TheInchworm was a ride-ontoy for children produced by theHasbro Corporation, first introduced in the early 1970s.[1] Inchworm was designed byJoseph M. Burck while he worked forMarvin Glass and Associates. Burck built the first inchworm using his clothes-dryer's hose and tested it with his then-three-year-old son.[2] Ascooter withyellowwheels in the shape of agreencaterpillar wearing a yellowhat, the Inchworm wasjointed under thesaddle so itswheelbase could expand and contract. The wheels were constricted by a ratchet mechanism to rotating forward. As the rider bounced up and down on the saddle, the toy moved forward in a way somewhat resembling aGeometer caterpillar, with the ratcheting wheels making a clicking sound.
