Stein, in particular paving stone and made of such stones pavement

The invention "relates to a stone, in particular a paving stone with zigzag-shaped teeth on the side surfaces to be brought into engagement.

The object of the invention is, while maintaining the with such known stones to achieve good association in paving the resulting disadvantages Transport, namely to avoid the risk of the stone corners breaking off.

According to the invention, this object is to be achieved in that the stone has contact surfaces at its corners that are parallel for the longitudinal and transverse extension of the stone at the level of half the tooth depth of the zigzag-shaped toothing.

In the case of stones whose end faces correspond to half the length of their long sides, the Invention of the stone in a central section instead of the third toothing have flat AnI3geflachen that are parallel to the longitudinal extension of the stone at half the depth of the tooth.

In a further embodiment of the invention, the protruding teeth run into the road surface with a sloping incline the stones out.

The invention is based on an exemplary embodiment in FIG Description explained below and shown in the drawing näner; are in it

Pig. 1 is a plan view of a rope of the paving with 3 stones in the so-called elbow bandage,

Pig. 2 shows a side view of one of the upright side longitudinal surfaces of a stone.

After Pig. 1, identical stones 1, 2, 3 are put together in a pavement. Each stone points on its long sides 6 tooth groups 4 and 5. Each tooth runs vertically from the lower surface b to the surface 7 of the stone, into which the tooth ends with an oblique slope 15. The same is true for the teeth 9 on the face of the stone.

Each stone has contact surfaces 12 and 1p at its corners, instead of the toothing parallel to the longitudinal and transverse extension of the stone at half the tooth depth of the zigzag-shaped Toothing run, so meet at right angles. So the corners have the appearance of a normal rectangular stone with smooth sides. Opposite to the teeth are the contact surfaces springing back to the Tooth tips arranged, which prevents crumbling during transport, so that stones according to the embodiment according to the invention are already superior to commercially available stones with smooth side surfaces with regard to this criterion.

For stones that have front sides for an offset paving, whose width is half as large as the long side, are in a central section of the long sides instead of the toothing flat contact surfaces 14 are provided on both longitudinal sides, the

parallel to the longitudinal extension of the stone at the height of half Tooth depth run between groups of teeth 4 and 5. Against these contact surfaces lay the corners of two pushed together stones 1 and 2 of the adjacent row with their contact surfaces 13. In this form, the Yerband interlocks seamlessly, with the tips of each tooth are located in the adjacent recesses of the toothing.

In the assembled bandage, the width of the eye is b between adjoining stones about 2 mm each. Towards the surface 7, the width of the gap increases as a result the bevels 15 to a size a of, for example, 16 mm between the boundary lines 10 and 11 of the road surface 7 “These widened eyes can be covered with dust or sand can be filled in, so that despite the interlocking there is a flat colorway surface.

The distance c between the boundary line 11 and the flat one Front side 13 of the corners is slightly more than half of the eye width a on the surface of the road surface. The distance e between a side surface 13 'and the contact surface 14 of the opposite one located in the central area Side offset applied stone and thus between 2 parallel side surfaces 13 corresponds in practice to the normal stone dimension of currently 104 mm, if a length f of 210 mm is assumed.
