Abstract:
A spherical puzzle comprising, in combination:a first pair of generally semi-spherical portions each defining a quarter section of a sphere and formed of an arcuate face and a pair of perpendicular planar faces, the planar faces including a first planar face with a T-shaped groove formed between the arcuate outer face and a second planar face along a central extent thereof, the second planar face including a T-shaped protrusion formed between the arcuate outer face and the T-shaped groove;a second pair of generally semi-spherical portions each defining a quarter section of a sphere and formed of an arcuate face and a pair of perpendicular planar faces, the planar faces of the second pair of generally semi-spherical portions including a first planar face with a first T-shaped groove formed between the arcuate outer face and a second planar face along a central extent thereof, the second planar face including a second T-shaped groove formed between the arcuate outer face and the first T-shaped groove;a central portion including a rectangular bar with a first length equal to a diameter of the semi-spherical portions and a first width, a square plate integrally coupled to a central extent of the rectangular bar in coplanar relationship therewith and having a second length about 1/3 that of the rectangular bar and a second width three times that of the rectangular bar, a cut out formed therein between side faces of the square plate and the rectangular bar for defining a plurality of guides, and a pair of T-shaped protrusions with the second width integrally coupled to opposed faces of the square plate and extending therefrom in perpendicular relationship with the guides; anda pair of generally disk-shaped portions each with a pair of parallel, planar faces with a periphery formed therebetween defined by a linear edge and a semicircular edge, each disk-shaped portion including a pair of T-shaped protrusions formed on each of the planar faces thereof and a T-shaped protrusion formed in a central extent of the linear edge in perpendicular relationship with the T-shaped protrusions of the disk-shaped portions;whereby the T-shaped protrusions of the central portion are releasably engaged with the T-shaped grooves of the disk-shaped portions to define an elongated protrusion formed of the guides and T-shaped protrusions of the disk-shaped portions, the T-shaped grooves of the first pair of generally semi-spherical portions are releasably engaged with the first T-shaped grooves of the second pair of generally semi-spherical portions such that the second T-shaped grooves are aligned with the associated T-shaped groove of the first pair of generally semi-spherical portions to define an elongated groove, wherein the elongated groove is releasably engaged with the common protrusion.
