Abstract
A traffic control device constructed as a one-piece traffic channelizing device of a plastic material. The device includes a bottom having a plurality of flexible flap elements for receiving and storing a ballast thereon. The flexible flap elements are responsive to a substantial impact to the traffic control device to cause the ballast to be released from the flexible flaps while the device is impacted to a horizontal position adjacent its original position. The device is adapted to mount warning lights and to be stacked including with the warning lights mounted thereto. The stacking of the traffic control devices does not effect the desired action for the flexible flaps.
Claims65
A traffic control device comprising a hollow element having a substantially closed end for mounting the element in a vertical position on a mounting surface when functioning as a traffic control element, the closed end being constructed and defined by means of a plurality of flexible flaps for releasably storing ballast means for stabilizing the hollow element in said vertical position when mounted on the flaps, the flaps being further characterized as being responsive to an impact to the hollow element causing it to be moved from its vertical position to permit any ballast means stored on said flaps to substantially remain in position while being separated from the moving hollow element.
A traffic control element comprising a hollow element having an outer configuration that is constructed and defined to be of a stepped configuration from one end to the opposite end thereof to thereby allow a plurality of the elements to be stacked in a nesting relationship, the hollow element having a substantially closed end for mounting it in a vertical position with a mounting surface to function as a traffic control element, the closed end being constructed and defined with a plurality of flexible, segmented flap elements constructed with the hollow element for substantially closing said end of the hollow element, the segmented elements being adapted to receive ballast means for stablizing the hollow element when the hollow element is arranged in said vertical position, the flexible, segmented flap elements being further characterized as being responsive to a substantial impact to the hollow element so as to permit any ballast means mounted thereon to be separated therefrom while causing the hollow element to be moved in response to a substantial impact from its vertical traffic controlling position.
A traffic control element as defined in claim 11 or 14 wherein the hollow element is constructed and defined from a flexible material.
A traffic channelizer comprising a hollow element having an outer configuration that is constructed and defined to be of a stepped configuration from one end to the opposite end thereof, the smaller dimension of the stepped hollow element having a substantially closed end for mounting the element in a vertical channelizing position with a mounting surface, said closed end being constructed and defined with a plurality of spaced, flexible elements constructed integrally with the hollow element for substantially closing said end of the hollow element, the flexible elements being adapted to receive means for stabilizing the element in said vertical position and being responsive to a substantial impact to the hollow element so as to release any stabilizing means therefrom while permitting the hollow element to be moved from its vertical position while being separated from the stabilizing means, and means constructed and defined for mounting a warning light to the hollow element adjacent the top side thereof.
A traffic control device comprising a hollow element having a substantially closed end for mounting the element in a vertical position on a mounting surface when functioning as a traffic control element, the closed end being constructed and defined by means of a plurality of flexible flaps for releasably storing ballast means for stabilizing the hollow element in said vertical position when mounted on the flaps, the flaps being further characterized as being responsive to an impact to the hollow element causing it to be moved from its vertical position to permit any ballast means stored on said flaps to substantially remain in position while being separated from the moving hollow element, and means constructed and defined for mounting a warning light to the hollow element in a non-rotatable position including when the hollow element has responded to a substantial impact.
