Pivoting vehicle barrier

A deflectable sign mounting, comprising upper and lower body portions:

• a tube portion, having an outer surface and upper and lower ends, for supporting the sign;
• an extension spring secured within the tube portion;
• a rocking base at the lower end of the tube portion;
• said tube portion, said extension spring and said rocking base together comprising an upper assembly with said tube portion and said rocking base comprising a unitary one-piece upper body portion;
• a stand-off member having an outer surface;
• the rocking base including a cylindrical part having an upper end and a circular disc extending outwardly from the upper end of said cylindrical part so as to overly said stand off member, extending outwardly beyond the outer surfaces of said tube portion and said stand off member;
• said stand-off member having a lower end and a stepped upper end receiving said cylindrical part for rocking engagement with the rocking base;
• a tether member engaging said extension spring, supporting said extension spring in an extended position;
• the rocking base and the upper end of the stand-off cooperating such that the upper assembly rocks about the stand-off upon application of a lateral force to the tube portion, causing a bias energy to be stored within said extension spring, biasing the rocking base toward its rest position upon removal of the dislodging force;
• and
• said stand off member and said rocking base each defining a central cross-shaped opening forming a passageway for receiving said tether member, confining said chain member so as to preserve the angular position of the tether member.
