Pyramid puzzle system

#The present invention relates to the field of puzzles for educational and entertainment purposes, and more particularly it relates to a system of manual assembly puzzles wherein a set of puzzle-pieces, formed from rows of tangentially-attached spheres, can be assembled in a special non-apparent manner to form a pyramid.

#The pyramid as a geometric form has remained a source of fascination to mathematicians, historians and the general public alike for many centuries. The square-based pyramids built by the ancient Egyptians for royal tombs continue to grip the public imagination among the wonders of the world: historical man-made structures that remain mysterious despite scientific studies that have revealed extraordinary accomplishment in their concept, design and construction, based on mystic “golden rules” of the pyramid.

#Assembling a pyramid from puzzle-pieces presents an intellectual challenge that appeals to mentally active persons of all ages whether pursued for education or simply for relaxation.

#The above and further objects, features and advantages of the present invention will be more fully understood from the following description taken with the accompanying drawings in which:

#FIG. 1A shows a set of four puzzle-pieces that can be combined to form a pyramid of the triangle-based type.

#FIGS. 1B and 1C depict two steps in aligning and combining the puzzle-pieces of FIG. 1A to form the pyramid.

#FIG. 1A shows a puzzle set of four simple puzzle-pieces, in two matched pairs with a total of twenty spheres, that can be combined to form a triangle-based pyramid having four spheres along each of its six edges. The four spheres in the first single row, which can be regarded as a 1×4 matrix array, are identified as “a” and the four spheres in the other piece of the pair are identified as “b”. The six spheres in the first 2×3 array are identified as “c” and the six spheres in the second 2×3 array are identified as “d”.

#FIG. 1B depicts the four puzzle-pieces of FIG. 1A rearranged and aligned for assembling the pyramid.

#In FIG. 1C the “a” puzzle-piece is shown merged with the “c” puzzle-piece and the “b” puzzle-piece is shown merged with the “d” puzzle-piece to form two clusters that are identical except for orientation, being located in mirror-symmetry and rotated 90 degrees from each other about the central axis shown.
