Abstract

The lower side of the panels (1) include a tile (5), at least locally.

Description

The present invention relates to panels for forming a Floor covering according to the preamble of claim 1.

A floor covering can, for example, be joined together by a flat surface of essentially rectangular panels be formed. Such panels can for example made of hard floor panels such as laminate panels, Veneered parquet, finished parquet or other trained his.

The individual panels traditionally instruct the sides grooves respectively. Springs with which they are among themselves can be positively connected. The non-positive Connection of the panels can essentially be based on two types are made, namely by using the panels with each glued or. otherwise connected or by gluing the panels together, preferably via the tongue and groove connection, or by means of a positive connection Fasteners are connected together. In the second case, if the panels are only loose on the Lying underground is also often of floating or floating parquet.

The advantage of floating or floating parquet is, among other things, that through this manufacturing method any shrink response caused by temperature and humidity. Expansion movements can be absorbed and do not lead to tension, as is the case with glued parquet can occur.

With the floating resp. pending laying will the installation of the panels is usually an impact sound tile laid out on the ground. This is often the case Flies pulled from rolls in certain widths and accordingly tailored to the size of the floor and laid out. So that the panels come to rest flat on it, the flow tracks should be as smooth as possible and without formation of hulls to rest on the floor. Especially with subsequent laying of the panels always exists the risk of shifting the underlying flow sheets.

With the floating resp. floating laying of the panels without gluing there is still the problem that the Gaps between the individual panels sensitive to moisture and moisture and are therefore sealed subsequently in order to swell the panel body on this Place to avoid.

The object of the present invention was now to To provide panels for the formation of a floor covering, which except for the cut to the appropriate Floor size directly on the surface without further preparatory work are relocatable.

According to the invention, this object is achieved by panels with the Features solved according to claim 1.

Preferred embodiments of the invention result from the features of further claims 2 to 10.

The inventive construction of the panels with an integrated Flies, which serves as impact sound absorption, the panels can be applied directly to the substrate in one operation be relocated. On the one hand, this has the advantage that the laying compared to conventional panels can be done faster and on the other hand, the input problems described with the previously to be interpreted Flies avoided.

The combination with pre-assembled has proven to be particularly advantageous Connection brackets proved. So it is possible without additional connecting means such as Glue or clips to be added later to create a floor covering quickly and easily, which a reliable connection of the individual panels with each other. Except for cutting the panels to length Border area to adapt to the size of the one to be created Floor no longer need additional work be performed.

If the side edges are already fully sealed, can be a moisture-insensitive, low-impact sound Simply floor from the individual, pre-assembled Panels are built. This is particularly advantageous Version for laminate parquet panels, which because of their pronounced tread resistance can be estimated.

Exemplary embodiments of the present invention are explained in more detail below with reference to the drawings. Show it

Figure 1 is a view of a section of a panel floor under construction with conventional panels.

FIG. 1 shows the top view of a panel 1 Flooring in the construction phase. The panels 1 are on the floor tracks 2 applied and tongue and groove connection over the side edges offset with each other in the longitudinal direction of the panel connected. The connection can, for example by means of glue, which after hardening also for sealing the butt groove of neighboring panels serves.

To the one hand the disadvantages described in the introduction of to clear the flow tracks 2 to be laid beforehand and on the other hand also to simplify the laying itself According to the invention, panels 1, 1 'are proposed, which already equipped with tile 5 on the underside are, as shown in Figure 2 in cross section is. At the bottom of the panels 1 resp. 1 'which over the spring 3 formed on the side edges. Groove 4 ' are connected to each other is already a tile 5 resp. 5 'attached.

The tile 5 resp. 5 'preferably consists of a synthetic Fabric, preferably of a polyester fleece, and is preferably with the underside of the panels 1, respectively. 1' glued.

Preferably, the tile 5, respectively. 5 'offset from the top of the panels 1, 1 'in the same extent arranged like the top of the panels 1, 1 '. That's enough for example the side edge of the tile 5 in FIG. 2 up to the extent of the spring 3 of the panels 1, while the side edge of the tile 5 'inwards up to the height of the groove bottom of the groove 4 'is offset. So that will prevents a continuous gap from the bottom side what is formed to the bottom of the tongue and groove connection among other things, the positive impact sound behavior of the panels 1, 1 'supported in connected and installed condition. The connection of these panels designed according to the invention can be secured by gluing, for example become.

Of course, other designs of the spring are also 3 resp. Groove 4 'can be used, in particular self-locking formations to form a snap lock.

Panels 1, 1 'according to the invention are preferably by means of connecting brackets attached to the underside of the panels 1, 1 ' 5 held together, as shown in Figure 3 in Cross section is shown. These are preferably made of metal, such as spring steel, existing connecting brackets 6 grab with their hooks bent upwards Tongues 7 and 8 formed in the underside of the panels 1, 1 ' and running parallel to the side edges Grooves 9 and 10 on.

In this version, the tile 5, respectively. 5 'like this offset with the underside of the panels 1, 1 ' connected that the one side edge of the tile 5 to the End of the tongue 8 of the connecting clip 6 is sufficient the other tile 5 'up to the inner edge of the groove 10 enough and this for the engagement of the end 8 of the Leaves connection bracket 6 free. This is through the view illustrated in Figure 4 on a single panel 1.

In Figure 4 is also the preferred embodiment of the connecting bracket 6 in Y shape with parallel side edges clearly visible. The tongue 7 is in two individual Tongues 7 resp. 7 'divided, as well as the additional Tongue 11 in two tongues 11 arranged in a line resp. 11 '. This arrangement now results in a stable connection with the panel 1, which is also in a longitudinal displacement of the two panels 1 and 1 'do not tilt towards each other can. So that the tongues 7,7 'resp. 11.11 ' resp. 8 always connected in parallel when connected the corresponding grooves 9.10 respectively. Gap 12 of the panels 1 resp. 1 'arranged and omit a longitudinal displacement Maintaining an effective locking of the two Panels 1 resp. 1 'perpendicular to their connecting edges to. It is precisely this embodiment of the connecting bracket 6 is particularly suitable for pre-assembly and training the panels according to the invention, since on the one hand they have a stable connection guaranteed, but also retrospectively can be easily moved along the grooves 9, if this is necessary for the connection, especially in peripheral areas would.

In Figure 5 is still the supervision of one of the inventive Panels 1, 1 'of the floor shown, in which the position of the connecting brackets is dashed 6 is shown. So there are preferably four each Connection brackets 6 along at regular intervals the longitudinal edges of the panels 1, 1 'and a connecting bracket each 6 arranged on the transverse edges of the panels 1, 1 '.

For the use of such panels 1, 1 'in the living area the base body of the panels 1, 1 'typically has one Thickness of about 8mm and the tile 5, 5 'a thickness of 3mm.

This is especially true for laminate panels according to the invention no additional work processes are necessary after laying the side edges of the panels 1, 1 ' preferably fully sealed and therefore insensitive on the influence of moisture or water. Since just at the use of connecting clips 6 a glue the joints are no longer necessary, the sealing can already applied beforehand.
