ABSTRACT:
A spatial network, in particular a climbing device for children. The climbing device is composed of a three-dimensional inner net of tensile members and a three-dimensional outer net which serves to hold the inner net. The three-dimensional outer net consists of tensile members forming polyhedral and polygonal curved edges and doubly-curved faces. The polyhedra have a maximum of eight verticies and have their faces, in operation, at an angle to the vertical. The three-dimensional inner net consists wholly or partly of at least one continuous ring, in particular a rope ring. The ring forms several interlinked polygonal meshes such as polygonal faces defined by its edges which consist of the tensile members.
