Abstract
A geometric construction set is described having a number of blanks where each blank includes four contiguous triangular sections. The two outer triangular sections each have two edges at the peripheral edge of the blank and the remaining two inner triangular sections having only one edge at the peripheral edge of the blank. Each outer triangular section has a connector that is mateable with a connector on each of the inner triangular sections. The blanks are designed to facially interconnect with other matching blanks allowing the construction of a large variety of triangular polyhedra.
Claims21
A construction blank, a plurality of which are connectable together for constructing solid polyhedrons comprising:
- a planar sheet of a semi-rigid material, said sheet being divided into four triangular sections by three score lines along which said sheet is bendable, said triangular sections including two outer triangular sections and two inner triangular sections and each section including a plurality of vertices, each of said inner triangular sections having a first side formed on a score line in common with an outer triangular section, a second side formed on a score line in common with the other inner triangular section and a third side on a peripheral edge of said blank, each of said outer triangular sections having two sides on respective peripheral edges of said blank and each of said outer triangular sections including a first connector and each of said inner triangular sections including a second connector contained within said inner triangular section, said first connectors being of a type mateable with said second connectors.
A construction blank, a plurality of which are connectable together for constructing solid polyhedrons comprising:
- a planar sheet divided into four contiguous triangular sections by three score lines along which said sheet is bendable, said triangular sections including two outer triangular sections and two inner triangular section, each inner triangular section including a plurality of vertices wherein each of two of said vertices forms a common vertex of three of said triangular sections, and each of said outer triangular sections including a first connector and each of said inner triangular sections including a second connector contained within said inner triangular section, said first connectors being of a type mateable with said second connectors.
A construction set of a plurality of blanks connectable together for constructing solid polyhedrons, each of said blanks comprising:
- a planar sheet of a semi-rigid material said sheet being divided into four triangular sections by three score lines along which said sheet is bendable, said triangular sections including two outer triangular sections and two inner triangular sections and each section including a plurality of vertices, each of said inner triangular sections having a first side formed on a score line in common with an outer triangular section, a second side formed on a score line common with the other inner triangular section and a third side on a peripheral edge of said blank, each of said outer triangular sections having two sides on respective peripheral edges of said blank and each of said outer triangular sections including a first connector and each of said inner triangular sections including a second connector contained within said inner triangular section, said first connectors being of a type mateable with said second connectors.
