Polyhedral Toy

Abstract

The present invention relates to a polyhedral toy from which fun with a sense of reality is experienced, and that prevents injury because of its lightweight. A polyhedral toy ( 1 ) is an elasticity-having polyhedron, on at least one face of which an extension is provided as an interlock protrusion ( 3 ), and in at least another one face of which an interlock hole ( 7 ) is formed, and the interlock protrusion ( 3 ) and interlock hole ( 7 ) has shapes allowing reciprocally interlocking connection. Furthermore the interlock protrusion ( 3 ) has a constricted portion ( 5 ) reduced in diameter, between a protrusion top portion and a base face ( 2 ), and the interlock hole ( 7 ) has a shape in which an opening portion ( 8 ) is reduced in diameter, compared with the inside of the interlock hole ( 7 ). Inserting the interlock protrusion ( 3 ) into the interlock hole ( 7 ) brings a state in which the opening portion ( 8 ) engages with the constricted portion ( 5 ) to prevent the interlock protrusion ( 3 ) form disengaging from the interlock hole ( 7 ). Additionally, the elastic-material constitution prevents play participants from being injured, and enables building of structures slightly smaller, and to the contrary greater, than those in full-size, making it possible to enjoy more interesting play with a sense of more convincing reality.

       5 . A polyhedral toy as set forth in  claim 1 , characterized in that said constricted portion of said interlock protrusion is formed at the juncture of said interlock protrusion with the base face.
