Abstract
Abstract An educational toy device comprising multiple groups of cubes wherein each group is interconnected by means of a double hinge and each cube in each group is also connected by means of a double hinge thereby permitting any number of cube combinations for forming various configurations. Each of the cubes in each group is provided with a selected numeral on each of its six faces in a manner whereby the numerical sum on the faces of at least any pair of cubes adjacent another pair along a common line of symmetry is the same regardless of the various cube combinations.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
181 words
An educational toy device comprising a plurality of cubes arranged into a plurality of cube groups, a double hinge interconnecting adjacent pairs of said cubes in each said group and further interconnecting adjacent pairs of said cube groups, said cube double hinges being so arranged as to permit each of said cubes in each said group to pivot in a first plane along each of a pair of cube first edges, said cube group double hinges being so arranged as to permit each of aid cube groups to pivot in a second plane perpendicular to said first plane along each of a pair of second cube edges, and each face of each said cube being provided with a selected numeral thereon of one of four different numerals in a manner whereby the numerical total on the faces of at least any pair of said cubes adjacent another pair along a common plane of symmetry is the same regardless of the relative position of said faces of each cube to each other in one group or in other ones of said groups.
Claim 2
Dependent Claim
181 words
An educational toy device comprising a plurality of cubes arranged into a plurality of cube groups, a double hinge interconnecting adjacent pairs of said cubes in each said group and further interconnecting adjacent pairs of said cube groups, said cube double hinges being so arranged as to permit each of said cubes in each said group to pivot in a first plane along each of a pair of cube first edges, said cube group double hinges being so arranged as to permit each of aid cube groups to pivot in a second plane perpendicular to said first plane along each of a pair of second cube edges, and each face of each said cube being provided with a selected numeral thereon of one of four different numerals in a manner whereby the numerical total on the faces of at least any pair of said cubes adjacent another pair along a common plane of symmetry is the same regardless of the relative position of said faces of each cube to each other in one group or in other ones of said groups.
Claim 3
Dependent Claim
38 words
The device according to claim 1 wherein four of said groups is provided, each said group having four cubes and said faces of each cube having a numeral between 1 and 4 wherein said numerical total equals 10.
Claim 4
Dependent Claim
29 words
The device according to claim 2 wherein the numerical total on the faces of said cubes lying along a diagonal across said cube groups is also equal to 10.
Claim 5
Dependent Claim
124 words
The device accOrding to claim 3 wherein each said double hinges for said cubes in each said group comprises a first hinge strip and a pair of second hinge strips each, extending between alternate ones of said pair of cube first edges on adjacent cubes, and wherein each of said double hinges for said cube groups are located at alternate ends of each pair of adjacent groups, said cube group hinges comprising a third hinge strip and a pair of fourth hinge strips each extending between alternate ones of said pair of cube second edges in adjacent groups, whereby each of said cubes and each of said cube groups may be pivoted in each of two directions in their respective first and second planes.
