Abstract

Abstract When laying solid curbstones a ditch must be dug into which the curbstone is placed. The ditch is then filled in order to support the curbstone. The ditch-digging is eliminated according to the present invention in that a continuous shell (1) with coating (2) of stone is placed on a supporting surface and anchored by a rod (4) which passes through a hole in one side wall, through a hole in the bottom and penetrates into the support surface.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 207 words
In a assembly for use in forming an edging along the ground, a preformed curbstone comprising an elongate hollow shell having a bottom wall engageable with the ground, laterally spaced side walls extending upwardly from said bottom wall, and a top wall portion extending between said side walls vertically above said bottom wall to define an internal cavity, a pair of aligned holes, an elongate anchor rod having a ground penetrating point and an upper end with a stop thereon and engageable with said one side wall for mutual retention of said rod in said aligned holes and said curbstone on said rod, one of said aligned holes being disposed in said bottom wall outwardly spaced from one side wall and the second of said aligned holes being disposed in said one side wall vertically spaced above said bottom wall and diagonally aligned with said one hole across said shell for positioning of said elongate anchor rod within and through both holes and at an angle into the ground for an engagement of the rod with said one side wall and said bottom wall of said shell, said engagement providing stable positioning and anchoring of said curbstone to the ground and preventing laterally shifting of said curbstone.
