Title:
DELINEATOR WITH BOUNCEBACK MECHANISM
Document Type and Number:
WIPO Patent Application WO/2011/082024
Kind Code:
A3
Abstract:
Delineators are described that include a delineator body, a ball and socket joint, and a resilient rod. The ball and socket joint is disposed to promote deflection of the delineator body in response to a deflecting force. The resilient rod, which may comprise steel, couples to the delineator body and to the ball and socket joint, and is adapted to restore the delineator body to an upright position after removal of the deflecting force. An elastic grommet, which may comprise rubber, is also preferably included that connects the rod to the delineator body. The ball and socket joint may allow the delineator to deflect equally in all directions, or preferentially in a preferred deflection plane.
