Articulated spatial knot for folding mechanisms of vanes, has circular piece or prismatic crossed transversely by perforation, which rotate in volume to axis of parallel planes so no perforation touches to immediate low or superior

摘要

The knot has a circular piece or prismatic crossed transversely by perforation, which rotate in volume to the axis of the parallel planes so no perforation touches to the immediate low or superior. The perforations serve to pass in to the transverse bolts, thymes or pins, which connect tangent bars to the piece with an object, which turn in volume to articulation.
