Description

The Invention relates to a floor board that at least one carrier layer and has a cover layer, with on the 1st and 2nd long sides and interlocking on the 1st and 2nd transverse sides of the carrier layer Dome grooves and dome springs as well as interlocking 1st and 2nd Dome beads and 1st and 2nd dome channels are provided.

Such a floor board is for example in the scope of DE 297 10 175 U1 known. It has proven itself in the creation of parquet and laminate floors and can be easily and quickly installed by hand.

It in practice, there is now a desire to also have flexible elastic Materials in the form of floor boards assemble to larger floor areas to be able whereby not only the laying can be carried out quickly and easily but a floor area also non-destructive disassembled and can be used again in another place.

The Accordingly, the invention is based on State of the art - the Task based on a floor board to create that fully meets the needs mentioned above.

This Object is achieved with the features specified in claim 1.

A such floor board basically consists of a carrier layer and a top layer. The backing layer can consist of wood, wood-based material and / or plastic. A well known Material is MDF / HDF. The cover layer consists of a compliant elastic material, e.g. Cork, linoleum or carpet.

The 1st and 2nd long sides and the 1st and 2nd transverse sides of the floor board according to the invention are now with such dome grooves and dome springs or such 1st and 2nd dome beads as well as 1st and 2nd dome channels provided, which allow two floorboards over their 1st and 2nd long sides as well easily push their 1st and 2nd transverse sides together in an angled position and after pushing it together by lowering it into a common one horizontal plane to be able to lock that in that horizontal plane Unlocking not possible on level is. There is no special mounting bracket to take into account since there are no sensitive edges to consider. Rather, at Bend the elastic materials of the cover layers easily be deformed so that there are no negative effects on their edges to make noticable.

The Invention thus creates the prerequisites for the fact that floorboards are now available with relatively thick cover layers made of flexible elastic materials can be laid easily and optically flawless even by laypersons.

to Laying the floor board according to the invention a screed is considered to be the optimal substrate. The floor board but can also on a wooden or stone floor or even a carpet be relocated. No glue or mortar is required, one floor surface from several Floor boards according to the invention manufacture. Gaps between the floorboards do not need necessarily filled out to become. The joint width is due to the locking of the support layers the floorboards Are defined.

It it is also conceivable that between the carrier layer and the cover layer another layer, for example, an impact sound insulating layer can be.

The faces the backing layer and the top layer on the first long side and the 1st transverse page can be aligned in the same vertical plane according to claim 2. But it is also conceivable that the cover layer compared to the Carrier layer protrudes.

According to the characteristics of claim 3 can the side faces the backing layer on the 2nd long side and the 2nd transverse side opposite the one above lying side faces be in front of the top layer. Due to the resilient elastic Material of the cover layer, however, it is conceivable that the side surfaces of the backing and the cover layer lie in one and the same vertical plane or that the top layer is even opposite the backing layer protrudes.

The perfect locking of the 1st long side and the 1st transverse side a floor board with the 2nd long side and the 2nd transverse side of another floor board comes with the features of claim 4 further improved.

The Invention enables it according to claim 5 that the thickness of the cover layer is approximately the thickness the backing layer equivalent.

A advantageous connection of the carrier layer with the top layer consists in the features of the claim 6. Such an adhesive layer can optionally also impact sound be isolating.

The The invention is illustrated below with reference to the drawings embodiments explained in more detail. It demonstrate:

1 a floor board in plan view;

2 a partial enlarged vertical section through the representation of the 1 seen both along line II-II in the direction of arrows IIa and along line III-III in the direction of arrows IIIa;

3 in vertical section an assembly state of two floorboards in the area of their 1st and 2nd long sides or their 1st and 2nd transverse sides and

4 in vertical section two coupled floorboards in the area of their 1st and 2nd long sides or in the area of their 1st and 2nd transverse sides.

With 1 is in the 1 called a floor board. The configuration of the floor board 1 is slim rectangular. This results in 1st and 2nd long sides 2 . 3 as well as 1st and 2nd transverse pages 4 . 5 , About these 1st and 2nd long sides 2 . 3 as well as 1st and 2nd transverse pages 4 . 5 can the floor board 1 , as explained in more detail below, with further appropriately designed floorboards 1 be joined to a closed floor surface.

The 1st long side 2 and the 1st transverse page 4 on the one hand and the 2nd long side 3 and the 2nd transverse page 5 on the other hand, they are identical.

As in this context 2 to 4 the floor board exists 1 from a carrier layer 6 made of MDF / HDF and one with the backing 6 glued top layer 7 made of a resilient elastic material, such as a carpet. The thickness D of the top layer 7 corresponds approximately to the thickness D1 of the carrier layer 6 ,

When looking at the 1 and 2 can be seen that the backing layer 6 on the 1st long side 2 and the 1st transverse page 4 in the lower height area opposite the side surface located here 8th protruding tongue 9 having. The tongue 9 extends along the 1st long side 2 or the 1st transverse page 4 ,

In the tongue 9 is an open top dome with a trapezoidal cross-section 10 educated. This 1 , dome channel 10 lies in front of the side surface 8th , All longitudinal edges of the 1st dome channel 10 are rounded. End of the tongue 9 there is an upward-facing first dome bead 11 with a substantially trapezoidal cross-section.

The surface areas 12 and 13 next to the 1st dome channel 10 run in a horizontal plane.

The bottom 14 the backing layer 6 goes in the area of the 1st dome bead 11 in a 45 ° bevel 15 about.

Above the tongue 9 is in the side surface 8th the backing layer 6 a dome groove 16 incorporated. The dome groove 16 consists of an upper horizontal groove wall 17 , a lower inclined flat groove wall 18 and one the two groove walls 17 . 18 connecting, concave rounded groove base 19 together. The inclined groove wall 18 runs smoothly in the area 13 next to the 1st dome channel 10 on.

The side surface 8th the backing layer 6 and the side surface above 20 the top layer 7 are aligned in the same vertical plane VE.

Looking at the 1 and 2 also reveals that the carrier layer 6 on the 2nd long side 3 and the 2nd transverse page 5 in the middle height range one opposite the side surface there 21 protruding dome spring 22 has. The dome spring 22 is in terms of its cross section to the cross section of the dome groove 16 equalized.

Below the dome spring 22 is the backing layer 6 with a downward facing, cross-sectionally trapezoidal second dome bead 23 Mistake. The 2nd dome bead 23 is opposite the side surface 21 staggered. Its long edges are rounded.

Next to the 2nd dome bead 23 extends a 2nd dome channel 24 with a trapezoidal cross section. Its corner areas are also rounded. The 2nd dome channel 24 goes over a 45 ° bevel 25 in the bottom 14 the backing layer 6 about.

From the 2 it can be seen that the mean width B of the 1st dome bead 11 on the tongue 9 and the mean width B1 of the second dome bead 23 on the 2nd long side 3 and the 2nd transverse page 5 the backing layer 6 each about a third smaller than the mean width B2 of the second dome channel 24 on the 2nd long side 3 and the 2nd transverse page 5 or the mean width B3 of the 1st dome channel 10 on the tongue 9 are measured.

It is also from the 2 still visible that the side face 21 on the 2nd long side 3 and the 2nd transverse page 5 above the dome spring 22 With a return 26 Is provided.

The side surface 21 the 2nd long side 3 and the 2nd transverse page 5 is opposite the side surface 27 the top layer above 7 upstream, that is, the side surface 21 the backing layer 6 and the side surface 27 the top layer 7 extend in different parallel vertical planes VE1 and VE2.

When joining two floorboards 1 over their 1st and 2nd long sides 2 . 3 or their 1st and 2nd transverse pages 4 . 5 the floor to be applied becomes plank 1 compared to the already lying floor board 1 according to 3 slightly angled, so far that the dome spring 22 into the mouth of the dome groove 16 dips in and the 2nd dome bead 23 above the 1st dome bead 11 on the tongue 9 located. Here, the longitudinal edges 28 of the top layers 7 of the two floorboards 1 are at a distance from each other or touch each other with limited deformation because the cover layers 7 consist of a resilient elastic material. Then the floor board to be attached 1 by swiveling down further with the existing floor board 1 be added, according to the representation of the 4 the dome spring 22 into the dome groove 16 engages and the 1st dome bead 11 on the tongue 9 in the 2nd dome channel 24 and the second dome bead 23 in the 1st dome channel 10 on the tongue 9 engage.

The second dome bead is supported here 23 with its outer inclined surface 29 on the inner inclined surface 30 of the 1st dome channel 10 off while the dome spring 22 in the dome groove 16 is centered. The floorboards to be joined 1 are securely locked together.

In this locking position there is a joint 31 between the cover layers 7 formed, which - as described - can be filled in or, depending on the local conditions, remains empty.
