Patent ID: 7192329

Claim:
A multi-facet decoration assembly, comprising multiple hexagonal grates and pentagonal grates, wherein: each hexagonal grate is equilateral, slightly dished toward the center of the hexagonal grate, with a hole in the center, and a catch pin and a slot pin alternately arranged near each corner and on the underside of the hexagonal grate; each pentagonal grate is also equilateral, slightly dished toward the center of the pentagonal grate, with a hole in the center, and a catch pin and a slot pin alternately arranged near each corner and on the underside of the pentagonal grate; each catch pin on one hexagonal grate is to correspond with a slot pin on another hexagonal grate, or a slot pin on one pentagonal grate; and each slot pin on one hexagonal grate is to correspond with a catch pin on another hexagonal grate or a catch pin on one pentagonal grate, so that all catch pins and slot pins on all polygonal grates are locked against each other in order to build a hollow ball-shaped structure; wherein each slot pin is engaged with a catch pin in the interior of the hollow ball-shaped structure, and the adjacent hexagonal grates or pentagonal grates join together edge to edge to make the slot pins and catch pins invisible from the outside of the multi-facet decoration assembly.
