EP3907346A1 - Multi-profile panel - Google Patents

Abstract

A panel is proposed having a rectangular shape in which the first and third sides are opposite one another and the second and fourth sides are opposite one another, each of the four sides of the panel having a profile made up of the following three profiles: 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, a groove profile, having a continuous groove with different groove widths and depths, 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.

Description

The invention relates to a multi-profile panel of a 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. By hammering in foreign springs, two different types of panels are created for laying. This enables simple storage, but the installation costs are very high. In particular, herringbone patterns can often only be created by subsequently changing the profiles and are very complex to lay.

In the DE 698 17 781 D1 an installation in a herringbone pattern with only one type of panel is shown, the panel being provided with opposing standard tongue profiles on the longitudinal edge. The tongues on the tongue profile edges were removed at certain intervals and replaced by grooves, so that a mirror-image 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, the 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 created on half the longitudinal edge and a tongue on the second half. The longitudinal edges are mirror-inverted, the transverse edges have a standard tongue and groove profile. Here, too, the production of the panel is relatively difficult in terms of production technology, and productivity is rather low. Laying in a herringbone pattern or laying in a bond with one type of panel is possible here.

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

In the U.S. 1,787,027 A describes a standard tongue and groove connection. 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 mixing up the panels, the increased installation 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 produce the laying pattern. Here, too, there is the disadvantage of double storage, the risk of mixing up the panels, the increased installation effort and higher costs.

It is therefore an object of this invention to provide a panel with corresponding profiles that is easy to manufacture and 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 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.

Außerdem weisen zwei einander gegenüberliegende Seiten dasselbe Profil auf.A panel is proposed having a rectangular shape in which the first and third sides are opposite one another and the second and fourth sides are opposite one another, each of the four sides of the panel having a profile made up 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.

Thanks to the three different profiles on a single panel that can be interlocked, different laying patterns can be laid at a 90-degree angle with just one type of panel without any further aids. Herringbone patterns are also easy to lay. The tongue and groove profile has a double function, that of a tongue or that of a tongue, since it fits into the tongue and groove profile as well as the tongue and groove profile. All three profiles are divided into three vertically and are created by horizontal profiling.

Furthermore, it is provided that 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 or of a double-tongue profile to be connected to the top and / or bottom of the panel form a positive fit are engageable. In this way, they connect the profiles and the panels are flush with one another with their surfaces and front edges. The profiles are locked vertically and only pushed into one another 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. The groove profile can thus be connected to the groove double-spring profile, the grooves and tongues being connected to one another on the top and bottom 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. Laying at a 90-degree angle can therefore be carried out without further aids or additional adaptation of the profiles, even 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 an end edge of the respective sides. In this way, a linear installation can be implemented.

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. Laying at a 90-degree angle can therefore be carried out without further aids or additional adaptation of the profiles, even in the 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, and the second side and the fourth side each have a double tongue and groove profile. Laying at a 90-degree angle can therefore be carried out without further aids or additional adaptation of the profiles, even in the herringbone pattern.

Laying patterns using several panels of the same type are also proposed.

In the following description 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 only a single panel, primarily without further aids such as springs to be hammered, etc., as 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, which are described in detail below. These can be arranged in a suitable combination on panel A-C, with three variants being described.

The panels A-C are always rectangular, i.e. with two sides parallel to each other (first and third sides are parallel, and second and fourth sides 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 the bottom U to the beginning of the profile 1-3. This front edge 101 serves as a stop edge when connecting two panels A-C to one another and forms the visible joint between the panels A-C that is closed towards the top O of the panel A-C.

The basic principle and the individual profiles 1-3 are initially described using panel A. In Figure 1 a perspective view of a panel A is shown for illustration. 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 on the other two sides (sides one and three) two further, different profiles, namely a tongue-and-groove profile 1 and a double-tongue 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 groove double-spring 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 end edge 101 with a groove depth n4 and a groove width N5. This groove 102 serves to receive the upper tongue 105 of the groove double-tongue profile 3 when profiles 1 and 3 are connected to one another, as in FIG Figure 6 shown. Adjacent to 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 nose 103 (from the rear end of the groove 102 to the front end of the spring nose 103) has a tongue length f5. This spring nose 103 is used to fit into the groove 106 of the groove double-spring profile 3 when profiles 1 and 3 are connected to one another, as in FIG Figure 6 shown. The spring 103 springs back on its underside in a thickness F2-F3 up to the front edge 101. This serves to accommodate the lower tongue 107 of the tongue and groove profile 3 when profiles 1 and 3 are connected together, as in FIG Figure 6 shown. It then jumps back 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 FIG Figure 8 shown.

This in Figure 4 The double-tongue 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 protrudes over the front edge 101 in a tongue length f3. This is followed by 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 in FIG Figure 6 shown. Subsequent to the groove 106, a lower tongue 107 is provided, which protrudes maximally up to the (imaginary line along the) front edge 101 and has a tongue thickness F4 and a tongue length f4. The total feather thickness F1 of the double-tongue profile 3 is composed of the tongue thicknesses F4 and F5 of the tongues 105 and 107, as well as 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, ie 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 one another, as in Figure 7 shown. In this variant, the double tongue 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 on the lower edge or upper edge of the groove 109 with the total groove width N1 of the profile 2 inserted and connected to it.

This in Figure 5 The groove profile 2 shown has a groove 109 adjoining the end 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 directly adjoins the front edge 101 and is formed as a fold 110, which serves to block the upper tongue 105 of the double tongue profile 3 to the top O of the panel AC, if profiles 2 and 3 are connected to each other, 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, that is, 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 FIG Figure 8 shown. Starting from the groove depth n3 and adjoining the groove 108, there is a third area which has a groove width of N2-N3. The upper edge of a lower groove cheek 111 of the groove profile 2 is then provided on this. The groove cheek 111 protrudes at 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 protrudes beyond the front 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 the profile 3, but also to be pushed under the lower edge of the tongue 104 of the profile 1, so that a locking of the groove cheek 111 in the direction Top O of the panel AC takes place.

In Figure 9 shows an example of laying several panels A at a 90-degree angle to one another. This example shows a herringbone pattern that can be laid with several panels A without additional aids such as additional springs or additional cut-outs, i.e. reworking panels. This means that the proposed three different profiles on a panel AC enable such patterns to be laid with only one type of panel A, B or C. There is therefore no need, as in the prior art, two different panels (left and right panel) with two profiles, more precisely a groove profile lengthways and crossways and a tongue profile lengthways and crossways.

In Figures 10-12 comparatively three variants of AC panels 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 groove-double-tongue 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 groove double-tongue 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 AC panel with two long and two short sides, the second and fourth side are the short side, i.e. the transverse profile.

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

Profiles 1-3 are created by horizontal profiling, i.e. different from glueless installation 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, cubes, lichen, bandage, irregular bandage and cassette can be implemented. The laying pattern results from laying panels A or B or C at a 90 ° angle. So right and left panels are no longer required. It is also no longer necessary to edit standard profiles in order to implement such patterns.

In the variant with panel A, it is also possible to lay the panels linearly as in Figure 16 to be realized when the groove cheek 111 of the groove profile 2 is cut off in such a way that it is flush with the end edge 101 or is shorter than this (see Figure 15 ). The comparison between groove profile 2 and groove profile 2 with truncated groove cheek 111 is shown in FIG Figures 13 and 14 shown, with the in Figure 14 Groove profile 2 shown with cut groove cheek 111 is also referred to below as profile 4.

In Figure 15 two interconnected panels A with profile 4 are shown, that is, 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 spring FF. The external spring 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, that is to say the distance between the lower edge of the fold 110 and the lower edge of the inner groove 108.

By changing profile 2 into a profile 4 without a groove cheek 111, a linear installation can be implemented, as in FIG Figure 16 shown. This means that further laying patterns can be implemented.

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, in particular laying at a 90 degree angle, including herringbone, can be implemented without additional aids. Due to the differently arranged profiles 1-3 on a panel A-C, the production of the panels A-C is easier and the feed rate is high. Also, no double storage is necessary and laying is easier and therefore faster.
