THREE-DIMENSIONAL CONUNDRUM STRUCTURE Russian patent published in 1998 - IPC

FIELD: entertainment facilities. SUBSTANCE: three-dimensional conundrum can be used for playing and also for educational purposes through playing. It has fastening device with play components secured on fastening device. These components can rotate around center of conundrum structure and relative to each other. Outer surfaces of play components create six faces, each of them is painted in its own color. In addition, conundrum has spherical cover plates which are rigidly fastened on axles of fastening device. Also provided are filling and spring-biased load-carrying members with slots, and stationary play component on which rigidly secured are filling members and one load-carrying member. All play components are made in the form of irregular triangle pyramids with possibility of alternate rotation in six planes crossing in center of conundrum. On their side surfaces they have slots with edges restricted by triangular spherical cover plates. Apex of each play component is truncated by triangular spherical cover plates. Spring-biased load-carrying members are simultaneously located in guide members of fastening device created by cover plates with possibility of moving along guide members and in slots of two adjacent play components which are in contact through hypotenuses of bases. Filling members are located in side slots of play components which are free from spring-biased load-carrying members for displacement of play components along slots of spring-biased load-carrying members and filling members. Complicated design of conundrum structure adds to its entertainment. EFFECT: higher efficiency. 24 dwg
