  • Patent number: 4032248
    Abstract: An articulated highway delineator post assembly which includes an elongated, vertically extending indicator support post telescopingly engaged with a resilient slotted tubular sleeve. The support post is connected to the sleeve by a pivot pin assembly allowing pivotal movement of the support post about a horizontal axis to project a portion of the support post through the slot in the sleeve. The slot in the resilient sleeve is dimensioned in relation to the dimension of the support post to continuously resiliently urge the support post toward a vertical position when it has been inclined from the vertical at an acute angle upon pivotation and extension through a portion of the slot. The assembly further includes a ground post extended into the earth and projected at its upper end into one end of the tubular sleeve for supporting the sleeve and the support post above, and in substantially vertical alignment with, the ground post.
