Abstract
Abstract A modular construction system is disclosed comprising a plurality of identical module blocks. Each module block comprises a nominally cubical shape, every face of which is a square with three unit by three unit dimensions. Located at the center of a plurality of the faces of the module block is an indentation having a square shape with one unit by one unit dimensions. Extending outward from the module block are a plurality of projections each having a square cross-sectional shape with one unit by one unit dimensions. Each projection is adapted for insertion into an indentation in the face of another module block thereby forming a constructive assembly.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
137 words
A module for a modular construction block set having modules which interfit to form a desired construction assembly, each module comprising: a cube, wherein a plurality of faces of the cube include an indentation, each indentation being identically shaped and being located concentric to the face; a plurality of projections each extending outward from a face of the cube, wherein every projection is located eccentric to the face from which it extends; every projection has a cross-sectional shape identical to the shape of the indentations in the faces; and every projection has a cross-sectional area smaller than the cross-sectional area of the indentation to permit the projections to be inserted in the indentation; each module being thereby adapted to interfit with another module by inserting a projection of one module into an indentation of the other module.
Claim 2
Dependent Claim
137 words
A module for a modular construction block set having modules which interfit to form a desired construction assembly, each module comprising: a cube, wherein a plurality of faces of the cube include an indentation, each indentation being identically shaped and being located concentric to the face; a plurality of projections each extending outward from a face of the cube, wherein every projection is located eccentric to the face from which it extends; every projection has a cross-sectional shape identical to the shape of the indentations in the faces; and every projection has a cross-sectional area smaller than the cross-sectional area of the indentation to permit the projections to be inserted in the indentation; each module being thereby adapted to interfit with another module by inserting a projection of one module into an indentation of the other module.
Claim 3
Dependent Claim
138 words
A module for a modular construction block set having modules which interfit to form a desired construction assembly, each module comprising: a block of generally cubical shape, wherein every face of the block is a square having side dimensions of three units in length; and a plurality of the faces of the block include a square shaped indentation located concentric to the face and having side dimensions of one unit in length; and a projection extending perpendicularly outward from a face of the block, wherein said projection is located eccentric to the face from which it extends; and said projection has a square cross-sectional shape having a side dimension of one unit in length; each module being thereby adapted to interfit with another module by inserting a projection of one module into an indentation of the other module.
Claim 4
Dependent Claim
138 words
A module for a modular construction block set having modules which interfit to form a desired construction assembly, each module comprising: a block of generally cubical shape, wherein every face of the block is a square having side dimensions of three units in length; and a plurality of the faces of the block include a square shaped indentation located concentric to the face and having side dimensions of one unit in length; and a projection extending perpendicularly outward from a face of the block, wherein said projection is located eccentric to the face from which it extends; and said projection has a square cross-sectional shape having a side dimension of one unit in length; each module being thereby adapted to interfit with another module by inserting a projection of one module into an indentation of the other module.
Claim 5
Dependent Claim
19 words
A module in accordance with claim 2 wherein each projection is either one unit or two units in length.
