A
Abstract:
A tile consists of two outer layers and an inner layer arranged in parallelism. One of the outer layers is larger than the other outer layer, while the smaller outer layer is larger than the inner layer. A slot surrounds the edges of the inner layer and has a width at least equal to the thickness of the smaller outer layer. Cooperating coupling devices are provided on the smaller outer layer and the inner layer so that when two similar tiles are assembled with the smaller outer layer of one tile extending into the slot of the other tile, the coupling device on the inserted smaller outer layer cooperates with that on the adjacent inner layer to inhibit movements of the tiles in directions other than that to move the coupling devices apart.
