In the FIG. 1 a slackline device according to the invention is shown schematically and marked with the position 1.

The slackline device 1 has a transportable and preferably cylindrically shaped holding element 2 with a surface 3 in which, according to the drawing, a vertically arranged recess 4 is formed in the edge region with a dimensioning not shown, on which a clamping edge 4.1 spaced apart from the edge region is provided.

The holding element 2 is preferably formed from cylindrical wood in a non-descript, comparatively large thickness D, whereby despite the thickness D easy handling and easy installation and transportability and favorable storage option achieved and a particularly safe for children and environmentally friendly product provided.

In accordance with the FIG. 1 in conjunction with the FIG. 2 As shown, the retaining element 2 has a base 5 in the position lying axially opposite the surface 3.

Like from the Figures 1 and 2 in further connection with the FIG. 3 can be seen, the slackline device 1 on a band 6 with dimensions not shown in detail, which is formed at its respective end portion 7 as a loop.

The end portion 7 is provided for receiving a, for example U-shaped clamping element 8, which is inserted with its transverse cross section here in the loop-shaped end portion 7 and used together with this in the recess 4 in the correct position, so that the clamping element 8 corresponding to the end portion. 7 of the band 6 is located.

By using appropriate means at the end portions of the clamping element 8 (not shown) is then the respective end portion 7 of the belt 6 in the recess 4 and according to the drawing from below, first fixed in the holding element 2 and the tape 6 placed over the clamping edge 4.1.

How further from the FIG. 1 It can be seen that the slackline device 1 has a tubular strut 9 with a defined length L and end sections 9.1, which is not described in more detail, for example formed from metal.

The strut 9 is connected in a distance defined in accordance with the length L with a second retaining element 2 designed in the same way as the first retaining element 2 described above, wherein the respective end sections 9.1 of the strut 9 are each vertically aligned at a distance A below the perpendicular Clamping edge 4.1 in the holding element 2 radially introduced recess 10 can be fixed.

In the predetermined by the recess 10 distance A parallel to the strut 9 extending, the band 6 is one of the Slacklinevorrichtung 1 corresponding length arranged with its second end portion 7 shown here with a further clamping element 8 in the manner analogous to the first holding element 2 Recess 4 inserted and fixed in the second holding element 2, so that the band 6 also corresponds to the clamping edge 4.1 at this position.

By a precisely coordinated formation of the lengths L of the band 6 and the strut 9, the band 6 can be arranged by means of the clamping elements 8 in a fixed clamping strength and it is thus as a simple slackline device 1 for use operational.

Because of a possible fatigue of the material of the belt 6 and release of the clamping force, an adjusting device 11 is provided on the brace 9 in the region of one of the end sections 9.1, which is formed from an axially arranged threaded portion 12 with an adjusting means 13.

By a corresponding adjustment of the adjusting means 13 along the threaded portion 12 and, for example, directed against the corresponding holding element, an increase in the length L or an extension of the strut 9 is achieved, whereby the clamping force of the band 6 can be restored for use, increased or otherwise reduced on demand in a simple manner.

In the FIGS. 4a to 4c Possibilities for an inclination of the belt 6 in a slackline device 1 relative to the strut 9 and the footprint 15 are shown schematically.

While the band 6 according to the FIG. 4a opposite the strut 9 and the footprint 15 is taut in approximately parallel position is in the FIG. 4b a possibility for use shown, with the band 6 can be placed in a portion of its length L obliquely.

For this purpose, an intermediate element 14 can be provided with a specific shape and size, for example, between the strut 9 and the band 6 at a defined position on the strut 9 fixed or slidably on the mounting surface 15, and arranged over which the band is guided.

With this arrangement, an as required inclined position of the belt 6 by a corresponding, local and / or temporary change in the distance A of the belt 6 relative to the strut 9 and the footprint 15 with the same support elements 2 and in the position or height of their clamping edges 4.1 allows.

The Figure 4c shows another example of the inclination of the belt 6 in a slackline device. 1

Here, for example, equipped with the brace 9 slackline device 1 is equipped without the intermediate element 14, but one of the two holding elements 2 is increased by a second holding element 2 rigidly connected thereto in a vertical arrangement.

As a result, the band 6 on the one hand on the clamping edge 4.1 ( FIG. 1 ) of the drawing lower holding element 2, whereas on the other hand, the position of the belt 6 at the clamping edge 4.1 (see FIG. 1 ) is fixed in a by the thickness D of a raised with the holding element 2 shown below, rigidly connected further support member 2.
