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 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 radially outwardly and axially downwardly tapering 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 skirt portion having a curved portion adjacent the bottom edge of the drum diametrically opposite the flat side, the stiffening ribs progressively increasing in size and radial extent of protrusion from the skirt portion from the approximate midpoint of the curved portion to the protruding corners to create a substantially uniform diameter offset around the drum toward the flat side of the skirt portion, whereby when the ballasting collar is placed over the drum, the stiffening ribs will cause the ballasting collar to be slightly offset from the axial center of the drum in the direction of the flat side.

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.

20. 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 to resist pull out of the drum from a ballasting collar adapted to be inserted over the drum, 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, a plurality of circumferentially spaced radially outwardly and axially downwardly tapering stiffening ribs integral with the skirt portion, the skirt portion having a flat side with outwardly protruding corners adjacent a bottom edge of the drum, the skirt portion having a curved portion adjacent the bottom edge of the drum diametrically opposite the flat side, and the stiffening ribs progressively increasing in size and radial extent of protrusion from the skirt portion from the approximate midpoint of the curved portion around the skirt portion to the protruding corners to create a substantially uniform diameter offset around the drum toward the flat side of the skirt portion, wherein none of the ribs are on the flat side of the skirt portion.
