Abstract
A vehicular traffic control device having a body formed by a hollow, elongated shell with a central domed ridge, vertically curved side walls and laterally extending, pavement engaging footings. The shell is made from molded plastic so as to be light weight, highly portable and stackable. Friction pads are provided for the bottom pavement engaging surfaces of the footings and spaced bump reflectors are located on the top surfaces thereof. The shell may be reinforced by cross ribs and is provided with hinge devices for connecting the devices in tandem.
Claims19
A light weight portable vehicular traffic safety control device comprising in combination;
- an elongated hollow shell having a central domed ridge extending the full length thereof and including terminal ends and an inside concave surface,
- said shell including opposite vertically curved longitudinal side panels terminating in laterally extending footing members extending the substantial length of said shell,
- said footing members having substantially horizontally extending walls connected to said side panels with pavement engaging bottom surfaces thereon and top horizontal surfaces adapted for engagement with an approaching vehicle tire,
- the inside surface of said hollow shell being substantially unobstructed and forming a cavity extending substantially the full length of said shell,
- whereby the weight of a vehicle on said top surface enhances the frictional engagement between the footing and the pavement and a plurality of said shells may be stacked in nesting relation.
A vehicular traffic safety control device comprising in combination;
- a rigid light weight elongated hollow shell body comprising a thin molded plastic material, said shell having a central domed ridge extending the full length of said shell with opposite vertically curved longitudinal side panels terminating in laterally extending footing members extending the substantial length thereof,
- top horizontal surfaces on said footing members extending the substantial length of said shell adapted for engagement with an approaching vehicle tire,
- rigid metallic cross ribs connected to said shell and located at spaced intervals along the length thereof,
- elastomeric friction pads adhesively bonded to the bottom surface of said footing members for enhancing frictional engagement with the pavement,
- a plurality of longitudinally spaced protrusions on said top surface of the footing members for producing vibrations when contacted by the tire of a moving vehicle, said protrusions including light reflecting areas thereon for warning the driver of an approaching vehicle,
- said shell including terminal ends and an inside surface with a metal hinge bar attached thereto and extending the full length thereof, and
- connector members on each end of said hinge bar extending beyond the terminal ends of said domed ridge,
- said connector members being provided with hinge apparatus for pivotally connecting succeeding shells to form a continuous line of control devices.
A light weight portable vehicular traffic safety control device comprising in combination;
