Group of paving stones

The invention relates to a group of paving stones with circumferential teeth on the outer sides of the group and whose individual stones have joint spacers and an upper bevel.

Paved surfaces have the task of distributing loads in such a way that there is no shifting, settling or even cracking of the paving stone surface.

They should be able to be laid optimally and create a varied image when laid. Furthermore, the rainwater that accumulates should be drained into the subsoil.

It is known that composite stones with a wide variety of shapes and interlockings are used for paving surfaces. The paving stones have a regular all-round interlocking, which then determines the joint pattern of a laid surface and is reflected in it. These are paving surfaces with identical stones that are only laid in the beginning or side areas with precisely fitting additional stones. The stones have spacers so that the rainwater that accumulates can be drained through the joints into the subsoil. The paving stones are designed so that they can be laid with a laying machine. However, paving stone surfaces laid with them only offer one design option.

—&Oacgr;—

The recurring single paving element therefore appears boring in the surface.

Rectangular stones are also known, which have different formats and thus convey an attractive image of the paving stone surface. The paving stones are manufactured in rectangular paving stone sets, and when laid by machine, continuous joints arise from paving stone set to paving stone set, which impairs the bonding effect.

Furthermore, large-format paving stones are known on the top of which one or more dummy joints are pressed with the stamp. These give an attractive image of a surface laid in this way. However, since these are large-format paving stones, the rainwater that accumulates can only be drained away in the area of the real joints between the stones.

The invention is based on the task of creating a paving stone surface that has a good bonding effect and can be optimally laid with a laying device or by hand. Furthermore, the paving stone surface should guarantee optimal drainage of surface water into the subsoil and convey a visually appealing image.

These objects are achieved with the paving stone groups described in the claims.

The invention will now be explained in more detail with reference to the drawings.

Fig. 1 shows a possible embodiment of a group of paving stones according to the invention.

The assembled group (1), which describes an essentially rectangular floor plan, has the interlocking on the group's outer sides (2,3,4,5) with projections (6a) and precisely fitting recesses (7a). The individual stones (8,9 and 10) viewed on their own do not show any possibility of interlocking. The individual stones (8,9,10) of a group (1) are differently shaped inside the group, so that the joint pattern inside the group has a free line (11,12).

All corners (24) of the individual stones (8,9 and 10) are rounded.

Here a group (1) of three individual stones (8, 9 and 10) with an essentially rectangular floor plan is shown. However, a much freer line (11, 12) can also be chosen, as well as a different number of individual stones. The smallest group (1) consists of two individual stones.

The adjacent group outer sides (2,3 and 4,5) have unequally shaped projections (6a) and recesses (7a).

The upper group outer side (2) has two outer recesses (7a) and a central projection (6a) and the adjacent right group outer side (3) has an outer projection (6a) and an outer recess (7a). The opposite sides (4,5) run parallel to this.

Fig. 2 shows another group (1) of paving stones according to the invention. It consists of only two individual stones (14 and 15). The upper group outer side (2) also has two outer recesses (7a) and

-9-

a central projection (6a) and the opposite lower group outer side (4) runs parallel to it. The right group outer side (3) has a projection (6a) in the lower area up to about halfway and a recess (7a) in the upper area. The opposite left group outer side (5) runs in a mirror image of this. All projections (6a) and recesses (7a) of the group outer sides (2,3,4 and 5) are evenly shaped so that each projection (6a) fits into a recess (7a). The line (27) runs parallel to the group outer side (3) and begins at the starting point (28) of the left outer recess (7a) of the group outer side (2), so that a narrower single stone (14) with a taper (29) and a wider, essentially square single stone (15) with projections (6b) and recesses (7b) are created.

Fig. 3 shows another group (1) of paving stones according to the invention, which is based on the same construction principle as Fig. 2. The narrower single stone (14) is divided at the beginning (30) of the taper (29) by a line (31) into a small square stone (32) and a large square stone (33), so that the group (1) consists of three single stones (15,32,33).

Fig. 4 shows the mirror image of a group (1) of paving stones according to Fig. 3.

In Fig. 5, several groups (1) of the same external shape are assembled to form a substantially rectangular paving stone set (13) in such a way that different joint patterns are present from group (1) to group (1).

However, this arrangement is only useful for machine-laid paving stone sets (13), since the large number of

-10-

Differently shaped individual stones are difficult to lay by hand.

In order to make the outer group grid less conspicuous, it is important that adjacent group outer sides (1,2 and 4,5) have unevenly shaped projections (6a) and recesses (7a).

A paving stone set (13) is manufactured using only one mold and is laid as a whole on the construction site using a laying machine. Since the individual groups (1) have the same external shape, the paving area widths and lengths can be laid as desired in the grid dimensions of the groups (1). Even a paving area finish that is below the grid dimensions is possible thanks to the smaller individual stones incorporated.

However, to make laying by hand easier, it is also possible to distribute two or three groups (1) of paving stones with different joint patterns inside the group, but with the same external shape, irregularly in the paving stone set (13). The different design of the individual groups distracts the image from the external group grid, but does not completely eliminate it.

Fig. 6 shows another paving stone set (13) with paving stone groups (1) of Fig. 3 and 4 as well as individual stones (15,32,33) of these paving stone groups (1), which are assembled to form an essentially rectangular paving stone set (13). The paving stone groups (1) in the paving stone set (13) are shown with different hatching. The individual stones are not hatched. It is clear that the paving stone groups (1) must be arranged rotated by 180° or 90° in order to achieve mutual interlocking, or a horizontal

-11-

-11-

or vertical offset can be created. The group (1) is therefore unclear to the observer of a laid paving stone surface. The individual stones (15,32,33) incorporated into the paving stone set (13) support this effect.

In the paving stone set (13), a small square stone (32) and a large square stone (33) are each located on two adjacent paving stone set outer sides (36,37), and on the paving stone set outer sides (34,35) lying parallel to them, at the same height, there is a wider, essentially square single stone (15) with projections (6b) and recesses (7b). The significance of this measure is explained in Fig. 1 and 8.

Fig. 7 shows the laying principle for paving stone inserts (13) according to Fig. 6.

For the first paving stone set (13) laid by machine, located at the top left, the small square stone (32) and the large square stone (33) are removed from the paving stone set (13) by hand. After the paving stone set (13), shown at the bottom left, has been placed on the first paving stone set (13), the paving stone (15) of the lower paving stone set (13) is again removed by hand and laid with a quarter turn into the free opening of the first paving stone set laid, shown at the top (13). The previously removed individual stones (32,33) are then laid in the lower paving stone set (13) in the precisely fitting, free openings.

This option of interlocking the paving stone inserts is available on all paving stone insert outer sides (34, 35, 36 and 37). For better clarity, the individual paving stone inserts (13) are shown at a distance from each other.

-12-

Fig. 8 shows a paving stone surface that was laid according to the laying principle of Fig. 7. It is clear that the outside of the paving stone inserts, which are marked by the arrows, are now interrupted by the individual stones (15), so that no system is visible anymore. Laying by hand is easy thanks to the grid of the paving stone groups and the fact that there are only three individual stones (15,32,33).

Fig. 9 shows another group (1) of paving stones according to the invention.

The outer group shape is the same as in Fig. 1. The joints in a group (1) are designed so that a free line (16) starting from the upper group outer side (2) leads to the right group outer side (3) and a free line (17) starting from the left group outer side (5) leads to the lower group outer side (4). The line start point (18) of the upper group outer side (2) is opposite the line end point (19) of the lower group outer side (4), and the line start point (20) of the left group outer side (5) is opposite the line end point (21) of the right group outer side (3).

Both free lines (16,17) can also intersect. However, here a possibility is shown that both free lines (16,17) do not intersect. The resulting center stone (22) is undivided or divided by one or more free lines (23).

Fig. 10 shows several groups (1) of paving stones according to the invention as shown in Fig. 9 which are assembled to form another paving stone set (13).

No change was intentionally made to the joint pattern in the individual groups (1).

You can see how the free lines extend beyond the group edge

-13-

continue unhindered into the neighboring groups (1). It appears as if a second grid has been laid over the existing external joint grid of the groups (1) by the free line layout.

However, it is also possible that only the free lines (16,17) inside the group (1) change from group (1) to group (1) in the paving stone set (13), but not the position of the line start points (18,20) and the line end points (21,19).

Fig. 11 and 12 after Fig. 10 show just two examples of many possibilities of how the most diverse effects can be achieved by incorporating colored stones using this double grid.

Fig. 13 shows how paving stone sets (13) from Fig. 5, 6 and 10 can be combined with one another. The paving stone sets (13) from Fig. 5 and 10 can be easily arranged one above the other or next to the other. Each paving stone set (13) engages with the next paving stone set (13) with its circumferential teeth.

It is now clear that a machine-laid paving stone surface also has a good bonding effect between the individual paving stone sets (13).

Furthermore, the different design of the individual stones creates a varied paving stone surface.

Only a mold for machine production is sufficient to produce either a paving stone surface according to Fig. or Fig. 10 as an independent paving stone surface.

-14-

However, if paving stone sets (13) of Fig. 5 and 10 are used in combination, the greatest possible design variety for paving stone surfaces can be achieved.
Paving stone sets (13) according to Fig. 6 must be connected laterally to paving stone sets (13) according to Fig. 5 and 10.

Fig. 14 shows another group (1) of paving stones according to the invention.

The external group shape is the same as shown in Fig. 2, 3 and 4. The joint pattern inside the group is identical or similar to that shown in Fig. 9.

For all individual stones (8,9,10,14,15,22,223,25,253,26, 26a,32 and 33) all corners (24) are rounded.

This measure causes the joint in this area to widen and leads to better rainwater permeability of the paving surface.

In Fig. 15 you can see how paving stone groups (1) according to Fig. 3, 4 and 14 can be easily combined with one another due to their similar external group design.

By incorporating coloured individual stones (22a, 25a and 26a) as shown in Fig. 14, a wide variety of effects can be incorporated into a paving stone surface.

Paving stone sets (13) made up of paving stone groups as shown in Fig. 14 can also be laid without any problem in their entirety like paving stone sets (13) as shown in Fig. 6.

The outer sides of the plaster stone inserts have the same grid as shown in Fig. 6 and can therefore interlock with each other.

-15-

Due to the previously described laying principle for paving stone sets (13) according to Fig. 7, a laid paving stone surface no longer shows a laying pattern. Furthermore, the interlocking from paving stone set (13) to paving stone set (13) is increased.

Laying the tiles by machine or by hand is not a problem.

The rounded corners (24) of the individual stones (15,223,258,263,32,33) unseal the paving surface and ensure optimal water drainage into the subsoil without reducing the user properties of the piastres stone surface.

The paving stone surface appears varied and visually appealing.
