Description

boundary stone

The invention relates to a boundary stone, for example for the formation of a path, lawn or Beetkante, according to the preamble of claim 1.

Such boundary stones are known for example from DE 10 2005 048 265 A1. In this boundary stone, the one end face is formed as a semicircular head and the other end face as a semicircular bulge whose radius corresponds to that of the head. Further, two or more circular segment-shaped portions are formed on one of the two longitudinal sides of the boundary stone whose radius corresponds to that of the head. These boundary stones can be lined up in a simple manner, with two boundary stones each interlocking by the alternately convex and concave formation of the end faces. Due to the lateral circular segment-shaped sections, a uniform-looking edge profile is achieved in the case of a lawn or bed edge formed from a plurality of boundary stones, since it is not possible to detect whether two adjacent circular segment-shaped sections belong to one and the same boundary stone or to two consecutive boundary stones.

With the help of these known boundary stones can thus be arbitrarily long contiguous boundary edges, the edge profile can vary between rectilinear and angular. Although it is also possible to form curve-shaped and circular boundary edges, they always have a polygonal-like appearance and thus have the more angular the smaller the radius of the curve or the circle.

BESTATIGUNGSKOPIE The invention has for its object to make a boundary stone so that it can be formed with him arbitrarily extending and this particular curve and circular boundary edges.

The object is achieved in that in a boundary stone with a top, a bottom, two longitudinal sides and two end faces, in which one end convex and the other end face of the same radius is concave, the two end faces in accordance with the invention at an acute angle run obliquely to each other and the shorter longitudinal side is concave and the longer longitudinal side is convexly arcuate.

With this on all sides arcuate and thereby partly concave and partly convex shaped boundary stones, in which the front sides additionally extend at an acute angle to each other, now different sized, designed as a partial or full circle rows of stones can be used, for example, serve as a boundary edge. Ideally, such a partial or full circle has such a size that the facing end faces of adjacent boundary stones either abut each other over the entire surface or that the boundary stones are laid with equally wide joints between the end faces. Conversely, if the boundary stones are laid in much narrower or wider circles or arcuate shapes, the concave / convex shape of the long sides will cause such patterns to be non-angular or polygon-like. Since in narrow or wide circles or arcs, the faces of adjacent boundary stones are not over the entire area, but at best linear contact or existing between them joints are not the same width, but have a curved, more or less acute-angled wedge shape, which in narrow Circles or arches to the outside, and open in wide circles or arches inward toward the center, arises on This way, a relaxed, harmonious installation image. Thus, due to the irregular shape of the boundary stones with a single stone form can achieve a large variety of installation, which also creates the visual impression as if different stone shapes or stones of different sizes have been used.

According to a further proposal, the radius of the end faces is greater than the measure of the distance between the longitudinal sides. In this way, two mutually corresponding end faces of two adjacently placed limiting stones form a flat, open joint. Such an open joint allows for the laying of the boundary stones a much larger variety of variants than a semi-closed joint, as is known by the prior art described above.

By the measure to make the boundary stones so that their top and bottom have the same surface texture, they can be moved either in one or the other orientation and thereby also in any change within a laying image. This makes it possible with the arcuate on all sides and thereby partly concave and partly convex shaped boundary stones not only to create differently shaped arch shapes with any concave o- convex course, but also to form approximately rectilinear-looking rows of stones by the boundary stones alternately with the top and The bottom side are strung together so that the tangents of the successive consecutive left and right concave and convex longitudinal sides are each on a common line. According to a further proposal, the shape of the concave and convex longitudinal sides is formed as a pitch circle, wherein the two pitch circles have a common center. This makes it possible to form a precisely circular row of stones with the boundary stones thus formed, in which the inner and outer radius of this row of stones corresponds to the respective radius of the concave and the convex longitudinal side of the boundary stones.

By the further measure that the radius of the concave longitudinal sides substantially corresponds to the radius of the end faces, two boundary stones or two rows of stones can be aligned substantially perpendicular to each other in a visually appealing manner by a boundary stone with its convex end face to the concave longitudinal side of the adjacent Limiting stone is created. Since the radius of the front side corresponds to the radius of the associated longitudinal side, the joining of the boundary stones can take place either over the entire surface and thus substantially gap-free or with an equally wide joint, so that even in an abrupt right-angle direction change in the corner results in a harmonious picture.

If one end side extends substantially at right angles to the longitudinal sides and the other end side obliquely to the longitudinal sides, one achieves a particularly large possibility of variation in laying with such a stone shape, whereby an intentional use of arbitrarily-looking joint forms enables an unlimited variety of differently designed laying patterns.

If according to another proposal, the two end faces extend substantially at the same angular amount obliquely to the longitudinal sides and thus the boundary stone in plan view similar to a uniform trapezoid, can be created preferably uniform looking installation images. So z. B. when laying a straight-looking row of stones, the boundary stones are arranged so that the joints between the end faces look substantially the same width. A series of stones designed in this way gives a more self-contained impression than if the joints were wedge-shaped.

Further details and advantages of the invention will become apparent from the following description of two illustrated in the accompanying drawings, different embodiments of boundary stones and a plurality of installation images formed with them.

It shows:

Fig. 1 shows a first embodiment of a boundary stone with two extending at different angles to the longitudinal sides

End faces;

Figure 2 is a partial circle with a smaller radius. 3 shows a pitch circle with a medium radius; 4 shows a pitch circle with a larger radius; Fig. 5 is a substantially rectilinear row of stones, in which the boundary stones are strung together seamlessly; Fig. 6 is a circle of circles with a very large radius, in which the boundary stones are lined up seamlessly; 7 shows a laying image with a right-angle direction change; 8 shows a substantially rectilinear stone row, in which the boundary stones are tangentially aligned with each other; 9 shows a second embodiment of a delimiting block with two end faces running essentially at the same angle to the longitudinal sides; 10 is a formed with a boundary stone of FIG. 9, We- significant linear stone row, in which the boundary stones are aligned tangentially to each other.

The limiting stone 1 illustrated in FIG. 1 as a first embodiment has a convex longitudinal side 2, a concave longitudinal side 3, a convex end face 4 and a concave end face 5. The adjacent to the longitudinal sides 2, 3 tangents are denoted by T2 and T3 and the voltage applied to the end faces 4, 5 tangents in a corresponding manner with T4 and T5. Here, the tangent T4 of the convex end face 4 and the tangent T5 of the concave end face 5 at an acute angle a obliquely to each other, whereby the convex longitudinal side 2 is longer than the concave longitudinal side 3. In the first embodiment, the concave end face 5 extends substantially at right angles to the two longitudinal sides 2, 3 and the convex end face 4 obliquely to the longitudinal sides 2, 3rd

The shape of the convex and concave longitudinal side 2 and 3 corresponds in each case to a pitch circle, the radii R1 and R2 of the two pitch circles or the two longitudinal sides 2 and 3 having a common center. In this way, the two longitudinal sides 2 and 3 are concentric with each other. The mean radius between the aforementioned radii R1 and R2 is denoted by R3.

The shape of the convex and concave end faces 4 and 5 also corresponds in each case to one pitch circle, but in this case the respective radius R4 of the two pitch circles or the two end faces 4 and 5 is the same size. In this case, the radius R4 of the two end faces 4 and 5 is greater than the measure of the distance between the two longitudinal sides 2 and 3. This leads to the fact that two boundary stones 1 with a convex end face 4 and a concave end face 5 are jointless pushed against each other, these faces as the components of a flat of- Fenen joint can be considered. Furthermore, the size of the radius R4 of the end faces 4 and 5 substantially corresponds to the size of the radius R2 of the concave longitudinal side 3.

The visible in Figure 1 top is denoted by the reference numeral 6 and the underside not visible here with the reference numeral 7. When making the boundary stones 1, care is taken to ensure that their upper side 6 and their underside 7 have the same surface texture with regard to surface structure and color. In this way, the boundary stones 1 can be either in one or the other orientation position, d. H. any laying either with the side or the surface 6 or the side or the surface 7 lying above without this would be recognizable from the appearance of the overhead surfaces ago.

In FIGS. 2 to 8 it is explained how a multiplicity of arbitrarily shaped stone rows or laying patterns can be formed with the boundary stones 1 designed according to the invention.

FIG. 3 shows a stone row 10 formed as a pitch circle, in which the boundary stones 1 are arranged such that the mean radius R5 of this row of stones corresponds to the mean radius R3 of the boundary stones 1. In this case, the convex longitudinal sides 2 of the boundary stones 1 extend concentrically and congruently on the outer circumferential circle and the concave longitudinal sides 3 concentrically and congruently on the inner circumferential circle of the stone row 10. Furthermore, in this row of stones 10, the mutually facing or mutually corresponding end faces 4, 5 adjacent boundary stones 1 parallel to each other, so that the boundary stones 1 either over their entire surface lying against each other and thus gap-free or, as shown in Fig. 3, with equal width joints 1 1 between the end faces 4, 5 can be laid. In Fig. 2, another, also designed as a circle circle stone row 12 is shown, in which the boundary stones 1 are arranged so that the average radius R6 of this row of stones is smaller than the average radius R3 of the boundary stones 1. In this case, the facing each other or mutually corresponding end faces 4, 5 adjacent boundary stones 1 not parallel to each other as in the row of stones 10, but touch, if they are pushed as shown in Fig. 2 abutting, only linear, so that between them curved, an acute-angled wedge-shaped joints 13 are formed, which open to the outside.

In Fig. 4, a further, also formed as a circle circle stone row 14 is shown, in which the boundary stones 1 are arranged so that the average radius R7 of this stone row is greater than the average radius R3 of the boundary stones 1. Also in this case are between the 1 facing each other facing or mutually corresponding end faces 4, 5 adjacent boundary stones 1 curved, acute-angled wedge-shaped looking joints 15 are formed, however, unlike the stone row 12 in this case open inwards.

The changing depending on the size of the radius of the stone row direction of the openings of the joints with one and the same stone form makes it possible to form a full circular area, in the inner area, the opening of the joints to the outside (Fig. 2) and in the outer area the opening of the joints is directed inwards (FIG. 4). In this case, the change in the direction of the openings of the joints takes place steadily, with a central region is formed in which the joints along the end faces of the abutting stones are the same width (Fig. 3). This effect is particularly evident when a circular area is not completely covered with stones, but only individual concentric annular surfaces are covered with stones, so that the direction of the openings of the joints of the inner annular surface to the outside and the openings of the joints of the outer annular surface extends inwardly, in which case also a central annular surface is formed, in which the width of respective joints between two adjoining end faces of the stones is the same width along their entire length.

Fig. 5 shows a row of stones 16, in which the boundary stones 1 were alternately laid with the visible in Fig. 1 top 6 and not visible in Fig. 1 underside 7 lying above so that the mutually facing convex and concave end faces 4, 5th adjacent boundary stones 1 gap abut each other. In this way, the stone row 16 conveys the impression of a substantially rectilinearly extending laying image. Due to the continuous succession of convex and concave longitudinal sides 2 and 3, however, results in the row of stones 16 a wavy edges, this image is further enhanced by the fact that the tangents T2 and T3 of the long sides 2 and 3 each at a shallow angle obliquely to each other run.

The row of stones 17 shown in FIG. 6 essentially corresponds to the row of stones 16 in FIG. 5, but with the difference that in it the boundary stones 1 are slightly hinged against each other, so that they form a pitch circle with a very large mean radius R8.

In Fig. 7 it is shown that two boundary stones 1 can be laid substantially perpendicular to each other by a boundary stone 1 with its convex end face 4 to the concave longitudinal side 3 of an adjacent boundary stone 1 is applied. Since the radius R4 of the end face 4 essentially corresponds to the radius R2 of the associated longitudinal side 3, the joining of the boundary stones 1 can take place either essentially without a gap or, as shown in FIG. 7, with a substantially uniform gap 18. In this way, a harmonious picture is achieved even in an abrupt right-angled change of direction of two straight stone rows in the corner.

In the row of stones 19 shown in FIG. 8, as in the row of stones 16 in FIG. 5, the boundary stones 1 are laid alternately with the top 6 visible in FIG. 1 and the underside 7 not visible in FIG There is a constant change of the convex and concave longitudinal sides 2 and 3 on both sides of the row of stones 19. Here, however, the boundary stones 1 have been laid so that the tangents T2 and T3 of the left and right concave and convex long sides 2 and 3 are each on a common line. Even if in this way of laying between the facing end faces 4, 5 adjacent boundary stones 1 each an acute-angled wedge-shaped joint 20 is formed, so mediates the stone row 19 but still much more than the row of stones 16 a straight-looking installation pattern, because by the tangentenmäß orientation of Limiting stones 1, the wave-shaped edge course of the stone row 19 compared to that of the stone row 16 is mitigated.

The limiting stone 21 shown in FIG. 9 as a second embodiment is designed substantially similar to the limiting stone 1 and therefore also has a convex longitudinal side 22, a concave longitudinal side 23, a convex end 24 and a concave end 25. The tangents on the longitudinal sides 22, 23 are tangent with T2 'and T3' and the tangents on the end faces 24, 25 in FIG. speaking manner designated T4 'and T5'. Here, the tangent T4 'of the convex end face 24 and the tangent T5' of the concave end face 25 at an acute angle b obliquely to each other, whereby the convex longitudinal side 22 is longer than the concave longitudinal side 23. In the second embodiment, the two end faces 24 and 25 and their tangents T4 \ T5 'substantially at the same angle amount obliquely to the longitudinal sides 22, 23. Due to this, the boundary stone 21 in the plan view looks similar to a uniform trapezoid.

The shape of the convex and concave longitudinal side 22 and 23 corresponds in each case to a pitch circle, the radii RV and R2 'of the two pitch circles or of the two longitudinal sides 22 and 23 having a common center. In this way, the two longitudinal sides 22 and 23 are concentric with each other. The shape of the convex and concave end faces 24 and 25 also corresponds in each case to one pitch circle, the respective radius R4 'of the two pitch circles or of the two end faces 24 and 25 being the same size.

The visible in Figure 9 top of the boundary stone 21 is denoted by the reference numeral 26 and the underside not visible here by the reference numeral 27. The top 26 and the bottom 27 have like the top 6 and the bottom 7 of the boundary stone 1, the same surface finish.

In the illustrated in Fig. 10, formed with the boundary stones 21 stone row 28, these are alternately laid with the visible in Fig. 9 top 26 and 9 invisible in Fig. Bottom 27 in the manner above, that it is on both sides of the Stone row 28 is a constant change of the convex and concave longitudinal sides 22 and 23 are. Here, the boundary stones 21 were similar to the stone row 19 in Fig. 8 laid in such a way that the tangents T2 'and T3' of the left and right concave and convex long sides 22 and 23 are each on a common line. Since the boundary stones 21, the two end faces 24 and 25 extend substantially at the same angular amount obliquely to the longitudinal sides 22, 23 and the boundary stones 21 consequently look similar to a uniform trapezoid, they can with their facing end faces 24, 25 placed almost gap-free or, in the case where the boundary stones 21 are laid on the gap, the joints then formed between them would look substantially the same width. Because of these conditions, the rectilinear stone row 28 formed with the boundary stones 21 has a more self-contained appearance than the stone row 19 formed with the boundary stones 1.
