Technical Field
This invention relates generally to a traffic cone and more particularly for an improved triangle base traffic cone with polygonal cone body.
State of the Art
According to the Manual on Uniform Traffic Control Devices (MUTCD), “Cones shall be predominantly orange and shall be made of a material that can be struck without causing damage to the impacting vehicle. For daytime and low-speed roadways, cones shall be not less than 18 inches in height. When cones are used on freeways and other high-speed highways or at night on all highways, or when more conspicuous guidance is needed, cones shall be a minimum of 28 inches in height. For nighttime use, cones shall be retroreflectorized or equipped with lighting devices for maximum visibility. Retroreflectorization of cones that are 28 to 36 inches in height shall be provided by a 6-inch wide white band located 3 to 4 inches below the 6-inch band. Retroreflectorization of cones that are more than 36 inches in height shall be provided by horizontal, circumferential, alternating orange and white retroreflective stripes that are 4 to 6 inches wide. Each cone shall have a minimum of two orange and two white stripes with the top stripe being orange. Any non-retroreflective spaces between the orange and white stripes shall not exceed 3 inches in width.”
Conventional traffic cones have a square base and circular conical shape body. Some cones include reflective portions of the circular conical shaped body. The cones are heavier and the reflective portions are limited.
Accordingly, there is a need in the field of traffic cones for an improved traffic cone.
The present invention relates to a traffic cone with a triangle base and polygonal cone shaped cone body.
An embodiment includes a traffic cone comprising a base; and a cone body coupled to the base and extending from a top side of the base, wherein the cone body comprises five or more surfaces forming a polygonal cone shape.
Another embodiment includes a traffic cone comprising: a triangular base; a cone body having eight surfaces forming an octagonal cone shape coupled to the triangular base, wherein the cone body extends from a top side of the triangular base; at least one reflective member coupled around a perimeter of the cone body; and feet coupled to a bottom side of the triangular base.
Yet another embodiment includes a method of using a traffic cone comprising: placing a cone in a roadway, wherein the cone comprises a triangular base; a cone body coupled to the base and extending from a top side of the triangular base and at least one reflective member coupled around a perimeter of the cone body, wherein the cone body comprises five or more surfaces forming a polygonal cone shape; reflecting light from the at least one reflective member from various angles corresponding to the angle of the surfaces of the cone body; and directing traffic by use of the cone.
The foregoing and other features and advantages of the present invention will be apparent from the following more detailed description of the particular embodiments of the invention, as illustrated in the accompanying drawings.
Embodiments of the present invention relate to a traffic cone with a triangle base and polygonal cone shaped cone body.
As shown in
The polygonal shape of the cone body 14 allows for light be incident on the cone at varying angles, and with a flat surface, it provides a larger surface area of reflective member 18, thereby making it more visible, particularly at night. Because of the polygonal shape, the traffic cone 10 may be placed in any orientation and the varying angles of the surfaces 16 will provide a reflective surface to light from vehicles to more easily reflect a larger surface area of the reflective member 18 in order to alert a driver of the traffic cone and the impending traffic roadway condition, closure, or warning. This is superior to a round cone that only provides a small rounded surface wherein the light is reflected in various angles from the surface, resulting in lower viewing ability compared to embodiments of the present invention. Additionally, a cone with four or less sides would require greater care in locating the cone to direct traffic because it would be easy to orient the cone where a surface having a reflective member not in an orientation to accurately reflect the light incident on the cone by a vehicle and therefore is not easily viewable by a driver of a vehicle.
Advantages of the traffic cone 10 include:
The functionality of the traffic cone 10 includes:
The dynamic property of the traffic cone 10 includes:
The traffic cone 10 may have certain material requirements. For example, and without limitation, the traffic cone may include some or all of the following material requirements. Cones shall conform to the requirements of the MUTCD, shall be NCHRP 350 approved and shall be orange rubber or plastic. Cones shall have a maximum weight of 9 kg, including ballast. Standard cones shall be approximately 710 mm in height with a minimum conical bottom width of 250 mm. Standard cones shall have two horizontal circumferential stripes of white reflective sheeting, the upper a minimum of 150 mm wide, with the upper edge 75 to 100 mm from the top of the cone, and the lower a minimum of 100 mm wide with the upper edge approximately 50 mm below the upper stripe.
Tall cones shall be approximately 915 mm in height with a minimum conical bottom width of 250 mm. Tall cones shall have two horizontal circumferential stripes of white reflective sheeting, the upper a minimum of 150 mm wide, with the upper edge 75 to 100 mm from the top of the cone, and the lower a minimum of 100 mm wide with the upper edge approximately 50 mm below the upper stripe.
Extra tall cones shall be a minimum of 1050 mm in height with a minimum conical bottom width of 175 mm. Extra tall cones shall have a minimum of four horizontal circumferential stripes of reflective sheeting from 100-150 mm wide, of alternating orange and white starting with orange on the top. The upper edge of the sheeting shall be 100 mm from the top of the cone. Non-reflective spaces between the stripes shall not exceed 75 mm wide. Reflective sheeting shall conform to '730-05 Reflective Sheeting ASTM Type I or ASTM Type III. Reflective sheeting shall be firmly bonded to the cone with adhesive.
Embodiments of the present invention may also include a method of using a traffic cone. The method includes placing a cone in a roadway, wherein the cone comprises a triangular base; a cone body coupled to the base and extending from a top side of the triangular base and at least one reflective member coupled around a perimeter of the cone body, wherein the cone body comprises five or more surfaces forming a polygonal cone shape; reflecting light from the at least one reflective member from various angles corresponding to the angle of the surfaces of the cone body; and directing traffic by use of the cone.
The method may further includes additional steps, such as, but not limited to, comprising weighting the cone down with plurality of weighted feet; directing traffic away from a particular lane of traffic in response to using the traffic cone, wherein the at least one reflective member is yellow in color; supporting roadway closures, or ramp closure in response to using the traffic cone, therein the at least one reflective member is red in color; and holding a traffic cone in response to grasping recessed hand grooves of the traffic cone, wherein the recessed hand grooves are located on a top portion of the cone body.
The embodiments and examples set forth herein were presented in order to best explain the present invention and its practical application and to thereby enable those of ordinary skill in the art to make and use the invention.
