Abstract
A mat with puzzle function is a four-sided pad. Each side has a tooth part with a succession of teeth. At least two cutting lines divide the mat into four blocks, in such a way that each block has an assembling part with the complementary shape to connect with others. The block of each mat can engage with another block of the mat to form a puzzle mat set.
