Elements for constructing a three-dimensional structure

A three-dimensional structure, comprising:

• joint means including a plurality of connecting arms emanating from the exterior surface thereof;
• said connecting arms including a spherical locking member at the end opposite said joint means;
• said joint means including interlocking means for mechanically securing a plurality of joint means together;
• a plate including at least two straight edges forming a corner and means for retaining one of said spherical locking members located at said corner;
• and
• a beam terminated at each end by a means for retaining one of said spherical locking members and including a longitudinal slot for receiving one of said edges of said plate.

A three-dimensional structure, comprising:

• a plurality of joint means, each including connecting arms emanating from an exterior surface thereof;
• the free end of said connecting arms terminated by spherical locking members;
• said joint means including interlocking means for mechanically securing at least two of said joint means together;
• a plurality of plates, each including at least two straight edges forming a corner and means for retaining said spherical locking members located at said corner;
• and
• a plurality of beams, each terminated at each end by a mean for retaining said spherical locking members and including a longitudinal slot for receiving one of said edges of one of said plates.
