ELEMENTS FOR CONSTRUCTING A THREE-DIMENSIONAL STRUCTURE This invention discloses elements for constructing a three-dimensional structure, comprising beams that make edges, polygonal plates that make faces and joints with arms that connect said beams and/or polygonal plates with each other so that a desired structure is formed, wherein the end of said joint arms is formed into a spherical shape and bearings which have a grasping means for said spherical end of said joint arms are provided to said beams and polygonal plates so that any of said bearings can be engaged or disengaged with it freely; said joints are formed into at least two shapes from an elastic material so that they can be used singly or in conjunction with the other in connecting said beams and/or polygonal plates; and hooks are provided to each side of said polygonal plates so that said hooks can hold said beams by their sides. |
