  • Patent number: 4003144
    Abstract: An educational alphabet block formed of a polymeric material and having the configuration of a cube with a square recess on each face for receiving a removable chip. Each face of the block also defines an aperture. The aperture reduces the weight of the block without reducing its strength and also provides a means for inserting rods into the block.The chip is fabricated of a polymeric material and includes opposed flexible lips about a groove around the perimeter of the chip. The flexible lips facilitate the ease with which chips are inserted and removed from a recess in the face of the block. The groove enables the lip of one chip to be used to remove another chip secured in a recess in the block.The chip may have appropriate legends such as letters of the alphabet, numerals or scenes printed on one or both faces. Alternatively, the chips may define a central aperture for the insertion of rods into the blocks.
