#CMT# #/CMT# The flat ball track comprises an eight-shaped outline, an upper portion (2) and a lower portion (3) made of plastic and having one or more openings (7), and a groove (6) formed in the outer surface. The upper portion has a recess formed in the inner surface, and the lower portion has a pin formed corresponding to the recess, in the inner surface. The pin is inserted into the recess for joining the upper and lower portions with each other. The upper portion comprises two eight-shaped track grooves and two steps with launch sites (8) for the balls. #CMT# : #/CMT# An independent claim is included for a kit comprising a flat ball track and a ball. #CMT#USE : #/CMT# Flat ball track for use as educational device, playground equipment, and exercise equipment. #CMT#ADVANTAGE : #/CMT# The flat ball tracks can be produced quickly in large quantities, and it can be used for various purposes other than educational or fun purposes. Hence an improved flat ball track is provided. The ball track can be manufactured using little plastic material, so that the resources can be saved and weight-saving can be achieved. Hence the ball track can be conveniently and safely used by small children and weakened or disabled persons. The track can be transported and managed easily. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows the schematic plan views of the outer surface of upper portion and lower portion of ball track. 2 : Upper portion 3 : Lower portion 6 : Groove 7 : Opening 8 : Ball launch site #CMT#POLYMERS : #/CMT# The upper portion and the lower portion are independently comprised of plastic material which is selected from a polymer based on acrylonitrile-butadiene styrene, styrene, styrene-acrylonitrile or methyl methacrylate.
