Patent ID: 7520694

Claim:
A traffic control device comprising: a round adapter tube of a flexible material joined co-axially within a round, vertically oriented lower tube of a rigid material, the lower tube fixedly supported in a ground surface, the adapter tube further joined co-axially with a rigid upper tube having a motorist recognizable indicia; an upper edge of the lower tube spaced apart from a lower edge of the upper tube by between one and five inches of exposed length of the adapter tube; a rigid finger of the lower tube positioned within an opening in the adapter tube, the rigid finger configured and positioned to abut an edge of the opening during upward axial motion, and during rotational motion, of the adapter tube thereby preventing disengagement of the adapter tube from the lower tube; the rigid finger further configured and positioned so that the edge of the opening is flexibly movable over the rigid finger during downward axial motion of the adapter tube thereby enabling disengagement of the opening of the adapter tube from the rigid finger; whereby upon an impact with the upper tube, the adapter tube bends to enable the upper tube to move from a starting vertical position to a horizontal position and thereafter back to the vertical position as the flexible adapter tube rebounds.
