GRASS PAVER
The invention relates to a grass paver with a rectangular lattice-like body which is formed by intersecting transverse struts and longitudinal struts which form at least one grid opening, wherein the transverse struts project beyond the longitudinal struts and the longitudinal struts project beyond the transverse struts, wherein corners of the grass paver are each formed by a leg of one of the transverse struts and a leg of one of the longitudinal struts. Here, at least one transverse strut and/or at least one longitudinal strut has a zigzag-shaped and/or wavy profile when seen in plan view.
This application is a continuation of International Application No. PCT/EP2007/010010 filed Nov. 20, 2007, and claims the benefit under 35 U.S.C. §119(a)-(d) of German Application No. 10 2006 054 852.3 filed Nov. 20, 2006, the entireties of which are incorporated herein by reference.
FIELD OF THE INVENTIONThe invention relates to a grass paver.
BACKGROUND OF THE INVENTIONDE 20 2004 009 898 U1 discloses a grass paver which has a lattice-like body which is formed by intersecting transverse struts and longitudinal struts which form at least one lattice opening, wherein the transverse struts project beyond the longitudinal struts and the longitudinal struts project beyond the transverse struts, wherein corners of the lattice paver are each formed by a leg of one of the transverse struts and a leg of one of the longitudinal struts. The disadvantage of such grass pavers is that, regardless of whether there is any variation in the laying technique between, for example, a running bond and cross-joint bond and/or a change in the orientation, they give a virtually unchanged appearance to a paver arrangement composed of a plurality of identical grass pavers.
SUMMARY OF THE INVENTIONThe object on which the invention is based is to develop a grass paver by means of which paver arrangements having different structures can be produced, with the result that identical grass pavers can be used, for example, to construct driving areas, parking areas or walking areas having a different appearance.
The grass paver according to the invention comprises at least one transverse strut and/or at least one longitudinal strut which have a zigzag-shaped and/or wavy profile when seen in plan view. It is possible by selecting different laying techniques and/or different orientations of the grass pavers for paver arrangements having different geometries to be produced with such grass pavers. Therefore, the essence of the invention is a grass paver which can be used for paver arrangements having different intended uses. Such a grass paver allows optimum cohesion between the grass pavers of the paver arrangements having different intended uses, since identical grass pavers optimally tailored to one another are used. Furthermore, such a grass paver makes the planning of building projects considerably easier, since only the requirement for a certain area has to be calculated first of all and the intended use or the appearance of an area can be determined at a later time.
Furthermore, the invention provides for at least one of the corners of the grass paver to be formed by legs of different length. This makes it possible to further vary the appearance of paver arrangements in which the grass pavers are laid with different laying techniques and/or orientations.
Provision is made according to the invention for at least one of the transverse struts and/or longitudinal struts to be provided, at an underside, with a tunnel-like recess which extends in the direction of the transverse strut or the longitudinal strut and which opens at the lateral ends of the transverse strut or longitudinal strut. This makes it possible, for example, to lay electrical lines and/or irrigation lines continuously over the paver arrangement.
Furthermore, the invention provides for at least one strut, and in particular the longitudinal struts and/or the transverse struts, to be formed with a trapezoidal cross section. A tunnel-like recess can be easily integrated in such struts without substantially weakening the strut. Furthermore, compressive loads and tilting moments can be readily transmitted or absorbed by a downwardly widening strut.
The invention also provides for the longitudinal struts to be designed with a greater height than the transverse struts and to be allowed to project beyond the transverse struts at an underside of the grass paver. As a result, higher vehicular traffic loads can be achieved for the individual grass pavers, since the grass paver also interacts positively with the ground and therefore can better take up shear loads in particular.
Provision is made according to the invention to design the grass paver with a square grid when seen in plan view. As a result, a change in orientation of the grass paver in 90° steps is possible even within a paver arrangement. Such a change in orientation of the grass paver increases the number of laying variants.
According to the invention, provision is made to arrange undersides of the transverse struts and longitudinal struts of the grass paver in an upper bearing plane and a lower bearing plane. As a result, any floating of the grass paver on the ground is better prevented, because the grass paver penetrates the ground by way of individual struts.
The invention provides a paver arrangement having grass pavers, in which arrangement a grass paver, which is surrounded by six or eight grass pavers, forms together with these adjacent grass pavers at least two lattice openings which differ from one another in their shape and/or area, wherein at least one of these lattice openings differs from a rectangle. A completely different visual impression can be achieved with such paver arrangements when changing the laying technique and/or the alignment of the grass pavers with identical grass pavers.
Finally, the invention provides a further paver arrangement composed of grass pavers, in which arrangement a grass paver, which is surrounded by six or eight grass pavers, forms together with these adjacent grass pavers at least three lattice openings which differ from one another in their shape and/or area, wherein at least two of these lattice openings differ from a rectangle. A completely different visual impression can also be achieved with such a paver arrangement when changing the laying technique and/or the alignment of the grass pavers with identical grass pavers.
Further details of the invention are described in the drawing by way of schematically illustrated exemplary embodiments.

In
In the central subarea II, the grass paver 1 marked by a thick contour line is surrounded by six grass pavers 101 to 106. Around the laterally closed lattice opening 8 of the grass paver 1, lattice openings 9a to 9h are closed by the adjacent grass pavers 101 to 106. These lattice openings are partially congruent to one another. In a right subarea III, the grass paving stones 1 are each rotated by 90° with respect to the grass paving stones 1 of the left and central subareas I, II. Overall, the different laying techniques or different orientations shown in
The grass pavers described are preferably embodied as paving stones and produced from concrete. However, according to a variant embodiment, provision is also made to configure the grass pavers from plastic or other suitable materials or combinations of materials.
The invention is not limited to exemplary embodiments which have been depicted or described. Rather, it encompasses developments of the invention within the scope of the claims. According to a variant embodiment which has not been depicted, provision is also made for paving stones embodied as grass pavers which have a rectangular grid when seen in plan view and in which the grid length and the grid width are dimensioned differently.
