Definitions

• This invention relates to building block systems and methods and more particularly to illuminated building block systems and methods.
• Building blocks have been around for generations, and allow children to use their imagination to create a variety of structures. Building blocks have come in many different structural arrangements. Originally, blocks did not interconnect but were merely placed on top of one another to build structures. Later, interconnected blocks such as those sold under the LEGO trademark, were developed that allowed children to create interconnected structures.
• the present invention provides a building block system using colored lights that can be interconnected to make a variety of multi-colored, three-dimensional shapes.
• the building block system and method of the present invention employs a variety of building block shapes each of which is preferably formed of a transparent body, and with each building block having at least two electrically conductive connectors, at least one of which is a male connector and at least one other is a female connector. Electrical conductors traverse each body from each connector to the other, with a light emitting diode (LED) connected across each connector. A power source applied to one of the connectors of one of the building blocks permits the LED in that block or any other connected block to be illuminated.
• LED light emitting diode
• each male connector is dimensioned for insertion into each female connector to provide a removable and well secured mechanical and electrical connection between adjoining building blocks.
• each body is generally transparent so as to transmit light outwardly through the body.
• the building blocks preferably include at least the following shapes: rectangles; cylinders; cylinders with one or more 90° bends; a generally "Y" configuration; and the form of a wheel. A wide variety of other shapes may also be used.
• all of the blocks have a common dimension.
• Each male and female connector associated with each block allows electric current to illuminate that single block, or to pass electric current from one building block to the next, or allow a block to be connected directly into a power source. As each additional building block is connected, electric current from a power source is transferred from building block to building block via the mechanically interconnected male and female connectors.
• the external power source comprises a power base container like that disclosed in the above-identified provisional application and described below.
• the container holds direct current batteries that are electrically connected through the container with corresponding male or female connectors to one or more of the blocks in a manner which permits the blocks to be stacked upon the top surface of the container.

• the power base version of the container includes an internal storage area for the blocks.
• the present invention is designed to challenge a child's mental acuity for building different and interesting lighted structures in a safe environment.
• the LEDs utilized in the building blocks are of different colors, to further provide stimulation to a child's imagination.
• the blocks are fabricated of high impact plastic, and the level of electricity used is small so as to not create any potential for a shock hazard.
• each block is capable of illumination without being interconnected with another block, a plurality of individual blocks may be installed upon a platform having appropriate connectors.
