Description

The invention relates to a device for connecting floor panels to a Wood-based core, especially MDF or HDF, on at least one side are provided with a dovetail-shaped groove in cross section.

From US 4,426,820 panels for forming a sports floor are known, the are provided with a dovetail groove on one side. On the opposite On the opposite side, the panel is provided with a spring, the cross section of which Cross-section of the groove corresponds. Two panels can be joined together by the one panel with the tongue side in the other panel with the groove side in Direction of the connection is inserted. These panels are made of plastic Untitled. Plastic has the property that the tongue and groove profile during manufacture the panels can be molded on. Plastic also has the advantage no or only very small dimensions caused by environmental influences subject to change.  

The dovetail profile itself has the advantage of being high in its transverse direction To be able to transfer forces. To exclude play in the connection, the Groove and the tongue are made very precisely and coordinated. Panels Wood or a wood-based material are subject to strong changes due to environmental factors rivers. Rising air humidity, for example, causes the material to swell. A dovetail groove would be reduced in cross-section, a congruent designed spring enlarge in cross section, so that the spring and the Nut no longer fit together and a connection of two panels with one of the Art designed tongue and groove profile may not be possible. Vice versa a decrease in humidity causes the material to shrink. A groove increases in cross section, the cross section of a spring is reduced. In one In such a case, a game could arise in the connection that would not be tolerable. In the case of floor panels, play in the connection would lead to the Ver binding edge of the surface creates a slit. Here moisture (liquid) can penetrate, which would cause the panels to swell in the joint de. The floor would be unusable after a short time because it would either linger would or would get tension cracks.

DE 25 05 489 A1 discloses demountable plastic floor panels that are attached to their Edges are reinforced with an aluminum rail into which a dovetail shape groove is introduced. Via several dovetail-shaped connecting elements elements can be connected to each other. Lie after the connection the plates close together over their full height. Floor slabs designed in this way can only be installed if the connection point is free of dirt, is especially dust-free. Otherwise, intolerable tensions can arise hen. The additional aluminum rails make the base plates more expensive. For a decoration Such a design is not suitable because the aluminum rail is visible at the top. A base plate made of a wood material can not worked as precisely on the edges as an aluminum rail. Insbeson it is always to be expected that wood dust is present in the connection point, which inevitably arises when the profile is milled.

Starting from this problem, a device described at the outset is intended be created that connect at least two floor panels with one The core made of wood-based material makes it easy and there is no play in the connection guaranteed even with changing environmental influences.

To solve a generic device is characterized in that the Bo another swallowtail on the side opposite the groove has a shaped groove, the grooves are mirror-symmetrical, into the grooves in the longitudinal direction insertable connecting element is designed so that both nu ten are almost completely fillable, and two floor panels over the in the grooves inserted connecting element without play with each other in horizontal and vertical Direction are connected and the interconnected panels only in the area of Abut the top against each other and otherwise above and below the connection tion element free spaces are formed.

The panels are very recessed due to the mirror-symmetrical design of the grooves manufacture. About the tolerance of the connecting element that can be inserted into the grooves mentes can the pre-tension that ver in the junction of two with each other bound panels prevail, can be adjusted. By a correspondingly high pre voltage, the connection point on the surface of the panels is sealed so that no moisture can penetrate. A change in humidity consequently, the surrounding area does not have an immediate effect on the connection binding site. The fact that the interconnected panels only in the area of Abutting the top against each other can result in a very high pretensioning force on the connector to take effect. The free spaces below the junction serve as Dust pockets, in which inevitable wood dust when connecting the panels can be pressed into it. There is also a static over-determination on the Connection point excluded.

The connecting element can be made of plastic or another material (for example wood or metal). If plastic as material  is used, this offers the advantage that very inexpensive production is possible is dimensionally stable and can be ensured with simple means.

The connecting element can already be inserted in a groove in the panel at the factory be (for example glued) so that the panels are only pushed into each other have to. In the case of long panels, for example, a plurality of such connections can be made tion elements placed one behind the other and spaced apart in the one groove become.

With the help of a drawing, an embodiment of the invention is briefly below are explained. It shows:

Figure 1 two interconnected panels in partial cross-section at the junction.

FIG. 2 shows a connecting element in cross section;

Fig. 3 one of the panels of the embodiment in partial cross section.

The panels 1 , 2 ; consist of a wood-based material, such as MDF or HDF. On two opposite sides (long side or transverse side), the panels 1 , 2 are provided with a groove 3 , 4 with a dovetail-shaped cross section. The grooves 3 , 4 are mirror-symmetrical to one another. For connecting two panels 1 , 2 , these are placed against one another with their edges 3 and 4 , and the connecting element 5 is inserted from the front into both panels 1 , 2 . The cross-section of the connecting element 5 corresponds to the opposite grooves 3 , 4 and fills them up essentially completely, so that a play-free connection is set both in the vertical direction R V and in the horizontal direction R H.

In order to increase the tension at the connection point, the panels 1 , 2 abut each other only in the area of their top side 0. Otherwise, 5 free spaces 8 , 9 are formed at the connection point above and below the connection element. Fig. 3 shows that the lower lip on the groove 3 ( 4 ) stands back from the upper lip and the upper lip is chamfered.
