Detachable joining piece for construction of three dimensional structures e.g. counter displays, shelving and scaffolding

摘要

The demountable unit for joining pieces is made up of a sphere (1) containing 62 detachable male elements (4) positioned at right angles to the surface of the sphere and at an angle of 30 degrees one with the other. These male parts (4) come in contact laterally with female parts (6) to which they are anchored. The sphere consists of 12 recesses (2) when looking at it in cross section.
