In the illustrated embodiment, the ground anchor 1 is provided for this purpose with a central, over the entire length of the ground anchor 1 extending portion 3, on which the ground anchor 1 is convex on one side and concave on the opposite side. The section 3 is V-shaped or substantially V-shaped and merges into a flat section 4 on the two longitudinal sides of the ground anchor 1, these sections 4 lying with their surface sides in common planes parallel to the longitudinal extent L of the ground anchor.

In the area of section 3 of the ground anchor 1 is formed with a plurality of barbs 5 and 6, which follow one another in the direction of the longitudinal extent L and which are each produced by partial punching and bending out of the strip material of the ground anchor 1. The barbs 5 and 6 are related to the longitudinal extent L obliquely away from the ground anchor 1, in such a way that they include with this longitudinal extent each an angle smaller than 90 °, which is at the barbs 5 to the top, the end 2.1 opposite end 2.2 and barbs 6 opens to the lower end 2.1 of the ground anchor 1 out. Further barbs correspond to the barbs 5 and 6 may also be provided on the outer portions 4, as shown in the FIG. 3 indicated by broken lines.

The barbs 5 counteract after hitting the ground anchor 1 in the ground at tensile loads an unwanted pulling out of the ground anchor 1, while the barbs 6 prevent under pressure loads unwanted additional impressions of the ground anchor 1 in the ground.

The ground anchor 1 has, for example, a total length in the range between 400 and 500 units and a material thickness in the range between three and four units. The distance between similar, in the direction of the longitudinal extension L consecutive barbs 5 and 6, for example, one hundred units, wherein in the middle between two successive barbs 5 in the longitudinal direction on one side of the ground anchor 1, a barb 5 on the other side of the ground anchor 1 provided. In the illustrated embodiment, the barbs 5 and 6 are still away with a length of about 20 units on the respective side of the ground anchor and have perpendicular to the longitudinal extent L a width of 10 units. The width of the ground anchor 1 is in the range between 35 and 60 units. A unit is for example a millimeter.

In the illustration in the figures, the barbs 6 are provided only on one side of the ground anchor 1, on the convex side of the section 3. But there are also barbs 6 on the other side of the ground anchor possible.

The number of barbs 5 on the two sides of the ground anchor 1 is identical, i. In the illustrated embodiment, three barbs 5 are provided on each side of the ground anchor 1 respectively.

The FIGS. 4 to 7 show a sleeve-shaped adapter 7, which is elastically deformable made of a suitable material, such as metal or plastic sleeve-like, in such a way that it can be attached to the upper end 2.2 of the ground anchor 1 by sliding on this end. Adapted to the cross-sectional shape of the ground anchor 1, the adapter 7 has a wall 8 limiting the adapter opening 8, which is convexly formed on the outside of the adapter and in which an opening 10 is formed. In this engages after pushing the adapter 7 on the ground anchor 1, a barb 6, which is provided on the recorded in the adapter opening 8 upper part length of the ground anchor 1. Furthermore, the wall portion 9 is formed above the opening 10 so that it forms an inwardly extending portion 11 which rests after placing the adapter 7 on the ground anchor 1 against the upper, the tip 2 opposite end of the ground anchor 1, so that the Adapters 7 tensile and pressure resistant on the ground anchor 1 is held.

The adapter 7 is the basis or component of various functional elements or attachments, for example, basis for or component of Begrenzungsposten etc. The ground anchor 1 is then driven, for example so far into the ground or ground that the lower end of the 2.1 facing the end of the sleeve-like adapter 7 on the Level of the underground is located.

The Fig. 8 - 10 show a ground anchor 1a, the Erdankerkörper 2 band or strip-like made of a flat material, for example of a metallic sheet, preferably made of a corrosion-resistant metallic flat material, for example made of stainless steel. The Erdankerkörper 2 is profiled to increase the mechanical strength of Erdankers 1a, in particular with respect to a bending, ie slightly wavy, in such a way that the elevations 12 and depressions of this profiling or undulation in the direction of the longitudinal extension of the ground anchor 1a and parallel extend to the long sides 2.3 of Erdankerkörpers 2. In detail, the profiling or undulation of Erdankerkörpers 2 is formed so that at the in the Fig. 8 Visible on the front three in total towards the Longitudinal extent L extending elevations 12 and two intermediate wave troughs are provided, wherein a survey 12 extends in the middle. At the back, the Erdankerkörper 2 accordingly two surveys, and a total of three wave troughs, namely a wave trough between the two elevations there and 12 each a trough between a survey and the adjacent extending in the direction of the longitudinal extension L longitudinal edge 2.3 of Erdankerkörpers, the Longitudinal edges 2.3 are arranged in a common plane with the elevations on the back.

The ground anchor 1 a in turn has a lower end formed as a tip 2.1 and an upper end 2.2 and various barbs 5, which are formed by partial punching of the sheet in the middle elevation 12 and by bending out, and of which, for example, two barbs. 5 about in the Fig. 8 visible front and a barb 5 over in the Fig. 8 not visible back of Erdankerkörpers 2 stand out. The longitudinal extent of each barb 5 forms with the longitudinal extent L an angle smaller than 90 °, which opens to the upper end 2.2 out.

Below the upper end 2.2 of Erdankerkörper 2 is provided with a plurality of bores 13, which serve for attachment of other functional elements, including adapters on the ground anchor 1 a, for example, for attachment of limiting elements made of material, such as lawn edge boundary elements 14, as shown in the Fig. 8 indicated by broken lines.

The Fig. 11 - 13 show a ground anchor 1 b, which differs from the ground anchor 1a essentially only in that the ground anchor 1 b has at its lower end two tips 2.1, which are provided on both sides of the longitudinal extent L and mirror symmetry to this, in such a way that each longitudinal side of the Erdankerkörpers 2 merges into a tip 2.1, in the illustrated embodiment in a straight line.

The Fig. 14-16 show as another embodiment, a ground anchor 1 c, which is formed by two with their back against each other and connected Erdankerkörpern 2, which correspond to the Erdankerkörper 2 of Erdankers 1a, but with the difference that at each ground anchor body 2 of the ground anchor 1 c barbs protrude only over the opposite outer sides of the two interconnected Erdankerkörper 2. The two ground anchor bodies 2 of the ground anchor 1c are identical in shape and size and connected to one another in such a way that they form a ground anchor double body 2a with a common tip 2.1 and with a common upper side 2.2 of the ground anchor 1. The two Erdankerkörper 2 are for example by Spot welding or brazing in the region of touching corrugations or elevations 12 connected to each other. Other types of connection, for example by mechanical fasteners such as rivets, etc. are possible.

The Fig. 17 - 19 show a ground anchor 1d, which differs from the ground anchor 1c substantially only by having two peaks at the lower end of Erdankerdoppelkörpers 2a. In detail, the ground anchor 1d or its Erdankerdoppelkörper 2a are formed by two Erdankerkörpern, each corresponding to the Erdankerkörper 2 of the Erdankers 1 b and are the same in shape and size. The two Erdankerkörper 2 are in turn connected to each other with their back against each other, by spot welding, brazing or otherwise. The barbs 5 produced on each Erdankerkörper 2 are each about the other Erdankerkörper 2 side facing away.

The Fig. 20 - 22nd show as further embodiments a ground anchor 1 e, which differs from the ground anchor 1a substantially only in that the barbs 5 are not provided on the Erdankerkörper 2, but instead of these barbs from the sheet of Erdankerkörpers 2 by partially punching and bending a clamping plate 15th is shaped over in the Fig. 20 visible front side of the Erdankerkörpers 2 protrudes and the upper end 2.2 is substantially closer than the lower, designed as a tip 2.1 end. The clamping plate 15 forms a clamping gap 16, in which from above a functional element, for example, formed by a flat material grass edge boundary 14, for example, with the edge of a mounting hole 14.1 inserted and can be fastened by clamping.

The Fig. 23 - 25 show as a further embodiment, a ground anchor 1f, which differs from the ground anchor 1e characterized in that at the bottom again two tips 2.1 are formed, each longitudinal side 2.3 of Erdankerkörpers 2 ends in each case a tip 2.1 or in a straight line in a peak 2.1 passes.

The FIGS. 26 and 27 show as another embodiment, a ground anchor 1 g, which differs from the ground anchor 1 f in that the clamping plate 17 is formed on a Erdankerabschnitt 2 a, made of the profiled or wavy sheet material by punching and bending and adjustable in the longitudinal direction L on Erdankerkörper 2 this is mounted resting (double arrow A), in the illustrated embodiment with holes 17 of rows of holes by mechanical fasteners, such as screws, rivets, etc. The Erdankerabschnitt 2 a is guided with its corrugation at the corrugation of Erdankerkörpers 2, namely with relief of mechanical fastener.

The in the FIGS. 8-25 For example, ground anchors 1a-1g also serve, for example, each as support and / or support and / or holding element and are also suitable, for example, for use in gardens and / or parks, but also for other uses.

The invention has been described above by means of an embodiment. It is understood that numerous changes and modifications are possible. So it is for example possible to profile the ground anchor in the longitudinal direction differently than described above, for example in the form that it forms in cross-section perpendicular to its longitudinal extent L an angle profile with at least two, an angle greater than 90 ° with each other enclosing legs or but has a multiple angled cross-section, for example in the form that at an intermediate portion on both longitudinal sides in each case an angled portion is provided, which forms an angle greater than 90 ° with the central portion.

Furthermore, it is also possible to provide a barb 6 only at the top, received by the adapter 7 part length of the ground anchor, which then serves in the manner described above for sealing the adapter to the ground anchor.
