  • Patent number: 8888302
    Abstract: A delineator includes a delineator body, a positioning member, and a reflective sheet. The delineator body and the positioning member include mounting features adapted to mate with each other at a plurality of positions corresponding to different positions of the positioning member on the delineator body. By selecting one of the different positions of the positioning member on the delineator body, the user can select a visibility configuration of the delineator. In some cases the reflective sheet may be bonded to the positioning member, so that the reflective sheet is positioned at a particular place on the delineator and visible to an observer when the positioning member is mounted in the selected position. In other cases the reflective sheet may be bonded to the delineator body, and the positioning member may cover one portion of the reflective sheet and leave another portion of the reflective sheet exposed to an observer.

  • Patent number: 8485753
    Abstract: Various self-cleaning delineator embodiments incorporate a delineator design that includes a shell portion, a core disposed inside the shell portion, and a reflective sheet coupled to an outer surface of the core. A wind turbine mounted on or in the delineator energizes a mechanical energy storage device, such as a spring, in response to wind or other air movement. A drive mechanism couples to the storage device and is adapted to use energy from the storage device to provide relative rotational motion between the shell portion and the core. A cleaning material disposed on an inner surface of the shell contacts the reflective sheet such that the relative rotational motion between the shell portion and the first core causes the cleaning material to slide across the reflective sheet to remove debris therefrom. The drive mechanism may include an escapement mechanism to limit the rotational motion to a maximum speed.

  • Publication number: 20120285368
    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.
