description

The innovation relates to a climbing device according to the preamble of protection claim 1.

The construction principle of such a climbing device is described, for example, in the time "Bauwelt", 1960, issue 17, page 716. There it says: ^H The construction of this device is composed of a "wide-meshed" outer support frame (space framework) made of pipes that only Absorbs compressive forces, and from a "close-knit" inner space network made of ropes that only absorbs tensile forces. "

In such a climbing device, a number of the uppermost tubes of the largely rigid support frame usually form a tip to which the space net is attached. These uppermost, similar to a dome striving to the top In the following, pipes are called coupling pipes. They are carried by underlying pipes that are in the The following are called support tubes and two of them always support the lower end of a coupling tube. In addition, in known climbing devices of this type, the lower ends of two adjacent coupling tubes are each connected by a rigid connection. The entirety of these connections forms a framework as lower termination for the dome, so that the lower ends of the dome tubes cannot move outwards when the top of the space framework is burdened by children exercising on the space net.

It is the task of the present innovation to design a climbing device according to the preamble of protection τnspruches 1 so that the number of Roht - ¹ OS support frame is reduced.

This object is achieved by a climbing device with the features of claims 1 or 2.

As a result, not only the material requirement can be reduced, but also that largely rigid space framework also appears more graceful.

Advantageous further developments are given in the subclaims.

15th

Basically, a built-in according to claim 1 in the support frame, from two sides adjacent to each other Diamond-shaped element formed by triangles, at its corner points attack the predominantly inward tensile forces of the spatial network and in which the distant ones Corners of the neighboring triangles are connected by a pull rope, a stable construction unit, which is preferably a basic element for such climbing frames.

25th

The climbing device according to claim 2 has the additional advantage that all horizontally arranged rigid connections between the lower ends of adjacent coupling tubes omitted; as these horizontal connections have so far been quite close to the spatial network and therefore close to the play area were arranged by children to climb, they have an un-

danger of falling, which is now no longer applicable. The pull ropes that have been added to the new climbing device instead, which run diagonally downwards from the top of the support frame, on the other hand, increase the play value of the climbing device, because they can be used as continuous climbing ropes, creating a play area that was previously not available in climbing equipment with a spatial net made of ropes.

It is surprising that the rigid connections used so far, which served as the base frame for the dome, omitted at all and replaced by the pull cords could become. This is because that between the top, the base points of the dome and the foundations spanned space network, especially when under load, does not seek to reach the top of the support frame pulling it down, but on the contrary pushes it upwards while striving towards the base points of the dome Forces are exerted. The pull ropes effectively counteract these efforts and forces.

As a result of the anchoring forces exerted by the additional tension ropes, the number of foundation points can be reduced compared to previously known solutions.

The climbing device shown as an example initially consists of a self-contained, largely rigid support frame with a point s, from which four coupling tubes kj_, IC3, k $, kj extend downward. Dear dome tubes end at the bottom at rnsispunkte b] _ _f b3, b $, bj of the dome formed by the dome tubes. At their lower ends, i.e. at the base points, the coupling tubes k ^, k3, k5, k7 are each supported by two ropes si, S2 or S3, S5, Sg or S7, Sß. These support tubes, each spreading downwards from each other, rest in pairs on foundations fj_, £ 3, 1η.

In this support frame, the spatial network of ropes is attached in three different levels, namely once at the tip s, then in a middle level, namely at the base points b \, b3, b $, b ₇ and finally near the ground to the foundations f ^ , f3, £ $, f ₇ . As a result of the tension forces of the spatial network r, which preferably point inwards, and in particular when it is loaded, the tip s is pushed upwards and forces act on the base points in the direction of a vertical central axis running through the tip.

These forces on the tip and the base points are now counteracted by traction cables Z ₁ , Z3, Z5, Z7, which have taken the place of known rigid connections between adjacent base points. The traction ropes each grip on the one hand at the tip s and on the other hand at one of the foundations. In this way, a very simple construction was created, in which only three pipes have to be held together at each base point *

SE31.G1 page 9

An embodiment is preferred in which four coupling tubes, eight support tubes and only four foundations are provided, in which the spatial network r is not held on special Lu r foundations between the foundations shown in the drawing, but only in this ground level on the foundations f ^, fß, fs, ίη.

However, embodiments are also conceivable in which three or five coupling tubes and foundations and six or ten support tubes can be used. Embodiments are also possible in which the support tubes are not directly rest on foundations, but on additional support tubes.

In the illustrated, preferred construction, the necessary stability is easiest to achieve when the diamond-shaped frame from which the three-dimensional framework-shaped Support frames are assembled, for example the frame k ^, k3, S3, S2, each essentially in one single level is arranged in which the associated pull rope Z3 is tensioned. This pull rope is only connected to the support frame at both ends, but not to the spatial network in between Ropes, so that the tension of the tension rope is not influenced by the load on the spatial network and thus the Pull rope can be used as a continuous climbing rope like a mountain rope, the child with the Hands on the rope, while the feet find support in the space net.
