发明名称 Paving stone
摘要 A paving stone, in particular concrete paving stone, is proposed, which serves for paving garden installations, paths and the like. As in the paving stone according to the main patent application P 3315843.6, the side surfaces are, with the aim of giving the paving covering as natural an appearance as possible, designed as plane surfaces and the transition surfaces between the side surfaces and the upper surface are rounded off and designed in such a manner that the boundary line of the transition surface to the upper surface is curved. For the purposes of better compaction of the concrete at the corners, these are drawn down so that the boundary line of the transition region to the side surfaces is likewise curved and specifically in each case runs, falling away, from the stone centre towards the corners.
