ABSTRACT:
A knockdown labyrinth framework made up of tubes interconnected to make a base unit which itself combines with three others by way of a connection hub to make up a master square. Each such master square is then connected to other master squares. Vertical tubes join the lower structure to an upper structure which has hanging rods from which is hung a partitioning canvas which traces the path to form the labyrinth. Each tube connects and locks in with the next tube by way of frictional interlock which does not require any tools so that it is easy to set up and knockdown afterward.
