Abstract (en)
[origin: US4572699A] A paving stone, especially a concrete paving stone, serving for the paving of gardens and parks, paths, etc., is proposed. So that the paving stone laid out in a continuous system gives the best possible natural appearance, practical handling is guaranteed and strength is provided to an unrestricted degree, the side surfaces of the paving stone are designed as plane surfaces, but the transitional surfaces between the side surfaces and the upper surface are rounded and designed in such a way that the limiting line which is visible when seen from above is curved. The lateral limiting line between the transitional surface and the plane side surface is also shaped as a curved line, that is to say the corners are drawn down. For universal use, there are various construction sizes matching one another and special corner stones or curved stones which allow space-saving laying in a composite structure.
