Description

"Grass paver"

The invention relates to a grass paver according to the preamble of claim 1.

From DE 20 2004 009 898 Ul a lawn paver is known, which has a lattice-like body which is formed by crossing transverse struts and longitudinal struts, which form at least one grid opening, wherein the cross struts protrude beyond the longitudinal struts and the longitudinal struts protrude beyond the cross struts, wherein corners of the grass paver are each formed by a leg of one of the cross struts and a leg of one of the longitudinal struts. A disadvantage of such grass pavers is that, regardless of a variation of the laying technique between, for example, runners Association and Kreuzfugenverband and / or a change in orientation, give a nearly unchanged appearance of a stone arrangement of several same lawn pavers.

The invention has for its object to develop a grass paver with which stone arrangements can be produced with different structure, so that with the same lawn pavers, for example, driving surfaces, parking areas or walking surfaces are created with different optics. This object is achieved on the basis of the features of the preamble of claim 1 by the characterizing features of claim 1. In the dependent claims advantageous and expedient developments are given.

The grass paver according to the invention comprises at least one transverse strut and / or at least one longitudinal strut, which has a zigzag-shaped and / or corrugated course in plan view. By choosing different laying techniques and / or different orientation of grass pavers stone arrangements with different geometry can be produced with such grass pavers. Core of the invention is thus a lawn paver, which can be used for stone arrangements with different usage. Such a grass paver allows optimal cohesion between the grass pavers of the stone arrangements with different usage, since the same, optimally matched lawn pavers are used. Furthermore, such a grass paver greatly facilitates the planning of construction projects, since initially only the need for a certain area is to be calculated and the

Usage determination or the appearance of a surface can be set at a later date.

Furthermore, the invention provides for at least one of the corners of the grass paver to be formed by different long legs. As a result, the appearance of stone arrangements in which the grass pavers are laid with different laying technique and / or orientation can be further varied.

According to the invention, it is provided to provide on at least one of the transverse struts and / or longitudinal struts on an underside a tunnel-like recess extending in the direction of the transverse strut or longitudinal strut, which extends to the lateral ends of the transverse strut or longitudinal strut opens. This makes it possible to continuously lay over the stone arrangement, for example, electrical lines and / or irrigation lines.

Furthermore, the invention provides, trapezoidal form at least one strut and in particular the longitudinal struts and / or the cross struts in cross section. In such struts, a tunnel-like recess can be easily integrated without significantly weakening the strut. Furthermore, pressure loads and tilting moments can be passed on or intercepted well by a strut that widens downwards.

The invention also provides to design the longitudinal struts with a greater height than the cross struts and to let them protrude on an underside of the grass paver over the cross struts. As a result, higher driving loads can be achieved for the individual grass paver, since the grass paver also interacts with the substrate in a form-fitting manner and can therefore absorb shear loads better, in particular.

According to the invention, it is provided to design the grass paver in plan view with a square grid. As a result, a change in the orientation of the lawn paver in 90 ° increments is possible even within a stone arrangement. Such a change in the orientation of the grass paver increases the number of laying variants.

According to the invention, it is provided to arrange undersides of the transverse struts and longitudinal struts of grass paver in an upper support level and a lower support level. As a result, a swimming of grass paver on the ground better prevented because - A -

the grass paver with individual struts penetrates into the underground.

The invention provides a stone arrangement with grass pavers according to claim 1, in which a lawn pawn surrounded by six or eight grass pavers forms at least two grid openings deviating in shape and / or area from these adjacent grass pavers, at least one of these grid openings being a rectangle differs. With such stone arrangements is in a change in the laying technique; and / or the alignment of the grass pavers with the same grass pavers a completely different visual impression achievable.

Finally, the invention provides a further stone arrangement of grass pavers according to claim 1, in which a grass paver surrounded by six or eight grass pavers forms at least three grid openings deviating in shape and / or area from these adjacent grass pavers, at least one two of these grid openings deviate from a rectangle. Even with such a stone arrangement a completely different optical impression can be achieved with a change in the laying technique and / or the orientation of the grass pavers with the same grass pavers.

Further details of the invention are described in the drawing with reference to schematically illustrated embodiments.

FIG. 1a shows a plan view of a first grass paver 1 according to the invention. The grass paver 1 has a body 2, which consists of two transverse struts 3, 4 and two longitudinal struts 5, 6. These form a grid 7 with each other, which has a laterally closed grid opening 8. The struts 3 to 6 are arranged similar to a double cross or a so-called diamond sign. The intersecting transverse struts 3, 4 and longitudinal struts 5, 6 are each with legs 3a, 3b, 4a, 4b, 5a, 5b, 6a, 6b laterally beyond each other. Between these legs 3a to 6b are more grid openings 9a to 9h. Four corners 10a to 10d of the lawn grid brick 1 having a square grid RQ in plan view are formed by two legs 4a, 5a and 6a, 4b and 3b, 6b and 5b, 3a, respectively. The cross struts 3, 4 and the longitudinal struts 5, 6 have in plan view of an upper side 14 of the grass paver 1 each have a zigzag course corresponding to the zigzag lines Z3 to Z6. The zigzag lines each have two break points K1, K2. At lateral ends 11 of the transverse struts 3, 4 or longitudinal struts 5, 6 are each two spacers 12, 13 arranged for toothing with an adjacent grass lawn stone, not shown here. The grass paver 1 has a grid width RB and a grid length RL, wherein RB = RL applies to the grass paver 1 shown in FIG. 1a. For the lateral ends 11 of the transverse struts 3, 4 or longitudinal struts 5, 6 and the spacers 12, 13 arranged on these, it is true that these are arranged point-symmetrically to a center M of the grass paver 1. The grass paver 1 has four notches 15 on its upper side 14, which give the lawn paver 1 the appearance of four individual stones.

FIG. 1b shows a section through the grass paver 1 shown in FIG. 1a along the section line 1a-1a shown in FIG. 1a. The cross strut 3 recognizable in the sectional view and the longitudinal strut 5 recognizable in the sectional view each have identical heights H3 and H5.

FIG. 2 shows a top view of a stone arrangement 16, in which the grass paver 1 shown in FIG. 1 a is laid in a cross joint KFV. For a better understanding of one of the illustrated grass pavers 1 is indicated by hatching. Together with adjacent grass pavers 101 to 108, a further eight laterally closed grid openings 9a to 9h are formed by the grass paver 1 around its laterally closed grid opening 8. Of these, the grid openings 9a, 9c, 9e and 9g in plan view as Squares formed. The grid openings 9b, 9d, 9f and 9h each form a rhombus in plan view.

In FIG. 3, the stone arrangement 16 known from FIG. 2 is still shown without notches (see FIG. 1 a) in order to facilitate the overview. The illustrated Kreuzfugenverband KFV has between the grass pavers 1 exclusively cross joints KF.

FIG. 4 shows a further stone arrangement 16, which is composed of grass pavers 1 according to FIG. In contrast to Figure 2, the grass pavers 1 ii are laid in this stone arrangement 16 a so-called runners Association LVB. That adjacent rows of stones Rl to R3 are each offset by half a grid width RB to each other. The highlighted by a hatch grass paver 1 forms around its laterally closed grid opening 8 around together with six adjacent grass pavers 101 to 106 another eight laterally closed grid openings 9a to 9h. Here, the grid opening 9 e is designed in plan view as a square. The grid openings 9c, 9d, 9f and 9g are designed as congruent quadrilaterals. The grid openings 9a, 9b and 9h are formed by further non-congruent polygons.

In FIG. 5, the rotor assembly LVB shown in FIG. 4 is again shown without notches analogous to FIG. 3 (see FIG. 1a). In the stone arrangement 16 shown in FIG. 5, the T-joints TF resulting from the laying in the runner association LVB between the individual grass pavers 1 are clearly recognizable.

In the figure 6a, a second embodiment of a grass paver 1 is shown in plan view. Basically, reference is made here to the description of Figure Ia. In contrast to the grass paver shown in FIG. 1a extend transverse struts 3, 4 or longitudinal struts 5, 6 of the grass paver 1 shown in Figure 6a along zigzag lines Z3 to Z6, which each have three break points Kl to K3. The grass paver has four short legs KS with legs 4b, 3b, 6b and 5b and four long legs LS with legs 3a, 4a, 5a and 6a. A first corner 10a of the grass paver 1 is formed by two long legs LS and 5a, 5a. A diagonally opposite corner 10c is formed by two short legs KS and 3b, 6b. Two further diagonally opposite corners 10b, 10d are formed by a respective short leg KS or b4 or 5b and in each case a long leg LS or 6a or 3a. With regard to its leg lengths, the grass paver 1 is not point-symmetrical with respect to a center point M. By means of notches 15, the grass paver 1 is subdivided into four congruent cross-shaped partial bodies TK1 to TK4 of the same orientation.

FIG. 6b shows a section through the grass paver 1 shown in FIG. 6a along a section line VIa-VIa. In the sectional view, the transverse strut 3 and the longitudinal strut 5 can be seen, which have uniform heights H3 and H5.

FIGS. 7a and 7b show a third variant of a grass paver 1 according to the invention in side view and top view. The grass paver 1 has two transverse struts 3, 4 and two longitudinal struts 5, 6. The transverse struts 3, 4 run along wavy lines or serpentine lines S3, S4. The longitudinal struts 5, 6 are straight and are trapezoidal in section and in side view, respectively. Furthermore, the transverse struts 5, 6 at the lower sides U5, U6 each have a tunnel-like recess T5, T6, which for the laying of electrical lines or

Irrigation lines is provided. In contrast to the grass pavers shown in FIGS. 1a and 6a the grass paver 1 shown in FIGS. 7a and 7b has different heights H4 and H5, H6 with respect to their cross struts 3, 4 and longitudinal struts 5, 6, respectively. The transverse struts 3, 4 and longitudinal struts 5, 6 form a planar upper side 14 of the grass paver 1. To an underside 17 of the grass paver 1, the longitudinal struts 5, 6 project beyond the cross struts 3, 4. As a result, lower sides 18 or 19 of the transverse struts 3, 4 or the longitudinal struts 5, 6 of the grass paver 1 lie in two different contact planes AE1 and AE2 (see FIG. 7a). This shear protection in the gravel bed and / or sand bed and / or ground bed is particularly effective, since the grass paver 1 is supported on lying at different levels earth layers, and thus a gradual smoothing of the ground is made difficult by the grass paver. According to a variant of the invention, not shown, at least the underside 18 of the transverse struts 3, 4 or the bottom 19 of the longitudinal struts 5, 6 are provided with additional ribs. As a result, the respective support level to a thrust protection level, which further increases the support of the lawn paver on or in the ground against shear forces.

FIG. 7c shows a stone arrangement 16 which is formed from grass pavers 1 which respectively correspond to the grass paver shown in FIGS. 7a and 7b. Within the stone arrangement 16, the grass pavers 1 are laid in a different orientation. An indicated by hatching grass paver 1 is surrounded by eight grass pavers 101 to 108. The grid openings 9a to 9h are closed by the adjacent grass pavers 101 to 108 around the laterally closed grid opening 8 of the grass paver 1. Here, the grid openings 9a, 9b, 9d, 9c, 9f and 9h in plan view are congruent to each other. Furthermore, the grid openings 9c and 9g are congruent with each other. FIG. 8 a shows a plan view of a fourth grass paver 1.

FIG. 8b shows a further stone arrangement 16, which is constructed from grass pavers 1, which correspond to the grass paver shown in FIG. 8a. In a left partial surface I of the stone arrangement 16, the grass pavers 1 are arranged in a Kreuzfugenverband KFV. In a middle partial surface II of the stone arrangement 16, the grass pavers 1 are arranged in a rotor assembly LVB. Depending on the laying technique - Kreuzfugenverband or runners association - arise in plan view different geometric shapes of the grid openings 9a to 9h, which are formed by cooperating grass pavers 1. This also creates a different overall impression, which does not result as in conventional paving stones through the joint pattern, but by the geometries of the grid openings 9a to 9h. In the left partial area I of the marked by a strong contour line grass paver 1 of eight grass pavers 101 to 108 is surrounded. To the laterally closed grid opening 8 of the grass paver 1 around are closed by the adjacent grass pavers 101 to 108 grid openings 9a to 9h. Here, the grid openings 9b, 9d, 9f and 9h in plan view are congruent to each other. Furthermore, the grid openings 9c and 9g are congruent with one another and finally the grid openings 9a and 9e are congruent.

In the middle partial area II of the marked by a strong contour line grass paver 1 of six grass pavers 101 to 106 is surrounded. To the laterally closed grid opening 8 of the grass paver 1 around are closed by the adjacent grass pavers 101 to 106 grid openings 9a to 9h. These are partially congruent to each other. In a right sub-area III, the turf paving stones 1 are opposite to the Lawn paving stones 1 of the left and middle part surface I, II rotated in each case by 90 °. On the whole, different areas of application result from the different laying techniques or different orientations shown in FIG. 8b. Thus, with a single type of grass paver stone arrangements with different optics can be created. This allows the construction of traffic areas with different destination such as carriageway, footpath, bike path or parking lot from the same grass pavers. Here, the different appearances are determined by the openings that result between adjacent lawn pavers in the stone arrangement.

FIG. 9 a shows a plan view of a fifth grass paver 1. This has two mutually parallel S-shaped cross braces 3, 4 and two mutually parallel straight longitudinal struts 5, 6. The lateral ends 11 of the transverse struts 3, 4 and the longitudinal struts 5, 6 are arranged point-symmetrical to a center M of the grass paver 1.

FIG. 9b shows another stone arrangement 16, which is constructed from grass pavers 1, which correspond to the grass paver shown in FIG. 9a. These are laid in different orientations and in different laying techniques.

FIG. 10 a shows a plan view of a sixth grass paver 1. This has two S-shaped curved transverse struts 3, 4 and two mutually parallel straight longitudinal struts 5, 6. The lateral ends 11 of the transverse struts 3, 4 and the longitudinal struts 5, 6 are arranged point-symmetrical to a center M of the grass paver 1. In contrast to that shown in FIG. 9a Rasengitterstein are the S-shaped cross braces 3, 4 arranged mirror-symmetrically to a mirror plane SE.

FIG. 10b shows another stone arrangement 16, which is constructed from grass pavers 1, which correspond to the grass paver shown in FIG. 10a. The stone assembly 16 is laid as a so-called Kreuzfugenverband KFV.

FIG. 10c shows a further stone arrangement 16, which is constructed from grass pavers 1, which correspond to the grass paver shown in FIG. 10a. The stone assembly 16 is laid as a so-called runners Association LVB.

The described Rasengittersteine are preferably designed as paving stones and made of concrete. According to one embodiment, however, an embodiment of grass pavers made of plastic or other suitable materials or material combinations is provided.

The invention is not limited to illustrated or described embodiments. Rather, it includes developments of the invention within the scope of the patent claims.
