Coupling Structure for Assemblable Soccer Ball Puzzle

Abstract

Disclosed herein is an assemblable soccer ball puzzle. The soccer ball puzzle includes 20 regular hexagonal puzzle pieces, 12 regular pentagonal puzzle pieces, and support wings having female and male fitting parts. When the puzzle pieces are assembled using the support wings through an insertion method, the inserted puzzle pieces are in tight contact with each other without being loosened, thus providing a soccer ball puzzle having a perfect spherical shape. The soccer ball puzzle is used for various purposes, for example, an advertising ornament, a mobile, or a money box.

1 . A coupling structure for a 32 polyhedron soccer ball puzzle, having 12 regular pentagonal panels having a male fitting part extending outwards from a center of an edge of each of the panels a predetermined length and having a predetermined width and a female fitting part having a fastening groove having a length corresponding to a width of the male fitting part, and 20 regular hexagonal panels each having an edge which has the same length as the edge of each of the regular pentagonal panels, a male fitting part extending outwards from a center of the edge of each of the panels a predetermined length and having a predetermined width, and a female fitting part having a fastening groove having a length corresponding to a width of the male fitting part, the soccer ball puzzle being assembled by fitting the male fitting part of each of the regular pentagonal panels and the regular hexagonal panels into the corresponding female fitting part thereof, wherein
 the soccer ball assembled using the regular pentagonal panels and the regular hexagonal panels comprises:   a folding line formed at a junction between each of the male and female fitting parts provided on respective edges of the regular pentagonal panels and the regular hexagonal panels and each of the regular pentagonal panels and the regular hexagonal panels in such a way as to be located along each of the edges;   a trapezoidal support wing providing restoring force when folded along the folding line formed on each of the edges of the regular pentagonal panels and the regular hexagonal panels; and   a male fitting part or a fastening groove of a female fitting part provided in the support wing, so that when the male fitting part and the female fitting part provided on each of the edges of the regular pentagonal panels and the regular hexagonal panels engage with each other through an insertion method, the male fitting part and the female fitting part are firmly supported by the restoring force of the folded support wing.
