Abstract

The invention relates to a mat (1) to be positioned under a mosaic parquet, and intended to be fastened to the surface of the floor, the mat being considerably thinner than the parquet itself. In order to provide a mat which is rapid to lay, deadens efficiently the sound of footsteps, and eliminates disadvantages caused by moisture, the mat is entirely made of a flexible, stretchy material, it is impermeable to water, and the lower surface of the mat is self-adhesive and provided with grooves (4) or elevations (5), so that when the mat has been laid on the floor, channels are formed between the mat and the floor for removing water possibly entering between the mat and the floor.

Description

A mat to be positioned under a mosaic parquet
The invention relates to a mat to be positioned under a mosaic parquet and intended to be fastened to the surface of the floor, the mat being considerably- thinner than the parquet itself. This kind of mat is used primarily for deadening the sound of footsteps but also for protecting the floor covering against moisture from belo . Previously a usual practice has been to lay a layer of cork under a mosaic parquet for efficiently deadening the sound of footsteps. This practice ac¬ tually provides a good deadening effect as well as a good thermal insulation; however, the parquet is slow to lay in this way, since the cork has to be glued first to the floor and the parquet cannot be glued to the cork until the glue has been allowed to dry for several days. Furthermore, cork, which has good sound deadening properties, is relatively expensive to be used as a mat under parquetry. When cork slabs are used it is also possible that moisture enters the parquet from below between the cork slabs.
In addition, impregnated cardboard has pre¬ viously been used under mosaic parquet. Cardboard does not stretch and when glued tightly on the floor it is liable to tear as a result of the variation in the moisture and temperature, whereby moisture may enter the parquet through the torn points. Nor is cardboard sufficiently capable of deadening the sound of footsteps.
The object of the present invention is to pro¬ vide a mat by means of which the above-mentioned draw¬ backs can be eliminated. This object is achieved by means of a mat according to the invention, which is characterized by a combination of features such that the mat is entirely made of a flexible, stretchy ma¬ terial; it is impermeable to water; the lower surface of the mat is self-adhesive and comprises grooves or elevations, so that when the mat has been laid on the floor, channels are formed between the mat and the floor for removing water possibly entering between the floor and the mat.
The invention is thus based on the idea that the mat is formed of a flexible material and that it is impermeable to water as well as self-adhesive and provided with a lower surface such in shape that when the mat has been fitted on the floor, water possibly entering between the mat and floor does not cause the mat to come off the floor, for instance. Being flexible, the mat does not tear, and the self-adhesive quality of the lower surface of the mat makes the mat easy and rapid to lay.
When the mat comprises a separate primary layer and a layer impermeable to water thereunder, it is especially preferable to form the primary layer of flexible polyester which deadens the sound of foot¬ steps efficiently and provides good thermal insula¬ tion.
In the following the invention will de de- scribed in more detail with reference to the attached drawing, wherein
Figure 1 is a cross-sectional view of one embo¬ diment of the mat according to the invention;
Figure 2 is a cross-sectional view of another embodiment of the mat according to the invention;
Figure 3 illustrates an alternative embodiment of the mat according to the invention from below; and
Figure 4 illustrates the mat according to the invention when laid between the floor and the parquet. The mat of Figure 1 comprises a primary layer la preferably of polyester, and a layer 2 made of a material impermeable to water, such as bitumen, and fastened to the lower surface of the primary layer. The lower surface of the mat 1 comprises grooves 4 which in this specific case are formed by the bitumen layer 2 impermeable to water. The lowest layer of the mat is formed by a thin adhesive layer 3. It is abso¬ lutely necessary to provide the mat with the adhesive layer 3 in advance, since an adhesive applied subse- guently to the surface of the mat or the floor when the mat is being laid would easily fill the grooves 4. Figure 2 shows another preferred mat structure 10 which comprises, similarly as in Figure 1, a pri¬ mary layer la and a water-impermeable layer 2 fastened on the lower surface of the primary layer. In this case, however, the mat 10 is made self-adhesive by means of mutually spaced adhesive stripes 3' provided on the lower surface of the layer 2, whereby non-ad¬ hesive grooves 4 are formed between the stripes 3'. Accordingly, it is not necessary to form the grooves 4 by means of the water-impermeable layer 2, and the bottoms of the grooves are not unnecessarily provided with an adhesive.
In Figure 3, the bottom of the mat comprises elevations 5 which are formed e.g. by means of cross¬ wise grooves 4 formed on the underside of the mat.
In Figure 4, the mat 1; 10 according to the in¬ vention is laid between a floor 7 and a parquet 6. Channels 8 are formed between the mat 1; 10 and the floor 7. Water possibly entered between the mat and the floor can be removed or aired away.
The mat is laid simply by spreading it out on the floor and by pressing it in place. The adhesive is such that it is not necessary to wait until it is dry, but the parquet can be laid immediately on the mat. If the upper surface of the mat is also provided with a adhesive layer, the parquet can be laid particularl rapidly.
The description of the invention is merely in tended to illustrate the idea of the invention. In it details, the mat according to the invention may var within the scope of the attached claims. Accordingly the whole mat may be made of a polyester material im permeable to water, whereby the lower surface of th mat is provided with an adhesive layer. If the ma comprises a separate primary layer and a layer imper meable to water, the water-impermeable layer may whol ly be made of glue-like material.
