The invention also relates to a structural part comprising at least two interconnected components, in particular panels, in which a tongue profiled edge of one component engages with a corresponding groove profiled edge of the other component. The aim of the invention is to reduce the time and force required to lay the component. To achieve this, the tongue profiled edge and/or the groove profiled edge of the component is or are provided with a marking (5, 6).

Description

The invention relates to a component, in particular a panel, which can be joined together with at least one other component, wherein the component has a spring profile edge and / or a groove profile edge, which at least in sections can be brought into engagement with a corresponding profile edge of the other component. Moreover, the invention relates to a method for laying panels on a surface of a room.

Such components, in particular panels, are typically used for a floor covering, for example parquet or laminate flooring. Other workpieces can be composed of such components, such as ceiling panels, wall coverings, furniture or furniture parts, etc. In this case, the components joined to a workpiece need not necessarily be arranged in the same plane or form a plane, but can also at a certain angle be joined together.

In the following, a component in the form of a panel is described by way of example. A panel is a possibly multilayer, plate-shaped component, in particular made of wood material, for example from one or more layers of wood chips or fibers provided with binder and compressed, optionally with a laminate coating additionally applied as a finish.

The individual panels can be combined by a mechanical connection to a flat whole, so that laying the panels is usually possible without adhesives or additional mechanical fasteners, such as screws or nails. In particular, this results in the advantage that the panels can be laid without gluing and thus removed again.

The mechanical connection is usually a tongue and groove joint, ie a combination of interacting profile edges of the respective adjacent panels. The spring and the groove profile edge is advantageously shaped so that a vertical and / or horizontal locking, preferably in both directions, takes place, so that joined panels can not move apart easily. The spring or groove profile edge of the one component is at least partially formed corresponding to the groove or spring profile edge of the other component.

Panels of this type with a profile edge, which corresponds at least in sections with a profile edge of the other component are, for example, from WO 01/02669 , of the WO 03/074814 , of the WO 2004/009930 , of the DE 203 19 119 U1 , of the DE 203 19 121 U1 , of the WO 94/26999 A1 , of the WO 97/47834 A1 , of the WO 01/66876 A1 , of the WO 01/66877 A1 or the US 5182892 known.

Now, if laid with profiled edges panels or similar components, whether by a professional craftsman or a layman, so must Under certain circumstances, the person laying the panel may turn or turn each panel several times, so that when joining with the other panel, the profile edges that exactly correspond to each other engage with each other, ie always a spring profile edge with a corresponding groove profile edge. In other words, since a panel depending on its shape may have several different profile edges, but usually only a single of the many profile edges corresponds to the corresponding profile edge on the laid panel, it is often not obvious to the person laying at a glance how he should hold or align the panel. The turning and turning of each individual, to be laid panel costs a relatively long time and requires in the long run, especially for relatively large or bulky panels, also an additional effort of the person laying.

If such panels or similar components that provide profile edges are also laid, the laying person must, if appropriate, adapt the last component, in particular the panel, to a number of components arranged next to one another in size. In such a case, the laying person must first measure the space available for the component, for example, between the penultimate component and the wall, then transfer the determined measure to the blank part and finally separate the excess part. For example, the publisher must first grasp a measuring tape or a folding rule, then place it at the point at which the blank part is to be inserted later to measure the available space, and then the determined measure on the component by applying the tape measure or Folding sticks to the component and transmitted by marking. Especially when laying a floor in large rooms, these handles represent a significant loss of time.

The present invention is therefore based on the technical problem of further developing a component, in particular a panel, of the type mentioned at the outset in such a way that laying is less time and effort consuming.

The above-indicated technical problem is first solved in a component of the type mentioned according to claim 1, characterized in that the spring profile edge and / or the Nutprofilkante of the component has a mark which is formed as Längsmaßeinteilung and having spaced lines and numbers.

By such a marking of the tongue and / or groove profile edge as Längsmaßeinteilung, for example, by the profile edge, preferably the spring profile edge, printed, spaced-apart lines or the like, the person laying the components at a blank part at a glance can see how much of the original component must be detached so that it is suitable. As a result, the publisher does not have to measure the size of the space available for the component, for example, between the penultimate component and the wall, if this is the case, for example, if he wishes to adapt the size of the last component, in particular the panel, to a number of components arranged next to one another transferred measure on the cut part and finally separate the excess part. Instead, it is enough if the publisher is the last one Component of a number at the designated location applies, where he immediately recognizes by means provided on the profile edge longitudinal graduation, at which point the blank has to be made. So the publisher does not have to grab a tape measure or a ruler, then place it at the point where the blank is to be inserted later to measure the available space, then the measured dimension on the part by applying the tape measure or yardstick transferred to the component and by marking, but he only needs a single handle, with which he applies the zuzuschneidende component directly to the designated location. This represents a significant time saving, especially if a floor is to be laid in large rooms.

By such a marking of the tongue and / or groove profile edge, in particular if the markings of the two profile edges are different, the person laying the components continues to recognize immediately, which is the profile edge, which now applies it to the corresponding profile edge of the already installed component , In other words, it is thus recognizable at a glance on which side of the component to be laid, the groove profile and on which side of the spring profile is formed. Thus, the publisher can position the component right at the first gripping in the right way, so that he needs only a single handle for the assembly of two components. This saves the publisher a lot of time that would otherwise be required by turning and turning each component. Also, the force required for laying such components, especially if they are large or bulky, is reduced.

Another advantage in addition to the improved distinctness of the individual profile edges is that a manual for laying the components, especially panels, for laymen can be formulated in a way that is easier to understand, for example technical terms such as tongue and groove, which may not be familiar to everyone, by the note can be replaced on a specially marked profile edge. Since according to the invention it can be tactile and / or optical markings, for example a color marking, it could be explained in a corresponding laying instruction, for example, that the "red edge" is always to be engaged with the "green edge" during installation , Especially when components to be laid have a multiplicity of different profile edges, a corresponding installation instruction can be kept very easy to understand by using a corresponding number of colors.

The marking can be printed according to a further embodiment of the component according to the invention. The imprinting is preferably carried out by means of a digital printing method, which allows, in particular when imprinting a longitudinal graduation, a high degree of accuracy of the individual components of the marking, for example the lines spaced apart from one another. Particularly suitable, especially using a digital printing method, the ink jet printing has proven.

Alternatively or additionally, it is also conceivable that the marking by thermal treatment of the component is produced. A thermal treatment can lead to a change, in particular to a discoloration, of the component surface. Preferably, the thermal treatment, in particular a burn-in of the mark in the component, by means of a laser. As a result, a particularly high operating speed can be achieved, at the same time ensuring high precision. The method, in particular the laser method, enables a high accuracy of the components of the marking, for example the individual lines of a longitudinal graduation.

According to a further embodiment of the component according to the invention, the marking may have a structure, in particular a three-dimensional structure. Of course, structurings and color markings can also be combined with one another or one profile edge has a colored marking, whereas the other profile edge has a structure, for example a three-dimensional structure.

The structures mentioned may be a regular structure or an irregular structure. In particular, the structure may be a wavy or corrugated structure. The structure can be incorporated directly into the material of the component or the material of the profile edge, for example, embossed.

The marking, in particular the structure, but may alternatively or additionally also be formed by an applied coating. The coating may contain one or more colored substances, in particular to form a filling compound, a pre-bonding, a Lubrication and / or a seal included. A filling compound can serve, for example, to fill gaps in the region of the profile edges. For example, a pre-bonding has the advantage that, after assembly of the components, automatic bonding thereof can be achieved. By lubricating the assembly of the components can be facilitated. With the help of a seal, finally, the component can be protected from the ingress of moisture. The coloring of at least one of the substances contained is provided so that the coating is readily perceptible as a marking and differs in particular in its color from the substrate to which it is applied.

According to a further embodiment of the component according to the invention, it is provided that the spring profile edge and / or the groove profile edge of the component is provided with the marking at least in sections, for example only in the region of the corners. It is therefore conceivable that the profile edge only partially has a mark. Alternatively, the entire profile edge can also be provided with the marking.

According to one embodiment of the component according to the invention, the spring profile edge forms a mechanical locking with the groove profile edge. However, it is alternatively or additionally also conceivable that the spring profile edge with the Nutprofilkante, at least partially, is glued.

The invention also relates to a method for laying panels of the type mentioned according to claim 8, which allows a little time and kraftaufwäntiges laying.

The invention will be explained in more detail below with reference to an embodiment, for which reference is made to the accompanying drawings.

• Fig. 2 ein Ausführungsbeispiel eines erfindungsgemäßen Bauteils mit einer Markierung in einer perspektivischen Ansicht.

In the drawing show:

• the FIGS. 1a ) to c) in cross-section an embodiment of two zusammenfügbarer components, each with each other corresponding profile edges, and
• Fig. 2 An embodiment of a component according to the invention with a marker in a perspective view.

Fig. 1a ) shows a detail of a first component 1, this is a floor panel, with a spring profile edge 2, at least in sections with the groove profile edge 3 of in Fig. 1b ) corresponds to second component 4 corresponds.

The spring profile edge 2 of the first component 1 in this case has a marking 5, which extends over the upwardly directed surface and the side of the surface of the spring profile edge 2. The marking 5 is an optical marking, namely an applied color layer. In the present case, the color mark is a red mark, since such a color has a signal effect and the publisher is noticeable at first glance.

The second component 4, which in Fig. 1b ) is also provided with a mark 6 on the groove profile edge 3, which is engageable with the spring profile edge 2 of the other component 1 in engagement.

Also, the mark 6 is formed by an applied color layer, in which case the color was chosen to be green, as it represents a good contrast to the color red and the rest, as well as the color red, stands out well from the color of the rest of the component.

So that the mark 6 is clearly visible to the publisher at first glance, this is applied to the upwardly directed and to the publisher surfaces of the profile edge.

Fig. 1c Finally, the two components 1 and 4 in the assembled state, wherein the engaged profile edges 2 and 3 form a mechanical interlock, which prevents the two components can move apart in the assembled state.

An embodiment of a component 4 according to the invention with a marking 6 is shown in FIG Fig. 2 shown. Thereafter, a marking 6 is provided in the component 4 on the Nutprofilkante 3, which is formed as a longitudinal graduation. The Längsmaßeinteilung has along the Nutprofilkante 3 a plurality of juxtaposed strokes, wherein adjacent bars always have the same distance from each other. In the present embodiment, each 10th stroke is additionally provided with a printed number. Here, "10" ... "20" ... etc. The mark having the dashes has been applied to the groove profile edge 3 with high accuracy by a digital ink jet printing method.

A component 4, as it is in Fig. 2 is shown, is particularly suitable as a blank part, since the publisher can see at a glance, at which point he must remove the excess part of the component 4, so that this is suitable. It is conceivable, for example, when laying a floor covering to provide a certain percentage of the panels to be laid, which corresponds to the expected number of blank parts, with a marking in the form of a longitudinal graduation. Of course, it is also conceivable to provide all components with a corresponding mark.

Although according to Fig. 2 the marking in the form of a longitudinal graduation on a Nutprofilkante 3 is shown, it is also conceivable to provide such Längsmaßeinteilung on a spring profile edge. It is also conceivable to combine different types of marking with one another, for example a continuous color marking of a specific profile edge type, for example a continuous red profile edge for identifying a spring profile edge and a continuous green profile edge for identifying a groove profile edge, in conjunction with a longitudinal dimensioning independent thereof.
