Connectable polygonal construction modules

Abstract

Polygonal construction modules are capable of being connected together by their edges and by their faces to create many different three-dimensional shapes. Each module has a generally planar body with edge faces, a top face and a bottom. Each edge face has a plurality of outwardly projecting fingers designed to provide a snap-together lateral interlock between fingers of adjacent modules while permitting hinging or rotation between modules on an axis parallel to the side face. Projecting upwardly from each top face is at least one annular connector element for establishing a friction fit with a like connector element in face-to-face interlocking engagement. The connector element includes a series of projections arranged in a uniform circular array, each projection being segmental in shape with radial side walls. The space between each pair of projections is the same shape and size as each projection whereby to snugly receive and hold a projection of a like connector element solely by frictional contact between engaging projection side walls. The body portion directly beneath each connector element is thin relative to the height and width of each projection to thereby provide the array as a whole with substantially greater flexibility than the intrinsic flexibility of each projection. In this manner, dimensional inaccuracies of the projections are accommodated when engaged with a like connector element, thereby enhancing the firmness of frictional contact between engaging projection side walls.
