Assembly kit for creating three-dimensional formations, especially toy structures from prefabricated modular building blocks

摘要

An improved set of toy building or construction blocks, each block having a substantially square cross-section and a generally rectilinear configuration. Incorporated into the structure of the individual toy blocks are transversely oriented slots, grooves and protrusions of predetermined size and location. The slots, grooves and protrusions of pre-determined size and location are of either male or female configuration disposed medially along one or more plane of each block. When the male protrusion of one block is introduced perpendicular to the female slot of one end of another block, a frictional engagement is created resulting in a right angle. When the male protrusion of one block is introduced to the female slot in a linear fashion the result is a line segment. Joining a plurality of said toy building or construction blocks using various perpendicular connections in conjunction with linear connections results in the stable formation of construction or geometric structures without the use of fasteners or other connecting elements.

主权项

1. An elongated toy building block comprising: a. a center male connection point located at the center of the block, comprising a narrow portion having a certain thickness; b. a first end connection point at a first end of the block; c. a second end connection point at a second end of the block; d. a first off-center connection point disposed between the first end and center, and a second off-center connection point disposed between the second end and center, each off-center connection point comprising apertures configured to receive a male protrusion and frictionally engage the protrusion, wherein engagement between the connection points and mating connection points of additional blocks is accomplished using a friction fit wherein the mating connection points are not engaged by an angled corner abutment, and wherein the elongated toy building block is configured as a single-piece construction, incapable of being disassembled into smaller component parts; wherein the first end connection and second end connection are transversely opposite to the center connection point.
