ABSTRACT:
A slotted and grooved construction toy of the type having a plurality of flat bodies with slots interlocking with other flat bodies. The flat bodies have a plastic foam core in combination with a laminated surface. The foam core is a semi-rigid and compressible material which is resilient and durable after repeated use. The laminate is a durable and scratch resistant material that will provide a compressible surface to the foam core. The grooves provide a channel to guide and support the interlocking flat bodies of the construction toy, while allowing a firm, tight connection between the flat bodies and providing a countervailing barrier to shearing stress.
