Traversing stone for traversing arrangement on underneath construction, has front side including two portions forming partial planar sections having slope gradually increasing towards front side

摘要

The stone (101) has cuboid outer sides (105, 106), a flat upper surface (108) with respect to an opposing base (102), a front side (103), and a back side (104). A sloping contact surface (110) is provided in the front side. The front side includes a portion with a radius of curvature, and another portion between the former portion and the upper surface, where a radius of curvature of the latter portion is smaller than that of the former portion. The portions form partial planar sections having a slope gradually increasing towards the front side. An independent claim is also included for a traversing arrangement on an underneath construction.
