Traffic channelizer devices
First Claim
1. A traffic channelizer device comprising a deformable hollow plastic drum having a side wall and an open bottom, a ballasting collar having an upper portion adapted to be received within the open bottom, and a plurality of circumferentially spaced locking fingers extending radially inwardly from the side wall adjacent a bottom edge of the drum adapted to be received in a radially outwardly facing annular groove in the upper portion of the base for releasably retaining the upper portion of the base within the open bottom, the drum being deformable upon impact by a vehicle to cause the drum to flex sufficiently to become dislodged from the base leaving the base behind.

Abstract
A traffic channelizer device includes a deformable hollow plastic drum that may be ballasted by a drop over ballasting collar or by a base having an upper portion that may be releasably retained within the open bottom of the drum by a plurality of circumferentially spaced radially inwardly extending locking fingers adjacent the bottom edge of the drum that releasably engage a groove in the upper portion of the base. An intermittent stacking rim may be provided at the top of the drum to prevent overstacking of a plurality of such drums. Also the intermittent stacking rim may be used to prevent rotation of a portable sign assembly relative to the drum and keep the portable sign assembly from inadvertently sliding up off the drum top.

25. A traffic channelizer device comprising a deformable hollow plastic drum having a side wall and an open bottom, a radially outwardly and axially downwardly tapering skirt portion adjacent the open bottom for resisting pull out of the drum from a ballasting collar adapted to be inserted over the drum, and a plurality of circumferentially spaced stiffening ribs integral with the skirt portion, the skirt portion having a relatively wide flat side with outwardly protruding corners adjacent a bottom edge of the drum to resist rolling of the drum when tipped on its side, the bottom edge of the drum having a curved portion opposite the flat side, the stiffening ribs progressively increasing in size and radial extent of protrusion from the approximate midpoint of the curved portion to the protruding corners to cause the ballasting collar to be slightly offset from the axial center of the drum in the direction of the relatively wide flat side, the drum being deformable upon impact by a vehicle to cause the drum to collapse sufficiently to permit the skirt portion to pass through the ballasting collar to dislodge the drum from the ballasting collar leaving the ballasting collar behind.

26. A traffic channelizer device comprising a deformable hollow plastic drum having a side wall and an open bottom, a ballasting base having an upper portion adapted to be retained within the open bottom for ballasting the drum, both the open bottom of the drum and the upper portion of the base having a corresponding irregular shape for maintaining a desired orientation of the drum relative to the base, the base having a lower portion that extends radially outwardly beyond the upper portion of the base to provide a flat surface for supporting engagement by the open bottom for the drum off the ground, the base having a bottom, and a plurality of spaced apart ribs on the base bottom all extending in the same direction to form channels beneath the base allowing water to flow through the channels under the base.
- 27. A traffic channelizer device comprising a deformable hollow plastic drum having a side wall and an open bottom, the side wall being stepped inwardly along its axial length to form sequential inward stepped surfaces toward the top of the drum to permit stacking of a plurality of such drums one on top of another, the top of the drum having a stacking rim that protrudes radially outwardly beyond the inner diameter of the uppermost stepped surface of the drum but less than the inner diameter of a second uppermost stepped surface of the drum to prevent overstacking of a plurality of such drums beyond a transition shoulder between the uppermost stepped surface and the second uppermost stepped surface of such drums.
