Patent 9980591 was granted and assigned to Skip Hop on May, 2018 by the United States Patent and Trademark Office.
A playmat system includes a series of isosceles right triangle tiles and edge tiles. Advantageously, the triangle shaped tiles and edge tiles have one or of two color or patterns or more. The triangle shaped tiles and edge tiles have complementary edges which allow the triangle tiles to be interlockingly engaged with one another along either hypotenuse edges or like edges to thereby produce a number of different patterns when laid out and interconnected.
