought into engagement with one another, different laying patterns can be laid at a 90-degree angle with just one type of panel without any additional tools. Herringbone patterns are also easy to lay. The tongue and groove profile has a dual function, that of a groove or that of a tongue, since it fits into both the groove profile and the tongue and groove profile. All three profiles have a vertical division into three and are created by horizontal profiling.

The groove widths of the grooves of the three profiles are formed in such a way that corresponding tongues of a tongue-and-groove profile to be connected thereto or of a tongue-and-groove profile to be connected thereto can be brought into positive engagement with the top and/or bottom of the panel. In this way, they connect the profiles and the panels are flush with their surfaces and front edges and cannot be displaced. The profiles are locked vertically and only pushed into each other horizontally.

Furthermore, it is provided that the groove width of the groove of the groove profile corresponds to the total tongue thickness of the double tongue profile. In this way, the groove profile can be connected to the groove-double-tongue profile, with the grooves and tongues being connected to one another on the upper side and on the underside of the panel.

Furthermore, it is provided that the first side of the panel has a tongue and groove profile, the third side has a double tongue and groove profile, and the second side and the fourth side each have a groove profile. So a laying at a 90 degree angle without additional tools or additional adjustment of the profiles, also in the herringbone pattern.

In one embodiment it is provided that a lower groove cheek of the groove profile of the second and fourth side is removed in such a way that the groove ends at or behind a front edge of the respective sides. In this way, a linear laying can be realized.

In an alternative embodiment it is provided that the first side of the panel has a tongue and groove profile, the third side has a tongue and groove profile, and the second side and the fourth side each have a tongue and groove profile. This means that it can be laid at a 90-degree angle without any additional tools or additional adjustment of the profiles, even in a herringbone pattern.

In an alternative embodiment it is provided that the first side of the panel has a tongue and groove profile, the third side has a tongue and groove profile, the second side and the fourth side each have a tongue and groove profile. This means that it can be laid at a 90-degree angle without any additional tools or additional adjustment of the profiles, even in a herringbone pattern.

Laying patterns using several similar panels are also proposed.

In the following descriptions of the figures, the same elements or functions are provided with the same reference symbols.

The aim of the invention described below is to enable different laying patterns, including herringbone, with just a single panel, primarily without additional aids such as springs to be driven in, etc., as is otherwise known from the prior art. This is achieved by providing a multi-profile panel, i.e. a single panel A-C with three different profiles 1-3 described in detail below. These can be arranged in a suitable combination on panel A-C, with three variants being described.

Panels A-C are always rectangular, i.e. each with two parallel sides (first and third side are parallel, and second and fourth side are parallel). The term rectangular shape also includes a square shape as a special shape of the rectangle.

In addition, each panel A-C has a front edge 101, which extends from its top O perpendicularly in the direction of its underside U to the beginning of the profile 1-3. This front edge 101 serves as a stop edge when connecting two panels AC to one another and forms the visible joint between the panels AC, which is closed towards the upper side O of the panel AC.

The basic principle and the individual profiles 1-3 are first described using panel A. In figure 1 A perspective view of a panel A is shown for illustrative purposes. figure 2 shows a plan view of panel A. In both figures it can be seen that the two opposite short sides (sides two and four) of the rectangle have the same profile, namely a groove profile 2, and the other two sides (sides one and three) have two other different profiles, namely one each Tongue and groove profile 1 and a tongue and groove profile 3.

The three different profiles 1-3 used are in Figures 3 to 5 shown. figure 3 shows a tongue and groove profile 1, figure 4 shows a tongue and groove profile 3 and figure 5 shows a groove profile 2.

This in figure 3 The tongue and groove profile 1 shown has a groove 102 adjoining the front edge 101 with a groove depth n4 and a groove width N5. This groove 102 serves to accommodate the upper tongue 105 of the tongue and groove profile 3 when profiles 1 and 3 are joined together, as in figure 6 shown. Adjoining the groove 102 is a tongue 103 with a total tongue thickness F2 and a total tongue length f1. The nose of the spring 103 protruding beyond the (imaginary line along) the front edge 101 has a spring thickness F3 and a spring length f2. The top of the spring lug 103 (from the rear end of the groove 102 to the front end of the spring lug 103) has a spring length f5. This tongue 103 serves to fit into the groove 106 of the tongue and groove profile 3 when profiles 1 and 3 are joined together as in figure 6 shown. The spring 103 jumps back on its underside in a thickness F2-F3 up to the front edge 101. This serves to accommodate the bottom tongue 107 of tongue and groove profile 3 when profiles 1 and 3 are joined together as in figure 6 shown. Then it springs back further behind the front edge 101 up to the spring length f1. These two areas serve as tongue 104 of tongue and groove profile 1. The lower edge of tongue 104 serves to accommodate a lower groove cheek 111 of groove profile 2 when profiles 1 and 2 are connected to one another, as in figure 8 shown.

This in figure 4 The tongue-and-groove profile 3 shown has an upper tongue 105 adjoining the front edge 101 and protruding therefrom with a tongue thickness F5 and a tongue length f3, ie the tongue 105 projects beyond the front edge 101 by a tongue length f3. Adjoining this is a groove 106 with a groove width N4, which is formed in such a way that it can accommodate the tongue 103 of the tongue and groove profile 1, as shown in FIG figure 6 shown. Adjoining the groove 106 is a lower tongue 107 provided which protrudes at most up to the (imaginary line along the) front edge 101 and has a spring thickness F4 and a spring length f4. The total tongue thickness F1 of the tongue and groove profile 3 is made up of the tongue thicknesses F4 and F5 of the tongues 105 and 107 and the groove width N4, which corresponds at least to the tongue thickness F3 of the tongue element 103 of the profile 1. The end of the underside of the tongue 107 ends with the end of the groove 106, i.e. the imaginary line along the groove 106, and serves to rest on the lower groove cheek 111 of the groove profile 2 when profiles 2 and 3 are connected to each other, as in figure 7 shown. In this variant, the tongue and groove profile 3 acts like a single tongue with tongue thickness F1, ie the upper edge of the upper tongue 105 and the lower edge of the lower tongue 107 are each attached to the lower edge or upper edge of the groove 109 with the total groove width N1 of the profile 2 is inserted and connected to it.

This in figure 5 The groove profile 2 shown has a groove 109 adjoining the front edge 101 with a total groove depth n1 and a total groove width N1. The groove 109 consists of three areas, of which the first area connects directly to the front edge 101 and is formed as a fold 110, which serves to block the upper tongue 105 of the tongue and groove profile 3 to the top O of the panel AC, when profiles 2 and 3 are joined together as in figure 7 shown. The second area is an inner groove 108, the upper edge of which ends in the groove depth n2 and the lower edge of which ends in the groove depth n3, i.e. before the imaginary line along the front edge 101. The groove 108 has a groove width N3, which is formed in this way is that the tongue 103 of the tongue and groove profile 1 can be pushed in when profiles 2 and 1 are connected to one another, as in figure 8 shown. Beginning at the groove depth n3, adjoining the groove 108 is a third area, which has a groove width of N2-N3. Adjacent to this is the upper edge of a lower groove cheek 111 of the groove profile 2. The groove cheek 111 protrudes to a groove depth n1 (measured from the end of the inner groove 108), which is greater than the groove depth n2 (which ends at the end face). This means that the lower groove cheek 111 of the groove profile 2 projects beyond the end edge 101 . The lower groove width from the upper edge of the groove 108 to the upper edge of the groove cheek 111 is N2. As already mentioned, the lower groove cheek 111 of the groove profile 2 serves as a support for the underside of the tongue 107 of profile 3, but also to be pushed under the lower edge of the tongue 104 of profile 1, so that the groove cheek 111 can be locked in the direction Top O of panel AC done.

In figure 9 an example of laying several panels A at a 90 degree angle to each other is shown. This example shows a herringbone pattern that can be laid with several panels A without additional tools such as additional tongues, additional cut-outs, i.e. post-processing of panels. This means that with the proposed three different profiles on a panel AC, laying such a pattern with only one type of panel A, B or C is possible. Thus, unlike in the prior art, two different panels (left and right panel) with two profiles, more precisely a groove profile lengthwise and crosswise and a tongue profile lengthwise and crosswise, are not required.

In Figures 10-12 comparatively three variants of panels AC are shown, each with different profiles on their sides. figure 10 shows panel A, figure 11 shows panel B and figure 12 shows panel C.

• die erste Seite weist das Nut-Feder-Profil 1 auf,
• die dritte Seite weist das Nut-Doppelfeder-Profil 3 auf,
• die zweite Seite und die vierte Seite weisen jeweils das Nut-Profil 2 auf.

The sides of panel A are formed as follows:

• the first side has the tongue and groove profile 1,
• the third side has the tongue and groove profile 3,
• the second side and the fourth side each have the groove profile 2.

• die erste Seite weist das Nut-Doppelfeder-Profil 3 auf,
• die dritte Seite weist das Nut-Profil 2 auf,
• die zweite Seite und die vierte Seite weisen jeweils das Nut-Feder-Profil 1 auf.

The sides of Panel B are formed as follows:

• the first side has the tongue and groove profile 3,
• the third side has the groove profile 2,
• the second side and the fourth side each have the tongue and groove profile 1.

• die erste Seite weist das Nut-Feder-Profil 1 auf,
• die dritte Seite weist das Nut-Profil 2 auf,
• die zweite Seite und die vierte Seite weisen jeweils das Nut-Doppelfeder-Profil 3 auf.

The sides of panel C are formed as follows:

• the first side has the tongue and groove profile 1,
• the third side has the groove profile 2,
• the second side and the fourth side each have the tongue and groove profile 3 .

The second and fourth sides therefore have the same profile 1, 2 or 3 in each variant. In the case of a rectangular panel AC with two long and two short sides, the second and fourth sides are the short side, ie the transverse profile.

All three profiles 1-3 are divided vertically into three, i.e. tongue and groove profile 1 is divided into three by tongue thicknesses F2 and F3 and groove width N5, groove profile 2 is divided into three by groove widths N1, N2 and N3 and that The tongue and groove profile 3 is divided into three by the groove width N4 and the tongue thicknesses F4 and F5.

Profiles 1-3 are created by horizontal profiling, i.e. unlike glueless laying profiles, which are profiled both horizontally and vertically and at an angle.

With the three variants of the panels A-C, different laying patterns such as herringbone, double herringbone, cube, braid, bond, irregular bond and cassette can be executed. The laying pattern results from laying panels A or B or C at a 90° angle. This means that right and left panels are no longer required. It is also no longer necessary to edit standard profiles in order to realize the laying of such patterns.

In the case of the variant with panel A, it is also possible to lay it linearly as in figure 16 shown, if the groove cheek 111 of the groove profile 2 is cut off in such a way that it is flush with the front edge 101 or is shorter than this (see figure 15 ). The comparison between groove profile 2 and groove profile 2 with the groove side 111 cut off is in Figures 13 and 14 shown, with the in figure 14 The groove profile 2 shown with the groove cheek 111 cut off is also referred to below as profile 4.

In figure 15 two connected panels A with profile 4 are shown, which means that the groove cheeks 111 are cut off on both sides with the groove profile 2. It can be seen here that the front edges 101 abut one another and the two panels A are connected by inserting an external tongue FF. The external tongue FF is essentially T-shaped, so that it can engage in the opposing inner grooves 108 as well as in the folds 110 . The height of the external tongue FF corresponds to the groove width N6, i.e. the distance between the lower edge of the fold 110 and the lower edge of the inner groove 108.

By changing profile 2 to profile 4 without groove side 111, a linear installation can be implemented, as in figure 16 shown. In this way, further laying patterns can be realised.

The proposed multi-profile panel can be used for all common materials, in particular laminate, parquet and PVC, e.g. LVT, in different thicknesses. In addition, all common laying patterns, especially laying at a 90 degree angle, i.e. also herringbone, can be realized without additional tools. Due to the differently arranged profiles 1-3 on a panel AC, the production of the panels AC is easier and the feed rate is high. Duplicate storage is also not necessary and laying is easier and therefore faster.
