Abstract

An essentially quadrate paving stone having a corresponding base block ( 21 ) is provided on all four side surfaces ( 25, 26 ) with flange-like, upright spacers ( 22 ) which are spaced apart from each other at intervals corresponding approximately to the width of the spacers, making it possible for them to make an interlocking connection with adjacent shaped paving stones of the same type. Furthermore, the bottom side ( 24 ) of the paving stone features a number of transverse, gutter-like depressions resulting in the formation of ribs between these depressions. This creates an additional dentification, or anchoring, in the bed surface of the installed paving stones.

Claims (35)

1. A ground cover laid on a pavement bed, comprising paving stones ( 20 , 44 , 45 , 46 , 48 , 49 ) each having an essentially flat top side ( 23 ), a bottom side ( 24 ), four upright sides, spacers ( 22 ) arranged continuously around the four upright sides ( 25 , 26 , 28 ) in a regular grid pattern ( 39 ), and shifting prevention devices on the four upright sides ( 25 , 26 , 28 ) and the bottom side, wherein:

a) the spacers ( 22 ) of one of the paving stones are arranged to engage in an offset manner to the spacers ( 22 ) of a neighboring paving stone;

b) the shifting prevention devices on the bottom side ( 24 ) are a plurality of depressions ( 56 ) that interlock with the pavement bed ( 58 ) and that extend continuously from one of the upright sides ( 25 , 26 , 28 ) to another of the upright sides ( 25 , 26 , 28 );

6. The ground cover according to claim 2 , wherein the distance between the two adjacent spacers ( 22 ) arranged on one of the four upright ( 25 , 26 , 28 ) corresponds approximately to the width of the spacer ( 22 ).

7. The ground cover according to claim 1 , wherein all of the spacers are identical in dimension and shape.

8. The ground cover according to claim 1 , wherein all of the spacers extend essentially across the entire height of the paving stones, proceeding from the bottom side ( 24 ) and ending at a slight distance from the top side ( 23 ).

9. A ground cover laid on a pavement bed, comprising paving stones ( 20 , 44 , 45 , 46 , 48 , 49 ) each having an essentially flat top side ( 23 ), a bottom side ( 24 ), four upright sides, spacers ( 22 ) arranged continuously around the four upright sides ( 25 , 26 , 28 ) in a regular grid pattern ( 39 ), and shifting prevention devices on the four upright sides ( 25 , 26 , 28 ) and the bottom side, wherein:

a) the spacers ( 22 ) of one of the paving stones are arranged to engage in an offset manner to the spacers ( 22 ) of a neighboring paving stone and one of the spacers ( 22 ) of each of the four upright sides is placed directly at an upright corner or edge of the paving stone and another one of the spacers ( 22 )is arranged at an opposite upright corner or edge of the paving stone and is separated from the opposite upright edge by a space corresponding to the distance between two adjacent spacers ( 22 );

b) the shifting prevention devices on the bottom side ( 24 ) are a plurality of depressions ( 56 ) that interlock with the pavement bed ( 58 ) and that extend continuously from one of the upright sides ( 25 , 26 , 28 ) to another of the upright sides ( 25 , 26 , 28 ) and the depressions ( 56 ) are separated from one another by a space that corresponds approximately to one grid unit ( 42 ), spaced at equal intervals from one of the four upright sides ( 26 );
