Traffic control element and method of erecting and stabilizing same
First Claim
1. A base element for a two-piece traffic control element comprising a molded plastic base element having a dome-like external shape and pre-selected hollow configuration for storing a pre-selected quantity of ballast means within the hollow, and having an opening for introducing ballast means within the hollow, ballast means comprising loose, particulate material packed for filling the hollow portion of the base element and means for securing the base opening to prevent any loss of the ballast means from the base element and to maintain the ballast means in place within the base element, the thus defined and ballasted base element permitting reusability of the base element, including after being subjected to the weight of a motor vehicle thereon traveling thereover.

Abstract
A two-piece, detachable traffic channelization element having an improved base element. The base element has a low profile, dome-like configuration with a ballast storage chamber. The storage chamber may be completely filled with a sand ballast and sealed in its storage condition by a cover secured to the chamber. The base element is molded of a resilient crush resistant plastic so that when it is fully ballasted, need not be ballasted again, and which low profile base can be traveled over by motor vehicles without engaging the base. The detached base, filled with ballast, can be continuously traveled on by motor vehicles, including loaded trucks, without damaging the base element and rendering it useless and the need to be replaced.

- 1. A base element for a two-piece traffic control element comprising a molded plastic base element having a dome-like external shape and pre-selected hollow configuration for storing a pre-selected quantity of ballast means within the hollow, and having an opening for introducing ballast means within the hollow, ballast means comprising loose, particulate material packed for filling the hollow portion of the base element and means for securing the base opening to prevent any loss of the ballast means from the base element and to maintain the ballast means in place within the base element, the thus defined and ballasted base element permitting reusability of the base element, including after being subjected to the weight of a motor vehicle thereon traveling thereover.
- 8. A base element for a two-piece traffic control element having a hollow element and a base element adapted to be releasably interlocked for functioning as a traffic control element, the improved base element comprising a molded, resilient plastic base element having a pre-selected hollow configuration for storing ballast means within the hollow and having an opening for receiving and storing of ballast means within the hollow, and a lockable cover adapted for closing the opening of the base element, the periphery of the opening for the base element and the periphery of the cover being constructed and defined in a complementary configuration to be locked together for securing the ballast means therein.
- 11. A base element for a two-piece, attachable and detachable traffic control element comprising a base element molded from a crush resistant plastic having a low profile, pre-selected dome-like configuration with a hollow ballast storing chamber accessible through a filling aperture on one side thereof and cover means sized to be interfitted with said filling aperture for completing the enclosure of the ballast storing chamber, the peripheries of the filling aperture and the cover means being constructed and defined for releasably interlocking the cover means to the base element to enclose the ballast storing chamber, including when storing ballast therein, the ballast material selected to be stored within said chamber being characterized as a flowable mass of loose particles that are relatively incompressible and adapted to fully occupy the volume of said chamber so that when the base is completely filled with said selected ballast material, it is enclosed in an essentially leak proof fashion by the interlocked cover means, whereby the completely ballasted base element may be repeatedly traveled over, including by motor vehicles, without the destruction, tearing or bursting of the base element due to being traveled over and the low profile, dome-like shape is selected to allow a motor vehicle to travel over the top of the base element without engagement with the underside of motor vehicles.
- 13. A base element for a two-piece traffic control element comprising a base element having a dome-like shape with a pre-selected hollow configuration for storing ballast means within the hollow and an opening for receiving ballast means therethrough to be stored therein, and cover means adapted to be interfitted with the base element at the opening thereof to close the opening and to be locked thereto, and thereby securing any ballast means stored therein, including after the traffic control element is impacted by a motor vehicle, the periphery of the base element having a configuration adapted to be releasably interlocked with a hollow element for the two-piece traffic control element.
- 23. A traffic channelization element comprising a hollow element having a barrel-like configuration adapted for traffic channelization signaling purposes, and a base member, the hollow element and the base member being adapted to be assembled and disassembled to one another and when assembled function for traffic channelization purposes whereby upon impact, the hollow element will be separated from the base member to thereby minimize damage thereto and allowing ready re-assembly of the hollow element and base member for reusability, the base member being further characterized as having an arcuate configuration corresponding to the barrel-like configuration of the hollow element with a bottom surface defined for engaging a mounting surface, the configuration of the base member defining a ballast storing chamber having an opening for receiving ballast means to be loaded within the chamber, the base member including cover means for releasably securing said storing chamber opening and thereby the ballast means within said chamber for preventing loss of the ballast means from the chamber, including when the hollow element is impacted and separated from the base element.

34. A traffic channelization element comprising a hollow element having a barrel-like configuration adapted for traffic channelization signaling purposes, and a base member, the hollow element and the base member being adapted to be assembled and disassembled to one another and when assembled and disassembled to one another and when assembled function for traffic channelization purposes whereby upon impact, the hollow element will be separated from the base member to thereby minimize damage thereto and allowing ready reassembly of the hollow element and base member for reusability, the base member being further characterized as having an arcuate configuration corresponding to the barrel-like configuration of the hollow element with a bottom surface defined for engaging a mounting surface, the configuration of the base member defining a ballast storing chamber for receiving a continuous mass of loose, gritty particles to be loaded within the chamber including completely filling the storage chamber, the base member including cover means for securing the ballast means within said chamber for preventing loss of the stored ballast means from the chamber including when impacted and traveled over.
- 35. A stackable base element for a two-piece traffic channelizing element when the stackable base elements have been disassembled from the other piece of the traffic channelizer, the base element comprising a molded plastic element having a pre-selected hollow configuration for storing ballast means therein and an aperture for introducing ballast means therein, cover means for releasably closing said aperture for introducing the ballast means therein, the bottom surface of the base element including a plurality of dependent elements arranged in a pre-selected pattern for use in stacking over another base element having the same configuration, the base element surface and said dependent elements being complimentarily defined and constructed to interfit with one another in a stacked relationship.
