Spatial union system for three dimensional structures e.g. table structures, has one of six pieces having quadrangular profile, while remaining pieces are of tubular profiles some formed with reduced intermediate extensions

摘要

The system includes six different pieces all formed with inlets and complementary protrusions. One of the pieces is formed as a quadrangular profile, while the remaining pieces, some formed with reduced intermediate extensions, are of tubular profile. All pieces also have bolt holes. Through the matching inlets and protrusions, the pieces can be connected together in rectilinear or square direction to define various spatial configurations for three dimensional structures.
