PLASTIC GRASS MAT - GRÄSMATTA AV PLAST

The present invention relates to a plastic grass mat used, for example, as a door, balcony or similar mat consisting of at least two layers, i.e. an upper and a lower layer, the upper layer being formed by grass tufts and a uniform plastic layer or lattice-like structure of the lower layer. formed integrally.

10 Plastic grass mats of this kind have become more common recently. They are especially used as door mats, windshield mats, and balcony and yard mats. They have the advantage of a pleasant, real grass-like appearance and the fact that, due to the rough surface, they act as effective removers of sand and other solid particles from the footwear. Sand accumulates on the top surface of the lower layer of the carpet (when the lower layer is uniform rather than lattice-like), but remains invisible under the grass tufts. In connection with cleaning, the sand and other particles are shaken off the mat from time to time.

One method of making such a plastic grass mat is disclosed in U.S. Patent 3,590,109. With regard to the prior art, reference is also made to EP application publication 204682 A2.

The object of the invention is to provide a plastic grass mat of substantially the same structure as before, which would facilitate the visibility of the mat in both dark and light conditions. The invention is characterized in that a plastic grass mat is formed with either a top or bottom layer or both in the dark by reflecting patterns by making a reflective pattern on the mat. in a manner similar to the structure of the rest, but of a different material from the rest of the mat.

A preferred embodiment of the invention is characterized in that the reflective patterns are longitudinal lines of the mat, so that certain longitudinal rows of grass tufts of the mat are made of a reflective material.

Another preferred embodiment of the invention is characterized in that the reflective patterns are longitudinal lines of the mat made of a reflective material for the lower layer of the mat.

Another preferred embodiment of the invention is characterized in that the reflective material is formed by adding a reflective dye to a conventional manufacturing material.

By means of the invention, the perceptibility of the carpet is improved in both dark and light. In addition, the reflective pattern makes it possible to improve the appearance of the carpet.

In the following, the invention will be explained by means of preferred embodiments with reference to the accompanying drawing, in which

Figure 1 shows a perspective view of a part of the structure of a plastic grass mat 20.

Figure 2 shows a very simplified and schematic top view of a grass mat with reflective patterns according to the invention.

25: Figure 1 shows a known grass mat structure made by the technique disclosed in U.S. Patent 3,590,109. The mat can also be manufactured by the technique described in the aforementioned EP patent application 204682. The actual manufacturing method 20 will not be explained in more detail in this connection, as it can be any known technique for manufacturing grass mats. It is essential in this manufacturing technique that the grass tufts 1 are continuously pressed in a mold and integrated into the lower layer 2 of the mat. The entire mat is preferably made of plastic.

Figure 1 of EP patent application 204682 shows a nozzle through which plastic material is fed to grass tuft notes on the surface of a drum-like part. Each longitudinal row of grass tufts has its own nozzle, so that they are located parallel to the normal plane of the image plane of Figure 1 of EP application 204682.

The invention can be implemented, for example, by feeding a reflective material from one or more nozzles, whereby a straight line of reflective material is formed in the final mat at the corresponding point. Of course, the technique 10 can be developed so that it is possible to make patterns of other shapes from the reflective material. The direction of the patterns, for example the line, naturally also depends on how the final mat is cut from the web.

15 It is further possible that patterns of reflective material are also or only made on the lower layer. This can also be easily accomplished with existing equipment by feeding reflective material through certain nozzles.

It will be clear to a person skilled in the art that the invention is not limited to the above-mentioned embodiments, but can be varied within the scope of the appended claims.

Claims (4)

1. Lawn made of plastic, which is used, for example, as a door, balcony or equivalent mat, formed by at least two layers, ie. of an upper (1) and a lower (2) layer, thus, that the upper layer is formed by lawns (1) and the lower layer by a uniform plane of plastic or by a network structure (2) in which the lawns are fixedly fixed, characterized by , that it is formed in the plastic lawn, either in the upper (1) or in the lower (2) layer or in each, samples (3) reflecting in the dark by producing the reflective pattern in a manner similar to that of the carpet other construction but of a different material than the other part of the carpet. 15 Lawn according to Claim 1, characterized in that the reflective patterns (3) are lines in the longitudinal direction of the mat, so that some of the mat's longitudinally oriented lawn rows are made of the reflective material. 2o Lawn according to claim 2, characterized in that the reflective patterns (3) are lines in the longitudinal direction of the carpet made of the reflective material in the lower layer of the carpet. 25 Lawn according to any of claims 1-3, characterized in that the reflective material is formed by adding a reflective dye to the ordinary fabric.
