US4875681A — Hingedly connected cubical prisms amusement and d…

Claim 1

Independent Claim 185 words

An amusement and display device comprising at least eight distinct elements each of said elements being of regular prismatic shape and having sides, edges and corners wherein each of said elements is interconnected to an adjacent element by flexing joining means provided along an edge thereof, at least two of said elements being connected along two separate edges to two adjacent elements and at least one of said elements being connected along three separate edges to three adjacent elements, wherein said elements are cubical prisms formed by interfitting two identical units of U-shaped profile mutually angularly offset by 90° and facing one another with their open ends and said joining means is a flexure web, an edge grip of one of said joining means being positioned adjacent an inner wall of one of said U-shaped units with its associated web overlying an edge adjacent thereto whereby when one of said U-shaped units is interfitted with an identical U-shaped unit the edge grip is retained within the body of the formed cubical element with its associated web clamped between adjacent interfitted edges of said interfitted units.

Claim 2

Dependent Claim 185 words

An amusement and display device comprising at least eight distinct elements each of said elements being of regular prismatic shape and having sides, edges and corners wherein each of said elements is interconnected to an adjacent element by flexing joining means provided along an edge thereof, at least two of said elements being connected along two separate edges to two adjacent elements and at least one of said elements being connected along three separate edges to three adjacent elements, wherein said elements are cubical prisms formed by interfitting two identical units of U-shaped profile mutually angularly offset by 90° and facing one another with their open ends and said joining means is a flexure web, an edge grip of one of said joining means being positioned adjacent an inner wall of one of said U-shaped units with its associated web overlying an edge adjacent thereto whereby when one of said U-shaped units is interfitted with an identical U-shaped unit the edge grip is retained within the body of the formed cubical element with its associated web clamped between adjacent interfitted edges of said interfitted units.

Claim 3

Claim 9

Dependent Claim 16 words

An amusement and display device according to claim 1 wherein said web is of cloth material.

Claim 10

Dependent Claim 216 words

An amusement and display device comprising: a plurality of cubical prism elements including a first, a second, a third, a fourth, a fifth element, and a sixth element, each element having a plurality of edges and faces; and hinging means for interconnecting the cubical prisms and including: a. a first hinge connected between an edge of said first element and a first edge of the second element; b. a second hinge connected between a second edge of said second element and a first edge of said third element, said first and second edges of said second element being disposed along a common face of said second element; c. a third hinge connected between a second edge of said third element and an edge of said fourth element, said first and second edges of said third element being disposed along different faces; d. a fourth hinge disposed between a third edge of said second element and a first edge of said fifth element, said third edge being disposed along a different face from said common face of said second element; and e. a fifth hinge connected between a second edge of said fifth element and a first edge of said sixth element, said first and second edges of said fifth element being disposed along a common face.

Claim 11

Dependent Claim 216 words

An amusement and display device comprising: a plurality of cubical prism elements including a first, a second, a third, a fourth, a fifth element, and a sixth element, each element having a plurality of edges and faces; and hinging means for interconnecting the cubical prisms and including: a. a first hinge connected between an edge of said first element and a first edge of the second element; b. a second hinge connected between a second edge of said second element and a first edge of said third element, said first and second edges of said second element being disposed along a common face of said second element; c. a third hinge connected between a second edge of said third element and an edge of said fourth element, said first and second edges of said third element being disposed along different faces; d. a fourth hinge disposed between a third edge of said second element and a first edge of said fifth element, said third edge being disposed along a different face from said common face of said second element; and e. a fifth hinge connected between a second edge of said fifth element and a first edge of said sixth element, said first and second edges of said fifth element being disposed along a common face.

Claim 12

Dependent Claim 101 words

The display device of claim 9 wherein said plurality of elements includes a seventh and an eighth element and said hinging means includes: f. a sixth hinge connected between a second edge of said sixth element and a first edge of said seventh element, said first and said second edges of said sixth element being disposed along opposite faces of said sixth element; and g. a seventh hinge connected between a second edge of said of seventh element and a first edge of said eighth element, said first and second edges of said seventh element being disposed along a common face.

Claim 13

Dependent Claim 19 words

The display device of claim 9 wherein said plurality of elements consists of only eight elements and seven hinges.
