Abstract
Abstract An educational and entertaining device comprising a set of geometrically identical or proportional elements, each of which includes a plurality of coded indicia bearing surface portions with at least one numeral on each surface portion, the number of elements in said set and the number of said surface portions being identical and at least four in number, said numerals being so related to said coding indicia that if the elements are arrayed such that a differently coded surface portion of each of the elements is disposed for viewing, regardless of which coded surface portion of which element is so disposed, the sum of the numerals on the so disposed surface portions is a constant.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
156 words
A device of the type described comprising a set of geometrically identical elements, each element including a plurality of indicia bearing surface portions, the number of elements in said set and the number of said surface portions being identical and at least four in number, the indicia on each said surface portion being in the form of a coding indicium and at least one numeral, said coding indicium being taken from a set of coding indicia equal in number to said number of elements and surface portions with each surface portion of each element bearing a different coding indicium, said numerals being so related to said coding indicia that if the elements are arrayed such that a differently coded surface portion of each of the elements is disposed for viewing, regardless of which coded surface portion of which element is so disposed, the sum of the numerals on the so disposed surface portions is a constant.
Claim 2
Independent Claim
156 words
A device of the type described comprising a set of geometrically identical elements, each element including a plurality of indicia bearing surface portions, the number of elements in said set and the number of said surface portions being identical and at least four in number, the indicia on each said surface portion being in the form of a coding indicium and at least one numeral, said coding indicium being taken from a set of coding indicia equal in number to said number of elements and surface portions with each surface portion of each element bearing a different coding indicium, said numerals being so related to said coding indicia that if the elements are arrayed such that a differently coded surface portion of each of the elements is disposed for viewing, regardless of which coded surface portion of which element is so disposed, the sum of the numerals on the so disposed surface portions is a constant.
Claim 3
Dependent Claim
13 words
A device as recited in claim 1 wherein said coding indicia are colors.
Claim 4
Dependent Claim
15 words
A device as recited in claim 1 wherein said constant is 76, 1776 or 1976.
Claim 5
Dependent Claim
32 words
A device as recited in claim 1 wherein said elements are constituted by a set of four regular triangular pyramids and said surface portions are the four faces of the respective pyramids.
Claim 6
Dependent Claim
31 words
A device as recited in claim 1 wherein said elements are constituted by a set of five triangular prisms and said surface portions are the five faces of the respective prisms.
Claim 7
Dependent Claim
32 words
A device as recited in claim 1 wherein said elements are constituted by a set of five pentagonal prisms and said surface portions are the five rectangular faces of the respective prisms.
Claim 8
Dependent Claim
50 words
A device as recited in claim 6 which further includes a container in the form of an elongated pentagonal prism having a window extending along one rectangular face thereof, said container being sized to accept said prisms and display a single face of each of the prisms through said window.
Claim 9
Dependent Claim
31 words
A device as recited in claim 1 where in said elements are constituted by a set of six cubes and said surface portions are the six faces of the respective cubes.
Claim 10
Dependent Claim
65 words
A device as recited in claim 1 wherein said elements are constituted by a set of four rectangular or square cards and said surface portions are constituted by areas adjacent each edge of each card such that the cards can be arrayed either with the areas intended to be viewed contiguous to each other or in a stack with the areas to be viewed superimposed.
Claim 11
Dependent Claim
41 words
A device as recited in claim 1 wherein said elements are constituted by a set of star-shaped polygons and said surface portions are constituted by the points thereof, said set including either five five-pointed star-shaped polygons or six six-pointed star-shaped polygons.
