Three-dimensional network
First Claim
1. A spatial network, in particular a climbing device for children, comprising a three-dimensional inner net of tensile members, and a three-dimensional outer net which serves to hold the inner net , said three-dimensional outer net comprises tensile members forming polyhedra and polygonally curved edges and doubly-curved faces, said polyhedra having no more than eight vertices and having their faces, in operation, at an angle to the vertical and said three-dimensional inner net comprises at least one tensile member forming a continuous ring, said ring forming several interlinked polygons having faces defined by its edges which consist of said tensile members.

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.
