FOLDING TRAFFIC CONE 450mm HIGH Traffic cones, also called pylonswitches’ hats,[1][2] road coneshighway conessafety cones, or construction cones, are usually cone-shaped markers that are placed on roads or footpaths to temporarily redirect traffic in a safe manner. They are often used to create separation or merge lanes during road construction projects or automobile accidents, although heavier, more permanent markers or signs are used if the diversion is to stay in place for a long period of time. Traffic cones were invented by Charles D. Scanlon, an American who got the idea while working as a painter for the Street Painting Department of the City of Los Angeles.[3] The patent for his invention was granted in 1943.[4] Traffic cones were first used in the United Kingdom in 1958, when the M6 motorway opened. These traffic cones were a substitute for red lantern paraffin burners being used during construction on the Preston Bypass.[5] In 1961, David Morgan of BurfordOxfordshire, UK believes that he constructed the first experimental plastic traffic cones, which replaced pyramid-shaped wooden ones previously used.[6] In the United States on May 1, 1959 the Pacific Gas and Electric Company in Oakland, California adopted the policy of placing the orange safety cones at left front and the left rear corners of their service trucks while parked on the street to increase visibility and safety for the workers. This policy was implemented as the result of a suggestion by their employee, Russell Storch, a cable splicer. He was awarded $45 for his suggestion. This policy is still in use today.[7] Although originally made of concrete, today’s versions are more commonly brightly colored thermoplastic or rubber conesRecycled PVCs from bottles can be used to create modern traffic cones.[8] Not all traffic cones are conical. Pillar-shaped movable bollards fulfill a similar function.

Indoor and non-traffic use

Cones are used to lay out courses for autocross competitions. Cones are also frequently used in indoor public spaces to mark off areas which are closed to pedestrians, such as a restroom being out of order, or to denote a dangerous condition, such as a slippery floor. They can be used on school playgrounds to limit areas of a playing field, and on ice rinks to define class, private party, or private lesson areas. Some of the cones used for this purpose are miniature, as small as 5 cm (2.0 in) tall, and some are disposable full-size cones made of biodegradable paper. Being distinctive, easily portable and usually left unguarded, traffic cones are often stolen. Students are frequently blamed, to the extent that the British National Union of Studentshas attempted to play down this “outdated stereotype”.[10] The term “road cone” is also commonly used in the construction industry as a lighthearted insult. It is used to describe an individual who spends most of the day just standing still, making no attempt to get involved in the work they should be doing.
