Since the novelty carried out after the utility model has been deposited Examination showed that the subject of the utility model not only to delimit is opposite the DBGM 1 816 736 of the utility model owner, but It is also to be distinguished from the still determined French patent 86I 156 »were within the priority year Foreign registrations submitted, which were delimited accordingly are.

New documents in triplicate, the are also delimited from the prior art that became known after filing the application, handed over and it is asked to attach these documents to the official file on the one hand and to the documents displayed on the other.

Artificial stone, in particular molded concrete stone.

The invention relates to an artificial stone, preferably concrete block, with at least in the top surface of mutually parallel tipping grooves and at least two parallel webs which run along the same web , each web having a length which is greater than the distance of the outer * fläGhen the outer ribs ^ und.sich the Quepsqhnitt of, sswischen "constantly expands the Bippen lying cavities of the iintereeitenflapke ^ Aur top surface d <$ s stone '' Kunstförrasteiae this _kind. have been developed by the inventor and known * This art form stones with the same or similar \ ^ stones as ünterlaga "especially for vehicles parke'nde _t used and have the; advantage". that an area covered with such artificial stones appears as a grassy area>; if xn of the cavities or "breakthroughs filling JJrde grass has been sown. .

Art forms t'eijie ■ of the type mentioned at the beginning can be resolved / against » above, to the ground, because the * Cross-section of the cavities lying between the hips of the The bottom surface is steadily widening to the top surface of the stone, whereby “after the formation of the sras root felt a good one Anchoring of the "artificial stone against the earth" is aimed becomes »apart from the fact that thereby also the underside surface each stone is larger than the top surface, i.e. of. Pressure forces acting upwards and downwards affect a larger one Distribute the area, but this anchoring ^ is not always sufficient

to anchor such Kunstformstexne in such a way that they at. Load, for example, from heavy vehicles such as trucks or the like, their. Do not change position in relation to the ground. The fact that this - known art - even when the grass roots are formed, "felts" are not always firmly anchored in the ground, is due to the fact that all the surfaces of these artificial stones that are opposite the surfaces of other stones run in perpendicular planes between opposite ones - no root felt is formed on perpendicular surfaces of different stones, even if a cavity is formed between mutually facing surfaces of parallel lying ribs of adjacent stones, - there. which are perpendicular to these: rib surfaces.

Her invention is based on the object die'vorerwähnten To design synthetic bricks in such a way that "they" position themselves in the bond even when driving on with relatively high loads "and when there are" substance loads ", for example caused by the Landing an airplane, not “being able to change” to solve this The object is proposed according to the invention to ensure that each rib, has a length that. is greater than the distance-the outer surfaces of the two webs or the outer webs and, all.

"The external webs and all webs - also protrude to a certain extent with full cross-section over the external ribs. This not only creates an artificial stone" which is extremely stable, but also - after a relatively short time thanks to the after seeding of grass formed grass-Wurzelfilz is so securely fixed in the ground, _r;. that .he not change its position in the ground, even at relatively high loads and Stoßbeataspruchungen between all outer side surfaces of a stone "and the Äußenseitenflächen other stones is therefore a.

The one-piece molded concrete block has ribs 1, between which from the top surface to. Underside surface-penetrating cavities 2 are formed, which run parallel to the longitudinal side surfaces of the butts and which are designed so that their cross-section steadily widens from the underside surface to the 'upper side surface of the stone. The cross-section of such a cavity is therefore trapezoidal, with the longest of the two parallel sides of the trapezoid lying in the top surface of the stone . ^: "..;" .
