Abstract
A floor panel (1) provided with corresponding, mechanical locking elements (7, 12) on at least two opposed sides (5, 6) thereof, and having a core (4), a walk-on surface (2) and a bottom surface (3). In order to provide a floor panel of this type with impact sound insulation in a structurally simple and effective manner, it is suggested that at least one recess (13, 19) is provided, which extends from said bottom surface (3) into said core (4).
Description
- The present invention relates to a floor panel of rectangular shape of the type defined in the generic clause of claim 1.
- Such a floor panel is known from EP 1 264 946. The known floor panel includes a sound insulation in the form of at least one sound insulation layer which is arranged on the side of the core facing the walk-on surface. The sound insulation layer is made of a thin, soft, resilient material, in particular a plastic material, and must be incorporated into the laminate during the production of the floor panel; this is comparatively complicated and expensive.
- WO 99/00242 shows a floor panel of rectangular shape comprising a core of solid wood and two thinner boards which are also made of solid wood and which are arranged on the upper and the lower side of the core. The floor panel is sound insulated; in a first embodiment, sound insulation layers are interposed between the core and the boards covering the core on both sides thereof, the drawbacks being the above-described ones.
- In another embodiment, the sides of the core which face the neighbouring thinner boards are provided with grooves by means of which the wood-to-wood contact area is reduced, so as to effect sound insulation. However, this arrangement also leads to a reduction of the force-transmitting area between the wood layers; in extreme cases, this may have the effect that, in floor areas which are frequently walked on, the vertices located between the grooves may flatten so that the floor will slightly drop there.
- In addition, the core has provided therein longitudinally extending grooves, which are incorporated alternately from the upper and the lower side, said grooves extending into the core over a distance corresponding to half the thickness of said core. These grooves are provided for the purpose of compensating the swelling and the shrinking of the wood in the case of humidity changes so that the so-called working of the wood will not cause distortions of the flooring. These grooves do, however, not extend up to the bottom surface, but they are covered by said thinner boards, which act as acoustical bridges. In addition, the solid-wood floor panels described are configured for glueing; the layers of glue extending between the panels produce a sound-insulating effect as well, so that the demands to be satisfied by an additional sound insulation are not as high.
- Finally, it is common practice to insert sound-absorbing layers of (needled) felt, plastic material, rubber or the like below the panels during floor laying, or said layers may be glued to the panels in the course of the production process; this is rather complicated and expensive.
- It is therefore the object of the present invention to provide a floor panel with an effective impact sound insulation which is easy to produce.
- This object is achieved by a floor panel provided with corresponding, mechanical locking elements on at least two sides thereof, and comprising a core, a walk-on surface and a bottom surface, wherein at least one recess is provided, which extends from said bottom surface into said core.
- It turned out that, surprisingly enough, it is possible to achieve for floor panels with mechanical locking systems, i.e. floor panels which are not provided with a layer of glue between the individual panels, an effective impact sound insulation by means of a recess extending from the bottom surface up to an into the core. In practical tests, it turned out that the impact sound can be reduced significantly, e.g. by 3 dB.
- Advantageous further developments of the present invention are disclosed in the subclaims.
- In the following, an embodiment of the present invention will be explained in detail making reference to the drawings in which:
-
FIG. 1 shows a perspective view of a floor panel according to the present invention, -
FIG. 2 shows the section II-II according toFIG. 1 , -
FIG. 3 s hows the section III-III according toFIG. 1 , -
FIG. 4 shows part of a flooring made of the floor panels according to the present invention, and -
FIG. 5 shows part of another flooring made of other floor panels according to the present invention. -
FIG. 1 shows in a perspective view a first embodiment of a floor panel 1 according to the present invention, comprising a walk-onsurface 2 and abottom surface 3, which cannot be seen inFIG. 1 and which serves as a contact surface that rests on a floor substrate, as well as acore 4 arranged between saidbottom surface 3 and said walk-onsurface 2. - The floor panel 1 shown represents part of a laminate floor, the walk-on
surface 2 being preferably defined by a laminate layer which is resistant to footsteps, insensitive to damage and dirt, and decorative. Thecore 4 is preferably made of an industrially produced wood fibre material, in particular an MDF/HDF board or a chipboard. Thebottom surface 3 is the bottom surface of thecore 4 consisting of the material of said core or it can be formed by a protection or compensation layer (here not shown in the drawing) which is laminated onto the core. - The floor panel 1 shown here is rectangular in shape and comparatively small; the width B ranges from 5 cm to 15 cm, and is preferably 8 cm, and the length L ranges from 20 cm to 80 cm, and is preferably 60 cm. The floor panel has therefore two opposed
long sides short sides 6 a and 6 b. At least thelong sides mechanical locking elements 7 a and 7 b by means of which neighbouring floor panels can be interlocked via a snap-in connection. The locking element 7 a comprises for this purpose astrip 8 with a projection 8 a which is delimited towards the inner side by agroove 9. Thelocking element 7 b includes arecess 10 for receiving therein thestrip 8, with an undercut portion 10 a for receiving therein the projection 8 a, saidrecess 10 being delimited towards the outside by astrip 11 which is adapted to be received in saidgroove 9. This allows the long sides of neighbouring floor panels to be interlocked through a snap-in connection; in order to do so, it will only be necessary to place the long sides of the two panels in contact with one another at an angle in such a way that the projection 8 a is introduced in therecess 10, and to orient the two panels subsequently such that they are brought into aligned, flat relationship with one another, whereby the projection 8 a will move into the undercut portion 10 a. The dimensions of thelocking elements 7 a, 7 b, in particular the widths b thereof, are adapted to one another in such a way that the two panels cannot be displaced relative to one another in a direction parallel to the short sides 6 a. - In the embodiment shown, also the two
short sides 6 a, 6 b are provided withcorresponding locking elements 12 a, 12 b; the locking element 12 a corresponds to thelocking element 7 b and thelocking element 12 b corresponds, in analogy therewith, to the locking element 7 a, but without the projection, so that the short sides of the panels can be connected to one another simply by pressing down, whereby the laying of the floor will be facilitated. - The connection via the
locking elements - The floor panel 1 according to the present invention is provided with a sound insulation, especially an insulation against impact sound, which is easy to produce and nevertheless effective, said sound insulation being provided in the form of at least one
recess 13 which extends into the panel from thebottom surface 3 thereof, saidbottom surface 3 being, with the exception of saidrecess 13, level and flat. In the embodiment shown, sound insulation is effected by asingle recess 13 extending in the form of a groove from one short side 6 a continuously up to the othershort side 6 b. Therecess 13 has a depth t which is dimensioned such that saidrecess 13 extends from thebottom surface 3 into thecore 4 over a distance corresponding to one third up to one half of the thickness D of saidcore 4. Therecess 13 is open and should also remain open towards thebottom surface 3. If actually necessary, however, it is possible to apply a thin layer, which does not establish an acoustical bridge, to thebottom surface 3 in such a way that saidrecess 13 is covered. Therecess 13 should, however, not lose its sound wave-interrupting function under any circumstances. - The recess has a width s between 1 and 10 mm and extends approximately in the middle between the
long sides long sides locking elements 12 a, 12 b of theshort sides 6 a, 6 b. From the outer strip of the locking element 12 a, a small connectingweb 14 can remain, which will improve the coherence. -
FIG. 4 shows a part of aflooring 15 which has been produced from a plurality of floor panels 1 according toFIG. 1 to 3.FIG. 4 shows the bottom surface of theflooring 15 and an arrangement of the floor panels 1 in which said respective floor panels are arranged in parallel and displaced by one half of their length, in the form of a regular plank flooring. As can be seen fromFIG. 4 , thelocking elements 7 a, 7 b as well as 12 a, 12 b of neighbouring floor panels are implemented such that, on the bottom surface of the flooring,grooves 16 are formed between the long sides of neighbouring panels andgrooves 17 are formed between the short sides of neighbouring panels, whereas the walk-onsurfaces 2 of neighbouring panels abut on one another almost without any intermediate gaps. This means that, with floor panels 1 having a width B of 8 cm, longitudinally extendingcontinuous grooves grooves 17 between neighbouring short sides serve to provide impact sound insulation. -
FIG. 5 shows a further embodiment of aflooring 18 consisting of a further embodiment of floor panels 1′ implemented according to the present invention, in the form of a herringbone flooring; also saidFIG. 5 shows thebottom surfaces 3. - The floor panel 1′ differs from the floor panel 1 only with regard to a deviating kind of recess, the recesses provided here being a plurality of individual, slot-
shaped recesses 19 which are disposed in an in-line arrangement one after the other. As for the rest, the structural design of the floor panel 1′ corresponds to that of the floor panel 1; in particular, the in-line arrangement of therecesses 19 is again disposed in the middle between and parallel to thelong sides short side 6 b. Also in the case of the herringbone pattern of theflooring 18,grooves 20 are formed for impact sound insulation between the long and the short sides. - As modifications of the embodiments described and shown hereinbefore, the recesses can be varied with respect to their shape, size (depth, width, length), arrangement and number. For example, two or more continuous recesses can be provided for larger floor panels, or a plurality of recesses can be distributed over the bottom surfaces in the form of rows, in a diamond shape or in some other kind of arrangement. The recesses need not necessarily be arranged such that they extend parallel to the long sides, but they may also be arranged along the short sides or at random. The recesses need not necessarily be implemented as grooves, but they may, for example, also be implemented as notches, blind holes, incisions or the like. It is not absolutely necessary that the floor panels are provided with locking elements on all four sides thereof; especially when the floor panels are laid in the form of a plank flooring, it may e.g. suffice to provide only the long sides with these locking elements. The shape and the mode of operation of the locking elements can be varied as well. The present invention can therefore be used for floor panels with all kinds of commonly used locking elements or for floor panels that have to be glued together. In addition, the present invention can be used for floor panels having other shapes and dimensions, including panels of normal size and standard size having dimensions of 120×20 cm, or panels with miter joints, square, hexagonal or the like. Also the material chosen for the floor panel can be adapted to changes in the intended use. Finally, all the embodiments of the floor panels are suitable for all commonly used laying patterns.
