The invention relates to a rope game device with an outer frame and ropes arranged within the outer frame and forming a spatial net and which are attached in a tensionable manner to defined node points of the outer frame.
Rope game devices are known. They are erected on children's play areas as well as on sport- and leisure facilities for climbing, working one's way along with one's hands and swinging. Climbing frames for children with a support frame defining the outer contour of the frame and a spatial rope net rigged therein, are known for example from DE-A 2046791. Between the node points of the support frame, formed as a cuboid or a octahedron, ropes are rigged as connecting element. In this case, also compression rods of the support frame can be partially omitted and can be substituted by an inner compression rod in the spatial rope net. The spatial net is, then, as a whole elastic and it can swing. The there described frame shape on the basis of a square is, as a single game device, however, not very attractive, as on the one hand no distinct spatial net volume is achieved and on the other hand the device can not be combined by a modular construction to larger units, so that besides a multiplication of the individual device no effect concerning the design of attractive spatial shapes can be achieved. In larger game devices, therefore, support frames are used according to the type of a polyhedron, in which internal space an individual, larger rope net is rigged in a stretched manner.
In WO 02074392 A2 a rope game device is described, which has a support frame, which consists of pentagon frame elements, wherein within each frame element a separate rope net is rigged. For connecting the frame elements as well for the anchoring of individual ropes, the already known hollow ball connectors are used. This pentagon-like game devices, which refer back to the dodecahedron-series, have the disadvantage, that a larger number of rope elements and frame elements of different lengths are used, which make the manufacture of these devices technologically complex and costly.
Furthermore, this rope game device is missing a specific “fullness” of the inner structure of the spatial net.
The invention is based on the object, to provide a new rope game device, which is characterised by a particular “fullness” of the spatial net and which manufacture has distinctive technological as well as cost advantages compared to the known devices.
The object is solved by the features of claim 1. Thus, the rope game device with outer frame is characterised in that the outer frame has an icosahedron shape, consisting of frame elements forming equilateral triangles and which triangle tips are connected at the node points to each other and that the inner structure of the spatial net has one or more football-like hollow ball modules arranged within one another and which are retained by guy ropes at the node points of the outer frame.
Advantageous improvements are stated in the dependent claims.
The advantages of the rope game device according to the invention are as follows:
In an embodiment of the invention one outer hollow ball module is retained in a tensionable manner by means of guy ropes at twelve node points of the icosahedron shape.
A further embodiment provides, that an inner hollow ball module is retained by connecting ropes at the outer hollow ball module.
A further embodiment provides, that the outer frame has thirty rods of equal length, which ends are connected to the node points.
In a further embodiment the outer frame has further stabilising elements.
In an improvement the ball modules have twelve regular pentagons and twenty regular hexagons.
A further embodiment provides, that, starting from the corners of each pentagon of the outer hollow ball module, respectively, five guy ropes are brought together in a pyramid manner at the node point and are retained there in a tensionable manner.
In a further embodiment the corners of each pentagon of the outer hollow ball module are, respectively, connected to five connecting ropes to the corners of each pentagon of one or more inner hollow ball modules.
In a further embodiment one hollow ball module is composed of two rope elements of different lengths and which are shorter concerning the inner hollow ball modules.
A further embodiment provides, that the connecting ropes are extended guy ropes.
A further embodiment is characterised in that the twelve node points, connected to each other by rods, are formed as hollow bodies, comprising the rope tensioning elements.
A further embodiment is characterised in that the rods are retained by threaded bolts on a wall of the hollow body.
A further embodiment provides, that the rope tensioning elements are retained in or at the wall of the hollow body, respectively.
The hollow ball modules, achieved by shortening of an icosahedron structure, consisting of twelve pentagons and twenty hexagons, have the form and structure of a football. In contrast to the known spatial rope net modules based on an octahedron, which can be piled on top of each other, and thus, a spatial fullness is achieved, in this case the football-like hollow ball modules are arranged within one another. As in the icosahedron structures all corners are identical and, thus, also the guy points can be formed identically, the spatial nets contain repeatedly occurring identical rope elements, like guy ropes and connecting ropes.
A small hollow ball module is formed only from two differently long guy ropes or connecting ropes, respectively:
The guy rope, extending from tensioning point to tensioning point and simultaneously forms the edges of the hexagon (thirty pieces), and the connecting rope, forming the pentagon (twelve pieces).
If in a larger device a further small hollow ball module should be arranged in the first larger hollow ball module, one only needs 12 times a further smaller pentagon rope position, while the guy ropes are additionally extended, to anchor the inner hollow ball module and to form the edges of the hexagon of the inner spatial ball net.
The invention is explained in detail by means of the drawings and an exemplary description.
